In fthe form ,of our ifnventiomshoWn by Wa-y fofiilustrntiojn, 1 'is any suitable form of, plate cylinder .upon iwhicli is secured the printing `plete 2 :by the outer clips .3, i3 four such clips being shown in Fig. 1.. Cooperating ;:Wit'h these outer clips 3, 3 =are the inner clips 4, 4,;one being'shown in F rigs. 3 land 4. lt isv understood-.that there are four .ozf such -inner eli-ps f1 for -eeeh printing plate, making eight clips in all vtor .each printing plate.

Mounted on the aperipheryof the plate cylinder '1, `are `a pluralityof :longitudinally ex- .tending grooves 5 within cach Aotl .which slide nn outer and an inner clip 3 :ind 4. and also a Clip rod G, This .clip frod 6 is formed 1of two parts 7 Yand 8. The .end of the portion 7 is provided With female. :threads 9 to cooperate with the male threads 10 on the portionrS. The .exterior of the portion 7 of the vclip rod 6 is provided with serenthreads 11 on which are mounted the stops 12 end 13. These `stops are :preferably in the form of nuts and are held. in their zxd justed position by the respective Set screws 14, 14.

The portion S of thc clip rod 6 is also provided -with n spline 15 to receive the end of the screw 16 which is threaded in ythe part 1T of the plate c vlinder I. The yend of the portion 8 of the clip rod is provided with infile threads 18 to cooperate with the stops 19 and 20. which nre preferably in the forni of nuts. A check mit 2l may also he employed.

The threads 10 on the inner portion 8 of the clip rod 6 are one-half the pitch of the threads 11 on the exterior ot the portion 7 of the clip rod. The interior of the vouter clips f3 :1re provided with female .screwthrezids 22 lto cooperate with the male threads 11 on the portion 7. The inner clip 4 has a smooth;bore. 23 and rests loosely vupon the screw-threads 118- on the portion 8 of the clip rod 6.

.. .The portion 7 ofthe clip rod is provided with a shoulder 24, `the end being prefer.-

' the parts that the space 34 between the stop orlock nut 19 andthe inner clip 4 will preably formed'squarefor non-circular, to be engaged by a spanner, -monkeytwrench,,or other tool. Near the squared end 25, we secure a collar 26 by a set screw 27-.to engage with the coil spring 28 in the unlocked position lof -v he 'clipq'od-,as -will be more fully hereinafter4lescribed.

'i The check nut 12 is secured on the clip -rod 6 for afpap'er or other printed productof, for.- example, "7 columns, andthe checknut 13' is'seeured ontheclip rod 6 vfor adifferent number of columns, orf example, 6- columns. Thelock-up.- plate' 29,5 supported -by-...the guidef studs 30, 30 is provided .with a recess 31 to--reeive the end"of='the"fclip' rod 6,-and the coil` spring 128 whichl lbears againstlthe shoulder 24 Lonv ithe clip rod` 6 and' one of the en'd'plates 'iSO'Nvhich plates are-secured to the' 'face of the lock-up plate 29 .bygthe lscrews'31f, 312, vtherebeingf,v intheiform showrna separateend plate forneach clip rod 6.- i.' 1; l "ifAs'suming thatvthe plate cylinderl is to print from aniinner\.plate.32, as Well'as 'from an outer printing plate 2, and that the newspaper, orotherprinted product, is, for example, to have seven c'olumns,ourv lock-up will then be in the position shown in Fig. 3, in which the inner plate 32 cooperates with v.the-fixed center clip 33' and with lthe movable inner clip 4 and the outer clip 3. When an outer plate 2is vused we preferably adjust t-he-check-'nut or stop -19 on the niember 8 to leave a space 34 between the stop and the inner clip 4. v`

XVe employ -the usual eccentric lock-up formed of a shaft 35 mounted in the lockup plate 29, the eccentric end 36 of the shaft 35 being mounted in a shoe 37,.mounted in a recess 38 in the end 39 of the hub of the plate cylinder 1.l By placing the key .40 in the seat-41, formed for its reception in the end of the shaft 35, the lock-up plate 29 is caused to move to or from the plate cylinder to actuate the different clip rods 6, 6 to lock or unlock the dilerent printing plates carried by the plate cylinder. l Vhen the key is operated, in the manner' just described, to lock the outer printing plate 2 andthe inner plate 32 to print a newspaper, for example, having seven columns, the parts will be in the position shown in Fig. 3,' where the spring 28 is compressed between'the end plate 30 and the shoulder 24 on the clip rod 6, thereby lirmly but yieldingly pressing the clip rod 6 to the right, causing the threads 1l on the` portion 7 cooperating with the threads 22 on the outer clip 3 to force the outer clip to move to the right, and transmit. the locking spring pressure of the spring 28 througn the outer clip 3, outer plate 2,'inner clip 4, inner printing plate 32 to the fixed center clip 33. A

It will `be noted that in this position of vent the stop or nut 19 transmitting any pressure to the inner clip 4, thereby permitting the entire strain of the locking springr 28=to"=beitransmitted through the-outer and innerwprinting plates 2and 32 to the center fixed-clip 33.

To release the printing plates2 and 32 the eccentric lock-up is-operated by the key 40 in the opposite direction to permit the lockup .platef29, .vvithitsjend `plates 30, -to move to lthe left of the position shown inFig. f3 andfinto :theposition shown in Fig. 5,:which is the.unlcked position-' This permtsfthe outerlfandf innerxprinting plates to be removedand replaced 4 with other -plates to printla newspaper, or other printed product, of' the same width of.sheetyherereferred to, for purposes of S'description, as seven columns.

In unlocking the eccentric lock-up and with. more vparticular reference to Fig. 5, it will be seen that whenthe spring 28 is released-it will have va tendency to force the end plate 30 and the lock-up plate 29, on `which it-is mounted, so -ar to the left in Fig. 5, that the surface on the lock-up plate 29 would engage with the surface 46 on the shoulder 24, were it not prevented from doing so. To prevent these two surfaces 45a1id 46 from contacting with each other, we mount the collar 26 on the clip rod 6, which collar passes freely in the opening 47v in the end plate 30. The coil spring 28 is suiliciently large that itv not only engages with the interior surface 48 of the end plate 30', but also with the inner surface of the collar 26, when the parts are unlocked as shown in Fig. 5. This collar 26, is adjusted by the set screw 27 to a position ou the cli'p rod 6 so that it will engage the spring 28 before. the spring can bring the surface 45 on the lock-up plate 29 into contact with the surface 46 on the shoulder 24. leaving a space or clearance 50 as shown in Fig. 5.

This is particularly desirable, for if these two surfaces 45 and 46 contacted with each other under the action of the spring 28, so 1 much friction would he developed at this point that it would be difficult for a hand tool to operate the clip rod 6.

lVith the parts in their unlocked position (Fig. 5), and it is desired to print a nevs4 paper, or other printed product, of a less number of columns, as for example, six columns, all that is necessary is for the operator to rotate or screw the clip rod 6 by auf;v

suitable hand tool applied to the square end Lita-'583035' t'lireads 11, cooperating with the tha'ds' 22 on "the interior of the' clip, screw-threads' 10, and 9 are cooperating 'with' each other, butA as their' pitch is' ha'lf that of the threadsv 11 and 22, the 'portionl 8pt the cl-i 'rod 6 is'm'oved to the right only half the(` p istance, the feather k16 in the spline 15 preventing' the. rotation-'oi the part sof the clipv rod.

In the' specification' and claims, Areference'has beeni made' to different number of columns or different column Widths, as well as to different number of'coluinns or width of sheetto be printed.' It is to be understood that these terms are' meant to, and do cover different lengths of stereotype plates regardless of the Width of sheet, or

the width of printed matter, or the num-A ber of columns. lt is vclear thatiyou can print' any number of columns With'th'e same length plate and with the same Width ot printed matter' and the same'V Width' o f sheet.- by varying the Widths of the columns. It is also possible to vary'the Width of the printed matter without varying the length of the stereotype plates or the Width of the. printed sheet. ln such case the Width of the margin would vary, as for example, by casting a blank margin on the end 'of .the stereotype plates. By arranging the printed matter and blank margin on the .stereotype castings` it would be possible to print on different widths of sheets without 'varying the length ot the plates. Again stereotype plates are not always cast with the columns transverse to the axis otthe printing cylinder'. They are often cast with the columns running parallel with the axis of the cylinder. In such cases the width of the printed matter would become the length of the columns', and a shorter or longer'column might necessitate a shorter or longer p'latc.V All V'these uses are, and are meant to be, `included iii lthe claims.

The' invention in vits broader 'aspects is not limited to the specific mechanisms shown and described but; departures may be made therefrom' tithiri the scope of the' acconr panying claimsWithout"departing from the: principles of the invention and without sacrificing its chief advantages.
