it has for its principal purpose to afford a, structure including a holder that can be permanently fastened to a supporting bar of the carbon paper carriage and a carbon paper pack that is detachably associated with the holder whereby the carbon paper pack can begrenewed whenall of the carbon paper sheets are used by detaching the carbon paper pack from the holder, without the necessity of removing the holder or otherwise disturbing the relationship between the holder and the supporting bar. A further purpose of the invention is to aflor a construction adapted for convenient use with a carbon paper pack consisting of a multiplicity of sheets of carbon paper attached at one end to a backing sheet and each sheet of carbon paper folded upon itself and arranged flatwise, with means for detachably securing such a carbon paper pack to a holder.

An additional object of the invention is to afford a structure of simple and economical manufacture in which a multiplicity of folded carbon sheets are attached to a backing sheet and thdbackingsheet constructed so that it can be readily attached to a holder mounted on the supporting bar of the carbon paper carriage, or removed therefrom as required.

Still another purpose of the invention is to afford a structure in which a backing sheet with a plurality of folded carbon sheets secured thereto is detachably associated with a holder permanently mounted on the supporting bar and which can be easily secured to or removed from the holder by the operator while also providing means for effectively protecting the folded carbon sheets in the pack from contact with the record sheets as the carbon paper carriage is moved rearwardly of the record sheets.

A further object of the invention is to afford simple, practical, and economical construction comprising a flexible holder that may be permanently attached to the supporting bar of the carbon paper carriage and which is .so con- 6 Claims. (Cl. 2821) of the carbon pack, the backing sheet and carbon pack having provision for readily associating these parts with the flexible holder or removing them when the carbon pack is to be renewed.

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 theaccompanying drawings, the novel features being pointed out in the claims following the specification.

In the drawings:

"Fig. l is a plan view, partially broken away. showing a carbon paper pack attached to a flexible holder in accordance with a preferred embodiment of the invention, the holder being mounted on a supporting barof a carbon paper carriage; I

Fig. 5 is a view similar to Fig; 4, looking at the opposite face or toward the backing sheet of the carbon paper pack;

Fig. 6 is a side elevation, partially broken away,

broken paper P Wi h the outermost carbon sheet with drawn for use.

Referring more particularly to the drawings in which like reference numerals refer to' the same *parts throughout the several views and to Figs. 4

to 7 inclusive, the carbon paper pack includes a;

backing sheet I to which a multiplicity of carbon sheets 2 are secured at their forward edges, the forward portion of the backing sheet being folded around the forward alined ends of the carbon sheets as shown at 3 and stitchedthereto as at 4. Each carbon sheet is folded upon itself outwardly I and the free ends of the folded carbon sheets terminate in spaced relation to the line of stitchreserve carbon sheets which, are not in. use are retained in the pack, only one carbon sheet being 3 used at a time as usual in this type of construction.

The carbon sheets may be attached to the backing sheet I in other ways than as specifically herein shown and described, and the backing sheet is preferably of sufficient length to extend around the folded ends of the carbon sheets and to afford a protective cover or flap 5 that overlies the exposed carbon surface of the outermost carbon sheet, as illustrated in Fig. 6.

Various types of carbon paper packs have been deta-chably associated with'a holder, including a pack consisting of a continuous sheet of carbon paper wound around a support, but there has not been heretofore available a structure for detachably mounting on a flexible holder a. carbon packcomprising a multiplicity of individually folded carbon sheets arranged flatwisa'which'is a most convenient and desirable type of carbon pack, and the present invention has to do with detachably mounting such a carbon-pack on a-flexible holder that can be permanently attached to a supporting bar of the carbon paper carriage.

In order to accomplish this, the backing sheet I of the carbon pack has attached thereto a cardboard strip that is stitched to the backing strip along the line 6, see Figs. 5 and 6, the cardboard strip being free from the backing strip except at the stitching line 6, and including an elongated tongue I preferably extending across the width of the backing sheet and cut away at its corners as indicated at 8, while 9 designates a finger having tapered sides I and arranged centrally of the portion II forming part of the cardboard strip, the tongue I and finger 9 constituting the means for detachably associating the backing sheet of the carbon pack with the holder which will now be described. It is also within the purview of the invention to form the tongue land finger 9 as integral parts of the backing strip; which may be attached directly to the holder, without the necessity of a separate cardboard strip.

The holder is preferably constructed of canvas or other suitable fabric and includes a body portion I 2 folded upon itself to afford a loose flap I3 that overlies the outer surface of the carbon pack when in operative position, the portions I2 and I3 of the holder being stitched together at I to afford a hem or loop that receives thesupporting bar I5 of the carbon paper carriage. When the flexible holder is once mounted on the supporting bar I5 by sliding the latter through the hem or loop, the flexible holder-remains permanently'thereon and the carbon paper pack is detachably mounted on the holder as will now be described.

To accomplish this, the opposite end of the I flexible holder is folded upon itself as indicated at I6, and I1 designates a band extending across the flexible holder and spaced slightly therefrom as shown in Fig. 3, the ends of the band I! being folded between the body portion I2 and the folded portion I6 of the holder, as indicated at I9, and adhesively secured in such position, so that the band I! is permanently located in relation to the holder as illustrated, while I9 designates a slot formed in the folded portion I6 above the band I I.

The folded portion I6 is adhesively attached to the body portion I2 of the flexible holder at the lower portion below the band I! and along its upper edge above the slot I9, but is free from I the body portion I2 immediately adjacent to the slot I9'in order to permit insertion through the 4 slot of the finger 9, which lies between the body portion I2 of the holder and the folded portion I6 when the carbon paper pack is attached, as shown in Fig. 1, while the space between the band I! and the folded portion I6 of the holder is occupied by the elongated tongue 1.

In order to attach the carbon paper pack to the holder, the flap I3 is swung outwardly to permit access to the band I I and slot I9. The carbon paper pack is then positioned over the holder with thetongue I and finger 9 in position for insertion under the band I! and into slot I9 respectively. The elongated tongue I is first in serted under the band I! and between the band I! and the folded portion I8 of the holder, after this point so thatthe tongue can be inserted readily between them, and it will be understood that the tongue 1 and finger 9 being portions of a cardboard element are sufficiently flexible so that they can be bent sufflciently for insertion into their respective locking positions without permanent distortion. When the tongue I and finger 9 have been thus inserted, as illustrated in Fig. 1, the carbon paper pack is securely mounted on the holder which in turn is permanently mounted on the supporting bar I5, and the pack is in position for withdrawing the carbon sheets successively to operative position. When all of the carbon sheets in the pack have been exhausted, the carbon pack is removed from the holder. by bending finger 9 sufilciently to withdraw it from the slot I9 and then elevating the tongue I from behind the band H. In this fashion, the carbon pack is removed and a fresh pack can be inserted.

While the invention has been described with relation to the particular construction shown, it

is not restricted to the details herein disclosed and this application is intended to cover such modifications or departures as may come within the purposes of the invention and the scope of the following claims.
