00 zYXwv uT ORQPONMLKJ H FEDCBA bination of Patented Mar. 21, 1933 UNITED STATES PATENT OFFICE PETER DECHENE, 0F BERLIN, GERMANY, ASSIGNOR TO THE TABULATING MACHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION OF NEW JERSEY PRINTING MECHANISM Application filed November 27, 1929, Serial No. 410,127, and in Germany December 18, 1928.

This invention relates to record card controlled machines and more particularly to the printing mechanism of such a machine in which alphabetical printing is desired.

It is the objectof this invention therefore to provide means for selecting groups of printing elements and single printing elements within said groups by means of a single element.

I Various other objects and advantages of my invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings; and the invention also constitutes certain new and novel features of construction and comparts hereinafter set forth and claimed:

In the drawings:

Fig. 1 is a detailed elevation of type selecting and printing mechanism.

Fi 2 is the same as Fig. 1 shown in the position of selecting a type element for print- Tig. 3 is a tabulation showing the letter groups and the index positions associated therewith.

Fig. 4 shows a portion of a record card punched to spell a word.

This printing mechanism may be substituted for or used in part with the printing mechanism shown and described in the application of C. D. Lake, Serial No. 639,153, filed May 13, 1923, now Patent No. 1,822,594. As this invention only concerns the printing and selection of the printing elements, the card feed, brush sensing mechanisms and controls have not been shown, they being the same as described in the Lake application mentioned above. The impulses transmitted from the sensing brushes by virtue of perforations in the cards passing the brushes effects the printing magnets to select the proper notch 1n the type bar carrier in the same manner and thereforefor the sake of simplicity the type bar carrier and coacting selecting mechanisms only are shown.

In the preferred forin of embodiment there may be provided a cross head 10 which is moved upwardly in timed relation to the passage of record cards beneath sensing brushes, not shown, situated in another part of the machine. As the method of card feed and the use of sensing brushes is generally known and fully described in the application to Lake previously mentioned and per se form no part of the present invention, it is deemed unnecessary to illustrate or explain them in detail. A comb 11 fixed to the cross head 10 has slidably mounted therein a plurality of type carrier members 12. Abutting the end of each of these members is a lever 13 pivoted to a bracket 14 fixed to the cross head. The lever 13 is biased upwardly by the spring 15 so that when the cross head rises the members are raised by spring pulled lever 13 until such time as the locking pawl 16 engages one of the teeth 17 integral. with the. member 12 at which time the member 12 is halted and the continued. rising of the cross head causes the lever 13 to yield through the resiliency of the spring 15. Integral with the upper end of the member 12 is a rack 18 which meshes with a gear 19 pivoted at 20 to a lever 21 said lever being pivotally mounted at 22 to a bar fixed to the frame of the machine (not shown). The lever 21 is biased by a spring 23 in a clockwise direction about its pivot 22 to normally hold the gear 19 in mesh with the rack 18. Fixed to the gear 19 is a disk 24 having on its periphery raised alphabetical ty e indicia 25. As the number 12 rises the dis 24 rotates in a clockwise direction and the teeth 17 pass the locking pawl in synchronism with the passage of the index point positions of the card under the sensing brushes in another part of the machine. Thus when the sensing brush encounters a perforation it releases the pawl coacting with its corresponding type carrier member to engage the notch corresponding to that particular index point position. Thus, for example, if a card is perforatedinthe fifth index point position of the column corresponding to the mechanism shown in Figs. 1 and 2, the member 12 will rise-in synchronism with the travel of the card and as the sensing brush encounters the perforation at the fifth index point position the fifth notch 17 will be opposite the locking pawl 16 and the magnet 27* will receive an electric impulse by virtue of the contact made by the sensing brush through said perforation.

Said impuse energizes magnet 27 and releases the locking pawl to engage the notch 17, and the mechanism is timed to bring the E type indicia into printing position when; the member 17 reaches its final locked position prior to the printing operation.

It will be noticed that the alphabet is divided into three groups AI, JR, SZ (Fig. 3) these groups being assigned to the index point positions 1-9 inclusive, column 28 (Fig. 3) representing the index point positions relative to the alphabet. Thus the index point position 9 may designate either of the three letters A, J, S or the position 8 may designate either of the letters B, K. T, and so on as clearly shown in Fig. 3. The alphabetical type therefore is placed around the periphery of the disk 24 ina corresponding manner, thus A, J, S, B, K, T, C, L, U, etc. as shown in Fig. 1. The selection of one of the three letters for a given index point position is determined by the presence or absence of perforations at the 0 index point position or at both the O and 11 index point positions If a perforation appears at the 6 index hole position only in a column the letter D will be printed; if at the 6 and 0 index point posi-' tions, the letter M will be printed; and if in 1 addition to the perforations in the two positions ust mentioned there is a third perforation encountered at the 11 index point position, the letter V will be printed. Fig. 4 illustrates how a card may be perforated to spell the Word Hot which is made up of three letters, one from each group. Although the the 0 or 11 index point position in the preferred embodiment described herein, it will be understood that these holes may follow the primary selection or first hole at any position following the same.

The locking of the member 17 in the proper' position to cause a designated letter to be printed is accomplished by the pawl 16 which is pivotally mounted atc28 to a lever 29 and is biased in a clockwise direction by the spring 30. The lever 29 is pivotally mounted on a rod 31 which extends across the printing bank of the machine, said lever being normally held in the position shown in Fig. 1 by the action of the spring 32 fastened to said lever at one end and to the frame of the machine (not shown) at the other.

A latch 33 pivoted at 34 supports the arm 16 of the locking pawl 16 normally holding it out of contact with the notches on the member 17. A link 35 pivotally connects the latch 33 with an armature lever 36, said lever being pivotally mounted at 37 to the frame of the machine. A. spring 38 biases the armature lever 36 in a clockwise direction thereby normally holding the armature away from its coacting electromagnet 27 and holding the latch 33 in latching position. Pivotally mounted to the link 35 is a pawl 38 coacting with ratchet teeth 39 on the peripheryof a disk 40, said pawl being held in coacting relationship with said ratchet teeth by means of the spring 41. The disk 40 is rotatably mounted on a rod 42 which is supported by the frame of the machine (not shown). The disk 40 is biased in a clockwise direction by a coiled spring 43, one end of which is fixed to said disk and the other end to the rod 42. In addition to the ratchet te'eth 39, the disk 40 has provided on its periphery a second series of ratchet teeth 44 and three position steps 45, 46 and 47 with which the lever 29 coacts to position the proper type element for printing. A pawl 48., pivoted at 49 and biased in a counterclockwise direction by spring 50 coacts with the ratchet teeth 44. The end of the pawl 48 is fastened by a pin and slot connection to a link 51 the other end of said link being pivotally fastened to an armature lever 52, pivoted at 53 and coacting with an electromagnet 54. Said armature lever 52 is resiliently held away from its coacting magnet 54 by a spring 55. Fixed to the link 51 is a pin 56 which coacts with the pawl 38 to withdraw it from the ratchet teeth 39 when the magnet 56 is energized.

In the description of the operation of this mechanism let'it be assumed that the letter Wis. to be printed in which case the mechanism will take the position shown in Fig. 2. This will require a perforation at the 5 index point position on the card, one at the 0 index "point position andone at the 11 index point position, all in thejsame column. second and thlrd control holes are shown in 1 As the card passes under the sensmg brush, the members 17 will rise in synchronism therewith so that when the perforation at the 5 index point position is under the brush, the stop pawl 16 will be opposite the 5th notch 17 When the brush encounters the perforation an impulse is sent through the corresponding printing magnet 27 attracting its coacting armature lever 36 and Withdrawing the latch 33 so that the locking pawl 16 turns clockwise about its pivot and engages the notch 17, then opposite said awl. the armature lever 36 is attracte by the magnet 27 the link 35 is moved to the right carrying the pawl 38 which is engaged in the ratchet teeth 39. This action rotates disk 40 in a counterclockwise direction so that the stop pawl 48 engages .the next succeeding right hand ratchet tooth 44 and holds the disk in this new position. The member 17 now engaged by the locking pawl 16 continues to move upwardly and causes the lever 29 to be rotated clockwise about its pivot 31 until said lever abuts the stop position 45 on the periphery of the disk 40 at which time the upward motion of the member 17 is halted bringing the type E into printing position.

When 1 The cross head 10 continues up while the lever 13 yields under the influence of spring 15. As the card continues under the brush the perforation at the 0 index point position causes another impulse to be sent through magnet 27, the energization of which causes the disk 40 to be advanced another notch in a counterclockwise direction presenting the stop position 46 to the contacting point ofthe lever 46. Said lever being now unsupported, the member 17 will move upward again under the influence of the spring 15 and will turn the lever 29 counterclockwise until it abuts the stop position 46 at which point the type elements will be brought to rest with the letter N in printing position. Following this, the perforation at the 11 index point position causes a third impulse to be sent through the magnet 27 which advances the disk 40 another notch and presents the stop position 47 to the contact point of lever 29 so that the member 17 rises slightly further turning the lever 29 until it rests on said stop position 47, which moves the type element W into printing position.

It will be seen therefore that with the first perforation only existing in the column, the letter E will be stopped in printing position; with the first and second perforations only the letter N will be stopped in printing position, while the three perforations mentioned are required to present the letter W for printlng.

When the cross head 10 reaches the top of its stroke printing is effected in a manner to be described later. As the cross head descends a contact (not shown) is closed which completes a circuit through magnet 54 thus energizing said magnet and attracting its armature lever 52, moving it clockwise about its pivot 53 and drawing the link 51 downwardly. The pin '56 engages the pawl 38, withdrawing it from the ratchet teeth 39 and the pawl'48 is turned clockwise about its pivot 49 thereby disengaging said pawl from the ratchet teeth 44. The disk 40, being thus unrestrained is restored to its normal position by the spring 43 and when the comb 1 1 restores the member 17 a projection 58 integral with said member strikes the pawl '16 turning it counterclockwise to restore it to its latched position, the latch 33 being always biased to the left by the spring 38.

Printing is effected by energization of a magnet 60 occurring when the cross head has reached the limit of its upward travel. When energized said magnet attracts its armature 61 fixed to a lever 62 pivoted at 63, at one end, the other end being formed into a hook shape which coacts with a stirrup 64 which rests in an indentation in an extended arm 65 integral with the lever 21. When the armature 60 is attracted the stirrup 64 is pulled downwardly causing the lever 21 to swing counterclockwise about its supporting pivot 22, thus movthe gear 19 and rack 18 become disengaged,

and in order to prevent said disk from turning when disengaged there is provided a brake 69 slidably fastened to the lever 21 by a pin and slot connection 7 0. This brake is normally held in its up position (Fig. 1) by means of the spring 71. Touching the upper side of the brake is a roller 72, ournalled in a bifurcated end of a lever 73, pivoted at 74 and biased in a clockwise direction by the spring 75. As the brake is wedge-shaped, there is an upward thrust against the roller 72 when the lever 21 is swung to the right. As the roller 72 is fixed against upward motion the brake 69 is forced downward against the type to lock the disk 24 from rotating. The sideward thrust of the roller 72 is compensated by the resilient spring 75.

Although a complete single printing section has been described it will be understood that as many such sections as desired may be placed side by side to print words or sentences in one printing operation.

WVhile there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
