12 Claims. (Cl. 216-171) This invention relates to an improvement in hinges and more particularly to the single knuckle type. 1

The preferred embodiment of the invention discloses a hinge having an arrangement for preventing the removal of the leaf elements from each other except at a predetermined point.

Prior to this invention hinges of the single knuckle type have been formed from leaves which, while often exact duplicates, produced a dissymmetric unit when assembled. The result ofthis dissymmetry amounts not merely ,to an artistic objection but indicates that; by reason of the reversal of the connecting leaves, the attaching portions are not alike. Consequently, it sometimes occurs that mortises are incorrectly cut into the door and jamb simply because the workman has had to cut dissimilar mortises and located the door mortise on the jamb. The'present invention discloses a pair of hinge leaves, the shank portions of which are of the same size and inthe same plane. This is a distinct advantage since it permits the use of symmetricmortises in both door and jamb, the mortise being also symmetric with respect to its own center line. Since the mortise in both door and jamb are identical in height, depth and location, no error in mounting a hinge of the type hereinafter disclosed can occur. A further disadvantage of currently manuiacture'd hinges of'this type will be noted' from the fact that due either to inaccurate manufacturing or improper mounting or assembly, an unsightly gap occurs between the engaging surfaces of the upper and lower knuckles. The present invention, through the provision of a collar attached to or abutting one of the knuckles and having a recess into which the other of the knuckles projects, overcomes this objectionand at the same time provides a lubricant reservoir -for the relatively 'movable elements; It is by means of this recess that any lubricant applied. to-thehin'ge is concealed'from view and prevented from appearing on the outer surfaces of the A still further objectionto the oursometimes occurs that a door supported'by'a hinge of this type receives an upwardly directed force which tends to or actually does disengage "the'hinge elements. To prevent this, the present i nvent'ion' discloses means by which to lock the elements in operative relationship through the use of the same collar which constitutes the lubrij cant retaining element.

normal relationship to each other;

movable elements; provision of symmetric leaves 569 for permitting symmetric mortising; and a lubricant retainer for the relative movable elements.

Other and further objects of the invention will be more clearly understood from'a consideration of the following specification which is taken in5 conjunction with the accompanying drawing, and

Referring to the drawing and particularly to Figure 1, the invention, generally indicated by ,the referencev numeral 10, is shown. comprising a pair of elements 11 and 12. The element 11 comprises a door mounting portion 13, a shank portion 14 and a knuckle 16. Openings 17, in the portion 13, are adapted. to receive screws for attaching. the element to a door. The element '12 comprises a frame mounting portion 18, shank portion 19 and a knuckle 21, and is adapted to be attached to' a frame by means of screws which project through openings 22 in the portiorilS.

The shank'portions 14 and 19 project from one edge of the portions Band 18. The knuckle 16 is integrally formed on the upper portion of the shank 14 and terminates at its lower end in a fiat 29 hearing face 23. Similarly the knuc kle 21 is formedon the lower portion of the shank 19 and terminatesat its upper endlin aface 24. It is pointed out that, although the elements 11 and 12 cal, it iscontemplated to make use of a hinge of this type for purposes wherein one of the elements may be entirely disproportionate to the other. For example, a hinge of this type may be utilized to support an automobile door or anyl other door in which the mounting thereof is not in accord with the standard entrance door mounting in whichthe elements of -'a hinge are substantially duplicate. V

Openings26 and 27, drilled axially a limited depth in the knuckles 16 and 21 from the surfaces 23 and 24, are each adapted to receive an equal portion of a pivot pin 28. The opening 27 is preferably a drive fit for the pin 28 to prevent removal thereof from the knuckle 21. This knuckle face 23 of the knuckle 16. iThisrecess'acts'as a reservoir for retaining surplus lubricant and also as a means for concealing any gap wlnch ma yoccur between faces 23 and 24 which may result from an inaccurate mounting of the elements. .frhe pe phera ed .Q -the co a i pr f rably semh ma lin s c i n andpreieets e nd th .1 tera1 eonfines or both k uckl tei orm a shoulid r 'Aslot 33,..of slightlyereate Width th n the th ckne s 1 f rshankre t ens or is out in th pe ipheraledse o th q a 29 t pu pose of w e wi here ft rb des r ed- Adjacent the shoulder B2 and located centrallv on th shank 1. isa 9tel1 wh ch ma eoni m t th contour o the sh uld 3 l we Wa l-of the notch '34 is adapt d o en a e the "lower surface of the shoulder 32"to prevent sepa at n o h el ments 1 a d 12- ".Theslot 3.3; when the elements are located in a predetermined relative position, registers with they shank portion 141, .since the slot isof awidth and. depth to re eive a d port o e elements may be disengaged.
