TAB LE-LEAF S U PPO RT.

SPECIFICATION forming part of Letters Patent No. 407,812, dated July 30, 1889.

Application filed December 22, 1888. Serial No. 294.392. (No model.)

j To all whom it may concern.-

' venient part of the structure, and of a clip secured to the under side of the leaf having a recess or notch to receive the free end of the brace, and a spring-actuated arm which so holds the brace with respect to the clip that the brace cannot accidentally lose its locked position, and yet can be freely disengaged, as will hereinaftermore fully appear. 1n the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresp on din g parts, Figure 1 represents an inverted perspective view of a portion of a table, a table-leaf, and my improved support applied thereto; Fig. 2, an elevation of the same parts, showing the leaf in a pendent position; and Fig. 3, a detail sectional view of the clip and arm.

Letter A designates a portion of a tabletop, and the letter B the table-rail. To the former is hinged or otherwise flexibly connected the table-leaf C, the connection being such that the leaf can readily be let down to a pendent position to contract. the compass of the table. A plateD is secured to the rail or other convenient part of the table, and has pivoted between two cars formed .thereon a rod E, constituting the support proper. This rod at its free end is provided with a lateral turn or projection which is adapted to fitinto the notch or recess F, formed in a metallic clip G, secured to the under side of the leaf. A bent retaining-arm His pivotallymounted in this clip, and a spiral spring is placed around its pivot-pin I, with one extremity bearing upon the clip and the other against the arm, so as to press the free end of the arm normallytoward the leaf. The arm, near the middle thereof, is given an angular turn, so as to stand substantially crosswise of the rod E, and is'provided with an opening of sufficient size to allow the rod to readily inove back and forth therein when theleaf is raised and lowered. In doing this the arm moves somewhat on its pivot, so that its free end will accommodate the varying distances which the adjacent part of the rod occupies with respect to the leaf, by reason of the eccentricity of the pivotal points of the leaf and rod. The function of the arm is to so hold the rod and press it toward the leaf that it will automatically drop into the notch in the clip G to lock the parts, the spring-pressure of the arm insuring this locked engagement and the pivotal mounting of the armadmitting of the rod being disengaged from the notch by easy manipulation.

Aside from the usual hinge, my device consists of but five main parts, being the clip, plate, rod, arm, and spring. It is cheaply manufactured, of ample strength, of great durability, of easy application, and ready and convenient manipulation.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

In a table-leaf support, the combination, with the leaf, of a clip secured thereto and having a recess in one side, a spring-actuated armpivoted in the clip, the free end of which is bent to one side of the clip and has an opening adjacent to said recess in the clip, and a bar pivoted to a fixed portion of the table and extending through said opening in the arm, and having a lateral projection at its outer end adapted to engage the recess in the clip to support the leaf in a horizontal position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
