Nichols, Newark, N. .L, asslgnor to New Jersey Optical Company, Newark, N. 1., a corporation of New Jersey Application October 12, 1934, Serial No. 748,002 3 Claims. (01. 197433) This invention relates, generally, to writing machines, and the invention has reference more particularlyto improvements in typewriting machines employing flat writing platens.

Machines of this character as heretofore constructed are capable of writing or operating upon but a single set of continuous forms or sheets at a time and hence, whenever it is desired to typewz'ite common or partially common subject matter on two different sets of continuous forms, it has been necessary to typewrite the forms separately, i. e. one after the other.

The principal object of the present invention is to provide a novel improved Writing machine that is capable of handling or operating upon two sets of continuous forms simultaneously, thereby substantially cutting in half the time ordinarily required to typewrite two sets of forms where the typewritten matter written on both of the sets of forms is the same or partially the same.

Another object of the present invention lies in the provision of a novel writing machine of the above character having continuous tape means for feeding the additional or second set of continuous forms operated upon, together with means for protecting the top sheet of carbon paper used in connection with the first set of forms from the abrading action of the second set of forms passing thereover.

Still another object of the present invention is to provide a novel writing machine of the above character having snubbing means for regulating the feed of carbon paper from the additional carbon rolls used in connection with the second 3 time more particularly enumerated, will be clearly understood from the following detailed descriptionof the same.

The invention is clearly illustrated in the accompanying drawings, in which:

Similar characters of reference are employed in said views to indicate corresponding parts.

Referring now to the said drawings, the reference numeral l designates the frame of the Writing machine having horizontal side rails 2 and 3 at, its top which rails extend from the front to the rear of the machine for supporting a mov- .able rectangular carriage frame 4 that carries the typewriter 5 thereon. Rollers 6 provided on carriage frame 4 rest on the side rails 2 and 3 and enable the carriage frame 4 to be moved forwardly or rearwardly over rails 2 and 3 while rollers 1 provided on the typewriter 5 enable the latter to move transversely of carriage frame 4. By combined movements of carriage frame 5 over rails 2 and 3 and of typewriter 5 over carriage 39 frame a, this typewriter may be caused to write on any portion of the flat writing platen 8 carried by frame I.

One set of continuous forms l0, contained within a box 9 (see Figs. 3 and 9) extends upwardly to the rear edge of platen 8 and from thence forwardly along the. upper surface of this platen. Transversely extending carbon sheets i l (see also Fig. 8) supplied from a carbon roll l2 mounted at one side of the frame I feed through a slot 33 40 provided in side rail 2 and are interleaved with the sheets of form Ill and are rewound upon another roll l3 after use, the said roll I3 being positioned at the opposite side of frame I. The set of forms i0 is illustrated as consisting of three continuous form sheets (see Fig. 9) though a greater or lesser number of these form sheets may be used. Two of the carbon sheets i l are interleaved with the three form sheets comprising form set M. 5

A transverse clamp bar 20 is adapted to clampv the forward free end of form set l0 against the forward end of platen 8. A foot pedal I5 is pivoted at it and, when depressed-operates through link H and lever system I8-I9 to actuate the 55 transverse clamp bar 20 to released position, thereby releasing the form set ID. A tension spring 2i normally acts to hold the clamp bar 20 in applied condition.

The machine as thus far described is old and well known and would appear to require no'i'urther description. According to the present invcntion, a substantially rectangular carbon roll spaced relation from, side rail 3. The side bar 22 is provided with a plurality of mutuallyspaced bearing apertures 25 and the sidebar 23 is provided with upwardly opening bearing slots 26 for turnably receiving the end portions of carbon roll shafts 21 that carry carbon rolls 26. Three carbon rolls 28 are shown as thusly supported in the drawings, although a greater or lesser number of such rolls may be used. The right hand ends of carbon roll shafts 21, as seen in Fig. 1, project through the bearing slots 26 and have. ratchet wheels 29 fixed thereon.

Ratchet wheels 29 are normally engaged by spring pressed pawls 36 (see also Fig. '1) that are pivoted as upon screws 3| threaded into side bar 23. A push rod 32 is mounted for forward and rearward sliding movement in slide bearing apertures provided in brackets M, the said push rod having an operating handle 34. Push rod 32 carries pins 35 for engaging the pawls 30. By pushing rearwardly upon handle 34, the push rod 32 acting through pins 35 serves to overcome the tension of the pawl springs 36, thereby disengaging pawls 3|) from the teeth of ratchet wheels 29 and permitting the carbon roll shafts 21 to be turned as when drawing or pulling carbon paper off of the same. Any one of the carbon rolls 28 may be removed from the carbon roll frame by pushing handle 34 rearwardly and then lifting the right hand end of its shaft 21 (see Fig. '1) out of bearing slot 26, thereby causing the left hand end of'the shaft 21 to disengage its bearing aperture 25 in side bar 22. Thus, any desired number of the carbon rolls 28 may be removed from or inserted into the carbon roll frame at will.

In order to keep the carbon paper forming rolls 28 from unwinding or becoming loose on these mils, which would result in improper feeding of the carbon paper and also cause wrinkling, binding and tearing of the same in use, leaf springs 38 are provided, which springs have their lower end portions fixed to spring blocks 39 and are disposed so that their upper end portions bear upon thecarbon rolls as shown in Fig. 6. Spring blocks 39 are slidably adjustable along transverse bars 40 that have their ends fixedly carried by brackets 4| depending from side bars 22 and 23.'

By loosening screws 31 the transverse position of the spring blocks 39 may be varied to suit the positions of the carbon rolls on the carbon roll shafts 21.

A second set of continuous forms 42, illustrated as consisting of four continuous form sheets 43, 44, 45 and 46, is contained within a box 41 and extends'upwardly therefrom. The first or front form sheet 43 passes over a cross-bar 24 and from thence forwardly over the uppermost form sheet of the continuous form set H) (see Fig. 9). The second form sheet 44 passes over the first or forwardcarbon roll 28 and from thence over the form sheet 43, the carbon paper 48 from the forward carbon roll being interleaved between form sheets 43 and 44. The third form sheet 45 passes over the second carbon roll 28 and from thence over the second form sheet 44, the carbon paper i 48 from the second carbon roll being interleaved between form sheets 44 and 45. Likewise the fourth form sheet 46 passes over the third or rear .ly registering with one another.

carbon roll 28 and from thence over the third form sheet 45, the carbon paper 48 from the third carbon roll being interleaved between form sheets 45 and 46. i

All of the form sheets 43 to 46 comprising the second set of continuous forms 42 are provided adjacent one of their side edges with a series of equally spaced circular apertures 49, the successive apertures 49, of the several sheets respective- Apertures 4910 are arranged in longitudinal alignment with, and are adapted to be engaged by, a series of equally spaced pins or projections 50 carried by an endless metal tape or belt 5|, that passes around sheaves 52 and 53. .Sheave 521s fixed upon a transverse shaft 54 that extends across the front of the machine and is turnably supported in bearing's provided in brackets 55 attached to the machine'frame. A knob 56 is fixed on one end of shaft 54, and by turning this knob, sheave 52 is rotated, causing tape 5| to move so that pins 50, by engaging in apertures 49, cause the second set of continuous forms to move either fcrwardlyor rearwardly over the first set of forms l9, depending on the direction of turning of knob 56. The sheave 53 is shown carried by a shaft-51 that extends through a slot 58 in side=rail 2. By loosening a nut 64 on shaft 51, the tension of tape 5| may be adjusted.

The upper run of the endless tape or belt 5| issupported intermediate the sheaves 52 and 53 by a ledge 59 (see Figs. 4, 5 and 8). projecting from a bar 60. that extends along the inner surface of side rail 2 and is secured to this rail as by screws 6|. Another bar 62 overlies the upper run of the endless tape 5| and extends along the inner surface of side rail 2, this latter bar being secured to this rail 2 as by screws 63. Ledge 59 prevents any sagging of the upper run of tape or belt 5| and hence retains this run of the belt in proper alignment with the sheets of the second form set 42. Bar 62, by overlying the side edge portion of the upper form sheet 46, prevents the sheets of that part of the second form set overlying platen 8 at any time from disengaging drivingpins 50, so that positive movement of the sheets of the second form set is assured whenever knob 56 is turned.

The carbon roll I2 is provided with a carbon sheet 65 that is illustrated as narrower than the other carbon sheets H of this roll (see Fig. 9) to suit the requirements of acertain type of work as will further appear, although for other types of work the carbon sheet 65 may be 01' the same width as the sheets As the form sheets 43 to 46' constituting the second form set 42 are moved forwardly by means of knob 56 over the first form set I0 lying on the platen 8, the forward or leading edge of the second form set would tear or injure .the transversely extending carbon sheet if means were not provided for protecting the rearward side edge of this carbon sheet. This protecting means comprises a transverse horizontal plate member 65 66 overlying the first form set In on platen 8, which plate member is rigidly connected at one end portion to the forward end of a rearwardly extending bar 51. Bar 61 extends through a slide bearing bracket 68 fixed on the side rail 7 3 and has its rear end'portion attached as by screws 69 to a collar 10 that is slidable along a round rod 1|. Rod 1| has its end portions fixedly carried by brackets 12 secured to side bar 23 and this rod is provided with stop collars 13 ad- Figs. 6 and 9).

justably fixed on this rod for limiting the sliding movement of collar 10.

A coil tension spring 14 has one end connected to one of the screws 89 and its other end connected to a rear cross bar 24 and normally serves to hold the collar 10 against the rear. stop collar 13. A flexible cable 15 has one end connected to the collar 10, passes over a pulley 16 on forward cross-bar 24, and has its other end connected to a pedal lever IT that is pivoted at 18 upon a fixed bar 19 carried by a cross-frame member 80. By depressing pedal lever 11, cable 15 serves to move slide collar 10 forwardly along rod 1| against the tension of spring 14, thereby moving bar 61 forwardly so that plate member 66 moves from its rear dot and .dash position shown in Fig. 9 to its full line position shown in this figure, in which latter position the said plate member 66 overlies the rear edge portion of carbon sheet 65 in protecting relation. The forward edge portion of plate member 66 is upturned somewhat at at to facilitate the movement of this plate member over the rear edge of carbon sheet 65. With the plate member 56 in its forward position, the second form set 52 may be advanced over the first form set on platen 8 without injuring carbon sheet 65, since the plate member 66 overlies the rear edge of the carbon sheet 65 in protecting relation.

In order to maintain the several sheets of the second form set 62 together with the interleaved carbon sheets 48 in a smooth, fiat, and unwrinkled condition, regardless of more or less forward and rearward movement of these sheets over the platen 8 in use, a finger strip 83 is provided which is secured at its rear end to a block 84 that is turnabiy mounted on a crcss-bar 23 (see Finger strip 83 preferably has a somewhat resilient forward end portion 85 for yieldably engaging the upper surface of the second formsheet it, to thereby retain the second form set and also the first form set in fiat condition over the platen B. The weight of finger strip 83 together with that of block 84 causes this finger strip to bear with a definite light pressure against the second form set 42, which pressure may be varied at will by means of a screw 86 threaded through the lower portion of block 84 and engaging a cross-bar 24.

In use, assuming that it is desired to typewrite two sets of forms simultaneously, 1. e. form sets H] and t2, and that it is desired to typewrite a heading such as a name and address and perhaps other matter on the sheets of form set it) which heading and other matter is not desired to be written on the sheets of form set 42, although the body of the typewritten material such as an order, bill, requisition, and, etc. is to be typewritten on both form sets. The first form set ii] is then pulled forwardly over platen 8, the sheets of the same being interleaved with the carbon sheets ii as shown in Fig. 9, the narrower carbon sheet 65 overlying the top sheet of form set it. The heading and any other material that is to be typed only on the sheet of form set it, is now typed by use of typewriter '5 on the upper or heading portion of the top sheet of form set til, i. e. on that portion of the top sheet that is to the rear of carbon sheet 55 and overlying carbon 'sheet Ii. After this material has been typed, the form set 42 together with the interleaved carbon sheets or paper Ml are then advanced over the first form set ill by turning knob 56, care being taken to depress pedal lever Tl so as to move plate memvery valuable in many lines of business where bar 66 into overlying and protecting relation to carbon sheet 55 and to-also push "handle--34 rear-l wardly so as to allow the carbon sheets 48 to feed along with the sheets 43 to 46 of form set 42.

After the sheets of form set 42 have been moved forwardly so as to overlie the-form sheets l0 and the carbon sheets H and 65, the typewritten matter to appear on both form sets is typewritten upon the. top sheet 46 of form set v 42 in the area underlain by carbon sheet 65, this carbon sheet and carbon sheets ll serving to transfer the typewriting to the sheets of the first form set l0. During the typewriting operations, the sheets of the first form set In are held at their forward edges by clamp bar 20, whereas the pins 50 of tape 5| acting in conjunction with bars 60 and 62 serve to hold the sheets of the second form set 42 and the carbon sheets 48 in fixed position.

After thus typewriting one sheet and producing the desired number of carbon copies of both form sets l0 and 42, the knob 55 is turned so as to further advance the second form set 42 so that the typewritten sheets move forwardly of 25 platen 8 and may be torn off along the forward edge of this platen. .During'this turning movement of the knob 58 the handle 34 of push rod 32 is not touched so the carbon rolls 28 are held against turning by the action of pawls '30 engag- 30 ing ratchet wheels 29 and hence the carbon sheets 48 do not feed beyond platen 8.

of the form set 42 and the carbon sheets 68 are not allowed to bulge up or wrinkle during this movement but are causedto lie fiat and produce slack in the vertical runs of the sheets at to 45 at the rear of the machine. The leaf springs 38 engaging the carbon rolls 2% prevent uncoiling45 of carbon paper from rolls 28 at this time. Clamp 2b is now released and the typewritten sheets of form set iii pulled forwardly and torn on at the front edge of platen 8 preparatory to typewriting another set of sheets.

Thus, it will be seen that when using the improved machine of this invention, two sets of forms may be handled simultaneously, and these form sets may be similar as to size or dissimilar as shown in the drawings. Either the entire typewritten matter appearing on one form set may also appear on the other form set, in which case the carbon sheet would be of the same width as the carbon sheets H, or only a portion of the typewritten matter appearing on one form set need appear on the other form set, if desired, as described in connection with the operation of the machine.

The novel improved machine of this invention is two sets of forms having the same or partially the same subject matter is desired.
