`PATENT OEEIcE.
JARVIS HOWE, OF MILFORD, MASSACHUSETTS, ASSIGNOR TOTHE SHOE- MACHINERY MANUFACTURING COMPANY, OF CONNECTICUT.
IMPROVEMENT IN CVLINDERS FOR SOLE-B-UFFING MACHINES.
Specification forming part of Letters Patent No. 136,727, dated March 11, 1873.
To all whom 'it may concern:
Be it known that I, JARVIS HOWE, of Milford, in the county of Worcester and State of Massachusetts, have invented an Improvement in Cylinders of Sole-Buftng Machines, &c.; and I do hereby declare that the following, taken in connection .with the drawing which accompanies and forms part of this specification, is a description ot' my invention sufficient to enable those skilled in the art to practice it. v
The invention has particular reference to the manner of conning sand-paper to the circumferential or peripheral surface of the cylinder or roll of a sand papering 'or buffing machine especially used in bufting the soles of boots and shoes.
In my invention the cylinder has a central mandrel or shaft, upon one end ofl which is the band-pulley. Encompassing this shaft is the roll or cylinder, made in halves, covered by felt or other suitable soft material and sand-paper, the felt and sand-paper being each, preferably, made in one piece, and the two parts of the cylinder opening and closing upon the felt as a hinge, while the edges of the sandpaper or paper and felt lap in upon the inner faces of the half-cylinder, to which they may be fastened by spurs, but are, preferably, fastened by spring-wires, the method of fastenin g by the wires forming one part of my invention. From opposite ends of each half of the cylinder or roll extend half-cones, or conicfrustums, the whole cone formed by the halves at one end slipping endwise into a conical socket near one end of the shaft; while over the cone upon the opposite end works a conically-socketed nut or nut-rin g, which turns on a screw-thread cut on the shaft, this nut, in connection with the socket for the cone at `the opposite end, forming la clamp, by which the half-cylinders are held tightly together and upon the mandrel to form the continuouslysurfaced sand-paper roll or cylinder.
It is in this method of fastening the halfrolls together and upon the shaft that my invention primarily consists, a detail of the invention relating to and consisting in an improved method of fastening the sand-paper to the periphery of a whole wheel, when the wheel is made narrow or thin to enter small hollows or concaves, which cannot be reached by long cylinder-surfaces, like that of the main cylinder.`
The drawing represents a roll embodying my construction.
Figure l shows the roll in plan and section. Fig. 2 is a cross-section of it. Fig. 3is a view of the open half-rolls.
a denotes the shaft or mandrel, upon which is the cylinder or roll, composed of the halves b c, said halves encompassing the shaft, and being covered by the felt or other jacket d that makes the bed for the sand-paper e, the paper and felt preferably extending entirely around the cylinder,fwith no break except at the edges f g that lap over upon the iiat faces x of the half-rolls. The felt is tacked or otherwise directly fastened tothe body of the roll; and the centralpart, on and adjacent to the line h h, not only makes a hingel upon which the two halves of the cylinder open, but also forms a protection for the paper, so that the latter extends unbroken over the line h h. The lapping edges of the paper are held by springs i, the body of each of which is fastcned in the roll, while the end 7c extends over the edge of the paper, being held thereto by the. stress of the spring. By means of these springs the paper is held firmly, and cannot slip away, the extreme end or point of the wire being preferably bent and penetrating the paper. At each end of the cylinder are the halt'- cones l m, one cone entering the stationary socket a to clamp the halves together, and a concave nut, o, working on a screw-thread, p, cut on the mandrel, moving over the other cone to clamp its halves together, the nut o and socket n clamping the two halves tightly together and upon the cylinder, and enabling v them to be unclamped, opened, and removed without taking or starting the shait from its bearin g for renewal or application of the paper.
Rotation being imparted to the cylinder, the
cylindrical sand-paper surface serves to buff I the large and i'reelymanipulated surfaces brought against it, and, to enter the angles and small curves, a narrow wheel, q, is used. Upon this wheel is the peripheral sand-paper r, underlaid by the felt or other soft material.; and, to keep this paper in place, strong bowsprings s may be used 5 or springs, the opposite immediately beneath it, or forces it into the felt, so that the fastenin-gs, without the aid of tacks, are pressed below the cyliudrio or operating` surface of the sand-paper.
I claim- 1. The cylinder or rolls formed of the halves b, c, and having the sandpaper or abrasive cover e, the halves being held together and upon the roll by the socket a and nut-ring o thatencompass and clamp Iche cones lm, all substantially as shown and described.
2. The springs s, holding the sand-paper r by their stress, and pressing int-o the surfaces beyond the Working-surface of the cylinder, substantially as shown and described.
Executed this 7th day of January, A. D. 187 3.
JARVIS HOWE.
