EXTENSION-TABLE.

Specification of Letters Patent.

Patented March 24, 1908.

:Application filed. July 25, 1907. Serial No. 385,510.

To all whom it may concern:

Be it known that PETER FRANCIS, deceased, late a citizen of the United States, and a resident of Marine City, in the county of St. Clair and State of Michigan, did invent certain new and useful Improvements in Extension-Tables, of which the following is a specification.

This invention is an extension table, and more particularly that kind having extension slides at its ends on which the extension leaves are supported, the parts being so constructed and arranged that the leaves can be stored under the stationary top of the table when not in use.

The object of the invention is to simplify the construction and arrangement of the eX- tension slides and leaf-supporting means in order that the leaves may be readily placed in position for use or stored away, and also to make said parts readily accessible for the purpose of repair without disturbing or injuring the other parts of the table.

In the accompanying drawings Figure 1 is a bottom plan view showing the extension leaves in position at the ends of the table. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a bottom plan view showing the extension leaves stored under the stationary top of the table. Fig. 4 is a longitudinal section on the line 4 4 of Fig. 3. Fig. 5 is a cross section on the line 5-5 of Fig. 1. Figs. 6 and 7 are sectional details showing modified forms of leaf-supporting means.

In the drawings 10 denotes the side rails of the table to which the stationary top 11 is secured in any suitable manner. The side rails depend from ythe top andare con- ,nected at their ends by cross bars 12 and` 13,

respectively, and at the middle by a cross bar 14. The legs 15 of the table are secured to the bottom of the cross bars 12 and 13. Under the stationary top, above the bar 14 is a cross bar 16. The side rails 10 space the cross bars 12, 13 and 14 sufficiently from the top 11 so that the extension slides to be hereinafter described may enter freely therebetween. A suitable distance inwardly from the side rails are located guide rails 17 which are secured to the top of the cross bars 12,13 and 14, and the cross bar 16 is secured to the top of the guide rails.

At each end of the table is an extension slide comprising longitudinal bars 18 connected at their outer ends by end rails 19. The longitudinal bars of one of the slides are connected at their inner ends by a cross bar 20, and this slide is mounted on top of the cross bars 12, 13 and 14 inside the guide rails 17. On the cross bar 14 is pivoted a turn button 21 which, when extended` into the path of the cross bar 20 acts as a stop to prevent withdrawal of the slide. Upon swinging the button down so that it will be cleared by the cross bar, the slide can be removed from the table. The other slide is mounted on top of the cross bars 12, 13 and 14 on the outside of the guide rails 17, and this slide is prevented from being entirely withdrawn from the table by turn buttons 22 pivoted on the inner ends to its longitue dinal bars 18, said turn buttons being engageable with pins 23 mounted between the cross bars 14 and 16. Upon swinging the buttons d own so as to clear the ins, the slide may be removed from the tab e. The length of slides is such that their end rails 19 will meet the side rails 1() when the table is in contracted position.

Each extension slide carries an extension leaf 24 which is loosely supported thereon so that it can be elevated sufficiently to bring it flush with the stationary top 11 when the slide is pulled out from the table. There is sufficient space between the longitudinal bars 18 of the slides and the top 11 to permit the leaves to enter therebetween when the slide is pushed back under the table. To the bottom of the leaves are secured longitudinal strips 25 to which are secured inclined plates 26 having a shoulder 27. To the sides of the bars 18 are secured inclined plates or cams 28 which co erate with the plates 26 for the purpose ofp elevating the leaves into position so that they will be ilush with the stationary top 11. To bring the leaves in this position, the slides are iirst pulled outwardly until the leaves are suflciently beyond the ends of the stationary top. The leaves are then pulled outwardly, and when the plates 26 stri re the inclines 28, they ride up the same until the shoulders 27 are engaged by the top of the inclines. This elevates the leaves and brings them flush with the stationary top, the shoulders 27 being so located that they are engaged by the inclines 28 when the leaves are in this position.

For the purpose of holding the vleaves in extended position, to their front ends are sel the end rails 19.

cured catches 29 which enter recesses 30 in Similar catches 31 at the rear ends of the leaves are engageable with keepers 32 on the bottom of the stationary top 11. When the table is contracted, the keepers 32 enter the recesses 30 as shown in Fig. 2. To the cross bars 12 and 13 are pivoted levers 33 having at one end a hook 34 which is engageable with an eye on the end rails 19 for the purpose of holding the slide in extended position. The levers are slotted as indicated at 36 to receive their pivots, in order that they may be swung over on the cross bars 12 and 13 when the table is in contracted position as shown in Fig. 1. On the bars 18 are laterally projecting pins 37 which are engageable by the rear ends of the longitudinal strips 25 which limits the rearward movement of the leaves on the slides and also carries them forwardly with the slide when the latter is pulled out from under the table.

To store the leaves under the table as shown in Fig. 1 the slides are pulled outwardly slightly so that the catches 29 and 31 can be disengaged, after which the leaves are pushed inwardly which disengages the shoulders 27 from the inclines 28 and lowers the leaves so that they may pass under the stationary top of the table when the slides are pushed inwardly thereunder. The side rails 10 are grooved as indicated at 33 to receive the side edges of the leaves.

In the modification shown in Fig. 6, rollers 39 are substituted for the inclines 38. In the modiiication shown in Fig. 7 the eXtension leaves are connected to the longitudinal bars 18 of the slides by parallel links 40. The parts operate in the same manner as those heretofore described.

By the construction herein described the extension slides and leaves can be readily placed in position, and all the parts are accessible and removable for the purpose of repair or otherwise, without disturbing or injuring the stationary portion of the table.

Whatl is claimed, is:

An extension-table comprising ay stationary top, side-rails depending therefrom, end and intermediate cross-bars connecting the side-rails, a catch on the intermediate crossbar, longitudinal guide-rails between the top and the cross-bars, extension slides coinprising longitudinal bars having end rails at their outer ends, the longitudinal bars of one of the slides working on the inner sides of the guidebars and connected at their inner ends by a cross-bar which is engageable with the aforesaid catch to limit the outward movement of the slide, and the longitudinal bars of the other slide working on the outer sides of the guide-bars and having catches, and pins on the aforesaid intermediate cross-bar engageable with said catches to limit the outward movement of the last mentioned slide.

In testimony whereof 1 afIiX my signature in presence of two witnesses.
