This invention relates to carbon transfer sets for use in connection with. typewriters, calculating and' tabulating machines and ofce recording machines, of a. similar nature wherein a plurality of superposed record sheets are used with the sheets of the carbon transfer set suitablyinterleaved.

It is a general object of the invention to provide a carbon transfer set of the class mentioned having improved features of construction adapting it for more effective use in connection with the positioning of the carbon or transfer sheets in interleaved transfer relation with record strips of the long continuous traveller type and. which, moreover, is of such a simple structural nature that it may be expeditiously manufactured with a minimum o-f production costs..

A further object of the inventionis to provide a carbon transfer sethaving an improved structure and arrangement of the transfer sheet supporting elements whereby it may be conveniently used in connection with long continuous record strips of the fan-folded type as well as with long continuous record strips which are separate and distinct from each other.

Other objects of the invention will be in part pointed out in the-detailed description below of an illustrativev but preferred embodiment of the invention, and will be in part obvious in connection therewith.

According to the invention the transfer set comprises a backing sheet having a holder part and a series oftransfer sheet supporting members, which may be blades, hingedly connected to a side margin of the holder ,so that they can be swung about their hinges clear of the holder.

Each supporting blade or the like serves as a holder for a carbon sheet, the latter being attached alongits top edge to the blade. The blades may be superposed or otherwise s arranged that the carbon sheets are superposed for transferring inscriptions to the record sheets or strips. Preferably each blade extends completely across the carbon sheet so that the latter is rigidly supported over its full transverse length, but the width of the blades and the corresponding carbon sheets may vary in any given transfer set. The `carbon sheets are of any desired length and preferably all the sheets of the set 0 are of the same length, that is to say their free lower edges are in register.

For a more comprehensive understanding of the nature and objects of the invention reference is had to the following detailed description of the illustrative preferred embodiment of the 1n- Cil vention, and to the accompanying drawing in which: l

Fig. 1 is a plan view of a transfer set embodying the invention.

Fig. 2 is an end view of the article shown in Fig. 1 showing how the carbon supporting members are interleaved, and

Fig. 3 is a verticalr section along the line III-III of Fig. l, looking in the direction of the arrows. y

Referring to the Vdrawing for a detailed description of the embodiment of the invention there shown.' the transfer set comprises a holder sheet I, to the opposite marginal edges 2 of which are secured supporting blades 3 by any Suitable means as for example by stitchingA 4, which may be; of textile thread, light flexible wire,` wire staples clinched at their free ends, or like means. The upper end 5 of. the holder sheet is reinforced by the bar l' having opposite lateral extensionsV to form stops l for the purposev hereinafter explained.. A carbon sheet 8 is xed as by an adhesive, stitching, or other known means to the lower edge!! of each supporting blade 3.

Each blade 3 may be weakened along a line 3a adjacent and parallel to the line of stitching 4 so that it may hinge easily about the holder I. The weakened hinge linesv3a may be made by creasing, scoring or perforating the blade material, or by bending so asi to crush or weaken the fibers` in cases where the blades are made of fibrous material such Vas paper, cardboard, or leather. Each blade extends completely across the carbon sheet 8 so that the latter is amply supporte-d over its full widthto ensure that the carbon sheets are held in correct register and Will withstand the action of drawngthe record sheets through the holder without displacement. The blades are shown in triangular form Vbut obviously they may be rectangular or otherwise shaped. Further it will be understood that while the blades lare shown superposed they may be otherwise arranged with the carbon sheets superposed. The carbon sheets 8 are of any desired length and are preferably arranged so that all their free ends l0 are in register.

As shown in the drawing; it is preferred to arrange the supporting blades 3 in superposed relation with each other and to attach them by means of the attaching device 4 to the opposite marginal portions of the holder or backing sheet I. kEach of the attaching devices 4 extends along one of the longitudinal marginal portions of the backing sheet i and is positioned at parts of the supporting blades which are overlapped with the of the device, or

iranged in superposed relation with 'although it will be understood that more than marginal portions of the backing sheet, thus providinglongitudinal marginal reinforcements for said backing sheet. As shown, there are two Vsupporting blades attachedat eachrof the oppositeY lateral edges ofthe backing sheet and ar"- each other,

bladesmay'b'e thus mounted .at each side in some cases only 'one supporting blade may margin, These Vsupporting blades extend fromtheir supporting Yattachments towardthe oppo,

Y' sheet are spaced at the same .distance from thel site edge of the set or device, the blades atY one side being thus interdigitatedwith thosefat the other side. supporting bladesfat each vsideof the' backing rear stop 1, and the forward edges 'of allof the bladesV are substantially flush withY each other. Y `When the carbon sheets to these forward flushY edgesofthe supporting blades a thoroughly balanced assemblage is provided. The rearward edges of the` supporting blades 3v are preferably'inclinedaas' shown and theirearward margins of thelower blades extend rearwardly slightly beyond the edges of the overlying'blades so `asto provide readyacces's at all times to all of the blades soas to facilitate their manipulation as for .example when the device is beingA threaded into position with the record strips or when it is being removed from said record strips. s With such an arrangement, in. preparing the holder for use in typing, each supportingrblade 3 carryingfal carbon sheet 8 is swungclear of the holder'l in turn while the appropriate record strip or sheet I2 .(seeFigf 3) is introduced be- Vneath it, Ythe .blades Y,then being'- turnedY down 5 dash lines inFig. 3.
