EXTENSION-TABLE.

Specification of Letters Patent.

Application tiled May 20, 1909.

Patented Mar. 18,1913.

Serial No. 497,261.

To ou fr0/wm t may concern.'

Be it known that I, JULIUs Moi-1R, of Milwaukee, IVisconsin, have invented an Extension-Table, of which the following is a specification.

rIlhis invention relates to tables of the folding or extensible type, wherein a table is made longer or shorter according to the wishes of the user as the demand for same may arise, the table being made up of two main members which may be pushed togetherclosely or separated to a greater or less extent, the space between them when so extended being taken up by one or more removable leaves.

The object of the invention is to provide an improved arrangementand const-ruction over that already patented by me in conjunction with Charles Mosch on December 1, 1908, Patent No. 905,342, so as, first, to provide a greater range of adjustability; secondly, to simplify and strengthen certain details of construction; thirdly, to enable the table to be easily dismounted and set up; and fourthly, to lock the table automatically in whatever position it may be set.

The aforesaid patent comprises, combined with the two body-members which are united in a sliding manner, a central frame or basket and a set of three folding-leaves which are disposed in said basket belowV the table-top when not in use, and when desired can be raised and used in two positions of extension, two of said extension-leaves acting together and being half the width of the otherleaf, so that in effect the arrangement gives but two extended positions of the table. In my present invention I provide the same number of leaves as before, but these leaves are all of the same width, and means are arranged whereby one, two, or all of the leaves may be used, thus providing three positions of extension; and this number may be multiplied if desired.

Another feature of my invention consists in tlie means whereby the folding-leaves,v

when they are automatically raised and rotated by the spring, are caught and held as they swing around into position, and thus inconvenient rebounding is avoided. This is effected by means of a spring-clip which catches upon a stop-pin on the under side of the bottom-leaf.

An important feature of the invention consists in an improved lockrod which is adapted to automatically catch and hold the table rigidly in each position of extension, so that the table may be moved around by grasping one end thereof without danger of its opening out, which is a common defect of extension-tables. This lock-rod device is a very cheap and simple affair, which, while it adds but a trifling sum to the cost of the table, infallibly accomplishes its purpose.

Ano-ther important feature of my invention consists in the triple-jointed hinge which, in conjunction with the doublejointed hinge described by me in my aforesaid patent, enables me to use the three leaves in the three several positions above referred to. The nature of this hinge will appear hereinafter.

Other features of my invention consist in the details of co-nstruction and the various combinations which will be hereinafter more specifically described and pointed out in the claims.

For the better understanding of my invention I have shown in the accompanying drawings a rectangular table built with my improvements; and herein Figure l is a plan view of the table in its closed or shortest p0- sition, a partof the left-hand top-board being broken away; Fig. 2 is a longitudinal section of the table on the plane 2, the legs being broken away and the extension-leaves shown in elevation; Fig. 3 is a transverse central section on the plane 3; Fig. t is a plan view of the table in its first position of extension (one extensiondeaf being used), a part of the extension-leaf and left-hand top-board being broken away; Fig. 5 is a longitudinal section through the table in the same position, on the stepped plane 5; Fig. 6 is a transverse, central section through the same on the plane 6, the leaves being shown in elevation; Fig. 7 is a plan view of the table in its second position of extension (two extension-leaves being used) a part of each extension-leaf and of the left-hand topboard being broken away; Fig. 8 is a longitudinal section of the table in the same position, on the step-pcd plane 8; Fig. 9 is a transverse central section of the table in the same position, taken on the plane 9; Fig. 10 is a plan-view of the table in the fully extended position (all three leaves being used), a part of the middle and left-hand extension-leaves and the left-hand top-board being broken away; Fig. l1 is a longitudi slides; Fig. 17 is a perspective view of the socket or locking-block for the lock-rod; Figs. 1S, 19 and 20 are respectively a front view, a Vertical axial section and a horizontal axial section ot the same; Fig. 21 is a perspective view of the central frame or basket for the extension-leaves; Fig. 22 is a perspective. view of one of the sliding-rests t'or the leaves; Fig. 23 is a perspective view of one of the extension-slides; Fig. 24 is a perspective view of the sliding swivel-post; Fig. 25 is a similar view partly broken away through the center-leg of theI table; Fig. 26 is a similar View of the same from the opposite side, showing the swivelpost in position therein; Fig. 27 is a perspective View partly7 cut away of the swivelplate for t-he center-leaf; Fig. 28 is an end or face-view of the lock-rod and operatinghandle therefor; Fig. 29 is a longitudinal view of the lock-rod, operating-handle, bearing-block and locking-block, parts of the rod being broken away; Fig. 80 is a lonigtudinal section through the bearing-block of the same; Fig. 31 is an inside end-view of the bearing-block and handle, showing the lockrod in section; Fig. 32 is a plan View of the spring-clip for holding the leaves after they have swung around showing the stop-pin in section; Fig. 33 is a perspective view of the stop-piece for the slide-rests; Figs. 34', 35, 36 and 37 are longitudinal sections through the triple-jointed hinge in its successive positions from the completely closed to the completely extended position of the table; Fig. 3S is a view similar to Fig. 3G but on a larger scale; Fig. 39 is a bottom-plan section through the hinge on the plane 39 of Fig. 38; Fig. 40 is a sectional elevation of the double-jointed hinge; Fig. 41 is a fragmentary transverse section ot' the table on the plane 41 (Fig. l) Fig. 42 is a perspective view of the endl of one of the corner table-legs, showing the manner of removably attaching it to the table; Fig. 43 is an inside elevation of the end-board ot t-he table as provided with an internal operating-handle for the lockrod; and Fig. 44 is a side elevation of the same arrangement, the end-board being shown in section in the plane of the axis of the lockrod.

In these drawings the same part is designated. by the same reference letter or numeral in each figure.

Because I have herein shown a rectangular table it does not follow that the improvements, or many of them, cannot be used upon other shapes of tables; nor that beause I have shown three extension-leaves, a greater or less number cannot be used consistently with my invention.

The table comprises two extensible or endmembers A which are connected together in slidable .relation with a rectangular centertrame B by means of a plurality of extension-slides C. Upon the center-trame B are articulated, in a manner which will be hereinafter described, the central-extension-leat D, and two lateral extension-leaves Fi and E.

Each of the members A comprises a topboard a, a pair ot' legs a2 which may or may not be provided with c: sters of", side-boards d* and end-boards ((5,: and the legs ai are removably secured to a cross-plank a by the novel means shown in detail in Fig. 42. A headless lag-screw (LT is screwed longitudinally into the end of the leg and its end is threaded to receive a nut at and washer a, said nut being inserted through a suitably placed hole in the plank a and the nut at being thereafter screwed do-wn over the plank as shown, thus enabling the legs' to be rcmoved and set up without ditlicnlty and without disturbing the operation ot the table.

The extension slides C are disposed in symmetrical. sets on each side of the center as in the patent hereinbetore referred to, the outermost. slide ot each set being secured in a suitable manner to the end-member ot the table. The preferred manner of securing it thereto is by means of screws c passed through tubular bores cf extending upward from the bottom of the slide, said screws entering and securing the slide to the top-board a of the end-piece. The cross-pieces a. to which the legs are secured are in turn fastened by screws al" to the outer or fixed slides as shown, the spacing-pieces a. being inserted between them so as to hold the cross-pieces apart from the slides and center-trame B. The side-pieces a" are independently secured to the top-boards a. by screws (12 set diagonally through recesses u.

I have succeeded in considerably simplifying the ar 'angement of the slides C as shown in the patent above referred to, for instead ot' the T-shaped tenons and mortises termed on the slides, I arrange a. dovetailed groove c3 on each side of each slide and a plurality of double dovetailed tenen-strips ci, one halt of each of which tits in one ot two opposing grooves (see Figs. 23 and 41). The sides of the center-frame B are grooved in like manner to receive the tenon-strips c, and the transverse end-ba rs of the trame are cut out if'necessary as shown at 7) in Fig. 21 to avoid interference with the nuts a".

The central extension-leaf D is rotatably lll).

mounted. upon the upper end of a swivelpost F which has a flattened conical head j engaged by a cupped swivel-plate G secured to the under side of the leaf, substantially of the form shown in the patent above referred to. Said swivel-post is socketed in a bore it in the upper end of the center-leg H, and it will be observed that I have considerably simplified the construction by making the swivel-post entirely of metal. Said post is held from turning by means of a screw f2 driven into the side of the center-leg and the end of which projects into a groove f3, the end of said groove also acting as a stop to limit the rise of the leaves and being provided with a rubber cushion f4. A pivoted nger-pawl I pivoted. upon a pin z" has a tongue which extends into one of four notches 2 corresponding to the four optional changes in size of the table. A light plate-spring 3 holds the nose of the pawl pressed into engagement with said notches, and a press-button 4 permits its withdrawal therefrom by the finger. The cross-plank Z22, which forms the means for uniting the center-leg H to the frame B, is made in composite form, with a central recess 0" adapted to receive the coiled compression and torsion-spring J and cylindrical guide-block 54,' said spring having one end secured to the plank b5 on which it rests and the other end to the swivel-plate, exactly as described in my aforesaid pat-ent. The leg H is removably secured to the cross-piece b5, which is the central component member of the plank b2, by means of a pair of anglepieces h2 mounted on the sides of the leg and secured to the plank by bolts 7L having wing-nuts 724.

The spring J being under compression, the release thereof by pressing the button t after the two halves of the table have been separated causes the leaves to be raised to the limit of their movement, which is so placed that the leaves clear the top-boards, as shown by the dotted-line positions of Figs. 5 and 6, and the spring J, being also under torsion, will act after raising the leaves to swing them around upon the aXis of the swivel-post I. In order to limit the turning-movement to a right-angle, a depending vertical pin K is mounted on the under side of the leaf D, in position to enter a hole 7c in a cross-board o of the frame B when the leaves are depressed, a block 7a2 being set against one side of this hole to prevent any turning-movement beyond that position or in that direction. In the middle of the adjacent side of the frame B, and on the inner side thereof, is mounted a springclip L, the same consisting of a resilient plate having a socket Z adapted t0 receive grasp and hold the pin K when the latter, carried by the insertion-leaves, is swung around into position of use. This springclip L therefore prevents any rebound on the part of the leaves and prevents them from occupying any but the correct position for insertion in the table.

The means by which the leavesE", E2, fold one over the other, and are articulated to the leaf D so as to permit of this action and to permit not only of the member E occupying when unfolded a position on a level with the leaf D, but also to permit of the upper leaf E2 occupying when unfolded position either on a level with the folded leaf E', or with the center-leaf D, fo-rms a special feature of my invention which is shown on Sheet 7 of the drawing (Figs. 34 to 40 inclusive). The leaf E is hinged to the leaf D by the double-jointed hinge M, the same as shown in my aforesaid patent, being composed of a deep casing or pocket m mounted in the edge of the leaf D in a recess therein, a joint-base m2 mounted on the edge of the leaf E', a slidingmember m3 mounted within the pocket m, and the hinge-leaf mt which is pivotally connected by the pintles m5, m to the jointbase m2 and sliding-member m3 respectively. In the case of the leaf E2 however, three positions are required instead of two, and to this end I have devised my triple-jointed hinge N, the construction of which is as follows. A deep-casing or pocket a is mounted in a recess in the edge of the leaf E2, and a joint-base n2 is mounted on the edge of the leaf D, and a sliding-member n3 is slidably mounted within the pocket n; these three members being substantially the same as the members m, m2 and m3 respectively of the double-jointed hinge M, eX- cept that the pocket 12, is deeper. The sliding-member as is connected with the base fn? by means of two members at, a, which I will here term links and which are pivotally united by the pintles a6, a7 and as. The construction is such as to allow each of the three successive positions of the hinge shown in Figs. 34, 35 and 37; in the first of which the two hinge-links are both drawn out; in the second the first hinge-link n* is pushed into the pocket a; and in the third both hinge-links are in said pocket. The position shown in Fig. 3G shows the act of bringing the leaf into the third position and before the hinge-links n4, a5 have been pushed into the pocket, and to prevent them from dropping down in this position and hold' them rigidly extended, a small tab n is turned down from the metal between v two pintle-lugs on the link a5, said tab resting against the joint-base n2 and being received in a recess n10 upon the edge of the pocket n when the leaves are pushed together. It will be observed that, to avoid unnecessary notching on the edge of the leaf E, to make room for the hinge, said leaf is made slightly narrower than the leaf the surface 03.

E2 as shown in Fig. 34, being cut away slightly only on one side of the edge as shown at e, so that only when this leaf E is unfolded, that is to say in the fully eX- tended position of the table, does the notching appear upon the surface of the table.

In order to support the leaves in the several positions I arrange a set of stepped sliding-rests O which have dove-tailed tenons o engaged in dove-tailed grooves 02 in the edges of the side-members of the frame B; said rests having two rest-surfaces 03 and o4, the rst being the thickness of a leaf above the side-edges of the frame B and the second the thickness of a leaf above A notch 05 is conveniently provided whereby the rests may be drawn to-gether, and a metal-clip 0G is mounted at the corner of the frame B on the inner side of the rest, which clip has a tongue 0T en` gaging in a groove o8, and a pin o9 is set in said groove which limits the outward movement thereof. This is an important and simplified construction over that shown in the aforesaid patent, because it enables the rest to be shaped as continuous molding and requires' no special cutting other than the step 03.

In the iirst posit-ion of extension, iii which only the leaf E2 is used, the slides O are naturally pulled apart, as shown in Figs. 4, 5 and 6, so that the three leaves rest directly upon the edges of the frame B. In the second position of extension, in which the leaf E2 is open and rests on a level with the leaf E as in Figs. 7, S, 9, and 35, the rests O are drawn in part way until the leaves I), E rest upon the rest-surfaces 03, while the unfolded leaf E2 rests upon the rest-surfaces 04, and the slides C. I'Vhen the table is fully extended, the slide-rests are drawn in until the center-leaf D rests upon the rest-surfaces o4 and the other leaves upon the slides C, as shown in Figs. 10, 11, 12 and 37. Suitable dowels will ordinarily be placed upon the edges of the leaves as shown in my aforesaid patent, but are not here shown as they form no essential part of my invention.

For the purpose of locking the table in any of the positions in which it may be placed so as to prevent it from opening out when pulled from one end, a simple and effective locking-device is very much to be desired. For this purpose I introduce at each end of the table a lockrod P, which is pivoted in a bearing-box p set in a hole bored in the end-board t5 of the table. The lockrod has on one end an operating-handle or arm p2, and the opposite end of the bearing-piece p is recessed at p3 to receive the projecting-end of a pin 294 set in the lockrod, whereby the lockrod is prevented from endwise movement and the rotation thereof is also limited by the shoulders p5 at the ends receive the end of the rod P.

of recess 723. It is not essential to my invention that the handle p2 should be placed on the outside of the end-board, and if desired the handle p2 and pin pt may be interehanged in position. The handle is secured against turning upon the rod in any suitable manner, as by a set-screw p The free end of the rod P passes through a locking-block Q, which is set in a hole in the end-board of the frame B, as shown in Figs. 10, 11, 1Q, 13, 14, 21 and 29; said locking-block (see Figs. 17 to 20) has screwears g or other means of attachment to the frame B, and a bore Q2 fitting the rod and acting as a journal-bearing therefor; and on opposite sides are a pair of notches or recesses Q3 adapted to pass any one of a number of pins p7 which are set upon the rod P is positions corresponding to the several extensions of the table. To prevent the rod from being drawn completely out, a washer ps may be mounted on the end of the rod, and the edges of the cross-plank b may be beveled off, as at b?, to avoid the catching of this washer on the edges thereof. On the inner face of the block, and on each side of the recesses q are formed oblique cam-faces g4 (see Figs. 17, 1S and 19) which are engaged by any of the pins p7 after it has passed through the recesses g3 and is then rotated, so that by proper placing of the pin p7, the rotation of the rod tends to draw the table up tightly into position and to compensate for any irregularity in the width of the leaves o1` the setting of the pins upon the rod. It will be observed, as shown in Figs. 19 and Q0, that the recesses g3 are narrowed to the size of the protruding ends of the pin 777 at the cam-face of the block Q, and that inside the bore they open out obliquely, forming cam-faces Q5, so that when in the pushing together of the table one of the pins p7 enters the bore of the bleek its ends will be engaged laterally by the cam-faces g and turned into the position in which it passes completely through the notches, when it will drop over the cam-faces y* by reason of the weight of the handle 2J. Thus there is no resistance encountered to the pushing together of the table, and when pushed up to the locking position it will lock automatically.

In handsome or ornamental tables it will often be preferable to place the operatinghandle of the lockrod out of sight, and for this purpose I may adopt the alternative arrangement shown in Figs. 43 and 44. On the inner face of the end-board t5 of the table a recess am is cut (this would be unnecessary in eases where a space is left between the frame B and the end-board in the closed position of the table, see Fig. 14) and the bearing-block R set therein to An operating-handle r is fixed upon the rod adjacent to the bearing-block and within the recess a, as by means of a pin r2, said handle having a limited angle of movement sufficient to release the pins p7 from the locking-block Q when the handle is moved into the dotted line position, and the weight of the handle otherwise holding the pin p7 in engagement with the cam-faces qt of the locking-block. Means are provided for preventing endwise movement of the rod in the bearing-block and also limiting its angular movement, as for example a notch r3 on the inner end of the block which is engaged by a pin r4.

For the purpose of limiting` the extension of the slides I provide improved means consisting of a series of stepped plates S S mounted on the bottom-edges of the slides and interlocking with each other in the closed position as shown in Fig. 14e. Each plate (except those on the outermost slide and the frame B) has an end projecting over the adjacent slide, and projecting-pins S2 are set near the inner ends of the slides to limit the extension, said pins striking upon the stop-plates when the table is fully drawn out.

Having thus described my invention, what I claim as new and desire to secure by Let-ters Patent is:
