- BEDSTEAD.

To all whom it may concern i Be it known that we, ANG LO Pnorn'ro, a subject of the King of Italy, and HARRY E. Gnoss, a citizen of the United States, residing at Pittsburgh, in the. county. of Allegheny and State of Pennsylvania, have in.- vented certain new and. useful Improvements in Bedsteads, of which the following is a specification.

- ()ur invention relates to the class ofsupports for bedsteads and it has forv its object to provide, in connection with the supportingframe of the bed springs, means whereby the supporting frame may be mounted upon a metal bedstead framework having main side and end bars, or upon the slats of an ordinary wooden or other bedstead.

The particular improvement consistsin a novel construction of support, hanger or clevis, pivotally connected with the cross bar members of the supporting frame, in

such a manner as to be thrown out underneath the endmost member of the frame and to engage-the side bars of the mainbedstead frame, or to be thrown backwardly alongside with the member to which it is pivoted with suflicient resilient binding engagement to fixedly hold it in retracted position and away from interference with the slats or other portions of the bedstead frame.

The invention is illustrated in the accompanying drawings in which Figure 1 is a partial plan view showing the bed spring and mattress supporting frame mounted upon the side bars of the bedstead. Fig. 2 is an enlarged cross sec tional View, indicated by the line II. II. of Fig. 1, showing both side bars of the bed stead, with the bed spring and mattresssupporting frame mounted thereon. Fig. 3 is a similar view showing the frame mounted on the ordinary slats of a wooden bedstead, the supporting hangers being thrown back in holding engagement with the cross bars. Figs. 4 and 5 are enlarged detail plan views showing the supporting hanger in extended and retracted positions, respectively.

In the drawings, 2 represents the side bars of the usual well-known metal bedstead, which may be of any suitable construction, but are preferably of angle shape. These bars extend longitudinally along each side of the frame and are preferably removably connected with the corner posts, as will be Application filed April 8, 1912. serial No. 759,677.

Specification of Letters rate'ntQ P t t A110. 25, 1914 which may be made in one, two or more sections, is composed of side bars 3 and transverse bars 4 connected together inany suitable manner, as indicated at 5, preferably by bending the ends of bars 4 into side contact engagement with the inner faces of bars 3 and riveting them together. This construction of joint is, incidentally, of advantage in providing a double thickness of the side and crossbars at the points where the sup porting hangers are located, thus providing a double thickness bearing for the hangers.

The spring frame 6 having the customary springs 7 is usually mounted upon the cross bars 4 providing a support for the mattress, or any other desired spring construction or mattress support may be utilized, without necessarily changing the. construction or functions of the invention. Y

Forthe purpose of providing a supporting engagement between the frame composed of bars 3 and 4, and the side bars 2, it. providethe hangers 8, preferably. one for each end portion of the cross bars 4. These hangers are made of fiat strip metal of sulficient size and thickness to provide ample strength and rigidity, and are bent into U- shaped form at their outer portions, adapted to fit over and embrace the upper portion of bars 2.

The hanger is so shaped as to provide a right angle joint, as indicated at 9, fitting around underneath the lower edge of side bars 3, and, incidentally, underneath the flanged ends of cross bars 4, as shown in Fig. 2, and is then extended backwardly underneath the side bar 3 and pivotally connected to the lower portion of bar 4 by a rivet or bolt, as indicated at 10.

The metal bar forming the hanger is twisted, as at 11, for one-quarter of a complete revolution, thus providing for side lapping of its inner end portion against the inner side face of'bar 4, a washer 12 being preferably employed between the pivoting end of the hanger and the cross bar, whereby to space the body portion of the hanger outwardly somewhat from the face of bar 4. Additional washers 13 may also be used, if desired. As thus constructed, the flat portions of the strip forming the hanger are thus, presented to the various engaging surfaces and the inner end of the hanger is thus well adapted to pivotal mounting alongside of bar 4. When extended, as shown in Fig. 2, the device thus presents the side bars 2 of the bedstead.

When it is desired to use the spring mattress frame on an ordinary bedstead provided with the usual Wooden slats 14, supported on the side bars 15, the hanger members are turned backwardly underneath side bars 3 and swung around and pressed upwardly, the curved edge 16 of the hanger strip binding with considerable pressure against the inner face of bar 4t, deflecting the hanger outwardly therefrom, as shown in Fig. 5, effecting spring pressure inwardly against bar 4 and resulting binding and holding friction. The metal strip of the hanger having. considerable resiliency this action is facilitated effectin a considerable degree of binding friction when the hanger is thrown clear up, as in Fig. 3, thereby positively holding it in reversed position and away from contact with any other portion of the structure, avoiding rattling, etc.

This spring action is directly facilitated by the use of the outer washer 13, whereby the out distortion, the washer also assisting in holding, by spring action, of the hanger against the frame.

' The advantages of the invention will be readily appreciated by all those familiar Copies of this patent may be obtained for nesses. hinge or pivotal omt 1s maintalned w1thwith this class of devices; it is comparatively simple and cheap inconstruction, efficient in operation, provides ample strength for the objects in view, and is not liable to get out of order.

Having described our invention, what we claim is: p

In a'mattress supporting frame, the combination with the end bar and a cross bar connected therewith at right angles, of a hanger having an outer U-shaped portion adapted to engage over a supporting side bar, a middle fiat portion adapted to bear simultaneously underneath the end bar and cross bar adjacent to their juncture and providing a support-therefor, and an inner portion twisted into alinement with the cross bar and pivoted thereto closely-adjacent to its face, the edge ofzthe twisted portion being adapted to spring laterally and bind against the face of the cross bar to effect frictional holding engagement therewith when the hanger is thrown backwardly thereon, substantially as set forth.

In testimony whereof we hereunto aiiiX our signatures in the presence of two Wit- ANGELO PROFETO;
