19 Claims.

This invention relates to a new and useful improvement in window construction and relates more particularly to a double hung sash type of window construction wherein the sashes are pivoted and adapted for rotative movement on a horizontal axis and are also adapted for vertical sliding movement as in the conventional type of sash construction.

One of the objects of the invention is to provide a window construction in which the sashes may be opened by vertical movement as well as by pivotal movement, thus enabling the dwelling or olfice in which the windows are placed to secure maximum ventilation when desired.

Another object of the invention is to provide a window in which the sashes have vertical sliding as well as pivotal movement and wherein the pivot members are interchangeable and may be placed near the top, bottom or in the center of the sash, the change being accomplished quickly and with little eifort. Thus, in the summer time when screens are on the windows the pivots may be placed at the upper portion of the sash, en-

abling the sash to be projected rather than swung on a central pivot.

Another object of the invention is to provide a window construction of the type above referred to which will permit the outer surface of the glass to be quickly swung inwards, thus enabling it to 0 be washed from the inside, thereby entirely eliminating the. dangers incidental to outside window washing, eliminating the high insurance costs on professional window washers in tall buildings and, as well, encouraging the more frequent cleaning 5 of windows in our smoke-ridden cities.

A further object of the invention is the provision of a window sashconstruction of this type which will provide Weatherstripping means which make the sash rain and wind proof with tight 4o closures at all joints.

The inventionalso has for an object the provision of a novel type of window construction, having one hundred per cent ventilation and means for inside window washing, and which is exceedingly simple in construction and may be produced in metal or in wood at a cost very little in excess of the cost of the old type of'double hung sash construction.

The invention also contemplates the provision of a window construction which eliminates binding of the sashes and difficult manipulation of the window.

Other objects and advantages of the invention will be hereinafter specifically pointed out or will 5 become apparent, as the specification proceeds.

1932, Serial No. 590,706

With the above indicated objects in view, the invention resides in certain novel constructions, combinations and arrangements of parts, clearly described in the following specification and fully illustrated in the accompanying drawings, which latter show embodiments of the invention as at present preferred.

In the drawings:

Fig. l is a broken vertical section taken through one of the upper corners of the window box, the

view also showing the pivotal support for one of the sashes.

Fig. 2 is a broken horizontal section taken through one side of the sashes and frame, the view showing the retractable Weatherstrip guide and one means for disengaging same when the window is to be pivoted.

Fig. 3 is a vertical section taken substantially through the center of the entire window, the view also illustrating the possible horizontal position of the two sashes and their relative positions in the frame.

Fig. i is an enlarged broken vertical sectional view of the means for retracting the Weatherstrip guides. i

Fig. 5 is a broken horizontal section taken through one of the vertical portions of the sashes and shows the Weatherstrip guide in a retracted position.

Fig. 6 is a broken horizontal section showing a modification in the construction of the embodiment.

Referring now to said drawings by reference numorals, the embodiment, as at present preferred, includes upper and lower sashes l0 and 11, respectively, which are mounted or hung in a window frame 12. The embodiment is adapted to be'constructed of metal entirely or of wood and metal, the latter construction being illustrated in the drawings.

The sashes are of conventional construction, the upper one 10 including upper and

lower rails

13 and 14 and side or vertical rails 15. The lower sash likewise includes upper, lower and side rails, 16, 1'7 and 18, respectively, each of the sashes carrying a window glass 19".

The lower rail 14 on the upper sash and the upper rail 16 on the lower sash are provided with conventional

bevelled portions

20 and 21, respectively, and the lower edge of the lower rail 17 is bevelled inwardly.

Each vertical rail of the sash is provided with a longitudinal channel 23 on the outer edge thereof, a substantially U shaped channel member or liner 2 being secured within said channel by means of screws 25. Within this liner a retractable combined Weatherstrip and guide member 26 is supported, the Weatherstrip member being constructed preferably of non-oorroding metal and being substantially H shaped in horizontal cross section. Any suitable, manually-operated means may be employed for moving the Weatherstrip member inward and outward. I have heretofore with good results employed the followin means. I drill a substantially oval shaped aperture through each of the parallel portions of the Weatherstrip member near the upper and lower portions thereof, the longer portion of each aperture being upright, as shown in 4. A horizontal shaft having a circular bearing portion 28, a non-circular central portion 29 and a reduced circular bearing portion 30, passes through each pair of apertures in the Weatherstrip member and is iournalled in the vertical portion of the sash. A pair of cam or eccentric members 31 are carried on the central or non-circular portion of the shaft and are spaced apart by means of a bushing 32, the cam members engaging the sides of the apertures 2'7 in the Weatherstrip member, as illustrated in Fig. Thus, as the shaft is revolved by turning a handle the weatherstrip member is caused to move inwardly or outwardly.

The inwardly facing vertical portion or jamb 36 of the frame is provided with a pair of channels 37, in which are secured a pair of metal trackways 38, one for each sash. "he trackway has a pair of outer longitudinal grooves 39 into which the Weatherstrip guide passes, and a central and wider groove 40 which acts a guide for a pivot 41 secured in each of the vertical rails of the sash, the pivot passing through suitable holes in the liner 2% and in the Weatherstrip member 26. In the drawings I have placed this pivot member midway between the upper and the lower portions of the sash. It is obvious, however, that a plurality of pivot apertures may be provided in various positions on the vertical rails of the sash in order that when it is desir d to project the sash, i. e., pivot it from the top, in order not to interfere with a fixed screen on the window, the pivot members may be removed from the central apertures and placed in the top.

At the upper end of the frame, on each side thereof, a pair of conventional pulleys 43 are mounted on a shaft, a chain is passing thereover. A sash weight 45 is secured to one end of the chain and the opposite end may carry a collar which fits over the outer end of the pivot. The sash chain is preferably long enough to accommodate the pivot member when the latter is inserted in a lower pivot aperture, as stated above. When the pivot members are changed the only other necessary change is to increase or decrease the length of the pulley chain.

When it is desired to insert the sash in the frame the sash may be held horizontally, raising one side thereof slightly in order to provide a clearance for the pivot members which are then inserted in the central grooves in the trackways in each side of the frame. The sash may then be swung vertically and the weatherstip guides moved outward into the outer grooves in the trackway.

In Fig. 6 I have illustrated a modified form of the construction of the embodiment wherein the Weatherstrip guide is retracted into the channel in the frame rather than in o the sash. In this figure I have designated the vertical rail of the sash as 18', the jamb as 36 and the pivot as ll.

On the outer surface of the vertical rail of the sash I provide a longitudinal groove and I secure therein a channel bar 51 constructed preferably of sheet metal and having a channel portion 52 substantially rectangular in horizontal cross section. In the jamb I likewise provide a somewhat deeper groove 53 in which is secured another channel bar 54 having a deeply recessed channel 55. I then mount a U shaped channel 56 within the recess 55 and provide means, as in the preferred embodiment, for moving it outwards, as shown in the drawings, and also retracting it. In either position the channel 56 acts as a guide for the pivot member 41. When it is in an outward position it engages the parallel sides of the channel bar 51, as shown, functioning both as a guide for the sash as well as for a Weatherstrip.

Considerable particularities of description as to materials, part details, capacities and utilities may have been herein indulged in, but it will be understood that these statements, made with ref erence to those two of the many possible embodiments of the invention which are illustrated in the drawings, are not in any way to be taken as definitive u" limitative of the invention. Inasmuch as many apparently widely difierent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawshall be interpreted as illustrative, and not in any limiting sense.

It is also to be understood that the language in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
