HENRY H. KREIGE'R, OF BRADDOCK, PENNSYLVANIA.

CURTAIN STRETCHER.'

Application led February 15, 1922. Serial' No. 536,737.

To all 'whom t may con-cern.' f

Be it known that I, HENRY H. KREIGER, a citizen of the United States, residing at Braddock, State of Pennsylvania, have invented new and'useful Improvements in Curtain Stretchers, of which the following is a specification.

This invention relates to curtain stretchers, and more particularly to a curtain stretcherhaving means for supporting the same in upright or standing position.

One of the main objects of the invention is to provide a curtain stretcher of the character stated of simple construction and operation which may be readily produced at small cost. A further object is to provide a curtain stretcher which may be readily ydisassembled and, when disassembled, can be packed so as to occupy very little space. Further objects will appear from the detailed description.

In the drawings Figure 1 is a front view of the stretcher set up;

Figur-e 2 is an end view;

Figure 3 is a section taken substantially on line 3 3 of Fig. 1;

Figure 4 is a back view of one of the end bars and associated parts;

Figure 5 is a section taken substantially on line 5 5 of Fig. 4;

Figure 6 is a view showing the stretcher disassembled with the parts positioned closely adjacent to each other so as t0 occupy little space;

Figure 7 is a section taken substantially on line 7 7 of Fig. 6.

The stretcher includes a top bar l and bottom bar 2 each of which is provided in its outer face with a longitudinally extending groove 3 and with securing pins 4 projecting from this groove for securing the edge portion of the curtain lin the known manner. Bars 1 and 2 are each provided at one end with a series of spaced openings 5 and at the other end with an opening 6. Openings 5 and 6 of top bar 1 are adapted for reception of supporting and adjusting pins 7 carried by side bars 8 adjacent to the upper ends thereof. Openings 5 and 6 of lower bar 2 are adapted for reception of any one, selectively, of a series of supporting and adjusting pins 9 adjacent to the lower ends of the side bars. Each side bar is also provided with a longitudinally extending groove 8a from which project securing pins 4a similar to pins 4. By means of the pins 7 and 9 and the openings 5 and 6 in the top and bottom bars the effective width and lengt-h of the rectangular frame formed by the side and end bars may be readily adjusted as desired.

For supporting the frame when set up I provide brace-bars 10 pivoted at their upper ends, at 11, to the outer faceo'f the respective side-bars 8.- Each brace-bar 10 is provided in its inner face with a recess 12 adapted for reception of a rigid securing strip 13 pivotally secured at its lower end, at 14, in recess 12. At its other end strip 13 is provided with a hook element 15 adapted for engagement over the shank of a headed pin 16 secured in side bar 8.

The strip 13 co-acts with pin 16 to hold brace-bar 10 at an inclination to side bar 8, the two brace-bars thus acting to support the frame of the stretcher at an inclination, as in Fig. 2. To prevent any looseness of the stretcher frame when set up and supported by brace-bars 10 in the manner described, top bar 1 and bottom bar 2 are each provided with a rearwardly projecting block 17, this block being provided adjacent to one end of the bar and fitting snugly against the inner lateral edge portion of the adjacent side-bar 8 (Fig. 3). This provi-des simple and efficient means for holding the top and bottom bars at ri ht angles to the side-bars and serves to e ectually prevent all looseness or play between the bars of the frames.

Each brace-bar 10 is provided, in its inner tace, with a transversely extendiiw slot 18 which is of substantially T-shape 1n crosssection. The neck portion of the slot receives the shank of pin 16 and the head of the slot is adapted to receive head 16a of the pin when the brace-bar is moved into parallelism with side-bar 8 as in Fig. 4. The pin 16 acts to hold the brace-bar in its folded position adjacent to the side bar and prevents all looseness or play of the brace bar, strip 13 fitting snugly into recess 12 when the brace-bar and the side bar are folded together. When the frame is disassembled the brace bars and side bars are folded together and the top and bottom bars are positioned closely adjacent to each other the end of one of these bars being in contact with the block 17 carried by the other bar, as in Fig. 6. After this has been done the side bars 8 and brace bars 10 carried thereby are placed adjacent to the top and bottom b'arsjl the-stretcher, when disasseinbled,

being thus arranged so as to uforni a neat bundle which occupies but very little space. The stretcher constructed.` ll,v the manner illustrated and described nia i be readily produced. at small cost and can bequickly, and easily set up or taken down.

It may be found desirable in practice te resort to changes in details of construction and arrangement ofI parts of the invent-ion viiithout departing'fronithe field and scope of the saine, andIV intend toinclude all such appended claim, in this application 'in which 'a preferred forni only ofnijgr invention is 20l With spaced forwardlyprojeatingpins, top
