WILLIAM R. MUNZER, OF EMETTA, MINNESOTA.

Specification of Letters Patent. Padtnld bility ,2d- 11321 Application mea December 2o, 192'0. serial No. 431.971.

i To all Jw Ito/m z'tmcy concern Be it known that' I, WILLIAM It. MUNZER,

a subject of Germany, residing at Emetta,

in the county of St. Louis and State of vMinnesota, have invented certain new and useful Improvements in Axes, of'which the following is a specification, reference being had therein to the accompanyingl drawing.

This invention relates to certain improvements in axes and has special reference to a lumbermans ax for use in getting out pulp 'wood, ties and the like and is an improvement over my Patent No. 1,330,213 of Feb. 10, 1920, the principal object being to provide a more practical and useful instrument than heretofore known.

Another obj ectof this improvement is to provide means whereby the handle of the ax after becoming badlyworn is prevented from slipping forwardly longitudinally through the ax head.

Still another object is to provide a form of such ax exceptionally easy of construction.v

in the further description of the invention.

Referring to the accompanying drawings forming part of this application and in which like reference characters indicate like parts:

Figure 1 is a side elevation of one of the improved axes, y

Fig. 2 is a central transverse sectional view through the ax longitudinally of the handle and showing the .same in active position upon a log;

Fig. 3 is an enlarged broken elevation of two diagonally opposite halves of the edges of the ax, and

Fig. t is an enlarged elevation of theopposite side of the ax to that shown in Fig. 1.

The head of the ax is substantially the form of a common double bitted ax having two arcuately shaped cutting bits 2-2 and withthe handle socket 3 formed substantially centrally thereof as is common, and a third cutting or peeling bit 4 is formed upon the forward edge of the head intermediate of the cutting bits 2--2. However this third bit, instead of being arcuate in form is straight for the major portion of its length, the cutting edge being parallel with the central line of the bits 2 2.

The bit 4 has not only a straight cutting edge but has a fiat external lower surface 5 .disposed at an angle if@ the adjacent back Other objects and advantages will appear i wall 6 of the head of the ax; thus bringing the cutting edge of thebit l1 slightly' above a plane with the inner wall of the socket 3 next thereto.

Just slightly forward and above the angle 7, formedv by the intersection of the surfaces 5 and 6, is formed the shoulder 8 longitudinally ofy the base ofthe bit 4E and which shoulder forms an end wall to the socket 3 in the head of the aX against which the handle 9 abuts when properly assembled within the ax head. This abrupt stop for the end of the'handle 9 is essential in preventing'the latter from being forced through the head of the ax when becoming loose therein as the ax is being employed as a scoop for scooping off the smaller limbs of a tree as shown in Fig. 2.

A still further novel feature of my present improvement is that the upper face of the bit 4; and the upper edge of the ax head adjacent thereto are of the same continuous arcuate plane to both simplify the construction of the ax and `the sharpening`I process thereof, that portion of the end of the handle 9 projecting above the edge of the shoulder 8 being also coincidently shaped as well as the holding wedge 10 which is driven into the end of the handle just above the shoulder 8. The convenience in removing the wedge 10 is seen in that when such is desired that portion of the handle above the wedge and protruding beyond the edge of the ysocket may be cii't off with a chisel and the wedge thus made readily accessible for extraction.

In the removing of branches from tree trunks such as are harvested for pulp wood the ax is used Yas a scoop with the blade l1 engaging the smaller-branches as shown in Fig. 2, while, when a larger branch, as shown at 12. is to be removed, the ax is turned and either of the bits 2 is used as a common chopping ax. When the ax is used for scooping off the branches or for removing bark as is customary in getting out ties, etc., it is very Vessential that the double bulbed handle as shown in Fig. 1 be used, as it otherwise becomes very hard to grip the ax suiiicien'tly for such purpose. i' i Having thus described my invention what I claim and desire to secure by Letters Patent, is:

1. The combination with a double bit-ted ax of the character'describedV having the usual handle socket therein, of a third Scooplike bit extending forwardly of the liront edge of the ax and formed integral therewith, said third bit being disposed at an angle to the axial line of the handle socket, having a straight cutting edge, a straight fiat under bearing surface, and a shoulder at the base of the third bit terminating the handle socket, substantially as described.

2. The combination with a double bitted ax of' the character described having the usual handle socket therein, of a third scooplike bit extending forwardly of the front edge of the ax and formed integral therewith, said third bit socket, having a straight flat under bearing surface disposed at fan angle to the axial line of the handle, and a shoulder longitudinally of said third bit terminating the lower portion of the handle edge of the ax and formed integral there- Y with, and a shoulder at the base of said third bit extending longitudinally thereof and forming an abrupt termination of a portion of the `handle socket.

In testimony whereof I hereunto aix my signature in the presence of two witnesses. WILLIAM It. MUNZER.
