Application filed October 1, 1914. Serial No. 864,421.

accompanying drawings, forming a part of this specification.

My invention relates to improvements in pattern-setting machines of the general character disclosed in Letters Patent No. 1,063,114, dated May 27, 1913, to which reference may be had. Machines of this general character are employed to wind predetermined lengths of diflerently colored threads or yarns on each spool of a series of removable and replaceable loom spools, in accordance with a pattern or prescribed design, each spool of the series being supplied with threads delivered to it by the patternsetting mechanism, one spool at a time, the threads on each spool corresponding 1n color with the pattern representing one pick of the loom on which the. spools are afterward used in weaving the desired fabric. The threads in being wound upon each spool of any series are drawn from a large number of short bobbins having great lengths of the differently colored threads wound thereon, from which the predeter mined lengths of the threads are out after being wound upon-the loom spool; and the threads are drawn through a suitable spacing and guiding device permanently fixed on the pattern-setting machine. Prior to my invention ortable spacing devices have been employed and while the threads are heldin spaced relation by the permanent spacing device, a portable spacing device has been applied to the threads by a hand operation and afterward removed with each loom spool, as the loom spools are successively supplied with the requisite lengths of threads, the portable spacing devices holding the ends of the spool threads in proper relative position to insure the proper threading thereof into the devices which control the application of the spool threads to the fabric during the weavin thereof.

In the pattern-setting machine of the patent previously referred to, mechanism is employed to automatically stop the rotation of the loom spool when the requisite lengths of threads have been wound thereon, and in other pattern-setting machines no such automatic mechanism is employed and the attendant is required to measure the required lengths of threads and to watch the measured threads'and stop the machine by hand when the measured lengths have been wound upon a loom spool. In either case 1t 1s necessary to applythe portable spacing dGVlCG, While the machine is in motion and the t reads are drawn taut, andalso immediatel prior to and substantially at the same time the machine is to be stopped. Therefore, in the one case where no automatic sto ping mechanism 1s em:

ployed, much di culty has been experienced in properly applying the portable spaclng dwice at the proper time with relation to the stopping of the machine; and, in the other case, where the machine is automatically stopped, it has been'equally diificult to time the application of the portable spacing device, because the attendant has no means of accurately determining just when the automatic stopping mechanism' would come into action.

The object of my present invention is to remedy the deficiency and overcome the difliculty previously mentioned; and I accomplish my object by the combination with a pattern-setting machine having, as generallystated, a means operative to stop the rotation of a loom spool therein after the requisite lengths of threads have been 'wound thereon of a spacing device and of means controlled by the first named means operating to automatically apply such spacing device to the threads being wound upon the loom spool, and including also, in a preferred combination of means to automatically stop the rotation of a loom spool and to automatically apply a portable spacing device to the threads being wound upon the logm spool, in a .certain relation to each ot er.

With these objects in view, my invented a plan view of the machine, partly bro lienaway. Fig. 3 is a vertical section through' the machine, on line 3-3 of Fig. 2. "Fig. 4. is a vertical section through parts of the machine, on line 44 of Fig. 2, showing the carriage for the portable spacing device and the .actuating devices, the carriage being shown in the lower or inoperative position. Fig. 5 is'aview of the parts shown in Fig. 4, the carriage being in the raised or operative position. Figs. 6 and 7 are vertical sections on lines-6-6 and 7?7, of Figs. 4

and 5, respectively showing different relative positions of the permanent and portable spacing devices. Fig. 8 is a view of the portable spacing device, enlarged. Fig. 7

9 is azview of the thread retaining bar for the portable spacingdevice. Fig. 10' is a view ofa filled loom spool removed from the pattern-setting machine and having the portable spacing device applied thereto.

Referring to the drawing, 2 designates the framed the machine, 13 a loom spool supported within themachine, and 77 the horizontal bar over which the threads are drawn while being wound upon the spool '13. The bar 77 is provided with suitably spaced upwardly projecting pins 78 between which the threads are drawn and which iao relatively to each other. The spool 13'is serve to maintain the threads evenly spaced detachably supported by, between and in axial alinementwith two short shafts 9 and 10; and the shafts 9 and 10 and therewith the spool 13 is rotated from the main driving shaft 28 as follows: Secured to the main shaft 28 is a pinion 29' co-acting with a gear wheel 30 which is loosely "mounted on a supplemental shaft 31. The gear wheel 30 is adapted to be clutched to and unclutched from the supplemental shaft 31 as will be hereinafter described. The shaft 31 is provided with gear wheels 32 and 33 co-acting with idlers 34 and 35 which coact with gear wheels 36 and 37 secured to the shafts 9 and 10, respectively. It will thus be seen that the spool 13 may be rotated'from the main shaft 28 when the gear wheel 30 is clutched to the supplemental shaft 31.

The main driving shaft 28 is provided with three pulleys 38, 39 and 40. The outer pulleys 38 and 40 are loose on the shaft 28 and the intermediate pulley 39 is fixed on the shaft28. The loose pulley 38 is driven by a direct belt 41 from a pulley 42 on a power shaft 43 which is suitably mounted The gear wheel 30 is clutched to and unclgtched from the shaft 31 by'a clutch collar 61 which is splined on the shaft 31 and is provided with projecting teeth adapted to co-act with teeth projecting from the hub of the gear wheel 30. The clutch collar 61 -is held normally disengaged from the gear wheel 30 by a spring 62; and the collar 61 has a circumferential groove 64 into which pins project from arms 65 which extend from a horizontal rock shaft 66. The shaft 66 is provided with an arm 67 having a projection 68 which rests upon a cam 69 one 'cam shaft 70. The cam shaft 70 isprovided with a worm wheel 71 which is engaged and driven by a' worm 72 on the shaft 31. The projection 68 is pressed against the cam 69 by the action of the spring 62 in tending to move the clutch collar 61 away from the gear wheel 30 so that the cam 69 mayhold the clutch collar 61 in engagement with the gear wheel 30 until a notch 73 in the cam 69 comes into registry with the projection 68, when the projection 68 will enter the notch 73 and the spring .62 will move the collar 61 to unclutch the gear wheel 30 from the shaft 31 and thereby automatically stop the rotation of the shaft 31 and the spool supporting shafts and 10 geared therewith.

The rock shaft 66 and therewith the arms 65 and 67 may be moved by hand levers 76 connected by a bar which is connected to an arm 74 projecting from the rock shaft 66; and when it is desired to start the rotation of the spool 13 to wind the threads thereon, the arm 67 is raised by hand to move the projection 68 from the notch 73, thereby clutching the gear wheel 30 to the shaft 31. After the worm 72 has started the rotation of the cam 69, the arm 67 is released and the spring 62 presses the pro-- jection 68 against the cam 69 until the de sired predetermined lengths of threads have been woundupon the spool 13, when the notch 73 comes into registry with the projection 68 and automatically stops the spool 13, as previously explained.

Thus far the construction and operation of the machine isthe same as that shown and described in Patent No. 1,063,114 hereinbefore referred to. The horizontal bar 77 and its upwardly projecting pins 78 constitute the thread spacing and guiding device which is permanently fixed on the machine.

Arranged adjacent to the bar 7 7 is a carriage 5 adapted to receive the portable spacing device 8 for the threads. The carriage 5 comprises a long frame or bar having a groove in the top thereof for the reception of the portable spacing device 8; and the carriage 5 is held against the vertical face of a bar 11 ofthe machine frame by bolts 12 which extend through vertical slots 14- in the bar 11 and permit the. carriage to be raised from an inoperative position shown in. Figs. 4 and 6 to an operative po-' sition shown in Figs. 5 and 7, andlowered.

5 is down, or in the inoperative position, the

teeth 15 are below the top of the bar 77. on the path of travel of the threads being wound upon the' spool 13. Therefore, when the carriag 5 is raised to the operative position shown in Fig. 4, the teeth 15 will pass between the threads extending over the bar 77 and maintain them properly spaced from each other.

Directly beneath the carriage 5 is a pair of parallel levers 16 which are fulcrumed, at 17 on the bar 11. The lower ends of the levers 16 are connected by a link or bar 18 which, when moved to the position shown in Fig. 5 will cause the upper ends of the levers 16 to engage the bottom of the carriage 5 and raise it tothe operative position, and which, when moved to the position shown in Fig. 4 will lower the carriage 5 to the inoperative position. The bar 18 is connected to one end of a spring 19, the other end of which is connected to the bar 11 and the spring 19 is arranged to move the bar 18 and therewiththe levers 16 from the position shown in Fig. 4 to the position shown in Fig. 5. The bar 18 and levers 16 are maintained in the position shown in Fig. 4, against the action of the spring 19 by a latchrod 20 connected to one end of the bar 18 and having a'shoulder 21 formed thereon and engaging a suitable stop 22 formed on a bracket 23 which forms a part of machine frame. When. the parts are in position shown in Fig. 4, the spring 19-presses the shoulder 21 against the stop 22; and, therefore, it will be understood that if the shoulder 21 be raised from the stop 22 the spring 19 will move the bar 18 and'levers 16 to the position shown in Fig. 5 and thereby raise the carriage 5 and therewith the portable spacer 8 to the operative position. Directly beneath the rod 20 is a pin or stud 24 which projects from an arm 25 which is pivoted, at 26, to a bracket 27 on the machine frame and rests normally upon a projection 46 on the machine frame. The arm is' provided with a vertically adjnstable plate 47 secured thereto by suitable screws 48, and beneath the plate 47 is a pin or stud 49 projecting from an arm 50 which is secured to and extends from a shaft 51, as clearly shown in Figs. 4 and 5.

The shaft 51 is mounted to turn suitable bear'ings on the machine frame and it. extends beneath the supplemental'shaft 31 previously referred 'to. The shaft 51 is pro;

vided with a worm wheel 52 which co-acts with a worm 53 on the shaft 3l, whereby, when the gear wheel 30 is clutched to, the shaft 31 and'.the shaft 28 is rotated, the

shaft 51 will be rotated at a. slow rate of speed. The arm 50 and pin'49 are so related to the plate 47 on the arm 25 that,when-the shaft 51 is turned, after the parts havebeen set in the position shown in Fig. 4, the pin 49 will raise the arm 25, thereby causing the pin 24 to raise the rod 20 and its shoulder 21 from the stop 22 and thus permit the.

spring 19 to raise the carriage 5 to the operative position. The turning movement of the cam 69 and the arm 25 relatively to each other is such that the arm 25 will automatically efiect the raising of the carriage 5 to the operative position immediately prior to the cam notch 73 coming into registry with the projection 68 on the arm 67 to automatically stop the rotationof the spool 13. v Thus the teeth 15 of theportable spacer 8 will be raised into the spaces between the threads being wound upon the spood 13 while the threads are drawn taut and the spaces between them are in exact registry with the teeth 15 of the portable spacer.

After the carriage 5 and the spacer 8 thereon have been raise operative position, shown inFigsf5 and 7, and the rotation of the spool 13 has been stopped, a thread retaining bar 55, U-shaped in cross section, is placed-over the teeth 15 of the spacer 8 to hold the threads in place therein, and the bar 55 is held in place by suitable clips 56 on the spacer 8 and adapted to engage the bar 55. The spool 13 is then removed from the shafts 9 and 10 and moved up to the spacer 8 as the spool is turned by hand to wind upon the spool the short lengths of thread ortable to the v extending between the spool 13 and the spacer 8. The portable spacer 8is then removed from the carriage 5 and secured to the spool 13 by means of short springs 57, onel'at'each end of the spacer, one end of each spring is attached to the spacer 8 and the other end of each spring is attached to an end pin on the spool 13, as shown. An empty spool 13 is now inserted between the shafts 9 and 10 and the previously wound spool is moved back, drawing the threads extending therefrom over the empty spool. The threads are then secured to the empty spool and the short-lengths of threads extending between the empty spool and the portable spacer attached to the filled spool are severed by a suitable cutter such as a pair of scissors and the filled spool with its portable spacer is removed from the ma now supported between the shafts 9 and 10,

the attendant moves the rod 20-inwardly to lower the carriage 5 to theinoperative position shown in Fig. 4, andplaces a portable spacing device 8 within the groove in the carriage 5. If the arm 50 has not moved to lower the arm sufficiently to permit the shoulder 21 to be engaged with the stop 22 when the attendant lowers the carriage 5, the attendant may engage the shoulder 21 with another stop 58 on the'bracket 23 and engage the shoulder 21 with the stop 22 after the arm 25 has been lowered upon the support 46, whereupon the mechanism for automatically raising the carriage 5will be in position for a succeeding operation.
