IVILLIAM (l. KELLY, OF LOUISVILLE, KENTUCKY, ASSIGNOR TO TIIE KELLY AXE MANUFACTURING COMPANY, OF SAllilE PLACE.

DIE FOR MAKING AXPOL.I.S.

SPECIFICATION forming part of Letters Patent No. 397,369, dated February 5, 1889.

Application tiled June 27, 1888. Serial No. 278,375. (No model.)

To all whom it may conoci-7L:

Be it known that I, WILLIAM C. KELLY, a citizen of the United States, residing at Louisville, Jefferson county, Kentucky, have in- 5 Vented new and useful Improvements in Dies for Making Ax-Polls, of which the following is a specification.

This invention relates to certain new and useful improvements in dies for the manufac- Io ture of axpolls; and it consists, substantially, in the construction thereof, as will hereinafter be Inore particularly described and claimed.

The object of the invention is to construct a die for producing an aX-poll by which to I5 make an ax such as is described and claimed in Letters Patent No. 372,275, granted to me on the 29th day of September, 1885, the novel feature of which aX consists in making the blade of a practically uniform thickness and 2o tapering from a point at or near its center toward the edges, the lines of taper diverging from said point toward the points of intersection of the back and front edges of theblade with the cutting-edge.

I have iiled of even date herewith an application for patent for the poll produced by the dies of the present invention; hence no claim for the poll is herein made, although the same is illustrated for the purpose of completeness 3o and understanding.

Referring to the accompanying' drawings, Figure l represents an isometrical perspective Aview of one of the dies employed. Fig. 2 represents t-he two dies, together with the poll 3 5 between them, each beingin longitudinal section. poll formed by the dies.

Reference being had to the drawings b ythe letters marked thereon, A represents the die,

4o the same being hollowed out or recessed between the points marked a and a', and but for the presence of eorrespondingly-shaped and oppositely-arranged projections b b .the bottom or base of such recess or cavity would 45 present a gradually curved or dished surface Fig. 3 is a view in perspective ot' the,

between such points a, and a', the said curvature being designed to give general shape to the poll. In line with the eye of the poll I also make or form in the top of the die the cavities o c for the mandrel, by which the poll 5o is manipulated between the dies bythe workman.

The projections l) b are each the counterpart of the other in shape, and are formed at opposite sides of the cavity or recess, prefer 55 ably, though not essentially, with a dividingspace, d. The one face, e, of these] n'ojectio11s is beveled inward slightly, and is approximately straight vertically; or, instead of being slightly beveled, the same may be straight 6o or in conformity to the curve of the eye of the .I ax when iinished, while the lines bounding their upper faces, j', are curved, as shown, and unite or intersect with each other at curvilineal angles. These projections are for pro- 6 5 ducing in the ax-poll correspondingly-shaped depressions or cavities such as are indicated by the letters g g-while, due to the shape of the cavity or recess of the dies, the main body of the poll receives its general contour or 7o shape.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent,

l. A die for making ari-polls, having in its 75 face a cavity or recess and formed with the lprejections l; Z1, substantially as described.

2. A die for making axfpolls, having in its face the cavity slightly curved between the points (L o. and formed with the projections 8o b l), the boui'nlary lines of which intersect each other in cu1 vilineal angles, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing wit- 85 nesses.
