Patented Nov. 10, 1931 UNITED STATES PATENT OFFICE EVEETT J. HEULE AND PAUL NOVAK, OF SUPERIOR, WISCONSIN, ASSIGNORS TO WEBSTER MANUFACTURING COMPANY, OF SUPERIOR, WISCONSIN, A CORPORATION OF WISCONSIN EXTENSION TABLE Application led May 15, 1930. Serial No. 452,639.

Our invention relates to extension tables and has for its object the provision of an improved table of such type, and in which exy ltension leaves are mounted on slide bars and 9 positioned, are beneath a main table top, when in closed position, and may be drawn outwardly and raised into operative position flush with a stationary top of said table, thereby extending said table by adding a leaf to one or both of its ends. 71th this, and

other objects in view, it consists of the structures, combinations and arrangements of parts hereinafter described and claimed.

In the drawings, Fig. 1, is a top plan view of said invention showing one of the extension leaves 'thereof drawn out to an intermediate position between closed and operative positions, as shown in section in Fig. 2; also showing diagrammatically, in broken lines, the approximate positions of the hereinafter described table legs, side and end rails, spacing and top-supporting blocks, cheek blocks, and sliding leaf arms. Fig. 2, is a vertical longitudinal section of one end of said table on the line A-B of Fig. 1, showing one of the table legs partly broken off and showing one of said extension leaves in an intermediate position. Fig. 3, is a similar section showing said extension leaf in operative position. Fig. 4, is a similar section showing said extension leaf in closed position. Fig. 5, is a fragmentary end elevation of said table, showing said leaf in closed position, Vand Fig. 6 is a fragmentary vertical transverse section on the line C-D of Fig. 1.

In the drawings, 1 is a stationary table top, supported on spacing blocks 2, 3. which are mounted on side rails 4, 5 which are supported by legs of any suitable numberv or lo structure, as 6, 7, 8 and 9. End rails 10 and 11 are also supported by said legs. Said stationary top is supported by said spacing blocks above the tops of said legs and rails so as to provide a space between said top and rails and the tops of said posts for the passage below said stationary top of extension leaves 12 and 13 at opposite ends of the table respectively.

Secured to, and depending from each of said leaves are one or more longitudinally directed sliding guidearms, as 14, 15, 16, 17, adapted to overlap one or the other of two longitudinally directed stationary cheek blocks as 18, 19, which are secured to, and depend from said stationary top.

Since the structure is similar at each end of said table, it is believed sufficient if only one end be further described in detail.

Extending transversely from each of said1 cheek blocks is a stationary guide finger or pin, as 20, adapted to engage a three-step groove formed in the opposing side face of a vcorresponding one of said arms at one end of said table.

The groove in each of said arms comprises a lower, and intermediate and upper plane portion, said lower plane portion being near the inward end of the arm, as at 14a, the upper portion of vsaid Vgroove being near the out-,KN ward end of said arm as at and the intermediate portion of said groove extending between the ends of'said upper and: lower p0rtions as at 14?), Said lower and upper portions of said groove are connected with said intermediate portion by outwardly and up'f 'i Wardly inclined portions, as at 14d and 14e, respectively, and the outer end of said intermediate portion -extends outwardly beyond the lower end of said inclined portion 146, to form a pocket, 14;, for the guide and sup-v` porting finger 22 when said leaf is in operative position. The outer ends of said arms are supported by said end rails and extend through slots formed therein.v

Supported by any suitable means on said end rails as by a block 21, is a finger 22 adapted to extend into said groove.

i If desired, the extension leaf and arms mayU be omitted at one end of the table.

-To move one of said lleaves to operative position, assumingl it to be in closed position beneath the stationary top with the finger 20 extending into the intermediate level of the groove in the opposing guide arm, and'l the finger 22 extending into the upper level 140 of said groove, the operator draws said leaf outward, causing the guide arms upon which it is mounted to ride onsaid lingers in such manner 'that the inclined portion 14d and part of the lower portion 14a of the groove will pass said finger 20 thereby lifting the inward end of said arm. At the same time the inclined portion 111e of said groove will pass said finger 22 and the inte-rmediate portion 14?) of said groove will engage said pin 22 thus raising the outward end and means for supporting the fourth said linger, said leaf being also attached to the outer end of the second said arm.

In testimony whereof, we hereunto aliix our signatures.

of said arm so that the leaf is flush with the Y y,

stationary top of the table. The leaf is then pushed toward the stationary top until it con-1 tacts or approximately contacts therewith at the same level. lVhile pushing the leaf into operative position, the operator manually' supports the saine to prevent the inclined groove 14e from again engaging said pin Q2', which thereupon Abecomes engaged' by the pocket end lef of said groove and supports the outer end of said arm and leaf in operative position after the operator has withdrawn his manual support thereof. By reversing the procedure, the leaf is returned to closed position.

1. In a table, the combination of legs, side rails supported by said legs, spacing blocks mounted on said side rails, a stationary top mounted on said blocks and spaced thereby above the tops of said legs and rails, a cheek block depending from said top between said spacing bloclrs, a reciprocable guide arm e2;- tendiug longitudinally of said' table below the plane of said top and adaptedV to overlap said Y cheek block, said arm having a three-step groove formed in its side facing said cheek block and extending longitudinally of said arm, the lowest portion of said groove being near the inward end of said arm and being connected with the intermediate portion of said groove by a riser portion, the highest portion of said groove being near the outward end of said arm, said intermediate portion of said groove being connected with said highest portion by ariser portion, said intermediate portion having a pocket portion extending outwardlv beyond the lower end of the upper said riser portion, a transversely directed finger extending from said cheek block into the inward half of said groove, a transversely directed finger extending into the outward half of said groove, means for supporting the second said finger, and a table leaf mounted upon and secured to the outer end of said arm.

2. The combination with the structure described in claim 1, of a second cheek block depending from said table top and extending parallel with the Hirst said cheek block, a

second guide arm adapted to overlap said second cheek block, said second guide arm being grooved in similar manner to the first said guide arm, a transversely directed linger l extending from said second cheek block into the inward half of the groove 1n the second said arm, a transversely directed finger extending'into the outward half of said groove,
