Specification of Letters Patent. I

Application filed December 3, 1917, Serial No. 205,013. Renewed January 11, 1921. Serial No. 436,613.

To all whom it may concern: 1

Be it known that I, JOHN J. CHAPIN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Rolling I This invention relates to screens of the class which are permanently fitted to win dow frames or other openings of buildings, and having a flexible screen adapted to be rolled within a casing or housing provided preferably at the top of the window.

The invention has for its principal object to provide a rolling window screen having side guides for the unrolled screen andclamps therefor concealed within the guides, thereby, assuring a pleasing finish to the whole screen structure and avoiding unsightly accumulations of dust upon or within the screen fittings or mountlngs.

A further object is to provide a simple, and-practical rolling screen which may be inexpensively made and applied and 1s efiicient and durable in use, and which clamps the screen edges easily and securely without interferi with the free opening o-r closing orconvenient cleaning-of the WlIldow sashes. To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully descrlbed, the novel features being pointed out in .theclaims at the end of the specification.

In the drawings: Figure 1 is an elevation of a wlndow cas ing showing one of the improved rollingv screens as viewed from'the inner side and shown unrolled or extended for use;

Fig. 2 is a vertical-sectional view taken on the line 2--2 in Fig. '5, with the screen rolled up as when out of use;

Fig. is an exterior view of a window showing the screen fully extended;

Patented Aug. 16, 1921.

Fig, 8 is a vertical section taken on the I irregular line 8*8 in'Fig. 1, and

Fig. 9 is a detail rear sectional perspective view of the lower clamp bearing block in the right hand screen guide.

a Similar reference characters in the several figures indicate the same parts.

The numeral 1 indicates the flexible screen, preferably made of wire netting, secured at one end to a Spring roller 2, which is journaled at its ends in brackets 3, located above anopenin'g 4, such as a window bounded by strip 9 which looks this end of the screen within a dovetail shaped slot 10 formed in the inner wall of a hollow transverse screen bottom rail 11. The latter is preferably molded or rolled from sheet metal, and at its ends is closed by blocks 12, 12, shown in Figs. 1, 4 and 7. These blocks are slotted vertically at their outer edges which are guided "upon the laterally projecting inner flange portions. 14 of hollow metal guides at the sides of the window frame 5, which also comprise the inner wall 15 and a connecting wall 16. Each of the guides is securedat its ends, by screws 17, tothe face of the outer sash stop, or rail 18 of the window casing so that the guide flanges 14;, extend laterally inwardly toward each other. tion the guides hold the Screen close to the window sash and do not interfere with the closing of the shutters or blinds which may be. fitted within the casing 5. There may be one or more intermediate screw fastenings 19 for each guide, depending upon its length, as Shown in Figs. 1 and 2. These screws1 9 are set into the frame portion 18 before the guide is applied thereto, the screw heads standing off from the frame sufiiciently to snugly receive beneath them the narrow base wall 16 of'the guide which is transversely slotted at 20 to receive the body or stem of the scre'w,the head of which passes laterally through a curved slot 21 made in the inner side wall 15 of the guide. The communicat- In this posithe latter sufiiciently to provide between them a vertical groove or channel 22 in which moves one edge of the screen. Fitted within the ends of the guides are short upper and lower bearing blocks 23 having transverse openings through which pass screws 17 or other securing devices, which thus firmly support the blocks while also holding the guide to the window frame, and the bear mg blocks reciprocally impart necessary strength to the guide to resist all strains incident to tightening of the screws 17. f

An important feature of construction consists in inclosing the screen edge clamps within the screen guides *to assure a more neat and pleasing finish to the guides and the clamps and to the whole screen structure, and also to avoid unsightly and not easily removed dust accumulations, than prevails when the clamps are arranged outside of the guides and more or less in full view. In this constructive feature the screen clamps inclosed in the guides may have any desired form and mode of operation, but it is preferred to form the clamps of a rod extending for practically the full length of the guides. The clamping rod, indicated by 24, has at its opposite ends journals 25 fitted in recesses in the opposed lower and upper faces of the respective upper and lower blocks 23, preferably nearer the outer ends of theblocks and in such relative positions as to cause the rod, when turned from the inoperative position, shown in Fig. 5, to that shown in Fig. 6, to bind throughout its entire length upon the inner surface of the wall 15, near its strong laterally curved edge, whereby the clamp rod 24 and both the inside and outside walls 14 and 15 of the guide coact to mutually brace each other while the edge of the screen 1 is clamped by the rod against the outer flange 14. A

further improvement consists in forming the screen clamping rod in a manner assuring its action gradually lengthwise upon the screen edge. This is conveniently accomplished by making the rod of a flat bar,

with rounded edges and imparting thereto a lengthwise twist, or a partial turn from end-to end, as shown in Figs. 2, 5 and 6, which causes the rod when rotated to exert its clamping action gradually upon the screen edge from one end portion of the screen to the other, thus making the manual operation of the screen clamps easier and more certain and bringing less strain upon the screen material than occurs when the screen edge is clamped simultaneously along its whole length. For turning the clamp rod 24, a drop handle 26 is provided having an end tongue 27, Inovably fitting within a vertical groove in the outer end of a horizontal stud 28, fixed in the clamping rod 24,

and coupled to the stud by a pivot pin 35.

Whenassembling the parts the clamp rod 24 with its fixed stud 28 is first slipped endwise into the hollow guide, and the rod adjusted .to project its stud 28 outwardly through a slot 29 in the wall 15, as shown -26 may now be coupled to the stud 28 by ;the pin, 35, and will normally depend 1n front of the screen guide.

When the screen 1 is drawn downwardly in its-two guide channels, the handles 26 will be raised horizontally and will then be turned about one-quarter around toward the screen, as shown in Figs. 1 and 6, thereby causing the rods 24 to securely clamp the opposite edges of the screen against the guide flanges 14. The handles being then released drop to a vertical position at the inner edges of the guides. Whether the screen 1 be drawn downwardly and clamped, or unclamped and rolled upon the roller 2, the drop handles 26 are practically the only visible portion of the screen clamping mechanism and they present a pleasing appearance in keeping with the appearance of the clamp concealing guides, withoutmarring the architectural symmetry of the window design or trimmings. 1

It will also be noticed that'by concealing the screen edge clamps 24 within the guides, the nature of the screen clamping-mechanism is not readily apparent because of the lateral projection of the guide flange 14 beyond the inside wall 15 so that an intruder would find it diflicult to pry the clamps loose from the outside of the window without destroy: ing the screen, hence this invention permits keeping the window sashes open for ventilation while providing a substantial measure of protection against the unlawful entrance of an intruder. As an additional locking device the bottom rail 11 of the screen carries on each of its end blocks 12 a latch 30 pivotedto a lug 31, and having ahook end 39 adapted to automatically lock into the recess 32, made at the lower end of the edge of each guide flange 14, as shown in Fig. 1 of the drawings. The latches 30 swing outwardly at their lower ends and about at right angles to the face of the screen, and their inner plate portions preferably range about parallel with the screen and may be used as convenient finger grips in manipulating the screen.

The rotation of the engaging. edges of the clamping bars or rods 24 1s in a direction outwardly toward the screen to move its edges into contact with the guide flanges 14 and also laterally thereof, thus tending to draw the edges of the screen outwardly in opposite directions to stretch it with suflicient tension to cause'it' to lie flat over the entire opening and prevent it from bulging. In this position one edge of each clamping rod is in engagement with the curved edge of,

the inner flange 15 which serves as a bear-' ing or brace to stiffen the rod throughout its length and resist any tendency of the rod to buckle if pressure is applied 'transversely of the screen.
