FLEXIBLE A'BRASIVE OR POLISHING DISK. I,
SPECIFICATION forming part of Letters Patent No. 336,695, dated February 23, 1886.
3 Application filcl May 2|, 1855. Serial N0.1G6,305. (No mam To all whom it may concern.-
Be it known that I, JOSEPH W. BYERS, of Charleston, in the county of Coles and State of Illinois, have invented a new and Improved Flexible Abrasive or Polishing Disk, of which the following is a full, clear, and exact description.
This invention is more especially designed for use by dentists on artificial plates or plates of false teeth, and as a device essentially differs from other flexible and abrading devices for operation on natural teeth.
The invention consists in adisk havinga circularbody of flexible material and circular outside layers of flexible material having an abrasive substance on and over their outer faces on opposite sides of thebody to which they are cemented, and arranged to project beyond the perimeter of said body. This flexible, pliable, and elastic disk, when used for the purpose for which it is especially designed-namely. for dressing and finishing rubber plates and artificial dentures-is carried on the mandrel of a lathe such as used by dentists in connecdisk embodying my invention.
tion with their laboratory-work.
Reference is to be had to the accompanying drawings, forming part of this specification, in
which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 represents a partly broken side or face view of a flexible abrading and polishing Fig. 2 is a transverse section of the same as applied to the mandrel of the lathe. Fig. 3 is a transverse section, upon a larger scale, of the disk in part, ,with itsabrading-layers having their projecting marginal portions bent over the perimeter of the body of the disk to form a cutting-edge; and Fig. 4, a view in perspective of the disk applied to the lathe-mandrel a d forced down over the head of said mandrel, which is the position the disk would assume when it is used to work on the palatine surface.
. The following brief statement will serve to better explain the objects and advantages of my invention: Dentists have heretofore, after taking the plate out of the vulcanizer, spent much time and labor in removing adherent particles and surplus material, firstusing a file and vulcanite burr and then a steel scraper,
piece of glass, and other implements of similar character, followed up by sand and emery paper, held either by a carrier or between the fingers, and afterward polishing with pumieestone and the brush-wheel. This not only necessarily consumes much time and laborybut often subjects the plate to breakage from the pressure brought to bear upon it in thus cutting and finishing it. My improved device is designed to completely supersede the file, vul-- canite burr, scraper, glass, and other clumsy expedients and implements heretofore regarded as indispensable to the dentist in connection with the finishing of artificial plates, and it serves to render the work both easier and pleasanter, avoiding injury to the fingers and breakage of the work, and producing betterfinished work'in less time than was required under the old method. D
The flexible disk A represented in the drawings has a flat circular body, b, made of cloth,
- rubber, leather, or other flexible material that will remain pliable (in ring the process of manufacture. This circular body b is entirely cov- 7 5 ered on its opposite faces with circular abrading or cutting layers 0 c of flexible material, such as sandpaper or other abrasive flexible materia'l having the necessary dressing, grinding, and polishing qualities. These outside abrasive layers a c are of larger diameter than the body I) of the disk, so as to extend beyond the perimeter of said body, thus forming peripheral flanges, which are bent down over the'outer margin n abrading-edge of the disk. ,Said outside flexible abrasive layers, 0 c,'are secured by glue or other cement to the opposite faces of the flexible body I) of the disk. This disk A is provided with a hole, (I, in its center, to admit of its he go ing passed onto the shaft or mandrel B of the lathe, and to which it may be secured by a screw, e, or otherwise. The entire surfaces of both of its sides or faces, as well as its outer edge or perimeter, are to bensed in the work. 5 When rapidly rotated in the lathe in dressing the rim and sides of the plate under manipulation, said disk becomes worn and softened,
and is then readily forced down into the more inaccessible places-such as the palatine sur- 100 face, commonly known as the roof, or other concave surfaces-and in this manner,the disk of the body I), and form the I being bent over, as in Fig. 4, the cutting or abrading-surface of the disk lying near to and at the head of the mandrel is utilized. v
The size of the disk may be varied. From one and one-halfinch to two and one-half inches in diameter will generally suflice, however for'artificial plate-Work.
By the disk having the abrading material applied over both of its sides or faces and overlappingtheperi meter of its body on both sides, it may be reversed on the mandrel for opera tion from either side, and presents double grinding-faces'anda grinding-edge, which will add materially to its usefulness and durability. Having thus described my invention, what I claim as new, and'desire to secure by Letters Patent, is-
1. Thewithin-descr'ibed flexible abrading or forth.
polishing disk, composed of a circular body of flexible material andcircular layers of flexible abradiug material secured to audover said body on its opposite sides or faces, and arranged to extend beyond the outer margin or perimeter of the body, substantially as specified.
2. The combination, with the mandrel B, of the flexible abrading-disk A, having aflexible circular body, b, and flexible layers 0 c of abradiug material on and over its opposite sides or faces and of greater diameter than the body, essentially as and for the purposes herein set r JOSEPH W, BYERs, \Vitnesses:
