MACHINE FOR TRIIVHVIING ND APPLYING SHADE GOODS.

SPECIFICATION 'Ormng'part of Letters Patent N o. '754,7 59, dated Algrlclil Si, i

Application led May l2, 1903. Serial No. 156,766. (No model.)

To all whom, t may concern:

Be it known that I, EPHRAIM O. ENGBERG, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and lmproved Machine for Trimming and Applying Shade Goods, of which the following is a full, clear, and exact description.

This invention relates to amachine by which the fabric used for window-shades may be conveniently and accurately slit at its edges to produce the proper width and severed into the necessary lengths, the machine simultaneously creasing' the stock, so as tofacilitate the application to the lower edge thereofl of the usual p slat, and the machine, further, having means for carrying the shade-roller and for rotating the same during the operation of the machine, whereby automatically to wind the shade on the roller.

This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the invention. Fig. 2is aplan view thereof. Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2. Fig. 4 is a cross-section on the line 4 4 of Fig. 3. Figs. 5 and 6 are enlarged sectional views of the creasing devices. Fig. 7 is a View showing the manner of folding the end of the stock. Fig. 8 is a sectional detail showing the device for mounting the shade-roller in the machine, and Fig. 9 is an enlarged plan view of a pair of the slitting-knives.

The machine should be provided with a suitable framing, the details of which will not be described. l

10 indicates the primary-movement shaft, which is provided with any suitable means for driving it. According to the organism of the hand-machine here illustrated said 'shaft is provided with a crank 1 1. This shaft is mounted transversely in the frame and is connected by gears 12 with a shaft 14,V which runs pai-,

alle] therewith innnediately below it. A transverse guide 15 1s mounted in the frame, and said guide carries two brackets 16, which are adjustable on the guide by means of screws 17 or the like. Each bracket 16 has two arms, one projecting to the plane of the shaft 10 and the other arm to the plane of the shaft 14 and each being provided with sleeves 18, in which are fitted to turn the hubs 19 of rotary knives 20, said hubs having feathers or keys thereon, which run in corresponding keyways in the shafts 1() and 14, as best shown in Fig. 9. 21 indicates springs bearing between the collars 18 and knives 20 and serving to press said knives into engagement with each other, the knives overlapping, so that the goods when drawn between them in the manner illustrated in Figs. 2 and 3 will be trimmed. The rotation of the shafts 10 and 14 imparts a corresponding movement to the knives. By adjusting the brackets 16 on the guide 15 the machine may be accommodated to any width of stock. The said primary-movement shaft 10 carries a pinion 22, and said pinion is in mesh with a gear 23'in connection witharoller 24, extending transversely in the frame. Over this roller the stock is passed from the roll 25, on which said stock is wound, the roll 25 being mounted loosely in the frame, as shown best in Fig. 3.

26 indicates a friction-roll,which is mounted in swinging arms 27, and said arms are under the tension of springs 28, thus moving the roll 26 tohold the stock between said roll and the roll 24, and thereby giving the roll 24 sufficient hold on the stock to enable it to be drawn from the roll 25. Said roll 26 also serves to bring the stock down into the plane of the meeting edges of the knives 20.

In suitable vertically-disposed guides on the frame is mounted to move vertically a horizontal cross-head 29, this cross-head carrying ixedly a creasing-blade 30 and having a longitudinal cavity 31 therein in which is loosely arranged a second creasing-blade 32. As best shown in Fig. 4, the blade 32 is connected at its ends with downwardly-extending rods 33, passing loosely through a treadle 34 and having nuts or other stops 35 at their lower extremities. Springs 36 are arranged to act between the blade 32 and the cross-head 29 and serve to hold said blade yieldingly in the position shown in Fig. 5. The cross-head is connected at each end to a downwardly-extending TOO rod 37, in which rod springs 38 are interposed, these springs being either fastened to or formed integral with the rods and said rods being securely connected at their ends with the aforesaid treadle 34.

rlhe rods

33 and 37 pass loosely through guide-lugs on the frame, as shown best in Figs. 3, 5, and 6, and immediately above these guide-lugs is arranged a rocking creaser-bar 39. At one side of said bar is a rigid strip 40, carried by the frame and extending transversely thereof, and at the other side of the creaser-bar 39 is a wall 41, which is mounted on the frame to swing toward and from the bar 39. Between the bar 39 and the said lug of the frame an expansive spring 42 is arranged, this spring tending to throw up the cross-head 29. The normal position of the parts therefore is then as shown in Fig. 5, and when the treadle 34 is depressed the

parts

29 and 32 move down bodily until the blade 30 enters between the strip 40 and the creaser-bar 39. Then the movement of the cross-head ceases, the springs 38 give, and as the treadle 34 strikes the nuts 35 the blade 32 moves down independently of the crossA head and enters between the creaser-bar 39 and the wall 41, either of the blades 3() and 32 forming a crease in the stock, as indicated in Fig. 6. Cams 44 are mounted on a rocking shaft 45 and arranged to bear against the swinging wall 41. Said shaft 45, as best shown in Fig. 1, is provided outside the frame with a handle 46, which permits the manual rocking of the shafts. The cams 44 are normally in the position shown in Figs. 5 and 6, and when the parts assume the position shown in Fig. 6 the shaft 45 should be rocked to throw the cams 44 against the swinging wall 4f and rock said wall toward the creaser-bar 39, thus imparting a like rocking movement to said bar and bringing all the other of `the

parts

39, 40, and 41 up snugly together, thereby finishing the creases, the formation of which was started by the above-described action of the

blades

30 and 32. The strip 4() is preferably provided with a longitudinal groove in its upper edge, and said groove is intended to guide a hand cutting-tool, indicated bythe broken lines 47, (see Fig. 6,) this tool being run over the strip 40 to sever the stock when the parts assume the position shown in Fig. 6.

On the drive-shaft 10 is a pulley 48, and over this pulley runs a belt 49, said belt also `.passing over a pulley 50, formed on or fastened to a sleeve 51, arranged to turn freely in a bearing 52, mounted on the end of a transverse guide 53, itself suitably fastened to the frame. (See Fig. 8.) Said sleeve 51 has an angular interior, in which fits acorrespondingly angular shaft 54, this shaft sliding in the sleeve, but turning therewith and having at its inner end a head 55, turning loosely in a bearing 56, adjustable longitudinally on the aforesaid guide 53.

Said head 55 is provided with a central orifice 57, receiving the journal 58 ofa shade-roller 59, which roller forms no part or my invention, but may be any of the well-known commercial shade-rollers. The head 55 is also provided with one or more prongs 60, which engage with the roller to impart rotary movement thereto. The opposite end of the shade-roller, as shown best in Fig. 2, is mounted in a suitable bearing 61, adjustably held in the guide 53. By this mechanism the

bearings

56 and 61 may be adjusted toward and from each other to seat any length of shade-roller which it is desired to employ, and by means of the belt 49 and its

pulleys

48 and 50 the said shade-roller will be rotated in time with the other machine-controlled movements of the apparatus.

In using the invention the stock is wound on the roller 25 and then led through the machine, as shown in Fig. 3. The leading edge of the stock should then be fastened to the shade-roller in the usual manner and the rotating parts of the machine started, thus simultaneously trimming o the stock to the desired width and winding the same on the shade-roller. When the necessary amount of stock has been wound on the roller, the treadle 34 should be depressed, thus throwing the creaser-blades into the position shown in Fig. 6 and clamping the stock between the

parts

29 and 39. The before-referred-to hand-tool 47 should now be manipulated to cut off the stock and then the cams 44 operated to throw the wall 41 up and finish the creasing opera# tion. After this has been done the treadle should be released and the creasing devices allowed to return to their inactive position. It will be observed that this operation forms two creases in the end of the stock. This facilitates the ready folding of the stock in the' manner shown in Fig. 7, after which it is stitched along the broken line, (indicated at L in Fig. 7 ,l and theusual slatshould be slipped through the socket thus formed. This finishes the operation on one curtain, and the second operation is begun by placing a new roller in the machine and leading the severed edge of the stock forward into engagement with the roller, as before described.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.
