FULLER STOCK Filed May 26, 1950 i 1 J.- FZZ 1| 1i (9/ ,I "J J J I -10 IN VEN TOR A TTORNEY Patented Feb. 15, 1932 ATNT WILLIAM I1. SMITH, OF D6NALSQNVILLE, GEORGIA FULLER Application filed May 2e, I

The object of this inventionv is to furnish a durable and eflicient puller stock, same being an implement used in the process of securing gum from turpentine trees by streaking the trees.

The device is particularly useful when after repeated streakings the turpentine face is located too high in the tree to work with a hack; this period being reached after the face of the tree has been worked with the hack for several years.

Heretofore, puller stocks have been made of wood, with an opening therein to receive the puller, but under strains of use .the stock becomes badly worn and must be discarded.

The invention consists of a metal stock, recessed to receive the puller or knife, and socketed to receive a wooden or other attached 0 handle, as I will proceed now to explain more fully and finally claim.

In the accompanying drawings illustrating the invention in the several figures of which like parts are similarly designated, Figure 1 is a perspective view showing part of the handle in dotted lines. Fig. 2 is a rear view. Fig. 3 is a longitudinal section showing the puller in position in dotted lines.

The stock preferably is a one-piece casting of aluminum, because of its lightness and strength, although other metals may be used. The lower part of the stock is made tubular, as at 1, to receive handle 2, which may be inserted therein and secured by screws or other fastenings engaged therewith through the holes 3 or otherwise. The upper portion of the stock is provided with the head 4:, having the fore-and-aft slot 5, and the substantially straight face 6. The upper portion of the slot is curved at 7, and substantially straight as at 8, with the rearwardly extending shelf 9, and the longitudinally extending groove 10.

The puller or tool has the cutting blade 11, from the rear of which extends the shank 12, which fits in the slot 5, and the downturned portion 13, which lies in the groove 10. As indicated in Fig. 1, the cutting element stands laterally across the face of the stock, and its lower portion or cutting edge proper is shaped so as to streak the tree most STOCK 1930.

efiiciently to produce the flow of'gum. The

portions

12 and 13 are at substantial right angles one to the other, and the space between the curved portion 7 and the straight portion 8 and the back of the shelf 9 is sufficient to permit the puller to be inserted in the stock readily and to be held therein without danger of accidental dislocation.

The bottom of the groove is provided with a shoulder 14 which serves as a stop for the lower end of the portion 13 of the puller.

In operation the back of the blade 11 comes into contactwith the straight face 6 of the head and this face thus forms an abutment or stop for the puller. r

As will be observed,'the puller blade is self-contained within the stock and so positioned and heldwithout the use of extraneous fastenings. Obviously the puller blade may i be readily attached and may be equally read- '70 ily detached or removed for sharpening or replacement purposes. The relation of the puller blade to the stock at the head of the stock is such that there is an open unobstructed passage for the chips or shavings from the blade so that they may curl. over the end of the stock and invariably fall to the ground without contact with the gum cups. While it is preferred to make the stock with a socket to receive an attached handle, it is within the scope of my invention to make the handle in one piece with the stock.

By the construction described a strong and durable implement is produced.

Variations in the details of construction are permissible within the principle of the invention and the scope of the claims following.

WhatI claim is:

1. A puller stock, having a handle-receiving socketat one end, and a head at its other end slotted fore-and'-aft, and havingthe top of the 'slot curved andthe bottom of the slot straight and the face of the slot likewise straight, said slot'openinginto a longitudinally arranged groove at the back of the stock, the slot and groove adapted .to receive a puller.

2. A pull-er stock, having a head at one a end and slotted fore-and-aft, the top of the slot next to the top of the head being curved fore-and-a-ft and the bottom of the slot being straight, and the face of the stock adjacent to the slot being straight, said slot opening into a longitudinally arranged groove at the back of the stock, combined with a puller blade having a cutting edge extending transversely of the stock, the back of the blade being flat so as to lie flat against the straight face of the stock, said blade havinga shank and a depending portion by Which said blade is entered and positioned Within said slotand its adjacent groove, the puller blade being self contained.

In testimony whereof I have hereunto set my hand this 23rd day of May A. D. 1930.
