- This invention relates to locomotive tender construction and more particularly toimprovements in the underframe and the tank.
- Another object of the present invention consists in the provision of a locomotive tender underframe formed of a single casting comprising a center sill, draft gear pocket, front 7 draw bar ful'crums, center-plates and side bearing support arms.
- Still another object- 'of the present invention consists in the provision of a locomo tive tender underframe formed as a single unitary casting combining all of the parts necessary; for supporting the tank, receiving the draft rigging, cooperating with the trucks, supporting the brake cylinder and performing all of the various functions usually perforin-ed by a complex fabricated underframe.
- a further object of the present invention consists in the provision of atender tank adapted to be supported byand secured to a single center sill Without the provision of side sills, end sills or full-width body bolsters.
- a still further object of this invention comprisesthe forming of a tender tank provided with internal bracing so arranged as to support the entire load of the tank and contents from a single center sill, provision being made to utilize the side plates of the tank as longitudinal vertical girders.
- Another and further object of the present invention consists in providing a'tender underframe formed as a single unitary casting without end or :side sills and so arranged as to receive a tank constructedeither for with body bolsters extending from the center-plates.
- the construction of such a frame combined with all attachments and brackets for auxiliary equipment is too com lex to be readily made in the form of a sing e casting, .and therefore itmust be fabricated either from rolled sections or from a number of separate castings, involving a plurality of machine operations and considerable riveting and bolting. With such a construction there is always the possibility of the failure of certain of the fastenings.
- the present invention has for its object the elimination not only of the side sills, but
- the frame can be made as a unitary cast-ing in the form of a box girder, the sides .and bottom of which may be provided with a plurality of openings for as a single casting, it has been found possible to combine in this casting, in addition to the parts already mentioned, the draft gear pocket, the front draw bar fulcrums,
- the tank end stops and the brake cylinder attaching means For use on railroads which scoop water while the engine is in motion, the necessary additional parts for the support of the scoop and its pneumatic operating cylinder and associated devices can be incorporated as a unitary part of the cast ng.
- the tank for use with t e above described underframe must be of special construction.
- the tank is substantially rectangular in cross section, following generally the conventional external shape and is interally braced so as to transfer the load, which is almost uniformly distributed over the bottom of the tank, entirely to the center sill, center-plate supports and side bearings support arms.
- the tank side plates arecaused to act as longitudinal, vertical girders which, b reason of their extreme depth, are quite e cient for this purpose.
- the slope sheet is extended and riveted to the side plates .or girders, thus forming in effect a transverse girder to prevent sagging of the sides of the tank which is supported at the bottom only along its longitudinal center.
- the arrangement and bracing of the tank is of extreme importance, for it is only by the use of such bracing that side sills, end sills and other parts can be eliminated to thus save a large amount of metal and weight.

- Figures 1, 3, 7, 10, 11. and 12 refer to a tender provided with an automatic stoker
- Figures 16 and 17 refer to a tender adapted for hand firing
- the remaining figures are generic 'to both tpes.
- the underframe disclose in the drawings is adapted without substantial modification for use either with a tank provided with an automatic stoker or with a tank intended for hand firing of the locomotive.
- the essential features of each tank are the same, there being but, a slight difference in the'front-end fastening means and in the provision, in one, of a'pocket to receive the stoking apparatus, which pocket, in the hand firing type is replaced by water spaces joined to the main portion of the tank.
- this underframe 20 is a one piece casting having the general form of a box girder, slightly longer than the tank which it is adapted to support. It is provided with the front and rear center-plate supports or-carriers 21 and 22, each. having a center-plate 23 on its bottom to engage with the corresponding truck bolster and to be securcd thereto by the usual kingpin (not shown). At the forward end there are provided the front draw bar fulcrums 24 cast integral with the underframe and adapted to receive the usual draft gear rigging of any suitable form and the chafing plate 25.
- the pocket 26 At the rear end there is the pocket 26 to receive any conventional type of draft rigging.
- the style of draft apparatus used at either end forms no part of the present invention, and will not be further described here, for the invention is only concerned with forming the pockets, to receive these two draft gears, as an integral part of the underframe.
- suitable openings such as 29 and 30 may be provided in the upper and lower plates of the sill for the purpose of lightening them where this can be done without reducing their strength. 4
- the tank front end stop is formed by the shoulder or abutment 36,
- abutment is formed by raising the forward end of the sill to incorporatein it the front draw bar fulcrums.
- the lower plate of the center sill is providedat 37 with the lugs 38 and the slots 39, the former serving to position the brake reservoir 40 and the latter to receive the brake reservoir.
- straps 41 for securing the reservoir to the frame The center sill forwardly of the brake reservoir attaching lugs, maybe provided with the bosses or lugs 42 for attaching the water scoop, where the tender is adapted for use on roads in which water is scooped while the locomotive is in motion.
- the scoop air-cylinder lug 43 adapted to have attached thereto the pneumatic cylinder for raising and lowering the scoop.
- the particular construction of the scoop and its associated parts forms no. part of the present invention, with the exception of the provision of integral parts, on the under- 7 frame to supportthe scoop and its mechanism.
- The-underframe 1s provided with a downwardly and forwardly sloping passage 44 through which the water from theqscoop and .the external scoop pipe 45 passes to the internal water scoop pipe 45 which is secured to the upper side of the center sill above the surface of the bottom plate of the water tank.
- the walls of this passage 44 are cast integral with the frame. Ahead of this passage on the leftside are the lugs 47' its the attachment of the air' brake cylind-er.
- the side bearing support arms 46 Extending laterally .from the forward center-plate support 21 are'the side bearing support arms 46, the upper surfaces of which lie in the. same plane as the top surface of the whole center sill so that they form in effect a short forward body bolster to assist the center sill in supporting-the tank.
- Sui-table means such as shown at 4? in Fig. 11 are provided for the attachment of the side bearings
- Similar side bearing support arms 48 are provided which function inthe same manner as the front ones to not only. support side bearings for the rear truck, but to form a short body bolster for the tank.
- the centerlate supports 21 and 22 are really formed y theintersection of the center sill with the body bolsters.
- the tenderunderframe comprises in effect only a single center sill, there being absolutely no end sills and no side sills.
- atransverse beam 49 for the sole purposeof supporting the rear steps 50.
- this rear step beam is formed-of two channels 51 with their wardly and secured together by the top cover plate 52 suitably riveted thereto.
- the lower flanges of these channels are riveted to a gusset plate 53 which is substantially triangular in forin and best shown in Fig.
- This gusset plate is received in the do pressed portion 54 of the top plate .of the center sill, as shown in Fig. 9, to which it is securely riveted to prevent any twisting grooves facing outof such a thickness and the depression 54 of such a depth that the top of the gusset plate is flush with the top surface of the center sill.
- Thisstep beam is definitely not an end sill, nor is it a rear stop for the tank, for it is spaced rearwardly of the tank approximately one-half inch and hence entirely independent thereof. -At the front end there is absolutely no transverse member. l i
- cushion strips are secured to the sill throughou t' its length
- These cushion strips comprise longitudinally extending wood members 55 hav-' ingtheir edges in the same plane as the the locomotive.
- the upper surfaces of the center sill, the center-plate supportsand the side bearing support arms lie in the same horizontal plane 2 and the cushion blocks and strips are all of the same thickness in .order that the underframe may support the tender tank 57, which has a flat or plane bottom 58.
- the tender tank externally is of the conventional shape and is'substantially rectangular in transverse cross section. It contains the water tank or compartment 59 and the coal'compartment 60 which is at the front end so as to be readily accessible to This coal compartment is separated from the water tank by theslope sheet 61, the construction here differing slightly'from the conventional in that the slope sheet extends clear to the side plates or coal compartment has its sides turned in ward near the top as shown at 64, and the slope sheet extends above and is secured to these inturned portions as shown at 65.
- the rear portion of the whole tank is lower than the front portion in order to retain the center of gravity as low as possible in the section containing the water, which is, of course, the heavier.
- Thside members 62 or plates of the tank extend the full length of the same and are reinforced in various places throughout their len th by vertical stifieners 66 to prevent buc ling.
- These stifieners may be in the form of angles or T-bars either riveted or welded to the inner surfaces of the side lates as best shown in Figs. 3, 4, 5, 6 and Being secured to the top plate 67 and the bottom plate or water bottom 58 of the tank, the side plates act to some extent as later described
- the slope sheet 61 by virtue of being extended and secured to the side plates, as disclosed in Fig. 7 at 63, acts as a transverse girder to support these side plates from the portion of the water bottom of the tank which rests upon and transfers the load to the center sill.
- the lower edge of the slope sheet is supported by the transverse partition wall 69 which separates the stoker feed" screw compartment 70 from the water tank to the rear of it.
- This compartment 70 is further isolated from the water tank b means of the longitudinal walls 71 secured at the rear to the partition wall 69 and running forward and being secured to the front sheet sections 72 which close the forward end of the tank.
- the upper edges of the walls 71 are secured in a watertight manner to the coal compartment side feed plates 73 which extend from the front walls 7 rearwardly and are 'oined to the slope-erect at 73'.
- the side coal feed plates 73 are reinforced on their under sides by the angle stifieners 76, certain of which are'continued downwardly alon the outer faces of the longitudinal walls 1, as shown at 77, to provide added strength. Gussets 7 8 connect the side coal feed plates 73 to the portions 63 and 64 of the side plates of the tank to reinforce them where. there is no top plate for that purpose, i. e. at the coal compartment.
- the internal bracing takes the form of a pair of struts on each side of the center sill.
- One of these, 81 transfers the loa from near the center plate to the top plate at 82, this member 81 being in tension. From tha point 82 the;
- the slope sheet 61 acts as a bolster which transpcses the load from the tension struts 84 the center sill close to where it is provided with the latitudinal projections which are used to support the side bearings for the front truck.
- the under side of the slope sheet is braced by the-struts 88, one on either side of the center, which transfer the weight 011 the slope sheet to the 1 struts from the top sheet to the center sill.
- the slope sheet is supported by the transversely and longitudinally inclined struts 89 which meet at the center and are there secured to the bottom plate to transfer the load directly to the center sill from two points arranged substantially one-third of the width of theslope sheet apart.
- the struts 88 and 89 not only support the load of the ,coal resting on the slope'sheet. but
- the sie plates are supported near the rear not 1 only by the rear plate 68 which rests on the center sill, but by the cast steelbracing members 79.
- the side plates are adequately supported. by the trans verse girder or bolster formed by. the slope sheet and its corresponding reinforcing members. They-are also supported by the side coal guide sheet-s 73-tand the conve er pocket sides .71 which have direct bearing -on'jthe short body bolster formed by the side bearing support arms, "Thus the side plates act as longitudinal, girders to transfer theremaining load by'iiyay of transverse girdersto the center s't1ll""over the centerplate supports. i,
- center-plate supports and side bearing support arms.
- the bottom plate is cut away beneath the conveyer screw pocket so that the rear edge of this opening together with the transverse plate or wall 69 abuts against the front end tank stops 35 .cast integral with the center sill.
- the length of the tank is so proportioned and the rear step beam 49 so positioned that when the tank is' cured down and held tightly against the I center sill by means of two bolts, one on either side of the center sill.
- These bolts 90 are best seen in Figs. 3,-14 and 15. Their upper ends are flattened in order that they may be secured by riveting to the end plate 68 and to the upturned flange 91 of the water bottom as shown sat/92. .
- the bolts pass through apertures in the gusset plate 53 and are threaded to receive the nuts 93 to hold the rear end of. the tank down.
- the front .end of the tank is secured to the underfram'e by the bolts 94 which pass through the flanges -95 of the reinforcing angles secured along the longitudinal edges of the opening in the bottom plate beneath of the corresponding side bearing support arm on its respective side of the center sill and anappropriate nut 97 is threaded onto thebolt' to retain the same in position.
- the tank is at all times securely drawn forward. against the front end stops by means of a pair of longitudinal bolts 98 which are best seen in Figs. 10, 11 and 13, one on either side of the center sill.
- Each of these bolts has a portion of its shank passing between the vertical flanges 99 of a pair of angles 100 which are riveted one on either side of the flange previously mentioned.
- the rear. edges of the flanges 99 are notched as-shown at 101 to receive the head of the bolt 98 and to prevent it from rotating;"'Tlie bfitdhs of thenotches 'are engaged by the under side of the head of the bolt to transfer the strain from.
- the bolt to the ngle'sahd thence to the bottom late of I olt. passes through.
- a nut 103' is threaded onto the bolt. 98 and. engages againstthe front face of-the side bearing support arm 50 that upon tightening the nut the tank may be drawn forward securely against the-front end stops.
- a closing sheet or front end plate 106 is provided as shown in Figures 16 and 17, and the front face of this sheet together with the forward edge of the bot tom plate 105 is adapted to cooperate with the shoulder or abutment 36 formed where the center sill is elevated to receive the front draw bar fulcrums to thus limit the forward movement of the tank under the action of the bolts 98 which are applied and operate in the same manner as just discussed in connection with the stoker type of tank.
- the forward end of the tank is, however, secured down to the center sill in a different manner, for vertical bolts cannot be applied through the side bearing support arms as will be obvious when it is considered that the eonveyer screw pocket 70 is now occupied by water.
- reinforced angle members 107 are securely riveted to the outside of front sheet 106 and their horizontal flanges are bored to receive the bolts 108 which pass down through openings 109 formed in the bosses 110 on the sides of the center sill just to the rear of the front draw bar fulcrums. These openings are best shown in Figs. 8 and 17.
- an internal supporting strut 111 may be provided having a flange secured behind the angles 107 by the same rivets which hold them in place and having a second flange 112 which is secured to the bottom plate.
- the stops 35 must be removed from the center sill and the abutment then acts as a front end tank stop, for the water bottom extends clear to the. front of the tank throughout its full width; This is the only When a tank difference in construction required in the underframe.
- the bolt holes for receiving the front end holding down bolts occur in each type of frame, and a proper set may be readily selected for use.
- the present invention consists of a novel and simplified tender and construction wherein the underframe is reduced to a single unitary casting having but a center sill and a pair of transverse members resembling short body bolsters.
- a novel form of tank has been invented to cooperate with the single center sill and to be supported in such a manner as to eliminate strains on the water bottom due to its large overhang laterally from the center sill. Portions of the water bottom lacking direct support from beneath by the usual underframe parts are adequatelysupported by internal bracing members indirect y transferrin the load to the center sill and the short body bolsters.

LOCOMOTIVE TENDER.
Application filed December 24, 1925. Serial No. 77,567.
This invention relates to locomotive tender construction and more particularly toimprovements in the underframe and the tank.
It is the general object of the present invention to provide a novel and improved locomotive tender in which thedesign is materially simplified, the weight reduced and the cost of construction lowered.
More particularly it is an object of the present invention to provide a locomotive tender underframe composed of a single casting forming only a center sill for supporting the tank.
Another object of the present invention consists in the provision of a locomotive tender underframe formed of a single casting comprising a center sill, draft gear pocket, front 7 draw bar ful'crums, center-plates and side bearing support arms.
Still another object- 'of the present invention consists in the provision of a locomo tive tender underframe formed as a single unitary casting combining all of the parts necessary; for supporting the tank, receiving the draft rigging, cooperating with the trucks, supporting the brake cylinder and performing all of the various functions usually perforin-ed by a complex fabricated underframe. A further object of the present invention consists in the provision of atender tank adapted to be supported byand secured to a single center sill Without the provision of side sills, end sills or full-width body bolsters. A still further object of this invention comprisesthe forming of a tender tank provided with internal bracing so arranged as to support the entire load of the tank and contents from a single center sill, provision being made to utilize the side plates of the tank as longitudinal vertical girders.
Another and further object of the present invention consists in providing a'tender underframe formed as a single unitary casting without end or :side sills and so arranged as to receive a tank constructedeither for with body bolsters extending from the center-plates. The construction of such a frame combined with all attachments and brackets for auxiliary equipment is too com lex to be readily made in the form of a sing e casting, .and therefore itmust be fabricated either from rolled sections or from a number of separate castings, involving a plurality of machine operations and considerable riveting and bolting. With such a construction there is always the possibility of the failure of certain of the fastenings. At the same time the cost of construction is materially increased due to the attendant difliculties' in constructing such a frame. It has heretofore been presumed that side sills and end sills were necessary to properly support and reinforce. the tank to prevent the same from sagging under its great load of water which is particularly susceptible to shifting and surging on rough tracks, when rounding curves and'when going up and down grade.
The present invention has for its object the elimination not only of the side sills, but
also of the end sills, and a material reduc tion in the length of the body bolsters, thus reducing the frame to a single center sill with shortprojections from the center-plate supports to-carry'the side bearings, whichprojections act as short body bolsters to assist in the support of the tank. 'With this 85 simple construction, the frame can be made as a unitary cast-ing in the form of a box girder, the sides .and bottom of which may be provided with a plurality of openings for as a single casting, it has been found possible to combine in this casting, in addition to the parts already mentioned, the draft gear pocket, the front draw bar fulcrums,
the center-plate supports,the center-plates,
the tank end stops and the brake cylinder attaching means. For use on railroads which scoop water while the engine is in motion, the necessary additional parts for the support of the scoop and its pneumatic operating cylinder and associated devices can be incorporated as a unitary part of the cast ng.
The tank for use with t e above described underframe must be of special construction.
It is substantially rectangular in cross section, following generally the conventional external shape and is interally braced so as to transfer the load, which is almost uniformly distributed over the bottom of the tank, entirely to the center sill, center-plate supports and side bearings support arms. In so doing the tank side plates arecaused to act as longitudinal, vertical girders which, b reason of their extreme depth, are quite e cient for this purpose. In addition to the above reinforcing and bracing means, the slope sheet is extended and riveted to the side plates .or girders, thus forming in effect a transverse girder to prevent sagging of the sides of the tank which is supported at the bottom only along its longitudinal center. The arrangement and bracing of the tank is of extreme importance, for it is only by the use of such bracing that side sills, end sills and other parts can be eliminated to thus save a large amount of metal and weight.
Other and further objects of the present invention will be disclosed and more fully discussed in the following specification and accompanying drawings wherein is shown a single exemplary embodiment of the present invention with the understanding, however, that various changes may be made therein without departing from the'spirit of the invention or the scope of the appended claims.

Figure 16 is a partial longitudinal vertical section, showing the means of securing the front end of the tank to the underframe on tenders adapted for hand tiring; and
Figure 17 is a partial transverse vertical section on the broken line 17.-17 of Fig. 16. Figures 1, 3, 7, 10, 11. and 12 refer to a tender provided with an automatic stoker, whereas Figures 16 and 17 refer toa tender adapted for hand firing, and the remaining figures are generic 'to both tpes. The underframe disclose in the drawings is adapted without substantial modification for use either with a tank provided with an automatic stoker or with a tank intended for hand firing of the locomotive. The essential features of each tankare the same, there being but, a slight difference in the'front-end fastening means and in the provision, in one, of a'pocket to receive the stoking apparatus, which pocket, in the hand firing type is replaced by water spaces joined to the main portion of the tank. The
space necessary for the automatic conveyer screw of the stoker is somewhat longer than the usual shovel plate adapted for hand firing, and hence in the two ty es of tanks the sections illustrated by way 0 example in the drawings may be somewhat displaced longitudinally of the tender, but are otherwise identical.
v The underframe, which is substantially identical in construction for both the 'stoker and non-stoker types of tank, ,will be first described. 2 Referring to the drawings, it will be seen that this underframe 20 is a one piece casting having the general form of a box girder, slightly longer than the tank which it is adapted to support. It is provided with the front and rear center-plate supports or- carriers 21 and 22, each. having a center-plate 23 on its bottom to engage with the corresponding truck bolster and to be securcd thereto by the usual kingpin (not shown). At the forward end there are provided the front draw bar fulcrums 24 cast integral with the underframe and adapted to receive the usual draft gear rigging of any suitable form and the chafing plate 25. At the rear end there is the pocket 26 to receive any conventional type of draft rigging. The style of draft apparatus used at either end forms no part of the present invention, and will not be further described here, for the invention is only concerned with forming the pockets, to receive these two draft gears, as an integral part of the underframe. Between each draft gear p cket and the adjacent center-plate supdrawing and stopping of the tender and the train connected to the rear of it. vIf desired, suitable openings such as 29 and 30 may be provided in the upper and lower plates of the sill for the purpose of lightening them where this can be done without reducing their strength. 4
. Between the center-plate. supports, there is also but a single center sill which is.
likewise in the form of a box girder provided with various lightening apertures 31,
32, 33 and 34in its upper plate. The upper plate is also provided, to the rear of the front center-plate support, with the tank end stops 35 cast integral therewith and projecting vertically upward for a purpose to be hereinafter described. These tanli end, stops are not used when the underframe supports a tank ofthe non-stoker type and can therefore be left off. .In' the case of non-Stoker tanks, the tank front end stop is formed by the shoulder or abutment 36,,
best shown in Figs. 3 and 8, which abutment is formed by raising the forward end of the sill to incorporatein it the front draw bar fulcrums.
The lower plate of the center sill is providedat 37 with the lugs 38 and the slots 39, the former serving to position the brake reservoir 40 and the latter to receive the brake reservoir. straps 41 for securing the reservoir to the frame The center sill forwardly of the brake reservoir attaching lugs, maybe provided with the bosses or lugs 42 for attaching the water scoop, where the tender is adapted for use on roads in which water is scooped while the locomotive is in motion. Just to the rear of these lugs 42 is the scoop air-cylinder lug 43, adapted to have attached thereto the pneumatic cylinder for raising and lowering the scoop.
The particular construction of the scoop and its associated parts forms no. part of the present invention, with the exception of the provision of integral parts, on the under- 7 frame to supportthe scoop and its mechanism. The-underframe 1s provided with a downwardly and forwardly sloping passage 44 through which the water from theqscoop and .the external scoop pipe 45 passes to the internal water scoop pipe 45 which is secured to the upper side of the center sill above the surface of the bottom plate of the water tank. The walls of this passage 44 are cast integral with the frame. Ahead of this passage on the leftside are the lugs 47' its the attachment of the air' brake cylind-er.
Extending laterally .from the forward center-plate support 21 are'the side bearing support arms 46, the upper surfaces of which lie in the. same plane as the top surface of the whole center sill so that they form in effect a short forward body bolster to assist the center sill in supporting-the tank. Sui-table means such as shown at 4? in Fig. 11 are provided for the attachment of the side bearings At the rear centerplate support 22 similar side bearing support arms 48 are provided which function inthe same manner as the front ones to not only. support side bearings for the rear truck, but to form a short body bolster for the tank. The centerlate supports 21 and 22 are really formed y theintersection of the center sill with the body bolsters. From the above description it will be seen that the tenderunderframe comprises in effect only a single center sill, there being absolutely no end sills and no side sills. There are, however, two integral body bolsters, but these are much shorter than the usual body bolsters and extend laterally'only a sutficient distance to provide support for the side bearings, and a wider base for the main internal tank bracing. t
At the extreme rear of the center sill and justabove the draft gear pocket, there is provided atransverse beam 49 for the sole purposeof supporting the rear steps 50. Referring to Figs. 14 and 15 it will be seen that this rear step beam is formed-of two channels 51 with their wardly and secured together by the top cover plate 52 suitably riveted thereto. The lower flanges of these channels are riveted to a gusset plate 53 which is substantially triangular in forin and best shown in Fig.
14. This gusset plate is received in the do pressed portion 54 of the top plate .of the center sill, as shown in Fig. 9, to which it is securely riveted to prevent any twisting grooves facing outof such a thickness and the depression 54 of such a depth that the top of the gusset plate is flush with the top surface of the center sill. Thisstep beam is definitely not an end sill, nor is it a rear stop for the tank, for it is spaced rearwardly of the tank approximately one-half inch and hence entirely independent thereof. -At the front end there is absolutely no transverse member. l i
In order to provide a cushion for the tank and to take up slight irregularities in thetop surface of the center sill, cushion strips are secured to the sill throughou t' its length These cushion strips comprise longitudinally extending wood members 55 hav-' ingtheir edges in the same plane as the the locomotive.
apart along the'longitudinal center of the sill as best shown in Figs. 3, 4 and 5. Over the side bearing support arms are similar blocks of wood 56 to provide support for the tank clear to the ends of these arms. These blocks may best be seen in Figs. 4, 10 and 12.
The upper surfaces of the center sill, the center-plate supportsand the side bearing support arms lie in the same horizontal plane 2 and the cushion blocks and strips are all of the same thickness in .order that the underframe may support the tender tank 57, which has a flat or plane bottom 58.
- The tender tank externally is of the conventional shape and is'substantially rectangular in transverse cross section. It contains the water tank or compartment 59 and the coal'compartment 60 which is at the front end so as to be readily accessible to This coal compartment is separated from the water tank by theslope sheet 61, the construction here differing slightly'from the conventional in that the slope sheet extends clear to the side plates or coal compartment has its sides turned in ward near the top as shown at 64, and the slope sheet extends above and is secured to these inturned portions as shown at 65. The rear portion of the whole tank is lower than the front portion in order to retain the center of gravity as low as possible in the section containing the water, which is, of course, the heavier.
Thside members 62 or plates of the tank extend the full length of the same and are reinforced in various places throughout their len th by vertical stifieners 66 to prevent buc ling. These stifieners may be in the form of angles or T-bars either riveted or welded to the inner surfaces of the side lates as best shown in Figs. 3, 4, 5, 6 and Being secured to the top plate 67 and the bottom plate or water bottom 58 of the tank, the side plates act to some extent as later described The slope sheet 61 by virtue of being extended and secured to the side plates, as disclosed in Fig. 7 at 63, acts as a transverse girder to support these side plates from the portion of the water bottom of the tank which rests upon and transfers the load to the center sill. The lower edge of the slope sheet is supported by the transverse partition wall 69 which separates the stoker feed" screw compartment 70 from the water tank to the rear of it. This compartment 70 is further isolated from the water tank b means of the longitudinal walls 71 secured at the rear to the partition wall 69 and running forward and being secured to the front sheet sections 72 which close the forward end of the tank. The upper edges of the walls 71 are secured in a watertight manner to the coal compartment side feed plates 73 which extend from the front walls 7 rearwardly and are 'oined to the slope-erect at 73'. These si e feed plates together with the slope sheet tend to directthe coal onto the diaphragm 74, from whence it passes through the longitudinal slot 75- inthis diaphragm and into the conveyer screw pocket 70. The construction and operation of the conveycr and stoking apparatus form no part of the present invention and have neither been shown in thedrawings nor described inthis specification.
The side coal feed plates 73 are reinforced on their under sides by the angle stifieners 76, certain of which are'continued downwardly alon the outer faces of the longitudinal walls 1, as shown at 77, to provide added strength. Gussets 7 8 connect the side coal feed plates 73 to the portions 63 and 64 of the side plates of the tank to reinforce them where. there is no top plate for that purpose, i. e. at the coal compartment.
To transfer the load ofithe tank and in the tank to the center sill and to'the centerplate supports and side bearing support arms without rel'ing on the water bottom as a transverse bracing members or struts which are best disclosed in Figs. 3, 4, 5 and 6. Over the rear center-plate support 22 are arranged the cast steel struts 79 which transfer the load from near the rear ends of the side plates earn, resort is bad to internal ate the center sill and the edge of the bottom near this section. owing to the lateral arms which support the side bearings and serve also as short body bolsters to prevent flexing of the water bottom. i
At=-intermediate sections such as those disclosed in Fig. 5, where there are no lateral projections from the center sill. the internal bracing takes the form of a pair of struts on each side of the center sill. One of these, 81, transfers the loa from near the center plate to the top plate at 82, this member 81 being in tension. From tha point 82 the;
of the'unsupported portion of the bottom 1 5 load is transferred directly to the center? -sill by the com ression strut '83..
Referring to igure 6, it will be seen that -tion 86, which is longitudinally inclined, to-
gether with the slope sheet 61 acts as a bolster which transpcses the load from the tension struts 84 the center sill close to where it is provided with the latitudinal projections which are used to support the side bearings for the front truck. The under side of the slope sheet is braced by the-struts 88, one on either side of the center, which transfer the weight 011 the slope sheet to the 1 struts from the top sheet to the center sill.
bottom plate just beyond its support by the center sill and also prevent its buckling due to surging of the water. Still further forward the slope sheet is supported by the transversely and longitudinally inclined struts 89 which meet at the center and are there secured to the bottom plate to transfer the load directly to the center sill from two points arranged substantially one-third of the width of theslope sheet apart. The struts 88 and 89 not only support the load of the ,coal resting on the slope'sheet. but
prevent it from buckling while performing.
its duty as a transverse girder, and also act asa means of transferring certain of the water load placed thereon by the tension ,The bottom plate or water bottom 58 of the complete tank is of much heavier metal than the side plates since it is subject to a greater load and has secured thereto the various load transferring members. Referring particularly to Figs. 3,4, 5 and 6, it will be seen that a large part of the lo'ad on the bottom plate is transferred directly or indirectly to the center..si ll,-leaving but a small portion to be absorbed by the sideplates in their function as longitudinal. vertical irders. As. previously pointed out,
.the sie plates are supported near the rear not 1 only by the rear plate 68 which rests on the center sill, but by the cast steelbracing members 79. Near the front, the side plates are adequately supported. by the trans verse girder or bolster formed by. the slope sheet and its corresponding reinforcing members. They-are also supported by the side coal guide sheet-s 73-tand the conve er pocket sides .71 which have direct bearing -on'jthe short body bolster formed by the side bearing support arms, "Thus the side plates act as longitudinal, girders to transfer theremaining load by'iiyay of transverse girdersto the center s't1ll""over the centerplate supports. i,
Referring to Fig. 1, itwill be "seen that center-plate supports and side bearing support arms. The bottom plate is cut away beneath the conveyer screw pocket so that the rear edge of this opening together with the transverse plate or wall 69 abuts against the front end tank stops 35 .cast integral with the center sill. The length of the tank is so proportioned and the rear step beam 49 so positioned that when the tank is' cured down and held tightly against the I center sill by means of two bolts, one on either side of the center sill. These bolts 90 are best seen in Figs. 3,-14 and 15. Their upper ends are flattened in order that they may be secured by riveting to the end plate 68 and to the upturned flange 91 of the water bottom as shown sat/92. .The bolts pass through apertures in the gusset plate 53 and are threaded to receive the nuts 93 to hold the rear end of. the tank down.
The front .end of the tank is secured to the underfram'e by the bolts 94 which pass through the flanges -95 of the reinforcing angles secured along the longitudinal edges of the opening in the bottom plate beneath of the corresponding side bearing support arm on its respective side of the center sill and anappropriate nut 97 is threaded onto thebolt' to retain the same in position.
' The tank is at all times securely drawn forward. against the front end stops by means of a pair of longitudinal bolts 98 which are best seen in Figs. 10, 11 and 13, one on either side of the center sill. Each of these bolts has a portion of its shank passing between the vertical flanges 99 of a pair of angles 100 which are riveted one on either side of the flange previously mentioned. The rear. edges of the flanges 99 are notched as-shown at 101 to receive the head of the bolt 98 and to prevent it from rotating;"'Tlie bfitdhs of thenotches 'are engaged by the under side of the head of the bolt to transfer the strain from. the bolt to the ngle'sahd thence to the bottom late of I olt. passes through. a substantially longi-' tudinal aperture 102 cored 'into the side bearing support arm inside of the opening for the reception of the bolt'94. A nut 103' is threaded onto the bolt. 98 and. engages againstthe front face of-the side bearing support arm 50 that upon tightening the nut the tank may be drawn forward securely against the-front end stops.
tank. The forward end of each Y 'The above described tank and. securing .the tank rests freely on top ofth'e center sill, means are 10: tenders equipped with auto-' "used with a stoker type tank, it is tom plate and therefore no rear edge of such veyer screw pocket is eliminated and this space is occupied by a compartment connected to the part of the tank for the reception of the water. For this reason there is no opening or longitudinal slot 104 in the botslot to cooperate with the front end tank stops 35. These stops are therefore removed from the casting to make room for the flat water bottom sheet 105 of the tank as shown in Fig. 16. A closing sheet or front end plate 106 is provided as shown in Figures 16 and 17, and the front face of this sheet together with the forward edge of the bot tom plate 105 is adapted to cooperate with the shoulder or abutment 36 formed where the center sill is elevated to receive the front draw bar fulcrums to thus limit the forward movement of the tank under the action of the bolts 98 which are applied and operate in the same manner as just discussed in connection with the stoker type of tank. The forward end of the tank is, however, secured down to the center sill in a different manner, for vertical bolts cannot be applied through the side bearing support arms as will be obvious when it is considered that the eonveyer screw pocket 70 is now occupied by water. Therefore, reinforced angle members 107 are securely riveted to the outside of front sheet 106 and their horizontal flanges are bored to receive the bolts 108 which pass down through openings 109 formed in the bosses 110 on the sides of the center sill just to the rear of the front draw bar fulcrums. These openings are best shown in Figs. 8 and 17. To strengthen the meeting corner of the bottom and front plate and to more firmly support the angles 107, an internal supporting strut 111 may be provided having a flange secured behind the angles 107 by the same rivets which hold them in place and having a second flange 112 which is secured to the bottom plate.
The interchangeability of the two forms of tanks with regard to the underframe will be readily apparent. When the frame is rovided with two front end tank stops. f these only the rearmost one,- 35, is effective to cooperate with the tank, for the front end of t e central ortion of the water bottom is cut away an will not contact with the abutment formed by the elevation of the front fropt draw bar fulcrums.
ldlpted for hand firing is applied to the end of the center sill to accommodate the underframe, the stops 35 must be removed from the center sill and the abutment then acts as a front end tank stop, for the water bottom extends clear to the. front of the tank throughout its full width; This is the only When a tank difference in construction required in the underframe. The bolt holes for receiving the front end holding down bolts occur in each type of frame, and a proper set may be readily selected for use.
From the above description, it will be evident that the present invention consists of a novel and simplified tender and construction wherein the underframe is reduced to a single unitary casting having but a center sill and a pair of transverse members resembling short body bolsters. A novel form of tank has been invented to cooperate with the single center sill and to be supported in such a manner as to eliminate strains on the water bottom due to its large overhang laterally from the center sill. Portions of the water bottom lacking direct support from beneath by the usual underframe parts are adequatelysupported by internal bracing members indirect y transferrin the load to the center sill and the short body bolsters. The construction of the tank is no more complicated than that of the conventional tank, and the weight is substantially the same, whereas the underframe has been materially reduced in both size and weight, and the constructional difficulties encountered in more complex frames have all been eliminated, whereb there is a material reduction in Weight of t e whole tender and a decrease in the cost of construction of the same. WVhile specific embodiments of the invention have been illustrated and described, it is to be understood that these are only exemplary, and that changes and modification in the same may be made by those skilled in the art without departing from the spirit of the invention as set forth in the following claims.
