To all whom t may concern:

i Be it "known, that I, JOHN MALMGREN, a

citizen of the United States, residing at Cei resco, in the county of Saunders and State of Nebraska, have invented a new and useful ./'N ailing Implement, of which the following is a specification. y f

This invention relates to magazine hatchets, hammers, and similar tools, and has for its object-to provide an inexpensive and eicient tool of this character inwhich the nails -or tacks are automatically fed from the movab magazine to the driving-head of the tool, so that the nails may be successivelypositioned and driven without necessity of handling the same. f

l A further object of the invention is to provide a nailing implement having a magazine detachably secured thereto and formed with .a recess or opening normally closed by a Spring-l'pressed plungerpsaid plunger being e longitudinally to expose the opening when the magazine is placed in, position on the implement. o,

A further object is to provide a sliding block or follower for feeding the nails to the drivin -head, said follower being movable lateral y to inoperative position through the opening in the magazine when it is desired to reiill or reload the magazine. p A still further objectA of the inventionis to generally improve this class of devlces, so as to add to their utility and durability as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being under-l stood that various changes in form, propor` tions, and minor details of construction may be resorted to within the scope of the append-` ed claims. I v In the accompanying'drawmgs, forming a part of this specification, Figure 1 1s a botv tom plan .view of a nailing implement con-l Fig. 6 is a transverse sectional view taken on the line 6 6 of Fig. 2, showing the spring-follower locked in inoperative osition. Fig. 7 is a detail sectional view s owing the cam for elevatingthe cut-off spring. Fig. 8 isa transverse sectional view taken on the line 8 8 of Fig. 2 with the spring. and magazine omitted.

p Similar numerals of reference indicate corresponding parts in all of the igures of the drawings.

' In its preferred embodiment the nailing implement forming the subject-matter of the present application comprises a driving-head 5, having aserrated driving-face 6 and a s litting-knife 7, secured thereto by a bo t 8. Seated in grooves or recesses formed in the opposite sides of the driving-head 5 and retained in position by the bolt 8. are the curved or deflected ends 9 of a pair of spaced parallel bars 10 11, which form a guide for the nails 12 in their passage to thedrivinghead. Extended laterally from the bar 1 1 is abracket 13, on which is pivotally mounted a hand-operated lever 14, one end of which is l provided with a nail-selecting device preferably in the form of a curved plate 15, havingaslot or recess 16 formed therein and provided with a slot 17 opening through one .side of the plate and communicating with the recess 16, as shown. The late 15 is mounted for lateral movement in alined slots `18,

formed in the curved ends of the bars 10 and 11, andis normally held in the position shown in Fig. 1 of thedrawings by m'eans of a coiled s ring 19, interposed between the bar 11 and tlie terminalthumb-piece 20 of the lever 1.4.

Detachably secured tothe nail-guide isa i magazine 21preferably tubular in form, as shown, and provided with alongitudinallydisposed slot 22, through which the points of the nails project in the nail guide. The magazine is slidably mounted incurved guides vor yokes (indicated at 23, 24, and 25, respecdeflected end of the nail-guide when the magazine is in place and serves to elevate the free end of the spring 28 .so as to permit the Secured to the opposite nails to be successively fed to :the drivinghead.

Formed in one wall ofthe magazine .2.1 is a recess or opening 30, :and slidably mounted in the adjacent end of the magazine is a spring-pressed plunger 31, adapted to `normally clo'se said opening and prevent the escape of nails when the magazine is detached, the opposite end of the magazine being normally closed by the spring 28, as best shown in'Fig. 4 of the drawings. By having the Amagazine formed-in the manner described .the latter may be filled with nails and convene iently transported from `place to place without danger lof the nails falling out at either end of the magazine.

Secured .to vthe plunger 31 isa rod 32, the free end of which yis extended laterally to form an enlarged head 33, adapted .to .engage .the yoke .23 when the magazine is positioned .on :the :implement-so as to expose the opening 30 for the purpose hereinafter described.

Secured to Ithe kbar 10 are spaced :brackets y34, yconnected by a rodor vbar 35, upon which isrslidably Amounted a spring-pressed follower or block 36. The block 36 is provided with :an zangular lextension 37, having a vterminal head 38, adapted 'to enter .the magazine 21 :and bearagainst the nails .12 for feeding the latter to the ydriving head, .there being a lcoiled spring 39 inter osed `between one of the brackets and the fo lower 36 .for yieldably supporting the block when in contact with the inails. The block 36 .is also provided with `a laterally-extending pin 40, `adapted to engage :a recess 41, formed in the bar 10, for `locking the follower in inoperative position, the lfollower being pivotally mounted on the `rod 35 to permit the plunger to be :swung :laterally to .inoperative position, as

best shown in Fig. -6 of the drawings.

The magazine is filled or loaded by elevating the free end .of the spring 28 and introducing-the nails in the :adjacent end yof the magazine, the :plunger serving to .prevent the escape ofthe 'nails through 4the yopposite .end of the magazine or through .the opening 30. .The ma azine -is then placed in position on .the imp ement Iby :threading the magazine through =the yokes 24 '25 and .moving the magazine longitudinally until .the free `end of the spring .28 yengages thecam-face 29, which elevates the spring and permits the nails to 'be delivered .to vthe driving-head. As the magazine is moved longitudinally of the nailguide the terminal head32 of the plungerlengages the yoke 23 and withdraws the plunger 31 'against the tension of the spring 42 from beneath 'the opening 3() and at the same time causes the :spring 26 to engage the recess 27 in said yoke, and thus lock the magazine in position ion the implement. The followerlock is then tilted laterally on the rod 35 and v.he head 38 of said block introduced through the opening 30 finto the magazine,

the-spring39 exertingra yieldable `pressure on the follower-block and serving to automatically feed the nails to the driving-head, as rwill be readily understood. When the nails reach the lower end of the feed-guide, they are stopped by the feed-plate until the lever 14 is depressed, when the point 43 of the blade passes between the first and second nail, which causes the first nail to follow the recess of the slot 17, the remaining nails being 'held by the edge 44 of the plate. As the feed-plate is moved transversely the nail is forced downwardly in the slot 17 until it is engaged and :held within the slot 16 and between the feed-plate and the side bar 10, as shown in Fig. 3. rllhe nail is then partially driven, .and when .thelatter is set the thumbe piece 20 is released, `which releases the head lof the nail, thus permitting the driving operation to lbe completed by striking the head of the nail with the driving-face 6.

In -order to release the magazine 21, -it is merely necessary to move the follower longitudinally within the magazine until the head registers `with the opening 30, when the block may .beswung downwardly, thus causing the pin or finger-piece 40 to enter the recess 41 .and lock the follower in operative position, the 'magazine being subsequently removed bydepressing the spring 26 and withdrawing the magazine from the guiding loops or yokes.

Attention `is called .to the fact .that the pin -40 not only serves las a means for locking the follower in inoperative position, but also serves as a finger-.piece by means of which the follower may be conveniently manipulated during the releasing and locking operations.

It will also be observed that by having the nails retained within the magazine in the manner described the implement may be .held at .any angle or inclination during vthe :driving operation, said implement being .provided with a depending handle 45 for convenience in manipulating the same.

The magazine may be loaded either by hand or connected in any suitable manner with a suitable loading or iillingldeviceofrany approved construction, and any number of .magazines may -be employed, so that when one of the magazines is emptied a full magazine may be `quickly placed in position on the implement.

Having thus .described the invention, what is claimed is- 1. In a lnailing implement, adriving-head, a nail-guide, `a magazine detachably secured to the nail-guide .and havin@ an opening formed in one wall thereof, a fo lower operating within the magazine, and means for successively presenting the nails to the drivinghead, said follower being moved laterally to inoperative Iposition through the opening in the magazine.
