IMPROVEMENT lN MACHINERY FORLFEEDING CARDINGeENGI'NES.

Specification forming part of Letters Patent No. 37,304, dated January 6, 1863.

To all whom it may concern:

-Be it known that I, STEPHEN R. PARK HURST, of the city and State-of New York,

have invented, made, and applied to use a certain new and useful Improvement i nFeed-g chine, and,Fig. 2-is a plan of one side of the said feeding-table. 1 V

- Similar marks ofreference denote the same teeth'of. the table carry up said fibers, and the parts. i I

In carding and other machinery for workin g cotton, wool, and other fibrous material it is usual to supply a certain amount of the staple upon a given size of belt or apron formingthe feeding device in order that the fibrous bat or sliver may be uniform as delivered from the machine but these feeding belts or aprons are very liable to slip or become obstructed,

and the supply of fiberto the machine being lessened'or stopped causes the bat or sliver to break or be thinner at the particular part, which deranges the subsequent operations of spinning, 850.

The nature of my said invention consists in a rotary feeding table formed of a cylinder covered with teeth, and on which the-material is distributed from a hopper and evened by hand. I also employ a series of toothed rollers in combination with this feeding-table to open the locks of wool previous to their being taken by the cleaning or carding machinery. By this device I am enabled to supply the fibrous material with greater uniformity than by the aprons heretofore employed, and there i is less risk of the supply of fiber to the machine being arrested or checked, and the fibers are opened, loosened, and separated by a slow movement, that prevents the injury to the cotton or wool by the-pickers, breakers, or cleaners heretofore employed. Y

In the drawings, gis my rotary feeding-table mounted on the shaft 1, and said table'is revolved by means of gearing or any suitable mechanism.

h is an inclined board forming a hopper.

against the side of this cylindrical feeding-ta ble,-and curved side pieces, is, prevent the fibers falling ofl' at-the ends of the cylindrical feed- .--ing-table.i The periphery of this cylindrical rotary feeding-table is divided by means of blocks, pins, or similar devices (shown at t t t) whereby the operator on attendant is enabled i has passed the hopper-board h the given amount of fibrous material is placed on said board and distributed along the same. The

attendant sees that the mass is evenly distributed between this indicating-block i and the next one,which is easily done, as the fibers restupon said cylindrical feeding-table, and

then the operation is repeated by adding the given amount of fibrous material again into the hopper.

Z is a roller that presses the fibers to the teeth on the. cylindrical table, and this roller may receive an end movement, asiit revolves by means of a cam, and stationary stud or other suitable device by which the looks or bunches of fibrous material may be spread transversely of the table, causing the mass to be presented to the cleaning 'or carding machinery in a uniform bat. The fibers might be taken off the feed-table g by a pair of feed-rollers to the'or-- device would not fully carry out my invention,

by means of which the feed-rollers are dispensed with and theircompressing action on the fibers avoided. I provide, therefore, the toothed rollers or cylinders n and 0, which take the fibers from the teeth of therotaryfeeding-table, the cylinder 0 entirely cleaning the teeth of said table and being itselfcleaned by the cylinder at. This operation opens, combs, and partially cards the fibers Without liability to cut or break them, as the motion is slow.

a is the ordinary licker-in to the cardingcylinder 0 on the shaft b, and d e represent the usual workers, and f the doft'er. The opening, combing, and loosening operation on the wool or other fiber is still more promoted by the cylinder m, that acts between the cylinder a and n to separate any-locks or bunches of fiber and open them; and said cylinder m also removes surplus fibers from the roller 1. these means the fiber is in a proper condition by the time it reaches the portion of the machine adapted to cleaning or carding, so. that f The teeth on the respective'rollers and cyl inders may be'made of wire, or in any usual 1 p, traveling on rollers q q, and carrying crossrods or scrapers, that draw the fibers along over a screen or netting r to the said cylindrical feeding-table g. The dirt falls away through the netting r, and the fiber is taken by the teeth of the feeding-cylinder g and ear ried up against the curved guards and mentered into the carding-machine, thus eflecting a saving of the said fiber and rendering unnecessary the operations now resorted to for saving this-fiber and returnin it tothe carding-machine'.

-I 'do not claim a series of toothed cylinders. or rollers acting with the cardin g-cylinder,

as in the patentof Jeptha Dyson, December 6,1859; but

What I claim, and desire to secure by'Letters Patent, is v 1.. The cylindrical rotary feeding-table g, to supply the fibrous material to the cleaning or carding machine, substantially as specified.

' 2. The roller Z, in combination withthe said cylindrical rotary feeding-table g, for the purposes and as specified. Y

3. The belts p p, screen r, and curved guard s, in combination with the said cylindrical rotary feeding-table g, for the purposes and as specified.

4. A series of toothed cylinders, in combination with the toothed feeding -table, for opening, combing, specified.

In witness whercofl have hereunto set my signature this 10lh day of September, 1862.
