HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 419,279, dated January 14, 1890.

Application filed February 15, 1889. Serial No. 2991 (N modem To all whom it may concern.-

Be it known that I, PHILIP A. MYERS, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Improvement in Hay-Carriers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is a combined hay sling and carrier, and relates to that class in which the carrier is moved upon a track to the position of the hay to be elevated, and after its elevation the carrier is again moved along its track to the place of deposit in the barn or other structure.

In carrying out my invention I have in view three principal objects: First, to provide a carrier adapted to carry heavy as well as light loads; second, to provide a construction by which the load of hay is elevated through an interposed winding-drum, so that less power is required than in ordinary forms of carriers in which the load is lifted by a direct hitch, and thirdly, in holding the load in its elevated position during its transit along the track without applying a grip or other pressure directly upon the hoisting-rope.

My object, further, is to generally improve the efficiency of the carrier, the elevating apparatus therefor, and the details of construction connected with the manipulation of the carrier. 1

In the accompanying drawings, Figure 1 represents a pers'pectiveview, of my invention. Figs. 2 and3 are details. Fig. .4 is a 5 plan view. Fig. 5 is a side elevation of the carrier opposite to that side shown in Fig. 1.

In the drawings the track is shown at a, and may be of wood or metal, and while I prefer to use a track composed ofv two sections held together by clamps, it will be understood that any other kind of track may be used instead. The frame A consists of a long 7 beam suspended beneath the track by trucks B B, one supporting each end of the frame, and each provided with four wheels, so as to give ample support to the frame and enable the carrier to be used with very heavy loads. The wheels shown on the trucks are adapted to the form of track shown; but the arrangement of the wheels may be changed in case another kind of track is used. The trucks are composed of sides 1, of open frame-work cast purpose of allowing the bolt, or rather the ring 2, to oscillate slightly longitudinally of I the carrier as the wheels of the truck pass over any inequalities in the track, the slots 3 serving the same purpose as if an enlarged opening were formed around the bolt 5, and slight lateral movement is also allowed by the cross-slot 4L and the lug 7 projecting in the said slot, the under face of the ring 2 being made slightly convex to allow thispivotal movement.

The hoisting-drum is shown at O, and is supported upon an extension of the frame A directly beneath one of the trucks, and this truck, having four wheels, will carry the load equally, while the other truck sustains the greater part of the load which is being elevated and carried. A horizontal beam b is supported beneath the beam A, atone end thereof, by a bolt, which not only serves to support the beam 6, but also has a pivot for the winding-drum which rotates around it. The opposite end of the beam b is supported by a vertical post 0, which connects it with the beam A.

The reel or winding drum is preferably composed of wooden arms, one set being of greater diameter than the other, the upper set being of lessrand the lower set of the greatest diameter, the arms of each set being, made integral and each double arm radiating from the hub of the winding-drum, which consists of upper and lower flanged plates de, between which the arms are clamped by suit-. able rods with nuts upon their ends. The arms of the reel are shown at f, and consist of a bifurcated lower part andan upper part of less diameter having an overlapping tongue 10, which thus provides a double winding-v drum, upon the lower and larger part of which the rope which rotates thedrum is se-.

cured, and to the upper or small part of which the rope which hoists the load is secured, thus providing great leverage, on account of the difference in the size of the drum for hoisting the load. It will be understood,however, that instead of making the arms of wood they may be made of metal, and instead of being in one piece each reel may be made separate and the two secured together in any suitable way. I shield the rotating drum by means of a guard 11, which encircles the drum for about two-thirds of its circumference. The drum may also be arranged vertically, if desired.

During the hoisting of the load it is necessary that the carrier be held from movement along the track while power is being applied to rotate the drum, and I have provided for this by securing to the track, at the point where the load is to be raised, a block 7L, having inclined sides and a central slot or opening 11, and on the carrier, directly in line with this opening when the carrier is in po sition beneath it, I provide a pin 7?, which passes through the beam 1) and also the beam A, having a washer held by a suitable pin to form a bearing for one end of a coiled spring 7c, while the other end of the spring bears against the proj eeting end of the beam 1), thus placing the pin '5 under compression, which has the tendency to force the said pin constantly upward, and as soon as the carrier reaches the incline of the block the pin is depressed until it reaches the opening in the center of the block, when the spring again acts and the pin is forced into the opening, and thereby prevents the carrier from further movement on the track until it is released by depressing the pin and freeing it from its engagement with the slot. I perform this operation automatically by a pivoted 1ever 12, depending from astud 13, secured to the beam A, one end of said lever being pivoted to the pin 2', while to the other end of said lever is pivoted an arm 14, which carrics a ring 15, through which the hoistingrope passes to the load to be lifted.

A supporting-block of ordinary construction I have shown at 16,0ne side of this block being in line with the opening in the ring 15, so that the hoisting-cord is in line with said opening. \Vhen the load has been connected, whether by means of a sling or a support, to to the hook of the hoisting-rope, the operatand pull upon said rope rotates the windingdrum, and as this is rotated the load is lifted, the hoisting rope being wound upon the smaller drum. During this time the carrier is stationary, by reason of the pin t being in engagement with the opening in the block 71; but when the load reaches the ring 15 continued movement lifts the said ring, and this, through its arm ll, elevates the end of the lever 12, and this depresses the pin. 1 against the tension of its spring, and any further pull upon the operating-rope Z will draw the carrier along the track. As soon as the carrier ing-rope Z is connected to a source of power,

is moved along the track it is desirable that the winding-drum shall cease to rotate, and I have provided means by which, as soon as the carrier begins to move from its stationary position, the reel or drum will be automatically locked and prevented from rotating. These means consist of a pin 17, identical with pin 2 arranged alongside of the pin 1', but having an elongated staple-extension 18 on its lower end extending beneath the beam 1), the short arm passing up through an opening in said beam directly in the path of the reel-arm. The pin 17 hasits end passing through the beam A, and this end is normally in its highest position, with its projecting end 19 also in its highest position and in the path of the reel-arm, so that while in this position the operating-rope I may be drawn upon to any extent to move the carrier longitudinally'without turning the reel or drum.

In order to allow for the raising of the hoisting-rope while the pin 17 is in a raised position, should the slings become entangled in the bundle that has been dropped on the full mow, I provide inclines 20 between each pair of reel-arms, so that as the reel is rotated to raise the hoisting-rope the inclines depress the end 19 against the pressure of its spring and allow the reel-arms to slip by. In order, however, to allow for the free revolution of the drum during the hoisting operation, the block h on the side opposite the opening 11 has a straight portion 22,but no central opening or slot, so that when the carrier has been moved into position ready for a new load the pin 1' engages with the opening 11, while the pin 17 is depressed by contact with the level portion 22 of the block, and the reel is then free to rotate under the action of the operating-rope. The shield or guard ll also serves to direct and guide the power-rope Z and to keep itin engagement with the drum. It consists, as shown, of a section of bar-iron secured at one end to the post 0 approximately in line with the upper part of the winding: drum an d extends around on this line to about two-thirds of the periphery of the drum. It is then bent in the form of a loop and runs for a short distance on a line with the lower part of the winding-drum to a point beyond the line of the central beam A, and at this point it is bent upwardly to contract thepassage between it and the upper member of the guard, and from thence extends parallel to the upper member for about a third of the circumference of the reel, and is then bent downwardly again on a line with the lower part of the reel to the post 0, where it is socured.

lVhen the carrier is used in one direction, the power-rope is passed from its reelbetween the members of the guard, and as the upper and lower members are on a line with the up per and lower portions of the reel or drum it will be seen that the rope is kept within the line of the channel in the reel-arms and prevented from any entanglement. In case the carrier is to be run in the opposite direction it is only necessary to place the pulley-block at the opposite end of the track and the power-rope can be passed through the contracted opening between the guard members to the opposite side of the winding-drum, and the parts of the guard at this point will serve the same purpose of directing the rope. In all other respects, also, the carrier is capable of movement in one direction or the other.
