UNITED 'STATESl JAMES E. EMERSON, OF

TnENToN, NEw JERSEY.

IM PROVEM ENT IN CANT-HOOKS.

Specification forming part of Letters Patent No. 86,828, dated February 9, 1869.

To all whom t may concern Be it known that I, JAMES E. EMERSON, of Trenton, in the county of Mercer and State of New Jersey, have. invented certain new and useful Improvements in Cant-Hooks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a perspective view of the cant-hook as applied to a log to be turned by it. Fig. 2 represents a longitudinal section through the same.

Similar letters of reference, where they occur in the separate drawings, denote like parts in both of the gures.

y invention consists, mainly, in the manner in which the parts of the cant-hook are made, so that they will mutually support each other, and be all rmly held to the handle, without expensive fitting of the parts, and by a single key or other equivalent fastening, thus very much simplifying and cheapening the cost of the article.

My invention further consists in the use of a removable and replaceable steel point in the end of the hook, so that that part most likely to be worn away may be renewed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

The metal portions of my cant-hook may be mainly made of malleable cast-iron, which renders them very cheap and quite as durable as those made of wrought-iron, and wit-hout the necessary fitting of the latter.

rlhe serrated or rack piece a is cast with the points b, recesses c, and studs or spurs cl upon it, and is long enough to be caught by the point-band A, as well as by the clasp B, and its side, against which the handle bears, is made rounding, so as to snugly iit a rounded and tapering handle, C.

The bands A A AlI are cast with a tooth, j', upon each, corresponding to the points b on the serrated piece a, and these bands rest in the' recesses c, formed in said serrated piece.

The clasp B embraces the handle C at about its thickest part, and has4 lugs g g upon it, to which the hook D is pivoted by the pin or pivot hf.

The end of the hook D is furnished with a removable and replaceable steel point, i, which may be screwed, riveted, or keyed thereto, so that when worn or broken it may be removed, repaired, or replaced by another.

j is a key, which, in keeping the clasp and serrated piece to each other and to the handle, also unites the bands or rings to the serrated piece and to the handle, thus rendering the whole firm and substantial. k is a pike, which may be used in the end of the handle, when desired, for rafting logs, and for which canthooks are also used, and when so made the bands A A A are necessary to firmly hold the pike and prevent the handle from splitting.

The band or clasp B, hook D, and point fr', I have made of steel; but they can be made, except the point fz', of other wrought or cast metal.

The manner of putt-in g the metal pieces together and uniting them to the handle is as follows: The rings and clasp are slipped onto the serrated piece, or the latter laid into the former, and the handle is then inserted through said clasp and bands and driven 1n tight. The key j is then inserted and drlven up, and the driving of the key forces the spurs d into the wood of the handle, thus holding every part iirmly in place.

By reversing the operation, the cant-hook may be taken apart or a new handle inserted with the greatest convenience.

That the spurs d may not score or mark the handle while the latter is being driven in, the plate a at that end may be a little curved or bowed, so as to stand Loti' from the handle, and when the key is driven in, the plate and its spurs will be forced against the wood, and the spurs into it.

When dismembering the cant hook the spring of the plate, when released from the handle, will facilitate the withdrawal of the spurs from the wood.

rEhe spurs, instead of being cast on the plate a, may be separately 1n ade and inserted through holes in the plate; but I prefer eastvided with the removable point t', constructed ing them on the plate, as they cannot thus be and operating substantially as and for the 10st or misleid.

Having thus fully described my invention, what I claim therein as new, and desire to se- Witnesses: eure by Letters Patent, is-

Hook D D, herein described, when propnrposes set forth.
