IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 178,990, dated J une20, 1876; application filed April 12, 1876.

To all whom it may concern:

Be it known that I, STEPHEN BROWN, of Washington, in the District of Columbia, have invented a certain new and Improved Combination Sash-Lock, of which the following is a specification The object of my invention is to provide a sash-lock which will fasten the lower sash down, and will-lock the upper sash either in closed position, or in any position in which it may be adjusted for ventilation, both of the sashes being locked by a single fastening.

To this end my invention consists in constructing a lock or button with separate projections, which, when the said button is attached, by a pivot-screw, to the lower sash, engage with separate exposed notches in the upper sash, and in the parting-strip, respectively, as hereinafter more fully described and definitely claimed.

In the accompanying drawing, Figure 1 is an interior elevation of a window with my in vention applied. Fig. 2 is a vertical section on the line 2 2, Fig. 1. Fig. 3 is a horizontal section on the line 3 3. Fig. 4 is a perspective view of a button of modified form adapted for application at either the right or left side of the sash.

A A A represent various parts of a windowframe. B G are, respectively, the upper and lower sash. D Dare the parting-strips. E E are the guide-strips or beads toretain the lower sash. F is my improved lock or button, which is, preferably, formed in the anchor shape represented in Fig. 5, with two laterally-projectin g arms, ff, to adapt it for application to either side of the window. The button is secured to the top of the lower sash, as shown, by a screw applied in thepivot-hole g, and is provided with a knob, h, for moving it in either direction. It is formed witha projectin g end, i, to engage in either of the notches b b b in the upper sash, so as to lock the said sash either in its uppermost and closed position, as illustrated in the drawings, or in any partially-opened position to which it may be adjusted for the purpose of ventilation. The notches b, &c.,are preferably formed in plates let into the sash for the purpose of receiving the button. The arm ff of the button engages at the same time in a notch, 0, in the parting-strip, for the purpose of locking the lower sash, and thereby holding both immovably in place.

either side, for the reception of the buttonarm ff, so-tl1at the latter may be placed on either side of the window, as convenience may dictate, corresponding notches 1) b being, of course, formed in the face of the upper sash on the same side of the window. For the purpose of supporting the lower sash in any position desired, if the said sash be not hung on weighted cords, I employ a catch, J, of any usual or suitable construction, pivoted to the guide-strip E, and engaging with a notch or plate, K, on the face of the sash,-or

The notch b may be piofiected by a metal plate; also, if desired, a simple. 'notch may be formed in the parting-strip on
