To all whom t may concern: l

Be 1t known thatI, OSCAR RonsiiN, a

citizen of the United States, residing atv New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in printing cylinders of that class in which the cylinder is a printing plate cast or otherwise produced in a tubular or cylindrical form. This form of printing cylindei has certain well-known advantages in the printing art. To .employ a lprinting cylinder in the form of a tubular plate, however, because of its shape, special forms of press construction must be employed, in order to support the plate in printing position in the machine, so that it can be removed and placed in position in the machine.

Itis the object of the present invention to produce an improved construction whereby such tubular plate may be so supported in printing position in the machine as to be readily and easily removed and placed in position, and in which the parts employed for supporting the plate are simple and With these and other objects in view, the invention consists in certain vnovel combinationsand parts which will be hereinafter fully described. A.

For a full understanding of the invention a description. of the same will be given in connection with the accompanying drawings, in which- Figure l is a vertical section, lpartly broken away, of two tubular printing plates with the supporting means in engagement ,withy the plates for supporting them in printing position; Fig. 2 is a similar view showing the plate freed from the supporting means and ready to be removed from the machine; Fig. 3 is a diagrammatic end elevation, 4partly in section, of one arrangement of the printing couples in a printing machine employing the improved construction for supporting tubular plates; Fig. 4

is a front view, partly in section, of one of the form members of -the printing couples shown inFig. 3; Fig. 5 is a vertical cross section taken on the line 5--5 of Fig. 1;

Fig. 6 is a vertical section, partly broken away, of a modified form .of support for the plates, showing the supporting means in engagement with thel plates; Fig.- 7 is a similar view showing the plate ready to be removed from the machine; Fig. 8 is a diagrammatic end elevation, partly in section, of a different arrangement of the printing couples from that shown in Fig. 3; Fig. 9 isa plan View, partly in section, of one of the printing couples shown in Fig. 8, and Fig. 10 is an end View, lpartly in section, taken on line 10-10, Fig. 6.

Referring now to the drawings, the in vention has been illustrated as embodied'in a rotary web perfecting printing machine, though the invention is adapted for use and may be used in other types'of printing machines. In such machines, as shown, usually a plurality of tubular plates .are employed in each printing couple, the plates being arranged end to end, but it will be understood that if desired one such tubular plate may oe employed, and that the invention is notto be limited to the use of any particular number of plates. In the machine illus-v trated` referrin first to Figs. 1 to 5, four such plates, which, furthermore are preferably completely circular, are employed with each couple, these plates being arranged end 'ing couples arranged in line, the cylinders of the couples being in the same horizontal iran srnriis PATENT orrion plane and each including form cylinders l f and 2 and impression cylinders 3 and 4, the form cylinders being inked in the usual manner from distributers 5 taking ink from fountains 6, through the usual train of distributing rolls 7. Each form member includes in the particular construction illus- -trated four tubular cast plates 8- which may be dimensioned as desired, either one page around, or two pages around, the plates being cast in molds suitably lconstructed to produce a completely circular plate. These `plates form the printing cylinders and are supported, preferably and for the sake of simplicity in construction and ease in removing plates from the machine and in p ositioning them in the machine, only at their ends,

l,So that when freed from the supporting means the plates may be readily removed from between such 'means' and may be quickly placed in position therebetween and clamped in position. The particular means for thus supporting the plates may be somewhat varied, but these .supporting means will include a pair of heads 9, 10 for each plate, these heads being mounted so as to have rotary engagement with the plates at the ends thereof, so that by moving one of the heads away from the other the plates may be freed and removed'sidewise from between the heads. The particular construction for effecting this may be varied, but in the preferred construction and as shown in Figs. 1 and 2, in which two plates are shown positioned end to end, one of the heads, as 9,

will, While having a rotary movement, be-

. 9 is provided with a projecting stud or stem 30, which enters the hollow sleeve 12 of the i other head 9, and is'gsuitably secured' thereto by a key and'slot construction 31, the two heads 9 thus rotatin together. The movable heads 10 and t e means for moving them are .identical in construction, and only one will be described. This head is mounted 'so as to have a rotary movement and at the same time a lateral movement relatively to the other head, so that it can be freed from `the plate. While the particular means for thus mounting the movable head may be va-` ried, in the particular construction illustrated in Figs. 1 and 2 this head is carried on a shaft 13 which takes bearing in sliding sleeve 14,'the shaft being rotated in any sultable manner, as by sliding gear 15. The sleeve 14 is supported in a main frame 18 and is given a sliding movement to move the head. The lateral movement of the sleeve 1l may be effected in any suitable mannen In the particular construction illustrated, the sleeve has secured thereon -av-rack 19, this rack being moved laterally by means ofav pinion 20 on a shaft 21 which is or may be rotated by the use of a wrench or other suitable tool.

In constructions embodying the invention in its preferred form, locking means are provided between'the heads and the plate, sov that the heads positively engage the plate and any slipping between the plate and heads during the rotation of the parts is ef fectually prevented. While these locking vtioned in the heads. While these means may be varied, as shown they include stops 25 formed on the plate at each of its ends between the groove 22 before referred to, against which take flanges 26 on the heads.

With the construction so far described,

the plates are freed at one end by the withdrawal of the movable head. In machines embodying the invention -in rits preferred' form, means will be provided for positively freeing the ends of the plates from the stationary heads. In machines embodyingtheinvention in its best form, furthermore, these means will be operated through suitable connections from the head-moving means, the connections being such that the movable head is first withdrawn from one end of the plate and then the plate is removed from the stationary head at its other end. While these means may be varied, in the particular construction illustrated there are provided a number of pusher rods 27 one for each of the plates. These rods and-operating connections are identicall in construction and only one of them will be described. Re

ferring'to Figs. 1 and 2, as illustrated these rods takebearings in the frames 11, 18, before referred to, being slidably mounted in these frames. Each of the rods'carries a suitable 'pushing member for pushing the plate off the head. The construction of this member may, of course, be varied, but as shown it is a pusherl block 28 fast on the rods and having a pushing face 29 arranged to contact with the edge of the plate. This pusher block and rod is operated in any suitable or desired manner, but as before stated, in the-preferred construction it will be operatedto remove the plate after the head 10. has been withdrawn therefrom. While the particular means for eecting this may, of course, be varied, as illustrated the sliding sleevelt, before referred to, is provided at one end with a hanger arm 32 which is in sliding engagement with the bar 27. Be-

yond the hanger arm on the bar is located a stop collar33, against which the hanger arm 32 takes. During the first portion of the movement of the rack by which the head l0 is removed from the plate, the hanger arm slides idly on the rod. The continuing movement of the rack causes the hanger arm to take against the stop collar 33` and to move the rod 27 and, through it, the pusher block 28, thus freeing the plate from the xed. head v If desired, to insure the head 10 remaining clear of the plate when the plate isl removed from the fixed-,head` -9 by the pusher bar, as before described, a suitable stop, as a stop pin 34, mounted inthe frame of 'the machine, may be provided, this pin taking against theedge of the plate when the lplate is in the position shown in Fig. 2, .this pin preventing the plate from coming into engagement with the movable head 10.

In Figs. 6 to 10, inclusive, is shown a modification of the construction-'which may'.

be employedif desired, particularly .Where there are to be but two plates arranged end to end, or a single plate. .Certain parts of the construction shown in these '.gures -are identical with those heretofore described in reference to Figs. 1 to 5, inclusive, and

need not again be described in detail, the

same reference numerals having been used te ,indicate simlla-r parts. In the construction shown, however, in these figures, the fixed heads 9, between two adjacent plates,-

are rotatably mounted by means of a slightly modified construction. As illusltrated, referring to Figs. 6.and 7, there is provided a support, as an arm 11'-, suitably secured to the main frame of the machine, this arm carrying studs 12 projecting from each side thereof, on which studs the heads 9 rotate. If desired, and as shown in Figs.

.6 and 7 the pusher heretofore described for `shown there is provided a bearing 17 suitably lmounted in the' frame, the bearing 17 having a spring-seated pin stop 16 mounted therein and taking into an opening 1n the sleeve 14, this stop being `withdrawn from' thesleeve-when the head Vis moved laterally to free the plate.

In Fig. 8 is illustrated another arrangement of the printing couples, which may be employed, if desired.. Inl the, construction here shown, the couples are arranged with -the form members 1, 2 arranged below form members 3, 4 andopposing each other, thisarrangement being partlcularly adapted for certain press purposes. The

form cylinders in y this arrangement are inked in the usual manner through dis-l tributers 5 taking ink from fountain 6' through the usual .train of distributing rolls Machines 'embodying the invention will include a support for receiving the plate after .it has been freed from the head. While this support may vary somewhat in lcharacter, in the particular construction shown this support will consist of a curved frame 35 which may extend the length of the plates, as shown in Figs. G and 7, this frame being suitably secured to 'the main side frame of they machine, this 'frame being located closely adjacent the plate, the plate dropping onto this frame when it has been released from the heads. If desired, this support'may consist of a number, as for instance, a pair, of short curved supports 36 carried by the rods 27, before referred to.y As shown in Figs. 1 and 2, these-short curved supports are located at or near each end of the plate and closely adjacent thereto, the plate dropping onto these supports after it has been freed from the heads. c

While the construction so far described has been with reference to two plates arranged end to end, the use of more than two plates arranged end to end is contemplated by the present invention, and one such arrangement, in which more than two plates arranged end to end is used is shown in the drawings. Referring t Fig. 4, there is illustrated an arrangement in which there l are four plates arranged end to end. In this construction, as in the construction previously described, there are provided. a Apair of heads for each of the plates. These heads, whenthis arrangement is used, mayy be mounted in either of the ways heretofore described, they being mounted inthe particular construction shown, in the manner described in reference to. the construction shown in Figs. 1 to 5. Where, as in the arrangement shown, there are four plates arranged end-to end,- means will be provided whereby the middle plates may be removed from between the heads injorde'r to take them from the machine, or to reposition them therein. -While these means f may vary somewhat in character, in the particularA .construction illustrated means will be provided whereby the heads between the inner ends offtwo outside plates and the plates adjant', thereto may. be given a bodily movement sidewise. In the particularconstruction illustrated, there is provided a bearing frame 37, which may be stationary, v located between the two inside plates A38, 39, and two movable bearing frames 40, 41 located between the outside plates 42, 43 and the plates adjacent thereto. These bearing frames 37, 40, 41 carry supporting heads, and the outer ends of the outside plates 42,'43 engage ande-are supported by laterally movable heads 44, 45 which are removed from the plates inthe same manner as before described. The laterally movable bearing frames .40, 41may be moved in any suitable manner, as through' a screw construction 46 on rods 47, operated in any suitable manner, as by a hand tool.

- movable heads 44, are `first moved lat` erally, :freeing the outside ends of the two this way the inner plates may be freed from their supporting heads on the frames 40, 41, the heads 0n the movable frames being withdrawn from the plates and the plates pushed oti the ,heads on frame 37. y

With the construction described, a very simple and eflicient means is provided for securing the tubular plates in the machines, all unnecessary shafting for supporting the plates having been eliminated, and the mechanism for freeing the plates being eX- ceedingly simple and easy to get at. p
