14 Claims.

This invention relates to a speed feed manifolding attachment for typing machines having a platen mounted upon a carriage for translation past a fixed typing location.

It is a purpose of the invention to provide an attachment that may be adapted for-use with tively feeding superposed; webs or sheets of-paper,

interleaved with sheets of carbon paper into typing relation with the platen and to automatically retract the carbon paper sheets as a unit to a position to begin a new typing operation, while maintained in interleaved positions between said webs.

A further object is to provide means positively holding the superposed webs in proper relation and moving with them during line spacing movements, but manually releasable from the webs and movable independently to a position engaging the webs for the next succeeding typing operation.

A still further object is to provide a frame construction in an attachment of the character described and using a plurality of endless chains or other band elements, wherein the effective lengths of the chains may be quickly and easily varied and the chains given the proper tension.

Another object is to provide a novel connection between the chains or other elements, as in the preceding paragraph, and the carbon paper attaching mechanism, whereby all parts connected to the chains may be quickly adjusted into proper relation.

Another object is to provide a universal speed feed manifolding attachment that is relatively simple and inexpensive to construct, easily operated, efiicient, rapid and positive in operation and that may be held in position simply by resting the weight of the typing machine thereon.

Another object is to provide a universal speed feed manifolding attachment that can be rendered inoperative without removing the typing machine therefrom or removing the manifolding machine from the typing machine.

Other objects and advantages of our invention will become apparent as the description proceeds.

Referring now in detail to the drawing wherein like reference characters identify corresponding parts throughout, M, Figure 2, indicates the frame of a machine of standard construction with which our invention is adapted for use and which may be a typewriter, billing machine, or other machine 0, having a platen P rotatable on its axis to effect line spacing and sweep feeding of the paper, and movable axially to effect letter and word spacing. At F we have indicated a fan-folded stack of paper forms folded along hinge sections and threaded through the attachment and around platen P. While the paper supply has been shown as a folded stack, it will be understood that the invention is not limited to a supply in this particular form, but, if desired, may be in the form of a roll.

A base is formed of sheet metal and has lts rear and side edges Illa and [0b upturned and overlapping at the corners, as indicated at Inc, Figure 3. A bolt Hid passes through aligned holes in the overlapping edges to unite them into a reinforcing rim. This base is adapted -to be secured in any desired manner to the typing machine with which it is used. The connection may be effected simply by resting the rear portion of the machine on base 18, Or it may be made positive as by means of bolts or latches, not shown. A pair of sockets II are attached to base [0. A hollow column i2 is secured at its lower end within each socket II, as by means of a set screw I3. The upper ends of the columns l2 are axially split as at lZa, Figures 2 and 3, to form resilient portions each encircled by a clamp 14 having apertured lugs 14a. Each column 12 is braced at its upper end by a sloping bracket [6 which may consist of a metal strap secured at one end to base ID by means such as a screw ll. At its upper end, each bracket is secured to the lugs of its clamp I4 by a screw 15 which passes through aligned apertures in the bracket and lugs. A post [8 slidably fits within each column i2 and is secured in vertically adjusted position therein by constriction of the upper split sections of column 12 when screws l are turned home to draw lugs [40. together. Screws I5 therefore, perform the dual function of clamping posts l8 in adjusted height and securing brackets IE to the upper ends of columns I2, to hold the parts rigidly in position.

The posts l8 are rigidlyconnected together in parallel relation, by tracks 19. These members l8 and 19 are secured together as by rivets 28 to conjointly form a track frame 2| wherein tracks 19 are parallel and substantially coextensive with the width of the machine. By loosening screws I5 the frame 2| may be adjusted in height for the particular machine with which the invention is to be used, after which the said screws are tightened to rigidly hold said frame in the desired position of vertical adjustment.

.A carriage, indicated generally by numeral 22, Figures 1 and 2, is formed by bars 23 secured in spaced parallel relation by short strips of angle bar 24. A series of rollers 25 are journaled on anti-friction bearings at spaced points along bars 23. These rollers have their peripheries grooved and are so spaced in a vertical direction as to engage the facing edges of tracks l9 whereby carriage 22 is freely movable along said tracks by and with the axial, type and letter spacing movement of platen P, through connections subsequently described.

Reverse angle brackets 26 are fixed at one end by rivets or bolts 28, to the angle bars 29, as shown in Figure 2, and have their offset ends pivotally connected, as at 21, to the bars 24. The brackets 26 have the depending end portions 26a which abut the pins 24a when the unit is in its Figure 2 position. As shown in Figure 4, bars 29 are interconnected at. their upper ends by a spacer rod 3! that also has a reduced threaded hole.

portion 3la passing through alined holes 32 in the adjacent bar 29 and a clamp bracket 30. A nut threaded on said reduced end, acts to secure each bracket 30 in position on its bar 29. It will be understood that the construction shown at Figure 4 is duplicated at the other end of rod 3! whereby the two bars 29 are held in spaced relation at their upper ends.

Each bracket 30 is bent as at 38a, to encircle the upper end of a tube 33. The portion of each tube encircled by clamp 30 is longitudinally split, as at 33a, Figure 4, whereby, when the nut on bolt 34 is tightened, the tube is constricted into binding contact with a rod 35 otherwise axially slidable within and along its tube. An offset bracket 33 is fixed to each rod 35 to extend a short distance rearwardly therefrom. At their free ends, these brackets rotatably support a shaft 31 having fixed thereon a roller 44 over which the paper supply passes, as will be described later.

A guide plate 38 has its ends secured tangentially to the respective circular portions of brackets 30, as by means of screws 39, to thus extend transversely across the upper front portion of the attachment. Plate 38 is slotted as indicated at 38a. and 38b, Figure 1, and a pin 48 is fixed in adjusted position ineach slot, as by means of washers 41, and 42, and screw 43, as will be obvious from inspection of Figure 4. Pins 48 are intended to be so adjusted as to contact the edges of the paper and guide it downwardly after passing over roller 44. By this construction, on loosening of bolts 34, rods 35 may be telescoped within, or withdrawn from tubes 33, to vary the elevation of roller 44, for a purpose subsequently described.

From Figures 2 and 5, it will be noted that each tube 33 is slotted longitudinally along substantially one-half of its lower length. This slot has an angular extent in cross section less than so that sections of rod 45 positioned within the tubes, are limited to sliding movement therealong. Each section '45 has a flattened side, as indicated in Fig. 5, into which opens a tapped The flattened side lies substantially below the edges of the tube slot so that an element as 46, may be adjustably fixed along the slotted portion of the tube by tightening a screw 47 passing through the element and engaging r the tapped hole in section 45 to thereby bind the section 45 within the tube.

In Figure 5, the foregoing construction is used to mount a pair of arms 45 for adjustment on and along the respective tubes 33. The arms are apertured at their rearward ends and jointly journal a shaft 48 having idler sprockets 49 affixed thereto, so that, by loosening screws 4's", arms 43 may be adjusted along tubes. 33 to vary the tension in chains 50 and GI passing thereover and subsequently described in detail. Other sections 45 are used to adjustably mount a guide I85, Figure 2, and a pair of brackets 5! described in detail later. Each arm 46 at its free end, extends into sliding contact with. one leg of angle 29, and, midway of its ends, rotatably supports one end of a shaft 48 having fixed thereon a pair of spaced sprockets 43 and 50. It will be noted that rods 3.5 and .45 are separate and distinct elements. Also, as will be noted from Figure 2, each bar 23 and its associated tube 33 make a small acute angle with each other.

A bracket 5.! connects the lower end of each bar 23 with the corresponding end of its associated tube 33. One end of this bracket is secured to tube 33 and rod 45 in the manner explained tioned as to greases g in connection with arm 46, while the other; or free end, rotatably supports one end of a shaft 52, both ends being similarly mounted. A pair of sprockets 53 are fixed to shaft 52.

Each tube 33 has a bracket 54 secured to its lower end, and these brackets rotatably support between them, a shaft 55 having fixed thereon, spaced sprockets 55 and 51. All shafts 31, 58, 52 and 55 are parallel. Shaft 37 has sprockets 58 and 59 fixed thereon adjacent the ends of roller 46, and from Figure 1, it will be noted that the previously-identified sprockets at corresponding ends of shafts 37, 48, 52 and 55, are coplanar and are connected by endless chains 60 and GI passing over the respective sprockets and meshing with the teeth thereon. By this construction, all of the aforesaid shafts are connected for simultaneous rotation, and all passes of the parallel chains move in synchronism.

As will be noted upon Figures 1 and 7, the left hand bracket 36, as viewed in Figure 1, has a housing 62 fixed thereto, within which is positioned a coil spring 63 fixed at its inner end to shaft 37, and at its outer end to housing 62. By this connection, as chains 65 and BI move synchronously with the paper during line spacing operations, sprockets 58 and 59 act to rotate roller 44 and shaft 3? and to place spring 53 under continuously increasing tension. This tension is sufiicient so that, when one form has been printed and the paper has been released '(as will be subsequently described), spring 93' acts to reversely move the chains into position necessary to initiate the movement into typing position of the next succeeding form.

As clearly shown in Figures 1 and 2, a shaft 64 passes through, and projects a substantial distance beyond, brackets The shaft 64 is secured against axial movement with respect to brackets 5| and at each end carries sleeves 65 and 66 ad- 'justably secured in position axially therealong by means of set screws 59. Each sleeve has fixed jthereto an arm 61 and 68, respectively, forked as at 67a, Figure 2, to receive a part of the typing machine with which our invention is to be used, such as the shaft of platen P. It is intended, of course, that these arms 67 when in the position shown in Figure 2, shall connect the platen P .and carriage 22, to move axially as a unit.

While to avoid an excessive number of lines, we have shown the paper supply F, Figure 2, as a single sheet, it will be understood that our speed feed attachment has its greatest utility when used in connection with a plurality of superposed strips or forms such as are employed in making out bills, where one original and oneor more copies of each bill are desired. Thus, supply F will usually consist in a plurality of superposed strips with aligned hinge joints H and aligned r perforations adjacent each hinge line; and in ;order to make the desired copies of each bill,

carbon paper must be interleaved with the super- .posed forms as they pass around platen P.

For the purpose of providing the required numform or bill has been completed, I provide a backing plate in extending transversely across chains 60 and BI, and having its ends in sliding, guided 70 contact with tubes 33. Plate 10 has loops 7| secured thereto, through which the respective chains 69 and El pass. Offset spring arms I2 are secured to each end plate, so shaped and posilightly contact the respective tubes 'n from angle bars 33 and hold the plate in sliding contact with'saidj tubes.

A spring arm 13 has both ends shaped as shown at Figures 9'and 10, and is riveted, or otherwise secured at its central portion, to the rear side of plate 79. A pin 74 is secured to each end of arm 13 adapted, when in the normal position shown at Figure 9', to pass through a hole in the corresponding loop "ll and the adjacent link of the chain 69; Means for releasing pins 14 from the chain are shown at 15, in the form of oifset lugs attached to, or integral with the ends of arm 73, and projecting'forwardly over the top edge of plate 10. When it is desired to adjust the position of plate 75, relatively to chains 69 and 5|,

the operator simply presses 0n lugs '15 to retract pins 14 to the position shown at Figure 10, where upon the plate?!) may be manually adjusted upwardly or downwardly as desired.

Guide pins 16 are secured to project from each end of plate 19 and are so spaced as to receive the apertured ends of strips 11 which strips are attached, in any desired manner, to the upper edges of respective sheets of carbon paper C. In this manner, plate 70 and carbon sheets C, may, at the p'ropertime, be moved upwardly as a unit by the action of spring 53, shaft 37, and chains 65 and BI. Pins 75 are grooved at their outer or free ends, to receive the forked ends of a guard strip 78, extending therebetween.

It is desirable to maintain the corresponding forms or the superposed paper webs in longitudinally aligned position asthey pass through the machine, not only so that each line of typing shall have the same relation or spacing with respect to the top andbottom edges of the corresponding forms, but also so that the superposed forms may be easily separated from the web along their hinge lines in a single operation To this end, we pro vide the mechanism shown in detail at Figures 6, 8, 1:1 and 12.

A strip 19 extends across the rear parallel faces of angle bars 29 and is held in sliding contact with said faces by spring fingers and BI, se-

cured to strip 19 as by rivets 82, and engaging the opposite faces of bars 29. strip 19 has up.- standing apertu-red lugs 83 and 84 at its ends and pivot bolts 85 and 36 pivotally connect the respective lugs with corresponding lugs 8'! and 88 secured to an operating bar 89 which, as shown at Figure 1, is sufiiciently long so that its ends project outwardly beyond bars 29, whereby bar -89 may be conveniently grasped by the operator. As shown at Figures 11 and 12, bar 89 may be a right-angled strip. By this mounting, bar 89 may be given a pivotal movement toward and 29. A rod 95 is secured to strip 79 in a position offset to the rear thereof, by angular brackets 9 I, each having one arm secured to strip 79 and its other arm apertured to receive the end of rod 99. Collars 92 are mounted upon rod and fixed thereto as by set screws 93 in position abutting the respective facing surfaces of brackets 9| whereby the rod is secured against axial movement. The rod is notched or channeled at its central position as at 94, Figure 6,

and a tension spring 95 has one hooked end ento, eachso positioned asto lie in the path of a series of preformed superposed apertures in the paper webs F. The "free ends. of. the standards are slotted to receive a small roller 91, j-ournaled within the slot, on a pin 93. SeeFigure 11., Thus, when the paper webs. F are properly aligned and positioned in the machine, standards 96 will :pass therethrough when rotated with-bar '89 into the position shown at Figure 11, and the superposed forms are thereby held in. correct relative; position. As the paper is fed; by actuation of platen P, the bar 3.9 together with all parts attached thereto, move upwardly as a unit in. accordance with the paper-feeding movement.

At one end, spaced from the side edges or the paper, an arm 99 having a hooked end 99a, is secured. to, and extends downwardly from, bracket 87. A stud I!) is secured to the adjacent angle bar 29 near the lower end thereof and the parts are so related that when the paper-aligning means is at the lower end of its travel, hooked end 99a engages beneath stud I90 when bar 89 is thrust rearwardly to move the parts to the position shown at Figure 12. This construction affords a means whereby the aligning means may be correctly located in position prior to the start of a form-typing operation. If desired, a U-shaped strip It]! may be attached to pivot with bracket 81 and bar 89 and so positioned that one leg acts as a stop against bar 29 limiting the inward position under urge of spring 95, while the other leg acts to limit outward movement as by engagement against bar 29. In order to assure that the paper does not move outwardly when bar 89 is thrust outwardly, that is, to assure that standards 96 and their rollers are always withdrawn from the apertures in the paper, a rod N12 is mounted parallel to, and spaced slightly from, strip 19. This mounting may be effected by means of brackets IE3 secured to strip 19. Stri or plate 19 is in contact with chains 60 and BI and is secured thereto by bolts l 04, Figure 8, whereby the paper-aligning means is moved as a unit with said chains. Ahar I05 extends between and rigidly joins the upper ends of rods 35.

In Figures 13 to 16, inclusive, We have shown the various significant. steps involved in the use of our speed feed attachment; and for simplicity we have shown but two paper webs, with a single sheet of carbon paper C therebetween. It will be understood, however, that any number of webs and interleaved carbon sheets may be used within the physical limitations of this type of manifolding, and the typing machine itself. Figure 13 shows the webs and interleaved paper in typing position over platen P. Pins 14 are in engagement with their respective chains 60 and Bi and standards 96 are engaged within the superposed holes in the paper strips. Therefore, as platen P is operated in line-spacing operations, the paper, chains and standards, move as a unit. As soon as the typing of a form has been completed, the platen is reversely rotated until the carbon sheet is freed therefrom, as indicated at Figure 14, Because of the tension in spring 63, the parts of our attachment are automaticall reversely operated during this movement. The operator next presses outwardly upon bar 89 to thereby move the parts to the position shown in Figure 12 wherein the paper is free from the chains 60 and BI. It will be noted that the hook 99a at this time engages with the stud I90. Thereafter, the paper is fed forward a predetermined amount by rotation of the platen thus bringing the file holes in the paper out of register with the standards 96. .At this time the operator of the machine may rechine on base l9.

lease the pressure on thebar 89. and the standards 9,6 will merely ride on the surface of the paper. The entire assembl including the standards is retained in position by the engagement of the. hook 99a with the stud I00.

It will be apparent that this also holds. the chains stationary and therethrough supports the carbon sheets in a stationary position. Accordingly, the operator merely rotates the laten until the form is fed out to the first typing line on. the form immediately following the one which has just been typed.

During this last mentioned movement of the forms, the file holes of the succeeding form will move into alignment with the standards 96 whereupon the spring 95 will move the said standards into the file holes, release the hook 99a of the stud mo and once again interconnect the chains and paper for simultaneous movement. The carbon is thus automatically aligned with the next form by a very simple operation.

When the bar 89 and its attached parts have been moved downwardly into position such that hook 99a is engaged under stud Hill, the carbon sheet C has been moved to proper position for the start of a new operation, as shown at Figure 15. The platen is then operated to advance the just-typed form into predetermined position which may be indicated by any suitable gauge or mark on the machine itself. This position is such that a set of apertures in the superposed webs are positioned to be engaged by standards 96. The operator then releases bar 89. so that spring 95 may act to move the standr ards through said apertures and thus positively connect the aligning means and chains to the webs. The webs and carbon sheet are then advanced to a position as shown at Figure 16 ready to start the typing of a new form. The justtyped form is torn off as indicated at T, Figure 16, and typing is resumed. The entire operation just described is completed in a smooth, continuous and rapid motion requiring only a few seconds at most. Not only does it save large amounts of time over the operations wherein the carbon sheets are interleaved by hand, it also effects a large saving in carbon paper since each sheet may be repeatedly used. Furthermore, by pressing on release elements 15, to withdraw pins H from the chains 60 and 6|, the operator may shift the carbon sheets slightly up or down to engage said pins with the next succeeding links of the chains whereby to bring fresh unused portions of the carbon sheets into position such that they will be used in the succeeding typing operations. In this way substantially the entire surface of each carbon sheet is used. New carbon sheets are easily inserted simply by snapping the forked ends of strip 18 out of the grooves in pins IE, removing strips Ti and the attached sheets from said pins, applying fresh sheets in an obvious manner, and snapping strip 18 back into position.

As shown, our attachment is easily adapted to a machine simply by resting a part of the ma- Screws [5 are loosened and posts l8 adjusted to a height such that the forked ends of arms 6'! may slip over the hubs of the platen knobs. The set screws fixin arms 6! to shaft 64 are loosened and each arm is adjusted to fit snugly against the inside surface of the adjacent platen knob. These operations require but a few seconds at most so that our attachment may be connected and disconnected rapidly from a standard machine whereby a single ma- "chine maybe transferred, almost instaneously, :from standard typing work,-to billing operations, and vice versa, to thereby save large sums of money where separate expensive billing machines had to be purchased. The attachment is relatively simple, and easy to' attach It requires inc special skill to operate, and an operator can 'learn to use it quickly and easily. I

' In Figure 1'7 the typing machine and manifolding attachment are illustrated with the manifold- ;ing attachment pivoted about the pivots 2'! until "it is disengaged from the platen P. The manifolding attachment may rest on the table which :supports the machine or may abut the upper track. i3. In either case the typewriting machine .M is free to be used as a standard machine without any interference from the speed feed attachment. The attachment may be again placed in :operative association with the platen P bypivot- .ing it about the pivots 2'! and engaging the arms i6! with the shaft of the platen P at either end thereof.

' While, in order to comply with the patent statutes, we have shown and described a specific Zembodiment of our invention, numerous alterations, modifications, and substitutions of equivai-lent parts, will be obvious to those skilled in this art. Hence, we wish it to be understood that 'our invention is not to be circumscribed by the precise construction shown but embraces and includes all such alterations, modifications, and substitutions as fall within the scope of the subjoined claims.
