UNITED STATES latented July 7, 1903 PATENT OFFICE.
POLISHING CONE AND WHEEL.
SPECIFICATION forming part of Letters Patent No. 732,949, dated July 7, 1903.
Original application filed May 1, 1902, Serial Nor 106,572; Divided and this application filed October 6, 1902. Serial No. 126,178. (No model.)
To all whom it may concern..-
Be it known that I, LEONARD G. KOENIG, a citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements inPolishing Cones and Wheels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to polishing cones or Wheels primarily intended for use by jewelers and dentists, being a division'of an applica-. tion filed byme Mayl, 1902, Serial No.105,572
and the object of the invention is to treat the wheel or cone so as to enhance its usefulness as Wellas prolong its life.
Cones or wheels used on lathes for polishing rubber plates, crown bridge-work, and jewelry are made in part or wholly of felt. In
accordance with my invention I apply to the felt a solution of shellacsay, for instance, a twenty-five per cent; alcoholic solution-while theshellac is in an unheated state and allow the shellac to be absorbed by the cone or wheel and to become dry, thus hardening the felt and producing a durable and highly efficient polishing Wheel or cone which will not soften by the continual use of water in polishing. After the felt wheels'or cones have thus been hardened in shellac and dried they are dipped in a solution of heated glue to render them somewhat less brittle, and by using a glue solution of appropriate strength and heat I 3 5 am enabled to thus temper the felt wheels or cones, so that the same are of any required degree of brittleness.
In the accompanying drawings, Figure 1 is a view of a dental polishing-cone, and Fig. 4d 2 is a view of a dental polishing-wheel, treated in the manner above set forth.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- 4 5 1. A polishing or abrading'device of the class described made of felt, saturated with a solution of shellac which is allowed to dry and harden, and subsequently saturated with a solution of heated glue, substantially as de- 50 scribed.
2. vThe herein-described process of hardem ing a felt polishing or abrading device, con sisting in saturating the same with a solution of shellac, drying the same to fix the shellac 55 therein, and subsequently applying a solution of heated glue to the said device and allowing the same to dry.
I11 testimony whereof I have hereunto set my hand in presence of two subscribing wit- 6o nesses.
LEONARD G. KOENIG.
