U NITEn STATES PATENT OFFICE.
HENRY 1V. BRETT, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN SAND-PAPER ROLLERS.
Specification forming part of Letters Patent No., 145,392, dated Decemhe r 9, 1873; applifation filed November 12, 1873.
To all whom it may concerm.
Be it known that I, HENRY W. BRETT, of
Boston, Suiolk county, State of Massachu setts, have invented an Improved Sand-Paper Roller, of which the following is a specifica tion:
This invention is more particularly designed for sandpaper-covered rollers, to be used for sand-papering boot and shoe soles; and it relates wholly to the conii'neinent or attachment ot' the sand-paper to and about the body ofthe roller.
Under the invention,tlie roller is wrapped with the sand-paper, and then its two edges are passed through a common longitudinal slit of the roller and made secure in and between two claniping-jaws that are located within the roller, and are there arranged to be adjusted to tighten the saiid-paper about and to closely and firmly confine it to the roller-body, and to be then set or held against accidental movement or slip.
Q' In the accompanying plate of drawings a sand-paper roller constructed according to this invention is illustrated, Figure I being partly a side view and partly a central longitudinal vertical section; Fig. 2, an end view; and Fig. 3, a cross-section in plane ot' lille a' m, Fig. l.
In the drawings, A represents the rollerbody, which may be made of wood, cast-iroii, or any other suitable material. a is a slit running lengthwise and opening to the inside of the roller, which is, to some extent, hollow or open; B B2, two clamping-jaws. The jaws B B2 are carried by a common block, C. The jaw B is lined to the block C, and the jaw B2 is free to be set against or otf from the tixed jaw B, and each end of the two jaws is provided with a screw-bolt, I), which passes loosely through the free jaw B2, and screws into the iixed jaw B. The jaws B B2 and their carrier C are located within the open body ot' the roller, and they extend from end to end thereof, and the opening line of the jaws is opposite to or in line with the longitudinal slit a of the roller. (See Fig. 3.) The jaws and carrier are confined within the roller-body by a cross-piece, D, at each end of the roller, and these cross-pieces D are firmly fastened to the roller ends E, and they each carry a projecting journal, F, by which to suspend the roller in :its bearings. The jawcarrier O, as to the confining cross-pieces D, is free to be moved across the roller-body. j,screwbolts, one at each end of the jaw-carrier G. These screwbolts j' pass loosely through the earpieces g of the jaw-carrier (l, and they screw into the cross-pieces I) of the roller-body, a-iid they have a collar, h, at` each side of the earpieces g.
To secure sand-paper to a roller constructed as above described, irst place one edge of the paper through the roller-slit and between the clamping-jaws 5 then wrap the paper about the roller, and similarly locate the other edge ot' the paper in the clamping-jaws. Now close the jaws tightly against the paper by properly turning their screw-bolts b, and then turn the screw-bolts fof the j aw-carrier C in the proper direction to draw the jaws inwardly from the roller-slit a. This drawing in of the jaws draws the saiid-paper in, and thus tightens it about the roller, and there it is held irmly' against escape, except it tears or breaks away under a too severe tension from such adjustment of the jaws.
To remove the saiid-paper from the rollerbody, simply loosen or open the clampingjaws.
It is not intended to limit the invention to the precise construction of parts shown, nor to the particular forni and arrangement of clanip= ing-jaws, and ol' the parts for adjusting the jaws to tighten the paper about the roller-body, as, obviously, they can be varied in many rea spects.
Having thus described my invention, what I claim, and desire to secure by Letters Patd ent, is-
l. A sand-paper roller constructed with the slit a., and with clamping-jaws B B2, that are arranged and adapted for adjustment to draw the paper aboutthe roller-body, substanA tially as herein described, and lfor the purpose specified.
2. The combination of the jaws B B2, carrier block C, and adjusting-bolts f with the crossl pieces D and roller A, having the slit a, arA ranged to operate substantially as and for the purpose speciiied.
The above specification of my invention.
