To all whom it may concern .t

Be it known that lf, THOMAS J. BUCKLEY, a citizen of the United States, and a resident of New Brunswick, in the county of Middlesex and State of New Jersey, have I invented certain new and useful Improvements in Machines for Printing Tubes, of which the following is a specication.

The invention relates to machines for printing metal containers and other articles in cylindrical or tubular form, and its objects, among others, are toproduce a device of this character of simple, durable and effective construction and operation to provide for a higher eciency and a better `quality of work, and to provide for various adjustments of the parts to that end.

. The improvements reside in the construc. tion and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a side elevation of a machine embodying the improvements. Fig. 2 is an enlarged elevation of certain parts of the machine viewed from the opposite side to Fig. 1. Fig. 3 is a plan of some of the parts shown in Figs. 1 and 2.

The framework ofthe machine consists of twoparallel u right frames 41 and 2 spa-ced apart and having recesses 3 and t therein, in which are adjustably mounted sliding journal blocks 11 and 1 2'provided with adjusting screws 13 and 14,' and springs also mounted in the frames, for moving the same. ln these journal blocks vrotate the ends of the shafts on vwhicliy the 'bed-plate roller 20 and inking roller 21 (see dotted lines Fig. 1) are mounted. The ehafts on which other rotary, members ot the machine are mounted also have theirv journals in the said frames, lthe journal at one end being mounted in the frame on one l side and the journal at the other end being mounted in the opposite frame. 'llhis includes the pulley shaft 22, the cam Shaft 2B, the segment gear shaft 24: and the idler shaft 25.

lnk is supplied to suitable rollers 26,21 and 28 mounted in vertical slots in the supplemental upright frames 5, and the lowermost of these rollers, 28,.are in Contact with the large inking rolleror cylinder 21, which te Speciucation of Letterslatent.

reief figures adapted to print an impres-` sion on the tube 40, on themandrel 4:1, which is adapted to be rotated when in printing position by the shoe 31 on one end of the cylinder 2 0 which is preferably made of t5 rubber or other compressible material so as to revent slipping.

here are three mandrels Ztl, and each is a hollow tube with closed outery end'mounted lon a non-rotating post 4:2., and furnished 7u with ball bearin s 43 at its base and 44 at its outer end. he posts t2 are in turn eccentrically mounted on a disk Ylon the rotary head 4&6, and are adapted to be moved intermittently through yan arc of 12,0 dei5 grecs with the said head. The eccentric mounting of the posts. provides afli'mited adjustment of the mandrels totake up 'weer l and for other purposes.

rllhe ste by step rotation. ofthef head is eo brou ht a out by means of the whic have a reciprocating motion and engage the ratchets 51 of the disk 511 secured, to and rotating freely with the "head 416.' C Motion is imparted to them through the et pinion 52 keyed to the'same shaft, 53, there-` withf'the horizontal rack 54oi'i'theupper edge of the slidin bar. 55, which'engages the said pinion, an :the corresponding rack 56 in.' the'lower edge thereofat'the oppone@ site end and the segment '5,7 which 1s given oscillating movement by the heart cam 5 8 rotated byv the shaft 23, upon which it `is keyed. rll`he cam 58 receives itsv rotary inotion Afrom the drive shaft 2 2- through thev et idler 29- which meshes with the gear 32 and the gear 33 keyed to the cam shaft', and lthe@L roller 59 mounted on, a stud,` on the segment 57 engages the, cam. The cylinder gear 3 1 also meshes with the gear 3 3v and in this manner receives its motion from the. drive shaft. rlhe sliding bar is mounted in the guides 60 and 61.

ln order to adjust the mandrels er spindles 41 so as to secure a perfect 'alinement with the Plate @et the See-te@ @eeen le:

itt f -the said plateand also oscillated so as to pression o n thetube the head 46 is mountedso that it can be moved bodily to. and from vbring about perfect parallelism between the face of said .plate and the'exterior surfaces of the tubes. This is provided for in the following manner: .The head plate 46 is mounted in one end. of a casing 47 of the head,and in the other end of this casing is mounted a plate 48 through which the in- 1 ner offset ends 44a of the posts 42 extend,

y be secured in any desired. position.

ybeing securedby means of suitable nuts-`49.

. '.Ihis casing is mounted on a round swivel tending into a threaded aperture of the frame is mounted. This screw 38 .is used to move the casing bodily, and the man-` drels, to and from the cylinder 20. Other adjusting screws 39l and 39a extend through the base 37 at right vangles to the screw 38 and bear against a'. depending portion of the head casing to give the casing and the mandrels the oscillating movement on the said base. The entire base of the' casing 37 and the parts supported thereon slide on the dovetail track 34a on the frame in a corresponding slide way 37a in the bottom of said base, and maybe secured at any point by the clamp 36.

i In order to hold the 'tubesin the printing position while the actuating Vpawls 51 are eing retracted, and maintain them, the

` shaft 53, on which the disk 51a bearing the Afio ratchets 51 is mounted, has keyed thereto a cam 15 against which is pressed a roller 6 on a'rockingarm 1,6 by means-of aspring- 7, and a bolt 17 is pressed b a spring 8 into notches' 18a of another dis` 18 keyed'to the said shaft, when the said arm 16 reaches the bottom of the inclined side ofzthe cam,

' -if' the said bolt and one of the notches are in, alinement. The cam is so located that it will cause the rocking armll to retract the bolt, through contact of an extension 9 with'a roller 19 on thebolt, at the end of the backward movement of the spring pawls 50 and permit the same to engage the said notches at the end ofthe forward moveC ment and remain in suchjengagement until the end of the next backward movement.

'As' the outerend of the rocking arm 16 moves inward lat the beginning of the foi'-vv ward motion, the bolt 1 m ust .ride on the outer edge of the disk 18 until another notch 18 is brought into alinement there- --with, which occurs at the moment the tube reaches printing position. 'The spring k8 les -which constantly presses the bolt 17 forward is held in a tubularrecess in the shank cylinder,

of the holt, between the inner end of the said recess and the plate 10. In this manner each tube is held in position while the platel is passing over its surface and then moved to a lower position while another is moved into its place, and each mandrel is held stationary' while its tube is being printed, removed and replaced.

i The operation of the machine will be fully understood by those skilled in the art from the foregoing description.

Various modifications ofthe structural details of the machine may be made, and some of the parts may be changed, omitted or replaced by other parts without departing from the scope of the invention.
