means of compression springs 30. The contacting edges of the dogs are concave, as shown in Fig. 3, so as to force the nails to an axial position in the bore 2|.
The frame I3, grip I4, and chamber I may be formed from two similar, opposite-hand halves held together by means of suitable rivets or clamp screws 3|. These elements, however, could be formed from a single cast or molded block of material such as aluminum or plastic; if desired.
In use, the chamber I5 is filled with nails and the rearward extremity of the rod 22 is inserted in the hammer I0. The head of the frame I3 is placed against the surface of the work 32 at the point where the nail is to be driven. The riveting gun I0 is then pulled rearwardly from the frame I3 (see Fig. 2). This causes the hammer head 33 to enter the head socket 26 in the injector block 23 and pull the block 23 rearwardly against the action of the spring 25.
When the forward face of the injector block 23 passes the head of the lowermost nail, the gun III is pushed forwardly. This allows the spring 25 to push block 23 forwardly with the tooth 2l in contact with the head of the lowermost nail. This pushes the latter nail forwardly, its head being supported by the ledges 35 until the latter terminate at the discharge passage 20 allowing the head of the foremost nail to fall into the bore 2|. Further forward movement of the gun pushes the hammer head 33 against the nail and the vlatter pushes the nail between the dogs 28 and against the Work.- l l The riveting gun; |0 is now operated to reciprocate its drive piston I2 against the extremity of the rod 22, which in turn forces the head 33 to drive the nail into the work, as shown in Fig. 1. The driving is continued until the head 33 passes between the dogs 28 and against the work 32, thus completely driving the nail into the work. The next nail is then fed into the bore 2| by pulling the riveting gun I 0 rearwardly from the frame I3 as before. v
While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent is:
1. A nail driving attachment for power hammers comprising: a frame member; a horizontal bore in said frame member; a driving rod extending axially of said bore and projecting from the rear of said frame member; a driving head on said rod within said frame member; means for attaching the rearward extremity of said rod to a typical power hammer; a nail feeding chamber above said bore, having a width slightly in excess of a single nail for holding a vertical pile of nails above said bore; head channels in each side of said chamber for receiving the heads of said nails; horizontal head channels in the sides' of said chamber at the lowerextremity of said head channels for allowing the heads of the nails to move forwardly in said chamber; and a vertical feed channel at the forward extremities of said' head channels, allowing the heads of said nails to drop into said bore forwardly of said driving head.
2. A nail driving attachment for power hammers comprising: a frame member; a horizontal bore in said frame member; a driving rod extending axially of said bore and projecting from the rear of said fra-me member; a driving head on said rod within said frame member; means for attaching the rearward extremity of said rod to a typical power hammer; a nail feeding chamber above said bore, having a width slightly in excess of a single nail for holding a vertical pile of nails above said bore; head channels in each side of said chamber for receiving the heads of said nails; horizontal head channels in the sides of said chamber at the lower extremity of said head channels for allowing the heads of .the nails to move forwardly in said chamber;
a vertical feed channel at the forward extremities of said head channels, allowing the heads of saidnails to drop int-osaid bore forwardly of said driving head; and means for moving said headsforwardly in said horizontal head channels.
3. A nail driving attachment for power hammers comprising: a frame member; a horizontal bore in'said frame member; a driving rodextending axially of said bore and projecting from the rear of said frame member; a driving head on said rod within said frame member; means for attaching the rearward extremity of :said rod to a typical power hammer; a nail feeding chamber above said bore, having a width slightly in excess ofa single nail for holding a vertical pile -of nails above said bore; head channels in each side of said chamber for receiving the heads of said nails; horizontal head channels in the sides of saidr chamber at the lower extremity of said head channels for allowing the heads of the nails to move forwardly in said chamber; a vertical feed channel at the forward extremities of said head channels, allowing the heads ofsaid nails to drop into said bore forwardly of said driving head; an injecting block mounted on said rod adjacent said horizontal head channels; means on said block lfor engaging the head of a nail positioned in said latter channels; means for reciprocating said block to force the nails forwardly in said horizontal head channel; and a vertical feed channel at the forward extremities of said horizontal channels, allowingthe heads of said nails to drop to said bore forwardly of said driving head.
4. A nail driving attachment for power hammers comprising: a frame member; a horizontal bore in said frame member; a driving rod extending axially of said bore and projecting from the rear of said frame member; a driving head on said rod within said frame member; means for attaching the rearward extremity of said rod to a typical power hammer; a nail feeding chamber above said bore, having a width slightly in excess of a single nail for holding a vertical pile of nails above said bore; head channels in each side of said chamber for receiving the heads of said nails; horizontal head channels in the sides of said chamber at the lower extremity of said head channels for allowing the heads of the nails to move forwardly in said chamber; a vertical feed channel at the forward extremities of said head channels, allowing the heads of said nails to drop into said bore forwardly of said driving head; an injecting block mounted on said rod adjacent said horizontal head channels; means on said block for engaging the head of a nail positioned in said latter channels; a vertical feed channel at the forward extremities of said horizontal channels, allowing the heads of said nails to drop to said bore forwardly lof said driving head; a spring constantly urging said injecting block forwardly to force 5 nails forwardly in said horizontal channels; and means on said rod for engaging said block to move 1t rearwardly.
