TWO-IN-ONE CHISEL Filed 001:. I, 19250 San/ey Pen/wilg@ ATTORNEY Patented Sept. 13, 1932 UNITED STATES miese PATENT OFFICE STANLEY rnNxosnr, or New Yoan, N. Y. i l* TWO-IN-ONE CHISEL Application lcd. October 1, 1930. Serial No. 485,741.

The object of this vinvention is the provi-l sion of a chiseling tool that comprises a member provided with two cutting bits and which is designed for easily and expeditiously per- 5 forming a number of functions, such for instance, as the longitudinal splitting of cord wood, the grooving of timbers along scribed lines or the notching of solid newel posts that receive in the said notches the lower step of le a stairway and which tool is characterized hy simplicity in construction and reliability.

To the'attainment of the foregoing the invention consists inthe improvement hereinafterdescribed and definitely claimed.

in the drawing:

Figure l is an elevation of a tool employed for splitting cord wood.

the tool per se.

Figure 3 is a similar view but illustrating a slight modification. y

Figure 4 is an end view looking toward one of the bits.

My improved chiseling tool is constructed of a single piece of hard steel or like material and includes two spaced Shanks 1--1 that are sharpened on one or on both of their faces to provide the outer'edges thereof with bits 2. The shanks 1 merge into inwardly inclined arms 3, and the said arms, at their connected portions have aA central extension in the nature of a head 4. By reference to the drawing' it will be noted'that vthe arms 3, have their outer faces, at the juncture with the shanks 1 substantially flattened, .as at 5, providing shoulders, while in Figure 3 the Shanks 5 are extended or projected a suitable distance above the arms 3 to provide shoulders 6 that are spaced away from the 40 the tool is to be made in di'erent sizes and that the Shanks 1 may be arranged close together or spread a material distance apart. Also it is to he understood that the tool, ex cept for the sharpened bit portions 2 may ,describe y arms. It is, of course, to be understood vthat be round or s uare in plan and when the tool is employed or splitting logs as disclosed by Figure l of the drawing the Shanks 1 have their opposite faces beveled to points toprovide the bit disclosed by the full lines in Fig-v ure 4,- of the drawing. The tool?. when partly forced into the log by the impact of the force of a sledge or the like willcause the log to split into slats in an easy and expeditious manner. The

shoulders

5 or 6 providegja means whereby the hammer may be directed against either of the Shanks and consequently either of the bits.

It will be readily noted that the spaced bits, can be readily arranged upon a scribed line and that a timber may be rooved or split along such line. After the bit has been Figure 2 is an enlarged side elevation of` forced into the timber for a determined distance and a groove in the timber is desired one of the bits may be forced longitudinally through the slots or openings made by thel pair of bits through the impact of force delivered against the shoulder and the shank therefor so that the cut wood can be thus forced out to produce the complete groove. The tool is also especially desirable for use in notching the corners of solid newel osts, which with the ordinary construction o chisels involves a laborious task on the part of the carpenter, as the two bits cutting along the and quickly remove the corner of the newel sts. f While I have herein illustrated a satisfactory embodiment of my improvement my features of invention are capable of extended application and I do not wish to be limited to the s ecic structure herein shown and f .Having described the invention, I claim: A wood working and splitting tool comprising a pair of s aced parallel Shanks having wedge-shaped cutting edgesr and provided at their upper ends with impact surfaces parallel with said scribing linesv on the newel posts will easily ower ends terminating in cutting edges, there being r"inclined arms springing from the upper inner side portions of said Shanks and inclined at equal angles with relation to each other, said arms merging with each other at their u per ends and merging with an upstanding lliead portion,^said head portion being midway between the Shanks and parallel thereto, and provided at its upper end with an impact suree lying parallel with all of the cutting e 0res.

n testimony whereof I aiiix my signature.

STANLEY PENKOSKI.
