To all 'whom may concern:

Be it known that I, JOSEPH A. JOHNSON, a citizen of the United States, residing at Knight, in the county of Uinta and State of Wyoming, have invented a new and useful Ax', of which the following is a specification.

The object of my invention is to provide an ax having a. removable bit and means for the convenient removal and replacement of such bits, whereby to require a minimum of steel for the ax and the convenient replacing of a dulled bit by a sharp one without requiring a visit to the grindstone.

I attain these and other objects of my ine vention by the device illustrated vin the accompanying drawings, in which Figure l is a side elevation of the devic ready for use;

Fig. 2 is a longitudinal section on the line 2-2 of Fig. 4, approximately, when the bit is applied to the ax body; l

Figf3 is a front elevation of the ax body l when the bit 2 is removed; and

Fig. 4 is a rear elevation of the bit 2 when it is removed from vthe ax body.

several views.

Referring to the accompanying drawings, -I provide an ax body 1 of any desired shape as to its general contour, said body being of malleable iron. projections 3, which have beveled edges 7, as shown in Fig. 3, and with the projection 11, and a corresponding cut-out portion 10 on the other side of the interlocking portion of the ax body. I further provide the cylindrical recesses 9 in projection 3 and recessed portion 4, as shown in Fig. 3.

I further provide, as a new article of manufacture, a detachable steel bitadapted to be removably attached to the malleable iron ax body l, and for this purpose I provide the projection 6 having beveled edges 7 .said projection being of corresponding shape to the recess 4 in the ax body, and having a cylindrical stud 8 shaped to seat in the recess 9; also I provide a similar stud 8 in the recess portion 5 to interlock with therecess 9 and projection 3 of the ax body. I also provide the projection 11 adapted t'o seat in recess 10` of the ax Ibody; and a recess l0 to receive the projection l1 of the ax body; thus providing overlapping members at both the distal and proximal edges of the ax body and bit. I further provide orifices v14 extending through members 11a-nd 13 Ax body l is provided with y atboth the' distal and proximal edges the ax, ysaid orifices 14 being countersunk at each sidek to receive suitable small rivets l2, i

as shown in Figs. l and. 2. In using my invention the lumberman carries a number of the steel bits 2 so that when the cutting edge of one bi-t gets chiped,'broken, or worn out,

it can readily be detached and replaced bv a fresh steel'bit, thusmaking an ax that is far cheaper in the long run than the conventional ax, and eliminating the loss of time and trouble of frequently sending the ax to the grindstone, as heretofore. f

I am aware that axes have heretofore been made having certain resemblances to this device, but without the convenient detach,-`

able bit of steel on a malleable iron or soft 'i i steel body, which is the novel feature, in connection with the improved means for attaching and detaching same, disclosed .in

my invention, and which distinguishes itl from .various axes that are made by poury ing vthe iron through the bit in manufacturing, and which are solid when finished.

Vhat I claim is: f I

1.Inan ax, the combinationfof a bodyl of i malleable iron or soft steel, said body having a'seriesI of aligned diagonally bevelled projections and recesses and also having angu-v larly recessed portions adjacent the distal and proximal edges ofr the ax, and a relatively narrow steel bit having correspond#v ing projections and recesses adapted to seat in and interlock with the recesses and projections of the ax body, and means for riveting the overlapping portions of the bit and ax body together to provide a replaceable bit. Y

2. As a new article of manufacture, a nar row' detachable steel bit adapted to be removably secured to an ax body suitably shaped to receive same but of less expensive material, the ax bit having an intermediate projection having parallel diagonally bevelled sides, and having opposite end projections, one if said projections having a side bevelled diagonally and in a reverse direcf ico tion to that of the intermediate projection.

3. As a new article of manufacture, a narrow detachable steel bit adapted to be removably'secured to an axybody of yless expensive material, said bit having a plurality of projections, two of the projections `having reversely bevelled lateral faces. the projections including oppositely disposed end projections extending part way across thev said body having a series of projections, two:

of the projections 'having their faces reversely bevelled, the ax also havingy recessed 10 openings for'studs, and :t steel' bit of rela.-

tively narrow Width throughout, seid bit having e series of projections and recesses adapted to interlock. With the recesses and projectionsof thegex body and including op-. positely bevelled lateral faces on two ot the projections, central studs positioned to project into recessed portions ot the ax body, and means for releasiblyirivetingfthe bit to the ax body, substantially as described.
