Application filed March 12, 1908. Serial No. 420,726.

T all whom it may concern:

Be it known that I, NATHANIEL B. STONE, a citizen of the United States, residing at Outlook, 11 the county of Yakima and State of \Vashington, have invented a new and useful Turpentine-ITack, of which the following is a specification.

This invention relates more particularly to that type of implement employed in scoring trees for securing the sap and gum therefrom.

One of the primary objects of the present invention is to provide an implement in which the depth of the score or out can be accurately gaged, said implement furthermore being so constructed that there is suiiicicnt clearance for the free passage of the chips and crumbs of loose bark therethrough, thereby avoiding all liability of the same becoming choked and inoperative.

A further object is to provide a structure that will permit the hand of the operator to be placed in the same position with respect to the cutting blade that it is now placed with the ordinary tool, thus permitting the same character of working stroke.

Still another object is to provide a tool from which the blade can be readily removed for the purpose of sharpening or in order that it may be sup alanted by a new one.

The preferred form of construction is illustrated in the accompanying drawings, wherein Figure 1 is a perspective View of the hack.

- Fig. 2 is a sectional view through the head of the same. Fig. 3 is a detail sectional view on the line 33 of Fig. 2. Fig. e is a sectional view on the line a 4 of Fig. 2. Fig. 5 is a rear elevation of the head. Fig. is a detail perspective view of the cutting blade. Fig. 7 is an end view of the same. Fig. 8 is a detail perspective view of the head with the associated parts detached. Figs. 9, 10 and 11 are perspective views respectively of one of the cover leaves, the cap spring and the jaw plate. Fig. 12 is a detail sectional view on the line 1212 of Fig. Fig. 13 is a detail perspective view of the slide block.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a handle 13 is employed, comprising a center plate 141, to the opposite sides of which are fastened wooden grip sections 15/ One end of the plate 1% carries a suitable weight 16, while the other end is provided with a transverse head 17 disposed substantially at right angles to the handle and having outstanding flanges 18 along its outer margins, said flanges projecting from opposite sides and forming in efiect a jaw. The flanges furthermore have ribs 19 on their inner faces, said ribs producing seats 20. A clamping plate or jaw 21 is associated with the inner side of the projecting portion of the head 17, and its opposite side margins project beyond the opposite sides of said head. These margins are also provided with suitable ribs 22 in opposing relation to the ribs 19. The plate has a stem 23 that extends into an opening 24 formed in the head, and a clamping nut 25, located on the opposite side of said head, is provided with a boss 26 journaled in the opening and having a threaded socket that receives the stem. It will thus be evident that by rotating the nut in one direction, the clamping plate will be carried toward the head. The said head furthermore has an elongated socket 27 disposed transversely of the handle, and located therein, is a reciprocatory slide block 28 having serrated ends. An adjusting screw 29 having a projecting head 30 is journaled in a retaining block 31, screwed into the head 17, and the screw 29 has a threaded engagement with the block 28. A substantially U-shaped cutting blade 32 is employed that is provided with terminal shanks 83, said shanks bearing against opposite sides of the head 17 and extending between the flanges 18 and the jaw plate. The said shanks are of sufficient width so that when the jaw plate is drawn toward the head, said shanks will be clamped between the flanges of the head and the flanges oi the plate. The free ends of the shanks have slots 3st, and said ends overlie the slide block 28. Cover leaves or plates 39 are arranged over said ends of the shanks, and screws 40, passing through the cover leaves, pass through the slots 3 1 and are threaded into the opposite sides of the block. The rear ends of the leaves 39 are doubled and bent outwardly, as illustrated at 1-1, and a cap 42, held in place by the block 31, is provided with spring terminals 43 that bear against said outturned ends 31. lVith this arrangement therefore, it will be evident that if the screws l0 are loosened, the leaves will be swung outwardly, thus producing an open throat into and out of which the shanks 33 of the cutting blade 32 can be readily slipped when the clamping jaws are loosened.

It will be noted that the body of the blade, designated't4, projects in advance of the shanks 33, and terminates in a U-shaped cutting edge 45. Moreover it will be ob served that the opposite sides of the body and of the shanks flare rearwardly and outwardly so that the area at the rear end of the blade is considerably greater than that at the cutting edge. Projecting from the free end of the head 17 at one side of the handle, longitudinally of said handle and in spaced relation thereto, is a stem t6, the free end of the stem being at a slightly greater distance from the handle than the secured end. This stem, as will be clear, particularly by reference to Fig. 2, extends from a point within the cutting blade 32 to a point considerably in advance of the cutting edge, and its rear portion is preferably cut away, as shown at at in order to leave the space within the blade and particularly within the rear portion thereof completely unobstructed. For this same purpose, the outer or free end of the head is preferably cut out, as illustrated at- 48. Slidably mounted on the stem 46, is a gage L9 that is disposed in advance of the cutting edge of the blade and has a boxing 50 that receives said stem. An adjusting screw 51, journaled in the boxing, has a threaded engagement, as shown at 52 with the stem. Consequently by turning the screw 51, it will be evident that the gage can be adjusted toward and from the cutting blade. The gage, as shown, tapers toward its front end, and is provided with a narrow shoe or flange 53, which will operate through the gummed surface without becoming choked or clogged with gum.

There are many advantages for the structure as disclosed. In the first place, it will be noted that one hand of the operator can be placed on the handle in line with the cutter, so that the same Working stroke can be secured as with the ordinary hack now in common use. At the same time the depth of the out can be accurately gaged. In this connection, the advantages of the relative adjustment between the cutting blade and gage will be obvious. The structure of the cutting blade and the arrangement of parts are such that there is no liability of the implement becoming choked, inasmuch as free clearance is provided for the chips and the crumbs of loose bark, the discharge end being of greater area than the inlet or cutting end. The securing means for the blade is very effective, and when said blade is clamped thereby, it is firmly fixed against movement on the head.

Another important feature of the invention resides in the blade. Tn the first place, it will be noted that the body of the blade projects beyond the shank. This is advantageous, inasmuch as it places the cutting edge in advance of the head so that the operators hand can be placed in line therewith, but further than this, it provides a sufficient body that will permit repeated sharpening of the blade, before it is worn out. Said blade furthermore may be readily detached in order that it may be sharpened or in order that a new blade may be substituted for it. It will thus be evident that when {it blade becomes excessively worn or useless from any cause, it can be supplanted by a new one without difficulty.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape,

proportion, and minor details of construc-' tion, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
