United States Patent PRINTING DIE CONTROL Alva G. Russell, Stamford, Conn., and Walter J. Hanson, Port Chester, N. Y., assignors to Pilney-Bowes, Inc., Stamford, Conn., a corporation of Delaware Application November 28, 1951, Serial No. 258,622 11 Claims. (Cl. 101-91) This invention relates to postage meters and particularly to the projection and retraction of the date and slogan printing dies thereof.
In accordance with postal regulations previously in effect various classes of mail required different printings, and heretofore means have been devised for permitting the movement of either the dater die or both the dater and town dies to non-printing position, and for returning either the town die alone or both the town and dater dies to printing position in order to meet these requirements. One example of such a device is illustrated in the patent to J. W. Ogden, No. 2,179,269, which issued November 7, 1939. Recently revised postal regulations, however, require no movement of the town die and necessitate the retraction of the dater die only.
An improved operating mechanism for town and dater dies (in which the operating mechanism for the dater die is now of particular interest) is illustrated in the application of Berthold Knauer, Serial No. 214,750, filed March 9, 1951, wherein the die operating mechanism not only projects the dater die, but also positively retracts the same when desired.
It has also been the practice in the past to provide the printing members of postage meters with dies bearing advertising matter and known as slogan dies adjacent the postage printing means, which dies could be moved from printing to non-printing position or vice versa at the will of the operator. An example of such a retractable slogan die is shown in the patent to Francis J. Rouan and Earl H. Sorgatz, No. 2,204,971, which issued June 18, 1940.
Heretofore the operating means for the adjustable dies has been directly associated and movable with the rotating printing drum of the postage meter. Thus, the manually engageable control member has normally been housed within the casing which enclosed the printing drum so that the control member would not be inadvertently engaged when the drum was rotating.
The present invention has for its object the remote controlling of the adjustable dater and slogan dies on the movable printing drum in such a manner that the manually engageable control member may be stationarily positioned on the casing where it is easily engageable. The control member will thus be conveniently located where any hindrance to reaching the same, such as is usually oflered by access openings in the housing, is avoided. Furthermore, the location of the manual control member can be used to give a continuously visible indication of the positioning of the adjustable dies Whether the drum is rotating or not.
A feature of the present invention is the provision of manual means for positioning a trip mechanism on a relatively stationary part of the device, together with die moving mechanism on the movable printing drum, the die moving mechanism being actuated by the trip mechanism only in response to movement of the drum.
Another feature of the invention is the provision of a relatively stationary trip mechanism disposable in a plurality of positions to engage a travelling die moving member in a plurality of diiferent ways to accomplish a plurality of different die adjustment settings in response to the relative motion between the mechanism and the member.
Still another feature of the invention is the provision of means on the movable printing member for moving the die moving member slightly more than the movement effected by the tripping mechanism, whereby subsequent revolutions of the drum will occur without contact of the parts so long as the setting of the trip mechanism remains the same.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
A preferred embodiment of the invention is illustrated in the accompanying drawing, wherein:

Fig. 11 is a fragmentary plan View of the meter showing the manually operable control levers and the adjacent legend.
Referring to the drawings, a printing drum 11 is rotatably mounted in a postage meter machine frame or housing 13, and is designed to make one revolution each time i an impression isrequired. The printing portions of the drum 11 are inked and impressed against an envelope, postage strip or other mailable matter during this operation. When the rotation has been completed the drum 11 is compelled to return to a predetermined rest position, which is that shown in Figs. 1, 7 and 9.
The printing drum carries on its surface a number of printing areas such as those provided by postal indicia die 15, town die 17, dater die 19 and slogan die 20. Of these the dater die 19 and slogan die are adjustable so as to be selectively withdrawable from printing position or projectable thereto.
Date! die projecting and i'etracting mechanism The dater die 19 is mounted within the town die 17, and has a lower portion cooperable with cam means 21 on .a shaft23 which.is'rotatablymounted in the drum 11 In..the Secondposition, the .cam means 21is. rotated counterclockwise. 9O?v from .the Fig. 1 position, i. e. so
that. the .circulausurface. of the cam means ZL-is turned to engage and project the dater die 19 to its printing positiornf This is the position used for printing first and fourth-class, mail. canrmeans 21. and .retractingmember 25 are shown and explained in detail in. .the said. .application, Serial Number 214,750, itbeing understood of course, that retraction of .the town.die,17.as provided for in said application is not requi re.d underthe present new regulations, and the town die is arranged to be immovable for continuous printing v The movement of shaft.23 ,whichcontrols. the move mentof cammeansllis controlled by a die actuato1129 mounted on the end of shaft.23. and located at the rear of the drum 11., The, die actuator 29 is shaped so that itsedg es provide cam surfaces which will act ina manner to ,belhereinafter.described. The curved edge 31 when acted upon, provides a projecting cam.,surface and the straight edg e 33 a retracting cam surface.
Onewall 35 ofthehousing 13 has mounted thereon a dater, controllever 37 t.which rocks about the pivot screw 39. One endofthe.levenformsa manually operable finger piece ,41 projecting to the exterior of the housing, and the other end. carries a trip pin 43 which is positionable in two positions in. the path of the die actuator. 29 as the drum 11 rotates, to make appropriate contact with the cam edges 31 and 33. on the die actuator 29 to swing the same in response. to its-motion with the drum,,11, and thereby to adjust the dater die 19--to its printing or non-print position.
A suitable legend. 40, .Fig.. 11,.may be placed on the housing whereby the finger piece 41 acts as an indicator identifying theposition. of..the dater die 19, -or the position which it will.occ upy. at the next printing. Alternatively, the classes of.mail. fo r. which the appropriate The die. partsaand the operation of.

A detent means .(Figs.,3 and 4) is provided for holding thelever 37 in.eith erlof its .two positions. This means includes a pair of positioning recesses 45, .47- in the wall 35, a detent ball 49 looselyheldinan opening 51* in the lev'ep 37, and a fixed leafspringSS. mounted on wall 35 for urging the ball 4-9linto. either .of. recesses I 47.
Associated with the shaft.23.is another detent mechanisn}.54 (Fig. 5) which includesa pairof recesses 55 and in the shaft ,23 and a ball 59: loosely mounted in an opening in the drum 11 and urged by a spring 61 towards engagement .yv tl'l, the shaft23.
The positions WhiQh-thefingerpiece .41 may occupy are mdieated in Fig. 1, ,the position in which the dater d1e ;l9 will not print'being shown in dotted lines.

As thedrum 11 starts to rotate counterclockwise. for the next printing operation the die projecting, cam
surface 31 of the are actuator 29 will ;be,,carried int0 contact with the tripping pin 43 and will cause counterclockwise rotation of the actuator 29 and of shaft 23 as seen in Fig. 8 to produce counterclockwise rotation of earns 21, thereby projecting the dater die 19 to printing position before it reaches the printing point at the bottom of the drum. While the die 19 is shown in printing position in Fig. 2, it will be appreciated that cam 21 and shaft 23 still have about 30? of rnovementbefore they complete their travel. Part of this will be caused by thereaction-of actuator 29engagiug;against pin/l3, but the final increment-of shaft rotation occurs after the actuator clears the pin, and is caused by the spring pressed detent ball: 59 snapping itself into the recess ,57. Thus on subsequent printing revolutions with the pin 43 in the position of Figs. land 2, the actuator 29 will clear the pin by a slight amount and will not cause noise or wear against the same.
When it is desired to print with thedate omittedgthe finger piece 41 is moved to the end 42b of the :slot 42 defining the omit or dotted line position in Fig. 1 which,
corresponds to theleverposition shown in Figs. 9 and 10 When-the printingrotation of drum 11 commences, the
actuator, 29 moves towards the tripping pin 43, thistime engagingthe same. with its ,retractingcam surface 33.
print position. As the die actuator 29. clears the tripping pin 43,'the final increment of itsmovementresults from the detent ball 59 snapping itself intothe recess 55 so that a slight clearance exists between thesurfaces, of
actuator 29 and pin 43 ;on,subsequent rotations of the printing drum 11 until a change in the dater die position,
is again desired,

The slogan die 20 is also movable between printing and nonprint positions as previously explained. The die structure includes a printing niember ;63 from, which three openings therein, 67,69 and 71.
The rod 75" passes through the upper portion of web opening 67 and the rod 77 through the upper portion of webopening 69. Horizontal supporting rods 79 and 81' are mounted at their ends in thesides of the drum 11' (see especially Fig. 4) and pass through the, The rod 791. runs in contact with and acts as a supportfor the bear;-
wehopenings 67 and 69, respectively,
ingrod 75,-whilerod 81 runs in contact with and acts as a support for the bearing rod 77.
A crank arm 83 is mounted to rolatc. \vith a shaft 85 about its axis and moves between the position of Fig. l and a position displaced approximately J80? therefrom. The arm 83'acts as a cam an d rides with its en ds resting. against the edges of the openingfil in the web which acts as a follower. The terminal positions for the arm 83 are determined by the degree to which the rods 79-and 81- can move relative to the openingsland 69 respectively; When the rods are in the upperends of the openings as in Fig. l, the arm 83 has reached 7 the limit of its clockwise movement. Similarly, when the rodsare in the opposite ends of the openings, the arm 83 will have reached the limit of its counterclockwise movement. This oscillating movement of the arm 83 in cooperation with the guiding action oftherods and 77-riding against the rods 79"and 81 causes the projection of the slogan die 20 to printing position, and its retraction therefrom.
The movement of arm 83-is effected byrotation of the shaft. 85. which is-rotatable in the drum 11- and carries at one side thereof a gear..87 The-gear 37' meshes-with a gear 89 also rotatably mounted on the drum radially outwardly of the gear 87 and preferably retained in place against the drum 11 by the flange 88 rigidly connected with the gear 87 which overlaps the teeth of both gears. Rigidly connected to the gear 89 for rotary movement therewith is a slogan die actuator 91 which has two active edges, namely a projecting edge 93 and a retracting edge 95.
The wall of the housing 13 also has mounted thereon a slogan control lever 97 which rocks about the pivot screw 99 and has a finger piece 101 extending outwardly through a slot 102 in the cover 44. The ends 102a, 102b of the slot 102 limit the throw of the lever 97 in either direction. As bestshown in Fig. 4, the lower end of the lever 97 is provided with an opening 103 which receives detent ball 105 and which snaps into one or the other of a pair of recesses 107 and 109 under the influence of a fixed leaf spring 111, the spring preferably being an integral extension of the spring 53. An arm 113 projecting approximately at right angles to the finger piece 101 carries at its free end a trip pin 115 which is positionable in two positions in the path of the die actuator 91 to swing the same in response to its motion with a drum 11, and thereby to adjust the slogan die 20 to its printing or non-print position.
A suitable legend 116 (Fig. 11) may be placed on the housing whereby the finger piece 101 acts as an indicator identifying the position of the slogan 20 which will obtain during the next revolution of the printing drum 11.
An over-center spring means is provided for moving the arm 83 to its full terminal positions, and the same includes a pin 117 on the free end of the arm, to which is connected one end of a tension spring 119. The other end of spring 119 is anchored on a suitable pin 121 fixed to the drum 11.
The positions which the finger piece 101 may occupy are indicated in Fig. l, the position in which the slogan die 20 will print being shown in full lines, and the position in which the slogan die will not print being shown in dotted lines.
Operation of the slogan die control mechanism This results in simultaneous counterclockwise rotation of gear 87 and attached shaft 85 and crank arm 83 as seen in Fig. 8. The edges of the arm 83 acting on the edges of opening 71 shift the die 20 outwardly and to the left as seen in Fig. 2. In this position the die 20 has been moved only part way towards printing position, but with further counterclockwise motion of arm 83 (to a position approximately 180 from that of Fig. 1) the die 20 will lie with its printing surface at the periphery of drum 11, and be ready for printing before it reaches the lowermost or printing position.
While the actuator 91 is designed to initiate the movement of the slogan die 20, it clears the pin-115 before the movement to printing position has been entirely completed. The final movement of the arm 83 towards the left as seen' in Figs. 2 and'8 comes about due to the spring 119 which starts to take effect as soonas the pin 117 has passed to the left of the axis of shaft 85, whereupon the spring. snaps the arm 83 to its terminal position. Through thegears 87, 89 the actuator is also moved far enough by spring 119 so that its surface 93 willbe spaced from the tripping pin 115 during subsequent rotations of the drum 11 to prevent noise and wear.
When it is desired to print with the slogan omitted,
6 the finger piece; 101 is moved to the omit or dotted line position in Fig. 1 which corresponds to the lever position shown in Figs. 9 and 10, against the stop 102a. When the printing rotation of the drum 11 commences, the slogan actuator 91 moves towards the tripping pin 115, this time engaging the same with its slogan retracting surface 95. As the actuator 91 is moved past the tripping pin 115 by the counterclockwise rotation of the drum 11, it is rotated, together with its gear 89 in a counterclockwise direction, as indicated in Fig. 10. This results in a clockwise rotation of gear 87, shaft 85, and arm 83 which moves the slogan die 20 away from printing position and towards its retracted, non-print position. As the slogan die actuator 91 clears the tripping pin 115 it continues its counterclockwise movement due to the pull of spring 119 which has now moved to the right hand side of the axis of shaft and which moves the arm 83 back to the Fig. 1 position. Thereafter a significant clearance exists between the surfaces of actuator 91 and pin on subse-v quent rotations of the drum. 11 until a change in the slogan die position is again desired.
The tendency for movement of the levers 49 and 97 occasioned by engagement of the pins 43 and 115 thereof respectively with the actuators 29 and 91 carried by the printing drum in effecting shifting of the dies on the drum, is arranged to be directed towards the slot ends 42a42b and 102a-102b, thereby to prevent mispositioning of the levers which could render the dieshifting mechanisms inoperative.
