SPECIFICATION forming part of Letters Patent No. 583,976, dated June 8, 1897.

Application filed December 17, 1895. Serial No; 572,387. (No model-l To all, whom it may concerns Be it known that I, JOSEPH B. ,BRQOME, a citizen of the United States, residing atUtica, in the county of Oneida and State of New York, have invented an Improvement in With (low-Sashes, of which the following is a speci-' fication. v I i 1 indow-sashes have heeupivoted at their opposite 'edges to sash-strips that slide in the window frame or casing, and the adjacent surfaces have been grooved for the reception of metal strips haviu g diagonal slots by which such metal strips have been forced outwardly to connect the sash and sash-strips or drawn inwardly into the sash to allow such sash to be swung upon its pivots.

The present invention is for facilitating the construction of the parts and to allow each metal strip to be drawn inwardly and retained with facility or he forced directly outwardly into the groove of-the sashstrip and held automatically so as to prevent the parts becoming misplaced or inoperative when the sashes are raisedo'r lowered; and the present invention consists in the peculiar construction and com' bination'of devices hereinafter set forth and claimed. I

In the drawings, Figure I is an elevation representing portions of a sash, partially in section toshow the pivots and the sash-strips and the connecting devices. Fig. 2 is a plan 'view in section,- representing the upper and lower sashes at one side of the WlIld0\i'-fltl1l6.

The window-frame A is made in any usual manner, and the parting-stri p is represented at K and the stop-head at 3. The sash 13 is adapted to reccive t-he glass as usual, and it is sufficiently narrow'to be swung upon its pivots between the stop-hen is of the windowframe, and the sash-strips C are introduced into the runways of-the window-frame at the edges of the sashes, and the pivots I) are midway, or nearly so, between the top and bottom edges of the window-sash, so that the sash may he swung upon such pivots toiopen the same and give access to the outer surface of the'glass for cleaning, or the sash may be swung in this manner in opening the window to any desired extent.

I find it advantageous to malcc each pivot with a plate 4, from which a pivot-pin 5 projects, and this plate is let into the edge of the sash, and behind the plateis a stud 6, passing into a hole in the sash, and by making the pin 5 smaller in diameter than the stud '5 6 51. hole can be bored through the sash-strip (l'and into the edge of the sash, the size of the hole corresponding to the size of the stud 6, so that the stud can be driven firmly into the hole in the sash, and thereby the pivot will be strengthened and not liable to work loose, and a short tube 7, of brass or other suitable material, can be forced tightly into the hole in the sasl1-strip, so that the pivotpin 5 will turn freely in such tube and prevent the pivot embedding itself into the wood or enlarging the hole in the sash-strip.

In each edge of the sash a saw-cut is made ofadepth sufficient to receive entirely into it the metal strip F, and a similar saW-cutis made in the outer face of each sash-strip and corresponding in position to the saw-cut in the sasli,.but not as deep, so that the metal strip 1 can be contained in the saw-cut in the sash when the sash is being swung on its piv-- 7 5 ots, and it can he moved outwardly, so as to enter the saw-cut in the sash-strip when the. window is swung up into position. In this metal strip, preferably toward the ends, horizontal or transverse slots 8 are made that re- So ceive through them pins or screws 9, and the lcngtlrof the slots 8 and the positions of the pins or screws 9 are such that the metal strip can freely be moved ,huclc into the saw-cutin the sash or pressed outwardly into the sawcut intho sasl1stri p, and the pins or screws passing-through the slots hold the metal strips in position, and I make use of helical springs G, introduced into holes bored into the sash and behind the metal strips and preferably go toward the ends ot' such strips for forcing the metal strips outwardly into the sash-strips when the parts are not otherwise acted upon.

Near the middle of each metal strip F is a retracting-handle II, forked at one end and connected to the metal striphy across or pivot pin, and this retracting-handle is advantageously cylindrical, so as to pass freely through a hole bored in the sash and approxiinatcly near the pivot-pins, and this retract- IOO ing-handlo has a notch 10, engaging a plate 11 or similar stop when the handle .lI has 'been drawn back and with it the metal strip, the springs G being compressed inthe operation.

From the foregoing it will be understood that when the sash is to be swung upon its pivots thehandle If is drawn inwardly and the metal strip F drawn-out of the sash-strip entirclyinto the saw-cut in the sash, and the retracting-handle is then caught with its notch upon the plate 1l,.and the same opv'eration is performed at each edge of the sash, and the sash is then free to be swung upon its pivots for opening, the sash and giving" access to the outer side of the glass for clean ing or otherwise, and when the sash has been swung up again into its position the retracting-handles ii are moved sufficiently to lib.- crate them from the plate 11 and allow the springs G to project the metal strips into the saw-euts in the sash-strips, and by so doing the sash, will be prevented from swinging on its pivots, and the joints between the sashstrips and the sash will be closed by the metal strips passing across into the saw-cuts in the sash-strips.

i find it advantageous to make the metal strips F of a shorter length than the height of the sash, so that the ends of the saw-cuts may be closed by wooden blocks, putty, or oth r suitable materiahasillustrated in Fig. 1.

The top rail of the lower sashaud the bottom rail of the upper sash are usually beveled upon their adjacent surfaces and form the meetings-ails of the sash,- and the end portions of these meeting-rails are adjacent to the. parting-strips K of the window-fra1ne, and it is often difficult to make. the sashes tight where .the meeting-rails of the rashes come against the surfaces of the parting-- strips, because the portions of the meetingrails of the sashes are apt to rub upon the surfaces of the parting-strips K as the sashes are raised or lowered, and when the necessary play. is provided there is almost always an opening at the ends of themecting-rails of the sashes adjacent to the surfaces of the partingstrips. To avoid this dilliculty, I make the parting-strips K wider, as shown at 12, and closely adjacent to the meeting-rails of the sashes, so that when the sashes-arc closed upwardly and downwardly the ends ot the meeting-rails come close to the surfaces of the parting-strips at 12, where they are wider, but the other portions of the partingstrips being narrower do not in any way come in contact with the ends of the meeting-rails of the sashes when such sashes are either being raised or lowered. IIence these central rojections at 12 on the parting-strips make in to'such sa\v'-cu is and having cross-mortiscs' in such strips, pins passing through the mor Uses and springs to press such strips outward from the sash into the saw-cuts in the saslrstrips, a retracling-handle pivoted to each strip and passing through the sash for drawing back the metal strips into the sash, substantially as set forth.

2. The combination with the sash and sasln strips having; longitudinal saw-cuts in their adjacent surfaces, of metal strips introduced into such saw-cuts and having cross-mortises .in such strips, pins passing through the mortises and springs to press such strips outward:

from the sash into the saw-cuts in the sashstrips, a retracting-handle pivoted to each strip and passing through the sash for drawing back th -T metal strips into the sash, pivots for connecting the sash tofthe sashstrips and upon which pivots the sash can be swung when the metal strips are withdrawn, substantialiy as set forth.

:5. The cmnhination with the sash and sashstrips havinglongitiulinal saw-cuts in their adjacent surfaces, of metal strips introduced into such saw-cu ts and having cross-mortiscs in such strips, pins passing through the Inortises and springs to press such strips outward from the sash into the saw-cuts in the sashstrips, a retractinghandle pivoted to each strip and passing through the sash for (irate ing back the metal strips into the sash, there being a latch upon the retracting-haildie and a plate upon the sash for engaging the latch, substa'nt-ially as set forth.

4. The combination with the upper and lower sashes, of intermediate partingstrips on the wiiulo\\-'-fraine, the edges of which parling-stri ps project from the wimlmr-fraine a greater distance adjacent to the meet-ingrails of the sash when the sashes are closed than at the other portions so to set closely against the meeting-rails when the sashes closed and allow freedom of movement when the sashes are being opened, substantially set forth.
