MANIFOLDING- ATTACHMENT FOR TYPEWRITER S.

Application filed. December 8, 1921. Serial No. 520,836.

To all whom it may concm:

Be it known that 'I,MALooLM L. Cossrr'r,

a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Manifolding Attachments for Typewriters, of which the following is a specification.

My invention relates to that class ofmanifolding attachments for typewriters and like type-impact machines, in which a manifolding member carried by a pair of spaced arms movably mountedupon the platen-carriage of the machine is adapted to be placed in and removed from a functional position between the sheets of paper,- in the line of type-impact. a

My present invention has for its main object the use of a relatively extensive sheet or strip of manifolding material associated with the attachment and stored in small compass in a manner adapting it to be drawn out to expose for use a limited transverse section, said section being torn or-cut off when exhausted, and a fresh section drawn out and brought into use. a

The manifolding sheet or strip may be of any suitable material, though in its most practicable form it is what is known as carbon paper, as such paper lends itself both for efiiciency and economy, to the best results. 7

The nature of my invention, in several forms and modifications will be clearly ascer- 35 tained from the following description, as

illustrated by the accompanying drawings; though it is to be understood that changes in these formsmay be made within the scope of the appended claims, without departing 40 from the spirit of the invention. 1

In the drawings V Fig. 1 is a front elevation of my manifolding attachment, showing one of the manifolding-member carriers moved down, and a section of the manifolding member drawn out to position in front of the platen of the typewriter, the other carriers being in elevated position, out of use.

ted lines showing the movement of said carfor the manifoldingmeinb'ers, mounted on the carying arms ina position adapting the manlfoldlng sheets to be drawn up to funct onal posltiominstead of'down, as in preceding figures.

Fig. '7 is an enlarged sectional detail ofthe Fig. Sis an end vlew, showingthe storing of the manifolding members in rolls onthe carrying arms.

Fig. 9 is an enlarged sectional detail of the arrangement of Fig. 8.

I have herein shown as one form of a manifolding-attachment, a pair of standards-1 adapted for connection with the car riage 9 of the platen 9 of a typewriter. Be-

tween the standards are mounted a plurality of nested sleeves 2, each independently rotatable and each carrying a pair of arms 3, which are adapted for arcuatemovement.

Extending between and carried by each pair of arms is a chambered member which in one form isa casingt having an opening ,5 in its front fitted with a guide roll 6. Fig.

4:. Withinthe casing 4 is stored, in fan fold shape, Fig. 4, the manifolding member 7, which, as above stated, is preferably a relativly long sheet or strip of carbon-paper, adapted to be drawn out through the opening 5. Between the extremities of the pair of arms is a slitted rod 8 through which the carbon paper is drawn, F ig; 4. When out of use the arms are thrown up out of the way. But when a single carbon copy is required, one pair of arms are thrown down to a position shown in Figs. 1 and 4, and, the

carbon paper 7, being drawn out from the casing 4 and passed through the slitted rod 8, as in Fig. 4, presents a relatively narrow transverse section 7 in the line of type-impact.

When this section 7 of carbon paper is used up, it is torn off against the rod 8, and a fresh section is drawn out for use, and this continues until the store of carbon paper within thecasing is exhausted, whereupon a fresh store is supplied, the casing being formed with a cover 4 to permit access to its interior. Fig. 4.

If plural copies are to be made, plural arms are moved down to functional position, as indicated by the dotted lines in Fig.2.

In Figs. 6 and 7, wherein similar numerals indicate similar parts, a modification'is shown in which the carrying arms 8 are somewhat lengthened, so that the casings A may be reversed with respect to their delivery sides, and may be carried far enough below the line of ty'peim'pact to adapt the carbon paper to be drawn up, instead of down, into functional position, as clearly shown in Fig. 7. e y

In Figs. 8 and 9 a form is shown in which the carbon-paper instead of being housed within a casing, is carried by a member in the form of a reel or "roll 10,'mounted on the arms. The roll lOmaybe above orbelow the line of type impact, though for illustration I have shown it above, and the carbon paper passing down through two slitted rods 8. y

In Fig. 5, I show a simple means for releasably'lockin'g the carrying arms, consisting of the spring-pressed balls 11 coacting with said arms.

1.. A manifolding attachment for typewriters comprising a carrying member; means for mounting said member on the platen carriage of the machine, adapting it for movement towards and away from the line of type-impact; a chambered member mounted upon said carrying member; and a manifolding sheet within said chambered member and adapted to be drawn therefrom to present successive sections in the line of type-impact.

2. A manifold'ing attachment for typewriters comprising a pair of spaced arms; means for mounting said arms upon the platen-carriage of the machine adapting them for movement towards and away from the line of type-impact; a carrying member secured to said arms; and a manifolding sheet carried by said member and adapted to be drawn therefrom to present successive sections in the line of type impact.

3. A manifolding attachment for typewriters comprising a pair of spaced arms; means for mounting said arms upon the phla'en carniage of the machine adapting them for movement towards and away from the line of type-impact; a carrying member secured to said arms; a manifolding sheet carried by said member and adapted to be drawn therefrom to present successive sections in the line of type impact; and means carried by said. arms for holding the free end of the drawn out section.

4. A manifolding attachment for typewriters comprising a pair of spaced arms; means for mounting said arms upon the platen-carriage of the machine adapting them for movement towards and away from the line of type-impact; a carrying member secured to said arms; a manifolding sheet carried by said member and adapted to be drawn therefrom'to present successive sections in the line of type impact; and a slit'ted rod carried by said arms, through which the free end of the drawn out sec tion is passed and against whichsaid section is torn off.

5. A 'manifol'ding attachment for typewriters comprising an apertured casing; means for mounting said casing-on the platen carriage of the machine; and a. 'mainfol dingsheet fan-folded within said casmg and adapted to be drawn therefrom to present successive sect-ions in the line of type impact.

6. A manifolding attachment for typewriters comprising an apertured casing;

means for mounting said casing on the platen carriage of the machine, adapting it for movement towards and away from the line of type impact; and a manifolding sheet fan-folded within said casing and iulapt'ed to be drawn'therefrom to present "successive sections in the line of type impact.

8. Amanifolding attachment for typewriters comprising a pair of spaced arms;

means for mounting said arms upon the platen carriage of the machine adapting them for movement towards and away from the line of type impact; an apertured casing carried by said arms; manifolding sheet fan-folded within said casing and adapted to be drawn therefrom to present successive sections in the line of type-impact; and means carried by holding the free end of the drawn out section.

9. A manifoldin'g attachment for typewriters comprising'a pair of spaced arms;

said arms for means for mounting said arms upon the platen carriage of the machine adapting them for movement towards and away from the line of type impact; an apertured casing carried by said arms; a manifoiding sheet fan-fo1ded within said casing and adapted to be drawn therefrom to present successive sections in the line of typeimpact; and a slitted rod carried by said arms, through which the free end of the 10 drawn out section is passed and against Which said section is torn off.

In testimony whereof I have signed my name to this specification.

MALCOLM L. COSSITT.
