WILLIAM LAT/V, OF ST. PAUL, MINNESOTA.

HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 767,574, dated August 16, 1904.

Application filed October 27, 1903.

To all whom it may concern:

Be it known that I, WILLIAM A. LAW, a citizen of the United States, residing at St. Paul,

in the county of Ramsey and State of Minnesota, have invented a new and useful Hay-Carrier, of whlch the following s a specification.

This Invention relates to certain new and use- ,ful improvements in hay-carriers and tracks attachment thereto of the ends of a sling or device for carrying the load.

Among the objects of my invention are an improved construction of the body of the device, which I shall describe as the carrier, whereby the pulleys are disposed at right angles to each other in order to enable the load to enter the door of-the barn or mow lengthwise and to reverse to the extent of a one-quarter turn after having entered, thus spreading the load in the barn or mow, and consequently causing the load to require less manual handling than would otherwise be the case.

Another object of my invention is by the improved construction of the carrier to enable the load to be hoisted into the barn through a door disposed at right angles to the track, which latter usually extends through the barn, under the peak or gable of the same, from one end to the other. This enables my improved carrier to be successfully utilized where the principal entrance to the barn is a side door.

With these and other objects in view, which will readily appear as the nature of my invention is better understood, said invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims. v

In the accompanying drawings, Figure l is a perspective view showing my improved hay- Serial No. 178,756. (No model.)

carrier mounted upon a track in position for operation. Fig. 2 is a side elevation, partly in section, of the carrier. Fig. 3 is an end view of the same. Fig. 4 is a sectional detail view taken through the track, the carrier, and the locking device, whereby the carrier is temporarily retained in position at a oer.- tain point upon the track. Fig. 5 is a sectional detail view taken on the line 5 5 in Fig. 2. Fig. 6 is a transverse sectional detail view of the track. Figs. 7, 8, and 9 are detail views illustrating the track construc tion at the point where two sections of track are connected. Fig. 10 is a detail view of a special rivet employed for uniting the side members of the track. Fig. 11 is a perspective detail view of one of the track-hangers.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The track 1 of my improved device is composed of two angle-bars l -shaped in cross-section and designated 2 2. These side members are connected at intervals by means of special rivets 3, one of which has been illustrated in Fig. 10 and which consist each of a spacing bar or member a, having upturned ends 5, at the ends of which are cross-pieces 6, which constitute the rivets. It will be seen that when the spacing bars or members 4, with the upturned ends 5, are introduced between the angle-irons 2 2, which have been previously drilled for the reception of the rivet members 6, the latter may be readily clenched, so as to firmly connect the angle-bars 2, forming the side members of the track, which said side members at the same time are properly and evenly spaced apart. Two of the side members 2 2 thus connected form a track-section, any number of which may be employed to make up the track, according to the length of the latter. These track-sections are connected by means of washer-plates 7, inserted from the top and provided at their lower edges with recesses 8 to admit the members 5 of the adjacent rivets 3. The washer member 7 is further providedwith lateral extensions 8, forming abutments for the opposing ends of the track-sections. Underneath the latter I place a flanged truss-plate 10, having lateral extensions 11, filling the space between the ends of the horizontal flanges of the angle-plates constituting, the track. The trussplate 10, as well as the washer-plate 7, is vertically perforated, as seen, respectively, at 12 and 13, for the admission of avertical bolt 14, which being properly inserted and se- The means for suspending the track consist of hangers 15, provided at their lower ends with oppositely-disposed shoulderslo, from which depend the supporting members 17, having T-hcads18 at their lower ends. The supporting members are in practice introduced between the two side members 2 of the track, theT-heads 18 forming the supporting means for the latter, while the shoulders 16 rest upon and engage the horizontal upper edges of the vertical members of the anglebars 2. It will be noticed that by this simple means the track may be readily supported in a horizontal position, any desired number of hangers being employed, the hangers being suspended in any suitable manner under the roof of the barn or structure in which the device is to be employed.

It will be seen that by thetrack construction just described an unbroken length of double track is provided by the horizontal,

members of the angle-irons 2, which constitute the side members of the track.

The car 19 of my improved device is provided with four or more supporting-wheels 20, which are of the usual flanged construction and adapted to engage the track. The car is preferably composed of two separate parts 21 21, connected by bolts 22 and combining to form a ring 23, which is supported below the track. The side members 21 of the car are suitably spaced apart by the side members of the ring 23, and suitably-disposed braces 24 are provided to extend under the track and to prevent the car from jumping the track. The ring 23 serves as a swivel to support the body of the carrier, and it is in,

order to enable the said ring to be properly connected with the carrier that the car or superstructure is preferably made in two separate pieces, as herein described.

The carrier 25 is composed of a crown piece or casting which comprises a flanged ring 26, provided with inwardly-extending lugs 27, 28, and 28. This crown-piece or flanged ring is engaged by the ring 23 of the superstructure and has a swiveling connection with the latter, as will be readily understood. Suitably bolted to the under side of the lug 27 is a pul- This, it

ley-frame 29, and to the under sid es of the lugs 28 28 is bolted another pulleyframe,-30, which is disposed at right angles to the frame 29;. The latter carries a pulley 31, which is disposed a trifle, above and at approximately right angles to a pulley 32, journaled in the frame 30. The flanged ring 26 and the frames 29 30, which are firmly bolted together, constitute the main structure of. my improved carrier. The lug 28 at one end is provided with aprojection 34, which cooperates with the oppositely-located lug 27 to form a guide for the locking device, as will be presently described.

The lower outer or front corner of the bracket 30 is bifurcated, as shown at 35, to form a recess in which an arm 36 is pivotally mounted upon a transverse bolt 37. The diagonally opposite upper corner of the frame is likewise recessed at 38 to afford a bearing for a link 39, which is pivotally mounted upon a bolt 40". Pivotally connected with the lower end of the link 39 is a locking member 40, which is composed of two suitably-spaced side members 41, the free ends of which have pivotal connection at 42 with the free end of the arm 36 and cooperate with the latter to form a rope-lock, the pivotal point 42 being disposed near the lower edges of the members 41 and 36, so that when pressed in a downward direction the upper edges of said members will be forced in the direction of ,each other, thus clamping or biting upon a rope which is passed between the side members or lockingjaws. The link 39 being mounted pivotally at its upper and lower ends,

as shown, will act as a toggle to give the necessary freedom of movement to the lockingaws.

Pivotally mounted between the members 41 of the locking-jaw 40 is an upwardly-extending arm 43, which has a shoulder or offset 44, from which a guide-pin 45 extends upwardly into a socket 46, depending from the upper part of the frame 30 and in which said guidepin is capable of moving freely. A spring 47, coiled upon the guide-pin 45 between the shoulder 44 and a washer 48, disposed against the under side of the socket 46,serves to force the arm 43, and with it the inner end of the locking member 40, in a downward direction, so as to cooperate with the member 36, as

already described, to bite upon the rope passverse to the track and underneath the latter.

The track carries at the point where the load is to be elevated a trip-block 50, which in its preferred construction is provided at its ends with two inclined planes 51, each terminating abruptly in a shoulder or depression The trip-block itself is curved on its under side, and it is provided with upwardly-extending hangers 53, which are perforated for the passage of bolts 54, which are fitted with nuts and washers, whereby the trip-block. is secured firmly in position. The frame 49 of the arm 43, which is intended and adapted to engage the'trip-block, is beveled, as shown at 55, upon the under side of its upper crossbar, so that in the natural course of operation it will readily pass into engagement with the trip-block.

The frame 49 of the trip-arm 43 is permitted to move freely in a vertical direction, but prevented from swinging or oscillating by the guides formed by the lug 27 and thee);- tension 34 of the lug 28, which have been already referred to.

A pair of sheaves 56 and 57 are provided, the frames of said sheaves or blocksbeing provided in the usual manner with hooks 58, to which the sling or other means for attaching the load maybe connected. In the eXample shown in the drawings the hoisting-rope 59 is made fast to the sheave 57, is reeved from thence over the pulley 31, thence down under the pulley in the sheave 56, thence under the pulley in the sheave 57, thence upward through the rope-lock, composed of the members 36 and 40 and cooperating parts, thence over the pulley 32, and to the point where the draft is applied. In operation when the car starts in the direction of the tripblock, which is mounted in proximity to the door of the barn, the trip-block will at the proper time engage under the frame 49, thus elevating such arm and causing it to be retained in an elevated position by the beveled portion of the frame 49 dropping into the proximate recess 52 of the trip-block. The car is thus retained in a stationary position and the rope-lock is opened, so as to admit of the free passage of the hoisting-rope. Draft upon the latter being relaxed, the hoisting pulleys or sheaves 56 57 will descend by their own Weight until a load may be attached thereto. Draft being now applied to the hoisting-rope, the load will be elevated. The sheave 57, which is directly influenced by the hoisting-rope, will rise ahead of the'sheave 56 and will presently strike against the under side of the pivotally-connected members 36 and 40. This will cause the jointed ends of said members to move upwardly, thus lifting the frame 49 of the arm 53 free of'engagement with the trip-block, and the draft being obviously continued the car will pass out of engagement with said trip-block. At the instant it leaves, however, the tension of the track will have a lifting action tending to release the rope fromthe lock; but as soon as the draft ceases the action of the spring 47 will again'cause the rope to be engaged by the locking device and the load will be held suspended, as will be readily understood. The load is dropped at the proper point by ordinary tripping mechanism, which is no part of my present invention.

By the improved construction of the carrier, which has been herein described, the hoisting-sheaves may be so connected with the load that the latter shall be presented end first to the door or opening in the barn in which it is to be deposited, said load being capable of swinging after entering the barn, so as to be placed sidewise in the latter,thereby enabling it to be dropped to such a position that the least possible amount of manual handling will be incurred after the load has been dropped. It is also obvious that my improved carrier will be extremely useful and desirable When the hay is to be unloaded in a barn or mow provided with a centrally-disposed side door, inasmuch as the load may be carried from the center of the track in either direction toward the ends of the barn structure. These and other advantages will be fully appreciated by those familiar with the art to which my invention appertains, and I desire it to be understood that while I have in the foregoing described a simple and preferred construction of my improved haystacker and its related partsI do not thereby limit myself to the precise structural details herein set forth, but reserve the right to any changes, alterations, and modifications which may be resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same.

When, as stated above, the device is used in a barn having a centrally-located side door and the trip-block50 is consequently disposed opposite to the door, it becomes necessary at times for the carrier to pass by said tripblock in order that hay may be carried to both ends of the barn. This is easily efiected by holding the carrier at the quarter-turn while passing the block 50, as will be seen in dotted lines in Fig. 5 of the drawings. The frame 49, forming the upper terminal of the ropelock-operating arm, being disposed tangentially, as shown, or at a distance from the center of the ring 26 of the carrier,will readily pass by the block 50 and enable'the device to be drawn in the direction of either end of the barn or other structure. spring 47 will force thearms 43 in a down- Having thus described my invention, I claim 1.
