as will enable others skilled in the art to which it appertains to make and use the same.

Peaveys are tools which are used by lumbermen for handling logs, and the men using them are required to make many thousands of motions during a day and to handle the implement quickly, in consequence of which the tool should not be heavy and cumbersome in the hands of the operator, while at the same time the tool should have the strength necessary to stand the strain in manipulating the logs. I aim to lighten the weight of the tool and increase the strength, durability, and Wear and to fashion the wooden handle and construct the metallic pick-ferrule so as to distribute the relative thicknesses of the wood and metal, so as to reduce the size and heft of the wooden part of an ordinary peavey and increase the strength of theferrule at the point where the implement is exposed to the greatest strain and wear.

The present improvement relates more especially to that class of peaveys in which the pick is united or Welded to the small end of a metallic ferrule to render the ferrule and pick fast and solid, and to this ferrule is provided a cant-dog. The ferrule of my improved implement may also be utilized in the manufacture of cant-dogs, which are distinguished from the implements known to lumbermen by the technical name of peaveys, owing to the fact that in a cant-dog the pick is omitted, While such pick is always present in a peavey. In implements of this class it is desirable not only to'reduce the size and weight of the tool and increase the strength of the juncture of the pick with the ferrule, but also to secure the ferrule firmly and solidly to the-end of the wooden handle. 4To

. this end the handle and ferrule have ordiare bent and embedded firmly in the handle, to the end that the ferrule or band may be' secured more firmly in place, such clenchable lips tending to counteract anyliability of the wedge-joined handle and ferrule from separating.

To enable others to understand the invention, it is represented in the accompanying drawings, forming a part hereof, in which- Figure 1 is a side elevation of a pcavey embodying the present improvements. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a detail perspective view of a ferrule or band blank prepared in accordance with my invention. Fig. 4 is'a longitudinal section of the ferrule or band when bent to proper form and prepared from a blank such as shown by Fig. 3. Fig. 5 is a detailview of the handle.

Like numerals indicate like parts in each figure of the drawings.

As is usual in the art, the peavey consists of a metallic band or ferrule 10, the pick 11, the handle 12, and the dog 13, which is pivoted at 14 to the band.

The leading feature of the present improvement resides in the construction ofthe ferrule or band, and while the ferrule of my invention is a peculiar mechanical structure, which distinguishes i't from all prior devices known to me and makes it capable of being cast in a single piece from a suitable metal, such as malleable iron, yet I prefer to roll the ferrule in blank form in a single piece of sheet metal by rolls or dies for taper-rolling of the type disclosed by my prior patents and applications for patents.

A rolled blank suitable for the manufacture of one style or typeof band or ferrule 10 is represented by Fig. 3 of the drawings, in which the numeral l5 designates a sheetsteel rolled blank. This blank is rolled to a proper form or condition, and it is of a size proper to be bent into a conicocylindrical form to fit and wedge itself to a reduced tapered end of the handle.

The prime feature of my invention consists in giving a taper to the rolled blank, so that the metal will diminish in thickness toward both ends of the blank from the lower small end of the conicocylindrical socket vformed for the handle 12 by rolling the blank upon itself about a longitudinal axis, and

ICO

this form of the blank secures an increase in the thickness of the metal, and consequently an increase in strength and durability at that part of the band where the pick and handle meet and where the greatest strain is imposed on the implement in the practical service thereof. As shown by Fig. 3, the blank has a longitudinal taper toward both ends from an intermediate transverse line, so that at the line a; it is very much thicker than at the line z, and the blank is thinnest at the line o. The longitudinal sides or edges of the blank are also oppositely beveled, so that when the blank is bent to form a socket such edges will form a close joint and can be welded together to form a socket having unbroken Walls, which are of equal thickness at all points in each of any transverse planes, but vary in thickness on longitudinal lines-that is, as pointed out above, from the line m the blank is decreased in thickness toward the edge of the blank, and thus the blank has a double taper in opposite directions from the line 0c. After having prepared the blank by rolling it to the contour described it is bent around a proper form or by any approved means to the conicocylindrical contour represented by Fig. 4, and this results in the production of a ferrule having the thickest part of the metalat the point 1G, due to the fact that the metal at the line in the blank is thicker than at any other point. The ferrule or band produced by such a blank has an elongated tapered socket 18 and a short tapered socket 19, and these two sockets taper in opposite directions from the place where the greatest thickness exists in the metal at 16 of the band or ferrule.

The pick 11 is a solid single piece of metal which is rolled to the proper form or prepared by dies in a manner suitable for union with the ferrule or band. This pick has a rounded tapered short stem 20, of a length approximately equal to the short socket 19 of the band, and the exposed or working part of said pick has the facets 21, which lie at angles to each other and are inclined to give the working end of the pick a wedge-shaped appearance. Y The short stem 20 of the pick corresponds in contour and dimensions to the internal form of the short socket 19 in the band or ferrule, and this pick and the band are united solidly and iirmly together by welding the short socketed portion 19 of the band around the stern 20 of the pick.

By reference to Figs. 3 and 4 of the drawings it will be seen that a socket is formed in the upper or inner end of the pick 11 and that the lower end of the stail is of such form and size as to iit snugly in such socket.

By reference to Figs. 1 and 4 of the drawings it will be seen that the pick 11 is of such size and form as to be a direct continuation of the ferrule or band-that is, itis to be noticed that I avoid entirely the forming of any ridge or flange about the pick at the lower end of the ferrule. The presence of such a flange or annular projection has been one of the great objections to the forms of peaveys which have heretofore been employed. The presence of such a ange interferes to a great extent with the proper handling of the implement. l

Another feature of my invention consists in producing the upper large end of the ferrule with clenchable prongs 22. These prongs are an integral part of the rolled blank by the formation of a scallop or corrugation at the thin edge of the blank, and as these lips are formed on the thin edge of a steel blank they are adapted to be bent or hammered, so as to embed themselves rmly in the wooden handle 12.

The advantages of this construction will be readily appreciated by those familiar with the uses of such an implement as that herein presented and with the disadvantages incident to having the upper end of the-socket or ferrule form a ring-like projection about the staff orhandle-that is, with those constructions heretofore proposed and in use with which I am acquainted, in which the ferrule or band was formed by bending up a blank of uniform gage, so that the walls of the socket were necessarily of the same thickness at all points longitudinally, the upper end of such socket projected beyond the handle at all points a distance equal to the thickness of its Walls. This offset or projection has been frequently the cause of accidents. For instance, when the pick has been inserted between two logs and it is necessary to quickly withdraw the same the square shoulder at the upper end of the ferrule strikes against a knot or the surface of a log in its path and often causes the operator to lose his slight foothold and be thrown into dangerous positions.

By making, as I do, the upper end of the ferrule or band the thinnest of all its portions and by embedding such ends in the wood of the handle I avoid entirely any abrupt flange or offset at the upper end of the band, and instead the said end of t he ferrule and stai gradually meet, and there is no obstruction whatever presented at that point. This handle or staff is of any suitable wood, and the end of the staff to be joined to the band or ferrule is turned down in a lathe to a tapered form circular in cross-section in order to produce a tenon 23. This tenon is adapted to wedge itself firmly in place in the elongated tapered socket 18 of the band or ferrule, so as to abut against the solid thickened portion 16 of the band to hold the parts firmly against displacement in one direction, and the upper scalloped or lipped edge of the band or ferrule extends or laps over that part of the staff which is between the tapered tenon 23 and the handle portion of the staff, so that the clenchable lips may be bent into engagement with or embedded in the staff to hold the ferrule firmly in place and counteract any tendency of the ferrule and sta to separate in a IOO Ipo

direction opposite to the line of wedging action between the ferrule and the staff-tenon, whereby the staff and ferrule are joined firmly together against separation in any direction.

The cant-dog 13 is connected to the Vband or ferrule at the upper larger end thereof by the pivotal bolt 14. This eye-formed heel of the cant-dog is Iitted between lugs 24, provided on the lower face of the enlarged end of the ferrule, and the pivotal bolt is slipped or passed through coincident openings in said lugs and the eye of the dog-heel, a suitable nut being screwed on the .end of said bolt. The lugs may be in separate pieces from the ferrule and be welded rmly thereto; but I prefer to make lugs integral with the rolled blank, as shown by Fig. 3. These lugs 24 are separated from the side edges of the blank at the thin upper edge of the same by the notches or incisions 25, and 4in the operation of bending the blank to the conicocylindrical form the lugs are bent on the score-lines 26 to occupy radial positions to the longitudinal axis of the ferrule and to be parallel to each other, so as to properly receive the heel of the cantdog.

'Ihe pick and the cant-dog may be of any style or contour preferred by the skilled constructor or the workman.

Theimproved construction of the peavey secures an increased thickness of metal and consequent strength and durability at the point where the end of the staff and the pick-stem meet or join, and this is of vital importance in an implement of this class, because `it is at this point that the implement is subjected to the greatest strain and wear in its practical service or use. The taper given to the conicocylindrical portion of the band which receives the staff and the increased strength afforded by the thickened lower end of the ferrule or band enables me to manufacture pevies having a smaller staff, and consequently of less heft than ordinaryimplements now on the market. The size of the implement may thus be decreased; but the improved const-ruction results in a stronger and more durable implement, which can be handled quickly and more expertly by the operatives.

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

l. In a peavey orcant-hook,the combination of a staff or handle, andl a ferrule or band having a socket adapted to receive the lower end of said staff, the walls of said socket decreasing in thickness from their lower to their upper end and the reduced upper end being embedded in the staff, whereby the presence of an abrupt offset or projection about the staff at the upper end of the ferrule is avoided, substantially as set forth.

2. Inapeavey or cant-hook,the combination of a staff or handle, and a ferrule or band formed from a rolled blank which is tapered longitudinally and has its side edges oppositely beveled, and is turned upon itself about a longitudinal axis to form a socket to receive the lower end of the staff or handle and having walls which decrease in thickness from their lower to their upper end, the upper reduced end of said ferrule having a series of retaining-tongues embedded in the staff'or handle so that the upper end of said ferrule is iiush with the stad, substantially as set forth.

3. In a peavey, the combination with a staff or handle, a ferrule or band formed from^a rolled blank which tapers toward its ends in opposite directions from an intermediate transverse line, whereby when the blank is rolled upon itself about a longitudinal axis there will be formed two sockets which increase in width and whose walls decrease in thickness from their adjacent ends toward opposite ends of the ferrule, one of said sockets receiving the lower end of the handle and having its upper reduced end embedded in the body of said handle, and a pick secured in the other socket in the ferrule, substantially as set forth.

4. In a peavey, the combination of a staff, a ferrule or band having at one end a socket to receive the lower end of the stad and at its opposite end a socketA for a pick, and a pick secured in the last said socket and provided at its inner or upper end with a socket or seat for the lower end of the stad, substantially as set forth.

5. In a peavey, a rolled ferrule or band blank which has a long longitudinal taper in one direction and a short taper in the opposite direction, said blank bent into conicocylindrical form to produce two tapered sockets with the greatest thickness of metal at the line between the two sockets, substantially as set forth.

6. The herein-described ferrule or band, for a peavey, formed from a blank rolled to taper toward both ends from an intermediate transverse line, the side edges of said blank being oppositely beveled, whereby when the blank is rolled about a longitudinal axis and said beveled edges are secured together two oppositelyflaring conicocylindrical sockets are IOO IIO

formed, the walls of which decrease in thickness, longitudinally, from their inner adjacent ends toward the open ends and the greatest thickness of metal is provided between said sockets, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
