JOHN P. BEOKENBAUGH, OF SPRINGFIELD, ILLINOIS.

IMPRo'vEMENT IN DRAFT-EQUALIZERS.

vSpecification forming part of *Letters Patent No, 144,052, dated October 22,1873; application filed i May 26, w73.

To all whom it may concern: V

Be it known that I, JOHN l". BEcKENBAUe-H, of Springfield, in the county of Sangainon and State of Illinois, have invented awnew and valuable Improvement in Three-Horse Equalizers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this speciiication, and to the letters and gures of reference marked thereon.

Figure l of the drawings is a representation of a front view of my device. Fig. 2 is a top View of the same.

This invention has relation to three-horse equalizing attachments; and it consists in the construction and novel arrangement of the angle-plates to which the pulley -journals are fixed, and the partition-plate between each set of middle pulleys, one above the other, in connection with the whiflletree and attachmentchains, as hereinafter more fully described.

In the accompanying drawings, the letter A designates the whiflietree, tapered on each side toward each end, so that it will be thickest in its middle portion. The front face of the whiffletree is plane, preferably, so that the angleplates will not require to be extended therefrom to any considerable distance to bring the pulleys in line with each other. dicate the angle-plates, which are attached, by their rear arms a, to the upper and lower surfaces vof the whiffletree, there being four of these plates for each surface, arranged at equal distances apart horizontally. The corresponding plates B, at each end of the whiffletree, constitute a support for the end -pulleys O, the inner arm of each plate being slightly twisted or bent to correspond with the taper of the tree, and to bring those portions of the plates which are in contact with the pulley parallel with each other, so that the chain will not be liable to be caught between the pulley and plate. Vertical pivotpins e connect these plates. The corresponding plates B', in the middle portion of the whiftletree, where it is thickest, are far enough apart for the reception of two pulleys, D, one above the other, on the same axial pin e, but separated from each other by a division-plate,

l E, secured by inserting its rear end into a horizontal recess in the middle line of the plane front wall of the whiiletree. F indicates the attachment-chains, by which the tracetugs are connected withthe whifiietree. These attachment-chains are three in number, and are rove about the pulleys in the following manner, the chains and horses being, respectively, numbered l, 2, and 3 from the left: Chain No. 1 is passed around the end pulley C at the left and one of the next inner set of pulleys D. Chain No. 2 is carried around the other pulley D of this set and the corresponding pulley D of the next set. Chain No. 3 is passed around the other pulley D of this set and the endpulley O at the right. In gearing up, horselvvNo. l is attached, by the draft-tugs, to the leftjends of chains Nos. l and 2; horse No. 2 tothe right and left ends, respectively, ofchains Nos. l and 3 and horse No. 3 to the right ends of chains Nos.. 2 and 3.

The angleplates, being attached by the oblique branches to the whiflietree, are not apt to become loose by the lateral pulling of the horses, as, whether they pull to the right or left, the direction of the strain Will be mainly in line with the opposite branch of the plate.

The partition-plate E extends from the whifiletree outward, and is perforated for the passage of the pulley journals. It is not apt to get out of place or obstruct in any way the working of the chains.

I am aware a three-horse equalizer with single end pulleys, sets of superposed inner pulleys, and attachment-chains, are not new, and therefore I do not claim such invention, broadly; `but What I claim as new, and desire to secure by Letters Patent, is

In a three-horse equalizer, the angle-plates B B', having oblique branches attached to the whifdetree in the direction of lateral strain on each side, the chain-pulleys and the journalpins c passing through the angular portion of the plates B B', with or without the division plates E, said part being constructed, coinbined, and arranged as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. t

JOHN P. BECKENBAUGH.
