Between the plates 16 l pivot at 27 a bell-crank lever 28, of which the shorter arm 29 engages the upper side of the lever 19, and its longer arm 30 extends up into the aperture 14, where it is pivoted at 31 to the rear end of the link or short rod 32, the lower or front end of which is pivoted at 33 to the short end of a scale-beam lever34, fulcrumed on the stud 35, and having its long end 36 pivoted at 37 to the rear end of the operatingrod 38, whose front end extends into the chamber or pocket 39, provided in the rear of the left side of the body of the hatchet, (see Fig. 4 and dotted lines in Fig. 2,) where it is pivoted at 40 to the lever or arm 4l, which has its upper end pivotally secured at 42 to the body7 of the hatchet and to its lower end pivoted at 43 the link 44, whose rear end is pivoted at 45 to the arm 46, which projects rearwardly from the left side of the centrallylocated round slide 47 while upon the right side of the web 5 extends rearwardly another arm 48 from the rear end of the right side of the slide 47, which will now be described. It consists of a cylindrical tube 49, having a slantingfront end 50, which is provided with a heavy bottom extending as far back as to 51 in Fig. 6. The out-er or front side of the bottom is curvedrearwardly in the middle, as indicated by shading in Fig. 6, where the slide is shown in central section, back to the cut-away line 52. rlhe front and solid portion of the slide is provided with a central slit 53', in which I pivot at 54 the nail-picker 55.

56 is a spring riveted at 57 to the in-ner side of the tube 49, and pressing upon the rear end 58 of the picker 55 tends at all times to hold its front end elevated as high up as it can come, which is shown in Fig. `6, where the normal position of the picker is shown in solid lines, and in dotted lines are shown as well the picker as the slide and the parts operatin g and operated by the slide when thrown forward tobring out a nail from the nail-box, presently to be described. The slot 53,in which the picker is located, extends rearwardly into Ithe lower side of the tube 49, so as to form an opening 58, through which passes' and is located a gooseneck-shaped rod 59, of which the front end is bifurcated or formed into a crutch-top-shaped jaw 60, and the rear end 61 extends through the tube and projects out of the rear end of it between the arms 46 and 48. (Best shown in Figs. 3, 5, and 6.) The rear end 61 of the bar 59 is pivoted at 62 to the lower and longest end of a traveling lever 63, which is pivotally secured at 64 to the rear end of the arm 48, and has its upper short and pointed end 65 engaging alternately either side of the pin 66, rigidly secured in the web 5, every' time the slide is moved either backward or forward b y the operatingmechanism already described and located mostly on the left side of the central web 5. When the push-bar 59 is pushed forward by the swinging motion of the lever 63, the upper curve 67 of the gooseneck touches up under the rear end 58 of the picker and tilts it into the position shown in dotted lines in Fig. 6. There is sufficient slack and spring in the parts to permit the pointed end 65 of the lever 63 to rise high enough to engage the pin 66, after the lever is tilted by the pin and has slid by it in either direction.

68 is a U-shaped spring, secured with one end to the screw 69 and with the other end engaging the scale-beam lever 34. lts function is to throw rearwardly and into new engagement the slide 47 and the entire mechanism so far described every time the thumblever 19 is permitted to release its lifting pressure up under the arm 29 of the bell-crank lever 28.

In the body 3 of the hatchet I provide the nail-box or elongated chamber 70, in which the nails are thrown or placed with their heads turned, some rearwardly and some forwardly, as indicated by the nails 71.

72 is a lid or door, hinged at 73 and kept closed by the thumb-latch 7 3X, pivotally secured at 74, held upon the edge of the door by the spring 7 5, and kept from swinging too far by the stop 76.

77 is a pressure-plate placed upon the top of the charge of nails and pressed down upon it by the pushing coil-spring 78, which, when the chamber is full of nails, is entirely compressed into the spring-barrel 79, provided for that purpose in the upper portion oi the hatchet.

Near the bottom of the chamber the side walls of the chamber are brought together to a slightly inwardly-curved V shape, as shown at 8O in Figs. 4 and 5, leaving between them the central opening 81, (best shown in Fig. 4,) which is only large enough to let one nail at a time drop down sidewise through it. The slot 81, it will be observed, is widened out at both ends to form a clearing 82 and 83 for the heads of the nails to pass through. Then a nail passes through this opening or gate 81, it is lodged against the upper side of the slide 47, as clearly shown in Fig. 6, where the nail 84 rests upon the slide in dotted lines, awaiting thevretraction of the latter, so it can get farther down.

The gate 81 is closed by a sliding plate or shutter 85, which is located and moves in a slot 86 in the left side of the hatchet. The inner edge 87 of this plate is beveled oft' at its upper side and cut away at its corners 88, as best shown in Fig. 9, to allow only the lowest one of the nails in the box to move down into position ready to slip down by the shutter when it is retracted, so as to open the gate 81. The motion of the shutter is caused by the engagement of its diagonal slots 89 with the pins 90, secured in the flattened top side 91 of a round sliding bar 92, which is inserted in a round hole 93, (see dotted lines in Fig. 2 and section in Fig. 5,) drilled from the fro hatchet and intersecting the slot 86.\

IOO

IIC

the shutter or pla-ie 85 is let down into the flattened top side 01 of the bar 02, as shown in Figs. 8 and 9.

94 is a screw-threaded plug screwed tightly into the front end of the hole 93. Between this plug and the front end of the slide 92 I place a pushing coil-spring 95, which actuates the bar 93 in a 'rearwardly direction, while the lever 41, touching against the rounded front end 06 of the bar 92, pushes it forward against the resistance of the spring every time it is swung forward by the operating mechanism.

In order to get the shutter S inserted in its place and dropped down upon the pegs 90, it is necessary to have the slot 86 about twice as'wide up and down as the thickness of the shutter-plate S5. l-lence after the shutter is put in there appears an idle space or opening above it, which I lill with an idle-plate 97, which is retained in the slot by the overhangin g head of the screw 9S, and prevented from moving too far in by its end projections 09, which are let into the side of the hatchet, as shown in Fig. 10, until the outer edge of the idle-plate comes flush with the outside of the hatche't and its inner edge comes iiush with the slanting portion of the wall of the nail-box close above the shutter.

As best shown in Figs. 7, G, and 5, there is in the rear side of the naihdriving hammer portion 2 provided a forwardly-curved groove 100, extending from the front end of the shutter 85 to the rear edge of the face 2 by which the nails are driven into the woodwork. This groove is provided near its middle or a little higher up with an offset forming a shoulder 101, below which is provided a pair of springdield jaws 102, which are inserted in suitable holes drilled from opposite sides of the hatchet. In each of said jaws is a loosely fitted plug with a cavity in its outer end in which is placed a pushing coil-spring 103, which acts between the bottom. of the cavity and the screw-threaded plug 104, which is screwed tightly into the 'hole outside the spring. The inner end of the hole is of a smaller size, so as to form a recess 105, which meeting the shoulder 100 of the sliding plug regulates its inward movement. The smaller portion of the holes are made square, and the inner and solid ends 107 of the sliding plugs passing therethrough are correspondingly made square, which prevents them from turning in the holes. The extreme inner ends of the sliding plugs are slanted olf at their upper side to form the inclines 10S, upon which the head of the nail 109 hangs, as shown in Fig. 7, where it will also be seen that the rear corners 110 of the jaws are slightly rounded, so as to permit nails to be moved sidewise in between the ends of the jaws.

Directly below and communicating with the cylindrical space or channel in which the main slide 47 moves is a slot 111, of which one side is shown in each of the views, Figs. 3 and 0. The gooseneclc part of the bar 59 moves in this slot, and it' a nail falls down into it its point and body will pass out through the slot, while its head will remain inside and cause the nail to assume the position shown by the nail 112 in Fig. 6, from which position it may be sent forward to the position of the nail 113 by the forward motion of the slide 47 and the crutch-shaped end 60 of the bar 59, which holds the nail in the manner shown in Fig. G, and in Fig. 5, where the nail 11S is shown in cross-section.

In further explanation of the operation it will be seen that when .the nails are lodged in the nail-box they are spring-pressed toward the gate 8l, and when the linger-lever is pressed up to the handle the bell-crank lever 28, rod' 32, scale beam or lever 34, rod 3S, and swinging arm 41 are set in such motion as to throw forward the link 44, and thereby the main slide 47. The sliding bar 92 is also pushed forward by the arm 41. The latter motion causes the shutter S5 to open and let one nail pass down upon the slide 47. By relaxing the pressure on the finger-lever the springs 21, 68, and 05 throw the entire mechanism back to its normal position, and as the sliding bar 92 moves rearward it causes the shutter 85 to shut the gate 81, so that no more nails can escape from the nail-box, and as the main slide 47 gets back to its limit the nail, located like 84 in Fig. 6, will (in the case of shingling and the like work) drop down into the position 112 and by the next pressing on the linger-lever be pushed forward by the front end of the slide 47 and the bifurcated end of the bar 50 and held in the position 113. The operator now gives one blow with the hatchet. The head of the nail meeting the shoulders 101 causes the nail to be driven into the woodwork about as far as it projects out of the hatchet, and when the hatchet is lifted preparatory to the next blow the nail sticking in the lumber causes the head of it to spread the jaws 102 and escape from them. The. next blow is then given by the driving-face 2 of the hatchet, and the work is done. The last-mentioned pressing on the linger-lever 20, it will be observed, not only moved the nail in between the jaws 102, but also caused another nail to come down between the shutter S5 and the slide 47, so that after the first nail is driven it takes but one pressing on the lever 20 to bring out each nail in position for use. In the case of lathing on walls or ceilings which requires the hatchet to be inverted, the nail will or may remain in the position 84, (shown in Fig. 6,) from which position. the slide 47 and picker 55 will simply push it endwise forward, causing the point of the nail to slide along the IOO IIO

groove 100 and down between the jaws 102 into the position 118. lf the nail is turned with its point toward the end of the main slide 47, (no matter whether the hate-het be inverted or not,) the pointed front end of the picker gets between the point of the nail and the bottom side of the shutter S5 and throws the point of the nail into the positions shown in Fig. 3, as 114 115, from which it is pushed in between the jaws 102 in about the same manner already above described about the nail 112 in Fig. 6.

It ywill be understood that it is the motion of the slide 47 and its arm 48 that causes the top end 65 of the lever G3 to move against the pin 66, and that the touch against the pin GG and then passing it causes the bar 59 to make a long and quick motion and then stand still while the other parts move. This enables the picker 55 and slide 47 to turn the nail through the various stages 114 115 (shown in Fig. 8) before the bifurcated jaw 60 comes forward to perform its function. If the said jaw GO came earlier, it would prevent the point of the nail from turning down through the slot 111.

It is obvious that the mechanism of my hatchet may be applied also in hammers for driving nails.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The nailing-hatchet having a suitable handle and in its body in front of the handle a nail-holding chamber accessible by means of a lid or door upon one side of it, said chamber having a substantially V-shaped bottom terminating in a slot or central gate adapted to let one nail at a time pass sidewise down through it, a spring-actuated pressure-plate pressing the charge of nails toward said gate, a shutter-plate traversing the gate-opening and closing it for each nail passing down; a slide or plunger moving in a channel in parallel direction with the nail-gate and being located centrally under and only about the thickness of a nail below the shutter of the gate, sogthat only one nail can come down at a time, the channel in which the slide moves having in its lower side a longitudinal slot of a width sufficient to let the body of a nail pass freely through it, but to retain the head of it in the channel, a lower nail gate or groove in the rear side of the hammer and driving-face of the hatchet, communicating with the said slot and channel so as to receive the nails either sidewise from the end of the slot or point foremost from the channel direct, if the hatchet be inverted; said groove in the rear of the hammer being provided with two spring-held, at the upper and adjacent corners, beveled jaws projecting toward each other from opposite sides of the groove, and a shoulder or recess near above the jaws, which are adapted to hold the nail with its head under the said shoulder and its point and body partly projecting below the drivingface of the hatchet, and to yieldingly release the nail when it is partly driven into the lumber, said slide having in its front end a pivoted spring-held tilting tooth or picker, by which to insure its getting hold of the nails and chasing them into the groove or lower gate, a pushing-bar having a crutch-top-shaped end straddling and pushing against the rear side of the nail, thereby helping to move it voted tothe handle of the hatchet and means for connecting it in operative contact with the said slide, pushing-bar, and shutter, substantially as shown and described and for the purpose specified.
