EXTENSION-TABLE.

SPECIFICATION f0r1 ning part of Letters Patent No. 543,7 94, dated July 30, 1895.

Application filed March 15, 1895,

To all whom it may concern.-

Be it known that I, JOHAN ZAL1KowsKI',a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Extension Tables, of which the following is a specification.

This invention relates to improvements in extension-tables,'and more especially to that class of such tables as is used for dining purposes; and it consistsin certain peculiarities of the construction, novel arrangement, and

operation of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

The objects of my invention are, first, to provide an extension-table which shall be simple and inexpensive in construction, strong and durable, and easily and readily extended or contracted, and, second, such a table in which the leaves or parts to be used for the extension thereof are always conveniently at hand,-so as to be placed in the proper position.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings,

Figure l is a longitudinal sectional view of one form of: my table, showing it in an extended position. Fig. 2 is a cross-sectional Fig. 3 is a longitudinal sectional view of the upper portion of: the table, showing it closed and a modification in its construction. Fig. & is a similar View showing the same in' its extended position. Fig. 5 is a bottom plan view, partly in traction taken on line 11 ll of Fig. 3, showing the method oi. securing the legs to the table. Fig. U is a sectional view taken on line 12 12 of Fig. 5. Fig. 7 is a detail view in perspective of one of the securing;

screws for the legs. Fig. 8 is a like view or the socketpieet to receive said screw. Fig. 0 is a cross-sectional view of the extensible slides detached from the table, showing the Fig. 10 is a detail perspective view of one of the castings for connecting the slides, as shown in Fig. i). 11 is a perspective view of one of the hinges used on the table-top .of the hinge, showing it resting on the top of thejrame a v have been extended to any desired distance Serial No. 541,845. (No model.)

shown in Figs. 3 and 4, illustrating said hinge in an open position; and Fig. 12 is a like view closed and detached from the tabletop.

Similar letters refer to like parts throughout the different. views of the drawings.

A represents the top of my table, which is secured on a suitable frame a, mounted on legs a, of the ordinary construction and style. As shown in Fig. l of the drawings, the top A is divided into two sections, which sections are firmly secured to the frame ct, which is likewise divided into two sections, so that when the sections of the top are separated the leaves B may be placed between the same and will rest on the extensible or slide-rails O, which pieces are provided with'longitudinal grooves or slots 0 for the reception and operation of suitable castings D, whicharein 7o cross-section ofthe shape of the grooves or slots in the extensible or sliding rails Cwhe'ir the same are united together," as shown in Fig. 9 of the drawings 1 i The castings D have at one of their ends a plate or extension (I, provided with an opening to receive a screw d to be used for securing it to the end of its respective slide or rail, so that the other end thereof will fitand operate in the groove 0 in the adjacent-sur- 8o face of one of the otli'e'rslides O or rails. This construction of the slide-pieces C and'thc castings D attached thereto secures thc'slide pieces or rails together in such a manner that theyrnaybeextendedlongitudinally,asshown in Figs. 1 and 4 of the drawings.

In Figs. 3 and dot the drawings I have illustrated another modification, in which the tabio-top .A is provided at its center with a hinge or hinges a, which allows the said top 0 to be closed together, as shown in Fig. 3, or thrown open, as illustrated in Fig. 4, thus which may by means of the sliding rails G, which arc' 5 preferably employed in said construction.

By the use of my hinge (illustrated in detail in Figs. 11 and 12) it is evident that when the top A or any of the removable leaves to which it may be applied is folded together, as shown in Fig. 6, it will present a smooth outer surface, thus preventing any engagement thereof with the table -cloth. 'lhis hinge is composed of two pieces a which are provided at their inner ends with enlarge ments a, which enlargements have formed therein recesses a for the reception of the links 0?, which are held in position by means of bolts 0, passed through suitable openings in theenlargemcnts (L6 or inner ends of the pieces a, which are secured to the pieces constituting the table top orleaves by means of screws or otherwise. The casting or uniting piece D shown in Fig. 10,'and which I prefer to use in the sliding rails, is formed with a. vertical rib cl; having at its upper and lower portions an enlargement (i to tit and operate within the slot or groove 0 of the sliding rails.

By reference to Figs. 3 and 4 of the draw ings, it will be seen that the middle log a of thetable is secured at its upper end to a cross piece I), which uuites'thc pieces I), which are located transverse! y with the table-frame and are secured at each of their ends to one of the sliding rails 0, thus allowing said middle leg to be Fig. 3, when the table is in its compact form.

The legs and that portion of the frame located at the end of the table-top to which the hinges a are attached are movable relative to the table-top, so that the same may be extended to the position shown in Fig. 4 of the drawings, which operation will also extend the middle legnntil it is directly under the hinged part of the top, as illustrated.

In the modification just above described I e do not use separate leaves, as in the construction previouslyset forth, but simply a top hinged as specified. p

In Figs. 5 and 6 of the drawings 1- have shown the method of connecting the supporting-legs a of the table to the table-frame, which consists in securing to the end piece a of the frame near each. corner of the table a triangular piece F, which is provided with a moved to the position indicated in recess f to receive one corner of the leg of, which portion of said leg is provided with an opening g, within which is secured a socketpiece G, which engages with a set-screw H, which is passed through the angular piece F, as shown in said figures. This method of securing the legs to the table allows the end portion thereof to be moved independently, ii: desired, of the side pieces a" of the table'- frames which may besecured'to the top it 110- v sired. 1

Havin thus fully described my invention, what I c aim as new, and desire to secure by Letters Patent, is-- i 1. In an extension table the combination of a frame made in sections, with a series of sliding-rails or pieces at each side of theframe, said rails being united together so as to be extensible longitudinally, a top on the upper surface pf the frame, supporting legs at each corner of the same having the openings 9, provided with the socket-pieces G, the angular pieces i secured to the ends of the frame and the set-screws H, to unite said pieces andlegs, substantially as described.

2!. In an extension of the frame made in sections, with a series of sliding rails at each side of the frame, said table the combination rails having the grooves c, in their adjacent.

surfaces, the uniting pieces I), having the enlargcments d, to o crate in saidgrooves and. seen red to the .endsof1 the rails, cated on the upper surface oi theframasnpporting legs at each corner of the frame, the same having the openings 9, provided with the spcket pieces G, the frame pieces 1",se' cured to the ends of the frame, and the setscrews 11, to unite said pieces in the legs, substantially as described.
