Be it known that IYWALTER GORDON LAW- RENGE, asubject of the Kingflof Great Brit-' ain, and a resident of .214Worsley road, Winton,in the county of Lancasten'England, have invented certain newand useful.

Improvements in Windows; and I do hereby declare that the following is a full; clear; and exact description of the same.

The invention relates to improvements in windows, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novelform of self adjusting hinge support for casement windows.

The objects of the invention are to be able to get at all parts of the window for cleaning purposes no matter which way the sash is swung, to devise a simple and efiicient means of supporting the sashes in casement windows which will avoid all clogging and jamming of the sash at the hinged portion as the frame can readily be cleared of all obstruction, and generally to provide a simple, cheap and durable window.

In the drawings Figure 1 is a perspective view of the pivotal support or hinged member at the lower end of the sash showing the other hinge member attached to the frame. Fig. 2 is a plan view of the arrangement shown in Fig. 1 with a partly open'position of the sash indicated by dotted lines. Fig. 3

' is an enlarged sectional detail of a hinge pin 35 and slotted plate. Fig. 4 is a sectional view of another hinge pin and the slotted plate.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings 1 is a vertical rail of the window sash.

2 is a horizontal sash rail.

3 is a window frame formed of metal or wood as desired, though in the accompanying drawings a metal frame is shown, also a metal sash.

4 is a hinge member rigidly secured to the horizontals of the frame 3 and having a plate surface 5 parallel with the said horizontals and a parallel slot 6 extending the greater part of its length and a lug 7 extending outwardly from one end of said plate portion 5 in an oblique direction and formed in opposing curves 8 and 9 with a recessed interior flanged at the sides by the flanges 10and 11, forming the under cuts 13. The under cuts 13 are formed by a cut into the longitudinal .undercorners of the lug .7, said lug having-in the, bed of the recess the holes 14 withthe bevel edges 15.

16 s a bracket. formed with the boss. 17,

tending fromsaid boss into the slot 6, said plate extensions 18 being rigidly secured to the vertical rail l andthe horizontal rail 2 at the corner thereof. v

20 is a bracket flanged at itsinner end 21 and rigidly secured to the horizontal rail 2 adjacent to a 'plate extension 18, said bracket 20 extending'outwardly and carrying at the outer end thereof the pin casing 22, said pin casing having a shoulder 23 in the interior thereof and at its lower end a flange 24 extending into the under cuts 13. I.

25 is a pin having at its lower end the round head 26 and extending upwardly into and through said pin casing2 27 is a spiral spring encircling the pin 25 between the flat inner side of the round head 26 and the shoulder 23, thereby constantly exerting a downwardpressure on the head 26 so that the said head will engage in one or other of the holes 14. The hinge members 4 and 20 are'seoured in pairs to the corners of the window frame and to the sash as usual.
