TYPEWRITING MACHINE.

Application filed September This invention relates to typewriting machines7 and more particularly to apparatus for systematically feeding a continuous strip of paper over the platen and severing the same into desired lengths after a typing operation.

One of the objects of trie invention is to provide automatically eperating mechanism for systematically feeding successive lengths of a continuous strip of paper over a type-l writer platen which is under the control of the operator so that each succeeding length of paper can be quickly moved into `position on the platen for a typing operation.

Another object of my invention is 'to provide mechanism which will automatically control the movement of continuous strip of paper over a typewriter platen so 'that manual feeding of the paper before and after a typing operation is eliminated; thereby speeding up the outpilt of an onerator. Y n

A further object of my invention is to provide mechanism for automatically feeding similar successive lengths of paper from a roll into desired position on a typewriter platen; and for severing the preceding length of paper previously fed over the typewriter platen.

Another object of my invention resides in the mechanism l provide for gripping and feeding` desired lengths of `:Laper over a platen from a roll.

Another object of my invention is to provide a shearing mechanism which will be actuated the completion of each paper fcedin operation and which is adjustable to shear a continuous strip ofpaper into desired length which corresponds to the length of paper fed on each operation of the feeding mechanism.

'lo the above and other ends my invention consists in the features of construction, combinations of devices, and arrangements of parts hereinafter described and particularly pointed out in the claims.

Referring now to the drawings by characters of reference., 11 represents a conventional form of typewriting machine which is provided with a platen 12 over which paper is moved into position to receive character impressions. A suitable table 13 is provided to support the typewriting machine and the apparatus which forms the subject of this invention; and such table consists of legs 14; which are connected by braces 15 and a platform or top 16.

A pair of parallel spaced supporting brackets 17 extend transversely of the top 1G and are secured thereto adjacent the rear of the typewriting machine. The brackets 17 are provided on their inner upper edges with a raceway 1S which receive ball bearings 19 and a carriage 2O the sides of which extend adjacent the brackets and are provided with raceways 21 within which the bearings-1S) are seated. The carriage 2O is in the form of a cradle anc provided at opposite ends with roll carrying arms 22. The arms 22 at one end of the cradle are formed integrally therewith. while the arms at the other end of the cradle are pivotcd at 23 to the cradle and are removably secured at Q4 so as to permit movement thereof relative to the cradle. The shaft 25 of a roll of paper 2G is secured in bearing carried by the arms 22, and the roll can be readily renewed by swinging the pivoted arm 22 from the cradle on its pivot. It will be seen l'ha-t the brackets 17 are stationary on the table and that the cradle is free to move relative thereto transversely of the table. A lug 226 vextend upwardly therefrom.

projects from each side of the cradle and pins 27 are secured adjacent the ends of the brackets to provide sto-ps with which the lugs 226 engage to limit the movement of the cradle on the brackets. A suitable tension device 28 is secured upon the table beneath'the cradle, and a flexible member 29 extends therefrom and is secured to the cradle. Such tension device being formed to assist in the movement of the cradle so that the weight of the roll of paper and mechanism larried thereby will not create an undue drag on the typewriter platen shifting` mechanism with which the roll carrying cradle is connected.

The cradle 20 provides a support for a roll of paper, as previously described, and also carries a frame which supports the paper feeding and shearing mechanisms. A pair of standards 30 and 3l are secured to the cradle adjacent each end thereof and rlhe upper ends of the front standards terminate in housings 32 in which bearings 33 ext-end and the rear standards terminate in bearingsl 34 arranged in the same horizontal plane with the bearings The bearings 33 and 84 of each pair of standards are in alignment and rods 35 are carried thereby in parallel relation, and are secured rigidly with t-he frame standards 30 and 3l by set screws 36. The frame also includes transversely extending bars 58 which are secured across the tops of the bearings 34 and the housings The front standards 30 are secured to the movable platen carriage by a rigid connecting member 37, having its ends 38 secured to' the standards 30 by screws 39 and its central portion secured to the platen carriage by screws 40, as shown in Figs. l and 2 of the drawings. It will be seen that t-he cradle, frame and mechanism carried thereby will be moved integrally with the platen carriage, so that the paper and mechanism for feeding the same will be moved with the. platen when a line of typing is in progress.

he standards 30 and 3l are separated so that a desired width of paper can be moved therebetween. A roller 4l is mounted inter mediate the housings 32, and the paper web 52 from the roll 26 is passed over such roller iu its movement to the guide apron 42 secured to the platen (.farriage. A roller lil is secured intl-.rmedialc the housings 32, above and parallel to the roller 4l, and the paper extends thereover after passing around the platen from the guide apron. lVhen a roll of paper is inserted in the arms 22 carried by the cradle 20, the operator draws the free outer end of the paper over the roll 4l, then over the guide apron 42 and around the platen l2, and then back over the roller 43 whereupon gripping mechanism is applied.

The gripping mechanism carried by the frame secured upon the cradle 20, and consists of a reciprocable device which grips during feeding movement and releases during the return movement, and a relatively stationary device which grips the paper during the return movement of the reci procable feeding device and releases during the feeding operation thereof.

The feeding gripper mechanism is slidably mounted upon. the parallel. rods and is arranged to move a length of paper over the platen during` each 'teething oi'imal'ion. Such. paper feeding grippingl device is comprised of a pair of relatively reeiprocable liars 44 and 45 which extend intermediate the shafts and are reciprocalily mounted relative thereto. The lower har 4lA is provided with a housing` 4G at caca end having apertures 47 therein through which the, shafts 35 extend. The upper gripper bar 45 is of less width than the lower gripper bar and is arranged in alignment. therewith. The ends 4S of the upper bar are enlarged and are provided with apertures 4D lthrough which screws 50 extend and are screwed into the lower griliper bar. The upper bar is vertically reciproeable relative to the lower bar and the screws, and coil springs 5l are provided round the screws, within the apertures 49, and bear against the heacs of the screws and the upper bar to normally create suflicient tension to hold the upper har tightly against the lower bar. Rubber strips 52 are secured around the bars 44 and 45, in spaced relation, to prevent slippage of paper to be secured between the bars.

As previously related, the bar 45 will be normally pressed tightly against the bar 44 by the springs 5l to clamp the web ot' paper therebetween, and cam mechanism is provided to raise the upper bar at the completion of the feeding' movements and during the return movement rto the succeeding gripping and feeding position. The undeil face of each end 48 of the upper bar meniber is slotted parallel with the. rods 235 exteriorly of and adjacent the screws 5l). and apin 5l extends transversely across such slots 52. A member 5&3 extends through each of the slots 52 and is provided with an upper cam face which ezignges with the pins 5l therein, while the lower face ol lhe cam member and bears upon the upper face ol' the lower bar member 44. The am members are ol greater length than the width of he liars 44 and 45 and their ends are provideifl with depending flanges 54 to limit the endwise movement of the cam members in the slots is .straight through their engagement with the :trent and.. rear dge of the lower bar 44. The

members are slidably mounted in the slots 52, and by moving the members into a forw rd or rear position with respect to the, bars ll and 45, the upper cam surfaces will lllt) lill) l of the feeding` movement of the bars.

engage with the pins 51 and raise the upper bar 45 againstthe action of the springs, when in one position or will permit the springs to press the upper bar tightly against the lower bar, when in another position.

The cam members 53 will be automatically shifted in the slots 52 against the pins 51, and collars 55 are adjustably secured upon one end of the rods 35 by set screws 56, while arms 57 are secured to the frame member 58 extending intermediate and secured to the housings 34C. As the bars ill and Ll5 move forwardly the forward ends of the members 53 will strike the depending portion of the arms 57, and will be stopped prior to the completion of the forward moven'ient of lthe bars, so that when the bars reach the limit of their forward reciprocation the cani members will be in position re yive to the pins 51 to allow the springs clamp the paper extending from the roller 41B against the bar 141-.. As the gripper bars are nfioved rearwardly in a horizontally plane, the erns remain in their last position until thcv mike the collars 55, and therefore th n will grip, and pull the paper therewith the i istance of their travel. The collars arranged so that the cani members 'wil engage therewith just prior to the completion En gagement of the cam members with the collars 55 will shift their relation with the pins 51, as the bars continue to move a short distance, and due to such movement of the pins 51 relative to the cam members, the upper bar dll will be raised releasing the paper. The bars will remain separated as they move to t-he forward position to grip another length of paper prior to a feeding movement, as the cam members retain their last position until they strike the arms 57 at the forward end of the frame.

The feeding` gripping members 114 and l5 are reciprocated by mechanism which is associated with a motor 59 which is carried by a platforn'i G0 secured to the table 13. One end of the platform is pivoted to the table at G1 while the other end of platform carried by a bolt 62 (impendingv from the vtop of the table. A belt 63 extends to reduction driving gearing G1 and the belt is vtightened by a. justmcidi of nuts (55 which secure the end of the platform with the bolt 62. The reduction gearing' extends intermediate the shaft GG driven by the belt and a driven shaft G7 and suitable clutch mechanism is provided for connecting` or disconnectingg` the mechanism intermediate the shafts 66 and ('37. The clutch mechanism 70 of `the type disclosed in my co-pending application Ser. No, 54,000 filed August 28, 1925, can be operated by a rod 68 connected to a pivotally operated treadle 69, and can be pressed down ing` after each actuation as it will move back automatically to inoperative driving` relation. Said clutch, as best shown in Fig. 11 of the drawings, preferably comprisesv a gearcasing 611 having a projecting portion 151, a shaft 152 journalled in the casing, an internal ring gear 153 keyed to one end of the shaft and a clutch element 154 keyed to the other end of the shaft and disposed in the recess 155 of the'projecting` portion 151. A scond clutch element 156 is keyed to a short shaft 157 which shaft is journalled in an end wall 158 of the gear casing. The side of the projecting portion of the gear casing is apertured at 159 into which dog` 1GO projects and is adapted to interconnect the clutch elements 1511 and 155. 151 may be oscillated by the dog' 160 to etlect a connection between the clutch elements 151 and 156 or to oscillate the same in an opposite direction to disconnect the clutch ele-- ments. The clutch is of such a type that it automatically disconnect the power ve upon each reciprocation of the feeding lll and L15.

A lercr 71 ii pivotally mounted at its lower end upon a shaft 72 mounted in a bracket 7l-l secured upon the table 13. The lever 71 extends adjacent one end of the shaft (S7 and is pivoted in the same vertical plane therewith. An eccentric arm 7st is secu l toghe end of shaft 67 and a bearing is adjustably secured to the eccentric arm by the bolt 76. The upper end of the lever 71 is pivotally connected to one end of a link 77, while the other end of such link is loosely mounted on the shaft 78. The shaft 7 8 eirtends through apertures 79 in the housings /116 at the encs of the lower gripper bar and secured therewith by the set screws 80.

lt will be seen that rotation of the shaft 57 will cause the bearing;l 75 to rotate and being slidably mounted in the slot in the lever 71, it will rock or oscillate the lever 71 on its pivot 72, and such .movement of the lever 71 will be transmitted to the link 77 which will reciprocate the gripping members through its connection with the-shaft 7S. By adj usting the bolt 7 6 the bearing 75 will be moved relative to the axis of the rotation of the shaft 57, and the rocking` movement of the lever 71 can thus be varied to regulate the reciprocal movement transmitted to the feeding; gripping ba'rs "d and f thereby regulating the length of paper fed from the roll duringthc feeding operation.

rlhis machine is adapted in one of its uses to be utilized for filling in the names and addresses on form letters and the like where blank lines are to be inserted by the operator of a typewriter, and in such use the reciprocatiiig` gripping bars are operated the desired distance by the lever 71 stroke so as to feed the paper in desired relation on the to transmit power and will be self-releas-platen for typing by the operator of the Said pin typewriter. l.When more than one line is to be typed the platen can be rotated manually in the usual manner and the slack in the web 82 will lie intermediate the gripping bars le and 15 and the platen, so that it will not intertere with the succeeding` feeding operation.

It will be seen that the link 77 remains stationary relative to the transverse movement oi? the cradle and the paper grippingl niechanism fhile in any ot its transwrsely adjusted pos Lions. llairs oit paper supporting` strips 8l, preferably :termed ot ribbon metal, extend longitudinally o1" the supportinn` frame carried by the cradle and are secured at one end to the innlerside el: the

liorward frame member 58 and at the other end to the under side of the upper relatively stationary gripper member The metal strips S1 extend intermediate the rubber strips a2 on the bars 4l and l5 and as a. support- 'lfor the web of paper which is moved over the trame. 'lhe bar 'aL-lprovided with extended bearing portieraI 83, adjacent the ends oili the apertures 117 therein, through which the rods extend. To insure that the bar 44 will not bind at either end on the rods 35 during reciprocation7 equalizing mechanism is provided. A pulley Slt is secured to each of the trame standards 31, and a coiled tension spring extends around each pulley. rthe springs are secured at one end to the enlarged ends 116 ol' the bar 4d by screws 80 and at the other end to the trout standards 30 by screws 87. The tension ol the springs at opposite sides oit the bar 14 will assist in maintaining the bar so that it will slide freely on the rods l5 when reeiprocated.

Gripper members 82 and 88 are mounted upon the rods 35 and are adjustable thereupon so that they can be positioned adjacent the rcar position oli the varial'ile reciprocablo movement oli the eedin `Ljrippers 4d and rlhe ej ppers and 88 are arranged to be autmnatically actuated to ,fri-ip the web ot paper, while the reciprocating feeding grippers are released, and thus secure the web of paper during the return movement ot the liecdino' `e'rippcrs.

The lower ,gripper bar 8S extends substantially parallel 'with the gripper bar 114K, inlcrmeiliale lhe rods l5 pli the trame. and secured at ils ends by screws 0:2 upon bearingmenilfers tlf). 'l`he bearing men'ibers 80 are provided with apcrlurestll) through which tlu` rods 35 extend and set screws 01 are associated therewith to secure such bearing nicinbers in desired longitudinal position on the rods. The upper stationary `gripper bar S2 .lies parallel with the lower bar SS and is supported in such relation by toggle linlis 93 adjacent each end. rlhe toggle links are secured at one end to the iii-ont side o1 the bar S8 by screws 9st and at the other end to the H ln front side oit' the upper bar 82 by screws 95. The bar 82 is provided adjacent each end with vertically extending` apertures through which bolts 00 extend, such bolts being?r screwed into the lower bar member 88. The upper bar gripper 82 is reciprocable vertically and coil springs 97 are provided aroimd the bolts 0G and bear at their ends against the upper side of the upper gripper member S2 und the head of the bolts, thus creatingv a. tension sul'licient to normally noove the upper grippingv member S2 tightly aoainst the lower grippiimmember 8o.

One of the toggle members 03 terminates in an extension 97 which extends beyond the gripper bars S2 and 08. A bell cranl: member 9S is pivoted upon the housing S0 beneath the extension 97 ot the toggle member, by the screw 99, and ay cam Yface is provided upon the bell crank 98 to actuate the toggles by engagement with the toggle extension 97. A rod 101 connected to they bell cranli and extends forwardly oit.' the supportingl iframe substantially parallel with the rod 35 and is secured adjacent the forward end of the frame in a collar 102, which slidably mounted upon one et the rods 35, by a set screw 103. The cam 100 and the toggle extension 97 are so related that when the cellar 102 to which the connection 101 is secured is in its forward sliding' position, the cam will engage the toggle extension and operate it to raise the upper bar gripping;l member 82 from the lower gripping member SS. lVhen the reciprocating;- gripping members move forvardly the stationary grippers will clamp the web oit paper therebetween, and as the bearing strikes the collar 102 it will move it therewith and also the connection 101 which in turn will swing the bell crank 08 and cause the cam 100 to engage and raise the projectirmv end Sfti ot the toggle, which will raise the upper bar member 82 therewith. It will he seen that the mechanism described 'tor raising;` they gripper 82 is timed so that it operates at the completion of the forward movement oi the reciprocating grippcrs, and simultaneously with the mm'einent oli the cams 53 which el'liects `-@ripping` oli the paper web by the reciprocating gripping' mechanism as previously described. The am 100 and the tir Vlr remain in position ',"ll'ecleil by `lic tor ward movement o'l the collar 102 during the rearward. movement oli the reciprocating mechanism, and a pawl 101 secured lo the side of enlarged end 46 of the lower reciprocating gripper 4l is arranged to engr 1 the bell crank and swingv il' so that the cam 100 is released sufficiently to permit the springs 97 to force the upper gripper bar 82 tightly against the web ot paper, where it remainsy (lining` the return movement of' the reciproeating` gripper members and until the collar 102 is again moved forwardly.

lill

It will thus be seen that the stationary and reciprocating gripping mechanism will grip the paper alternately, so that it is held by one or the other at all times. It will also be seen that the reciprocating grippers will engage the web of paper, move it a desired length, usually the length of a sheet rto be later severed, with the stationary grippe-rs released, whereupon the stationair grippers engage the web of paper adjacent the point engaged and moved by the reciprocating grippers, and hold the paper while the reciprocating grippcrs move forwardly to engage the succeeding length of the web to be moved. Then similar letters are printed upon a continuous roll of paper, the paper is first positioned so that the blank address and names to be typed will be in the proper relation on the platen of the typewriting machine, and the lever 71 set with the bearing T so that the stroke of the reciprocating grippers will be the length of the sheet of the letters to be severed. The stationary grippers are then set to lie adjacent the rcciprocating grippers at the completion of their feeding stroke and the collar is set in proper relation to actuate the cams at the proper time.

A shearing mechanism is actuated by` the mechanism for reciprocating the feeding g-rippers, and is timed in its action to sever the continuous web of paper projecting` at the rear of stationary grippersafter each feeding operation.

Abell crank 110 is pivotally secured to the under side of the housing- 89, in api-ane below thc bell crank 98, by a stud' 111. A wire connection 112-is secured at one end't'o one arm of the bell crank 110 and extends `parallel with the connection 101 along one side of the movable frame and extends through a. plate 118 secured to the side of one of the 'frame standards 30hy astud'llt. A collar 115 is secured by set screws 116 to the wire 112 and provides an abutment with which a downturned flange 11? of 'the paw?. mr-inibcr d A stiff wire connection 118 extends across the rear end of the fram a and is connected totheother arm of the bell crank 110.

A knife member isk pivota'lly secured by a stud 120 to the rear side of the lower stationary gripper bar 88 and adjacent one end thereof. The pivoted end 121 of the knife member is angular in form and the wire 118 secured to the lower end thereof'. he knife membcris preferably integral in form and includes a cutting lade 119 and an upwardly extending army 122. The blade is pivotally connected with the stationary gripper members 82 and 88 so that it can be moved relative to the rear faces thereof and cooperates therewith to shearthe web of paper transversely at the point where it projects rearwardly from the gripping memrthat it can be actuated by the next return bers. A coil spring 123 is secured at one end to the upper end of the knife arm 122 and at other end to one of the members 57 by a screw 124, and' normally maintains the knife blade in a position above the stationary gripping members with which it cooperates.

lVhen t-he reciprocating gripper members 44 and 45 approach their forward position, the flange 117 of the pawl 104 secured with the gripper bar 44: will engage the collar 115 and move it therewith. The movement of the collar towardr the front of the machine will move the wire connection 112 therewith and will swing the bell crank 11() on' its pivot, thereby opera-ting the wire connection 118 to move the knife blade downwardly, against the tension of the spring 123, across the rear end adjacent faces of the 4gripping members 82 and 88 which are holding` the paper and thus shear the web of paper projecting beyond the stationary gripping members.` It will be seen that this shearingv operation is arranged to be automatically performed by the movement of the reciprocating gripping member 44", and that it is timed to operate as the gripping` member 44 isreturning ton a forward position and while the paper-is gripped between the bars 82 and 88.

The bell crank when swung tio actuate. the knife passes under a stop'me'mber 125 which is provided with a lower angular edge and is slidably secured to the housing 89 by studs 126 which extend through a vertically arranged slot 127 formed therein. A spring 128 is coiled around a stud 129 screwed into the side of one of the bearings311` and bea-'rs against the topfof the stop" member 125 creating a dow'nii*ardV tension' thereupon; An arm of the bell crank 110 will force the stop member 125 upwardly when it is swung by the forvmrd move'n'ient of the wire 112 to' operate the knife, and after it passes thereunder, the spring will` force 'the stop member to its lower position so that the bell crank is prevented from returning 'to its former position.- The stoptmember is provided with a pin 129 extending from' one side thereof, and the pawl` member 1011 provided with an angular face 180 which engages under the pin and raises the stop member when the pawl moves rearwardly withthe reciprocat-l ing gripping members, thereby releasing the bell crank 1'10 so that' the spring 123 will move the knife to its uppermost position, so

l2() movement of the reciprocatingv gripping mechanism-` The knife and its operating mechanism are carried by the transversely movable-frame on which. the gripping and feeding mechanism are supported, and that the operation of the knife is automatic and timed to operate after each paper feeding operation.

Mechanismis provided to eng-age the roll of paper after each feeding operation so that 130 ra trhet 134-.

there will be no slack to interfere with the feeding operations. A bell crank lever 130 yis pivoted to one of the standards 30 of the frame by the stud 131 and the lower leg 132 thereof is provided with av pawl 133 which arranged to engage with the teeth of a ratchet 134- secured to the shaft supporting the roll of paper. An upwardly extending arm. 137 is pivotally secured at its lower end upon a shaft 138 which is secured in brackets 139 extending from the base of one et the standards 31. The arm 132 is held in contact with one side of the arm 137 by a spring 1&0 which is :connected at its ends to such arms, and the upper end of the arm 137 is bent and has a collar 141 adjustably secured thereon by a se" screw 142. The collar eX- tends into the path traversed by the reciprocating gripper members, and a cam member 143 is secured to the shaft 78 beneath the gripping member 44 to engage with the collar 141 during a portion of its reciproeable travel and thereby rock the arm 137 to allow the lever 132 to drop to a position where the pawl 133 will engage with the ratchet 134 and prevent rotation of the roll oft' paper. As the reciprocating` gripping members 44 and 45 move. forwardly, the shaft 78 will engage the upper end of the arm 135 of the bell crank 130 and will carry it therewith and thus rock the bell crank so that the pawl is raised from the ratchet- 1341. thus permitting the paper to unroll as the gripping members pull a length of paper therewith during their feeding movement. As the gripping bar 441- approaches the rear position, the cam member 143 will engage the collar 142 on the arm 137 and swing ythe arm on its pivot in a direction to allow the pawl 133 of arm 132 to engage the The collar is adjustable so that it. can be properly positioned relative to the vmovement of thc shaft 7S, so as to drop the pawl into engagement with the ratchet immediately upon the completion ot each paper :feeding operation, and thus prevent the momentum of the feed operation from unwinding` the paper from the roll intermediate the feeding operations. The spring 1li-O will retain the pawl in engagement with the ratchet until the arm 135 is again rocked by the engagement therewith of the shaft 73 just prior to each feeding operation. During the return movement of the bar gripper L14 the shaft 7S and cam 145 will clear the collar 141. It will be seen that the roll controlling mechanism will operate autoniaticall;7 to secure the roll intermediate the feeding operations, and to release the roll during the feeding operations.

Assuming that the motor is running, the operator can press down on the treadle 69 which will operate the clutch 70 to connect the speed reduction gearing to drive the lever 71, the clutch being arranged to oscillate the lever 71 one full movement whereupon it is self releasing. The full movement ot the lever 71 will reciprocate the grippers fill and 115 to feed a length of paper from over the typewriting machine platen whereupon the paper web remains stationary until the operator again throws in the clutch. l3ntween the feeding operations the operator can type upon the portion of the paper on the platen, and the paper can be manually fed over the platen if typing is desired on successive lines.

It will be seen that one operation of the lcver 71 will automatically feed the paper a definite length from the roll, and that the reciprocating gripping members will automatically actuate the stationary lgrippers to open and close, will operate the knife, and the roll control mechanism. .lt will also be seen that the various mechanisms are adjustable so that the web of paper can be moved different lengths and can be sheared in such lengths. Nith the mechanism described the operator is enable to materially increase the output of form letters and the lil-Ie, over the present method of inserting separate sheets and positioning and fcci'ling' them manually.

Various changes can be made in theI details of construction, and their arrangement therein described without departing vfrom the spirit of my invention and the scope ot what claimed.

That I claim is 1.
