AX-POLL- Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed March 13, 1905. Serial No. 249,828.

Be it known that 1, CHARLES A. Bnx'rox, a citizen of the United States of America, residing at Eaton Rapids, in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Ax-Polls, of which the following is a specification.

This invention relates to ax-polls, and more especially to that class made from blanks.

The object of this invention is to produce an axpoll with the, grain of the iron or steel running both ways, making it strong and under all tests conducted unbreakable.

A further object of this invention is to produce a poll that will be simple in construction and economical to manufacture.

\Yith the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to behereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying d rawings, forming part ofthis specification, wherein like characters denote corresponding parts in the several views,'in which Figure 1 is a view in side elevation of a blank, showing the first step in the process. Fig. 2 is a similar view showing the second step. Fig. l) is a similar view showing the third step. Fig. at is a similar view showing a modified form of poll.

in the drawings, (1 indicates a suitable blank, of iron or steel, preferably steel, which has its grain running longitudinallyof its length. The ends I of the blank are beveled. The end portions (2 of the blank are turned back upon the said blank and contact therewith, the bevel of the ends inclining toward the blank. This constitutes the first step of the process, as plainly shown in Fig. 1. The second step of the process consists in bending the blank centrally, as at upon itself into an approxii'natc U shape, as illustrated in Fig. 2, after which the fillingblock is further pressed, bringing the turned-back portions into contact one with the other, as shown in Fig. 3. A small filling-block of bar metal (1, preferably the same as the blank, convex at one end and concaved at the opposite end f, is placed within the curved or bent portion, with the end (3 against the bend 1/, the whole being then pressed into shape and welded together, making a complete eye through the poll.

It is to be noticed that the diameter of the filling-block is in excess of the thickness of the contacting portions of the blank; but it is to be understood that the diameter of the bar may be varied at will to meet particular requirements.

In Fig. 4 the poll is made the same as the aforesaid, except the bar 1. In this process a longer filling-block or bar 1, of metal, having its ends 3 beveled, is employed. The filling-block is bent centrally upon itself and placed within the bent portions of the blank 4:, with the curve5of thelilling-block 1 against thccurve 6 of the blank. The blank and [illing-block are then pressed into shape and welded together as in the first process.

Having fully described my invention, what i claim as new, and desire to secure by Letters Patent, is

1. A poll consisting of a single blank, bent centrally upon itself and a filler-block interposed between the bcnt portions of the blank at the curve thereof, whereby an eye is formed.

2. A poll consisting of a single blank having its ends turned back, said blank being bent centrally on itself with the turned-back portions in contact, one with the other, and a block interposed between the bent portionsof the blank at the curve thereof, whereby an eye is formed.

3. A poll consisting of a single blank bent centrally upon itself, and a block interposed between the bent pm'tions of the blank at the curve thereof, said block comprising a bar turned back centrally of itself.

In testimony whereof I aflix my signature,in the presence of two witnesses, this 10th day of March, 1905.
