Specification of Letters Patent.

I Application filed April 13, 1908. Serial No. 426,735.

To all whom it may concern:

Be it known that I, WILLIAM GUTENKUNST, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Hay-Carriers, of which the following is a specification.

My invention relates to improvements in a certain hay carrier for which Letters Patent 9 of the United States Number 790,891 were issued to myself and Charles Av Gutenkunst on the 30th day of May, 1905, and my present improvements pertain more especially to the mechanism for locking the rope at a fixed 5 point against a stationary bearing both automatically and manually, and the same is explained by reference to the accompanying drawings in which,-

Figure 1 represents a side view of the cara rier upon its supporting track, part broken away to disclose the interior. Fig. 2 is a side view of the carrier, carrier supporting track, carrier retaining bracket supported from said track and a hoisting rope and tackle block. 5 Fig. 3 is a vertical section, drawn on line X-X of Fig. 2. Fig. 4 is a front view, and Fig. 5

is a side view of the mechanism by which the clamping cam is engaged with and disengaged from the hoisting rope, such parts being removed from the carrier frame, and Fig. 6 is a detail, part in section of a part of the tackle block and pulley which is adapted to be used in connection with the hay sling.

Like parts are identified by the same reference characters throughout the several views.

1 represents the track upon which the car rier is adapted to be supported.

2 is a carrier retaining bracket which is se- 3 cured at a fixed point to the track as hereinafter described and serves to hold the carrier at a fixed point upon the track, as the tackle block 3 with its load is being elevated.

4 is a hoisting rope.

The carrier proper comprises the carriage 5, pulley supporting frame 5 with its locking and releasing mechanism. The carriage 5 including the rollers B, B, and roller retaining brackets C, C, is permanently supported J in the same relative position to the track while the frame 5 with the locking and releasing mechanism is revolubly suspended therefrom as hereinafter described, whereby the carrier may bereversed and run in either direction upon either side of the retaining bracket 2. The carrier 5 is automatically locked in engagement with the bracket 2 by the retaining catch 6 and said catch 6 is adapted to enter the retaining recess 7 of the bracket and be automatically engaged by and between the shoulders 8, S, as the carrier is being moved horizontally along the track.

-The catch 6 is pivotally supported from its retaining bearings 9 upon the pivotal bolt 10 which bolt is s0 located at one side of the center of gravity of said catch that the upper arm of said catch is caused to bear against the vertical surface of the diagonal bearings 11 of the bracket until it reaches the open recess 7 when said upper arm drops into said recess and thereby holds the carrier in place at a fixed point beneath the track. The re taining catch 6 is adapted to be disengaged from said recess 7 in two different ways. First by contact of the tackle block as it is being raised with the buffer-bar 12 and, second by the manual act of the operator when drawing upon the releasing cord 15 as hereinafter described.

Motion is communicated from the buffing bar 12 to said catch 6 through the integrally formed arm 18 whereby said catch is thrown back out of the engagement with the carrier retaining bracket. The catch 6 is disengaged from said bracket manually at any time before the load is raised or before the tackle block is brought in contact with said bulllng block by drawing downwardly upon said cord 15. Motion is communicated from the cord 15 to the catch 6 through the lever 16, lug 17, bu'l'ling bar 12, and said integrally formed arm 18, whereby said arm 18 is thrown upwardly by the bui'ling bar and said catch 6 is thrown outwardly and away from its retaining bracket.

The hay carrier is thusfrec to move in either direction from said bracket along the track. It will be understood that when the carrier is out of engagement with the retaining bracket 2, the hoisting rope 4 will be automatically locked and prevented from being drawn downwardly, by the weight of the load suspended from the tackle block, by the clamping cam 19. As heretofore constructed the clamping cam 19 was pivotally supported at a fixed point from the carrier frame and adapted to clam the rope between its periphery and the pu ley 40 over which. the rope is adapted to run and said cam was thrown out of contact with the rope by a laterally projecting lug formed integrally with the vertically moving bar 14. By my present improvement, however, the clamping cam 19 is pivotally supported between the walls of the carrier frame in such a position as to clamp the rope below the pulley 40 and between the periphery of the cam and a stationary bearing 40 of the carrier frame and said clamping cam is connected with the vertically moving bar 14 by a link 14 and pivotal bolts 15 and 16.

It will be understood that when clamping the rope as heretofore between the convex surfaces of the pulley and eccentric clamp the rope is liable to be worn in two much quicker than when clamped against a stationary surface as shown by my present improvement. clamping the rope as heretofore between two moving surfaces a much greater pressure is required to hold the rope and sustain the load than is required when clamping the same against a stationary surface as shown. It will also be understood that when releasing the cam as heretofore by the laterally projecting arm of the vertically moving bar 14, the power was applied to such cam near its pivotal support while by my present form the link 14 is connected with such eccentric near its periphery whereby the same movement of the vertically moving bar 14 is applied to said cam with substantially uniform power at all times whereby the power required for releasing the cam from the rope is greatly reduced as compared with the device shown in said patent.

Three different means are provided for releasing the hoisting rope from the clamping cam. First, the rope is automatically released from the clamping cam by the action of the bracket 2 as the carrier is brought into locking engagement therewith. Second, the hoisting rope is manually released from the cam when the carrier is located upon either side of said bracket 2 by drawing upon the operating cord 15. And third by the action of the buffing bar as the tackle block is raised.

The required movement is communicated to said clamp from the bracket 2 for automatically releasing the hoisting rope 4 as the carrier is brought into locking engagement with said bracket by contact of the latch 20 with the angular vertical walls 11 of said reppining bracket as more clearly indicated in It will be understood that as the latch 20 is moved horizontally along the angular walls 11 its up er arm 21 is forced outwardly by said angu ar walls whereby its lower arm 22 is thrown upwardly beneath the head 23 of the vertically moving bar 14 whereby said baris drawn upwardly when motion is communicated therefrom as previously stated to the clamping cam 19 through said link 14 and pivotal bolts 15 and 16, whereby said cam 1s drawn out of contact with the hoist- It is also obvious that when.

ing rope. The rope is released and the tackle block is permitted to descend of its own gravity. By this arrangement the tackle block will always be automatically released as the carrier is broughtinto locking engagement with said retaining bracket 2. When, however, it is desirous to release the hoisting rope, while the carrier is upon either side of the retaining bracket, the required movement is communicated to said clamping cam 19 from the operating cord 15 as stated through said lever 16, lug 17, buffing bar 12, arm 18, arm 22, and vertically moving bar 14, link 14 pivotal connections 15 and 16 whereby said cam is raised and thrown out of contact with said hoisting rope when the tackle block is permitted to descend.

As in my previous carrier the upper end of the catch 6 is provided with a recess 25 for the reception of the latch 20 and said latch and catch are both pivotally supported from the same bolt 10 between the lugs 21., 21, which lugs 21 are formed integrally with the walls of the carrier frame 5, while the lower arm 22 of said latch is brought above the arm 18 of the catch, whereby when the arm 18 is raised by the action of the bufiing bar it will contact and raise said arm 22 and said catch 6 and latch 20 will be simultaneously actuated. The vertically moving bar 14 is provided With a longitudinal slot 26 for the reception of the stationary bolt 13 which bolt is supported at its respective ends in the vertical walls of the carrier frame, said slots being formed to permit of the vertical movement of said bar. The buffing bar 12 is also provided with a longitudinal slot 27, to permit of its vertical movement past said bolt 13.

It will be understood that while the catch 6 is being raised by contact with the angular walls 11 of the bracket preparatory to dropping into the recess 7, the arm 21 of the latch 20 is simultaneously raised or thrown back by contact with such bearings, whereby the clamp 19 will be thrown out of engagement with the hoisting rope. Thus the same movement of the carrier which locks it in engagement with the track also simultaneously disengages the clamp from the hoisting rope and permits the tackle block to descend.

The interior connecting collar 28 is formed integrally with the carriage 5, while the exterior collar 29 is formed integrally with the is adapted to engage the opposite loop of the sling.

Referring to Fig. the angular bearings 11 of the bracket 2 are connected together by the plate and said bracket is connected with the track by the bolts 36, 36. The plate 35 serves as a contact bearing for the arm 21 of the latch and prevents said arm from dropping into the recess 7 while the catch 6 is permitted to drop into its locking position in said recess.

It will be understood that the other parts of the device shown, but not specifically described are constructed and adapted to operate substantially as shown and described in my said previous patent.

Having thus described my invention what I claim as newand desire to secure by Letters Patent is,
