' CHICAGO, ILLINOIS EXTENSION TABLE Application filed January 29, 1930. Serial No; 424,395.

My invention is an improvement in tables and more particularly to that type commonly known as refectory tables of the class having extension leaves normally housed under the main top and slidable horizontally and verti cally to extended position coplanar with said top.

The principal object of my invention is to provide that special type of extension tables in which the leaves are guided and supported by inwardly projecting bars or runners with simple and efiective means which provide for the required movements of the extension leaves and firmly support them in extended position on a horizontal plane with the main top.

With this principal object in view my invention has particular reference to a metal fixture attached to a rail of the supporting frame of the table and having a suppoi ting member cooperating with a pin projecting from the runner and engaging said fixture for holding the leaf extended, said fixture being preferably in the form of a hook to receive the pin when the leaf and runner or runners to which it is attached are slid outwardly and raised vertically to extended position on a line with the main top; all as hereinafter fully described and claimed.

In the accompanying drawing Figure 1 is a vertical sectional view through the upper part of an extension refectory table showing the application of my invention, the extension leaves being in housed position. Fig. 2 is an enlarged sectional view of one side of the table with the leaf in extended position.

Fig. 3 is a similar view with the leaf in furthermost position for engagement with the supporting fixtures.

Fig. 4 is a view of the fixture attached to a rail of the supporting frame of the table, and

Fig. 5 is a detail view of the fixture in side elevation.

My invention may be applied to any type of table, and for the purpose of illustration I have shown it in connection with a refectory table having a box frame comprising sideand end rails 1011 supported by legs 12 with a center rail 13 on which rests the crosspiece 14a extending between the side rails 1010 and supporting the top 1 1 which bears at its ends on the side rails, it being observed by reference to Fig. 3 that the side rails of the supporting'frame are cut away beyond the opposite ends of the crosspiece and the end rails 11 similarly cut away to receive the extension leaves 15 in housed position below the opposite ends of the top, and that so the extension leaves are carried at the outer ends of bars or runners 16 working in slots 17 and 18 in the end rails and center rail respectively, said runners being of such length as to maintain engagement with the center rail in the extended position of the leaf which it supports. The width of the slots approximate the thickness of the leaf supporting bars or runners and as the latter slide in said slots in the movement of the leaf to extended 7@ and housed positions the depth of the slots correspond with the angle of inclination of the supporting bars or runners, in the present instance the under side of each runner having a depression 19 providing for a slight lowering of the outer end of the bar or runner for the engagement of a pin 21 on said bar with the supporting fixture hereinafter described.

For supporting the leaves in extended position I provide a metal fixture 21 which is atso tached to the inner side of the end rail 11 at one side of the slot 17 therein, said fixture having an inwardly projecting member with which the pin 20 on the runner 16 engages for supporting the leaf carried by said runncr on a horizontal plane with the top of the table. In the preferred form of this fixture it comprises an attaching plate 22 from one side of which projects a vertical rib 23 extended outwardly at its upper end in the form of an inturned hook 24: the bill 25 of which is spaced from the rib and provides a depression or seat 26 at the inner side ofthe bill to receive and support the aforesaid pin projecting from the runner carrying the extension leaf. By reference to the drawing it will be noted that the vertical rib on the fixture forms an abutment or sto against which the pin strikes in the limited outward movement of the runner and that the bill of the hook being spaced from said rib leaves an entrance slot for the passage of the pin into engagement with the hook Where it is held to prevent horizontal movement of the leaf. The fixtures are attached to the inner side of the end railsll by means of screws 27 so that the supporting member of said fixture will be on a line at one side of the slot 17 for engagement of the pin on the runner with said hook.

The leaves in housed position are supported beneath the projecting opposite ends of the table top in the spaces beyond the ends of the crosspiece 14a onthe upper ends of the sides and end rails of the supporting frame of the table, the bars or runners connected to the aforesaid leaves extending through the slots 17 and 18 in the end and center rails, and in the operation of extending the leaves to increase the size of the top of the table each leaf is moved horizontally outward until the pin 20 engages the rib 23 of the metal fixture 21 at which time the said leaf is beyond and slighty below the outer end of the top so that it may be moved upward and rearward for engagement of the pin with the supporting mem er or hook 24, it being noted that the fixture not only limits the outward movement of the leaf and runner but also serves as a guide in bringing the leaf on a horizontal plane with the main top of the table, and that in this position it is supported andheld by the pin resting in the seat 26 of the hook or supporting member and engagement of the runner with the outer end of the crosspiece 14a, as shown in Fig. 2 of the drawing. In housing the extension leaf the operation described is reversed, that is to say the leaf is .moved slightly upward to disengage pin 20 from the hook member 24 of the fixture and after being lowered to the position shown in Fig. 3 the said leaf is slid inwardly into the space provided therefor below the projecting ends of the main top, it being noted that the depression 19 at the lower edge of the runner provides the lowering movement of the leaf and runner so that the pin will be below the hook member of the fixture and that said leaf is guided by the runner sliding in the lower ends of the slots 17 and 18 in the cross rails of the supporting frame of the table to the upper edges of the side and end rails over which it slides to housed position.

The fixture cooperates with the pin to provide a simple and effective means for guiding the runners in raising and lowering the extension leaf as well as to support and hold the leaf on a horizontal plane with the main top, and although in the preferred embodiment of my invention the supporting member is in the form of a hook having the bill portion thereof turned inwardly or toward the end rail it is obvious that the form may be modified to serve the same purpose, that is to limit the outward movement of the leaf and its supporting runner by the pin striking thereagainst andprovide a support for said pin to rest upon, and consequently I do not wish to be understood as limiting my invention to the special form of supporting member herein particularly shown and described but reserve the right to modifications thereof within the spirit and scope of the appended claims.

I claim:
