UNITED STATES HENRY IMHOE, on LooKroET, NEW YORK.

IMPROVEMENT IN TAELE-LEAF SUPPORTS.

Specification forming part of Letters Patent No. 137,925, dated April 15,1873; application filed November 29, 1872.

To all whom it may concern:

Beit known that I, HENRY IMHOF, of Lockport, in the county Aof Niagara and State of New York, have invented a new and Improved Table-Leaf Support; and I do hereby declare the following to be a full, clear7 and exact description thereof which will enable those skilled in the art to make and use the same, reference bein g had to the accompanying drawing forming part of this specification, in which drawing- Figure 1 represents a side View of my invention. Fig. 2 is a plan or top View of the same. Fig. 3 is a longitudinal vertical section of the hingejoint. Fig. 4 is ahorizontal section of the same in the plane .r x, Fig. 3.

Similar letters indicate corresponding parts.

This invention relates to the construction of the hinge-joint which unites the ily with the frame oi' the table, said joint being composed of a U-shaped yoke which is secured with its central part to the end of the iy, while its arms straddle a projection formed on a board attached to the frame of the table, being connected thereto by a pivot or pivots in such a manner that a firm and durable connection between the vfly and the frame of the table is obtained, and that the joint can be readily kept free from impurities.

In the drawing, the letter A designates my iiy, which is made of wood equal in width to the width of one of the sides of the frame B ofthe table to which said y is to be attached. To one end of my iiy is secured a Ushaped yoke, C, which `is by preference cast ot iron, brass, or any other suitable material, and which is rigidly fastened to the fly by means ofscrews c, best` seen in Fig. 3 ofthe drawing, said screws being made to pass through the ceutral portion ofthe yoke. The arms b b of the yoke C straddle a projection, c, which is formed on the end of a board, D. This board is equal in width and in thickness to the iiy, and it is permanently fastened to the frame of the table, its end being cut down to form the projection c. The connection between the arms b and the projection c is effected by pivots d d, which may be made in the form of wood screws, as shown, or, if desired, a single pivot may be made to pass through both arms and through Ithe projection. The edge or end ot' the projection is rounded oft' to form the seg ment ot' a circle described from the center ot' one of the pivots d, and it ts into a cavity formed in the inner edge of the central part of the yoke C, (see Fig. 4,) so that when the iiy is turned ou its pivots the end of the projection c will work nicely in the cavity of the central, part of the yoke. By these means a neat and durable joint is produced between the fly and the frame of the table, and the Hy is not liable to break off or to work loose; and, furthermore, if it is desired to clean the table the ily can be readily taken off and all impurities which may wolk themselves into the joint can be easily removed.

I do not claim forming the end of the iiy with tenons which tit into the mortises formed in the end of an independent board, the two being pivoted together by a pin passing ver- A tically down through the same, as such are old and well known; but

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

In a table-leaf supportth'e yoke C formed with the `arms b b and curved seat, and with pin or screw openings at right angles to each other, as set forth, in combination with the ily A and the board D, having the projection c, all constructed as herein shown and described.

HENRY IMHOF.
