Application August 10,1931, Serial No. 556,288 Renewed September 15, 1933 2 claims. (cl. fia-'1175) This invention relates generally to .extension tables, more speciically to a slide construction whereby companion sections of the top will be simultaneously moved an equal distance in opposite directions by pulling or pushing on either section. f

The principal object of the present invention is to provide a slide construction for the purpose described which will occupy and operate in but little space, yet permit a wide separation of the companion sections of the vtable top.

Brieiiy stated, the invention consists of a base rail upon which is slidably mounted a pair of oppositelydisposed slide bars. A lever is pivoted midway of its ends to the rail; the opposite ends of said lever being connected to the slide bars by links` to which are connected a secondary lor auxiliary lever disposed parallel to said pivoted lever.

Other objects and advantages will be apparent from the following description, reference be-A ing had to the accompanying drawings, in which; Fig. l is a bottom plan View of the extension table with the top sections in closed position.

, Fig. 2 is a section taken on line 2-2 of Fig. l in the direction indicated by the arrows.

Fig. 3 is a section taken on line 3-3 of Fig. 1. Figs. 4, 5, .6, and 7 are fragmentary bottom plan views showing various positions assumed by the working parts 0i the improved slide construction during opening of the table top sections.

Referring more speciiically tothe drawings, 10 and l1 designate end and side strips respectivelyof a table frame 13 upon which is mounted a top 14 formed of companionsections 15 and 16, the frame being supported in the usual manner by legs 17.

The slide constructions generally designated at v18 and 19 are suitably spaced apart and .iounted in the frame `in parallel relation.

Slide constructions are of exactly the same construction, each of which include a base raill 20 extending between and secured to the end stripsvlO. y

, Mounted on each side of the kbase'rail 20 are slide bars 22 and 23 which in turn are secured by screws'or the like 24 to the underside ci the companion sections 15 and 16 of the table top. In the present instance, slide bar 272 is secured tosection 15, whilebar 23 is secured to section 16. -The slide bars are provided with tongues 24 which slidably engage grooves or guideways formed in the side faces of the base rail.

A lever 26 is pivoted midway of its ends on a pin or the like 27 to the underside ofthe base rail, the pin lbeing preferably located at a point half way between the end and side faces of said base rail. M.

Pivotally connected to slide bars 22 and 23 rey spectively by Vscrews or the like 28 and'29 are 60 links 30 and 31, which in turn are connected by pivot pins 32 and 33 to the opposite ends of lever 26. Link 30' extends beyond pin 32, and is `connected in a like manner, as indicated at 34, to one end of an auxiliary link or bar 35, the opposite end of which is connected to link 31 at a point indicated at 36 between pin 33 and its piv` otal connection 29 to slide bar 23. v

Auxiliary link 35 is disposed in parallel relation to lever 26, and serves to permit a wider separation or extension of the top sections thanv would be possible with a single pivoted lever of the-same relative size.

Assuming that the top sections are being opened or extended, lever 26 turns'on pivot 27 75 through links 30 and 31 from theposition shown inFig. 1 to that shown in Figs. 4 and 5.

During the above interval, the lever 26 and links 30 and 3l serve to move the sections.

Auxiliary link 35 now coacts vwith the lever 26 to g@ -move the sections from the position shown in Fig. 6 to fully open position as shown in Fig. '7. From the foregoing, it will be readily seen that when either of the top sections 15 or 16 are manually moved the opposite sections will move a corresponding distance in the opposite direction.

I claim: f' l 1. A slide construction of the character de- 9@ scribed comprising a rail, a pair of slide bars slidably mounted 'on each side of said rail, a lever When separated, one or more loose leaves may pivotally mounted midway of its ends on said rail, a link pivotally connected to each of said slide bars and to the outer ends of said lever,

and an auxiliary link connected to said links in parallel relation to said lever.

2. A slide construction ofthe character .de-

scribed comprising a rail, a pair of slide Ybars slidably mounted on each side of said rail, a lever pivlite otally mounted midway of its ends on said rail, a link yconnected to said lever adjacent one end thereof and to one of said slide bars, asecond link connected to the other of said slide bars and to the opposite end of said lever, and an auxiliary link connected` to the outer end of said rst link andA nection to said lever and slide bar.
