FOLDING TABLE.

SPECIFICATION forming part of Letters Patent No. 623,794, dated April 25, 1899.

' Application filed April 20, 1898- Serial No. 678,295. (No model.)

To (tZZ whom it may concern:

Be it known that I, HENRY G. LEISENRING, a citizen of the United States, residing at lVayne, in the county of lVayne and State of Nebraska, have invented certain new and useful Improvements in Folding Tables; and I do declare the following to be a full, 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 drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in folding operatingtables; and it consists in the provision of a table of this character the frame of which is made, preferably, of iron or other suitable metal, the top or cover of which is also made, preferably, of metal, and so constructed that all the parts forming a part of the table may be compactly folded for purposes of transportation or for storage.

The invention relates, further, to the provision of a folding table which is provided with head and foot rests which may be held when extended for use at any desired angle and when the table is closed the said rests being adaptedto fold compactly together, as well as the braces and the pivoted legs forming a part of the present invention.

To .these ends and to such others as the invention may pertain the same consists, further, in the novel construction, in the combination, and the adaptation of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts throughout'the several views, in which Figure 1 is an elevation of the table opened out. Fig. 2 shows top in a raised position. Fig. 3 shows the back-rest raised when used as a chair. Fig. 4 is a plan View of the head and foot rests and braces forsupporting same, this view showing the parts in a closed relation. Fig. 5 is a side elevation of the top shown as folded. Fig. 6 is'a bottom plan view of the table folded. Fig. 7 is a detail view showing how braces are connected to rounds or cross-pieces of the table. Fig. Sis a top plan view of one-half of the top of the table with parts closed, excepting theend braces, which are shown only at their pivotal ends.

Reference now being had to the details of the drawings by letter, A A and A A designate the legs of the table, which are made, preferably, of steel or other metal. Fastened to the legs A and A are the cross-braces B and B, and mounted on the upper ends of the said legs is the frame 0, which has an eX- tended portion C, to which is pivoted the head-rest E. The top D is pivoted to the frame 0 at d and when closed is preferably flush with the edge of the said frame. The head-rest E is supported when open by means of'two braces F, (connected by the rod F,) which have a series of notches on their under sides, as shown at f, adapted to engage on the cross-brace G, held between the legs A, as shown. The upper ends of the said braces are pivoted to the head-rest and are adapted to fold over on top of the head-rest when the table is folded. The opposite end of the said top D has pivoted thereto the foot-rest H. This foot-rest is pivoted to an extension of the table-top at H and adapted to fold over on the top of the table when the same is folded and held up by two braces I, which are connected by the rod 1 and rest on the crossbrace Gbetween the legs A. A back-rest J (shown clearly in Fig. 3) is pivoted to the top D, as at J and when said back-rest is not in use it may be folded down so that its upper edges will be flush with the upper edges of said top D, as illustrated in Fig. 2,. which shows the top raised and the back-rest not in use. Pivoted to the back-rest J at j are the braces J',whieh have a series of notches and adapted to hold the back-rest at an angle by means of the notched portion engaging with a rod K, mounted in the frame 0. a This backrest is raised by means of the lug M.

Connecting the legs A and A are the side strips or braces N, two on each side, two of which braces or strips are pivoted at P to the legs A and at their meeting ends carry the rod or round Q, while the outer ends of the second pair are provided with hooks and are designed to engage over a cross-brace carried by the legs A,whereby when the table is desired to be folded the ends of the said side strips connected with the brace carried by the legs A may be unfastened to allow the legs to fold up under the top of the table. Mounted on the said round Q are the diagonally-disposed braees R, the upper ends of which have each a contracted portion R, adapted to fit in an aperture or socket in the braces G and G to make the table more rigid against a longitudinal movement. At the end of the folding or pivoted top D in the center is a spring S, which is adapted to catch under and be retained by the end of the frame 0 in order to lock the parts together. \Vhen the parts are folded together, as shown in the figures of the drawings, buttons T are utilized to hold the interfolding legs and braces, as shown, whereby the use of straps is dispensed with when the table is adjusted in its folded relation. If desired, stirrups of ordinary construction may be fastened to the frame 0 in the usual manner.

In folding the table the head and foot rests are first thrown back on the top of the table. Then the braces supporting the head and foot rests are folded inside of the edges of the said foot and head rests and held in place by means of the button, as illustrated. In folding the legs the ends of the braces N are unhooked from the braces between the legs A, the said braces folded upon themselves and between the legs A, as are also the braces R, which have previously had their upper ends withdrawn from the sockets or apertures in the braces between the legs and when folded under the table-top are held securely in place bymeans of the cross-braces B, B, G, and G, as shown and described. The legs A are first folded under and then the legs A. The cross-braces G and 13 on legs A rest over and on top of the legs A and are held together by the button '1 on cross-brace G.

From the foregoing it will be noted that a table constructed in accordance with my invention will be simple, durable and adapted to be folded within a compact space and may be readily opened out when desired for use,

producing a rigid frame provided with head and foot rests which may be tilted to any desired angle that may be found necessary in the utilization of the table.

On each side of the leg-rest H are notches X, which notches are designed to rest on the projection X on the end of the frame C when the top of the table is lifted, (see Fig. 2,) thus doing away with extra braces to raise the top. The back-rest is pivoted to the table-top D, as at J Figs. 2 and \Vhen down, it is flush with the top and forms part of it. The braces J fold up inside of the back-rest when down.

Having thus described my invention, what Iclaim to be new, and desire to secure by Letters Patent, is

In a folding operating-table, the combination with the frame 0 and legs A and A, pivoted in pairs thereto, of the pivoted top D, the back-rest J pivoted to the latter, and having a lug M designed to be seated in a recess in the top D and frame (J when said back is closed, the projections at the end of said frame, the head-rest E pivoted to said projections, and braces for holding said rest at different angles, the notched foot-rest pivoted to the swinging end of top D, the upwardly-projecting lug X at the end of frame 0 adapted to engage with said notches, of the braces I, the braces N pivoted together at their inner ends, the round Q, one pair of said braces being pivoted to legs A, the free ends of the second pair having hooked ends, of the brace carried by legs A, and engaged by said hooked ends, the braces R pivoted to round Q, with their free ends contracted and engaging in recesses in the leg-braces, and means for holding the table folded, as set forth.

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

HENRY Gr. LEISENRING.
