Description

Filed April 28. 1930 Patented Mar. 22, 1932 PATENT OFFICE CHARLES L. KELLY, OF CHICAGO, ILLINOIS, ASSIGNOR TO CONTINENTAL CARBON CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS CARBON PAPER HOLDER Application filed April 28,

The present invention relates to carbon paper holders, and more in particular to the provision of a novel construction adapted for use in typewriters and similar machines. The construction disclosed in this application is an improvement upon that shown in my Patent No. 1,743,820, granted January 14, 1930.

In constructions of carbon paper holders, prior to that of my patent and the present application, the carbon paper was secured to the backing strip and no provision was made for detaching the carbon sheets, nor was any provision made for the addition or subtraction of the number of sheets with which the holder was provided. In such rior constructions, the backing strip and caron sheets, when once assembled, became a permanent structure, and when the carbon was no longer of use, or when the attaching means became broken or disengaged, the entire holder was necessarily discarded.

Among the objects of the present invention are to provide a carbon paper holder for receiving a plurality of pieces of carbon paper intermediate of which are placed sheets of letter paper, the holder being so constructed that the entire assembly may be readily and easily inserted into a typewriter or similar machine.

A further object of the invention is to provide a novel construction of backing sheet for a carbon paper holder, the same being provided at its upper end with a folded portion formed' integral with the backing sheet, the fold providing a means for intercepting and alining an edge of the carbon paper. By reason of the integral construction of the backing sheet and the folded portion, no difficulty is encountered in feeding the holder with its retained sheets into a proper position in the typewriting machine.

A still further object of the invention is to provide a carbon paper which has suitably spaced openings adapted to be alined with 1930. Serial No. 447,856.

similarly spaced openings in the backing sheet and the folded strip. Another object is to provide a novel construction of interlacing member formed of a flexible material and provided at its end with a rounded tip portion, the central portion thereof being formed of a greater width than the remaining portion. This flexible interlacing member is so constructed that the ends thereof may be entered and interlaced through the central aligned openings in the front or folded strip, carbon and backing sheet, the ends then being adapted to be interlaced or interce ted in the openings adjacent the opposite e ges of the folded portion, carbon and backing sheet. This detachable interlacing member not only provides means for assembling the folded portion, carbon and backing sheet, but it also provides an abutment for the letter paper that is to be inserted in the carbon paper holder. The enlarged centralportion of the interlacing member also prevents any lateral shifting or displacement-thereof when the parts have been placed in assembled relation.

Referring more particularly to the disclosure in the drawings, the assembled carbon paper holder is designated generally as 1, and includes a backing sheet 2, having its upper end folded to provide a top strip 3. Intermediate the top strip and backing sheet is provided carbon paper 4. The carbon paper when inserted intermediate the top strip and backing sheet, strikes o-r abuts against the fold and is thereby properly positioned. This backing sheet is ordinarily constructed of heavier composition than the ordinary paper and may consist of oil paper or other suitable and desirable material, and is generally of the same width as the carbon sheets so as to facilitate the assembly of the carbon and backing member. A plurality of suitably spaced openings 5 and 5 are provided in the upper strip 3, carbons 4 and backing sheet 2. These openings are of a substantial width and the openings in the upper strip, carbons and backing sheet are equally spaced so that these openings may be placed in alinement for the insertion of an interlacing member.

The top strip 3, carbons and backing sheet are held together by means of a flexible interlacing member 6. This member may be constructed of any suitable flexible material,

such as celluloid or other material having the characteristics thereof. The end portions 7 of the interlacing member are rounded so as to facilitate their insertion through the alined openings in the top strip, carbons and backing sheet. Intermediate of the end portions, is provided a portion 8 of substantially greater width which provides a gripping means when the interlacing member is bent and inserted through the alined openings 5, the ends 7, 7 being inserted initially through the central openings 5 and from there to the openings 5 adjacent the edges of the carbon holder.

Further objects are to provide a novel construction of maximum simplicity, etliciency, economy and ease of assembly and operation and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the combination, construction and arrangements of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, without departing from the spirit of my invention.

In the drawings:

Fig. 1 is a plan view of the carbon paper holder.

Fig. 2 is a view in vertical cross section taken on the line 22 of Fig. 1, the sheets of writing paper having been removed.

Fig. 3 is a fragmentary view of the backing sheet and the integral top strip which is folded over the sheet.

Fig. 4 is a view in horizontal cross section of the holder taken on the line 4-l of Fig. 1, and showing the means of assembling the backing sheet, top strip and the carbon paper.

Fig. 5 is a fragmentary view in rear elevation of the assembled holder. showing clearly the end of the interlacing member in position.

Fig. 6 is a. view in perspective of the interlacing member.

After the interlacing member has been placed in position, the same can only be removed by the operator grasping the widened portion 8 and pulling the member from the holder. W'hen assembled, the interlacing member cannot be shifted laterally since the widened portion 8 is of a length substantially the distance between the central openings in the carbon paper holder.

The letter paper 9 is inserted between the sheets of carbon paper until the same abut against the lower edge 10 of the interlacing member. This edge 10 provides an abutment and means for alining the letter paper in the holder. Any number of sheets of writing pa- -per may be inserted, depending upon the number of sheets of carbon paper that are detachably held in the carbon paper holder. By reason of this construction, the stenographer can arrange the desired number of carbon papers in the holder in the morning, and will not have to change the same throughout the day for any letters requiring the same number of carbons. If it is desired to prepare a less or greater number of carbons, any carbon papers may be subtracted or added to the number in the holder. It is a simple matter for anyone to remove the interlacing member and to change the number of carbon sheets in the holder.

By reason of the unique construction of the holder the assembly may be easily insertcd into the typewriter or similar machine, and there is no danger of the assembly becoming disengaged. Also, by reason of the construction, the parts may be readily alined and kept in such alinement.

From the above description and disclosure, it will be readily seen that I have provided a construction having the advantage of cheapness and simplicity, one which is highly efiicient, may be readily assembled and disassembled, and one which will give a maximum period of use.

Having thus disclosed my invention, I claim:

1. A carbon sheet holder comprising a backing sheet for a plurality of removable superposed carbon sheets, an edge of said backing sheet being folded upon itself to provide means for intercepting and aligning an edge of said carbon sheets, a flexible member arranged transversely of said backing sheet and having a removably interlaced engagement with said folded portion, carbon sheets and backing sheet so that the holder may be readily inserted in a typewriting machine, and positioning and aligning means on said member for preventing lateral shifting of the member in its interlaced engagement.

2. A carbon sheet holder comprising a backing sheet for a plurality of superposed carbon sheets, an edge of said backing sheet being folded upon itself to provide means for intercepting and aligning an edge of said carbon sheets, and a flexible member arranged transversely of said backing sheet and having a removably interlaced en agement with said folded portion, carbon slieets and backing sheet so that the holder may be readily inserted in a typewriting machine, said member being provided with an enlarged central portion for properly aligning and positioning the same in interlaced engagement and for preventing lateral shifting thereof after the holder has been assembled.

3. A carbon sheet holder comprising a backing sheet for a lurality of super osed carbon sheets, an e ge of said sheet ing folded upon itself for the reception and alignment of said carbon sheets, said backing sheet, folded portion and carbon sheets being provided with suitably spaced and ali ed openings, a detachable interlacing inem r ada ted to be passed through said 0 enings or holding said backing sheet, fol ed portion and carbon sheets in assembled relation, and a projection on said member for roperly positioning the same in its interlac engagement.

In witness whereof, I hereunto subscribe my name to this s ecification.
