3 Claims. (01. 10191) r This invention relates to an improved mechanism for use in a rotary postage printing and metering device for the combined selective setting of value type wheels and the setting or register actuator mechanism, and more particularly to means whichpermit rotation of settable elements with the printing device during a printing cycle 0f operation.

* In postage printing and metering devices, a 'manual Setting of a value to be printed and registered is effected before starting a cycle of machine "operation. A meter unit comprises a stationary housing wherein the registering mechanism is maintained, and a rotatable printing drum wherein the value type wheels are mounted. Setting of the type wheels and register actuator mechanism is effected by setting levers positioned in the stationary housing. When the drum rotates during a cycle of operation the direct connection between the setting means and rotatin settable elements associated with the rotatable printing drum, which will permit rotation of the printing drum while the setting levers remain stationary. I I I It is another object to provide type wheel setting elements with rack teeth intermediate the ends thereof, and a rotative element with cylindrical rack teeth coinciding with the said rack teeth of the settable elements, also manually adjustable elements with teeth which mesh with therack teeth of the settable elements when setting is effected, the same being arranged to permit the rack teeth --of the setting elements and the cylindrical rack teeth of the rotative element to move throughthe tooth spaces of the teeth 'of the manually adjustable element during a.

As best shown in Fig. 3, the type wheels. H are carried on a shaft I8, mounted within the priming drum llLandeach type wheel has. a pinion l9 connected thereto. Said type wheel pin- .ions 19 are adapted to be adjusted. by longitudinally movable rack bars 2| through intermediate segmental gear members 29, each gear member; including an. outer toothed segment 22 and, an. inner toothed segment 22a. The longitudinally movable rack bars 21 are. slidably mounted within longitudinal recesses 49-40 in the drurn shaft I2, in the manner best shown in'Figs. 3 and" 4, and. are constructed in the manner indicated in Fig, 7., to provide alignment of the rack; toothed, portions thereof, and for their meshed engagement with the intermediate, seg- .m ent gear. portions 22a, The saiclrack. bars 2| extend from the drum. into the meter frame [3 and are located within the drum shaft [2 in pairs, on; oppositesides thereof, in the manner indicated in Fig. 4.

Variable toothed. actuator gears 25 are, mounted: on. scliried. s afts.- 5 which sh t are suitably supported wi h the ra struc ure at-as: best ndicated. in Fi 2;. In; the structu e illus rated. twq. actuator. gears H d 2-511 are mounted on one shaft 26, and 25T and252; are mounted; n. the. other shaft.- and said shafts 25.1-26.- are: positioned on. opposite sides; of; the drum shaft. It, Each; actuator gear.- has. nine groups, of; toothed sectors numbering. from I $919,. andeach gear; is adapted; toabe. adjusted along: its; associated. shaft 26: to move: a desired toothed sector, into operative alignment with an associated six-toothed pinion 21. The sixtoothed pinions 21; mesh with intermediate: gears 28, Fig.

'Each si'ideibar 32' has a tongue: portion: 33 adapted. to.

engage a groove 34 in an associated actuator gear 25, and further has a horizontally disposed rack portion 35 having rack teeth which mesh with the rack toothed portions 24 of the rack bars 2|. Said slidable bars 32 further have rack teeth 3'l, Fig. l, which mesh with associated pinions 38. The said pinionsv 38 are mounted on shafts 39-39, which shafts are supported in suitable bearings 4l-4l, forming part of the frame structure l3.

Setting levers 42 are adapted to be rocked about a shaft 43, which shaft is mounted in bearings 44-44. Each setting lever has a segmental gear: portion 45 joined therewith, which is adapt- 1 ed to mesh with an associated pinion 46, also fixed. to the shaft 39. Hence, any motion of a setting lever from the 0" to the 9" positions will eifect rotation of the pinions 46 and 38 to move the slidable members 32 and thereby efiect adjustment of associated actuator gears 25 and rackv bars 2|.

The use of six-toothed pinions 27' with. the actuator gears25 provides a substantial choke, to prevent overthrow, as, will. be, noted in Fig. 8, butv when a drive of the pinion is affected as indicated in Fig. 9,, the first tooth, of the pinion will have movedthrough a distance equivalent to a two digit count, while the first tooth of the gear has moved only the distance of one tooth. This will be clearly observed by the position of the shaded tooth of the pinionin Figs. 8,9 andl0.

In. view of. such two-toothed movement of. the pinion for one-tooth movement. of. the gear, the actuator gear will require only asingle toothto effect a count of two, and. in the, same, manner two teeth will eifect. a count of three, three teeth will effect a count of four,. etc; To produce a count of one with said actuator. gear, a special one-toothed gear portion is provided, as indicated at 43, and a separate pinion is provided at 49 in such manner that when an actuator gear 25 is moved to effect a one-tooth. setting, the one-toothed gear portion 48 will. become. aligned with. the pinion 49.. Referring to Fig 11,,it. will be. noted that theone-toothed gear portion 48, has no choking. surface relative to the teeth of, the pinion 49.. Hence thepinion49 does nottake the same relative position, as the pinion,2-.| and as. aresult the effective operation. of the onetooth gear, portion will 0n1y produce, one, tooth rotationof the pinion 49;.'. Choking isadapted to beeffected however, through pinion 2:7, which, during the one-tooth setting, is in alignment witha depression, 5| in the-actuating, gear; 25 and is so positioned that,when the one -toothedd'rive is. efiected, a tooth.- of an. associated pinion 21 will engage the depression '5! in the manner indicated in Fig- 12.. After; the one-tooth operation, the teeth of the pinion. will effectchoking across the choking; surface ofr the.- actuator gear in the same mannerasshownin Fig- 8;

The setting of a value. forprinting will; be

' effected, whensetting: lever 4-2t'is;ro,tated about the shaft; 43, which, rotation willeffectmWement of an associated gear segment 45 and; pinions 4B; and 38 to thus move; an associatedslidable bar 32. Movement} of. said slidable; barr 3.2; will operative; relationwith an ssociat dpinion.

and said value will be entered in the registering mechanism l5 when the teeth of the actuator gears 25 actuate the intermediate gears 28-28 a and gearing 29-29a.

' It will be noted that each of the first four register wheels is adapted to be driven directly by an associated actuator gear. This may be accomplished by means of planetary differential gearing within each register wheel, such as disclosed in Figs. 13 and 14. The drive from an actuator gear 25, through associated gearing to the pinion 29a, will effect the drive of a sun-gear 62. Another sun gear 53 is normally held fast,

' as a result of a Geneva transfer connection with a numeral wheel of lower order. Therefore, the planetary gears 54 and 55 will rotate around the sun gears 52 and 53 respectively. With the planetary ears 54'. and 55 mounted in the numeral wheel casing, the numeral wheel will rotate when the planetary gears rotate.
