IMPROVEMENT IN TABLE-LEAF SUPP-ORTS.

Specification forming part of Letters Patent table leaf support at a small cost, which can be' easily applied, and that will be a reliable support. lo this end I have constructed and arranged the device represented in 'the accompanying drawings, in which- Figure l is a transverse sectional elevation of a portion of a table, consisting of one leg', a portion of the frame and top, and leaf, with my improved leaf-support in place. Fig. 2 is a view ot the under side of a transverse centrai portion of one side of a table, with the leaf-support in place.

In the drawings, A represents a corner leg of a table, into which the end piece B and side piece O are framed, in the usual manner, and constitutes a corner portion of altableframe. D represents a portion of the fixed top of a table secured to the frame, and E represents the falling leaf, jointed andhinged to the iixed top l). A triangular piece, F, is secured to the topD and side piece C, in the inner angle formed by these parts, and serves as a brace to the side piece C. These parts are substantially the same as now found in the trade and in common use. a is a metallic brace of any suitable form, provided atone end with T-formed journals b, fitted in hinge form in plate c, secured near the lower edge ot' side frame C, in such a manner as to permit its outer end to move up and down in a vertical plane. The outer end of brace a is fitted to engage the catch d on catch-plate e, which is let into, and is secured in place on, the under side ot' the falling leaf, and serves to hold the leaf in an extended horizontal position. The catch-plate e is provided with an oblique arm, f, projecting from the plate at bout right angles to the brace a, and is inside No. 184.636, dated November 21, 1876; application filed May 15, 1876.

of the catch d. The oblique arm f is slotted centrally lengthwise, to receive the free end ofthe spring h, and permit it tor play freely in the slot. The catch end of brace a is provided with an L-formed lateral projecting arm,

t', which, when the leaf is raised,comes in contact with the arm f, and prevents the leaf from rising above a horizontal position, tov

prevent undue strain upon the hinged joint. It is a wire spring, of the form represented in the drawings, secured to the under side of the falling leaf near its outer edge, its free end overlapping` the lateral projecting armi, and is received in the slot in arnlf. The force of the spring holds the outer end of braced in contact with the catch d. 7c are studs projecting from the lateral arm f, and rise one on l each side of the spring h, Iand serve as guides to hold thebrace in position relatively with the spring, andV permit it to slide thereon in raising and lowering the leaf.

To lower the leaf E, sufficient force will be required to overcome the force ot' the spring h, so as to disengage the brace a from the catch d, when the leaf will drop into the position represented in the dotted 'lilies in Fig. 1, the brace a sliding between the leaf E and spring h, being held in position on the spring by studs k.

To x the leaf E in the horizontal position, it will only require the leaf' to be raised 'to the position, when the brace a will be forced by the action of the spring to engage the catch b, which will hold the leaf in the required position. v

I claim as my invention- The hinged brace a, spring h, and catchplate e, the spring operating to force the brace to engage the catch, and serving as a guideway, on which the brace slides in raising and lowering the leaf, these parts constructed, arranged, and'oper'ating substantially as and for the purpose hereinbet'ore set forth.
