(IN whom it may concern:

Be it known that I, BENJAMIN A. GRAMM, a citizen of the United States, residing at Bowling Green, in the countyof Wood and State of Ohio, have invented certain new and useful Improvements in End Mountings for Vehicle-Springs, of'which the following a specification, reference being had to; the accompanying drawings. a i

This invention relates to improvements in mountings for the ends of road-vehiclc springs; and an object of this invention is to provide an end-mounting for a vehiclespring which will relieve the spring of stress and which will prevent accidents in the case of the breakage of the parts. i In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure 1 is an elevation of so much of a selfpropelled road-vehicle as is necessary to illustrate this invention; Fig. 2 is a" rear elevation of the spring-mounting, the sidebar of the chassis being shown in section; Fig. 3 is a side elevation of'what is shown in Fig. 2; and Fig. 4 is a section on the line AA of Fig. 3.

The vehicle-wheel a is mounted on its axle Z. between which and the side-bar'or sidebeam 0 of the chassis is interposed the vehicle-spring d. One end 6 of the latter is mounted in a hanger f carried by the side-- bar 0, while the other end of the vehiclespring (Z is formed with an eye through which passes a pin 9 upon which are mounted free to turn the rollers it, one on each side of the end of the spring at. These rollers are held on the pin gvby the nuts 2'. To the web and lower flange of the sidebeam 0 is riveted the hanger-plateQy' from.

which project downwardly the legs 70 to which are bolted the guard-bars m. The latter are arranged just below the rollers /l and form with the hanger-plate j and its legs-1c a sort of cage or box in which the end of the spring is held, in case the pin 9 should shear. It is obvious that the stress on the pin g is much reduced by reason of the roller-mounting and likewise the liability to such shearing or breakage. A hard steel wear-plate n is fastened to the lower face of the horizontal part of the hanger-plate y. Should the pin 9 shear or break, the spring will be held by its end-mounting shown in Figs. 2, 3 and '4 underneath the v hicle, thereby avoiding serious accidents.

I claim:

The combination with a frame of a vehicle; of a hanger-platefastened thereto and formed at each side with a pair of legs which project from below the bottom of said ianger-plate; a pair of lengthwise-extending guard-bars which are fastened to said legs and each of which connects a pair of said legs; and a vehicle spring one end of which lies below said hangerplate and passes between two of said legs at the inner end of said hanger plate and which is provided with laterally-extending projections that lie between said'guardbars and hangerplate.

In testimony whereof I hereunto set my hand at Bowling Green, Ohio, this 11th day of March, 1910, in the presence of the two undersigned witnesses.

BENJAMIN GRAMM.
