Our improved staple bindercomprises certain fundamental features of construction and operation that are similar to features that are "found in the device shown and described in the application referred to above.
Thus there is the base 10 that has the anvil Eat the front end for clenching the staples 12 in cooperation with the plunger 13 after they have been severed from the staple strip to which they are connected as supplied-to the machine and are forced downwardly by the continued movement of the said plunger.
At the rear end of the base 10 is a pair of upstanding cars 14, in spaced relation, that support the pivotal pin 15.
The base 10 serves as thefixed member, and a moving member, designated generally by the character 16, is operativelyconnected thereto by the pivotal pin 15.
A pair of ways 17 at the front part ofthe moving member '16, positioned in spaced relatio'n, engage withthe sideedgeportions of the plunger 13 and serve to guide the a,
plunger in. its upward and downward ment. The filler piece 18 that extends 511 1;; :the bottom of the moving member 16, and,
the two side plates'19 of the framef or casing; has the upper portio'n 2 O reduced n width so as to servejas the guide f onthe staple strip; supports by its front endthe posed to the base 10,'is positionedb ween die 21,v which latter is'in the formofa sepa;
rate and removable piece'ysupportsl by the lower'portion '22 'suitabl'e dowel pins 231 for positioning the side plates j 19 ;v and has the rear end portion extended between the ears 14 and pivotally suPPQI'tBd'by the pin 15].
,The saidbottom portion' 22 also .has' holes f r .i h l in gs rewsz ez e ingt S .P a e19' the; i iilnr smgi he. s en 24" at the rear. and the front scr 25'? As. will e q'r Ydilt s ry w so t j j memis for bold die 21in place ffthe a f grg member I 16. 9. formed "y. the s de pla s lama"ihaeih ei tioned in spaced relation to provide a housing for the staple moving or feeding mechanism that cooperates with the plunger 13. The form of the said upper part of the "casing is generally triangular, with a sloping or inclined rear and upper wall 26,'and the closure for the said rear and upper portion is provided bymeanspf inwardly turned, opposed flanges 27 on the side plates 19.
At the upper, front part of the casing, being at the upper ends of the ways 17, is a seat 28 for a spring 29 that cooperates with a knob 30 at the upper'end of the plunger 13 so as to tend to hold the said plunger in the uppermost position.
The staple strip feeding mechanism is similar to that shown and described in the application above referred to, being actuated by a lug 31'on the plunger 13, and comprising afeeding pawl 32 and a holding pawl 33.
The feeding pawl 32 is supported by a pivotally sup-ported dog 34, the latter havmg a lug 35 cooperating with the lug 31,0n the plunger 13, and a spring 36 servegato position the said feeding pawl 32 rel 'tively v to the dog 34.
A spring 37 serves to position the holding pawl 33. K
The features involved in the present invention comprise indentation ,of the body portion 38 of'the side plates 19; the construction of the filler piece 18 of sheet material; the construction of the die 21 of sheet material; the construction of the plunger 13 of sheet material, comprising the plunger body 39-as well as the fin plate 40 that has the lug 31; utilizing the said indentation of the body portion 38 as part of the way 17 for guidingthe plunger 13' and also as a stripper for the upper, guide a portion 20 of the filler piece18; and certioned.
tain other features incidental to those men- As to the indented body portion 38 of the.
1 side plate 19, this comprises the major portion of the plate, which is'made of sheet metal,'so that the indentation serves to re as shown, and conforming to the inforce and stiffen the side plate generally. The form may be .substantially triangular, general form of the side plate 19, with the ma'o'r portion of the upper, rear indented e e 41 inclined and .in a manner similar tot e flane27andwall26. i f
T e bottom edge 42.of the indented body portion 38 is straight; extends alongside the upper, guide portion 20 of the filler piece 18 so as to be positioned above the staple strip mounted thereon. andserves'ta's, a =gu1de for the said staple strip as it is fed along towardsthe plunger 13 and die 21; and. the
part of the 'said bottom edge 42 adjacent the die 21 is adapted to engage with the vstaple strip in case of a lifting movement vtom, guide edge 42.
to the rear face of the plunger body 39. Only part of the said front edge is used for this purpose, as shown. This for the reason that a relatively sharp structure, with a pronounced corner is desirable for backing the plunger 13 in its movements, and that it is unnecessary operatively and from a structural standpoint undesirable to provide such a superior structure for the entire length of the said front edge that is opposed to the plunger 13.
In the structure shown the rear wall 43 of theway 17 may rupted form, with an active portion at the top and a second active portion at the bottom, the portion 44 of the said front edge intermediate these parts being of rounded form, so as to clear the plunger. 13 generally. The rear wall 43 terminates at the top corner 45 of the indented body portion 38 at the upper end and at the lower end meets the corner 46 at the junction with the bot- The filler piece 18 is. made of sheet metal, bent generally into U-shape, the upper portion 20 being reduced relatively to the lower portion 22, there being a longitudinally directed shoulder 47 on each side at the junction of the two portions. Thus, the botbe described as of inter- 1 tom portion 22 consists of two similar side walls that extend downwardly from the j shoulders 47, separated by. the open space 48 and which fit between the cars 14 that provide the support for the pivotal pin 15 The die 21 is fitted to the front end of the filler piece 18; has side Walls 49 that fit within the 0 en space 48 in the bottom portion 22 of t e said filler piece 18; has at the front end a plate-like, upwardly direct-- ed cutter plate 50 that abuts against the opposed end'face -51 of the filler piece 18; an at the lower portion a base plate 52 that extends along the bottom and, in use, rests on the anvil 11. t
The cutter plate 50 is shaped to correspond to the end face 51 and serves as the vactive die or' cutter for severing the individual staples 12 from fhe'staple strip in cooperation with the plunger 13, the cutting edges bein located. at the upper, front corner 53 of t e cutter plate 50 and the lower rear corner or edge 54 of the said plunger13. The die 21 may be made of a single piece of sheet material from a blank such as is shown in Fig. 13 that has at the front end the portion that serves as the cutter plate slits 57 The back plate 55 is operated upon by a combination of bending and swaging so as to bring the side walls 49 in the upright position relatively'to the bottoni"or.,base; 52, the two lines 58 indicating approximately the lines of connections of these parts, and also, as indicated by the curved line 59 connecting the side lines 58, there is material provide a reinat the rear end that serves to forcing wall 60.
The side walls 49 are provided with suit-,
The rear wall 43 of the. way 17 has been described, corresponding to the front edge of the indented body portion 38. A flat or plain border encloses the said body portion 38. The part 62 of the-said fiat border portion in front of the rear guide wall 43 constitutes the side wall of the way 17. The front wall of the way 17 is formed by an inwardly turned flange 63 on the sideplate 19, being turned inwardly from the edge of the side wall 62- just described.
At the upper endof the way 17 is the seat 28 for the spring 29, as mentioned, and
the front portion of the said seat 28 is in h the form of a forwardly directed finger 64 that is integralwith the inner edge of the guide flange 63.
The engagement of the ways 17 with the plunger body 39 is confined to the edge portions 65 thereof. a
The said plunger body 39 is rein-forced longitudinally by means of a rib 66, pro jected forwardly relatively to the said edge portions 65, In the formation of the rib 66 a groove 67 is provided on the rear face, and the said groove isutilized as a seat. for the fin structure 40, which is embedded therein edgewise. A plurality of'rivets 68 integral with the fin structure 40 may be used to hold the same in place.
In addition to the integralrivets 68 the fin structure 40 has at the upper end a forwardly directed lug 69 that extends through a slot 70 in the plunger body 39 and on the rear or inner side or ed c has intermediate its length a shoulder with the opposed portion 74 of the casing 3 for cooperating for limiting the upward movement of the plunger.
Thus at the upper end of the plunger 13 is'provided a seat 71 for the knob 30, comprising the plunger body 39 and the fin structure 40 at right angles, one to the other,
the edges of these parts being opposed to the said knob 30." Upwardly extending riyets 72,, integral with the plunger body 39,
serve to hold the knob 30 in place.
As described, the under face of the knob 30 makes contact with the upper, tip end of the plunger body 39 and also the fin structure, wherefore, when a'blow is given to the knob to, .drive the plunger 13 the knob serves as the means for transmitting the effect of the blow directly to these parts of the plunger.
