HAY-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 351,443, dated October 26, 1886.

Application filed M'ay Q0, 1886.

To @ZZ whom ibm/ay concern:

Be it known that we, CHARLES E. HUNT, NATHAN B. HELM, and HENRY L. FERRIS, residents of Harvard, in the county of Mc- Henry and State of Illinois, have invented certain new and useful Improvements in Hay- Elevators; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others ro skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in hay-elevators, and is fully described and explained in the following specification, and

. I5 shown in the accompanying drawings, in

which- Figure l is an elevation showing the inner face ofone-half of our elevator and the locking mechanism attached thereto. Fig. 2 is a similar view of same parts, the position of the locking parts being changed. Fig. 3 is a vertical section through the line x x, Fig. l, the locking mechanism being removed and the view being in the direction indicated by the arrow in Fig. 1; Fig. 4, a side elevation looking in the direct-ion indicated by the arrow in Fig. 8.

In these views, A is an elevator-track of any desired form. A is a stop fastened thereto.

B is an elevator-frame, and C C are the rollers, that rest on the track and support the frame. A rope, D, has one end fastened to the frame B, at a point, B', on one side thereof, and is carried from said point of attachment across and approximately at right angles to the frame,

and passes upward between two grooved pulleys, E E', mounted on the opposite side of the frame from the point B. The portion of the rope between the pointB and the pulleysE E 40 forms a loop which hangs in a vertical plane at right angles to the line ofthe track, andthe pulleys E E are on opposite sides of and equally distant from the plane of the loop. Each of the pulleys E E is mounted on a horizontal pivot, and the two pivots are supported at their inner 'ends by the body of the frame, and at their outer ends by a guard, M, lying outside the pulleys and fastened to the frame.

It is evident that the rope D, after being Serial No. 202,814. (No model.)

be carried horizontally over either of them, and may thus pass to a pulley at either end of the track A. In fact, Fig. 1 shows the rope resting on the pulley E. while Fig. et shows it resting on the pulley E. The rope may in fact be transferred .from one4 position to the other by simply swinging it aro'und, the construction of the parts being such that it cannot become misplaced during the operation of changing.

The loop between the point B and the pulleys E E supports a forkpulley, F,Vmounted in a suitable housing, G, which is provided with an upward-proiecting headed pin, H. A locking mechanism@ K L, is mounted between 6 5 the two parts of the elevator-frame, and serves to lock the frame to the stop A', or to support the pin H, housing G, and pulley F. These parts are shown, described, and explained in aformer patent issued to us, and need not be 7o explained here.

It is evident that by hanging the forksupporting loop across the elevator-frame, and mounting the two pulleys E E on opposite sides of the plane of the loop, the elevator is rendered reversiblel without the use of any swiveling device whatever. The hanging of the loop across the carrier is not broadly new in this application, since it is illustratedin oui.l pending application No. 195,279; but the com- 8o bination of the transverse loop with the two pulleys is new and a valuable improvement.

Ve do not limit our invention to the exact forms shown, since these may evidently be varied without affecting the operation of the 8 5 mechanism. The locking mechanism shown is only intended as an illustration of the operation of our invention; but any other form operated by a central pin may be substituted, and will be equally suited to the use of our invention.

Vhat we claim as new, and desire to secure by Letters Patent, is-

l. The combination, with an elevator-frame adapted to move on a suitable ltrack, of an op- 9 3 eratingropc fastened to the frame at one side thereof' and carried across beneath the frame in a plane at right angles to the line of the track, and two rope-supporting pulleys jour- 5o carried upward between the pulleys E E, may

n aled to the frame on the side opposite the roo point of connection of the rope, 'said rope being carried upward between said pulleys, and said pulleys being symmetrical with reference to the plane of the rope, substantially as and for the purpose set forth.

2. rllhe combination of theA elevator-frame, the pulleys E E', journaled on one Aside thereof, the rope D,lying between said pulleys and carried thence across beneath the frame and fastened to the frame at a point opposite the space between the pulleys, and thefork-pulley F, suspended on the rope between the pulleys E E and the end of the rope attached t o the frame, substantially as and for the purpose set forth.

3. The combination of the track A and stop A', the frame B, having rollers C, the latching mechanism I K L7 the pulleys E E', journaled NATHAN B. HELM. HENRY L. FERRIS.
