To alf; 'whom it ma" concern.'

lle it known that I, ANDREW H. REEDER, a citizen of the-United States, residing at Stonega, in the county of 7iVise and State ot' Virginia, have invented new and useful improvements in Coke-Drawers, of which the following is a specification.

The present invention is an improvement in machinery for pulling or "discharging coke from coke ovens, more generally known as `:coke drawers, and its principal objcct,broadly -stated,comprehends the production of a highly efficient and readilyoperated machine constructed in such a manner that the beam or that element which corresponds thereto, is capable not only of being raised and lowered bodily, but also of being swung in both a horizontal and avertie-al plane. TL-iere is thus )roduced, in elt'cct, a universal mounting o the beam which enables the shovel or'other tool to reach all portions of the oven.

Furthermore, the invention contemplates the production of a coke drawer wherein the reciprocatory movement of the beam and the various adjustments thereof, are effected by means of an operating tluid, suitably supplied to the. several operating mechanisms, the supply being controlled by speeially constructed devices.

The invention still further resides in the employment of a specially constructed I nechanisin by means of which the bodily Inove- Vment of the machine along the battery of ovens is obtained, such mechanism. like the aforo-mentioned adjusting mechanisms, being duid-operated.

'Finally the invention comprehends the production and employment of a special torni of shovel, the parts of which bear a definite relation to each other and operate in :i particular manner.

A structural embodiment of die invention is illustrated in the accompanying drawings whereof- Figure l is an end elevation ot the coniplete machine showing the beam in its projected position, with the shovel within one of the ovens, the latter appearing in section. Figz is an enlarged plan view of the niaciiine. parts thereof being broken away. Fig. 3 is an enlarged side elevation. F ig.

Fi (3 1s a plan view of the shovel carried by the beam. Fig. 7, 8 and 9 are side elevations showing the three positions assumed by the parts of the shovel when the latter is operated. Fig. ,10 is a front elevation of Fig. 7. Fig. 1l is an enlarged fragmental view 'illustrating the connection between the devices oroperating the main valve and one of the valves which control the swinging movement of the beam. Fig. '1Q is a vertical section taken transversely of Fig. 11. Figs. 13 and 14 are detail perspective views of tools w ich may be substituted for the shovel.

Reference being had to the drawings, and to the characters marked thereon, .i designates in a general manner one of a batteriP of coke ovens; B the track arranged in frontI of said ovens; and C the carriage which travels along the track and supports the various operating mechanisms of the drawer. These mechanisms comprise the beam and beam-cylinder designated by the character l), the vertical-rocking mechanism E, the horizontal-saivinging mechanism I", the litting-jack (ir, and the traction mechanism ll. The coke ovens are ot' the ordinary conf-'truction and require, therefore, no extended de.- scription. The track B parallels these ovens. as is customary.- rl`he carriage C is in the form of an ordinary four-wheel truck. and its platform l is supported upon the axles 2 and -l, as shown best in Figs. 3 and l.

The mechanism I) comprises a c vlinder 4 supported centrally of its length by horizontal trmmions 5, joui-nailed iu bearings G with which a casting 7 is provided. This casting is formed or otherwise rigidly` mounted upon the upper end of a tubular metal element 8 which acts as the cylinder of the lifting-jack (l. hereinafter described, and is formed at its lower end with a continuous lateral flange 9, said flange serving to support a turn-table 10. lVithin cylinder l there are arranged main and supplemental pistons 11 and 12. The rod portion 13 of piston l1 forms the beam of the machine and. as such. is designed to carry at its outer end a shovel or other tool. It is hollow or tubular` as shown in Fig-4, and receives within its bore the supplemental piston 12 which is lil stationary and has the rear end of vits rod portion ll rigidlvsecured to the rear head of cylinder l. The hores ot the two rods I3 and lvl are continued through the piston heads t5 and 1G.

The beam, or more properly, the. main pis ton is operated by fluid pressure admitted on opposite sides of its head l5 by means of a pair of pipes` 1T and IS. The. presented, or inner ends of thcsc pipes open into a main valve chest lll, while their outer ends are rc- -ceived in ports .tl and 2l' formed adjacent the opposite ends ot the cylinder. The operating lluid` which may be either compressed air or steam, pretcrablv,the former, enters the valve chest through a pipe 22 connected by :s short length ot rubber hose, 23 with a pipe 2l to which. in turn, is connected a second hose pipe 2. lipe 25 is connected to a pipe 2li mounted on the platfornrl of the carriage and designed tor connection by means of a removable. hose pipe with the branch 2S of a continuous supply pipe or main 29 located near the top of the battery of ovens. there being` as .fili be understood` a` separate branch pipe. for each oven. There.

is also located in front of cach oven a standpipe il() which communicates with an under- `rround \\'ater-znain (not shown).

'ithin the valve-chest. il) is arranged a sliding D-valve lll opt rated manually by a rod 82 having: at the outer end thereof a handle This valve is shown in its position of rest in lug, 4, wherein both of the inlet passages and 236 formed in the bottom wall' of the. chest are closed, the exhaust passage 34 being;u continuously open. The main inlet, pipe QG is provided at its outer end with a valve T57 which controls the tion' of the operating"l fluid into said pipe when the latter is connected up with one of the branch pipes Q8. Valve 3l controls the pas# sage ot the fluid fron; the chest into the nterior of the maincylindcr 4, upon one side or the other of `the main piston head 15, and hence by reciprocating the valve rod 32, a similar movement will he imparted to the beam or main piston.

The mechanism E for swinging or tilting:r the beam cylinder 4 in a vertical plane com prises essentially an upright cylinder 3S, having a trunnion or hinge-connection 39 at its loiver end with the turn-table 10 and having its piston rod 40 pivotally connected at. its upper end, as indicated by the numeral 41, to a collar 42 secured to seid beam cylinder. The movement of the piston rod 40 is controlled by a slide valve 43 located within a Valve chest 44 attached to cylinder 38, to which chest the operating fluid is supplied through a hose pipe 45 communicating with the supply pipe 22. Valve 43 is connect-ed by a link 46 to an arm 47 secured to a .shaft 48 journaled in brackets 49 and 50 fastened to cylinder 38. Shaft- 48 carries a l l l second arm 5l which is arranged atan angle to arm -l and is connected by a rod 52 with the adjacent arm of an angle lever 58 fulcrumed upon one of the trunnons 5. Lever 13 has its other to a curved lever arm formed at; end with a. lateral sleeve 5G, irl; being universally jointed to the above mentioned arms. Sleeve 5G is arranged bctwecn two spaced brackets connected together at, their lower ends and clamped to cylinder 4 by U-bolts 58, the .space between said brackets being slightly greater than the length ofsaid sleeve, so as to gwrmit a limited movement otthc latter in either direction (sec Fig. 1l). This .sleeve it titled upon an elongated sleeve 5S) rigidly secured in any desired manner to valve. rod 532 and having its ends projecting loosely through openings formed in brackets 57, owingy to which construction it will be understood that said valve rod is l1-1s supported by the brackets. Sleeve 59 has formed in its upper surface a. longitudinal key-way (l0 which extends almost the entire length thereof, 'and receives the reduced lower ends of a pair of screws (il tap ed into sleeve 56. It is therefore apparent t iat both valves 3l and 43 are operable by a single clement, namely, rod 32, an endwisc movementof said rod servingr to shift, valve 31, while a rotary movement will raise or lower valve l2-l. .fth reference to the operation ot the. latter valve, it may he stated that a rockingf moven'ient of lever 55 (effected b v turning or rotating rod 32) Will roch angle lever 53 through its link connection '54 therewith; lever Sil. on being rocked, will rock the angle lever formed by shaft 4S and its arms 5l and 47, the second arm being connected h v link 46 to said valve 43. The mechanism F for imparting a lateral or horizontal `tviaging movement to the beam and beam cylinder comprises a horizontal cylinder 62 supported intermediate its ends by a U-shaped casting or bracket (t3. provided at. the upper ends of its legs with bearings for the horizontal trunnions G4 secured to said cylinder. The base p0rtion of this bracket (33 has an integral bear` ing sleeve or boss 65 which is received in a. seat 6G formed in a casting 87 carried by the platform This hearing sleeve' or boss is also provided with a depending pin (i8 extending through openings in the casting' and bracket. and having' a nut Gt) threaded on the, lower (nd thereof. Hence, it will be apparent that the cylinder is capable. of rocking movement in both a. vertical and a horizontal plane, so as to accommodate itself to the various movements of the beam cylinder.

The piston 7 O movable within cylinder 62, has the outer end of its rod 71 connected to a. radial extension 72 formed upon the turnv table 1l). The Huid for operating said piston its upper the ends of link arm connected by a link 5l 57 integrally 1 is adnlitted into c vlinder (32 fron'i a valve chest Tit. mounted thereon. lluill being supplied to said chest b v a hose pipe T4 which ont-us at one end tliereiuto and at. the other end into a lateral branch T) of pipe 2li. (`he t Ti', is t'ornied with a pair of inlet passages Tt'i and TT. and au exhaust passage TS. the openings to these passages benign1 controlled b v a slide valve T2) operated by a rod St). Conlnlunication is had between passage TT and the. cylinder tiL. by a pipe Sl, and between passage Tt and said c vliuder b v a passage 5; t'ornied ill the latter, the` lluid being admitted ilito the opposite ends ot' the c vlinder as shown in Fig. il. liod t) is supported b v a bracket. S23 attached to said cyl inder and is provided at its outer end with a handle tief.

'l`o raise or lower the turn-table and the several nierhanisnis niounted thereon. there is provid d the jack (i. This nierlianisni includes. in addition to the cylinder S. (upon the flange S of which the turn-table rests. as atrend)v stated) a solid vertical piston S5 which is t'orined as au integral part of i casting nti rigidly secured to plattorili l. ri`lie upper end ot' said pieton terliiinates short ot' tli-it ot' the cylinder thereb)v providing' a Huid-receiving chauiber ST (see Fig. t). 'l`he lluid Yfor operating the jack ina)Y be either air or water. the latter being! considered preferable.

l'poli the turn-table. aild adjacent to the vertical c vlinder 3S. there is niounted an air-tight closed tank S5. through the upperend ot' which project two pipes S9 and 90. lipe S9 opens at its upper end into pipe 2-1 (see Fils. l and 5) and extends only a very short distance into tlie tam. ipe 90 extends close o the bottom of the tank and is in eoniinunication at its upper end with chamber 8T by way of a separate pipe 91 having: a valve 92 arranged therein. Said pipe 90 is provided adjacent its upper end with a lateral branch 9S connected by a hose-pipe at) with a pipe 100 arranged pai-al` lel with pipe :2G and having at its outer end a valve 101. Pipe 100 is adapted to be connected with one of the .child-pipes 30 when the tank to be filled, such connection being poasible either by ineans of a separate hose pipe 102 or by the detachable hose pipe 2T. according: as circumstances may require.

Villen the jack is to be operated hydraulically (it being anders lod that the tank has previously been filled with water lo the desii-ed level, which is below the end of pipe S9. and that air has been introduced luto the upper portion of the tank) it is only necessary to open valve 92. whereupon the pressure of the air will force the Water ui'iwardlj.r through pipe 90 into pipe 91 and thence into clianiler 8T. The water entering said chamber 'iviil gradually force cylinder 8 upwardly, the cylinder carrying with it the i connected to the rear axle 3.

turn-table and the mechanisms mounted upon the latter. When the required height luis been reached, valve. ft2 is closed, whereupon said table. will he retained in adjusted position. ll' the air stored within the tank be under high pressure, it will ol' itself bv sallirient to operate the jack as above desrriberi; otherwist; it will be necessary to introduce au additional quantity of air into the tank through pipes 2. 2l and Si). lt. will be apparent.-however, that the, jack niaj.' be operated pneiunatically, when the ianlt' is einptv ol water by introducirlo air thereiiito. as bel`ore the :tir entering ciianiber ST b v way of pipes .lt) and Ul. ln this connection. it niay be stated that the principal object ot' raisinpl the bealii bodily is to permit it to be eniphnxed for leveling' the coal in the ovens. as hereinafter de.- scribed.

vl"roui the foregoing, it will be apparent that through the niediuin of the various niecllalii;'nis above described. the benin c vliuder :nay be raised and lowered bodily, alid swung or rol-lied either to the right or left b v correspondinglv moving thc turntable. and may be tilted iii a vertical plane b'v operating: lever 233. 'llie operation of this level' also ett'ects the reciprocation ot the beanl. Hence it; is poasible to so adjust the beanl with reference to the oven that the shovel or other tool attached to the benin may reach. any desired pointl in the oven when the beani is in operation. ity will also be apparent that both controlling valves 3l and Il are actuated b v manipulating` handle 3?.

The niacliine as a whole is propelled along the track l b v the traction inceiianisnl ll. 'this mechanism. which is beat illustrated in li'ig. coniprisesa cylinder 103 pivotally supported at its rear end b v niealis of trunnions 10-l titting in a bearing bracket 105 The forward end of this cylinder may be adjustably supported by any preferred devices` such for inatance. as that shown in the above-mein tioned figure. In the present instance the front portion of the beain rests ill a yoke 160 suspended by means of a chain 1Q1 or similar device from one ariii ot an angle level' 162 pivoted ill a depending bracket 163 secured to the luider face. of the plat` forni. The other arni ot thi; lever is connected b v a rod 16J; to an operating lever 165 located adjacent the lever 119. Levers 165 and 119 project through slots formed iii said platform. Yitliin said cylinder works a piston 10G, the rod 10T of which is provided at its projecting outer end with a. grab hook 108 designed for successive engagement witll pins 10S) carried by brackets 11i) secured at proper intervals apart to theV track ties 111. the pins being arranged lonl gitudinally of the ties. The operating tluid is supplied from pipe 2G to a valve chest H2 inonntevhon cylinder 103 by way of a hose-pipe' lli-l, within which chest there is arranged a slide. valve 114 similar to the valves already described. This valve controls the exhaust passage 115 and inlet passages 11G and 117 formed in the bottom wall of the chest., and is connected by means of a rod 118 to an operating lever 119 pxvoted to a block 12) fastened to the traction cylinder. bcnncetion is had between the inlet passages 1113 and`117 and the -ends of the traction cylinder by means of pipes 121 and 122.

ln operating the traction mechanism to cti'ect a forward movement o1? the machine, lluid admitted through pipe 121 against the rear face of piston 10G sces to project Athe same outwardly until its hook is above the nearest pin 109. When such position is cached, the cylinder is lowered so n s to engage the hook with said pinI The fluid 1s then admitted upon the opposite side of the piston, thereby retractlng the. latter and consequently ceasing the machine to .advance along the track. The above operations are, of course, reversed when backward movement of the machine is desired. A definite relation existsV between the positions of the pins and ovens, as will be understood,l the machine being drawn into operative position when the piston reaches the limit of its inward movement. The traction mechanism is also operated to eliect a slight forward and backward movementof the machine adjacent the mont-ii of an oven, to enable' the shovel to reach various parts thereof.

rlfhe shovel which is employed in drawing the coke. is attached to the outer end of the beam. as shown ir. Figs. 6 to 10, wherein it is generally designated by the .letter K. It consists of a hea l123 formed with a passage in which the reduced terminal 121 of the beam tits, an upper jaw 125 rigidly secured to the head,` and a lower ]aw 126 pivotally connected to said head and having a furtif-er connection by means of a link 12'( with a sleeve 1.2.8 slidable upon the beam. The beam terminal 124 has the outer end portion thereofl threaded for engagement with a nut 129 which serves to retain the shovel or other tool in place. The upper jaw 125 is in the nature of a U-shaped skeleton frame, the front portieri of which is formed with a series of rearwardly and downwardly inclined teeth 130. The lower jaw 12G com prises an angularly oset' plate having a series of forwardly pro]ect1n 1 teeth 131 s ecured to its front or lower e ge, and a pair of relatively short guard or stop teeth 132. secured to its side edges above and parallel with teeth 131. Upon the upper surface' of the head and adjacent the rear end thereof, there is pivoted a trigger 133 having a n ose 134 which is arranged for normal reception isleeve 128 against 'Jaw and will in in a seat 135 formed in sleeve 128. The trigger is formed with an upwardly estending trip arm 136 which lies 1n the path of a tri) 137 pivoted to the forward'cnd of a rod 138 which in turn is 139 mounted upon the forward end of the beam cylinder and projecting beyond the saine. .Bar 139 carries a depending hano'cr 140 wherein is mounted one above the ot ier a pair of rollers 14-1 between which the beam slides and is supported. The teeth 1112, above referred to, serve to arrest the movement of the blocks of colte onto the shovel and hold said blocks in place thereon.

During the operation of the shovel. its

parts assume three positions which are ilins- 4 trated in Figs. 7, 8 and 9. In tion, the lower jaw of the shovel slides along the floor of the oven and is forced beneath the colte, the trigger 133 holdingy i movement. lVhen the shovel has been filled and is withdrawn from the oven, the friction of the lower jaw on the oven door will cause said jaw to swing slightly upward, thereby sliding sleeve 1.25 toward the shovel head, as shown in l `ig. S, such action tilting the trigger upward by the engagement ot' the beveled face of its nose with the beveled rear wall of seat 135. 'When the shovel has been completely withdrawn from the oven, its trip arm 136 will come into contact with trip 137, whereupon the trigger arm will be raised still higher, thns freeing sleeve 128, which will slide rcz'irwardly under the weight of the lower consequence discharge the load of col-:e on the ground in front of the oven. As the inward movement nears its limit, the sleeve will strike against bracket 140, and will be forced forwardly thereby nntil the trigger nose is rengaged in its seat, the trip 137 being swung upward on being struck b f arm 136 so as not to vinterfere with such rengagement.

The shovel above described may be rei moved bodily, if desired, and replaced by the scraper head K .shown in Fig. 13. This element comprises merely two parts, namely. an attaching sleeve 142, which lits on the beam terminal 121 and is held in place thereon by nut 129, and a blade 143. said blade being similar in shape to that' of an ordinary hoe. The scraper blade is designed to work upon the top of the calred mass of coke rather than beneath the same.

The scraper head is likewise replaceable by the leveling head K2 which is shown in Fig. 14 and is adapted for `ilse in levelingr the coal in the oven before it has been burned into coke. Like the scraper head, it is composed of a sleeve 144 and a depending plate 145, the latter part being formed at its lower edge with a lateral flange 146 which extends the entire length of said plate and projects upon both sides thereof,

thc first posisecurcd to a bar A ice The machine finally includes a water brake which acts in conjunction with the. hollow inner or supplemental piston 12 arranged within the main' or beam cylinder l and is operated h v Water under pressure stored in tank S8. T o supply water to said piston there is provided a pipe 147 arranged adjacent to pipe 22, (see Figs. 4 and 4a) one end of this pipe opening directly into piston rod 14 While the other end is connected by a short hose pipe 145 with the upper end of pipe 90. Pipe 14"?, adjacent its outer end, is provided with a bypa 149 having a valve 150 arranged therein, there being also a controlling valve 151 and a drain or relief valve 152 arranged in pipe 147 to the left of the by-pass, and a check valve 153 arranged in said pipe between the arms of the by-pass. The check valve is adapted to open when Water is supplied to piston rod 1i and to close when such supply is completed, thus causing the Water on exhausting, to return to the tank by Way of the by-pass, the passage of the water therethrough beiner controlled by the valve 150. On being admitted into the inner piston, the water will flow through the opening in the head 1G and will fill that portion of the hollow outer piston rod 13 to the left of the head. The incoming water may, if desired, be utilized to project the main piston, (2'. e. the beam) outwardly of its cylinder, and this is pref crably the case when the scraper head is in use, since that tool must be placed with considerable nicety upon the top of the coke. The main function of this water, however, is to act as a brake for the inward or return movement of the beam by checking the rapidity of such movement when effected by air or steam, the Water flowing through the lay-pass during its return to the tank, the rapidity of such flow being controlled by valve 150, as above stated. There is also included in the supply pipe 17 a luy-pass ll provided with a controlling valve 155, said pipe 17 being further provided with controlling and relief valves 156 and 157, and

with a check-valve 158, the last-mentioned valve being arranged between the arms of by-pass 154. This by-pass is active only during the exhaust movement of the actuating fluid which is directed therethrough by the action of the check-valve 158, which valve acts in the same manner as the valve 150 in the water lay-pass 149. Vhen Water pressure is notV utilized. and the beam is actuated solely by air, the controlling valve 151 is closed. and at the same time the relief valve 152 is opened to prevent back pressure of the air caused by the inner piston head 1G. On the other hand, when the outward movement of the beam is effected h v hydraulic pressure, valve 156 is closed and valve 157 opened.

The operation cf the machine as a whole is thought to be apparent. from the foregoing, and further description thereof is accordingly omitted.
