2 Claims. 1

This invention relates to separable or detachable devices for securing table legs and tops to pedestals and bed rails and the like to posts, and in particular a holding plate with tongue receiving sockets therein, a base plate with tongues extended therefrom and a wedge for locking the tongues in the sockets whereby with the holding plate positioned on one element and the base plate on another the elements may be clamped together with a wedge action wherein play developing in a joint between the elements may be taken up by driving the wedge into the tongues.

The purpose of this invention is to provide a positive locking connection between elements such as table legs and bed rails and supporting members therefore in which a metal to metal contact is obtained so that the joint is not affected by shrinkage of the wood members.

In the usual method of attaching legs to pedestals of tables, and the like the parts are held by wood screws and when the furniture is moved it is necessary to remove and replace the screws. This continuous removing and replacing of wood screws in wood elements causes play so that furniture that is moved several times is not rigid. Furthermore wood shrinks with age and with screws holding one wood element against the other play soon develops in the joint. With these thoughts in mind this invention contemplates a positive metal to metal contact in joints of table legs and tops to pedestals and bed rails'to posts wherein substantially all play due to shrinkage and wear is eliminated.

The object of this invention is, therefore, to provide means for rigidly connecting table legs and the like to pedestals in which the parts may be removed and replaced continually without play developing in the joints.

Another object of the invention is to provide a separable connection for table legs and tops and also for bed rails and the like in which the parts may be separated without removing screws.

Another object of the invention is to provide a separable connection for table legs, tops, bed rails and the like in which means is provided for taking up wear that may develop in the parts.

A further object of the invention is to provide a wedge controlled separable connection for removable elements of furniture and the like which is of a comparatively simple and economical construction.

With these and other objects and advantages in view the invention embodies a holding plate having tongue receiving sockets therein permanently mounted on the table element, a base plate with 2 tongues extended therefrom and positioned to extend through the sockets of the holding plate mounted on another element and a wedge that is inserted through openings in the tongues of the base plate for positively clamping the base plate to the holding plate.

Other features and advantages will appear from the following description taken in connection with the drawings wherein:

Figure 18 is a sectional plan through the looking elements shown in Figures 16 and 17 with the parts assembled.

Referring now to the drawings wherein like reference characters denote corresponding parts the separable keeper or'fastener of this invention includes a holding plate III, a base plate II. and a wedge I2.

In the device shown in Figures 1,; 2-, and3 the holding plate III is provided with countersunk screw holes I3 and a flange I4 extends from one edge.

therein, that extend outwardly from the base plate II. with counter-sunk screw holes as indicated by the numeral I8.- In this design the holding plate Ifl'isalso provided with a short-flange I9 that is positioned in a slot 20 in a bed rail or the like, as-indicated' by'the numeral 2I' and'with this flange positioned in the slot the" holding plate is located on the end of the-rai1 and'securely held in position by the flange. The holding plate is also secured to the bed railbyscrews 22 positioned in the openings I3;

With these parts in position and with thebase plateI I secured to the face of apost 23 by. screws 24, the end of the bedrail isheld against the face fthe post with the tongues I6 extended through the sockets I" and the wedge I2 is dropped into the openings I'I; The'wedge may be tapped lightly if desired and should wear develop in the parts the wedge may be driven further into the openings of the'tongues.

In the design shown in Figures-5-10 inclusive an L-shaped holding plate 25- is secured in a recess 26 in a pedestalZ-I andsockets 28 are-positioned in-the' plate to receive tongues 29 on-a base plate 30. The end 31 of the holding plate 25 is also provided with a socket 32 for receiving the wedge I2.

The plate 25-is also providedwith screw'holes, as indicatedby the numeral 33 and this plate is secured in the recess 26-by screws 34; The base plate 30 is provided with screw holes and this plate is secured ina recess 36 inthe end of a leg 31 by screws 38. v
