Title: Hammer-type tool

Description:
BACKGROUND OF THE INVENTION: 
     The present invention relates to a hammer-type tool. 
     Objects of the invention are to provide a hammer-type tool of simple structure, which is inexpensive in manufacture, assembled and disassembled with facility and convenience, and functions efficiently, effectively and reliably to secure a hammer-type head such as a hammer, an axe, or the like, to its handle in a manner whereby the head cannot slip off the handle in the manner of hammers, axes, and the like, which are forced onto their handles. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS: 
     In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawings, wherein: 
     FIG. 1 is a perspective exploded view of an embodiment of the hammer-type tool of the invention; 
     FIG. 2 is a view, on a reduced scale, of a modification of the embodiment of FIG. 1; and 
     FIG. 3 is a view, on an enlarged scale, partly cut away and partly in section, of the embodiment of FIG. 1 in assembled condition. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     The hammer-type tool of the invention comprises a shafttype handle 1 having spaced opposite ends, one end 2 of which is shown in the FIGS. The handle 1 has substantially the same cross-sectional area except for an end area 3 at the one end 2 of the handle. The end area 3 has a cross-sectional area different from that of the remainder of the handle in a manner whereby the end area extends beyond the remainder of the handle at substantially diametrically opposite points in a pair of spaced opposite protruding portions 4 and 5 (FIG. 3) extending substantially parallel to the axis 6 of the handle (FIG. 3). 
     The end area 3 has a pair of bores 7 and 8 (FIGS. 1 and 3) formed therethrough extending through the protruding portions 4 and 5 in spaced relation substantially parallel to the axis 6 of the handle. Each of the bores 7 and 8 opens at the opposite ends 9 and 10 of the corresponding protruding portion (FIGS. 1 and 3). 
     A hammer-type head which may comprise a hammer 11, as shown in FIG. 2, an axe 12, as shown in FIGS. 1 and 3, or the like, is mounted on the end area 3 of the handle 1 and extends at substantially right angles to the axis 6 of said handle. 
     A metal plate 13 is provided at the end 2 of the handle 1 at which the end area 3 is provided. The metal plate 13 has larger dimensions than the cross-sectional area of the end area 3, so that said plate overlaps the head 11 or 12 for a predetermined border area extending beyond the said end area (FIGS. 1 and 3). The plate 13 also has a pair of holes 14 and 15 (FIG. 1) formed therethrough coinciding with the bores 7 and 8 through the protruding portions 4 and 5, respectively, of the end area 3. 
     An elongated screw 16 extends through the bore 7 through the end area 3 and the hole 14 through the metal plate 13 (FIGS. 1 and 2). An elongated screw 17 extends through the bore 8 through the end area 3 and the corresponding hole 3 through the metal plate 13 (FIGS. 1 and 3). The screw 16 has spaced opposite ends 18 and 19 with a head 20 at its end 18 (FIG. 3). The screw 16 has spaced opposite ends 18 and 19 with a head 20 at its end 18 (FIG. 3). The screw 17 has spaced opposite ends 21 and 22 with a head 23 at its end 21 (FIG. 3). 
     A lock washer 24 is provided on the screw 16 at its end 19, which end extends beyond the end area 3 of the handle 1 (FIG. 3). A lock washer 25 is provided on the screw 17 at its end 22, which end extends beyond the end area 3 of the handle 1 (FIG. 3). 
     A nut 26 is affixed to the end 19 of the screw 16, over the lock washer 24 (FIGS. 1 and 3). A nut 27 is affixed to the end 22 of the screw 17 over the lock washer 25 (FIGS. 1 and 3). Thus, the screws 16 and 17 secure the hammer-type head 11 or 12 to the handle 1 via the overlapping plate 13 (FIG. 3). 
     While the invention has been described by means of a specific example and in a specific embodiment, I do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
