In Norway January 10, 1935 4 Claims. (01. 101-91) The present invention has for its object improvements in value stamping machines such as postage stamp cancelling machines, cash registers, ticket printing and amount counting machines or the like, use beingmade of toothed drums or segments with step-wise arranged teeth co-operating with the respective wheels in an automatic counting device (hereinafter termed "counter). The invention is distinguished substantially by the fact that the type wheels serving to stamp or print the value (for instance upon a letter, ticket or the like) are rotatably arranged in a member which is in turn mounted rotatably in the machine, the mechanism for adjusting the type wheels being'so arranged that the same, simultaneously with the type Wheel setting, provides for the corresponding setting of the toothed drums opposite their appertaining wheels co-opcrating with the counter.

% The invention is further distinguished by the fact that the setting of the parts for the respective values takes place by means of a mechanism which is-driven by the machine and is so constructed that its operation may be controlled by means of the depressible keys.

By the said arrangements it is possible to produce a value stamping machine which is particularly simple in construction and is easy and safe in use, the whole setting consisting only in pressing down the key or keys corresponding to the desired values.

An embodiment of the invention is iilustrated in the annexed drawings. Figs. la and 11) when taken together show by way of example a postage stamp cancelling machine in front view partly broken away and with the cap or casing in longitudinal section. Fig. 2 shows a machine in plan view, the cap being removed. Fig. 3 shows a cross section on the line III-III of Fig. 2. Fig. 4 shows in plan view a position of the setting mechanism.

Fig. 5 shows the same in front view partly in section. Fig. 6 is a portion of Fig. 2 and shows a modification for manual setting.

In the drawings the base i of the machine can ries bearings 2 and 3 for a rotatable shaft 4. At

one end of the shaft 4 a printing head 5 is fastened, wherein the type wheels 6 serving to stamp the value are journalled rotatably on a pin I. To each of the type wheels 6 a toothed wheel 8 is attached which meshes with a rack 9 which is displaceable in the axial direction of the head and by its displacement rotates the gear wheel 8, whereby simultaneously the type wheel 6 fastened thereto is turned for setting.

On the shaft 4 four toothed drums iii are displaceably but non-turnably mounted and provided as shown with nine step-wise arranged rows of teeth ll serving to operate a gear wheel I! which in turn serves to drive the item wheel oi the counter T appertaining to the respective toothed drums.

The racks 9 serving to set thetype wheels are extended in the axial direction of the. shaft 4 and are attached each to one toothed drum III in such a relation that, when each drum I0 is displaced for co-operating with the wheel II, the corresponding type wheel 8 is set to the value which corresponds to the number of teeth entering in operation on the gear wheel l2.

Each of the toothed drums M has an annular groove I3 receiving a roller or pin ll of a setting arm l5 swingabie in the horizontal plane and having the end which is located behind the shaft 4 fastened turnably about a screw Hi, the front end of said arm resting upon a carrying member II which extends in the longitudinal direction of the machine as shown.

By now swinging the free ends of the arms ll through a greater or less angle to the right (Fig. 2) from the zero position shown in the drawings, the respective toothed drums It may be brought into such a position in relation to their appertaining wheels i2 that any number or the teeth II will be positioned to operate the said wheel i2 during rotations of the shaft 4, and simultaneously the respective type wheel 6 is so turned that the item corresponding to the number of operating teeth of the drum Ill is set in printing position in the head 5.

In order to set the arms l5 mechanically in the desired positions and thereby to set type wheels to the desired values, a bar i8 is arranged in the longitudinal direction of the machine above the free ends of the arms It, said bar it being displaceable in its longitudinal direction and being provided at the right hand end (Fig. 2) with pins or rolls i9, between which the upper end of an arm 20 projects, the lower end of which is mounted turnably on a shaft 2|. At some height above its axis the arm 20 is provided with a roll 22 projecting into a cam groove 23 on a cam disk 24 fastened to the shaft 4.

0n the underside of the bar II and in front of the arms I! pins 25 are arranged which during the movement of the bar I 8 to the left (Fig. 2) serve to swing the arms into zero position. Further, for each arm ii there is tiltingly attached to the bar II a hook it projecting through a slot l8a in the bar ll behind the arm l5, said hook being pressed down by a spring 21 and serving to move the arm II to the right during the setting movement of the bar II.

In order to stop the arms II during setting and thereby also to stop the drums II in the desired settings in relation to the operating wheels ll of the counters, vertically movable pins 28 are arranged in the carrying member IT, a group of ten pins being provided for each of the arms ll. Each group co-operates with one of four rails II, which are retained displaceably in longitudinal horizontal slots in the carrying member I! as shown, said rails being provided with teeth II which may co-operate with notches II in the pins 28 and are adapted to retain the same in an elevated position, the rails being acted upon by springs 82 which always tend to press the teeth II of the rails against the pins 28.

The first one of the pins in each group, the pin 28', is connected by a Bowden-wire transmission with a member which '1 acted upon by an eccentric attached to the shaft 4 immediately before the shaft 4, after having completed one revolution, comes into the zero position, so that the pin 28' in the resting or zero position of the machine is always lifted and held fast by the appertaining tooth on the rail 28, whereby its upper end locks for the movement of the appertaining arm I to the right.

In its lifted position the pin 28' will act upon an arm 26' attached to the appertaining hook I, so that the hook it is retained so much elevated that it cannot act upon and take along with it the appertaining setting arm iii, when the bar I. is moved to the right. The arm 26' of the hook 26 has an inclined face 28" which during the movement of the bar It will act to lift the latter, when the arm 26' strikes against a lifted pin II. The other pins in each group are connected by Bowden-wire transmission each with its depressible key at the front side of the machine, said keys being in usual manner grouped in relation to and provided with indication of the setting value corresponding to the same.

On the end of the shaft 4 is turnably Journalled a coupling member 36 which co-operates with a coupling member 30 carried by a handle or the line 31.

The machine described above operates, when used, in the following manner:-

In the position shown in the drawings of the respective parts, which are seen in resting or zero position, all the pins 28' and also all hooks 28 are in lifted position. It therefore the machine is started by coupling together the coupling members 38, 38, so that the shaft 4 is caused to rotate in counter-clockwise direction in Fig. 3, the bar II, by means of the roll 22, is at once moved to the right. However, during this movement the hooks 26, because they are retained in lifted position by the pins ll are held out of engagement with and pass by the arms I5, so that the latter are not taken along, and therefore no setting will take place. When the shaft 4 approaches its initial position, the bar I8 is again moved to the left into its initial position shown in the drawings.

when a value stamping is to take place, the key It corresponding thereto is depressed, whereby the appertaining pin 2| is lifted into locking position, wherein it is retained by the appertaining raiill, whose tooth ll projects into the notch ll of the raised pin 28. Simultaneously with the 1mm; of the pin a, the appertaining rail 2: is

displaced to the left against the action of the spring 32. due to its co-action with the inclined surface of the notch 3| so that the pin 28' of the group to which the lifted pin 2| belongs, is released by the rail 29 and falls down, whereby the hook I! is released and projects down hehind the setting arm II.

When the machine is now started and the bar II, as described above, is moved to the right, the arm I5 and consequently the toothed drum ill of the group to which the lifted pin 28 belongs are taken along by the hook it, until the arm 28' of the latter strikes with its inclined face 26" against the lifted pin 28 and thereby is lifted upwarda' Thus the hook 26 is disengaged from the arm i5, and the latter comes to rest in engagement with the pin 28, whereas the bar |l continues its movement to the right, until it reaches is extreme position. When this is reached, the type wheel 6 and the drum II have been moved into the position corresponding to the desired value, whereafter the stamping and the operation of the counter take place.

During the last part of the revolution of the shaft 4 the cam groove 23 of the disk 24 causes the bar I! to be moved again back into initial position. During this movement the hook 25, on account of its inclined rear surface 26a rides over and behind the arm l5, whereupon the latter and consequently the drum |U are taken along by the pin 25 and carried back into initial position. Immediately before the shaft 4 has completed its revolution, the said eccentric mechanism will also act upon the first-named pin II of the group and will lift the same, whereby the rail 29 is moved to the left, so that the set pin 28 falls down again into in-operative position, whereas the pin 28' again lifts the hook 26 and retains same in in-operatlve position. All the parts now have the initial or zero position shown in the drawings, and the stamping may again take place in the manner described above.

If a series of stampings of the same 'value is to be effected, the functions described above must be repeated at each revolution of the shaft 4, but in order to avoid unnecessary movement of the bar i8a repeating mechanism is arranged by means of which the set value may be maintained during a desired number of stampings.

The arm 20 which serves to move the bar II is rotatably mounted on the shaft 2|, which is in turn displaceable in its longitudinal direction in a carrying member 39 and the casing 40, its inner end being carried by a slide 4| which may be displaced in the longitudinal direction of the shaft 2|. The slide 4| is normally retained in its inner position by means of a spring 42. On the shaft 2! an arm 43 is displaceably but nonrotatably arranged, the said arm having a forked end 43a adapted to embrace the arm 20. The said arm 43 is prevented from being displaced together with the shaft 2| in its longitudinal direction by means of a U-shaped guiding member 44 (Fig. 2). The carrying member 39 is provided with a hub 45 having spaced diametrically arranged grooves 46 and 41 which have different depths, considered in the axial direction of the shaft 2|, said grooves serving to receive a transverse pin 48 arranged in the shaft 2|, the groove 48 with the largest depth receiving the pin 4|, when the parts are in the normal position shown in the drawings.

If a series of stampings of equal value are to be effected, this value is set by the depressing of the proper key or keys II. Thereafter the shaft II, by means of a handle 48 attached on its extreme end, is pulled outwards in its axial direction against the influence of the springs 42 and during this movement the pin 48 is moved out from the groove 46 in the hub 45.

Simultaneously the arm 20 is taken along, and engaged in the forked end of the arm-43, the roller 22 being thus moved out of engagement with the cam groove 23 in the disk 24. when then the shaft 2| is turned clockwise, Fig. 1, by means of the handle 49 the arm 43 will swing the arm 20 to the right, so that the bar II which is taken along performs its setting movement and during this movement, as described above, causes the setting of the drum l0 and appertaining type wheels 6, whereafter the pin 48 in the shaft 2| is moved into the groove 41 which has such a depth that the shaft 2| and consequently the pin 22 are retained in inoperative position with respect to the cam groove 23.

The shaft 4 can now be caused to rotate for effecting any number of stampings, without any alteration taking place in the set value, because the setting mechanism has been released from the machine in the set position. When the last stamping has been effected, the shaft 2| is moved back, until the pin 48 again falls into the groove 46, and during this operation flrstly the arm 20 and consequently the bar I8 are moved back into the initial position, the arms l5 and the toothed drums ll being thereby carried back into zero position as described above, whereupon the shaft 2| is moved axially by the spring 42, so that the arm 20 is moved out from the forked end of the arm 43 and the roller 22 is again moved into engagement with the groove 23 in the disk 24. All parts have'now been restored to normal position, in which ordinary stamping may take place in the manner first described.

As will be understood the detailed construction may be varied in several manners without departing from the scope of the invention. Thus between the type wheels and the toothed drums an indirect connection may be arranged, and a regulation may be effected by acting upon this connection.

The setting may also take place by direct movement of the setting arms I! manually by external means for setting the drums axially independently of each other, for instance as indicated in Fig. 6. According thereto each arm I! is provided with a handle I, and projections 50, preferably spring-pressed, are arranged on the top side of member H to arrest the arms I! in their several adjusted positions.
