IMPROVEMENT IN RUNNING-GEARS FOR VIEHICLES.

Specification forming part of Letters Patent No. 1541,65?, dated September 1, 1874; application filed June 27, 1874.

To all whom it may concern:

Be it known that I, WILLIAM A. EHRGOTT, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Axle and Skein; and I do hereby declare that the upper inner end will curve upward, and press against the outer side of the hounds ot' the wagon-tongue, and thev lower inner end under the axle to a vertical line with the inner side of the hounds, so that thel bolts which pass through the bolster-hounds and axle for tying them together will also pass through the lower extension of the skein or thimble, the whole being soconstructed, combined, and arranged with relation to each other, as to impart strength and firmness, and 'brace the several parts. l

. To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

1n the accompanying drawings, which'forrn part of my specitication, Figure l 'is a top view of my improvement in axle and skein for wagons. Fig. 2 isp. longitudinal and vertical section of the same. I

In the accompanying drawings, A represent-s the axle,whichl is constructed of wood, and is of. the usual form, excepting the recesses for hounds. The hounds k for the wagon--tongue are of ordinary construction, except the curved recess inthe outer side for the reception of the upper and curved extension c of the axle-skein. The' axle-skein B is constructed of wrought-iron plate cut to a suitable pattern, then bent, and the joint welded together by the forging process. It may be cast of steel or cast of Missouri pig iron,7

and subsequently converted into steel. The curved extension e forms a brace for the hounds k, and by means of the clip f, and its screw-nuts g, the skein B can be drawn on a horizontal line firmly home on the coniformed points 11. of the axle A, and `rmly against and into the recess in the sides of the `hounds k, thereby securely bracing them in` their recesses in the axle A. 'lhe lower exltensione of the skein B projects back on the under side .of` the axle A to a vertical line with the inner side of the hounds k, so that the bolt i, which passes through the bolster h and a'xle A, shall also pass through the extension o of the skein B, thereby iirmly securing these several parts together, and causing them lto brace each other, whereby all jarring action and strain of the runnin g-gear of the wagon shall be distributed through the several parts. The form and extent ol' the extension of the skein B gives its strength at the point where the skein usually breaks, viz., between the line y and outer side of the houndsjk. The skein-B isprovided with the usual flange() for the innereud of the box l to press against. D represents screw-threads for the nut A',

shown in Fig. 1. The skein is furnished with an opening, m, for a linchpin, indicated by the dotted lines x. The openings m and linchpin af are only used in case of the loss of the nut A. The advantage of the opening and Witnesses:
