Application filed August 16, 1916. Serial No. 115,267.

To all whom it may concern:

Be it know that I, DAVID SMAILIE S ITH, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new an'duseful Improvements in Extension-Tables, of which the following is a specification.

My invention relates to improvements in extension tables of the kind in which the extension portions or leaves are adapted to be carried beneath the end sections and to be raised to fill the space between the same when the table is extended, and the'object of my invention isto devise a table of this class which is eflicient, very simple inconstruction, and capable of being manufactured and sold at a low cost.

I attain this object by the construction illustratedin the accompanying drawings in p which Figure 1 a plan view of the table when closed, the top being broken away to show the extension portions.

Fig. 2 is a transverse section on the line a-b of Fig. 1. i

Fig. 3 is a transverse section on the line o Z of Fig. 1, showing the extension portion raised prior to lowering into place between the extended end sections.

Fig. 4 is a view similar to Fig. 3, but showing the position of the extension portion when raised intoplace in the extended table. i i F ig. 5 is alongitudinal elevation onthe line c-f of Fig. 1. I i

F 6 is a .detail view, lILPBI'SPGCtlVG, showing the methodof mounting the hinges.

Similar figures of reference indicate simi lar, parts throughout the several views.

1 indicates the middle section of my table,

.which section is stationary and to which is secured the supporting leg 2 which is of any approved design. 3 and-tindicate the movable halves of thetable top, which halves may be provided with supporting legs (not shown) of any desired form, although in a l ierlestzal table, as illustrated, such legs are .not required. The two halves, of the table top are adapted and arranged. to be separated and closed by hand by theusual or any preferred arrangement of slidii'i bars,

.ich as shown in Figs. 1' and 2, in w ich 5 and 6 are bars having oneend secured to the table half 7 and 8* are bars having one end secured to table-half 4, while 9 and 10 are bars interposed longitudinally between the bars 5 and 7 and 6 and 8 respectively and connected to them by sliding dovetailed joints 11. The bars 9 and 10 are not sooured to either table-half, but to the stationary middle section 1, from which it will be seen that the two table-halves may be drawn apart, or pushed together, as may be desired. Securedto the middle section 1. are guide bars 12 and 13, between which guide bars slidably mounted a flat member 14:, which member rests on top of the middle section 1 and moves th ereon' when the table is being opened or, closed. Secured on the top side of the member'l lat each end thereof are Crossbars 1 5 and 16, the bar 16 being extended, as shown in F 1, so that its ends maybe'engaged during the opening and closing of the table by stops 17l8 and 19-20 secured to thesliding bars 5 and 6, as here inafter described. Each crossbar and 16 has secured on its inner face adjacent, its lower edgethe pieces 21 and 22 respectively having slots 23 in each end in which the hinges 24 and 25 operate and they are also provided with blocks 2627 and 28.29 respectively, which serve to act as guides for the hinges and prevent lateral movementof the extension portions when being raised into place. I i The extension portions or leaves are formed as shown more particularly in Fig. 2, that is, having an intermediate portion 30, to which extensions 31 and 32 are hingedly connected by suitable hinges 33, so that the extensions may be folded under the intermediate portion, as shown in Figs. 1 and 2, or opened out to the full width of the table, asshown in Figs. 3 and 4; Secured to the underside of the intermediate portion are the hereinbefore mentioned hinges 24% and 25, as shown in Fig. 8, the free leaf of each hinge being disposed, as shown in Figs. 5 and 6, 'in the slots 23 of the pieces 21 and 22 hereinbefore mentioned, and vertically movable therein so that .a floating hinge connection is formed between the leaves and the member 14-. The portion 30 is not mounted on the hinges adjacent the hinge joints, as is the usual method of mounting, but is disposed toward. and supported on the outer ends of the hinges at a 3, this distance being such that the folded leaf when. swung upwardly top of the sliding bars ofthe table'to "allow of the extensions 31 and 32 being unfolded.

I may here state that'the hingesfie and 25 need not necessarily be disposed the slots 23 so as to be vertically movable therein, as the hinges be secured to the erossbars 15 and 1:6 as well as to the intermediate portion 30. floating hinge connection, however, is the preferred conr e e B in eet s a di tanc piec .e we to th ull lersiel f th int me at Pe tien .3 te maintain th xten ions .31 a :3 n Paral l Po i onhe. e li al pe t i vo th ex ension eer s i a ow inEies- 1.2 1162, that is te say, t ext ien .3 2 are n r meliy e d d d r he-inte m diate nan- .t n' 30 Wh l th biase 24: en 25 a e e ide y am un 3 their x reetire sle 23- Th e t nsi .l exee th re z ieely 9.1.1. ten .ef th an member 14: and new en the sl d e n an end it rviii he n t ced that t ex are net .e eeeeterl 499 ny P r -0 he :teblee new xt e lieble the b 'e he re e e pilled apart in th vusual m n n-n il t e a e e erm th fi s xt eie i ne 't en a iieh it Will he e s re s di p ee trel y f t e able i s then e ho s in T ie rert ei ei e lei-ha on i s n -ewe a d 2,5. air-er th m nn e ewn in E g 5 and r d th ex ii ieii 3 an i nei d ea -the fel wi tii as shown Fi 3, wh neun r the extended leaf is allowed to drop to be sup.- .riorted ,on the sliding bars of the table and leyel i h the extended table-halves 3 and it .W-h e m y then b l e tr e the tension leaf; Should further extension,
