Referring to the drawings, there is illustrated a stapling device incorporating the principles of the invention in which the mechanism is suiiciently small and compact to be housed in a casing so constructed and proportioned that it has the appearance and size of a conventional writing instrument such as a pocket carried fountain line The stapling mechanism I6 is secured in a ferrule or ring member I| which is preferably formed of a short metal tubular section. The ferrule II surrounds an intermediate portion of the mechanism and forms a part of the housing for the same. The one end of the stapling mechanism l0 extends into a tubular casing I2 which is shaped to simulate the appearance of the barrel portion of a fountain pen and which has a screw-threaded connection at I3 with the ferrule II. The exposed portion of the stapling mechanism I6 constitutes the stapling head and is shown in Fig. l in the open position ready for use in the stapling operation. The stapling head may be contracted (Fig. 9) and positioned within the cap member I4 which telescopes over the same and which frictionally engages with the peripheral surface of the ferrule to hold it in connected or closed condition. The cap |4 is provided with a spring clip I which is secured on the closed end thereof by a screw |6 for fastening the same to the pocket of the user in the same manner as a pocket carried writing instrument.

The stapling mechanism ID consists of a staple storing and supply magazine I1, a bottom anvil carrying arm or plate member |8 and a top plunger shell or driving blade carrying cover member I9. The anvil member I8 and the plunger carrying cover member I9 are arranged on opposite sides of the magazine l1 and pivotally connected thereto to form therewith the stapling head which is exposed by removal of the cap I4 when it is desired to use the mechanism for driving a staple.

The staple supply magazine I'I (Figs. 5 to l0) 4 comprises channel-shaped inner and outer members 20 and 2 I, both of which are of generally upwardly opening U-shaped cross section. The outer channel member 2| is positioned at the forward end of the inner channel member 20 with its base 22 secured to the base 23 of the inner channel member 20 by means of rivets 24. 'Ihe outer channel member 2| is substantially less in length and somewhat wider than the inner channel member 20. It is arranged so that its side walls 25 and 26 extend upwardly in parallel spaced relation to the side walls 21 and 28, respectively, of the inner channel member 20 providing Y therebetween parallel guideways for receiving the downwardly extending legs of the staples indicated at 29.

The bottom or base 23 of the inner channel member 28 is cut away at the forward end to form the end edge 38, leaving end portions 3| and 32 of the side walls 21 and 28 extending forwardly of the same. The base 22 of the outer channel member 2| is cut back and provided with an upstanding tongue 33 which projects upwardly between the side wall extensions 3| and 32 of the inner channel member 20 adjacent the forward edge 30 of the bottom 23 of the same for a purpose which will be described.

The side walls 25 and 26 of the outer channel member 2| are turned inwardly at the forward end to form vertical end walls or fianges 34 and 35 having their terminating edges in opposed spaced relation and forming a vertical slot in the end of the magazine. The inner surfaces of the end fianges 3.4 and 35 are spaced a sufiicient distance from the end portions 3| and 32 of the inner channel walls 21 and 28 to accommodate a single staple and form therewith a vertical guideway through which successive staples are driven downwardly or laterally out of the magazine.

The staples 29 are urged in a forward direction in the magazine by a feed plate 36 which comprises a channel member of a size to be positioned over the walls 21 and 28 of the inner channel member 26 with the side walls 31 and 38 of the same extending downwardly in encompassing relation to the side walls 21 and 28. The walls 31 and 38 are provided with an inwardly directed detent or shoulder formation 39 which is received in the groove 40 provided in the respective side walls 21 and 28 of the channel memberI 20 to guide the feed plate 36 in its movement along the channel 20 and prevent its removal in a vertical direction. The feed plate 36 is provided at its rearward end with a reversely bent tongue 4| to which is secured one end of a tension spring 42. The other end of the tension spring 42 is secured to the upstanding tongue 33 at the forward end of the outer channel member 2 I. The feed plate 36 is relatively short and may be retracted to permit loading of the magazine from the top with a fresh supply of staples.

The plate 36 may be held in retracted position by placing its forward edges in abutting relation with the shoulders 43 which are formed by recessing the top edges of the walls 21 and 28 adjacent the rearward end of the channel member 20. The groove 40 is offset at 44 to accommodate the detent 39 in the retracted position.

A staple retracting plate 45 (Fig. 8) is arranged for limited sliding movement on the forward end of the magazine I'I to permit the staples to be moved toward the rear of the magazine a sufficient distance to withdraw the end staple from driving position. The staple retracting plate 45 engages over the tops of the staples in the magazine. with its: side edges:V extending into :recesses 46 providedin thetop edges*l of thesidewalls 25 andl26 Voffthe outerchannelmember 2 .f The por- .tionsof the sidetedges of theretra'cting plate 45 vmovement of the retracting. plate 45..

The hook 50 extends downwardlyA a suicient distance to eng-age the bight or base portion of the endstaple 29. The recesses 46 in the side -walls and 26 of the channel member 2| are located sufciently far 4above the tops-of the side vwalls 21 and 28 of the channel member 28 to permit sliding movement of thestaples `between the retracting plate 45 and the side walls 21 and 28.

The retracting plate 45 Ais provided with an upstanding pin 5| adjacent its rearward end by means of `which it may be manually-moved in 'a rearward direction to retract the staples in the magazine by engagement of the hook 58 with thev end staples. The retractingl plate 45 is provided witha rearward extension 52which projects within the ferrulewhen the magazine-isassembled with the-casing and holds the rearward end of the same in position in sliding relation with the channel member 2|. -i'Ihe retracting -plate 45 is provided at its forward end with an elongate aperture 53 so-that the supply of staplesV in the magazine will be visible to the user.

T-he ferrule is--provided with an'internal recess-54 which is generally rectangular in cross section and of suicient size to receivein-tight fitting -relation the-magazine l1. The -bottom 22 and side walls 25 and 26 of the outerfch-annel member 2| extend into the aperture -54 and dimples 54 are provided onl the sidewalls 25 and 26 `which snap into holdingrelationwith the inner marginal edgesof the aperture' 54 in the ferrule when the ferrule is forced=over the rearward end of the channel member 2| (Fig. 2). A set screw- 55 (Figs. 1 and 9) may be provided in the ferrule for rigidly securing the ferrule on the magazine l1.

IThe casing member 2 is provided vwith an internal chamber -formingbore 56 whichiterminates at the rearward end in an abutment 51 for engagement by the-rearward end 58 of the channelmember 28 to limit the movement of theferrule relative to the'magazine I1 and to properly position the same for securing by the set screw 55.

The Vanvil carrying arm I8 comprises a spring metalplate-like member having an end portion provided with transversely extending shallow recesses 59 for clinching the legs of the'staples. The member 8 is provided adjacent itsk rearward end with parallelupstanding side wall formations 60" and 6| andv 'trunnion formations "62 and 63 which. extendsomewhatpaabove 4the 'side `walls 60 andi t. and-which aregaplertured tdreceiverpivot 4forming lpins64 and '65.1' The. side wa'llformati'ons V6|]V andsl. andthe trunnion'formations- Y621. and' 63 .on the:respective;sidesrof the member I 8 `are in the same plane, and embracein close'ttifngrelation .the kside walls 25; yand l26 of thermagazine outer channelmember 2 I.; :The pivot :.pinsnM'and 65 areisecured in.aperturesl .-661 in therespective sidewalls' 25 and 26-Loftheouterichannelmember 2| to'pivotally support `the anvil; armf|8vbeneath the magazine |1'with;1theforward rendextending beneath .thevertica'lstaple driving'guideway; and

At the rearward end the sideiwalls 12'. and ,'|3 'of the cover member I9 are recessed at 14 and15 to accommodate the upstandinglwall .formations 60 and Elton the anvilsmember |13. The: side walls 12 and 13 are alsoprovided at the rearward-.end

with generally downwardly opening .circular :slots 16 andi 11 in which the 'trunnionaformations E2 and 63 on the anvilmember .I8 are received to pivotallymount the cover membersl 9 on the .trunnion formations 6.2Y and 63'. The portions ofthe sidewalls 12 and`13fdening the bottom `edges of recesses 14- and 15 engage with the opposed top portions :of the sidewalls 60? and '6|' of the'anvil carrying member I8 upon closing movement of the coverV member |9.to limit-the'movement of the same towards the magazine |1.` The top portion 18 Aof the cover- |9 is provided with a rearwardly opening slot 19Vat its rear e'nditor accommodate the Vpin 5| projecting upwardly lfrom lthe staple retracting plate 45 and to permit movement of the retracting plate 45longitudinallyiofvthe magazine |1. -One or'both of theV cover: sidewalls 12 and 13 are provided` with an inturned lug formation 88 vat thevforward end of the recesses 1d and 15 for engagementl in aI vertical` slotf8| provided in the adjacent side wall of the outer channel member 2|which provides an interlocking -connection-between the cover member |9and the magazine |1, limiting their relative movement away from eachother and retaining the same'in assembled relation. The lug-'formation may be sprung out of the slot 8| for disassembly by means of a suitable pointed tool'.

vThe cover-*memberl I9 is shapedattheforward end vto provide va driving blade formation 82. The driving blade or plunger 82 is preferably formed by turning the forward end -of the top wall 18 downwardly and shaping the downturned portion to provide an outwardly ols'et central rib formation 83 and side or end blade formations 84 and 85. The rib-like offset portion 8`3-rides'in the space between-they end members-34 and 35 of the outer channel member-2| and prevents any lateral stressbeing transmitted 4to' the pivot by movement of the plunger 82 in the staple driving operation. The plunger 82 'is separated at the sides from the side walls 12 and 13 and the latter extend some distance beyond the forward face of the magazine I1 to give added protection to the plunger. The hook-like portion 5U of the staple retracting plate 45 projects into the inwardly opening recess formed by the rib 83 of the driving blade formation 82, when the plate 45 is in its forward position, permitting the foremost staple to be engaged by the blade formations 84 and 85 for the driving operation.

The cover member I9 is provided with an elongate aperture 86 at its forward end which is in general alignment with the aperture 53 in the forward end of the staple retracting plate 45 to permit the user to observe the supply of staples and also to permit the removal of a jammed staple, if necessary, during the operation of the device, without disassembly of the parts.

The cover member I9 is normally urged upwardly away from the magazine I1 by a small leaf spring 81 which may be conveniently secured to the top of the staple retracting plate 45 by the operating pin 5|.

The top wall 18 of the cover member I9 is rounded where it merges with the side walls 12 and 13 to conform to the inside contour of the cover member I4 when the latter is placed over the stapling head (Fig. l). Y

In using the device for a stapling operation the cap I4 is removed as shown in Figs. l to 5 and 9 allowing the plunger shell I9 and the anvil carrying member I8 to move outwardly away from the magazine I1 to the limit of their movement. The paper or other material 88 (Fig. 9) to be stapled is positioned between the anvil member I8 and the magazine I1 while the stapling head is gripped bythe user, with the fingers engaging the cover member I9 and anvil member I8. The members I9 and I8 are then pressed towards the magazine I1 to move the driving blade 82 through the Ivertical `guideway at the forward end of the stapling head and to drive the endmost staple 29. I

When it is desired to replace the cap I4 on the stapling head the pin 5I is manually retracted to withdraw the endmcst staple from the driving position and the cover member I9 and anvil member I8 are moved into closed position relative to the magazine I1 and held there while the cap I4 is positioned over the same and frictionally engaged with the ferrule II.

When the supply of staples is exhausted a fresh supply may be placed in the magazine I1 by removing the barrel I2 of the casing and retracting the feed plate 3B to expose the top of the magazine. If desired the feed plate 35 may be held in retracted position by engaging the forward end of the Vsame with the abutments 43 while the desired supply of staples is loaded into the magazine through the open top of the same. v Y

While particular materials and specific details of construction have been referred to in describing the illustrated form of the device, it will be understood that other materials and other details of construction may be restorted to within the spirit of the invention.
