B. mom. the test both trevel oi the ortlcles continues in the some direction about the struction and operation, a description of one,

of them is all that is necessary, and from this point on the description of the invention, its construction and operation will deal, for the most part, with only one of these mechanisms, except where necessity requires otherwise.

Accordingly, and referring to Figure 3 of the drawings, it will be. seen that the previously mentioned mandrel tracks l2 are omitted or interrupted at the printing station, and that during passage through the printing mechanism, the mandrels 9 are supported by a leather covered auxiliary track portion I3 which is vertically adjustable as desired by means ofscrews or the like I4 carried by brackets I5 secured to and extending laterally from angle rails I 6 which underlie and support the conveyor I through its cross bars I during the greater extent of the lower course of travel of said conveyor. In order to preventwabbling of the conveyor and mandrels during passage thereof through the printing mechanism, the cross bars I of the conveyor l are held firmly upon the rails I8 by members II which are suspended from the main frame structure I8 and vertically adjustable in order that their pressure uponv said bars i may be regulated.

Mounted transversely of the apparatus is a printing mechanism drive shaft 20. This shaft 20 is journaled in bearings 2| an has secured thereon a sprocket wheel 22 which is rotatably driven by the conveyor I through engagement of the pins 3 thereof with the teeth of said wheel 22. Also secured on the drive shaft 20 is a smaller sprocket wheel 23, and through a chain 24 this sprocket 23 drives another sprocket wheel 25 secured on a shaft 26 which is rotatably journaled above and parallel to the said drive shaft 20,

Secured on this shaft 26 is a pulley 2''! for driving a belt 28 which is passed about said pulley 21 and also two idler pulleys 23 rotatably mounted upon stud shafts 30 and positioned so that the belt 28 thereon engages downwardly upon the base portions II of the mandrels 3 so as to rotate the latter during their passage this is periodically actuated to rotate the said shaft 33 in a counterclockwise direction (reference being had to Figure 3) by means of a pawl 38 which is pivotally carried by a collar 39 journaled on the shaft 33 and operated by a link 40 driven from an eccentric crank 4I secured on a shaft 42. The other or inner end of this shaft 42 carries a gear 43, and this gear 43 meshes with'a gear 44 on the main driving shaft 20.

The shaft 42 is thus driven from the main shaft 20 in timed relation therewith, and hence in timed relation with the travel of the conveyor I and the ratios of the various driving connections between the conveyor I, the main shaft 20 and the shaft 42 are such that the pawl 33 actuates the ratchet 3'! and the shaft 33 so that the printing pads 36 on the hexagonal faces of the printing roll 32 are successively brought into upwardly facing printing. position as each succeeding mandrel 9 with its article passes the printing point.

A roll 45 for applying ink to the several printj adjustably mounted arm 53 for supporting a weight 54 that may be moved therealong to regulate the pressure of the roll against the inking roll 45. Ink may be applied to the roll 53 either manually or from a fountain or like supply as desired.

When it is desired not to print any matter upon the articles carried by the mandrels 9, the

latter may be caused to pass through the printing mechanism without contacting the printing roll 32, for example, by providing a bracket 55 having thereon a traction surface 56, and arranging the said bracket so that it can be elevated, thus causing the surface 56 to engage the hub p01 in II of said mandrels 3, thus likewise raising the latter. This bracket 55 is biased downwardly upon a wedge-shaped lever 51 by a spring 54, and hence elevation of said bracket and the mandrels 8 may be effected by manually moving said wegige-shaped lever 51 further beneath the bracket From the foregoing description, it will be observed that the present invention provides a novel mechanism for applying printing upon a continuously moving succession of articles and,

. in the particular adaptation of the invention ilwith the printing roll or platen 32 with enough 3 a drive shaft :3 rotatably iournaled in bearings 34 and 35.. This printing roll or platen 32 is polygonal in shape, thus providing aseries of flat peripheral surfaces upon each of which is secured a printing pad 35. The printing roll shaft 33 has secured thereon a ratchet 3 1, and

such a printing mechanism has been herein illustrated and described, it is not intended that the invention be limited to such disclosure, but that changes and modifications may be embodied and incorporated therein within the scope of the annexed claims. I
