United States Patent PRINTING DEVICE FOR STATISTICAL CARD PUNCHING MACHINES William Wockenfuss, Union, -N. J., assignor, by mesne assignments, to Burroughs Corporation, a corporation of Michigan Application March 4, 1950, Serial No. 147,610

17 Claims. (Cl. 197-1) always in the same fixed position relative to an edge of the card, the usual position being along an edge thereof above the columns in which the index points are punched.

The present invention provides a printing device by means of which a line of characters may be printed in any preselected area of a card by preliminarily adjusting the printing head of said device to the desired position where it will print said characters as the punching of the card progresses.

Another feature of the invention resides in the provision of a printing head adjustable to various positions between opposed edges of a record card and comprising a plurality of printing elements selectable in various combinations to form difierent characters, and wherein operable members, each individual to one of said characters, control the actuation of various combinations of said printing elements to print the characters when the members corresponding thereto are operated.

The inventive idea involved is capable of receiving a variety of expressions one of which, for purposes of illustration, is shown in the accompanying drawings; but it is to be expressly understood that said drawings are employed merely for the purpose of facilitating the description of the invention as a whole and not to define the limits thereof, reference being had to the appended claims for this purpose.

Fig. 4 is a fragmentary plan view of said unit, taken on the line 44 of Fig. 3;

Fig. 5 is a fragmentary rear elevation, partly broken away, of the print head adjusting unit;

Fig. 6 is a fragmentary front elevation of said unit taken on the line 6-6 of Fig. 3; and

Fig. 7 is a diagrammatic view of the solenoids and their circuits for operating the printing elements of the print head, and also illustrating one of the key operated mem bers and its contacts necessary to selectively energize certain of said solenoids to print one of the characters which may be formed by a combination of said printing elements.

The invention is illustrated, generally, in its adaptation to the type of machine disclosed in the Mills Patent No. 2,046,082, dated June 30, 1936, wherein key operated members are utilized to control the operation of the punches and that of a plurality of type sectors which imprint a line of characters in a fixed and unalterable position along the upper edge of a record card. As distinguished therefrom, the machine herein disclosed has but a single printing head substituted for the plurality of type sectors of said patent and which is capable of adjustment relative to a record card so as to be positioned to print in any desired area of said card located between opposed edges thereof.

As shown in Figs. 1 and 2, the card punching machine to which the present invention is applied comprises a main casing 10 above which is supported the usual card carriage 11 adapted to receive a record card 12, indicated in dot and dash lines, that is advanced with said carriage in a step-by-step movement relative to a row of punches 13 by a mechanism within said casing which may be similar to that shown in said patent and which forms no part of the present invention. Cards are fed to the carriage 11 from a magazine 14 by a known picker mechanism generally indicated at 15 and, after being punched, said cards are deposited into a receptacle 16 at one side of the casing 10. The operating mechanism for the punches 13 may be controlled, as in said patent, from the keys 17 mounted in the lower front portion 18 of the casing 10, each key being individual to an alphabetical, numeric, or like character to be printed.

The printing device of the present invention comprises a single print head 19 consisting of a plurality of printing wires 20 (Fig. 3) each encased in a flexible cable 21 and closely grouped in said head and adapted to be momentarily projected therefrom in various selectable combinations each capable of printing a character identified by one of the keys 17. At the ends of the wires 20 remote from the head 17 they are each connected to the core of a solenoid 22 enclosed within a housing 23 mounted above the keyboard. In Fig. 7, the thirty-five solenoids 22 are shown as having one terminal of the winding of each connected to a common conductor 24 leading to a suitable current source, while the other terminal of each solenoid winding is connected to a bus bar 25 individual thereto. Joined to the various keys 17 are a plurality of operating bars or members 26 utilized in any suitable manner, such as shown in the above mentioned patent, to operate the punches 13 individual to said keys, and each of said bars carries a conducting strip 27 which is individual to the particular character to be printed by the head 19 and Whose code is to be punched in the card 12. As an example, said bar 26 and its conducting strip 27 shown in Fig. 7 identify the letter A and, for this character, the strip 27 carries eighteen contacts 28 which engage with associated bus bars 25 when the bar 26 is operated by a depression of the key 17 for said character. The strip 27 is connected to the other line conductor 29 which is multipled to the various other strips 27 each of which carries different sets of contacts 28 that are adapted to engage the bus bars 25 for the energization of various groups of solenoids which are then energized to operate their printing elements 20 to print characters identified by said sets of contacts.

As will be seen from the full and dotted line positions of the head 19 in Fig. 1, the same is capable of adjustment in two directions one of which is vertical and the other horizontal with respect to the card 12. Thus, with the head in the full line position, a horizontal line of printing may be accomplished along and adjacent the upper edge of the card or along the lower edge as indicated in dotted lines, or said head may be adjusted to any position intermediate those illustrated. Also, depending upon whether all columns of the card or a lesser number thereof are to be punched, the head may be adjusted horizontally to a position at the extreme left end of the card directly in line with the first column thereof or may be moved to any intermediate horizontal position. Associated with the head 19 is a guide 30 through which the ribbon 3]. extends, and in order to permit of the free movement of the ribbon through said guide when the head is adjusted to a preselected vertical position adjacent the upper or lower edge of the card, the feed and take-up reels 32 for said ribbon are mounted in brackets 33 for pivotal movement about horizontal axes.

The printing head 19 and ribbon guide 30 are secured to the upper end of a vertically adjustable member 34 in the form of a bar having rack teeth 35 along one edge and being serrated at 36 along its other edge and said bar is a part of the head adjusting unit illustrated in Figs. 3 to 6. Said unit is enclosed within a housing 37 and comprises a stationary frame consisting of end pieces 38, only one of which is shown in Fi gs. 3 and 4. Said pieces 38 have secured to the ends thereof the parallel, longitudinally arranged rack bars 39, and extending upwardly from the center of each of said pieces 38 is the vertically disposed bracket 40 through the upper flanged end of which extends a screw bolt 41 that supports the 'yoke member 42 that has connected thereto a guide bar 43, the purpose of which will later appear. The stationary frame of the unit also includes an upright 44 at each end thereof and at the rear of the end pieces 38, and said uprights have attached thereto a horizontal guide rail 45.

The vertically adjustable member 34 extends between opposed guide plates 46 and is slotted at 47 (Fig. to receive guide pins 48 carried by one of said plates. Upper and

lower guide rollers

49 and 50 on the opposed guide plates 46 engage, respectively, the rail 45 and the lower edge of the rear bar 39 to guide the movable assembly of the adjusting unit including the member 34 in its horizontal movements when the head 19 is being adjusted longitudinally of the card 12. Spring urged detents 51 (Fig. 5) disposed between the guide plates 46 engage the serrations 36 of the member 34 to frictionally retain said member in its vertically adjusted positions.

To vertically adjust the member 34, and consequently the head 19, a shaft 52 having a turning knob 53 on its outer and extends through a slotted plate 54 secured to the front of the housing 37, and said shaft then extends transversely over the stationary frame which includes the rack bars 39 and through a bearing aperture in laterally extending portion 46x of the forward one of the plates 46. Said shaft 52 carries upon its rear end a gear 55 which meshes with the teeth 35 of the member 34 so that turning of the shaft in one direction or the other will raise or lower said member 34 and the attached head 19.

The horizontal adjustment of the head 19 lengthwise of the card 12 is accomplished by a second shaft 56 having a turning knob 57 secured to its outer end. Said shaft surrounds the shaft 52, and between the knob 57 and the plate 54 there is interposed a pointer plate 58 apertured to receive the shaft 56 and having opposed inturned flanges 59 that engage the upper and lower edges of the slot formed in the plate 54. The pointer of the plate 58 moves over a card column indicating scale etched or otherwise formed along the upper edge of the plate 54. Within the housing 37, the shaft 56 has secured thereto the two gears 60 suitably spaced on the shaft so as to engage the teeth of the rack bars 39 so that as the shaft is rotated in either direction the entire movable portion of the adjusting unit including the two

shafts

52 and 56, the plates 46 and the member 34 will be guided along the bars 39, with the pointer 58 moving along the graduations on the plate 54 to indicate the desired columnar position to which the head 19 is to be adjusted. An elongated plate 61 loosely mounted upon the shaft 56 between the inner edges of the flanges 59 and the front gear 60, carries the spring urged detents 62 which engage the teeth of the adjacent rack bar 39 and act to frictionally retain the movable assembly in its selected position of horizontal adjustment.

Intermediate the ends of the shaft 56, the same has secured thereto a sleeve 63 carrying a series of friction discs 64 which are engaged by the guide bar 43 when the adjusting unit is completely assembled, and the engagement of said bar with the discs retains the shaft assembly against any slight upward movement and also maintains the gears 60 in engagement with their respective rack bars as the knob 57 is turned to horizontally adjust the head 19. The shaft 52 and the

rollers

49 and 50 provide threepoint support for the movable assembly comprising the plates 46. The gear 55 entering between the plates 46 provides additional guidance for the movable unit.
