CARD-GRINDING MACHINE.
SPECIFICATION forming part of Letters Patent No. 278,6081'dated May 29, 1883.
Application filed April as, 1883. (so model.)
To all whom it may concern Be it known thatI, CHARLES SCHREBLER,'0f
Ohambersburg, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Card-Grinding Machines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in card-grinding machines, the object of the same being to provide a device whereby the cardteeth are ground to a needle-point without the necessity of moving the grinding-wheel longitudinally, or the carding cylinders laterally; and with these ends in view my invention consists in a card-grinding cylinder coated with emery and provided with two or more intersecting spiral grooves.
In the accompanying drawings, Figure 1 is a perspective view of my improved cylinder,
and Fig. 2 is a longitudinal sectional view of the same.
A represents a cylinderof any desired diameter and length, provided at opposite ends with the trunnions a. This cylinder can be made of metal or wood, and is provided with the spiral grooves B and 0, running, respect ively, in opposite directions around the cylinder. 1f desired,'more than two grooves can be employed, m main object being to convert the periphery of the cylinder into a number of diamond or other angular shaped blocks, the outer surface and the sides thereof, if desired, being coated with emery pebbles, which latter can be applied directly to the surface of the cylinder; or emery-paper can be cut into the desired shapes and secured to the cylinder. The grooves B and G are ofsufficient depth to allow a free circulation of air, which serves to keep the teeth cool and prevent the temper from .bein g taken therefrom. Besides peri forming the functions above enumerated, the
grooves also serve as dustreceptacles, into which thedust and dirt from the card teeth falls and from which it is discharged by the rotation of the cylinder. The cylinder is adapted to be mounted in a suitable frame, and be surrounded by the workers, strippers, and licker-in, all of which, together with the cylinder, having rotary motion imparted thereto, the latter, however, moving much more rapidly than the carding-cylinder. The top-flats can, if desired, be secured in the same frame with the carding-cylinder, and instead of havin g a rotary motion imparted thereto are reciprocated in guides tangential to the emerycylinder, so as to bring all the teeth in contact therewith. The teeth of the carding-cylinder are adapted to bear against the periphery of the emery-cylinder, and as the latter is revolved (in a direction contrary to the revolution of the cardingcylinders) the points or ends of the diamond or other angular shaped blocks enter between the teeth and separate them slightly. This slight separation causes the teeth to incline sidewise, and consequently expose the side edges of the points of. the teeth, as well as the back thereof, to the action of the emery pebbles, thereby performing the same function as the longitudinallyreciproeating wheel, only in a much shorter space of time. l
It is not necessary that the cylinder proper should be grooved, as the result would be the same if leather or other suitable blocks coated with emery were secured to the cylinder, with spaces between theseveral blocks, which spaces would perform the same function as the grooves; and hence it is evident that I do not confine myself to the exact construction shown and described, but consider myself at liberty to make such changesand alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. A card-grinding cylinder coated with emery and provided with two or more intersecting spiral grooves, substantially as set forth.
2. A card-grinding cylinder the surface of i which is coated with emery and divided into diamond or other angular shaped blocks, snbstantially as set forth.
' 3. A card-grinding cylinder the surface of which is coated with emery, and provided with two or more intersecting spiral grooves, which latter divide the surface thereof into diamond or other suitable shaped blocks, substantially as set forth.
In testimony whereof I have si gned this specification in the presence of two subscribing witnesses. I
. CHARLES SOHREBLER.
Witnesses: J noon B. HOLTZWORTH, A. A. HUBER.
