PRINTING PLATE HOLDING MEANS Filed Sept. (5, 1929 2 Sheets-Sheet 2 mulation of extraneous matter, such as particles of Ehe type plate composition, ink, oil, and t-he like, adhering to the contact surfaces, not only preventing the ready inser- Cion and removal of ehe characters or plates, but preventing accurate registry in eolor printing, and it was to overco1ne the deliciencies of such devices and to provide a holding means adapted to hold a printing plat-e, a plurality of lines of individual type characcors or type strips, and comprising means for engaging tl1e edges or flanges o1 such pla es or printing characters, and adjustable to accommodate difi"erent sized prin ting element-s, slidablo keepers adapted to engage said printing characters to lock them in position and so designed as to prevent marring of either the contact surfaces of the characters or plates or the cont-act surfaces of the holder proper, the prineiple of the invention being applicable with equal facility 130 band sta1np or rocker arm 1narl; ers, and cylinder o1 flat bed presses, said holding means eliminating the usual chase and const-ituting a form when tho usual printing elements are operatively positioned, that I designed the holding 1neans forn1ing the subject matter of this invention In the utilization of n1y holding 1neans slight variations in for1n are, of oourse, necessary as applied to hand marl:ors, and cylinder or flat bed presses, but without departing fro1n the prineiple of the invention, and in the form illustrated in Figs. 1, 2, 3, 4: and 5, there is shown a band o1 rocker arm marker A; a slightly modili-ed 1iorn1 o1 marker B shown in Figs. 6 and 7, and whieh without the handle is equally applioable to cylinder presses, and fiat bed presses, when formed with a plane surfaee; and aslmilar form C, primarily for flat bed presses, Where the use of different sized printing characters is desirable, as shown in Figs. 8 and 9.

The band stamp or rooker arm 1narker A is forrned with a base or plate holdlng mombe1 1 curved i1om end to end as shown in Fig. 2 and formed With a series of spaced longitudinal slots 2 adjaeent each end, and a plurality of plate engaging T-shaped bars 3 adapted to extend transversely 01: men1ber 1 and in spaced parallelism with each other,

each of said bare being for1ned with a series.

of countersunk apertures 3 adapted to register with slots 2 and receive sorew holt 4-., the opposite surlace of plate 1 1nay be countersunk along each edge of the slot to accommodate nut 5 to hold the same agains turning While holt 4 is threaded therein er nut 5' may be formed with a T-head as shown in Fig. 5 for a siniilar purpose.

The bars 3 are adapted to engage the flanges 6 of a printing plate 7 having suitably formed thereon printing oharaeters 8 to maintain said printing element: -or plate in operative osition on holder 1, and are adjustable longitudinally with respect to said slots to accommodate printing plates or ele- 1nents of diflerent sizes and to properly position such elements with respeot 130 the holder 1, for printing 011 or marking coarse fab rics, wooden containers, corrugated paper, galvanized iron and bhe like. Each of the intermediate bars 3 is adapted to engage the flange of a printing plate 011 each side of the bar, as indicated at 9 and 1-0, respectively,

and it is obvious that a series o1 plates 7 of varying sizes may be suitably 1nounted on the holder 1 and when the bars are brought into engagement with the flanges 6 of said plates and secured in position by tightening holt-s o1 screws 4, the holder 1 Ehen oonstioutes in effect a form.

Suitably secured to the back 01 said holder 1 by welding or other suitable fastening means is a frame 11, in Ehe present instance, iern1inating at each end in upstanding spaced ears 12, in which are suitably mounted transversely extending handles 13 by means of Whieh the marker A is operated, as Will be understood without further description. However, for reasons hereinafter more. fully appearing, the fra1ne 11 may be detachably secured to the holder 1, if desired.

F r0n1 the above it is clear that said printing charaoters may be expeditiously rernoved loy loosening the bolts 4 and disengaging bars 3 fro1n the respective flanges of th-e printing plates o1 printing elements, as desired.

In I1igs. 6 and 7 there is shown another forrn of n1arker B in Whieh the face of holder 1a is formed with a plurality of parallelly extending longitudinal channels 141, the side Walls 0f eaeh of the channels being; grooved as at 15 to slidably reeeive cl1e flanges 6a of the printing plate 0r individual printing elements 7a for1ned with printing charaoters or indicia 8a, and it is evident that the printing characters 1nay be formed individually and assernbled in said channels or they rnay be formed on an integral platze or strip similarly 1nounted therein, in either case such plate or characters being locked in position loy keepers 16 for1ned with siniilar slidable flanges 6a, each of said keepers when brought into engage1nent With its respective printing element or strip adapted to loe locked in position by actuation of screw 17 extending through said keeper and into binding contaet with the roughened surface 18 of the longitudinally extending groove 19 formed in the bottom Wall of' channel 14, as

' Will be clear Without further discnssion.

Holder 1a 1nay be ourved similar to holder 1, as shown in Fig. 2, and provided adjacent eaeh end with brackets 20 seoured to 1ne1nber 1 similar to fra1ne 11, and said braokets are interconnected by handle 21 secured therein by bolts 22 or other suitable fastening ele- 1nents. The form B as above described is also adaptable, When minus brackets 20 and hangroovecl, is

c. lng mechanisms,

clle 21, to be mounted on a cylinder press, anal 01 conrse, may be provicled wi th additional channels 14 as desired when so appliecl. This type, when formed flat insteacl of likewise adaptable for flat bed presses and 1nay have its channel arrange- 1nent elightly molified to accorhmodate different sized printing elements as shown in Fig. 8, 110W to be clescribed.

The form illustrated in Fig, 8 and indicatecl by reference character O is substantiall v similar to form B except that its longitudinal eclges may be formecl with flanges 23 to be more reaclily securecl in osition 011 a Hat beel p1ess, the face of holder 1bis formecl with ehannels 14b and Wltll grooves 156 ancl longitudinal grooves' 19b having roughened bottom surfaces 18b, the printing elements 7b formecl with eharacters 86 and keepers 165 with locking screw 176 beingassemblecl and 1nountecl in saicl channels in the same manner as the similar elements above descriloecl in conneotion with form B. One of the channels 146 in form C is formecl wider than the other -1 channel ancl is entirely similar in all resp-ects except aclaptecl to accommoclate printing element- 01" elements 7b ancl pr1nt1ng oharacters 8?) of larger dimensions than the sin1ilar elements 0'f the other channel, ancl in orcler t0 securely locl saicl elements therein, the botton1 Wall is formecl With two grooVes 196 insteacl of one ancl the keeper 16b is provided With a corresponcling nunnber of locking screws 17b.

In view of the above, it is evident that the wiclth of the channels 145 may be variecl accercling to the partieular reqnirementswithout cleparting from the spirit of my invention.

From the foregoing it is apparent th'at I have clesi.gnecl a printing plate holding xneans, 1nore espeolally adaptecl to accommoclate printing plates or ele1nents comprising a s0licl metallic backing and a superimposed nulober 0r other resilient design bearing material seeured to one surface thereof, such as clescribecl ancl claimed in an application filed concurrently herewith and forrning an improvement on my prior Patent N0. 1,589665. Also, that the forme above described are similar, being only modifiecl in the way of provicling handles ancl to accom1noclate printing plates for difl'erent types of work, ancl fo1 ntilization in conneetion with different prlntfor cliflerent types of print ing such as band stamps 01 rooker arm markers, cylincler presses and fiat becl presses. Likewise, I have provicled printing plate holcling means, in sonne instances, obviating the necessity 0'f the chase ancl constitut-ing when operatively asse1nbled aprinting for1n, so designecl that the printing elements may be exneclitiously inserted and rernovecl fro1n' the hlclersancl without cleleterious effect 011 the coacting contact surfaces o1 holders ancl plagb es :by the atta'ehing 1 means, :aincl thronghout;l on g ang:l nonfinned nsage yet simple in constnuction, versatile in ;;use, vmanuia-cturable at 1a &ne gligible COSfi Qnfl' eflsloient for r;t he punposes intenclerl.
