UNITED STATES PATENT. OFFIC BYRON J. HEALY, OF KALAMAZOO, MICHIGAN.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 403,666, dated May 21, 1889.

Applicatioufiled February 21, 1889. Serial No. 300,784:- (No model.)

To aZZ whom/it may concern.-

Be it known that I, BYRON J. IIEALY, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, 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 to use the same, reference being bad to the accompanying drawings and the letters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to that class of vehicle-springs whereby the ordinary side bar may be dispensed with, if desired, and has for its object cheapness, durability, and easy riding, also a way of producing different tensions of elasticity of the springs, as will be described hereinafter.

Referring to the drawings, in which like parts are designated by similar reference-let ters wherever they may occur throughout the difierent views, Figure 1 represents a vertical longitudinal section view of a vehicle-body provided with my improvements. Fig. 2 is an inverted plan view of the same, showing the exact shape of the spring-supports and theirconnection with the spring. Fig. 3 shows the spring with the hooked ends separate from the supports.

In referring to the lettered parts of drawings, A designates the vehiclebody, which may be of any desired pattern.

B is the springs, which are attached to the body at their center and supported at their hooked ends by the lever-arms C C C O.

In Fig. 2 may be seen the exact shape of the spring-supports and their attachment to the springs. Th at portion of the supports marked D is the middle portion, and is approximately at right angles to the arms, and is pivotally attached transversely to the bottom of the vehicle-body near its center, and performs the functions of a journal and equalizer to the arms and springs.

E is a brace connecting the journaled portions of the supports together and held to its place by the clips F and apart from the body by blocks .I, which in this case are shown as rubber, but may be made of any kind of material, or can be dispensed with entirely by placing thesupports against the bottom of the vehicle; but I find this way very convenient to adjust the staples or hangers F, and also to prevent rattling.

II designates the endsof the springs, which are hook-shaped and engage the support ing-arms 0 near their center. The ends of the arms are sprung outward slightly when attached to the gear, which prevents any rattling of the spring on the bar or arm of support. The hooks of the spring are made large enough to take the rock or pitch of the arm when not in use, but rest squarely on the arm when loaded. The pitch of the arm may be changed by raising or lowering thehangers by their threaded ends and nuts.

The letter I in Fig. :2 designates the clips and bolts fastening the springs to the body. These may be moved to different holes, or slots in the bottom of the body may be employed to slide the spring backward or forward to change its fulcrum and leverage on the arms 0 O.

In explanation it will be observed by referring to Figs. 1 and 2 of the drawings that the springsupports are journaled to the body by their middle portion, D, and the arms 0 attached at their ends G to the running-gear of a vehicle, and the springs attached to the bottom of the Vehicle and resting on the arms 0 near the middle, form an elastic fulcrum to the supporting-arms, and may be increased or diminished by moving the springs backward or forward on the supports, and that any pressure downward on the body exerts pressure on the springs by the arms 0 C C 0.

Eating thus described my invention, what I claim, and desire to secure by Letters Patent, lS-

1. A vehicle-spring consisting of a bowed or Ushaped spring and body-support, its middle portion journaled to a vehiclebody and its arms elastically fulcrumed by means of a cross-spring to a vehicle-body, all for the purpose specified.

2. A vehicle-spring support made in one continuous piece, bowed or U-shaped, having the arms 0 0 approximately at right angles to the middle portion, D, which is journaled to the vehicle-body, the free ends of the arms 0 0 attached at G to the gear, and the arms 0 C C G supporting the springs and body from the gear, all for'the purpose specified.

' 3. A vehicle-spring consisting of a bowed shaped spring and body-support having the middle portion journaled to a vehicle-body and the free ends or arms extending on each side of the body to the gear, and the semielliptic spring reaching across the arms and supporting the body, for the purpose specified. 4:. In combination, the bowed or U-shaped spring-supports having the middle portion pivotally attached to a vehicle-body and the ends attached 'to the gear, and the semi-elliptic spring having the hooked ends engaging the arms and supporting the body, as shown and described, and for the purpose specified.

tions, and the gear, all as described and shown, 3 5

and for the purposes specified.
