Y Our invention has forits object to provide an improved hammer or hatchetof the type having in its handle a nail magazine and suitable mechanism for automatically removing the nails from thel magazine and delivering the same into a position to be set by a blow delivered by the hammer or hatchet.

To the above end, generally stated, the invention consists of the novel devices and combination of devices hereinafter described and defined in the claims.

ln` the accompanying drawings, `which illustrate the invention, like charactersindicate like parts throughout ythe several views.

Serial No. 16,602.V

of said forgings a hatchet blade 3. Within the head 1 is formed a handle receiving eye at, and a feed chamber This eye a does not extendcompletely through the head 1, and the feed chamber 5 extends in front thereof rand topoints both above and below Said eye. The front of the feed chamber 5 is open below theaxis of the eye et.

Mounted within the eye l is a handle rigidly secured/to the head 1 by rivets 7. In the outer end portion of this handle 6 is formed a nail magazine 8 and, in the'intermediate portion thereof, above its horizontal center, is a nail arighting ychamber 9, having communication with said magazine. The topofthe arighting chamber 9 is open `and normally closed by a saddle plate10which embraces the sides of the handle 6 and is detachably secured thereto Vby screws 11. Obviously, access may be had to the arightingchamber 9 by removing the saddle 10.

The ,outer open end of the magazineS is normallv closedby a gravity actuated gate 12, hinged to the top of said magazine, ar.-

`ranged to swing inward, and of alength greater than the height `of. said magazine, which f prevents the gate 12 from swinging outward through the open end of the magazine. yBy thus mounting the gate 12, the

same', Vwhen closed, stands in an oblique polsition .(see Fig. 3), andthe nails Z, within the'magazine 8, hold the door closed. f l Formed in the handle 6, below the arigh ing chamber 9, is a longitudinally extended guide channel 13 `which extends the full length of said chamber and into the feed chamber 5. Mounted in the guide-slot `1d, near the upper surface thereof, is a pair` of horizontally` spaced guide rails 14, as shown, made'from a single piece of wire bent upon itself. The'rear or connected endsof the rails 1a rest upon a ledge 15 formed in the handle 6 at the entrance of the magazine 8` tothearighting chamber 9. At their forward or free endsthe rails 14 are curved downwardly and rest on the bottom ofthe eye 4L at ay point where the same enters the feed chamber 5. Mounted in the bottom of the arighting chamber 9 is a'Inetal plate 16 having a lon` gitudinally extended nail arighting slot 17, which directly overlies the rails 14. The ends of this plate 16 are bent downward to afford anges 18 and 19, which rest on the rails 14 and support the plate 16 thereabove.Y

Alrivet 20, passed throughy the ledge 15, between the rails 14, and through the plate'16, securely holds said plate in position, and which plate, in turn, by its flange 18, holds the rear ends of the rails 14 onto the ledge 15. The rivet 20 and ledge 15 also Ahold the rails 14 against endwise movement in either direction. The forwardend of the plate `16 is held in position with its flange 19, which is notched toy afford a clearance passage be.- tween the rails 14, resting directly on said rails, by a flange 21 formed with the saddle 10, and extending through the arighting chamber 9. I

The width of the slot r17 is sufficient to Jermit the bodies of the nails to pass therebetweenV during the arighting thereof, but not their heads7 which rest on the plate 16 with their bodies hanging freely between the rails 14 and through the guide slot-13. The slot 17, at yseveral Vlongitudinally Y spaced points, (as shownl in'Figs. 2 and 3) is widened to afford nail escape passages`22 Vthrough which the heads ofthe nails, supported on the plateV 16, may drop. 'The nails, in dropping through the passages 22, are

again intercepted by their heads coming in vcontact with the underlying rails 14, ony

which railsl the nails are supported for movement through the slot 13 'to the feed chamber 5. The purpose of the plate 16 and escape passages 22 is to prevent the nails from clogging between the rails 14 as they are arighted. j

During the travel of the nails on the rails 14 toward the feed chamber, they are successively engaged by a pair of escape dogs 23, as shown in the form of upwardly and lforwardly inclined pins, mounted in seats 24in the handle 6, forward ofthe arighting chamber 9 and loosely resting one on yeach of the rails 14. These escape dogs 23 will lift to permit the nails to pass thereunder during their forward travel, but will not let them pass in a return movement. After the nails have passed the escapement dogs 23, they are intercepted by an escapement which' will presently be described.

Mounted on the front face of the head 1, and closing the feed chamber 5, is a combined nail starter and'escapement actuator in the form of a: plate 25, pivotally mounted for oscillatory movement Vin a vertical plane. Asl'shown, the pivotal support for the plate 25 is in the form of a stud 26 on the head 1 andwhich projects through a perforation 27 in said. plate. This pivotal connection for the plate 25 is located at one side of the vertical'center of said plate and at substantially the vertical center thereof. A flatv spring 28, pivoted at 29 lto theV head 1 of the hatchet, above the plate 25, bears against said plate audits lower endv is bifurcated to receive a pin 30 on said plate above the pivot 26 for Yoscillatory movement with the plate 25.

This spring 28 yieldingly and frictionally holds the plate 25 in either of its extremey previously referred to,

prongs ofthe escapement V31 embrace the V curved front ends of the rails 14, and their free ends are bent laterally inward to afford 4a pair of points 32 and 33. These points slightly overlap kone another, and the point 32 is spaced in advance of the point 33 to permit? the body of a nail to pass therebetweenu The 'escapement points 32-33 eX- tend belowT the rails -14 and normally the point 32 projects across the pathy of movementV of the nails between therails 14., During the ocillatory movements of the plate 25, the escapement is ac tuated'to separate the foremost nail from the main column in the well known manner. d

- Each nail, after having passed the escapement pointsk 32.-3'3, continues its forward movement over the rails 14 until theV same comes in contact with an oblique stop 34 formed by slotting the 'head 1 below the eye 4 to aord a continuation ofthe slot 13. Undervthe lifting movement of the hatchet to deliver a blow, the nail, resting on the stop 34, is thrown by centrifugal force to the top of the feed chamber 5. 7 On striking the top of the feed chamber 5,the nail drops,

under the action ofl gravity, into a contracted discharge passage' 35 formed in the head 1 below the feed chamber 5. The rear wall of the feed chamber 5, above the guide slot 13, is formed oblique to. afford a defiecting surface 36, with which the nailsengage,

when thrown from the stop 34, to deflect the same to the front of the feed chamber f At the junction of the side walls of the feed chamber 5 with the discharge passage 35, are

deflecting surfaces 37, with which thepoints 'of the nails engage to cause the same to enter the said discharge passage. The discharge passage 35 is wide enough to receive the bodies of the nails, but not their heads, so that the nails entering said discharge passage are supported therein by the engagement of their heads with the deflecting surfaces 37. At the back of the discharge passage 35 is a defiecting surface 38 which causes the nails, upon entering said discharge passage, to,` travel .forward into a position, as shown in Fig. 3,v with their points projecting below thestriking surface of the hatchet and their heads directly underlying the striking surface 39 of the combined nail starterandfescapement actuator.y yThe nails, in assuming the position just described, are prevented from passing entirely out of the discharge passage 35 by 4a depending extension i0 on the plate 25, whichnormally eX- tends obliquely across they discharge passage 35,as best'shown irl-Fig. e a

A depending stop lug all onthe striking face 39 of the plate 25-engages theheadl to limit the oscillatory movement .of the plate 25m one direction, andthe plateextension engages one ofthe sidewalls of the discharge passage to limittheoscillatory movement of said plate inthe other direction. In the sides of the head l lare formed sight openings 42 located substantially opposite the points' 32-33 of the escapement. A 'discharge opening 43 is formed inthe back of the head l, above the deflecting surface 38, opens into the feed chamber 5, and through which. opening surplus nails aredischarged to prevent clogging of the discharge passage 35. f ris shown, the plate E35 and its extension a() are mounted in a recess formed in the front of the head l and the overlying shoulder of said head affords `an abutment 44 for the plate 25 to resist driving strainsin partly driving nails and thereby relieves the strain on the pivot stud 26. Obviously, by bending the spring 28 out of engagement vwith the pin 30, said spring may be turned into ya position, as shown in Fig. 5, and the plate 25, together with the escapement 31, `removed frein working positions. n g

Operation: rlhe operation of the improved nail magazine hammerfmayy be brieflyv described as follows The magazine 8 isiilled with nails by holding 4the handle y'ofy the hatchet ina-n upright position with the head downward. ln this position of the handle,`the gate l2 swings open under the action of gravity, allowing the'nails to be poured into the magazine 8 and into the arighting chamber 9. rlhen by turning the handle 6 into a substantially horizontal position and giving the same a slight shake, which causes a number of the nails to dropfinto'the arighting slots 17 and 13, where certain of the 'nails will work through the escape passages 22 and drop onto the guide rails 14; From thence the nails will work along the guide rails 14;, under the escapement dog 23,'unti`l intercepted by the escapement finger rlhe operator ,then oscillates the `plate E25, by means of his fingers, to actuate the escapement, releases the first nail from the ymain column and sets the plate 25 in a position shown in Fig. 4l with' the extension 4.-() cutting oil? the discharge passage. The nail'just released by the escapement, will continuer its travel, under the action ofgravity, alongthe curved front ends of the rails 14, and bedeposited thereby onto oblique stops "Then by giving the hatchet aslight upward swing,

said nail'will be thrown by centrifugal force from the stop into the feed chamber 5 and drop, under the actionof gravity, into the discharge passage 35, where it will be held by the extension l0 with its point projecting 'v70 below the striking surface of the head yl and ,with its head underlying the striking surface 39 of the nail starter. rlhe hatchet is now ready for use. The first blow of the hatchet will bring the striking surface 39 of the nail starter into contact with the nail in the discharge passage 85, thereby partly driving the same. rlhe action of this blow on the plate 25 will oscillate the same on'its pivot 26, thereby opening the discharge passage 35 and actuating the escapement 3l to release a second'nail. In the lifting of the hatchet lfor the second blow, the initial movement is toward the operator, to free the hatchet from the partly driven'nail through the open discharge passage rEhis second upward stroke of the hatchet will throw the second nail from thestop 34, as previously described, kinto the feed chamber 5r As the second blow is delivered by the hatchetto drivexthe partly driven nail home, the force thereof will cause the plate 25 to swin'lr on its off-set pivot 26 into its normal position', as shown in Fig. 4, therebycutting offr the escape of the second nail in the discharge, passage y andfaetuating the escapement ,31 to cause the third nail of the main: column to moveinto a position between the points 32-33 .where the saine will be releasedfby the escapement under the action of the blow delivered to 'partly drive the second nail.

From the foregoing description, it is evidentlthat only twoblows of the hammer are required to drive a nail; the first blow to partly drive the same, and they second blow to drive the nail home. Before all ofthe nails in the magazine are used, others should be added,-so that thenailsr arge fed fromi the magazineto the nail starter automatically and without interruption. 4 '110 By reference to Fig. el, it is important to note that when the plate 25 is in a releasing position, the lug ll will move back of a pro- ]ecting lip 45 to prevent the plate 25 from being pulled from the stud 26, in case the eX- tensionshould catch on a partly driven nail as the hammer is withdrawn therefrom.
