6 Claims.
This invention relates to handmachines designed primarily for driving nails, an object of` the invention being to provide a device of this character embodying a magazine in which the nails are held, means being provided for ala vancing a nail to a position to be driven, with each operation of the handle to operater the hammer and driving pin.
An important object of the invention is to provide a device of this character wherein the nails held within the magazine, will be advanced one at a ti-me, with each operation o the handle and hammer of the machine.
Another object of the invention is the provision of a nail feeding means which will insure against more than onenail being moved to a position directly under the hammer, at each operation of the handle, thereby eliminating any possibility of the nails'jamming, to render the operation of the machine diicult.
With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be nia-de within the scope of what is claimed, without departing from the spirit o the invention.
Referring to the drawings:

Figure 7 is a fragmental perspective view of the cooperating feed bars of the magazine.
Figure S is a fragmental elevational View part ly yin section, illustrating the position of the hammer, prior to its release.
Referring to the drawings in detail, the body 'portion of the device is indicated` generally bf: the reference character 5 and is of channel con struction, thebody portion comprising side plates 6 and a bottom l. Rising from one end of the body portion, and formed integral therewith, i'; a hammer barrel 8`which is circular in cross section, the upper end thereof being closed by means of the removable cap 9.
Asshown, the hammer which is indicated at it, is of a size and shape to fit within the hammer barrel 8 for free sliding movement. A coiled spring indicated at l I is disposed within the hammer barrel and rests on the upper endy of the hammer Iii, to normally urge the hammer downwardly. Secured to the hammer i9, is a driving'pin l2 which is so located that it will fall directly over anail which is fed through the bod-y portion, andV which is to -be driven by the hammer.
A recess indicated at i3 is formed in the outer surface ofthe hammer, and the recess is so constructed that a sharp edge is provided, to be cngaged by the pivoted arm it, which is provided with a notch to receive the sharp edge. The arm i4 is pivotally connected at the forward end of the bar l5 and a spring member it is provided on the bar, one end of the spring member being connected with the arm ifi, while the opposite vend thereof bears against the bar l5, to normally urge the arm I4 towards the-hammer iii. The bar iii is pivotally connected with the stationary links l1 which are secured to the side plates 24 of the body portion, by means of vthe pin ii. The forward end of the leverl i3 is pivotally connected with the stationary links il and has its rear end constructed to provide a handle il). A bell crank lever indicated at 29 has pivotal connection with the lever i3, at a point slightly in advance of the vertical line drawn intermediate the ends of the'lever.
A spring indicated at 2i has one of its ends bearing against the bell crank lever 20, the oppo# site end thereof bearing-against the lever it, norm aily urging the lever i t and particulariy the handle end thereof, upwardly. The bar lia connects with the heil cranklever at 'in order that the arm l move longitud .,aliy cf the hammer barrel, a longitudinal slot formed in the hammer barrel.
The vbody portion also includes side plates 24 spaced apart, adjacent to the front end of the body portion. Extending inwardly from the inner .surfaces of the side plates 24, are pairs of spaced vertical ribs 25, between which the vertically movable cam 26 operates, the cam 28 being pivotally connected to the lower end of the bell crank lever 20, at 21. The cam 26 embodies spaced leg members, the lower ends of which are beveled as at 28.
The magazine in which the nails are contained and fed to the hammer, is of exceptional importance in the operation of the device, since the magazine insures against more than one nail being fed t'o the driving pin, at each operation of the lever I8. l The magazine is also constructed to insure against the nails jamming to prevent the operation of the machine. The magazine comprises a removable main section embodying spaced plates 29 thatr are connected at their outer ends, by means of the end member 30,
formed integral therewith. These side plates 29 are so arranged that they will slide between the side plates 6 of the body portion ofsthe'r device, from the open end of the body portion and be held in place by frictional contact with said side plates, as clearly shown by Fig. 4 of the drawings. Upper and lower inwardly extended flanges 3| are formed along the longitudinal edges of the side plates 29, and extend inwardly therefrom, the flanges providing guides for the movable bars 32 and 33 of the magazine. Mounted between the forward ends of the side plates 6, is a spacing block 34, which is held in position by means of the screws 35, the spacing block being formed with cutout portions, providing a web 36 that has its inner edge curved to conform to the curvature of the driving pin I2, and nails which may pass from the magazine, to the curved surface of the web. The spaces between the web 36 and side edges of the block 34, provide guides for the forward ends of the bars 32 and 33, as clearly shown by Figures 4 and of the drawings, Extending inwardly from the bar 32, at a point adjacent to the rear end thereof, is a rib 31 which is adapted to fit Within the recess 38 formed in the inner surface of the bar 33, the recess 39 being appreciably wider than the rib 31, so that the bar 33 may slide with respect to the bar 32. Formed in the bars 32 and 33, and disposed at points adjacent to the centers of the bars, are recesses 39, which recesses provide upwardly facing inclined surfaces 46 and 4I and downwardly facing inclined surfaces 42 and 43. These recesses, are disposed directly under the vertically movable cam memsurfaces 28 thereof will engage the inclined suri faces 40 and 4|, moving the bars 32 and 33 forwardly and since the inclined surface 40 is disposed above the inclined surface 4I, the cam surface 40 will be engaged prior tothe engagement of the member 26 with the cam surface 4I, moving the bar 33 in advance of the bar 32. Upon upward movement of the cam 26, the beveled surfaces 44 thereof, will move over the cam surfaces 43 and 42 sliding the bars rearwardly, or reversing the movement of the bars. Disposed on the adjacent inner surfaces of the bars 32 and 33, and arranged longitudinally thereof, are spaced ribs 44', the ribs of one bar being arranged so that they will move between the ribs of the adjacent bar. The ribs 44' are formed with teeth, which are so constructed that they provide shoulders 45 and inclined surfaces 45, leading to the shoulders. The spaces formed by the teeth, provide compartments for the nails which are driven with the machine, and which in the present showing are indicated at A. Wide spring members 41 are disposed in recesses formed in the outer surface of the bar 33. The free ends of the spring members bearing against the side plate 29, adjacent thereto. These spring members 41 tend to urge the bar 33, towards the bar 32, gripping the nails within their compartments.
The handle is indicated by the reference character 48 and rises from one end of the body portion 5. The forward end of thel handle is secured in position by the bolts 49 which extend vthrough the handle and side Iplates 24.
When using the device, the magazine is rev'moved from the body portion and the nails to be driven are positioned in the various compartvments of the magazine, and the magazine is repositioned. ,The device is held in the hand of the user by gripping the handles 41 and I9. As pressure is applied to the handle portion I9 of thelever I8, the hammer I 0 is elevated within the hammer barrel, against the tension of the coiled spring I I. When the hammer has reached the limit of its upward movement, the coiled spring is tensioned, and uponfurther pressure applied to the handle portion I9 of the lever I8, the pivoted arm I4 snaps away from the hammer I9. It will of course be understood that the driving lpin I2 is now directly over a nail, and that the pressure of the spring II acts to urge the hammer and driving pin downwardly, setting the nail.
With the downward movement of the lever I 8 caused by pressure directed to the handle I9, the beveled edges of the vertical movable cam 26, move over the inclined surfaces 40, moving the bar 33 forwardly, and since the nails rest against the shoulders of the compartments of the bar 33, the nails will be advanced over the inclined surfaces of the compartments, to take the positions shown by Figure 5 of the drawings. Upon further movement of the lever, the bevel surface of the cam 26, at the opposite side of the cam, engages the inclined surface 4I of the bar 32, moving both the bars 32 and 33 of the magazine forwardly and causing the nails to be advanced in the compartments, the nail nearest to the forward end of the portion being deposited directly under the driving pin I2 to be set by the hammer and driving pin.
From the foregoing it will be seen that upon repeated movement of the lever |8 as described the nails will be advanced and driven by the hammer, until the supply of nails has become exhausted.
In view of the foregoing detail description, it is thought that further disclosure as to the operation of the device is unnecessary.
Having thus described the invention, what is claimed is:
