HAMMER Filed May 22, 1939 2 Sheets-Sheet 2 Attorneys Patented Mar. 12, 1940 Leslie John Rapien, Chicago, Ill. Application May 22, 1939, Serial .No. 275,069

The present invention relates to new and useful improvements in hammers of the handle magazine type for use particularly by lathers and roofers and has for its primary object to provide, in a manner asv hereinafter set forth, a tool of this character embodying novel means for delivering nails one at a time to the head I of said device to be started.

Other objects of the invention are to provide a hammer of the aforementioned character which will he comparatively simple in construction.

strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured, at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is'a view in side elevation of a magazine hammer constructed in accordance with the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a view in vertical longitudinal section through the tool, taken substantially on the line 3-3 of Figure 2;

Figure 4 is a view principally in side elevation but with a portion broken away in longitudinal section through one side portion of the device.

Figure 5 is a cross sectional view, taken substantially on the line 5-5 of Fig. 3.

Figure 6 is a detail view in perspective of the plunger.

Figure 7 is a detail view in perspective of the follower. v,

Figure .8 is a perspective view of one of the nails.

Figure 9 isa view in side elevation of a portionof a strip of nails to be mounted in the magazine.

Referring now to the drawings in detail, it will be seen that the embodiment of the inven tion which has been illustrated comprises a handle l of any suitable .dimensions and material, said handle including finger receiving indentations 2 on one end portion. On the other end of the handle I is a head which is designated generally by the reference numeral 3.

As illustrated-to advantage in Figs. 3 and 4 of the drawings, the handle constitutes a magazine for the reception of nails 4'. Toward this end, the handle I has formed therein and extending from end to end thereof a substantial- 1y T-shaped groove or channel 5 for slidably receiving the correspondingly shaped nails 4. Communicating with the groove 5 is a longitudi-, nal slot 6 in the upper portion of the handle I. Operable in the groove 5 is a substantially T- shaped follower l of suitable metal which is adapted to feed the nails 4 to the head 3 of the hammer. Rising from the topof the follower l is a headed ,pin or the like 8 which the slot 6 accommodates. On the forward end portion of the 10 handle I is a substantially segmental casing 9 in whicha clock spring I0 is mounted. The clock spring in emerges from the casing 9 and extends along the upper portion of the handle I and terminates, at one end, in a loop II which is en- 35 gageable with the pin 8 for connecting the follower 7 to said spring ill for actuation thereby; The free end portion of the elongated loop It is turned upwardly at an angle in a. manner to provide a grip H2.

The head 3 comprises an elongated housing l3 which is substantially square in horizontal section, said housing being of any suitable metal. of course, the housing l3 extends at right angles to the handle I Mounted in the upper end portion of the housing I3 is a hatchet blade l4. Mounted in the lower end portion of the housing I 3 is a striking member or nose of suit-' able metal.

Mounted in the lower rear portion of the. housing [3 is a vertical guide is the upper-portion of which communicates with the groove 5 in the handle I for receiving the nails 4 therefrom. It may be well to here state that the guide I 6 will receive but one of the nails 4 at a time. The nail slideway in the guide It extends through the nose l5, as at IT. Mounted for vertical movement in the housing i3 is a plunger I8 of suitable metal. Mounted on the rear of the plunger l8 and extending in spaced parallelism therewith is a finger I9 which is operable in the guide It. Formed in the plunger M at an intermediate point is a recess or notch 20. The recess or notch 20 is for the reception of the forward end portion of a spring projected latch 2| which is slidably mounted in the handle I and which extends'into the housing I3. A retracting or disengaging handle 22 is provided on the rear end of the latch 2|, said handle being operablein a longitudinal slot 23 which is provided therefor in the handle I. "In Figure 9 of the drawings, there is illustrated a portion of a strip of the nails 4 which are secured tosether by adhesive tane 24.

It is thought that the manner in which the tool V is used will be readily apparent from a consideration of the foregoing. Briefly, the clock spring "I is disconnected from the follower 1 and said follower is removed from the handle I. A strip of nails is then inserted in the groove 5 of the handle I, after which the follower l is placed insaid groove behind said nails and the clock spring Ill again connected thereto. Thus, the nails 4 are being constantly urged forwardly in the handle I toward the head 3. However, as hereinbefore mentioned, only the forwardmost nail may enter the guide It. The surface into which a nail is to be driven is then struck with the head 3 and when this occurs the plunger I8 is caused to move downwardly in the housing l3 by inertia. In this manner the finger I9 is moved downwardly in the guide l6 carrying with it the forwardmost nail which is therebeneath and impaling said nail in the surface which has been struck. The nail is thus started. When the'plunger I8 isin lowered position it is locked by the engagement of the latch 2| in the recess or notch 20. The driving of the nail may then be completed. The latch- 2| is then retracted in the housing l3, as seen in Fig. 3 of the drawings. The spring l0, throughthe follower I, then 30 functions to move the next nail into the guide l6 beneath the finger I9 and the tool is ready to repeat the above described operation. A spring pressed pawl 25 is pivotally mounted in the'head I3 and operable in the guide l6 for preventing the nail in said guide from dropping out.

It is believed that the many advantages of a magazine hammer constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A hammer of the class described comprising a handle having a longitudinal groove therein for the reception of nails, a head on one end of said handle, said head including a housing, a guide inv said housing communicating with the groove in the handle for receiving the nails therefrom one at a time, a spring actuated follower in the groove-for feeding the nails to the guide, a

plunger slidably mounted in the. housing, a'finger on said plunger operable in the guide and engageable with the nailsfor ejecting said nails from the head, and a spring projected latch slidably mounted in the handle and engageable with the plunger for releasably locking said plunger in lowered position.
