HACKER Foa CHIPPING PINE TREES.

ESPECIPICATION forming part of Letters Patent No. 325,480, dated September 1, 1885.

Application filed February l7, 18E5. (Modcl.l

To all whom it hwy concern.-

Be it known that I, RANDOLPH M. BARRON, of Castleberry, in the county of Gonecuh and State of Alabama, have invented a new and Improved Hacker for Chipping Pine Trees, of which the following is a full, clear, and exact description.

This invention relates to tools commonly known as turpentine-hackers, for chipping pine trees to cause the flow of turpentine from them.

The improved tool,in its general design and shape, is similar to other turpentinehackers in use; but it importantly differs in construction. Thus the cutting head or stock, which is of the usual loop form, standing out at right angles, or nearly so, from the shank by which the tool is secured to the wooden handle for manipulating the tool, instead of being made all in one piece, including its rounded nose end, which forms the cutting edge or portion, is of sectional construction, it being composed of a main body part and a separate bit-piece fitted to enter within the body part and held in place by adjustable means from the rear, substantially as hereinafter described. The body part of the head with its attached shank may be of malleable cast-iron; but the insertible bit is made of steel, and as it is the cutting part of the head which is most liable to wear,

the same may be readily and cheaply replaced,

when worn, by removing the old bitand inserting a new one instead of, as under the ordinary construction,in which the entire head and cutting portion is made of one piece of iron or steel, having to throw away the whole tool for a new one. Much loss of time also will be avoided by the workman carrying with him a series of bits, so that when one gets dull he can substitute another sharp one for it and sharpen the dull hits at his leisure.

The invention also includes a special construction which provides for the rapid substitution of one bit for another, and for the secure hold of thebit when in place and freedom from all objectionable obstruction, so that the inside and outside working-surfaces of the head will be smooth and clear.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a mainly sectional longitudinal view of the head and shank portion of a turpent-inehacker embodying my invention; Fig. 2, a transverse section of the same on the line a: w in Fig. 1, looking in direction of the arrows 3 y,- Fig. 3, aview in perspective of the clamp or brace used to hold the removable bit in place, and Fig. 4 a perspective ViBW of the removable bit detached.

A is the body part of the cutting or chipping head, of the usual loop form,and having, as an integral portion of it, the shank B, by which it may be attached to a wooden handle in the ordinary or any suitable manner for the purpose of manipulating the tool. Said body part, however, instead of being extended in ward to form the cutting nose or end, is made to stop square and short at its frontand sides, as at a, and said front and sides are reduced or recessed internally for about half of their thickness, terminating in a square shoulder, b. This reduced portion forms one half, 0, of a lap-joint. The other half of the joint is formed by a correspondingly outer reduced portion of the removable steel bit 0, which constitutes the cutting end of the tool. The general configuration of said bit is similar to the cutting end of other hackers, being of loop form corresponding to the loop form of the body part; but it is here a separate and distinct piece, and its reduced portion d, leaving a shoulder, e, is of like depth as the inner reduced portion, 0, of the body part, and is madeto fitsnugly within it, so that the exposed outside and inside surfaces of the bit will be flush, or thereabout, with the inside and outside surfaces of the body part, thus presenting no objectionable obstruction or break, so that the shoulders b and e, or either of them,will form asupport for the bit when in place. The bit,when inserted,is forced up and held to its place within the body part by a bent clamp or brace, D, introduced within the rear of the body part of the hea and hearing at its for ward ends against the back ends or margins of the bit. This action of the clamp is effected by a screw, E, arranged to bear on the back of the clamp and made to screw through the ICO shank B from the rear. Upon slightly turning this screw to the right or to the left, as may be, by a small wrench or otherwise, the clamp D will be forced up or relaxed to secure or release the bit, as required.

In some cases the clamp or brace might be dispensed with, and the screw E be made to act directly upon a bit having its rear end closed for the purpose. 7

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the body provided on its inner side with the shoulder 12, and the bit having its rear end inserted in said body and abuttcd against the shoulder b, of the double-armed brace inserted in the body, and having the ends of its arms bearing one on each side of the bit, and a clamping device engaging said brace, substantially as set forth.

2. In a turpentine-hacker, the combination of the main body part A of the head of the tool, having a half lap-joint portion, 0, and an attached shanlgB, the removable bit O,having a half lap-joint portion, d, the clamp orbrace D, and the bit holding and releasing screw E, essentially as shown and described.
