Application filed. July 22, 1915; Serial No. 41,315.

To all whom *z'zfmayconcern: I

Be it known that I, ALBERT H, MORTON, a citizen of the United States, residingvat' Lowell, in the county of Middlesex and State of Massachusetts,Lhave invented certam new and useful Improvements in Garding-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which appertains to, make and use the same.

The present invention relates to an improvement in carding engines.

The improvement in carding engines,

illustrated and described in my co-pending application, Serial No. 7,923, contemplated specifically the application of the driving power to the top flats within theiperiphery of the top fiat disks and at the top only of, the disks so as to cause the top flats to be adapted for new work.

It is the object ofthepresentinventionto" provide a construction and arrangement of parts which is especially adapted'for incorporation in existing machines, and which will enable the vabove improvement to be readily and conveniently applied to such machines at a minimum expense, and without change in the top flat chains or in the positions of the sprocket shaft and stripping comb or in the driving connections for the shaft and comb.

To these ends the invention consists in the features of construction and combinations and arrangements of parts hereinafter described and particularly defined in the claims.

In the accompanying drawing illustrating the preferred form of the invention Figure 1 shows a portion of the main cylinder, the top flats, the top flat chain sprocket and associated parts, and Fig. 2 is a vertical section of a part of the bracket, the eccentric, the disk, and the sprocket.

The illustrated embodiment of the inven- The construc-' tion therein lllllStlZLtGCl, however; was only,

manner with the top flat chain 10, which flats are driven by the sprocket wheel 11 mounted upon the sprocket wheel shaft" 12 and held against relative movement thereto by the key 13. The top fiat disk 1% is rotatably mounted between the bracket 15 and the sprocket 11 upon an eccentric 16 supported upon the sprocket wheel shaft,

and held from rotation by the pin 17 by which the eccentric is secured to the bracket 15. The eccentric 16 is provided with a shoulder or flange 18 which engages one side of the hub of the top fiat disk. The other side of the hub of the top flat disk engages the hub of (the sprocket .wheelll. These two parts, therefore, maintain the top flat disk The traveling flats 8 are articulated in the usual,

from the endwisemovement on the sprocket wheel shaft. It will be observed that the top ii at disk let supports and moves with the top flats, and at a difierent rate of surface speed from that of the pitch line of the top fiat sprocket 11. The only changes necessary to be made in the carding engine for the pur= pose of adapting the use of this invention" thereto is to drill a hole in the bracket 15 to receive the pin 17 to apply the new partsthe sprockets, eccentrics and the disks. This makes, therefore, a very inexpensive construction for changing over existing Ina-'- chinesto embody the invention of the said application Since in changing over existing machines the old top fiat chains are retained, the pitch of the new sprocket 11 will be determined by the pitch of these chains, while its diameter must be such that its lower portion will clear the lugs on the flats. The eccentric 16 is so constructed and arranged that its center is in, or substantially in, a line bisecting the angle between a line passing through the centers of the sprocket shaft and main cylinder and a line passing through the center of the sprocket shaft and the point of operation of the stripping comb. This construction. and arrangement of the eccentric enables the disk to be so proportioned thatthe position of its surface at the line passing through the centers of the cylinder and sprocket, and at the point of operation of the stripping comb, will prac- 1 tically coincide with the position of the surface of the old disk at these points, so that the top flats will be accurately positioned to cooperate with the main, cylinder at the point where the flats leave the cylinder, and

to cooperate. with the old stripping comb.

The disk is made of such a size that its surface will coincide with the surface of the old disk at the points above referred to, and will also so support the top flats'that the pitch line of the lugs on the flats will properly coincide with the pitch line of the sprocket at that portion of the disk surface which coincides with the driving. portion of the sprocket. With the disk thus proportioned and mounted upon an eccentric constructed and arranged as described, the surface of the top flats will not only be in practically the same position at the points referred to as when supported upon the old disk, but

will. also betraveling in practically the same directions at these points, and thus the proper cooperation of the old top flats with the old main cylinder and stripping comb is claimed is:

1. A carding engine, having, in combination, a main cylinder, revolving top flats, a top fiat sprocket and shaft, a disk for supporting the top flats, a bracket, an eccentrio pinned to the bracket and affording a support for the top flat disk eccentric to the top flat sprocket shaft.

2. An eccentric for use in reconstructing carding engines provided with a hole to re ceive the pin by which the eccentric is pinned fast tothe bracket, and an eccentric surface to receive the top flat disk.

3. An eccentric for use in reconstructing carding engines provided with a hole to re-.

hole to receive the sprocket wheel shaft of thecarding engine, and a surface to receive the -top flat disk, combined with a device for securing the eccentric to the bracket of a carding engine. 7

5. Mechanism for reconstructing top flat drives of carding engines having top flat supporting disks and top flat sprockets, comprisingtop flat driving sprockets adapted to be secured to the sprocket shaft of the machine, and of a size to engage the top flats near the top only of the top flat disks, top flat disks and eccentric bearings for the top flat disks constructed to support the disks with their surfaces at the point where the top flatsleave the main cylinder and at the point of operation of the stripping comb substantially coincident with the positions of the surfaces of the old disks at these points.

6. A carding engine, having, in combination, a main cylinder, a stripping comb, revolving top flats, a disk for supporting the top flats, a sprocket for driving the top flats,.and an eccentric bearing for the disk having its center substantially midway between a line passing through the centers of the sprocket and main cylinder and a line passing through .the center of the sprocket and the point of operation of thestripping comb.
