' support for a printing surface, for use on thereof. In the form shown in Fig. 1 o

presses having a rotary printing member, which support shall be of light and rigid construction, and which is held firmly in position but is capable of being easily removed. These and. other objects of the invention will more fully appear from the following descri tion. I

T e invention consists in the novel parts, improvements and shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, the same serving in connection with the description herein to explain the principles of the invention. I

Uf the drawings: Figure 1 is a perspective view of a printing surface support; Fig. 2 is an end view of such a support mounted on the press cylinder; Fig. 3 is a side elevation combinations herein corresponding to Fig. 2; Fig. 4: is a side ele-,

vation of a press cylinder of a form adapted for use with a printing surface support, such as is shown herein; Fig. 5 is a sectionshowing forms of transverse web; Fig. 6 shows one form of attaching the printing surface to its support; and Fig. 7 is a detailed view of a portion of the mechanism.

In the embodiment of the invention illus trated herein a printing surface support 1 is shown which is in the general form of a section of a hollow cylinder. The said support is adapted for'use with a printing surface of any nature, such as relief, inta'glio or planographic. It is illustrated herein, however, as used with a planographic surface. The ma terial of which the said support is made may be of such a nature as to formpart of a planographic printing surface and may constitute the ink-rejecting or non-design art f the drawings a surface of this nature is contemplated and is indicated by the reference numeral 2. In the form shown in Fig. 6 of7 the drawings the printing surface is carried ulpon a separate plate which is mounted upon t e support in a manner known to the art. The said support 1 is provided with transverse webs 3 which may be placed at the ends of the said support and may also be placed intermediate of the ends. These webs are so disposed and proportioned as to give the plate proper rigidity against flexure or deformation from handling, or from yielding while under impression. While the said support may be thus constructed sufliciently strong in itself to withstand all pressures and strains incident to use, a form of cylinder especially designed for use with a printing surface support of this character, and which acts to take up a large part of the strain and pressure during the impression, is provided. The cylinder 1s shown with portions 4 of such radius as to fit snugly within said support 1 so as to take up the squeeze of the impression so that there may be no yielding or deformation of the saidsupport. The said cylinder is provided with recesses 5 at the ends thereof for taking in the end transverse webs 3 of the support, and where there are internal transverse webs carried by the. support transverse recesses 6 in the cylinder are provided for receiving same. These various corresponding parts are made to fit each other in an exact manner, and thus it will be seen that the cylinder 4 backs up the support l in such manner as to prevent any deformation or yielding from the squeeze of impressions and the support is also held in exact register in every respect. Holding means, in addition, may be provided and are shown as a pin 7 upon the su port 1' and hook 8 upon the cylinder 2. T e said hook may be provided with a slot 9 in which a tap num, may be deposited thereon in suitable manner, as by electro-depositipn or by dipping and a suitable design may be imposed thereon in any desired manner.

From the foregoing it will be seen that a printing surface support has been provided which is of great strength and rigidity while verse webs,

' cylinder having a at the same time ossessing great lightness; that a press cylin er has been provided especially adapted for use With the said surface support; that the said cylinder takes up directly the strain or pressure of the impres sion; that the said support is held in exact register by the said cylinder, and is yet readily removable therefrom when desired, as well as possessing other advantages.

The invention, in its broader aspects, is not limited to the particular constructions shown, nor to any particular constructions by which it has been or may be carried into effect, as many changes may be made in the construction without departing from the main principles of the invention and without sacrificing its chief advantages.

What I do claim as my invention and desire to secure by Letters Patent, is:

face support in the form of a section of a hollow cylinder and being provided with a transverse web, of a press cylinder having a portion of such radius as to fit within the said printing surface support so that the concave surface of the support rests directly upon the cylinder.
