Application September 22, 1952, Serial No. 310,855

12 Claims. (Cl. 34-151) The present invention relates to a device for stretching and shaping various drapery and curtain materials and more particularly pertains to a device of the above character which will restore and rejuvenate various drapery and curtain materials, particularly those materials which have been subjected to repeated phases of dry cleaning.

These various materials after repeated dry cleanings, lose their original length and sheen. This invention is therefore designed to restore these various drapery and curtain materials to their original length and to revive their original sheen or iinish, or in the case of new materials, to maintain their original lengths and finishes.

One of the objects of this invention is to provide a exible stretching mechanism to accommodate any length of drapery or curtain, and any number of panels of drapery or curtains of the same materials, so that the stretching mechanism can maintain an even tension on the fibers of the materials during the entire process of returning the materials to their original length, Or of increasing this tension as the requirements of each and every material might dictate to produce the desired result.

Another object of this invention is to provide a table over which the required number of drapery or curtain panels may be suspended during the relaxing of the fibers of the shrunken materials and the resetting of the same fibers after their original lengths are arrived at. Also, it is an object of the invention to build into this table the means of relaxing these bers and to provide means also built into the table for resetting these fibers after the same have been relaxed and brought to their required length.

Another object of this invention is to provide a means of clamping and holding these various draperies without injury to the materials, which clamps are to provide a means of pressing into the draperies the necessary pleats that occur at the heads of all drapery or curtain panels.

Yet another object of this invention is to completely finish the drapery or curtain to the required dimensions.

These, together with various ancillary objects and features which will become apparent as the following description proceeds, are attained by this invention, a preierred embodiment of which is shown by way of example in the accompanying drawings, wherein:

Figure l is a top elevational View of apparatus embodying the present invention with certain parts being broken away for clarity of detail;

Figure 2 is a side elevation of the apparatus substantially along section line 2 2 of Figure l;

Figure 3 is a sectional view of the apparatus along section line 3-3 of Figure l;

Figure 4 is a sectional View of the apparatus taken substantially along section line 4-4 of Figure l; and

Figure 5 is a sectional View on an enlarged scale of a portion of the table of the apparatus, being taken along section line 5 5 of Figure 2.

Referring now to the accompanying drawings in detaken taken tail, it will be noted that like reference numerals are utilized to designate like parts throughout the various views.

The apparatus comprises generally a rectangular frame 10 consisting of side frame members 12 and 14, end frame members 16 and 18 and legs Z0. The side and end frame members are preferably constructed of aluminum and are of generally channel shape. The legs 20 are also preferably constructed of aluminum and, in the preferred embodiment shown, are of angular shape. However, it is to be noted that other structural shapes and materials may be used without departing from the spirit of the invention. It will be noted however, that the end frame member 18 is specially constructed to form a deep channel having an elongated upper flange overlying a portion of the side frame members 12 and 14 to form an air plenum 22 for a purpose that will become later apparent.

Within the confines of the frame 10 and slanting upwardly from end frame member 18 to end frame member 16 is a table, which table supports steam coil 26. Secured at its peripheral edges to the table 24 is a covering 28 which covers the steam coil 26. Steam enters the steam coil 26 from the steam header 30, which header is connected with the coil 28 via flexible coupling 32. Steam entering the coil 26 from the header 30 passes through the coil and out a condensate header 34 at the lower end of the coil. Steam jets 36 are secured in the steam coil 26 at spaced intervals therealong to send concentrated streams of live steam into the covering 28, which covering disseminates the steam upwardly within the contines of the frame 10. As will be noted particularly from Figure 5, the covering 28 for the steam coil 26 comprises a copper screen 38, padding 40 and a removable covering 42 in order to thoroughly disseminate steam from the coil 26.

Mounted centrally of the lower flange of the end frame member 18 is a blower housing 44 in which a blower (not shown) is housed for blowing air into and through the air plenum 22 and over the covering 28 of the steam coil.

On the frame 1t) extending between the side frame members 12 and 14 are mounted a stationary clamp 46, adjustable longitudinally of the frame members, and a movable clamp 48, the adjustable clamp being adapted to remain in its relatively adjusted position while a stretching mechanism 50 is provided for shifting the movable clamp 4S, with respect to the stationary clamp in its adjusted position.

Each of the clamps 46 and 48 may comprise a pair of elongated blocks or members 52, 54 and 56, 58 respectively, the blocks of each clamp being juxtaposed upon another with the blocks 52 and 56 comprising the upper blocks and the blocks 54 and 58 comprising the lower blocks of each clamp 46 and 48 respectively. Mounted on the lower surface of each of the blocks 52 and 56 is a resilient pad 60, preferably of crude rubber. The upper surfaces of the blocks 54 and 58 are grooved or serrated as at 62 and the upper pieces or blocks 52 and 56 are cambered so that when the upper end lower blocks are pressed toward one another a compression space between the two blocks will be provided to take up the unevenness of the thickness of materials to be processed on the apparatus.

To adjustably mount the stationary clamp 46, the side frame members 12 and 14 are longitudinally slotted as at 64 adjacent the end frame member 1S. Rods 66 extend through the slots 64 and are spring loaded at their lower ends as at 63 so that the tendency will be for these rods to be pulled downwardly through the slots 64. The upper end of each rod 66 is formed as a flat plate 70 which overlies an end of the block 54 and thereby frictionally clamps this block against the side frame members 12 andq 14". upst'andng n'ger grip 72 is" provided" on th'e tiat plate 70 whereby whenit is desired to move the stationary clamp 4,6, the rod 66 can be pulled upwardly and thek ciampi 46 s'lidintol the desired position. torn of the`blck`54`tis secured one end of a` liexible cover 74, the other end` of which isfwound on a spring loaded rollerV 76 secured' to the endV frame member 18. Thus, as the cla'mp` 4'6' is adjusted the exible strip 74 will be moved therewith thereby providing, in combination with the end'fr'ame member 18, an air duct for channelizing the ow of air from the blower housing 44 through the air plenum 22"tol between the clamps 46 and 48.

A's will`be particularly apparent from Figures l and 3, the lower blocks of the clamps 46 and 48 are longer than the upper blocks and have their ends extending beyond the endsof the upper blocks to facilitate the mounting of a locking" means to'lock the top and bottom blocks or members ofea'ch clamp together under the desired tension required to suit the various materials to be clamped therebetween. Referring particularly to Figure 3, this locking means willbe readily observed. Mounted on the ends of the bottom block or member 58 of the clamp 48 are a pair of upstanding threaded rods 78. Mounted on the upper surface of the block 56 at the ends thereot` are horizontally extending plates 80 which extend beyond the ends of the block 56 and through which the upper portions of the threaded rods 78 extend in order to secure the upper and lower blocks 56 and 58 in vertical alignment. Threaded on the upper ends of the rods 78 are collars 82 and pivotally secured to these collars 82- are cam levers 84 formed with cam surfaces 86adjacent their pivoted connections to the collars 82. The free ends of the levers S4 are provided with flat extensions 88 providing handles for pivoting the levers about the collars 84. ln operation, the collars 82 are threaded on the rods 78 a desired distance and the levers 84 are pivoted to a horizontal position whereby the cam surfaces 86 frictionally engage'the plates 80 and clamp the upper bar 56 to the lower bar 58. Although the above description has beenmadewith reference to the clamp 48, it is to be noted that the same locking means is provided forthe clamp 46.

Secured at one end to the lower portion of each of the rods 66 holding the stationary clamp 46 in place is a tape measure 90, the other end of which is Wound in a-case 92 mounted on the end'frame member 16. lt is to be noted' that the tapel measure 90 is spring: wound within'the casing 92 whereby as each rod 66 is moved to an'a'djustedfposition, the tape 90 will remain under tension.

To slidingly and guidingly mount the movable clamp 48 on the frame 10, the side frame members 12 and 14 are provided with guide rails 94. Yokes 96 mounted on the surface at the endsof the lower block 58 embrace these guide rails so that the clamp 48 can be moved longitudinally therealong.

The stretching mechanism which comprises the means for sliding the clamp 48 along the guide rails 94 comprises aishaft` or rod 98 journaled through the center of the end frame member 16 and extending axially between the sideframe members 12 and 14. Between the end framemember- 1'6I and the movable clamp 48 is an elongated bar 100,- the ends of which are slidably mounted on the guide rails 94 in the same manner as is clamp 48. The portion of the rod 98 disposed between the clamp 48 and the bar 100 is provided with both right and left hand threaded sections as indicated by the numerals 102 and 104 respectively. A collar 106 is threaded on right hand threaded section 102 and a collar 108 isV threaded on left hand section 104. Secured to opposite sides of thel collars 106 and 108 are sets of scissored levers 110 and' 1'12 respectively. Trackways 114 and 116 are secured tothe. elongated ybar 100 and the To the boty bottom member 58 of the movable clamp 48. Rollers 118 secured to the' other ends of each set of4 sci'ssore'd levers and 112 are guidingly disposed in these tracks or guideways 114 and 116. Thus, upon actuation of the handwheel 120 rotating the shaft 98, the clamp 48 and the elongated bar 100 are moved toward and away from one another.

However, in order to prevent the movement of the elongated bar 100, channel brackets 122 are secured to the ends thereof and cam levers 124 are pivoted between the flanges of these channel brackets to frictionally contact the guide rails 94 and thereby firmly secure thte bar against movement.

In operation, the clamps 46 and 48 are first placed in their desired popsitions and a panel of drapery or curtain material 126 is clamped between the blocks of these clamps. Steam is introduced into the steam coil 26 and passesvthrough the jets 36 under pressure and is disseminated up between the clamping blocks 46 and 48 to saturate the fibers of the drapery or curtain material 126. Then the elongated bar 100 is locked in place and pivoting the camming levers 124 to a horizontal position, and the handwheel 122 is turned moving the movable clamping form 48 toward the end frame member 16 and thus stretching the material to the desired length as indicated by the measurement on the tapes 90. When the drapery material 126 is stretched to its desired length, the steam pressure is cut olf from the steam coil 2'6 and the blower in the blower housing 44 is then turned onto direct a flow of dry air through the air plenum 22 underneath the drapery material 126 to dry the fibers of the same. When the drapery material 126 is completely dried, it is removed from the frame restored to its desired length. Then, the apparatus, which includes the table 24 and the frame 10 may be pivoted up out of Hoor engaging position by virtue of the tiexible couplings connecting the steam header to the steam coil.

From the foregoing description, the operation of the device is believed to be clearly understood and further description is believed unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after a perusal of the foregoing specification taken in conjunction with the accompanying drawings, it is not desired to limit the invention to the exact construction shown and described; but, all suitable modiications and changes may be resorted to which fall within the scope of the appended claims.
