nines.

Be it known'that I, O'rro It. MILKina "citizen of the United States of America,

.and resident of Holyoke, in the county of Ha-mpden, and State of Massachusetts, have "inventedcertain new and useful Improvei merits in Hinges, of which the following is a full, clear, and exact description.

Thisinvention relates to improvements 1n hinges and of a kind especially adapted for employment where the projection of hinge ear pleces or protuberances will be avoided at the junction of the hinged parts; but, on

the other hand, whereby the surface at such hinged'parts will be flush and continuous.

A hingesu'ch as exemplified by this invention is especially desirable for use on sewing machine tables of a kind known as 1 drop top tables, that is, tables constructed .with a main top and a supplemental top hinged thereto, the sewing machine being mounted on a support within a large aperture in the main top and adapted, whenithe. supplemental top is overturned, to lie horizontally on the main top to be automat1cally caused to descend into the said aperture and be concealed by the supplemental top.

a In tablesvfor sewing machines of the character just above referred to, and in, many other tables having one top section hinged to another, it is very desirable that when while table top sections are in their extended relations, and in thesame plane, there shall be no projection or obstruction above such plane to interfere with the free moving of fabrics on the table or to otherwise constitute an undesirable factor.

This inventionconsists in a hinge having 1 parts in combination and arrangement substantially ashereinafter described in con-- and set forth in the claims.

In the drawings 'Figui-e 1 is a plan view showing my improved hinge as connecting the two parts or sections of a table top;

junction with the accompany ng drawings Fig. 2 is a vertical sectional view on. line 2--2, Fig. 1, with the parts in extended relations; Fig. 3 is a'sectional view similar to Fig. 2, but showing the arts in folded-over relations; Fig. l is an e ge view of Fi 3; Fig 5 is a erspective viewof the pa1r of hinge plates inverted; Fig. 6 is a perspeotive view of the pair of pivotally' connected link bars shown nverted.

In the (ire ings,-A A re resent a pair or set of ljkdihinge plates esigned to be Specification of Letters Patent. Application filed June 30,1909. Serial No. 505,171;

Patented Feb. 1, 1910.

clearly shown in Fig. 5.

C G represent a pair of link bars having laterally extending trunnion-like lugs f at their outer or most separated ends which are engaged in the said fulcrum recesses; and these link bars have at their inner ends matching upstanding ear pieces or lugs g g d d within their rear edges,-these recesses being most and g united by the transverse pivot pin h.

The combined bulk of the ear pieces is such as to substantially fill the said opposed recesses a, a of the hinge plates, and their upper edges are flatyas shown at i, so as to constitute a surface continuation when the parts of the hinge are in the relations shown in Fig. 2, flush with the top of the frame plates. 5

The aforementioned lugs Z) 6, which have the fulcrum recesses (Z d in the rear edges thereof,-are longitudinally continued in parallelism for the entire length of each frame plate so as to make adownwardl opening channel, the side. walls of whic constitute a guide for eaclrlink bar and strengthen the hinge construction as a whole.

j 7' represent spiral springs which are preferably provided for coaction with the link bars for exerting a pressure thereagainst to force them toward the hinge plates A.

m and m representlips or flanges pro: jecting more o nlcss transversely from the lower surfaces of the link bars and extendin transversely acrossthe entire widths thereof ad acent the r plvotally connected ears,- these members an and m serving, when the hinge is doubled up as shown in Figs. 3 andfl, as guards to prevent the entrance of dirt into the channel-like openings inthe hinges,

which, in the absence of these guards, would the hinged parts are opened. in the relation shown in Figs, 1 and 2 will'engage under the edge portions of the stationary hinge plate at either side of the recesses therein for preventing any possibility of upward movement of the hinge connected leaf relatively to the table top even although a pressure from underneath might be exerted against the hinged leaf.

I claim 1. In a hinge, in combination, a pair of edgewise matching frame-plates having opposed recesses within their matching edge portions, a pair of link bars fulcrumed to the frame plates, having their inner ends pivotally united one to the other, and comprising means, adjacent their uniting pivot for substantially filling said opposed resesses, and constituting a surface continuation flush with the top of the frame plates.

2. In a hinge, in combination, a pair of edgewise matching frame-plates having opposed recesses within their matchin r edge portions, a pair of link bars fulcrume to the frame plates, having their inner ends pivotally united, one to the other, comprising means, adjacent their uniting pivot for sub 'stantially filling said opposed recesses and constituting a surface continuation flush with the top of the frame plates, and springs,

' under the link bars, for forcing the latter toward the frame plates.

3. In a hinge, in combination, a pair of edgewise matching frame-plates having 0pposed recesses within their matching edge ortions, a pair of link bars fulcrunied to the rame plates at points remote from the matching edges of the latter having at their inner ends matching ear pieces pivotally united, said ear pieces havin acombined bulk to substantially fill sai opposed recesses, andhaving their upper portions'tlat to constitute a surface continuation flush with the top of the frame plates.

4. In a hin' e, in combination, a pair of 'edgewise matc ing frame plates having opposed recesses within their adjacent edges and each having remote from such edges opposed depending lugs having fu l crum resaid oppose continuation flush with the top of the frame cesses within the rear edges thereof, a pair of -link bars having trunnion-like lugs at. their outer ends engaged in said fulcrum recesses,

having their inner ends pivotally connected together and constructed with parts to substantialy fill the opposed recesses in. the frame plate.

5. Ina hinge, in combination, a pair of edgewise matching frame plates having opposed recesses within their matching edge portions and adapted to be litted in edgewise opening mortises. in the arts to be hinge connected, a pair of linli bars fulcrumed to the frame plates, ,having their inner ends pivotally united one to the other, formed with portions adjacent their unitin pivot for substantially hlling said opposed recesses and making a flush surface continuation of the frame plates and said link bars having at their under portions and adjacent their connecting pivot downwardly extended transverse ribs for forming closures for the edgewise opening mortises when the hinge connected parts are in folded relations.

6. In a hinge, in combination, a pair of edgewise matching frame plates to be sccured to the parts to be hinge connected, said plates having'opposed recesses within their matching edge portions and the edge of one of said plates having anextension for engaging under the other for preventing a movement, in an upward direction, of the one late relatively to the other, a pair of link hars fulcrunicd to the fraineplates having their inner ends ivotally united one to the other and comprising ortions adjacent their uniting pivots for su stantially filling recesses, constituting a Surface plates.
