This invention relates to a machine for producingstamped impressions or marks of v the kind wherein a rotary printing member has in a peripheral aperture a currenc 5 value stamp comprising individually ad ustable types representing numbers, and a rotary counting device outside it.

According to the invention a set of cams is provided on the periphery of the said printing member for transmitting at each revolution of the latter the value set thereon to the counting mechanism, which cams are operatively connected each with a setting member for each lace value to be set, and at each revolution 0 the printing member shift, corresponding to the magnitude of the value in question, each a toothed rack arranged to drive a numeral disc of the counter in only one direction, the transference of the tens from one numeral disc to the next being efi'ccted separately by means of an auxiliary or second feed device controlled by the printing member.

When the rotary printing member is formed as a hollow cylinder containing rods or bars which extend lengthwise therein and carry numeral types displaceable in their longitudinal and transverse direction, each place value of each of which types can be set in the said aperture of the printing cylinder, according to a feature of the invention the setting members for the types of each place value are slides movable along the said bars, which slides when being moved coact each with a lever which is operatively connected by a transverse slide extending through the wall of the cylinder with one of a plurality of cams arranged adj ustably on the periphery of the printing cylinder, so that by shifting the first-mentioned longitudinally movable slides the lift of the cams is varied corresponding to the magnitude of the displacement of the latter slides.

According to another feature of the inven- 4-i tion toothed racks serving for rotating the numbered discs of the counters are controlled in such a manner by the printing cylinder by means of levers, that during one revolution of the cylinder they are (a) engaged twice with the counter discs for causing the 332,O83,-and in Switzerland January 16, 1928.

latter to be rotated by the said came on the cylinder and for subsequently transferring the tens by means ofother cams of the cylinder, and (b) disengaged twice therefrom for permitting them to return into their initial position.

According to a further feature of the invention, the toothed racks have longitudinal slots, in each of which engages one arm of an angle lever actuated by a cam on the printing cylinder, the other arm of which lever so controls a locking'device of the allotted counter disc that, when the toothed rack is disengaged, the said disc is held against rotation and, when the rack is engaged, is released.

According to yet another feature of the invention it is arranged that for subsequently transferring the tens from one counter disc to the next, the counter discs are so set at each revolution by a setting pawl or tumbler that is operatively connected with the toothed rack of the next disc, in relation to a lever that is controlled by the printing cylinder and serves to actuate said rack, that the latter is shifted one tooth by the said lever by means of the setting pawl or tumbler, whereby the feed of the following discs takes place in succession.

One embodiment of the invention is diagrammatically illustrated by way of example in the accompanying drawing, wherein Figure 1 is a longitudinal section through a machine according to the invention.

Like reference characters designate like parts throughout the several views.

Referring to the drawing, a horizontal hollow printing cylinder 2 is journaled on a base portion 1 of the casing by means of a stub axle 3 in a bearing 4 at one end and an annulus 5 at the other. So many pairs of rods or bars 8 have their rear ends pivoted one beside another on an axle 7 common to them all mounted in the (rear) end wall 6 of the cylinder 2 as the hereinafter described value stamp has place values, namely in the present example live. The pairs of bars 8 extend within the cylinder to its front end where they are carried by bracket 9 having a handle 12 extending through a slot 11 in the front wall of the cylinder 2. Between the bars of each pair of bars 8 is movable a set of ten types 13 for printing numerals. For shifting the entire set of types there extend in front of and behind the same and between the bars 8 of each pair two arms 15 of a setting slider 16, the two arms of a slider being connected together by a pair of bars 14:, as

shown in Figs. 1 and 3. Each type 13 has a slot 17 into which enters a guide pin 18 fast in the pair of bars 14, so that when the pairs of bars 14 are moved upwards the types 13 are driven away from the-wall of the cylinder.

At the front end each setting slider 16 carries a setting lever 20 mounted to rock about a horizontal axle 19. The free ends of these levers extend each into a longitudinal slot 21 of the cylinder 2, but normally only so far that they do not project beyond the periphery of the latter. In order to engage the levers 20 and to shift the slides 16 by means of them for setting any one of the types 13 in relation to an aperture 22 in the cylinder 2, tl e bars 8 must be moved upwards by the handle 12. A presser 23 is movable longitudinally in the middle of the wheel-shaped handle 12 and at its inner end carries a laterally directed arm 24. lVith the latter there is firmly connected a rod 25 that extends lengthwise in the cylinder 2 and engages under the action of a spring, not shown, in a recess 26, whereof two are arranged one above the other in the end wall. If the presser 23 is driven inwards the rod 25 is disengaged from its recess, whereupon the handle 12 can be set in the upper and men be moved into the lower position. In the upper positionof the handle 12 the levers 20 extend so far out of the cylinder 2 that they can be conveniently gripped, as shown in dotted lines in Figure 1. Between the bars of each pair of bars 8 there is opposite the aperture 22 in the cylinder a stop 27 which is firmly connected. with the said bars and causes the type 13 under it to enter into the aperture 22 when the handle 12 moved downwards, so that the outer end of the type in the aperture 22 is flush with the printing face 28 of the cylinder 2. In order that the types 13 can slide readily over the stop 27 serving as an abutment for them when the setting slider 16 is shifted, both the stop and the types are bevelled in front and behind and have slanting faces 2'? and 13, respectively.

The types are set exactly in relation to the aperture 22 with the aid of notches 29 formed inithe back of each setting slid-er 16., and a pawl 30 pressed downwards by a spring 31 on to the slider 16 or into a notch 29 therein. All the pawls 3O pivoted on an axle 33 that is common to them all ad has its ends held in side plates 32; Leve" 3 1 are pivoted beside the pawls 30 on the 1 de and have each a lateral pin 35 engaging in a slanting slot 36 in an allotted setting slider '16. When the latter is shifted endwise the allotted lever '34 is moved upwards more or less,correspondder 2. Each slide 38 is connected an outwardly extending arm 38"with a transverse cam 10 which has its one end fork-ed and is guided to move transversely of the cylinder 2 on a rod 41 which extends lengtltiwise of the cylinder and is attached thereto. The five cams ll) are equally spaced apart at the cylinder 2 in the direction of its length. In the path of each cam 10 below the cylinder and lying transversely of the latter is a lever 42; these levers are pivot-ed on an axle 13 that is common to them all and are pressed upwards each by a spring 1 1-. i

To ensure that all the levers shall lie in their upper end position at exactly the same height, a bar 45 reciprocated up and down by a bell crank 16 is arrang d below them. F or actuating this lever 16 it is firmly con nected with a lever 1'1" carrying an antifriction roller 18 that bears under spring pressure on the periphery of a cam fa on the eviinder 2. Each lever 12 carries within reach of the allotted cam 40 an antifriction roller 50 and engages at its free end by means of a lateral pin 51 in a slot 52 of a vertical toothed rack 53.

Owing to the vertical reciprocation of the lever 42 the racks 53 are n ved up and down, in each case a shorter longer distance ac cording to the position of the allotted cam 40. Only the downward movement of the toothed racks out of their upper end 3: sition is transmitted to two pinions ant. 55. for each rack, which pinions are connected each with a numeral disc 56 and 5'? respectively of two counting devicesarrangzed one above the other. The iipper of these counters serves for rendering visible the total sum recorded, whilst the lower counter serves for printing this total on a check strip, not shown, and for this purpose has types on the periph omitted.

cry of its discs. If a double control is not required one of the two counters may be In order that the upward. movement of the toothed racks 53 shall be inoperative on the counters, the racks are disengaged in the lower end position each by a cam 58 by means of a lever59, said cam 58 being arranged on the periphery of the cylinder 2. Each lever 59 engages ina recess in a double link 61 which couples together two three-armed le- 1 vers 62 and 63. These levers are freely rotatable each on an axle 64 and 65 respectively, which axles enter into slots 66 in the toothed racks 53; The upwardly directed arms of the levers 62 and 63 carry anti-friction rollers 67 situated each in the slot 66 of the allotted toothed rack. A third arm of each of the lGVcIS 62 and 63, which are arranged one above the other, engages between the numbered discs of the counters and has an upwardly directed stopor tooth. 68 which, when the toothed rack is disengaged, as shown in Figure 9, engages in a locking ring (if) of the teeth fast on. the allotted numbered disc and thereby locks the latter against rotation.

When the link 61 moves upwards the levers G2 and 63 are rocked so that their upstanding arms throw the racks into engagement with their pinions, whilst their arms carr ing the teeth 68 release the numeral discs. Reverse ly, when the link 61. moves downwards the toothed racks are disengaged from their pinions by the levers 62 and 63 and the numbered discs are locked. i

In consequence of the individual drive of the first five numeral discs of each counter, corresponding to the highest number of place values present in the printiugcylinder, the tens must he transferred from four numeral discs, i. e. from the units disc to the tens disc, from this to the hundreds, from this to the thousands disc and from this to the ten-thousands disc with the aid of a second or auxiliary feed device described hereinafter. The tens are transferred by the other discs each to the next disc in the manner customary in counting mechanism by means of intermed Sate toothed wheels. The said second or auriliary teed device comprises above the toothed rack for driving the tens discs. here in referred to briefly the tens rack, as well as above the hundreds, thousands and ten-thousands rack. a tumbler or detent 70 which is pivoted at 71 on a lever 73 tulcrumed at 72, and is held by a spring 74 against a stop 75. The lower end of each lever 73 lies in the range of a. cam 76 of the numbered disc of the next lower place value and. at each revolution of this disc or cam, is so roe red that an upwardly directed tooth 70 of the tumbler 7 0 arrives in front of a downwardly directed tooth. 77 of a lever 77 extending over the said tumblen The four levers 77 are mounted on an axle 78 common to them all and are connected eaichby a bail or stirrup 79 to one end of a lever 80.- The other end of each lever 80 carries an anti-friction roller 81 which bears against a cam 82 of thecylinder 2 and is so controlled by the latter-that the allotted lever 77 is moved a distance up and down which sufllces. after the lever77 has struck the tooth 70 of the tumbler 70 under it, to move downwards by means of thelatter the allotted toothed rack a distance equal to one tooth, i. e. one unit of the allotted numeral disc, and to feed the latter one number.

In order thatthe transference of the tens shall take place always in the correct order,

ire. from a lower place value to-the numeral disc of the higher place value, the four cams 82 are staggered one relatively to another an amount such that the lever 77 of the next higher place value is actuated only after the lever of the next lower place value has-been moved downwards. As the second or auxiliary feed: device for the transference'of tens must be actuated subsequently to the ordinary feed of the numbered discs by the cams 40,

and'always from the same starting or initial" rock freely downwards without striking the tumbler 70 and without effecting a supplementary feed of the numeral discs inquestion.

A hollow table 83 is provided for hearing the letter or the like to be printed, for example impressed with a currency value for franking it, which letter or the like is fed by a roller, not shown, at a suitable moment to the printing cylinder from below the latter.

The described machine is manipulated and operates, briefly, as follows In a predetermined position of the printing cylinder 2 and when the bars 8 are set in their upper position, the types 13 for effecting the printing are set at the aperture 22 of the cylinder by means of the levers 20 extending out of the latter and, when the bars 8 are moved down wards, are moved into the saidaperture, i. e. into the printing position. When the types are being set in the printing position the cams 40 are set, by means of the levers 34 and slides 38, in a position relatively to the cylinder corresponding to the set numeral of the place value in question, so that each projects more or less beyond the cylinder. When the cylinder is then turned by hand or by a motor, the types and, if desired, a mark-cliche surrounding the same, are provided with ink by an inking device, not shown, and caused to print a. letter or the like lying on the table 83. During the rotation of the printing cylinder the cams coact with the levers 42 and move these downwards, each according to the position of the allotted cam, against the action of the springs 44. The toothed racks 53have previously been engaged with the pinions 54 and 55 by the lever mechanism 59, 61, 62, 63 and are moved downwards more or less by the levers 42, and they rotate the said pinions and counter discs a corresponding angular distance. If duringthis rotation a numbered disc passes its zero position its cam 76 rocks its lever 7 8 and places the tooth 7 0 of the tumbler 7 0 under the allotted lever 7 7 whose tooth 7 7 prevents the tumbler from returning into its normal position. its soon as the toothed racks 53 have arrived into their lower position they are disengaged by the cam 58 from the pinions 54 and 55, whereupon they are moved under theinfluence of the springs 44 into the upper position limited by the tumblers 70. The auxiliary or second feed device for transferring the tens then operates, beginning with the tens rack anc. ending with the ten-thousands rack. Only that toothed rack is moved downwards one tooth, however, whose allotted tumbler 7G for transmitting the downward movement of the allotted lever 77 is set on the rack. All the other toothed racks remain in their upper end positions. After this second feed move- .ient and the stamping of the letter or the like have taken place, the machine is ready for producing a new stamp, mark, impression or the like, and the described cycle of operations is then repeated.
