UNITED STATES PATENT OFFICE.
HENRY HOLCROFT, OF MEDIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO D. T. GAGE AND H. L. MOULTON, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN DOFFING MECHANISMS FOR CARDlNG-MACHINES.
Specification forming part of Letters Patent No. 153,340, dated July 21, 1x74; application filed June 10, 1874.
To all whom it may concern:
Be it known that I, HENRY HoLouoET, of
Media, Delaware county and State of Pennsylvania, have invented certain Improvements in Carding-Machines, a means for operating the dofercomb, of which the following is a specification My invention consists in the arrangement of two eccentric driving-pulleys, to give a reciprocating motion to the doffer-comb. The object of my invention is simplicity, durability, and capabilityT of a high rate of speed, the working parts being` balanced.
Referring to the drawings making a part of this specification, Figure l represents the side of a'card with my improvement. Fig. 2 is a view of the double arm F. Fig'. 3 is a view ofthe eccentrics and part of the shaft E. Fig. 4 is a view of the pulley R and its stud.
Similar letters in the drawings refer to like parts.
I construct two eccentric grooved pulleys,
ywhich I fasten together, as shown in the drawing, Fig. 3, and then fasten to the shaft E. F is a double arm, with two slot-s, c c. In
these slots are placed the studs d, on which are placed small grooved pulleys R R. These pulleys may be made single, or in the form of a cone, as shown in Fig. 4. rlhe arm F is fastened on the end of the comb-shaft K. (See Fig. l.) S S are two round bands, which may be made of leather or cotton. A is the cylinder, D the dotier, and C the comb, which are constructed in the usual manner.
The operation is as follows: The shaft ofthe cylinder A, which is the first mover, communicates motion to the shaft E, on which are fastened the eccentric pulleysB B. The bands S S communicate to the pulleys R R', and the revolution of the eccentrics B B will give a rocking or reciprocating motion to the combshaft K and comb O. By adjusting the studs d. in the slots c a, the stroke ofthe comb may be varied.
A flat band may be used, if desired, in place of a round one.
I claimrIhe combination of the eccentrcs B Bf, bands S S, pulleys R R', arm F, and comb U, as described, and for the above purpose.
