l Application filed February 27,1904. Serial No. 195.641.

Be it known that we, Tnoinas SrU'rzMAN and AND1-inw A. Donny, citizens ol the United hltates, residing at Scranton, in the county of Lackawanna and State ot Pennsylvania, have invented certain new and useful Improvements in Extension-Tables, ol'l which the 'following is a specilication.

'lhe purpose ol" our invention is to provide an 'extensiointahle which is siinple, strong, and comparatively lig'lit in construction and in which provision is inade tor sui'iporting the table at the center by ineans oi a leg` which is connected to the table in such manner as to remain in a central position when the table is closed or extended.

The details of our invention will he pointed out in the following' speeilication, taken in connection with the accompanying drawings, in which- Figure l is a bottom plan view of the tabletop and extension-frame, showing' the table extended in full lines, its closed position being indicated in dotted lines. Fig. 2 is a section on the line 2 2 et Fig. l. Fig. 3 is a sectional view on the line 3 3 of Fig. 2, showing the centi'al leg ol the table and connected iliarts; and Fig'. et is a horizontal section taken on the line oli' the slots in adjacent side hars ol'l the Vlrailie-sections.

lhe extensible traine ol: the tahle comprises two inain parts A and B, upon which the top pieces (l and lf), respectively, ot' the table are secured. 'lhe part A ol the Ytraine consists, as shown, olf two parallel nietal angle-hars it and a', L shape in cross-section, said hars extending longitudinally oi the table, and a siinilai'lyloi'ii1ed cross-har a, secured to the outei' ends ol said parallel hars h v angle-pieces l. W hen in position, the wings or V[langes 2 oi the angle-bars extend in the saine horizontal plane, and the part C ot' the table-top is secured to these i'langes by screws 3 or other suitable fastening' devices passing through the flanges The wings or ilanges al extend downwardly in vertical plane.: The depending' ilanges of the side bars a and 1/ are each provided with longitudinal slots 5, extending throughout the greater portion el" their extend inwardl).v toward one another, and

these hars are so arranged that their vertical Vflanges T may nieve between and in sliding' Contact with the e 1'i'esi )oiuliiig llanges i,lof the hars l and it. 'llie V[langes 7 are provided with longitudinal slots 8, which register with the slots 5 in the hars (l. and c. The inner end oi' each side har is provided with a holthole 9, in which is secured a holt or stud Alt), which projects through the slot in the opposing side har. The two sections olE the eXtension-liran'ie are thus` connected together hy the bolts or studs, so that they cannot he pulled apart and vet may he inoved longitudinally to open oi` close the table. The legs ll at the ends ol the table are'lori'ned et inetal tubing', and their upper ends are threaded and lit within littings 19., having threadinl sockets 13, which fittings are secured to the end hars (1.2 and if' ol the extension lralne hy holts l-l* extending' through flanges 1,5 upon the litting's and through the vertical flanges ol the hars/lf and 6". A ceiiter leg lo, also made ol nietal tuhing', has a screw-threaded upper end, which lits within a socket 17 in a ittiug lil. This lit ting is provided with flanges 13, extending horizontally in opposite directions and hy which it is secured to the center oll a llat inetal or wooden har 1S), exteinliug' longitudinally heneath the table-top in sliding engagen nient therewith and torniii'ig a distance-piece which abuts against the vertical llanges ol' the end bars (t2 and when the tahle is closed to keep the leg' A16 in a central position, as shown in dotted lines, Fig. l.

The l'itting lll is in'orided with a transverse opening, and a metal tube 2U issecured within said opening and projects to equal distances beyond the sides ol the litting. '.lhe ends otl the tube abut against the vertical flanges T ot the hars and Zi', and a holt 2.1. extends through said tube and through the slots in all of the side bars of-the extension-frame. rThis bolt, as shown, is provided with a square portion 21 near one end, which prevents the bolt from turning in the guide-slots, and with a wing-nut 22 at its opposite end for the purpose of clamping the side bars against the ends of the tube 20. The tube is thus securely held in position and forms a distance-piece, by means of which the leg 16 is held midway between the sides ot' the table. The leg 16, being secured to the distance-pieces at their intersecting or crossing' point, is held rigidly in an upright position, the piece 2O preventing lateral inclination of the leg and the piece 19 preventing inclination of the leg longitudinally of the table.

To length or shorten the table, it is merely necessary to loosen the wing-nut 22, and the extension-framemay then be opened or closed. The distance-piece 19 has a bearing against the parts C and D of the table-top in the most extended position of the table, as shown in full lines in Fig. 1. Then the table is closed, the leg 16 is centered in a longitudinal direction by the abutment of the bars a2 and 7/2 against the ends ot' the distance-piece 19, said bars forming stops for the distance-piece, and when the table is extended to its full length the leg is centered in a longitudinal direction by the engagement of the ends ot' the bolt 21 with the end walls of the slots in the side bars of the extension-frame. Then desired, the center leg and distance-pieces may be removed by removing the bolt 21, or any of the legs may be removed by unscrewing them from the sockets in which they are held.

Having described our invention, what we claim, and desire to secure by Letters Patent,
