.HAY-LOADER.

SPECIFICATION forming part of Letters Patent No. 837.811,dated March 16, 1886.

Application tiled Ma 1, 18%2.

To all whom it may concern:

Be itknown that we, J ACOB BRIMER, BEN- JAMIN F. BRIMER, WILLIAM M. BRIMER, and JACOB B. BRIMER, all citizens of the United States, residing in Itichland Centre, county of Richland, and State of Wisconsin, have invented certain new and useful Improvements in Hay-Loaders, of which the following is a specification.

This invention relates to improvements in hay-loaders in which the hay is elevated from the ground and discharged upon a wagon by endless carriers consisting of chains and teeth mounted upon a wheeled frame.

The object of this invention is to promote the effectiveness and simplicity in the construction of hay-loading machines by devices and combination of devices, hereinafter described, and particularly pointed out in the 20 claims,and in the accompanying drawings, in

which-- Figure 1 represents a longitudinal section of a hay-loader embodying our invention; Fig. 2, a detail side elevation looking at the ends of one of the elevator-slats, showing the attachment of the bearing of the slat to the drive-chain and the means for limiting the pivotal movement of the slat in its bearing; Fig. 3, a detail top plan view of portions of the drive-chain, toothed slat, and runningboard, showing also a traveling block and its position upon the running-board; Fig. 4, a side elevation of the same, showing the means of securing the slat to its pivot-casting and a section of the bearing. Figs. 5 and 6 show the different positions of the teeth and block as they pass over and then under the elevator to drop their load; and Fig. 7 a detail sectional side elevation, showing the traveling o block in its operative position upon the running-board and the manner of securing the running-blocks, slats, and teeth together.

Similar letters of reference indicate the same parts in the several figures of the draw- 5 ingS.

A represents the supporting-wheels, the axles of which are bolted or otherwise secured to the frame 13, which is coupled to the wagon in the usual manner.

5o Pivotally secured in the usual manner by plates or hinges to the rear end of the frame B is the elevator G, which is adjusted to the desired heightupon a standard, 0, secured to the frame B by any suitable means, not necessary to be shown, which may consist of a pivoted link upon the elevator and ratchet-teeth upon the standard.

Journaled in the rear ends of the side pieces of the frame B or in bracket-bearings upon their under edges is a shaft, a, carrying near each extremity a sprocket-wheel, 1). Similar but smaller sprocket-wheels, c, are journaled in suitable brackets or other bearings at the upper end of the elevator. Said sprocketwheels carry an endless drive chain, (1, at each inner side of the elevator. which chains in turn support a series ol"parallel slats, c, carrying the elevating-teeth f, the means of attaching which will be more fully hereinafter described. The upper sprocket-wheels, c, are so arranged: with reference to running-boards,(uot shown.) upon which the upper parts of the chains rest, or rather are supported when in operation as well as when idle, that the top portions of these sprocketwheels are substantially in a plane with the ruuningboards; hence the chains are substantially in a straight line when loaded, and afford less resistance to the for. ward revolutions of the sprocket-wheels than if these wheels were in a plane above the line of travel of the chains.

Slats e are bolted by the bolts m to. cast pivots f, which at the point of fastening of the slats are provided with side flanges, g, embracing the edges of the slats, and not only effect- 'ually preventing the lateral displacement of the slats, but a lateral strain upon the bolts securing the slats. The pivots f are rectangularin cross-section at their.bearing,as clearly shown in Fig. 2, and are journaled in bearings 0 h, suitably slotted, as shown in Fig. 4, for'attachment to the drive-chains, and provided with opposing internal lugs or projections,,];i h, V-shaped in cross-section, which serve as stops tolimit the pivotal movement of the slats, for it will be understood that with these lugs the flattened pivot f can make only a half-turn.

Owing to the effectiveness and durability of the stop mechanism above described, it is an important feature of our invention; but while it may be a very important and useful auxil- F iary to the traveling blocks,tobe described, in limiting the pivotal movement of the slats, it

should be understood that they are not absolutely and at all times necessary for the effective operation of the traveling blocks in swinging the carrier-teeth to disengage them from their load, but it is nevertheless admitted that it does cause a more positive and quicker operation ofthe traveling blocks to that end, and in this respect would be a very valuable substitute for other devices now in use and in tended to operate for the same purpose,though not successfully.

Extending along the center of the width of the elevator is a running-board, 2', which supports the traveling blocks 70 k,secured at right angles to and at the center of length of the elevator-slats. The running'board supports the traveling blocks only during the forward movement of the blocks on the elevator, said blocks swinging clear of the board as soon as they have passed the upper end of the board, which swinging movement is occasioned by the gravity of the blocks and the teeth and the pressure of the hay upon the teeth. This permits a swinging movement of the slats at the proper moment to rcleasethe teeth from their load.

The traveling blocks are shown secured to the slats by the bolts m. passing through the slats and blocks and having nuts on their upper ends; but while this isa convenient means, they may be secured in any desired manner. These blocks are concave on their under sides and are provided at each extremity with antiiriction rollers Z Z, to facilitate their traveling.

As shown in the accompanying drawings, there is a single traveling block to each slat; but there may be more. if desired-in fact, a traveling block under every carrier-tooth f, though this is hardly necessary.

It will be observed that the carrier-teeth have a forward curve in their operative position, in order that they may have a better hold upon the load they are supporting, and that when in this position the traveling blocks are rolling on the running-board, but that as soon as the rear end of the traveling block passes beyond the upper end of the running board this rear end of the block first drops down, "as indicated in Fig. 6, when the forward end of the block is carried under, as indicated in Fig. 5, (when taken in connection with Fig. 6.) and by' this means the carrier-tooth is'first drawn back and freed from its load before it assumes the position shown in Fig. 5, under the running-board. Of course, to attain this movement of the traveling blocks the sprocket-wheels 0 are at a point beyond the end of prevented by limiting the downward movement of their rear ends.

The rake-head n is supported by the inclincd standards 0 and vertical standards 12, secured to the frame B, in the usual manner, so that it may have a pivotal movement up and down, but is also provided with a bar, q. upon which is a weight, r, adjustable along this bar, so that the downward pressure of the weight upon the rake-head may be increased or diminished at will, and by this means the rake be made more elastic than if a weight were not used.

For the purpose of preventing the hay clogging between the rake and elevator-teeth, we

secure to the rake-head teeth or guards s,

which have an opposite curve to the raketeeth and extend first below the shanks of the same, with their free ends projecting between the rake-teeth in such a manner that a yielding pressure is constantly exerted upon the hay as it is loaded on the elevator-teeth, keeping the hay away from the rake-head and pressing it against the elevator-teeth, .thus causing them to take afirin hold upon the hay and at the same time slightly compressing the hay and preventing its flying about.

We do not of course confine ourselves to the exact construction shown of the guards, for our invention includes a yielding guard, so constructed and arranged as to perform the functions just ascribed to it.

Having described our invention, what we claim, and desire to secure by Letters Patent,

1. The combination, with the endlesschains orbelts and toothed slats pivoted thereto, of a running-board intermediate the extremities of the slats, and traveling blocks provided at their extremities with wheels supported 'on said board, said blocks being concaved on their under sides and adapted to support the teeth in an erect position and to swing down after leaving the board and permit the swingas described.

2. In a' hay-loader elevator, the combina-.

tion, with the chain belts and the slats, of bearings connected with the drive-chains and provided with internal V-shaped stops, said slats having flattened pivots engaging with the bearings, substantially as described. v

3. The combination of the endless belts, the bearings having the V-shaped stops, the slats pivoted in said bearings and engaging with said stops, the running-board, and traveling blocks and teeth secured to the slats, said blocks mountedon rollers and supporting the teeth in an-erect position above the runningboard, substantially as described.
