11 Claims.

This invention relates to postage printing and metering machines, and more particularly to that type of postage printer known as the Multi- Denominational machine, in which several dies,

representing different denominations, may be selectively positioned to impress postage indicia on envelopes, cards, or other mail matter.

In general, the machine is that type which includes a metering mechanism for indicating and registering the amount of postage paid for and used by the machine; locking devices designed to prevent operation of the machine when a predetermined amount of postage has been printed on '1 mail matter; and means for operating the several mechanisms.

The users of these machines purchase a desired. amount of postage from a representative of the Government, who sets the metering mechanism. When the counter wheels of the meter have made a predetermined number of revolutions, the machine is automatically locked against further use and can be made operable only after the meter has again been adjusted by prepayment for ad ditional postage.

Specifically, the present invention relates to means for timing the engagement of the impression roll with the mail matter as it is stamped and for regulating the pressure of the roll on the mail matter. The invention further includes novel means for shifting the timing means from a single impression of a stamp with the ring die to one in which the ring die is omitted and vice versa.

The machine and its operation will be more fully understood from the following description thereof taken in connection with the accompanying drawings, in which:-

Fig. 1 is a perspective view of the assembled machine, a portion thereof being broken away to illustrate the impression roll;

Fig. 2 is an elevation, partly in section, showing the relative positions of the several parts of the machine;

Fig. 3 is a bottom view of the machine, showing the drive therefor;

Fig. 4 is a partial section taken on line 4-4 of Fig. 3;

Fig. 5 is a back view of the machine, a portion of the base thereof being broken away to iilu trate the drive and gearing, and the back plate of the switch housing being removed; and

Fig. 6 is an elevation of means for locking the machine when not in use.

Referring to the drawings, the machine comprises a base having an upwardly extending rooklyn, N. 1., a cor 1936, Serial No. 59,298

gear housing preferably cast with the base and having flanges ll designed to form a'partial support for the meter housing iii thereon. The meter housing Ed has formed therewith a sub stantially cylindrical extension 2i providing a housing for the printing die 2'2.

Mounted on base is and lying in a plane below the printing die is a feed table to which is fastened a removable plate 23' carrying a well for water. A removable tongue carries a depending moistening device (not shown) whereby, as the mail matter is fed through the machine, it is automatically sealed, in addition to having postage indicia printed thereon.

An opening 25 permits inking roll 26 to be pressed against the die, as the latter rotates, and to ink the surface thereof before the indicia is printed on the mail matter. ink roll 2% is pivoted on a slotted arm 2i which may be adjusted with respect to the die by means of a bolt and thumb nut 28 passing through a bracket 29. Guard 3! surrounds a substantial portion of the ink roll. A strip of spring metal the tension of which may be adjusted by a threaded tension piece 33, holds the mail matter against the table in its passage through the machine and, supplementing the pressure of the impression roll, furnishes additional pressure to seal the envelopes which have previously been moistened by the moistening de vice. Further reference will be made to this spring hereinafter.

While the machine is adapted to be driven by hand, in the present form of the invention an electric drive is illustrated. Motor 34, initially controlled by switch drives shaft through suitable gearing. A ratchet member til on shaft 36 is adapted to be engaged by pawl 38 pivoted to plate 39. Spring M tends normally to force the pawl into engaging relation with the ratchet teeth.

Plate 39 is fastened to or is formed with sleeve 42 to which is also fastened bevel gear Shaft is journaled in a bracket Ml secured to the base of the machine. Meshing with bevel gear 43 is a second bevel gear 4 secured to shaft 46 to which is also fastened gear 4?. A slotted sleeve 43 is secured to shaft Mi, the sleeve forming one end of a universal joint comprising rod 49 and a slotted sleeve 5|, the latter driving an impression roll, to be described hereinafter. Gear 41 meshes with pinion 52, and the latter, in turn, meshes with a gear 53 fixed on shaft 54.

Pivoted to bracket 55, which is secured to the base of the machine, is a lever 56 having fulcrum arms 5'? thereon and having at its forward end a finger key or bar 58. The rear end of the lever is pivotally connected to lift rod 59, the upper end of which bears against a rockable arm 51. Arm 6! is fastened to sleeve 82 pivoted on shaft 63, the latter being suitably supported in gear housing HS and back plate 6 of the housing.

Formed on the opposite end of sleeve 52 is arm to which is pivoted a link 66 having a pivotal connection with a plate El rockable on stud 58. Connected to plate 5'? by means of sleeve 69 is a second plate ll having spring clips T3 thereon for supporting a mercury switch $3. This switch is in series with switch 35, a1 suming the latter switch to be closed, is adapted to control the motor through suitable wired connections (not shown), so that, when the plate is tilted in one direction, it will start the motor, and, when tilted in the opposite direction, will break the connections thereto to stop the motor.

On the back of gear 53 there is formed or s cured thereto a cam piece 14 having a depression therein. Pin E6 on plate 6'1 is adapted to fall into depression 15 when the switch is tilted to the position shown in Fig. 5, which is the normal cut-out position of the switch. When finger bar 53 is momentarily depressed, plate is tilted through lift rod 59, arms 8!, 5 and link to throw the switch into circuit-closing position. At the same time, pin 76 is elevated to a position wherein it will ride on the periphery of cam piece '54. The switch is, therefore, held in circuitclosing position until gear 53 has made a substantially complete revolution, when pin '15 drops into depression l5, positively tilting the switch to its circuit-breaking position, being aided by contraction of spring .l' attached thereto. Pin "it! on cam piece 74 engages a projection 88 on plate Bl at this time and prevents further revolution of gear 53. At the same time, the motor is stopped. It will be seen that, when plate 8? is again tilted, pin 1'8 clears projection 89 and permits rotation of the cam.

When spring 2''! tilts the plates 6! and 7!, link arms 6!, and lift rod 59 will be forced downwardly. Referring to Fig. 2, it will be seen that there is loosely mounted on shaft 35 an arm 13 having a slot 79 at its end engaging a pin 8i on lift rod 59. Arm 73 carries a pin 32 which, when finger key 58 is released. engages the projecting end 83 of pawl 38 and holds the pawl out of engagement with ratchet 3?. When the finger bar is depressed and lift rod 59 elevated, pin 82 rides over the projecting end of the pawl to re lease the same and permit spring 4! to pull the pawl into engaging position with the ratchet. Since the elevation of the lift rod closes switch 13, thereby starting the motor, it is apparent that pawl 88 and ratchet 3'! act as clutch to rotate bevel gear 43. and start the gear train into operation.

As soon as pin 16 drops into depression l5, however, the lift rod will drop to a position in which pin 82 lies in the path of the projecting end 83 of pawl 38 and releases the pawl from the ratchet teeth, assuming the finger bar has also been released. This occurs after the gear 53 has made one revolution, and, even though the motor may overrun, it is apparent that the clutch is not operable to form a connection between the motor and the gearing.

As stated hereinbefore, housing !9 encloses metering mechanism indicated generally at 8 and the die 22 bearing postage printing members. It is to be understood that the housing is, together with the meter and printing die, are removable from the machine, and when it is desired to attach the same thereto, the housing is slid down vertically between flanges IT on housing IS, a suitable shaft and drive connection heing provided between shaft 54 and the printing die shaft. t is now apparent that, upon rotation of gearing 43, 45, 47, 52 and 53, the die members will be rotated. The die itselfcomprises a cylindrical member 1'2 having number of projecting faces 84 on its periphery and mounted eccentrically with respect to its carrier. Suitable mechanism, forming no part of the present invention, is provided to operate the postage registering mechanism used in accordance with the die setting.

The die may be changed to present the particular denomination desired by means of a shaft 85 having a knob 86 detachably secured thereto by means of a set screw or other suitable securing means 81. The end of shaft 85 is provided with a flat portion 88 to insure rotation thereof when the knob is turned. Shaft 85 can be rotated only when it is sli htly withdrawn, the reason for this being that the inner end of shaft 85 is reduced and enters holes in the end of die carrier 89. When the end of the shaft is in engagement with these holes, it holds the die in set position.

The dies 84 project through an opening 9| in the die carrier. Spaced from opening 9! is a second opening 92 through which a ring die 93 projects. This die is held in position by screws or other sutable means, but is removable if it is desired to change the ring die. t is to be understood that the ring die is one which makes a circular impression on the mail matter and usually bears the post oflice designation and date thereon. The date die comprises the customary rotatable printing wheels, and access thereto may be had through opening 95 having a cover plate 95 pivoted to housing 2!.

The die carrier is suitably geared to the counting mechanism through gears 97, 98, geared respectively to counting mechanisms HH and M2. The former of these counting mechanisms is of the ascending type, while latter is of the descending type. Counting mechanism If)! indicates the total postage used over a period. while the counters I02 are adapted to be set for a prepaid amount of postage, and, as the postage is used, the number indicated decreases. counting mechanisms will not be described in detail, because they are of the usual type employed in registers.

Visual indications of the total postage consumed and that remaining to be used may be obtained through transparent pieces in the top plate m3 of the meter housing and a slidable plate I04, respectively. Plate Hi lis provided with a depending flange Hi5 having a lock I95 thereon by which the same may be locked to the side of meter housing l9. This lock can be opened only by a properly authorized representative of the Government, who withdraws the plate 104 to obtain access to the descending counting wheels and resets them in accordance with the amount of postage paid for. Lugs I87, I08 are provided with perforations through which wire is passed and a lead seal attached by the postmaster to prevent fraudulent unlocking of plate 264.

Associated with the descending countin wheels is a lock mechanism similar to that shown in the patent to Mitchell and Zahn. No. 1,659,213, dated February 14, 1928. and. comprising a bar 559 extending through the meter frame and through a slot in shaft H2. In each of several These of the counting wheels, in the present instance in three wheels, there is provided a radial slot on the inner periphery of the wheel. These slots are so positioned that, when the zero figure on each of the wheels is in alignment with the observation window, th slots will be disposed immediately beneath bar I09. Spring H3 normally tends to pull the bar into the slots and will do so when the wheels move to indicate that postage amounting to less than one dollar ($1.00) remains to be used, thus locking the machine against further use.

In some instances it is desirable to make more than one impression of a denomination on a piece of mailing matter. In order that these several impressions be made with but a single impression of the ring die or post office designation, the means now to be described are provided.

Projecting through a segmental slot H4 in the frame I5 is a knob H5 having an indicator H5 thereon. As will be noted in Fig. 1, there is indicated'on the face of the frame at I H the position in which the knob should be when it is desired to make a single postage imprint and the ring impression, well as the position the knob should occupy when it is desired to print postage without the ring die impression. Knob H5 is fastened to a lever H8 pivoted at H9 to bracket I2I, the latter bein secured on the under side of frame I5. The opposite end of the lever is formed with a slot I22 which cooperates with pin I23 fastened to shaft I24 and mounted for reciprocation in guides I25, I26 on bracket I2! Fixed to shaft 524 is a lever I2! having a segmental rack 94 at one end thereof meshing with pinion I28 fastened to shaft H29. To the other end of shaft there is secured an arm IiiI to which is pivotally connected a link 532. This link passes through bore I33 in block I54, the end of the link being threaded to receive nuts I35, I36. Surrounding the link is a relatively strong spring I31, the compression of which may be adjusted by turning nuts I35, I36. Pivoted to block I34 are a pair of toggle links I38, 39. Movement of arm I3I is transmitted through the spring to straighten the toggle, but, after the toggle is straightened as much as is necessary, link I32 can move further due to the lost motion connection with the toggle. Link I38 is pivoted at I4I to a depending portion of the frame, while link I 39is pivotally connected to arm I42 mounted for oscillation on shaft I43. Arm I42 carries sleeve 5| and shaft I44, on which impression roll I45 of rubber or other fiiiction material is mounted. Lever I21 carries at one end thereof a roller or cam follower I46 adapted to follow either cam I4l or cam $43, depending on the position of lever I2! as de termined by the position of knob IE5. In other words, as shown in Figs. 1 and 3, shaft I24 and lever IZ'I are moved to the extreme right position (Fig. 3) so that roller M5 cooperates with cam I43. As will be seen in Fig. the high surface of this cam is considerably longer thanthat of cam I41 and will depress the roller 546 for a relatively longer period. When the cam follower is depressed, the segmental rack 94 on the opposite end of the lever will rotate pinion I28 and move arm 53! to the left in Fig. 5, whereupon arm I42 will be elevated, raising impression roll I45 to hold mail matter against the die sufficiently long to causenot only the postage value but the ring die as well to be impressed on the matter.

On the other hand, when knob H5 is moved to the position designated in Fig. l as Multi, the cam follower is moved to the left in Fig. 3 to cooperate with cam Ml. This cam will elevate impression roll I45 for a period long enough to print the postage value only, the roll being dropped before the ring die has come to the position in which it would print the post office designation on the mail matter. It is to be noted that sleeve 5I carries a pinion I45 meshing with pinion I5I, the latter being secured to roll M5.

The impressions made by the dies on mail matter must be very clear. If the impression roller exerts too little pressure on the under side of the envelope, the printed stamp will be light, while too great a pressure results in a smudged impression. The adjustable connection between link I32 and the toggle I38, I39, wherein the compression of spring I3! determines to a fine degree the clearness of the impression, permits printing of the character desired by the Government. At the same time, the lost motion connection between the link and toggle enables the impression roller to adjust itself to varying thicknesses of the mail matter passing the printing dies.

Since careless or unauthorized operation of the machine may occur when the attendant is not present, means are provided for locking switch plate tI so as to prevent tilting of the mercury switch. These means comprise a pin I52 on the switch plate adapted to be engaged by a hook 53 on lever I54 pivoted at I55 on the back plate I54 of the gear housing. Spring I 56 tends to hold the lever in a position wherein the hook engages pin I52. The hook is released by inserting a key in look I5! in the back of the gear housing and turning a cam piece I58, the latter engaging lever I54 to move said lever to the dotted line position indicated in Fig. 6. Thus the operation of the machine may be controlled by a key in look I51 in the back of the gear housing, so that, by turning the key, plate 'Il may be locked or released for oscillation. Usually the operator will remove the key from the machine when not in use, the hook then engaging the tiltable switch plate. Incidentally, due to the connections of the switch plate with finger bar 58, the bar is also prevented from being depressed.

After the counting wheels have been set by the postmaster or other authorized government official, the meter is attached to the machine and operating mechanism by sliding the back plate downwardly to connect the gearing with the die carrier and registering mechanism. Bolt I59, having a key head insertible in a suitable opening in the meter housing, is then drawn taut by tightening nut I6I. Switch is then closed and, after knob 86 has been turned to bring the desired postage die to operating position, the machine may be operated by pressing finger bar 58 to tilt mercury switch I3 to closed position. When bar 55 is depressed, pawl 38 and ratchet 31 engage to rotate gears 43, 45, etc., whereby impression roll I 45 presses the mail matter against the rotating die 23 corresponding to the value for which the knob is set.

As the die cylinder rotates, the meter registers postage corresponding with value at which knob 86 is set. The descending counting mechanism will continue to register until bar I09 is permitted 2 bolt, the head of which is indicated at I64.

to drop into the aligned slots in the counter wheels, whereupon further rotation of the printing die is prevented. As previously explained, the machine may be set either to print postage with the post oflice designation, or a combined mark comprising the postage and post mark. In one instance, feed roll I45 holds the mail matter against the opening I62 on the under side of housing 2! only long enough to permit the postage to be printed on the mail matter. In the other position of the knob H5, the roll holds the mail matter against the die cylnider for a longer period, so that not only the postage but the post mark as well is printed on the mail matter.

When knob H5 is set to the position in which a single stamp impression and post mark is made, the impression roll and printing member will carry an envelope through the machine at a fairly rapid rate. Ordinarily, the envelope will be thrown forward sufiiciently to clear the impression roll. It is apparent that, when the knob is set to multi position, it is not desirable to impart a kick to the envelope for the reason that the stamp impressions would be too far spaced, whereas it is necessary that they be contiguous to each other. A retarding means in the form of spring 32 is, therefore, provided. As hereinbefore stated, the degree of retardation may be varied by turning the knurled head 33' 0f threaded bolt 33 s that, depending on the type of mail matter being stamped, the proper resistance to obtain accurately spaced successive stamp impressions is provided.

For som operations it is desirable to render spring 32 entirely ineffective. In order that pressure may be readily and quickly removed from the spring, bolt 33 is threaded in a swiveled block it? pivotally secured to bracket 29 by means of a The adjusting piece can thus be swung to a substantially horizontal position out of contact with spring 32, the latter member straightening more or less when relieved of pressure. Parcel post strips and other matter requiring special attachments having their own retarders make the use of spring 32 unnecessary.

The machine is compact, and, when it is assembled, the fastening devices, such as screws, etc, are of a character which prevent disassembling of the meter housing and postage setting mechanism so that fraudulent operation of the machine is impossible. The meter housing, when removed from the machine, occupies very little space and can be conveniently carried to the post oihce or other government oflice. A handle [65 is provided for this purpose.
