JOHN ARTHUR HAYES, OF MANCHESTER, ENGLAND.

PRHITING MACHINERY.

Amman m rm To all whom it may concern:

Be it known that 1, JOHN ARTHUR JEF- FERSON Hares, a subject of the King of Great Britain, residing at 21 Spring Gardens, Manchester, Lancashire, England, have invented new and useful Improvements in Printing Machinery, of which the following is a specification.

This invention relates to continuous rotary printing machines particularly of the class operating with fatty inks or colors and by means of printing rollers, upon paper, textile fabrics, floor coverings, metal sheets and the like.

According to the invention all those parts of the machine which, upon a change of color or ink or design being required, have, in the ordinary course, to be removed or cleaned, are mounted upon a frame or frames, which frame or frames is or are made detachable from the main frame-work of the printing machine, so. that when va from the machine change of color or design is to be made, the frame containing all the parts for feeding, impressing or otherwise deali I with such color or design may be detached laodily from the machine to be immediately replaced by another frame having its attached members more or less completely prepared for immediate work.

Accord' to the process of printing employed and the construction of the machine, other parts besides those carrying the ink may be fitted to the removable frame to be moved therewith.

The invention consists further in the provision of a carriage which is 'adapted to run upon .rails or otherwise up to the rinting machineand to receive the removab e frame or frames directly from. the machine and to carry them away for cleaning or other attention as desired; the said carri es also serve to supply fresh frames having the 'h operative parts readv prepared for printing.

In the case of a machine employing a number of printing rollers or sets of printing rollers, the removable frames may be arranged one above the other, and. in this case the carriage is advantageously constructed with several tiers or-platforms for receiving the severalsuperimposed removable frames, which can be transferred simultaneously to. the carriage orv vice versa.

To enable the invention. to be fully underspocificationof Letters Patent.

stood it will now be described by reference to the accompanying drawing, in which Figure l is a sectional side elevation ofa continuous rotary lithographic machine having the improvements applied thereto. Fig.

are a part sectional plan thereof. Fig. 3 is a section on the line 3-3, Fig. 1. Fig. 1- is a front, view of a suitable form of' carriage for receiving the removable frame or frames from the machine, and Fig. 5 is a side elevation thereof. Fig. 6 is an elevation of a continuous. rotary lithographic printing machine provided with a plurality of pressure rollers vertically superposed, and having the improvements applied thereto.

Beferrin first to Figs. 1, 2 and 3 a repre sents the frame of the continuous rotary lithographic machine which. is adapted for pmntuig in. two colors. 6, b are two. printmg ro erswhich act in conjunction with'a common im ression roller 0. Each of the printing rol ers b isv mounted upon the removabl'e frame (Z, that is to say, in bearings d, d secured to the said frame- 01. The lat,- ter is adapted to slide on undercut guides onto and removed from the frame a moggpon the main frame a so that it can be pas rame g carrying the color box it and distributing rollers It, together with. the usual accessories. The frameg can be horizontally slid on to, and removed from, the frame (2 and is locked in position by means of the andscrew i which passes. through the nut 2" out; bail or stirrup i pivoted on each side o the sliding frame (1. The inner end of the screw'i bears against a spring plug or buffer a? and when ti htened presses the innermost distributing rd ller against the periphery of the printing roller 6. It will, therefore, be seen that the frame y can be removed from the frame d by unscrewing the hand-screw z and turning down the bail on stirrup 71 Also, that the frame at can be removed from the main frame it either before or after the subsidiary frame 9 has been removed. jrep- 1 1 to say, a carriage com resents the material to be printed which passes from the roll is around the impression roller 0 and between the said impression roller and the two printing rollers b, b whence it is conveyed awayover the guiderollerl and stored upon a'drum or in any other convenient manner.

In the construction of printing machine described above, power is impartedfrom any convenient source to upon which are mounted the two toothed wheels n, n earing respectively with two toothed whee s 0', 0,,upon the shaft 0' of the iinpressioii roller 0. The toothed wheels 0, 0 also gear on either side with toothed wheels 7), 2 upon each end of' the two printing rollers b, b, the said wheels p arin with the train of wheels h on t e r0 With this construction of machine it will be'obvious that should it be necessary to effect a change of color or ink or of the design to be printed or of the size of the printingroller, it is merely necessary to remove the frame 9 or the frame d together with the frame 9 and to replace the said frame or frames with a substitute or substitutes containing theyrequired color or ink or design upon the printing roller. To facilitate the manipulation of the frames in this way use is advantageously made of a carriage such as that illustrated in Figs. 4 and 5, that is rising at body 9 the as shown at q, to

top of which is shape receive the frame removed from the printing machine, either alone or together with the'frame g. When the frame 9 is to be removed, leaving the frame (1 in the printing machine, a. detachable top '1', shown in broken lines in Fig. 5, is )laced upon the top of the body. The bo y is. mounted upon the wheels 8, s preferably arranged to run upon rails.

In the machine illustrated in Fig. 6, two

pairs of printing rollers k, k and l, l are arranged vertically one above the other, the two rollers of each pair bearing against opposite sides of the upper and lower im ression rollers m, n respectively, and 0', 0 and 7), .p' are the inking or color accessories. The printing rollers k, k and l, l are mounted upon movable frames l, l slidin in the main frame of the machine, the said movable frames being arranged in pairs vertically one'above the other and being constructed as hereinbefore described with reference to Figs. 1, 2, 3, 4 and 5. The inking or color accessories 0', '0' and 'p', p are mounted upon the movable frameso, 0 and p 79 respectively, the said frames being adapted to slide in guides upon the frames Z'-, l carrying the prmting rollers k, k'- and Z, l. q is the roll of material to be printed, the said material q passing first between the left hand printing roller is and the upper impression. roller m and thence passing the main shaft m.

lers h d, when the said frame. is.

down" between the left hand printing roller 1 and lower impression roller n around the latter of -Wh1Ch it passes and emerges between the said roller and the right hand lower printing roller I after which it passes between the upper impression roller m and the right hand printing roller k and is conveyed away over the guide pulley r to a drum or other convenient means ofistors, s are rollers the peripheries of which are furnished witha substance such as powdered French chalk with which the surface of the material 3 to be' printed makes contact between eac impress on, the object I each impression before the next impression is effected. a p f It is obvious that with a'machine of the above described construction, both the inking or color accessories and the printingv rollers may be readily run off the main frame of the machine and removed with the aid of a carriage of the kind shown in Figs. 4 and 5, such carriage'being provided with a number of tiers or platforms correspond ing to thenumber of the superposed removable frames upon which the in ing or color accessories and the printing rollers are mounted.

Having now fully described and ascertaine'd my said invention and the manner in which it is to be performed, I declare that what I claim is 1. In a lithographic printing machine, the combination with a main frame having an impression cylinder mounted in fixed bearings thereon, the said main frame being provided with guide ways runnin longitudinally thereof and extending to the outer end of the machine, of a frame ads ted toengage and be moved in said gui 'e ways toward said impression roller and removable from the frame by moving said frame in said guide ways out of engagement therewith and free from the frame, a printing cylinder. mounted upon said sliding frame in position .to be brought into proper relation with the im ression roller, said printing roller frame eing provided with guide ways of a like character to those ofthe main frame and a further frame carrying inking devices adapted to be placed into engagmeinent with and moved toward the printin rollerand also movable outwardly along t e guide ways out ofthe printing roller frame, said printing roller frame being also provided with a bail and screw to secure the inking frame in operative position, substantially as described.

2. In a lithographic printing machine, the a combination with a main frame and an impression roller mounted thereon, of a se ries of independent frames each carrying a printing roller and each frame being inde- 80 beingto dry the said surface after series of frames each mounted on pendently movable on the main frame and I of a series of independent frames each movlndependently removable therefrom, and a I'ably mounted and adapted to slide in one of one of I said guide ways, a printing roller and a said printing roller frames,- and provided I dampm device mounted on each of said with inking devices each of said inking sliding frames and inking devices removably frames being movable on and removable secured to each of said sliding frames, substantially as described;
