SPECIFICATION forming part of Letters Patent N0. 783,705, dated February 28, 1905.

Application filed August 10, 1904. $erial No. 220,235.

To rtZZ 1071/0772 13/ 77'2/11/5 concern:

Be it known that I, RILEY W. SHAW, a citizen of the United States, residing at Ypsilanti, in the county of ashtenaw and State of Michigan, have invented a new and useful Bed-Spring, of which the following is a speciiication.

My invention relates to spring-mattresses, and has for-its objects to produce a comparatively simple inexpensive device of this character in which the necessity for the employ- ,ment of transverse braces or tics is obviated;

one wherein the individual springs will yield both longitudinally and transversely, thus insuring a uniform distribution of the tension and a consequent prolongation of the life of the mattress; one in which the tension may be readily varied or adjusted, and one wherein the individual composite members or springs Will lie in a si'ibstantially uniform plane, thus presenting a normally even surface for the reception of the bedding.

With. these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

in the accompanying drawings, Figure 1 is a top plan view of the mattress embodying my invention. Fig. 2 is a detail perspective view of a portion of the spring fabric. Fig. 3 is a detail sectional elevation taken on the line 3 3 of Fig. 1.

Referring to the drawings, .1 designates the mattressframe, comprising end bars 2 and 3 and side rails 4, this frame being of the usual or any appropriate construction and material.

The spring-mattress 5, constituting the subject of my invention, is composed of a plurality of individual springs 6, each formed from a single length of spring-wire bent into shape, as herein shown, to produce at one end of the spring 621 spiral coil or whirl 7 and a pair of divergent arms 8, leading, respectively, from the terminals of the coil and between which the latter wholly lies, and a pair of longitudinally, reversely, and outwardly bowed spring arms or members 9, formed respectively continuous with the arms 8 and oining the latter by an acute angle to thus produce seats 10, disposed upon opposite sides of the coil '7, the teri'ninals of the Wire being bent to produce upon the arms 9 terminal engaging portions or hooks l1. Attention is directed to the fact that portions of the individual springs 6 normally lie in a common and substantiall y horizontal plane and that under longitudinal tension exerted at the points 10 the spring-arms 9 will yield or straighten, while at the same time the coil 7 will be contracted through the medium of the arms 8, whereby both a longitudinal and transverse spring action or tension is obtained.

Attached to thccnd bar 2 of the fral'ne by means of tension bolts or elements 12 is a tension bar or member 13, formed from angleiron and havingits horizontal liange provided with perforations or other suitable seats 14, adapted to receive the hooks 11 of the adjacent springs of the mattress, while to the bar 3 of the frame is attached a series of clips 15, carrying, respectively, substantially U-shaped engaging devices or staples 16, the arms of which are provided with terminal engaging portions or hooks 17, which engage the seats 10 of the adjacent springs. From this arrangement it is apparent that the mattress is firmly but detachably connected with the frame and that the tension may be readily varied or adjusted by manipulation of the bolts 12.

In assembling the individual springs 6 to compose the mattress 5 the said springs are arranged in transverse rows and in staggered relation longitudinally, a pair of the springs in the first row having their adjacent arms 9 engaged, respectively, through the medium of the hooks 12 with the seats 10 of a spring in the second row, while the latter spring has its arms 10 engaged, respectively,through the medium of the hooks .11 with the adjacent seats 10 of a pair of springs in the third row, whereby the arms 10 will conjointly form substantially continuous serpentine strands or courses throughout the mattress, and when the latter is placed under tension the tension will be trai'ismitted from one spring to another throughout the entire fabric and in directions both longitudinally and transversely of the mattress.

From the foregoing it is apparent that I produce a simple device admirably adapted for the attainment of the ends in View, it being understood that minor changes in the details herein set forth may be resorted to without departing from the spirit or the scope of the invention.

Having thus described the invention, what is claimed is 1. A spring-bottom made up of a plurality of spring elements, each element being formed of a single length of spring-wire bent into a spring-coil with the opposite portions of the wire diverged outwardly at the same side of the coil and then rebent to form substantially V-shaped seats andoutwardly-bowed sides terminating at their free ends in hooks, all of the parts of the spring element lying in subterminating at their free ends in hooks, all of the parts of the element lying in substantially the same plane.

In testimony that I claim the foregoing as my oWn I have hereto affixed my signature in the presence of two witnesses.
