IVILLIAM J. DONIGAN, OF AMSTERDAM, NE\V YORK, ASSIGNOR OF TWO- TIIIRDS TO JOHN K. STEIVART AND GEORGE A. CLARK, OF SAME PLACE.

CARDVING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 617,481, dated January 10, 1899. Application filed September 30, 1898.- Serial No. 692,283. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM J. DONIGAN, of Amsterdam, in the county of Montgomery, in the State of New York, have invented new 5 and useful Improvements in Garding Apparatus, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to certain improvements in carding apparatus; and the object is to provide simple and effective means to support the web or sliver while it is being combed from the doffer-roll and moved to one side and to assist in such movement. Heretofore various devices have been used to support and to prevent the sliver from dropping down, such as boards covered with tin, also tin cylinders revolving under the sliver, and other supports which were mounted on the floor beneath the sliver to give it some support, but these being stationary cause a drag on the sliver after it is combed down from the doffer-card, while with my invention the sliver is supported and moved along easily without injury to the same.

To this end my invention consists in the combination of the doffer-rolLthe rockingbar, and the doffer-comb carried and operated thereby with a plurality of fingers extending from the rocking bar and projecting below the comb in close proximity to the doffercard.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a top plan view of the rocking bar, comb, and fingers. Fig. 2 is a vertical sectional view of the same, taken on line new of Fig. 1; and Fig. 3 is afront side elevation of the devices and shows the sliver supported on the fingers while it is carried to one side preparatory to being twisted slightly, as usual, and wound upon a spool.

Referring specifically to the drawings, A is the rocking bar, and B is the cam-box containing the cam and other mechanism for rocking or oscillating the bar in the usual and well-known manner. Any suitable and well-known means for rocking the bar A may be employed, and as these are well known and form no part of my invention it will not be necessary to sho w in detail or describe specifically the same.

13 is a double pulley on the cam-box shaft to be driven by a belt from some other revolving shaft in the machine. The said rocking shaft extends parallel with the doffer-roll and lies substantially in a horizonal plane extending through the shaft of thedofferroll 0. (Shown partially in Fig. 2 ofthe drawings.)

' D is the doffer comb or blade, of the usual form, provided with teeth on its lower edge to engage the card on the doffer-roll C and comb therefrom the to form the sliver.

fibers collected thereon The said comb is parallel with the rocking shaft A and is secured thereto by a series of rods E, arranged parallel side by side and extending through both the rock ing bar and comb.

The ends of the rods are riveted or otherwise secured in the bar and comb-blade. Extend in g downwardly through passed through rolls, and a revolving tube (not shown) which t is wound on a spool.

wists the same before it The sliver e is indicated in both Figs. 2

and 3 as supported the comb is rapidly on these fingers F. As oscillated or raised and lowered in its operation, the fingers being also secured to the rocking bar are also rapidly raised and lowered, thus assisting --in moving the sliver while supporting it, or at least in supporting i it is moved easily b t in such a manner that y other means and not injured or broken during such movement. The fingers are shown in an angular shape and with their free end portions lying parallel or nearly parallel with the rods E above; but I do not desire to be limited to the precise form of the fingers shown in the drawings,

from my invention.

'nor to their junction with the rocking bar, for'these may be varied without departing The fingers are shown with their ends riveted in the bar; but they may be secured rigidly or adjustably therein in any suitable and well-known manner.

The broken lines in Fig. 2 indicate the different positions and range of movement of the rocking bar, comb, and fingers.

Having described my invention, what I claim as new, and desire to secure byLetters Patent, is

1. In a carding apparatus, the combination of the doffer-roll, the rocking bar and the doffer-comb carried and operated by the rocking bar, with a plurality of fingers extending from the rocking bar, and projecting below the comb in close proximity to the doffercard, substantially as described and shown.

2. In a carding apparatus, the combination of the doft'er-roll, the rocking bar and the dofl'er-comb carried and operated by the rockin g bar, with a plurality of fingers connected to and operated by the rocking bar, said fingers extending in close proximity to the card on the dolitcr-roll, and with their free ends lying below the said comb and in. substantially the same plane, as and for the purpose described.

3. The combination of the do'lfer-comb, the rocking comb-shaft, a plurality of rods connecting the comb with its shaft, and bent fingers secured at one of their ends to the rocking bar, and having their free ends lying in a plane below the plane of the plurality of rods, and extending below the teeth of the comb, and adapted to be moved simultaneously with the comb, as and for the purpose described.

In testimony whereof I have hereunto signed my name.

XVILLIAM J. DONIGAN. Vitnesses:
