JOAH BROGDEN, OF MELBOSE PARK, PENNSYLVANIA, ASSIGNOR TO DAVID L'UPTONS SONS COMPANY, OF PHILADELPHIA, 'PENNSYLVANIA, CORPORATION OF I'ENN SYLVANIA HINGE Application filed. December 28, 1926. Serial No. 157,446.

This invention relates to hinges, and more particularly, to hinges useful for casement windows and the like. As ordinarily constructed, such hinges comprise two bracket arm components which are inter-pivoted beyond the plane of the casement window so that as the latter is opened, the near edge of its sash swings away from the corresponding jamb rail, thereby rendering opposite sides of the glass readily accessible for convenience in cleaning.

My invention is directed toward rendering hinges of the type referred to capable, through adjustable frictional resistance, of

maintaining the casement sashesin any desired position of opening against the possibility of being moved to and fro or slammed under the action of the wind pressure.

The foregoing desideratum I seek to se cure by means, in the nature of an attachment which is conducive to very economical manufacture and easy application to standard types of casement hinges, without requiring any changes whatever in their construction or special tools for the purpose.

With reference to the drawings, Fig. I

shows a horizontal section through a typical casement window equipped with hinges conveniently embodying my invention.

Fig.II is a perspective view of one of the hinges on a larger scale.

Fig. III shows a fragmentary sectional view throughthe hinge'pivotwith the component hinge arms opened out into aligned relation; and, 1

Figs. IV and V are detail perspective views of certain parts of my novel friction creating attachment.

The casement window structure chosen for convenience of illustration in the present connection, comprises a metallic jamb frame whereof the perimetric rails are formed, as shown in Fig. I, from rolled bar stock of Z-shaped cross section. The sash frame 11 is constructed from identical bar stock, and

closes against the jamb frame 10, in the manner illustrated, with its face flange 13 overlapping the corresponding face flange 12 of the latter frame. I

The sash hinge comprehensively designated 15, embodies components 16, 17 which are in the form of longitudinally-slotted bracket arms with integrally formed anchorage pads 18, 19, adapted to be secured respectively to the flanges 12, 13 of the frames 10, 11, by appro riate fastening means such as screws 20. he outer ends of the bracket arms 16, 17 are joined by a pivot pintle 21 so that as the sash is swung outward, in the direction of the arrow in Fig. I, the near edge moves away from the correspondingjamb rail of the frame 10 thereby rendering opposite sides of the glass pane 22 readily accessible for purposes of cleaning. From Fig.1IIit will be observed that the pintle 21 is in the form of a screw bolt with a polygonal head 23, the major portion of thepintle shank passing free through a hushed aperture 24: in a hinge component l7,'and the lower threaded end taking into the component 16. g

I In converting such a hinge to the purposes ofmy invention, I employ a novel frictioncreating attachment means which includes a number of friction members such as shown at 25 in Fig. IV, and an ordinary splitspring washer of the characterexemplified at 26 in Fig. V. The friction members 25 may be conveniently struck from sheet material with rounded ends apertured for passage of the hingepintle 21, and laterally turned parallel side edge flanges 27 for capacity to fit over the hinge components 16,17 with restraint against independent movement relative there to. These members 25 I preferably form from unlike metalsfor example, brass and steel-ecapable, when maintained in pressure contact, of restraining free sliding movement one over the other without undergoing appreciable wear under long periods of usage. In equipping the hinge, two of the friction members 25, one 25 of brass and the other 25 of steel, are interposed between the hinge components 16, 17 after the manner shown in Fig. III. The spring washer 26 ispreferablyof steel and placed, with plain facing washers 28-also of steelabove and below it, beneath the head 23 of the hinge pintle21, while another friction member 25*, of brass, is positioned between the washer assemblage and, the contiguous face of the hinge component 17. Obviously, by tightening-up of the screw pintle 21 to different extents, the contact pressure between the friction members 25, 25 intervening the hinge components 16, 17 may be variedwith incidental cooperation of the spring washer 26to increase or decrease resistance to free hinge movement as required. and thereby hold the easement sash 11 in any desired position of opening against the possibility of displacement from such position under wind pressure. A clamp or jamb nut 29 engaging the protruding lower end of the pintle 21 serves to lock said pintle in adjusted positions. Inthis connection: it is to be particularly noted that by virtue of the unlike materials from which they are made, the lower facing washer 28 and the member 25 with which it contacts also cooperate after the manner of friction units and therefore contribute to the restraining effect against free movement of the casement sash 11.

From the foregoing it will be apparent that my novel attachment is extremely simple, easily applied to the hinges, and adjustable with the aid of an ordinary screw driver and a wrench or pair of pliers.

Having thus described my invention, I claim:

1. In a hinge of the character described comprising two complemental hinge components, the combination of interposed friction members of unlike material with apertured ends for passage of the hinge pintle respectively associated with said components and individually restrained from movement relative to them by integral parallel side flanges, and a pivot screw pintle passing free through one of the components and taking into the other with capacity for adjustment to vary the contact pressure between said friction members and thereby increase or decrease resistance to hinge movement.

2. In a hinge of the character described comprising two complemental hinge components, the combination of a pivot screw pintle passing free through one of the components and threadedly-engaging into the other, opposing friction members of unlike materials with apertured portions for passage ofthe pivot pintle interposed between the hinge components at the pivot region, said friction meml ers also embodying channel-section port-ions engaging over the hinge components, and a split spring washer beneath the head of the screw pintle cooperating incidental to adjustment of the latter to varythe contact pressure between the friction members aforesaid in increasing or decreasing the resistance to hinge movement.

3: A; friction creating attacliment for hinges compris-ingopposing friction membersadapted to be interposed between the inter-pivoted complemental components of the hinge, said friction members being fashioned from unlike sheet metal with eyeportions for passage of the hinge pintle and integral channel-section extensions to engage over and move respectively with the hinge components and to cooperate in resisting hinge movement to various degrees determinable by adjustment of a pivot pintle screw passing free through one of the hinge components and thrcadedly-cngaging into the other, and a split spring washer for interposition beneath the head of the screw pintle toassist in maintaining the friction in accord ance with adjustments made as aforesaid.

In testimony whereof. I have hereunto signed my name at Philadelphia, Pennsylvania, this-22nd day of December, 1926.

JOAH BROGDEN.
