PINLESS CURTAIN STRETC-HER Filed Aug. 26, 1938 I :7 4/ i x 26 X INVENTOR Evan! ATTORNEY Patented Sept. 3, 1940 UNITE PATENT OFFICE 4 Claims.

This invention relates to curtain stretchers and more particularly to a device adapted to hold a curtain or the like with uniform tension or stretch throughout the edges thereof.

A major object of the present invention is to provide a simple, inexpensive device for stretching cmtains, when wet and heavy, in the same normal position that they will usually hang and without producing scallops in the edges thereof.

Priorto my invention numerous devices have been proposed to stretch wet curtains. The most common of these utilizes a frame usually mounted with the longitudinal axis in a horizontal position, the frame being provided with a large number or closely spaced pins on which the edges of the curtains must be hooked individually. Placing curtains on such stretchers is very tedious, time consuming and the operator almost invariably pricks his fingers on the pins. Other types have been provided in which the curtains may be stretched longitudinally but without any means being provided to prevent the sides of the curtain from pulling inwardly due to the longitudinal stretch. One of the main disadvantages of the prior stretchers is that they are not adapted to permit uniform stretching the full length and width of the curtain.

According to the present invention I provide means for holding the curtain from one end so that it hangs under the action of gravity to give a preliminary stretch and then I provide means to further stretch longitudinally and clamp the sides to prevent bowing inwardly.

Accordingly a further object of the present invention is to provide a simple, inexpensive device for simultaneously stretching curtains longitudinally and transversely thereof throughout the full extent thereof.

Another object is to provide a novel and improved device for frictionally engaging said ourtains throughout the full length thereof.

Another object is to provide an improved device for sup-porting the upper and lower edges against bowing while permitting the lateral margins of the curtain to be clamped and the curtain stretched transversely.

Another object is to provide an improved stretching device that can be easily and quickly adjusted to stretch curtains, or the like, of various lengths and shapes and hold such curtains free of any wrinkles or scallops in the edges and which will be inexpensive, durable and efficient.

Other and further objects of the invention will appear from the following description taken in connection with the accompanying drawing, in

.which;

Figure I is a front elevation of a device embodying the present invention, showing a curtain in place.

Figure II is a side elevation on the line III-l1 of Figure I.

Figure III is a horizontal section on line IIIIII of Figure I.

Figure IV is a vertical section along line IVIV of Figure I.

Figure V is a vertical section along line VV of Figure I; and

Figure VI is a perspective View of the guide and rod holding unit shown in detail section in Figure III.

Referrin to the drawing an illustration of the invention comprises an upright frame I, preferably supported by suitable feet or pedestals 2. The frame I has one side member 3 which serves as part of the frame and as one of the clamping members for one side of the curtain to be stretched. Suitable upper and lower cross members i and 6, respectively, are secured to the side and lower cross members 4 and t through means:-

of the Z-shaped members 9 and III suitably secured to member II as shown in the details of Figures IV and V.

suitable telescopic rods I2 have one end supported by screws I3 on the side member 3 and the other ends are supported by the clamping memher I I by means of suitable screws M. It is to be noted that the cross section of members 3 and II is as shown in Figure III and that the screws l3 and I l are located in the notch, in order that the edge of the curtain will be in a position to be clamped in a manner presently to be described.

In order that a wet curtain may be stretched from corner to corner means are provided to adiustably hold the upper and lower edges of the curtain in a position for the clamping means to engage the curtain from end to end of the lateral .inargins regardless of the position of the ends when the curtain is stretched the desired amount.

Since the construction of the clamping members .i and II is substantially identical only clamping member 3 will be described. To this end, the side and clamping member 3 has a narrow groove It in its back face in which a tongue I! of a guide member I8 is adapted to slidably engage.

.The guide member I8 comprises a "(I-shaped member having a short leg I9, with which the tongue II is contiguous, and which is adjacent to the back face of member 3, and a long leg 20 embracing the front face thereof The leg 20 has integral protuberances 2!, on which one end of telescopic rods 22 may be held. The ends of the rods 22 are flattened in order that the rod will not prevent the functioning of the clamp. Although only two rods 22 are shown, it is to be understood. that this number may be varied as desired without departing from the spirit of the invention. v

The clamping members 3 and II are provided with clamping bars 23 and 2A which are preferably in two or more sections. The sections are. hinged to the members 3 and H, as at 26 and 27. The hinges may be conventional construction or, as shown, may consist of heavy, stifi' wire secured to the clamps 23 and 2& by suitable staples, or the l ike and may be. pivotally supported on the members E and M, respectively by other: staples 28.

The above preferred construction facilitatesv clamping of the side of the curtain by permitting flexing of the

clamps

23 and 24 as the edge is progressively tightened.

The inner faces of the clamps are provided with a resilient strip which may be rubber or like material. which sufiicient friction for the. curtain and which is resilient enough to yield over the ends of the telescopic rods 22 and at the same timehcid the curtain substantially throughout the full length of the edges.

allow for further stretching suitable tightening means may be provided to hold the clamps tight against the bottom of the notch. To this end, a

plurality of small wedges 3!, having an outer face inclined to the clamping bar are provided, against which suitably pivoted elements 32 may be engaged to hold the clamping bars tight against the curtain.

In using the construction above described a curtain, or the like, indicated at 33, having a looped hem is placed on one of the upper telescopic rods l2 and likewise a hem'in the lower end of the curtain is placed on one of the lower rods 22 The left hand side of the curtain will be given a preliminary stretch by pulling the lower rod down, if desired, to a prearranged mark to stretch the curtain a definite amount. The

clamping bars 23 are then clamped down to hold the left hand edge of the curtain. Next the right band edgeof the curtain is stretched preferably to a prearranged mark and then the curtain is stretched transversely by moving the clamping member ii to the right by means of the handles S it When the curtain is wet and is stretched laterally no means are needed to hold the clampmember it since the friction of the wet curtain will prevent itfrom sliding back on the rod From the foregoing it will be readily apparent that I have provided a simple, inexpensive, and durable curtain stretching device which is capable of simultaneously stretching curtains along all tour margins thereof.

Whereas, I have described my invention by re erence to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of. the invention defined in the following claims:
