ROBERT F. BARKER, OF BOSTON, MASSACHUSETTS.

CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 287,405, dated October-30, 1883.

Application filed j'anuary 2, 1883. (No model.)

To all whom it n tay concern:

Be it known that I, ROBERT FosTEE BAR- KER, a subject of the Queen of Great Britain, but a resident of Boston, of the county of Suffolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Carding-Machines; and I do. hereby declare the same to be described in the following specification and representedin the accompanying drawings, of which Figure 1 denotes a longitudinal section of a carding engine provided with my invention, the nature of which is duly set forth' in the claim hereinafter presented. Fig. 2 is a section,on a larger scale than they are represented in Fig. 1, of the lower rotary beater and the parts immediately adjacent thereto.

In the drawings the directions of revolution of the various rotary parts of the machine are indicated by arrows placed on them.

In carrying out my invention I employ with the main card-cylinder and the doffer, and

the anti-suction plate of the former placed be tween them, a rotary beater arranged directly over the said plate and between the doffer and main card-cylinder. This auxiliary rotary beater is to remove from the doffer any extraneous matters that may have passed by the knife or blade over it and settled upon the doffer. In knockingtheseextraneous matters from the doffer the blades of the rotary beater discharge them between the anti-suction plate and the main card-cylinder, from whence they are driven down into the space below such main card cylinder that is, into the fly or dust-box.

In the drawings, A denotes the main cylinder; B, the licker-in; C and D, the feedrolls; E, the lap-roll; F F, &c., the combingrolls; G, the cleaning-rolls; H, the raising-cylinder; I, the cleaningroll of the raising-cylinder; K, the knife or stationary blade, and L the doffer.

The rotary brush of the raising-cylinder is shown at a, its rotary beater at I), and the receiving-trough of the latter at 0, they being arranged, as shown, between the series of combing and cleaning rolls and the raisingcylinder; and such brush and beater being constructed of the usual material and in the usual way in which analogous parts of carding-machines are made.

All the parts specifically stated above are constructed, arranged, and operated substantially as in various carding-engines already fer has been located near such plate.

known'-such,for instance, as the one shown in Patent No. 261,016.

. The anti-suction plate is arranged under the main card-cylinder and between it and the doffer, in the manner as represented at d. It is to prevent atmospheric suction induced by the movement of the main card-cylinder from disturbing the fibers on the doffer, such plate being stationary and secured to the frame of the machine. This plate d is of less length than a quarter of the circumference of the main cylinder A, so that such plate is wholly within a quadrant formed by the horizontal and vertical axes of this cylinder. Directly over the said anti-suction plate is the auxiliary beater e, which is a shaft provided with 'blades or wings set radially to it. This beater extends across the doffer, and is to be rapidly revolved in the direction of the arrow over it by suitable mechanism, its purpose having been hereinbefore described. 7

Prior to this invention a carding-machine has been devised which is provided with an ant-tsuction plate arranged below and near to the main cylinder, and a beater for the dof- In my device, the beater, being placed above the plate and rotated in the same direction with the doffer, carries all impurities inside of the anti-suction plate, where they are caught by the current, of air and carried off also a carding-machine has been provided with a concaveplate which extends below the main cylinder, the latter revolving in such plate, and a beater is located at one end of such plate, such beater being adapted to revolve away from the main cylinder. In my device the cylinder does not turn in the plate; but

the latter being located as stated. all dust and dirt can pass out of its lower end. What I claim is- In a carding-machine, the doffer, the main,

cylinder, and the anti-suction plate, the latter of less length than a quarter of the circumference of the main cylinder, and located as described, in combination with the beater for the doffer, such beaterbeing placed above the anti-suction plate and revolved in the same direction with the doffer, as and for the purpose set forth.
