FRANK P. DARCY, OF KALAMAZOO, MICHIGAN.
SPRING.
SPECIFICATION forming part of Letters Patent No. 773,312, dated October 25, 1904.
Application filed December 19, 1903. Serial No. 185,833. (No model.)
To all whom it may concern.-
Be it known that I, FRANK P. DARoY, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Springs, of which the following is a specification.
This invention relates to improvements in spring structures.
It relates particularly to cushion-springs for seats and the like, although it is applicable for use in other relations.
The objects of this invention are, first, to provide an improved spring structure in which helical or conical springs are used which can be readily transported in the knockdown or disassembled condition and readily and quickly set up or assembled by an inexperienced workman; second, to provide an improved spring structure which is economical to produce, in which the springs are securely and rigidly held in position, and one which is du-' rable in use.
Further objects and objects relating to structural details will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawings,.forming a part of this specification, in which Figure 1 is a detail cross-sectional view of a seat-cushion structure embodying the features of my invention. Fig. 2 is an enlarged detail plan view showing the relation of one of the springs C to the supporting-strip B. Fig. 3 is an enlarged detail perspective view showing one end of the supporting-strip B and one of the conical springs Gin position therein.
In the drawings similar letters of reference refer to similar parts throughout the several views.
Referring to the drawings, the frame A here illustrated is the frame of a carriage-seat cushion and is of the usual construction or form. It may, however, be of any construction or form desired. A supporting-strip B is provided for each row of springs C. The ends of the supporting-strip B are preferably bent upwardly to' rest upon the top of the seat-frame, where they are secured by suitable nails. These bent-up portions are preferably of such length that the body of the strip rests upon the seat-platform when in use. The supporting-strip B is formed of sheet metal. The body portion of the strip B is suitably conformed in cross-section and is slotted at b b, there being a pair of oppositely-arranged slots arranged through the body for each spring which it is desired to support by the strip. The bottom coil of the spring 0 is slipped through these slots. The slots 6 are of such length that the coil inserted therethrough must be somewhat collapsed, so that when it is inserted the tension thereof retains it in the slot. The springs are thus supported in a very rigid manner and are entirely'independent of each other except as connected through the supporting strips. Each spring is thus provided with a comparatively wide supporting-base.
The strips B are very readily formed of sheet metal, and I preferably form them into V shape, as illustrated. However, the same could be made U-shaped or in any angular form and a very satisfactory structure be produced. The strips B may be formed of comparatively light material and still possess sufficient rigidity and strength to properly support the springs.
The springs are very quickly secured to the strips, and any spring can be removed therefrom very readily without disturbing the other springs should it become necessary or desirable. Ifdesired, the portion of the spring inserted in the slots may be shaped to add to the gripping effect, as by making them angular or otherwise. I find, however, that this is unnecessary, as the springs are securely re: tained without this.
My improved spring structure is very economical to produce and is durable in use. The same may be shipped in the knockdown state and may be readily set up by inexperienced workmen, or, if desired, they may be secured to the strips, and thus shipped in a comparatively compact package.
I have illustrated and described my improved spring structure in the form preferred by me on account of its simplicity and the economy of producing the same.' I am, however, aware that it is capable of considerable structural variation without departing from my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a spring structure, the combination of a suitable frame; conical springs C; and sheet-metal strips B, \I-shaped in cross-section, having oppositely-arranged slots 5 therein into which the bottom coils of said springs are inserted under tension, for the purpose specified.
2. In a spring structure, the combination of a suitable frame; conical springs; sheetmetal strips, angular in cross-section, having oppositely-arranged slots therein, into which the bottom coils of said springs are inserted under tension, for the purpose specified.
3. In a spring structure, the combination of a suitable frame; helically-coiled springs; sheet-metal strips suitably conformed in cross section, having oppositely arranged slots therein into which the bottom coils of said springs are inserted under tension, for the purpose specified.
4;. In a spring structure, the combination of an upright helically-coiled spring; a strip of sheet metal suitably conformed, having a pair of slots therein into which a coil of said spring is inserted under tension, whereby said spring is supported and retained in position.
5. In a spring structure, the combination of an upright helically-coiled spring; a support therefor having a slot therein into which a coil of said spring is inserted under tension, whereby said spring is supported and retained in position.
In witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.
