UNITED STATES PATENT PETER s. CRAWFORD, or ROGKFORD, ILLINOIS.

TABLE-LEAF SUPPORT.

SPECIFICATION forming part of Letters Patent No. 249,312, dated November 8, 1881.

Application filed May 19, 1881.

To all 'whom 'it may concern Beit known that LPETER S. CRAWFORD, a citizenlof the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Supports for Table-Leaves; and I do hereby declare the following to be a Y yfull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying l drawings, andto the letters or figures of reference marked thereon, which form a part of this specification. Y j

The object of this invention is to simplify the device for supporting the leaves of tables, and at the same timehave the table-leaf,when raised up and supported, secure against any j danger of being accidentally made [to drop,

and thereby break what may beupon it; and it consists in the construction of theparts forming the device, as will be fully ,hereinafter` described.

In the drawings, Figure l represents the underside view of a table-leaf when raised and the `device in position to support the leaf. Fig. 2 represents a side view, partly in section, on line a.' ,fr of Fig. 1. Fig. 3 represents a transverse broken sectional view ot' Fig. 1 on line y y, and Fig. et represents the upper side ofthe tilting catch.

A represents the frame of a common fallleaf table.

B represents the bed, resting on frame A.

C represents the fall-leaf as hinged in the usual manner to bed B.

D represents the hinged holding-brace or support, and hinged at d to frame A, and has projecting lugs d near its outer end on opposite sides, the forward faces of which are at, or nearly at, right angles with the under side of lip df, at the extreme outer end of brace D, as seen in Fig. 2, at d".

. E is a slotted guideway, screwed fast to the under side of the table-leaf by the screws e and e.

E shows the longitudinal. slot in the under side of the guideway, and at the outer end there is a narrower slot, e, in which the hold- 5o ing-screw e is inserted, to hold the outer end (Model.)

of the guideway fast to the leaf, and while it so holds the guideway firmly to the leaf, and the wood is not thoroughly seasoned, will allow the wood to contract without in any way disturbing the relative position of the guideway with the brace-support, which is free to have its outer end slide in the guideway.

- f f are inwardlyjprojecting anges on the under face ofthe guideway, and on each side of the longitudinal slot E', the office of which is to keep the outer end of the brace D, by its projecting lugs d' ,from falling out of the guidewayin its reciprocations in raising or dropping the leaf, as seen in Fig. 3.

Gr is a tilting catch, and acts to catch the end of the brace and hold it rm when the leafl C is raised to be on the same plane with the bed of the table. It is slotted to fit transverse# ly in openings in the sides of the guideway E, as seen in Fig. 1, the parts g and g"`project ing on opposite sides thereof.

g is a rounded projection on catch G, on the side next the table-leaf, forming a kind of fult crum to the catch, and upon whichit tilts, the bearingsin the openin gsin the sides ofthe guideway beingsuch that the outer points of theopenings `will always bear upon the outer edges of the part-s g and g, while the inner parts ofthe openings are deeper, which cause the inner edge of the catch to freely recede from the table-leaf when free, and when the brace-support, with its outer end constructed as described and shown, is inserted in the guideway, and the guideway and the brace-support firmly attached to the parts of the table, and the leaf is raised, as seen in Fig. 2, the brace will have passed over the inner edge of the catch, pressing it down as it passed, and as soon as relieved from such pressure the edge ofthe catch springs away from the table-leaf before the abutting part of the brace-support and locks the bracesupport firm in position to hold the leaf on a plane With-the bed B.

To release the catch and let the leaf C fall by its own weight, press the thumb part g' of catch G until it tilts out of contact with the outer end of the support D, when the leaf is free to swing on its hinges and fall into an up right position. By simply raising the leaf the I lay no broad claim to a slotted gnideway In testimonyT whereof I affix my signature [o or to a brace-support guided by a guidewayin in presence of two Witnesses. its operations to support a table-leaf; but

What I do claim as my invention is- PETER S. URAVFORD. 5 The rocking or tilting catch G, having the fulcrum-projection g and projecting thumb Witnesses: part y', in combination with the gnidewzty E R. F. CRAWFORD, and support D, constructed substantially as J. B. CRAWFORD. and forthe purposes described.
