AWIG'NOR. To THE emcee manna-c- TUBING COMPANY, A "CORPORATION or irER'sEYL v Application fi led flugnst 12,1919. Serial 'Noc3!7-,'071.

To all whom it may concern: I

, Be it known that I, EMIL A. Kerr, a citizen of the United States, residing at Newark, in the county of Essex-and State of New Jersey, have invented certain :new and use ful Improvements in Hinges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates toihinges, morepartic-ularly of the so-called flush-type and has for an object to provide a'hinge which is particularly adapted for, the folding or cover leaf of a drop-head sewing machine cabinet and which will permit said leaf to be opened thruan angle 01 substantially 270.

Another object-of the invention :is to provide a hinge which may be set substantially flush with the exposed surfaces of. the cabinet-top and cover and which will not offer any objectionable or unsightly protuberances in either closed or open position.

A further 'obfect of the invention is to provide a hinge which will permit thecover leaf to be opened or swung through an angle of 270 from a horizontal position upon the cabinettop to a pendant vertical position at one end of the cabinet-top, and at the same time dropped sot-hat itsupper edge will not project above the level of the upper surface of the cabinet-top. 7

Still further, the invention has for an object to provide a hinge which will elfect the elevation of the hinge-end of the cover-leaf as said leaf is being closed, thereby preventing damage due to rubbing or other harsh contacts between the cover-leaf and cabinettop.

WVith the above and other objects in view, as will hereinafter. appear, the present hinge comprises a pair of hinge-leaves each of which is preferably formed of bent sheetmetal and comprises a pair of spaced vertical walls and horizontal attaching ears. The spaced walls of the hinge leaves embrace the opposite ends of a distance link which permits the cover of the cabinet to drop as it is being opened out so that its upper edge will not project above the level of the exposed surface of the cabinet-top. The stationary leaf member of the hinge, i. e.. the one which is secured to the cabinettop. is provided at the upper edges of the spaced vertical walls with very slight upward extensions-affording abutment surfaces against which the movable leaf-10f the reacts as a lever to lift the outer end of th'e distance link as the cover of the :oabinet is being clos'ed, thereby ',-p-i '-eventin;g-

upper edge of the-leaf from pressing --or-rubb1n'g against the cabinet-top.

, .Invtheaccompanying-drawings, lr'is a SlClB GlQVit-blOII-"OEE' the hinge in open p'o sition, fragments of the "cabinet top and swinging cover being shown insedtion Fig.

2- is a. similar view showing the lever-action of the movable leaf of -hinge it lifts thedistance link when the hinge is-being closed. Fig. 3 is a similar'vie'w showing the hinge closed. F ig tis amend: elevation ot the hinge in closed position as shown in 3. Fig. 5 is a top plan view of the hi'nge opened -180,--and Fig. 6 is a view-similar to Fig. 3but 'sh0wing thehinge in section to reveal the distance link inside elevation. 1

In the preferred embodiment of the'invention, as illust'nitechthe hinge coinprises'astationary leaf 1 and a movable leaf Qwhich "are pivotally connected together by means of the distance link 3. The stationary leaf 1 comprises a piece of sheet-metal folded at 4 to provide the spaced parallelvertical wall-s 5, the lower extremities of :whichare bent outwardly in opposite directions to form the a-tta-chingears '6, 6. This leafof-thehinge is adapted to be seated Within asuitable "erti-cal slot 7 cut inwardly from theend edge of "the top-board {not the "cabinet. The upper edges 8,8 of the walls 6, 5 are substanti-a-lly straight throughout the major portionoi their length-and areset substantially flush with the upper surface 9 of said topboard (4. i

The spaced

walls

5, 5 are prefe'rablyprov-ided at their outer corners with slight upward extensions affording the slightly ra'ised abutment surfaces 10, 10. For the sali-e of clearness, the elevation o-fthe surfaces 10 1.0 above thesurface 9 of the top-board A ise'xaggerated in the drawing. In practice the difl erence in elevation between the surfaces 9 and 10 may be approximately 1/64 of an inch and is wholly unobjectionable. The outeror exposed ends 11 of'the

walls

5, 5 opposite the fold l, are curved "to match and set flush with the ogee or other fi'l llshlllg curve at the end of the top-board a. The ears 6 are let into suitable depressions 1n the under surface of the board a. F

The movable leaf 20f the hinge is also formed of sheet-metal which is folded at 12 to form the

spaced walls

13, 13, extensions of whichare further bent to form the attaching;

ears

14, 14, lying in a common plane with which the fold 12 makes an acute angle. The

ogeecurve or otherfinish at the hinge end of 15 i r the covert; The distance-link 3 is pivoted upon the pin 17 between the walls "5 of the stationary leaf 1, and is formed with a movement limiting slot 18 which is curved concentrically with the pivot pin 17 and th'rough which passes the pin 19. l'n'the specific embodiment of the invention; illustrated, the angular extent of the slot 18 isabout45". The upper edge 20 ofthe link 18 is'shaped' so as to be flush with the'surfaces 8 and 10 of the stationary leaf l when said link lies horizontally, in which position the outer extremity ofthe link projects horizontally beyond the end of the board a and extends between the end ears 16 of the walls 13 of the movable leaf 2, being pivotally connected to the latter at 21.- 'The lower-edge 20 of the distance link, is curved to match the ogee curves of both the table-top and coverboards,as shown in Figs. 2, 3 and 6.

lVhen the cover '6 is opened to .the posi tion shownin Fig.1, the extreme upper edge of said cover is substantially at the level of the upper surface of the top-board at. As the cover-is being closed the corners 22 at the outer ends of-the folds -between the ears 14c and walls 13 strike the abutment surfaces I 10 of the stationary leaf .1, as shown in Fig.

2, and act as the fulcrum of a lever formed by the hinge-leaf 2 to lift or swing the distancelink '8 upwardly about its pivot'17, thereby elevating the pivot 21 and cover I) to the position shown in Fig. 3.- The metallic contact between the corner 22 and the upper edges of the walls 5 prevents rubbing --of the-edge of the cover 6 against the upper surface of the cabinet-top a.

- It will be noted'that in the position shown in FigB the movable leaf 2 is disposed mainly betweent'he stationary leaf'l and the pivotal connection 21; In other words, the pivotal connection 21" is disposed nearer theupper than the-lower limit of the movable leaf. Further, the slot in the movable leaf isopen for a space of more than 180 around the pivotal; connection 21. These provisions permit the movable leaf to be swung throughan angle of substantially 270 from the position shown in Fig. 3 to that shown in Fig. 1.;

The invention is not to be understood as limited to the exact form and arrangement of partsshown and described, as the present construction is obviously susceptible of material modifications within the scope of movable leaves, and a link-bar connection between said leaves, one of saidleaves being constructed and adapted to react as a lever against the other leaf to lift the link-bar and effect theelevation of themovable leaf as the latter is being swung from open to closed position: 1 y

2. A hinge comprising a stationary leaf having a surface'ad'apted to be set substantially flush with the upper surface of a table-top member, a movable leaf having a surface adapted to be set substantially flush with the surface, of a cover member, and a link-ban connection between said leaves, one of said leaves having a portion projecting slightly beyond the said adapted to be set" surface which is flush with its supporting member, such projecting portion serving to coact with the other leaf. independently of said link bar to prevent contact of the cover with the table-top as said cover is being swung between open and closed positions.

3. hinge comprising a stationary leaf, a movable leaf idisposedabove the stationary leaf, and a link-bar pivotally connected at its 'opposite ends to-said leaves, the movable leaf being disposed mainly between the stationary leaf and the point of pivotal,
