BRACE 4FOR BEDSTEADS.

SPECIFICATION forming part of Letters Patent No. 578,804, dated March 16, 1897. Application iiled .Tune 3, 1896. Serial No. 594,060. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH F. ANDERSON, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Braces for Bedsteads and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of bedstead-braces which embody chains or cords connected to devices attached to the bedsteadfralne,the chains or cords being also connected to centrally-arranged or intermediate adjusting devices.

The object of my invention is to provide a simple and improved device of this class which will possess advantages in point of strength, effectiveness, convenience, adaptability, adj ustability, inexpensiveness, and general efficiency, and which can be -readily applied to or removed from various sizes or types of bedsteads.

In the drawings, Figure l is a perspective view showing my improved bedstead-brace in position. tional view taken through one of the end clamps. Fig. 3 is a detail transverse sectional view taken on the line 1 l, Fig. 2. Fig. 4. is a detail transverse sectional view taken on the line 2'2, Fig. 2. Fig. 5 is a detail perspective view of one of the end clamps. Fig. 6 is a detail perspective view of the adjust? ing-lever in its initial position. Fig. 7 is a detail perspective view illustrating a modified form of end clamp. Fig. 8 is a detail longitudinal sectional view of the construction shown in Fig. 7. Fig. 9 is a detail transverse sectional view taken on the line 3 3, Fig. 8.

Fig. 10 is a detail transverse sectional View taken on the line 4 4, Fig. 8. Fig. l1 is a detail perspective view of the adjusting-lever in reverse position. Fig. 12 is a plan view showing the slotted portion of the adjustinglever.

Referring to the drawings, A A designate the end clamps, which comprise a body or base plate a, having at the outer end an upwardly-projecting flange a. The clamping devices are arranged in position so that the base-plate 0L is located horizontally under the Fig. 2 is a detail longitudinal sec` side piece B of the bedstead-frame, and the end flange a bears against the outer face of said side piece, as shown. The inner face of the iiange a is preferably provided With an inwardly-projecting offset or enlargement a2 at the top, which forms the bearing-surface and prevents marring of the molding-strip b, which is usually arranged at the bottom of the side pieces B of the 'bedstead. I prefer to also employ a covering c, Fig. 7, of suitable corresponding construction, formed of chamois-skin or other suitable material and adapted to fit over the flange a to prevent marring of the bedstead-frame.

Rubber washers or cushions may be employed between the bearingsurfaces of the clamping device and the bedstead-frame, if

desired.

D designates a slide carried upon the plate a and preferably constructed with a longitudinal slot or opening d, corresponding to the plaie a and receiving the same, so that the slide embraces the plate. At the outer end of the slide is provided an upwardly-projecting flange cl, adapted to bear against the inner face of the side piece B of the bedsteadframe, the side piece B being thus clamped between the flange a of the base-plate a and the flange d of the slide D. In the bottom of the slide D is provided a slot d2, intersecting the slot d, and depending from the bottom at the sides of the slot d2 are ears e e, between which is pivoted a cam-piece E upon a transverse pin e', so that the cam Works through the slot d2 and bears against the bottom of the plate 0L to lock or bind the slide D rmly in adjusted position. A series of two or more eyes or openings e2 may be provided in the ears c c for the transverse pin c to permit adjustment of the pin and corresponding adjustment of the cam.

F F designate two chains which have their outer ends respectively connected to the inner ends of the plates a c of the clamping devices at each side of the bedstead. This connection is preferably formed by a transverse recess f, formed in the inner end of the plate a, which recess is engaged by thel link of the. chain.

The inner ends of the chains are respectively connected to pivotally-mounted plates G and G2, carried upon a lever G, this connec- IOO.

tion being preferably formed by transverse recesses g and g2, respectively, formed in the ends of said plates and adapted to be engaged by the link of the chain. rIhe fulcrum end of the lever is preferably bent at an angle', as shown at g3, to provide for the passage of the pivotal plates with relation to eachother. The end plate G is pivotally mounted upon the end of the lever beyond the angle or bend g3, while the plate G2 is pivotally mounted upon the lever in rear of said angle or bend,

and the plate G2 is also preferably provided with an angle or bend gso that its outer end is brought within the same plane as the end lever G. The plates are mounted at opposite sides of the lever-bar G and are in divergent position, as shown in the first position in Fig. 6, when the chains are slack. To tighten up the chains and brace the bedsteadframe, the lever is carried around to the reverse position, (shown in the second position in Fig. 6,) in which operation the pivots of the plates form fulcrums for the lever and the plates are drawn toward each other, thus tightening the chains. When the lever is thus carried to reverse locking position, the fulcrum end of the lever rests between the two plates, as shown, and to provide for locking the lever in this reverse position with the chains taut angular brackets or catches g.5 g5 are arranged to project at opposite sides of the lever-bar in rearof the fulcrum end, which brackets are engaged with the chain connected to the end plate G', as shown in the second position in Fig. 6.

To enable a further adjustment of the plate G2 to further take up the chain when desired, the pivot pin or rivet h of the plate may be arranged in a curved slot h in the lever-bar G, this slot being formed on a longitudinal plane and having end recesses h2 h2 at an angle to its main portion, in which end recesses the pivot-pin h is adapted to rest at the termini of the respective initial and reversed positions.

In Figs. 7, 8, 9, and l0 I have shown modiiioations in the detail construction of the end clamp. The bearing-face of the flange d' of the slide D may be provided with a springplate I, working in a recess i in the face of the flange. I have also shown the slide with an interior recess 7c at the slot cl2, adapted to accommodate a corresponding block or plate K, having a serrated inner face 7c', which bears against the bottom of the plate a, the block or plate K being forced into engagement with the plate a by the earn-piece. Suitable bowed spring-plates Z may be interposed between the cam and the block K in the slot d2, and the top of the slide D is slotted or of open construction, as shown at fm, to enable handling of the block K when the slide is removed from the plate a.-

The operation and advantages of my invention will be readily understood.

The device is simple and effective, easy of operation and adjustment, and may be conveniently and readily detached from or attached to all types of bedsteads. The end clamps, lever, and chains are also readily detachable for convenience in adjustment and transportation.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1.
