This inventionrelates'to platens forprintingand addressing machines andfithas for its object generally to provide-a novel and simple sectional platen I for repetition print- T ing of all or; a certain part ofa printing form, or for alternative printing of parts' of the form.

The invention is. applicable, for example,

to, an addressing machine for making printing impressions from printing devices which are run through the machinerone at a time. A simple embodiment of these printing devices comprises a formfor printing ainame and a city and state address in two lines one above the other. Many of these printing devices are provided with forms for street addresses and for a variety of other information but the simple form willbbe" sufficient to illustrate a useof the invention It may be desired to print only the name,-, or only the address, of all of such simpleprintk ing devices, or itlmay be desired toprint the namei'and the ,address endlto end on the same line for listing or other purposes. I have found that-this can beeasily accom plished and produce entirely satisfactory; printing impressions by providing :asectional platen which is adaptedto .have one or the other section or both sections set for set for alternative printings vide novelfand. simple shifting means for.

causing the platen sections to operate auto-n of a printing form. x

matically in successionjupon different parts And a further object ofgthe i li longitudinally. movable in the platenhead to providenoveland simplemeans. for de; tachably securing the cushion plates of the. platen to the platen blocks. x f

The invention can be embodied witha reciprocating platen or Stamper arm. as shown for example in Patent No. 1,681,525, patented August 21, 1928:; or'it can befembodi'ed with a spring or'snapping platen and with a reciprocating or-fixed. platen or stamp'er" arm as disclosed in the application ofHenry -E. Hubbard, Serial No. 341,935 filed 'Febru ary 23, 1929, but I have chosen to illustrate; itjvith a fixed platen or; stamper. arm as a.

A Fig. '5 isv a sectionalview on the line 5-5 to ofFigfi. j 1 1 ,Figs. 6,- 7 and 8 .are end views, showing different positions of'the platen sections. lieferring to the drawings 9 isa fixed platenorstamper arm of an addressing mas chine in which printing devices are fed one at a time. to printing-position, but so far. as the present invention is concernedit might "justas well be a reciprocating arm. A supportforthe platenwhich is shown-in the form of a rocker 10is pivotally mounted at 11 on'the platen arm' and is adaptedto be controlled by means 112 connected with selec-- tor mechanismon themachinezwhich causes the platen to operateor not lto operate in. accordance with lwell' understood 1 practice. The platen comprises a skeleton head .13:

fwhich is secured onthe support by a.=holding screw bolt .14; and I .is maintained in proper position by adjusting screws .15. There are twoplaten blocks 16,17 movably arranged sideby. side on-the platenihead and they are provided at their ends with cam surfaces 16, These blocks are yieldinglyheld in thehead by springs 18 which are attached on the blocks. A shaft =19 is rotatably and and-it has tWogrooves-QO, 20. A spring:

engage'either groove to retain the shaft in adjusted position. Gams22, 22 are fastened v.onthe shaft 19 to engage the cam surfaces 16,,17f= and ashifter 23 is rigid 011 the. shaft and may bem'ade integral with the M1 22, A.

as shown, and carries tworrollers. 24,-:24. z A tripper 25ris pivoted atf25f on platen arm'.\ 9 and it carries. a. pin. 26 which projects. through. an :arcuate slot in the arm and carries a"- washer. 28 which overlaps the slot.

s5- at their ends to pins on the head andto pins A spring 29 is attached at oneendto the I pin 26and at its other end to a pin 29' on platen arm 9 at the right of pin 26, Fig. 1.

A spring 30 is attached to the pin 26 and to a pin 30 on the platen arm 9 at the left of pin 26, Fig. 1. The tripper hangs freely from its pivot 25 but is heldnormallyin centered position by the springs 29, 3O andit is provided at the bottom with a foot 31 and a recess 32. By'adjusting the shaft longs tudinally the shifter will be moved into operative relation "with the tripper for alternative printing or out of operativerelar tionwith the tripper for repetition printing.

Each platen block 16, 17 is provided with a.

longitudinal. 1'ecess'33 to receive a removable plate 34 which has a cushion facing 85. The

plates are detachable so that they can be easily replaced whenever required. Spr ngpressed. retainers 36 carried by the platen blocks 16, 17 are provided'withheadsfl'f' to engage keyhole slots 38 in the plates 34.

i The heads87 are adapted to enter the keyhole slots when the plates are arranged in the longitudinal recesses 33 in 1 the platen blocks. The heads and thej walls ofthe keyhole slots are beveled to elfectinterlocking engagement of the heads with the plates when the. plates are moved length'wiserelative to the platen blocks'so that the plates will be held snugly in place, on the blocks.

The plates are provided with handles 34 tov facilitate attachment and detachment with the blocks,

partly formed in platen-block 17 to look'the shifter inposition-when the shaft and shifter are-adjusted for causing eitl er or both of;

the platens to operate.

Assuming that the invention is embodied? in an addressing machine and'a pluralityof. printing devices having two line printing forms are feedingthrough the machine, and it is desired to print only acertainli'ne of" the form, ,the shaft -19 wi1l be adjusted longitudinally f. to move thei shifter out ofoperative relation to the tripper, and will also be adjusted rotatably to position the platen section for making a printing im pression from the particular; line form.

Then the machinewill operate inthe usual manner for printing only the: 011611118101 which the platen section is set from each of the printing devices feeding through the machine; and this printing operation may Y be controlled by selector mechanism as com monly embodied n addressing and printing machines. If'it is desired to print from the other line form-of the printing devices the shaft will beturned to cause the cams to "set'the other platen sectionin operative position, Fig. 7.- If it is desired to print The shifter has an arm 39,.which carries a detent LO-adapted to engage a liecess 41 in the end of platen block 16,21. recess" 42 in the end of platen block 17, or a recess 43 partly formed in platen block 16 and from both line formsof the printing devices the cams willbe adjusted to hold both platen .sections in operative position, Fig. 8. The v detent is engaged with the recess 11, the

recess 42 orthe recess 43 to hold the shifter in. adjusted position, as indicated in Figs. 6,-8. If-it is desired toprint the two line formsendto end on the same line on the sheet, two printingfloperations will be necessary and the printing devices or the sheet or. both must. be shifted; accordingly, but this forms no partfof the present invention.

However it is necessary to provide forautonatically shifting the printing sections alternatelyintoand out of printing position .as' indicated, for example, in Figs. 6 and 7, and the shaft 19 is adjusted longitudinally to position the shifter fOT'OPBI'BilVG engage ment withIthe tripper, Fig. 2. Then the shaft issetrotatively to adjust the cams forcausing one or the other platen section toprint first, as shown for example in Fig. 6. i This adjustment; will be convenlently made with the platen in lowered position. When the platen rises the shifter will engage and jbe shifted bymthe tripper to its other "position", as indicated in Fig. 7 with the other printing section in operative position. On the printing "stroke of the platen this other platen section will make the printingimpression. On the return stroke of theplaten the shifter will again engage and beshifted by the tripper toits first positionFig.- 6. 7 hen the shifter is in the position shown in I Fig. 6 and the platen rises the'roller 24 will engage the inclined portion'pf the shoe 31-andv travel thereon into the recess 82. f This causes the shifter .to swing tothef'position'shown in Fig. 7.

When the platen risesagain with the shifter positioned as shown 'in Fig. 7 the roller 24 V will engage. the recess in the tripper and swing the shifter to the position shown in Fig. 6. The tripp'erf swingson its pivot to .permit' and to effect these shifting movements of the shifter'b'ut, when the shifter moves out of contact with the tripper the latter is immediately centerediby the springs 29,30 for thenext operationl It will be jreadily understoodi that in this operation j as-well as in addressing and printing machlnes of many lands, and l reserve the right to make all such adaptations and to {make any changes in the invention that may be-necess'ary or desirable within the scope of the following claims.
