Application filed May 11, 1918. Serial No. 233,922.

To all whom t may concern.'

Beit known that I, J oHN WILLIAM HAW- KINs, al citizen ofthe United States, and a resident of Kokomo, county of Howard, and State of Indiana, have inv *ed a certain new and useful Staple-Einem; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which .like numerals refer to like parts.

This invention relates to staple binders and the prime feature of the invention is the provision of means for driving staples through the folded parts of books, pads and other articles for holdingthe same inv assemi bled formation.

A further feature of the inventionl is the provision of means for feeding the staples one at a time from a core or support,

, into the path of a driving hammer and al- 4'ways maintaining the same in van upright lposition for driving purposes.

`A further feature of the invention is lthe provision of means for clenching the ends of the vstaple after it has been applied to use. A further feature of the invention is in the provision of adjusting means for adjusting the work supporting table toward or from the staple receiving head and likewise nieansv for adjusting the clenching mechanism.

A further feature of the invention .is the provision of interchangeable parts employed for carrying the driving hammer and also interchangeable parts for guiding the staples in their passage from the core to the point to be engaged by the drivin hammer, the requirement for the intere angeable parts-being to accommodate staples of varying lengths and widths.

A further feature of the invention is the provision of an operating mechanism for simultaneously elevating the supporting table and lowering the driving hammer, and 1ike- Wise operating the clenching mechanis1n which mechanism may be operated either manually or otherwise.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims In the drawings, Figure 1 is a perspective view of the staple binder ready for operation. Fig. 2 is an enlarged side elevation thereof showing parts removed and parts broken away. Fig. 3 is a similar view show'- head as seen from the dotted line and arrows in Fig. 2, and Fig. 7 is a sectional view as seen on line 7-7 of Fig. 2.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the base of a staple driver, extending upwardly from which is a frame 2, one end of the frame having a forwardly extending horizontal section 3, which terminates over an arm 4 at the opposite end of the frame. The forward end of the horizontal section 3 is provided with a head 5, said head having guide bars 6 removably secured therein and between said guide bars is positioned the driving hammer 7. j The inner faces of the guide bars 6 are provided with longitudinally extending channels 8 in which travel the wings 9 of the driving hammer, said channel also receiving and guiding staples 10, while they are being driven by the hammer.

The driving hammer 7 is pivotally attached to one end of a rocking arm 11 by means of a link 12 and as said rocking arm is pivoted between its ends to an ear 13 extending upwardly 'from the horizontal section 3 of the frame member, so that the hammer 7 will be raised and lowered as the rocking arm is swung on its pivot. The guide bars 6 are held in engagenient with the head 5 by means of screws 14 which extend transversely through the bars 6 from the front face thereof and thread into the head 5, so that said guide bars can be quickly removed and interchanged when staples of different sizes are to be used. The front face of the head 5 is provided with a vertically extending channel or recess in which the guide bars 6 are placed, one at each edge thereof, so that the rear face and one edge of the guide bar 6 will rest against the side. walls of the recess in the head.

The staples 10 are carried on a. horizontally disposed core 15 which enters a slot 16 extending 'longitudinally of the horizontal section 3, the core being held in position by means of a guide block 17 at the forward end of the core and a. lock block 1S at the rear end of the core, the guide block being ywhile the locking block 18 is held in position by means of a screw 20. The staples wardly into engagement with a winding drum 25, rotatably mounted on 'a study 26 at the rear end of the horizontal section 3, the drum 25 being rotated to wind the cable thereon through the medium of a helical spring 27 one end thereof being attached to the stud and the other end to the winding drum.

'The core 15, which is channel shaped, is held in place by means of a cover plate 28, fitting over the channel in the horizontal section 3, and by introducing` the ends of the core over shoulders 29 and 30 on the blocks 18 and 17 respectively. In removing the core 15, the co-ver plate 28 is removed.

and the screw 20 then removed which releases the locking block 18 and'by moving said block rearwardly the core 15 can be released from the shoulder 30 on the guide block 17. The core is then removed from the slot 16 and a new core containing a new supply of staples introduced into position,

' which is accomplished by engaging one end thereof with the shoulder 30 and then moving the locking block 18 into positio-n, and

securing it with the screw 20. The follower 21 is then moved to the rear end of the core 15 and introduced thereover, and by returning the cover plate 28 to position the stapling device is ready for use.

In order to permit the staples to pass forwardly into alinement with the channels 8 of the guide bars 6. mandrels 31 are introduced through openings 32 in the head and guide bars 6, said mandrels having ways 33 cut therein which permit the staples to move forwardly until they strikeV theouter walls of the channels 8` and as staples of different lengths are tolbe used, the mandrels 31 are interchangeable sc that when longer staples are being used, mandrels having longer ways 33 therein are to be introduced into the openings 32, the mandrels the guide block 17, the upper face of the guide arm being preferably curved or con cave so that when the staple is forced downwardly by the drivinghammer 7, the guide arm 35 will be forced 'downwardly as the lhammer descends, thus permitting the staple to leave the guide arm and pass on through the channels 8. Y The staples, as they leave the channels 8, are forced through the articles to be stapled, (not shown), which may be in the shape of books, newspapers, pads, or other forms of devices which are supported upon a platform 38,' which platform .is carried by a tubular rod 39, said platform resting upon a support 40 having a sleeve 41 thereon which fits over the upper end of the tubular rod. 39. The free ends of the staples after` they are driven through the article being stapled, yare upset or clenched by means of anvils 42 which are pivoted at their outer ends in a retaining member 43 mounted upon the support 40, the inner ends of .said anvils having shanks 44 thereon which limit the downward swing movement of the inner ends of the anvils, said anvilsbeing so constructed that they normally rest at a downward inclination, the incline being from the Vclenched by forcing the inner ends of the .anvils 42 upwardly thereby pressing the ends of the staple in close engagement with the lower face of the article being stapled.

The anvils 42 are forced upwardly by eX- tendi a shaft 45 through thetubular rod the sleeve 41, the upper end of the shaft having an enlarged head 46 which engages the Shanks 44 of the anvil, thus forcing the inner ends of the anvils upwardly when the shaft 45 is elevated.

The sleeve 41 is vertically movable through a bearing 47 attached to the end of the arm 4` so that'the sleeve 41 and parts cari vried therebymay bemoved upwardly to properly positionI the article tobe stapled adjacent the lower ends of the guide bars 6.

The tubular rod 39 and 'the'shaft` 45 are elevated through the medium of a lever 48 which is operated 1by hand and is'pivotally attached to the vertical portion of the frame 2, although it is to be understood that the device can be operated by foot power, or by motor if desired. The tubular rod 39 is op-A erated by means ,of a cam 49 which depresses a plunger 50 slidably mounted in a guideway 51, the upper end of the plunger having a friction roller 52 for engagement with the cam 49, while the lower end thereof is provided with a friction roller 53 for engagesaid notch fitting over a crank portion 56 of a pivot 57, the ends of the pivot being rotatably mounted in ears 58 depending from the base l and 'by suspending the rocking le' ver 54 in this manner it may be swung endwise when one end thereof is depressed to elevate the opposite end, thus permitting thel elevated end to travel in a substantially vertical line.

The forward end of the rocking lever 54 is .provided with an upwardly curved portion 59 and a horizontally extending portion 60, the horizontally extending portion being bifurcated, which bifurcated portions are provided with notches 61 which engage pins 62 carried by a collar 63, said collar being internally threaded for engagement, with the external threads 64 on the tubular rod 39.

By threading the collar 63 on to the tubular rod 39, the tubular rod may be adjusted to raise or lower the support 40 with respect to the collar and to more readily accomplish the rotation of the tubular rod a milled disk 65 is fixed to the tubular rod 30.

The shaft 45 is likewise moved upwardly l `to operate the clenching anvils 42 through the medium of a rocking lever 66, which is pivoted to ears 67 also depending from the base member 1, said lever being pivoted at its outer end to a collar 68 which is threaded on to a sleeve 69, into which the lower end of the shaft 49 extends. The rocking lever 66 is also operated from the lever 48 by extending the pivot pin 70, to which the` lever 48 is attached, entirely through the frame 2 and secured to the pivot pin on the opposite side of the frame is a cam 71 which coperates with the verticall extendin plunger 72, likewise slidab y mounte through the base 1, the lower end of Said plunger resting upon the inner end of the rocking lever 66.

The shaft and the tubular rod 39 may be simultaneously elevated by extending an adjusting screw 73 through the lower end of the sleeve 69, or the shaft 45 may be adj usted independently of the adjusting screw 73 by rotating the sleeve 69. The tubular rod 39 and the shaft 45 are held against independent rotation of each other by extending a pin 74 through the shaft 45 and having one end thereof entering a slot 75 in the tubular shaft 39, while the shaft 45 is held against independent rotation of the sleeve 69 by means of a pin 76 which extends through the'y shaft 45 and has one end entering a slot 77 in the sleeve 69. By providing the adjust-- ing means as shown for the tubular rod 39,4 the platform may be adjusted to accommodate articles of various thicknesses and by providing an adjustment for the shaft 45, the degree of bend of the clenched portions' of the staple may be regulated.

Simultaneous with the elevating of the platform 38, the rocking arm 1l is operated to lower the driving hammer 7, this being accomplished yby attaching a shank 78 to the pivot pin and connectin the opposite end of the shank to the depen( ing end 79 of the rocking arm 11 through the medium of a link 80.

In operation, the article to be stapled is placed upon the platform 38, or if the work to be stapled is in the nature of a book, or article having pages to lbe turned and opened., that'form of platform 81, shown in Figs. 2 and 3 is used, and when so placed the lever 48 is swung from the position shown in Fig. 2 to the position shown in Fig. 3. The forward movement of the lever 48 causes the cam 49 to lowerthe plunger 50 and consequently operate the rocking lever 54 to elevate the supporting table and parts carrying the same, thereby forcing the article to be stapled against the lower ends of the uide bars 6. During this movement 'of the ever, the rocking arm 11 is operated to lower the driving hammer 7 which forces the staple 10 downwardly and through the article to be stapled. The lever 48 is then swung rearwardly to its initial position, this operation causing the cam 71 to operate on theplunger 72 and thus force the shaft 45 upwardly through the medium of the rocking lever 66 and causing the anvils 'l2 to clench the projecting ends of the staple, this operation being performed before the cam 49 has reached a position to release the rocking lever 54.

As soon as the lever 48 has returned to its initial position, the rocking levers 54 and 66 are released, thus permitting the shaft 45 .and the parts carrying the work supporting platform to descend and at the same time the rocking arm 11 is oierated to elevate 'the driving hammer 7, whereupon the next succeeding `staple will be entered into the channel 8 and in position to be enga-ged by the driving hammer when it is again lowered. A new article to be stapled may then be Iplaced upon the platform and the previously described operation repeated.

By constructing the device in this manner all of the parts are very compact and at the same time rendered strong and durable and occupy but a small amount of space when positioned ready for use. It will likewise be seen that by forming the guide bars 6 interchangeable with the head 5 and by providing the interchangeable mandrels the same machine may be employed for using .staples of various lengths and widths, the driving hammer 7 likewise being interchangeable so as to accommodate the same to the various widths of staples used.
