7 Claims. (Cl. 1-3.05)

The present invention relates to a pocket stapling device, and has for an object to provide a stapling device of this character in which staples of normal size, such as employed in standard size stapling devices may be used, as distinguished from prior pocket stapling devices which have been restricted, because of their limited size, to the use of small size staples.

A further object is to provide a pocket stapling device comprising cover, body and base parts hinged together so that in their operative stapling position the cover and base parts may be swung in relation to the body part to afiect the stapling operation, and which in their inoperative position are folded together in closed flat relation so as to provide a compact flat structure which may be easily slipped into a vest or change pocket. The flat form of the device in its closed position also makes it especially desirable as an accessory for carrying in a briefcase. While it is the purpose of the invention to provide a pocket stapling device of relatively fiat form so that it may be conveniently carried in the pocket, it is also desired to make such device of suflicient width and length to enable it to be firmly held in the hand and also to provide sufficiently large pressure surfaces for operation by the fingers and thumb, without excessive eifort or discomfort, to efiectively drive and clinch the staples in the operation of stapling together papers or other suitable material. In carrying out this purpose, longitudinal spaces are provided at each side of the centrally disposed staple carry ing rail forming part of the structure, and it is a further object of the invention to design and utilize these spaces to provide compartments for the storage of additional staple strips. In the disclosed embodiments of the invention four staple strips may be carried, in addition to the staple strip mounted upon the staple carrying rail, and, as each such strip as at present commercially produced consists of approximately 100 staples it will be seen that the stapling device may be provided with as many as 500 staples, giving to the relatively small compact pocket stapling device of the invention substantially greater staple carrying capacity than the usual desk or plier type stapling device which only carries a single staple strip. It is also an object of the invention to provide a pocket stapling device which may be efiectually used as a desk stapler, as well as a tacker, the wide flat form of its base part providing a firm non-tilting support upon the desk in the one case, and the wide flat form of its body part providing a similar firm non-tilting material engaging surface in the other case.

With the above and other objects in view, embodiments of the invention are shown in the accompanying drawings, and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawing, the pocket stapling device, according to the illustrated exemplary embodiment of the invention, comprises three main parts, namely an intermediate staple carrying body part 10, a staple driver carrying cover part Ill, and an anvil carrying base part 12, these parts being hinged together at their rearward ends, as will presently more fully appear.

The intermediate body part 10 is of substantially rectangular tray form and consists of a base wall 13, and an upstanding peripheral rim wall 14, the side portions of which are inwardly offset at their rearward ends, as at 1515, to receive the hinging means of the cover and base parts, as will presently more fully appear. A longitudinal staple carrying rail 16 of inverted U-shape in cross-section is disposed centrally upon the base wall 13, being provided at spaced points along its lower edges with downwardly projecting lugs 17 which are secured by staking in slots 18 provided in the base wall. A helical expansion spring 19 is assembled within the rail in compressed relation so that its rearward end bears upon the rearward portion of the rim wall 14, its forward end being adapted, as will presently more fully appear, to propel a push shoe forwardly. The upper wall of the rail is provided with a longitudinal slot 20 for receiving a connecting part of the push shoe.

The forward end of the staple carrying rail is spaced from the forward portion of the rim wall 14 to provide a space within which is engaged a staple guide member 21, comprising a vertical forward wall portion 22 of rectangular form, secured by welding or the like to the inner surface of the front portion of the rim wall 14 and projecting substantially above it, rearwardly extending side wall portions 23-23, disposed in spaced relation at each side of the forward end portion of the staple carrying rail to provide guide spaces at each side thereof for the legs of the staple strip S, and flange portions 2424, bent inwardly from the upper edges of the side wall portions and spaced above the upper side of the staple carrying rail to provide a guide space for the top or bridge portion of the staple strip. The forward edges of the flange portions are spaced from the inner surface of the forward wall 22 to provide a passage for the staple driver, as will presently more fully appear. The spacing of the forward end of the staple rail from the inner surface of the forward wall 22 also provides a space for the staple driver to move in driving the staple, the dimension of the space being such as to receive the foremost staple of the staple strip. The base wall 13 is provided with a U- shaped slot 25, the transverse intermediate portion of which is in line with the staple driving space and constitutes the ejection opening for the staple, and the rearwardly extending side leg portions of which are disposed at each side of the forward end of the staple rail and constitute clearance spaces to prevent jamming of the staples within the device.

The staple push shoe 26 is of inverted U-shape in cross section and slidably fits upon the rail with its forward edge engaged behind the staple strip. It comprises an upper wall 27 and side walls 2828, the upper wall having an upstanding lug 29 bent therefrom to provide a manipulating handle for convenient retraction of the push shoe. The upper wall is also provided with a downwardly extending lug 30, centrally disposed and inwardly offset from the forward edge, and which is adapted to freely engage within the slot 29 of the rail, this lug being provided with rearwardly extending ears 31-31 which are adapted to interlockingly engage within the forward end of the spring 19. This engagement is affected by first holding the forward end of the spring retracted with a suitable tool inserted through the slot 20, thereupon placing the push shoe upon the rail forwardly of the forward end of the spring with the lug 36 in the slot 20 and the ears 31 in position to be engaged by the spring as the latter is released. As the diameter of the spring is greater than the width of the slot 20 the push shoe is thus effectually locked in place.

As will be observed from Fig. 9, the inward offsetting of the lug 30 from the forward edge of the push shoe corresponds to the spacing of the forward end of the slot 20 from the forward end of the staple carrying rail, so that in the extreme forward position of the push shoe, with the lug 30 engaging the forward edge of the slot 20, the forward edge of the push shoe is flush with the forward end of the rail. Thus, the push shoe will effectually drive the last staple of the strip into the staple driving passage, but the push shoe itself will not enter the passage to interfere with the engagement therein of the staple driver.

In spaced relation at each side of the staple rail there are provided upwardly projecting lugs 32 which define the inner sides of staple strip receiving compartments at each side of the staple rail, the outer sides of these compartments being defined by inwardly projecting ribs 33 pressed into the side portions of the rim wall 14. The spacing of the lugs 32 from the ribs is suflicient to allow a pair of nested staple strips to be fitted therebetween, as shown in Fig. 3, the lugs preventing interference of these staple strips with the staple strip and the push shoe operating upon the rail, and the ribs preventing their interference with detent means cooperating between the body part It) and cover part 11, as will presently more fully appear.

The cover part 11 is of substantially rectangular tray form, and consists of a top wall 34 and a downwardly extending peripheral rim wall 35, the side portions of which are inwardly offset at their rearward ends, as at 36--36, to receive the hinging means of the base part, the inwardly oflset portions being provided with downwardly extending ears 37-37 which are adapted to engage within the recesses 15-15 of the body part 10 where they are hingedly connected, as will presently more fully appear. The cover part conforms in outline shape to the body part, so that in the closed position of the cover part the edges of its rim wall 35 abut the edges of the rim wall 14 of the body part. Within the forward end of the cover part a staple driver strip 38 having a securing flange 39 bent at right angle thereto is secured by welding or the like to the underside of the top wall 34, this strip being positioned so that in the open operative position of the cover, as shown in Figs. 2 and 9, its lower end engages the inner side of the forward wall portion 22 of the staple guide member 21 slightly above the staple disposed in the staple driving passage. Upon pressing the cover downwardly the staple driver strip enters the staple driving passage and drives the staple downwardly therein and through the ejection slot 25 into clinching engagement with the anvil, as will presently more fully appear.

A spring member 40 is carried within the cover part.

and comprises an intermediate transverse portion 41 secured by welding or other suitable means to the underside of the top wall 34 of the cover part, a downwardly otfset forwardly extending leaf spring portion 42 engaged at its forward end with the flange portions 24 of the staple guide member 21, and a downwardly offset rearwardly extending leaf spring portion 43 adapted to engage the upper side of the nested staple strips disposed in the compartments at each side of the staple carrying rail. The set of the leaf spring portion 42 is such that it normally exerts pressure to raise the cover part with respect to the body part so that following each stapling operation the cover part moves automatically to its operative open position. The spring is provided with a centrally disposed longitudinal slot 44 providing a clearance space in which the handle portion 29 of the push shoe moves. At the ends of the transverse portion 41 there are provided downwardly extending detent spring portions 4545, each having an arcuate slot 46 substantially concentric to the hinging axis of the cover part. These detent spring portions are adapted to interlockingly engage with rounded detent studs 47--47 secured upon the inner sides of the side wall portions of the body part, to normally limit the opening movement of the cover part under the force of the leaf spring portion 42 to the staple driving position, as shown in Fig. 9. They can be disengaged from the studs 47 by manually exerting sufficient opening pressure upon the cover to force the ends of the springs to yield inwardly about the rounded form of the studs, reengagement being accomplished in the same way by pressing the cover closed. This action allows the cover part to be moved to an open position, as shown in Fig. 3, to permit access to the staple carrying rail and the stored staple strips within the body part for the purpose of placing a staple strip upon the rail. In the closed position of the cover part the

spring portions

42 and 43 press upon the nested staple strips in the storage compartments to hold them against movement within the body part. In the open position the spring portion 43 continues to perform this function.

The base part 12 is of substantially rectangular tray form and conforms in outline shape to the body and cover parts. It comprises a base wall 48 and an upstanding peripheral rim wall 49 provided at the rearward ends of its side portions with upwardly extending hinging ears 50-50 which are adapted to engage within the recesses 15-15 of the body part 10 and 3636 of the cover part 11. These ears are each provided with a bearing hole 51 adapted to register. with a bearing hole 52 provided i eae o th ear 5. of the n ver pa t .11 an which n ur registers ith a hear-ins he e pro id d in ach of e se po tion .15 o the body par 10, t s registering b ari le a he e pec i des be n engaged by riveted pivot studs 54-54 to thus hingedly nect the cover and b e Pa ts o he body Part. h length of the cars 50 and the position of the pivot axis are such that the cover part may, if desired, be swung through 80 to a a a i y ex en i open posit as shown in Fig. 4, to permit the device to be used as a tacker, in which case the body part is engaged directly upon the material to be stapled and the staple is driven therein without clinching of the staple legs.

A t pl clinching M 55 havin p e leg clinching grooves 56-56 is secured by welding or the like within the forward end of the base part in line with the staple driving passage, so that a. staple when driven through material M, as shown in Fig. 9, has its legs clinched be- Heath e m e ial n upwar y e -rv d l af sp n s u e by W ld n er he l k wi hin the rearward end o t here P nd b ars even t e undersi e of the bo y Part. thus n ma y tending to Pr s the ase part in downwardly spaced relation to the body part for convenience in inserting ma a twee th jaws thus formed- The upper edges 53 of the side portions of the rim wall are inclined downwardly from their forward ends, S that in e n m ope p i en, as seen in ig- 9, h lower iaw of the material receiving space is substantially parallel to the underside of the body part forming the upper jaw.

In order to retain the cover and base parts in inoperative closed relation to the body part a clasp is provided consisting of a flap member 59 having a hinge curl 60 at its pp end r hlv en a ed upon a pin 61 sup- P r e at ts s in pe tur s h s 62 pi rce a d bent om t ward r m e l pe tien f the co par i p b n Provided n ar its l wer end with an aperr e 63 p d to e en a d by a lat pin .64 secured p n e forward rim wa l port on of he base Part 12. In the closed position, as seen in Fig. 8, the clasp is held n op r i e P s tio by he spring en i n e up by the p ings 40 a d 7 t be ng nly neeesssa y in Order to disengage e c a p o press it f rwa dly with sufiicient force to overcome this spring pressure. Thereupon, the cover and base parts will open to their operative positions, as seen in Fig. 9, the open position of the cover part being limited by the detent springs 45. In this open position the flap is swung into engagement with the upper side of the cover part to remove it from interference with the stapling operation.

In operation, the stapling device may either be supported upon a flat surface and operated by exerting downward pressure upon the cover, or by holding in the hand and compressing the fingers and thumb upon the base and cover parts.

The stapling device may also be efifis lually used as a desk type stapler, in which case the relatively wide flat base 12 provides a firm non-tilting support for resting upon the desk top. In case of the stapling device being used as a tacker the cover 12 is swung to the rearwardly extending position, as shown in Fig. 4, and the undersurface of the body 19 provides a relatively wide flat surface for firm non-tilting contact with the material being tacked.

In Figs. 11 to 15 I have illustrated a modified form of the invention wherein the guide member 21 as employed in the first embodiment is dispensed with, a substantially similarly functioning structure being provided by inwardly offsetting the forward end of the peripheral wall 14 of the body part 12 and extending the same upwardly to provide a vertical guide 22a for engagement with the staple driver 38, side wall portions 23a23a being blanked and bent upwardly from the base wall 13, the upper edges of these side wall portions being slightly above the upper surface of the staple strip S upon the rail 16. In order to provide an upper limit for he orward end of the staple strip,

n Pla e of th a e po tio 24+. a emp oyed in h guide member 21 of the first embodiment, the forward end of the spring for exerting opening pressure Upon the cover part is slideably engaged with the upper edges of the side wall portions 2341. A modified form of spring 40a is employed, consisting of an intermediate transverse portion 41a secured to the top wall 34 of the cover part 11, at each end of which there is provided a slotted detent spring portion 45. A centrally disposed leaf spring portion 42a extends forwardly from the portion 41a and is provided at its forward end with a flat widened portion 65 for sliding engagement with the top edges of the side wall portions 230. Instead of the handle portion 29 provided upon the push shoe 26 the push shoe is modified to provide handle portions 29:: at each side disposed outwardly of the edges of the spring portion 42a.

Modified holding means are provided for the staple strips S stored within the compartments at each side of the staple rail, consisting of cushion holding strips 6666 of sponge rubber or the like secured by cementing to the underside of the top wall 34 of the cover part, these cushion strips being engaged under compression with the staple strips in the closed position of the device, as shown in Fig. 13. They provide yieldable shock absorbing holding means for the staple strips, protecting them against breakage. In the open operative position, as shown in Fig. 14, the rearward portions of the cushion members are in engagement with the staple strips and continue to retain them in position.

In order to determine whether a substantial supply of staples is in place upon the staple rail while the device is in closed position, window slots 67 are provided in the top wall 34 of the cover part 11 near the forward end, and a slot 68 is provided in the spring portion 42a in register therewith so that the forward end portion of the staple strip upon the rail is visible through the window openings. If only one or two staples are left the upper side of the push shoe is visible through the window openings, and this may, if desired, be distinctively colored so that the fact that the staple strip is about used up is readily apparent. In addition it should be noted that, whether the cushion staple strip holding members 66 or the downwardly offset rearwardly extending leaf spring portion 43 of a spring 40 is employed, a yieldable means is provided carried by the cover part to holdingly press a staple strip within the storage compartment.

It is pointed out that if desired the spring 40a and the cushion staple strip holding members 66 may be employed in the first embodiment instead of the spring 40 and that window slots 67 may also be provided in the first embodiment.

I have illustrated and described preferred and satisfactory embodiments of the invention but it will be understood that changes may be made therein, within the spirit and scope thereof as defined in the appended claims.
