SUPPORT FOR UPHOLSTERY-SPRINGS.

SPECIFICATION forming part of Letters Patent No. 767,375, dated August 16, 1904,

Application filed June 14, 1902- Serial No. 111,797- (No model.)

To (117/ whom, it may concern.-

Be it known that 1, GEORGE E. BIGELOW, a citizen of theUnited States, residing at VVorcester, in the county of Vorcester and State of 5 Massachusetts, have invented a new and useful Support for Upholstery-Springs, of which the following is a specification.

This invention relates to an improved means for supporting upholstery-springs-such, for

1 example, as are used under seats, couches,

beds, or for similar purposes.

The especial object of the invention is to provide a strong simple construction which can be put together without the use of special tools. I

To accomplish this purpose, the invention consists of a novel form of the supportingpiece for the springs and of the combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

Referring to the drawings forming part of this application for patent, Figure 1 is a partial plan View of a frame having a number of 5 springs arranged therein according to my invention. Fig. 2 is a perspective view of one of the springs. Fig. 3 is an end view, on an enlarged scale, of one of the spring-supporting pieces. Fig-4 is a bottom plan view of the 3 same. Fig. 5 is a partial perspective view illustrating the construction of the supporting-wires. Fig. -6 is a perspective view of the supporting-piece, and Fig. 7 is a perspective view of the supporting-piece when made of sheet metal.

The invention has special reference to a spring-supporting piece by which the ordinary conical upholstery-springs are locked in position on the supporting-wires and whereby the 4 supporting-wires are also looked together.

Referring to the drawings and in detail, A designates a supporting-frame, which may be the ordinary wooden frame of a seat, couch, or any other similar structure. Secured to the same are the supporting-wires 10, which are bent up in the ordinary way and which have sharpened ends 11, which are driven into the said frame. By this construction the lower part of said wires will be supported a considerable distance below the top of the frame A. Similar transverse wires 12, which have similar supporting ends 13, are also secured to the frame A. The supporting-wires 12 are arranged below the supporting-wires 10 at the points where the springs are to be applied, and, if desired, the wires may be oppositely arranged at the intersecting points where the springs are not applied, so that said supporting-wires will be woven together.

The wires 10 at the points where the same bear on top of the wires 12 have nicks or grooves 110 therein and the wires 12 have corresponding engaging nicks or grooves 120, so that said wires will interlock with each other at these points, whereby they cannot slip on each other.

B designates the spring-supporting pieces or clips. The same are preferably made out of brass, malleable iron, sheet metal, or a drop-forging, so that certain parts thereof can be bent as hereinafter described. Each of said spring-supporting pieces B has a slot or groove 16 on its under side, into which the' wire 10 fits, and also arms or fingers 17, in under which the wire 12 fits. Each springsupporting piece also has arms 18, so that the lower convolution of the conical spring C can snap into the same. Each spring has its upper free end united to its body portion by the twist 1 1 and the lower or small convolution bent inward or formed with reentrant sides, as at 15, as shown in Fig. 2.

The device is put together as follows: Each spring-clip is laid on a wire 10 and the wire 12 is fitted in under the arms or fingers 17. These arms or fingers are normally distended, as shown inidotted lines in Fig. 3. When both wires are in place in the clip, the fingers 17 are hammered to tightly engage the wire 12. This will lock the spring-clip rigidly on the wires 10 and 12, and the wires 10 and 12, by means of the notches 110 and 120, will be also rigidly secured together. The lower end of the spring C is then screwed or snapped into the piece B, the bends engaging the arms '18, whereby the spring will be permanently and strongly attached to the clip B.

The clips may be attached to the wires before or after the wires are attached to the frame A, as desired. In this way a strong and simple construction is provided which can be easily put together.

The details of construction herein shown and described may be Varied by a skilled 1nechanic without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a construction of the class described, the combination of an upholstory-spring, the bottom coil of which has rcentrant sides, and an attaching piece having upwardly-extending, inwardly-turning arms forming a socket into which the bottom coil may be forced by compressing the sides thereof, and in which the coil will be locked by subsequent expansion.

2. As an article of manufacture for use in constructions of the class described, a swingsimporting piece having fingers which extend into which the lower coil may be forced, and in which the coil will be locked by subsequent ex 'iansion, and, also having downwardly-extending lingers for engaging and locking'together a pair of cross-wires.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE E. BIGELOW'.
