COAL-CAR.
SPECIFICATION forming part of Letters 'Patent No. 272,550, dated February 20, 1883.
Application filed December 15, 1882; (No model.)
To all whom it may concern The letters E E2 indicate twotrap-fall doors,
Be it known that I, DAVID HOIT, of West that are located in the car-bottom at each side,
Albany, county of Albany, and State of New near the middle ot' the car, which are hinged York,haveinvented anew and usefullinproveto the sides ot' the car, and adapted to open 55 ment in Railway Goal-Gars, ot' which the foland close on their hinged connection e2, as inlowing is a specification. dicated by thedotted line c'ot Fig. 3, the trap- M y invention relates to that classot railwaym fall doors indicated at- E and E2 when closed cars which are designed to carry coal, are arbeingiii a lower plane than the doors D when ranged to be run up on skeleton tracks,and to the latter are swung up, the object of thus 6o 10 discharge their contents by means of hinged locating them below the others being to intrap-oors that drop. As the eight-wheel or crease the storage capacity ofthe cai-s between two-truck cars of this class have heretofore the trucks. been made, their iioors were constructed with The letters A' A indicate the inclined end centrallylocated and hinged trap-tall doors, floors of the car, which slope downwardly and o5 by means ot which they could be emptied of inwardly from where theyjoin the vertical ends but a part of their contents, they requiring to B until they reach the plane ot'the closed doors complete their discharge the employment of D. laborerswith shovels. Assuch carsweremade The letters A2 A2 indicate the inwardly-tatheir construction was necessitated by the pering portions of the car-sides opposite the 7o zo presence and position of the two trucks betrap-fall doors D', which also incline inwardly neath the car, which left but a restricted area from the vertical portion of the car-sides B2 for the bottom trap-falldoors. To remedy this until they reach the plane of the closed trapdiiculty and to construct the interior of an fall doors D'. eight-wheel car so that it will discharge all its The letters A3 A3 designate inclined parts 75 contents by means of bottom trap-fall doors ot' the sides of the car, which slope inwardly is the object of my invention. from the vertical portion ot' the car-sides B2 In the accompanying sheet of drawings, until they reach the lower plane ofthe closed forming a part of this specitication, there are doors E E2 at each side of the car. To opershown three ligures illustrating` inyinvention, ate these doors on their hinged connection, the 8o and in all of which the saine designation of ordinary chains,grip-shafts,ratchets,pawl-departs by letter-reference is used. tents, and cani-keepers are used, and which,
Figure 1 shows a. plan view of a two-truck broadly considered, and independentlyoftheir or eight-wheel car containing my invention. connection specially considered, are not my in- Fig. 2 illustrates the same carin a combined vention. Two shafts are employed-one for 85 longitudinal central vertical section and side each crossly-divided half of the car-and each elevation, one half being shown in the latter one of the shafts operates by connected chains, representation and the other half with the t'orone set ofthe end cross-hinged trap-fall doors, mer illustration, each cross-half of the car D D', and also the two opposite ones of the being the saine counterpart ofthe other. Fig. side hinged trap-fall doors that are indicated 9o 4e 3 is a two-part cross vertical section taken on at E' E2, and which are next adjacent to the the lines w x' Vand 002032 of Fig. l. end doors, D D. Th'ns each shalt operates The parts of the car as thus illustrated are one-halt' of the trap-fall doors, and each shaft designated by letter-reference, and their conand its connections is the counterpart ot` the vstruction explained as follows: other, and hence a description of one is a de- The letters D Dl indicate two trap-fall doors scription of both. located side by side at each end inthe bottom The two shafts are indicated at S S2, and of the car, and both of which are hinged to the each shaft at each end is provided with a ratchcar-bottom at right angles to the sides of the et-wheeI, R,pawldetent P, and cam-keeper K, car, so that they can be swung up and down and bearings for each shaft are constructed in roo y 5o on their hinged connection d', as indicated by the center brace and the vertical sides of the ,f the dotted line d2 of Fig. 1. car. The chains O' C' at one ot' their ends atchains C' C' a direct vertical hold on the latter doors, they pass laterally from the shafts toward the car ends over a cross-brace, M, from whence they descend in a perpendicular line to attach to the doors. The chains O2 C2 connect at one of their ends with the shafts, and at each of their other ends with one of the side hinged trap-fall doors E' E2. When the shafts are turned and the chains wound around them, the trap-fall doors are drawn up on their hinged connections to a horizontal position, where they form a part of the car-bottom to support its load, being held there by the engagement of the pawl-detent P, made with the ratchet-wheel It, (the latter being secured to the shalt,) and t-he engagement with the camlreeper and the pawl-detent.. When the keepers are raised and the detents tripped, the weight of the car contents opens the doors by nnrolling the chainsv from off the shafts, and the contents pass downwardly by gravity throughthedoors. 'Iherelativepositionof the latter and the construction ot' the inwardlyta pei-ing chute-form sides facilitate the emptying of the entire contents of the car, this better result (the dumping of the entire contents of a two-truck eight-wheel car) proceeding from the (littering construction and arrangement of parts which I employ, when compared with the older methods of constructing such cars for the same purpose, as before stated.
I am well aware that there is no novelty in hinging the trap-fall doors ot' dump-cars crosswise or lengthwise of thecars, and thatIcannot claim, broadly, either class of these constructions, or apart from the manner in which l arrange them relatively and construct the interior of the car in co-operating combination therewith, and their further combination as relatively placed, with the means employed to `operate them.
As I arrange and construct one shaft with four connected sets of chains to operate simultaneously four trap -fall doors, these factors would perform the same ofce in the same manner whether the trap-fill doors were in one horizontal plane when closed or in two differing planes when closed, as I illustrate them. Hence I do not limit my invention of the former to its combination with the latter, the object of having the side hinged doors in a lower plane than the doors which are hinged crosswise of the car being merely to increase the carrying capacity of car, as before stated, and
not for any co-operating function, otherwise;V
the trap-fall doors may be made to all have one horizontal plane in the car-bottom when closed, if desired.
As Iv construct the car interior with combined verticaland slopingsides and ends which taper inwardly to the plane of the closed doors, with two of the latter hung from each end ot' the car, and at right angles to the sides, and two of the trapfall doors hung from each side between the two trap-doors at each end, the
car interior, as thus constructed, would contain and dump its contents in the same manner whether the doors were operated as shown or by other equivalent means that would retain them horizontally and simultaneously release them. Hence I do not limit my invention as it relates to the construction of the car interior and its combined parts to their combination with the means employed to operate them.
To actuate so. as to hold connectedly and simultaneously to release by one shaft and four chains two of the end crosswise hinged trapfall doors, and the opposite ones of the side hinged trap-fall doors that are next adjacent to the former in each cross-halfof the car, with the shaft vertically over one set of the doors, and to secure a vertical attachment of the chains to the other, I construct and apply the crossbrace M, which has its top sheathed, for the passage of the chains (which connect with the doors that are not vertically beneath the shaft) until the chains are directly over such doors for vertical attachment, using a greater length of chain for making this connection than where the doors operated are directly beneath the shaft. y
Having thusfdescribed my invention, what I claim, and desire to secure by Letters Patent, 1s-
l. A two-truck eightwheel car interior in combination, consisting of the dropfall doors E' E' and Ez E2, hinged to the bottom of each of the inclined sides ofthe car that are opposite said doors, the drop-fall doors D' D' at each end of the car hinged to the bottom ot' the sloping ends of the car to swing therefrom crosswise of the latter, the vertical ends B, inwardly-sloping ends A' A', vertical sides B2, and inwardly sloping sides A3 A3, as herein shown and described.
2. The combination ofthe two trap-fall doors D D', hinged from the end of the car-bottom, so as to swing crosswise ot' the car, the two oppositely-placed side hinged trap-doors, E'E2, which are next adjacent to the aforesaid doors D' D', the shaft S', attached chains C' U' and C2 G2, and the brace M, arranged to operate as and for the purposes herein described and shown.
3. Thecombination of the two trap-falldoors D' D', hinged from the end of the car at the bottom, so as to swing crosswise of the car, the two opposite ones of the side hinged trapfall doors, E E2, which are next adjacent to the aforesaid doors D' D', the shaft S', attached chains C' U' and G2 2, the ratchets R, pawl-detents P, keepers K, and the cross-brace M, arranged to operate substantially as herein shown and described.
