FLUSH HINGE."

Specification of Letters Patent.

Patented April 20, 1909.

i Application filed. January 2, 1909. Serial No. 470,316.

To all whom it may concern:

Be it known that l, JAMns E. WHEAT, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut,have inventedcertain new and useful 'lm rovements in Flush Hinges, of which the following is a specification.

My invention relates to an improved form of flush hinge so called, that is, a hinge which when used intermediate of a table and leaf of a sewing machine and set into a mortise thereof will finish flush with the surface and not have an extended knuckle as is the case with sewing machine hinges for this purpose now upon the market.

It is the purpose of the invention to roduce a hinge of the above kind that w be durable, simple, and practicable, thus insuring, a long period of usefulness and their general application to not only. all styles of sewing machines, but other things, as for instance drop leaf tables, pianos, etc., and

to construct the hinge in any way which will;

allow it to be made from two parts of sheet metal and a single piece of wire all of which can be inexpensively produced by automatic machinery.

Upon the accompanying sheet of drawings forming a part of this s ecification, similar.

characters of reference enote like or corresponding parts throughout the several figures and of which,

Figure 1, shows a top plan view of one of my improved flush hinges. Fig. 2, is a side edge view of the hinge shown in Fig. l Fig. 3 is also a side edge view of the hinge, in an open position, and Fig. 4, is a bottom plan view of the hinge. r

Referring in detail to the reference characters marked upon the drawings 5 represents the two leaves of the hinge which are alike in construction and each contain the usual screw holes 6, any number of which may be employed. lhese leaves may obviously be of any suitable shape or design as may be best suited in style to the particular purpose for which they are employed.

The'outer edges 7 of the two leaves are bent over and disposed at a right angle to the face of the leaf forming a perfect y round corner on the inner top edge of each leaf which extends across the entire depth of the hinge and thus also forms a correspondingly transverse concave socket 8 upon their under side. The leaves are each provided with a pair of slots 9 in their abutting surfaces and are arranged to register with the corresponding slots in the op osite leaf so that when the leaves are assemb ed they will operate in conjunction with each other. These slots extend through the bent portion of the leaves as .will be noted from the drawin s and serve to accommodate an elongated s aped link 10 which is formed of a single piece of wire. In practice this link is first bent substantially a U shape, in which form it is inserted through the respective slots of the leaves and then the ends are bent toward each other and disposed into the concaved pockets 8 before mentioned, see Fig. 4. The two short end portions of this link 10 are thus arranged through the slot openings in the bent por- I tions of the two leaves while the longitudinal side portions of the link lay across the underside and in the concave pocket 8 before mentioned. The pur ose of the link is obviously to snugly holrl the two bent operating faces of the leaves together and to retain the leaves in proper positions relative to each other when in their various positions.

With the parts in the position shown in Figs. 1 and 2 and secured to the table and leaf of a cabinet as indicatedin dotted lines the effect of the movable leaf of the hinge when being raised would be to roll or turn back upon the rounded corner of the fixed leaf carrying therewith the link, which in all positions hugs the pockets thereof in a way to prevent any sliding movement of one leaf upon the other. In practice I find that when properly made and applied the hinges are very effective and operate satisfactorily.

From the foregoing it will be seen that when this hinge is spread as shown in Figs. 1 and 2, no part of either the leaves or link extends above the top surface thereof, and that a smooth finish is produced throughout save the small transverse pocket produced at the intersection .of the rounded corners, which is obviously not objectionable.

Having thus described my invention what I claim and desire to secure by Letters Patsmoothed and rounded to form an operating joint, a single Wire link arranged below the 1 face of the leaves and adapted to hold the operative ends of the leaves snugly together. edges of the two leaves together.
