To all whom. it may concern.

Be it known that I, GEORGE WV. DONNING, a citizen of the United States, residing at Stamford, in the county of F airfield and State of Connecticut, have invented certain new and useful Improvements, in Type \Vriters, of which the following is a specification, reference being had therein to the ac eompanying drawing.

This invention relates to typewriters and, particularly, to structures employed in conjunction therewith for supporting and positioning manifolding material in relation to the platen forming a part of said typewriter.

The object of the invention is, primarily, to provide a. manifolding element adapted to be supported and positioned, at the will of the operator, in relation to the platen, and to combine therewith simple and easilyananipulatcd means for actuating said ma ni fu filll"-0l'l]10llt whenever. necessarywhether it on for the purpose of presenting a reiativclv ditferent surface in position for operation, or for bodily changing its position in relation to the platen.

in a more specific aspect, the invention includes carl'ion -supporting means sustained by parts of the machine other than the carriagesupporting rails forming a part of said machine.

The present case is a true divisionof an application filed by me June 6th, 1899, Serial No. 719,623, for improvements in typewriters, and which has now eventuated in Patent No. 970,195, dated September 13th, 1910, and is directed to subject-matter expressly carved out of said application, In that case, the subject-matter comprchends, among other structure, manifolding-devices in which the carbon-sustaining devices are supported, particularly, in relation to or on the carriage-supporting rails or'guides.

As before stated, t-he-subject-matter of the.

present case has relation to manifoldingdevices in which the supporting-structures therer'or are distinct from said rails or guides, in the sense that they are independent thereof. One embodiment of such structure contemplates the provision of supporting-devices carried by or disposed adjacent to the 'laten'of the machine. In tieaccompanying drawings, I have illustrated some of the embodiments of my invention and, in said drawings: Figure 1 is a view in perspective showing one form of ty )ewriting-machine in which my invention is embodied; Fig. 2is a similar View of one form of platen detached from the machine, and to which is attached a form of device for supporting and positioning a manifolding-elenient; Fig. 3 is a'similar view of one form of platen with which is mounted a different form of device-for supporting and positioning a manitoldirig-element; Fig. 4- is a similar view, showing the forms of n'ianifolding-dcviccs shown in Figs. 2 and 3 combined, whereby a. plurality of copies may be produced at one writing; and Fig. 5 is .a similar view of a modified form of structure, wherein the carbon-supporting and p0- sitioning device is independent of the platen and track-frame and is shittablc over the latter and t-iltable relatively thereto.

In these drawings: The numeral 1 designates a platen which, in this instance, is of the so-called flat-platen form. It may, if desired, be t-iltable and, to this end, would be pivoted at one edge, as at 2.

Underlying the platen is a supportingstructure 3 which, in some instances, (as in the present), is adapted to sustain a trackframe 4 upon which is mounted a printingmecha'nism 5. The track-frame, in this instance, is shown, by way of example, as tiltable, and, to this fond is hinged, as at 4.

In Fig. 1 a taveling book-supporting structure 6 is shown, booksustained thereby is shown as extending across the platen;

As illustrated in Fig. 1 and, on a larger scale, in Fig. 2, the platen 1 is provided with carbon-carrying members, spindles, or rolls 8, 8, rot atably mounted in brackets 9, 9, beneath the forward and rear ends of th platen. Each of said carrying-members 8 18 provided with a knurled head Or portion 10, respectively, and whereby said members may be rotated by the operator. It

will be understood that carbon, or any other and a page 7 ot' the appropriate form of inanifolding material,

or sheet over the operative surface of the. platen. By these means, as will be readily understood, the carbon-sheet or other form of manifold-ing-element may be supported and positioned over the platen. To facili-- tate these operations, the platen may be provided, adjacent the carrying-members and parallel therewith, with elongated slots or apertures 11, 11, through .which the manifolding-sheet or ribbon readilypasses.

Iii-Fig. 3, l have shown another form or. manifoldmg-device. 12 which 15 adapted to support and position a manifolding-element or ribbon' over the operative surface of the platen: In this instance, the device comprises a frame 13 to which is secured the sheet .or ribbon of manitolding-material. Connecting with the frame is an actuatingmechanism 1+1 wherebyit may be moved (and, with it, the manifolding-element) in relation to the platen.

In Fig. 4, I have shown both of the described forms of manifoiding-deviees operatively combined; that is to say, the rotatable'form of carbon-carriers of Fig. 2 are shbwn as supporting a sheet'to overlie the platen, and the frame-form of Fig. 3 is shown as supporting its manifolding-element so as to overlie the first-mentioned manitolding-element. By these means, as is obvious, a plurality of copies may beproduccd simultaneously: The lower manifolding' element may, in this instance, rest upon the upper surface of the'platen; then asheet or book-page may be laid thereover; a second sheet or page would thenbe arranged to overlie this; and, then, the manifolding-ele ment or ribbon carried by theframe would be interposed between said second sheet and a third sheet against which the, type would strike and print. If the manifolding-element in each instance isv an inked fabric, the copies would all be ribbon or original copies. It a further copy is desired, I'

would provide a third term of manifoldingdevice 15,.in the form of a. frame 16, suitably fniounted adjacent to, but independently of the platen, as shown in Fig. It is adapted to position its sheet across the platen-- in this instance, at right-angles to the sheet. carried by the frame 12. i

To confine the Worksheets or a manifold ing-element upon the laten, one or more clamping-devices 17, 1% mav be provided ass-shown in Fig. 4. It will be understood that the frame 12 may similarly be utilized a .tiltable platen is employpd, it would, of

course, be disposed independently of the platen and so arranged that it could conveniently be positioned in operative relation to i the platen.

In Fig. 5, I have shown still another form of manifolding-device 18 which, in this instance, is a frame 19 pivotally and slidably mounted on a rod 20 journaled in upstanding lugs 21, 21, carried by a supporting member 22. In this example or embodiment, it Will be seen that the said frame may be tilted away from the platen, and, also, shifted thereover. By this means, the manifolding-element carried by the frame may be p0 sition-ed in relation to the platen in'a plurality of directions. The frame carries spindles, 23, 23, and the sheet may pass through elongated slots 24 formed in said frame adjacentto said spindles.

By the several elements disclosed, where the platen-supported spindles 8, 8 carry stationery, in the form of a work-sheet, etc., the positioning-frame may carry a inanifolding-element. Or, the platen-supported spindles would carry the work-sheet, as mentioned, the frame carry the manifoldingr-element, and the clamp-devices 17 be utilized to hold'down, at one edge of the 'platen,'one or more sheets. including carbon sheets, etc, and by which several means, also, the clamps and said carbon-homing frame could be utilized to hold down the work at a plurality of points, when necesary. lVhere the platen-spindles are thus employed to support a work-sheet, and the frame (that one, for instance, which is operated by foot-mechanism, as already described), the extensions 13, 13, could underly the carbon so as to raise it away from the platen when the work is released by the body-portimi 13 thereof.

In still another aspect of the invention,

the platen-supported spindles would carrv.

the manifolding-element, and the several clamping-devices (including the clamps 17, the frame 13, etc.) would be utilized to confine the work-sheet.

In a further aspect, the clamp 17 could be utilized to hold one or more sheets of carbon, and the carboncarrying-frame made further useful to hold the work-sheet or sheets.

Other obvious changes could similarly be made and. yet be within the spirit of my invention.

Having thus fully described my invention, its construction and its mode of operation, what- I claim and desire to secure by Letters-Patent is:
