Application filed August 2:), 1912. Serial No. 717,783.

To all whom, it may concern.

' Be it known that I, VINCENT HENCE, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed-Springs, of whichthe following is a specification. The present invention relates particularly to a spring su port for beds and the like, wherebya yiel ing connection is established between'the bed-springs and the side rails of the bed-frame.

It will be understood that the ordinary bed-spring consists of a comparatively rigid framework, between the ends of which are stretched springs or any suitable yielding fabric, the corners of the framework resting upon the side rails of the bed-frame. This being the case, the bed-spring will not be evenly supported at its four corners, unless the bed-frame is standing on an even floor, and the bed-spring is perfectly true. Furthermore, when no yielding connection is provided for the corners of the bed-frame, the only spring-action which can be obtained is that in the fabric of the bed-spring itself.

I am aware of the fact that constructions have previouslybeen devised for providing yielding supports between the corners of the bed-spring and the frame. However, as a general rule, such yielding supports have always been in the form of structures entirely separate and distinct from either the bed-spring or the bed-frame, so that when they are used, the bed-spring isfsustained considerably higher than is desired. I am aware of a construction. in which the yieldin connection constitutes a portion of the be -spring itself, but in such construction, it has been necessary to extend a bar or other like device clear across the bed-frame This is objectionable both on account of theadded cost of such bars, and on account of the necessity for using a difierent length of bar.

for each widtlrof bed. y

The present invention is intended to ])rovidc thedesirable features of a construction in which the yielding connection constitutes a portion of-the bed-spring proper without the necessity of using a bar or the like, extending clear across from one side of.

the bed-frame to the other. In other words it is intended to provide a yielding connection for the bed-spring, the construction of which shall be entirely self-contained, thus making it unnecessary to employ bars, rods,

or any other supplementary devices whatsoever.

Other objects and uses will appear from a detailed description of the invention which consists in the features of construction and combination of parts hereinafter, described and claimed.

In the drawings, Figure 1 shows a perspective view of the corners of the bedspring and bed-frame, showin particularly the device of my invention; ig. 2 shows'a back view of the device; and Fig. 3 shows a-section taken on the line 3-3 of Fig. 2, looking in the direction of the arrows.

In the several figures, the corner post of the bed is designated by the numeral 4. One of the side rails 5 is shown, but the back rail is not illustrated for the reason that it. would be loweindown on the post. I

The numeral 6 designates the end bar or angle of the'bed-spring and the numeral 7 designates one of the side tubes or rods thereof. The ends of a portion of the yielding 'fabric are shown at the points 8.

The yielding connection of the present invention is designated by the numeral 9. 1

It constitutes one of the corners or risers of the bed-spring and thus serves to establish the connection between the end rail ('3 and the side bar 7' thereof. For this purpose, it comprises a back plate. 10 which is reinforced by side webs l1 and 12. A socket in the bottom portion 13 receives the end of the side bar 7, while atop plate 14 may be connected to the cross rail 6 by means of screws, bolts, or the like. In this way, a perfectly firm and solid connection is established between the side and cross rails of the bed-spring.

It is customary to allow the side rail of the bed-spring to sit down just inside of the side rails of the bed-fran'ic. This being the case, in order to establish ayielding connection between the bed-spring and the bedframe, I have provided a connection, in

which the downward pressure is exerted at downward thrust is direct, and there is no tendency to twist the angle-piece. For the purpose of guiding the angle-piece in its.

up and down movements, I have attached it to a short bar 18 which extends through slots 19 of the side Webs, and occupies a fixed position with respect to the side rail of the bed-frameas the bed-spring rises and falls. Rollers or the like 20 may be connected to the crossbar for the purpose of improving. its ridingi qualities. A guide rod 21 secured to the angle-bearing 17 has its upper end entered into andworking within a tube 22 which in turn is connected to the extension 16. The spring surrounds the rod and tube, so that the latter serve to prevent any buckling of the spring and further improve the riding qualities of the device.

For the purpose of facilitating the assembling of the several parts, and particularly inasmuch as it is desired to assemble them with the spring under an initial compression,.I have provided a screw-connection 23 between the angle bearing and the cross-rod. In'this way, the spring which isnormally longer than the distance between theanglebearing and the extension or flange 16 can be compressed-the necessary amount to bring the angle-bearing up to the cross-bar 17, and then the parts can be screwed together.

" For the purpose of still further guiding the angle-bearing and preventing any possible twisting, which might lock the cross-bar 18, I have provided a downwardly extending ear 24 on the angle-bearing which ear rests against the side face of the web 12.

Also, for the purpose ofimproving the riding qualities of the device as a whole, I have split the spring into parts. The'lower part is comparatively stiff, while the upper part 25 is of lighter construction and yields first.- A disk 26 is interposed bet-ween, the two springs. or initial movements of the bed-spring will be taken up by the spring 25 while heavier loads will cause the heavy spring tocome into action.v

I wish particularly to emphasize the fact that by means of the herein described construction, or its equivalent, I have provided anarrangement such thatthe weight is supported at a point directly above the side rail of bed-frame, so that the spring of the yield ing connection at all times subjected to a direct, thrust, and so that no twisting force is exerted on the angle-bea-ringor on the bar 1S. These results ajre'accomplished without the necessity of extending a crossbar entirely from one side rail of the bedframe to the other. In other words, by means of the arrangement hereinshown and described, or its equivalent, an entirely selfcont'ained structure is provided, notwith-i' standing the t'act that it really constitutes a corner connection of thebed-sprmg I claim: 1, In adevice of the class descr bed, the
