semi OR ABBASIVE PAPER HOLDEBi.
Specification of Letters Patent.
Patented Dec. 1, 1908.
Application filed June 10, 1907. Serial No. 378,260.
To all whom it my concern:
Be it known that I, CHARLES C. SAoLsa, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Sand or Abrasive Paper Holders, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to improvements in sand or abrasive paper holders, the main object being to provide a new and novel holder, whereby sand aper is quickly removed when worn, an re laced by a sim le and eflicient means, whic clamps the san pa er in a'rigid and'taut position upon the hol er, without the necessity of using glue or any but mechanical means.
To carry my invention into ractice, I employ a evice, which is ada ted to receive a portion of the holder, and ave the sheet of sand paper laced therein, the holder being so arranged with relation to the device, as to have the smooth surface of the paper in contact therewith. By means of a concentric means, clamping devices are so operated as to push the holder forward into closer contact with the device, while the portion of the holder is clamped tightly against the holder, stretching the sand paper and securing itupon the holder. The device is now removed from the holder, and the paper is ready for'use.
To more clearly illustrate my invention,
attention is invited to the accompanying drawings, in which 1 Figure 1 is a rear plan view of the preferred form of my sand pa er holder. Fig. 2 is a central section thereo before the sand paper has been tightened in the holder. Fig. 3 is a similar view with the paper tightened. Figs. 4 and 5 are detail views of the clamp. Fig. 6 is a detail section illustrating the angles between the disk and rim. Fig. 7 is a rear plan view of a modified form of holder. Fig. 8 is a cross section thereof with the paper in position before tightening, and Fig. 9'is a similar view with the paper taut.
Referring to the drawings :-The numeral 1 designates the holder or disk, which is secured to a lathe or other revolving medium by means of the circular lu 0r boss 2. Secured to the rear face of t e disk near the periphery thereof is a metal ring 3, which has connected thereto the sliding concentric ring 4, through the medium of the pins 5,
which are carried by the rin 4, and pass through the'curved slots 6, o the eccentric clamps 7, which are secured pivotall' to the stationary ring 3, by means of the lts or screws 8. In order to secure the sand paper upon the outer face of the holder, the eccentric surfaces 9, of the clamps 7, are thrown into engagement with the underface of the projecting rim 10, of the clamp' band or ring 11, and thus draw the clamping band, toward and over the curved periphery or sand paper and secure the turned edges thereof between the clampin band and the edge of the holder. It wil be noticed by reference to Fig. 4 that the a le a of the edge 12 is about 65 degrees, wh e the angle 6 of the clamping rim 11, of the band is degrees, thus providing a difference which allows the edges of the sand aper to be securely gripped at all points t oughout the holder.
In Figs. 7, 8 and 9, I have illustrated a modified form of holding device, which embodies a centering and securing device with the holder. This device consists of'a holding disk or plate 19, which has slidingly mounted upon its rear face near its eri hery the concentric ring 20, which is el in its relative position to the disk 19, by means of the securing devices 21. Adapted to be used in conjunction with the disk 19 to hold the sand paper upon said disk, is a clamping band 22, which has the paper grip ing inclined surface 23, which is adapte to surround the inclined peripheral edge 24: of the disk 19. In securing the sand paper to the face of the disk 19, the paper is inserted in the band rough surface down, and so that its edges project against the surface 23 thereof. The disk 19, is then inserted, the pins or studs 25, carried by the ring 20 passing through the notches 26 of the band and seating within the internal annular groove or channel 27 of the band. The ring 20, is then turned, the pins or studs 25, being thrown into engagement with the lower inclined or eccentric face of the curved plates 28, which force or move the disk 19 further within the band, so' that the crimped or turned up edges of the sand paper is gripped tightly between the surface 23 and edge 24, thus securely holding the sand paper in place. In order that the concentric rings 4 and-20, res ectively, ma be turned to fasten or un asten the c amping bands of edge 12 of the holder, and thus stretch thethe respective holders, I provide the lugs c and (Z, respectively, which are adapted to be engaged by a spanner.
What I claim, is
l. A holder for sand or abrasive paper, comprising a disk adapted to receive the paper, a band adapted to surround the disk and have the edge of the paper between it and the edge of the disk, a sliding ring carried by the disk, and wedging means 0perably connected with said ring-and adapted to be introduced between the band and disk to clamp the edge of the paper between the band and the edge of the disk.
2. A holder for sand or abrasive paper, comprising a disk adapted to receive the paper, a band adapted to surround the disk and have the edge of the paper between it and the edge of the disk, a ring mounted upon the disk so as to slide slightly concentrically, and pivoted eccentrics operated to be wedged between the band and disk as the ring is moved to draw the clamping portion of the band toward the edge of the disk. 4
3. A holder for sand or abrasive paper, comprising a disk adapted to receive the sand paper, a band adapted to surround the disk and clamp the edge of the paper between the band and rim of the disk, a ring sliding concentrically upon the disk, and a series of wedges pivoted to the disk and having handles connected to the ring, whereby as the ring is moved the wedging ends of the wedges are forced between the disk and band to cause the band to clamp the edge of the paper firmly upon the disk.
In testimony whereof I affix my signature in presence of two witnesses.
