HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 288,587, dated November 13, 1883.

Application filed July 29, 1882. (No model.)

Be it known that I, E. FLU'r MoRsE, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented a new and useful Hay- Carrier, of which the following is a specifica- My invention relates to improvements in machinery for handling hay; and the objects of my invention are to make a carrier which shall be capable of taking the hay from any place in a long barn or off a loaded wagon, raise it to the carrier, carry it forward along a track in the top of the barn, and at the place desired automatically drop the load and re turn to its original position, where it will let the fork down. and be ready to take another load; and to so construct it that the place from which the hay is taken, and also where it is dropped, can be easily and quickly changed. I attain these objects by the mechanism illustratedin the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a front view of myearrier. Fig. 4 is a back view of the same. Fig. 2is a front view of the movable buffer-car located over the place from which the hay is to be taken. Fig. 5 is a back view of thesame. Figs. 8 and 6 are views of the movable buffencar located at the place where the hay is tobe dropped. Fig. 7 is an end view of the carrier, and Figs. 8 and 9 are views of my fork attached to the carrier by a rope. Fig. 10 is an end view of movable bufl er car, Fig. 5. Fig. 11 is a seetional view of a part of the same on the line 1 2, Fig. 10. Figs. 12, 13, and 15 are detailed views of the carrier, and Figs. 14 and 18 are detailed views of the movable buifercars. Fig. 16 is a .view of the dead-sheave and its hanger placed at one end of the track, the driving-sheave being placed at the other end. Fig. 17 is a View of the coupling used to connect the ends of the rope that runs the carrier. Similar etters refer to similar parts through out the several views. I

The power necessary to run-the carrier is conveyed to it by the endless rope c e, which runs in the direction indicated by the arrows,

passing through the carrier, and being supported at the buffer-cars by sheaves Ii 71. The

supports Q Q to the track are made to pro ject below the track-rails, and are used in connection with clamps d to hold the movable buffer-cars in position. The clamp d, of which Fig. 14 is a plan view, is hung at one end on the frame, Fig. 5, by the pin that passes through and supports sheaves h. The other end of the clamp is provided with suitable places, d d, for receiving the ends of the supports Q, and is held in position by straps d connecting it to rock-shaft n, which rests in hangers proj eeting from the frame. About rock-shaft a is a spring adjusted so as to turn the arms of rock-shaft up and against the frame, when the arms a will have turned by the deadcenter and hold the clamp up securely. By pulling cord 4, which is attached to arm a of rock-shaft, the rock-shaft arms may be turned downward and the movable buffer unclamped and moved to any desired position. When the cord is released the spring about rock-shaf t it raises the clamp.

The buffer 0 is restrained from all but rec= tilinear sliding mot-ion by being paired with an open prismatic part of the frame, and is attached to an elliptic spring, 0, that rests in the frame. This springbuffer reverses the motion of the carrier and shifts some of its parts when the carrier strikes it.

The clamping mechanism of buffer-car Fig. 2 is the same as that of buffer-car Fig. 3 but the buffer P, which is to stop the carrier within a limited space, is held between two plates, P and P". The spiral spring P is restrained between the frame of the car and the plate 1?, and thus subjects the plate I? to the force of tion is caused between the plates and the leaf fer to stop the carrier by forcing the buffer through the car the desired distance. The buffer must be restored to its former position and be ready to receive the carrier when it returns. To attain this the plates 1? and I? have a small movement with the buffer,wliiich causes the plates to press the buffer whilebeing pushed backward, and to release it while being pulled forward. When the buffer is forward, the plates 1? and P are also forward,

the spring P, by virtue of which enough frictached.

the sheave'f .7-

The spring-catch l? is fastened to the lower side of buffer P and springs into a notch in plate P When the buffer is forced back, this catch causes the lower plate to move back and up the inclines, raising the upper plate off projections 1?, thus subjecting the buffer to the force of spring P. The movement of the lower and upper plates is arrested by suit-.

able stops. As the buffer is pressed still further backward the catch springs out of the notch, and the friction between the buffer and plates retains the lower plate at the top of the inclines, where the inclines are made nearly flat, so that the plate has little tendency to move down. However, if the buffer be drawn forward gently, the plates move forward with it and down the inclines, allowing the upper plate to again drop onto the projections P when the buffer will lie loosely between the plates, and, finally, when the buffer is returned the catch springs into its notch. The buffer is drawn forward by the carrier, which is attached to it by catch m The sheaves a b c c and drum G are hung in the frame of the carrier, and while sheaves c and are loose the sheaves a b and drum G are rigidly attached to their respective shafts. The loose sheaves c and c are so placed as to cause the rope c to embrace a considerable portion of the circumference of sheaves a and B, and thus transmit its motion to them.

Gear-wheel 7.: is rigidly attached to shaft h and meshes into pinion Z, which is loose on shaft 2', being restrained longitudinally by the bearing on the one side and a collar on the shaft on the other. Clutch m is made to turn with shaft 11 by key '11, but may slide longitudinally, and thus engage the clutch in the face of pinion Z.

Clutch m is operated by elbow m, which is hung to arms m projecting from the carrierframe. Casting Z is hung on arms Z", projecting from the buffer-car frame, and lever'm which is bolted to it, has one end connected by straps i to elbow-levert'flwhich is hung on the frame at i", and to which the cord 5 is at- Glutch m is thrown in by lever m", being forced against the lower arm of elbow m. Lever m" is thrown back by spring Z.

One end of rope f, to which the fork is attached, is fastened to the drum G, and is made to wind evenly by sheave j, which is hung in Thesheave-frame is pivoted to straps j, which are pivoted to the frame at The end of sheave frame j is provided with catches j, that hook over the lower part of the carrier-frame, and prevent the sheave from turning up about center j". For the purpose of unhooking, the sheave-frame has a small movement about the pivotspassing through it and straps 7' This movement is limited by stopsj. The lower part, 7' of the sheave-frame-proj ects inwardly over the sides of the sheave j, Figs. 7 and 13, and curves downward and outward, so as to guide ropef onto sheave j. r

. Lever a,whieh is pivoted to the frame at 9", has a catch adapted to engage with lugs b b on sheave b. It is also providedwithacurved arm, 4, adapted to strike the upper arm of elbow m, and thus disengage clutch m.

Lever s,which is hung on sheave-frame], is provided with two branches extending along the sides of the lower part, 7' of the sheaveframe, and adapted to strike and press down ring '0, encircling fork-head w, for the purpose of tripping the fork. Lever s also has an arm extending backward, to which chain sis at-' tached. Said chain passes over a sheave hung on strap j and another at j", and is attached to the lower arm of lever a.

Shifting-straps a and a are pivoted to lever to, and pass through suit-able guides at the ends of the frame, and are of such length that one or the other must extend beyond the frame enough to shift lever a the desired amount.

Oatchmis pivoted to buffer P, and is adapted to engage with lug t on the carrier-frame,

Releasing-bar f is pivoted to arm f,which is a part of or attached to one of straps j and passes through a guide in lug t, Fig. 12, so as to release catch m when strap j swings up about j Ratchet-lever s", which is hung to the frame, is adapted to engage ratchet-wheel 9 which is apart of or made fast to drum G. The upper end of ratchet-lever is connected to the frame by spring g,which keeps the lower end in contactwith ratchet-wheel 9 Rod t,whichpasses through aloop at the end of the frame, is also connected to the upper portion of ratchet-lever s", and is made to extend beyond the frame, so that ratchet-lever s will release drum G when the carrier strikes buffer P.

The straps an of the fork are pivoted to the IIO ears on the head w, and to the end of these straps the fork-tines are hinged. The catches ac, p-ivotedbetween the straps a at about their middle point, are adapted to receive the ends 00 of the fork-tines and hold them fixed relatively to straps to. The catches a" are thrown toward the tines by springs as, and are limited in this movement by stops as, Fig. 9.

The chains a are attached to the free ends of catches m, and pass over small sheaves between the straps near head 10, and are attached tothelowerends of arms'w,which project down ward from and are attached to ring 1;, so that when ring 1/ is pressed downward the tines are released from catches a.

The operation of my carrier is as follows: The rope e 0 passes over sheaves located at each end of the track, which may be of any desired length, and is driven in the direction indicated by the arrows. The rope is supbeing side by side, as shown in Fig. 7.

ported at the buffer-cars by the sheaves h h, and in going through the carrier passes over sheave 0, under sheave a, and over sheave c, Fig. 1, in the one direction, and under sheave c, then over sheave b, and under sheave c,

Fig. 4, in the other, the two sheaves c c and 0 y pulling cord 4t the buffer-car Fig. 2 may be unlocked and moved along the track until it comes under the supports nearest over the place from which the loads are to be taken.

Then, if the cord is released, the spring raises the clamp and locks the car. Buffer-car Fig. 3 may be unlocked and moved to the place where the hay is to be dropped, and locked in the same manner. The carrier is then run by rope e to buffer'car Fig. 2, the catch m drops into its place over releasing-bar f, as shown in the lower view of Fig. 12, the shifting-strap a" and rod t are thrown back, releasing sheave b and drum G, thus allowing the fork, from its own weight, to run down. At the same time the sheave-framedrops to the position shown in Fig. 1, and the releasingbar f 2 to the position shown in the upper view, Fig. 12. WVhen the load is secured in the usual manner, the cord 5'is pulled and lever m thrustagainst elbow m, thus throwing clutch m into gear and causing pinion Z to revolve with sheave a, which causes drum G to revolve' in the opposite direction and elevate the load. When fork-head w strikes the sheave frame, the sheave frame is unhooked and raised until straps meet the stops f, Fig. 4, projecting from the inside of the carrier-frame, the releasing-rod f raises catch m, and,the drum G and sheave a having now stopped revolving, the rope 6 draws the carrier ahead until it strikes the buffer o,which stops and starts the carrier in the other direction with the force of the spring 0. The forkis prevented from running down by ratchet-lever s",which is thrown in as soon as the carrier leaves buffer P. When the carrier strikes buffer 0, the strap aflwhich projected beyond the frame, is thrown back and imparts its motion to lever a and strap a, which is thrown so as to project beyond the CELIIIGI f1"dll16. The arm 9'' strikes the upper end of elbow m and throws clutch on out, thus allowing sheave a to run freely. The motion of elbow m is limited by stop 0', Fig. 15, projecting from the frame. The forked end of lever s is thrown down by chain 8 and forces down ring a, which, by chains a, releases the catches a, and the load throws the tines out and drops. The catch on the upper end of lever a catches one of lugs b b and stops sheave I), thus causing the. rope e, passing over it, to run the carrier back until it strikes buffer 1?, when shifting-strap a is thrownback,

which throws lever a back and releases and allows sheave b to run freely. The catch at" now drops into itsplace and holds the carrier securely to the buffer-car. The rod tis thrown back, and, drum G being released ,the fork runs y, substantially as and-for the carrier strikes buffer 1?, it moves the buffer backward, causing it to be pressed between plates I and Pin the manner described; and when the carrier elevates the load it draws the buffer, which moves freely forward in its effort to move ahead. The motion of buffer 1? is "limited by stops P It may be remarked that instead of gears Z and k, sprocket-wheels and link-belting can be used; also, instead of lever a being provided with a catch, one of the straps a or a can be extended upward and provided with a suitable catch, and that lug t can be put between the sides of the frame, instead of at one side; also, that my carrier may be used for carrying other substances than hay.
