To all whom z'tmay concern:

Be it known that I,. Jo1m Q. SHERMAN, a citizenof the United States, and a' resident of the city of Da ton, in the county of Montgomery and S ltate of Ohio, have invente .certain new and useful Improvements in Manifolding Typewriters, of which the following is a full, clear, and exact descripto the drawings accoifi'panying this specification. y invention relates to manifoldin writers, particularly adapted for ma large number of copies on continuous of aper.

ne of the great difficulties in connection with the making of a plurality of copies of the same typewriter impression on the usual form of typewriting machine wherein the t pe operating devices are stationary and the platen movable, is that to provide continuous webs of paper has required the moving of a large bulk of paper along with the carriage of .the machine. It is one of the main objects of my invention herein, to provide for a stationary roll rack for the various webs of paper, and arrange for the maintenance of a suflicient loop of paper between the roll mounting rack and the typewriter carriage to permit of the carriage movement without resulting in straightening out the loop, the loop being sufficiently long to permit the typewriter carriage to move back and forth t e full length of its normal feed without tearing the paper webs. In connection with my machine I also provide for a rewind roll to retain one of y mg a webs the Webs of paper in the machine as a record .of type impressions, and

him this carbon paper mountin with the and means for maintaining lateral alinement of the paper webs.

The feeding mechanismfor the paper is of the type wherein rotating pin bearing bodies successively enter spaced holes in the paper, and while feeding the paper, act to og the webs thereof into line, thereby maintaming longitudinal alignment as well as feeding the paper past a point for reception of type impressions against a platen- I also provide for the mounting of carbon paper for use between the various films or webs, thereby providin for the transfef preferably commeans for maintaining lateral alignment of the paper films.

I also provide for various other improve.-

.my various objects ments ,and additions for manifolding ty writers which will be brought out in the ollowing matter and generally I accomplish by that certain construction and arrangement of parts to be herein.- after more specifically pointed out and clalmed.

which rides the usual typewriter carriage 2,

bearing the rotatable platen 3. It will be paper stora the exception of the a ditional feeding devices to be described, is the same as any ordinary typewriter and may vary w th the desi n of typewriter WhlCh' it is desired to em 0 I 'l hei e will be also any desired form of e frame 4, which is likew se stationary, an carries a rack 5, in WhlCh are set the desired number of rolls of paper 6, on spindle 6. v

The roll mounting should be such as to permit fairly free rotation of the rolls 6, and the webs of paper are preferably brought from each other and give to each web an independent path, so that it can travel free of friction, particularly when turning at any an is.

' he usual form of paper employed in connection with my machine will be webs printed up into corresponding forms upon which it is important that the impressions made on each form shall correspond as to position on the form, to all impressions on the remaining forms. The paper has on one or both margins a series of interspaced holes, punched with uniform relation to the printed, matter on the forms, so that when the holes are aligned the printed matter will be aligned also. For convenience the top most web of paper as it passes through the machine is indicated as A, and the bottom shegt as B. The spaced holes are indicated as As will be noted I employ the same set of marginal holes for both. lateral and longitudinal alignment of the paper webs, and

for the feeding of the webs to form the loop, hitherto noted.

Following the paper webs in their path from thestorage to the printing point and the record rewind, after they pass over the idler rolls, they are engaged by a feedingdevice. This device comprisespreferably a shaft 8, on which is mounted a'pair of pin 'bearing wheels 9, said wheels preferably having a groove 10, at the outer side thereof. A stripper plate 11 extends from the mountin pin 12 thereof, over the top of the sha t 8 and wheels 9, the outer ends of the plate being adapted to lie in the grooves 10 in the pin wheels and the plate being slotted to clear the pins.

The pins 13 on the wheels are arranged to engage in successive holes of the desired number of superimposed paper webs, andthe webs are kept down on the pins by means of a roller 14:, having pin clearance slots 15, and held on arms 16. A spring controlled shaft 17 serves as the mounting member for the arms, and the roller may be held out of operation by a latch 18. As will be observed the roller engages the rib 19 at the up from the. rolls and thence over' spaced idler rolls 7, which separate the webs outer ends of the pin wheels, therebykeepbut non-rotatably within this sprocket and rotates it in the same manner that the platen is rotated. The shaft is long enou h to ex tend through and o erate the sprocket in all possible positions 0 the typewriter carriage. Any other well known means of accomplishing this result may be adopted. The above paragraph refers to a preferred means of providing for rotationof the fixed sprocket.

Secured to the frame 4 is a sprocket 23, which is engaged and operated by means of a suitable chain 24, passing over the sprocket 22. A gear or pinion 25 on the same pintle with the sprocket 23 engages a like pinion 26 on the end of the shaft 8, thereby imparting rotation to the pin wheels and feeding the various webs of paper.

The mechanism, now described has been termed by me, as the loop feeding or loop maintaining means, since it maintains between the typewriter carriage and the storage frame, a loop of paper, as at D, which permits of a movable carriage and a fixed storage frame, without disturbing the uniformity of feed of the Webs of paper to the printing devices.

The frame 4 will preferably be extended forwardly until fairly adjacent to the typewriter frame, and may be walled up (Figure 4) so as to form an enclosed'paper storage and loop-containing cabinet. The typewriter carriage may also have extensions 27 thereon which act to retain the paper loop in shape, by a loose lateral confinement. The use of a feed of paper to the loop as well as from the loop permits of a compact enclosure and one which protects the loop completely.

After passing the loop form the paper is preferably next brought into line laterally by means of a series of idler pin bearing bodies, which likewise act as spacers to prevent binding of the paper webs at the turning point in their path to the platen.

A frame 28 is provided, which is secured to the typewriter carriage by means of,

clamping bolts 29, so that its angle may be adjusted, although this is not a requisite, ex-

vided which are mounted on pintles 31, that themselves are journaled in the frame 28, and carry spring 32, inside of the frame to press the washers inwardly. Carbon paper 6 rolls 33, having suitable cores are set over suitable pins or lugs on the inside of the washer p ates and are thus held in position. It is not necessary that a spring washer be rovided at each side of the frame, and I 10 ave thus shown the one side thereof as for equipped with pin bolts 34 having their ti s entering the carbon paperroll. he pint cs 31 are movable to perm1t removal of the carbon paper rolls, and are preferably knurled urposes of easy manipulation. ounted over the intles or pin bolts are idler sprockets 35 having hubs 35, and of the type generally known as pin wheel which have the pins thereon arranged to engage in 2Q successive holes in the webs of paper.

I have found that in forming up various multiple printed webs of paper with like printing and arrangement, that it is not practically possible to sever the wide printed webs into separate strips with exact umformity with relation to the margins of paper extending beyond the printed portion of the webs. The pa er slitters cut equal width stripsbut they sliift laterally so that the 0 printing is not uniform with relation to the ody of the strip.

It is for this reason mainly that I employ pin wheels enga in in marginal holes in the paper for latera a ignment, since holes can be punched with uniformity to the printing on the paper whereas the slitting into webs cannot be made accurate. v

' It will be noted that the carbon paper is set between the various webs and held 40 against movement by the spring washer arrangement, now described, and that the carbon paper is of less width than the lateral spacing of the marginal holes to enable it to pass between the pin wheels to the writ- ,-ing point. In order to bring fresh carbon 5 paper at the printing point I provide a special device to be described or else the .operator may hold the paper against the 2 platen at the -printing point and draw along so fthe carbon sheets together'with the films of regular paper.

Suitable gravity rolls 36, set in slots in the frame 28, rest in position to keep the webs of paper down on the idler pin wheels, without friction, being properly spaced from the us I individualize the films,

pin bearing bodies for free passage of paper, and stripper plates 37, mounted at the rear side of the idler pin wheels, and extending over the top of the wheels as well as across from side to side of the frame, serve to hold the paper away from the carbon rolls and lift it from the pins.

By provision of a separate lateral alignment. in wheel device for each web of paper, to the extent of preventing unequal action on them, and frictional contact between them. As in Y the case of all rolls to keep the webs of paper down on the ins, .I can substitute bars or fingers with li e effect, and do not insist in any respect upon fidelity to detail in the construction of machines according to my invention, as per my description herein, which is working machine of my preferred construcion.

After leaving the carbon paper and lateral alignment frame the paper passes, together with the carbon paper, down and around the platen, there being preferably, suitable guides 57, 58, engaging the paper to prevent its contact with the surface of the platen except at the printing point.

On the ends of the platen are formed suitable pin wheels 38, the pins of which engage in successive holes in the paper webs and draw them along step by step during the operation of the t pewriter.

The pin whee s are alike to those described for the loop feeding device, and a like spring roller device 40 is provided to keep the paper down on the pins, this roller being kept away from enforcing a frictional contact of the paper with the pin wheels or the guard or guides 57, 58 by means of the ribs 41 on the pin wheel bodies.

The record storage device is adapted to take one or more but preferably but one, of the webs of paper and wind it tightly and neatly on a roll supported above the platen. This device comprises a roll 42, mounted on a removable shaft 43, set across an upright formation of the typewriter carriage.

The roll will preferably be provided with a rod or clip 42 Figure 5, having a bent end 42 to seat in a terminal socket in the roll, thereby holding the paper steady on the roll in starting.

The roll is caused to revolve by a friction wheel 44, having a Vshaped convex periphery, and suitably clutched to or secured to the roll. also secured to it a ratchet wheel 45, which is engaged by a spring controlled lever 46, so as to be inhibited upon a forcing of the lever in a direction opposed to its spring pull. As a preferred form of lever, I provide the bent arm 46, which has a pawl 47, hinged to it by a butte hinge. This pawl is pulled by a string 48 permitting it to give, if it should strike the peak of a tooth of the ratchet 45, and is also pulled by a spring 49 which keeps the lever away from pawl contact.

On the end of the platen is a gear 50, meshing with a large idler gear .51, which is mounted on the same pin as a. carrying arm 52. This arm is spring impelled at 53, toward the rewind friction wheel, and carries a gear 54, meshing with the large gear in The friction wheel has 60 rious webs in alignment with each other, said all positions, this gear 54 carrying on its face a friction wheel 55, same having a V- shaped concave periphery to match with the convex periphery of the other friction wheel. This rewind device acts to feed the re wind .or record roll around in a frictional manner, and the inhibition of the move-' ment of the roll, is accomplished by means- 56 on the facecontacting with the lever 46 and-forcing it to lock the record roll against movement.

of a pin or stud or roller of the gear 50, said element the lower end of so that it will have a chance to be aligned by the platen pin wheels, when in a loose Or he may condition.

As so far described the operation of my machine is as follow. :-The operator first loads the racks in the storage frame with suitable rolls of paper, and brings the separate webs up and over the idler rolls set at the top of said storage frame. The carbon rolls are then put in place, and sufiicient paper pulled out to reach to the printing point on the typewriter platen. The Webs of paper are then passed between the carbon paper rolls, set over the idlers at the ends of said rolls, and brought down to-the platen where they are carefully aligned and set over the pins at the platen ends.

Before feeding the paper and writing thereon, the operator forms the loop D by drawing sufiicient paper off of the storage rolls, and then setting the various webs over the pins of the loop feeding pin wheels. free the webs from the platen pin wheels and revolvethe platen shaft manually, in the usual manner for typewriters, which will cause the loop feeding devices to accumulate the desired loop.

In any instance the alignment at the printing point is the necessary one, and the webs will not align at the unwinding orloop feeding pin wheels, as the under sheets of loop are engaged to hang further than the upper sheets giving that freedom of relative movement necessar for aligning action upon them. In settmg up the paper it is accordingly drawn with the films in proressively out of longitudinal alignment at t e loop feeding point.

' The usual operatlon of the machine as a typewriter will cause a feeding of the vawebs being free of frictional strains because of the loop and particularly the carriage and platen being free to move to and fro past the printing point, because of the and even roll, I

- terminates freedom allowed b the loop. Also,

the unwinding or oop feedmg pin wheels operate simultaneouslywith the platen pin, -wheels,"they may be readily made to feed the saper' -.ofi the storage-rolls at the same spee as It is fed past the rinting point, whereby the same amount of waIys remain in theloop.

paper will 9.1-

wishto note that whereasthe pin wheel devices above described are all in pairs, operatin on opposedmargins of paper webs,

that t e machlne W111 operate properly with but one sprocket instead of pairs in each instance and al'sothat other forms-of align ment devicesjcould be used together wlth the typewriter, such as, for example, that shown in myv application, Serial No. 161,940,

and April 14th, 1917.

- Also theexact nature of the means for passing the webs of paper around the printmg platen is not insisted upon, there being a number of ways hitherto devised by me and made subject of applications for patent covering devices for preventing the platen from actually feeding the strips and providing a loose or free engagement of the marginal holes of the paper with the pin wheels, such as shown in my pending application Serial No. 340,922.

As shown in Figures 10 and ll-of the present drawin s, this feature includes a pair of curved p ates 57, 58, mounted on rods 57*fiand 58 The plates are both slotted as at 59, for clearance of the feeding pins and guide the paper sheets to a substantially tangential printing point. The plate 57 below the printing point and the plate 58 extends above it to serve as a stripper and is cut away at the center to expose the platen to the papers as at 59.

In addition to the mechanism hitherto described, I may when desirable employ an automatic mechanism to provide for a regulated renewal of carbon paper, during the operation of the machine. Since carbon paper varies in quality, a machine also varies in touch, it is found necessary to renew carbon paper'at varying stages of its use so that any one distinct period of renewal would not be satisfactory.

In the mechanism to be described I provide a means at regulated intervals for pressing firmly together the films of paper and i the carbon paper, against the printing platen, which pressure or friction causes the carbon paper to travel with the films of paper upon operation of the line spacer of a typewriter.

The mechanism is shown in Figures 12-17 and the operator of plished.

a lever 67.

eral points so as to expose the laten, the preference being to have a num r of cuts 60 rather than a 'single wide one for retaining as much stren has possible in the guide plates and to keep the paper away from the platen.

A series of pressure rollers 61 are provided, mounted on a shaft 62 carried on a plurality of arms 63. The shaft 62 also is carried at one end by the end of the part 64 of a telescoping arm, having a part 65 and an intervenin spring 66 The arm :is mounted on a s aft 66, that is controlled by The lever 67 is adapted for hand 0 ration and is operated by a bellcrank' ever 68 mounted on the typewriter carriage and pivoted to the lever 67 at 69. By rocking the bell crank lever 68, manually, a clamping of the paper on the pins will be accomhis operation is ordinarily intended for use in holding down the paper while tearing of, as will be noted, and it is not interfered'with by the arm 65 to extension of the spring 66".

On the shaft 66 is also an arm 70 under 1 control of a spring 71, which is not as strong as the spring 66 in the telescoping arm de vice. This spring 71 tends to draw the shaft 66 into a position to bring the rollers Into contact with the platen.

For automatic operation the telescoping arm has on its end 65, a roller 72, which rides in a box cam 73, same having a cam flange with a notch therein into w ich the roller will move, under influence of the spring 71, thereby accomplishing a resilient extension movement of the rollers into frictional contact position. Some other arrangement' of the cam and spring could accomplish the same result, as the above, but it is preferred by me since it is a fully resilient movement, thereby providing an automatic take up for the thickness of paper on the platen, due to the number of webs of paper in use.

For operating the box cam it is mounted on a cross shaft 74 on the machine carriage which is rotated by a ratchet 75. This ratchet wheel is operated by a pawl 76, spring pressed at 77, and controlled in its mesh with the ratchet by a stop 78. The

stop operates as in a Underwood typewriter, and is mounted on a slide fork 79 held and guided on cap screws .80. The position of the fork is controlled by a bell crank lever 81, which works over a segment 82, and has apin at 83 to ride under a bifurcated. portion 79 of the .fork. This bell crank may be loosely mounted over the shaft that mounts the box cam, and ratchet, and the position thereof controls as to whether the pawl moves one, two or three teeth of the ratchet at a time.

feed of the carbon paper,

- For operating the pawl, a V-shaped lug 84 is mounted on .some fixed portion of the typewriter, which lug contacts with the end of a bell crank 85, mounted on the carriage of the machine. The inner end of the bell crank contacts with and thrusts over, when the carriage is moved transversely of the fixed body of the machine, a slide 86, having an antifriction roller 87, which slide is mounted in a guide plate or plates 88 on the carriage. The slide carries the spring pressed pawl, for meshing with the ratchet. and is itseif held by a spring 89 in a rea tracted position.

The operator interleaves the carbon paper, as noted above for manual operation, and

operates his machine in the normal manner.

Each passage of the carriage across the machine operates the pawl and turns the ratchet the desired number of notches. When the ratchet turns the box cam to a position for permitting the forward contactand opera tion of the friction rollers, thereby bringing the films of paper and carbon paper frictionally together, the next following operation of the ine spacer will carry along the carbon paper with the films of paper written upon, thus changing it at the printing line.

While the machanism described for manually exercising friction 'may be employed for use in advancin the car n paper, which would be somewhat clumsy due to the necessity of holding it down while the line spacer is operated, its chief use is to hold the aper while it is being torn off of the mac ine.

' I have shown as mounted on the support- 90, against which the films of paper may be I torn whenever desired. During this tearing ofi' the operator should press down on the bell crank lever 68 thereby holding the paper firmly against the platen and preventing its shifting during the tearing operation.

It should be noted of the guard or guide plate 58 which comes up over the platen and acts as a stripper for the various films, that it is so designed as to afford a base or resting place for the looseness or loop left in the record strip during the period of inhibition of the rewind device. While I have shown a device for clamping the paper during tearing off and during the which frictionally engages the aper on the platen, I also desire to provi e a special arrangement of the cross .bar or roller which is employed for keeping the paper down on the pins.

A showing of this has been omitted from the various assembly views for purposes of simplicity and because a complete operative machine may be had without it.

As shown in Figures 18, however, a special form of cam is provided for the pin wheel feed devices on the typewriter platen which cam permits the roller or bar to come down on the paper sufliciently to hold it tightly against the platen.

These cams which have been indicated at 80, have a series of notches 81 therein so placed as to coincide in position with the click of the line spacer of the type writer platen. Since the roll, here noted each time the typewriter platen comes to rest after a line spacing movement, the roller will be permitted to move into contact with the paper, thereby holding it while being written upon. As soon as the line s acing feed, and hence a rotation of the p aten, is set into motion, the roller will be lifted by the cams away from the paper, and will relieve it for adjustment during the pin feed. By a proper proportioning of the notches the release of the ressure may be made for the desired numher of line spacing movements.

By the use of this device I can do away with the hand operated clamping levers described as for use during tearing ofi, or merely use them for certain 'desired nonautomatic feeding of thecarbon paper. I cannot employ this new device'for carbon paper feed, however, since this carbon feed requires a release of pressure on the platen, while same is being revolved in a line spacing movement.

arious equivalent structures for accomplishing the objects of my invention, which will accomplish the various operations above described, will occur to the mechanic skilled in the art, and it is my desire that my invention be construed to cover such alternative structures, andthat my claims be construed with the full benefit of the doctrine of equivalents.
