ATTACHMENT FOR CARDING-MLACHINES.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed December 24, 1913. Serial No. 808,536.

To all whom it may concern Be it known that I, THOMAS ll-Hnnonn, citizen oi the United States, residing at W inooski, in the county of Chittenden and tate of Vermont, have invented certain new and useful Improvements in Attachments for Carding-Machines, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to improvements in attachments for carding machines.

The object of my invention is to provide an attachment for a machine of thls character adapted to gather the wool-fiber after it has been combed by the dofi'er-comb, and to convey it to 'one side of the machine and v time partially twist it so that it will be heldtogether in a uniform sliver ready to be presented to the card finisher.

Another object of my invention is to provide a simple, cheap and effective attachment of this character having certain dei of construction and operation herein- .riioer more fully described.

In the accompanying drawings'Figure 1 showing my attachment applied thereto. Fig. 2 is a side view of Fi 1, looking in the direction of the arrow 0 Fig. 1. Fig. 3 is an end view of Fig. 2, looking in the direction of the arrow of Fig. 2. Fig. 4 is a side elevation showing in detail the drawing roll and the rotating tube. Fig. 5 1S :1 vertical sectional view partly broken away and taken on the line A-B of Fig. 1.

Refer-rim now to the drawings, 1 represents the frame of my improved carding machine which is provided with the usual dofler-roll 2 and the dofi'er-comb 3, all of which is of the usual structure and needs no further description. Secured to the dofi'ercomb 3 is a board l adapted to convey and keep the fiber down upon the belt carrier 5, as will be hereinafter more fully described. Carried by the shaft 6 of the dofier-roll 2 is a sprocket wheel 7, over which passes a chain 8, the said chain passe over a sprocket 9 carried by a shaftlt). an said shaft can ries a stepped pulley 11.

The dotler-comb 3 tion. Below the lower end of the board 4 is a belt carrier 12 extending the half length of the doffer roll 2, and upon which new of a carding machine.

is operated in any desired manner and needs no further descripthe fiber is deposited as it is combed by th doifer comb 8. This belt carrier, as shown in Fig. 2 of the drawing, is of the endless belt type and the pulley 12, over which the belt-carrier passes, is provided with a sprocket 13, over which the chain 14 passes.

The said chain extends to the right of the machine and passes over a sprocket 15, mounted upon the shaft 16 of the drawingroll 17. This drawing-roll, as shown, is at one side of-the dofier roll 2 and in a horizontal plane approximately that of the upper face of the endless carrier'5. This shaft 16 is driven in the usual manner and needs no further description. The rotation of this drawing-roll shaft 17, through the medium of the sprockets 13 and 15 and chain 14:, rotates the pulley 12 over which the endless conveyor passes, by means of which the same is caused to deliver and convey the fiber as it is combed from the dofi'er-roll. Below the drawing-roll 17, is a second drawing-roll 18. These rolls are provided with openings 17 and 18 respectively, registering with the opening through which the sliver passes, as willbe hereinafter more fully described. Arranged at the right ofthe belt-carrier 5, is a taper-roll 19 having the spiral grooves 20 in its periphery and which is adapted to receive the fiber from the belt carrier and twist and roll the sliver, whereby a knotted or irregular "fiber may be more readily straightened out and gathered before going to the finisher. The taper-roll 19 is carried by a shaft 21' having a pulley 22 over which passes a belt 23, which also passes over the pulley 11, and by means of which the taper-roll is continuously driven. At the end of the taper'roll 19 is the rotating tube 24, which is driven by. a belt, 25, which in turn is driven by the same'mechanism that drives the shaft 16 of the drawing roll 17 and needs no further description. This rotating tube 24, as shown, is at a point on a line with the belt carrier adjacent the 100 inner periphery of thetaper-roll, whereby the sliver as it is twisted" by the ta er-roll passes through the rotating tube. an is ther twisted and passes from this rotating tube between the drawing-rolls, where it is 105 further compressed and passes from the machine in a comparatively compact sliver, so

that it can be readily handled in presenting it to the finishing machine.

Having thus described" my invention, 11o

what I claim and desire to secure by Letters Patent is- 1. The combination with a carding vInachine, of a carrier below the dofi'er-comb and a taper-roll having spiral grooves adapted to receive the fiber from the carrier and twist and convey it. to one side-of the machine. w

2..The combination with a carding machine, of an'endless carrier below the dofier comb, of a taper-roll having spiral grooves adapted to receive the fiber from the endless carrier and twist; and convey. it to one side of the machine.- v

of 'a'n endless conveyer below the dolfercomb, a taper-roll having spiral grooves in its periphery and adapted to receive the fiber from the endless conveyor and twist 3. "The combination of a carding machine,

and convey it to the side of the machine,

"and a rotating tube through which the sliver is forced by the-taper-roll.

The'combination with a carding machine, of an endless conveyer below the 'dotl'encomb, a rotating taper-roll having spiral grooves in its periphery and adapted to receive the fiber from the endless con-- vey er and twist and convey the fiber-to the side, a rotating tube adjacent the end of the taper-roll and through which the sliver passes, drawing rolls adjacent the rotating tube and between which the sliver passes, and means driven by the carding machine 3 operating the endless conveyer, the taperroll, ,the rotating tube and the drawingrolls;

5. chine, a horizontally arranged endless conveyer below the dofler-comb an obliquely arranged taper-roll adjacent the end of the endless conveyer and having spiral grooves in its outeriperiphery, means for rotating the taper roll; and operating the endless Copies of this patent may be obtained for The combination with a carding ma- -.conveyer, a rotating tube adapted to receive the sliver from the taper-roll and drawingrolls receiving the taper-roll from the rotating tube, substantially as shown and described.

6. The combination with a carding ma-.

chine, of an endless conveyer below the taper-comb, means for operating said endless conveyer, a taper-roll receiving the fiber from the ,endless conveyer and having grooves in its outer periphery adapted to' twist and convey the fiber to one" side of the machine, a rotating tube adapted to receive the sliver from the taper-roll, means for rotating the tube and rotating the drawingrolls receiving the sliver from the rotating tube. v

7 .The combination Wfith a carding machine, an endless belt oonveyer horizontally arranged below the doft'erecomb, means operated by the machine fordriving said endless conveyer, a taper-roll adjacent the end of the endless conveyer and obliquely arranged and having spiral grooves in its periphery and adapted to twist and convey the fiber as it passes from. the endless conveyer, a rotating tube adjacent the opposite end by the taper roll through which v the sliver passes from the taper-roll,'means driven by I THOMAS D. HOLDEN.
