JOSEPH S. DRONSFIELD, OF OLDHAM, COUNTY OF LANCASTER, ENGLAND.
CARD-GRINDING ROLLER.
SPECIFICATION forming part of Letters Patent N 0. 404,608, dated June 4, 1889.
Application filed April 5, 1887. Serial No. 233,775. (No model.) Patented in England June 5, 1886, No. 7,553-
TO all whom it may concern:
Be it known that I, JosEPH STANDRING DRONSFIELD, machine-maker, a subject of the Queen of Great Britain and Ireland, re-
siding at Oldham, county of Lancaster, Eng- Y land, have invented certain Improvements in Card-Grinding Rollers, (for which there has been granted a patent in Great Britain, No. 7,553, dated June 5, 1886,) of which the following is a specification.
My invention relates to the rollers which are used in the grinding of the wire cards on the cylinders andv doffers of carding-engines. These rollers are made of metal and have thin sheet-metal or tubular shells, which are secured to cast-metal ends. In some cases these rollers are covered with a ribbon or fillet of woven material which has been coated with emery, the fillet being wound spirally around the roller from end to end. It is to this description of roller that my invention relates. I secure the ends of the fillet by means of clamps, and I form the roller ends in two parts screwed together, recesses for the reception of balancing-weights being formed in one part and being concealed when the two parts are secured together.
My invention is illustrated by the accompanying drawings.
Figure 1 represents a section of one end of the roller, the section being taken on and in the direction of the axial line. Fig. 2 is a View of one end of the roller, with the part which is secured to the axle removed. Fig. 3 is a corresponding view of the other end of the roller.
The tubular shell a of the roller is made of sheet metal or of thin metal, or in the form of a thin tube. Each end of the roller is in two parts, I) and c. The part b is annular in form and is turned to fit inside the end of the shell a and to fit the part c. The latter is in the form of a flanged boss and is bored to receive the axle d, upon which it is made to be a tight fit and upon which it is forced. The flanged boss 0 is formed with a rim 0, which is turned to fit inside the ring I). The two parts are secured together by means of screws 6 6. I11 the ring I) are formed recesses f f to receive weights, which are added as may be required, to balance the roller and to make it run steadily at a high speed. One of these weights is seen at g in Fig. 1. When the rolleris put together, the flanged boss 0 conceals the balanced weights and prevents their removal. The fillet, covered with emery, isindicated by h. The ring I) at the end of the roller shown in Fig. 2 is formed with an illclined slit 2', and with a fiat place upon which the end of the fillet can be clamped. The end of the fillet is passed through the slit and is secured by means of a clamping-plate k. A screw Z passes through the clamp and the fillet and into a tapped hole in the ring and causes the clamp to tightly grip the fillet end. The fillet, having been wound spirally around the roller, is secured by means of a second clamp to the other end of the roller, which is represented in Fig. 3. This end of the roller is provided with three slits and three flats, and is drilled and tapped 'at three places to receive the screw Z. The reason for this is that when the fillet is wound upon the roller it is uncertain at what point of the roller end the end of the fillet will run out. The end of the fillet is passed through-the one slit of the three which is most conveniently situated, and is clamped in the same manner as the other end of the fillet. I do not confine myself to the three slits, but would prefer to provide more than three rather than less. The number shown is what I have found to be suitable.
What I claim as my invention is 1. The combination of the card-grindin g roller, its axle, and the ring 1), adapted to the end of the roller, and having recesses f and slit 2', with the clamp at the slit, and the flanged boss 0, fixed to the axle and secured to the said ring, all substantially as set-forth.
2. The combination of the card-grinding roller, its axle, and the ring I), adapted to the end of the roller, and having recesses ffor weights, with the flanged boss 0, secured to the axle and to the said ring and closing the said recesses in the latter, all substantially as specified.
3. The combination of the card-grinding roller, its axle, and the ring 1), adapted to the end of the roller, and having a slit 1', with the clamp at the slit, and the flanged boss fixed on the axle and secured to the ring, substantially as set forth.
4. The combination of the card-grinding IntestilnonywhereofIhavesignedmynmne roller, having at one flanged end thereof ato this specification in the presence of two subslit 1', with a spirally-wounkjl fillet, the end of scribing witnesses. which passes through the slit, and a clamp JOSEPH S. DRONSFIELD. ing-plate 7a, to bind the end of the fillet to the flange of the grinding-roller, and ascrew Zto secure the plate, substantially as specified.
