HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 600,949, dated March 22, 1898..

Application filed June 24, 1897. Serial No. 642,028. (No model.)

To all whom it may concern:

Beitknown that I,NoRMANIsAoHsoN,acti zen of the United States, residing at Marion, in the county of Cassia and State of Idaho, have invented certain new4 and useful Improvements in Hay-Carriers, of which the following is a specication, reference being had therein to the accompanying drawings.

My invention relates to improvements in hay-carriers of that class known as sheaveframe catch, in which the sheave-frame on reaching the limit of its upward movement disengages the carrier from a stop on the way and also operates a retaining device to prevent the sheave-frame from descending.

The objects of the invention are to provide a stop which is always in the right position, even if the cable or way twistsand which can be readily removed and replaced; to provide an extremely simple form of catch-lever for engaging the stop which is adapted to reduce the wear of the parts to a minimum andV to insure their more perfect working and also to provide for the taking up of any wear upon the parts, and, lastly, to provide an extremely simple catch for the sheave-frame which while holding it securely will permit it to swing without danger of twisting the head of the sheave-frame.

The invention is illustrated in the acconr,

panying drawings, in which- Figure lis a side elevation of the carrier in place upon the way, parts being broken away; and Fig. 2 is an end view, the upper portion of one of the lower rollers 7 being broken off. Figs. 3, 4, 5, 6, and7 are views of modications.

In the drawings, the numeral 3 designates the wire or cable way upon which the carrier is designed to run. The way carries a stop 4, having a cone-shaped head 2, with the narrow neck in rear providing an annular shoulder 4b, which is adapted to be engaged by the catch-lever of the carrier to retain the'carrier against movement while'the load is being ele* vated. The stop is made in two parts, as shown, each part being provided with a longitudinal groove to receive a portion of the cable or way, so that when the parts are placed together the cable is securely clamped between them. Suitable means are provided for fastening the two parts together-such, for instance, as the setscrew 4.

The carrier consists of a double frame 5, substantially rectangular in shape, carrying rollers 6 at its upper side, adapted to run upon the cable, and rollers 7 at is lower corners, over which the hoisting-rope passes.

The catch-lever 8 is pivoted between the two parts of the carrier at 8 and has a hooked end 9. A roller 9a is provided on this hooked end, which is adapted to rest behind the annular shoulder on the stop, the shoulder being slightly undercut for this purpose. It will thus be seen that when the catch-lever is operated to release the carrier the roller rides easilyl off from the shoulder without wear on the parts. A second roller is pivoted in a recess in this arm to the rear of the hooked end, which is adapted to ride upon the incline face of the stop and thus relieve the lever from contact with said stop. The forward end of thelever passes across the slotted portion 5L of the carrier-frame, into which the T-shaped head 10' of the sheaveframe rises at the limit of the upward movement of the load, so that this T-shaped head lifts the end of the catchlever to release the carrier from the stop. The continual contact of the sheave-frame with the end of the lever is apt to wear the parts, so that in time the lever would not be lifted far enough to disengage it from the stop. To proat 13, consisting of two plates 13a 13b, each` having a hooked lower end adapted to engage one of the arms of the Tshaped head of the sheave. These plates are connected so that they turn together and are provided with portions overhanging the hooked portions, against which the head strikes as it approaches, so that the plate is rocked to draw the hooks up under the head l0. The springpressed arm 14 bears against the upper side of the retaining-plates and drops over a shoulder l5 when the head is in place within the recesses, so that it is held securely against downward movement. This arm is prefer IOO ably narrower than the space between the plates of the retaining device and is provided with a transverse pivot carrying antifrictionrollers 14:, which engage the shoulders of the retaining device. The sheave-frame is also of less thickness than the retaining device, so that when the head is held thereby the upper portion of the sheave-frame can swing freely back and forth to accommodate itself to the swinging of the load or when the load drags upon the top of a stack which has been piled up nearly to the table, so that there is no danger of bending or breaking the head.

I prefer to connect the two plates of the retaining device so that they will move simultaneously by forming the pivot pin with squared portions engaging correspondingly square openings in the plates.

As shown in Fig. 3, I may employ a modified form of sheave and sheave-frame which is provided with a clutch for positively locking the draft-rope when the frame is engaged and supported by the carrier. The frame h herein shown carries three sheaves d, d', and d2 and is provided with a hook, to which one end of the hay-sling is attached. The other end of the sling is attached to a second frame carrying twoV sheaves, over which the draftrope passes, as shown.

The T-shaped head d has a shank having its lower end bifurcated to form arms e, which are pivotally connected to the outside frame at a point between the sheaves a d'. A jaw g, having a curved face, projects up from between the arms e at the junction of the same with the shank of the head, and when the head is held by the carrier the weight of the load will press said jaw into engagement with the draft-rope, passing over the sheave a and positively clamp the same. By using the three sheaves and threading the rope, as shown in Fig. 3, both of the pulleys will be elevated evenly and thus prevent the load from turning up edgewise, so that when it is tripped it will spread out evenly over the stack. The weight of the load will also regulate the compression of the same. Thus by using a short sling and a long slack rope the bundle will be compressed as long as the weight thereof will effect it.

In order to move the load laterally or longitudinally in relation to the carrier without twisting the ropes, I have modified the construction of the carrier, as shown in Figs. 4: and 6, in which the pulley m is arranged at right angles to the carrier, being journaled in brackets depending from and supported by the bolts upon which the upper rollers are journaled. Upon the opposite side of the carrier and pivotally supported in similar brackets is a sheave-frame y, in which the sheave n is mounted. The trunnions of this frame are placed slightly above the central line thereof, as shown in the detail View, to effect an easier operation of the same. The sheave-frame has in this form the T-head arranged parallel with the sides thereof, and

thus the sheaves are arranged transversely in relation to the carrier.

Having thus described my invention, what I claim isl.v In combination the way, the stop having an undercut flange, the carrier and the catchlever havin g a roller adapted to rest against `said undercut iiange, substantially as described.
