IMPROVED SASH-IASTENER.

The Schedule ref erred to in these Letters Patent and making part of the sani@ `may be distinguished from others of a similar class,

together with such parts as I claim and desire to secure by Letters Patent.

My invention relates tothe sashes and frames of windows, and consists in certain modications in the details of the same, whereby the sashes may be securely locked when closed, in such a manner as to resist extraneous pressure,4 or hold in position when raised, lowered, or occupying any intermediate situation, 'by means of springs attached to the same, and so arranged that the said sashes'may be removed from the window or frame wit-l1 facility. Y

In the accompanying plate of drawings, which illustrates my invention and forms a part of the specification thereof-V Figure l is a front elevation of the window-sash and frame.

Figure 2 is a side elevation of the frame, showing the guides upon which the sashes run;

Figure 3 is a view of the lower sash; and

Figure 4 is a view of the upper sash and the springs attached thereto.

Upon the sides A of the frame are secured the guides B, consisting of wooden strips screwed or bolted to the said sides.

The said guides are of such a size as to t the grooves D of the sashes E, and of a length a little less than that of the groove D, in order to allow the said sashes to be removed with facility.

XVithin the groove D of upper sash E is secured the spring F.

A similar spring, l", is also attached to the side G ofthesaid upper sash, slots being cut in the said sash of a suitable sizc for the reception of the said springs.

'lhe operation of my invention is as follows:

Ihc grooves D of the sashcs having been fitted over the guides B, the upper sash is raised and the lower sash caused to descend until the window is closed, and the sashcs firmly locked in position hy the spring F', which catches over the top of the lo'wcr sash.

lhe upper sash is held in any intermediate position bythe elastic pressure of the springs I" and F', and the sashes are respectively or conjoint-ly held in any position by means of the pressure and the leverage `thereby caused. v

IVlien it is desirable to remove the upper sash from the frame, the same may be displaced with the great- 'est acility, by lowering it'until the grooves D are clear of the guides B.

'lhe lower sash may be removed in a manner analogons.

Thus, by the construction and arrangement of the partsherein described, the sashes are `not only heldin position without the use of any one of the many appliances which have hitherto been used for that purpose, but they may be removed with the greatest ease from the frame, by merely raising 0r lowering the sash.

Having thus described my invention, I will indicate what I claim and desire to secure by Letters Patentin the followingclause, to wit:

The spring F', so arranged on the face of the sash as to act as a friction-support when the sashes are partially raised or lowered, and absolute fastening for both sashes when closed.
