HAY-CARRIER.

SPECIFICATION forming part ofY Letters Patent NO. 785,361, dated March 21, 1905. Appiicaiou inea August 12, 1904. serai No. 220,530.

To all whom, it may concern:

Be it known that I, WILLIAM F. JACOBS, a citizen of the United States, residing at'Ottawa, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Hay-Carriers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to hay-carriers of that class embracing a supporting-track, a carriage which rests and travels on said track, a hoisting pulley-block, means for locking the carriage at one place on the track and locking the' pulley-block to the carriage, together with means for simultaneously releasing the carriage from the track and locking the pulley tothe carriage when the load has been elevated and for locking the carriage to the track and releasing the elevating-pulley from the carriage when the carriage is returned to its locking position after the load has been deposited.

The invention'consists` in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, illustrating my invention, Figure l is a view in side elevation of`a hay-carrier embodying my invention. Fig. 2 is a plan view of the carriage and parts thereon detached from the track. Fig. 3 is a vertical section taken upon line 3 3 of Fig. 4:. Fig. 4 is averticalcross-section taken upon line 4 4 of Fig. 3. Figz is a plan section taken upon linev 5 5 of Fig. 1. Fig. 6 is a sectional-view of the track and an end view of the stop-plate thereon.

As illustrated in the said drawings, which show in one practical form an apparatus embod ying the several features of my invention, A indicates an overhead track which is intended to be supported in a barn or elsewhere and'which usually extends over the place or iioor ugon which stands a wagon to be unloaded and over a mowor place in which the hay is to be deposited. Said track may be supported by any suitable means, not necessary to be illustrated, as they form no part of the present invention.

B indicates the upper and O the lower part ofthe carriage-frame, said parts B and O loeing joined by a swivel connection permitting the lower part of said carriage-frame to be turned or rotated relatively to the upper part. The upper member B of the carriage is provided with four supporting-wheelsnB B', which rest and roll upon the track A, and the lower f part O .of the carriage is provided with two sheaves or pulleys D D.-

E indicates the frame of they pulleyeblock, which is provided with a pulley-wheel F and which isl adapted to be raised and lowered relatively to the carriage-frame by means of a rope G. which also serves to move the carriage along' the track A. Said pulley-block will usually have attached to it a hay-fork or other like device. Said rope G is engaged with the pulleys D D and passes around the pulley F of the hoisting-block in the usual manner.

M indicates a lock-plate which is secured to' the track A over the place from which the load is to be hoisted.

I I are locking-dogs on the lower part O of the carriage for locking the pulley-block to the carriage, J an actuating-bar for operating said dogs, and K a central spindle which engages said bar J and is attached at its upper end to a lockinghead L, adapted to engage the lock-plate M.

The four track-wheels BIS rest upon or engage suitable lateral bearing-surfaces upon the track A, and the said upper member of the carriage is provided with four arms b I),`on the ends of which said track-Wheels are mounted, these parts being arranged in a common and familiar manner. At its lower part or base the said upper portion B of the carriage is provided with a horizontally-arranged rigidly-attached internallyngrooved swivelring B2, which engages a circular swivel-plate O, formed on or attached to the top of the lower part O of the carriage. Said lower part O of the carriage consists, mainly, of two side plates C2 O2, between which the pulleys D D are pivoted and which are separated at their lower parts to receive between them the pulley-block E when the latter is in its elevated position or drawn upwardly into engagement with the carriage. Said side plates C2 C2 are shown as joined at their upper ends to the swivel-plate C, which is made in two parts or halves, each of which is rigidly attached to or formed on one of the side plates. Said side plates C2 of the lower frame are also connected with each other by means of stud-bolts e c and by the pivots 0l d of the pulleys D. yThe swivel-ring B2 on the upper carriage-frame B is likewise formed of two semicircular parts or pieces, which are severally cast integral with two side plates B3 B3, constituting said upper part of the carriage, the. parts or halves of said ring B2 being joined by bolts b, inserted through laterally-extending lugs on the exterior of the ring and which serve to rigidly connect the side plates of said upper frame at the lower end thereof.

The locking-dogs I I for holding the hoisting-sheave E in its elevated position or interlocked with the lower part C of the carriage are mounted on horizontal pivot-pins z' e', arranged parallel with and outside of the side frame-plates C2 C2 and mounted in outwardlyextending lugs or ears c c, formed on said side plates -at either side of vertically-extending slots c2 c2 therein, as clearly seen in Fig. 5. Said dogs are arranged to hang or depend from said pivot-pins and to swing in transverse vertical planes inwardly and outwardly relatively to the side plates, the lower ends of the dogs being adapted to extend through said slots or openings c2 c2. Said lower ends of the dogs are hook-shaped or provided with inwardly-extending arms adapted to engage a locking-plate E', which is located at the top of the pulley-block E and is connected with the side plates of said block by means of four upwardly-extending bars e e, two of which are connected with each of the said side plates and are separated from each other, so as to afford a wide space or opening beneath the side margins of the said locking-plate E' to permit the engagement of the ends of the dogs I I with the lower surfaces of the said side margins of said locking-plate. The lower surface of said locking-plate E or the side margins thereof which are engaged by the ends of said dogs I I are convexly curved, so that the ends of said locking-plate to which the arms e e are attached are above the level of the center part of said plate. As a result of this construction when the pulley-block E is sustained or supported by engagement with said dogs its lower end may be nswung or moved in the plane of the carriage Without affecting the engagement of the dogs therewith, thus permitting the pulley-block to take a forwardly or rearwardly inclined position in case the point at which the hay-fork or other lifting device attached to the pulley-block is not directly beneath the carriage when it engages the load and enabling said locking-dog to engage said locking-plate equally well whether the pulleyblock stands in a vertical or inclined position when drawn upwardly between the side plates of the carriage. This will be readily understood from Fig. 3, wherein the pulley-block is shown in its inclined position in dotted lines and the dogs I engaged with the locking-plate E near one end of the same.

The actuating-bar J is arranged horizontally and extends transversely of the lower carriage-frame C, with its ends extending through the slots c2 c2 in the carriage-frame and through slots z" c", formed in the dogs I between the lower ends of the same and the pivots thereof. Guide-lugs jajs project from the sides of the bar J in position to bear and slide upon the inner faces of the side plates C2 C2 at the sides of the slots c2 c2 therein. Said bar J is provided near its end with guide-pins j, which extend therethrough and engage inclined guide-slots 2 in the dogs, which guide-slots are inclined downwardly and outwardly and preferably are nearly vertical at their upper ends. Said bar J is pivotally connected with the lower end of the spindle K, which has a head 7c on its lower end below thesaid bar. The locking-head L is mounted to slide vertically in the upper part B of the carrier, which latter is provided with lateral guides B4 BJ, Fig. 2, which are engaged by the sides of the head L. Said locking-head Lis provided with two upwardly-extending arms L L, having at their upper ends two inwardly-extending locking-lugs ZZ. A swivel-ring J surrounds the upper end of the spindle K below and inV contact with the locking-head L and is rigidly connected with the bar J by two inclined braces j2 f2.

The lock-plate M is rigidly secured to the track A beneath the same and will be located over the point from which the load is to be hoisted-that is to say, in unloading hay from a Wagon the said lock-plate will be located over the wagon. Said lock-plate embraces a vertical web M, which is arranged centrally beneath the track and provided at its lower margin with longitudinally-arranged laterally-projecting guide-Hanges M2. At its end portion each of the ianges M2 is provided with outwardly and downwardly oppositely inclined guide or cam surfaces m m and at the center of its top surface between said opposite inclined surfacesY m m with a lockingnotch or depressed portion having at its ends v inwardly facing shoulders m. The lower surface of each flange h/ 2 is inclined downwardly at its ends to form inclined cam-surfaces m2 m2, corresponding generally with the downward inclination of the cam-surfaces m m, while at the central part of the lock-plate are formed two downwardly and inwardly inclined cam surfaces 'm3 m2, which meet to form adownward central projection. The upper end of the locking-head L between the arms L L is provided with an upwardly-fac- IIO ing surface Z', located at a distance below the lugs Z Z substantially equal to the thickness of the flanges M2 M2 or the distance between the upper and lower cam-surfaces m and m2 of said flanges. As a result of this construction the surface Z' of the said locking-head will strike the inclined cam-surface m3 at the center of the lock-plate as the locking-head approaches the center of the lock-plate and will be forced downwardly thereby, thus insuring the descent of the lugs Z Z into locking engagement with the central notches of said lock-plate. Similarly when the locking-head is lifted to release it from said notch and the carriage moved away from its central position the said upper surface of the locking-head L will ride on the inclined lower cam-surfaces m2, and thus force the head downwardly should the weight of the parts be insufficient to keep the said lugs Z Z in contact with the cam-surfaces fm, fm, in such movement of the carriage. Said lock-plate Mis so arranged with relation to the vertically-movable locking-head L of the carriage that when the said carriage is traveling on the track and the head L is in its lowermost or depressed position the lugs Z Z on the head will be in position to pass over or just above the outer ends of the `upwardlyfacing inclined cam-surfaces m m. Said camsurfaces m,` fm, moreover, are so arranged that the said lugs Z Z move along the same toward the center of the lock-plate. Said cam-surfaces will operate to lift the head L until the lugs pass from the ends of said surfaces m and enter the notch formed between the shoulders fm l117/. When the lugs Z Z enter said notch, the head L will descend, being no longer supported by the cam-surfaces m m, and the carriage will thereby belocked in central position with respect to the locking-plate and cannot be moved from said central position until the head L is lifted to permit the passage of the said lugs Z Z out of said cen tral notch. The parts are so arranged, moreover, that when the lugs Z Z rest in the said notch the head L will be held in its elevated position, and the operating-bar J, which is connected with the head, as above described, will be held near the upper limit of its movement. rI`he inclined slots z" Z2 in the dogs I are so arranged with respect to the guidepins L7' that when the said bar J is in its elevated position the dogs will beheld with their lower ends in an outward or unlocked position; but when said bar J is depressed the lower ends of the dogs will be drawn inwardly in position to engage the pulley-block E. The cam-surfaces fm, m of the locking-plate ,M therefore constitute, in connection with the head L and its lugs Z Z, means for lifting the bar J and throwing outwardly the locking'- dogsI when the carriage in moving along the track is brought into a 'central position with respect to the locking-plate. yIn other words, supposing the carriage is at one end of the ment, as will be the case when the lugs are i passing over the inner or upper ends of the cam-surfaces m, the guide-pins will be in the upper parts of the guide-slots 21222, so that the slight downward movement of the lugs Z Zand head L required for the engagement of the said lugs with the central notch of the locking-plate no considerable outward movement of the said dogs will occur, and said dogs will not by such slight downward movement of the bar J be caused to again engage the pulley-block. As the lugs pass inwardly over the shoulders fm m' the top of the lockinghead L will strike the cam-surface m3 and be drawn positively downward thereby, so that engagement of the lugs Z Z with the central notch will be insured should the gravity of the head and attached parts be insufficient to produce a sufficiently quick downward movement of the head to effect such engagement. The space between the shoulders my m is preferably made considerably greater than the width of the lugs Z Z, so as to give ample time for the lugs to descend into the notch before IOO they strike the shoulders m m', toward which with its hay-fork, will descend to receive a load. When, however, the pulley-block, with its load, is again lifted by means of the rope and said pulley-block is brought in'to position between the side plates of the carriage, said pulley-block will be drawn upward far enough to bring the plate E in contact with said actuatingbar J, with the result that not only will `the dogs be thrown outwardly through the lifting of said bar, but the lugs ZZ on the locking-head will be lifted above the upper ends `of the inclined surfaces m m of the lock-plate,

and the continued pulling on the rope will then shift the carriage away from its central position beneath the lock-plate. As soon, however, as the carriage begins to move away from its central position downwardly facing cam-surfaces m2 at the end of said lock-plate will act on the top of the head L below the lugs Z Z, thereby depressing or forcing down.- wardly the actuating-bar J and throwing inwardly the locking-dogs I until they are engaged with the locking-plate E. Such downward movement of the head L and lockingplate usually takes place by gravity as the carriage is moved from its central position and the lugs Z Z travel downwardly over the cam-surfaces fm, m; but in order to insure a certain locking of the pulley-block to the carriage before the latter passes from engagement with the locking-plate said cam-surfaces m3 m3 are arranged to operate on the lockinghead, so as to thrust the same positively downward in the manner described.

The track A and the locking-plate M emwheels B B of thecarriage rest and roll.

The web (Z is extended below the Hanges ct' (Z and is provided with an enlarged or widened part or T-head a3, by which-the stop-plate M is secured thereto. Said web a of the track also preferably extends above the horizontal flanges c a and is likewise provided with an enlarged upper margin or T-head to facilitate the attachment of the track to supporting devices by which itis suspended and also to give greater stiffness and -rigidity to the track as a whole. The said locking-plate M is provided at the end of its web portion Ml with enlarged parts or blocks M3 M3, which are provided in their upper ends with longitudinally-extending T-shaped grooves, Fig. 6, adapted to receive the T-head on the lower margin or edge of the depending web a of the track A. Setscrews m3 m3 are inserted obliquely through the blocks M3 M3, so as to bear against the lower surface of the web a and to thereby firmly clamp the lock-plate to said track. Said set-screws m3 ml are arranged obliquely in the heads M3 M3 andare arranged to bear obliquely on the lower surface of the track, so that they will be adapted to effectively resist end thrust on the stop-plate due to the impact of the locking parts of the carriage against the same when the carriage is arrested upon reaching a central position beneath the lock-plate by engagement of the lockinglugs Z Z with the shoulders m/ at one end of the central notch in the flanges of said lockplate.

The swiveled connection of the lower part of the carriage-frame with the upper part thereof afforded by the swivel-ring B3 and swivel-plate C', together with the pivotal or' swiveled connection of the lower end of the locking-head L with the actuating-bar J, enables the said lower part of the carriage to be turned or rotated on the upper part, so as to reverse its position or bring the pulley D, over which the running end of the rope passes, toward either end of the track. In unloading with a carrier it is often necessary to change the direction in which the carriage runs, so that it shall move from the lock-plate toward one end or the other of the track, as in delivering hay to opposite ends of a mow, and this may be done in the construction described by merely rotating the lower part of the carriage a half-turn and carrying the running end of the hoisting-rope toward the end of the track to which it is desired that the carriage should travel.
