To all whom t may concern: I

Be it known that 1, Jason C. LOTTERHAND, a citizen of the United States, and resident of New York, .in the county and State of New York, have invented certain new and useful Improvements in Printing Mechaof which the following is aspecification.

' One of the objects ofthe present invention is to provide an improved form of means for printing the signals in an adding machine, that is eitected by the operation of simply depressing one of the signal keys, and the printing is accomplished at once be fore any movement whatever is given to the main operating handle .or member of the machine.

A further object of the invention is to provide in such a device, in connection with the total and sub-total keys, means whereby the mere depression of either of these keys will to be printed at once, and before any movement of the operating member. l

A further object 01' the invention is to provide in an adding machine having the usual set of members known as rack and type to position the type plates for printing, improved means for accurately positioning or locking the type plates atter they have been positioned to print, to effect the proper alinement of the type at the printing position.

Another object of the invention is to provide in an adding machine that operates both an adding and listing device, an imroved means for permitting the operation of the adding mechanism, while the printing mechanism is prevented iromprinting.

In the accompanying of my invention, Figure l is a plan view of a portion of an adding machine with my invention applied thereto; Fig. 2 is a side elevation showing the signal keys and connected parts; Fig. 3 is a view of parts shown in Fig. 2, in other positions; Fig. i is an elevation showing the printing devices; Fig. 5 is a fragmentary view showing the printing devices inother positions, and Figs. 6 and 7 show the means for locking the rack and type plates in printing positions. A I

It is customary in adding machines to prodrawings, repre-' Specification of Reissued Letters Patent. Rgissugd A 0. 22 1916 Application for reissue filed April 16, 1915.

vide in addition to the adding mechanism, means for printing on a suitable record, the items as set up in the machine, also the total, and sometimes the sub-total. further customary to have a special character or signal printed on the record adjacent the total, or the sub-total, or other-number that may be printed, to indicate its special character. One form of character will be printed opposite the total, another form opposite a subtotal, and sometimes other charactors for numbers that are printed but not included in the sum and which do not afi'ect the adding mechanism. Also sometimes an item is included in a sum sired to print this item, when a certain char-. acter can be printed adjacent the blank space but it is not deon the record. A y

In the form of machines atpresent in use, the printing of special characters, While it is usually automatic in its operation, is efl'ected simultaneously with the printing ofthe several members to which they relate. Ob-

viously, where a non-print sign is used there is no, printing effected. It has been found desirable to rate and distinct from the numeral printing mechanism of the machine, and in the present invention such an operation takes place. Furthermore, the printing of these special signs is done at the time the special keys for such characters are depressed, and not subsequently upon the movement of the handle or main operating member-of the machine. To be specific, when either the total or sub-total keys is depressed, or the nonadd key, or the nonprint key, immediately the corresponding character is caused to print on the record, which operation is'completed before any movement whatever of the main operating handle or member of the mechanism..

do this printing entirely sepa It is The machine is shown as comprising a hammer 9 that will shiftable to bring strike the positioned type of its corresponding rack and type plate to efiect the impression on the platen. By this means a row of figures willbe printed in a horizontal line on a record sheet on the platen, and-it is desirable to print the special character or signal adjacent this number preferably at one side, such as the right hand side, as is done in the construction set forth herein. The hammers 9 are shown as all mounted to swing on a cross shaft 10, seeFigs. 4 and 5, suitably supported at each end, and each ammer is provided with an energizer lever 11 having contacts 12 and 13 for engagement with the rear edge of the corresponding hammer, these levers swinging on a stationary shaft 14, and bei g retracted by a spring 15 at the lower end of the lever to swing the lever and cause the hammer to strike, when the hammer has been retracted.

Coiiperating with each hammer is a trigger 16 mounted on a suitable shaft 17 to swing thereon to cause a hook 18 on each trigger to engage a tip 19 connected with each hammer 9. The shaft 17 for the triggers, is mounted on a pair of swinging levers fast on an operating shaft 21, by which the levers are swun to shift the position of the shaft 17 and t ereby bodily move the triggers back and forth. Aspring 22 connects each trigger with a suitable fixed place, to swing the triggers and bring the hook to engage the tip 19. But when the levers 20 move the shaft 17 rearward carrying the triggers back, an arm 23 on each tngger engages a stop bar 24 that will swing the triggers against the force of their springs and trip the hook from the tip. When the triggers moved the hammers away from the type, they swung forward and placed their energizer levers under tension, and when the triggers are thus tripped, the hammers will be. released to strike the type.

with an xtension 26 carrying a stop 27 normally engaging thetop edge of the trigger 16 to hold the trigger down withits hook below the tip of the coiiperating hammer so that when the rack and type plate is in tlfis position, the rearward movement of t e trigger by the swinging of the lever will not affect the hammer. But as soon as the rack and type plate, rises the hammer will rise and cause the hook to engage the tip.

The rack and type plate is provided with a rack 30 on its front portion to engage numeral wheels 31. At the foot of the rack and type plate is a stop 32 arranged to en gage stop bars 33, asindicated in Fig. 7-, the stop bars being each connected with key stems 34 by means of a bent lever 35. At the rear of the rack and type plate at its foot is another lug 36 arranged to engage a universal bar 37 mounted on the side arms. When the shaft 21 is swung by means of Each rack and type plate 7 is provided BEST AVAILABLE coPx an arm 38 connected with a side bar-39, the universal bar will permit the rash and type plates to he elevated by springs 4&0. Eafch' rack and type plate has suitable guides l-1 and -12 sliding on posts 43, in'each of-Which is placed the'spring 4C0, that will elevate the rack and type plate when free to move upward. When the universal bar travels upward each rack and type plate will be thus drawn upward until its foot 32 engages a stop bar that has been set by a key, when the rack and type plate is arrested with a type in the printing position opposite the hammer that corresponds with the key depressed. The side bar 39 is shown connected with a crank 25 fast on a crank shaft 87 operated by a handle 75. This shaft 87 extends across the machine and carries on the opposite side a crank 88, see-Fig. 2, that operates a side bar 44 similar to the side bar 39. A. crank 45 connects shaft 21 with the side bar a l.

In order toaccurately position or look the type carrier portion of the rack and type plate when it rises to engage a suitable stop bar, as indicated in Fig. 7 the extension 26 is provided with a set of recesses 46, as indicated in Fig. 6, and a lock bar 47 is provided that will be advanced to engage one of these recesses just before the printing operation takes place. These recesses are spaced apart corresponding to the exact relative position of the-type so that when this bar. enters a recess the positioned type will be precisionized and locked. The bar 47 is mounted at its ends on levers i8 and 49, that are suitably pivoted at engage the universal bar 37 at the final portion of its upward movement, whereby the swinging of these levers will move the bar 47 into one of-the recesses 46 just at the stage when the printing operation will take place. A spring 58 serves to return the arms and bar as soon as the universal bar begins its return movement, and they engage asuitable stop pin 51 to hold the bar out of the path of the rack bar extension.

Means are also provided for preventing operation of the printing hammers, when the raclrand type plates are elevated to actuate the adding mechanism, which is known as the nonprint operation. In Fig. 4c is Shown a bar 52 carried by a pair of suitably pivoted levers 53, that lies on top of the triggers 16. This bar-is normally free so that the triggers will not be interfered with in their upward movement. But an arm 54 connected with one of these triggers, extends to the rear and is provided with an ear 55 arranged to be engaged by a stop arm 56 mounted on a rock shaft 57 suitably supported at the rear of the machine and extending beyond the left side plate 3. This shaft is rocked by means hereinafter set forth. In the position shown in Fig. 5 the stop 56 will hold bar 52 engaging the trig 50. These levers .sitioned whereby the BEST AvmLAe EcoP.

Th iink (52 serves to swing the crank 61 to return bar on the forward movement of the side bar 14; by the operating handle in the normal operation of the machine. iktotal key 65 is shown that is vertically slid-able and carries a lug 66 arranged to engage the bar 66* when the key is depressed. The bar has an inclined lug or cam 59 arranged to engage the lug to ,hold the bar '66 in normal forward position with the spring 6 L under tension. A-sub-total key 6? a. pin 68 arranged to engage the bar and depress it, whereby the bar will have the lug 59 disengage the pin 66, and thus permit the spring @4- to draw the rearward; the latter movement being limited by a. stop 69 on the A third key 70 which may be the non-add key, is vertically slid. ole to have its stop 71 engage the bar to swing it and release-it from the stop 66; and the rearward movement is limited by a suitable stop 72. Thus the stops of the keys 6'? and are relatively polatter will permit a greater rearward movement of the bar 60; it being understood that the depression of the key 65 will not permit any rearward movement of the bar. A fourth key 73 is shown that may be the non-print key, hava stop'is arranged to strike the bar and swing it down to disengage'the stop 65. But no limit abutment is provided for the stop 74:, whereby the bar 60 can be moved rearward its full distance. It will be under stood'that these four keys will each swing the bar downward, and that three of them will permit rearward movement of the bar for different distances, respectively, while the fourth key will not permit any rearward movement. l l hen the bar 60 has been shifted rearwardly, the next operation of the operating member, side bar 4 and crank d5 will cause the link 62 to swing the bar 60 forward again, causing the cam stop 59 to rengagethe stop 66 to lock the bar in its normal forward position. It will be understood that the operationof any one of these three keys will shift the bar 60 rearward to rock the shaft 57 a different distance. When the non-print key is depressed the shaft will be rocked its maxnmun distance, and this will be effective to move the stop arm rearward a maximum distance to lock the arm to hold all the tri' ggers 16 out of pivoted at its rear to a crank 61 fast on provided hat "ingmoving downward will be position for engagement with the hammers.

At the right side of the described rack and type plates is a printing plate or carrier 76 carrying four type, a, "0, c, and (Z, see Fig. L, that can be brought opposite a printing position on the platen. This carrier 76 is pivotedto an arm 77 fast on the shaft 57, and these 'parts are so arranged that in the four positions of this shaft 57 produced by the depression of one of the said four keys, one of these type is brought to the printing position.

.W hen the total key is depressed, the bar 60' is not shifted, and the s 1ft remains stationary, the type d will be u position, which is the total character print ing type. A hammer is suitably pivoted to strike these type i positioned, and is provided with. an ener; :er 7 9 controlled by a spring 80 similar t" those described. A special trigger 81 is ovided to cock the hammer 78, being co looted similar to the triggers described, anc mounted on thesame shaft 17 whereby the hammer 1s cocked when other ham ners are swung back. When the hammer '38 has been cooked, it isheld bya latch 82 that engages an car 83 on the the hammer to hold it in its cocked position, the latch being swung forward by a spring 84. In the normal operation of the machine by which the hammers are cocked and then released, this hammer 78 will be cocked to: engage the latch 82, that will hold it in the cooked position and it will not be tripped at this time. To trip this latch, an arm 85 is provided fast on across shaft 86 that is secured to the bar 60 at its pivotal connection with the crank 61.

When one of these four keys is depressed, for instance the total key, the bar 60 cannot move rearward, and at the final part of the downward swing of the bar 60, the shaft 86 will swing sufficiently to cause the arm 85 to trip the latch and permit the cocked hammer 78 to strike the type in the carrier 76; the type for tioned. But when any of the other keys is depressed, as the key 70, its pin 71 will strike the bar 60 and swing it downward, but the initial movement will not be suflicient to' trip the cooked hammer. The bar in disengaged from the pin 66 and the bar will be instantly drawn rearward by the tensioned spring 64. This rearward movement of the bar 60 will rock the shaft 57 and shift the carrier 7 6 to bring the non-add character to printing position. It will be understood that this rearward movement of the bar is efiected instan' taneo-usly before the key 70 has been depressed its full distance, downward movement of the key the bar will be swung suiiiciently to rock the shaft 86 and swing the arm 85', tripping the latch to release the cocked hammer, and the non-add character will print.

rear of the total being normally posi-' and at the final The same applies to jposite the printing the other two keys 67 and 73, in which case the carrier will be first shifted to bring the proper character to printing position, and thereupon the cocked hammer will be tripped. It will be understood that this operation of printing the character is performed at once u on the dcpression of any of these keys, an is absolutely independent of the movement of the operating handle and connected parts of the machine. But the operating handle rves to restofie 'the side bar 60 to the former position, and fun ther to re-cock the hammer 7 to be ready lfpr the next operation of any of these four eys,
