TOOL FOR INSTALLING TURPENTINE-CUPS.

Specification of Letters Patent.

Patented Sept. '16, 11913.

To all whom. it may concern Be it known that l, Gannon C. Pomona, a citizen oi the United States, residing at lliloxi, in the county of llarrison and Eritate of itlississi 'ipi, have invented a new and useful tool for Installing Turpentinee ups, of which the following is a specification.

This invention relates ;enerally to turpentine tools, and particularly to a tool adapted 'toinstalling turpentine cups.

l'leretolt'ore, in order successfully to prepare the tree faces for the reception of a. cup. it has generally been necessary to employ two ax-men for the purpose, one rightand the other letbhanded, and using axes particularly adapted for their respective wi-elders. This is due to the :t'act that ambidextrous ax-men are scarce, and that the average axanan has trained himself to work trom one side only. As is well known, right-handed axunen predominate in munbers, and so it frequently happens that an operator or contractor cannot supply himself with a leitt-lmnded one, the result being that he is hampered in his work and loses much valuable time for which he has to pay for the services of unskilled and thus unsatistactory labor.

it is the object of the present invention, in a novel and practical manner, to obviate the above objections by providing a tool that shall be adapted to be used by either a right. or a left-handed arc-man, the construction oil which will materially :t'acilitate the operation and lessen the labor of forming the tree faces, and which shall reduce to the minimum the danger of cutting too deep and thus injuring the trees.

Nith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel COl'lStl'llCtlOn and combination of parts of a turpentine tool, as will be hereinafter fully described and claimed.

In the accompanying drawing forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a View in perspective of a tool constructed in accordance with the present invent-ion. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional View on the line 83 of Fig. 2. Fig. 4: is a rear elevation of the tool.

The tool comprises a cutting head designated generally .t, a shank Q, and a neck connecting the head and the shank. As shown in Fig. 13, the cutter head comprises a straight 'lront cutting edge 4- and a pair at curved lateral cutting edges 5, that merge into the neck 3, the latter coinstituting a continuation ol the shank .2, which is disposed in approximate parallelism with the front edge -t-. The cutter head is av hollow structure of an approximately irregular elliptical torn), providing thereby ample space for the escape 01 chips in the use oi the tool, whereby any loss of time which would result from clogging is prevented.

()ne ol the essential 'teaturcs of the invention is the manner of disposing the side cutting edges 5 relative to the "front. cutting edge, the former edges, as shown in Fig. 2, being disposed approximately at an angle of 14) degrees to the trout cutting edge (3, so that a clean initial cut, known as the lirst streak may be formed, which will a .:curately define the limit of the lat eral cut, in one direction oil the lace.

The cutting edges 5, as shown in Fig. l, terminate some distance short of the neck, thus further to permit the escape of chips.

The cutter head as a whole is combined with a handle 7 having adjacent one end an all-through slot; 8 in which the neck tits, the shank being disposed within a longitudinal channel 9 arranged in the handle on the side opposite that through which the neck is inserted, the inner wall 10 ot' the channel being shaped in such manner as to conform to the adjacent; portion of the shank. By this arrangenlent it will be seen that the force of the impact resulting from the use 01' the tool will have a teiulency always to seat the shank in the channel, so that accidental disconnection of the parts in use will positively be precluded.

As will be obvious, in order to secure the above results, the cutter head as a whole should be comparatively thin, and to impart the desired weight to the tool to enable it to deliver etleetive blows, the handle has combined with it at the end opposite that carrying the head, a spherical weight 11, which will in effect secure the same -function as if the head were made of thick metal.

In the use of the tool, the ax-man cuts his first streak, say on the left hand side Off the center line of the two faces, this cut resembling a half-auger hole, and the straight cutting edge of the tool is then brought into play and will remove the bark up to the point which will be considered the median line of the two faces, and the operation is then repeated on the right hand side, and when the two faces are cleared of bark, the two incisions to receive the turpentine gut-- ter are made with the straight edge of the cutter head in the same manner as that ac- Owing to the shape of the tool, it will beadapted to be used as a scraper, thus materially broadening the scope of its utility.

It will be noted that the side portions of the head converge backwardly toward the shank and they thus constitute means for abutting against one side of the handle while the shank is engaging the opposed side thereof. Thus the head of the tool is prevented from sliding toward or away fro-m the handle. Furthermore, as the inclined lower edges of the head converge upwardly toward the shank, it will be seen that they permit the head to be tilted downwardly toward the handle, thus to permit withdrawal of the shank from the handle.

I claim:

The combination with a handle, of a cut ting element comprising, in a one piece structure, a shank, a cutting head thereon having a straight front face and side portions converging from the front face to the shank, said straight front face having a straight cutting edge and the side portions being formed with inclined cutting edges converging toward the shank and disposed in a plane that approximates an angle of 45 degrees to the straight front face of the cutting head, the cutting head and shank being connected by a straight neck disposed at right angles to the shank and adapted to be removably seated in the handle, said shank constituting means for engaging one side of the handle and said diverging side portions constituting abutments for the other side of the handle, to hold the head against sliding movement toward or away from the handle, the inclined lower edges of the head constituting means for permitting clownward tilting of the head relative to the handle and the withdrawal of the shank from the handle.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
