y 1952 M. w. WARREN ETAL LOST MOTION DRIVE FOR ROTARY PRINTING DEVICES Filed Feb. 12, 1949 Patented July 15, 1952 LOST MOTION DRIVE EoR EoTARY trnnv'rnvc DEVICES a Y Y ration-of New"Yoi-k .-.ApplicationEebruary 12, 1949, SeriailNdl76J06 "2Claims. (Cl. 101219) The present "invention relates to printing devices, and has special reference to devices for repeatedly applying a code marker other designation on a web of labeling or wrapping material previously to the web being cut 'into separate labels or wrappers, each wrapper bearing the designation in a specificlocation.

The principal object of the'invention is toprovide a device of this character which issimple in construction and convenient'inuse, and which insures proper location of the indicia irrespective of variationsi'n speed of theifeeding of the web.

Another objectof the invention is to provide a device of this'characterjin whichlthe'fltype may be easily removed and replaced, thus enabling various distributors code or other indicia to be printedwithout the trouble and expense of maintaining on hand stocks of labels or wrappers and the necessary engraving.

The several features of the invention, whereby these and other objects may be attained, will be readily understood from the following description and accompanying drawings, in which:

Figure 1 is a side view, with certain parts "brokenia'way of a printing idevice shownoperat Fig. 3 is a sectional view, taken on the line 3-3 of Fig. v2; ,and

Fig. 4 is a view in perspective of a package of chewing gum with a code marking printed on'the label or wrapper thereof by the device.

The printing device illustrated in the drawing is particularly adapted for repeat printing a code mark or other designation 2 on a web of cellophane or other wrapping or labeling material 3 as the web is fed to cutting-off knives which sever the web into separate wrappers to be subsequently wrapped about the chewing gum or other articles. The code mark 2 is printed in a specific location on the label or wrapper of each chewing gum or other package (Fig. 4).

As shown the device comprises a type-carrying roll 4 arranged adjacent one side of the web. This roll is mounted on a shaft 6 that has one end journaled in a bearing in one of the side frames 1 and its other end journaled in a bearing in a bracket member 8 detachably secured in a recess in the other side frame 1 by means of a cap screw 9 and a pin H1. The roll 4 is connected to the shaft 6 through a pin l i, the ends of which extend into slots l2 in the roll. The type l3 which is of rubber is cemented on a separate insert M which "potor reservoir '22, 'a doctor blade '23 beingassooiated iththe ro11'2i. Thesha'ft'Zll through its other ends is driven in" timedrelation'tothe, normal feeding of the web 3 and theweb severing and wrapping devices of the .machine. As the 'niechanismfor'drivingthe shartzu forms no part of" thepresent'invention, the same is not shown in the drawings. 1

The device is further'providedwith"a platen roll 2 which is mounted to turn-on astud' shaft Q abet'ween collars-securedthereon. The shaft 26 is secured'tojor made'integral with 'a-screw 30 that is screw-threade'din' an aperture in one of the "side frames 1. The shaft 26 has :its axis arranged slightly eccentrically of the axis of the screw 38 so that -by"-turning' the "screw slight adjustments of the platenroll24 maybe-made in L a direction toward andfrom "the web '3.

With "this construction,;tduring the normal operation of the devi-cewithtthe web '3 driven at the same speed "asthe' surface speed ;of the type i 3-,, the inked'type'engages the web 3 so. as-to print the desiredindicia in a specific location on each wrapper design-portion of-'thefweb'iduring each revolution ofthe type 1e11, the resilienttype by applying pressure to the platen roll 24 through the web, causing the platen roll to rotate therewith. As the type l3 projects a distance beyond the surface of the roll 4, as it passes out of engagement with the web the remaining surface of the roll is free of the web. The pressure exerted on the web by the type I3 and platen roll 24 may be varied by adjustment of the screw 30.

In wrapping machines such as gum wrapping machines in which there is repeat printing of a label design on the web fed to the machine, the

speed of the web is commonly controlled by means of an electric eye so as to vary its speed to compensate for imperfect printing, thus insuring the individual labels or wrappers being cut off at the proper points by the cutting-01f knives of the machine.

In the present device, in case the speed of the web 3 is thus increased by the electric eye, upon the type I3 engaging the web the pin and slot connection between the type carrying roll 4 and its shaft 6 enables the speed of said roll to be 1,2 a ;L 3 correspondingly increased due to the pressure of the type and platen on the web, and thus the type is caused to travel at the same speed as the web until the type passes out of printing engagement with the web. After the type thus disengages from the web, saidpin and slot connection permits the shaft to again pick up the roll and drive it at its normal speed, and thus cause the type 13 to again engage the web at the completion of one revolution thereof. Thus irrespective of any increased speed of the web the type moves at the same speed as the web when printing and the printing is applied ate. specific location on.

each label or wrapper designij,

It will be apparent that t ecomplete printing roll can be very readily removed, and the rubber type mounted on the separate insert, may be removed for quick change. By providing extra printing rolls and extra inserts on which the rubber type is cemented, a minimum change time is required for changing the customers code mark, date, or other designation.

The machine is simple in construction and convenient in use, and is of small size so that it may be installed in a restricted area. For convenience of illustration, the views of the drawings are enlarged but in the actual device used in association with a machine for wrapping five cent packages of chewing gum with cellophane, the

our invention permits various modifications without departing from the spirit thereof or the scope of the appended claims. a
