Application led. April 21, 1923. Serial No. 633,763.

@acera in the county of Hamp- Massachusetts, a subject of George V, King of England, have 1nvented Polishing Machines, ing/g is a specification.

a new and useful improvement 1n of which the follow- My invention relates to a machine whereby yarn or cloth may be softened and at the same time polished so that the product becomes of a soft silky texture.

According to my invention the material is passed pro gressively between a series of polishers which may be ing faster rubbers or brushes and which movthan the feed of the material and preferably arranged to stretch the material by pushing it out of its normal line of travel,

rub its surface in such a manner that it acuuires a sheen which gives it the desired silk-like. appearance. My invention will be understood by reference to the drawings in which it is shown in longitudinal section and somewhat diagrannnatically. It will be understood that the rotating` parts are supported at each endl by similar' sup-ports.

l is a frame upon snpporte d. end by suitable guide rolls il, 4:.

bearings which the machine is 2, 2 are shafts supported at each 3 and carrying 5 and 6 are supports located near each end of the. frame 1, one on each end of the machine which may be as wide as is convenient.

They carry shafts 51 and 61, respectively,

running across the machine and on them are mounted rolls Power is so ap alied to these wili` he rotated with frames 5 and 6 52 and 62, respectively.

shafts that they equal speed. On the are also mounted adjustable hearings 53 and 63 which carry shafts 511 and (Se each of which carries a roll and G5 which rests upon the rolls 52 and 62 or upon the material a, resting` upon these rolls.

are alike. Each sup- 91, each of which car- 72 and 92. These spiders are the detailed description of will describe the other equally well.

one The hub 7 3 attached to the shaft 71 to turn therewith. From this hub project arms 74, each having an arrowhead 75 at its outer end. These shafts 71 and 91 extend across the machine and are supported at both ends, and at each end of each shaft is a spider 72 and 92. There may be such a number of intermediate spiders on each shaft as will .be necessary to make the mechanism stiif.

Each arrowhead 75 has a facing 76 referably of wood or other good polis ing material, this facing extending across the nachine and being supported by the spiders so that they form a. series of strong firm polishing surfaces which successively engage the surface of the materia-l and stretch and polish it.

The frame 8 carries a shaft 81 on which is mounted spiders 82, in all respects like the spider 72 which has been described in detail, and the frames 7, 8 and 9 are mounted sui'liciently near and the shafts are so mounted in them that the arms of the spiders interlock, so to speak, and thus straining the material as it passes between them stretches it so that it breaks down its harshness, making it soft and giving it a silky finish and gloss. The shafts 71, 81 and 91, preferably provided with intermeshing gea-rs by means of which they are rotated in the direction of the arrows, are rotated at the same speed.

T he frame 8 is higher than the frames 7 and 9 and is forked` at its upper end carrying,I at its top two guide rolls 87 and 89 so that the material a passing in between the rolls 52 and 55 passes over roll 87, down between the facings of spiders 72 and 82, under rolls a, up between spiders 82 and 92, and out over roll 89 and between the withdrawing rolls 62 and 65. As these rolls and the rolls 52 and 55 run at equal speeds, the material is always under tension and held against the action ofthe spider facings.

ln practice the speed at which the material is carried through the machine is governed by the speed of the rolls 52 and 62 which cooperate with the rolls 53 and 63 to grip the material and feed it positively to and through the machine. The speed of the spiders is somewhat faster than the feed of the material, which is somewhat slow, so that the entire surface of the material is polished as it travels between the spiders. The speed of the spiders may be regulated in any convenient way according to the material to be treated and the desired result.

I do not mean to limit my invention to the construction shown or the material of which the polishers are made, but will state that the embodiment of it described has produced exceedingly good results.

lVhat I claim as my invention is l. A polishing machine comprising a feed mechanism, a withdrawing mechanism and a polishing mechanism located between said feed and withdrawing mechanisms to contact with the material being fed, and means for moving said polishing mechanism with relation to said material whereby it will polish said material, said polishing mechanism comprising rotary members each having arms carrying polishing surfaces, said rotary members being located whereby said arms will interlock and engage the material to be polished on both sides thereof and divert the material to be polished out of a straight line whereby it will be held under tension during said polishing process.

2. A polishing machine comprising a feed mechanism and a withdrawing mechanism and a polishing mechanism located between said feed and withdrawing` mechanisms and adapted to engage both sides of said material and means for operating said polishing mechanism in a direction opposite to said feed whereby it will move in Contact with the surfaces of the material to be polished at a more rapid rate than the feed of said material, said polishing mechanism comprising a plurality of rotating .elements having arms, the arms on one rotary element interlocking with thearms on an adjacent rotary element and each arm carrying a polishing` surface whereby the material to be polished will be diverted from a straight path and simultaneously will be polished on both sides thereof.

3. A polishing machine comprising a yfeed mechanism and a withdrawing mechanism and a polishing mechanism located between said feed and withdrawing mechanisms and means for operating said polishing mechanism whereby it will move in contact with the surface of the material to be polished at a more rapid rate than the feed of said material, said polishing mechanism comprising a series of rotary members each having arms, said rotary members being located in close relation whereby their arms will interlock and the material to be polished will be diverted from a straightl path.

4C. A polishing mechanism comprising a series of spiders having arms and polishing surfaces located at the ends of'said arms, said spiders being located to engage both sides of the material to be polished and in close rrelation whereby the arms of one spider will overlap the arms of the next spider, and mechanism for feeding the material to he polished under tension between said spiders.

5. ln a polishing machine, a polishing element comprising three rotary polishing members, the axis of said polishing members being loca-ted out of line and each comprising a series of arms, the axis of said polishing members being located in proximity whereby, when rotated, the arms of one polishing member will interlock with those of the one next to it, and means for feeding the material to be polished between said polishing members at a speed whereby the polishing surfaces of said members will move with relation to said material and said material will be polished on both sides by the contact of said polishing members therewith.
