Application June 21, 1946, Serial No. 678,443

r12 claims.

This invention relates to stapling devices adapted to be held and operated in one hand to fasten sheets of material together by driving U- shaped staples or iastenersinto the sheets and clinching the ends of the leg portions oi the staples projecting from the sheets, and consisting of a magazine and arms carrying a driver and an anvil and pivoted on the magazine to have movements toward and away from the top and bottom ofthe magazine, respectively.

It is an object of the invention to adapt a stapling device of this character to be mounted in a carrying case resembling a fountain pen.

It is another object of the invention to provide a driver adjustable on its carrying arm to permit adjustment of said driver into and out of staple driving position and prevent the driving of staples when the stapling device is adjusted to be enclosed by a cap member of the carrying case.

It is another object of the invention to provide the magazine of the stapling device with inspection openings to permit the operator to see when the supply of staples needs to be replenished.

It is a further object of the invention to provide one end of the magazine with an annular portion adapted to releasably support pusher mechanism and adapt said magazine to be mounted in the carrying case.

` Other objects and advantages of the invention will hereinafter appear.

The stapling device forming the embodiment of the invention illustrated in the accompanying drawings comprises a magazine of channel shape in cross section having a bottom wall I4 and side walls I5 arranged with inwardly flanged longitudinal edges I6 joined at one end of the magazine by a transverse portion Il curved in a direction toward thebottom wall I4. The downwardlyI curved portion II conforms to the contour of the leg connecting portion of the staples s to facilitate the engagement of a clip or gang of detachably connected staples s, as shown in Figures 4 and 6. The inwardly extending flanges I6 engage the juncture between the connecting and leg portions of the staples and retain the ends of the leg portions of the staples against the bottom wall I4 of the magazine. The end of the magazine having the transverse portion I'I is provided with an annular member I8 having diametrically opposed bayonet slots I9 opening to one end and attached at the opposite end to the side walls I5 of the magazine by suitable means, such as solder or a weld, as indicated at 20 in Figures 1, 2 and 12, with diametrically opposed wall portions spaced from the bottom wall I4 and flanges I6 of the magazine, as shown in Figure 3. The opposite end of the magazine is arranged with a throat through which the leading staple of the clip of staples supported in the magazine is driven or discharged from the magazine. Said throat is formed by severing inwardly the end portion of the bottom wall M from the side walls I5 and bending said severed portion in an upwardly direction, as shown at 2l in Figures 3, 5 and 7, and forming notches 22 in the side walls I5 adjacent the ends thereof and said end portions-oi the side walls extending outwardly froirthe notches 22 having-thelongitudi#Y nal edges straight and not arranged with the flanges I5 and bent inwardly toward each other-'- and in spaced relation to the outer or front `face of the upwardly bent bottom portion 2 I, assilbv at 23.

The clip of staples s are moved and maintained under compression by pushefnlechaifisrnfcnle" prising a finger gripping or manipulating'mem-.- ber 24 having a circular enlarged head 25 slidably engaged inthe aniular lmember I8 of the 4 comprising an angle shaped member having one side portion 4I of substantially the same width as the distance between the side walls 35 and the other side portion 42 of a width substantially equal to the width of the throat 2I-23 or the distance between the side walls I5 of the magazine, whereby the portion 4I is slidable on the bottom wall of the arm 34 between the side walls 35A andthe portion 42 isi-.slidable-in thethroat zl-zs.

Sheets of material m are stapled by inserting and clamping said sheets between the bottom wall I4 and the anvil 5l and then actuating the arm 34 toward the top of the magazine to engage the driver portion 42 into the throat 2i--23 of the magazine. The actuation of the arms 39 and 53 toward the magazine |4-I6 is accomplished by the thumb and forenger of one hand of the user while the sheets are inserted between the anvil and magazine by the other hand.

The stapling device as described is of such size as to be readily carried in the pocket of the user and to facilitate the carrying of said device in the pocket of the user, there is provided, as shown in Figures 9 to 13, inclusive, a carrying case cornprising a tubular body or casing 51 having an exteriorly screw threaded enlarged portion 58 at one end and the Wall at the opposite end of increased thickness extending inwardly to form a bore portion of reduced diameter, as shown at 59 in Figure l2, for the mounting therein of the annular member I8 of the magazine I4-I6. The member I8 is retained in said reduced bore portion 59 by a set screw 60. The manipulating member 24 extends from the casing 51 and to enhance the appearance of the device, said member 24 is encased in a knob 6I of suitable material, such as plastic, which may be molded on the member 24 and secured thereto by lugs or ears 62 integral with and extending from the member 24, as shown in Figure 12. To facilitate the turning of the knob to engage the pins 26 with the bayonet slots I9 or to disengage the pins 26 from the bayonet slots i9, the knob 6| is arranged with knurling 63. The inner end of the knob abuts the outer end of the casing 51 when the pins 26 are engaged in the slots I9. The casing 51 is made of the same material and in the same or contrasting color as the knob 6I. The casing 51 is of a length substantially equal to the distancer between the outer end of the annular member I8 and the pivot pin 31, so that the end portions of the arms 34, 53 and the magazine carrying the driver 4|, 42, the anvil 5l and throat 2I--23, respectively, will extend from the screw threaded end 58 of the casing 51 to permit the stapling of the sheets m Without interference. When the stapling device is not in use the stapling portions of said device extending from the screw threaded end 58 of the casing 51 are encased in a cap member 64 having internal screw threads 65 at the open end to releasably mount the cap member on the screw threaded portion 58 of the casing 51 and a pocket clip 66 mounted thereon adjacent to the closed end. The cap member 64 is also made of the same material and in the same or contrasting color as the casing 51 and knob 5 l. When the carrying case 51-66 is fully assembled, it resembles a fountain pen in appearance. When it is desired to encase the extending portions of the arms 34, 53 and magazine I4-l6 with the cap member 64-66, the driver 4l, 42 is adjusted to engage the detent 48 in the indentation 46 to position the driver portion 42 in front of the throat 2 I-23, and the arms 34 and 53 are juxtaposed to the magazine I4-I 6 to permit sliding of the cap member over said extending portions of the arms and magazine and engagement of the screw threaded portion 65 with the screw threaded portion 58. With the cap member 64 engaged on the casing 51, the arms 34 and 53 will assume the broken line positions shown in Figure 12 under the iniiuence of the springs 39- and 55,1

respectively.
