IMPROVEMENT IN SSH-BALANCES.

Specification forming part of Letters Patent No. 170,240. dated November 23, 1875; application led June 26, 1875.

To all whom it may concern:

Be it known that I, HENRY CUTTING, of the city of Budalo, in the county of Erie and State ot' N ew York, have invented certain new and useful Improvements in Sash-Holders, which improvements are fully set forth in the following specitication, reference being had to the accompanying drawings.

'lhis invention relates to that kind of windows in which a yielding friction-strip is arranged in the casing on each side, to bear against the edges of the sash with sufficient forceto sustain it in position when raised.

My improvement consists in placing these friction-strips'loosely in grooves extending the entire length of the casing, with springs behind them, and causing their protruding por.i

tions to enter corresponding grooves in the sash, so that they will also serve the purpose of guides,on which the sash can slide'up and down, and the sash can be readily removed and again inserted by simply. pressing the friction-strips back into the grooves in the casing.

`Figure 1 is a front view ofmy invention; Fig. 2, a vertical section through the center of a window frame or casing; and Fig. 3, a trailsverse section through the Window-frame, sashframe, andthe said bars or strips.

A is the window frame or casing; B, the sash-frames. The letters G represent the bars or strips for holding the sash. They are fitted closely, but so as to move easily in the grooves D, (shown in Fig. 3, and also by dotted lines, Fig. 1,) and are forced outward from the casing by the springs E, (shown by dotted lines, in Fig. 1,) into and against lthe grooves F in the sash. This affords an even, smooth surface for the window to slide on. .The springs E hold it with sufficient force to prevent falling when raised at any point.

By lifting the Window sufficiently to reach and press back the bars C itmay be easily' taken out or returned.

G represents an ordinary lock or catch for holding the Window down when'required.

I am aware that friction-strips in some respects identical with mine have been for some time known; but they have never, to my knowledge, been disposed in the manner I have shown and described, which arrangement possesses the peculiar advantage ,just alluded to of affording a convenient removal ot' the sashes by simply pressing back the friction-strips without the necessity ot' drawing'nails or screWs,or of displacing any other -part of the window.

I claim as my invention- The window-casing provided With grooves D, extending its entire length, and the sash B, having corresponding grooves F, in combination with the springs E and the frictionstrips C, placed loosely in the grooves in the casing, and pressing against the bottom ot' the grooves in the sash, for which they also serve as guides, whereby the sash can be removed by pressing back the strips only, all arranged and operating substantially as and for the purpose specified.
