Application filed Ma 21, 1913. Serial No. 768,951.

To all whom it may concern Be it known that I, WILLIAM LONZO, a citizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Bobbin-Cleaner, of which the following is a specification.

This invention relates to a machine for stripping filling or roving from bobbins.

The principal objects of the invention are toprovide a machine of this character capable of being constructed with a plurality of units, each requiring such simple motions on the part of the operator that a single operator can take care of four or more of these units, thus reducing the labor cost very materially, and to provide a machine having a sort of hopper for receiving the bobbins so arranged that the bobbins can be thrown into it without the necessity of the operator putting his hand into the hopper or into the space which is passed over by the moving parts of the machine, thus eliminating all danger, and all fear, of injury to the hand of the operator; also to provide a construction in which the bobbins can be stripped efficiently, although held in a horizontal position, and in which the filling stripped from the bobbin is discharged down through the bottom of the hopper and the bobbin also is preferably automatically discharged at sub stantially the same point.

A further object of the invention is to provide for taking up the filling discharged with the bobbins after it has been removed fro-m them and winding the same on a rotary member so that the filling can be collected in one place and disposed of in a simple and convenient manner.

The invention also involves improvements in details of construction and combinations of parts as will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a plan of a portion of a machine constructed in accordance with this in vention; Fig. 2 is a front elevation thereof; Fig. 3 is a plan on enlarged scale of one of the bobbin hoppers and connected parts and showing the roving partially stripped from a bobbin; Fig. 4 is a sectional view on the line 4:& of Fig. 1; Fig. 5 is a front eleva tion of the jaws through which the bobbin is forced; Fig. 6 is a sectional view on the line 66 of Fig. 1; and Fig. 7 is a sectional view on the line 7-7 of Fig. l.

The machine is shown in the drawings in a form in which it comprises a main frame 10. This frame supports a shaft 11 which is provided with ordinary loose and tight pulleys 12 for receiving the power from a belt. A belt shifter 13 is indicated.

On the shaft 11 is a pinion or gear 14 meshing with a gear 15 on a shaft 16 which consequently is driven constantly while the belt is on the tight pulley. This shaft 16 is provided with a plurality of segmental gears 17 fixed thereon, one for each unit of the machine. Each of these gears is designed to mesh with a rack 18 on a slide 19. These slides rest onrolls 20 mounted in bearings on brackets 21 on the frame 10.

To each of the slides 19 at the bottom is connected the end of a flexible belt 23 adapted to wind on a drum 24, these drums being fixed to a shaft 25 parallel with the shaft 16. This shaft 25 is provided with coiled springs 26 for normally keeping the shaft in the position shown in Fig. 7. On the end of each slide is a plunger 27 passing through, and supported by, a bracket 28. Slidably mounted on brackets 29 are rods 30 each having a plate 31 on the end provided with a soft face for receiving the impact of the slide 19. Each of these rods is provided with a buffer spring 82 and a collar 33. The bracket 28 carriesone end of a hopper 37 for receiving the bobbins. This hopper is provided with guides 38 which assist in properly locating the small end of the bobbin in line with the plunger 27 and the plunger moves forward also serve as guides for the end of the plunger.

It will be obvious that as the shaft 16 rotates continuouslv in one direction, indicated by the arrow in Fig. 7. the teeth 011 the gear 17 engage with the teeth on the rack 18 once during each rotation and force the plungers forward positively. Then the gear teeth move out of mesh with the rack teeth and the springs 26 bring the slides back very rapidly against the buffers. By adjustment of the collar 33 along the rod 30, the teeth of the rack 18 may be stopped in proper position to be smoothly engaged by the teeth of the revolving gear 17.

On shaft 16 there is a cam 40, (Fig. 6) this cam being designed to engage and operate a lever 41, passing through a slot in a stationary bracket 42 and having projections 1-3 for loosely holding it at that end. In other words, the lever is fulcrumed on the bracket. On the other end this lever is provided with a flexible connection or belt 44 which passes under an idler 45 supported to turn on brackets 46 carried by the frame. This belt passes around a drum 47 (Fig. 3) which is mounted on a shaft 48 provided with a torsion spring 49. The several drums are connected to a reciprocating rod 50 by means of a plurality of these flexible connec tions 4-4:. Each spring 49 is held at one end by a claw 51 on a collar secured to the rod 48, the other end of said spring being fixedly engaged by the hopper 37.

On the shaft 48 is fixed a jaw 57, this jaw swinging with the shaft from the full line position in Fig. 5 to the dotted line position. Under this jaw is a stationary jaw 58 with which the movable jaw cotjperates.

The stationary jaw 58 is provided with a recessed edge 59 substantially fitting the shank of the bobbin and over which the bobbin is forced by the plunger 27 when the jaw 57 is down in position, the jaws 57 and 58 cotiperating to remove the waste.

The placing of the bobbin in position in the hopper causes the large end thereof to engage a lever 60 (Fig. 4:) which is normally held in an inclined position by a spring 61. This lever has a stop 62 adapted to engage a lug 63 on a bracket 64 which supports one end of the hopper for limiting its upper position to that shown in Fig. 4. The lever is provided with a guard 65 on the end.

Below the opening 39 in each hopper is pivoted a sheet metal plate 70, (Figs. 1 and 41) the lower end of the same being held up by a spring 71. This receives both the waste and the bobbins.

The shaft 11 is provided with a pulley 7 3 which by a belt drives a pulley 74: on a parallel shaft 75. On this shaft are a series of wheels 76, one for each unit of the machine. These wheels have notches 77 in their peripheries. This shaft rotates constantly when the machine is operated.

The operation of the machine is as follows: The shaft 11 being set into operation the operator throws the bobbins into the hopper 37 one at a time with their large ends extending over the jaw 58 and their small ends between the guards 38. Upon each operation of the shaft 16 each of the plungers27 moves forward at a measured rate of speed, and when each one starts forward the movable aw 57 connected with the same unit of the machine is allowed to move downwardly under the influence of its spring 49 into the position shown in full lines in Fig. 5. As the plunger moves for ward, it forces the bobbin out through the space between the two jaws and against the lever 60, pressing said lever backward to a nearly horizontal position. As soon as the teeth 17 pass beyond the rack 18 the spring 26 forces the rack back and withdraws the plunger. At the same time the jaw 57 commences to move up. Now there is nothing to support the small end of the bobbin, but the large end is supported'by the guard 65 or other part of the lever 60 which is pressed by the spring in a forward upward direction. At first this presses the shank of the bobbin up against the jaw 57 and forces the small end of the bobbin down through the opening 89. Thereafter as the jaw 57 moves out of the way, the spring 61 swings thelever 60 up so as to slide the bobbin down through the opening through which the filling has already passed. 7

It will be observed that .a feature of importance lies in having the movable one of the jaws, namely, 57, swing upwardly to an upright position, where it will be entirely out of the way and will, therefore, not interfere with the proper and ready positioning of the bobbin in the hopper. This construction enables me to arrange the hoppers in horizontal position with their open sides facing upwardly, in which position they are most convenient for receiving the bobbins, as isevident.

The constant rotation of the shaft 75 causes the wheels 76. to engage the filling as its slides down the plate 7 O and the edges.

of the notches 77 engage the filling threads and wind them up on these wheels. As the bobbins engage the wheels 76, the pressure communicated thereto, together with the weight of the bobbins, depresses the plate 70 and allows the bobbins to pass under the wheels after which they are'discharged from the end of the receiver into a basket or other receptacle below. These wheels 76 have to be cleaned occasionally, which is done by running a knife along the notches to cut the threads from the wheel and permit them to be released and taken away. In this way it will be seen that a single operator cantakew care of a comparatively large number of units as all he has to do in the ordinary operation of the device is to deposit a plurality of bobbins in as many receptacles. If all the plungers work simultaneously, as indicated in the drawings, all the bobbins should be deposited before the plungers start forward, but it is within the scope of the invention especially when a large number of units are employed to have the plungers work one after another so that the operator can deposit his bobbins in sequence. The only other attention that has to be paid to the machine is to clean the wheels 76 occasionally, and, of course, the necessary repairs.

Although I have shown and described only a single embodiment of the invention, I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in these respects, but
