TIL'IING-SASH WINDOW.

Application filed April as,

My present invention relates to improvements in tilting sash windows, m object being to provide a window of t is type which shall be thoroughly practical in all respects to build, install and operate, and which will have the hereinafter set forth other advantages.

In the drawings, which show the embodiment I at present prefer of my improvements, Fi 1 is an elevational view of a tilting sas window construction within my invention as seen from the inside, i. e. as if from within the building, the two sash being shown shut or closed; Fig. 2 is the same except thatv the'view is from the outside of the building; Fig. 3 is a vertical sectional view, partly in elevation, on a larger scale through the same, the building stone-work at the top and bottom of the window bein also shown in vertical section, said figure eing economized as to height at the two places indicated by the broken lines, and the sash being shown shut; Fig. 4 is a horizontal and sectional view, partly in plan, on the line 4-4 in Fig. 3, the stone-work of the building at the sides of the. window being also shown in horizontal section, said drawing being economized as to width at the two places in-' dicated by the broken lines; Fig. 5 is a View" like Fig. 4 except that it is on the line 5--5 in Fig. 3, namely, is on a horizontal section through part of the lower sash and through one side only of the window frame; Fig. 6 is like part of the right side of Fig. 4 except'that it shows certain removable panels detached; Fig. 7 is a verticalsection; partly in elevation, on the line 77 in Fig. 4; Fig. 8 is like Fig. 3 except that the sash are both shown tilted inwardly into a horizontal position as for cleaning them; Figs. 9 and 10 are horizontal sectional views, partly in plan, respectively on the lines 9-9 and 10-10 in Fig. 8; Fig. 11 is a vertical sectional view, partly in elevation, on the line 11-11 in Fig. 4 looking in the direction of the arrows; Figs. 12 and 13 are broken away views in elevation of the aforesaid panels;

Fig. 14 is a vertical sectional, partly elevational, view through one of the sash weight compartments on the line 14-14 in Fig. 11 looking in the direction of the arrows; Figs. 15 to 20 inclusive are views similar to Fig. 8 on a smaller scale, showing some further manipulations and relative positions of the sash possible with my construction.

I will now describe my improvements by 1928. Serial No. 635,250.

way of theparti'cularly preferred embodiment thereof shown in the drawings but without limiting myself thereto except as may be required by the annexed claims properly construed.

A, B and C designate respectively the top, bottom and sides of the stone or other buildng construction within which my window 1s shown mounted;

The drawings are intended to 'show a sheet metal fireproof construction of the sash, wlndow frame, etc., but I do not limit myself to these materials.

1 and 2 respectively are the upper and lower sash. The sides of the window frame severally comprise a sash weight compartment 3, together with a side section 4. These are united at the top by the headers 5 and at the bottom by the inner and

outer sills

6 and 7.

The side of each sash weight compartment 3 adjacent the sash is made up of three panels, 3*, 3 3 (Figs. 8, 4, 6 and 11, etc), the first being a fixed panel and the others being detachable at will to et at the interior of'the compartment.

gaid panels

3 and 3 are shown detached in Figs. 12 and 13. The panel 3 is attached at the top by screws to a bracket 8 secured to the underside of the top of the sash welghtcompartment; and at the bottom is attached by screws to a cross piece 9 secured to the back of the panel 3 as best shown inFigs. 3 and 11. Panel 3 is attached by screws at the top to a bracket 10 secured to the underside of the top of the sash weight compartment and at the bottom by screws to another bracket 11 secured to the bottom of said compartment (Figs. 3, 11 and 14).

Said

panels

3, 3*, 3 are laterally spaced when in position and are shaped at their side edges to provide two'guides located in each side of the window frame, namely, an inner guide 14 and an outer guide 15 (Figs. 8, 11 and 15 to 20 inclusive, etc.).

In the description and claims, the expres sions inner and outer mean towards or shown at 14 (Fig. 11, etc.), and thence terminate each in a short vertical downwardly extending portion 14 located directly under the adjacent outer guide 15, but without communicating therewith. v

The

sash

1 and 2 have respectively pins at the top and bottom projecting from their sides, the bottom pins being designated 15 and the top pins 17, the latter being the free ends of rods, designated by the same numeral, supported for free endwise movement in the upper rail of the sash, the inner ends of said rods being bent at right angles to project loosely into holes in a disk 18 (Figs. 4 and 7) fixed on the stem 19 rotatably supported in suitable bearings in said rail, said stem having an integral external head 20 on the inner side of the rail for operating said stem by partially rotating it and said disk to simultaneously retract the projecting free nds of the rods 17 against the 0 position of the springs 21 which normal y impel them outwardly to the extent indicated in said Figs. 4 and 7 until stopped by the collars 22 on said rods. The. holes 23 in the ends of the head or handle 20 are adapted to be engaged by the hook on a window pole for retracting the aforesaid rods and pins '17, particularly of the upper sash which will ordinarily'be out of reach for direct manual operation.

The lower and permanent pins 16 of the upper sash 1 are'always located in the outer guide 15; and similarly the corresponding pins 16 of the lower sash 2 are always located in the inner guide 14. The lower halves of said guides are slots so thatsaid lower pins 16 of both sash project through into the sash weight compartments 3 as best shown in Figs. 5, 9, 10 and 11, where they eachcarry a metal piece 24 (Fig. 11) loosely rotatable thereon, to which latter in turn the sash cords or chains 25 are attached, said cords passing over pulleys 26 (Fig. 11) suspended by links 27 from the top of the compartments 3, the other ends of said cords being attached to the sash weights 28 which, as usual, serve to counterbalance the weight of the respective sash.

The upper parts of the

guides

14 and 15, being the parts shown shaded in Fig. 8, have bottoms bridging across between the sides of the guides so as to constitute rooves as shown at 14 in Fig. 4, as distinguished from the slots 14 of Fig. 5. The lower portions of the guides must be slots in my construction in order that the sash weight cords can be fastened to the lower pins 16 of the sash, whereas the upper portions need not beslots in my construction but can be grooves whose closed bottoms prevent one from seeing into the. upper portion of the interior of the sash weight compartments.

To keep the sash weights separated and at the same time avoid unnecessarily obstruct- ,sin

ingaccess to the interior parts of the sash inent, located substantially parallel to the,

plane of the window opening and projecting from one wall of the-given compartment between the sash weights therein partially across to that wall of the compartment containing the guides for the sash.

The retractable upper pins 17 of the sash 1 may be located at will either in the outer guides 15 along with the lower pins 16 thereof which is the case when said sash has any of the positions of adjustment shown 1n Figs. 1, 2, 3, 4, 11, 15,16, 17 or 20; or said retractable upper pins of said sashl may be adjusted into the other or inner guides 14 as in Fig. 18; or they may be located in neither guide and merely allowed to bear against the adjacent faces of the sash weight compartments 3 as in Fig. 19, and in this instance the projecting beads 29 (Figs. 4 and 19 etc.) are specially provided for the purpose of forming lateral stops for the pins 17, preventing the sash from unintentionally or accidentally tilting and falling downwardly to a greater angle to the vertical than that shown in said Fig. 19.

Next, referring to the other sash 2, this also can be adjusted into numerous positions depending upon whether its retractable upper pins 17 are adjusted into or out of the

guides

14 and 15, and also dependent upon whether the lower pins 16 of said sash are located in the straight upper portion of the inner guides 14, or are in the inclined porare located in the same plane. In this in;

stance,.all of the pins of the sash 1 are in the outer'guides 15 as are also the upper pins 17 of sash 2, but the lower pins 16- of the latter sash are located in the vertical bottom ends 14 of the other or inner guides 14. In this position it is impossible to raise or lower either sash, norcan either sash be tilted inwardly from the outside of the building. Of course, from the inside, the handles 20 can be operated to retract the upper pins 17 of either or both sash to permit them to be tilted, raised and lowered as desired.

Fig. 8 shows still another adjustment of the sash for cleaning their outer or weather faces from within the room, wherein the downwardly into the position shown in Fig. 8 to have its weather face cleaned.

When in this position, the sash weights would pull up the outer ends of the sash were it not that I provide to prevent this, short lateral branches 14 and 15 (Figs. 8, 11 and 20) extending upwardly and outwardly respectively from the vertical lower portions of the

guides

14 and 15 adjacent the bottom thereof, into which the sash weights quite naturally pull the lower pins 16 of the sash when they are in the act of being tilted down as in Fig. 8, whereupon said endslof the sash are prevented from being lifted by the sash weights.

lVhen the sash are shut, as in Figs. 3 and 15, I provide means first, to keep out the weather at the horizontal joint or space between the two sash; second, at the space between the bottom of "the lower sash and the outer sill; and third, at the sides of both sash between same and the sides of the window frame.

Describing these in the order named, I provide a Wide extension '32, of substantially the same width as the sash, from the bottom rail of the upper sash 1, said extension having an inwardly turned lower edge32 (Figs. 3 and 8), the latter being receivable into a longitudinally extending groove 33 (Fig. 8) in the outer face of the top rail of the lower sash when both are shut.

Also, I provide a similar wide extension 34 (Figs. 3 and 8) from the bottom rail of the lower sash 2 with an inwardly turned lower edge 34, the latter being receivable into a longitudinal groove 35 (Fig. 8) in the outer sill when said sash is shut.

To keep the window weather-tight at the sides, I provide strips 36 (Figs. 3', 8, 9 and 10 etc.) projecting from the weather face of each sash along the side edges thereof, receivable, when the sash are shut, into elongated groove-like inwardly opening but out wardly closed/recesses in vertical members 38 secured to the sides'of the window frame.

, In short, I have provided by my improvements a. thoroughly practical tilting-sash windowronstruction, some of the advantages of which are'the following:

(1) Sightly appearance when the sash are shut due to their being in the same plane.

. (2) The sash when shut cannot lie opened.

from the outside, this feature being contributed to by the fact that the lower pins of the lower sash, when shut, are located in the short vertical guides 14".

(3) Either or both sash can be adjusted for ventilation, etc., to a great variety of positions as desired to suit conditions.

(4) The weather faces of the sash can be cleaned from within the room.

(5) 'The sash when closed make a weather-tight window all around, sides, bottom and top. 4

(6) The construction of the sash weight compartments with their removable panels permits of ready access to the working parts within said compartments.

What I claim is:

1. In a multiple tilting-sash window-construction, the combination of a plurality of sash having respectively pins at the top and bottom projecting from their sides, the top pins bein retractable at will; and a window frame wiiose sides are each provided with adjacent inner and outer vertically extending guides for the pins of said sash, the lower part of each inner guide inclining downwardly and outwardly and terminating un 'der the lower end of the adjacent I outer guide but without communicating therewith. v

2. In a multiple tilting-sash window-construction, the combination of a plurality'of sash having respectively pins at the top and bottom projecting from their sides, the top pins being retractable at will; and a window frame whose sides are each provided with adjacent inner and outer vertically extending guides for the pins of said sash, the lower part of each inner guide inclining downwardly and outwardly and terminating in a short vertical portion extending downwardly from said inclined part under the lower end of the adjacent outer guide but without communicating therewith.

3.-In a multiple tilting-sash windowcom struction, the combination of a plurality of sash having respectively pins at the top and bottom projecting from their sides, the top pins being retractable at will; a window frame whose sides 'are each provided with adjacent inner and outer vertically extending guides for the pins of said sash; a vertically extendin projectingbead on the side of the window frame at its front edge independent of said guides adapted to' be engaged 'by the top pins of the sash to prevent unintentional excessive down tilting thereof.
