EDW'IN D. MEAD, OF SHORTS'VILLE, NE\V YORK.

HAY AND GRAIN ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 320,267, dated June 16, 1885.

Application filed April 23, 1885. (No model.)

To all whom it may concern:

Be it known that I, EDWIN D. MEAD, of Shortsville, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Hay and Grain Elevators and Carriers, of which the following is a specification.

My invention relates to hay and grain elevators, carriers, and unloaders, and more particularly to that class in which binding ropes or slings are used instead of forks, grapples, or like devices.

The present invention is designed as an improvement upon the apparatus for which Letters Iatent were granted me on the 2d day of December, 188i, numbered 308,621, and is designed to insure the proper and compact binding of the bundle, give increased power in elevating, and give the attendant perfect control of the apparatus, so that at any point of elevation the car may be started and the bundle discharged.

Figure 1 isa perspective view of my improved apparatus. Fig. 2 is a top plan view of the car with the carrying rollers and their arms broken away; Fig. 3, a longitudinal vertical section through the car; Fig. 4, a vertical transverse section through the same on the line a; a; of Figs. 1 and 2; Fig. 5, a sectional plan view of the hoisting-pulleys and their clutch mechanism; Figs. (5 and 7, elevations of the shirnpulley block with the side partially broken away; Fig. 8, a horizontal section of the same on the line 91y, Fig. 7; Fig. 9, a detail view of the clutching mechanism.

In the practical use of this class of devices it is found that there is a tendency to lift the load to the car or carrier before the binding ropes or slings are drawn tight, and when this happens the load is liable to escape from the sling and fall before reaching the desired point. This shirrpulley as commonly constructed has but a single rope, and the elevating devices do not afford sufficient power under all circumstances, and it is chiefly to overcome these difficulties that the present invention is designed. This construction will be readily understood upon referring to the annexed drawings, in which.

A indicates a car or carrier; B, a pulley block common] y called a shii'r-pulley block G, the hoisting-rope, and D the sling or bind ing-rope.

The car or frames, a a, connected by bolts and held apart by spacingbloeks, as usual, rollers I), applied to the arms 0 of the side frames, hoisting pulleys, a pivoted frame carrying the hoisting-pulleys, a lever connected with the pivoted-frame and arranged to act in the manner of a scale-beam, and a clutch mechanism connected with and operated by the last-mentioned lever to connect the hoisting-pulleys while binding the load, and to disconnect them when the load is bound and is being elevated. The construction and relation of these parts may be best seen in Figs. 2, 3, 4, and 5.

E indicates a frame, pivoted at or near one end to the car or carrier A by a cross-bolt, d, which serves also as an axle for a guidingpulley, F. The frame E carries a cross-bolt or rod, 6, which forms an axle for pulleys G and II, which pulleys are locked together while the binding rope or sling is being drawn tight about the load, but are separated and allowed to rotate independently when the load is being lifted, for which purpose said pulleys G H are formed with teeth f, on their oppos ing faces, as best shown in Figs. 4 and 5.

I indicates a lever or beam, advisably furnished with an adjustable weight, g, and pivoted near one end in framec a, as shown in Figs. 2 and 3, the weight being applied to the long arm of the lever, and. the shorter arm thereof being connected by a link, h, to the free end of the frame E, which carries the pulleys G H. Under this arrangement, and owing to the great leverage it affords, the weight g, or the lever I itself, if the weight be omitted, serves to lift up the free end of the frame E and to hold it up against a heavy weight or force applied near the pivot of said frame. The pulleys G- H are located near the pivot d of the frame E, and carry the hoisting-rope c, which drawing down upon the pulleys G H their frame E must overcome weight g and lever I with all their advantage in leverage. It will thus be seen that before the lever I can be lifted a predetermined and very considerable resistance must be offered by the load to the hoisting or elevating power.

Lever I is connected by a link, J, with a shifting-lever, K, hung or pivoted on the axle c beside pulley G, which latter pulley is capable of being moved along the axle c to or from pulley H, which latter is free to rotate on said axle, but has no sliding movement thereon.

consists of two parallel slideplates V The shifting-lever K consists simply of an arm perforated to fit the axle e, and provided with inclined lugs t on its outer face to ride upon the two pulleys must move together as one double pulley.

When the load placed upon the hoistingrope overcomes the leverage of frame E and beam or lever I, together with weight y, if used, the shifting-lever is actuated in the reverse direction, the inclines 'Z and j ride back, allow the lever and the pulley G to be thrown outward by the inclined faces of the teeth f acting together with the guide-pulley, which sets to one side of the line of draft, and thus the pulleys G and H are disconnected. Thus, it will be seen, the pulleys G and H are automatically locked together until the load or resistance reaches a certain predetermined point, at which point they are automatically unelutched and allowed to rotate independently. The object and importance of this construction will appear farther on.

As shown in Figs. 2, at, and 5, the pulleys G H are each made with a V-groove, and the sides of the grooves are ribbed, this form being adopted to prevent the hoisting-rope from slipping on the pulleys. To still further guard against such slipping,thepulley F is provided with ribs and made of like form, the hoistingrope being carried beneath said pulley and thereby made to. wrap or be wound about the pulley G farther and more closely than if carried directly to the guiding-pulley F,and said pulleys G and F being provided with intermeshing teeth, so that the rope cannot slip unless it loses its holdon both pulleys at the same time.

To permit the draft-rope, which is merely a continuation of hoisting-rope O, to be carried beneath the car A toward either end of the track without interfering with the vertical rope, the guidepulley L is placed at one side of the frame, as shown in Figs. 1 and 2.

M indicates a vertically-sliding frame or yoke the side bars of which are seated and move in grooves or guides kin the side frames, at a,of the car. The top bar or cross-piece of the yoke projects over and rests upon the side frames, a a, when at its lowest point. The lower end of the yoke M is furnished with an inwardly-turned arm, Z, having a hole or eye, m, through which passes a rod, N, pivoted at one end in the car A. To the free end of the rod N is attached a cord or rope, O, which U passes over a pulley, n, in the beam or lever I, and descends then to the floor of the barn or other structure in which the car is used,

When the rope is pulled, it raises rod N and with it the yoke or frame M, and the same elevation of the yoke or frame will occur whenever the pulley-block B is drawn up against its lower end. The purpose of this yoke is to raise the pivoted hooks P, which are applied to the sides of the track-beam or rail Q, and engage over blocks or lugs 0 formed upon the arms 0, as indicated by dotted lines in Fig. 1, to hold the car stationary while the load is being elevated. The hooks have their free ends bent upward, and are limited as to their descent, so that the lugs 0 ride freely under and lift them when the car comes to its leading pe sition. The hooks have their free ends turned in opposite directions, so as to lock the car against movement in either direction.

Referring now to Figs. 1, 6, 7, and 8, the construction of the pulley-block B will be explained. As sh own in several figures, this block is formed with a metal body or shell,p,the lower end ofwhich is fashioned into anose or horn, q, and provided with a spring lat-eh or hook, r. This construction is for the purpose of per' mitting the rings or eyes 8 of the compressing rope or sling D to he slipped over or upon the horn and held there by thelatch or hook r until the latter is tripped or withdrawn, as is now done with other devices of similar construction. The other end of the sling or compressing rope D is attached to the hoistingrope O, which passes up through the pulley block B to the car A.

R and S indicate two pulleys, mounted upon a bolt or axle, t, passing transversely through the shell or bodyp, as shown in Figs. 1 and 8. These pulleys are formed with teeth at on their opposing side faces, and adapted to be locked together or thrown apart in the same manner as the pulleys G H of the car A, and a shiftinglever, T, provided with inclines v to ride'upon inclines w of the shell 1), is mounted upon the axle t, as with said pulleys G H. When the shifting-lever T is lowered, the inclines crowd pulley R over against pulley S, causing their teeth u to interlock and the two pulleys to turn together as one double pulley; but when it is raised the pulleys are permitted to separate and to rotate independently.

A push-bar, U, is jointed or attached to the outer end of shifting-lever T, and is also connected by a link, x, with the shell or body P of pulley-block B, in position to be struck and moved by the load when drawn up to the pulley-block, and as the load is only drawn against the push-bar as the binding or compressing is completed it follows that the pulleys will remain locked together during the binding operation and until the moment the hoisting begins.

The hoisting-rope, to which is attached one end of the compressingrope, passesinto pulicy-block B below, goes up behind pulley S, thence through the upper end of the block to pulley H of the car, over said pulley and down to pulley R of the block 13, thence up to and over pulley G of the car, thence under pulley F and over pulley L to the pulley at the end of the track, and thence to the ground-pulley, beneath which the rope usually passes before reaching the horse.

V indicates a swinging or pivoted frame pivoted in the block B, and carrying a roller, y, at its forward or center side, behind which roller the sling or the draft-rope passes as the load is bound or compressed, the rope thus exerting an outward pressure upon the roll and tending to rock or tip said frame outward. The upper end of the frame is furnished with teeth 2, which mesh with similar teeth 2 on the pulley B when the frame is tipped slightly forward, and it is further formed with a dog or nose, (1, which is shaped to enter the groove of pulley R and to bear against the rope therein. Vhen the rope is being drawn up through the pulley-block B, the pul ley It rotates in such direction that it tends to throw the frame V inward and hold dog a away from the rope; but whenever the rope begins to descend it turns pulley It in the opposite direction and tends to swing frame V outward and to bring the nose or dog a against the rope, thereby locking the same against accidental or premature descent.

The frame D carries at its inner sidea roller, 0, over which passes a cord or rope, (1, one end of which is attached to the spring-latch r. The other end after passing over roller 0 drops to the floor or ground, where it may be reached by the attendant. By drawing up the rope or cord (1 the latch r is tipped or withdrawn, thereby allowing the eyes or rings 8 of the sling to escape from the horn q of the pulleyblock B, and the frame V is swung inward upon its pivot and caused to release the hoisting or binding rope, which will allow the block I; to descend.

The apparatus being thus constructed, it is operated as follows: The block B is suspended from the car A by the hoisting-rope, the sling or binding-rope D being drawn down through the block. A sling or binding-rope is laid lengthwise of the wagon and a quantity of hay or grain placed thereupon, a second rope and another bundle or layer of grain, and so 011 until the wagon is loaded. When it is de sired to remove a load or layer from the wagon, the shirrpulley block is drawn down and the ring or rings 8, at opposite ends of the top sling or rope, are slipped upon the horn q to a point above trip or latch r. A horse is hitched to the draft-rope, which, as before stated, is a continuation of the hoisting-rope, and said rope running around pulleys L, F, and G draws upward on the hoisting-rope, which passes around pulley R of block B, back over pulley H of car A, and finally down through block B, and behind pulley S thereof, to the binding rope or sling, which is thus caused to draw firmly around the load and to bind it tight. \Vhile this is being done the pulleys G H of the car and the pulleys R S of the block are locked together, as explained, and thus the hoisting-rope is caused to pass up on one side and down on the other equally, and hence no lifting action is exerted on the block. \Vhen, however, the load is firmly drawn up or bound by the sling D, the load acts against push-bar, moves shifting lever T, and permits the pulleys It S to sepa rate, and as the sling and hoisting-rope can move no farther through the block the latter begins to rise. As the weight of the load thus comes upon the pulleys G H and their supporting-frame E, the movable end of said frame is depressed, thereby throwing up the weighted end of beam or lever I and rocking the shiftinglever K, which permits the pulleys G If to unlock and to rotate separately, thus giving the greater power of two independent pulleys acting in connection with the third pulley, It, of block B, and giving ample power for hoisting the load. hen the block B is raised close to the car, it strikes and raises the yoke M, lifts the hooks P, and allows the car to be drawn to the required point. \Vhen. there, the cord or rope d is pulled by the attendant below, thelatch r is withdrawn, the rings 8 are permitted to escape from horn q, and thus the load is discharged. The beam or lever I and the push-bar then fall by gravity and cause the pulleys G H of the car and the pulley s R S of the block to lock together in pairs, as mentioned, the draft-rope and the car are carried back, and the block descends for a fresh load.

The beam I and sliding yoke M, with red N, may be furnished with a shifting rope or bar by which to depress beam I, actuate the shifting-lever, K, and raise yoke M; or the frame E and lever I may be dispensed with altogether by hanging the pulleys G- H and shifting-lever K directly in the car A, and changing the pulley from beam I to the shiftinglever K for the shifting-rope and operate it altogether by hand.
