BED-SPRING FRAME.

Specification of Letters Patent.

Patented April 1'?, 1906.

Application led September 80, 1905. Serial 110.2801814.

To @ZZ whom t may concern;

Be it known that I, ROBERT NAYSMITH, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bed- Spring Frames, of which the following is a specification, reference being had therein to tho accompanying drawings.

This invention relates to certain new and useful improvements in bed-spring frames; and the invention has for its object to provide a frame for bed-springs wherein novel means is employed for holding a woven-wire fabric; also, iiovel means for supporting the bed-spring frame upon the frame of a bed.

A further object of this invention is to provide a bed-spring frame consisting of comparatively few parts, which are simple in construction, strong and durable, and. comparatively inexpensive to manufacture.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, illustrated, and claimed.

The essential features of the present invention are improvements upon the construction illustrated and described in my accomp anyiig application, filed under even date, and the present embodiments of my invention are necessarily susceptible to structural change without departing from the spirit and scope of the invention..

Referring to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which* Figure 1 is a plan of my improved bedspring frame, illustrating the same in position upon the frame of a bed. Fig. 2 is a sectional view taken on the line Qc of Fig. 1 looking in the direction of the arrow A of said figure. Fig. 3 is a sectional view taken on the line y y of Fig. 1 looking in the direction of the arrow B. Fig. 4 is a similar view taken on the line w w looking in the direction of the arrow C. Fig. 5 is a front elevation of one of the castings used in connection with my improved bed-spring frame. Fig. 6 is a side elevation of the same. Fig. 7 is a rear elevation. Fig. 8 is a front elevation of a casting, illustrating a modified form of construction. Fig. 9 is a side elevation of the same, and Fig. 10 is a rear elevation.

In putting my invention into practice, I have constructed my improved bedspring frame of four castings 1 1 and 2 2, two sections of tubii' g 3 and 4, two angle-bars 5 and 6, and a woven-wire fabric 7.

In Figs. 2 to 7, inclusive, I have illustrated in detail the construction of the castings 1 and 2, these castings being identical in construction. Each casting consists of a body portion 8, having an oval opening 9 formed therein. The one end of the body portion 8, which I will hereinafter term the "rea-r end of the casting, is provided with side Wings or 'flanges 1() 10, having openings 11 11 formed therein. The top of the body portion 8 adjacent to the rear end of the casting is provided with an upwardly-extending protuberance or lug 12. The rear end of the casting near its lower edge carries a hookshaped member 14, which forms a groove 15 at the rear end of the casting. The object of this groove will be presently described. The castings 1 1 are connected together by the section of tubing 3, which is oval in cross-section. The castings 2 2 are connected together by the section of tubing 4, which is similar to the tubing 3. These sections of tubing are cut the length it is desired to make the bed-spring frame, and when the ends of the tubings 3 and 4 are placed in the castings 1 1 and 2 2 these castings will be prevented from rotating upon the tubing. The castings 1 1 and the tubing 3 and the castings 2 2 and the tubing 4 form the side rails of my improved bed-spring frame, and these side rails are adapted to be spaced apart by the anglebars 5 and 6. In connection with the anglebars 5 and 6 and the side rails of the frame I employ a conventional form of woven-wire fabric 7, and the ends of this fabric are secured to the angle-bars 5 and 6 by metallic strips 16 16 and rivets 17 17, said rivets passing through the metallic strips and binding the ends of said fabric upon the bars 5 and 6. The ends of the bars 5 and 6 are provided with openings 18 18, and these openings are.

adapted to receive the upwardly-extending protuberance or pin 12 of each casting. In

placing the woven-wire fabric and the bars 5' and 6 in engagement with the side rails of the frame the bar 5 is 'first placed in engagement with the castings 1 and 2, and then the bar 6 is placed in engagement with the castings upon the opposite ends of the side rails, it being necessary to so assemble the bed-spring frame in order that the woven-wire fabric 7 can be properly stretched. /Vhen the bars 5 and 6 are positioned upon their respective castings, the vertical portion 19 of each bar seats in the grooves 15 of the castings and contacts with the side wings or ilanges 10 of said castings. In placing the bars 5 and 6 upon the castings, they are moved downwardly into engagement with the castings, the protuberances or pins 12 of said castings passing through the openings 18, formed in the bars 5 and 6, and if it is desired to secure these bars in engagement with said castings bolts or rivets 2O may be employed for securing the pierced wings 10 10 of each casting to the vertical portion 19 of each bar. Should it be desired to further insure a positive engagement of the bars with the castings, the strips 16 are pierced, as at 21, directly above the openings 18 of the bars, and the protuberances or pins 12 of the castings, extending through the openings 18 and 21, can have the material of their ends upset to form heads similar to rivet-heads, which will prevent the bars from becoming disengaged from the castings. The vertical portions 19 of the bars 5 and 6 engaging the grooves 15 of the castings relieves the strain upon the pins 12 of said castings when considerable weight is supported by the woven-wire fabric 7.

In Fig. 1 of the drawings, I have illustrated the frame of a bed consisting of posts 22, joined together by

bars

23 and 24. When the bed-spring frame is mounted upon the frame ofa bed, the hook-shaped members 14 of the castings 1 1 and 2 2 are adapted to engage the bars 24 24 of the bed and rigidly support the spring-'frame thereon.

In Figs. 8 to 10, inclusive, I have illustrated a casting consisting of a body portion 8, having an oval opening 9 formed therein, and this body portion is provided withahookshaped member 14 and a pin 12, similar to the casting illustrated in Figs. 5 to 7, inclusive, but the side wings or flanges 10 10 are dispensed with. This casting may be employed in lieuof the castings 1 1 and 2 2 in case it is not necessary to further secure the bars 5 and 6 to the castings otherwise than the protuberances or pins 12.

I claim- 1. The combination with a bed, of a bedspring frame consisting of castings, tubing connecting some of said castings together, angle-bars mounted upon said castings, pins carried by said castings and adapted to eX- tend upwardly into said bars, hook-shaped members carried by said castings and adapted to support said frame upon said bed, substantially as described.

2. The combination with a bed, of a bed* spring frame consisting of castings, oval tubing connecting some of said castings together, bars supported by said castings and adapted to support a wire fabric, hook-shaped members carried by said castings and adapted to support said frame upon said bed, means to detachably connect said bars to said castings, substantially as described.

3. In a bed-spring frame, the combination of castings adapted to form the corners of the frame, hook-shaped members carried by said castings and adapted to support said frame upon a bed, means to detachably connect a woven-wire fabric to said frame, substantially as described.

In testimony whereof I afliX my signature in the presence of two witnesses.
