VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 434,239, dated August 12,-1890.

Application filed May 20, 1890. $en'al No. 352,495. (No model.)

To all whom it may concern.-

Be it known that I, IRA L. BLAKESLEE, a citizen of the United States, residing at Kirkwood, in the county of Broome and State of New York, have invented certain new and useful Improvements in Vehicle-Springs and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to coil-springs for vehicles, more especially adapted for buggies and light wagons, and the object sought to be accomplished is to produce a light and easy spring which will more successfully combine simplicity, strength, and durability than those arrangements heretofore in vogue.

With this end in View my invention consists in certain peculiarities of construction and combinations of parts more fully set forth hereinafter, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a front elevation of my device as applied to a side-bar buggy,and Fig. 2 a bottom view.

My spring is formed of two parts A and B, each consisting of a single piece of resilient metal in rod, strip, or other convenient form, and constructed and arranged as follows: The ends a of the spring A lie parallel with each other along the bottom of. the vehicle-body .and their extremities b are bent in toward each other at right angles to the parallel portions, and staples or clips 0 secure both portions to the bottom 0. Thus the spring ends are rigidly held in position against said bottom and cannot work loose in any direction. These ends or extend to the sides of the vehiole-body and are coiled inwardly toward each other, forming the spirals c, from which extend, at an angle of about thirty degrees from the body-bottom, the arms cl. These arms are straight and parallel about half their length, and then converge slightly and curve upwardly, extending out a short distance beyond the side of the vehicle-body,where their ends (1 are bent at right angles toward each other, forming one continuouspiece, and thus constitutinga loop or bail e. The spring Bis arranged opposite the spring A and formed in a similar manner as the ends f, secured rigidly to the body portion, the coils g and spring-arms 71. forming the loop 1'. The ends f, however, do not lie parallel against the bottom of the vehicle-body like the ends a of spring A, but converge as they approach the sides of said body, thus bringing the coils g close together, and hence also the arms h, which slightly diverge as they extend away from said coils .to form the loop 6 and extend through between the arms (I of the spring A. The two loops or bails e and 1' cross each other directly beneath the center of the vehiclebody, and they are connected and held from sidewise movement by a spreader or crosspiece j, the several arms of the loops having sliding bearings through suitable openings K in said spreader. The ends at 2" of the loops are coupled by suitable shackles to the side bars when the springs are applied to a buggy, and when used with a light wagon to the axles in the front and rear of the latter, respectively. Thus a light and easy spring is constructed which is also strong and. durable, and the weight is equally supported by the two parts of the springs, and they are so connected and secured that no side motion and consequent wrenching and twisting of the parts can take place. 'It will also be seen that the springs are allowed an extended range of action, as the limit of their movement is not reached until the ends of the loops come in contact with the bottom of the body, this being'permitted to take place by the peculiar formation of the springs, as when an extra heavy weight is carried the loop 2' of spring B passes up between the coils c of spring A, while the loop (1 will also pass-the coils g, inclosing the same, they being arranged close together, as previously described.

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

1. In a vehicle, springs rigidly secured to the body-bottom and provided with coils, loops extending from said coils and intersecting each other, and suitable connections between the ends of said loops and the runninggear, substantially as described.

.2. In a vehicle, springs having ends rigidly secured to the body-bottom, suitable coils, in- V a loop, of an opposite spring consisting of ends rigidly secured to the vehicle-body, coils I 5 formed fronrsaid ends and close together, and a loop extending from said coils through the loop of the first spring intersecting it, substantially as described.

In testimony whereof I affix my signature in 20 presence of two Witnesses.

IRA L. BLAKESLEE.
