Since the coating is continucus c- -fE view cf transfer 01' feIentia-iiy, it-WiL transfer inscriptions e llii ously upon any desired length of record web.

Since the platen 11 is preferably mounted upon the typewriting machine so as to be readily removable, it is a simple matter to exchange it when the transfer coating becomes depleted. When the coating 18 of transfer material becomes exhausted so as to fail to transfer a good copy to the translucent web 15, it will be practicable to replace the platen with another having a fresh coating of transfer material. The coating of transfer material may be applied to the platens in any convenient manner. One or more freshly coated platens may be kept at hand for replacing those upon which the coating has become exhausted. It is also practicable to utilize platens having differently colored transfer coatmgs.

With the arrangement described, the duplicate copy is made upon the translucent web 15 without the use of separate carbon sheets. Therefore, a considerable saving in material, time and labor is accomplished and the arrangement and adjustment of loose carbon sheets is entirely avoided. It will be obvious that short or loose record sheets may be utilized instead of the continuous forms 14 and 15, ,as shown, and the original or outer sheet may be opaque, while the inner sheet is translucent.

Instead of being coated upon the outer surface of the platen as above described, the web supporting or surfacing cylinder 17a, as shown in Fig. 3, may be of porous material, such as a fibrous composition or porous rubber, which is capable of absorbing the carbon or transfer material which is applied thereto. This web supporting cylinder is then impregnated or permeated with the transfer material. The supporting cylinder 170, may, in this manner, carry a larger amount of transfer material and, therefore, is capable of transferring a greater amount of inscription before becoming exhausted. In this case, as in the embodiment above described, the inscriptions will be transferred by the action of the carbon-saturated supporting cylinder 17a to the back face of the record web resting against the cylindrical surface. This web may, as already described, be of translucent material. The saturated cylinder l'la may be removably mounted upon the platen whereby it can be conveniently replaced by another. These cylinders may be impregnated with different colors or different qualities of transfer material.

Another manner of applying the transfer material to the web supporting surface is suggested by the embodiment shown in Fig. 4. According to this form. the platen 11 may be of usual or standard construction, a sheet 19 of transfer material being wrapped tightly therearound, having its transfer surface or carbon coating presented externally so as to contact directly with the record web as in the prior embodiments described above. For supporting the transfer jacket or sleeve 19 in position, securing means may be provided such, for example, as retaining rings or bands 20. These retaining bands may be of appropriate material, either rigid or elastic, and proportioned to slip snugly over the transfer sleeve to retain it in operative position upon the platen. The edges of the transfer paper may overlap circumferentially to any desired extent and the transfer sheet may be wrapped one or two or more times around the platen. When the transfer sheet extends two or more times around the platen, a fresh transfer surface may be presented by tearing off the outside layer. This may be done by tearing or severing the outer layer along circumferential lines adjacent to the inner edges of the retaining bands 20 and these bands may serve as tearing edges for assisting in such severance. The sheet may be additionally weakened or perforated along the severance lines. If plural wrapping is used the sheet stack may be quite heavy, thus protecting the underneath layers of carbon while the outer layer is in use.

A form of transfer sheet 21 for application to a platen is disclosed in Fig. 5. This sheet is substantially as long as the platen and wide enough to extend entirely around the platen and to overlap circumferentially sufficiently at the edges thereof to secure the sheet in position upon the platen. The back or non-coated face of the sheet is provided along one edge thereof with an adhesive 22. This adhesive may be moistened in applying the sheet around a platen. The adhesive will then be pressed against the sheet at its opposite edge causing the two edges to adhere so as to hold the transfer sleeve thus formed in position upon the platen.

According to the embodiment shown in Fig. 6, a sleeve or jacket 23 is provided, being coated on its outer surface with transfer material. This sleeve may be of paper or other fibrous material and is preferably integral throughout its length and circumference, thus avoiding all seams. It is sized to slip snugly in position over the platen and when thus positioned it functions to transfer inscriptions to the record webs as already described.

The embodiment of Fig. 7 is similar in principle to the foregoing embodiments, but in this case the platen 24 is of the flat type and the coating 25 of transfer material is applied thereto, as suggested in the foregoing embodiments, so as to transfer the inscriptions directly to the back face of the record web lying against the platen. The transfer coating 25 may be in the form of a sheet and can be secured in operative position by clamping means such as marginal clamping bars, one of which is shown at 26. In case the transfer material is coated directly upon the platen surface,

said platen 24 may be removable and held in position by the clamping bars 26; it is thus conveniently replaceable at will. The record strips are superposed in manifolding relation upon the surface 25 and can be inscribed with pencil or stylus, or with type bars of a writing machine, with the transfer result as described above. In this embodiment as well as in the others above referred to it will be understood that the carbon transfer material, as in the case of the well known carbon transfer paper, is in set condition upon the platen surface or impregnated therein.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A platen for manifolding machines having a web supporting zone thereof formed of porous rubber impregnated with transfer material in set condition.

2. A platen for manifolding machines having a
