Winterthur,-='Switzerland Application February 10, 1947;;Serial-No: 727,626 1 """In Switzerland Octoher 19;-"1946u "-1 a that. 101.19 1164) Duringthe operation of aj'textile fiber comber,
wastexor noil is deposited inthacombs or needles mounted on the comb cylinders,'- forming at times a felted fleece therein or in portions thereof, which cannot be removed by the circular brush in the course of combing. Such waste materially impairs the operation of the combs," resulting in faulty tops. For this reason, the needle segments of the comb cylinders have to be thoroughly cleaned after a certain period of operation. For the sake of distinguishing between primary comb cleaning, obtained in regular operation, and secondary cleaning applied from time to time as required, such secondary cleaning hereinafter shall be referred to as clearing.
To such end, the comb cylinders of prior combers are made to co-operate with the rotary brushes, while running idle for a certain length of time. During such clearing operations, the
feed of comber lap of necessity has to be stopped, and, for the purpose of resuming the combing operation, all the laps advanced first have to be redrawn into the feed rollers, and the tops into the draw-frame and into the sliver delivery mechanism. Such resetting causes reduced output and requires additional work on the part of the attendants, for which reason the clearing of the needle segments on the comb cylinders often will be neglected. The intensity of clearing atments, the clearing arrangement according to my present invention comprises a change-speed gear for varying the ratio of the rotary speeds between, comb shaft and brush shaft during the clearing of the combs, relative to the conditions prevailing during operation. The speed of rotation of the cylinders is preferably reduced during such clearing action.
The accompanying drawing shows one embodiment of the invention by way of example. A plurality of cylindersonly one being shown in the drawing, denoted by numeral l-are fixedly mounted on a comb shaft 2. A rotary brush 4, co-operating with cylinder I and fixedly mounted on shaft 3, is operatively connected with a spur gear I by means of spur gears 5 and 6. Gear 1 is keyed to shaft 8 of the comber which here is not further illustrated. Two further spur gears 9 and it are mounted loosely or rotatably on shaft 8 and mesh with spur gears H and I2, respectively, which latter are 2 keyed-etc com-brshartez iGcaNyit and I2 a se substantiallysmallend ameten than ge rs .15 an H.:.-A belt-:drivespul-leyr r3 is. k yed to main shaft 8. .QA; clutchmember 71351. 5 mounted axiallydisplaceably; along:keywayz.l;4,ion shaft Bbetween; 1 gears 9 andz;l;fl.1.r;: Thezhub 1:5 anddliof sears .8. and I6 form the counter-parts to the clutch member I5. A lever l8 in the form of a fork engages the latter and is keyed to a rock-axle 18 which is operated by a hand lever 20 mounted outside the machine case, the latter not being shown. -By swinging hand lever 26 into one or the other terminal position I or II, clutch l5 alternatively may be brought to mesh with hub It or II of gear 9 or I!) respectively, for the purpose of transmitting the rotary motion of main shaft 8 onto gear 9 or ID respectively.
Brush t has a uniform rotary speed, since it is driven through ear train 1, Band 5 by the main shaft 8. When, during operation of the comber, clutch l5 engages hub [1 of gear II], the comb cylinder 1 is driven by gears II] and I2, and cylinder I, which is provided with the combs 2|, rotates faster than brush 4. For cleaning needles 2|, lever 20 is swung from position I into position II. Wheels 9 and H, now, rotate cylinder l at a considerably reduced speed. The difference between the rotary speeds of brush 2 and cylinder I thus is substantially increased relative to that attained during the combing operation proper. Brush 4 thus clears cylinder I thoroughly.
Since the improved cleaning and clearing operation depends only on changing the peripheral speed between the needle segment 2| and the comb brush 1 and since the entire feeding, combing and delivery mechanism continues operating, the production of the combing machine and hence the flow of fibrous material in the machine is not interrupted during the stripping of the needle segments 2|. Consequently the tedious reinsertion of the batting and strips usually required after cleaning the comb teeth is eliminated.
Since, further, the comber operates at very low speed, on account of the gear ratios provided for, all the operations on the comber may be surveyed at ease. This greatly facilitates the adjustment of the latter, which is ofparticular importance in case of variations in the quality of the lap to be combed.
What I claim and desire to secure by Letters Patent is: g
1. In a textile combing and comb-cleaning and clearing mechanism, a drive shaft, a comb-cylim moved in normal speed operation, said variable E:
speed drive means including a shifting mechanism and means for operating said shifting mechanism.
2. In a mechanism according to claim 1, said variable speed drive means comprising two pairs 1 of speed-changing gears of different gear ratios, one gear of each pair being rotatably and axially unmovably mounted on said drive shaft, the other gears of said pairs being fixedly mounted on the comb-cylinder shaft, the gears mounted on the drive shaft having clutch faces axially facing each other, and said shifting mechanism comprising a two-faced clutch member nonrotatably and axially movably mounted on said drive shaft between the gears mounted thereon for engagement with either of said gear clutch faces.
3. In a mechanism according to claim 2, said shifting mechanism comprising a lever in the shape of a fork and movable in a plane containing the rotation axis of said drive shaft and movably engaging said clutch member, and a handle connected with said lever for moving said clutch member to engage either one or the other of said gear clutch faces.
KARL STRASSLER.
