UNITED STATES PATENT OFFICE.
EDGAR K. HAYNES, OF BOSTON, MASSACHUSETTS.
Specification forming part of Letters Patent No. 104,732, dated J une 28, 1870.
To all @hom it` may concern:
Be it known that I, EDGAR K. .HAYNEs, of
` Boston, in the county of Suffolk, State ofMassachusetts, have invented a new and Improved Needle-Sharpener 5 and I do hereby declare that the following is a full and exact description thereof, sufficient to enable those skilled in the art to make and use it, reference'being had to the accompanying drawings and letters of reference marked thereon.
It is a wellfknown fact that the largest proportion of sewingmaehine operatives are not able to sharpen their own needles properly, if at all; and the constant breakingot' the points of the needles is the cause ot' great delay and annoyance, as the largest proportion of operatives have to employ the services of others to` sharpen their needles, or throw them away.
1t is to obviate this difficulty that my inven tion relates.
The nature of myinvention consists in mak-4 ing one or more `holes in the common whetstone or emery-block or other material that may be used to whet a needle on. 1t is preferable that the holes should be larger on one end than on the other, or, in other words,
tapering, as shown at a, Fig. 3. By making the holes quite large a straight hole would Work nearly, if not qnite,as well as a tapering one, for the incline of the needle while going around the sides ot' a large hole would give the requisite amount ot' taper. l prefer the tapering hole only on account ot being smaller, therefore making the stone cheaper.
.In the accompanying drawings, Figure 1 is a perspective view of a whetstone with three holes in it ot' different sizes. Fig.2 is a plan or-top view. Fig. 3 is a vertical transverse section through the centers of the holes.
The method of operating with this needle l Sharpener is to hold a stone in one hand and the needle in the other. Place the point to be sharpened into the large end ofthe hole. Hold the needle rigidly between the lngers,and rub,
