WILLIAM HENRY STAYNES, OF LEIbESTER, ENGLAND.
BUFFING-ROLL.
Specification of Letters Patent.
Patented June 11, 1912.
Application filed ()ctober 20, 1911. Serial No. 655,752.
To all whom it may concern.
Be it known that I, WILLIAM HENRY STAYNES, a subject of the King of Great Britain, residing at Leicester, in the county of Leicester, England, have invented certain new and useful Improvements in Buffing-R-olls, of which the following is a specification.
This invention relates to improvements in machinery employed in the manufacture of leather.
The invention consists of a roll or cylinder provided with a series of ribs having abrasive working faces particularly adapt ed for use in what is known as the bufling operation 2'. e. of removing by abrading the grain side of the hide or skin. Such a roll or cylinder may be made of wood with the ribs or bars out or otherwise formed on the face thereof and the face of the said ribs or bars may be covered with abrasive material such as sandpaper secured thereon by cement or other suitable adhesive, or in any other convenient manner. For the bufling operation hereinbefore mentioned the ribs or bars are arranged in series converging to a point approximating a V so that as the roller revolves the apices of-the bars act on the center of the hide or skin and the divergence of the bars gradually buffs or abrades the skin toward the'outer edges of the same.
One form of a bufling roll according to this invention is illustrated in the accompanying drawing, wherein Figure 1 is an elevation of the roll. Fig. 2 is a section on the line a-b of Fig. 1, and Fig. 8 is an end view.
Like parts are designated by the same reference characters in all the figures.
Referring to the drawing, 1 is the roll or cylinder which may be suitably attached to a spindle 2 mounted and rotated in any convenient manner. The roll 1 may be made of wood, metal or any other suitable material such for example as carborundum or solid emery, and is provided with a series of ribs or bars 3 having abrasive or working faces 1.
As shown in Fig. 1, the ribs or bars 3 are, for the buffing operation, arranged in series converging to a point approximating a V, the apices of the said V shaped bars being located approximately in the middle of the roller so that as the latter rotates, in the direction indicated by the arrow in Fig. 1, a divergence of the said ribs or bars 3 in opposite lateral directions from the center outward will take place and thus the hide or skin will have imparted thereto a buffing or abrading operation which is ef fected in a direction from the middle toward the outer edges of the same. The ribs overlap each other at the middle of the roll and the overlapping terminals closing the ends of the channels between the ribs are narrowed as shown. By this means the abrading surface is rendered continuous at the middle of the roll at its middle portion, but in a zigzag direction thus making the abrading operation more effective than if the overlapping were omitted, While, by reason of the terminals of the ribs being diminished, the abrading action at the middle of the roll'is equalized with that of other portions.
The ribs or bars 3 may be integrally formed with the roll 1 or they may be at tached to the face of the roll in any suitable manner. The working faces 4: of the ribs 8 may be covered with abrasive material such as sandpaper secured thereon by cement or other suitable adhesive, or in any other convenient manner. If desirable however, the ribs or bars 3 may be Without an abrasive covering such as just described, this being especially the case when the ribs or bars are formed upon a roll or cylinder of carborundum or solid emery. Other arrangements of the ribs or bars 3 on the roll 1 may be employed although they may not be so suitable for the operation mentioned, but nevertheless may be convenient for other analogous operations.
What I claim then is V r A bufling roll having projecting ribs on its surface with abrasive Working faces, said ribs being arranged in series convergmg to a point approximately a V so that as the roll rotates in the direction of the apices of the ribs the latter, by divergence from their apices, act upon the work from the center thereof laterally outward toward the edges Copies of this patent'may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. G.
