1 Claim.

This invention relates to a carbon paper pack for use with a manifolding typewriter in which a series of sheets of carbon paper forming parts of different packs are each connected to a separate supporting bar or blade of a movable carbon paper carriage and interposed between continuous sheets of paper on which several typewritten records are to be made, the carbon paper carriage being withdrawn after each typing operation to remove the carbon sheets from between the record sheets and permit tearing off the typewritten records from the continuous record sheets, and it has for its purpose to afford a carbon paper pack which can be readily attached to the supporting bar of the carbon paper carriage and includes a multiplicity of folded sheets of carbon paper arranged so that the outermost sheet can be easily drawn from the pack and unfolded for use between two record sheets while the reserve folded carbon sheets are maintained in their superposed and folded relationship in the pack, and efiectively protected so that the operator's fingers do not come in contact with the exposed carbon surface and the carbon sheets are protected against contact with the record sheets during movement of the carbon paper carriage.

A further purpose of the invention is to provide a construction in which a multiplicity of folded carbon paper sheets are attached at one end to a backing sheet, while they are protected and attached to the supporting bar of the carbon paper carriage by means of a wrapper which extends over the exposed carbon surface of the outermost carbon sheet and around the side edges of the folded carbon sheets, thence over the outer face of the backing sheet to which the wrapper is attached, leaving the folded carbon sheets free to be individually unfolded and drawn from the pack, while one end of the wrapper extends beyond the folded ends of the carbon sheets and is folded back upon itself to afford a flap that is engaged with the supporting bar of the carbon paper carriage, or is otherwise detachably associated with the supporting bar.

A further purpose of the invention is to afford a structure which is economical and simple to produce and in which the carbon sheets can be readily manipulated for use by the operator, and with a minimum waste of carbon paper.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being 2 pointed out in the claim following the specification.

In the drawings:

Fig. 1 is a plan view of a carbon paper'pack constructed in accordance with a preferred embodiment of the invention, and illustrating it in position on a supporting bar such as forms part of a carbon paper carriage of a manifolding typewriter;

Fig. 2 is a view in rear elevation of the carbon paper pack;

Fig. 3 is a view in elevation of the carbon pack, showing the outermost carbon sheet partially withdrawn from the pack as when it is to be used between record sheets, the lower part of the partially removed carbon sheet being broken away;

Fig. 4 is a similar view showing the outermost carbon sheet entirely withdrawn from the pack for use, its forward part being broken away and the next carbon sheet in position to be grasped and withdrawn;

Fig. 5 is a longitudinal central sectional view, partially broken away, on line 5-5 of Fig. 1 looking in the direction indicated;

, Fig. 6 is a transverse sectional view, partially broken away, taken on the line 6-6 of Fig. 1 and looking in the direction indicated, and

Fig. '7 is a plan view of the Wrapper before being folded around the carbon paper sheetsand attached to the backing sheet.

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughout the several views, the structure shown, which indicates one way of carrying out the invention, comprises a series of carbon paper sheets I each folded outwardly upon itself with its carbon surface exposed. The several carbon paper sheets folded in this fashion have their rear ends alined and attached to a paper backing sheet 2, see Fig. 5, which latter has a portion 3 folded around the alined rear ends of the carbon paper sheets and secured thereto by a line of stitching 4 which attaches the carbon paper sheets to the backing sheet 2. By referring to Fig. 5, it will be noted that the forward end of each folded carbon sheet terminates a short distance from the line of stitching 4 so that the carbon sheets can each be readily grasped at its forward end and withdrawn from its position over the reserve supply of carbon sheets when it is to be placed in use.

In order to protect the exposed carbon-coated face of the outermost carbon sheet from contact with the fingers of the operator and to hold 3 4 the reserve supply of folded carbon sheets in bon pack so that the operator can grasp the proper relation to each other until each is withcentral portion of the forward edge of the outerdrawn from the pack for use, there is provided most carbon sheet and withdraw it from the a wrapper of paper or other suitable material wrapper in the manner illustrated in Fig. 3 that preferably surrounds the folded carbon 5 which shows the outermost carbon sheet parsheets and backing sheet, extending around their tially withdrawn.
