JOSEPH H. SHEARD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO DAVID LUPTONS SONS COMPANY, OF PHILADELPHIA, IPENNSYLVANIA, A CORPORATION OF PENNSYLVANIA HINGE Application filed September l4, 1928. Serial No. 305,897.

This invention relates to hin e construc-' resistivity to hold a structure supported thereby at any desired open position without the assistance of independent securing means.

The primary object of this invention is the provision of an improved type of friction hinge, the engaging components whereof are of a nature to withstand atmospheric action and will not bind or rust under continued exposure.

Another object is to provide a hinge of the above noted character including adjusting means whereby the requisite co-eflicient of friction, to ensure continuous serviceability, may be maintained.

A further object is the provision of a friction hinge devoid of projecting parts of an obstructive or interfering character, the same being capable of adjustment without the use of special toolsor other equip- I ment.

A still further object is to provide hinges of the type referred to that are simple in design, cheap to manufacture, and which are devoid of complicated or expensive parts.

lVith the foregoing and other objects in view, the nature of my invention will be best understood by reference to the accompanying sheets of drawings, illustrative of convenient embodiment thereof, which will now be described in detail; it being premised, however, that various constructive changes and other arrangements of the several parts may be resorted to, without departing from the spirit or scope of said invention, as defined in the appended claims.

In the drawings Fig. I is a respective view of one form or close up type of friction hinge embodying the present improvements.

Fig. II is an exploded perspective view of the several hinge components in disassembled relation.

VIII is a topplan view of the same; an 1 Fig. IX is a front elevation thereof.

Like characters of reference are applied to corresponding parts in all the views.

Referring more particularly to Figs. I to V, inclusive, the structure chosen for convenience of illustration comprises a metallic j amb or window frame 1, whereof the perimetric rails are formed from bar stock of Z-shaped cross-section; while the sash frame or casement 2 is fabricated from corresponding material, and closes against the window frame 1, withits face flange 3 overlapping the complemental flange 1 of the latter frame; said parts constituting no feature of the present invention and being merely referred to byway of clarifying its adaptation in use. t

My novel friction hinge, comprehensively designated 5 in Figs. I and II, comprises a male component or stationary member 6 with a female component or movable member 7 The former of these components or the stationary member 6 embodies an irregular configured body portion 8 with a planarly offset anchorage pad 9 having apertures 10 therethrough whereby it is secured to the window frame 1 by the medium of appropriate attaching means, such as screws 11. The stationary member body portion 8, remote from the offset pad 9, is reduced in thickness and retroverted to provide a grippage overlap 12 which, with said body portion, affords a U-sl1aped-clevis, for a purpose later on explained. Holes 13, 14: are, respectively, formed in the body portion 8 and grippage overlap 12, while the former-or both-of said holes is screw-threaded for engagement by a stud bolt or adjuster pintle 15.

The other hinge component or movable member 7 embodies co-planar anchorage pads 16, 16 convenientlyalthough not essentiallydisposed in rectangular relation, having apertures 17 whereby said member is attached to the sash casement 2, through the medium of cap screws 18, for example. Integrally formed with the movable member 7 and appropriately at right angles thereto, is a lateral outset oraperfured car 19 constituting the journal portion of said movable member. This lateral outset or apertured ear 19, it will be seen, is reinforced relative to the anchorage pads 16, 16' by its integral heel and brace portions 20, 21, respectively.

In connection with my novel friction hinge 5, I make use of friction-creating means such as washers 22. These washers 22 constitute an important feature of my invention which is to make the friction surfaces of materials that will not bind or rust together under exposure, and yet will offer a sufiiciently high co-efiicient of friction. To this end I fabricate the hinge components before described of such material as steel, malleable iron forgings, or the like; whereas, the washers 22 are preferably made of bronze, brass, copper, lead, hard fiber or other suitable material, as I find such combinations of unlike metals or materials effectively restrain rela tive movement of the respective parts one over the other, without undergoing appreciable wear incident to continuous usage. Accordingly, in assembling the hinge components, I preferably employ two of the washers 22, one disposed above and the other below the journal portion or apertured car 19 of the movable hinge member 7, when said ear is inserted in the U-shaped or clevis end of the stationary member 6, pivotal connection between these members being obtained by application of the adjuster pintle 15, in anobvious manner.

Referring now to Figs. VI to IX, inclusive, it is to be particularly noted that while the hinge assemblage illustrated therein differs somewhat from the disclosure hereinbefore set forth that the fundamentals correspond, with the exception that the specific type of hingeshown is adapted for the support ofadjoining movable easements. Accordingly, those parts which have their equivalents in the preceding description are similarly designated, with differing reference characters only applied where necessary. Firstly it is to be observed that the modified form of hinge, herein comprehensively marked 23, comprises a stationary member 24, and a pair of movable members '7, 7'; the latter strictly conforming with fore explained.

the precedin explanation other than being right and left counterparts.

The stationary member 24, however, is

substantially in the form of a short-leg T; that is to say, it embodies co-planar anchorage pads 25, 25' with apertures 26 whereby itis securable through the medium of screws 11 to the window frame 1. Integral with the stationary member 24 is a short leg or apertured bracket projection 27 that affords support for the pintle adjuster screws 15 on which the movable members 7, 7 are pivoted, with interposed washers 22, as be- Particular attention is directed to the fact that the function of the hereinbef'ore described grippage overlap or clevis 12 is, in this form of my invention, relegated to an apeitured stirrup-member 28 which engages the outer washers 22, as best shown in Figs. VI and VIII.

. From the foregoing it is thought that my invention will be well understood, but I wish to'herein stress the fact that any requisite adjustment is easily effected by each pintle screw 15, and that when suificient tension is placed thereon, it exerts a pressure on the washers 22 and,'in turn, on the bearing portions of the associated stationary member 6 or 24. This degree of tension, obviously, determines the amount of pressure, and consequently the degree of friction or resistance which the stationary parts 6 or 24 ofierto the engaging surfaces of the co-operative moving member 7, 7'.

Furthermore, it will be understood that hinges of the typified character embodying a clevis 12 or stirrups 28 and combination of unlike metals or materials require no oiling or lubrication; that they do not in: volve sill hardware on the window frames which interfere with a clear unobstructed view through the sash or casement panes; and, finally that they are designed to ensure an even distribution of friction irrespective of the angular degree of sash-or the likeopening relative to the frame therefor.
