TYPE-WRITER ATTACHMENT.

l Specmcation of Lettera Iatent. Application led August 1, 1908. Serialrlo. 146,363.y

To alfwhom 'it concern.; f

Be it known that I, THOMAS M. MORGAN, a citizen of the United States, residing at lVilliamsport, in the county of Lycoming and State of Pennsylvania, have lnvented' certain new and useful Improvements in Type'Writer Attachments, of which the following is a s cification.

My invention relates to type writing machines and particularly to manifolding at` tachments therefor.

The object of the invention is not only to simplify the structure as well as the means and mode of operation of such devices and attachments whereby they will be cheapened in construction, but willrender the machine more elicient and rapid in operation, easily adjusted, and unlikely to get out of repair.

A further object of the invention is to provide a device in which the record will be preserved in the form of astrip or scroll which may be iled. as 'a whole, representing the consecutive transactions or operations for a day or other given period, or may be subseguently separated for ilin purposes.

A urther object is to provi e an attachment in which the record strip other than the original will at all times be in place for instant use, permitting the operator to work more rapidly. The attachment is of especial value for telegraphers use when taking messages direct on the machine when but little time is possible for the placing of copy sheets and carbon paper. It is also useful in keeping records of bills and state-- ments, and other sho-rt written communica.J tions, and also 1n preparing lists as mailing vlists etc.

While the above are a few of the various uses to which the device may'be applied it is to be understood that it is not limited to such use. Further in the drawings-the atdental objects in view as will more fully appear from the specification the invention consists of the means, mechanism, construction, and mode of operation or their equivathe claims.u In the drawings Figure l is a side elevation of the' attahment as applied to an invisible writer, in which the platen roll'must be shifted to exhibit the work. Fig. 2 is a front elevation of the construction shown in Fig. v1. Fig. 3 is a side elevation of the attachment removed from the imachine, with the driving belts and `pulleys removed. F ig. 4 is a view somewhat diagrammatic showing the direction of4 travel of the-respective strips of paper. Fig. 5 is a detail view of one of the receiving rolls. Fig.A 5 is a transverse sectional View of one of the receiving rolls. Fig. 6 is a detail view of one of the guide rods. Figs. 7 and 8 are detail views of the knife support and the attachment thereof. Fig. 9 1s a side elevation of the assembled device mounted on a visible writer in which the platen roll has only revoluble movement. Fig. 10 is a Isimilar View removed from the machine with the drive belts and pulleys removed to exhibit the contour of the iframe.

lents hereinafter described and set forth in- Fig. 11 is a detail .f

perspective view of the knife support of the construction shown in Figs. 9 and Like parts are indicated by simllar characters of reference throughout the several views.

Referring to the drawings 1 is the carriage of the writing machine to .which the attachment is applied, in this case an invisible writer in which the platen roll 2 must be shifted forward to exhibit the work r riage l adjacent to each end thereof is a lug `(i to which is pivoted at 7 a frame member 8., v-The frame member 8 is held upright by` a frame bar 9 mounted on the trunnion 3 and engaging astud on the `frame member 9.

Pivotally attached to the frame bar 9 is a forwardly and upwardly inclined bar 10, retained in position by a hook bar 11 en- 'gagin'g a ,stud 12 in the frame bar 9. The rame construction erected at each end of the writing machine carriage are similar and the respective portions are united into one structure by tie ro ds 13.

Journaled in the frame member 8 are a copy paper supply roll 14a copy paper receiving Iroll 15, and a carbon paper supply roll 16, and in the upper end of the 1nclined'bar 10, a carbon paper receiving roll 17. While the respective rolls might be permanently journaled in the frame, but are l preferably removable to facilitate the removal and replacing of the paper supply. To this end the respective rolls are Journaled in notches or recesses 18. The shaft or trunnions 19 of the respective rolls are of slightly greater diameter than the width. of

"1 the notches 18, and are provided with jacent to the bearing points of the respec-I grooves 20 adapted to enga c in the recesses 18 of the frame and form earin s for the rolls. Pivotally attached to the rame ad.-

tive rolls are swinging clips or hook members 21, each having a notch 22 adapted to4 -may be separated into sections, and two guide .rods 24 and 25. The knife and guide rods-mafy be supported on anyr suitable part of the rame as for instance on the frame bar 9 as shown in Fig. 1, but is preferabl located as close as possible toi the platen ro l of the machine. V 4

The most desirable method of supporting the knife and iide rods is that shown in Figs. 7 and 8, in which 26 is a supporting member having .an outward projecting lug ,27 which is attached by a screw 28 to the upward projecting arm 29 on the platen roll support of the writing machine carriage, whlch arm also carries the trunnion '3. Thel supporting' member 26 is provided with notches 30`to receive the guide rods 24 and v25 which are provided with-grooves 32 to engage the notches 30 in a manner similar to theengagement of the roll trunnions with the notches 18 of thev frame. Intermediate the notches 30 in the members 26 are in clined grooves 33vv in whichl is removably located the knife 23, which extendsfacross the machine. The-paper rolls and more par- 4 ticularly the receiving rolls comprise a cyshaped tubes which may lindrical body 35, as shown in Fig. 5, in which is an intermittent longitudinal oove 36. The portions 37 of the cylindrica body separating the respective sections of the longitudinal oove 36 are perforated, and a removable pin 38 is located within the groove 36 and projects through the portions (37, for the purpose of securing the end of the paper strip to the roll as hereafter mentioned. v

The paper supply may be wound upon the supply roll by t e operator, but is referably suppliedin rolls upon cylindrica or other supply roll and the rol returned to the machine. Referring particularly to Fig. 4 the copy paper strip leads from the` supply roll 14 under the guide rod 24, about the platen be slipped upon the roll 2, under the knife 23, and thence to the receiving roll 15, to which it is attached by being pressed into the groove 36 and the pin 38 inserted throughthe paper and portions 37 thus pinning the paper to the roll.l

The carbon paper passes from the supply roll 16 about the platen roll 2 on top o the copypaper, thence under the ide rod 25 to the receiving roll 17. The first .sheet or original is inserted in the machine in the l usual manner as shown at 39. To facilitate the placing of the copy and carbon paper the rods 24 and 25 and knife 23 may be removed from the support 26, and the car# bon paper receiving roll lowered as lshown by dotted lines in Fig. 1 by disengaging -the hook 11 from the stud 12, to render the parts more accessible. As the writing machine platen roll 2 is rotated in the usual manner inthe course of operation, the copy aper and carbon paper are both drawn om the supply rolls 14 and 16, the pull of thev paper causing these rolls to revolve.

Each o 41 upon the4 projecting ends o shafts.

The pulleys of the supply rolls are larger than those 41 of the receiving rolls the pulleys of the corresponding rolls are connected the respective rolls carry ulleys 40, the roll by elastic belts 42 where the receiving roll vwill normally be driven at a greater s eed than the supply roll to insure that the s ack of the paper strips shall be taken u The comparative sizes of the supply an receiving rolls will constantly vary, the supply roll decreasing and the receiving roll increasing in diameter as'the pa er is transferred from one to the other. ikewise the speed or number of revolutions of the suppl roll will increase in delivering a 'ven ength of paper as the size of the rol decreases, and

the speed of the receiving roll will decrease as its periphery' becomes eater through the excess of paper receive from the su ply roll.' The variation in the size of the rive and drivenL pulleys is suicient to keep the paper stretchedat all times andany further variation in the speeds is compensated for e by the slipping -of the elastic belt 42 on the be supported on the pulleys. The platen roll 2 is advanced in the usual manner by the operator, which by the pull of'the paper drives the supply rolls; the supply rolls in turn drive the receiving rolls through the elastic belts 42. When the carbon pa er has .been transferred from the supply rol to the receivingV rolls the rolls ymay e reversed in lthe frame, the pulleys being interchanged, and the carbon paper returned to the original roll as the receiving roll. e i On- Sheet 3 is shown the attachment applied -to a visible writing machine. f In as much as the platen roll 43 has only revoluble movement the frame member 44 may laten trunnion, together with a suitable ug as 45 'adapted to rest on the machine carriage and support the frame member in an upright. position.

The various supply and Ireceiving rolls ,14,

- 15, 16 and 17 are similar to those before described 'and are mounted and driven in the, same manner. The roller 17 is mounted in an arm 46 and retained in -positionby a hook 47 inthe manner before described.

1 In Figs. 9 and l0 no uide rods such as 24 and 25 are shown but t le paper is conducted direct from the supply rolls to the platen and thence direct to the receiving rolls. It is obvious that in the iirst described construction the guides 24 and 25 may likewise be omitted and the paper conducted asin Figs. 9 and l0.

InI Fi 1l is shown a perspective view of the kni e support 48 provided with an in'- clined slot for the reception of the knife 49.

The support may be attached to either the frame member'44 or to the arm 46 as is shown in the drawings.

In the construction lirst described the i shifting of the platen roll ,2 will cause a f paper and copy pa er rolls ma volved or sacrificing any of its advantages.-

It is Afurther obvious the additional carbon be added, without dep'artin rom the spirit of the invention, thus ena ling^the operatorto make a plurality of copies as is ordinarily done.

plurality of rolls mounte Also the'supply and receiving rolls may be rovided for the original copy, orsirst sheet 1f it be desired to repare typewritten matter in the form ofp a continuous strip, such as lists of merchandise, or lists of names or 'when preparing mimeograph stencils of mailing liStS etc.

The modifications above suggested wouldV not involve any different construction from that shown in the drawings, but would be a mere multiplication of the parts and devices i therein shown, therefore it has been thought not desirable to addto the number of drawings views showing such duplication of parts.
