TOTAL-PRINTING- MECHANISM non LISTING-MACHINES.

' Application filed September 17, 1503. Serial No.173,55 i.

. :Be it known that we, Donn E. FELT and CHARLEs P. .WETMORE, citizens ofthe United States, 'residing-inChicag'o, in the county of Cook-and State of Illinois, have invented a new and useful Improvement in Total- Printing Mechanism of Listin Machines, of

whichlthe following is a spec' cation. This invention relates to the total printing 3o mechanism, of that class of recording arithmetical machines commonly known as listing or tabulating machines. structed, these machines have either been I provided witha separate operating lever for if causing the rinting of the total, or they have been provi ed with a setting key whereby themechanism' isset for the printing of the total, so that when the mainoperating lever isnext operated,, the total will be recorded. In our present invention, We aim both to dispense with the total printing lever and with the setting key of previous machines,

I and we accomplish this .result through the medium of the main operating lever which wenow ada t both to set or prepare the I mechanism or ,printing the total and for actuating the mechanism to the printing. In order that the operating leverinay perforrnboth these functions, in addition to its 39 other functions, we give it a strokedifl'erent fror the stroke which-it receives when oper- 'ating the machine in listing and adding. Thus in the case of machines whose operating levers.

.are moved toward the front of the machine inthe ordinary listing and adding operations,

We give the lever a stroke backward from its position of rest for the total printing, of

course, but, of course, we do not wish to be limited in this regard. During this stroke by which the total is printed and which is to be distinguished from the return stroke of the lever in its normal operation while listing the numbers, the lever in the first part of the stroke sets or prepares the mechanism for printing the total, and in the last part of the stroke, it causes the printing.

In addition to this, the invention also embraces other features'of invention which together with the main improvement are fully ,so set forth in the description which we give below. 4 In the accompanying drawingforming a part of this specification, Figures 1, 2 and 3 i are partial side elevations of portions of a listing machine embodying'our invention,

' Specification of Letters Patent.

As heretofore con-l Patented June 2,1908.

the operating lever beingshown only in.

broken lines'in Figs. 2 and 3 so as not to obscure the arts back of it. Fig. 4 is a plan of the mec anism shown in the other figures.

Fig. 5 is a section on the line-5-5 of Fig. 1,

and Fig. 6 is a section on the line 6-.6 of Fig. 1. l Fig. 7. is a detail elevation of the printing segmentlfor printing the-lettersS and T 0pposite t e total. Fig. 8 is a side elevation of a listing machinev in which our improvements have been embodied. .Fig. 9 is a longitudinal section of the same, and Fig. 10 is a section on'the line 10-10-0f Fig. 8.

The present invention is shown in 8, 9 and 10, as applied to a tabulatingmachine known as the com togra-ph, the construction OfWlliGh is fu ydisclosd in an cember, 1904, as- Serial No. 238,316." For the purposes of this application, it isonly necessary to refer to a portion of the devices application filed by us on'the 27th of De- I illustrated in these figures,-and we therefore notethat 200 represents the denominational kys, 310 one of the lon itudinal movable bar's having inclines 340 t rough which it is actuated by the keys, the inclines being adapted-to impart varying movements to the bar so that the bars are thereby enabled to determine the action of the adding and. printing mechanism. The bars 310 each actuate a corresponding variable acting link 390',

each attached to a column actuator 400 by which the corres onding numeral wheel 410 is" turned in ad ing and the corresponding type segment 39 is positioned through link 260 for printing. The link 390 engages the notched graduated arm 4'50 yieldingly mounted on and rocking with shaft 480 which we call the main actuator. The key determines which of the notches shall be engaged by the link, and when the main actuator is rocked forward by the lever 11 through any suitable connectin ,mechanism, one const uction of which is ully disclosed in our said application, No. 238,316, and of which the springs 206 Fig. 10, form apart, the link depresses the column actuator in aCCOI'dBJIGBWIth the digital value of the key, and actuates the numeral wheel and typesegment accordingly. The hammers of. the printlng mechanism are shown at 1.70 and swing on shaft 171. They are actuated by springs 172 and are normally held by triggers 177 released by frames 178. The construction of the releasing frames.

and their mode of operation are set forth in .2 7th 1900'. i

d hen the main lever moved backward as hereimifter explained, itopemtes the lever so and causes the sliding of the cum bars 310 to a non-acting position, through the medium of swinging lever 73 mounted on on actuating rock slmft Tl, link 83 operated by the 11min cum aud'having a shoulder engaging the lower end oi lever 73, the lever 75 on rocking shnft- 74-, and plate '76 carried by lever and engaging the projectin shoulders 95 on the cum bsrs. \Vien "the ever 36 is thus opera-ted, it -also carries with it a bar 100. This bar- 'lms 2: slot 101 in WlllC-ll is a pin carried by the lever, and at its forward end the bar is attached to crank i023 on e rock shaft 10% extendin over the series or I numeral wheels. Shaft 10%. is angular, and when rocked, it deiresses the series of lockin stop levers it): locking the wheels.

The forward movement of the r erating lever may alsoibe made a means of lif mg the tvperibhon from. its position of rest to its acting; position, and we have shown means accomplishing this result and which are its lows: On the shaft 12 is a, czun 20 having we I points 50 21 .1451, both cl' wnich. come in eonrect with e pin 21 on a lever '-'.lWJiCl9.-t 23 and connect by av link to the frame 25 pivoted 4 t adding mechai 36, and. localso be- .veen the specs operating the ribbon 2?.

For printing the total, the operating"lever moved "from the position of Fig. 1, to that of Fig. As already ex )h'tined, this opera-tes tillO roe-k shaft 18, in the same manner as does the forward movement of the lever. it also causes the setting of the mechanism preparatory to printing; the total, and this it does through the medium of a com 320 on i-z-iurl t This corn, when the lever is mowd. backward for. printing the total, presses against the latch. 32 which is pivoted on the elbow le er 33 and is held by at stop 4-0 from swinging in one rhrection. A spring 41 maintains contact by the hitch with the stop.

The lever 33- is pivoted at 34 and connected by slink {$5 with :1 lever-T56 pivoted at 37. This loner has a horizontally extending arm and through this arm the positioning o! the type segments for miswcrprinlmg is ncrig". to its printing position shown at ms irerne carries guides for the ribbon or ails again to the position of Fig-.1. ,T his ribr t e main lever, and lever 36 causes the setance by arm 38 of its said function. The

The lever'36 corres onds closely so far as it aids in the total printing, to the lever 70, of

the atent to Dorr E. Felt, No. 749,177,

' date January 12, 1904, though the patented lever is operated directly by the handof the o erator'mstead of receiving its power from Q of the mechanism for the printing of the answerand the printing thereof, in thesame way asl the-lever 70 of the patent accomplishes these results.

We have shown two ribbons in the application, the ribbon 27 being the blue or pur- 'ple commonly used in printing the numbers added and the'ribbon 42 for the printing of the totals: The latter ribbon is preferably red 'orsorne other color differing from that of ribbon 27., l The backward movement of the operating. lever is intended to lift ribbon 42 into acting position and it does this by the following means: The point 51 of the cam 20'- jac'tuates the lever 22 and through it the ribbon frame, carrying it from the position of Fig. 1 to that of Fig. 8 and bringing ribbon 42 opposite the printing line, so that when the answer is printed, it will be done in red or some othercolor.difierent from the ink used in listing.

,. It is frequently desirable to print what may be called sub totals, that is, totals of a portion only ofv the items listed, as, for'in- 'stance, those in a particular column Instead of the rand total, and it is desirable to dihtihguisli such sub totals from the grand totals.- Forthis purpose, we add to the series 'oftype segments a special one 52 having upon it the lett ers'l and'S, T being used with l the grand totals, and S with the sub totals.

The type are arranged upon the segment as indicated at Fig. 7, the S being the upper letter. The segment is mounted uponthe same shaft 26 with the numeral segments and yby the user'.

' the ribbqrr frame, and is operated in the manner now to bedescribed. I At 53is a hand lever for operating s'eg merit 52. It projects aboveltheto .of the machine so that it may be operatei atwill It is pivoted at 54 and on the f same shaft 54 is a vertical standing lever 55.

fright an les so that the bent portion stands 3 i the pi tends to keep the latch inits normal position.

, ;Adjacent to the lever 55 is a second vertical an elbow lever rocking u on shaft 61 and e l j adapted to be engaged by t e pin 31 on the.

I arm 30 of shaft 12, Then per end of lever 55'isconnected tolever 59 y link 62 slotted 5st its unction with lever 59 and a spring 63 On the side frame of the machine is ivoted a'jlatch 56 having its forward end 57 ent at ane of the hand lever. A spring 58 lever 59, the lower end of which is pivoted to also connects the up er portions of the two normal position, the pin lies atv the inner end.

of the slot, and remains there ino erative during the listing operations, but w en the operating lever is moved for total printing,

e pin 31 rocks the elbow lever 60 to the po-' sition shown at Fig. 3 and thereby pulls.

down the forward end of the type segment 52, raising the other end sufiiciently to osi- .tion the letter Tat the printing line, an this is always the operation when the hand lever 53is not shifted. If a sub total is desired, the lever 53 is shifted by hand to the position of Fig. 3 and this causes the shiftin of pin ,65 from theinner to the forward end of slot 64 so that a less movement of segment 52 isprbduced than would be the case if the in remained at the rear end of the slot. VV th the parts; in the positions just mentioned, the movement given to segment 52 positions the letter S at the printing line.

The main lever may be arrested at its position of rest by, any suitable mechanism, such, forinstance as the spring plunger 110 entering the notch 111 in collar 112 on the shaft of the lever. See Fig. 10.
