UNITED STATES Vllfrisivr .Orino-ne WILLIAM JOSEPH DEVERS, OF PROVIDENCE, PENNSYLVANIA, ASSIGNOR OF ONEHALF TO WILLIAM T. OMALLEY,A OF SAME FLAOE.
EXTENSION-TABLE.
SPECIFICATION forming part of Letters Patent No. 283,582, dated August 21, 1883.
Application filed April 12, 1883. (Model.) i V .To all' whom t may concern,.-
Be it known that I, "WILLIAM J. Dnv'nns, of Providence, in the county of Lackawanna and State of Pennsylvania, have invented anew and ImprovedExtension-Table, of which the following isa full, clear, and exact description- The object of the invention is to improve extensiontables, as hereinafter described, and pointed out in the claim.
Reference is to be had to the accompanying drawings, forming part of this specification, in whichsimilarletters of reference indicate corresponding parts in both the iigures.
Figure 1 is a plan view of my improved table with the cover removed, and Fig. 2 a
transverse section on line as of Fig. 1.
I make the extension-slides ofthe frame to consist of the two parallel bars c for one end, placed a suitable distance apart, and having no grooves b in the confronting sides, and the `single bars c, attached to the other end and sliding between bars c, and having ribs cl, that run in the grooves of bars a, thus making a substantial sliding or extension frame that will `2 5 not sag between the supports. In this case I have represent-cda central leg, e, for support of the frame at the middle by means of the cross-bar f; but with this form of extensionfrarne this leg e may be dispensed with.
3ol To slide the table apart or together by the Aropes g and h, I have one bar, z', attached to end j of the table, to which bar the ropes are attached at It, from where rope g passes over a pulley, Z, which in this ease is arranged in 3 5 one end of a lever, m, pivoted to bar o at p, but which may be arranged directly on said bar, in case lever m is not used. The bar o is attached to the other end, q, ci' the table, so
vthat it will be seen that by pulling rope g the table will be extended, and by pulling h it will 4.o be shortened. The object of lever on is to act on a pin, skfronl the fulcruni p with greater force than the direct pull of the rope will effect,
to overcome the tendency of the parts to stick together and facilitate the starting of the eX- tension.
For a binder to cla-nip the extension-bars n and d together and fasten them in any position,
I employ the bar t, fixed on the pivot u, and having a push-and-pull rod, n, connected to it to swing it, so as to cause the ends to press inside bars c against bars c and outside .bars
a, the latter being made fast to the cross-bar f, but the inside bars o and the bars c being unconnected. The stop-pin prevents the 5 5 binder t from being swung too far.
Having thus described niy invention, whatI claim as new, and desire to secu-re by Letters Patent, is-
An extensioirtable having one stationary 6o and one movable section, the stationary section being provided with parallel side bars, a.
a., and bar o, and the movable one with the bars c 'i c, in combination with the ropes g Il, attached-to bar i, the levernz., fulcrumed upon the bar o, as set forth, the pulley Z on onecnd of said lever, and the pin .s on said bar i, as shown `and described.
