BED-SPRING FASTENER- Specification of Letters Patent.

Patented April 17, 1906.

To all whom it may concern:

Be it known that I, ROBERT NAYsMrrH, 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 Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in bed-spring fasteners; and the invention relates more particularly to a novel construction used in connection with the manufacture of bed-springs.

The present invention aims to provide positive and reliable means for effecting a perfect holding of a spring woven-wire fabric in a frame, and in this connection I have devised a novel construction which permits of the parts of the frame and its spring woven fabric being easily and quickly assembled and held to maintain a rigid, strong, and durable construction. To this end I have provided a metallic frame for spring woven-wire fabric which will permit of the same being manufactured at a comparatively small cost, and in connection with this construction I have devised novel means for supporting the spring-frame upon a bed.

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 and claimed.

The essential features of the present invention are necessarily susceptible to structural changes without departing from the spirit and scope of the invention; but the preferred embodiments are illustrated in the accompa nying drawings, in which- Figure 1 is a top plan view of a spring constructed in accordance with my invention, illustrating the same supported by a bed. Fig. 2 is a sectional view, taken on the line w as of Fig. 1, looking in the direction of the arrow A of said figure. Fig. 3 is a similar view, taken on the line y y of Fig. 1, looking in the direction of the arrow B. Fig. 4 is a sectional view, taken on the line w w of Fig. 1, looking in the direction of the arrow C. Fig. 5 is a perspective view of a malleable casting forming a part of my improved construction.

Fig. 6 is a perspective view of the same looking at the rear side of the casting, and Fig. 7 is a top plan view of the casting.

To put my invention into practice, I employ a construction consisting of four castings 1, two pieces of tubing 2, two angle-bars 3 3, a webbing of wire 4, or, as it is commonly known, woven-wire fabric, and numerous rivets or bolts and nuts to secure the parts together.

The castings 1 are identical in construction, and by referring to Figs. 5 to 7, inclusive, it will be observed that the malleable casting consists of a substantially keystone-shaped plate 5, the lower end of which is provided with a tubular extension 6, which is further joined to the plate 5 by a vertically-disposed rib 7, this rib extending from the top of the tubular extension 6 to the top edge of the plate 5. The tubular extension 6 is formed at right angles to the plate 5, and the inner configuration or area of the tubular extension 6 conforms to an oval, as clearly illustrated in Fig. 3 of the drawings. The rear side of the plate 5 is cut away, as at 8, and provided with a transversely-disposed slot 9, the formation of this slot providing a flange 10, the object of which will be presently described. The one side of the plate 5 is provided with a right-angular extension or lug 11. The top of the rib 7 is provided with an upwardly-extending protuberance or pin 12, the object of which will be presently described. Two of each of the castings are joined together by the longitudinally-disposed sections of tubing 2, (illustrated in Fig. 1 of the drawings,) and in cross-section this tubing is preferably formed oval to correspond to the oval opening of the tubular extension 6 of the castings, this construction being employed to prevent the castings from rotating upon the ends of the tubing 2. In practice these sections of tubing form the longitudinally-disposed sides of a frame which supports the web-lace 4.

The angle-bars 3 3 are adapted to be retained upon the castings 1 by the flange 10 and the protuberances or pins 12 of the castings. The ends of the angle-bars 3 are provided with openings 14 14, which are adapted to receive the pins 12 12 of the castings, as clearly illustrated in Fig. 4 of the drawings. The vertical portion of each of the bars 3 when the bars are placed on the castings is bars 3 3.

adapted to seat in the slots 9 of said castings and coincide with the plate 5 of each casting. Strips of metal 15 15 are employed for securing the fabric 4 to the bars 3 3, and the edges of the fabric 4 are clamped between the strips 15 15 and the horizontal portion of the anglebars 3 by a plurality of rivets 16 or the like fastening means, which are placed at intervals along the bars 3 3 to firmly retain the ends of the fabric 4 in engagement with the The fabric 4 may be made of any desired weave, and I employ a conventional form of woven Wire in connection with my improved construction.

In assembling the different parts of my improved construction the castings are first placed upon the ends of the tubings 2, these tubings having been out the proper length to obtain the desired length of bed-spring. The bars 3 3, which have been placed upon the ends of the fabric 4, are now positioned upon the castings, one of said bars being placed in position within the slots 9 9 of the castings and upon the pins 12 12, at which time the opposite end of the fabric is stretched until the bar 3 can be placed in the slots 9 9 of the castings 1 1. In this operation the bar 3 is further retained in engagement with the castings 1 1 by the protuberances or pins 12, which insure a further locking of the bar 3 within the slots 9 of its respective castings. To further insure a positive engagement of the bar 3 with its castings, the ends of the malleable protuberances or pins projecting above the bar can be flattened to form a rivet, which will permanently hold the fabric 4 in a taut condition between the bars 3 3. By this construction it will be observed that a substantially rectangular bed-spring and frame is formed, and inFig. 1 of the drawings I have illustrated the same in connection with a bed 17. It will be observed that when the spring is positioned upon the bed the right-angular lugs or projections 11 engage the side rails 18 18 of the bed near the foot and head pieces thereof, thus firmly supporting the spring-frame upon the bed.

I desire to call particular attention to the simplicity of the malleable-iron castings and to the manner of fastening the fabric to its frame. "By this construction I am enabled to manufacture the castings and their appurtenant parts at a comparatively small cost, and the simple manner in which the different parts of the bed-spring are assembled permits of parts of the bed-spring being shipped or transported in a knocked-down condition, it only being necessary to assemble the different parts when the bed-spring is to be used.

I am aware that heretofore it has been the customary practice to use pieces of tubing similar to the tubing 2. It has been the practice to use circular tubing, which was secured in different kinds of castings by keys but by the construction of the tubing 2 in cross-section and the construction of the tubular extensions 6 of the castings it -will be observed that the keys heretofore used are dispensed with and that the tubing will be prevented from rotating independently of the castings 1.

It will be apparent from the above description that I have devised a novel form of bed-spring frame adapted to support a fabric. In connection with the castings used I do not care to confine myself to the manner of supporting the same upon a bedframe, as in some instances the castings may be formed integral with the frame of the bed, which would practically serve the same purpose. The tubular extensions of the castings having oval openings formed therein may be dispensed with and the lower end of each plate provided. with an oval opening, this construction being of a more simple form than that illustrated.
