L. L. RICHARD.

AUXILIARY TABLE,

APPLICATION FILED MAR. 1. 192|.

Patented Apr. U., 1922.

ATTORNEYS narran estaras LEROY L. RICH-ARB, 0F VSALA, CALIFORNIA.

AXIIIARY TABLE.

raras/ae.

Application filed March 7', 1921.

To all whom t may concer/n y Be it known that I, LEROY L. RICHARD, a citizen of the United States, residing at Visalia, in the county of Tulare and State of California, have invented certain new and useful Improvements in Auxiliary Tables, of which the following is a specification.

My invention relates to that class of table-attachments comprising a supplementary or auxiliary table, relatively small, and adapted to normally lie, when not in use, close up under the main table, and, when required for use to be readily extended therefrom to a lower level, thereby providing for the convenience ofv children, particularly in refreshment parlors.

The object of my invention is to provide an auxiliary table of this type, simple in construction, cheap to manufacture and of good appearance and which is held, both in its folded and extended positions, with stability and rigidity sufc'ient for its purpose, without detracting from its ease of operation in throwing it into and out of use.

To this end my invention consists in the novel auxiliary table` which I shall hereinafter fully describe, by reference to the accompanying drawings, in which- Fig. 1 is a side elevation of my auxiliary table, in its extended position, ready for use, the dotted lines showing its folded position out of use.

Fig. 2 is `a part elevation and' part section on the line 2 2 of Fig. 1.

Fig; 3 is a part plan and part section on the line 3 3 of Fig. 1,. K

1 indicates the slab or top of the main table and 2 is the shelf constituting the auxiliary table. The auxiliary table may be' of any predetermined size and shape', as', for example, as here indicated, a relatively small circular shelf adapted, in its more common use, to hold a refreshment dish or glass; and for this purpose, I havey shown it as'y provided with nxed peripheral confining lugsy 3, and an adjustable' lug et, playing in a slot 5 of the shelf, andprovided with a shank slidably mounted in guides 7 under the shelf, said shank having an underlying linger-hold 8', and a controlling springl 9; p p Y,

By grasping the finger holfd 8, the adjustable lug 4 may readily'beA moved outwardly to receive the refreshment vessel" and when released said lug will move in again, under the tension of the spring, to properly hold said vessel against the Xed lugs 3;

Specification of Letters Patent.

Serial No. 450,292.

At one side or portion of its rim, the auxiliary table shelf 2 is provided or formed with an angularly rising bracket 10.

11 is a supporting member which has an angularly depressed bracket 12, which when said member is secured under the main table l, as shown in Fig. 1, lies substantially parallel with the bracket 10 of the' auxiliary table-shelf. The supporting hanger for the auxiliary table-shelf comprises a pair of associated links 13 and 14. The link 13 is pivoted above to the bracket 12, at 13 and below, it is pivoted to the bracket 10, at 13 The link 14 is similarly pivoted to said brackets at 1-1 and 14, these connections thus being of the parallel-rule@ type, enabling the table-shelf 2 to maintain its horizontality in all positions. The links 13 and 1 4 may assume any shape in cross-section, flat, angular or curved, but in their best form, they are approximately semi-circular with straight edge portions, as seen in Fig. 3, and are associated in interfitting overlapping relation, thereby complementing each other to form a substantially cylindrical column giving strength and rigidity, and having a good appearance. Moreover, this form and association of the links gives opportunity to make their inter-tit somewhat close frictionally but without interfering with their relative sliding movement,

thereby adding to the general rigidity of thecolumn, in all its movements and positions, and tending to render more certain the locking together of'said links against relative movement, in order to hold the table shelf in any of its predetermined positions, as, for example, at the extremes of movement.

The locking is automatic and also isreleasable by pressure applied to the auxiliary table-shelf in moving it to and from its positions. Any suitable pressure-yielding latch may vbe used to releasably lock' and hold the two links against relative movement. In the form of links here shown, the latch prefer comprises a pair of beveled or round ended pins 15 slidably mounted in the lapped portions' of the link 13, andl yieldingly controlled by a spring 16 within said link, said pins being adapted to engage sockets or holes 17 and 18 in the lapped portions of the link 14, theV sockets or holes 17 defining the relative movement of the links when the auxiliary table-shelf is extended for use, as shown by the full lines in Fig. 1, and the 4 y sockets @11019518 defining the limit of move# ment when the auxiliary table-shelf is folded up under the main table, as shown by the dotted lines in Fig. 1.

ln the face of the link 14. is a hole 19 to receive the adjustable lug 4 of the auxiliary table-shelfv when the device is folded up, thereby enabling the parts to lie close together.

lt will now be seen that if, when the device is in the folded position shown by the dotted lines in F ig. 1; a downward pressure be imposed upon said table--shelf 2 tending to swing the links, the latter by relative movement in-opposite directions will break the yielding latch connection at 18 between them; and this movement will continue until as the table reaches its limit of extension as shown by the full lines in Fig. 1,7the spring latch pins 15 will enter the sockets 17 and thus lock the links again. Conversely, an upward pressure on the auxiliary table, will reverse the relative link movement, unlocking them at the beginning and relooking them at'the end of the folding movement,

I have herein described my device in its preferred form and use; but it is to be understood that its use may be varied to serve the purposes of any folding table-shelf, and itsY structure may be altered in details of formand shape without departing from the invention as defined by the appended claims,

I claim 4 1. The combination of a shelf; a supporting member a pair of links pivotally connecting said shelf and member in parallel relation; and means carried and actuated by said links for locking them together against relative movement.

2. The combination of a shelf; a supporting member; a pair of links pivotally conrelation, said links interfitting in comple-v mentary overlapping slidable relation; and a' pressure-yielding-latch carried by said links for locking them together against relative movement. Y

.Y 5. The combination of a shelf; a supporting member; a pair of linkspivotally connecting said -shelf and member in parallel relation, said links intertting in complementary overlapping slidable relation.; and
