Definitions
- Knife- Polishers have invented certain Improvements in Knife- Polishers, of which the following is a specification:
- the object of our invention is to provide a cheap, simple, convenient, and durable means for polishing knives and forks; and it consists of two. elastic adjustable cylinders coated with emeryfand connected to a base side by side, by means of screw-bolts which pass through a hole in the center of such cylinders, and are secured firmly to such base, their opposite ends being provided with thumb-nuts, which have a bearing upon collars that rest upon the ends of the cylinders. These bolts are connected together by a coiled spring near their upper ends, which yields when the back or thicker portion'of a knife is forced between the cylinders in the act of polishing the same.
- These cylinders when worn may be revolved a little by loosening the thumb-nuts, so as to bring together their surfaces at a point not worn, and may be turned in this manner at intervals as often as worn until their entire consequently bring their surfaces closer to-- gether whenever desired.

UNITED STATES PATENT OFFICE.
FRANCIS W. TARBLE, OF GHARLESTOWN, AND HORACE w. SAWYEE, OF CHELSEA, MASSACHUSETTS.
IMPROVEMENT IN KNIFE-POLlSH ERS.
Specification forming part of Letters Patent N 0. 136,188, dated February 25, 1873.
To all whom it may concern:
Beit known that we, FRANCIS W. TARBLE, of Gharlestown, in the county of Middlesex, and HORACE W. SAWYER, of Chelsea, in the county of Suffolk and State of Massachusetts,"
have invented certain Improvements in Knife- Polishers, of which the following is a specification:
The object of our invention is to provide a cheap, simple, convenient, and durable means for polishing knives and forks; and it consists of two. elastic adjustable cylinders coated with emeryfand connected to a base side by side, by means of screw-bolts which pass through a hole in the center of such cylinders, and are secured firmly to such base, their opposite ends being provided with thumb-nuts, which have a bearing upon collars that rest upon the ends of the cylinders. These bolts are connected together by a coiled spring near their upper ends, which yields when the back or thicker portion'of a knife is forced between the cylinders in the act of polishing the same.
These cylinders when worn may be revolved a little by loosening the thumb-nuts, so as to bring together their surfaces at a point not worn, and may be turned in this manner at intervals as often as worn until their entire consequently bring their surfaces closer to-- gether whenever desired.
Figure 1 is a plan view of our invention.
A is the base, which may be of cast-iron, and the screw-bolts E E connected rigidly thereto.
B B are elastic adjustable cylinders, which may be constructed of India rubber or other suitable yielding material, and their cylindrical surfaces coated with emery. O G are thumbnuts, which are made to bear upon washers H H with more or less force by means of a screwthread upon the bolts E E. These bolts are connected together near their upper ends by a coiled sprin'g, S.
By placing a table-knife between these cylwhen constructed and arranged Substantially as and for the purpose set forth.
