HAY-CARRIER.

To all whom it may concern.-

' Be it known that I, lnimr A. Mums, a

citizen of the United States, residing at Ajshland, in the county of Ashland and State of Ohio, have invented certain new and useful 'Improvements in' Hay-Carriers, of which the following is a specification, reference being had therein to the accompanying drawing.

'lhis invention relates to hay carriers and the objectof the invention is to provide a carrier having means to automatically lock the hoisting rope,-t-o hold the load against. downward nmveme nt, when the tension on the-hoisting rope is relieved, as when the team stops and backs.

To this end it is a further object to pro- .vide guides or sheaves about which the hoisting rope passes, which have bodily move ment relatlvelyto the supporting frame and which are so connected with the rope lock that when one of said sheaves is subjected to a stronger pull than the other, the rope lock will be moved into its operative position, and, when the last-mentioned sheave is subjeeted to a pull greater than that to which the first-mentiontal sheave is subjected, the rope lock will be moved into its inoperative position.

It is also an object of the invention to provide means for retaining therope lock in either its operative or inoperative position until positive force has been applied thereto.

It is a further object of the invention to provide a hay carrier in which the hoisting rope will serve not only to hoist the load but also to control the operation of the rope lock, and in which the lateral movement is imparted to the carrier, to carry the load into the mow, by means other than the hoisting rope.

In the accompanying drawin s, Figure 1 is a perspective view of a hay carrier embodying my invention, showing the same in operative position upon the track; Fig. 2

is a vertical, sectional view taken longitudii nally to the track; 1g. 3 is a vertical. sectiona'l view, taken on the line a: a: of Fig. .2 and looking in the direction of the arrows; Fig. 4= is a vertical. sectional view, taken on the line y 3 of Fig.2 and looking in the direction ot the arrows; Fig: 5 is a detail view of the supporting lever for the two sheaves and. the means for retaining the Specification of Letters Patent.

sheaves in their adjusted posit-ions; Fig. 0 is a detail view of one of the arms carrying the shoe of the rope lock.

In these drawings, I have illustrated one embodiment of my invention and have shown the same as comprising a main frame 1 havit'ig an upper portion 2 consisting of two members spaced apart and carrying rollers 3' adapted to engage a track 4, which or webs 5 arranged parallel one to the'other and rigidly secured to but preferably formed separate from the upper fran'te members. The plates 5 are arranged near the center of and transversely to the frame members 2 whit-hextend longitudinally to the track. 'lhese plates or webs 5 constitute the supporting members upon which the several parts of the controlling mechanism of the (ill'l'ltl' Zll't lllUlllllttl.

main guide or sheave l iscarried by the supporting plates 5 and has both a rota r v movement and a bodily movement relatively to the supporting frame. in the construction here shown the sheave 3 is rotatably mounted on-a shaft 7, which, in turn, is journaled in the rear ends of two levers 8 arranged on the outer sides of the respective frame members 5 and pivotally mounted thereon between their ends. Preferably each lever is provided with a bearing aperture 9 which receives a trunnion 1t) projecting outward from the corresponding frame member .5. Those arms of the levers extending in the rear ofthe pivotal center thereof and in \vhielr'the shaft 7 of the sheave t' is journaled are. of less length than the forward arms ot' these levers, as is clearly shown in Fig. The forward arms of the levers 8, which are indicated by the reference numeral 1-], have their extreme forward ends turned upwardly to support a second guide or sheave 1:! which is mounted between the forward ends'of the two levers 8 on a shaft 13 mounted insaid-arn'is. It is apparent, therefore. that the main sheave (5 and the auxiliary sheave 12 are mounted on opposite sides of the axis of the two levers ts w-hich constitute a supporting device for these sheaves. Consetpiently, when one sheave moves downwardthe other must move upward.

rope guard, preferably U-shaped in cross section and indicated by the reference numeral 14, extends abontthe upper pormay be supported in the usual manner. The frame also comprises two depending plates tion of the smaller or auxiliary sheave 12 and preferably has its arms mounted on the shaft 13 between the opposite ends of the hub of the sheave 12 and the respective arms 11 of the levers 8. This rope guard has an upwardly extending pin or projection 15 which passes through an apertured lug 16 carried-by and preferably projecting forwardly from the main frame of the carrier. A suitable stop, such as a nut 17, is secured to the pin 15 and serves to limit the downward movement of the auxiliary sheave 12, and, consequently, the upward movement of the main sheave'G. By adjusting the stop or nut 17 on the pin the amount of this move ment can-be regulated. A rope guard 18 extends about the rearward portion of the main sheave (3 and is preferably carried by arms 19 extending rearwardly and downwardly from bell crank levers 20 mounted on the shaft 7 of the sheave 6 between the ends of the hub of that sheave and the cor- This rope is then carried through-the pulley blocks 25 to which the hay sling, or fork, is

' connected, thence upward over the sheave 6,

then forward over the sheave l2 and downward about suitable guides to the team or other source ofpower. The other arms of the bell crank lever, indicated at 26, ex-

- tend upwardly in sub'stantiallg vertical positions and have their upper en s apertured to receive trunnions 27 carried by a frame'28 which is provided at its forward end with other trunnions 29 journaled in bearings 30 'on opposite sides of the main frame.

A rope lock is provided to grip the hoist ing rope and lock the load against downward movement whenever the tension on the hoisting rope is relieved. To this end suitable connections are arranged between the two sheaves 6 and 12 and the rope lock, whereby, when the downward pull on the sheave 12 is greater than the pull on the sheave 6, as'when the team is hoisting the load, the rope lock will be moved into and maintained in its inoperative position. As soon as the team stops and permits the hoisting rope to slack off, to even a, very slight extent, the downward pull on the rear sheave 6 will exceed that on the forward sheave 12 and will causethe ro e lock to grip the hoisting rope and 'loc the load against downward movement. In the present construction the ropelock comprises a shoe 31- levers 32 and 33 arranged on opposite sides 1 of the sheave. These levers are pivotally mounted on the respective bell crank levers 20 at points forward of the axes-of those levers. The shoe may be connected to the levers and the levers mounted on the supporting levers in any suitable manner. As here shown this shoe is provided with a hollow bearing lug 34 adapted to receive inwardlyextending trunnions 35 carried by the levers 32 and 33. Each lever is also provided with a trunnion 36 adapted to enter a bearing aperture 37 in the respective bell crank lever 20. Preferably, these trunnions are secured in their bearings'by means of pins 38 extending through the'trunnion and through washers arranged on the opposite sides of the levers 20. Each bell crank lever, 32 and 33, has its forward arm of less length than its upwardly extending arm and also has its forward arm bifurcated, as indicated at 39. These bifurcated arms engage a transverse bolt 40 which extends through arms of the outer levers 8. One of thelevers carrying the shoe 31, here shown as the arm 33, is provided in its upper end with a lon gitudinal groove 42 formed by providing the inner face of the lever 33 with inwardly extending flanges. This lever is also provided with a rearwardly extending projection or arm 43 having its lower edge curved. The sheave 6 is provided on the side adjacent to the lever 33 with laterally extending projections or lugs 44 having their upper and lower surfaces converging rearwardly.

When the'rope lock is in its inoperative position the arm 33 will occupy such a posit-ion relatively to the sheave that the lower edge of the bottom flange of the groove 42 and the arm 43 will be out of the path of the projections on the sheave and the sheave will be free to rotate in either direction. Ifthe tension on the hoisting rope is relieved the weight of the load instantly exerts a downward pull on the sheave 6. This pull is transmitted through the shaft 7 to the levers 20 and tends to move these levers bodily downward. The downward movement of the sheave is also transmitted to the bell crank levers 8 and tends to rock these levers about their axes and elevate the forward ends thereof.

the load not only moves the sheave bodily The combined movements of the levers 20 and 8 cause the levers downward butalso rotates the same rearward. Cor \equently, the lug which enters the groove in the lever 33 will engage the lower edge thereof and tend to move the lever rea'rwardly and downwardly until the shoe is brought into engagement with the hoisting rope, and, when the slide is in engagement with the rope, the pull of theload on the sheave will cause the shoe to exert a continuous pressure on the rope, thus retaining the same against movement. Further, the engagement of the lug with the lower wall of the groove locks the sheave against Y, 1.5 l ,which cooperates with the shoe.

' load has been dumped or it is desired to conelevate the levers 20.

rearward rotation and -thus causes the sheave to constitute a fixed locking member, \Vhen a tinue the elevation of the road a forward pull on the hoisting rope will tend to move the auxiliary sheave 12 downward and thus rock the levers 8 about their axes and also This movement of the levers 8 and 20 rocks the levers and about their axes and moves the shoe of the rope lock out of engagement with the rope.

The? forward movement of the hoisting rope 'Will also rotate the sheave 6 in a forward direction, causing the adjacent lug to engage the under side of the curved arm 43. and force the-lever 33 upward to complete the movement of the rope lock into its inoperative position.

It is desirable that some means should be provided to hold the rope locking device either in its operative or its inoperative posit-ion until force has been applied thereto to shift its position. In the present instance this is accomplished by providing each lever {5 with an upwardly extendingarm 45 which is hollow and contains a coiled spring ll). The upper end of the hollow arm I?) is open and the lower end of a finger l7 extends into said hollow arm and engages the upper end of the spring therein. The finger l? is pivotally mounted on the side member of the-main frame at a point which lies between the lines of thearm 45 when the latter is in its foremost and rcarmost positions. that is, when the locking device is in its inoperative or operative position. Consequently, the pressure of the spring against. the end of the finger 47 will be greatest midway between the extremes of the movementof the arm 45. and, when the arm is on either side of its central position. the pressure of the spring on the linger l7 will tend to retain the finger in that position and hold the rope lock either in engagement with the rope or out of engagement therewith, as the case may be, until positive force has been applied thereto.

The hoisting rope 24, which serves not only to elevate the load but also to control the operation of the rope lock, is not used to move the carrier laterally to convey the load into the mow. This is preferablyaccomplished by separate means. In the present instance a rope 48 is connected to each side of the main frame, which is here shown as pro-. vided with aperturcd lugs 49 to receive these ropes. These ropes extend about suitable guides and thence downward to the team so that a pull on either rope48 will move the carrier along the track toward the respective side of the mow. Although the rope lock may be. readily controlled by the hoisting rope a separate trip rope may be provided for releasing the. lock if this is desired, and. in the present drawings, 1 have shown such a rope 50, connected to the forward end of one of the levers S and extending through a guide 51 carried by the-for-' ward end of the corresponding lever 20.

The operation of the device will be understood from the foregoing description of the several parts thereof and it will be apparent that the hoisting rope will be automatically locked against downward movement whenever the tension thereon is relieved and that the locking and releasing of the hoisting rope maybe controlled by the hoisting rope V fore. wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
