IMPROVEMENT IN SPRINGS FOR VEHICLES.

Specification forming part of Letters Patent No. ll, dated February 17,1874; application led November 21, 1873.

To all whom it may concern:

Be it known that I, JOHN CURTIS, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Spring-Vehicles, of which the following is a specification:

My invention relates to a compact, strong, and economical mode of supporting the body of a spring-vehicle upon runnii'lg-gear, which at the same time permits the use of alowbody with practically unlimited action.

Figure 1 is a perspective view o f an arrangement of springs with accessory parts embodying my invention. Figs. 2 and 3 are, respectively, a longitudinal and a transverse section of the same, with the body attached and in are respectively, a plan and a longitudinal section, showing a modification ofmy improvement. Fig. 6 shows by perspective view, and to a larger scale, some details of Fig. 4. Fig. 7 represents another modification of my improvement. Fig. 8 represents a modification of the device shown in Figs. 4, 5, and 6, the two perches being, as in said iigures, separated somewhat more than the width of the body, but being, with the head-block, composed of a single bent stick or rod of wood or steel.

The connection of the rear axlevtree A with the head-block B may be by customary perch C, or such connection may be by double perch C', substantially such as described in my patents of March 26, 1867, and August l0, 1870, and king-bolt D may. pass down through the head-block in the usual manner, as shown by strong lines in Figs. l, 2, 4, and 5 5 or, where fore wheels of large diameter coupled with ability of short turning is desired, the kingbolt may occupy a rearwardly-extendin g bracket, as shown by dotted lines in Fig. 4. Fastened by bolts E (or clips) at their mid lengths to rear axle-tree A and head-block B, respectively, are two common inverted bow-springs, F F', whose extremities support, and are connected by, side bars G G', which may be either of wood or of metal, as desired. From hangers or brackets H, extending inwardly from these bars, depend links I, which support and afford attachment for side springs J J', which, being bowed or upwardly cambered, as shown, are attached by bolts K (or clips) to the under side of the bed or body, and constitute the sole support of the same.

For additional security the brackets Hmay be also connected to the springs FF', by braces L, as in Figs. 4, 5, and 6, or the side springs may be supported by, and connected. directly to the end springs, as in Fig. 1. rlhe lowdown support of my side springs enables them, as well as the end springs, to be cambered boldly so as to afford an exceedingly strong, and, withal, sensitive bearing to the body, without placing the latter at an inconvenient or unsafe elevation 5 and in fact my said arrangement, especially that modiication of it shown in Figs. 4, 5, and 6, (in which the customary single perch is replaced by two perches separated from one another a distance somewhat greater than the width of the body,) permits the use of a body of almost any degree of depression, with any desired resilience of support.

By increasing the length of the hanger, or its equivalent, the body can be hung down aslow as may be required, and that without at all interfering with the use of high wheels. rI`he bars G G' being subjected to torsional action, and, constituting in fact a component part of the entire spring', are preferably made of steel or tough wood.

I claim as my invention- 1. rFhe springs F F' J J', links I, and bars G G', having hangers H, all combined to operate substantially as set forth.

2. The combination of the double orpaired perches C' C', springs J J', hangers H, links I, supporting members G G', and springs F F', constructed to operate substantially as set forth.

In testimony of which invention I hereunto set my hand.

Attest: JOHN CURTIS.
