This invention relates to improvements in screen and storm sash mountings for windows. v

The main object of the invention is to provide a mounting or arrangement whereby screen and storm sash may be initially in stalled and subsequentlyremoved or replaced in a window entirely from the inside thereof, thus eliminating the use of ladders, scafl'olds '10 or the like at the outside of the window.

Another object is to provide a mounting of this kind equally applicable to either wood or metal window frames.

Another object is to provide a mounting having simple and positive locking means and which will require a minimumof alteration' in the window frame in the process of installing the sash. l 7

With these and other objects in view, the

v invention resides in-the novel construction and arrangement of parts as hereinafter fully set forth and claimed, reference being bad to the accompanying drawings wherein Y F igure 1 1s a vertical section through a window frame of wood,"showing the lower screen or storm sashin the process of being mounted in place; i Figure-2 is a view similar to Figure 1, but

I Figure 9 is an enlarged vertical cross section'throughthe head or upper portion of the .50

spectively the upper and lower screen .or storm sash. The sash B andC-comprise the usual sides or stiles 1, meeting rails 2'and'3, '65 andtop and bottom rails Land 5, forming rectangular frames on or; in which the screen or storm covering is placed. I As thus formed,

the sash B and C are intended for mounting in the window frame A outwardly of the up- '70 per and lower window sash Gand 7 therein, the said sash B and C being'of such size as to close the opening in the frame A when the upper sash is disposed above and1in line with the lower sash. The meeting rails 2 and 3 are rabbeted at 8 to overlap and form a tight joint as shown in Figure '2.

. In accordance with the present invention and in'preparing the window frame A for the mounting of the sash B and 0, side and head so stops 9 and 10 are secured to the frame A outwardly of the window sash 6 and 7 and in the angle formed at the junction of the head and side casings 11 and'the blind 'stops12 of the frame A.- These stops 9 and 10 are rabbeted along their inner corners as shown at 13 to receive the complementary rabbets 14 in' the stiles 1' and top rail 4 of the sash B and C, whereby a tight joint is provided between the said sash and stopsand whereby PATENT OFFICE 831d. sash a I are held against outward movement in the frame A. It will be noted that the stops 9 and 10 extend inward beyond the plane of the inner faces of the blind stops 12, so that the allowable width of the sash Band C is less than the distance between the blind stops at the sides of the window frame, this for the purpose of allowing the said sash to clear the blind stops and other parts of the window without coming in contact with and marring the same. Approximately midway between the center and lower ends of theside stops 9, the rabbeted corners 13 thereof are mortised out a short distance to provide recesses 15 in which the lower sash locks 16 are mounted,

these locks being formed of attaching plates 17 provided with inturned lugs or cars 18 along their margins as shown in Figure 5.

The locks aresecured in the: recesses 15'by screws 19 passed through said plates 17 the lugs 18 being thus spaced outward'with respect tothe angle formed by the rabbets13.

substantially vertical position:

At their upper ends the lugs 18 are bent outwardly at right angles} as designated at 20.

The lower sash C is provided with looking pins 21 driven in the outer lateral margins of its stiles 1 and projecting a short distance therefrom. To mount the lower screen sash C in the window frame A, the lower window sash 7 is raised as far as possible and the sash C is then passed through the opening thus formed. As the upper end of the sash C strikesthe "side stops 9, the sash is upward'until its lower end clears the window sill at which t me the saidlower endmay then beswung outward in the frame to a 'ing'pi'ns 21 come into line with the outwardly turned fends 20 of the lock lugs 18, the sash 'C is p'ushedoutward in the window frame, causing said pins 21 to pass over the said lug.

The screen sash may'then be lowered untilits bottom rail 5 meets the window sill, the

' m'e'eting rail '55 upper end of side and head screen sash C is thus restrained'against up- -ward movement'while the upper sash B is in place, and by locking said upper sash against an inward movement at its upper end, a rigid and safe screen is provided. This locking of the upperscreen sash B is accomplished by ailatch 22 pivoted at 23 in a slot 24 provided verticallythrough the top rail 4; of the sash the slot 25.

pushed angularlyf As the lockand adapted to enter a slot 25 cut in the head i stop 10 as clearly shown in Figures 6 and7.

The latch 22 is operable from the interior of thewindow frame by a handle 26 and of course serves to prevent the aforesaid inward B when engaged with swinging of the sash In Figures 8 to 11 inclusive, the mounting of the sash Band C in a metal window frame A is shown. In this case the side and head stops 9 and 10 are formed of angle irons 9a and 10a secured to the frame A by screws 27' and have their inwardly extending webs 28 disposed outwardly with respect to the windowframe whereby the sash B and G will I enter into the open angles of the said stops 7 and will be restrained against outward movement by the said webs 28 in. a manner similar to the rabbeted" stops 9 and 10. Approximately midway between the center and lower.

ends of the "side angle'irons 9a,lpins 29 are threaded in the webs 30 of the saidirons and are extended inwardly therefrom. The stiles 1 of the lower sash C areprovided with lock- 7 ing plates 31 on their outer faces, which plates are provided with slots 32 opening at their lower ends at the outermost edges of the said plates whereby to receive and hold the said pins29 when the lower sash is mounted in the window frame. The actionof mounting both the sash B and C is identicalcwith that first described with reference to the window frame A, and it is not thought that further description is necessary. To look the upper "i screen sash Bin place, a latch 22a identical in'mounting'and operation to the latch 22, is provided and is adapted to enter and lockingly engage a slot 25a provided in the upper angle iron 10a as'shown' in Fi ure 9.

From the foregoing lt'wlll e evident that the screen or storm sash may be readily rior thereof and may be as readily removed when necessary, the-removal being accomplished by first unlocking and removing the upper sash and then raising and removing-the lower sash as will be readily understood. The performance of'these operations entire ly from within the window or room'has manifold advantages particularly in cases where the windowsare located a considerable distance above the ground or street level. The use of two sash for each window is of advantage in the storing or transportation of the sash, especiallywhen the windows are large.

7 hile I have herein set forth a certain preferred embodiment of my invention, it is understood that I mayvary from the same in minor structural details, so as best to construct a practical device for the purposes intended, notdeparting from the spirit of the invention and within the scope of the appended claim.

I claim:

In a device of the kind described, a' sash "mounted in the window frame from the inte-
