CURTAIN-HOLDING DEVICE.

Application filed July 3, 1922. Serial No. 572,440.-

To all wiiom-it may concern:

Be it known that I, FRANK NEWCOMB, a citizen of the United States, residing at Chicago, in the county of Cook and State 7 I stretchers and dryers of the type used in laundries where a large number of curtains are handled.

One of the objects of my invention is to provide improved means for quickly adjustk ing the frame for curtains of different sizes.

A further object of my invention is to provide improved means for adjusting the "holding bars in which construction one bar will counterbalance the other to adjustment easy. o

A further object of my invention is to provide improved means for securing the curtain on the bar, which will hold the curtain lightly and uniformly at. a great number of points whereby no strain will be placed on any particular part of the curtain, and whereby the curtain will be securely held.

A further. object of my invention is to provide improved means for holding the adjustable curtain holding bars in adjusted position, which can be easily and quickly operated.

Further objects, etc.

In the drawings in which an embodiment of my invention is 'shown- Figure 1 is a side elevational view of an adjustable curtain holding frame mounted to travel on an overhead track into and out of the dryer;

'Fig. 12 is a detail View showing the relation of the holding teeth to the adjustable bar;

Fig. 13 is a section on the line 1313 of Fig. '12;

Fig. 14 is a detail sectional view showing another arrangement of holding teeth.

The construction shown in the drawings comprises a rectangular vertical frame 20 which carries the curtain, provided with rollers 21 mounted to travel on a track 22, whereby it can be easily moved by hand into and out of the drying chamber (not shown). A suitable stop. and holding device 23, (Fig. 1) is provided to hold the frame still while the operator is attaching or removing the curtain.

The frame 20 comprises two vertically adjustable parallel horizontal bars 24.and 25, to which the longer edges of the curtain 26 may be attached, a. fixed bar 26 to which one of the shorter edges of the curtain may be attached, and a laterally adjustable vertical bar 27 to which the other shorter edge of the curtain maybe attached.

The upper horizontal bar 24,is "mounted to slide on a pair of vertical guides 28 and 29 and the lower horizontal bar 25 is m0unt-' "ed to'slide on a pair of vertical guides 30 and 31. Means are provided for'simultaneously adjusting the bars 24 and 25 so that when the upperbar 24 is moved downwardly the lower bar 25 will be moved upwardly and vice versa. These means are constructedso that the weight of one bar will counterbalance the weight of the other bar, whereby in making the adjustment it will not be necessary to lift the weight of the bars, and so that the bars will remain parallel to each ther in their movement.

41 (the pinion 40 meshing on one side with the rack 32 and the other side with the rack 36, and the pinion 41 meshing on one side with the rack 33 and on the other side with the rack 37) and a rotatably mounted tubular shaft 42 on which both of the pinions 40 and 41 are mounted. The slides 34, 35, 38 and 39 are slidably mounted on the vertical guides 28, 29, 30 and 31. The tubular shaft 42 is rotatably mounted in a pair of similar supporting blocks 43 and 44 which in turn are mounted in fixed position on the vertical channel members 45 and 46, which form 'the vertical end members of the rectangular supporting frame 20. The blocks 43 and 44 not only serve as bearings for the shaft 42, but also serve as guides for the racks 32, 33, 36 and 37, to hold them in mesh with the pinions' 40 and 41 respectively. These supporting blocks also serve as a mounting for the vertical guides 28 and 29, and 31 as indicated in Figs. 7

and 8.

with upper and lower rollers 47 and 48 respectively, which engage the upper and lower frame bars 49 and 50 respectively.

The bar 27 is guided and held in vertical position by engagement with the tubular shaft 42 hereinbefore referred to, which carries,

the pinions and 41. This slidable mounting is accomplished by means of a slidable clamp 51 (Figs. 5 and 6) securedto the vertical bars 27, by means of. rivets 52, and a slidable sleeve 53 slidable on the shaft 42 and connected with the bar 27 by means of the diagonally extending braces or arms 54 and 55.

The-clamping member 51 is slidable on the tubular shaft 42, and may be clamped in adjusted position thereon, by means of the hand-lever 56, which has a cam portion 57 engaging a leaf-spring 58 which bears on the channeled clamping block 59, which engages the rotatable tubular shaft 42. The lever 56 is pivotally mounted on a pin 60, mounted in ears 61, on the slide member 62 of the slida-ble clamp. It will be seen that this slidable clamp 51 not only serves to hold the bar 27 in adjusted position on the shaft 42, but also serves to lock the shaft 42 against rotation and thus holds the horithe horizontal bars are the right distance apart, (the counterbalancing of these bars making this operation easy) moving the vertical bar 27 to the desired position, and then throwing the locking member 56 to locking position to hold the vertical bar 27 against longitudinal movement on the shaft 42, and

tation to lock the horizontal bars in ad- "justed position. The bars are then in proper position to receive the curtain.

In order to properly secure the curtains to the bars, it is desirable that they be secured' at a multiplicity of points along the edges, in order that they may be lightly held and without undue stress on the delicate fabric, and in order that they may not be stretched out of shape as would be the case if they were held at only a few points.

It has heretofore been customary to use carding cloth for this purpose. This, however, is quite expensive and I have devised improved means for attaching the curtain as shown in detail in Figs. 10, 11, 12, 13 and 14. In these figures is shown a rectangular frame 63 carrying the parallel horizontal adjustable bars 64 and 65 and vertical parallel adjustable bars 66 and 67. Secured to each of these bars are a plurality, (three as 0 shown) of metal bars or strips 68, 69 and The movable vertical bar 27 is providedcurtain rests, the points of these teeth en-' gaging the curtain lightly, so that the-curtain is held at a multiplicity of points without unduly stretching or stressing any part of the curtain. V
