@F WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE PRINTING APPARATUS Application filed December 22, 1930. Serial No. 503,3?2.

Copending applications of mine show, describe and claim'a method of printing, wherein a flexible galley is employed-in which line printing members are mounted in one or more columns, this galley being adapted to be stored flat, and, for use, wrapped about the rotary drum of a printing machine. The present invention is concerned with means for applying such flexible galley to the drum' and for holding it tightly thereon in use.

To the. above ends, 1 form the galley near one or both ends with means to interlock with the drum in such manner as to frictionally retain that end of the galley in place while the galley is being wrapped around the drum. My invention also provides effective means for engaging the opposite end of. the galley and drawing it in an arcuate direction to tightly seat the galley on the drum My invention is illustrated in the drawings hereof, and is hereinafter more fully described, and the ssential novel features are summarized in the claims.

in the drawings, Fig. 1 is a verticalsection through a rotary printing machine equipped with my flexible galley and embodying the present invention; Fig. 2 is a vertical section through the printing machine, illustrating the galley in the process of being mounted on the drum; Fig. 3 is a longitudinal or axial section through the printing machine; Fig.- 4 is a plan of mymultiple-column galley, removed and flattened; Figs. 5, 6 and 7 are details in cross section through the galley in planes indicated by the correspondingly numbered lines on Fig. 4.

As illustrated in Figs. 1, 2 and 3, 10 indicates a pair of parallel end; plates of the frame of the printing machine. in this 9 frame is mounted a drive shaft 11 rigidly carrying a pair of skeleton disks 12'and 13 on which is mounted a segment 15 having a cylindrical exterior adapted for supporting the alley. p

The segment .15 may be held on theskeleton drum in any suitable manner. I have shown however, a sleeve 14 concentric of the shaft and mounted on hubs on the

end members

12 and 13 of the drum, and I have shown the segment provided with a suitable. hook 16 adapted to embrace this sleeve and be locked thereto as by a set screw 1'4, Fig. 1.

The flexible galley, designated 20, is adapted to be wrapped around the segment 15' and held thereon by means hereinafter described. This galley holds suitable line printing mem-' bers, as for instance the line slugs 30. having notches 31 at their ends enabling them to be held by suitable slats 21 on the alley.

When the galley carrying the line printing members is mounted on the segment, as illustrated in Fig; '1, the printing face of the printing members may coact with a platen 40 mounted on a shaft 41' carried by the end plates 10 to enable printing in the usual manner. In printing, any suitable means may be employed forv inking the type faces. ll have illustrated in Fig. 1, an inked ribbon 45 mounted on spools dficarried within the drum, this ribbon intermediately overlying the faces of the printing members. I intend being held slidably on the base plate, as by tongues 23, cut out of the base plate and turned upwardly and passed through slots in the strips and slats. The construction in this particular may be in accordance with copending application No. 445,501 filed April 18th, 1930, by myself and Peter M. Colquhoun. The purpose of mounting the slats and filler strips slidably is to enable the whole construction to ilex readily, so that the galley may be loaded when fiat and stored in that condition and thereafter bent with its form about the printing segment.

The line printing members which are held in place by projecting beneath the overhang-' ing galley slats 21 may be low height solid line slugs grooved at their ends in accordance with a copending application of mine Serial No. 503,87 3 filed concurrently here- I with, or they may be composite printing members made in accordance with my copending application No. 445,499 filed April 18th, 1930.

" The In any case, a form is made up of one or more columns of suitable line printing members which rest on the base of the galley and are held at their ends by the slats 21, the column being retained in compacted position by a suitable follower. I have shown for instance,

a follower 35 (Fig. 4) having tongues engaging opposite sides of the slats 21, this follower being claimed in application No. 445,501 heretofore mentione As the loaded flexible galley necessarily has considerable weight and requires some force for its flexing, it is important, in mounting it on the drum, that the end first applied to the drum be eifectively retained other than by a manual pull on the galley while the same is being wrapped about the drum, otherwise it is diificult for one person to apply the galley. To enable this engagement of the end of the galley.withthe drum, I provide a bar 50 secured across the end of the back plate of the galley and then turning across the end of the plate at right angles at 51 and then projectmg beneath the plate a short distance at 52. I secure this bar to the back plate by rivets 53 which have cylindrical heads extending a material distance beneath the back plate,see particularly Fig. 7 To cooperate with such construction, I make a groove 18 in one end of the segment 15 to receive the hooking flange 52 and I make cylindrical recesses 19 in the face of the segment near the end to receive the rivet heads 53. When the galley is .to be placed on the segment, the latter is preferably temporarily locked in about the positions shownin Fig. 2. alley is then held in a more or less uprig t position, and the hook 52 brought into the slot 18. In this movement, the rivet heads 53 first rest on the segment surface 7 beyond the recesses 19, but as the book 52 reaches its final position, the rivet heads 53 register with the recesses 19 and may be pushed into them. The wall of the recess nearest the segment end, by engagement with the rivet heads, efiectively prevents that end of thegalley being disengaged from the segment while .the galley is being wrapped around the segment, and until the other end of the galley has been locked in place.

It will be notice'dfrom Figs. 1 and 2 that the end ofthe segment having the notch 18, for receiving the galley hook 52, has an inner portion 48 continuing arcuately beyond that 55 .notch. This projecting portion makes a convenient guide in mounting the galley. I When the segment'is in the position shown in Fig.

" 2, the groove in the end' of the segment is not conveniently visible, but this is unim- 6Q. portant as the operator can simply shove the end of the galley inwardly in a general radial direction beneath the end ofthe segmentuntil it abuts the guiding projection 48, then a slight upward pull on' the galley causes .the

hook 52 to come into therecess, after which the projections are ressed into their recesses as already described Itis convenient to use identical bars 50 on the opposite ends of the galley, so that the galley may be mounted either end foremost, as desired. 'To look the free end of the galley, I provide means within the printin drum to engage the hook 52 at the free en and pull the same in an arcuate direction to draw the galley tight on the segment and there hold it. Preferably the galley is somewhat longer than the developed length of the segment, so that the whole locking bar 50 at the free end lies beyond the free end 57 of the segment, as shown in Fig. 1.

The means for engaging, pulling and holding the free end of the galley is shown in Figs. 1, 2 and 3. As there shown, it comprises a hooked plate 60 secured to a pair of radial arms 61 rotatably mounted about the sleeve 14 of the drum. These arms are normally pulled away from the end 49 of the segment by tension springs 63 anchored at one end to portions 64 of the arms opposite the plate 60 and at theirother ends to tension pins 65 extending from-the sleeve 14. The springs 63 are quite strong and are adapted to move the plate 60 away from the end 49 of the segment with suflicient force to draw the engaged galley tightly about the segment 15 as shown in Fig. 1.

In view of the force of the springs 63 in moving the galley-engaging plate 60, I have provided camming mechanism for readily forcing the plate 60 toward the segment to enable its easy engagement with the galley, after which, the release of the plate enables the springs to set and hold the galley. The camming mechanism mentioned comprises an oscillating roller 7 O eccentrically mounted in the

skeleton members

12 and 13 of the drum, provided with a radial operated arm 71 and with a tortion spring 72 anchored to the roller and to the drum member 12.

The spring 72 normally retains the arm 71 and the roller in the idle position shown in Fig. 1. When however, it'is desired to release the segment which is on the drum, it is only necessary for the operator to grasp the rod '71 and turn it outwardly against the l action of the tortion spring 72 and thus cam the'lqplde 60 toward the segment, as illustrated in ig. 2.

With the segment held by any suitable means in the oblique position shown in Fig. 2, it is simple to snap the lower end of the galley onto the retaining device provided by the groove 18 and the recesses '19 and then bend the galley about the segmentas illustrated in Fig. 2, until the bar 50 on the free end of the galley lies over the end of the hookedplate 60 with the flange 52 on this bar 50 opposite the groove 67 of this hooked plate. Then the operator releases his holdon the rod 71, which he has been holding dur ing the placing of the segment, and the plate 60 swings away from the segment under the influence of the springs 63, so that the notch 67 receives the hook 52 as shown in Fig. 1. As the release of the hooked plate 60 is completed by the operator allowing the rod 71 to be swung into the drum, the force of the spring 63 pulls the galley arcuately and causes it to seat snugly on the segment 15 and there remain during the printing operation. To release the galley at anytime, it is only necessary to stop the printing machine with the segment approximately in the position shown in Fig. 2; for the operator then to grasp the rod 71 and swing it outwardly from the drum, thus camming the plate 60 into position to release the galley which, by its elasticity, tends to unwrap itself from the drum. Then, the operator having stripped the galley, with the exception of the originally anchored end, from the segment, a slight jerk on the galley will pull the rivet heads 53 out of 1tlhe recesses 19, thus entirely detaching the g It desirable to provide a cross member at one wend of the galley forming a stop at the top in the column or columns, against which the line printing members may be compacted by the 'follower 35. My hooked plate 50 of itself forms such stop at the top end of the columns, and, such plates being attached at each end of the galley, either end may constitute the top.

There must be" come sliding relation between the retaining slats 21 and the end plates 50 to enable flexing of the galley. This might be accomplished by having theslats simply abut the inner edges of the strips 50 and pull away from them when the galley is flexed; but to prevent any possibility of such free end of the slat bending up and impressing the paper during the printing, I bend the slats 21 toward the galley plate adjacent their ends and pass them slidably under the plates 50,

as illustrated in Fig.6. To allow aneasy bend of the slat where it passes from the higher elevation to the lower, I preferably cut notches in the plates 50 as illustrated in F ig. 4. t

t will be seen that with my means for temporarily locking the initial .end of the galley on the segment and the means'for engaging and drawing on thefinal end, I enable one operator with his two hands to very readily mount the galley even though the same is of considerable size and weight; and, with equal ease, remove it whenever desired. Furthermore, when the galley is in place, it is effectively held on the drum during the printing operation. When removed, the galley is simply flattened and may be stored in that condition for. future use at any time desired.

The printing form on the galley may be revised by separating it in any desired region (the follower sliding lengthwise in the galley) and any obsolete line members skewed and removed, or any new members inserted or added, as the case may be, in acing one or more recesses in its face adapted to receive the projections of the galley and means in addition to said projections for anchoring that end of the galley to the printing member.
