Fig. 17 is a perspective view of a slightly modified detachable bearing.

Illutrative of rthe embodiments disclosed, the stapling machine SM comprises magazine M for housing a strip of inverted U-shaped staples S, the bearing or support B, 'the one piece driver or bar D, the staple pusher or follower F, and the sheath or guide G.

The magazine is a one piece shell of suitable sheetmetal having bottom wall I for directly supporting the spaced legs of the staple strip, the upstanding side walls Il for guiding the staples towards guideway I2, and inwardly overhanging flanges I3 which it is important to observe have the dual purpose of preventing admission of staples into the magazine through the open top thereof and also serve to prevent displacement of the staple strip after having been admitted into the magazine through the open rear end I4 (Figs. l and 6) of the magazine.

The foremost staple of the strip is projected into the staple guideway I2 by spaced forwardly extending `legs I of the staple pusher or follower F having depending perforated ears I3 slidably guided on rod I1 xedly carrying at its rear end block I8 against which the rear end of the normally expanded coiled spring I9 bears. This spring surrounds vrod I'I and also abuts the rear ear I6 to urge the follower constantly in a direction towardsraceway I2 constituted by the upwardly extending tongue 20 and the U-shaped sheath 2| having its front wall 22 appropriately spaced from tongue 20 and having its sides 23 xedly anchored to the side walls I I of the magazine.

Of importance are the transversely spaced but aligned and upwardly extending projections or detents 24 struck out of the inwardly overhanging 'anges I3 of the magazine.

Slightly oiset butto the rear of the lower aligned detents 24 are the upper aligned and depending projections or detents 25 struck out of the `spaced flanges 26 of the guide G.' Flanges-Z are'above and spaced from flanges I3 of the magazine to dene therewith spaced rectilinear gaps 2'I (Fig. la). Flanges 26 are bent inwardly from sides 28 of the guide G and these sides straddle and are against the upstanding sides II of the 5 magazine having its bottom wall I0 secured to the bottom wall 29 of guide Gr by the spaced rivets 30.

Effectively interlocking with aligned detents 24 of the magazine are the wallsof the transversely aligned indentations 3l formed by upwardly projecting detents or projections 32 struck out of the rectilinear bearing or plate B provided with the central boss or seat 33 extending above the elevation of the margins or shoulders 34 which embody projections 32, the arrangement being such that shoulders 34 may be quickly set between the vertically spaced flanges I3 and 26 into the aligned guide gaps 21 whereby the bearing B may be bodily slid towards the front of the magazine. On such displacement spaced detents 32 of the sheet metal bearing B snap slightly by the downwardly projecting detents 25 of guide G to also interlock with or snap into the upwardly projectingdetents 24 on the magazine (Fig. 8). By this arrangement primary and supplementary locking means are provided, the primary locking means being constituted by the complementary and

separable detents

24 and 32 while the supplementary locking means may be said to be characterized by the cooperating

detents

25 and 32, detents 25 also frictionally bearing against projections 32 and serving to prevent accidental disengagement ofthe primary locking means.

As illustrated in Fig. 8 detent 25 is out of alignment with

detents

24 and 32. These detents of course may be in alignment as illustrated in Fig. 9. In either case the intervening detents are held disengageably interlocked with the detents of the magazine. In the form shown in Fig. 9 detent 25 frictionally bears against detent 32 and serves as supplementary means to maintain the lower cooperating detents 32" and 24 against accidental separation.

The staple driver D may be said to be a handle to facilitate shifting of the bearing B into and from its interlocked relation with the magazine M and guide G. Driver D is formed from the relatively hard and resilient one piece steel bar having theV horizontal rear or posterior portion 35, the intermediate inclined portion 3B, the depressed portion 31 and the forwardly arranged and depending Tshaped driving blade 38 adapted to be elevated above guards or stops 39 and into sheath 2l to be arranged over the forward staple of the staple strip S` (Fig. 2).

5 More particularly the rear rectilinear end 35 of the driver rests on the rectilinear boss 33 of the' bearing B and is at all times spaced from shoulders 34 0f the latter. Fulcrum pin 4l? appropriately upset, at its ends rotatably retains 60 end 35 against boss 33 and driver D is consequently swiveled relative to the bearing B or the latter may be swiveled in respect to the driver.

When the bearing B is interlocked with the magazine, it is effectively anchored against acci- 35 dental displacement and consequently the driver may be swiveled from its overhanging position shown in Fig. 3 about pin 43 to its staple driving position illustrated in'Fig. 2 where the slidably guided driving blade 38 if directed downwardly 70 upon application of manual pressure on the depressed portion 3'I drives or expels the staple from the guideway onto the clinching anvil A.

. In the position of the driver shown in Fig. 3, it may serve as a handle adapted to be grasped and 75 pulled outwardly. This action causes the interamamos mediate rdetentsfz tofsnaprover .aa-riduce .freeofthe cooperating interlocking detents .-25 and 121!r .and almost coincident with such disengagement v"the bearing .B is 'completely :withdrawn .from the magazine. .It :follows that .the T-shaped block .I'B xedlyfcarrying rod -L .may then vbe lifted from .alined .notches 4 i, :thus 4unlocking :from :the magazine and therefore :thefollower rod may y:be withdrawn through :the rear open `.end i4 of the magazine :carrying with .it Ythe .-staplefffollower F.

JQfvcourseonce-the pusher F is removed and the interior of the maga-zine is clear ofintertference -due to ipieces of glue or fragments of staples, .a fnew :strip .of staples may be quickly Ainserted into the magazine :however through the rearlopening:Maonlyafter which rod I1 with .the slidable pusher F Tandfspring I9 thereon is Vrestored therein -and block I 8 locked by the walls of lnotches 4-I whereby eachfsucceeding foremost staple of thestrip fisalways urged in the raceway and under 'the driving .blade `38.

Having locked block I8 to the magazine filled witha-supplyfofstaples, the accessible front end SB =of the `bearing B Vis now inserted 'in the guide openings -2'1 (Fig. 11A) and .urged forwardly by pushing the driver 'D forwardly. This .action causes `the bearing to interlock with both the magazine and guide as previously pointed out. Therefore driver :D may be swung to arrange 'its vdriviing 'blade 38 towards the :near sheath i2! `at which time due =to loosenessfor play of .the rear end 35 on fulcrum pin 4H, .the 'blade 3B may .be conveniently lifted over guards .or ystops .39 into the guideway VI2'where itiis reciprocably guided to iexpel .the foremost staple after .which :upon release of themanualfdownward pressure onthe driver, '.the intermedial :portion-3B, .the depressed portion 2:31, :and the driving blade automatically retract :due .fto lthe linherent resiliency `oi 'the driver nto arrange the hlade just ab'ove .the :foremost lstaple although `it vshould i.be f'noted that downward displacement '.of fthe .blade is limited when shoulders 42 of the .driving blade -strike stops :or guards L39.

In the form illustrated in Figs. 2 and 3, the rear end of the bearing B extends above the alined openings 4I, and prevents withdrawal of the end plate or block I8 when the bearing is in a locked relation. In accordance with the embodiment shown in Figs. 13, 14 and 14A and as previously stated the rear end 5I serves in part as closure means for the rear end of the staple admitting opening I4.

However in all of the embodiments according to the invention herein the driver is a one piece metal bar adequately resilient and effectively swiveled on the bearing and adapted to be flexed downwardly relative thereto when locked preparatory to driving a staple out of the magazine and pursuant to such action and upon removal of finger pressure on the driver the latter automatically is elevated or retracted due to its own resiliency to arrange the driving blade again just above the foremost staple. In all the forms disclosed the driver is carried by the detachable bearing and in Figs. 13-15 may be said to permanently carry the staple follower and in each instant however the driver in fact may be considered as a swiveled handle to facilitate threading and locking the bearing or carriage B to the magazine. Of course when the driver is swung laterally or rearwardly of the magazine it also serves to facilitate detaching the bearing from the magazme.

By the present invention it is apparent that the herein stapling machine comprises relatively few parts each simple in structure and when such parts are assembled they constitute a relatively small yet simplified stapling machine conveniently adapted to be carried about by the user and in a small pocket of the latters clothing.

Various changes may be made in details of construction and arrangement of parts Without departing from the spirit of the invention or sacrificing any of the advantages thereof inherent therein.
