T0 all 'whom 'it may concern: y v

Be it known that I, ISAAC CooKLIN, a sub'- ject of the King of England, and residing at Liverpool, in the county of Lancaster, England, have invented Improvements in Dining Tables ('for'which I have filed an appli# cation in England, January 28, 1915, Patent No. 1374), of which the following is a speciication. I

vThis invention has reference to tables having a removable leaf or leaves by which the table may be extended or shortened at will, as required, andit relates more particularly to such tables wherein, upon the'operation of same by screw or equivalent gear, the leaf or leaves can be introduced in position in the tabletop, and removedfrom same,`and the table shortened by the mere operation ofthe screw or like gear, i. e. without hand manipulations. In a table of the above kind according to this invention, the edges of the leaf or leaves-and the edges of the permanentrtable top portions are provided with dowels or like registering and engaging devices; and when a leaf is to beremoved, the

table is actuatedvsay by its yscrew or equivalent loperating gear, one: end of the table is disengaged from and moved away fromthe leaf, and then, by a further movement by the gear, a part of the table acts on apart on or of the leaf,` and the "other edge of the leaf will be disengaged and freed from the table, and one edge of the leaf will fall down into cut away parts of the tableframes or slides below, the other edgeibeing held up by pivot cam4 blocks'or pieces on one of they slides or frames of the table, 'so that the leaf is tilted; and then by closing thetable yby thev operating gear, the pivot cam"parts which arepreferably on. thev innerframes or slides-are moved away .from the leaf and so allows the then upper edge to fall and theJv wholeleaf take the horizontal position, and its undersurface restson the upper edge of the cut away parts of the slides.A Toinsert a leaf from the stowed position, the opposite action takes place. Y

In thefcase" where thereare twe leaves,

' elevation with the 4two leaves inserted; and

Figures 3, 4c, ando-*show one ofthe 'leaves in different positions when operating the table; whilst AFigures 6 and 7, are,y respectively, a longitudinal sectional elevation` with the leaves inserted, and a cross section, and Figure 8 is a plan of the table showing the top removed.. Fig.` 9; is` a bottom planV view of the table. f'

Figure 10 shows .the dowels and level of. l 4

leaf when disengaged from the tabletop.,`

In the table shown, the two end portions 1 are attached to two outside framesor slides 2 to which the legs?) are fixed, and these side frames 2 project a considerable distancel beyond the meeting edge parts4 of the top 1, as shown; and they are cut away at their upper edges. a portion of which cutaway parts 'extendback in the lforni of a slot 5,

whilst'the other cut away portionextends to nearly the end of the side frames, where an upstanding portion Glis left"and acts `upon one edge of the leaf when operating the( table, as hereinafter described.

` The leaves are designated 7, and they each have at their outer edge a downwardly'projecting horn 8. which comes on the outside of the frames 2; while the frames 2`h'ave on their outsides a projecting stud 9,`which acts on the horns 8 when opening. the table for stowing a leaf, and also inopening the table when bringing a leaf up into position.

' When a leaf is being removed and stowed, the studsf9 pull the dowels lout of the table top portion 10, as hereinafter described, after the dowels 111 have been pulled out of thetop 1 by the rst action of the screw gear.

Both ends of the table so far described are similar.

The central top portion of the table is attached to two inner slides 15, which lie within the slides or frames 2, and have a continuous projecting tongue 16, which fits and slides in corresponding grooves on the inside faces of the outside frames or slides 2 of the table, and these inside frames or slides 15 are -cut away at their upper edge, a part 17 of which (which is similar to the slot 5 c in Figure 2) is in the form of a slot, beyond the end of which the slide extends, the line 18 representing the end of such slide, so that the leading ends of both the stationary slides or frames 2, and the inner intermediate slides or frames 15 overlap one another in all positions. i

The` two inner slides are connected together by cross bars 20, and the end outside frames 2 are also connectedy together by cross bars 21, and 21X, both of which project downwards below the underface of the Central slides. or frames15; and these two sets kof . bars 20, 21 vand 21X operate in connection with one another, in some cases, in

' operatingthe table, as hereafter explained.

With regard to the actuating gear, this consists of a screw 25 such as is commonly used yin tables, mounted and vadapted to be turnedinthe cross frame member 26 meshing and working-ina nut 27 on one end of thetable; but this screw `25 is not geared directly to the other end of the table,\b`ut ris connected with and acts on same indirectly 'through va frame consisting of an end cross slides or frames 15when the table is operated at' certain` times, as the ends of the. cross member 26"*fit and slide in grooves 291 inthe inside of the side slides or frames 15.

On .the inside of the ends of the slides or l frames 15, pivot cam blocks 31 with inclined faces are fixed in connection with which bars 30: fixed on the under side of the leaves work, one. end'of the bars extending beyond the leaf vedge forfpurposes hereinafter dev scribed, whilstthe other ends are inclined and operate in connection with the inclined ends of the pivot cam blocks 31, and the upper edges of the inclined faces of the cam blocks act as fulcra to the bars 30 and leaf, and as for the purposes hereinafter described. s

When a leaf is in position in the table top the bottom edges of the bars 30 are clear of and stand some distance above the upper or pivot face of the pivot cam blocks 31, it being lifted off' same in the closing action, after the leaf has been brought in between the . parts 1 and 10, by the dowels being wedge shaped or inclined, whereby when they enter the dowel recesses, they act on the upper surface of same and so lift the leaf; but when the leaf is free ofthe parts 1 and 10 it is free to and'does drol In removing a leaf, the screw 25 is turned in the backward direction so as to unscrew' the screw, the effect of which is that,

through the nut 27 and frame 26X, 28, the

outer slides 2 and end 1 will be moved away from the outerr edge 0f .the further leaf 7, so as to pull the dowels 14` out ofthe sockets, and these' dowels are removed, and not the others 13, owing to the frictional contact of the upper surfaces of the projecting ends -of the bars 30 on the under surface ,of the table portions 10. In this position the bars 30 and leaf will be held horizontal, the lower edges of the bars being above the level of the upper surface of the pivot cam blocks 31. Then upon thefur ther backward turning and extending movement, the studs 9 come against and engage.

the inside of the horns 8 of the leaf 7, and thereby pull out 'the dowels 13 from the sockets in the central table portion 10. `When vthis stage is reached, the leaf and dowels clear of both top portions 1 and 10, the leaf can then drop down, and the ends ofthe parts of the bars 30 beneath the leaf 7 will fall on tothe top of they pivot cam blocks 31 on the ends of the inside of the intermediate slides 15, and such blocks Ithen serve as pivots or fulcra to the' bars 30 and leaf, and the other end of same drops down to the inclined position shown in Figure 5, so that it, comes on to and rests on the upper face of the cutaway parts or slots in the outside frames 2 and the inside frame 17. In this position the inner and lower edge of the leaf 7 will be below the toppart 10, and will lie near or on the inner faces of the upwardly projecting parts 6 of the side frames 2. Then the screw 2 5 is screwed up, with the result that the side frames 2 are moved inwards, and the barsf`30 slideover the fulcra of the cam blocks 31 (whichthe upper edge of the inclinesbf these blocks form) so that the edge of the further or in ner edge of the leaf 7 keeps against the pro.- jections 6, the leaf moving with the frames 2; and then the back ends of the bars 30, which are inclined as shown, leave this fulcra of thev cam blocks 31, and slide downy the inclined faces vof the latter, and the leaf aS- sumes the horizontal position below the ta-v ble top, as seen in Figure 1,and then byA a) further screwing` in ofthe table, theedges of the parts 1 and l0 come together.

To remove the otherleaf, ifdesired, the

the leaf fallsdown into the inclined position as described with reference to the other leaf, and the operations are completed upon the screwing up of the screw 25, so that the parts take the position shown in Figure 1.

If in the act of stowing a leaf from the extended position, the parts at the outer end of the table stick somewhat, then thepfront end of the table top 1 will leave the inner or front leaf 7, separating the dowels 14 of these parts; and upon a further movement outwards, the studs 9 by striking the horns 8, will move the inner dowel's 13 from the central portion 10; and they will also bring this leaf 7 to such a. position that the bars 30 will be resting on the cam blocks 31 so that the leaf 7 will remain in the horizontal position; and on a still further screwing back of the screw, `the bar 21x iXed to the end frames, will strike the bar 20 fixed to the inner central slides or frames 15,v as shown in Figure 11 and so will prevent further movement of the front endof the table in relation to the central part, so that these' two parts stay together during the further unscrewing of the screw, whereupon the operation as described, namely, the opening of the table at the far end takes place. and after such leaf has dropped into the lower horizontal position, upon screwing up the table again, this end is closed as before described.

In thecase of the table being of the single loose type, one end will be similar to the end portions 1, 2. of the table shown and described, whilst the other endy will have attached to it, the inside frames or slides.'l

That is to say, the slide 15 in the case shown in the drawings, would in the case of a single loose leaf table, be attached to the legs of one end of the table. v Y

What I claim is 1. A loose leaf extension table, comprising end frames having the end portions o-f the table top secured thereto, a slide member carrying the center portion of thetable top slidably mounted in the end frames, cam blocks mo-unted on each end of the slide member, leaves carried by the end frames and slide member adapted to be inserted between theend portions and the center portions of the table top for extending the table, bars having beveled faces carried by the ma intimated vfor ,c56pmam'"wie'theV cam blocks, 'andmea'ns for" moving Vthe end frames and* sl1de"me'mber toward v` or away fromv each other,l whereby to Stow a `leaf from betweenthetop sections, the end: frames andslide member are moved apart by said means, the .leaves 'dropping so. that the bars thereon engage the cam' blocks and` when said means is operated to bring the I end frames together, the bars ridedown the cam blocks and the leaves are stowed below the table top.

2. A loose leaf extension table,comprising end frames having the end portions of the table top secured thereto, a slide member carrying thefcenter portion of the table to-p slidably mounted in the end frames, leaves carried by the end frames and slide member adapted to fit between the-end portions andv g center portion of the table top for extend,- ing the to-p and to lit below the table top in contracted position of the table, cam blocks v carried by the-slide at each end, bars mounted on the leaves adapted toengage and co- ,l

operate with the cam blocks so that the leaves may be guided for stowing below the table top or positioned between parts thereof, horns mounted on the leaves adapted to be engaged by projections on' the end frames for moving the leaves so that the barsomay be moved relative to the cam blocks for producing the desired movement of the leaves, and means for moving the endframes and slide toy 4cause theleaves to be moved'into the desired vpositio-n thrufthe operation 4of the horns, projections, bars, and cam blocks.

3. In a loose leaf extension table, the com'- bination of a plurality ofloo-se leaves, two end frames and top portions fixed thereto, a central top portion, intermediate frames fixed thereto and working in connection with the said end frames and supported one from the other, cut away parts or gaps in the end and intermediateframes adapted toreceivey and hold the leaves, means connected with a sliding part of the tabler adapted to act upon parts onv the leaves,`and to tilt same, `and move same to the horizontal positiom'and means for moving the end portions of the table towards and -awayfrom yone another.

end frames, an intermediate frame slidably the intermediate frame having its end porframes in all positions, aloose leaf carried between each end frame and the intermediate frame, projections formed on the leaves,

projections on the inner ends -of the end frames and other projections formed on the 1,15" 4. A loose leaf extension table, including` ends of the intermediate frame, the projections on the leaves extending between the projections` on the end and intermediate frames, and operating means for the table frames adapted to move said frames outvvairlly` and inwardly for bringing the projections on the framestogether` for engagement with the projections on the'leaves to 5 position alaaf in top forming position in one operation and subsequently remove them therefrom in the next operation.

In testimony whereof I have signed my name to this speeication in the presence of two subscribing witnesses. f
