EDWARD FRANK KUNATH, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO UNDERWOOD TYPEWRITER COMPANY. 0F NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

STENCILING-MACI-IINE.

T 0 all whom fit may concern:

Be it known that I, EDWARD FRANK KUNA'ri-I, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented cert-ain new and useful Improvements in Stenciling-lachines, of which the following is a specification.

This invention relates to that class of stenciling machines in which a waxed paper typewritten stencil is placed upon a holder, which is made of perforated sheet metal, ink being supplied through the perforations to the stencil, and means being provided to press the paper against the stencil. The stencil-holder is usually in the form of a revolvingl cylinder, and the pressing device is usually a soft rubber roll, as set forth in Letters Patent No. 824,695, of June 26, 1906.

Heretofore it has been the practice to insert paper sheets one at a time in the machine, to be stenciled, but this is found to retard the speed of operation if done by hand, or to add unduly to the colnplication and eX- pense of the machine if done by automatic means.

The object of my invention is to provide simple, inexpensive and practicable means for producing stenciled sheets of any desired length within the usual limits, and especially to enable t-he stenciled sheets to be turned out at great speed. To this end, I provide for mounting a roll or web of paper of suitable width upon the stenciling machine, and leading the web between the stencil cylinder and the pressure roll, thus making it practicable to obtain an extraordinary speed of stenciling` the paper, and correspondingly to reduce the cost of the stenciled sheets, and also to minimize the delay in obtaining' the same, which is often a matter of great importance.

The web is fed forward by the pressure of the roll against the stencil cylinder. To vary the extent of the feed of the web during each revolution of the stencil cylinder, I arrange to cast olf or release said roll for a greater or less interval during each revolution of the cylinder', so that the extent to which the web is advanced is considerably less than the circumferential dimension of the cylinder. I also arrange to sever the web once in each cylinder revolution, to produce Specification of Letters Patent.

Application filed August 19, 1907.

a succession of similar stenciled sheets, which may be of greater or less length, according to the adjustment of the mechanism; the lengt-h of the severed sheet agreeing with the extent to which the web is advanced at each stenciling operation.

The web feeding and severing mechanisms are preferably operated by springs which are constantly wound during the revolution of the stencil cylinder, thereby distributing the work throughout the revolution of the cylinder, and avoiding undue resistance to its revolution at any point. The, actions of the springs are controlled by trips or latches, and are very prompt, so that accuracy of feeding and severing the web is secured. Said latches are preferably operated by means of tappets, which are adjustable around the cylinder to regulate or time their operations as may be desired. The range of adjustment of the web-feeding means may be very great, so that either very short or very long sheets may be severed from the web; and preferably means are provided for adjusting the severing knife or blade bodily toward or away from the cylinder, thereby making it convenient to locate the cut at any desired point with reference to the stenciled matter on the web, whether the severed sheet is long or short.

In the accompanying drawings, Figure 1 is a side elevation of a stenciling machine constructed in accordance with my invention the stenciling and web-feeding mechanism being shown in working position and the severing-blade as elevated. Fig. 2 is a perspective view of the principal moving parts, showing them in normal positions in full lines, and also showing the operation of the parts by means of dotted lines. Fig. 3 is a plan of the machine. Fig. 4 is an elevation of the end of the machine at which the stencil cylinder is mounted, the web-holder being omitted. Fig. 5 is a sectional elevation taken longitudinally of the machine, and showing the parts in the same posit-ion, as at Fig. l. Fig. shows some of the parts seen at Fig. 5, but showing the pressure roll released from the cylinder. Fig. T is a perspective view of the paper-roll end of the machine, illustrating the roll mounted so that it is dragged over the edge of the paper-shelf, to straighten the web. Fig. 8 is a detail of .=upon a base. runs upon. rolls; two of which-areseenat -6, "this end of the drum being open to receive means to release the web-feeding and severing mechanisms during the vrevolving of the stencil cylinder for inking, etc. 'Fig. 9 is a diagram to illustrate a. method of interleav- -ing the freshly -stenciled sheets'with lot-her sheets yto -prevent--olfsetof vink "'froin one stenciled sheet to another stenciled sheet.

The stencil cylinder 1, which as usual is in the form of a hollow drum whose periphery is formed offa sheet of perforated metal2, Fig. 5, is mounted at one end by. .means ofa driving-shaft 3 upon a standard 4L erected At the other. end; the drum;

thev ink. The rolls are carried luponstand-i -ards finas usual. The cylinder may bef-ro-l tated by means of a 4handle 7, butl prefer to; employ a pulley 8 `seen on the driving-shaftT 3,11`ig. at. The paper or. web .in the form-of a roll 9 ismounted -upon a core.10 which is looselyournaled upoiranaxle l1 detachably secured in the outer endof a shelf 12. The web is passed' forwardly between guides 13 for its 'side edges,.and l,through a throat comprising lower vand upperv plates,f the=lower plate. 141 being practically. a continuationof the shelf 12, and. .the upper plate 15 curving around the'wlower portion of the cylinder- 1. Through this .throat .the .web passes into the bite of the cylinder 1 and-a softrubber pressure rollA 16 which presses. the-web against .the inked stencil or waxed sheet mounted .in

the usual manner upon vthe periphery ofthe 4cylinder 1.

.The usual .strippingfingers.17,-.are illustrated in extending` from the vplate 1li-alongsideA of .the ends ofthe rolls 16: and back- .wardly, but these strippers may be omitted in some cases, as .also-'may be ftheupper .throatlplate 15. rl`he rolla16 las usual-is mounted by anaxle 18 in arpair of.I arms 19 yhinged at 2O Vuponv the fran'ieworkand. connected at their forward ends by an equilibrating .bar 21to the middle ofwhichan upwardx-pressure is applied,.whereby the roll is caused Vto press throughout.evenly up against the cylinder as set forth inPatent No. 829,531, of August 28, 1906. tFrom the stencil cylinder, the stencil yweb advances overa table 22 to the web-severing mechanisn1,aswill. presentlyA be explained. The Abar 21 and the-roll 16 arezheld up by means of a link 23,pivoted;at its upper end to said bar midway of the length of the latter,-and pivoted `at its lower end upon-.a wrist 24 .which projects from a revoluble barrel 25 mounted Aupon one end of a shaft 26 and carrying a .winding spring 27. 'The barrel 25 is lprevented: from turning by means of a latch work. As will be .seen atFiga, .thelatch 28 formsea positive support for .t-hewrist 24E,

landzhence for the link 23, the bar 21,and the l pressure roll 16, so that the Vlatter cannot fdrop, butfis held' up to :its .work ofV pressing' up the web against the stencil carrying cylinder 1. The spring 27, acting through the barrel'25,^also tends to carry vdown the wrist '24 4in' the direction ofthe arrow. A1t will therefore be seen that by moving the latch '28"'forwardly or to the left at Fig. 5,7the wrist 24 will be released to permit the withdrawal of' the roll 16 from the stencil'cyljinder: l.

The mechanism which releases the latch 23 comprises :marin-30linedV upon the other Mendof theshafft 29 from said-latch, and a .flink-31-extending rearwardly from said arm tothe. lower end of an 1upright..lever ,32, Iwhich -is pivoted between itsends at'33 upon ra part of they framework. The upper end of .this -lever carries a pawl-34t1which.normally stands in the path of a tappet-35 carried ifupon the cylinderl, Ywhereby the lever is .moved -to .the position seen .in dotted lines at Fig.2 and the pawl 28.is-1noved to the position seen atY Figa-6. Y

Themovementof the roll 16 from the F ig. 5 to the. Fig. '6 positionv is caused Apartly by v`the action ofthe spring 27,-and the :latter insures. the swingingv of the .wrist 21into engagement with a latch y36 which rest-rains the kfurther action-of the spring,-and insures fthecontinuedseparation of the roll 16 from vthe cylinderl. Duringsuch separation the web. lies .motionless upon the shelf-14 vand bed 22, while the cylinderf 1 continues to` -frei volve. -Before thewebaagain.advances. the web-severing..mechanism operates in a man- .,ner. presently to be explained. -The spring 27 is incessantly wound by means ofiagear 37 Aupon .the driving shaft 3, saidgear meshing .witha bevellgear which is viXed upon one end of a .diagonal shaft 39,'a bevelgear 46.011,. 4thewlower. end of said shaft meshing with. al bevel gear'tlnpon the spring shaft 26. Said shaftV 26 -is Ajournaled atfone end in the lower vpart Aof the. standard 4,-and near .the other end in an upstanding ar1nt2 erected Eupon the base, F ig t. VIt will'further be .luider-stood that-when .the latch `36 is moved rearwardly or.to the right atfFig. 5,l the wrist 21 will againi be released and the spring 27 permitted. to turn .the spring-barrel and itssaid wrist. .to the Fig. 5` position. Such release ofthe latch 36 is effected by means of a second tappet tfwhichis formed Eto escape .the pawl 34h-but to engage a second pawl 114.. pivoted 4upon the top of v4a lever 45, which is Afulcrumed tt-46 vupon theV .frameworkand connected by a linkia to a rocker ar1n4l8, which is-secured upon one end of a tubular shaft Yt9v through which the rocksha-ft29 extendsendwise. Said-V latch 36 is .tixedupon` the other end of said tubular shaft 49. After the tappet 35, moving inthe Ldireetionof the arrowI at F ig.'2, has operated the; pawl Baand- .thelatch 28 to release the Y roll 16, the second tappet 43 moves the pawl 44 with its lever 45 to the dotted line position at Fig. 2, thereby rocking the latch 46 to the dotted line position at said figure, thereby releasing the wrist 24, which permits the roll-restoring operation of the spring 27 already described.

The link 23 is preferably adjustable as to length, se as to vary the pressure of the roll 16 as may be desired, said link comprising two parts 23 and 23a connected by a turnbuckle 23D, the turning of which lengthens or shortens the link, to increase or diminish the upper pressure of roll 16 against the bottom of the stencil cylinder. Springs 50 and 51 restoie the levers 32 and 45 to normal positions together with their respective latches 28 and 36. The pawls 34 and 44 are beveled and pivoted on said levers to permit reverse rotation of the cylinder 1, said springs 50 and 51 being connected to said pawls in a manner to restore them as 'well as the levers to normal `positions. The

pivots of the pawls are marked 52 and 53.

1t will be seen at Figs. 2, 3 and 4 that the lever 45 or its pawl 44 stands alongside of the lever 32 or pawl 34, the tappet 35 being too short to reach the pawl 44. The tappet 43 is in the shape of a crank, seen best at Fig. 3, the same being cranked to avoid the pawl 34, that is, to bring the striking portion of the tappet nearer' the axis of the cylinder than is the tip of said pawl 34; while said tappet 43 extends far enough out from the cylinder to strike the pawl 44. Said tappets are insertible in sockets or seats 54 in the form of perforations d rilled in the end of the stencil cylinder 1.

The roll releasing tappet 35 may be adjusted to the various points for nearly the entire circumference of the cylinder. The range of adjustmentv of the roll-restoring tappet 43 may not be so great, and transverse seats or recesses may be formed in the edge of the cylinder to lock the crank portion 43a of the tappet against accidental revolution; and any usual means may be provided for securing each of said tappets where adjusted around the cylinder. The duration of the feed of the web at each revolution of the cylinder, and consequently the length of the sheet to bc cut off, is determined by the distance between the roll-releasing tappet and the roll-restoring tappct 1t will also be understood that by adjusting said tappets the operation of the feed controlling mechanism may be timed to occur at different portions of the revolution of the cylinder, even though the extent of the advance movement of the web is the same; for instance, if the tappet 43 be placed in the first socket at Fig. 2, and the tappet 35 correspondingly shifted, it will cause the feeding movement to occur at a different portion of the cylinder revolution, but without changing the length of such feeding movement or the length of the sheet to be cut off from the web.

In order to prevent false feedino' movement of the web at the release ofthe feeding roll 16, 1 provide spring-fingers 56 to bear upon the side edges of the web between the spool and the cylinder 1. These press the paper down upon plates 57 formed upon the guides 13 and resting upon the shelf 12. Each guide with its fingers 56 and plate 57 is adjustable toward and away from theother and may be secured by a thumb screw 58. By means of the friction fingers or brakes 56, the stretch of the web between the spool and the cylinder is instantly checked, when the pull of the roll 16 thereon ceases. This insures accurate spacing of the stencils upon the web, and also accurate cutting of the web into sheets. The shelf 12 is releasably caught upon pins 59 by means of hooks 60, and may be detached from the machine together with the guides 13 and the paper roll, which is mounted upon the front end of said shelf.

rlhe web is severed into sheets by means of a transverse knife blade 61 mounted upon a bar 62, and normally elevated by means of arms 63 which hang from a rod 64 carried upon the rear ends of a pair of rock arms 65, which extend forwardly from a rock shaft 66. It is perceived that when the shaft 66 is caused to rock, the rock arms 65 descend, and force down the knife frame 62, 63 to sever the web 9a, which is indicated by a dotted line. A coperating knife-blade 67 is fixed upon the rear end of a bed or table 68, and a spring 69 holds the blade 61 against said blade 67.

The knife operating rockshaft 66 extends across the machine, and is journaled in a pair of posts 70 erected upon the bed 68 one at each side of the ixed plate 22. The bed 68 is mounted upon ways 71 provided upon side bars 72 of the framework. The bed may be conveniently adjusted along said ways by means of a hand wheel 73, shaft 74, and pinion 75, said shaft mounted in the side bars 72, and said pinion meshing with a rack 76 provided upon the under side of the adjustable bed or table 68. By turning the hand wheel 73, said bed 68, together with the posts 70 and the web-severing mechanism, may be adjusted toward or away from the stencil cylinder 1, thereby to adjust the line of cut with reference to the repeated stencils that have been inked upon the web. A spring pin 77 may engage a ratchet wheel 78 lixed upon the shaft 74 to hold the bed where adjusted, although this provision may be omitted in some cases. rFhe plate or shelf 22 immediately overlies the bed 68, and the two taken together form a continuous extensible table for the web to travel over. At the rear end of the bed 68 is provided a plate 79 which coperates with 1 the :top the' ibed tof .formia throatv through which `the web passes, said throat being very close to the stationary; knife -blade 67, v so c as .to pprevent buckling of the -web i where I 5 4.itl is severed. .At thesidesl of: the tablet 68 .eadjaeent to said 'throat-are 4guides 80 forI .theside edgesof thewv'eb, said-guides adjustdotted ilines. llhe spring-82 being vrno longer restrained, effects -an entire -revolution 4of the-spring barrel- 83,and yby means-vof the crank 98-on said barrel, the link 97, and 'the arm A96,= the rocking frame 65,66 is -causedto swing fdownf and--up,an'd the blade l61 to sever the web,- the latterfbeingmotionless.

The two -websare severed simultaneously, and the stenciled sheets 120 alternate-with the unstenl yciled sheets 121-in the vdelivered pile. The 125 blank sheets shouldi be 'fof soft or absorbent material, and f are inexpensive. 'By this means oifsetof ink-from one stencile'd sheet toanother is avoided; i
