WINDOW.

Appli-cation filed. .Tune 25, 1925. Serial No. 39,489.

To all whom @'25 may concern:

Be it lnown that I, HENRY NnvisoN, a citizen of the United States, residing at Lincoln Park, in the county of W'ayne and State of Michigain'have invented certain new and useful Improvements in lVindows, of which the following is a specification.'

rlhis invention relates to certain novel and useful improvements in window construction, and is designed particularly for use with sash adapted to slide vertically in their frames. p

The objects of my invention are 'as follows: first, to provide for the Vswinging of the sashesoto an approximately horizontal position within the room for cleaning; second, to provide a swinging window havingV a weather tight joint between the sash and its frame; third, to provide a swinging sash having non-rattling features; fourth, to provide a swinging window that .is capable of being economically installed in the ordinary type of sash and frame with its sash cord and weights; andV- fifth, to provide for eX- ceptionally easy lsliding' operation by reduc, ing the friction of the sash within its frame. l attain these objects bythe mechanism illustrated in the accompanying drawing, in which Y f Figure l is a vertical section of the window and sash in a'plane parallel to and at the's'urfaceV ofthe glass in the lower sash; Fig. 2, a horizontal section on the line 2 2, Fig. 2; Fig. 3, a horizontal section on the line 3 3, 1,; Fig. 4, a horizontal section on the line 4 4, Fig. 1; Fig. 5, a vertical section cn the line 5 5, Fig. 4; Fig. 6, a vertical section on line 6 6, Fig. 1; Fig. 7, a vertical section on line 7 7, Fig. 6; Fig. 8, a vertical section on line 8 8, Figfl,

showing both sashes swung to a cleaning posit-ion; Fig. 9, a vertical section von line 9 9, Fig. 1; Fig. 10, a side view of the upper ends of the metal guides 1n the window casing; and Fig. 11, a vertical section on Yline 11 11, Fig. 9.

Similar numerals refer to" similar Vpar-ts throughout the several views.

YrEhe window sash show-n' in the drawings is of the ordinary type, having ran upper cross member 1. a lower cross member Y2. a vertical stile 3,v and a glass `pane il. Metal shells 5, are'fastened by screws Gpinthe vertical grooves of the Wi'ndowcasing 7. The

- metal-shell 5 .is formed --with van open sfide toward the stile 3, the open side acting as a groove in which slides the metal shell 9. Metal shell 9 is formed with a flange 10 against which the stile 3 contacts when the window is swung to a closed position.

Teather strip 11 is formed from metal intoa convex shape as shown in Fig. 3 and is fastened by folding the edge 12 around the inside vedge of the metal shell 9. The corner 13 of the nieta-l shell 5 is formed with a slight depression which 4allows ythe rounded edge 12 of the weather strip 11 to assemble Esnugly as shown. vThe rounded `edge 12 allows the window to be easily swung from an open yto a closed position 'without damaging the corner of the stile 3. The weather strip 1.1 and metal shell 9 extend for the full height `of each stile and slide with the stile asl the sash is operated up and down within the groove of metal shell 5. A hook 14 is formed by punching a hole in the wall of the metal shell 9 and pressing a portion of the metal into the shape as shown in Fig. 11. Sash cord 15 is looped around the hook 1li and the end of the sash cord is retained by clip 16. Thus the sliding of the window sash together with the metal shell 9 and weather strip 11 is facilitated by the or- 'dinary sash cord 15, operating over pulleys 17, they sash cord 15 being attached to the usual sash cord weight which operates within the casing and which is not shown in the drawings.' Also the sliding of the window sash is further facilitated by the action of the roller pins 18 which lit within holes in the walls of the sliding metal shell 9 and bear against the inside of the fixed metal shell 5. The roller pins 18 are rounded at their ends and are retained from end motion by thel end walls of the metal shell 5.

In a groove at the bottom of the lower cross'memher 2, of each sash is fastened a bracket 19 having a `cam 20, which extends through a hole 2 1 in weather strip 11 into the groove formed by the walls of sliding shell 9. When the window sash is in a vertical and sliding position, the cam 2O has its shortest length lying in a horizontal plane and its longest lengthin a vertical plane as shown in Fig. 6. In' this position vthe shortest lengthgiit's, without binding, between the walls Vof the shell T9. TNlien the window is swunginto a reclining position for cleaning,

'as shown in Fig. 8, 'the 'longest length of the 'cam '20 'moves tlfirough an angle of approxi- Cil lill

matel)Y 900 and then lies in a horizontal plane. The longest length of the cani 2O is made slightly greater than the distance between the walls of the metal shell l) and thus binds or wedges itself into a lixed position which in turn locks the window in position for cleaning. The bracket 19 is further ex tended into a round pivot Q2 which turns within the bearing block Q8, the bearing block 223 being suitablyv fastened to the inner walls of the shell t). The pivot Q2 titting within the bearing' block thus forms a swivelline connection between the lower cross member 2 of the window sash and the sliding metal shell 9. It is to be noted that the pivot 22 is ccceutricaltv located toward the inside of the sliding sash. This allows the bottom ot each sash to swing' clear of the liange ltl, when the sashes are swung to a cleaning position as shown in Fig. S.

At the top of the upper cross member l of each sash is fastened a loch plate 2l which has a tongue Q5 which lits between the walls, of the sliding` metal shell il. "he tongue has a slot 26 through which operates the cord l5. yl`he tongue' not only operates as a lock to keep the window sash in a vertical sliding position but also forms a weather protection for the inside of the sliding' metal shell 9. The lock plate 2l is preferably made ot pressed metal with a linger hole 2T and elongated screw holes 28 which permit. ot sliding' the lock plate 2l with itstongue out ot engagement with the sliding' metal shell Q. thus allowing` the window to swivel inward to a cleaning' position.

lt is to be noted that the fixed metal shells extend for the full length of the ca. ing and are made with a recess 29 which tits around the pullelvs 1.7. Also the upper ends of the sliding metal shells 9 are made with a slot bl which allows the metal shells 9 together' with its sash to slide up to the top of the easing without interfering` with the pulleys 1T. In Fig. l0, the sliding metal shell 9 is shown at the upper end of its travel.

To allow the upper sash to be swung` inwardlv over the lower sash, as shown in Figi'. S. it is necessary to malte the upper sash slightly.' narrower than its mating lower one. 'this necessitates moving the fixed metal shell .3. lor the outer sash, in toward the center ot the window sash to accommodate the narrower upper sash. This is economicallhv acconn'ilished bv using a wood ller strip 30, as shown in 2, this in turn allowing the use of the same sized slidingl shell 9 and lixed shell 5 for each sash.

To operate te a cleaning position, operator slides both sashcs to the bottom of the casing, slides the lock plate 2l out of engagement with the sliding metal shell 9 and then the sash will swivel in bearing block 23 until itv occupies a position as shown in Fig'. S, when it will be locked by the Cain. 2O within. the sliding shell tl, from further vertical movement.
