PETER MILLER, 0F GLOVERSVILLE, NEW' YORK, ASSIGNOR -OF PART OF HIS RIGHT TO CALVIN c. ALVORD AND WILLIAM 'H. SEYMOUR, OF

IMPROVEMENT'IN WAGON-SPRIN GS'.

Specificationforming part of Letters Patent No. 178,073, dated May 30, 1876 application filed January 12, 1876.

lb all whom it may concern 'sional strain upon the mainportion of the spring-bar is produced by turning the attaching and supporting ends at a right angle therefrom, by which improvements a torsion-spring is obtained, which is simple and cheap in construction, strong and efl'ective in operation, and overcomes to a great extent the rocking and swinging movement of the vehicle. It

consists in the construction, arrangement, and combination of parts hereinafter fully described. i

.The accompanying drawing fully illustrates my invention.

Figure 1 is an isometric View of the rear end of a vehicle, showing my improvedsprings Figs. 2 and 3 are detail views of my invention.

Similar letters of reference indicate corresponding parts. I L

A'represents the-bottomof a vehicle-body, to each end of which is attached a set of my improved springs, which consist of' the two spring-bars designated in the drawings as Nos. 1 and 2. The main or central portion a and (1 respectively, of these spring-bars is straight, and extends across the bottom of the body A. Near the edge of the body A the spring-bar No. 1 is turned outward at a right angle to the portion a and formed into adownwardcurved arm, N, which, being provided with an eye, 0, at the end, is attached to the stirrup s by the coupling r Near the opposite edge of the vehicle-body A the spring-bar N o. 1 is provided with a shank or enlargement, 0

standing at a right angle to the main portion a and in an opposite direction from the arm b at the other end thereof, which shank is rigidly bolted to the vehicle-body. The springbar No. 2 is formed and attached in a similar manner to. that 0f the spring 'bar Noel, but

has its arm I) and shank at opposite sides, respectively, to adapt it to the opposite side of the vehicle, and its shank c is bent over the main portion a of the spring-bar No. 1, so as to avoid cutting away material from the vehicle-body. The goose-neck or supportingarm of the stirrups s and 8 stand transversely across the axle to support the arms I) and 11 which are parallel with the track of the vehicle, and the usual coupling 1 is interposed between the stirrup and arm of the spring to add elasticity to the latter, and relieve the former from excessive strain.- 6 and e are staples supporting the spring-bars at the shank, and u and u are staples or clasps supthus prevents the vehicle from rocking sidewise; whereas, if the attaching shank or free end of the spring-bar is turned in the same direction, and parallel with the coupling or supporting ends, as heretofore constructed,

the downward strain 'on one side of the vehicle has a tendency to throw up the opposite side, and consequently increases the side rocking. Besides this, I am enabled to attach the main portion a a near the ends of the vehiclebody, and thereby, in a great measure, prevent longitudinal swinging or rocking. To still further overcome the side rocking, I place the stirrups 's s transversely on the axle or bolster, and parallel with the track. of the vehicle.

Neither do I claim torsion-springs with their main'portion placed longitudinally under the vehicle-body, as they either allow oneside of the vehicle to be depressed without affecting the opposite side, or cause a diagonally-swinging movement, and are generally more complicated and expensive, hence do not accomplish the object soughtin my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- l v 1. The improved vehicle-spring herein described, composed of the spring-bars Nos. 1

and 2, consisting,respectively, of the main from the outward-turned coupling or supporting arms 12 b, at the opposite end of the main central portion a a and at right angles thereto, placed with their straight main central portion a a transversely under the body A, at or near the end thereof, and rigidly. attached thereto at the shanks c '0 and the stirrups 8 .8 standing transversely on the axleo'r bolster, and parallel with the track of the vehicle, all constructed, arranged, and coinbined substantially as and for the purpose specified.

In testimony whereof I have signed my name and affixed my seal -in the presence of two attesting witnesses at Gloversville, in the county of Fulton and State of New York, this 6th day of January, 1876.

PETER MILLER.
