MAGAZINE HAMMER.

A'pplicatidn filed June 8,

This invention relates to automatic magazine hammers and shingling hatchets and it has particular reference to a novel mechanism so constructed as to select and place a tack or nail in a position to be driven,

in addition to certain'expediences for successively opening and closing the nail delivery passageway at each operation and employing for such mechanism a minimum number of parts.

The invention further aims among its objects' to provide a novel trigger assembly making possible theabove action, as well as a feeding means disposed in such a manner as to progressively hold the nails in a position which will not interfere with the operation of the hammer or hatchet as the case maybe.

With the foregoing objects and advantages in view the invention consists fur' ther in the novel construction and arrangementof parts by which the foregoing objects are attained, and which will be manifested in the course of the following detail description and illustrated in the accompanying drawings wherein:

Figure 1 represents a side elevational view of a hatchet and nail feeding means constructed according to the present invention.

Figure 2 is a fragmentary underside view of the magazine handle, showing the nail feeding means and delivery.

Figure 3 is a fragmentary side elevational view of the invention partly in section, showing the position of the nails alined for delivery.

Figure is a detail view, with portions broken away, of the delivering lever assembly.

Figure 5 is a view of the reverse side of the delivery lever assembly. 7

Nail driving tools of such design as to afford an automatic feeding means are known to have been heretofore advanced with an effort to avoid having to manually place the nail in position for setting with the hammer, and to further expedite the work of such a tool in various ways, therefore the present invention does not claim as new the broad idea of automatically placing the nail for setting with the hammer, but does claim as new and novel, the mechanism described herein. for singly releasing and placing the nail and closing the delivery pas- 1926.

sage against release of the nails, and automatically opening such passageway for the reception of another'charge, all of which is accomplished by a single trigger disposed upon the handle of the implement. 7

With the above in view the invention consists primarily of ahollow handle or magazine 1, for the reception of nails or tacks 2, which, as shown in Figure 1, is closed at its end by a plug 3. An opening or channel 4, the depending sides of which are integral with the handle 1 is cut in the undersideof said handle, and is of such width as to permit passage of the nail body but not the head.

Detachably affixed to the forward end of the channel 1 is a delivery chute 5, slightly inclined toward the ball of the head 6, and, as shown in Figure 3, is likewise equipped to receive only the heads of the nails 2 and permit the same to slide freely downward, after having been released through the enlarged aperture 7 in the handle by gravity. Referring more particularly to the transfer of the nails from the handle to the chute 5; the nails after having been placed in the handle 1, finally assume a uniform, perpendicular position therein as in Figure 8, and upon swinging the hammer in driving, the column of nails move forward and are held from displacement when entering into the delivery chute by the depending tongue 8, see Figure 3. The nail heads pass beneath this tongue and pass through the opening 7 onto the shoulder provided within the chute 5 and downward to where they are stopped by a shoulder 9 at the end-of the chute, as in Figures '2 and 3.

A bracket 10, also preferably integral with the handle 1, depends at the end of the latter adjacent the head 6, and as shown in Figure 5 especially is secured by any suitable means to the lower end of the chute to supportthe latter and positively hold the same in correct position with respect to the head 6. To this bracket 10 is pivoted a pair of co-acting levers 11 and 12, termed herein as a delivery lever assembly. These levers, by reason of the lugs 13 thereon as in Figure 4 especially, have limited independent movement on the pivot 14, with respect one to another, but are adapted to move the greatest distance simultaneously as will be presently disclosed. It will be noted in Figure 1 that the outer lever 11 is provided with a nail receptacle 15,

which is adapted to register with the opening at the shoulder 9 on the delivery chute when receiving a nail and through the action the spring 16, which is secured to the lever and to a rigid part of the chute 5, a closing action of the receptacle is obtained by reason of the lower portion of the lever 12 sliding thereover as particularly apparent in Figure i.

The trigger 17, shown in Figures 1 and 2, is provided with a sheath 18 through which the same passes to where it is pivotally secured to the top of the lever 12. After receiving a nail from the chute 5, forward movement of the levers 13. and 12 to carry the nail into the position shown in dotted lines in l igure l is effected by pulling upon the trigger 17. This action very obviously pivots the two lovers ii and 12, the springs 16 and 19 acting independently upon the levers causes the under lever 12 to which the trigger N is aiiiried, to move forward a limited distance in advance of the outer lever 11, such action causing the lower portion of the former lover to move to e iclose the nail received in the r ptacle 15, such an action likewise closing the discharge end of the chute 5 to shut oil the remaining nails by the smooth inner surface of the le'vervli as the two lovers move forward, Figure Now, when the nail is in a position below the shoulder 20 integral with the head (3 for striking, the latter action is carried out to set the nail while the trigger 17 is held with the linger. llhcn the nail is set, the trigger is released and the springs 16 and 19 return the levers ll and 12 back to their normal positions, and since the receptacle 15 is provided with a lip 21, see Figure 2, to, prevent its passage by the shoulder 9 of the receptacle 5, the lever 11 is stopped at this point, while the tension of the spring 19 upon the companion lever 12 causes the latter to move a limited. distance lteyond the opening in the chute, suiiicieut to permit another nail to fall within the receptacle 15, and the setting actionis repeated.

From the foregoing, it will be readily seen that there is no possibility of clogging of the na'ls at the point of transfer from the handle 1 to the chute 5, nor from the latter to the receptacle 15 of the lever 11, and in the latter action, the delivery of only a single nail insured by the co-active relationship ot the two levers ll and 12. aided by the springs 16 and 19, when the trigger 17 is actuated.

lVhile the invention has been described as including all the elements referred to in the appended claims, it should be understood that certain minor changes and modifications may be resorted to as to form and assembly of parts tall within the meaning and scope of the said claims.
