HAND-TOOL.

y No. 894,303.

Specification of Letters Patent.

Patented 'July as, 190s.

Application filed August 28, 1907. Serial No. 390,499.

T0 all whom. 'it may concern.'

Be it known that I, GEORGE E. Woon, a citizen of the United States, and a resident of Southington, in the county of Hartford and State of Connecticut, have invented a new and Improved Hand-Tool, of which the fol lowing is a specification.

. My invention relates to the class of tools embodying a wooden handle fixed to a metallic part, and more 'especially tothe class of carpenters tools such as chisels, screwdrivers and the like. i

T he. object of my inventi'onis to produce a tool of this classthat shall be extremely durable, cheap in construction and especially one that shall be neat and sightly in appearance.

A form of device i'n which these objects are embodied is illustrated in the accompanying drawings in which Y Figure 1 is a view of a blank with a handle (cut'in section) fixed thereto showing a preliminary step in the operation. 'Fig 2 is -a similar view, with the ferrule broken .away

and showing a succeeding step. Fig. 3 is a side view of a device showing still a further step in the operation. Fig. 4 is a side view showing the completed tool.

In the construction of the class of tools embodying screw-drivers, chisels and the like, and especially in the manufacture of chisels, it is desirable that the shank of the blade shall extend entirely through the handle and be formed into a head for the purpose e' of receiving blows in the customary method of using the tool. This construction avoids mutilation of the wooden or other fibrous handle with which the tooll is su plied and thus greatly prolonge its life, the andle of a tool thus constructed in fact being practically as long-lived as the tool itself.

In order to maintain the handle Within proper limits as to size it is necessary thatthat portion extending through the handle f shall not exceed certain proportions. In the manufactureof screw-drivers, with a blade of limited width, this has been a comparatively easy matter for the reason that the blade could be drawn from a piece of stock of the size of that extending through the handle. It has been a more serious question, however, to obtain a blade of considerable width as is necessary in the manufacture of chisels for the reason that-the size of stock sufficient for the shank located within the then the blade finished.

handle has not been of snicient size to produce a blade of proper width.

In the ractical form of construction of such a'tooi) it is essential that the head shall first be formed, the handle of wood or other fibrous material placed upon the shank and In this finishing of the blade great care must be taken, in any heating thereof, in order to avoidinjury to the handle of wood or other fibrous material from such heat, and in fact this liability of injuring the handle by heat has limited the size of the blade which could be produced on a tool thus formed. A

" In carry-mg out my invention I have demonstrated that a tool may be thus formed with-a blade of any desired width, the man ner of constructing such a tool being shown in the accompanying drawings in which a blank of proper length and of a uniform size in diameter the same as that of the shank to be located within the handle is provided. This blank is divided into the blade portion 5 and shank portion 6 and a head 7 is formed upon the end'of the latter. Theshank )ortion is also reduced as at 8 forming a sho ulder 9. A handle l0 of wood or other fibrous material is then placed upon the blank and closely fitted against the head 7. This handle is formed after the general manner of what is known as a socketed handle, the inner end thereof being formed with tht` socket piece 11 terminating in the shoulder 12. A ferrule 13 is fitted u on the socket piece, lying-closely against t e shoulder 12 and projecting some distance beyond the socket piece, as plainly shown in Fig. l, the inner end of this ferrule lying in position adjacent to the shoulder 9 of the reduced portion or groove 8. The ferrule is now swaged into the reduced portion or groove 8, so that the ferrule in factforms practically an in# tegral part of the shank 6, and as .shown'at 14 in Fig. 2. This swaging'and union of the ferrule and shank may-be performed after any of the Well-known methods to cause the shank to be practically an integral part of the ferrule. In this swaging operation the blade portion 5 of the handle is reduced as at'15 thus causing the blade to ap roach the final stock of a size equal to that desi but I have foundv that this heating can be done Without injuring the handle to any material degree, and especially is this the case when the construction herein shown removes that portion to be heated to a considerable extent from the handle of wood or other fiber. After the blank has been upset asv shown in Fig. 3 the tool may be inished by drawing the blade 17, as shown in Fig. 4 of the drawings.

It Will be noted that from this construction a tool as a chisel of any width desired may be easily and cheaply made lfrom a ieee of '.redPfor-the part located-within the handle. The handle of w'ood or other fibrous material is first placed upon the shank and then without in- ]ury to this handle the blade is formed as above described. The tool while constructed with the shank and head integral with the blade, and the resulting advantages, has also the appearance of the more sightly socketed tool. In fact the tool is a combination of a socketed handle tool and a blade with a shank with all the advantages appurtenant to both.

It will be noted that by swaging the ferrule into the groove 8 all ofthe parts are securely held by abutting'shoulders, and Whether the ferrule is swaged or welded to the shank 6, toV

form an integral or practically integral part thereof, within the purview of my invention, the union will be so closely made as to give to the tool the appearance of a tool of socketed construction, the entire metallic surface bein t ractically smooth and the joint between the errule and shoulder 9 being practically eliminated in the nishing operation, as shown in Fig. 4 of the drawings. A

What I claim as new and desire to secure by Letters Patent is A tool including a shank with a head- GEORGE E. VOQD.
