This invention relatesto an improved paper cutter; which is designed withv an object of preventing injury tothe user of the cutter at the time of feeding paper between the 5 blades of the cutter.
A further obj ect is to produce a paper cu t- Ater especially designed to be used in certain types of ,oiiice appliances `wherein continuous webs of paper are employed for purposes of 10. making records, and wherein portions of the webs are-removable after having made such l records. v
Afurther object is to produce a paper cutter especially designed tobe used where it 15 would be desirable to Vremove one or both of .the'lrnivesof the cutter fromv proximity with the edges of the paperY webs in order-,that ftheymay be grasped andfed forwardlybetween the knivesvprevious to the :severlng operation.
' `-These and other objects are attained in the paper cutter described and claimed in the'following specification and illustrated in the accompanying drawings, in which :.l
2 Fig. 1 is a fragmental side elevation, somewhatin section, showing an Office appliance v equipped with a'paper cutter embodying my invention.
Figf2is a view similar to Fig. 1, butshow- 30 ing the parts in different positions.
" The machine in connection with whic'hI have chosen to illustrat'emy inventiontisone especially ldesigned to. facilitate the typing of billiforms in multiple and is intended for 35' use vwith a typewriter construction, lnot 5 series of webs 7 bearing the printed forms.
These: webs. are aligned at their forward edges 8 over aligningpins or hooks 9' which enterfperforations in the webs. at their for- Ward edges. Such a clamping bar 6 is mount- 50 ed on pins 10 on each side of the webs to be Nr OFFICE PAPER CUTTER.
1929. serial No. 344,288.
clamped in amanner so that the pins reciprocate vertically and clamp or release the webs through ythe agency of the bar 6. They vreciprocation is caused by theJr engagement of an operating pin llfwiththe forkedy element .12 at the lower endvof each pinV 10,y the pin .11. engaging therslot in the fork and being causedrtol move therein by'means of the rocker arm 13 which carries each of the pins 11. Thisfrocker arm is mounted on a shaft move up .or down to cause operation of the Vclamping bar 6'. Each rocker:` arm has a forked endl in which a pin 16 on a lever 17 operates in orderthat the rocker armmay be ymoved. Each lever 17 is pivotedon a shaft 18'ex'tendingbetween the side bars 4 so that when poweris applied Vto each lever 17as at a point 19 between its-'endsythe rocker arm:
will be caused'to reciprocate. This pin- 19 af-y fords connection between each lever'17 and a yoked lever 20. This lever has no direct pivotal connection,y but preferably bears by means of an extended linger 21 oneach 'endofthe yoked lever against the shaft14 carrying the `rocker arm. The opposite end 22 of theyoked lever carries the hooked end 23 of a link 24 which extends downwardly to a foot treadle, not shown, so that operation of the lever-connected linkage may be caused to function the clamping bar 6. Y
In Fig. 1 the web-released position of the `clamping bar 6 is shown, and in Fig.V 2 the web-clamping position of the clamping bar is shown. ,In order to cause the linkage to function s-o as to bring about these results,-I :provide fingers 25 and 26 extending from and attached to the respective shafts- 14` and 18.` These shafts are hooked at their lower ends for attachment of the ends of a coil tension spring 27. The effect of this-.spring risto draw. the ngers toward one another, thereby rocking the shafts 14 and 18, lifting levers 17 and rocker arms 13, and causing pins 11 to bear downwardly upon yokes 12 which cause bar 6 normally to clamp .the webs as shown in Fig. 2. Release of the webs is facilitated by vdownward movement of rod 24 through pre's- .100
sure uponits attached foot treadle, therebyy 4:14 extending between the sides 4 so that when -the shaft 14 is rotated the rocker arm` will pulling downwardly upon the yoked lever 20 at its end 22, causing it to pivot upon the pins 19 and bringing its ends 21 against shaft 14 so that the pins 19 will be drawn downwardly and therefore cause levers 17 to be drawn downwardly by pivoting on shaft l18 so that pins 16 thereof will operate in the slots of forked ends 15 of rocker arms 13. This causes rocker arms 13 to bring their pins 11 upwardly thereby lifting pins 10 and clamping bar G to the position shown in Fig. 1 so that the webs of paper are free to be released.
Cooperating with the mechanism l have just described is the paper cutter mechanism which is located forwardly of the frame carrying the web-clamping and releasing mechanism which has just been described. This paper cutter mechanism'is quite independent of the web-clamping and releasing mechanism, but, although cooperating therewith in the functioning of the machine, is designed to be operated alternately with the operation of the clamping and releasing mechanism, being operated, however, by hand instead of by foot as Vis the clamping and releasing mechanism through its treadle foot. This paper cutter mechanism is operated by a handle 28 mounted on a shaft 29 between plates 30 at the forward end of the machine frame. Upon shaft 29 at eachV side of the frame and v adjacent to the plates 30, is a gear segment 31 which meshes with the teeth of a rack 32 at each side of the frame and out of the path of travel of the paper webs as they are drawn through the machine between the racks. Connecting the'racks is a cutter bar or knife 33 extending across the websl and adapted to be -Y brought downwardly upon them upon lifting movement of handle 23. rlhe lower ends of the racks 32 are rounded to provide in eect cam-shaped surfaces 3i adapted to cooperatel with the face of a rocking bar 35 pivoted at a point 36 in each 'plate 30. This bar 35 carries a knife 37 which, when the racks 32 are moved downwardly, will be forced to occupy a position'such as shown in Fig. 2, against the back of knife 33 so that as the knife edges'move over each other in shearlike fashion, the webs projecting-beyond the contacting faces of the knives willbe out off. A short spring 33 bears agains the lower end of pivoted bar 35 to cause the bar normally to occupy the position shown in Fig. 1, but when the racks are moved downwardly, to'b'e compressed as shown in Fig. 2.
This'feature of' a pivoting knife-bar is an important feature of the invention in that it performs two functions which, among others, are important. First, such a pivoting bar permits of sufhcient clearance away from the webs as 'to permit the fingers of the operator grasping the webs for pulling them forwardly Vofl the aligning hooks 9. movement'of the lower knife away from contact with the upper knife 33, also causes the first-mentioned blade,
3.- Apparatus of the Second, the
operation of the machine to be much safer by preventing the lingers of the operator being cut or scratched in pulling the webs forwardly .or in even attempting to grasp the forward edges of the webs.
The lever 28 acts as a weight to keep the blades in their separated position.
Having thus described my invention, what I claim is:
l. Apparatusy of the kind described comprising ablade, a second blade'cooperating therewith, means including a manually operable pivoted lever for reciprocating the and means for pivotally mounting said second blade, said Vlast-mentionedmeans being adapted to c0- operate with the first-mentioned means to bring said second'blade into a functionally operative position each time the first mentioned blade is reciprocated.
2. Apparatus of the kind described comprising a pivoted lever, a pinion rotatable by `said lever,a rack meshing with said pinion,
a blade carried bysaid rack, a second blade cooperating with the first-mentioned blade,
and means movable with the second blade and adapted to cooperate with said rack to bringfsaid second' blade into afunctionally operative position. Y

Apparatus of the kind described comprising a movable blade, a second movable blade cooperating therewith, means for reciprocating the first-mentioned blade, the weight of said means normally holding the first-mentioned blade spaced from said secondvblade. and means constrained to move with said'second blade and adapted to covvoperate with the first-mentioned'means for bringing said second blade into a functionally operative position each time the first'A mentioned blade is reciprocated.
