CAR-SEAT SPRING.
Specification of Letters Patent.
Patented Feb. 17,1914.
Application filed January 22, 1912. Serial Nol 672,724.
To all whom it may concern:
Be it known that I, PAUL G. LEISTNER, a citizen of the United States, and resident of St. Charles, Missouri, have invented certain new and useful Improvements in Car-Seat Springs, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. p
My invention relates to improvements in car seat springs, and the object of my invention is to construct an all-metallic spring support for car seats and the like in which I employ as a top or support for the cushion crossed metallic strips to which are secured at intervals coil springs, the strips having between each pair of springs transverse downwardly projected V-shaped depressions which serve to absorb or take up lateral movement of the springs so that when weight is applied to a certain section of the springs the remaining springs will not be moved and the entire seat thus distorted.
With the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claim and illustrated by the accompanying drawings; in which.
Figure l is a plan of a seat spring. constructed according to my invention; and Fig. 2 is an enlarged, detail sectional elevation taken on the line 2-2 of Fig. 1.
Referring by numerals to the accompanying drawings: 1 designates the frame of my springs which is preferably formed from round wire. Extended lengthwise of the frame are the metallic strips 2, each end of each strip being secured to the frame 1 by eyes 3 which embrace the frame. Extended transversely of the frame are the strips 4 which connect with the frame '1 in the same manner as the strips 2. The margins 5 of each of thestrips 2 and 4 are down-turned as shown in Fig. 2 and the strips are preferably interwoven as shown in Fig. 1. At the points of intersection the strips 2 and 4 are each provided with perforations which register, the material surrounding the perforation in the uppermost strip being countersunk at 6 toprovide a seat for the head of a rivet 7 so that the rivet head will be flush with the upper surface of the uppermost strip.
8 designates a coil spring having at its upper end an eye 9 which embraces the shank of the rivet 7.
10 desi ates a washer which is slipped over the s ank of the rivet andbeneath the eye 9 of the spring. The lowermost end of the'shank of. the rivet is then upset to form a head 11, the rivet serving the double function of holding the strips against relative movements and holding the upper end of the spring in place. The bases of the springs are united in any common manner, hence I have not deemed it necessary to illustrate or describe such a connection. I
In the bodies of the strips 2 and 4 between the points of connection with the coil springs 8 there are theintegral yielding members 12 which are formed by crimping the strips transversely and whose office is to absorb the relative movements of the sections of the body portions of the strips connected with the supporting-coil springs 8.
It has been customary in the art to make the members which connect the top ends of the coil springs 8 sectional and introduce between the sections separate yielding members, usually in the form of coil springs.
By employing the metallic strips I obtain a surface which supports more evenly the cushion and by turning the margins of the strips downwardly I practically eliminate the wear of the cushions by abrasion.
I claim:
The herein described car seat spring, comprising a rectangular metallic frame, crossed interwoven metallic strips having their ends secured to said frame, each strip having throughout its length alternate plain and countersunk rivet holes, and down-turned crimps between said rivet holes to provide for longitudinal elasticity of the strips and each of said strips having its side margins down-turned, a coil spring arranged to be v secured to said strips at each of theircross ing points, and a rivet at each of the crossing points of said strips for securing said strips and also said springs,'the head of each rivet arranged to be wholly embedded in said countersunk holes.
In testimony whereof, I have signed my name to this specification, in presence of .two subscribing witnesses.
PAUL G. LEISTNER.
