CODE DATER Filed Aug. 3, 1959 ited States Patent Oiiice 3,64,566 Patented Nov. 26, 1%52 spouses cons eArER Robert F. McVielrer, Anderson, Ind., assiguor to Lynch This invention relates to a code dater particularly adapted for dating cartons passing through a cartoning machine.

One object of the invention is to provide a code dater including a date stamp holder which may be readily snapped out of and back into position, thus reducing the down time necessary to effect a change of code date to a minimum, particularly when two of the holders are used, one with the new date stamps to replace one that is removed, after which the date of the removed holder may be changed whenever convenient for use the following day. Thus the cartoning machine is not out of service while such change is being effected.

Another object is to provide a date stamp holder carrier and a date stamp holder so associated with each other that the holder may be readily snapped out of position with respect to the carrier and snapped back into position again without the necessity of removing and/ or replacing a fastening means such as screws or the like.

More particularly it is my object to provide a date stamp holder that has a tongue and groove cooperation with a date stamp carrier, combined with a dovetailed connection at one end of the date stamp holder and a spring detent connection at the other end permitting the introduction of a screw driver or the like to pry the holder out of the carrier, the dovetailed connection and opposed spring detent eificiently holding the holder in position with respect to the carrier when it is re-inserted.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my code dater, whereby the objects above contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in detail on the accompanying drawing, wherein:

FIG. 1 shows an end elevation of a date stamp holder carrier and an opposed backup roller, with my improved date stamp holder associated with the carrier, and illustrates the operation of the dater on a carton;

FIG. 2 is a side view as taken from the right side of FIG. 1 showing the upper part in cross section for illustrating details;

FIG. 3 is an enlargement of a portion of FIG. 1 showing the removal operation of the holder relative to the carrier;

FIG. 4 is an enlarged vertical sectional view on the line 4-4 of FIG. 1 showing further details; and

FIG. 5 is a perspective view of the date stamp holder.

On the accompanying drawing I have used the reference numeral to indicate in general a date stamp holder and 12 a date stam holder carrier. The holder 12 is suitably clamped to a rotating shaft 14 that rotates once for each carton C fed through a wrapping machine, and is opposed by a backup roller 16. The roller 16 preferably has a hard rubber face 18 to absorb the shock of multiple cartons passing though the machine and prevent excessive wear on the dating dies. It also evens out the difference in height of the dies and gives a uniform dating imprint on the carton C.

The backup roller 16 is rotatable on a bearing sleeve 28 that has an eccentric bore surrounding a stationary shaft 20. The sleeve 28 is provided with a clamp block 22, clamp screw 24 and clamp nut 26 to clamp the sleeve 28 in any desired adjusted position on the shaft 20, thus permitting adjustment of thecoacting face of the hard rubber 18 toward or away from the carrier 12 and holder 19 as they rotate with the shaft 14 depending on the thickness of the carton C and the desired pres sure of imprint of dating stamps on the car-ton as will hereinafter appear. This adjustment also permits takeup for wear.

The date stamp holder 10 ismounted in the carrier 12 by means of a key 34 received in a slot or groove 36 of the carrier 12 so as to properly align one with re spect to the other as obvious by an inspection of FIG. 4. One end of the holder 10 has a dovetail projection 38 adapted to interfit with a dovetail notch 40 in the carrier 12, as shown in FIGS. 1 and 3, while the other end is provided with a depression 42 to coact With a detent ball 44 backed by a detent spring 46. The spring 46 and the ball 44 are carried by a detent carrying screw 48 which permits desirable adjustment. Such adjustment is retained by a friction plug 49.

The holder 14} is also provided with a flange 56 with which a screw driver blade 58 may be associated as shown in FIG. 3 to pry the holder out of the carrier so that fastening elements such as screws or the like do not have to be removed and replaced. Thus my construction makes the job of changing dates relatively quick and efiicient. The dating dies are shown at 52 and are received in date stamp bores 50 of the holder 10, being retained in position by set screws 54.

Inasmuch as the change of date on the dater usually involves the changing of one or more of the date stamps 52, down time of the wrapping machine can be reduced to a few seconds by having two of the holders 10 and snapping one with the old date out and the one with the new date in, after which the date stamps 52 can be changed at any time before another change of date is required. Thus, I have provided a simple and efiicient code dater for use in connection with wrapping machines, cartoning machines and the like, which reduces date-change time to a minimum.

Some changes may be made in the construction and arrangement of the parts of my code dater without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may reasonably be included within their scope.

1 claim as my invention:

1. In a code dater of the character disclosed, a rotating shaft, a date stamp holder carrier, a date stamp holder mounted therein, date stamps carried by said date stamp holder, said carrier being mounted on said shaft, a backup roller opposing said date stamp holder and having a hard rubber face for the passage of a carton to be dated between said face and said date stamps, said holder having key and slot cooperation with said carrier, a dovetailed connection with said carrier at the trailing end of said holder which tends under operation to more firmly seat said connection, detent means to retain the leading end of said holder in position relative to said carrier, an adjusting screw carrying said detent, said screw being carried by said date stamp holder carrier said carrier having a projection overhanging a portion of said carrier but spaced therefrom to permit a screw driver to be inserted between said portion and said projection for disengaging said holder from said detent means to permit ready removal and replacement of said holder relative to said carrier.

2. A code dater comprising a shaft, a date stamp holder carrier mounted thereon for rotation therewith, a date stamp holder removably associated with said carrier, date stamps mounted in said holder and a backup roller opposing said date stamp holder between which, and

said date stamps, a carton may be fed for being dated by said date stamps, said date stamp holder comprising a segment having a tongue and groove connection at the bottom thereof with said carrier, said tongue and groove connection permitting radial association of said date stamp holder with said carrier and extending in the plane of rotation of said carrier, a dovetailed connection at the trailing end of said holder tending under operation to seat said trailing end more firmly in said connection and a. spring detent connection at the leading end thereof permitting ready removal and replacement of said holder relative to said carrier, and an adjusting element threaded in said date stamp holder carrier and carrying said spring detent.
