Application March 11. 19:1, Renewed August Serial No. 131,351 1, 939

Claims. '(ol. 189-64) My invention relates to improvements in window construction, particularly to windows having a plurality of window sashes horizontally slidable on rollers running on rails, and it is the principal object of my, invention toprovide an inner set of such windows, and an outer set of so-called storm windows, the sashes of which are spring pressed and are adapted to slide into suitable pockets or chambers formed in the window casement or frame by readily operated means, so that the windows may assume any number of desired relative positions for either closing the window entirely or partly, or opening the same for ventilating purposes or the like, while the operation of the inner window sashes will simultaneously also operate a screen to protect the window when the sashes are in their pockets.

Another object of my invention is the provi- 20 sion of a window of this type, the panes of which are readily removable from their frames or exchangeable, so that broken glass may readily be replaced without; the necessity of employing skilled help.

Still another object of my invention is the provision of a window requiring no special care for its maintenance, no sashes of v a permanent nature or ropes or weights for, its operation, and which does away with the hanging of storm windows and screens seasonally, while requiring no material change in the construction of a building. p

A further object of my invention is the provision of a window of the character'above described which ensures a tight closure at all times requiring no weather stripping or similar tightening means to prevent leaking or the entrance of snow or moisture, while the painting of the sash frames, glazing of the panes as well as the cleaning of the windowsby unskilled labor is greatly facilitated and can easily be done from the inside of a room, as each pane may readily be removed with unusual ease.

A still further object of my invention is the provision of a window which will allow an efilcient ventilation of a room by the adjustment of the relative positions betweenthe inner windows and the outer storm windows, compelllngthe air to follow a sinuous or serpentine path.

Further objects and advantages of my invention reside in the protection of the screen from unnecessary exposure, as it is rolled up and protected or concealed when the window is closed completely, while the screen may be operated simultaneously with the operation of the sashes or, as it is detachably secured the same, may

also be operated by hand.

My window besides, will allow the admittance ofplenty of, fresh air to any desired degree, when for instance completely open with the sashes in. their pockets, and in this position, missiles thrown through the window will not be apt to do any damage to the window panes.

Furthermore, by means of its tight closure and by virtue of the double window construction, a decided saving in fuel for heating purposes will be obtained.

I may moreover, build my window frames in double or triple easements, and single windows may be constructed in a building as close as for instance 10 inches apartfrom glass to glass. I

may use the screen at will to any extent, as the same is detachable from the sash to which it is secured, while a simple handling of the: devices for operating the windows will allowthe regulation of the opening of the windows and storm windows to any desired degree without undue strain on the operator, and the finish and trim of the window frame may be selected at the discretion of. the owner or user, while the ready installment and removal of the windowsmay be effected without the necessity of employing specially skilled help, as for instance the services of a carpenter or the like mechanic.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and will then be particularly defined in the appended claims.

In the accompanying drawings forming a material part of this invention:

Fig. 1 is a front elevation of a window constructed according to my invention, partly in section, with the window closed.

Fig. 2 is a section on line 2-2 of Figurel.

Fig. 3 is a section on line 1-3 of Figurel, with the storm window closed, and the innerwindow open and protected by the screen.

' Fig. 4 is a sectional view similar to Figure 3, with the inner window open and the storm windows in their pocket.

Fig. 5 is a fragmentary, sectional view, the section being taken on line 5-5 of Figure 4.

Fig. 6 is a perspective, fragmentary, sectional view of a cornerof the window illustrating the means for holding the panes and for moving the window.

Fig. '7 is a sectional plan view of a modified form of my window with the windows open.

Fig. -8 is a view, similar to Figure 7 with the outer and inner windows in different positions for ventilating purposes.

As illustrated in Figures 1 to 6, a window frame,

the shanks of headed bolts ll extend, secured at their lower ends in presser bars it, while springs l1 between partition H and bars ll wound about the shanks of the bolts cushion the movements of the same and are normally tending to engage the presser bars it with the upper sash frame bars II to keep the lower sash frame bars in engagement with the housings I! for the rollers 22 running along rails formed with the partition I2.

The glass panes 22 are tightly held in their frame bars by means of the rubber sheathings 23 so that they can readily be lifted with their sash frame bars 24 out of the housings i9. These housings I9 have shoulders25 formed at their inner ends to firmly engage similar shoulders 28 formed with the casing of the next adjoining window. Pockets 21 are provided at the left hand side of the window casement into which the rails 2| extend on which the casings I! slide in staggered relation to one another.

A shaft 28 extends from the easement, and has its outer end squared, as at 29, for the attachment of a suitable crank handle, and this shaft carries a bevel gear 30 in mesh with a bevel gear 8| on a shaft 32 journaled in the easement wall, and extending lengthwise in chamber i4 where it is provided with a worm thread. The inner end of this shaft carries a sleeve 33 to which the outermost housing Isis attached, as at 34'. The inner end-of the shaft 32 is journaledin a bear-, ing formed with a bracket 35 secured within the casement.

In a similar manner the housings ii for the storm windows 22' slide on rails 2i, and the windows are arranged in staggered relation to one another on these parallel rails and have also shoulders 25' formed therewith to engage firmly similar shoulders 28' on the housings l9 of the next adjoining window. Also the panes of these windows are exchangeably held in their frames and sheathings as described with respect-to :the inner windows. I

The storm windows are operated by the following mechanism: A shaft 38 joumaled in a bracket 31 in the casement has its outer end squared,

as at 38, for the attachment of a suitable crank A screen 45 is wound about a hollow roller 46 journaled at its lower end with its inner rod 41 in a block 48 supported by a spring 4a in a depression in the chamber l4, while the spring 50 wound about the rod 41 in roller 46 acts in the same manner as the well known spring rollers for curtains and shades with the upper end of the roller 46 having the usual tenon journaled in partition wall II. The screen is guided over a guide 5!, and its outer end or edge is detachably secured by means of a forked element 52 and clamping bolt 53 and nut 54 to the outer end of the innermost window housing i9.

The modified form of my invention, illustrated in Figures 7 and 8 is generallymf the identical construction as aforedescribed withrespect to the preferred form of my windowconstruction, except for the arrangement of a pocket II on the lefthand side of the casement for the reception of the individual inner windows, while a similar pocket It is provided on the right hand side of the window casement for the reception of the storm windows, so that the windows may assumes relative position or podtions to one another, as indicated for instance in Figure 8 by the arrows l'l compelling the air to pass through a sinuous path. Upper and lower locking handles may suitably be arranged to operate the windows by hand if so desired, and to lock the same. I

The device operates as follows:

If it is desired to open the window fully, the

storm windows are shifted on their rails into 20 the pocket at the left hand side by the operation of the handle-spindle 28, and the inner windows are shifted into the pocket at the left by the operation of handle spindle 28. This operation will carry the screen attached to the outermost window along into the position shown in Figure 3, or if the screen isnot desired, it may first be disconnected from the window by removing the bolt and nut from the clamp 52. Thus a fully opened window will admit the greatest desirable amount of fresh air to a room.

If ventilation to any desired degree is desired,

the storm windows are partly moved into the which the outer and inner windows assume to one another.

If a cleaning, glazing or paintingof the windows from the inside of a room is desired, or an exchange of broken glass, it will only be necessary to remove the sash frames out of their sheathings', while the springs and bolts will hold the sash frames in place and the rollers in permanent engagement with the rails when the windows are mounted as such.,

It will be understood that I have described and shown the preferred forms of my invention only as a few examples of the many possible ways to practically construct the window, and that I may make such changes in the general arrangement of the construction and in the mak ing of they minor parts thereof ,as come within the scope of the appended claims without departure from the spirit of my invention, and the principles involved.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent is: y 7
