ATTORNEY Patented Feb. 6, 1940 UNITED STATES PATENT OFFICE I PRINTING MECHANISM FOR TABULATING MACHINES Original application March 22, 1929. Serial No. 349,080. Divided and this application July 10,

1938, Serial No. 89,943

10 Claims. (01. 101-93) This application is a divisional application 01' the parent application Serial No. 349,080 now issued as Patent No. 2,047,519 dated July 14, 1938.

The parent applicationdiscloses and claims an improved arrangement for translating combinationai hole punchings oi a record card for the purposes set forth in the parent application. The record card disclosed in the parent application and in this application is punched with two lines of data, in an upper and lower deck fashion.

The present application is devotedsolely to the disclosure oi. such combinational hole punchings for representing both numerical and alphabet data and discloses how the translator of such combinations] hole punchings can control the selection of type for printing numerals and alphabet data.

It is a broad object of the present invention to devise a system for designating two or more horizontal lines of data on a single record card and 'to cause said record to control type printing mechanism so as to print the two lines of data on a single printing line of a data receiving sheet.

In record controlled alphabet type printing mechanism of the type heretofore constructed a single card column has been utilized for the representation oi each letter so that no apparent diillcultyv has been experienced to print on a single line the data represented by the record.

The present invention doubles the data representing capacity by punching, preferably in the form of a code, and renders it possible to print the two lines of data represented by the code punchings in the upper and lower part oi the card on a single line.

A more specific object 01 the present invention is to devise a type carrying bar so that'it may be provided with two groups of type, and to translate combinational hole designations so as to select a desired group of type and a type in the selected group. I

n The invention has preferably been shown in connection with the Powers type of machine in which a member carries two groups of type, one of which is selected by the release of a latch. This latch effects the connection between the member carrying the type and a control member and when the latch is disabled a relative movement between the members is effected which causes the selection of the second group of type.

A further object of the present invention is to devise an arrangement for controlling the alphabet type printing mechanism of the Powers type oi machine so that the groups of type may be selected under control of electrical instrumentalities.

In the preferred embodiment such instrumentalities comprise electromagnets of which there is one provided for each alphabet type printing column. The translator is adapted to eflect the energization of the magnet at a predetermined point in the cycle of machine operation so as to select one or the tabulator stops which is operative to select a desired type. The selection of the groups may be effected, in the preferred embodiment, by one energization of the same electromagnet which efiects type selection and is energized when a special punching is provided for selecting the other group of type. This energization of the electromagnet effects the operation of the aforementioned latch to select as has been previously explained the second group of type.

A still further object of the present invention is to provide an improved form oi connection box and preferably of the electrical type, so as to efiect the control of the alphabet type selecting magnets under control of pins which are responsive to the sensing oi the perforations.

A more specific object of the present invention is to devise a system 01 combinational codei punchings whereby pins of the well known form of sensing head of the Powers tabulator may respond to the presence of such perforations and to cause said pins to raise what is designated herein as contactor bars. These bars are, therefore, raised in response to the code punching and are subsequently correlated with contact carrying plates carrying contactors arranged in combinational form. I his will effect a translation of the combinations] code punching and, as has been subsequently explained will control the operation of a suitable alphabet printing mechanism.

Another object of the present invention is to provide a single set of permutation contacts which are operative for the selection of type in two different groups and to cause the same mem bers which carry the permutation contacts to effect the selection of one of the groups of type, whereby the permutation contacts will be operated for the selection of type in this group.

While the invention has been shown in connection with a tabulator of the well known Powers type it should be understood that the disclosure is merely illustrative rather than restrictive. It will be apparent that many of the novel constructions and arrangement of parts may be applied to other forms of tabulating machines and it is the desire not to restrict the invention to the embodiment disclosed herein.

With these and otherobjects in view as will be apparent as the specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described'and pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Fig. 1 is a vertical sectional view showing the means for reading the data from the record cards and the improved means for alphabetical control.

Fig. la is a view in side elevation of a well known form of alphabet printer for the Powers tabulator.

Fig. 2 is a view showing the side elevation of all of the contact parts of a section and indicating graphically by zones how' they combine for alphabetical control.

Fig. 3 is a fragment of a record card showing the numerical and alphabetical code punching.

Fig. 4 is an end view of the commutator.

Fig. 5 is a diagrammatic representation of a representative circuit.

Fig. 8 is a view similar to Fig. 7 but shows the manner in which one of the contactor bars of a set of six is modified with respect to the other contactor bars. I

Like characters of reference refer to like parts in all views.

Referring to the drawings, in detail, and in particular to Fig. 1, represents the tabulatorpin-guide plate of the well known construction, familiar in the commercial field as the Powers tabulator; and M represents the tabulator pins guided by said plate. In the machine as at present constituted and commercially known, there are twelve pins 2| in each column.

It will be recalled from the known Powers tabulator as commercially on the market, that wherever a perforation occurs in the data card, a pin 2I will be raised in the event that there is a perforation and during the cycle of operation in which the card is passed through the machine. But in the known structure only one series or line of data is read from each data card, whereas in the present invention it is necessary to provide means for sensing two series or two lines of data and conducting the sensed data from each series to a diiferent portion of the tabulator head so as to print the two lines of data on a single printing line. Such means is provided and will now be set forth.

It is at times necessary to devote a portion of the tabulator to the printing of alphabetical or symbolic matter, and in the Powers tabulator as at present constituted and disclosed in Fig. 1a

(taken from the patent to Lasker No. 1,624,956, dated April 19, 1927), an alphabetical sector is used comprising two parts, one of which is a print sector II carrying two groups of type l3 and the other a control sector I 2. A relative movement of the two sectors is effected by releasing the latch flf in said patent and is released by a perforation in the card controlling the zero stop 22 of the series of stops 22, or the release finger of said patent. In the present instance, a perforation in the "3 position or in the "9 position controls means for operating the zero stop 220 so as to release said latch I 0. This will permit print sector I I to move relative to the control sector I2 in order that the second group of type I3 of the alphabetical print sector can be selected.

The alphabetical arrangement disclosed in said Lasker Patent No. 1,624,956 and used in the standard Powers alphabetical tabulators is conline by the tabulator of the present invention. K

desirable alphabetical code punching is shown in Fig. 3 but this can be varied according to requirements using the well known six point combinational code. The specific control mechanism for alphabetical work is best shown in Figs. '1, 2, 4, 5 6, 7 and 8 and is constructed as follows:

On the edge of the lower guide plate 20 for the pins 2I there have been placed in Fig. 1 the numerals 0" to "12" inclusive, indicating the values of the pins 2I in the Powers machine as at present on the market. Directly over the pins 2| are respective contactor bars. which are indicated respectively as 308, 301, 308, 309, SID, 3, 306A, 301A, 308A, 309A, SIOA, and 3| IA, the first six bars at the right beingraisable by thepins co-operative with the upper half of the record card and the second six bars at the left by the pins cooperative with the lower half of the record the other of which the contactor bar will stand according to whether its pin 2I is raised or lowered. It will be remembered that a perforation in a record card permits, raising of'the' respective pln 2I and; consequently in' the present construction will result in the raising of the respective contactor bar. It will be understood, of course, that there is one series of twelve contactor bars for each column of analyzing pins 2|, the several series being du licates of each other. 7

Universal rods 24. 25. 26 and 21 are supported and guided in slots 28 in the framework 29. Rods 24, 25. 26, and 21 are either made of insulating material or are suitably insulatedfrom parts with which they cooperate. Secured to rods 24, 25, 26 and 21 and movable therewith are a plurality of vertically disposed carriers or tie and spacing members 30 and 3| preferably made of insulating material, members 30 extending over the rod 24 for a purpose to be presently set forth. Mounted on the rods fl, 25, 26, and 21 are two series of contact carrier plates one series above the other. Each series of contact carrier plates consists of six thin contact plates insulated from at "0A, "IA, 302A, 303A, 304A and 305A, the

plates 300 and 305 of the upper series and 300A and 305A of the lower series being the outer plates of these series.

Each of the contactor bars 305,301, 300, 300, and 3l0, carries (see- Fig. 7) an upper laterally extending contactor or brush 204 and a lower laterally extending contactor or brush 205 and each of the contactor bars 306A, 301A, 308A, 309A, and 3IOA carries an upper laterally extending contactor or brush 204A and a lower laterally extending contactor or'brush 205A. The contactor bar 311 is provided only with a lower laterally extending contactor or brush 205 (see Fig. 8) and the contact bar MM is provided with a lower laterally extending contactor brush 205A, as their only function is to bridge directly across from plate 300 to 305 or from 300A to 305A whenever a punch occurs in the 3" or "9 position. The several brushes 204, 205 and 204A and 205A are insulated from their supporting contactor bars.

The purpose of these series of contact carrier plates will be now considered, bearing in mind that-those having an A as part of the reference characters are co-operative with those contactor bars having an A as part of the reference characters. Current is conducted to the contact carrier plate 305 or 305A at one side of each series of plates by any desired means such as spring brushes 213 and 2I3A (Fig. 1), and brushes 214 and 2I4A contacting the contact carrier plates 300 and 300A at the other side of the series are provided with connections (later fully described) leading to desired electro-magnets 230. Thus when a circuit is completed through the contact carrier plates of any series the correlated magnet or magnets 230 are operated at the time of completing such circuit. An electro-magnet 230 is provided for controlling each column of the tabulator head. The means by which the contact carrier plates are connected at the proper instant includes contacts on the carrier plates and the brushes 204 and 205 and/or 204A and 205A. This means of connection will now be described.

As shown inFig. 2 the plates 300-305 and 300A-305A are formed with upper contact fingers 215 and lower contact fingers 216; and the six plates of a series held between plates 211 of insulating material are of suflicient breadth to permit exposure of the ends only of the fingers 215 and 2| 5 to the wiping action of the brushes 204, 205, 204A, and 205A. Normally, the brushes 204, 205, 204A and 205A are all down, so that the brushes 204 and 204A are in position to contact the several contact fingers 2l5 as they are moved across the brushes. But if any of the bars 306 to 3 and 306A to 3 is raised, then its brush 204 or 204A is raised out of effective relation to the contact fingers 215, and its brush 205 and 205A is raised into effective relation to the contact fingers 215.

It may bewell at this point to consider Fig. 2 somewhat more indetail. It will be noted that the contact carrier plates have been divided into zones by vertical lines, the zones being indicated by the letters A to N and X to Z merely for designation purposes and should not be confused with the alphabet type which are selected by the contact carrier plates. The width of a zone is the distance between the centers of the contactor bars 300 to- 305 or 300A to 305A. The contact fingers 2l5 and 2| 6 within these various zones have subscripts with the letter of that zone. These contact fingers have been so arranged that for each of the above described code punchings of the card there will be only one position at which the circuit will be closed throughthe six contact bars and that position will be such that the operation of the correlated magnet 230 will control the parts of the machine according to such code punching. The contact carrier plates 300-305 have been shown here as identical with contact carrier plates 300A-305A which is correct as far as the relation of the contact fingers is concerned but, of course, the contact carrier plates themselves are made with the entire series of contact fingers arranged to coact with the respective brushes.

Considering now the means for causing contact plates 308-3 and 308A-3HA to traverse the brushes 204-205 and 204A-205A, 31 (Fig. 1) represents a rotating drive shaft of the tabulator. Upon the end of this shaft 31 is pinned a disk 38 carrying a laterally extending pin 30 which rides in a slot 40 formed in a rocker 4| pivoted at 42 and connected by a link 43 to one end of an arm 44, the other end of which is fast on a rock-shaft 45. This rock shaft 45 carries a pair of depending arms 46 to which are pivoted links 41 formed with slots 43 through which the rod 25 extends. Springs 49 anchored at one end to the links 41 and at the other to the-rod 25 tend to constantly hold such rod in the left-hand ends of slots 41 as viewed in Fig. 1.

It will now be apparent that rotation of shaft 31 will cause rotation of disk 30 which will cause pin 39 to effect rocking of rocker 4|, whereby link 43 will be caused to rock arm 44, shaft 45 and depending arms 40. This causes reciprocation of links 41 and rod 25. Rods 24, 25, and 21 together with the tie and spacing members 30 and 3| and the several series of contact carrier plates form a unit so that reciprocation of rod 23 effects reciprocation of all of the contact carrier plates so as to traverse the several brushes 2l3, 214, 2I3A and 2I4A.

Turning next to the circuits (see Fig. 5) closed by the completing of the connection from one outside plate to the other of any series of contact plates 300-305 and 300A-305A, a suitable source of electric energy is indicated at 50 from which current is passed over a lead 5| to a brush 52 which contacts a rotary commutator body 53 mounted on shaft 31- for rotation thereby and having a contact strip 54. A second brush 55 also contacts the periphery of commutator 53 and is connected by a lead 55 and branches thereof to the several spring brushes 2i 3, 213A. Brushes 2l3, 2l3A, 2l4 and 214A are supported on through rods 51, and while the rods 51 of brushes 2! 3, 2| 3A need not be of insulating material, the rods 51 of brushes 214, 2I4A must be of insulating material or suitably insulated from the brushes mounted thereon. Each brush 254, M411 is connected bya respective lead 58 to a respective metal cross rod .59 of the connection box 60; and each cross rod 59 may be connected by means of metal sliding connectors 62 toany one of a plurality of vertical metal strips 63. The connection box 60 is fully described in my Patent No. 2,063,118, dated December 8, 1936.

The slides 62 are provided with fingerpieces By the proper selective connections the upper line of data on the card of Fig. 3 is sensed to control a series of printing control magnets 230 to print the data on a line and by proper selective connections the lower line of data on the card of Fig. 3 is sensed to control a series of printing control magnets 230 to print this data on the same printing line.

While only shown for two magnets 230 each of the vertical strips 63 is connected to one side of a magnet 230 by a lead 65. The other sides of all of the magnets 230 are grounded to a lead 61 back to the source 50.

In order to hold the several magnets 230 energized after the same have been energized and during such portion of cycle as is necessary; even though the line contacts 2I5 and 2I5 may have passed out of circuit closing position, there is provided what is known as holding circuits for these magnets. A third brush 68 contacts the commutator disk 53, and a portion of the contact strip 54 is notched at 69 so that this brushwill not contact strip 54 until shortly after brushes 52 and 55. This brush 68 is connected by a lead 10 and branches to the armature 23I of each and every magnet 230. The positive or inlet side of each magnet 230 is connected to a respective contact 12 positioned to be en- 7 gaged by the armature 23I of the respective magnet when in closed position. Hence when once the armature of a magnet 230 is closed it will be held closed by the circuit from 50 through 52, 54, 68, 10, 23I, 12, magnet 230 and to 61, until this circuit is broken by the rotation of commutator disk 53 sufliciently to bring contact strip 54 out of engagement with brushes 52 and 68. During this time the mechanism of the tabulator head has completed its recording of the required alphabet characters.

With contactor bars 3063II and 306A--3I IA I see Fig. l) have been raised means are provided for locking raised bars in raised position and unraised bars in normal position. For this purpose. each of these contactor bars is provided with an upper notch 13 and a lower notch 14. The upwardly extending portions of members 30 hereinbefore mentioned, normally contact a cross rod I5 and hold it to the right in Fig. 1 against the tension of springs 16. This rod 15 together with another rod I1 and a plurality of cross strips 18 form a locking frame. This looking frame is supported and guided by projecting the ends of rods 15 and 11 through short slots in the framework. Each cross strip I8 is provided with lateral pins 19 for engagement with the notches 13 or 14 of the bars 306-3 and 306A.-3IIA. Preferably there is only one bar I8 for each two rows of bars 306-3I I and 306A- 3| IA, the pins 18 projecting on both sides of bars 18 so as to coact with the adjacent bars 306--3I I and 30BA-3IIA on each side of each bar 18. As soon as the members 30 start their excursion toward the left in Fig. 1, the locking frame is permitted to follow up until its pins 15 engage the notches 13 of all lowered bars and the notches suitable manner, there being one bar 84 for each row of stops 22. The bars 84 are positioned directly beneath the respective rows of stops 22.

Slidably mounted on each bar 84 is a slider 880. To the slider 880 there is secured a spring 82 anchored to any suitable stationary part such as rod 98, and tends constantly to draw the sliders 880 to the right as seen in Fig. 1.

The magnets 230 are provided with the armatures 23I each of which is connected by a link 232 so timed that when one of the magnets 230 is operated by the bridging of the contacts 2I6X, see Fig. 2 (i. e., where there is a perforation in the 3 or "9 position) the brush 58 will be in the notched out portion 69 (Fig. 4) of the commutator and consequently this magnet will be operated and then let go as its holding circuit will not have been closed by contact of brush 68 with the contact strip 54. The vertically movable bar 231 connected with this particular magnet will, therefore, be raised and then lowered by a spring 2318,

, which will set mechanism for operating the zero stop 22 for releasing the alphabetical sector, which mechanism will now be set forth. 7

In that unit of the mechanism devoted to alphabetical work each of the sliders 880 mounted on the rails 84 is formed in a single piece having ears. 240 slidably securing the respective slider 880 ffto the respective rail 84 and formed with teeth -80 and with an upwardly extending finger 24I' carrying a pin 242 extending through a slot 243 in the depending finger 244 of a slider 245 mounted on a respective rail H2. The rails I I2 are pivoted at one end on the stationary rod H3 and at the other end are-connected to the universal bar II4 which merely rests on some stationary part of the machine to thus hold the bar I I4 and rails I I2 upwardly. The slider 245 is formed-with ears 246 embracing and'slidably securing the slide 245 to the rail I I2, and carries a stop-lifting finger 241. Also mounted on each rail II2 isa second slider 248 provided with ears 248 which embrace the rail I I2 in such manner that the slider 248 is slidable along the rail and cross-wise of the rail so as to render its stop-raising finger 250 effective for raising the zero stop 22 of the tabulator. The slider 248 is provided with an upwardly projecting hook element 25I which is adapted to engage and hook into a retaining ledge 252 formed on a member 253 carried by the guide plate 254 of the pins.

therefore, tends constantly to pull the slider 248 toward the right in Fig, 1 and also to keep the free end of the slider down incontact with its rail H2. The connected fingers 24I and 244, of

sliders 880 and 245 contact rod I05, and slider 245 engages the upstanding spring finger 255 to hold the slider 248 normally to the left. Rod I05 forms' part .of a frame having sidebars I06 and a cross tie rod I01 which frame is reciprocated at each cycle of the machine by links I08 pivotally connected to I05 and at I08 to upper arms II0 secured to and rocked by shaft45. The frame I05, I06, I01 is supported and guided by extending bar I05 into slots 400 in the frame work and by forming the members I05 L-shaped and extending studs Ill throiigh, parallel with I01, and in-thesamehorizontal plane as I05, so theymay somewhatextended ride in the same slots 430.

Wh'en,*however, a punch occurs in -a position tooth 90, and being held so as to maintain finger 241 under the proper stop 22. Of course where there are double punchings, both the stop 250 and stop 241 will be brought to operative positions and will raise respective stops 22 when the universal bar 4 is raised. In order to rock the frame comprising the bar H4 and rails I I2 so as to effect raising of all the desired stops 22, the outer member H2 is provided with a roller I30 (Fig. 1)

which is engaged and raised by a cam portion or lug "I on member I when it nears the end of 252. It will be remembered that the holding circult is not eiiective at this time, and consequently bar 231 drops back to lowered condition by spring 2310 before any tooth 30 arrives at pin 233. The operation progresses and at some point in the travel of slides 000 and 245, depending on the secondary aperture or apertures of the combinational punchings, the member 231 is again operated, stopping these slides with finger 241 under the desired pin 22. After the several fingers 241 and 250 are set, bar 4 is raised as in Fig. 1 and in any column where both fingers 241 and 250 are active the "0 pin and one of the other pins will be raised with consequent control of the tabulator head as is well known'in the art. Thus means are provided for both numerical and alphabetical work.

To more fullyunderstand the operation of the machine, two examples will nowbe given, one explaining the operation for selecting the type "c" in the first group of type and also the operation for'selecting a type r? in the second group of type.

For the selection of the-type "e for the upper line of data, the record card shown in Fig. 3 is provided with holes at the "1 and 2" index point positions and from Fig. 1, it will be seen that this will cause the elevation of the contactor bars 309 and 310. When the series of contact carrier plates 300 to 305 is moved in the arrow direction shown in Fig, 2, the contact fingers in the zones H, I, J, K, L, and M will be, correlated with the contactor bars 3| I, 310, 303, 300, 301 and 305 respectively. The contactor bar 3 is ineffective in the selection of thetype in first group. The raised contactor bars'303 and 310 and the unraised contactor bars 3, 303, 301, 300 will close a circuit by means of their brushes 204 and 205 through their correlation with the contact fingers of the contact plates to thereby close a circuit to a print control magnet 230 at a predetermined point in the cycle of machine operation. This circuit is outlined in Fig. 2 by the line designated e-e and is described as follows: from the brush 2|3, (Fig. 2), contact plate 305, contact finger 2161 of the contact plate 305, lower con tactor brush 205 of the raised contactor bar M0,

the contact finger 2l61 of the contact plate 304, contact plate 304, contact finger 2l5m engaged by the upper contactor brush 204 of the unraised contactor bar 306, contactor bar 306, contact finger 2i5m of the contact plate 303, contact plate 303, contact point 2151 of the contact plate 303, upper contactor brush204 of the unraised contactor bar 301, contact finger 2|5i of the contact plate 302, contact plate 302, the contactor brush 20. of the unraised contactor bar 308, the contact finger 2l5 k of the contact plate 30!, contact plate 30l, the contact finger 2 I6 engaged by the lower contactor brush 205 of the raised contactor bar 309,

the contact finger 216 of the contact plate 300,

contact plate 300, to the brush 2 14 (Fig. 5) which extends the circuit to the print control magnet 230.

As previously stated the print control magnet 230 is energized at a predetermined point in the cycle of machine operation so that the stop-lifting finger 241 will be correlated with the 2 tabulator stop of the series 22. The stop-lifting finger 241 is, as previously stated, elevated so as to raise the selected stop to thereby control the positioning of the print sector II to thereby select for a printing operation the type e.

For the selection of the type r it will be seen from the code shown in Fig. 3 that the perfora-' tions are also provided at the index point positions fl and 2 as for the selection of the type e and, furthermore, a supplemental perforation is provided at the 3 index point position. This will, as shown in Fig. 1, cause the elevation of the contactor bar 31 I to thereby cause the raising of the lower contactor brush 205 from the position shown in Fig, 8. The latter, as will be seen from Fig. 2, will bridge the contact fingers 216:: to thereby close a circuit across plates 300 and 305 which, as previously stated, will cause the initial or first energization of the magnet 230 to cause the subsequent raising of the zero stop 22. As previously described, this will permit a relative positioning between the print sector II and the control'sector I2 so that the second group of type carried by the print sector I I is selected for operation.

The selection of the particular type in the sec-- ond group is effected in the same manner as described for the selection of the type e" so that the type r is selected for printing operation. The circuits for the selection of the other type in both groups is effected in a similar manner, and it is thought, therefore,- that further description is unnecessary. In all cases the contact fingers are so arranged as to effect the selection of the type carried by the print sector l3.

While I have described what I-consider to be the most desirable embodiment of my invention, it is obvious that many changes could be made without departing from the spirit of my invention, and I, therefore, do not limit myself to the exact construction shown nor to anything less than the whole of my invention as hereinbefore described, and as hereinafter claimed.

I claim:

' 1.
