Claims.

The present machine relates to the handling and separation of textile pieces sewed together and brought to the machine on reels. The pieces are generally from 50 to 70 yards and the total length of the multiple pieces seamed together is generally from 300 to 400 yards. The function of the machine is to wind the textile in suitable lengths on a paper tube ready for delivery to a customer and a specic length may be that of a single piece or a plurality of pieces. The Winding operation is effected at high speed and the object of the present improvement is toprovide means for stopping the machine to bring the seam join- Y., ing separate pieces into a predetermined convenient position for cutting the seam and making ready a succeeding piece for winding, Without imposing shock and undue strains upon the highspeed rotating members or the textile piece, notwithstanding the fact that the rotational elements of the machine are under a high degree of momentum when the stopping devices are applied. Further objects will hereinafter appear.

The invention will be described with reference to the accompanying drawings, in which:

425 Figure 1 is a front elevation of an embodiment of the invention.

Figure 2 is an end elevation, taken from the motor end.

Figure 3 is an enlarged elevation, partly in lon- 30 gitudinal section, showing the automatic seamoperated switch mechanism.

Figure 4 is a plan View of the structure shown in Figure 3.

Figure 5 is a vertical section on the line 5-5, Figure 3.

Figure 6 is a schematic wiring plan.

Referring to the drawings, I have shown at I, Irc, opposed heavy vertical frame members connected by the tie-rods 2. Each frame member carries an inwardly projecting axle 3 upon which is mounted one of the two opposed swing-brackets 4, each bracket being provided with three bearing members so that upper bearing members 4:1: are provided for the shaft 5 of a drum 6, intermediate bearing members 41:1: are provided for the shaft 'I of a guide roller 8, and lowermost bearing members 4mm are provided for the shaft 9 which carries the guide roller IIJ.

The supply drum II, Figure 2, is rotationally 50 carried by any suitable means supported by bracket such as I2 and the fabric is lead from the supply drum (as shown by the dotted lines t, Figure 2) over roller I0 under guide roller 8, thence partially around drum Ii, the textile being held down upon the drum by a pressure roller I3 carried by suitable arms such as I4 pivoted at I5. The textile then extends to and over a guide roller I6 on a shaft I'I and directly to the paper tube indicated by dotted lines p, Figure l, the tube lbeing held by pintles I8 having sleeves |89: on stud 5 shafts I9. While the pintles I8 are retractable with the sleeves which carry them, these sleeves Will be suitably keyed to shafts I9 so that rotation of the shafts will impart rotation to the tube p. The textile is pulled from the supply drum by l0 rotation of the paper tube through positive rotation of stud shafts I9. For such purpose the end of each stud shaft is given rm bearing support Within Aa housing carried by the frame member I or frame member Ix, as the case may l5' be, and each shaft 'I3 carries a sprocket Wheel (not shown) over which is led a chain, one of the chains b-eing indicated in Figure 2 at 2l. Each chain is led over an idler sprocket Wheel such as 22, Figure 2, and thence over a drive sprocket 20 such as indicated at 23, Figure 2, the drive sprocket being on a shaft 24, one .end of the shaft projecting outwardly from the frame member Irc and carrying a pulley adapted to be clutched to shaft 24 by the endwise movable clutch 'mem- 25 ber 26. 'I'he pulley 25 is driven by a belt 21 from a drive pulley 28 on the shaft of a motor 29.

A'clutch operating lever 30 is pivoted at 3I on a suitable bracket carried by the frame member Ia: and is normally held against a stop pin 32, 30 Figure 2. To the clutch operating lever is secured a link 33 `connected to the lower end of a rock arm 34 pivoted at 35 (Figure 1) on a bracket plate 36. The pivot member for rock arm 34 is a shaft to Which the rock arm is secured, and carried by 35 the shaft is a foot-operating lever 3l having two foot pedals, i. e., pedals 31:1: and 31mm. When pedal 31m: is depressed, rod 33 will be moved to the left from its position shown in Figure l and the clutch will'be operated to rotate drive shaft 40 24. As pedal 31m: is depressed, .a latch hook 38 will snap over a latch linger 39 and thus the clutch will be held in operative position. Latch hook 38 is pivoted at 38a: and normally held in the position of Figure 1 by a spring 4I). 45

The relation of latch hook 38 and latch linger 39 is such that depression of pedal 31m will cause disengagement of the latch hook from. the linger; also positive movement of the latch hook to the right from its position in Figure 1 will ef- `50 fect release of the latch linger. In the cycle of operation, such a releasing movement of the latch hook is effected by a solenoid, the solenoid winding being Adisposed in box 4I and the core 42 being pivoted to the latch hook at 43.. 15

By reference to Figure 2, it will be seen that the supply drum for the seamed textile pieces carries a small brake drum Ila: disposed between two brake levers 44 normally engaging the brake drum I I through the action of a spring 44x but held out of braking relation with the drum through the action of a solenoid 45. When a circuit through the solenoid, later to be described, is broken the brake is released and comes into action. Any suitable operating connections between solenoid 45 and the brake levers 44 may be employed and hence I have not shown such connection in detail.

By reference to Figures 1 and 2 it will be seen that one of the two positively driven shafts I9, i. e., that affording a bearing support upon frame member Ix, carries apulley 46 which drives a belt 41 which rotates a pulley 48 carried by a governor shaft 49. On the shaft is mounted a usual type of ball governor 50 which, when the machine is at rest, depresses the rear end of switch lever I, carrying its contact point out of engagement with the contact point of a switch finger 52. Switch lever 5I receives current via wire a and switch finger 52 receives current via wire b. As the fabric passes from guide-roller i9 to drum 6, it passes over a smooth-surfaced disk 53 best shown in Figures 3 and 5. This disk is held on the upper end of a vertically movable rod 54 and is carried by a bearing member 55 within a switch box 56, the lower insulated end of the rod engaging a spring switch arm 51 having a contact on its lower face and in register with a similarly formed switch finger 58. Above the textile sheet and in contact therewith, is a second smooth-faced disk 59 carried by a threaded shaft 60 which is threaded in an aperture formed in a bracket arm 6I. On the upper end of threaded shaft 60 is a dial-surfaced thumb piece 60:6, and a pointer 62 is carried by bracket arm 6I.

It is intended that the thickened line caused by the seam joining two textile pieces will close the switch comprising members 5l and 58 and therefore contact disk 59 is held in adjusted, but fixed, position, and disk 53 with its rod 54 will be moved downwardly a distance equivalent to the thickness of the seam. If the thickness of the seam is insufficient to bring the kswitch contacts together, rotation of thumb disk 33a: may be had to move switch arm 51 closer to its co-acting member 58 and the dial and pointer will at all times indicate the distance between the switch contacts.

A brake is provided for drum 6. To this lend the drum shaft 5 carries a brake pulley 62 over which passes a brake band` 63, one end of the band being held by a yoke 54 supported from frame member Im and the opposite end of the band being connected at 55 to the core of a solenoid or brake magnet BM.

In the operation of the machine, the textile is led from the supply reel over guide roller Il) and thence between the disks 53 and 59 of the feeler switch mechanism, thence around the surface of drum 6 to guide roller I6 and thence to the paper tube p. Pedal 31x is then depressed until finger 33 is engaged by latch hook 38, and rod 33 will be moved to the left from its position in Figure l, causing the clutch to engage, thus rotating shaft 24 and, through drive chains 2I effecting rotation of stud shafts I9 and the paper tube p. When a seam meets disk 53, rod 54 will will be depressed and the feeler switch comprising members 5l and 5.8 will close a circuit through the clutch magnet or solenoid 4I, pulling latch hook 38 clear of the finger 39, whereupon rod 33 will move to the position of Figure 1 under the influence of the clutch-releasing spring (not shown) and the power rotation of shaft 24 will be stopped. As the clutch is released, rock arm 34 will be moved to the position of Figure 1 and through its connection with a link 66, which is, in turn, connected to a lever arm 6l, a mercury switch A will be moved to the position of Figures 1 and 6, closing a circuit leading through the brake magnet BM, thus operat'- ing the band brake member 63 to stop the momentum of drum 6. The said circuit comprises a positive wire d, branch wires e, e', the brake magnet BM, return wire f, mercury switch A, governor switch wire b, the governor switch and return wire a. Inasmuch as declutching shaft 24 from the power drive will not, of itself, stop rotation of the machine elements, this continued rotation will keep ropen the governor switch until the circuit is completed through the brake member for the drum. When the machine is brought to `a stop the governor also stops and the descent of the governor weights operates pivoted switch arm 5I, opening the circuit through wires a and b. At this point the seam has passed the feeler switch and its contacts are open, thus the clutch solenoid or magnet will be de-energized.

The opening of the governor switch also will deenergize the brake solenoid for the drum 6.

The spring brake for the supply reel, which is held to released position by solenoid 45 and its connections when the machine is running, is controlled las follows:

A tilting mercury switch C (Figure e) win be suitably mounted upon the pedal shaft 35 in such manner that slight depression of pedal 371cm will close the contacts thereof prior to any such extent of movement of link 33 as would engage the clutch latching member 38, 39. Also when pedal 3l isfully depressed, throwing the machine into motion, the contacts of mercury switch C will remain closed, to be opened only by the full release vof `pedal 37m: to the position shown in Figure 1. By reason of such construction, slight depression of pedal 3io: will close `a circuit through the positive wires d, e, to electric brake solenoid 45, the return wire being h, .thence through the mercury switch C` to return wires 7c. Thus the supply reel will be released by the releasing action ofthe electric brake solenoid 45, enabling the operator, after cutting out a seam, to pull enough slack to start winding on a new tube.

By reason of the above combination of elements, the seam feeler circuit is closed only for an instant, when releasing the clutch, whereupon the drum brake circuit and the supply reel brake circuit are closed and opened respectively, throwing into operation a brake for the drum and a brake for the'supply reel, and finally, when the machine stops no current flows through any circuit, By reason of the controlled stopping of ,themachine the momentum of rotating elements, the major element of momentum being the drum 5, is so controlled as to relieve the machine and the textile itself of undue strain and to carry the seam to a point where it is stopped most conveniently for the operator as, for example, `midwayof the area between guide roller I5 and the `shafts I9. Any adjustment in timing desired, with respect to the degree of movement `of the seam from the feeler switch may be eifected by movement of a threaded stem G8 carrying yoke Vlili. The stem passes through an aperture in bracket arm 69 and may be held in adjusted position by nut lll. By such adjustment the brakingl action of the drum bracket magnet BM may be slightly increased or decreased to change the length of movement of the seam away from the feeler switch.

It will be seen that the machine may be stopped independently of the seam feeler switch by depression of pedal 37mm. It will also be understood that various. modifications may be made in the form and arrangement of the elements constituting the embodiment illustrated in the drawings without departing from the spirit'of the invention.
