JAMES M. BROMLEY, OF PLATTSBURG, NEW YORK, ASSIGNOR TO-WILLIAM E. SMITH, OF SAME PLACE.
VEHICLE-SPRING.
SPECIFICATION forming part of Letters Patent No. 304,606, dated September 2, 1884.
Application filed June 11, 1884.
To all whom it 711 501; concern.-
Be it known that I, JAMES M. BROMLEY, a citizen of the United States, residing at Plattsburg, in the county of Clinton and State of 5 New York, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a specification, reference being had therein to the accompanying drawings.
Figure 1 is a side view of the spring in position; Fig. 2, a side view of the untempered plate or leaf; Fig. 3, a top view of the spring.
This invention relates to improvements in vehicle-springs; and it consists in the construotion hereinafter set forth.
In the annexed drawings, the letter A represents a wagonbody, and B an axle, in connection with which the use of .my inventionis displayed. With a vehicle, four of these springs are to be used, two on each side, connected to the body and axles. In the drawings only one spring is shown. The spring 0 consists of a plate, leaf, or strip, a, of untempered ductile iron or steel, and one or more superimposed lcaves, c, of tempered or elastic metal. The strip a is provided near its axle end (1 with a guide-loop or check, cl. Through this loop passes loosely the free end 6 of the spring leaves a. The other ends of the strip 0 and leaves a are secured together rigidly. The spring thus constructed is put in place by rigidly securing the inner or body ends of the strips to the body, as at a, and the outer or axle ends of the'strip c to the axle by the or- 5 dinary shackle, b, as shown in the drawings.
(N0 model.)
The strip 0 of untempered metal forms the connection between the body and axle and moves on its shackle b. The tempered leaves 0 take up the motion of thebody and give an elasticity to the yield. A spring thus constructed 4o possesses important features. pered strip takes the place of the thoroughbrace-such as is shown in reissued United States Patent No. 9,827-giving more rigidity to the spring, preventing any "twist, roll, or 45 side swing, and allowing a perfectly-free recoil or upward motion within the limit of the checkloop.
Having described my invention,what I claim The untem- 1. A vehicle-spring consisting of astrip ol' untempered and a strip of tempered metal, as set forth.
2. A spring in which the upper leaf or leaves are of tempered metal resting on a lower 5 5 leaf of untempered metal, as set forth.
3. A spring the lower half of which is untempered and ductile, as set forth.
4. A spring in which the lower or main leaf acts merely as a support to the spring proper, 60 at the same time allowing a perfectly free recoil or upward motion within the limits of a check-loop, as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES M. BROMLEY.
