Application filed February is, 1924. Serial No. 693,243.

The object of this invention is to provide a hinge for windows, transoms and the like,

. which may serve both as a hinge and a support for the window or transom when open. The invention is fully disclosed in the description and claim following, reference, being had to the accompanying drawing, in -which I Fig; l is a view in perspectiveillustrating a cellar window with the improved hinges attached. Fig. 2 is a sideview of the hinge,

with a fragment of sash attached. Fig, 3:

- is a front View of the same, but showing some modification in structure.

In the drawing, the numeral 5 denotes'a cellar window sash, such windows being usually hinged at the. top so as to swing inwardly and upwardly. The connnonlrneans of support for the sash when so ralsed 1s a hook and eye holding the window in the single wide open position. In deepcellars this fastening is so high as to require a step for the operator, and the use of both hands in hooking up the window. 'Hooksor'buttons arealso required for fastening the window in closed' position. The hinges ;now'

to be described are adapted to lock the window in closed position, as well as to support it atany desired open position. a

In the drawing, the numeral 6"desig'na'tes the hinge member whichis secured to the window frame 7 This comprises a 'wallplate 8 suitably provided 'with'holes 9 for fastening screws '10, and a quadrant-shaped wing 11 disposed at right angles to the wallplate, The other, member has a similar wall-plate 12, with screw-holeslB, and a lesser wing 14 also at right angles to' the base. Near the upper end this wing is pierced, as is the other member near its upper and inner 'angle, for a pivot 15, whi'ch is preferably a small bolt that may be easily removed whenit is desired to take out the window sash. The lower end of'the wing 14: is formed as a stirrup 16 to engage the curved edge of the quadrant," as shown. Holes at 17, whichare in register lwhen the window is closed, serve for the locking of the window by pins or nails18.

In the detail figures of the have shown a plurality of means for holding the window open by friction, In Fig. 2

claim 4 V In ahmge, a fixed member consisting of a drawing I this is effected by the :wedging actionof the quadrant edge in the loop of the stirrup. V

The dotted line in this figure indicates an arc of which the pivot is the center, showing thatthe pivot is setalittle off-center with respect to the curve of the wing. It is evident" that the raising of the sash will serve to wedge the parts of the hinge together, and the friction of the parts so wedged is sufficient to support the sash. As shown in. Fig. 2 this support would. be m'ainly effective when the sash is completely elevated. In Fig. 3, however, the friction applies to the hole curve of the'quadrant, and the sash is supported at any point of elevation. In thiscase the stirrup, which should be slightly elastic, is made to pinch the quadrant with F enough frictional ,effectto support'the sash.

" For this purpose the. stirrup may be pro.- v'

vided with a tension bolt 19. A corrugated edge 20 for the quadrant enhances the grip of the stirrup, but is not indispensable. as.

sufiicient tension may be obtained on a plane surfaced wing, as shown in the Othe fi u Of the drawing. v i

The hinge members are preferably formed of thick sheet steel, and for use in cellars or other damp places should besuitably protected from rust, as by galvanizing.

Having thus described my invention, I

plate adapted to be fixed to a window frame and a quadrant shaped wing outstanding from the plate at right angles thereto,'a

movable member consisting of .a plate adapted to be fixed to a sash pivoted. in the frame and an outstanding quadrant shapedi wing disposed at right angles to the plate thereof, the second wing being pivoted at its axis to the axis of thefirst wing to be off center thereof, a U-shaped stirrup fixed to the edge of the second wing and straddling the edge of the first wing so that its free end frictionally' engages therewith, a bolt extending through'the sides of the stirrup to adjust the frictional engagement of the free end of the stirrup with the edge of the first wing.

In testimony whereof I aflix my signature.
