CARDING MACHINE Filed March 21, 1940 INVENTOR Fred schiesskr y v W ATTORNEYS Patented May 27, 1941 T OFFICE CARDIN G MACHINE Fred J. Schiessler, Cumberland, Md, assignor to Celanese Corporation of America, a corporation of Delaware Application Illa-r011 21, 1940, Serial No. 325,143

3 Claims.

This invention relates to carding machines, and relates more particularly to an improvement in roll top carding machines.

In roll top carding machines, as heretofore commonly constructed, no provision was made for controlling the air currents set up by the air discharged from the face of the cylinder and the strippers when the machine is in openatiom This air striking the workers, the strippers or the cover sets up whirling air current which rolls into lumps or balls some of the loose fibers. Many of these lumps or balls or fibers pass through the carding machine and get in the yarn as slubs.

It is an important object of this invention to provide simple, efficient and inexpensive means for substantially entirely preventing the discharge of air and loose fibers from the face of the cylinder and strippers whereby whirling air currents are effectively eliminated.

Another object of this invention is the provision of plates which are of such configuration and which are so positioned with respect to the carding machine as to prevent the formation of whirling air currents.

Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description.

Referring to the drawing, wherein the preferred embodiment of my invention is shown:

Fig. 1 is a fragmentary view of a carding machine showing the plates of my invention installed therein,

Fig. 2 is a detailed view in perspective of one of the plates employed in accordance with this invention, and

Fig. 3 a detailed view in perspective of another form of plate employed in accordance with this invention.

Like reference numerals indicate like parts throughout the several views of the drawing.

Referring now to the drawing, the reference numeral 4 indicates generally the frame work of a roll top carding machine having the usual bearings for the main carding cylinder 5 and the doffer 6. Cooperating with the main carding cylinder 5 are the usual pairs of workers and strippers, the workers being indicated by the reference numerals l, 8 and 9, and the strippers by the reference numerals I I-, I2 and [3. The pairs of workers and strippers are enclosed by the usual cover 14.

According to this invention, the carding machine is provided with means for preventing the rotation of the main carding cylinder 5 and the strippers ll, l2 and [3 from setting up whirling air currents and forming lumps and balls of fibers in the pockets between worker I [and stripper I2, worker 8 and stripper I3 and worker 9 and side wall I5 of the cover [4.

In carrying out this invention plates of suitable shape are positioned in the pockets where the w-hirling air currents are normally produced. In Fig. 2 is shown one such plate generally indicated by the reference numeral 16 having a portion I! which is adapted to be placed over that part of the carding cylinder between the worker and the stripper and which is slightly curved to conform to the curvature of the main carding cylinder surface. Integral with one longitudinal edge of the portion I6 is a shield l8 bent into the form of a reversed-S which is adapted to fit over and around a substantial portion of the stripper and a portion of the worker. The other longitudinal edge is bent upon itself to form. a tube l9, the purpose of which is to receive a rod for holding the plate in the desired position with respect to the carding cylinder, stripper and worker. The rod is, of course, suitably attached to the framework of the carding machine.

Fig. 3 shows a plate similar to that shown in Fig. 2 except that the reversed-S shield-is omitted, since such a shield is not essential in the position where that particular plate is employed, i. e. between worker 9 and the side wall [5 of the cover l4.

It is to be understood that the foregoing detailed description is merely given by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

1. In a roll top carding machine, the combination with a main carding cylinder, of a plurality of stripper and worker combinations, of a baffle plate adjacent to the surface of said carding cylinder between said stripper and worker combinations for preventing the formation of air currents, said baffle plate having a portion curved. to conform to the curvature of said carding cylinder and another portion curved to conform to the curvature of a stripper, and a cover over said stripper and worker combinations.

2. In a roll top carding machine, the combination with a main carding cylinder, of a plurality of stripper and Worker combinations, of a bafile plate adjacent to the surface of said carding cylinder between said stripper and worker combinations for preventing the formation of air currents, said baffle plate having a portion curved to conform to the curvature of said carding cylinder and another portion curved to conform to the curvature of a. stripper and extended to cover a portion of a worker, and a cover over said stripper and worker combinations.

3. A baflle plate for preventing the formation of air currents in roll top carding machines having a main carding cylinder comprising a plate having a portion curved to conform to the curveture of said carding. cylinder, said plate having one longitudinal edge bent upon itself to form a tube and the other longitudinal edge having integral therewith a. shield in the form of 'a reversed-S in vertical cross-section.
