Specification of Letters Patent.

Patented Sept. 2,1913.

Application filed June 20, 1910. Serial No. 567,969.

no all wlw/nt it may concer/n.'

Be it known that I, Emslm Goonnm. TnoMAs, citizen of the United States, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvements in Vagons, of which the following is a specification.

My invention relates to a vehicle running gear of the type shown in my Patent No. 624,264, dated May 2, 1899, and more particularly to that class of gears where the wheels are pivotally mounted upon the axles in such a manner that the axles remain stationary and the vehicle is steered by swiveling the wheel spindles upon the axle ends which is effected by suitable mechanism attached thereto, and which operates all of said spindles simultaneously.

The objects of my invention are to produce a noval, cheap, durable and effective means for guiding the swing of said spindles and for bracing and guiding the operating levers by which the spindles are swiveled or operated.

With these and other objects in view my invention consists in certain novel construction and combination of parts as will hereinafter be fully described, and claimed, in this specification and illustrated in the accompanying drawings, which form a part of this application, and in which like figures of reference refer to corresponding parts in all the views; but it is fully understood that while I have described my invention as herewith illustrated, I do not conne myself to the exact construction as shown, as slight changes may be made in the construction and combination of parts withoutdeparting from the spirit of the invention.

In the drawings :-Figure 1, is a plan view of an axle and spindles, showing my novel construction. Fig. 2, is a front elen vation of the same. Fig. 3 is an end view of one of the spindles. Fig. 4, is a detail view of the guide or bracket in perspective.

Referring to the drawings, l, indicates the axle to the ends of which are pivoted the spindles 2, by the pins 3. Said spindles being hollow and having vertical side walls converging toward the front of the spindle between which are pivoted the ends of the axle 1, on the pin 3 and said spindles are also provided with the parallel flanges 5, which are adapted to slide upon the upper and lower surfaces of the axle and serve as a guide for the swivel, while the perpendicular faces of the flanges are in the form of an are of al circle or segment Struck from the pivot pin 3, as a center, and are designed to slide in the race, 7 of the guide and supporting bracket 8. Said bracket S, is iutended to embrace the axle 1, and be held thereon by the lugs 9, and bolts 10, while the race 7 is circular in form to correspond to that of the flanges 5, which are intended to slide therein, said race serving to support and guide them.

The operating levers 11, are connected at their rear ends to the dust caps 12, which are secured to the spindles 2, and said levers 11, at their forward ends are connected to the connecting-rods 13, which are pivoted to the ends of the wagon pole 14, and by which they are operated in the usual way. It may also here be remarked that the above described mechanism applies to all four of the spindles and constitutes what is known as a short turn gear.

From the foregoing description it is believed that the operation of this device will be fully understood without further detailed description.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a swivel spindle running gear for vehicles, comprising axles, wheel-spindles pivoted upon said axles, said wheel-spindles formed with a longitudinal orifice in the body thereof, parallel bearing lugs extending from the rear end of said wheel-spindles and integral therewith, a bearing and guide bracket formed with a box-shaped body having depending securing lugs, and curved race and guide arms integral with and extending from the rear end of said bracket and adapted to receive the lugs of said spindles, means for protecting said mechanism and means for swiveling said spindles upon the axles.

2. In a short turn vehicle gear of the class described, comprising axles, wheel-spindles formed with longitudinal tapered orifices embracing the ends of said axles and pivoted thereon, parallel bearing lugs formed with curved faces projecting from the rear of said spindles and integral therewith, bearing brackets formed with a body portion provided with lugs adapted to embrace and be secured upon said axles, supporting arms extending from the end of said brackets and integral therewith, guide races formed in said arms and adapted to receive the lugs of and adjacent to said spindles, bearing lugs l5 said spindles, circular split dust caps secured to said spindles and adapted to cover and protect said mechanism, operating levers 'having their ends secured to said dust caps for the purpose of svviveling said spindles, connecting-rods having one of their ends pivoted to said levers and their other ends pivoted to the reach of said gear.

8. In a vehicle gear of the class described, comprising Wheel-spindles pivo-ted upon and near the'ends of the axles, supporting brackets formed with curved guide races and secured upon said axles near the ends thereof formed upon the rear end of said spindles,

and adapted to engage and slide Within said race, levers secured to and projecting from the rear end. of and at right angles to said spindles, and mechanism to operate the same from the tongue of said gear for the purposes set fort In testimony whereof I aiiX my signature vin presence of two Witnesses.
