VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 412,665, dated October 8, 1889.

Application filed June 15, 1889.

To all whom it may concern.-

Be it known that I, GEORGE E. RAYMOND, a citizen of the UnitedStates, residing at the city of Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a specification.

This invention relates to a spring-connection to the body of a vehicle, and to arms which are designed in whole or in part to support the vehicle-body, and particularly relates to improvements in the vehicle-spring de scribed in the patent issued to George E. Baymond & (30., June 4, 1889, as sole assignee of Silas H. Raymond; and the invention consists in the use of bent or curved spring in combi nation with other parts fully described hereinafter, the object being to simplify the construction referred to in said patent. This objectl accomplish by means of the mechanism illustrated inthe accompanying drawings, in which Figure l is a longitudinal sectional view of my newly-invented spring through the center of the line of attachment of such spring to the vehicle-body. Fig. 2 isa side elevation showing a preferred form of spring which I design to use. Fig. 3 is a modified form of the parts shown in Fig. 1. Fig. 4 is another modified form of the same parts, 'and Fig. 5 shows a bottom view of a portion of a vehiclebody with a single spring.

Similar letters refer to similar parts througlv out the several views.

0 represents a portion of the vehicle-body.

D represents the spring, curved between the point of attachment to the body and the center of the spring for the purpose of allowing said spring to be acted upon by the weight of the vehicle-body and in order to obviate the necessity of a movable shackle attachment for the spring. The spring D is bolted or riveted directly to the vehicle-body. or timbers attached to the body, as shown in the drawings by A A. It then curves a sufficient distance to allow the spring to play freely without any movement at the point of attachment to the body.

H H represent two arms supported at points B B to the side rail of the vehicle. These Serial No. 31 L390. (N0 model.)

arms are pivoted to the body or timbers connected to the body at the point E E.

In Fig. 1, K K represent sliding shackles,

each pivoted at the lower end to the inner end of the arms H H, and adapted to have a sliding movement upon the spring D, the obj ect being to allow'the inner ends of the arms to move to and from each other as the spring is pressed upon from above.

In Fig. 3, K represents a single shackle having two links L and L. Each of these links is pivoted to the stationary shackle K and to the end of the arms H. It will readily be seen that in this construct-ion the links L and L will allow for the free movement of the arms H H.

In the modified form shown .in Fig. 4 the shackle K is made preferably stationary with relation to the spring D, and is provided with a bolt P. The arms H H are slotted, as shown by S S, and are made to lap by each other, so that the bolt Ppasses through the shackle K and through the slots in the inner ends of the arms. This construction allows for the free movement of the inner ends of the arms H H. The form of attachment of the inner ends of the arms to the spring is not material, so long as those ends of the arms have a free movement, so as not to interfere with the free movement of the spring.

The general shape or form of the spring 1) may be varied; but in order to have itwork freely it mustbe curved sufficiently to' allow for the vertical movement of the shackles and the inner ends of the arms H H; otherwise it would be necessary to attach the spring to the body of the vehicle by means of movable bearings, which necessity it is my object to obviate.

The spring may be made of a single piece of metal or several pieces; or several pieces of spring metal may be placed side by side and attached together so as to form a spring. The form of the spring-bars is immaterial so long as the spring spans the space 'betweenthe points of attachment to the vehicle-body and are bent or curved to allow a free movement without movement at the point of attachment to the vehicle-body.

I do not claim, broadly, the combination of the vehicle-body and the arms supported at their outer ends by side bars, and a spring attachment at each end of the body, near the outside thereof, and spanning the space between such connecting points, for the purpose of supporting the body of the vehicle, as I understand such invention is broadly claimed in the patent hereinbefore referred to.

Having thus described my invention, whatI claim to have invented, and desire to secure by Letters Patent, is

In a vehicle, the combination of the vehiclebody, arms supported at their outer ends by side bars, a spring attached at each end to the body, near the outer side thereof, by a rigid attachment to the body and spanning the space between such points of attachment, said arms pivoted near the center of reach arm to the body, and at their inner ends connected to the spring near the center of such spring, said spring having a curved form on either side of its center, and adapted to allow for the vertical movement of the center of the I GEORGE E. RAYMOND. [L.S.]
