' WAYNE, MICHIGAN.

HAY-CARRIER.

PECIFICATION forming part of Letters Patent No. 330,290, dated November 10, 1885.

Application filed March 5, 1885.

To all whom it may concern:

Be it known that :1, WILLIAM W. BownR, of Romulus, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Hay-Carriers; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and novel improvements in hay-carriers; and the invention consists in the peculiar construction and means employed for locking and tripping the fork-pulley, in the peculiar construction and arrangement of a turn-table, and in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter set forth.

Figure l is a perspective of my improved carrier, with a portion of the track broken away to show the trip-lever. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical longitudinal section showing fork-pulley locked in the carrier. Fig. 4 is a longitudinal section of the same with the fork-pulley detached. Fig. 5 is a vertical central cross-section through the carrier. Fig. 6 is a detached perspective in detail of trip mechanism.

I provide a turn-table which allows the device to be operated from either side of the trippingcam. I provide a trippingcam which provides a parallel space for the triplever to allow ample time for the uncoupling of the fork. I provide peculiar means for locking the turn-table to the carriage and for adj ustability in the fork-head.

Referring to the drawings, A designates the frame of the carriage suspended from a track, (1, by rollers B. The carriage is formed of two plates bolted together, the lower portion of both halves forming a cylindrical bearing above collar D for the turn-table P. (See Figs. 1 and 5.) Inside the collar D is formed the flaring throat a, and between the parts of the carriage at a is pivoted the looking-pawl E.

J designates the'fork-carrier, having hooked head M upon athreaded shank, L, adj ustably secured in the carrier, and having also a pulley, j, under which passes the rope I. The rope I is secured to one arm of the turn-table Serial No. 157,731. (No model.)

I, as seen at t, and after passing under the pulley j passes over another pulley, K, journaled in the opposite arin of the turn-table, and thence over a pulley, H, which is secured to a convenient position in the barn, as is usual in this class of devices. Above the pulleys K is pivoted in the turntable a hooked latch, H, which has aweighted end adapted to fall into a space in the carriage and prevent the turntable from turning on its bearings. When the device is not in use,the pulley-block H is hung on the hook end of the latch H, bringing all the parts conveniently together. The latch serves to lock the turn-table to the carriage in either of its operative positions.

The tripping-cam plate G is secured camsurface down to the under side of the rail 0, and its cam consists of a straight portion, on, and two oblique portions, n, as shown in Fig. 6. The trip-lever F is pivoted to the carriage at f, and has an upwardly-extending lug, h, which is adapted to engage the caingroove m n of the plate G.

The hook-lever E is pivoted within the carriage A, and has a hook portion, b, adapted to pass under the head M and lock the fork-carrier to the carriage. WVhen thus locked, a lug, 0, projecting from the lever E,is engaged by a lug, h, depending from the trip-lever F, as shown in Fig. 6, and when in this position the lugh of said trip-lever is entirely out of contact with the cam-plate G. The hook-leverE has aweighted end, e, and the normal position of this lever is with the weighted portion resting upon a bearing formed by the upper portion of the throat a, as seen in Fig. 4.. When in this position, the lug h of the trip-lever lies in the straight portion m of the cam-slot, and the lug h of that lever is disengaged from the projection c of the hook-lever.

In the operation of the device, the parts being in position as seen in Fig. 4, proper tension upon the rope I will lift the carrier J and its carried load until the head M comes in contact with the weighted arm e of the hook lever E, and oscillates that lever upon its pivot until the hook b passes under said head. (See Fig. 3.) A continuation of thetension moves the carriage A, and the lug h of the trip-lever, passing into the inclined portion a of the cam,

throws the lug h intoengagement with the lug c of the lever E and locks the parts in such position. (See Fig. 6.) Upon the return of the carriage (operated by any known means to compel such return) the lug h rides into the cam portion-n until the trip-lever is disengaged from the hook-lever E, and the said hook-lever falls to its normal position, as shown in Fig. 4.

I attach importance to the cam-groove having the straight portion m, for the reason that it assures sufficient time for the hook-lever to resume its normal position and allows arange of freedom to the movements of the carriage.

I also attach importance to the adj ustability of the hooked head and its shank L, for the reason that wear upon the head may be readily compensated for and the relation of the pul- Icy-block j and tripping-lever may be readily adjusted to suit.

The device may be operated in the other direction by simply lifting the Weighted end of the latch H and turning the turn-table onehalf around. The hook on this latch furnishes a very convenient bearing for the pulley-block when the device is out of use, as seen in Fig. 3. When the carriage passes the cam-plate G, guide-plates O on said carriage hold the said carriage firmly in position.

What I claim as new is l. The combination, with the hook-lever E and trip-lever F, of the cam-plate G, having groove with inclined portions n n and straight portion m, as and for the purposes set forth.

2. In a carrier, substantially as described, the weighted lever H, having hook, as shown, combined and adapted to serve with the pulley-block H, as and for the purposes set forth.

3. The combination, with the Weighted hook-lever E, having projection c and hook I), of the cam-plate G, having groove m n, the trip lever F, having lugsh and h, and the fork-carriers, having head M, as and for the purposes set forth.
