Claims. 1

This application is a division of my copending application, Serial No. 578,507, filed February This invention relates to printing machines and particularly to printing machines adapted for use in accounting work to produce accounting records and the like.

In the preparationof accounting records, situations often arise wherein it is desirable to perform posting operations in respect to a large number of accounts, and to afford a novel and effective printing unit for accomplishing such posting operations is an important object of this invention.

A further object of the invention is to simplify the posting of records, and more specifically, it is an object of the invention to enable a posting unit for operating on such cards to be so constructed and arranged that it may be readily set in different positions so as to accomplish the posting operation in different areas of the cards or records in accordance with the setting of the posting unit.

It is a further object of the present invention to enable such a posting unit to be operated in a manner that facilitates shiftable mounting of the posting unit. A more specific object of the invention is to operate the posting unit of the apparatus through a Bowden cable connected from the sensing means, thereby to cause operation of the posting unit each time the sensing means are operated through a sensing cycle.

For purposes of disclosure the invention is herein illustrated as embodied in a posting unit 80 that forms part of an accounting machine In that is described in detail in my aforesaid parent application Serial No. 578,507. The machine l0 makes provision for automatic and sequential feeding of cards C, Fig. 2, into and along a sheet guideway that is formed on the table top T by an under cut rear guide and under out front guides 41 and 41A. The card feeding movement is attained by a constantly driven feed belt 38 and one or more cooperating presser rollers 13, and each card C is brought to rest momentarily at an operating or working station by a stop finger 60 so as that a data sensing operation may be performed by a sensing head 10 and a posting operation may be performed on the card by the posting unit 80.

As explained in detail in my aforesaid parent application, the card C has a money amount rep resented therein by coded perforations which are sensed by the sensing head 10 and entered into an accumulator, and as an accounting record showing the fact of such sensing and adding'of the money amount from a card 0, a printed indica- Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show a preferred embodiment of the present invention and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle.

Other embodiments of the invention embodying the same or equivalent principle may be used and tion such as the word Paid is printed in an appropriate space on the card C by the unit 80.

In order that such operations may be performed at successive intervals, the card has a large num--" ber of such spaces, and the printed impressions may be made in different selected-positions on the card by setting or mounting the posting unit serves to operate the sensing means 10 and the posting unit 80 while the shaft 44 operates the stop finger 60, as will be described hereinafter. As herein shown, the stop finger comprises a plate 6| disposed transversely of the sheet guideway G and pivoted by a mounting stud 62 on the forward end of an arm 63 that is in turn pivoted on a supporting shaft 64. The arm 63 extends rearwardly from the shaft 64 and has a roller 65 disposed as a cam follower beneath the edge of a stop finger cam 66 mounted on the stop finger cam shaft 44. It will be observed that the stop finger plate 6| has a slot 6'! cut in its lower edge so as to afford clearance for the belt 38, and when the-stop finger plate 6| is dropped to its lower position by the action of the cam 66, the edge 21 91th? card C will move into abutment with the adjacent face of the plate BI so as to be held in the operating position beneath the sensing means 10 and the posting unit 80.

When the card C has been stopped and accurately located in the operating position as described in my aforesaid parent application, the machine operates to effect the'desired sensing and posting operations, and the numerical amount that is represented by the perforations is sensed by the sensing means I0, and the word Paid is printed at the same time in the appropriate space of the card C by the .posting unit 80. The sensing means I0 are in the presentinstance carried by a rocker I05 having cam rollers I06 thereon that are engaged by appropriate cams I0! mounted on the shaft 40 andcooperating with the cam rollers I06 so as to actuate the rocker arm I05 in a downward direction each time the shaft 40 is rotated. The downward movement of the rocker arm I05 takes place in impression on the'ca'rd C being determined by each cycle of operation of the machine at the time when the card C is located at rest in the operating position as defined by the stop finger 60, and. the downward movement of the rocker arm I05 is utilized in the present instance to effect downward sensing movement of the sensing means I0; 'Thus, the rocker arm I 05 has a casting IID extended from its forward edge and this casting has mountingmeans thereon whereby the se'nsinghead I0 is' supported on the arm I05.

At-the time when the sensing means 10 are operated to sense the perforations '25 in a card C, the pos'ting unit 80 or the present invention is'operaited to print the word "Paid in the appropriate space I I of the posting area I5 of the card; and such operation of the posting unit is attained by means of a Bowden cable I60, as shown in the drawings. The Bowden cable I60 has oneie'nd of its sheath anchored in a bracket IBI that is mounted on a housing portion 40'A of I the machine just above the outer end of V the rocker; I05, and the corresponding end ,of the Bowden wire 160A is connected to the casting I I0 by a connectorfittin'g I62. The other end of the sheath 0f the Bo'wden'cable' I60 is connected, as sh'owriin Figs. '1 and 2, to the upper wall of the posting unit by a hub -I 83A and a clamping screw I63 so that in the course of downward movement of the sensing means 10, the Bowden wire I'BBA is so actuated that the end thereof that is disposedwith'in the posting unit 80 is moved in an upward direction, and this causes posting operation of the posting unit', as will be hereinafter described. 4

The posting unit as herein shown comprises a pair of side plates "0 and III that are secured at their lower edges by screws "2 to opposite edges of a base plate I'I 3, andthe side walls I10 and "II'I are connected at their upper edges by a top plate I14 that is secured to the side plates by screws I15; The forward end, that is, the righthand' end as shown in Figs. 1 and 2 of the drawings, is closed by an end wall I'IG that is connectedto the side walls I10 and If by screws ITI." Within the housing that is thus afforded, a rocker'I 80' is pivoted on a transverse shaft I8I, and a spring I82, acting between the rocker and its stationary transverse shaftl83, is operable to urge theleft-ha'nd end'of the rocker I80 to the elevatedor' inactive position shown in Fig. 2. The end of theBo'wden wire IA has a connecting fitting'lfid secured to the end thereof. within the housing and this fitting is pivoted at I85 to theright-ha'nd endof the rocker 180, and when the Bowden wire I60 is actuated in a downward the location in which the posting unit is disposed, as will hereinafter be explained in detail.

When the printing element I is in its elevated or inactive position shown in Fig. 2, it is in a reversedo'r upwardly facing position and is in contact with a downwardly facing inking pad 'I9I, this inking pad being carried on a rockably supported mounting block I92, This mounting block is generallysoiuare'cross section, and is held in a position where the inking pad I9'I faces downwardly, as shown in Fig. 2, by a spring biased de'tent arm I93 that is pivoted on the transverse shaft I83 and is urged downward-1y against the flat surface of the m untin bar I 92 by a spring I94. When the user desires to apply ink to the ink pad I' 9I, the mounting bar I92 may be rotated by a knurled operating handle thatis' connected to the mounting bar I92 and is disposed o'ii-tside of the side wall "-0 of the posting'unit. Thus, the pad 191 may be faced upwardly for the application of ink thereto, and in such rotative movement of the mounting bar I92, the force of the spring I94 will be overcome and, hence, the retaining element I93 will be ineffective.

In the coursaof downward movement of the printing" element i90, the position of the printing element is re'versedfas will'be evident by compari's'on of the two iJQsitions of this printing element as shown in Fig. 2; so that as the printing element approaches its lowermost position it is located in a downwardly facing relationship Whereinit may effect the desired printing operation on th'epos'ti-ng area Iiof the card 0. in accomplishing such reversal of the position of the printing element I90, the printing element is supported on a mounting block W8 that is generally L-shaped in form, and this mounting block I93 has aligned shafts I99 extended from opposite ends thereof along an axis that is parallel to the printing fa'ceof the printing element I90. These shafts have reduced ends 199A thatare associated with the left-hand end, Fig. 2, of the rocker I80 50 that th'e'printing element may be raised and lowered by the rocker I80, and. the reduced ends I99A are also extended outwardly through generally arcuate guide slots 200 formed in the side walls I10 and Ill respectively of the housing sothat the shafts I99 are guidedvb'y such slots 290 as the printing element I90 is raised and lowered. The rocker I 88, as ,herein shown, is so formed as to afford spaced arms IBBA that are disposed adjacent to the side walls of the housing where the slots 200 are formed in these side walls, and the arms I80A of the rocker I80 have slots 29I formed therein so as to extend longitudinally of such arms The slots 20 I 7 embrace the reduced end portions I9';9A of the shafts I99, thereby to form the desired connection whereby the rocker net is effective toiiaijse and lower the printing element I90, and nuts.v 2104.are disposed on these shafts just inwardly, of the arms I80A so .as to effectually separate and guide these arms. Thus,

Fig. 2.

it will be clear that when the rocker I 80 is moved in a counter-clockwise direction from the position shown in Fig. 2, the shafts I99 will be moved I99 will first be moved in a downward and right-' hand direction, and will then be moved in a downward and left-hand direction and then into vertical portions of the slots 200 until the shafts I99 reach the dotted line position shown in Fig.

2, and this path of movement of the shafts I99 is utilized in obtaining reversal of position of the printing element I90. Thus, as will be evident in Figs. 2 and 3 of the drawings, the mounting block I90 has a slide rod 2I0 extended therefrom so that it projects downwardly from the block I98 when the block is in its upper position of Figs. 8 and 9. This slide rod 2 I0 extends downwardly through a transverse bore 2 in a rocking bar 2 I2 that is supported on a fixed horizontal axis halfway between the upper and lower positions that may be assumed by the shafts I99. The mounting for the rocking bar 2 I2 in the present instance isattained in such a way as to afford clearance for the arms I80 and the ends [99A of the mechanism as these elements move through their operating strokes. Thus, a pair of supporting brackets 2I5 are provided, and one of these brackets is mounted in a fixed position on each of these side walls I10 and IN. The mounting brackets are generally U-shaped in form, and one arm thereof is held in position against the outer face of the side plate by rivets 2I6, this arm of the member being bent outwardly at 2 I1 to afford clearance forthe adjacent end I99A of the shaft I99 that projects through theguide slot 200. At the rear or left-hand ends, Fig. 2, of the brackets 2I5, the material is bent in an inward direction and is then bent in a forward direction so that the other or inner arm 2I5A of the U-shaped bracket extends in a forward direction. The arrangement is such that the inner arm 2I5A of each bracket H5 is spaced from the sidewall upon which it is mounted in an amount sufiicient to afford clearance between the side wall and the arm 2I5A for the arm I80A of the rocker I90.

The inner arms 2 I 5A of the brackets are utilized to afford a pivotal or rocking mounting for the rocker bar 2i 2, and this is accomplished in the present instance by aligned pivot pins 2I8 that extend from opposite ends of the rocking bar 2 I2 andthrough the adjacent arms 2 ISA of the brackets 2| 5.

With the-arrangement thus described, it will be apparent that the downward movement of the shafts I99 along the path determined by the guide slots 200 serves not only to slide the rod 2I9 through its bearing 2 I I, but also serves to rotate the rocking bar 2|2 about the horizontal axis afforded by the pivot pins 2 I8. Hence, when the rocker I80 has moved through substantially onehalf of its. counter-clockwise rocking stroke from the position shown in Fig. 2, the slide rod 2 I0 will be located in a substantially horizontal position, and the printing element I90 will be faced in a forward or right-hand direction as viewed in Continued downward movement of the shafts I99 serves to complete the reversal of position of the printing element I90 so that when'the shafts I99 reach the lower limit of their travel, the printing element I90 will be disposed in the downwardly facing position shown in dotted outline in Fig. 2, and it is while the printing element is in this position that the desired impression is made on the card C. Upon reversal of movement of the rocker I80, the position of the printing ele-- ment I90 is again reversed and the printing ele-' ment is brought into its upper or rest position in' engagement with the ink pad I9I.

It has been pointed out hereinbefore that the printed impression 22 that is made upon the card C by the posting unit is formed in a particular one of the spaces I1 of the card in accordance with the location of the posting unit 80 with respect to the operating position in which the card 0 is located by the stop finger I60, and in accordance with the present invention, the posting unit 80 may readily be set or located on the table top T of the machine so as to attain the desired location of the printed impression 22 on the card C. In attaining this result, the posting unit has a pair of fastening bolts 220 extended downwardly through the top wall I14, and the re-' duced lower ends of the bolts 220, as indicated at 22I in Fig. 2, are extended through openings formed in the base plate I13 of the posting unit. The shoulders formed on the fastening bolts 220 above the reduced portions 22I thereof are arranged to seat against the upper face of the base plate I13 and the screw threaded lower ends of the reduced portions 22I are adapted to be threaded into selected screw threaded openings 224 that are formed in amounting plate 225 that-is secured on the table top T of the machine. In forming and locating the threaded mounted openings 224 in the mounting plate 225, the arrangement or disposal of these openings 224 is correlated with the arrangement in which the printed impressions are to be placed.

It will be observed inFigs. l and 2 of the drawings that rearwardly of the base plate I13, the lower edges of the side plates I10 and HI are offset upwardly as at 228, thereby to assure adequate clearance between these plates and the surface of the table top T. It should also be observed that in the course of adjusting move- I ment of the posting unit 80 in a front to rear direction, the operator must avoid the making of impressions directly over the belt 38, and hence, after the posting unit has been adjusted to a particular relationship, the belt 38 may be disposed in a lateral position wherein it will be spaced substantially from the location at which the impression is to be made by the printing element I90. Proper clearance for such adjustment of the belt 38 is afforded by the slot 61 in the lower edge of the stop finger plate 0|,and it will be recognized, of course, that the pressure rollers 13 will in such an instance be adjusted to proper positions laterally of the guideway G by the adjusting mechanism 229 that is indicated generally in Fig. 1 of the drawings.

From the foregoing description it will be evident that the present invention affords an improved posting unit adapted particularly for use in an automatic v record posting machine, andthat such posting unit is capable of operation in such a machine in an improved, highly advantageous manner.

Thus, while I have illustrated and described the preferred embodiment of my invention, it is to be understood that this is capable of variation and modification, and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
