OLIVER KING, OF CLEVELAND, OHIO.

WOOD-SHOPPING. AX.

SPECIFICATION forming part of Letters Patent No. 427,088, dated May 6, 1890.

Application filed August 16, 1889. Serial No. 321,026. (ModeL) T0 at whom it may concern.-

Be it known that I, OLIVER KING, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Vood-Chopping Axes; and I do hereby declare that the following is a full, true, and exact description thereof.

My invention is an improved ax, and is fully illustratedin the accompanying drawings, in which Figure 1 is aside elevation, and Fig. 2 a rear elevation, of the ax. Fig. 3 is a section on line m 00, and Fig. i a like section on line 11 y, of Fig. 1.

In the drawings, A represents the head of the ax, and B the cutting-edge. The ax-body is contracted centrally, as at a, the blade or cutting-edge B flaring outwardly from the joint, while the head enlarges in the other direction.

It will of course be understood that the particular configuration shown is not material.

The main feature of the improved axis the central ridge 1), which begins with the full thickness of the ax at the head at the point C and extends at a gradual inclination, as shown in Fig. 2, to the point (I just above the cutting-edge, the inclination being such as to gradually merge the ridge into the cutting-edge. From the point e to the point (I the ax slopes outwardly to the sides and upwardly and downwardly, leaving the ridge the thickest part of the ax between the points named. Thus the ridge forms the apex of the inclined portions on either side thereof, gradually tapering off, however, as it approaches the cutting-edge, and when the a2; is driven into the wood this ridge acts as a wedge and by sustaining the pressure of the wood relieves the otherparts of the surface from frictional contact. This increases the wedge effect without bringing into use the whole surface of the blade, and provides also for the easy withdrawal of the blade for another blow.

\Vhat I claim, and desire to secure by Letters Patent, is

An ax having a central ridge extending between the head and the blade, with the sides sloping away from the ridge throughout its extent, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

OLIVER KING.
