COMBINATION SCREEN AND STORM-SASH.

Application filed October 23, 1919. Serial No. 332,665.

To all whom it may concern:

Be it known that 1, WILLIAM R. STER ER,

a citizen of the United States, residing at Chicago, in the county-of Cook and State of Illmois, have invented new and useful Improvements in Combination Screens and Storm-Sashes, of which the following is a full clear, and exact description. My invention relates to combined screen and storm doors and particularly to means for retaining said screens and storm doors ina frame permanently secured in a doorframe, or window frame.

The object of my invention is to avoid the difliculty usually experienced in removing the storm windows and substituting screens, or vice versa, or removing either of these parts -for cleaning or for repairs, and to restore them to their places again easily and quickly. This I accomplish by the means hereinafter fully described and as illustrated in the'drawings, and as particularly pointed out in the claims.

In the drawings:

Figure l is a front elevation of an outer frame in which a-plurality of sashes are arranged and secured in accordance with the invention.

Fig. 2 is a section on line 2, 2, Fig. 1.

Fig. 3 is a section on line 3, 3, Fi 1.

Fig. 4 is a section on line 4, 4:, Fig, 1.

Fig. 5 shows in top and side 'view'a fas:

tening plate.

Fig. 6 shows in top and side view a part co-acting with the fastening plate.

Referring to the drawings A represents a rectangular frame, which is preferably made of wood and of such dimensions gllat 1s frame consists of upright strips 6, 6, a lintel 7; a lower rail 8, and an intermediate rail 9, all of which are fastened together in any suitable manner. The inner edges of the uprights, the lintel and the base rail are rabbeted, and both the upper and lower edges of the intermediate rail are likewise rabbeted.

The rectangular frames of the screens or storm-sashes that are to be inserted in the space defined by the lintel, the uprights and the intermediaterail, and the intermediate rail, the uprights and the lower rail, have their marginal portions seated in said rabbeted edges of the outer frame, and I prefer that the frames 10, 10,-of the screens or the storm-sashes should correspond in Specification of Letters Patent.

thickness to the depth of said rabbets substantially as shown in the drawings.

About midway of the height of the vertical side members of the screen or stormsash, each frame thereof has plates, 12, countersunk into the surfaces of its vertical edges and secured to the same by screws or otherwise, so that the outer surfaces will be flush with the edge surfaces of said members. v These plates have projecting lat- Patented Ma an 1921.

erally therefrom and made integral therewith, pins 13. The outer surfaces of the vertical members of the doorframe A have, about midway between the intermediate rail and the lintel, and the base-rail and the intermediate rail, plates 15, and the said vertical members back of the central portionof these plates 15 are cut away or recessed to form a pocket. At a point about, say, one half of an inch, below the pins 13, said plates 15 have laterally elongated slots 16, made therein that extend from the edge of said plate 15, next'the screen or storm-sash, and are of such dimension that said pins can enter laterally therethrough. These plates 15 are slit upward from the inner ends of said slots to form resilient tongues 17 and the lower portion of these tongues are curved outward.

The screens or storm-sashes are lnserted 1n place by putting the ends of the upper edges thereof in the rabbets of the vertical members of frame A, within, say, an inch of the lintel and of the intermediate rail, respectively. When the upper screen or sash is thus placed in position, its lower edge will be one inch below the upper edge of the intermediate rail. Said screen or sash is then moved upward until the pins 13 register with the slots 16, whereupon the screens or storm-sash is pushed against the frame A and at the same time pushed upward, so that said pins will pass through said slots and back of tongues 17. When this is done the frames of the screens or storm-sashes will snap into place and must be retained in their rabbeted seats in the rectangular frame.

The lower screen is secured in place in the same manner as'the upper screen. In order, however, to prevent the screens or sashes getting loose in their seats, and becoming subject to involuntary movement, I prefer to secure the upper edge of the upper screen or storm-sash and the lower edge of the lowen screen or storm-sash by means of turn- buckles 18 and 19, that are secured to the baserail and to the lintel of the doorframe-l-I,

respectively, substantially as shown in'the drawings. Ialso prefer to secure the upper strip of the lower screen or sash and the lowerstrip of the upper screen or sash in? such manner that neither-of them will have any lost motion. I accomplish this by means of one or more pins 20, which latter are of such length that they can be dropped down through alining holes made in the lower strip of the upper screen or sash; the intermediate rail of the door frame, and the up per strip of the lower screen or sash, until the heads of said pins prevent thefurther downward movement of the same.

It will be understood that the intermediate rail of the door frame A, can be dispensed with, and said frame be made to conform to the area of the lower sash for a window and that one screen or storm-sash can be inserted therein so as to'accomplish the application of my lnvention to windows.

Such application of my invention to win 7 dows is not shown in the drawings,but its use for such purposes- 1s so obvious thatno advantage would be accomplished by illustrating'it. A

The manner of inserting the screens or storm-sashes has hereinabove been explained. In order to remove the same from the main frame, the pins v20, are lifted out of their holes, the turn-buckles are turned horizontally and the lower edges of the screens or sashes as the case may be, are

pulled outward until they are free from, the

rabbet and then downward until the pins 13'register, with the slots 16 in the plates 15, whereupon the said screens or sashes are moved on outward to cause the said pins to pass out of their said slots thus releasing the screens or sashes from the doorframe.

What I claim as new is:

1. The combination with an outer open rectangular frame adapted to 7 be perma- 4'5 nently fastened in a door or window frame and having its inner edges rabbeted, arid plates secured. to the margins of said edges having transverse slots therein and slit vertically from said slots to form tongues, of an inner frame adapted to be seated in the rabbeted edges of the outer frame, and pins projecting laterally from the side edges of said inner frame that are adapted to be passed through said slotsand confined in recesses in the outer frame back of said tongues, said tongues being adapted to guide said pins through said slots.

2. The combination with an outer open rectangular frame having its inner edges rabbeted and plates secured to the margins of said edges, having transverse slots therein, of an inner frame adapted to be seated in a the rabbeted edges of the outer frame, pins projecting laterally from the side edges of said inner frame, and adapted tobe passed through said slots and confined in recesses .passed through said slots and confined in recesses in the outer f'rame'back ofsaid plates and means integral with said plates for guiding said pins through said slots.

In witness whereof I have hereunto set my hand this 23 day of July, A. D. 1919. WILLIAM R. STERMER. Witnesses: Y

EVA STREIT,
