- type adjustment wheels 31, 32, 33 by means of push buttons, or equivalent push means, is conductive to a great uniformity of operation of type adjustment Wheels 31, 32, 33.
- the strength of the impact of the finger of the operator of the postage meter upon push buttons 10, 11 12 does not affect the operation of type adjustment wheels 31, 32, 33 and, however hard the impact of the finger of the operator of the postage meter upon push buttons 10, 11, 12 may be, type adjustment wheels 31, 32, 33 will be moved smoothly and none of type adjustment wheels 31, 32, 33 will ever be pivoted more than a distance equal to the pitch of pins 40 and notches 39, respectively, incident to one finger stroke performed by an operator of the meter.
- Type wheels 19 and 20 need only to be adjusted once a year. In view thereof no push buttons are provided on the outside of frame and housing structure 52 or cover plate 6, respectively, for adjustment of these two type wheels. Their adjustment can be effected by means of operating members upon removal of the entire printing.
- knob 64 in one direction will raise plates 2, 3 and all the parts supported by plates 2, 3 including cover plate 6,'
- knob 64 in the reverse direction will lower plates 2, 3 and thus move type wheels 16, 17, 18, 19 and 20 back to the printing plane.
- the upper end of rod 49 is provided with an abutment screw 56 whose shaft is coaxial to rod 49 and screwed into an axial internally screw-threaded bore in rod 49.
- knob 64 Rotation of knob 64 in the direction for raising plates 2 and 3 results in engagement of the aforementioned shoulder by the head of screw 56, thus limiting the upward motion of tubular nut 53 and that of sleeve 5 and plates 2, 3 and of all parts which are supported by them.
- sleeve 5 and plates 2, 3 are raised automatically to the non-operative position of type wheels 16, 17, 18, 19 and 20 under the bias of helical spring 54.

Frankfurt am Main, Germany Filed Dec. 20, 1965, Ser. No. 524,664 9 Claims. (Cl. 101-99) ABSTRACT OF THE DISCLOSURE Disclosed is a printing mechanism intended to form an integral part of a postage meter. The printing mechanism is designed to form a self-sustained structural unit that can be inserted as a unit, and removed as a unit, from a frame or housing structure. Thus the printing mechanism can be serviced and cleaned separate from the postage meter in conjunction with which it is intended to be used.
This invention refers to postage meters, and more particularly to the date printing mechanism thereof.
It is a general object of this invention to provide postage meters having improved date printing mechanisms.
Postage meters comprise a printing plate for printing intelligence which is fixed, i.e. which does not change from time to time, or does not change with each consecutive day. In addition thereto postage meters comprise adjustable date type means for printing the particular mailing date which changes with each consecutive day. As a general rule, the printing plate for printing intelligence which is fixed has an aperture, and the adjustable type means for printing varying mailing dates have printing surfaces arranged inside of the aforementioned aperture. The adjustable type means for printing varying mailing dates are under the control of handles, levers, or equivalent manually operable means which are accessible from the outside of the frame and housing structure of the postage meter.
The date printing mechanism of postage meters which are being extensively used tend to get soiled by particles of paper, dust, and particles of pigments which are being carried to all points of the date printing mechanism as the same is being adjusted daily to print the respective date. The grime and dirt being carried around in the date printing mechanism of prior art postage meters is a serious source of trouble because the formation of grime and dirt is unavoidable, and because in prior art postage meters the date printing mechanism is not readily accessible for cleaning.
It is, therefore, a special object of this invention to provide postage meters not subject to the above limitations and drawbacks, i.e. postage meters having adjustable date type means and parts which are operatively related to said date type means which can readily be removed from the postage meter for cleaning.
According to the present invention the adjustable date type means and the gear means for their adjustment are integrated to form a self-sustained structural unit so that the adjustable date type means and the gear means for adjusting the same are jointly insertable as a unit into, and jointly removable as a unit from, the frame and housing structure of the postage meter.
For a better and more complete understanding of the invention reference may be had to the ensuing particular description thereof, as illustrated in the accompanying drawings wherein FIG. 1 is partly a side elevation and partly a vertical section of a postage meter embodying the present invention, and more particularly of the date printing mechanism thereof;
FIG. 2 is a front view of the structure shown in FIG. 1;
FIG. 3 is a top plan view of the structure of FIGS. 1 and 2;
FIG. 4 is a section of the structure of FIG. 1 taken along 5-5 of FIG. 1;
FIG. 5 is a section of a portion of the structure of FIGS. 1-4 taken along 5-5 of FIG. 1;
FIG. 6 is partly a side elevation and partly a vertical section of a postage meter embodying the present invention, and particularly of the date printing mechanism thereof different from the structure shown in the previous figures; and
FIG. 7 is a front view of the structure of FIG. 6.
Referring now to the drawings, and more particularly to FIGS. 1 to 5 thereof, numeral 52 has been been applied to indicate the frame and housing structure of a postage meter. The postage meter may be of any conventional design, and its mode of operation may likewise be conventional. The meter according to this invention diifers from prior art postage meters only in regard to the date printing means thereof. Printing plate 58 is fixedly arranged at the bottom of the frame and housing structure 52 and thus for-ms an integral part thereof. Printing plate 58 is intended to print intelligence which does not vary from time to time as, for instance, the postal mailing district, the name of the sender of the mail, advertising matter, etc. Printing plate 58 is provided with an aperture 58 in which aperture adjustable date type means are arranged. The types forming part of these date type means and the types of the aforementioned printing plate are arranged in a common printing surface or printing plane.
Each of type wheels 16, 17, 18 is provided with a toothed gear 22 in meshing engagement with a corresponding toothed gear 27 mounted on shaft 29. Toothed gears 27 are, in turn, in meshing engagement with a cor responding set of toothed gears 28 mounted on shaft 30. Toothed gears 28 are in meshing engagement with a set of toothed gears 41 mounted on shaft 36. Shaft 36 has substantially the same configuration as shaft 24, i.e. both are substantially in the shape of a roller or, in other words, both have a relatively large diameter. Each of gears 41 is fixedly connected for joint rotation with one of a set of type adjustment wheels 31, 32 and 33 mounted on shaft 36. Wheels 31, 32 and 33 are pin wheels, i.e. each of them is provided with equidistantly arranged, radially extending pins 40. Type adjustment wheels or pin Wheels 31, 32 and 33 are substantially annular and the inner surfaces thereof are provided with a plurality of V-shaped recesses or notches 39. The number of these notches 39 is equal to the number of signs on the radially outer surface of each type adjustment wheel, and the number of signs on the outer surface of each type adjustment wheel is equal to the number of types on a corresponding type wheel 16, 17, 18. A small ball 38 is provided for arresting each type adjustment wheel in one of its several operating positions, each ball 38 being biased radially outwardly by a biasing spring 37 arranged in a radially extending bore in shaft 36.
Push buttons 10, 11, 12 movably arranged inside of apertures 7, 8, 9 are provided for operating adjustment wheels 31, 32, 33 and thereby adjusting type wheels 16, 17, 18. The lower end of theshaft of each push button 10, 11, 12 defines a slot 44 receiving a pin 46. Pins 46 are supported by a bridge plate 4 whose ends are fixedly secured to vertical plates 2, 3. Pins 46 and slots 44 perform two functions, i.e. they guide push buttons 11, 12
4 along straight paths and they limit the length of said paths.
The shaft of each push button 10, 11, 12 supports a pin 66 which, in turn, pivotally supports a ratchet 45 under the action of a biasing spring 47. The ratchet 45 associated with each push button 10, 11, 12 operates the pin 66 which, in turn, pivotally supports a ratchet 45 one of the push buttons 10, 11, 12 is being depressed, the slanting front edge of the ratchet 45 associated with the particular push button engages a pin on one of the type adjustment wheels 31, 32, 33 operatively related to the particular push button. This results in a pivotal motion of the ratchet 45 (in counterclockwise direction as seen in FIG. 1) and in tensioning the biasing spring 47 connected to the particular ratchet 45. Each push button 10, 11, 12 is biased in upward direction by a helical spring 43 surrounding the shaft thereof. Upon release of the particular push button that had been manually depressed by the action of the finger of the operator, the push button returns to its initial position under the action of its helical biasing spring 43. This causes the upper edge of one of ratchets 45 to abut against one of the pins 40 of one of the type adjustment wheels 31, 32, 33 and to pivot that type adjustment wheel a predetermined angle. Each push button 10, 11, 12 is provided with a boss 48 forming an abutment for one of the ratchets 45 during the upward movement of the respective push button under the action of its biasing spring 43.
The pivotal motions of type adjustment wheels 31, 32, 33 are transmitted by means of gears 28 and 27 to the corresponding type wheel 16, 17, 18, resulting in the desired adjustment of type wheels 16, 17, 18 for printing out any month of the year and two digits indicative 0 any particular day in that month.
The indirect mode of operation of type adjustment wheels 31, 32, 33 by means of push buttons, or equivalent push means, is conductive to a great uniformity of operation of type adjustment Wheels 31, 32, 33. To be more specific, the strength of the impact of the finger of the operator of the postage meter upon push buttons 10, 11 12 does not affect the operation of type adjustment wheels 31, 32, 33 and, however hard the impact of the finger of the operator of the postage meter upon push buttons 10, 11, 12 may be, type adjustment wheels 31, 32, 33 will be moved smoothly and none of type adjustment wheels 31, 32, 33 will ever be pivoted more than a distance equal to the pitch of pins 40 and notches 39, respectively, incident to one finger stroke performed by an operator of the meter.
inclusive, is designed to meet this requirement. Turning of knob 64 in one direction will raise plates 2, 3 and all the parts supported by plates 2, 3 including cover plate 6,'
and thus move type wheels 16, 17, 18, 19 and 20 out of the printing plane. Turning of knob 64 in the reverse direction will lower plates 2, 3 and thus move type wheels 16, 17, 18, 19 and 20 back to the printing plane. The upper end of rod 49 is provided with an abutment screw 56 whose shaft is coaxial to rod 49 and screwed into an axial internally screw-threaded bore in rod 49. As long as the type wheels are in their lower position, or printing position,.there is a predetermined clearance between the lower surface of the head of screw 56 and a shoulder formed inside of knob 64 by virtue of a cavity provided therein.
Rotation of knob 64 in the direction for raising plates 2 and 3 results in engagement of the aforementioned shoulder by the head of screw 56, thus limiting the upward motion of tubular nut 53 and that of sleeve 5 and plates 2, 3 and of all parts which are supported by them. Upon appropriate operation of knob 64 on nut 53, sleeve 5 and plates 2, 3 are raised automatically to the non-operative position of type wheels 16, 17, 18, 19 and 20 under the bias of helical spring 54.
If it is desired to remove nut 53, sleeve 5 and plates 2, 3 and all the parts which are supported by the latter form the frame and housing structure 52 of the meter in order to clean the date printing mechanism, and the parts which are associated with it, or for some other reasons, this calls for a removal of abutment screw 56 from the cavity inside of knob 64.
Any removal of the date printing mechanism from a postage meter should be performed only by qualified and authorized personnel rather than by any person who may have access to, and may use, the postage meter. In order to preclude unauthorized access to abutment screw 56, which is a prerequisite to removing the date printing mechanism from the postage meter, the entrance portion of the cavity inside of knob 64 is sealed by a seal 60 of soft metal, such as lead, which abuts against a supporting disc 59 resting on an upper shoulder defined by knob 64 and locked in position by virtue of a circular groove 61 in knob 64 forming an abutment for a toroidal projection on seal 60 entering into and engaging groove 61.
When knob 64 is turned in the direction causing lowering of tubular screw nut 53 sleeve 5 and plates 2, 3, the lower end of plate 2 engages a shoulder 55 formed by the frame and housing structure 52. Engagement by plate 2 of shoulder 55 precludes any pivotal motion of the unit 5, 2, 3 and of the parts which are supported by plates 2, 3 about rod 49.
It will be apparent from the foregoing that plates 2, 3 are parallel, and arranged at right angles to that portion of the frame or housing structure to which reference numeral 52 has been applied. Shafts 24, 29, 30 and 36 are arranged within a space bounded by plates 2, 3 and rod 49 extends parallel to plates 2, 3.
The structure shown in FIGS. 6 and 7 is, in part, the same as that shown in FIGS. 1 to 5 and the same reference characters have been applied in all figures to designate like parts. In view thereof FIGS. 6 and 7 call for a detailed description only to the extent to which the structure shown therein difi'ers from that of FIGS. 1 to 5.
The structure of FIGS. 6 and 7 includes a vertical, externally screw-threaded rod 49 supporting sleeve 5 which, in turn, supports a pair of vertical spaced plates 2, 3. It will be observed that vertical plate 2 has been deleted in FIG. 6 to expose to view the parts of the structure which are arranged between plates 2 and 3. The upper screwthreaded end of rod 49 supports the elongated screw nut 53 projecting beyond the cover plate 6 through an aperture a in the latter and forming an operating knob 64 at the end thereof projecting beyond cover plate or cover panel 6. The two parallel spaced plates 2, 3 are secured to sleeve 5 by means of four screws 65. Plates 2, 3 support but two shafts 24 and 36 of which the latter supports adjustment wheels 70, 71, 72. The periphery of adjustment wheels 70, 71, 72 is preferably knurled to facilitate the operation thereof. Each adjustment wheel is provided with a pulley 73 for supporting an endless belt, and these pulleys form integral parts of adjustment wheels 70, 71, 72. Each pulley 73 is annular and defines on the inner surface thereof a system of V-shaped recesses or notches 39 having a predetermined pitch. Shaft 36 defines radial recesses or bores, each housing a helical spring 37 biasing a ball 38 radially outwardly into any of the systems of V-shaped recesses or notches 39.
The lower shaft 24 supports a plurality of pulleys 74 of which each corresponds to, and is identical with, one of the pulleys 73 supported by the upper shaft 36. Each 6 of the pulleys on lower shaft 24 is annular and forms on the inner surface thereof a system of V-shaped recesses or notches into which a spring-biased ball may enter to arrest the respective pulley in a predetermined position.
The type mechanism and type adjusting mechanism of FIGS. 6 and 7 may be removed from the frame and housing structure 52 in the same fashion as described in com nection with FIGS. 1 to 5, inclusive, in considerable detail.
It is also possible to raise the type surfaces of printing belts 75M, 75Z, 75E and 751 above the printing plane, and to thus render the date printing system inoperative in the same fashion that has been described in considerable detail in connection with FIGS. 1 to 5, inclusive.
