To all whom it may concern: Be it known that I, GEORGE P. BUMP, citizen of the United States, residing at La Urosse, Wisconsin, have invented certain new and useful Improvements in Machines for Fastening Paper or like Sheets Together, of which the following is a specification.

The invention relates to a machine for fastener or tie disclosed in Letters, Patent of the United States No. 1,009,644, dated November 91, 1911. My present invention isanimprovement upon. that form of machine disclosed in Let- United States No. 1,065,903, dated June 24:, 1913, an example of such type of machine being illustrated 1n Letters Patent of the United States, No. 966,598, datedAugust '9, 1910, granted to R. B. Reasoner, myobject being to increase of the tool, reduce it to a minimum size or convenient handling, and to simplify and reduce thecost of manufacture.

The tool comprises generall two jaws, one carrying a die or shear p ate and the other carrying a punch or cutter to cut a tongue from the sheets of paper which are to befastened together, said cutter operating in conjunction with the shear plate to form this tongue. Associated with the tongue and a needle, which move slit in thepaper and having an eye-into which the folder forces the end of the that as the needle retracts through. the slit in the superimposed sheets, it will'draw the tongue therethrough and thus complete the fastening together of the sheets.

In the drawings Figure 1 isa side view of the complete tool; Fig. 2 is a part sec. tional view and elevation, the part shown in section being the lower handle with its housing; Fig. 3 is a sectional view of the upper handle with all the working parts connected therewith, the lower handle with its housing being removed; Fig. 4 is a side view of'the Fig. 4 is abottom plan view ofthe lower handle member andahousing; Fig. 1 is an end elevation *of I the lower handle member and housing look Fig. 7 is a, plan-view of the stripper. plate; Fig. .8 is a plan view of the shear plate; Fig. 9 is a. side elevation of the upperjaw; 10 is an'end view of said upper jaw; Figs. 11

In these drawings, 1 is a shear plate and 2 .the stripper plate which receive between them the sheets of paperwhich are to be fastened together, 3 is the tongue cutter or punch, 1 the needle, and-5 the tongue tucker or folder. The shear plate or die is carried by a lowerjaw 6. This jaw may be con-' 14 is a'bottom plan viewof Fig.

in the particular form shown it is secured to a lower handle member 7 by screws 8, 9, a pair of said screws being oneach side of the tool, as will be hereinafter described. The stripper plate 2 is secured at its rear end by a screw 10 to the shear plate, and this stripper plate is formed of spring metal the tendency of which is-to close down upon the shear plate, it being normally held up by means, hereinafter described:

The punch or'tongue cutter 3, needle 4, and tucker or folder 5 are mounted ,u'pon an upper jaw ll, as will be hereinafter described. This upperjaw has-a pin and slot connection at 1 2 with. an upperhandle lever 13, which latter. is pivotally connected with the lower jaw- 6 by the screws 8. The upper and lower jaws jar-e further connected to-' getherby a pairof links 14. pivoted to the upper-jaw at 15, and having a pin and slot connection at16 with the lower jaw. The links arepivoted at 17 to the upper handle lever.

A spring 18 attached atone end to the upper jaw at 19 and at its other end to the pin 12 of the upper hand lever holds the nartsnormally in the position shown in Fig. 2. withthe jaws "separated and the stripperplate raised ready to receive the paper sheets which are 'to be united. The immediate means for lifting the stripper plate may assume various forms, but'in the particular construction shown as exemplifying my infrom the stripper plate and having their 'upper curved ends restingon the ends. of. the links 14. These arms extend up across the spacebetween the jaws and are operated from the movement of the upper jaw. As the ipper handle lever is moved down to cause the punch tocii't out the tongue from the paper, the needle,.t0 form the slit, and the tucker to turn the tongue to enter the eye of the needle; or slitter, thespring strip-- 'per'plate will move toward the shear plate.

at i'the'sa'me s ed' that the punch, tucker and needlea Vance to operate upon the paper sheets, orin other words at the same speed of closing movementof thejaws, and

- because the stripper plate is arranged in a slightly lowerplane than the: lower ends off -'said parts just mentioned, said stripper plate will engage and securely hold the paper sheets before the punch tucker and needle operate thereon, the stripper plate now re-. mainin'gfat rest while the further closing of the jaws proceeds and the punch, tucker and needleare 'operatingto make the tie; B

thus firmly clamping the paper sheets in a vance of the action of the tie formingele' ments thereon, a smooth clean tongue will befcut which will'work equally well in fine as well as the heavier grades of paper, as

all Lbuekling of" the paper sheets is prevented. S {"The flower handle member is provided with a housing 21' and in the particular form I shown this is an integral extension ofthe'" handle membe'r. Thishousing' receives'the upper handle, and all the working. parts shown in Fig. 3, including the upper handle. and all these working parts can. be removed from the housing as one body,,this groupof v mechanism being shown'in Fig. 3. This re moval can be 'eflected simply by removing the screws 8 and 9. I The-lower'handle member has no movement relative to the lower jaw they being fixed together or in effect integral with each other, the-upper handle being the only one to have pivotal movement in relation to'the jaws. The lower handle, together with the" lower jaw and the housing, may be said to bethe stationary portionof the tool, and that the upper handle, by movingdownvin relation to this fixed portion, causes'tlie upper jaw to closejupon the lower jaw, and.

' it will be observed that the movement of the sembled with the lower handle and its housing, this mechanism; is protected and concealed fromview,asshown in Fig. 1. The lower portion of the upper handle fits within this housing-also, i.

I prefer to form} the up or handle member and the lower handle wlthits housing by stamping each of these arts from a single piece ofsheet metal. 'I he housingwill be provided secured by screws 23 to ears 24 bent in from the upper edges of the housing. This stamping for the -lower handle. and housing,- as shown in- Fig. 4',"is provided 'with cars 25 having elongatedopenings 26 throu h which the screws 9 p'assfor holding t e lower-jaw 6"to the handle 7 and permitting it'sadju s'tment, for which purpose also the lower jaw'ha's elongated-openings, asat 27,

serve alsotojconnect the lower handle mem- "b'er,'lower jaw,'and upper handle together.

The openings-for these screws are located in "the 'lowe'rhandle member, as at 28.

with a cover-portion '22 which is v "receiving'the screws 8 which form the pivot connectior'r'ofE-the upper handle-member and standing side and end walls. It is provided with an opening 29 inits bottom wall. This lower jaw is 'of less width at its rear portion, asfshown in Figpfi at 30, to accommodate the'-links',14"which lie outside of,the jaw-s and'within'the'depending sides of the upper"handle ."-To the wider part of the lowerjaw th'edepending sides of the upper handle are pivoted. The shear plate 1 is held to th'eglower jaw by screws 31. The shearplate rests upon the upper edges of the end and'side walls of/the lower jaw, and it "is narrowed at its rear portion to accommodate-the'lower endsiof the upper handle member and the links 14-. The spring stripper plate is secured at its rear end by the screw 10 and nut 32, the screw passing through the shearplate and the nut fitting between the side walls of the lower jaw to prevent turning. This stripper plate has an opening 33 through which the punch 3 and tucker '5.pass,, and an opening 34 through which the needle or slitter 4 passes. It also has an upstanding stud 'or lip at the rear edgeof the opening 33 for retracting the tucker or folder when raised,'as in Fig. 3, and for retaining it in this position.

"While the. control of this spring stripper plate may be eflect'ed in various ways, I prefer as in the particular form shown to form it with 'two'integral arms 20 cut from the rear portionof the plate, and bent up therefrom with their upper ends suitably formed to engage and be lifted by a member or members moving with the upper jaw, which, inthe presntinstance, I have shown as the up er ends-of the, links 14. The stripper; plhte, Wh'enlifted, is arrested by coming against the lower edges of the housing, the arresting bearing being preferably throughout the length of these edges and? the e ge of-the endwall of the housing. It; -will 'be observed in Figs. 1 and 3 that the stripper plate is parallel with the shear: plate. This relation is substantiallyvmainmined in.-both the open and closed positions; oft-he plates. In the open position it facili-Q tates ready insertion of the paper sheets, and in :the closed position it insures the firm; holding or clamping of the aper through-{ out; the insertedportion of tie aper sheets whilethe tie is being formed. By utilizing the housing as the stop for arresting the lifting of the stripper plate, the space be- ,tween the stripper plate and the shear plate may be left free and unobstructed for the insertion of the paper sheets for a considerahle'idistance.

zlit will be observed that the lifting exerted throughthearms 20 is applie force about midway of the length of the stripper plate, and Ali-is .aids'in the maintenance of the.

parallelism'justmentioned, and another re- ;sult ofithe arrangement is that the lifting arms are concealed and protected by the housing. These lifting arms embrace the upper jaw 11. This upper jaw is a sheet metal stamping having a topwall and side walls, It is located at its rear portion within the depending sides of the upperhandle and at its front portion within the housing 21,

dying close to the upper wall of said housing .when in its normal open position, as shown :lIl Fig. 2. It is concealed and protected by the housing and upper handle.

lllhe punch-0r tongue cutterB is'stamped sup out or sheetimetal with sides inclined in .respect to each other to --c u-t a \V-.shaped tongue. Within-thispunch:the working end -of-the tucker5 is locateu, tsaid tucker, in the i particular form of -,-my iinvention .shown herein, being of spring metal, its upper end being turned downwardly, forwardly, andupwardly, ,providing a straight base portion having integral side lugs '36 fitting between the adjacentedges of t 1e tongue cutter and the shankqoftthe needle-d. These side lugs are confined between projections 37, 38, .forming integral parts .of the :tongue cutter and needleshank, respectively. The upper end of {theattaching or=ba-se portion of ;the tuckerisiprovided with a notch at38-which -receives the upper bend {of the metal strip {from which the gtucker is :formed. The tucker moves down with the upper -j aw, and hence its lower end rides-off of ithe projection or .stud 85 .and moves 'to the right to fold the paper ,tongue out by the :punch .3 into the eye of the needle, .thisimovement beingv due to the spring of the metal of which the tucker is composed. When the jaws separate,the tucker rides on theiprojec- -tion 35. and its work end moves alef-tward to the position shown in ,F ig. 3: Theseimovemeats under ieonstant use will .produce crystallization of the metal and consequent breakage were certain constructions of sprlng tuckers employed, but'with the form shown a long spring strip is provided, the bend at the top being gradual and this merging into a, free downwardly extending portion,

which connects by a gradual curve with the upwardly extendlng base or attaching portion. The spring actlon is thus distributed over a spring member of considerable length g instead of being. confined to some one point or bend, and as aresult of this new construction the life of the tucker is greatly increased. The needle or paper slitter d is also formed by stamping it up. It is provided with integral flanges 39 forming, with the main part of the needle, a shank, the edges of which, as above described, aline with the edges of the attaching portion of the tongue cutter, and being provided with the lugs 38, hold the tucker or folder in conjunction with said tongue cutter.

The dengue cutter or punch 3 and the needle or slitter -it are held within the upper jaw by a pair of pins 40 passing through notches il in the front edge of the punch. and bearing in the side walls of the jaw, and by a pair of pins 42 hearing in the side walls of the upper jaw and a Wedge .43 interposed.

between the pins and the back face of the (an shank of the needle.

The'links 1d are stamped out of sheet metal with hollow journals 44 upset. from the-metal ofthe links, these journals extending outwardly and bearing in openings in a ea the sides of the upper'handle member. This construction avoids the .use of pivot pins, liableito drop out.

The upper handle is formed by stamping dies, and is all in one piece. llt is slidab-ly (the connected to the upper jaw and pivotally connected by its extensions to the other jaw. It forms the fulcrum for the link connection, and in effect forms one member of said connection between the jaws, providing with use the links 14 a. crossed link connection.

:Both of the handles are provided with guard projections 40', these'being curved to afford comfortable bearings for the hand.

They prevent the hand from slipping too M5 far forward.

While I have referred to the member4 as a needle, itwill be understood that this may be otherwise constructed than with an .eye,

so long as it performs the functions of makaec ing the slit and drawing the end of the paper tongue up therethrough.

W here I have spoken of a shear plate or die on the lower jaw it will be understood that I do not limit myself to such plate or Mb tongue cutting and folding means on one 160 connected with the jaws one of said handles and jaws being connected rigidly and a link connection between the jaws, substantially as described.
