STEEL-WOOL MACHINE.

' Application filed June 5, 1925. Serial No. 35,155.

My invention relates to steel wool machines and in particular to means forconveying away the strands of steel wool there- 5 a 1 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 thesteel wool machine as they are manufactured in 10 such away as to move them positively without injuring the strands. a

' a It is a furthr' object of my invention to provide means of enga'ging w'ith the, strands so as not to break them but to still frictional- 15 ly engage them in .such a waythat the pull onthestrands'to remove thenrfrom the machine will be uniform, constant and steady so that the strands will not be broken.

Referring to the drawings: r v -F'gu'r'e '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; Figure2 is a planview of one end of the 25 removing means shown in Figure 1; a Figure 3 is a'section on the line 33 of- Figure 1 showingthe supporting bracket broken, away and the supporting shafts in section with a strand of steel. wool passing between the steel wool actuating members;

. Fi ured is. a similar view on the line 4-4 of"Figure 5showi'ng a modified form of the steel wool removing means;

.ofathis removing'means consisting of spaced re s; a a

Figure 6 isan end elevation of another form of steel "wool removing means using solid rolls which frictionally engage with the steel Wool-strands passing between them; v

Figure 7 is a'plan view of. this modified form illustrated; 1' Referring to the drawings in detail, 1 -1 are standards for, supporting the steel .wool 'maehinetable, 2 on 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 endof themachine. It will be understood that this steel wool removing means'may be located anywhere, that -is,above, below" or at one side of the'steel wool ma'chine but for the purpose of illustration and th'e ease thereof, 1 have shown it in a typical satisfactory form above the Figure-5 is aplan view of a modified form lmachinei Journaledin the ends'of these arms 1 of the Y-shaped bracket are the shafts .5 and 6 which are thus supported in parallel relationship. On one of these shafts is mounted a pulley 7 actuated by a belt 8 from 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 14 therebetween.

These two corrugated drums have their projecting corrugations or ridges 13 adapted to project within the corresponding valleys 14 on the other corrugated drum but the drums are so positioned through the gearing 9 and 10 that while successive ridges project into opposite successive valleys, yet the drums do not touch each other but are spaced 1 .TllllClGllll distance between their adjacent surfaces to accomo date 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 movlng 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 enablingthe operator to make the adjustments on the cutting tools as may be desired.

These strands are out from the wire 17 passed lover thedrums 18 in the usual manner. These drums are mounted on the table 2 on the verticalspindles 19. It will be unin the case of the forms shown in Fi uresl,

2 and 3, not touching each other andbeing sufiiciently spaced to accomodate the steel wool strand which is frictionally engagecljgy the rods and moved away from the tools.

Referring to the form shown in Figures 6 and 7, it will be observed that the mech anism is the same save that two solid, smooth-faced rolls 23 are employed WhlCll are suiiiciently spaced to a mmute degree not 7 to engage one another but to insure frictional engagement with the fine strands of wool which pass therebetween.

It will be understood that I desire to comprehend within my invention such modifications as ma be necessary to adapt it to varying con itions' Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is

nov

1. In a steel wool machine, cutters for said steel wool machine, means for feeding a wire to said cutters whereby a plurality of individual strands of steel wool are cut simultaneously by said cutters from said b wire, means to remove steel wool strands from the cutters consisting of a pair of synohronously. moving, .closely ad acent steel wool engaging members adapted to frictionally engage the wool strands individually to pull them away from the cutters, said friction engagin members having means for grasping said steel wool strands where by only-the, dead weight of the wool strands is lifted by said friction engaging members without tension.

2. In 'a steel wool machine, cutters for said steel wool machine, means for feedinga' wire to said cutters whereby plurality of individual strands of steel wool are out simultaneously by said cutters from said wire, means to remove steel wool strands from the cutters consisfin of a pair of synchronously IDOVIIIO, c ose y adjacent steel wool engaging mem ers adapted to frictionall engage the wool strands to pull them away cm the machine, said members being adapted to move together synchronously but not to en age one another and only adapted to very lightly frictionally engage with the individuaL steel wool strands passing therebetween whereby only the dead weight of the wool strands is supported by said members without tension.-

3. In a steel wool machine, cutters for said steel wool machine and means for feed ing wire to said cutters whereby a plurality of strands of wire are cut simultaneously, means to remove steel wool strands from the cutters consisting of a pair of synchronously moving, closely adjacent steel wool engaging membersadapted to frictionally engage the wool strands to pull them away from the machine, said members being adapted to move together synchronously but not to engage one another and only adapted to frictionally engage with the steel wool strands passing therebetween, and said members beingfurthermore so arranged with alternate plOjeCtlqlls and depresslons on said members, the projections of one member adapted to project into the depression of the other member without engaging with the memb er and thestrands'being adapted to pass between the alternate proy'ections and depressions in the members w iere they are adac'ent to one another, thus frictional bends being formed in the steel wool strands to assist in pulling the strands away from the machine.

In a steel wool machine, cutters for i said steel wool machine, means for feeding a wire to said cutters whereby a plurality of strands of wire are cut simultaneously by said cutters, means for removing the strands from said cutters, consisting of a pair of synchronously rotating corrugated drums adapted to have the corrugations successively interlocked but never engaged and eing sufiicient-ly spaced to. permit'of the passage of steel wool strands therebetween for very light frictional engagement with I said drums suflicient tomove a strand of steel wool to carry its dead weight but not to put it under tension whereby only the dead weight of the wool strands is supported and lifted by said steel wool engaging members. a a.

5. In a steel wool machine, cutters for said steel wool machine, means for feeding a wire to said cutters whereby a plurality of individual strands of steel wool are cut simultaneously by said cutters from said wire, means for moving steel wool strands away from the cutters consisting of parallel shafts, gearingmounted on said shafts to insure their rotation synchronously,

means for actuating said shafts, and corrugated drums mounted on said shafts adapted to interlock without touching being sufficiently spaced for steel wool strands to pass therebetween infrictional engagement with said drums, said'frictiona'l engagement being only sufficient to move the strands of wool away from the machine without'pulling the strands and putting them under tension. 1
