Arm 9 has a cam United States Patent M COMBINED TAPE FEEDING, SEVERING, AND DELIVERING MECHANISM Kurt Aurbach, Bielefeld, Germany, assignor to Anker- Werke, A. G., Bielefeld, Germany, a corporation of Germany Application July 20, 1950, Serial No. 174,831 Claims priority, application Germany October 6, 1949 Claims. (Cl. 164-49) The invention relates to cash registers, calculators, accounting machines and the like business machinery and, more particularly, to devices for'printing and issuing a check, voucher or other record in such machinery.

In the known machines of this kind, the control means that actuate the cutter for severing the printed record slip from the supply tape are separate in design and location from the means for dispensing the slip.

It is an object of the invention to improve the record producing and issuing mechanism of business machines toward a simplified design of greatly reduced space reguirements as compared with the corresponding known evices.

To this end, and in accordance with a feature of the invention, the drive structure for operating the perforating or cutting device is designed as a guide for issuing the check or record thus eliminating the need for separate dispensing devices.

These and other objects and features of the invention will be apparent from the example of a check-dispensing printing device according to the invention described in the following and illustrated on the drawing, in which Figure l is a side elevation, Fig. 2 is a sectional top view, Fig. 3 is a sectional detail view on a larger scale of elemerits in the left top portion of the device as illustrated in Fig. 1, and Fig. 4 is a perspective and exploded view of the same elements.

The illustrated check printing and issuing device has a stationary frame structure composed of two

parallel wall plates

1 and 2, which are rigidly fastened together and spaced from each other by three screw bolts 3, 3a, 3b. The bolt 3 forms the pivot of a drive member 4 for actuating the reciprocable blade 5 of a tape cutter. The drive member 4 is designed as a curved surface structure and has bracing corrugations or ribs 6 which serve also as rails for guiding the severed checks from the cutter blade 5 to the dispensing opening of the device. Mounted on the back of the curved drive structure 4 are a projection 7 with an arm 9, and a projection 8 on which a roller 10 portion engageable by

dog pins

11 and 12 of a cam disc 14 which has a cam projection 13 in engagement with the roller 10 and is mounted on a cam shaft 15. During the machine operation, shaft 15 with cam disc 14 performs a clockwise revolution (Fig. 1). During that revolution, the cam projection 13 moves the roller 10 away from the cam shaft, thus turning the drive member 4 clockwise about bolt 3 so that the cutter blade 5 is shifted toward the right into its active position. Immediately thereafter, the pin 11 engages the cam end of arm 9 and returns drive member 4 and cutter blade 5 to the illustrated rest position. In the illustrated position of cam disc 14, member 4 and blade 5 are secured in the rest position by the pin 11.

Drive member 4 is linked with the cutter blade 5 by projections 16 of arm 4 which pass through corresponding openings of the blade. The blade is guided between a top plate 17 and a traverse 18 (Figs. 1, 3, 4). A spring 19 (Figs. 3, 4) between plate 17 and traverse 18 serves to force the cutter blade 5 toward the top plate 17 but can become effective only to an extent permitted by discs or washers 20 disposed between plate 17 and traverse 18. The stationary counter blade of the tape cutter, for coaction with the cutter blade 5, consists of a plate 21 which is mounted in a traverse 22 by means of angle pieces 21a and together with a blade 21b (Figs. 2, 3, 4).

The check tape 25 to be printed is supplied from a 2,698,660 Patented Jan. ,4, 1955 9 reel 25a revolvably mounted on a stationary reel shaft 26 and passes over a guide roller 26a to a driven feed roller 24. Roller 24 coacts with a pinch roller 23 to feed the tape over a guide 26b through a slot 260 and across the path of the cutter blade 5 into a chute bordered at one side by the above-described curved guide surface of the drive member 4 and at the other side by a sheet-metal cover plate 27 partly surrounding the tape reel 26. A sheet-metal guide 28 adjoining the pivoted lower end of the drive member 4 forms a slide surface for the checks to be issued so that they reach the bottom of guide 28 from which they can readily be removed through the outwardly flared check dispensing opening formed'between plates 27 and 28.

The check printing place is located between the guide roller 26a and the feed roller 24 (Fig. 1). The printing is done by printing platens o1

hammers

29, 30 which, when moved upwardly, force the adjacent tape portion together with an intermediate ink ribbon (not shown) against the type carrying means of the machine schematically shown at 31 (Fig. 1). The lower end 32 of hammer 29 abuts against a nose 32a of a control lever 34 pivoted on a shaft 35. Lever 34 carries a roller 36 which acts as a cam follower in cooperation with a cam 33 on cam shaft 15. The lower end 37 of hammer 30 abuts against a nose which is shaped and arranged like nose 32a but appertains to another control lever pivoted on shaft 35 and coacting with another cam 33a (Fig. 2) of cam shaft 15. During the revolution of cam shaft 15, the

cams

33 and 33a cause the control levers to lift the printing hammers at the proper moment to produce an imprint on the check tape portion then located at the printing place.

The driven feed roller 24 (Fig. l) is actuated from the cam shaft 15 to operate in the necessary time relation to the printing and cutting devices. To this end, a gear 38 on cam shaft 15 has one or several peripherally limited series of teeth that enter into an intermittent meshing engagement with a pinion 39. Driven from pinion 39 is a train of gears 40, 41, 42 of which the gear 42' meshes with a pinion on the shaft of the feed roller 24.

The operation of the device as a whole is as follows. When, during the machine operation, the cam shaft performs its revolution, the

printer control cams

33, 33a first actuate the

printing hammers

29, 30 so that a check is printed on the tape portion between

rollers

26a and 24. Then, the teeth'of gear 38 temporarily actuate the feed roller 24 through the connecting gear train 39 to 42 and advance the tape an amount corresponding to the length of the printed check to be issued. In this manner, the printed portion passes through the slot 260 beyond the cutter blade 5. Next, the cam projection 13 of the cutter control cam 14 engages the roller 10 and turns the cutter drivemember 4 clockwise about pivot bolt 3 so that cutter blade 5 moves beyond the edge of counter blade 21 and cuts'the printed check from the tape. The severed check drops into the chute between the rocking drive member 4 and the cover plate 27 and slides over the inclined surface of plate 28 to the check dispensing opening.

If so-called double checks are to be issued, the printing and cutting operations are repeated in such a manner that the first operation of the cutter blade merely perforates the tape while the second operation, occurring after the second printing, cuts the printed double check off the tape. in order to permit such an operation, the cutter blade is preferably given a serrated cutting edge as shown in Fig. 2, and it is necessary to provide cam 14 with a second cam projection 13 shaped to advance the cutter blade only to the extent required for perforating the tape.

It will be apparent to those skilled in the art upon a study of this disclosure that the invention is not limited tothe design specifically embodied in the described and illustrated example but can be modified in various respects and inaccordance with the requirements and desiderata of the particular application, type, and construction of various business machines, without departing from the objects and essential features of the invention and within the scope of the claims annexed hereto.
