Richard V. Westover, Lincoln, Nebr.

Application August 5, 1940, Serial No. 351,479

15 Claims.

My invention relates to appliances for stretching and finishing drapery, especially after the drapery ha been cleaned or dyed. Such drapery is usually shortened by the fluids employed in cleaning and dyeing and it remains shortened after drying and it must be lengthened for'use. Then again, it is sometimes desired to fit the drapery to openings which require lengthening of the drapery. My invention is therefore designed for stretching the drapery to the desired length and, then drying the drapery to maintain the length to which it has been stretched.

ne of the objects of my invention is the provision of a stretching device for drapery which has means for the rapid spreading of the drapery until the slack is taken out and having other means for stretching after treatment to soften the fibers of the drapery.

Another object is the provision of a drapery stretcher in which the slack is first taken out of the drapery, the drapery being then treated with steam to soften the fibers, tension being then applied-to stretch the drapery to a pre-determined length, and a current of warm dry air being finally passed over the drapery.

Another object of my invention is the provision of a stretching appliance for drapery, the appliance including clamping bars of novel construction for engaging the drapery at opposite ends thereof and means for spreading apart the bars to stretch the drapery.

Another object is the provision of clamps of novel form for firmly engaging the opposite ends of drapery without wrinkling or otherwise marring the drapery.

Having in view these objects and others which will be pointed out in the following description, I will now refer to the drawings, in which:

Figure 1 is a view in front elevation of my drapery stretcher and finisher, a portion being broken away to disclose otherwise concealed structure.

Figure 2 is a view in side elevation of the device.

Figure 3 is a view in transverse section of the same device.

Figure 4 is a view in perspective showing a detail of the upper clamping member and guideway.

Figure 5 is a sectional view of the detail shown in Figure 4.

Figure 6 is a sectional view showing the detail of the lower clamp in operative position.

showing the clamp in open position and ready to receive the lower edge of the drapery.

Figure 8 is a plan view showing the clamp of Figures 6 and 7 and its operating mechanism.

Figure 9 is a perspective view in section showing the winding mechanism for stretching the drapery.

Figure 10 is an elevational view of a fragment showing the calibrated device for determining the point at which the winding must stop in order to obtain the desired length for the drapery.

The cabinet is elongated and in the rectangular form shown in Figures 1, 2, and 3. All sides are closed except the portion of the front side which is provided with a sliding door or window ID. The opening of the door or window IE] leaves the lower portion of the front exposed in order to give access to the interior of the cabinet for the manipulation of the drapery. The door has secured thereto a strap II which projects on both sides thereof as best shown in Figure 1. Cables l2 are secured to the projecting ends of the strap II and these cables pass over pulleys l3 and M at the sides of the casing. The cables I2 are secured to counter-weights l5 which in the present instance are similar to sash weights employed in window construction. It will be obvious that the sliding door or window I!) may be opened or closed by hand without eifort.

The length of the cabinet is such as to accommodate drapery of the longest length which would be treated in the cabinet. For supporting the drapery in the cabinet there is provided a pair of clamping bars to engage the upper and lower edges of the drapery. For the upper edge of the drapery I employ a bar I6 which is slidable in the guideway I1 and which is provided with clamping members I8 which hold the upper edge of the drapery firmly in place. The bar I6 is grooved at l9 to receive the hem or binding at the edge'of the drapery. Secured to the bar H5 at each end thereof is a member 20 having one portion 2| projecting laterally to slide in the guideway I1 and having an upright projection 22 for the attachment of the cable 23, all of this bein shown in Fi ure 4.

The lower edge of the drapery is secured to the fixed clamp shown in Figures 6, 7, and 8. This clamp remains in fixed position but the two jaws may be opened or closed. One of the jaws has a semi-circular flange while the other has an interfitting semi-circular groove. The drapery can thus be compressed between the two Figure 7 is a view similar to Figure 6 but clamping jaws without injury to the drapery and in such a manner as to leave practically no wrinkles due to the clamp. The clamping jaw 24 is fixed in position but the jaw 25 has pivotal movement about the axis 28. The cam member 2'! on the square shaft 28 is employed for moving the jaw 25 into either the position shown in Figure 6 or in the position shown in Figure '7. In the Figure 7 position the clamp is ready to receive the edge of the drapery while in the Figure 6 position the drapery is firmly secured by the clamp. The square shaft E8 must be turned until the parts are slightly beyond center to provide a lock for preventing the accidental release of the clamp. The square shaft 28 has secured thereto a short lever 23 which may be lengthened for use by means of a short length 33 of pipe. This is done merely because the depth of the cabinet is not sumcient to accommodate a lever of the necessary length.

As before stated, the lower clamp is fixed in position but the upper clamp is movable up and down in the guideway II. The upper clamp bar I6 has cables secured thereto adjacent to its extremities and these cables 23 pass upwardly and over pulleys 3i and St. The cable which passes over the pulley 3i passes also over the pulley 32 and it joins the second cable at 33 from which point the two cables pass as one cable to the winding drum 33. Tension on the cable 33 will thus raise the clamping bar i and the upper portion of the drapery.

Since the initial raising of the upper edges of the drapery should be expedited in order to save time and since the final upward movement of the clamping bar It must be very carefully done, I employ the winding device shown in Figure 9. This device consists of a winding drum 34 loose on a shaft 36 which is provided with a worm gear 3'! to be actuated by a hand wheel 3-8. The shaft 36 has also secured thereto a ratchet wheel 39 with a lever 50 having a pawl 4|. The lever 43 is secured to the drum 3 The desired length of the drapery is determined before other treatment of the drapery. The order may be given by the customer to deliver the drapery in the same length as when the drapery was submitted for treatment. Perhaps, on the other hand, the order may specify a definite length for the drapery when it is delivered to the customer. In the former case it would be necessary to make and note the original length before cleaning or other treatment of the drapery. In the latter case it would be necessary only to provide a proper gauge to obtain the same length as that ordered by the customer. This may be done by the device shown in Figure in which the split tube 42 is calibrated and which is adapted to receive the cable 43 which carries a pointer to register with the calibration of the tube and which carries a weight 44 for maintaining the cable 43 in taut condition. The upper end of the cable 43 is secured within the groove of the pulley 3| so that the cable 43 moves up and down with the cable 23.

By manually turning the crank lever Gil about its axis 36 the drum 34 is turned on the stationary shaft 36 and rapidly winds the cable 23 without disturbing the other mechanisms, reverse rotation of the drum being prevented by the pawl 4!. When it is desired to lower the upper clamping jaws l6l8, all that is necessary is to release the pawl 4| from the ratchet 39 to permit the free unwinding of the cable 23. Slower winding of the cable 23 on the drum 34 may be had through the hand wheel 38 and the worm which is secured to the shaft 36. The rotation of the shaft 323 is communicated through the ratchet wheel and pawl to turn the winding drum 34.

By turning crank 40 which is attached to drum 39 the clamp I6 can be raised quickly almost to the desired ultimate position, preferably to such height that the drapery is pulled straight without being stretched. Further movement of the clamp i6 is effected by turning the hand wheel 38 which by means of the worm gearing, the pawl, and ratchet mechanism causes the cables 23 to be wound up on drum 3! at a slow rate. Accurate adjustment of the final position of clamp I6 is thereby made easy.

In the use of my appliance, the door It] is opened to its Figure 1 position to give access to the interior of the cabinet. The clamp iS-l8 is then lowered until it comes to rest on the angle iron abutments 45 in which position both clamps will be of convenient access for securing the drapery 46 at its upper and lower ends to the clamps i6-i8 and 24-25 respectively. The clamps Iii-i8 may then be raised as previously described, preferably such a height that the drapery is pulled straight without stretching. The application of steam through the forward opening softens the fibers so that the drapery may be stretched by the turning of the hand wheel 33 to the desired length as indicated by the calibration of the tube. The final operation comprises the drying of the drapery while in stretched condition, this being done by closing the door or window Hi and then subjecting the drapery to a current of warm dry air. A suction device draws the air through the conduit to be replaced by air entering the reticulated floor of the cabinet from a conduit 49 having a suitable heating element 56.

Having thus described my invention in such full, clear, and exact terms that its construction and operation will be readily understood by others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patent of the United States is:
