Serial No. 402,089.

This invention relates to hatchets, hammers or similar headed tools and to a method of making the. same, and has for an object to provide a headed tool wherein the head and handleare each made ofa different grade and character of steel, the head and the ham dle being each made of a grade and character of steel best adapted for the purpose for which it is intended.

It is a further object of this invention to provide a hatchet or headed tool wherein the head may be forged of a high grade tool steel which is capable of maintaining a keen cutting edge, while the handle may be separately forged of a high grade ofstructural steel 1 having great strength and toughnessand also in which the head and handle-can be separately heat treated. according to -the character of steel used, to secure theirgreat est adaptability for the work to beperformed by each. j It is another object of the invention to provide a hatchet, hammer or similar tool in-which thehead and handle are so connected that there is no possibility of the head becoming loose on the handle. l 1 Still another object of the invention-is to provide a construction for thistype of device which can be more easily manufactured and at less cost. l

WVith the foregoing and other objects in View, this invention comprises certain condie in a position. about to be welded together.

modified head and handle, and

Structions, combinations and arrangements of parts as set forth, disclosed and claimed in-the following specification considered in connection with the accompanying drawings. In the drawings: 4 Fig, 1 is a side View of a hatchetembodylng one form of this invention.

F ig. 2 is a back plan view of the hatchet of Fig. 1.. I Fig. 3 is a cross section looking in the'direction of the arrows online 3-3 of Fig. 1. Fig. his a section on line 44 of Fig. 1. Fig. 5 shows a view of thehead and hen Fig. 6 isan end elevation of the handle.

Fig. 7 shows a View similar to Fig. 5 of a Figs.8, 9 and 10 are. fragmentary top views contact therewith as .in Fig. 5, .and is then indicating different wa ysby which the ham 7 dlemay be welded to the head. In the construction shownthe hatchet head- 10 includes the, cutting edge 11 on one end.- and the hammer 12 on .theother end andif desired there may he a claw 13 provided in one side; This head10 is preferably made of a high grade tool steel which is capable of maintaining a keen cutting edge at 11. In the form shown in Figs. 1 to 5, which is the preferred form, there is forged integral with the head 10 on the rear edge thereof an ear or lug 14; to which the shank 15 of the handle 16 is to be welded. The shank 15 is preferably made ofxa high grade structural steel having strength, toughness and resiliency and is better adapted to stand'the' strains of useas a handle than it would made of the same steel-as the head. .The head end of the shank 1:5 may be of any de sired shape in cross section, but is preferably and should be substantially; rectangular or oval in cros section, similar. to the lugtor car. 14: and if. butt welded tothe lug is placed in welded thereto. This can be readily done in an clectricfwelding machine which ieats the abutting ends of the lug 14 and the shank or, handle portion 15 and forces them; together in the welding operation. This operation produces a rib 17 all around the welded-joint whichis later ground off so that. to all ap peara'nces the head 10 is forged in one piece with the handle shank 15, and the welded joint is just as strong as if they were forged in one piece. Q v

Altho it is preferred to electrically butt weld the handle to the lug we are by .no means limitedto but welding. Other ways ofwelding may be used as shown in Figs. 8, 9 and 10. As shown in F ig.8 either the end' of the handle or the end of the lug may be provided with a substantially shaped recess 26 and theother member with a tapered also be used for electric welding. Sin'lilarly as shown in:-Fig. 9 the ends of the lugs and handle may be slanting as indicated-at 28 surfaces of the flanges 19, and togive a gen-' so they will overlap and may be welded together in the same manner. In Fig. the overlapped ends are rabbettedas shown at 29 and welded inthe same way.

The shank extends throughout the en.- tire length of the handle 16 and is preferably substantially I-shaped in cross sectionwitha central plate or web 18 and flanges 19 extending laterally from the opposite sides thereof and from bothsides of the web as eral oval shape to the grip, and the handle is given a graceful longitudinal cury' ature as shown in Fig. 1, so that it will fit properly in the hand. These cheek pieces are securely fastened on the opposite sides of the'shank by suitable rivets21, giving a rigid, substantially unitary structure. At their free ends, the cheek pieces are preferably projected outwardly somewhat as shown at 22 to give a sort of rounded enlargement or flange at the end to further improve the grip and prevent tool flying from the users hand.

In the form shown" in Fig.7. the ear or lug 14 has been omitted from the head 23,

and the shank 24 is butt welded directly to the rear edge 25 thereof, electric butt welds i ng being preferably used as in the form pre viously described. In this case, however, it

would be better to preheat the head 23. as

it-isa greater mass than" the shank,"so that the two members or metals'at the point of welding may be of the same temperature,

thereby insuring a firm and secure joint therebetween.-

It is apparent fro'mjthe above'description that this invention provides a tool of this character which is of a very strong con struction in which there is absolutely no danger of the head working loose, that the head being of a high grade tool steel will maintain a keen cutting edge for a greater length of service, and that the handle being made of a shank of high grade structural steel, will have greater strengthytoughness and resiliency to withstand the strains to which it is put,much greater than if itwere made of the same steel as the head. 7

By this construction as above set forth, the head and the handle can each be made of a steel most suitable for the particular job it has to perform, the head to have the requisite hardness to maintain its keen cutting edge,

and the handle tohave therequired strength and resihency and toi'iglineiss, instead of having to compromise and lose some of these deed forv the head, and vice 'versa, the head will maintain its keen' cutting edge much longer than it wouldif it were'made of'the grade or character of'steel'best adapted for use in the handle. Resiliency is a very desirable feature in the handle as it makes the tool much easier on the hand and arm of the user. ith a properly resilient handle less shock from the blow is transmitted 't'othehand and arm and so the toolis less tiring.

.The forging operations are also much easier and much better forgings can be produced by for ing the head in one operation and the handle or shank inanother than where they are forged in one piece. This is a material advantage even when the head and handle are made'of the same grade and character of steeh Further, there is much less breakage and, therefore, less waste in manufactureso that a better article can be produced at less cost. A still further important advantage is that with our improved construction the head and handle can be differ-j ently heat treated to secure their maximum adaptability for the work intended. These heat treatments are controlled according to the steels used and the effect or character desired in the different parts. In short,the

head, and handle. may be each separately forgedof the steel most adapted foruse in these parts and they are? separately heat treated after welding' according' 'to'ithe steels used and the workfthey have to erfo m;

Althoughthe 'handlefhas been shown as bein'g'of I-shape in cross section, it, maybe varied in shape-and may be'elliptic'al or oval; Having thus describedthe invention, what weclaimis: r

1. A hand tool and a forged handle'with an I shape'dshank, theheadend of said shank being filled in be: tween the fiangeson both sides so that this comprisinga striking head,

end portion for a distance from its free end a is of substantially oblong transverse section so as to provide a body, of metalat said end of greater'cros s section than thatJof the I- shaped section, said head being a forged head with an integral. lug projecting from one side thereof of'an'oblong crosssection substantially .the same as the head end of the shank and arranged withits greatest'width in the plane of the head,and said free end of the shank being welded to the free end of the lug with the web of the shankextending the plane of the head. a g

2. A hatchet comprising a forged handle including a grip'portion; and an integral shank of substantially I-shape in cross section, the head end of said shank being filled in between the flanges on both sides so that this end portion for a distance from its free end is of substantially oblong transverse section to provide a body ofmetal at said end of greater cross section than that of the I- shaped section, said head being a forged head having an integrallug of an oblong cross section substantially the same as that'of the head end of the shank projecting laterally from one side edge of the head and arranged with its greatest width in the plane of the head, and said free end of the shank being welded to the free end of the lug with the web of the shank extending in the plane of the head.

3. A hatchet comprising a forged handle of steel characterized by strength and toughness including a grip portion and an integral shankof substantially I-shape in cross section, the head end of said shank being filled in between the flanges on both sides so that this end portion for a distance from its free end is of substantially oblong transr verse section to provide a body of metal at said end of greater cross: section than that of the I-shaped section, said head being a forged head of a character of steel to receive and maintain a keen cutting edge and havingan integral lug of an oblong cross section substantially the same as that of the head end of the shank projecting laterally from one side edge of the head and arranged with its greatest width in the plane of the head, and

said free end of the shank being welded to the free end of the lug with the web of the shank extending in the plane of the head.

In testimony whereof we aflix our signatures.
