KAMER.

This invention relates to hammers, partie-- ularly those used in work where it is neces` sary or desirable to have a more or less soft striking surface of metal such as lead or copper as distinguished from iron or steel.

Its object is to provide such a hammer which the soft metal striking surface or surfaces may be replaced as worn out without disturbing the rest of the hammer, thereby greatly cheapening the cost of repair or reconstruction, and to provide a hammer so constructed that the soft striking surface is partially reinforced by the body of the hammer itself, thus rendering such surfaces more durable in use.

The invention consists in cheap and convenient means for accomplishing the foregoing and other objects which will be hereafter more fully set forth in the specification and claims.-

Referring to the drawings in which like numerals denote like parts throughout the several views,

Figure 1 is a face view of the striking surface, While,

Figure 2 is a side view, partially in section of the hammer illustrating this invention in its preferred form.

Figure 3 is a sectional detail view on the line 3 3 of Figure 2.

Figure 4 shows the hammer with a mold or cap applied to the hammer in operative position for casting a new striking block of soft metal into the hammer body.

In constructing the device of this invention, a central body member 10 of relatively hard permanent metal, such as malleable iron or steel, is provided, the same being conyveniently perforated to receive a Wooden handle 12, secured in place by any suitable means, such as the conventional plate 14 and wedge 16.

rI`he hammer body 10 is of generally cylindrical or barrel shaped form extending in Specification of Letters Patent. Patented iwal.. 14, 1922 Application led April 27, 1921.

its upper edge 24, so that when metal 26 or 28, as the case may be, is poured into it and allowed to solidify, it is permanently locked in the chamber.A f

Near the entrance edge 24 of each of these chambers, the side Walls of the striking head are reinforced by cross webs 30 and 32 clearly shown in Fig. 3 intersecting each other in such a manner as to form a plu- -rality of, angular cross section, passages 34 adapted to receive the softer metal 26 or 28, as the case may be. The presence of these we bs in the soft metal serves to further lock it 1n place in the striking head.

Having provided the parts thus described, the constructor places first one then the other of the striking heads in a suitable mold, not entering into this invention and casts into its chamber described, or recess as 18, a quantity of relatively soft metal 26, say lead, forming in casting on the finished product a striking block 36 of that metal. The constructor may, if he likes, put the same material in the other recess 20, but by preference he will place therein some metal of a different degree of softness from that first used, say copper, forming of that metal at the other end of the handle a striking surface 38.

When the hammer thus constructed is used, the striking surfaces 36 and 38 are reinforced by the edges 24 of the adjacent portions of the hammer body l0 and are thus prevented from unduly rolling down at the edges prior to the time the entire soft striking surfaces 36 or 38 have been more or less evenlyl worn away. When this latter condition occurs the operator can place either one of the striking heads of the hammer with or without the handle 12, 2still in central position, in a suitable fire and melt out the used and damaged soft metal body 26 or 28 as the case may be, and recast a new one therein, whereupon that striking head is ready for immediate use just as though it were a new one.

As a convenient means of casting the soft metal body 26 or 28 the hammer is when sold preferably but not necessarily equipped with a mold 40 of cast iron or the like adapted to be slipped over the striking end of the hammer body as shown in Figure 4. The inner edges of the mold are provided with angular faces 42 adapted to Wedge onto the outer edge of the hammer body and make a tight joint. In the top of mold` (as it appears in lthe metal is poured. A Zhen metal has been so poured into the device and allowed to cool in the form of member 36 or 38 the mold A40' is easily removed and the hammer is complete.

Having thus 'described my invention, what I claim as new and desire'to secureby L'etters Patent, is

l. A soft .nose hammer comprising a body portion` provided with ay transverse `'handle receiving-opening and an end recess, -a web Vdisposed entirely within said recessin spaced relation to said'handle receiving opening,

and afstrikingf head cast intov said recess `and around said. web, a portion of said striking head material being-disposed between the portion having a recess in each end, said body4 portion including an intermediate portion provided with a transverse handle receiving opening and separating said end recesses, a transverse web disposed entirely within and spaced 'from the outer end of each recess, said webs also being spaced from 'said interlnediefmr` portion, and striking heads cast into said recesses around said webs and projecting --beyond the respective ends of said body portion.

In witness whereof, I have'hereunto subscribed my name in the presence of two witnesses. f
