CARDING-ENGINE.

Specification of Letters Eatent.

Eat-tented Feb. 1?, i @314,

b aZZ whom it may concern Be it known that I, PATRICK L. MoBnios, a citizen of the United States, residing at Gorhani, in the county of Cumberland and ttate of Maine, have invented a certain new and useful Improvement in Caroling-Engines, of which the following is a specification.

This invention relates to carding engines and consists in the combinations and devices hereinafterdescribed and claimed.

Cording engines have hitherto usually in cluded a main cylinder or swift arranged between the feed-rolls and doiier-comb or other means for removing the fibrous materials from the card. Around the circumference of such main cylinder or swift are placed a plurality of smaller cylinders, workers or carding rolls, the teeth of the card-clothing on said workers being arranged pointto point with the teeth of the main cylinder, for the purpose of removing a portion of the uneven web of stock passing around said main cylinder, which stock is returned to the main cylinder to be again recorded by the same or another worker. Such a main cylinder or swift is driven from fifty to one hundred and twenty-five times faster in surface sp'eed then the wor ers or carding-rolls and it is necessary to run the main cylinder at a very-high speed, say from fifteen thousand to twenty five thousand inches per minute, according to the nature or" the stock to be carded, the finer thestock the greater the speed, be

cause all the carding is done by said main cylinder and said workers, the speed of the workers being from seventy five to two hundred surface inches net minute. This great diii'erence in the speed of the main cylinder and workers causes a breaking of the fibers, insufficient carding and loss of production, creates bunches, flyings and waste, increases the cost of the yarn and makes what is known as tender yarn or yarn of less strength. r

The object of my invention is to provide for carding all kinds of fibrous materials by a plurality of pairs of slowly operating cardclothed rolls arranged in lines between the usual feeding" devices and dofier and its, comb or other means for removing the carded stock from the carding engine. These rolls are preferably arranged in three horizontal tiers, the to and bottom rolls or rolls of the top and ottom tiers being each arranged in an angle between two adjacent rolls (hereinafter for distinction celled cylinders) of the middle tier end in carding relation with one and in stripping relation with the other otsoid adjacentcylinders, said top and bottorn'rolls not return mg the stock removed by themto the some cylinder from which it reinoved nntil said stock has recarded by a roll of the other tier. l

By arranging two cylinders with their teeth point to back with each other and operating them at a surface speed of about two thousand to three thousand surface nches per minute and arranging a roll above, in the angle between the two and another roll in the lower angle between the two, each a 1 roll being in working relation with both cylinders and eech roll. stripping one cylinder and carding with the other cylinder, the relation of said rolls to the same cylinder being reversed, I have found that i could work any fibrous web so as to make an even blend of itproviding I nsedtwo sets of these cylinders and rolls, which sets of cylinders are'not in speed relation to each other, that is, the speed of one set is not determined by the speed of the other. This is accomplished by arranging between said two sets e conveyer cylinder which revolves in the same direction with first cylinder of the second set and in the opposite direction to the second cylinder of the first set. This conveyor cylinder permits any desired speed to be maintained for either the first or second set independently ot the speed of the other set so that the stock thesis not properly carded on the first 2' ieedingdn set on reaching the second or feeding-out set me again be returned to the second or first cy inder of the first set to pass through the same processnpreviously described.

1 do not limit myself to the use of two sets of cylinders anda conveyor cylinder, be-

cause three or more sets may be used with. a conveyor cylinder between each set and the following set, but It have found that twosuch sets used with therolls and the other cylinders herein shown and described are snfici'ent for practical purposes and occlipy no greater door-space than the ordinary carding engine in which a main cylinder and workers are employed. In the accompenyi IS a diagrammatic representation ns de elevation of the rolls and cylinders of a cardng drawing the figure der in carding relation with the second of veyer cylinder.

laden with the last cylinder of the first set I claim as my invention 1. In a carding engine, the combination of two feeding-in cylinders, a conveyer cylinder in carding relation with the second of the feeding-in cylinders and two feedingout cylinders in stripping relation with each other, the first of said feeding-out cylinders being'in stripping relation with said con- In a carding engine, the combination of two feeding-in cylinders, a roll arranged in an angle between said feeding-in cylinders and in carding relation with the second of said cylinders and in stripping relation with the first of said cylinders, a'conveyer cylinder in carding relation with the second feeding-in cylinder and two feeding-out cylinders, the first of which is in stripping relation with said conveyer cylinder and with the second of said feeding-out cylinders, and a roll arranged in the angle between said feeding-out cylinders and in carding relation with the second of said feeding-out cylinders and in stripping relatdion with the first of said feeding-out cyliners.

3. In a carding engine, the combination of a set of feeding-in cylinders, a set of feeding-outicylinders, a conveyor cylinder arranged between said sets and in carding relation with the last cylinder of the first set and in stripping relation with the first cylinder of the second set, the speed of each set being independent of the speed of the other set.

4. In a carding engine, the combination of two feeding-1n cylinders, a conveyei cyhnthe feeding-in cylinde s, two "feeding-out cylinders in stripping relation with each other, the first of said feeding-out cylinders being in stripping relation with said conveyer cylinder, and rolls arranged in the angles between said feeding-in cylinders above and below, each roll being in carding relation with one of said cylinders and stripping relation to the other of said cylink ders and the relation of said rolls to the same cylinder being reversed.

5. In a carding engine, the combination of a set of feeding-in cylinders, a set of feeding-out cylinders, a conveyer cylinder lirranged between said sets'and in carding flieand in stripping relation with the first cylinder of the second set and rolls arranged above and below in the angles between the cylinders of each set, each roll being in card- )in relation D .conveyer-cylinder arranged ing relation with one of the cylinders and in stripping relation with the other cylinder of the corresponding set and the relation of I said rolls to the same cylinder being reversed.

6. In a cardin engine, the combination of a set of feeding-in cylinders, a set of feeding-out cylinders, a conveyer cylinder arranged between said sets and in carding relation with the last cylinder of the first set and in stripping relation with. the first cylinder of the second set, rolls arranged above and below in the angles between the cylinders of each set, each roll being in carding relation with one of the cylinders and in stripping relation with the other cylinder of the corresponding set and the relation of said rolls to the' same cylinder being reversed and transfer rolls.

7. In a carding engine, the combination with feeding and dofiing devices of a set of feeding-in cylinders, a set of feeding-out cylinders, a conveyer cylinder arranged between said sets and in carding relation with the last cylinder of the first set and in stripping relation with the first cylinder of the second set, rolls arranged above and below in the angles between the cylinders of each set, each roll being in carding relation with one of: the cylinders and in stripping relation with the other cylinder of the corresponding set and the relation of said rolls to the same cylinder being reversed and transfer rolls.

8. In a carding engine, the combination with feeding and dotting devices, of a feeding-cylinder, a feeding-out cylinder, a conyeyer-cylinder arranged between said first named cylinders, and in carding relation with said feeding-in cylinder and in strip ping relation with said feeding-out cylinder, and rolls arranged in the angles between said cylinders, each roll being in stripwith said conveyer-cylinder.
