To all whom it may concern:

Beit known that I, ROLLAND S. Tno'rr, a citizen of the United States, residing at the city and county of Denver and State of @010- rado, have invented certain new and useful Improvements in Cantaliver-Spring Mountings, of which the following is a specification.

My'invention relates to an improvement in cantaliver spring mountings, and the object is to provide a mounting for cantaliver springs that will permit horizontal movement of the axle to which, the spring is connec'ted' without giving the axle a vertical movement as part of the horizontal action; and further to provide means for a resilient drive through the cantaliver spring; and stillfurther to provide means, to maintain the axle at right-angles to the line of draft. With these objects in view, my invention com rises a cantaliver spring supported at onep'oint u on an axle and having connection with the frame of the vehicle at two other" 'oints in such a manner that the axle end the spring may be made to move in a nearly horizontal path as thesprings are swung back or, forward with respect to the franie'y" and it further consists in details of construction which will be hereinafter described and pointed out in the claims.

of the arms 5, 5, which latter are secured rigidly:- upon.- the cross-shaft 6, which is mounted to turn in the frame A, and extends to the other side where the parts are duplicated, the cross-shaft being the means illustrated for keeping the axle square.

The arms 5 are of greater length than the lmks 3. By proper proportiomng of these arms and links, the tilt of the sprm s, their camber, and the position of the midd e pivot, the axle end of the spring may be made to move 1n a nearly horizontal path as the springs are swung back or forward on their links and arms- In the construction shown in Fig. 4:, the same general proportions are mamtained, but the relation of arts is reversed, that is to say the cross-she t 6 for keeping the axle square is at the end, and has secured thereto short arms 3' in this instance, instead of the links 3 of the former construction. In this form, the longer links 5 are pivotally connected with the cantaliver spring at their upper ends as at 4:, at an intermedlate point, and pivotally connected to the frame A at their lower ends.

Figs. 5 and 6 correspond with the construction just described, except in this instance the arms 5 secured to the cross-shaft (i extend downwardly to the springs 2, thus providing for a frame which is mounted high above the axle, the links 3 extending in a corresponding direction from the frame to which they are pivoted. The only difierence between the constructions shown in Figs. 5 and 6 is that in Fig. 6 the cross-shaft 6 is connected through arms 3 to the end of the spring, and instead of the longer arms 5*, links of corresponding length are pivotally connected with the frame and extend downwardly therefrom where they are'pivotally connected with the spring at a point at or preferably somewhat away from center, as at 8.

Figs. 7 and 8 illustrate the same principle, in. which in lieu of the arms or links extendin from the frame to an intermediate part 0 the spring, rollers 9, 9, are connected to the frame and embrace the opposite sides of the spring Fig. 7 showing a low mounted frame, and F 7, the upper surface of the spring wit which the roller comes in contact is convex as at and in Fig. 8, it is concaved as at 311, the rollers in both instances emloracing the opposite parallel surfaces.
