HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 314,872, dated March 31, 1885. Application filed February 4, 1885. (No model.) I

To all whom it may concern:

Ohio, have invented certain new anduseful Improvements in Hay Elevators and Carriers;

and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hay elevators and carriers.

Hitherto it has been necessary to transfer the lead of the draft-rope from one end of the railway to the other in order to make the elevator travel in the opposite direction, or, in cases where the draft-rope is kept in position leading from the elevator in both directions, it has been necessary to change the hoistingpower from one draft-rope to the other, thus causing a loss of time and rendering it impracticable to run the elevator alternately to the right and left in unloading.

The object of my present invention is to provide means for operating the elevator which will admit of its being run to the right and left of the load at pleasure without changing the attachment of the ropes to the power, and which will admit of locking the elevator in any desired position along the line of travel, a further object being to provide an elevator which may be operated by a single rope in the ordinary manner, or by a double rope, as above mentioned, a further object being to provide a simple device for automatically locking the movable block to and releasing it from the elevator; and with these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the elevator in position for use in a barn or store-house, showing the improved means for operating the same. Fig. 2 isaview of the elevator proper, in side elevation, provided with a single rope. Fig. 3 is a transverse vertical section through the locking mechanism, and Fig. 4'is a plan view of the A represents the frame of a barn or storehouse provided with the elevator-way'a, extending along below the'ridge to within a short distance of the ends; or it may extend to and beyond one or both of the ends for taking loads in at the peaks, if desired. The barn or store-house here represented, however, isvarranged for mows on the right and left of a central driveway, a.

B represents the elevator-carriage supported from the wheels b,which travel on the way a. The carriage B is provided with a pair of loose pulleys or sheaves, 0, having grooved faces, and located in the same plane near one end of the carriage. The double rope, consisting of the parts D D, is secured to the end of the carriage opposite the pulleys G, and passes from thence about the sheave e in the movable block E, and thence upwardly between the pulleys O. From this point the parts D D separate, the part D engaging the pulley nearest the end of the carriage, and leading in the direction of the way a to a stationary pulley, F, at the end of the barn, and the part D engaging the other pulley, C, and leading in the opposite direction to a stationary pulley, F, at the opposite end of the bar from F. From the pulleys F F the parts D D approach each other toward a pair of stationary pulleys, f f, conveniently located over one end of the driveway, around which they pass, and from thence lead, parallel to each other, downwardly to apair of stationary pulleys, G G,'located near the ground or on a level with the line of draft, and, passing about these, lead to the draft-bar s, to which they are attached.

At a point sufficiently distant from the palleys G G to admit of elevating the movable block E,with its load,fro1n the floor to the elevatorcarriage B an incline, H, is located, at the top of which a stationary wheel or pulley, h, is firmly secured. The incline H and wheel h are so arranged relatively to one another that as the bar s is drawn forward-by a horse,

for example-the said bar will engage the incline and slide one part of the rope D D around the wheel. Thus, suppose the blockE, with its load, be ready to be elevated. The horse 5o cam for operating the locking mechanism. draws the bar 8 toward the incline until the too and travels back I 5 line of travel by taking a the carriage at k,

0 it to one side. i

.. isadapted to engage the face of a double cam,

' 5 the loop on the block E 140 as the hook leaves the it automatically falls beneath the loop and of one large rope,

travel, the carriage may onits track forthe purpose of elevating or first starting a mow,

sity for locking the load to the carriage, thus of; the several parts parting from the spirit and scope of myinrope D D passes about the wheel h. At this moment the block E strikes the latch and releases the carriage, and its direction will be determined by the direction the horse turns toward the pulleys G G. For example, if the horse turns in the direction of the arrow 41:, the draft will be upon the part D, the part D will be slacked, and the carriage will move toward F. If, on the other 10 hand, the horse turns in the direction of the arrow 1 the draft will be upon the part D, the part D will be slaeked and the carriage will move toward F. The carriage may be stopped and locked in any position along the half-turn with the rope about a pin or arm, I, near the wheel h. The above-described arrangement also does away with the necessity of locking the block E to the carriage, as the parts of the rope-D as-soon as they are placed about the wheel h, will prevent the block from descending. It is advantageous, however, to have locking devices for general use, and in the present case they consist of the latch-hook K, pivoted to and adapted to swing transversely to the carriage. The lower end of the hook K- is located above. the loop e on the block E, and the latter as it moves upwardly engages the beveled end of the hook and rocks The upper end of the hook K L, secured to the under side of the way a and rock the hook to one side. A guard, M, acts in conjunction with the hook K and prevents from receding with the hook when the latter is rocked by engagement with the cam, thereby disengaging the Loop from the hook. The loop 6 as it rocks the hook K disengages it from the cam L, and cam to the right or left locks the block E, with its load, in elevated'adj ustment.

H 1 By'the use of two small ropes in the place as heretofore commonly used, the draft is applied equally inopposite directions during the hoisting, thus holding the elevator in position over the load, the carriage may be stopped at any point in its be held at any point lowering the movable block by shifting the draft-bar to the right or left on the rope, the rope for this purpose being continuous from 55 its startingpoint on the carriage to its return thereto, and by moving the incline and turning-post with its pulley nearer to the barn or store-house the load may be elevated just enough to clearthe edge of the mow, as in there being no necessaving time and travel in unloading. It is evident that many slight changes might -beresorted-to in the -form and arrangement described without-devention; hence I do not wish to limit myself strictlyto the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an elevator adapted to traverse a track in different directions, of a draft rope or ropes connected to the elevator and to the power, and adapted to raise the elevator and move it along the track in either direction without changing the attachment of said ropes.

2.. An elevator and carrier adapted to be elevated and moved in opposite directions by the same rope or ropes without changing its attachment to the actuating-power.

\ 3. The combination, with a carrier and an elevator, of a pair of ropes connected at one end to the carrier and passing under the eleto the actuating-power, whereby the elevator can be raised and lowered and moved in opposite directions without changing its attach ment to the actuating-power, substantially as set forth.

4. The combination, with an elevator and carrier, of two ropes attached thereto, and to a draft-bar for elevating the load and moving the carriage in opposite directions, and a pulley or stop for changing the direction of the draft, and thereby causing the carriage to move in either direction along the track, as set forth.

5. The combination, with an elevator and carrier, ofan operating-rope leading there-- from and returning thereto, forming a circuit, and a pulley for changing the direction of the draft, and thereby determining the direction of the movement-of the carrier, substantially as set forth.

6. The combination, with the elevator and v a stationary cam, of a hook gravity-latch having a rocking motion transversely to the length of the carriage, and adapted to be positively operated by the cam and movable block, substantially as set forth.

' 7. The combination, withv the elevator and a stationary cam, of a hook-latch adapted to rock transversely to the carriage, and a sta tionary guard adapted to act in conjunction with the latch in releasing the movable block therefrom, substantially as .set forth.

8.
