Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed January 21,1907. Serial No. 353.279,

To all whom it may concern:

Be it known that l, lessen ()irrrrnitncn, of Missoula, in the county of Missoula, St ate of Montana, have invented certain new and useful improvements in 'lypev'riter Attachments, of which the following is a specification.

The object of my invention is to produce a device adapted to be attached to a typewriter designed and adapted'for manil'olding without handling the carbon paper or the paper upon which the copy is printed. The end referred to is aemnnplishedby the em ployment of a continuous roll of copying paper in. connection with a copy protjlucing platen. Devices hitherto employed for a similar purpose have been more or less complicated and expensive.

My present invcntionis intended, inres )ect tothe class of devices mentioned, to combine conmlete practical elliciency with simplicity and cheapnessl In the accompanying drawings, which form a ,u rt of this application, Figure l is a front; elevation of a portion of a No. (5 Rentington t cwriter, shown merely by way of illustration, together with myinvention operatively applied thereto. Fig. ll is an end elevation. of the subject; matter of Fig. l illustrating the operation of my invention.

Referring to the numerals on the drawings, 1 ir'ulirates one terminal bracket support and 2 another. llach is adapted to be secured, as by screws 33, to a frame t of the typewriter. These supports are substantially identical one with the other, and both 'are provided with coalined journal bearings t),

in which an axle T is rotatablv supported.

8 indicates a platen of the machine, mounted in any usual or preferred manner in the'frame l, the ty mwriter illustrated being a No. ti Remington, but that is merely selected for the purposes of explication as my invention is applicable to any form of typewriter, with. such structural changes as the form of the typewriter in question may res quire, the principle of my invention eontinning unchanged independent of structural details.

The bracket supports l and 2 are provided with slots or slip bearings it) and ll, respectively, which are adapted to aceonnnodate, and preferably to removably accommodate, a stationary knife, which preferably consists of a blade l2 and a back or st ill'ener lit. 'lho stitfeneenmy be made in tubular form, bent;

to engage opposite sides of the. blade and to stn'r 'iort it rigidly in position.

An important feature of my invention is found in mounting the knife 12 and the axle 7 in parallel relationship and in close contiguity, though preferably the 'contignity of those members is not so close as to permit them to touch each other, nor even to per unit the knife to touch any roll of paper that may be mounted upon the axle 7.

By reason of the close contiguity of the members 7 and 12, provision of the simplest sort is made for enabling the platen 8 to constitute a direct feed for the copying paper wound in a continuous roll 15 upon the axle 7. The reason is this. The copying paper, passing trom the roll 15 around the platen 8 in a loop 16, is drawn up between the knife 12 and the roll 15. By placing the roll and the knife in close eontiguity, the paper is caused, in ell'ect, to hug almost the entire periphery of the )laten 8, which may, there fore, be depended upon to impart movement to the paper, drawing it oil from the roll 15 and passing it; above the edge of the knife 12 in the usual step by step movement, or other rotative movements of the platen. Moreover, the copying paper is by this means made, in ell'ect, a close 'litting covering for the platen, whereby the lettei 'sheets, separate or continuous as preferred, may be employed in connection with my invention for manifolding.

The knife 12 is provided in order that sce tions of the copying sheet may be severed when, and as often as required, by simply drawing a projecting portion of the sheet across the edge of the knife I2 and tearing it oll in the usual manner. in practice the severed portion of the copying sheet would be such as accommodates the copy of the letter or other separate item of written Inat ter. 'lhis tearing oll' of a sl; at of copy -may be accomplished without interfering or carbon.

fitting sleeve of coating of copying material As often as a face of the-platen 8, it will, in addition to its usual function, produce animpression upon the copyingsheet that is passed around the platen, by reason of the presence of the car bon coating upon the platen. The copy produced upon the copying sheet is, of course, negative, but it is entirely practicable to renderthe copy legible, through the employment of paper for the copying roll of suflicient thinness -to expose the marks u on it to be read from the Lher side from t at upon which the marks of the carbon copy actually appear.

What I claim is: The combination with a typewriter frame and a rotative platen, of a pair of terminal bracket supports removably secured to the key of the machine strikes the l typewriter frame at opposite ends of the l platen, said supports being provided respectively with a {ournal bearing and With a slot, a paper-r0 l-supporting-axle removably mounted in said journal hearings to rotate in a direction the reverse of that of the platen, and a knife reinovably mounted in said slots, the paper-rollsupporting-axle and I the knife being in such close contiguity as to confine the paper, drawn from the paperroll-supporting-axle and carried about the platen under the knife, in contact substantially With the entire peri hery of the platen. In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses.
