The head 8 is prokt l2.-" The had is-provided with an integral Within the handle' portion menu the adjacent head Hi there is rotatably mounteda cylindrical magazine l8. As clearly illustrated the magazine ls s rotatably mounted within the handle on the a w spindle 20 theuppr end of whichextends into an "5 aperture in the wall of the handle, the' cylinde'r being heldiii position by means of the screwthreaded mg' 22 into which in an aperture there'- in there extends the lowerp'in24. flhe cylinder 1a is provided w th s plurality of spaced longitudinally extehamghhn receiving slots 26; In the tubular handle l'4 there is arranged a nail receiving magazine which is provided with aplurality of spaced verticallongitudinally ex- K tending nail receiving slots so e as; (nearly illustr'ated the upper portion of the magazine terinitiates short of the inner side of the handle to permit of the passage of the heads of the nails through the heir receivjngslot in the handle.

The nail receiving pocket I2 in the magnetized hainmi head 10 is in communication with the rijtatahly mounted magazine [8 through the medium of the longitudinally extending slot 34. on the bottom of the rotatalbly nfi ounted magazine l8 t ere is provided a; ratchet w eel 36 actuated by rhe'aghs er the trig'gijrod 40 which is slidably dis pe eajh :grdgv in the side ofthe handle M. The ratchet wheel is prevented from freely rotatii ig bye; resiliently mounted pawl 44 secured t @1 5 id d? the han On ed trigger to rod l ll ispointed and adapted to engage as clearly illustrated in Figure4 the ratchet wheel and the other end thereof extends upward'throug'h an opening or aperture in the slot of the handle defining a trigger. The trigger rod 40 is normetny maintained in and out of engagement position with respect tothe ratchet wheel 36 by means otthe' spring 46 coiledthereabout. It will thus be seen that upon actuation of the trigger 48 the trigger rod 4}) is pushed into engagement with 40 one of the dogs of the ratchet wheel 36 causing intermittent rotation thereof to present one of the vertical sltits into registry engagement with the longitudinally extending slot 34 to the end "stick hi' the material aha upon the application of repeated blows o'n'the head l0 can be. driven therein. I

As clearly illustrated the forward end of the nail receiving magazine 28 is of arcuate shape and is disposed adjacent the'cylindrical magazine l8; Th nails are fed from" the longitudinally extending slot 30 in the magazine 28 to the slot in the rotatable magazine by means of a gate 52 which is slidable in a longitudinally extending slot 54 in the cover. It is to be noted that the gate which is slidable beneath the magazine and the underneath side of the cover I6 is of inverted U-shape and has spacedly downwardly extending arms 56, the terminal ends of which are up turned as clearly illustrated. The inverted U- shaped cross member 58 is provided'at its midpoint with a threaded aperture into which there is screw-threaded the set screw 60 which slidesin the longitudinally extending guideway or slot 54 in the handle. The gate may be ,fixedly'secured at predetermined position through the medium of the adjusting nut 64. The nail receiv f ing magazine 28 is held in the handle by means of the cap 68 which is resiliently securedthereto by means of the spring I0. Obviously upon an advancement of the gate, or a hammering movement of the hammer the nails in the longitudinally extending slots will be moved forwardly and pass down the inclined guideways into the vertical slots of the cylinder which register with the slot 30 for subsequent movement upon actuation of the trigger 48 to a nailing position. It is to be noted in this connection that the head of the hammer is constructed of a hard material to the end that the frequent hammering and contacting therewith will not cause the same to lose its magnetic properties, as would be the case if the same were constructed of a soft material.

Referring now more particularly to Figure 7 illustrating a modified form of the invention it will be seen that the hammer is substantially the same as that illustrated in the previous figure with the exception that the actuating rod or trigger is in the form of a push lever I6 disposed above the nail magazine 28. One end extends through an aperture in the handle and is slightly curved as illustrated defining an actuating trigger I8 to be actuated by pushing the same forward with the thumb. The other end of the actuating rod I6 is provided with a ratchet which cooperates with the teeth on the cog wheel 82. The push rod I6 is' normally maintained in its out-of-engagement position by means of the coil spring 84 disposed in the pocket in the handle and surrounding the rod. As clearly illustrated, the forward end of the spring abuts one side of the pocket and the other end normally engages a stop 88 secured to the push rod I6. It will thus be seen that upon the forward pushing of the rod I6 the ratchet of the rod engages the cog wheel 82 to intermittently rotate the rotatable magazine 90 of the same construction as the magazine previously described in the other figure to present one of the slots containing a nail in registering engagement with the groove 96. The nails fall through the slot 96 by means of the magnet I00 secured in a pocket in the head of the hammer. The magnet I00 has a circumferentially extending groove in the upper end thereof into which there is received a set screw I02 extending transversely in the hammer for securing the magnet I00 therein. The magnet I00 is provided with a nail receiving pocket similar to the pocket previously described in the other figures to the end, that the magnetic attraction of the magnet I00 causes the nails to'be pulled into the nail receiving pocket from the slot 96.

While there is shown for the purpose of illus tration only preferred embodiments of the invention, it is to be understood that it is capable of various changes and modifications without ing spaced nail receiving grooves therein and adapted upon rotation thereof to register with thelongitudinally extending nail receiving grooves, said hammering head being magnetized .,and having a nail receiving pocket therein, said handle having a longitudinally extending slot communicating the grooves of said cylindrical magazine with said nail receiving pocket, and means for intermittently rotating said cylindrical magazine to effect a registering of the nail receiving grooves of the cylinder with the slot whereby a nail may be selectively brought into nailing position in the pocket of said magnetic head. 7-

V 2. In a device of the class described having a hollow handle and a magnetized hammering head, a nail magazine in the hollow handle having spaced longitudinally extending nail receiving grooves therein, a rotatably mounted cylindrical magazine in said handle disposed adjacent said head having nail receiving grooves therein adapted upon rotation of the magazine to register with the longitudinally extending grooves in the magazine in the handle, said magnetic head being provided with a vertically extending nail receiving pocket, a slot communicating the pocket with the nail receiving slots in the cylindrical magazine, a ratchet wheel on one end of said cylindrical magazine, a pawl for normally maintaining said cylindrical magazine in position, and a trigger mechanism engaging the cogs of said ratchet wheel for intermittently actuating the same to effect the intermittent registering of the longitudinally extending nail receiving grooves in the magazine with the slot communicating with the nail receiving pocket in the hammer and the longitudinally extending grooves in the magazine in the handle.

3. In a hatchet having a hollow handle and a hammer head, a nail magazine therein having a longitudinally extending nail receiving groove, a rotatably mounted cylindrical magazine in said handle adjacent said head having spaced nail receiving grooves therein adapted upon rotation thereof to register with the longitudinally extending nail receiving groove, said hammer head including a magnetized portion and having a nail receiving pocket therein, said handle having a longitudinally extending slot communicating the grooves of said cylindrical magazine with said nail receiving pocket, and means for intermittently rotating said cylindrical magazine to effect a registering of the nail receiving grooves of the cylindrical magazine with the slot whereby a nail may be selectively brought into nailing position in the pocket of the hammering head.

4. In a hatchet having a hollow handle and a hammer head, a nail magazine having a lon gitudinally extending nail receiving groove therein, a rotatably mounted cylindrical magazine in said handle adjacent said head having spaced nail receiving grooves therein adapted upon rotation thereof to register with the longitudinally extending nail receiving groove, said hammer of the cylinder with the slot whereby a nail may be selectively brought into nailing position in the pocket of said magnetic head.
