VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 403,243, dated May 14, 1889.

Application filed March 5, 1889.

To all whom it may concern:

Be it known that I, CHARLES M. BLYDEN- BURGH, a citizen of theUnited States, residing at Riverhead, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a full and clear, description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a bottom view of a vehicle-body, showing a portion of the runninggear and torsion-springs. Fig. 2 is a spring of modified form. Fig. 3 is an enlarged view of one end of the bolster.

My invention relates to vehicle-springs and the means for securing them to the runninggear, whereby couplings, coupling-bolts, clips, &c., are dispensed with; and my invention consists, essentially, in torsion-springs having one end secured to the sill or bottom frame and the opposite end bent inwardly at right angles, and also in constructing the head-block or bolster, so that the free end portions of the springs may be inserted in the ends of said head-block or bolster, or be secured lengthwise along its top or bottom, as I shall hereinafter fully describe and claim.

The object of my invention is to so construct and shape the springs of a vehicle as to require no coupling-eye to be formed on the end which is usually attached to the running-gear, thereby dispensing with the use of couplings, bolts, clips, and like devices, and at the same time to so dispose of the springs that they will be efficient in action, the said springs being also cheaply and quickly made and applied.

To enable others skilled in the art to make and use my invention, I will now describe the same and indicate the manner in which I carry it out.

In the said drawings, A represents the sill or bottom frame of the vehicle. B is the reach, 0 is the axle, and D is the bolster or head-block, all of which may be of any wellknown construction, except the bolster or head-block, which in the present case has its ends bored lengthwise, and provided with bushings of any suitable material, to prevent too rapid wearing away of the wood and the consequent enlarging of the end openings.

The springs E consist each of a torsion-coil,

Serial No. 301,852. (No model.)

of regular or irregular form, as shown in Figs. 1 and 2, and have one end adapted to be secured, as at a, to the vehicle body or sill, and by clips I) or otherwise. The spring after being thus secured is coiled or bent in any desired manner to form the free or vibratlng arm 0, which extends parallel with the sides of the bottom or sill, and has its extremity or end bent inwardly at right angles with said arm, as at d, and inserted into the bored ends of the head-block or bolster D, as shown in Figs. 1 and 3, or may be secured on its top or bottom, whereby a pivot-connection is formed between the springs and bolster or head-block and the liability of the springs being displaced being reduced to a minimum.

Another important feature of the construction specified is that the right-angled portlon d and the arm portion 0 permit a free vertical action of the body and yet secure a bearing in front of the body and in a direct line with the center of the coil, thus preventing or over coming the twisting motion always present when the bearing is at the side of the center of the coil.

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

1. Torsion-springs for vehicles, having one end bent inwardly parallel with the bolster or head-block, in combination with a bolster having recesses for the bent ends of the springs, whereby a pivot-connecti on is formed, substantially as herein described.

2. The combination of a bolster or headblock having its ends bored lengthwise, and torsion-springs having their front ends bent inwardly and passed into the bored ends of the bolster, substantially as described.

3. The combination of a bolster or headblock having its ends bored lengthwise, and torsion-springs secured to the body of the vehicle and provided with vibrating or free arms, which are bent at right angles at their front portions and inserted into the bored ends of the bolster, whereby a pivoted connection is formed between the springs and bolster, substantially as described.

CHARLES M. BLYDENBURGH.
