J. R. LOCKE.
Carriage Spring.
No. 82.726. Patented Oct. 6, 1868.
// /mwm fag/v (f UNITED STATES PATENT QFFICE.
JOSIAH R. LOCKE, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN CARRIAGE-SPRING.
Specification forming part of Letters Patent No. 82,726, dated October 6, 1868.
To all whom it may concern Be it known that I, J osiAH R. LOCKE, of the city and county of San Francisco, State of California, have invented an Improved Carriage-Sprin g and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.
My invention consists in the employment of two springs at each side of the carriage, crossing each other diagonally and bolted to the frame, the front springs being continuous and bent around the bolster and attached to the reaches.
The rear springs are of the C form, and are also attached to the reaches and connected to the side springs by shackles. of the frame is provided with a reach, which is fastened to the bolster by a strap, beneath which is placed a cushion or spring of elastic material, which is held by a rod extending back to the rear side springs, to which it is attached.
To more fully illustrate and describe my invention, reference is had to the accompanying drawings, and letters marked thereon, of which Figure l is a side sectional elevation. Fig. 2 is a plan'with the bed removed. Fig. 3 is an enlarged View of the rubber spring.
A A represent the two outside reaches, and B the center reach. C is the bolster, and D the axle-bed. The front springs, E E, are fastened to the ends of the outside reaches and bent around the bolster and carried back to near the center of the frame'F, to which they are attached. Side springs G G are also attached to the frame, reaching near the front end and crossing the springs E E in a diagonal manner, extending to the rear part of the wagon, where they are connected to other or C springs I by shackles H. The C-springs are bent around the axle-bed, and attached to the reaches in the same manner as the front springs.
The middle reach, B, is connected to the axle- The center bed and bolster, and is cut away back of the bolster to form a box, J, over which is placed a strap, J, which is bolted to the reach and bolster. In this box is placed an elastic packing or spring, K. I think india-rubber the best material to use for this purpose. Through the opening in front of the spring is a bracerod, L L, which rests against the spring, and is carried back in a diagonal direction to the rear end of the side springs G G, to which it is bolted.
By this means, especially where springs made of wood are used, an easy and elastic.
motion is given to the carriage, and the rigidity of the wooden springs overcome by the shackle-connection to the C-springs and the rod-attachment to the side springs G G, pass in g around the end of the rubber spring back of the bolster, and as the weight comes upon the carriage the brace-rods are distended back, drawing against the rubber spring, and a yielding motion is always had. Also, the dif ficulty of spreading is overcome, as when the C or continuous wooden springs are attached directly to the axle-bed and bolster, when the carriage is constructed without reaches.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. The box J, elastic packing or spring K, and the extension braces or rods L L, attached to the side springs G G, substantially as and for the purpose specified.
2. The combination of the side springs G G with the C-spring I, by the shackle-conned tion H, the C-springs extending around the axle-bed and attached to the reaches, substantially as described.
3. The springs E E, crossing the upper ends of the springs G G, and passing over the bolster and attached to the forward ends of the outside reaches, substantially as described.
In witness whereof I have hereunto set my hand and seal.
JOSIAH R. LOCKE.
