" l Drewersburg, in the countyof Franklin and all the figures.

Stop-Fasteners; and I do declare that the State of Indiana,have invented certain new and useful Improvements in Window-Sash 5 following is a full, clear, and exact descriptlon of the same, reference being had to the 1 annexed drawings, making 1a` part of this y specication, in which-- framewith the sashinserted. Fig. Bis de`l J tachedyiew` of asash elevationshowing the stop fastener-sand `the arrangement for :operatingthe Same. Fig. 3 is a top View of f `the frame with the cappiece removed and the-sash inserted, showing the manner in `whichthe jambs` areconstructed and also 1 y the manner in which the stopl fasteners act against the side of the groove of the jamb.

" Fig. 4 is a detached sideview of the stop i v fastener. Fig. 5 is an ed e view of the same.

Similar characters re er to like parts in The nature of ;my invention, consists in a new andimproved mode `of constructing stop fasteners for window sash.

My invention further consists of constructing the jambs, in such amanner as to admit of the lower or front sash,"bein`g` made `wider than the upper or back one. This is accomplished by an offset in each jamb, said "offset extendingfromtheupper to the' lower extremity of the frame.

`The obj ect of constructing the jambs, with? offsets, and consequently requiring theylower sash t be wider than the upper, `is to enable me (by the application of the stop fastener injconjunction with the offset jamb) to take or put either of the sash square from or in i the frame, without the inconvenienceof rei moving any part of thesame, also to raise i or lower either of them atpleasure and se 3 cure them in the desiredposition, as will be hereinafter described. And further, by

` i forming an offset on thejambs, and making f1 described.

theflower sashf wider than `the upper, a `strap or shoulder isformed, against which the lower sash is pressed bythe Stop fastener, answering every purpose `of the stop strap l generally placed between the sash. By this arrangement it will beseen that sash may be"` made to t closelybetWeen the jambs,`and` yet be put in and `taken out `with perfect ease and facility, as will be hereinafter ITo enable others skilled in the arts to B) represents the lower and (B) the M upper sash. i

(C) are the stop fasteners which are made in a curved form, as seen in Fig. 5, for a v purpose thatwill be hereinafter `described. y f 1 (c) are metallic rings connected with the Y Figure lis aside elevation of a window stop fasteners by means of a wire, as clearly A is to press the fasteners against the `groove in the side of the jamb.

(f) are offsets one of which is formed in each jamb, as clearly shown in Figs. l and 3. (e) are grooves into which the fasteners take and by pressing against the side of the same, re-act against the sash, by whichreaction two distinct offices are performed; 1st, they hold the sash in thev frame thus performing the oice of a fastener and; 2nd, they ress the sash rmly against the edge of o set (f) for the purpose of making the joint between the sash and frame air-tight or nearly so, and also to prevent the window from being shaken by the wind.

from the use of my stop fasteners it is indispensably necessary to form an offset in the jamb as at (f) for without said offset it would be necessary to use the strap which is ordinarily placed between the sash for the purpose of preventing the bottom of the lower sash from working outward. Now if we use a strap between the sash it would y prevent the accomplishment of the object for which my fastener is intended, from the fact that the back sash could not be taken out unless the stop was previously removed. Now'` it will be seen by examining Fig. 3 that offset (f) ywill perform `three distinct offices. `lst,.it forms a jamb for the upper sash. 2nd, it substantially forms a stop strapv (i. e. when used incombination with the stop fastener) to hold the upper sash in itsproper place; and 3d,.it forms a shoulder against which the lower sash is pressed and kept in its proper place. It is therefore by the advantages gained by the use of the ofi;- set jambs (as above set forth) in, combination with the stop fasteners, that I am enabled to take either or both of the sash from the frame without previously detaching any part of the fixtures of the same.

The object of making the stop fastener in a curved form is as follows: It will readily be seen that Ythere is a great advantage gained by having the fasteners press against the side instead of the bottom of the groove (e) for by pressing against the side, the sash is kept constant pressed back against the edge of the offsets (if) thereby rendering the joint air-tight or nearly so. Now it will be seen that this side pressure could not be obtained without making the stop fastener in a curved form for it would be impossible to operate a straight fastener diagonally through the side of the sash against the side of the groove (e), from the fact that the thickness of the ordinary sash will not admit of such an arrangement.

Operation: To raise or lower the window we have only to slack the pressure of the fasteners against the side of groove (e) by a moderate pull on rings (c). This relieves the sash so that it can be moved up or down with perfect ease. To take the sash out from the frame it is necessary to draw the fasteners entirely within the side of the sash, so that they will not come in contact with the side of the jamb, then take the sash straight forward out of the frame.

I do not claim operating the stop fasteners by means of spiral springs, as the same function might be performed either by elliptic springs or weights and pulleys, but

What I do claim as my invention and de u sire to secure by Letters Patent isl. The curved form of the stop fasteners constructed in the manner and for the purpose as herein described.

2. I claim the offset in combination with the fasteners for accomplishment of the object as herein described.

In testimony whereof I have signed my name before two subscribing witnesses.

DAVID RUSSELL.
