SPECIFICATION forming part of Letters Patent No. 295,177, dated March 18, 1884. Application filed August 10, 1883. (X0 model.) I

2"0 all whom it'mrq concern.-

Be it known that I, RUDOLPH S. HUNZEKER, of Pittshnrg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Vehicle-Springs; and I do hereby declare thefollowingto be a full, clear, and exact description thereofi,

My invention relates to that class of vehiclesprings wherein spirals are combined with saddles, suspension-brackets, and like devices for sustaining the bed or body of the vehicle.

I am aware that spiral springs have. been ment to the bodies of vehicles, in some and most cases the spring being interposed between the bearing and weight to be supported and operated by compressiomand in other: cases the weight has been suspended byspiral springs mounted in a hollow standard, or spiral springs extending in a line nearly horizontal between the body of the vehicle and end and side bars. Both of these forms are inefficient, as they either are insecureainstable, and liable to weaken and destroy the springs, or fail to form a firm. perfect, and direct spring action between the frame or body and My devices ditt'erfrom these in thatadirect, firm, and posi tive action is given to the spring. which is not materially weakened by use. This is owing to the position of the springs and the manner of attaching them to the vehicle.

I will'now describe my invention, so that others skilled in the art may manufacture and use thesame, reference being bad to the accompan ying drawings, forming apart ofthis specification, in which Figure l is a vertical cross-section through one of the side bars, showing the spiral spring connecting the end of the elliptical spring to the side bar. Fig. 2 is a detached view of the spiral springs, the plate for securing the springs to the side-bar, and the bolt for securing the end of elliptical spring to the spiralsprings. Fig. 3 is a detached plauview of the plate. Fig. 4 is a plan view of the frame of a vehicle having elliptical springs, showing my improvement. Fig. 5 is a vertical showing my improved springs adapted to not i between the body of the wagon and the bolster.

Fig. 6 is a side elevation of a portion of the bolster. Fig. 7 is a detached view of a portion of the securingplate.

Like letters of reference indicate like parts wherever they occur.

In the drawings, A representsthc top bar of the vehicle mounted on the front axle. B represents the rear axle, and 0 represents the side bars extending from the rear axle to the head bar. The body of the vehicle rests on elliptical springs D, which extend from one side bar to the other, and the ends of which are secured thereto.

Instead of securing the ends of the elliptical springs D directly to the side bars, I secure them to the ends of a double spiral spring, E F,which extends vertically down from the side bars. This spiral spring consists ot'two spirals, E F, extcndiugparallel to each other, having loops or eyes E F at their ends, and connected by a straight bar extending horizontally at right angles to the direction of the spiral portion of the spring. This spring is secured to the lower or under side of the side bars a, by

a plate, G,i n the face of which is a groove for the reception of the bar portion of the spring E F and a clip, H, which encircles the upper side of the side bars, and the ends of which pass through holes G in the plate G and are secured on the under side of the plate by the nuts H, the ends of the clip being threaded, the bar F. of the spring E F being held between the lower side of the side bar and the groove in the upper face of the plate G. The ends of the elliptical springs D are pivotally attached to the ends of the spirals E F by a bolt, I, passing through the eyes E F and an eye, D, formed at the end of the elliptical springs. This bolt I is secured by ahead at one end and a not at the other, or by upsetting the ends of the bolt after it is placed in position. The elliptical springs D may be of any of the forms I now in general use.

bolster of awagon or vehicle not provided with other springs. In this modification the same form of spiral spring is employed, excepting that it is stronger and heavier, the purpose being to support the entire weight,

l instead of acting to relieve a particular part.

Bolted or otherwise secured to the underside of the body of the wagon is a bracket, JK, the arms of which extend vertically down on each side of the bolster L. The bar E extends across and rests on the upper side of the bolster L and the plate M, in the face of which is a groove, M, which fits under the bar E. This plate is secured to the upper side of the bolster by screws or bolts passing through holes in the plate. The spirals E F extend downward vertically on each side of the bol ster L, parallel with and inside of the arms J Kof the bracket.

Passing through eyes J K in the ends of the arms of the bracket, and through the eyes E Fof the spirals, is a belt, I, already described. The body N of the wagon is thus held up from the bolster, being supported by the bracket and suspended from the bolster by the spiral springs E F, while the springs are prevented from being broken or injured by too heavy a the direct jars and strain, and a cheap and durable spring is afforded for heavy farm and other wagons and vehicles.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,'is

1. Aspring having two or more spirals parallel with each other and united by a crosspiece at their upper ends, the spirals being arranged to act by extension in lines on or approximating the same vertical plane, substantially as and for the purpose specified.

2. In a wagon or other vehicle, a double spiral spring having two or more spiralsjoined or connected at their upper ends, the spirals acting by extension, the body of the vehicle being suspended from the lower ends thereof, substantially as and for the purpose specified.

8. In avehicle having side bars and springs extending transversely between the same, the

COll'lblllit'tlOlJfiVlth the side bars and transverse springs,of interposed extensible spiral springs arranged to suspend the transverse springs 5 RUDOLPH S. HUNZEKER.
