TABLE-SLIDE.

SPECIFICATION forming part of Letters Patent No. 402,967, dated May '7, 1889.

Application filed March 27, 1886. Serial No. 196,749. (No model.)

To all whom it may concern.-

Be it known that I, SMITH PRATT, a citizen of the United States, residing at Granville, in the county of Licking and State of Ohio, have invented a certain new and useful Improvement in Table-Slides, of which the following is a specification.

My invention relates to improvements in table-slides used in the construction of extension-tables; and the objects of my invention are, first, to produce slides for extension-tables of neat and simple construction; second,

to provide the same with suitable means for limiting the sliding distance, and to construct the same at a low cost of manufacture. I accomplish these objects in the manner illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of my improved slide. Fig. 2 is an end View, and Fig. 3 is a transverse section showing the slides closed.

Similar letters refer to similar parts throughout the several views.

a, b, and 0 represent the slide-bars, which,

when connected as hereinafter described, are fixed beneath the'table-top in the usual manner. Each of the bars a and Z) is cut away on one side to form a central dovetailed projection, (1, extending, the length of the bar. These dovetailed projections are respctivcly made to fit loosely into correspondinglyshaped grooves, e e, cut into the sides of the bars I) c. In the center of the bottom of each of the grooves e is formed a second longitudinal but smaller groove, 70, which extends within a short distance of each end of the bar.

In the bars a b are respectively fixed vertical stop-pins h h, each of which projects sufficiently below the surface of the dovetailed projection to rest in the groove is beneath. These stop-pins h h are inserted through the bars after the latter have been connected by means of the grooves e and projections d, and are so located that when one of the said pins rests against one end of the groove is, in which it slides, the end of the bar in which said pin is fixed and the end of the bar immediately adjoining will be flush.

It will readily be seen that the parts above described may be easily and cheaply formed by suitable machinery, and that the bars having been connected by inserting the dovetailed projections into their corresponding grooves, in which they are allowed to slide, and the stop-pins having been inserted, a connection of the parts is formed which will admit of easy extension and prevent them from becoming entirely disconnected.

Although the above description has been made on a basis of three bars, the same principles of construction may be made to apply to any desired number.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

In an extension-table slide, the combination of the extension bars having on one side thereof the longitudinal dovetailed projections adapted to slide within the corresponding grooves, e, of the adjoining bars, with vertical projecting stop-pins adapted to slide in the smaller grooves, k, substantially as and for the purpose specified.
