7 Claims.

This invention relates to a value printing and registering machine and more particularly to the mechanism for setting the value type wheels and register actuating mechanism.

In value printing machines such as metered mailing machines, having means for the printing of omni values, the value type wheels are adapted to be set by means of setting levers. Each setting lever is adapted to adjust a type wheel associated therewith, and is further adapted to efiect control of the setting of a register actuator.

In the present invention it is the principal object to provide means whereby, the setting lever of highest order is adapted to be adjusted to a point beyond that which is normally provided in the setting of the digits through 9 to thereby effect the setting of a value greater than the 9 value, and further to adjust register actuator means in such manner as to effect the registration of the said greater value during a machine cycle of operation.

It is another object of the invention to provide means whereby the additional setting of the setting lever of highest order is made possible only when the setting levers of lower order are in their 0 positions to thereby prevent misregistration in the actuation of the value registering mechanism,

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 drawings, where- Fig. 1 is a side elevational view, with parts broken away and parts in section, showing the setting levers in their 0 positions and includes connections with the type wheels and totalizer actuating gears;

Fig. 2 is a plan view of Fig. 1;

Fig. 4 is a front elevational view of a postage meter unit, with parts broken away, showing a portion of a delayed transfer totalizer and actuator;

Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 1; and

Fig. 6 is a detailed elevational view showing gearing and rack connections to a type wheel of highest order,

Referring to the drawings in detail, a rotary printing drum It! has four type wheels mounted therein, designated by the reierence'character l l for a 12$ type wheel, l2 for a units type wheel, l3 for a tens type Wheel, and H! for a hundreds type wheel. Fixed to each of the type wheels are pinions designated as Ila, l2a, l3a and Me, which are associated with the type wheels ll, l2, l3 and M respectively. Said type wheels and pinions are further mounted upon a stud l5 supported within the printing drum l9 and are normally in a horizontal position when the drum is in its home position.

The pinions Ila, l2a, l3a and l lo are connected with a series of racks llr, l2r, l3r and Mr respectively, there beingalso suitable intermediate gearing llg, 12g, Hg and Mg between said pinions and racks respectively. The rack portions form a part of rack bars llb, 12b, I31) and Mb respectively, which extend into the meter unit where they are arranged for connection with setting levers l6, ll, and l8. The setting lever I8 is associated with the rack bar lib, the setting lever H is associated with the rack bar I21), and the setting lever I3 is associated with the combined rack bars l3?) and I412.

The setting levers are pivotally mounted as at 2| and each is adapted to control a variable toothed or mutilated gear member when setting of the type Wheels is effected. As best shown in Fig. 1, each setting lever includes a forwardly disposed rack segment 22 and a notched detent rack 23, the latter being provided on a rearwardly disposed wing 24.

A variable toothed gear 25 is connected with the setting lever of highest order l8 in such manner that it may be adjusted longitudinally during a type wheel setting operation. Said variable toothed gear is also rotated with the printing drum 10 during a printing operation to effect actuation of a totalizer unit in a manner to be later described. The variable toothed gear 25 is secured to a hollow shaft 26 by means of a pin 21, which pin passes therethrough, and is slidable within longitudinal slots 2la-2'la in the shaft. Upon rotation of said shaft 26, which may be provided by any suitable means, the variable toothed gear 25 will be driven. The pin 21 is further connected with two of the rack members I32) and Nb, which are associated with the type wheels 13 and M of the tens and hundreds order respectively. Any longitudinal movement therefore, of the variable toothed gear 25, will also effect movement of the rack bars I31) and Mb and thereby cause adjustment of the type wheels 13 and I4.

Adjustment of the variable toothed gear 25 is provided by means of a yoke member 28 which rocks with the setting lever l8 about the pivot 2|, and which has pins 29-29 projecting therefrom which engage a slot 3| in a flange 30 at one end of the variable toothed gear.

The two setting levers I6 and l! are connected with variable toothed gears 32-43 respectively in a manner similar to that described for the setting lever [8, the only difference being that each is connected with a single rack bar I lb and I2b respectively instead of two rack bars. Fur ther description of the structure of said latter variable toothed gears 32 and 33 is not deemed necessary because the invention is more directly associated with the setting lever of highest order which in this disclosure is the tens setting lever l8. It may be stated here however, that the rack bars [lb and [2b, which are associated with the setting levers of lower order I6 and [1, have slots 3435, therein respectively through which the pin 21 of the variable toothed gear 25 extends. By means of said slots 3435, clearance is provided for either the adjustment of the variable toothed gear 25 or the individual adjustment of the rack bars Ilb or l2b.

The elements of particular importance are those which are associated with the setting of the type wheel of highest order to a value which is greater than that normally settable. In this particular disclosure it involves the setting of four type wheels by means of three setting levers. The setting of the fourth type wheel is effected by means of the third setting lever l8, and is accomplished by providing means whereby the said setting lever I8 is permitted to move one step beyond the setting lever of next lower order, thus moving the type wheel associated therewith from a 9 to a position, and by means of a connection now to be described, moving the fourth or hundreds type wheel M to a 1 position.

When moving the setting lever H! from the 0 to the 9 position, both rack bars I31) and Mb are moved simultaneously, but only the rack I31 is effective in rotating its associated type wheel l3. As viewed from Fig. 6, the rack bar Mb, which is associated with the hundreds type wheel M, has a rack I M consisting of only two teeth, which are positioned so as to engage a pinion [4g at the time the tens'type wheel is moved from the 9 to a 0 position. Forwardly of the teeth, the rack bar Mr is further provided with one flat edge 20 which is adapted to engage with the ends of three teeth of the said pinion Ma, which teeth have their ends cut back to thus permit same to become locked against the edge 20. In this manner the flat edge 20 will move across the pinion teeth as the rack I 4b is moved, through the adjustment of the setting lever I8. The pinion Ma will thus remain immovable until the two teeth of the rack portion Mr become engaged therewith. Hence, the hundreds type wheel is normally locked during the setting of each of the other type wheels during their normal setting from 0" through the 9 positions, or during the setting of the half cent type wheel from the 0 to the position.

Before making an adjustment of the hundreds type wheel to the 1 position, it is important that each of the setting levers of lower order, including the type wheels associated therewith, be in a zero position. It may be well to state here that owing to the fact that only three variable toothed gear members are provided, one for the half cent order, one for the units order, and one for the tens order, a totalizer mechanism which is indicated generally at T, will normally be adapted to register the total resulting from the highest denomination on each of said variable toothed gears, which would be nine teeth on each of the tens and units gears and the onehalf value on the one-half cent variable toothed gear, providing the sum total of 99 42. Any value higher than the 99%;!3 if desired, would require another variable toothed gear. But, according to the arrangement of the present structure, it is possible to raise this total value by in cluding another tooth on the variable toothed gear of highest order, thus making a total of ten teeth. Before the tenth tooth portion of said gear is permitted to be adjusted to the latter position however, the units or one-half cent type wheels and related variable toothed gears must be in their 0 positions. If the latter type wheels were not in their 0 positions the variable toothed gears of lower order would actuate the'totalizers, and if a transfer should occur between the tens and hundreds totalizer a misregister of the totalizer mechanism would occur.

Provision is therefore made to prevent the setting of the tens setting lever l8 to the last position arranged therefor, until each of the setting levers of lower order are in their 0 positions. Said provision comprises the notching of the underside of the wing portion 24 of each of the levers of lower order, as indicated at 38, and mounting a bail 39 in such manner that one edge 4| thereof will be adapted to move freely into the notched portions 38 when the setting levers of lower order are in their zero positions. To accomplish this, the bail 39 is pivotally mounted in bearings 42-42, as best shown in Fig. 5, and has one forwardly projecting lip 43, which is normally urged against the underside of the setting lever of highest order 3, by means of a spring 44.

On the lower edge of the wing 24 of the tens setting lever I8, is a cam lug 45, which lug is adapted to engage the lip 43 when the said tens setting lever is advanced to its final setting position, that is, from the 9 to the 10 position. Said movement to the last position is permitted only when the notches 38 in the wing portions of the two setting levers of lower order are opposite the bail edge 4|, and this only occurs when the two setting levers of lower order are in their 0 positions. If either of the setting levers of lower order is not in a 0" position,

and it is intended to move the setting lever of highest order from the 9 to 10 position, the

edge 4| of the bail 39 will become jammed against the lower surface of the wing and thereby prevent movement of the setting lever of highest order.

During the setting of the setting levers, the rack segment portions 22 of each segment are adapted to set indicator wheels I610, H10 and I810, which wheels are mounted on a shaft 41 and agree with the setting levers l6, I1 and I8 respectively. Pinions. 16p, Hp and Hip are also associated with each of the indicator wheels respectively and mesh directly with the rack portions of the rack segments 22.

Normally, the said indicator wheels would be adapted to register the total value of 99 /2, but with the addition of the extra movement of the tens lever it is possible to set up a dollar value. To provide for the indication of said dollar value, a one-dollar indicator plate 45 is mounted upon a U-shaped support 50, which support is pivotally mounted upon the indicator wheel supporting shaft 41 and is normally urged toward a stop 49 by means of a spring 48. One leg of the U-shaped portion of the indicator lies adjacent the tens indicator wheel lBw, and when the said wheel is rotated from the 9 to the next higher or position, a pin 5|, projecting from the side of said tens wheel and in the path of the said leg, will engage with the leg and move the indicator 46 to the indicating position of Fig. 3.

The registering mechanism or totalizer which is of the delayed transfer type is best shown in Fig. 4 and generally comprises an ascending totalizer indicated at A and a descending totalizer indicated at D. Each of the totalizers includes transmission gears 52, which are adapted to be engaged by the variable toothed gears 25, 32 or 33, and are thereby rotated in accordance with the number of teeth which agree with the value printed. As is common in totalizing mechanisms of this character, at the time the transmission gears are actuated by the variable toothed gears, and cause associated indicator Wheels 54-54 to be moved beyond a 9 position, transfer members, such as indicated at 53, will be pre-set for a transfer operation. Then through a later part of the cycle, the transfer is completed between a register wheel of lower and a wheel of higher order. A complete description of the registering mechanism may be found in co-pending application Serial No. 374,076, now Patent Number 2,306,500, issued December 29, 1942.

In the operation of the device, the mechanism for preventing misregistration, which is particularly pertinent to the features claimed, will now be described by way of a specific example.

Assuming that the reading on the register is as follows:

TH H T U 0 9 .9 9 /2 and that the amount $1.09 /2 is to be added, the several steps of operation are as follows:

TH H T H /2 A 1 0 .0 9 0 Condition of register after effecting transfer X 1 l 1 Transfer as set from wheel of lower order B 0 9 .9 8 0 Condition of register after entry C 0 9 .9 9 /2 Number standing in register A D 10 9 Number to be entered To clearly understand the problem, the value (109 /2) which is to be entered must first be properly separated as in row D, i. e. (10-9- /2). As shown above, the /2 value is entered in the /2 column and the units value 9 is in the units column. But the tens and hundreds values 1 and 0 are entered as 10 in the tens column, because the tens mutilated gear 25 has ten teeth instead of the usual nine. Hence, the tens register wheel will be rotated a full revolution, and will always effect a transfer setting operation.

direct addition to the digits /2, 9 and 10 of row D in the order named to the number standin in the register (09.99%) will result in the reading 09.980 of row B and transfers will be set for entry into the units, tens and hundreds values in the manner indicated in row X. For instance, the value /2 of row D when added to the value /2 of row C will provide a 0 in row 13, and a transfer setting for entry in the units column; the units value 9 of row D when added to the value 9 row C will provide an 8 in row B, and a transfer setting for entry in the tens column; and finally the tens value 10 of row D when added to the value 9 row C will provide a 9 in row B, and a transfer setting for entry in the hundreds column. Following the setting of the transfers, said transfers are added to the col umns of row B, first the units column 8 and l to obtain 9; then the tens column 9 and 1 to obtain 0, but an additional transfer setting which should occur here is lost because there had previously been a transfer setting when the value 10 was entered, and two transfers in one value wheel during a single cycle of operation cannot be effected in any tens register mechanism. Hence, the reading in the hundreds column remains at 0 instead of l, and after the final transfer from the hundreds to the thousands column, the total value reading will be 10.090 instead of 11.090, an obvious misregister.

By way of the above example, it will be seen that the provision of means to prevent the setting of the setting lever of highest order to its final setting position until all levers of lower order are in their 0 positions, is the solution of a problem, which if not provided would result in misregistration of the registering or totalizer mechanism.
