Elma/whoa LEONARD A. YOUNG, OF DETROIT, MICHIGAN.
SPRING CONSTRUCTION.
Specification of Letters Patent.
Patented Apr. :1, 1911.
Application filed August 24, 1910. Serial N 0. 578,793.
To all whom it may concern:
Be itknown that I, LEONARD A. YOUNG, a citizen of. the United States of America, residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Spring Construction, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to spring construction for use in automobile or car seats and the like and especially to an arrangement of parts whereby the spring members are firmly secured in position without the aid of rivetsand without the-necessity of perforating or slotting the parts" to which they are attached.
The invention consists in the matters hereinafter set forth and more particularly pointed out in the-appended claim.
In the drawings, Figure 1 is a plan view of a spring cushion that embodies features of the invention. Fig. 2 is a view in detail partly broken away showing the method of securing a spring in place. Fig. 3 is a view showing a modification of a supporting strip. Fig. 4 is a plan view in detail of a portion of the supporting strip with inserted parts of the springs. Fig. 5 is a view in detail of a modification.
As herein indicated, abase is formed of metal strips 1 having upturned parallel flanges 2- separated by suflicient interval to receive tires which form spring coils 3. In preferred form the strips are inverted hollow tees-as indicated in Figs. 1 and 2 but may be of any desired cross-section that has parallel upturned marginal portions, as for example, the U-shape shown in Fig. 3. The spring coils 3, which are of conventional type, are each secured at their lower ends to the base members by bending the last turn of the coil downwardly at substantially right angles to the plane of the coil and inserting the down-turned portion between the flanges of a base strip. The latter are then pinched together and bent laterally as indicated at 4. If the bend is carried close to the lower part of the base strip it crimps or otl'sets the downturncd portion of the wire coil. By this method of construction each coil is firmly locked to the base strip at the exact place desired without the necessity of forming tongues in the base strip or punching slots or apertures therethrough. The coils cannot move along the strips neither can the ends of the coils work out as the depressed and oil'sct flanges clamp them firmly in position. The flanges may be crimped or offset in either direction or they may be bent alternately or they may be oil'set below the margins of the flanges if it is desired to keep the latter straight. This construction is indicated in Fig.
As there are no perforations or slots there is no necessity of putting up sets of bars for; special forms of springs as it is only'necessary to cutthe bars to proper length. insert the springs at the places desired and fasten them by crimping the flanges.
Obviously, changes in the details of construction may be made without departing from the spirit of the invention and I do not care to limit myself t'o'any particular form or arrangement of parts.
lVhat I claim as my invention is:-
In spring construction, a strip having pan allel. spaced flanges and a spring. a portion of whose end coil adjacent its flanges is bent into a plane substantially parallel to the major axis of the spring and is inserted between the flanges, the latter being drawn together and laterally displaced within the arc of the segmental inserted portion.
In testimony whereof I allix my signature in presence of two witnesses.
