HAY ELEVATOR AND CARRIER.

TSPECIFICATION forming part of Letters Patent No. 300,687, dated June 17, 1884.

Y Application filed October 25, mm. (No model.)

as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in hay elevators and carriers; and it consists in the peculiar construction of the several parts, and in the combination and arrangement of the same, as will be hereinafter fully described, and specifically pointed out in the claims.

In the drawings, Figure 1 is a perspective View of the carrier and the turn-table. 2 is a side view of the carrier on the track, and having one of its side plates broken away to show the position of the interior parts. Fig. 3 is a view substantially like Fig. '2,with the parts in different relative positions. Fig. 4 shows in detail the device employed to hold the load at any desired "point below the carrier. Fig. 5 shows in detail the manner of using myinvention on a rod or rope for stacking in the field, 8m. Fig. 6 shows in detail the stop and the catch-block, with modifications of each; and Fig. 7 is aview on a reduced scale, showing the manner of supporting the rail in the ridge of a barn; and Fig. 8 shows an automatic lever to be used as a substitute for the catch-block, when desired.

a is the rail supportcd'by hangers a, which are secured to the rail midway between its sides, and extend up and are made fast to the ridge or roof of the barn or other suitable support.

b is a turn-tableconstructed by cutting outa section of the rail long enough to support the carrier, and having the hangers connected thereto extended up and made fast to a bar,

b,which' is pivoted centrally to abeam or other Fig.

construction, as shown. I provide this turntable with blocks If, so that the carrier will not roll therefrom, and the ends of the turntable and of the rails between which it is supported are provided with hooks 12 so that the turn-table may be heldfirmly as a part of the rail proper, when so desired. This construction is useful when it is desired to reverse the earrier, and also where it is desired to carry the load off into an L or a mow of the barn. This is accomplished by arranging a rail leading into the L with its end terminating at a point within the are described by the end of the turntable in its revolution, all of which will be readily understood on reference to the drawings.

0 c are the side plates of the carrier, from the opposite ends of each of which are projected the hangers c, which extend above the rail (0, and have journaled to them the wheels 0 which run on the rail on opposite sides of the hangers a. The wheels 0 are removable, their journals being held in place by keys, so that said wheels may be removed and substituted for by two. grooved pulleys having long 7 5 hubs, as shown in Fig. 5, for running onarod or rope track. 1

(Z is the trip having the upper arm, (1, constructed with the cross-bar (Z arranged to be caught by the grapple-hook hereinafter described, and the lower arm, (2 is provided with hook d to whicha horse hay-fork may be secured, and the trip is provided with the pulley d. This trip is supported and raised and lowered'by the rope 6, one end of which is se- 8 5 cured to swivel e, which is connected to the carrier by ball-and-socket joint, as shown, and the rope extends down under the pulley cl and then up over the pulley 0 which is journaled in the side plates, 0, and then is carried through a sheave at the end of the track and down to the ground, where ahorse maybe hitched. The car- I rier is provided in its lower side with an opening, 0, into which the arm d of the trip projects when elevated in the operation of the device, 5

' as will be described, and in its upper end it is provided with a recess immediately over the opening 0, and inthis recess the catch-block hereinafter described is moved up and down in the operation of the device.

f is a grapple pivoted between the plates above and slightly to one side of the opening 0 and is provided with the lower hook, f, the arm f and the upper portion, f

g is a catch-block working up and down in the recess formed in the top of the carrier, and its lower end is rested either on the portion f 3 or the arm f 2 when the grapple is in its different positions, as will be described. The construction of this block 9 is shown in detail in Fig. 6, in which figure ac and y are respectively side and edge views of the block 9. The said block is constructed with the lug g, projected laterally from its base, and with the uprights 9 g are lugs projected toward each other from the uprights near the tops of the latter.

At 2, Fig. 6, I show a modification of the catch-block, as will be hereinafter described. when desired, a catching-lever, (shown in Fig. 8,) provided with a notch or lug on the under side to engage with the extension f" of grapple f, may be used instead of the sliding-block having the inwardly-projected lugs is lifted; or the end of said lever may be turned up and provided with inwardly-pro ecting lugs or pins, the same as catch-block, and work with the same stop.

This device is well adapted to be used as a fire-escape. A rod or suitable way is rigged to the side of the building, and the carrier is placed thereon and will travel from end to end by drawing upon the draft-rope in the same manner as it is made to travel on the ways when used in elevating and carrying hay or other materials.

h is the stop, which is shown in detail side and edge views at w. It is constructed with the top plate, h, which is secured on the under side of the rail.

h is a central bar depending from the plate h. From the side of the lower end of this bar are projected the lugs 71.3, which are inclined on their upper faces, meeting in the center and inclined downward toward the opposite ends of the stop. I I

.h h are lugs projected down from the plate h above the ends of the inclined lugs h. The bar h is made of a width about equal to the space between the lugs g on eatch-blocksg, and these lugs are engaged, and the catchblock is raised by the inclined lugs h in the operation of the device, as will be described.

At V, Fig. 6, I show a modification of the stop, in which the inclined lugs h and the uper lugs, h, are extended laterally from a side plate. It will be understood that two of these stops are employed one on either side of the track of the carrierthat when this stop is used the catch-block is constructed as shown at y, with the lugs g projected out and arranged to engage the inclined faces of the lower lugs. These stops 71, it will be seen, are exactly the same at each end, and they will operate the same when the carrier comes from one direction as from another. In practice I secure several of these stops along the rail at points where it is desired to raise the loads, said loads being dropped at any desired point by means of the trip-rope attached to the fork, which may be secured on hook d as before described.

It is frequently advantageous and desirable to carry the load along a considerable distance below the carriage, especially when the point into which the hay or other article is being packed is considerably lower than the rail on which the carrier runs, as it savesthe labor of drawing the load all the way'np' to the carrier, and in order to do this I employ the catch 1, composed of the side bars, i, the antifriction roller 1' and the pawl i and its lever i. The upper ends of the bars i are pivoted or otherwise secured to the carrier-plate c on or near the axle of pulley 6 and they extend down a short distance in front of the rope e, and are then bent across on either side to the opposite side of the rope. The roller 1' is journaled in front of the rope, and serves asa bearing therefor. I prefer to use this roller, though it will be understood any other bearing would answer the purpose, though not so well. The pawl i is pivoted between the lower ends of bars t" on the opposite sides of the rope from the bearing a, the rope passing between the bearings i and the pawl 43. lever t has one end madefast to the pawl ifiand its opposite end is made fast to a cord,i, which extends up through an eye fixed to the side of one of the bars 13, and thence down to within reach of the operator. Thus it will be seen that when drawing the trip and pulley with the load up toward the carriers the rope 0 will pass The freely up through between the bearings i and the pawl 6 but that the rope. 6 cannot pass down between the said pawl and bearing unless the pawl is raised by drawing on the cord *9, thus freeing the point of the pawl from the rope, in which it will embed itself as the rope passes down unless it is freed, as described. I have only shown this catch in Figs. 2 and 4. I regard it asparticularly advantageous for use in the field and in warehouses, &c.; also when the carrier is used as a fire-escape by running ,it on a track suspended at the top and front of a row of buildings.

In Fig. 5 I show the manner in which my stop may be supported on a rod or rope, and in the same figure I show a grooved pulley adapted torun on the rod or rope with the hangers 0, depending from the opposite sides thereof.

In the operation of my invention, when the parts are in the position shown in Fig. 2, it

will be seen the catch-block is rested down on the portion f of the grapple, and that it cannot escape from the stop h on account of the depending lugs h, which prevent its moving out from either end of the stop. N ow, if the trip dis raised, the top of cross-bar (1 will strike arm f of the grapple and raise it and move the portion f 3 out from under the catch-block g, and the latter will fall onto the arm f and can thus slide out of the stop h. The hook f in the meantime has passed under bar (1 and securely holds the trip with its load, which may be carried to any suitable point desired. Now, suppose the several parts are in the position shown in Fig. 3, and that the stop h, therein shown,is directly over the point where it is desired to drop the fork and raise the load. It will be seen that as the carrier approaches the stop the .lugs on the catchblock 9 will engage the inclined faces of the lugs If and the block will be raised, releasing the grapple which has before been held by the block resting down in front of the portion f and the trip with the fork escapes, drawing the grapple into the position shown in Fig. 2, with the portion f 3 under the catch-block 9.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s
