Application filed February 1a, 1923'. Serial No. 618.762.

To all whom it may concern:

' 'Be it known that I, GUmo M. SAGERDOTE, a subject of the King of Italy (declarant of intention of becoming a citizen of the United States), residing in the boroughof of New .York, county of Queens, and. vented: certain new and "useful Impro'vements in Rolling Screens, of which the following is' a full, clear, and exact description,

drawings, forming a part of this specification.

This invention relates to improvements in the construction of window screens or shades of the rolling type, being particularly adapted for use in connect on with rolling screens. v

Its primary object is to provide a positive and efiicient locking mechanism for the sides of the screen or shade, preventing its bulging or pulling out of the side guides under pressure.

A further object of thisinvention is to' rovide a novel and im roved type of lockmg mechanism for win ow screens or shades of the rolling type, whereby'the screen or shade may be locked at any .position against the action of a spring roller to which the same is attached, and may simultaneously'be locked at the sides against-bulging or pulling but at the sides.

A still further object is to provide an improved construction of clamping meansfor .the sides of a rollingscreenor shade, whereftion and tear of the flimsy fabric of which the screen is generally composed.

by wear and tear, of the screen or shade itsel is prevented.

' is permanently applied With these and other objects in view, as will more fully appear as the description proceeds this invention furthermore consists in certain novel and improved constructions and arrangements ofparts, as will be hereafter fully described and claimed 1n the appended claims.

la the construction of screens of this character, considerable difficulty has been-heretofore experienced in preventing the screen from bulging or pulling out at the sides.

under the action of wind pressure orcarcless handling, as well as from sagging at the sides under the action of the tension which between the top and the bottom of the same. This type of screens generally consists of a strip 0 wire cloth attached at one end'to a spring roller on which the same is wound when inopera- State'of New York, have inbeing had to the accompanying which is attached to the screen,

tive, being concealed from view b a casing within which said roller is ordinarily mounted. The free end of the cloth is attached to across member which is used to operate the screen, and which is generally guided so as to constantly remain parallel to itself during its motion, on said cloth In order to cause the screen to stretch and to lie flat throughout the entire window space, however, under tension at all times; and'under this tension, unless prevented from doing so, the sides of the screen will sag,.and the surface thus exerting of the cloth and its texture will in time become permanently deformed, interfering with the proper winding and unwinding of the same. i I

Various means have heretofore been dean even tension throughout its entire length.

the roller ismaintained vised therefore, to prevent inward motion of the sides of the screen. In some instances, hooks or other retainin means have been attached to the sidesof t e screen, and compelled to travel along a predetermined course by guiding means; but anything inevitably causes increase and unevenness of the d1 In other mstances, means for clam ing the sides throughout their 'entirelength We been adopted, which I have found to. be fairly effective, but which are opento various objections. Among these, are the necessity of a separate and additional operation of said. lamping means subsequent to the setting of the screen in position, and the use of operating means ance of the screen. Another objection is the wearing out of the sides of the screen, which will in time occur, due to the rubbing action of wedge acting clamping means applied directly against the screens surface.

My invention obviates these various unsatisfactory features by providing locking means for the sides of the screen which will for the same which are not concealed and which mar theappear neither alter its physical condition, norincrease its diameter when winding; and by providing locking means against the action of the roller, which-operate simultaneously and in conjunction with said side locking means. I also provide a novel and simple method of guiding the motion of the cross member or bottom rail, which does away with a number of parts now used for this purpose in the construction of screens of various descriptions.

A specific embodiment of my invention is shownin the drawings, which are intended for illustrative urp'oses, and not in a limiting sense. In t e same:

Fig. 1 is a front view in elevation of my improved screen applied to a window, in its extended position;

Fig. 2 is a fragmentary front view in elevation of the upper right handcorner of said screen I Fig. 3 is a fragmentary sidesectional view of the same; Y I.

Fig. 4 is a fragmentary plan sectional view of the same; I

Fig. 5 is a plan sectional view similar to Fig. 4, showing the side of the wire cloth released by the clamping means; i

Fig. 6 is a fragmentary front view in elevation, partly sectioned, of one of the ends of the bottom rail; and,

Fig.7 is a detail sectional view of a side rail showing a difi'erent' mechanism for operating the clamping means.

The frame of the screen consists of two upri hts or side rails 10, 11, and a cross mean r or casing 12, which is shown at the top, and within which is mounted roller 13.

While said three members may b connected to each other in a permanent mannor, I prefer to adopt a construction which allows of the various parts to' be separated and reassembled at will; this construction possessing marked advantages in packing and shipping operations. Accordingly, I show each side rail attached to the casing by means of an angle piece 14, 15; each angle piece supporting one end of shaft 16,

. on which roller 13 is rotatabl mounted. Y

. held together y. means of two tie r Each angle piece is provid with an inwardly extending portion 17 whiclnfits and is inserted within one of the endsof casing 12, and a longitudinally extending portion 18 which in asimilar manner fits and is inserted within one of the ends of one of the side rails.

The two an le pieces and the casin are s 19 20,'andby a third tiered 21, which is in serted through a bead formed at 22 in the casing and which also stifi'ens the casing itself. Connection between each angle piece and its side rail is maintained by means of a tie rod 23 which also acts as a pivot for the clamping member, as willbe explained.

The side rails are in the form of an enincense closed casing formed with a slot 24 between its rear and its inner sides, and casing 12 is formed with a slot 25 between bead 22 and rear side 26, which registers with slots 24: when the frame is assembled.

A spiral spring 27, one end of which is attached to shaft 16, and the other end to roller 13, is set under tension, and maintains in the roller a tendency to wind up the wire cloth 28 which is attached to the same. Tothe free end of saidwire cloth is at tached the bottom rail 29, by means of which the same "may be extended or contracted, said cloth passing through slot 25 and having its sides extending through slots 24 within the side rails.

The wire cloth is attached to the bottom rail in any suitable manner. Through its various features of construction, the bottom rail is enabled to perform three different functions, viz:

1.Operating the cloth with an even ten-' sion for its entire width, the bottom rail being maintained constantly parallel to itself during its motion by having its ends against the tension of the spring roller by means causing friction to take place between said bottom rail and its side longitudinal guides.

3.-perating the side clamping means. ,The clamping pressure .proper, at the sides, is exerted by the. wedging action of he cam'surface 300i a iclam ing rail 31, inserted on tie rod'lg23, an capable of pivotal motion thereon; said being thus mounted within the side rail and extending as practically its entire length. 7 Angular, {motion of said clamping rail aroundits-pivot, will cause its cam surface 30 to press a 'ainst or to release the surface against "whic the same abuts; which may,

if desired, be the wire cloth itself, which would thus he clamped between the back of the side rail and the clamping rail, but whlch would be subjected to a rubbing action during the clamping operation.

To prevent the wear on the cloth which might possihl ensue, I prefer-to employ a clamping lea 32,-pivoted at 33, receiving clamping rail with a packing of materia having a certain degree of resiliency and plasticity, preferabl rnhher, as shown at 34. Such a material will not only create better frictional conditions on account of its higher coetli: cient, but it will actually fill the spaces between the wires of the wire cloth, and actually look the same against side motion.

Clamping rail 31 is formed with a beaded 'asaaasa edge 35 by means of which the rail is operated and which serves at the same time as] y 43,- 44 45 designates the wire cloth, 46 a alon'gitudinal guide for the bottom rail.

-To this endthe bottom railis made cot lapsible and provided at each end with an arm 36 irig up to an end 37 inserted on said beaded edge 35 and-'slidably and pivotally movable thereon. By moving the two arms 36 inwardly or outwardly at the same time, therefore, the two fjclamping rails will simultaneously release or look the sides of the wire cloth. Furthermore, if the pressure exerted by said arms 36 against the for instanceby means of clamping rail to move the same to its clamping position is maintained, the same will v create a 36 and the clamping rails which" will effectively lock the bottom rail preventing rewi'nding of the cloth ,until said pressure is released.

' In the .device illustrated, the clamping action takes place when the two arms 36 are expanded, said outward ,',movement of the arms being caused in any suitable'manner, springs as shown in the drawings In the same, arms 36. are slidably mounted within the bottom rail proper, and are each provided with a rod 38 extending toward the center of therail and terminating in an exposed clip 39. A spring between the central portion of the rail and the rear of each ,arm 36 tends to force said arm outwardly, and exerts the pressure necessary to operate the clamping rail connected thereto ing action; at the sametime,

I preferabl and tolock the bottom rail in position.

By applying the thumb andthe tip of the first finger to the two clips 39,- same may be forced towards each other, movingx arms 36 inwardly, and therefore releasing t e clampthe bottom rail may be operated so as to lower or to raise the screen to its new position, when by releasing the clips the screen will again become locked. I

The lower edge of the bottom rail is provided with means for holding a rubber l ade 41 insuring a tight closure of the screen when in operatin position, for instance a slot 42 through wh1chsaid rubber blade may be inserted. Felt may also be used if desired.

The essential advantage of my invention resides in the fact that a positive side lockpractice.

inserted through slot 34 and extend-' friction between said arms ally pressure should be re course contraction'of,the'bottom rail. It may also be noted that when springsare used, or other cured to the angle piece by means of tie rods clamping leaf pivoted at 47, and 48 a pack-. mg with which the same is preferably provided. V I,

Like in the previous case, the bottom rail is made collapsible, .49 designating one of its movable arms provided with an end portion 50 slidably andpivotally connected to a longitudinal bar 51, integral with arms 52 hinged inside of the side rail at 53. Bars 51, one at each side' of the screen frame, thus constitute the guidingme'ans'foi: the bottom rail, as well as its locking means when the same is allowed or caused to expand- In the same,,the side rail is se- The clamping leaf, 46, is in this case operated by means of a toggle joint constituted by arms 54 pivoted to said leaf at 55, pivotconnected at 56 to arms 57 attached to a fixed pivot 58-inside of the side rail. When the toggle joint is expanded, as shown in the drawing, 1 the clamping action takes place, and, when theisame is contracted, by moving its joint 56 towards the left, clamping leaf 46 with its packing or pad 48 is caused to release the wlre cloth which will thus be'free to move. v

The toggle joint is operated by arms 52 through 'connections'59 between saidarms and joint 56, and' its operation is therefore simultaneous with, and controlled by the operation of the bottomra'il. L 1 In the devices shown in the drawings, I

use springs in order to create the pressure necessary to produce the (clamping action,

I and the required frictional resistance between the bottom rail and its guiding-bars, the springs being for convenience ofconstruction, located in the inside of the bottom rail. Both the cam and the toggle joint action described multiply the pressure exerted by the spring manifold, so that in practice I have, found springs of moderate no pressure and. such asto be easily operated by a woman in themanner-describe'd, to be' quite-satisfactory. 7 i

In such cases" where more than normal uired, for instance, in

connection with win ows of abnormal dimensions, means other'than springs may of be used to control the expansion or means as well, the same do not necessarily have to be located in the bottom rail in order toobtain the desired result.

From the foregoing 'it is seen that I provide a novel form of control for locking the sides of the wire cloth; clampin means, of novel design for effecting the c ampin action; a novel and simple method of gui ing the longitudinal motion of the'bottom rail; a novel method of locking the bottom rail; and a novel method ,of simultaneous lid control of the bottom rail and the side clamping members. I

As previously stated, thespecific details of construction may vary from those shown without departing from the spirit of my invention; and I reserve myself the right to carry my invention into practice introducing all those changes and modifications which might be deemed advisable in order to satisfy varying conditions, and such as may enter, fairly into the scope of the appended claims.
