To all ivho'm it may concern;

" Be it known that l, CLARENCE M. CRnWs. a citizen of the United States, residing in 'ifaBrooklyn Borough, in the county of Kings.

city and State of New York, have invented pertain new and useful Improvements in Typewriting "Machines, of which the folfljlowing is a specification.

' This invention relates to manifolding w Fnpon superposed plies of work-webs in typewritin machines. For example, the fimprovernents. are adapted for doing conftinuous billing work, and also for performing, upon continuous work-webs, other classes of manifold work, especially where the number oi carbon copies required for successive writings varies.

@ne of the objects is to adapt standard front-strike typewriting machines to per- Q-form web manifolding by simpler means send more easily than heretofore.

. Relatively short carbon-sheets are interleaved with the continuous work-webs, to

enable a form which is usually printed on ;the webs to be typed and manii olded. A

relative shifting between the set of carbonsheets and the web-plies is efiected in a ":novel manner after the typing of every form. The arrangement of the web in the typewriting machine is novel. Instead of iiollowing the usual manner of introducing lthe webs around the platen and up in front thereof to be typed upon, the method is followed, according to this invention, of inftroducing the pack of web-plies with the interleaved carbons" forwardly over the top f the platen and down in front bacltwardly beneath the same. The down- '-;ward and backward movement of the web brings the same to position to receive the first line oi t pe-impressions. Thereupon 1 the usual teed-rolls (released during the insertion of the web) are caused to clamp the t web upon the bottom of the platen, and the typing oi the leading form proceeds line i by line. it will be understood that the typing begins with the bottom form on the web, instead of with the loading or top form as F heretofore. hen the typing of the form is completed, the pack. of webs and carbons .-is advanced around piaten until the 'paclr the whereupon the thereof and of the webs clear of the carbons, while the carbons are then in position for the manifolding of the next torm above. At this juncture, the typed form or forms are sev erd from the web, this being conveniently done by means of a knife, which is placed in a suitable position at the front of the platen.

Then the bottom end of the web with the carbons is inserted downwardly and backwardly around the platen until the fresh form thereon isin position to receive the first line as typing, whereupon the cycle of operations is repeated.

From the front of the platen rises an introductory paper-table of considerable height, and over this table the large number of continuous work-webs (preferably as man as can be typed at a single writing) is t rust or introduced bottom end first down to the front of the platen, and thence around under the platen to the rear. The.

webs (which may be either loose or fanltolded) may have forms printed upon them or they may be blank according to the nature of the work, and they may be fed from any suitable source ot supply at the rear of the machine, such as web-reels or set of individual web-packs. @ne of the differences over the prior art is that the webs are inserted in the machine bottom end first, so that the form at the top oi the web is the last one to be typed.

The interleaving carbons are carried by a carbon-carrier, preferably oi? flexible sheet material, which is guided down to front of the platen by the 'front'paper-tahle, and may be conveniently fed around platen with the work-webs. The carbons are attached attheir upper ends to the carbon carrier by means of carbon-holding strips or blades. The blades are superposed on. the carrier, so that the carhon carrier and hence the supporting; ntroductory table will not he required to extend to an unnecessary heignt alcove toe platen.

in the initial position the first form or stretch of the work-webs, tr e major webs from the bash portions of the flexible carbon-carrier, the carbons and the forms to be typed extend around the platen to the rear thereof. As the typing proceeds, the work is line-fed in the usual manner, and the flexible carboncarrier, which lies between the work-webs and the platen, is line-fed with the work. The carbon-carrier, while sufficiently flexible to be fed around the platen, is nevertheless stifi' enough to feed the carbon-blades away from the platen at the line-spacing operation, and thus keep the carbons straight and unwrinkled.

When the typing on the bottom form section is completed, the platen is turned forward by one of the usual platen-turning ,kaobs to feed the work-webs and carboncarrier to a carbon-shifting position. In the carbon-shifting.position, cutouts in the carbon-carrier, situated just below the free lower ends of the carbons, register with openings in the front paper-table, and the carbons are straight and free of the platen.

Carbon-stripping auxiliary feed-rolls arranged to coact through said openings and cutouts are then moved from ineffective to effective position to grip the lower margins of the work-webs through the cutouts in the carbon-carrier and through the openings inthe paper-table. The platen feed-rolls are at the same time cast 0d. The auxiliary feed-rolls are thenrotated by a finger-piece while the carbon-carrier is held stationary to feed the work-webs one form length in anti-line-feed direction and relatively to the carbons. The lower ends of the work-webs pass from the front to the rear of the flexible carbon-carrier through a slit in the carrier located just below the cutouts, and as they are fed by the carbon-stripping rolls they pass along the rear of the carbon-carrier down to the platen and around beneath the platen from front to rear. It will be seen that the lower end of the carbon-carrier serves as a front-insertion guide for the work webs to direct the webs to and around beneath the platen.

When the shifting of the work-webs relatively to the carbons has been accomplished, the completed web-section is severed by a draw knife that is slidingly mounted on the back of the front paper-table and that projects through a slot in the papertable to the front thereof. The knife is located just below the openings in the front paper-table, and is a short distance below the slit in the carbon-carrier at this stage of the operation, so that it can sever the webs between. the carbon-carrier and the paper-table, The knife is sharp pointed so that it will he sure to separate atl/of the of the flexible carboncarrier and sever them.

When the typed wehsections have been severed, the auxiliary feed-rolls ma be cast off and the platen feed-rollsmay emade effective. After this has been done the number of webs to be used in typing the next form or communication may be determined by withdrawing the lower margins of any surplus webs from the slit in the flexible carbon-carrier, turning them with the interleaved carbons up and back, and clipping them in an inactive position by means of a clip on the carbon-carrier at the upper end thereof. When. it is desired to increase the number of webs in active use this may be done by withdrawing as many inactive webs from the clip as are required and inserting their lower margins through the slit'in the carbon-carrier.

Should it be desired to substitute a letterhead or other facing sheet for one of the work-webs to receive the original impressions, this may be done just after a completed set of forms has been cut off, by retaining in active use as many webs and carbons as the number of carbon copies desired, and by superposing the letter-head upon the outermost active carbon with its lower margin extending down through the slit in the carbon-carrier. The knife may be moved to a gaging position to serve as a lower edge gage for the letter-head in this operation, if desired.

When the rearrangement of the webs, if required, has .been effected, the carbonholder together with the webs is fed around the platen in an anti-line-feed direction to locate the fresh forms around the platen in first writing line position. In this operation, the carbon-carrier again acts as a front-insertlbn guide for the work-webs. The reverse feeding of the carbon-carrier and the work-pack to writing position may be effected by'rotation of the platen knobs, but preferably it is accomplished by seizing the end of the carbon-carrier projecting beyond the rear of the platen, together with the severed web-sections which are still in the machine, and pulling the carbon-can rier to the rear. The web-sections are thus withdrawn from the machine by this same operation in the grip of the operator, and may be disposed of in an orderly manner. The work is now in position for a repetition of the cycle with reference to the fresh websections.

An important advantage of the present invention is the elimination of creeping of loose plies or webs with relation to each other, which. creeping heretofore has been a Source of difliculty in typing upon separate continuous work-webs. The amount that the webs are fed around the platen in antiline-feed direction to locate them in first writing line position, is equal to the amount that they are subsequently fed i'forward The creeping in one direction may be counteracted by the creeping in the opposite direction for each form therefore, and hence no creeping needs to accumulate. It will be recognized, of course, that no creeping results from the feeding of the work-webs by the auxiliary rolls.

It is a further feature of the invention that there is no retardation of the workwebs in line-feeding due to the inertia of the webs or of the reels upon which the webs are sometimes carried. At the line? feeding operation, the platen has to feed forward only the carbon-carrier and the form-section which is being typed, and the inertia of these is very slight.

In accordance with one feature of the invention, provision is made for rendering the auxiliary feed-rolls effective by the same operation that renders the platen feed-rolls ineffective, and for rendering the auxiliary feed-rolls ineflective by the same operation that renders the platen feed-rolls effective. This not only saves the time of the operator but also assures that the work-webs will always be moved squarely with relation to the platen.

A further feature of the invention relates to the construction of the carbon-holding blades and to their mounting on the flexible carbon-carrier. The blades are superposed upon studs on the carbon-airrier and are clamped thereon, for example, by nuts, threaded onto' the studs. The carbons have loops on their upper ends which receive the blades. The blades have means to engage the ends of these loops to mechanically locate and retain the carbons in correct position longitudinally of the blades.

When it is desired to change the width of the webs in use, the operator feeds the flexible carbon-carrier forward com-'- pletely out of the machine and inserts.

No claim is made in this case to features disclosed in co-pe'nding application 676L839, filed November 15,1923, which shows and broadly claims web-severing mechanism of the type herein illustrated.

Other features and advantages'will hereinafter appear.

The Underwood Standard eorrespomlenee typewriting machine comprises a platen 1O revolubly mounted by means of a platena-xle 11. in the ends 13 of a platen-frame 12. The platen-frame includes, besides end members, a rear paper-shelf 14: and a paperapron 15 extending forward from the paper shelf, around the lower side of the platen 1() and conforming to the contour thereof. Feed-rolls 16 carried by bellcranks 17 pivoted on a shaft 18 are urged toward the platen 10 by springs 19. These feed-rolls 16 are arranged to be cast oft by depression of a finger-piece 2 which is connected through a rock-shaft 21. crank 22. link 23 and crank 24 to rock a cam-shaft 23 which engages the tails of the bell-cranks 17 to rock them to inil'ect-ive position. Brackets 26 are mounted by means of screws 27 on the ends 1;; of the platen-frame 1 12, and these brackets 26 are cgnnected to each other by a cross-bar 28 on which is mounted loo llld

lit]

i by the backing may catch thp be explained later.

a front paper-table 29, whereon the workwebs are presented to the machine, and from time to time straightened out for the carbonstripping operation. Continuous sheets or work-webs A are conducted, bottom end first, over the curved upper end -30 of the papertable 29 and down across its face to the platen 10 at the front thereof. The work-table 29 has fixed side walls 31 forming guides for a long sheet 32 of cardboard, celluloid or other flexible material, which serves as a carrier and backing for carbons 33 and at intervals is employed as a frontinsertion guide for the work-webs A, as will The carbon-carrier 32 has threaded studs 34 at opposite sides of its upper end on which carbon-holding blades 35 are mounted in superposed relation. Each blade 5 may be supported by both of the studs 34, when loose work-plies are used. Nuts 36 threaded on the studs 34 hold the carbon-blades Each carbonsheet 33 has i oop at its upner 'end in which av carbon-bl do, when detached from the carrier 32, may be inserted. The carbonblades 35 are cut away slight y between the ends, as shown in'l igure 3 to form shoulders 37 for engaging the ends of the carbonsheet loops to mechanically locate and detain the carbons 33 in the desired location longitudinally of the blades. The end portions 38 of the blades are made thicker than the middle portions 3.) thereof, ,the thicker end portions 38 serving to space the middle portions 39 from each other to afford clearance for the carbons and workwebs. The carbons 33 with the interleaved work-webs A extend downward from said blades together. The carbons 33 terminate just above cutouts 40 which are proridcd in the carl'ion-carrier or backing sheet for a purpose to be explained later, but the work-webs A extend across these cutouts 4t) and may be passed from the front to the rear of the backing or carboncarrier 32, through a slit 41 formed therein at the lower extremity of the cutouts, wherework-sheets and draw them around the platen. At the beginning of typing a form or communication, the parts are in substantially the positions indicated in Figure 10. The active portions of the work-webs A with the carbons 33 interleaved extend around the platen 10 outside the carbon-carrier 32 and terminate a short distance beyond the slit 41 in the carbon-carrier. As the typing proceeds the platen is line-spaced in the usual way, and this feeds the work-web A and the flexible carbon-carrier 32 forward together.

\Vhen the typing of the section has been completed the platen is rotated forward by means of either of the platen-turning knobs 42 (one of which is shown) to locate the work in a carbon-shifting position at the front of the platen where the carbons 33 and webs can extend in a straightened-out condition, and to locate the cutouts 40 of the carbon-carrier in register with openings 43 formed in the front paperftable 29. In this position the lower ends of the-carbons lie just above the cutouts 40 and openings 3, but the lower ends of the work-webs A extend down across the cutouts and openings and between auxiliary feed-

rolls

44 and 45, which may now be made effective to grip and feed the work-webs A down or in an anti-line-feed direction, while the earbon-carrier 32 with its carbons 33 is held stationary. The actuating rolls 44, whereby motion is imparted to the work-webs A, project through the openings 43 and are mounted on a shaft 46 journaled in the brackets 26. The shaft 46 has a knob, 47 fast on its end and this knob is provided with a small crank-handle 48. The arrangement is such that the shaft may be turned by operating either the knob 47 or the crank-handle 48, the crank-handle being preferable for turning the rolls 44 quickly through a great distance, and the knob being preferable for finely adjusting the position of the sheets.

A rock-shaft 49 journaled in the brackets 26 has crank arms .50 fast upon it which carry at their outer ends a shaft 51 that bears the pressure rolls for co-operating with the actuating feed-rolls 44. A spring 52 connected to one of the arms and to a bracket 53 fixed on the front paper-table 29 urges the rolls 45 toward the rolls 44. Means are provided for controlling the pressure rolls from the finger-piece 20, the arrangement being such that the pressure rolls 45 are automatically rendered effective when the finger-piece is moved to cast off the platen feed-rolls 16 and the pressure rolls 45 are automatically rendered ineffective when the finger-piece is moved to restore the platen feed-rolls 16. For this purpose, the rock-shaft 49 is provided with a crank arm 54 which is connected through a link 55 to a crank 56 fast on the rock-shaft 21. In the normal position of the finger-piece 20, as seen in Figure 2, the link 55 is drawn down by the crank 56 to hold the pressure rolls 45 released. It willbe observed that the link 55 is. on a dead center with relation to the rock-shaft 21 and crank 56 in this position of the parts, and hence the spring 52 will be powerless upon the feedrolls 45. As soon as the finger-piece 20 is depressed, however, the link 55 is raised and the feed-rolls 45 are moved to effective position under the urging of the spring 52. It will be noticed that provision is'made for lost motion between the link 55 and crank 54, the connection between these members being effected through a slot 57 in the link 55 and a pin 58 on the crank 54. Should it they have been inserted around the platen l to writing position, this lost-motion con- .1: nection enables the operator to take hold of the pressure rolls and swing them to in effective position, while the finger-piece 20 is depressed to hold the platen feed-rolls 16 ineffective.

set of forms has been completed and the work has been advanced to carbon-shifting position, as seen in Figure 7, the operator .He then holds the carbon-carrier \Vhen the typing of the end section or,

,depresses the finger-piece 20 to castofi' the platen feed-rolls 16 to make the auxiliary feed-

rolls

44, 15 effective (see Figure 8); 2 stationary with his left hand, while rotating the auxiliary feed'rolls l-f rapidly with his right hand by turning the crank-handle 48.

He thus strips the carbons from the workwebs and locates the work-webs A in websevering position, as seen in Figure 9. The web-severing position of the webs A with relation to the carbon-carrier '32 may be indicated by' suitable gage marks (not shown) on the carbon-carrier and on the work-webs, and the carbon-shifting position of the carbon-carrier may also be determined by reference to suitable gage tion,

marks (not shown) on thefront paper-table 29 and on the carbon-carrier.

Vhen the webs A are in severing posithe upper edge of the completed formsection coincides with a slot 59 in the papertable 29 through which a double-edged f draw-knife extends, and along which the knife may be drawn in either direction to sever the webs. The knife 60 is carried by a block 61 slidingly mounted in a channel bar 4 62 secured to the rear face of the papertable 29, and is moved from side to side of the table by a handle 63. The knife 60 normally occupies a position beyond the bounds of thework-webs A, but behind the carbon-carrier 32. The blade is sharp pointed to assure the separation of all of the webs A from the rear of the carbon-carrier,

' thereby to assure their severance by the knife. To further assure this result, the operator may press the carbon-carrier 32 toward the knife 60. The front paper-table has a tongue extending down between the o enings 43 through which the auxiliary eed-rolls 4.4, 45 act, and this tongue serves to prevent the lower ends of the work-webs A from catching on the bar 62 i when the webs are next fed in an anti-linefeed direction.

\Vhen the webs A have been severed, the

j finger-piece 20 is actuated to restore the platen feed-roll 16 to effective position and surplus webs A from the slit 41 in the carhon-carrier 32 and turning them, with thein carbons 33, up and back and clipping them in a clip 66 on the carbon-carrier. This clip comprises a stationary jaw 67 mounted on one of the threaded studs 34 and a swinging jaw 68 pivoted on an car 69 on the carbon-carrier and urged toward the stationary jaw 67 by a leaf-spring 70 which bears against a cam 71 on the movable jaw. Shouldit be necessary to increase the number of webs A in active use instead of diminish the number, the necessary webs may be withdrawn from the clip 66 and their lower ends may be readily inserted through the slit 41 in the carbon-carrier 32.

The lower end 72 of the carbon-carrier 32 extends around the platen and far enough to the rear thereof'to, enable the operator to seize the end 72 and draw the carboncarrier together with the carbons 32 and work-webs A from web severing to writing position. The typed and severed websections are removed from the platen by this operation. The work is now in the position shown in Figure 10, which is substantially the first, writing line position. The entire cycle of operations described may now be repeated with reference to the new web-section.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
