Divided and. this application filed January 31, 1930. Serial No. 425,003.

This invention relates to auditing machines of the ty e disclosed in Letters Patent of the United tates No. 1,694,009, granted to Maximilian M. Goldberg, December 4, 1928, and

5 more particularly refers to printing mechanism for such machines.

The subject matter of the present invention forms a division of ap licants co-pending application for Letters atent of the United States, which has issued into Patent No. 1,818, 17 3, on August 11, 1931.

It is an object of the present invention to provide an improved and a novel impression taking mechanism for auditing machines of the type disclosed in the above referred to patents.

Another object is to provide in a printing mechanism, a hammer retracting member and means carried by the hammer retracting member operating means to trip the hammer.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred formor embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

General description The record strips may beproduced on the machine itself, in a manner set forth in the parent case, or they may be pre ared on a machine of the type disclosed in tters Patent of the United States N 0. 1,506,056, granted to Maximilian M. Goldberg August 26, 1924. When produced on the machine of this patent, the record strip is known as a detail record strip. 7

When such a detailed record strip is run through the auditing machine of the parent case, the data are analyzed and accumulated on the totalizers according to classification, size, etc. The detail record strips may be prepared in a number of different depart ments of the same store, or in the several stores comprising the system of chain stores, during a certain period of the business, and then they may be sent to the central oifice to be run through the auditing machine of the type disclosed in the parent patent for analyzation.

After all of the detailed record strips have been run through the auditing machine, the machine may be operated to produce either a summary record strip. having control points located thereon in a similar arrangement to those on the'detail record strip, or the machine of the parent case may be controlled to produce a printed record known as a grand summary record strip, on which is printed legible characters interpretating the series of control points on the summary record 7 strips.

In addition to printing legible interpretations of the grand summary record, the ma-. chine also functions to print interpretative symbols on the detail record and on the summary record strip.

Reference may be had to the parent case for illustrative embodiment of the auditing adapted to be used, and also for facsimile disclosures of the detailed record, summary record and grand summary record strips.

Detail description The mechanism disclosed in the parent patent for printing the indicia on the several records forms the subject matter for the present application and will now be described.

This printing mechanism includes a platen 1953 supported in a channel carried at the free end of an arm 1954 fast on a shaft 1955, suitably supported in a frame 195 (Fig. 6)

and which is adapted to be first retracted and then released and thrown sharply against the group of type carriers, only one, 1875, of which is shown herein, mounted on a rod 1834, to take legible impressions from types carried on the type carriers. The rod 1834 is suitably supported in the frame-195.

Another arm 1956 (Figs. 4 and 6)- having its hub secured to the shaft 1955, adjacent the frame 195 carries a stud 1957 which, under the influence of gravity, normally rests in a cradle formed in the free end of an arm 1958 of a bell crank, pivoted'on the shaft 1955. A spring 1961 normally presses the end of the other arm 1959 of the bell crank, against a shaft 1963, suitably supported in the frame 195, and in another frame not shown herein.

A shoulder 1970 on a coupling pawl 1969, pivotally carried on the free end of an arm I 1968 journaled on the shaft 1955 is normally held by a spring 1971 in co-operative relation with a shouldered block 1965 secured to the free end of an arm 1964 pivoted 011 the shaft 1955 and joined to the arm 1958 by a hub.

An arm 1967 projecting downwardly from the arm 1968 is provided with teeth meshing with teeth on the end of an arm 1974 of a lever journaled on the shaft 1963, and a stud 1976 on the other arm 1975 of the lever projectsinto a cam groove 1652 in the side of the gear 1650 rotatably supported on a shaft 1651, suitably supported in the machine. Any suitable means may be employed to rotate the gear 1650 one complete counter-clock-v wise rotation at each total taking operation of the machine, to rock the lever comprising arms 1974 and 1975 counter clockwise and then clockwise to normal. As this lever rocks counter clockwise, the toothed end of the arm 1974 meshing with the toothed segment arm 1967 of the bell crank comprising arms 1967and 1968 rocks this bell crank clockwise about its pivot on the shaft 1955, and due to the coupling pawl 1969, draws the arm 1964 and arms 1958 and 1959 clockwise therewith, gravity causing the arm 1956' and the hammer arm 1954 to follow, withthe stud 1957 still resting in its cradle in the arm 1958.

As the movements of these parts progress in the directions indicated, a finger 1977 pro jecting from the arm 1974 comes into contact with a stud 1978 on the tail of the pawl 1969 rocking this pawl clockwise about its pivot on the arm 1968, eventually releasing the arm 1964 and the bell crank comprising arms 1958 and 1959 to the action of the spring 1961, which immediately rocks the bell crank and the hammer arm 1954 violently counter clockwise until the movement of the bell crank is arrested by the arm 1959 striking the shaft 1963, at which time the accumulated momentum of the hannner arm 1954, carries it further on its clockwise travel to bring the platen 1953 into sharp contact with the types to take the impressions therefrom, after which gravity, assisted by the rebound caused by the somewhat resilient platen, 1953 restores the hammer to its normal position where the stud 1957 again rests in its cradle in the arm 1958, as viewed in Fig. 4.

At this point in the operation of the ma chine the several parts, not including the hammer arm 1956, occupy the positions in which they appear in Fig. 3 of the drawing.

Continued counter clockwise rotation of the gear 1650 and the cam groove 1652 in the side thereof, rocks the lever 1974 and 1975 clockwise rocking the bell crank comprising arms 1967 and 1968 counter clockwise to carry the latch pawl 1969 therewith. As the finger 1977 recedes in a clockwise direction, it gradually releases the pawl 1969 to the influence of its spring 1971, which rocks the pawl counter clockwise about its pivot, at the same time the arm 1968 is carrying the pawl bodily upwardly'toward its normal position. This compound movement of the pawl 1969 brings the face thereof against the shouldered block 1965, at which time the finger 1977 breaks contact with the projection 1978, and continued counter clockwise movement of the arm 1968, under the influence of the arms 1974 and 1975 continues to raise the pawl 1969 upwardly relative to the arm 1964. Shortly'before the pawl1969 arrives in its normal position, the shoulder 1970 thereon passes the shoulder 1966 on the block 1965 whereuponthe spring 1971 rocks the pawl further counter clockwise to position the shoulder 1670 thereon above the shoulder 1966 on the block 1965. The parts at the end of the operation occupy the positions in which they appear in Figure 1 of the drawmg.

Mechanism is operated by the impression hammer operating mechanism to align the printing type wheels 1875. i

A series of aligning fingers 1983, only one of which is shown herein, pivoted on a shaft 1982, are adapted to be rocked into co-operative relation with the aligning teeth on the type wheel 1975 to hold them in the position to which they are set. Springs compressed between a spring seat rod, carried between a pair of arms 1984, only one of which is shown herein, on the shaft 1982 and the tail of the aligner pawls 1983, normally press the tails against a stop rod 1985 carried between the arms 1984.

A cam arm 1988 (Fig. 2) liubbed to the lever comprising arms 1974 and 1975 is provided with a cam slot embracing a stud 1987 projecting from a pitman 1986 having its up per end pivotally connected to one of the arms 1984 and being bifurcated at its loweI end to slide on a collar secured to the shaft 1963.

The first movement of the arms 1974 and 1975 under the influence of the cam groove 1652 is counter clockwise, which carries the cam arm 1988 therewith, thrusting the pitman 1986 in the direction of its length away from the shaft 1963 to rock the aligner frame comprising the arms 1984, the spring rod and the stop rod 1985, counter clockwise to engage the several aligner fingers 1983 with their respective type wheels 1875, the pitman 1986 moving the arm 1984 slightly beyond this point to further compress the aligner springs. V

The restoring movement of the arms 1974 and 1975 and the cam arm 1988 draws the pitman toward the shaft 1963 and disengages the aligner fingers 1983 from the type wheels.
