Y 'cAsnMENr HINGE.

Application led September 30, 1925. Serial No. 59,718.

the. window or door pivoted'thereby in a' certain position.

It is another object ofy this invention to provide a hinge havinga pair of members hinged'together, each having a clamp plate associated therewith and having means for clainping'said clamp plates together.

Other objects and advantages of the invention will be made evident hereinafter. Referring to the vdrawings in which- AI illustrate my invention Fig. lis a diagrammatic view showing the utility of the easement hinge of my` invention.

Fig.` 2 is an elevational view'o'f the A`casement hinge of lmy invention.

Fig. 3 is a section'taken'onthe rline of Fig. 2.

Fig. 4 is a fragmentary section showing the manner in which'the hinge members arey clamped so. as to be relatively non-swingable.

In Fig. 1 I show a easement 11 surrounding an opening 12 which is closed by a swinging member such as a door or easement window 13. The member 13 is hingedly secured to the Casement 11 by means of a easement hinge 15 incorporating the features of my invention.

lith reference to Fig. 2 the hinge 15 has a primary hinge member 18 and a seconda-ry hinge member 19. The primary hinge inember 18 is preferably secured to the easement 11 by means o'f screws 2O which are projected into the easement 11 through openings 21 provided in the primary member 18. The secondary hinge member 19 is secured to the member 13 by screws 23 which are extended into the member 13 through openings 24 provided in the secondary hinge memberl 19. The primary hinge member 18 has a pair of outer cylindrical portions and the secondary hinge member 19has a central cylindrical portion 26 which is placed between the outer cylindrical portions 25 of the primary hinge member 18. A hinge pin 27 is extended` through the cylindrical portions 25 and 26.01: the primary hinge meinbei 18 and the secondary hinge member 19 for -hingedly attaching-these members together. A plug 28 is inserted into the lower part of the lower cylindrical portion 25 of thc primary hinge member 18. pin 27is preferably secured rigidly to' the lower outer cylindrical portion 25 of the primary hinge member 18.

The primary hinge 'member 18 is provided with anotch 30 and the secondary hinge member 19 is provided-with a notch 31 which aligns with-the notch 30,` asclearlyfshown in Fig. 2Q Placed inthe notches 30 and 31 concentric with respect to the hinge pin 27y isalower clamp plate33 the hinge pin 27 extending through a central threaded Opening 34 of the lower clamp plate 33. As clearlyshown iii-Fig. 4,the lower part of the pin 27 is smaller in diameter than the upper part,

vwhich upper part is threaded at 35 to permit the lowersclamp plate to Ybesecured thereto. The primary hingeplate V18 has .".t'projection4 l3''which 'extends and lits loosely in a lslot 37 formedfin. the periphery ofthe lower clampplate 33. A lower facej 38 of the yclamp plate' 33 engages a face`39 ofthe primary hinge member 18, which' face. 39y defines 'the y'lower' part vofthelnotch 30. Anupper clamp plate"41is"placed in thenotches 30 and 31, having a concentric opening 42 through which the pivot pin 27 extends. The upper clamp plate 41 has a slot 43 into which a projection 44 of the secondaryhinge member 19 extends, this projection 44 fitting loosely in the slot 43. An upper face46 of the upper clamp platev41 is engaged by a face 47 of the secondary hinge plate 19 which confines the upper part of the notch 31. A lower face 49 of the upper clamp plate 41 is adapted to rest in engagement with the upper face 50 of the lower clamp plate 33.

When the hinge'is in non-clamping position, as shown in Fig. 2, there is a space 52 between the lower face 38 of the' lower clamp plate 33 and the secondary hinge member 19, and there isa space 54 between the upper face 46 of the clamp plate 41 and the lowerface of an arm 55 of the primary hinge member 18. j y

The upper end of the pivot pin 27 is threaded as indicated at 577, and a clamp nut 58 is threaded thereonto, a lower face 59 of The hinge Cil the nut 58 engaging an upper face 60 of the arm 55 of the primary hinge member 18.

In Figs. 1, 2 and 3 the primary and secondary hinge members of my invention are not clamped together and therefore the member 13 is free to swing on its pivot. IVhen it is desired to retain the member 13 rigidly in a certain position, the nut' 58 is advanced downward en the upper end 57 of the pivot pin` 27 so that the parts occupy a position, as shown in Fig. t. With reference to Fig. 4t, when the nut 58 is advanced downward on the pivot pin Q7, the pivot pin is' moved upward relative to the parts of the hinge.V Since the lower clamp plate 33 is rigidly secured thereto it is moved upward with. the shaft. The upper clamp plate t1 is lifted by the lower clamp plate 3?) and is brought into engagement with the lower face of the arm 55.

At this time the upper face of the lower clamp plate 33 is forced firmly into engage ment with the lower face 49 of the up 3er clamp plate 41. Suiiicient friction is thereby obtained between these two faces to prevent a relative swinging ofthe primary and secondary hinge members 18 and 19 which are locked to the lower and upper clamp plates 38 and 41, and therefore the member' 13 is locked in any desired position as indicated by dotted lin-es 6st inig. 1.

From the foregoing description the utility of my invention is plainly evident. The design of the hinge 15 is rather attractive and can be made in any proportion to suit the needs. The nut 58 is so situated that it is easily operated and the hinge may be readily locked in any desired position.V The different parts of my invention are readily assembled and dismantled. It is preferable to make the threads on the lower part of the enlarged portion of the hinge pin 27 eoarser than the threads 57 at the upper end thereof so that in operating the nut 58 the hinge pin will not be loosened in the opening of the lower clamp plate 33.

I claim as my invention :f Y

1. A hinge of the class described comprising: a primary hinge member; a secondary hinge member; a hinge pin by which said ,primary and secondary hinge nembers are hingedly secured together; a lower clamp plate adapted to be engaged by and moved with said primary hinge member; an upper clamp plate adapted to rest in 'engagement with said lower clamp plate, said upper clamp plate being adapted-to be engaged by and to move with .said secondary hinge member; and means for clamping said upper and lower clamp plates from relative rotation, said primary and secondary hinge members having adjacent notches into which said upper and lower clamp plates extend. 2. A hinge of the class described comprising: a primary hinge member; a secondary hinge member; a hinge pin by which said primary and secondaryrhinge members are hingedly secured together; a lower clamp plate adapted tovbe engaged by and moved with said }j rimary v hinge member, said hinge pin being rigidly secured to said lowerclamp plate; an upper clamp plate adapted to rest in engagement with. said lower clamp plate; said. upper c lampA plate being adapted to be engaged by and to move with said secondary hinge member; anda nut adapted to be advanced onto a threaded end of said hinge pin in a manner to force said lower clamp plate into non-movable contact with said upper clamp plate.

vIn testimony whereof, I have hereunto set my hand at Los Angeles, California, this 24th day Orsept i925. y
