PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 634,819, dated October 10, 1899. hpplication filed April 13, 1899. Serial No. 712,907. (1i 0 model.)

and State of Pennsylvania, have inventednew and useful Improvements in Printing- Presses, of which the following is a specification.

In certain lines of printing it is frequently necessary to make partial changes of formas, for example, in printing railway-tickets, transfers, labels, and the like, where the body of the form remains the same and the completed articles difier from each other only in the matter of containing different dates, The ordinary porate the same in the body of the form where they are to appear and then to print directly from the type, stopping the press, lifting the form, and changing the lines required, or to make as many separate plates of the whole form as there are to be changes and substitute one plate for another when a change is required.

The object of my invention is-to provide effective, simple, and economical mechanism for accomplishing the purpose stated without stopping the press; and to this end my invention consists in the features of construction and the combination or arrangement of parts hereinafter described and Y claimed, reference being made to the accompanying drawings, in which- Figure 1 is an end view illustrative of the relation between the impression-cylinder and the different printing-cylinders. Fig. 2 is an edge view of the impression-cylinder and one of the spindles operated thereby and containinga removable printingsleeve. Fig. 3 is a perspective view of one of the spindles with the detachable printingcylinder. removed. Fig. 4.- is an end'view of the same, the two parts being shown in locked position.

In carrying out my invention I employ an ordinary impression-cylinder 1, a roll 2 of the web of paper to be printed, a cutter 3, and a main or primary printing-cylinder designed to carry the blank-spaced form and to cooperate with the impression-cylinder to print a yondthe periphery of said cylinder.

blankspaced form-that is to say, a ticket, label, transfer, or like object-in such manner as to leaveblank spaces thereon at certain predetermined points to be subsequently supplied with the required printed matter to complete the same; The impression-cylinder 1 is provided with a gear-wheel rhich meshes with a pinion 6 on a spindle 7 parallel with the shaft on which the impressioncylinder is mounted and located slightly be The spindle? is provided with a cylindrical head 8, having an annular shoulder 0 thereon'adjacent to its inner end; The said head 8 is also provided with a groove 10, which is adapted to bereceived by a feather or spline 11 in the printingsleeve 12, having one or more plates 13 screwed or otherwise'secured to its outer surface and containing the matter to beprinted in the blank spaces left in the ticket or other form. The said sleeve 12 fits snugly upon the head 8 of the spindle and is locked in place thereon by means of a washer 14, which fits over the extended threaded end of the spindle 7 and engages the outer edge of said sleeve. The washer 1i is itself held in place by means of a split washer 15, which also embraces the end of said spindle and is forced inwardly and locked by means of nut 16.

In the foregoing description I have referred to but one spindle 7 and the parts cooperating therewith to provide the secondary printing mechanism, which prints in the aforesaid blank spaces in the form printed by the main or primary printing cylinder or mechanism. It will be obvious, however, that I may use a plurality of said spindles containing printing cylinders or sleeves having different matter thereon for the purpose of printing in the different blank spaces left in the ticket, label,

. or the like by the blank-spaced form of the main or primary printing cylinder or mechanism.

Suitable inking devices will of course be provided for the printing cylinders or mechanisms; but it is not considered necessary to describe the same.

Constructed as above. described it will be observed that if it be desired at any time to change the matter which is to be printed in the blank spaces on the form all that it is necessary to do is to loosen the 'nut 16 on the end of the spindle '7, remove the split washer and the main washer l4, and then slip the sleeve 12 from its seat on the head 8. To apply another cylinder containing different form-matter-as, for example, the date of the transfer or other ticket or the destination to which the ticket is to be issued--it is simply necessary to place a new sleeve 12 on the head 8 so that the spline or feather 11 will fit within the spline way or groove 10, insert the washer 14 over the end of the nut 16, apply the split washer 15, and tighten said nut 16. WVhen applied in this manner, the sleeve is held securely in place on the spindle, its proper registration with the blank spaces in the form printed by the cylinder 4 being obtained by locating the feather or spline 11 in the printing-sleeve12 at such position that when it is engaged by the groove 10 the spaced-apart forms or printing-plates 13 on the sleeve 12 will come directly opposite the blank spaces in the main form. 7

It will be understood that the idea of my invention is to avoid the delay incident to changing the plates on an ordinary rotary printing-machine for each change of form,

the lost time being that which is necessary to screw or clamp the plate in position on its cylinder and to adjust the same for register after it is on. It is frequently necessary to build up low and defective plates, and this is usually accomplished by pasting overlays on the impression-cylinder, which overlays of course are not only useless on the next change of form, but require scraping off and renewing to suit the next change. I paste them to the back of the plate before it'is screwed onto its sleeve, thus insuring its permanency and obtaining a material saving in the operation of making ready the form, as the underlay being between the plate and sleeve cannot be displaced. This is material and important and is a great time-saving factor in changes of small editions, which require a complete stoppage of an expensive machine for a very considerable part of the time and verymaterially reduces the production. I propose to have in stock a quantity of printing cylinders or sleeves which have plates thereon containing different form-matter to be printed in the blank spacesin the main form already madeready and imposed to register without adjustment, and when it is desired to change all that is necessary to be done is to substitute one sleeve foranother, the removal of the old sleeve and the application of the new one being effected in the manner heretofore set forth.

It will be seen thatin the construction'and combination described for first printing a form with blank spaces and subsequently printing any desired matter in said blank spaces the provision of the cylindrical heads and sleeves with interlocking grooves and splines or feathers arranged in the manner set forth is advantageous, desirable, and important in that by merely slipping the sleeves on the cylindrical heads and causing the grooves and splines or feathers to interlock the sleeves are not only forced to turn with the cylindrical heads, but the grooves and splines or feathers constitute registering deviceswhereby thespaced-apartprinting-forms on the sleeves without further attention or manipulation are caused to accurately register with the blank spaces of the form on the main or primary printing-cylinder, as hereinbefore explained. Although I have described and shown the spline or feather in the sleeve and the groove on the cylindrical head, they may be reversed without altering the function of these parts.

Having now described my invention, what I claim as new, and desire to secure b y Letters Patent, is

1. In a printing-press, the combination with an impression-cyli-nder, and amain printingcylinder designed to print a form containing blank spaces to be subsequently supplied with printed matter, of a spindle having a cylindrical head provided with a register-groove, a cylindrical printing-sleeve detachably mounted on said head and provided interiorly with a register-spline and exteriorly with a spacedapart printing-plate for printingin the afore-' said blank spaces, the groove and spline being arranged to cause registration of the spaced-apart printing-plates on the sleeve with the said blank spaces of the main printing-cylinder as the sleeve is placed upon the cylindrical head, substantially as described.

2. In a printing-press, the combination with an impression-cylinder, and a main printingcylinder designed to printa form containing blank spaces, of a spindle having a cylin= drical head geared with the impression-cyL inder and constructed with a register-groove, a cylindrical printing-sleeve lengthwise removable from the cylindrical head and provided interiorly with a registenspline and exteriorly with spaced-apart printing-plates to register with the aforesaid blank spaces to print the required matter therein, said groove and spline interlocking and arranged to cause registration of the said spaced-apartprinting plates with said blank spaces and devices for detachably holding the printing-sleeve on the cylindrical head, substantially as described.

8. In a prin tin g-press, the combination with an impression-cylinder, and a main printingcylinder designed to print a form containing blank spaces to be subsequently printed in, of a head having a pinion and a registergrooveand a central screw-threaded projection at one end, a cylindrical printing-sleeve lengthwise removable from the head andhaving an interior spline and exterior spacedapart printingplates registering with the aforesaid blank spaces, a washer arranged on IiO the screw-threaded extension and overleppin g one end portion of said sleeve, and a. nut for holding the washer in place, the interlocking groove and spline being arranged to register the spaced-apart printing of the sleeve-plates with the blank spaces of the main printingeyiinder, substantially as described.
