Application filed July 9, 1917.

To all ur/m/lt it may roizcern:

l lo it known that l, VVAL'rl-n: l3. lninin'r'r, a citizen of the lhiited t tates, residing at .wlason ity, in the county of lerro Gordo and h tale of lowa, have invented certain new and useful lniprovenients in Vehicle Axles: and l do hereby declare the following to be a full. clear, and exact description of tie invention. sucl as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the front or steering axles of tractors or motor cars; and it consists in the novel construction and munbination of the parts hereinafter fully described and claimed.

ln the drawings, l igure 1 is a front view of a steering axle constructed according to this invention. Fig. 2 is a plan "view of the axle. Fig. an end view of the axle. Fig. *l is a crossecction through the axle, taken on the line a:-a2 in Fig. 2.

The main frame 2 of the vehicle or tractor is of any ap 'n'oved construction. Two similar angle-shaped brackets 3 are provided, and are secured parallel to each other and crosswise of the front end portion of the frame 2. The upper ends -'1 of these brackets are turned so that they lie flat against the sides of the frame, and they are secured to it by liYets 5. The apices of the brackets project donuiwardly of the frame, and 6 is a block provided with laterally projecting trunnions T which are pivoted in the lower end portions of the brackets 3 on the longitudinal axis of the tractor.

.J tn axle frame is provided, and it comprises parallel. upper and lower bars 8 and 9, suitably connected together by two vertical distance pieces 10 arranged at a, little distance apart and one on each side of the center of the block 6, and a brace or braces 12 secured diagonally between the middle and the end portions of the bars 8 and 9.

A vertical pin 1 1 is secured to the bars 8 and 9 in the space between the two distance pieces 10. and the block 6 is slidable vertically on the pin 1-1. A helical spring 15 is arranged to encircle the pin 14 in the space between the two distance pieces. and between the block 6 and the lower bar 9 of the axle frame. The weight of the front end portion, of the main frame "3, and the Specification of Letters Patent.

parts carried by it, rests on this spring 1:") which prevents the jolts due to the roughness of the road from being transmitted to an injurious extent to the main franie.

Bearing blocks 16 are pivoted. by vertical pins 17 between the upper and lower bars 8 and 9, at the end portions of the axle frame. The bearings 18 of these'bloclcs are arranged to one side of, and pcrferably in front of, the pins 17. Axle spindles 20 are provided and are carried by the bearings '18, and front road wheels 21 of any approved construction are journaled on the spindles 20. The bearing blocks have forwardly projecting arms 22, and 9A: is a com pling-rod pivoted between the free end portions of the arms 22. One of the axle spindles has a cranked extension 25, and 26 is a portion of the steering-rod which is pivoted to the extension 25. The rod 26 is operated. by any approved means, and it operates the two steering road wheels simultaneously. Suitable braces 27 are also provided, and are connected to a crossbar 28 on the main frame and to the axle fame, so as to permit the main frame to move vertically under the control. of the spring 15, and so as to hold the axle frame crosswise of the main frame.

These braces 27 are arranged and secured in any approved way, and they are prefer ably diverging spring braces, and are inclined down\vardl and forwardly, and have their front ends secured to the lower bar 9 of the axle frame.

A steering axle constructed in this manner inexpensive to manufacture, and it is relatively light and strong, and is not liable to get out of order.

What I claim is:

1. The combination, with a main frame, and a pair of brackets secured crosswise thereof and projecting downwardly; of a block provided with trunnions which are pivoted in the said brackets, an axle f'ame comprising upper and lower bars suitably braced together, means for holding the axle frame crosswise of the main frame, a pin secured to the middle parts of the said bars and slidable vertically in a hole in the said block, a helical spring arranged between the said block and the lower bar of the axle frame, and axle spindles for the road wheels connected t the end portions of the axle frame,

2. The combination, with a main frame,

and a pair of brackets secured crosswise thereof and projecting dcmnwzu'dly; of a block provided with trunnione which are pivoted in the said brackets, an axle i'rnme comprising upper and lo er hare snitnhlv braced together, means for holding the t'rnnie crosswise of the main frame, u pin secured to the middle parts of the said hers and slideble vertically in a hole in the said block, a helical spring arranged between the said block and the lower hair of the axle irunie, bearing blocks pivoted by vertical pins between the end portions oi? the bars of the axle frame and provided with been ings arranged to one side of their pivot pins and axle spindles for the road wheels projecting from the said hearings.

In testimony whereof I have e'liiX-ed my signature.
