TO ALL WHOM `IT MAY CONCERN: z

Be it known that I, GEORGE KUHLMANN, of the city, county, and State o f New York, haveinvented a new and useful Improvement in Tables; and I do hereby declare that the following is a. full, clear, and exact description of theconstruction and operation of the same, reference being had to the annexed drawing, making a part of this specification, in which- A Figure 1 is an end view of the'table as it appearswhen closed.

Figures 2 and 3' are, respectively, end and side views when the leaves are extended.

Figure 4 is an enlarged horizontal View of the spring-catches a a, Svc., shown in figs. 2 and 3.

Construction.

The centre leaf b is supported by the ends c c, which are'holloxv panel-Work, and are themselves secured to the feet @Z d, tbc., and are'longitudinally braced by the cross-piece e, connecting them, the whole being made of any suitable wood, and of any desirable design. The lower leaf,f, has openings made in it of the proper shape, andsuicient distance apart to allow it to slide freely up and down on the end pieces c c, and. is supported and moved by the cords g g, Snc., which pass over the pulleys' h h, Snc., and are secured to the en'd pieces z'z', which' are the supports for the upper leaf. The centre leaf is made thicker than the others, to accommodate the springcatches a a, which are made of brass or other suitable metal, and are shown, on a large scale, in iig. 4.

. Operation.

To extend the table, elevate the leaf k with the hand, and the cords will pass over the'pulleys and allow the leaff to descend; When the leaf k has been elevated to a certain point, the catches a a will enter the recesses', made in the sides z'z', to receive them, and thereby arrest the motion, and sustain any desirable weight.

To close the table, place the finger in recess m, as shown in tlg. 2, 'and pull. The effect will be, the catches a a will be removed fromthc recesses, and the weight of the leaf k will cause it to descend, and, at the same4 time, by the action of the cords over the pulleys, elevate the leaff, until both resume the position shown in iig. 1.

What I'claim as my invention, and desire, by Letters Patent, to secure, is The application, to tables, of the arrangement of the cords y g, Svc., pulleys 71, h, Etc., and spring-catches, shown by tig. 4, all used for extending vertically, and supporting, 'when extended, the leaves f and k, as hereinbefore described.

GEORGE KUHLMANN.
