STEEL-WOQL-REMOVING MACHINE.

Original application filed June 5, 1925, Serial NO. 35,155. Divided and this application filed February 18,

@1926. Serial No. 89,244.

My invention relates to steel wool machines and in vparticular to means for con: veying away the strands of steel wool therefrom; and is a division of my application Serial No. 35,155 filed June 5, 1925.

It is the object of my invention to provide means for engaging the delicate steel wool strands and for moving them at a predetermined desired speed away from the steel wool machine as they are manufactured in such a way as to move them positively without injuring the strands.

It is a further object of my invention to provide means of engaging with the strands so asnot to break them but to still frictionallv engage them in such a way that the pull on the strands to remove them away from the machine will be uniform, constant and steady so that the strands will not be broken.

, Referring to the drawings:

Figure 1 is a side elevation of one form of the steel wool removing apparatus of my invention located adjacent to a diagrammatic, illustration of a typical steel wool machine;

Figure 2 is a plan view of one end of the removing means shown in Figure 1;

Figure 3 is a section on the line 33 of Figure l showing the supporting bracket broken away and the supporting shafts in section with a strand of steel wool passing between the steel wool actuating members;

Fi ure 4 is a similar view on the line 4-l of Figure 5 showing a modified form of the steel wool removing means;

Figure 5 is a plan view of a modified form of this removing means consisting of spaced rods; Figure 6 is an end elevation of another form of steel wool removing means using solid rolls which frictionally engage with the steel wool strands passing between them:

Figure 7 is a plan view of this modified form illustrated.

Referring to the drawings in detail, 11 are standards for supporting the steel wool machine table 2 011 either end of which is mounted the supporting brackets consisting of the upright members 3 which terminate in spaced members 4, thus forming Y-shaped brackets at either end of the'machine. It will be understood that this steel wool removing means may be located anywhere,

v the machine.

that is, above, below or atone side of the steel wool machine but for the purpose 0t illustration and the ease thereof, 1 have shown it in a typical satisfactory form above Journaled in the ends of these arms 4: of the Y-shaped bracket are the 'shafts 5 and (i which are thus supported in parallelrelationship. On one of these shafts is mounted a pulley 7 actuated by a belt 8 from any suitable source of power: These shafts have mounted thereon, opposite to one another, thegears 9 and 10 which mesh with one another and serve to turn the shafts 5 and (S in unison with one another -so that there will be synchronous movement of the shai'ts and any means which they may carry. The shafts carry, on suitable end supporting members or plates 11 corrugated drums 12, such corrugations being formed as round topped ridges 13 which are relatively widely spaced with deep valleys ll thcrebetwecn. These two corrugated drums have their projecting corrugations or ridges lZ} adapted to project within the corresponding valleys ll on the other corrugated drum but the drums are so positioned through the gearing 9 and it) that while successive ridges project into opposite successive valleys, yet the drums do not touch each other but are spaced a sutlicient distance between their adjacent surfaces to accommodate the steel wool strands 15 passing from the steel wool cutting tools 16. These strands are fed between the corrugated rolls and are bent in serpentine form as they pass between the corrugations of the rolls where the corrugations of the rolls are adjacent, thus providing a frictional engagement for moving the strands. The strands are therefore moved by this engagement at a predetermined speed without jerking or pulling and without rupture of the strands but they are nevertheless positively moved. The strands are easily examined as they are thus moved from the machine enabling the operator to make the adjustments on the cutting tools as mav be desired.

These strands are cut from the wire 17 passed over the drums 18 in the usual manner. These drums are mounted on the table 2 on the vertical spindles 19. It will be understood, however. that the details of the steel wool machine are immaterial as one 01' more wires may be used and other de tails of the machine may be modified. The drums shown in Figures 1 2 and 3 are preferably formed of corrugated sheet metal. in Figure -'l an open type 0t removing mechanism is illustratcd where it is desired to hare this form which provides for a circulation of air. The mechanism is the same with the exception that instead oil having actuating drums with continuous t'accs, rods it] are provided mounted on the crests of the teeth '31 ot the end mcinhers 2:2. The wall engages with thee rods which loosely interlock as in the case of the forms shown in Figures l :2 and 3, not touching each other and being sutlicicntlr spaced to accoinuiodate the steel wool strand which is trio tionally engaged by the rods and moved away from the tools.

.lte't'crrin to the term shown in Figures ti and i'. it: will be obscrred that the mechanism is the same save that two solid, mooth taccdrolls 132-} arc employed which are sutliciently spaced to a minute degree not: to engage one another but to insure t'rictional engagement with the line strands nit wool which pass 'therebctwcm,

it will be understood that I desire to comprchend within my invention srtch modifications as may be nccessar i to adapt it to rarying conditions.

Haring; thus fully described my invention. what It claim as new and desire to secure by Letters Patent, is:-

1. In a steel wool machine a plurality of cutters. lending means for feeding a wire to said cutters. mcuns to remove steel wool strands from the cutters individually con sisting of a pair of synchronously moving, closely adjacent steel wool engaging n1cinman hers spaced apart from each other whereby a circulation ot air is permitted and adapted to :trictionally engage the wool strands to pull them away "from the machine, said members being adapted to move together sync-hronously but not to engage one another and only adapted to frictionally engage With the steel wool strands passing thercbetween without tension, and said members being .ltlt'tllOtlllOIL so arranged that their alter nate projections and depressions on said members, the projections of one member adapted to project; into the depre=sion oi the other member without engaging with the member and the strands being adapted to pass between the alternate projections and depressions in the members \YllGlG-tllQjtl are adjacent to one another, thus frictional bends being formed in the steel WOOl strands to assist in pulling the st ands away from the machine.

2. In a steel wool machine a plurality of cutters, teeding mean for feeding a Wire to said cutters, means for removing steel Wool strands from said cutters individually con sisting" of a pair of parallel spaced shatits, means for causing said shafts to rotate together, means on said shafts to carry a plurality of spaced rods whereby a circulation oft air is permitted and adapted to project; one ot the rods on one shat't between two rods on the other shalt as they come opposite to one another without said rods touching, the space being su'tiicient to pass a steel wool strand therebetwccn for frictional engagement with the rods.

In testimony"whereof, I afiix my signatitre.
