IMPROVED EXTENSION- TABLE Eo ALL PERSONS To WEOM THESE PRESENTS SHALL COME:

Be it known that I, GEORGE F. FOLSOM, of Roxbury, in thecounty of Norfolk, and Sta-te of Massachusetts, have made a new and usefuly improvement in Extension Dining-Tables; and `do hereby declare the same. to be fully described in the following specification, and represented in the accompanying drawings, of whi'oh- Figure 1 is a side elevation. v

v Figure 2, a longitudinal and verticalrse'ction, and

Figure 3-an end elevation of it in a contracted state, but with its end-ilaps or leaves raised into horil zontal positions. v

Figure'l is a vertical section ofthe mechanism applied'to each side of the` table in order to eiiect the elevation of. either or both the auxiliary leaves to a level with the table top.

.Figure 5 is a horizontal section of the upper -part of the frame of the table. The said frame is composed of' three frames, A B C, two ofwhich, A and C, slide horizontally within the middle one, B, as a drawer does in its case, and in directions toward and away from eachother or its middle,

Each of the frames AC I support on three legs, a a b, extending down from .it in manner as represented in the` drawings.` Furthermore, in order to steady each frame A or C, o'r to cause it to move rectilinearly while being moved, there may extend horizontally from it, near its middle, a round metallic rod, c, which may enter, iit, and slide within a tube, d, i'ixed in the cross-bar e of the frame B. The table top is composed of two boards or main leaves, D D, each of which, at or nearits outer edge, is ailxed to one of the frames A C, and arranged therewith in manner as represented; There is betveen .each 4of' the two boards D D and its supporting frame A or- C, a horizontal space for reception of one of two auxiliaryleaves E E when the -table is contracted or leaves D D, at its outer edge, 1s hinged one of two turning leaves F F, the hinges thereof` being shown auff in gs. 1 and. Each of' the leaves F'F is to `be capable of being turned from a. horizontal positiondown into a vertical one. In order to hold each leaf` F in a horizontal position, I hinge to the under side of ita bracket, G, formed and arranged thereon as represented in the drawings. This bracket by its `own gravity will dropv in to a vertical position and against a stop, t, when the leaf F is moved to a horizontal position. By pressing against the frame A or C the bracketwill hold up the leaf in a vertical position. When the-table is extended, or either frame A or C is drawn outward to the extent ot' its motion away from the middle ofthe table, it becomes desirable to have some means of elevating'the auxiliary leaE of Athe extended part up to a level with the table top D D. -This I eiect by mechanism which may be thus explained: In each side of the frame B is a long horizontal channel or groove, y, for reception of two.elevators H H, formed with cams t/ t to rest `against pins or similar counter-cams, i2', arranged in the groove g, the whole being as.v shown in iigs-4 and 5. From each 'of the elevators a rod, lc., extends and is jointed Vto an arm, Z, projecting from the next adjacent turning leai F. The said rod c slides freely through an ear, m, extending inward from the elevator. "Such rod has ahead, n, at its inner end, the whole being so that after either frame A or @may have been fully rods 7c Connected with suchleaf to move theirtwo elevators endwlise., During this endwise movement of each of such elevators, their cams, by being drawn against the counter-hams, will cause the two elevators to rise vertically and force upward the auxiliary leaf resting on them. Each of' the elevators in the mean time will be drawn a short distance underneath and against the 'next adjacent leaf D of the Atable top, whereby they will operate to support it as well as theauxiliary leaf E,` and thus prevent any weiv'ht'placed on the leafD from breaking it'down. When the table is closed the leaf D rests on the leaf` rE, and the latter on the frame B. Ii' when the table is extended we may be desirous of' contracting it, the first thiner to be done is to raise the brackets G and drop the two turning leaves into vertical positions. This will cause each pair of rods /c to be moved inward Within their two elevators H, and so as to allow the elevators. and the auxiliary leaf E upheld by them to drop downward to positions which will bring the top of the leai` E to a level below that of the bottom ofthe next adjacent leaf D. Either or bothy the table-frames A C may next be moved'inward.

Stasi The table may be contracted so as to bring the two leaves D D close together and over the Iwo anni/liar)y leaves E E, or it may be so contractedthat one of the leaves E will be wholly underneath its leaf' D, and the other leaf E be between and raised up to a level with the two leaves D D. y

This table differs from other extension-tables in use in having the auxiliary leaves E and their operative mechanism arranged with and applied to the main and turning leu-ves D D and F F, and the three frames A C, substantially in manner and so as to operate as described. Furthermore, each turning-leaf bracket, instead oi' being hinged to the frame or part of the table to which the turning leai` is iixecl, is hinged directly to the turning leaf. By this application of thelbraeket its own weight, while the leaf is being raised, will cause the said bracket to fall intoa vertical position, or one for holding the turning leafV up in a horizontal position. table with but one auxiliary leaf, E, may be made by having but two leg-frames instead of three, A B C, and providing the same with *mechiinismfor operating the auxiliary leaf, as described, such table being furnished with either one or two of the t'nrhing leaves.

What I claim in the said-table as of my invention is as follows:

I claim the combination, as well as the arrangement, of an auxiliary leaf, E, and mechanism, viz, its` rods k, elevatore II, and Vtheir counter-cams, or the, equivalents thereof, for operating it, as dcseribed,-with two legframes, and their inain leaves D,\one of such leg-frames being constructed with a space or recess arranged below the main leaf and for the reception of the auxiliary leafVA when the table is closed, as` described.

I also elaine the combination, as well as the arrangement, of` two auxiliary leaves E E, and mechanism for operating them, as described, with the three frames-A B C, andtheir main leaves D D, arranged together as specified. l Y

` I also claim the combination, as well as the arrangement,of two turning leaves F F, two main leaves DD,

three of the iframes A B C, as described, tw'o' yauxiliary leaves E E, and mechanism, viz, its rods k, elevators H, and their counter-cams, 4or the equivalentstliereof, for operating such leaf` or leaves E E, as described.

I also claim the peculiar mechanism, in combination, applied to each turning leaf, and for operating each of the auxiliary leaves, s'ueh being the slide-iods k12, and the elevators, and their countereau1s,or their equivalents, as set forth.

I also claim the combination, two leg-frames one auxiliaryr leaf E, and m equivalents thereof, for operating such leaf, as described.

' I GEO. Fm FOLSOM.

as well as the arrangement, of one turning leai- F, two main leaves D D, cchanism, viz, its rods k, elevators H, and their counter-earns, or the Witnesses:
