TYPE-WRITING MACHINE.

To all whom it may concern Be-it lrnownthat I, ll'nimlur JoNATnAX Nmmmacitizen of the United States, residing at Madison.-in the county of Dane and State of :Wisconsin. have invented a new andusefnl Improvement in Type-Yv'riting Machines. of which the following is a speci-' Certain principles and features of my invention as. described herein are included within the generic invention which is decribed and claimed in my co-pendingap.

plication filed April 30, 190$). Serial No. 493,193. My general invention supplies the ope 'atcr of a, ty 'aewriting machine with autoinatic indicating means under the novel.

control of a ""39WI'liEP-I'DQChuIIlSHl part used in the eper on of tvpewriting. whereby without-ere cising'preliminary care he is ableto inform himself oi the position of his advancing sheet either with respect to the first line printed thereon or to some other point-on the sheet. it also supplies him with additional or with substitute indicating means under the novel control of such a typewritermechanisrn part. whereby such types'as desired oi' signaling devices and of machine-lock devices may be cmployedto indicate the arrival of the sheet into a predetermined line-position. The

present branch or division of the invention supplies the operator with such indicating means. The embodiment thereof shown in Figuresl, -l and 5 of the drawings cmplQYS an operativea-nember that is actuated from the platen under the control of the i line-space lever of the typewriter-mechanism, and the use of said line-space lever as a controlling agent 'for the indicating means constitutes on of the leading features of the present invention. Another ot the leadingfeatures thereof is the use of detent means forgivingthe operative member its initial or starting position. Other Eeatufes are as hereinafter described and claimed.

One of the leading objects of'iny present invention is to supply special types oi driving and controlling incans adapted. 'to 'be used in other combinations or separately tor similar sheet-position indicating purposes.

the stopping means effective, and second of main frame all of the typewriting machine in the usual manner, has ournaled in its? 10, whichis revolved by the usual line spacing lever 51. The usual paper table 8-'fo1:-.

as is also a type-bar 78, hearing theprintin the usual andwell-known manner of cer Taking now this already-if p provided structure asabasis, I place upon the platen arbor 13 outside the carriage taching the same fixedly to the platen arbor by means of the key This piece52 may talte a quite 'diiiercnt form from theg co-ne form shown in-Figpat. I place upon the platen arbor next adjacent said frictioncollar the toothed wheel 11, havingia' friction surface engaging with that ,upon'thepiece 59. whatever that maybe. Attached tothis modifiation is somewhat diagrammatically My invention as more particularly illusirated herein consists .ofa rotary part havpoint; controlling "means for the stopping,

tar; part,.con1prising'upward-cc n ting inice wheel 11 so as to revolve therewitha's a unit is the rotary part 6', bearing the projection 14. This part 6 is terraced as shown, and upon the step or shoulder thereof is seated an annular part 6", adjustable relative thereto and in frictional engagement with the said step or shoulder and also on the line 42. Both of these parts I construct of a light material like wood or aluminum.

Against the part 6 is placed the metal friction-ring 82, and the washer-like spring 57, the latter adjustable laterally upon the said arbor 13 by means of the screw-threads 56 and the pair of adjusting and lock-nuts 55. The platen arbor has the usual twirler 60 on the end thereof. I attach to the rear part of the carriage frame 12 the frame extension 22, and upon this by means of the pivotpin 25 is hung the lever 74, mounted to swing horizontally and having thereon the laterally projecting stop-lug 15. This lever is connected with the line-space lever 51 by means of the pins 64 and 66 and the horizontal connecting rod 65, the latter being supplied with the slot 67 at one end thereof. The lever 74 is also furnished with the spring 44, Fig. 2, the action of which-is such that tle lever'is' pressed always toward the left, away from the platen, and also is furnished with the horizontally projecting lip or stop-seat 62, shown more clearly in Fig. 2. I attach to the carriage frame 12 the hinged frame extension 31, by means of the pivotpin 9 atthe one end, and the thumb-screw 63 at the other. This hinged frame extension 31 bears the axle 21, upon which is journaled the toothed wheel 5 adapted to mesh with the toothed wheel 11 on the platen arbor. The wheel 5 should be in diameter some other multiple of the diameter of the wheel 11-twice the diameter, preferably. Projecting inwardly from that side of this toothed wheel 5 nearest the platen is the pin 20; and between this wheel and the frame 12, and pivoted upon the frame 12 by means of the shaft or axle 7, lies the lever or latch 1, provided with the turnedin stopend 61, and an irregularly-shaped working under face 19, the latter in certain positions of the latch jutting downwardly into the path of the pin 20 before named. The-carriage frame 12 has attached to it also the pointer or index-guide 34.

The action of the structure thus far described is as follows: Suppose the mechanism to stand in the position as shown in Fig. 2--the pin 20 by its action upon the lever or latch 1 has raised-the stop-end 61 from the stop-seat rest 62, upon lever 74 into a position above the lever 74, so that when the line-spacing lever 51 after its working stroke returns in the usual manner toward the left ready to begin another stroke, the lever 74 is also permitted to swing toward the left. The swinging action brings the stop 15 of said lever into the path of the projection 14 on the rotary part 6'. This parts upon the completion of a given sheet.

Suppose now that the sheet is twirled out of the machine in the usual manner by means of the twirler 60, and another sheet inserted and brought around into position for the printing of the first line: it will readily be seen that the turning movement of the platen will bring the projection 14 against the stop 15, which will detain the part 6 so that it can thereafter no longer revolve with the platen, but must remam stationary in a predetermined position. The first line upon the sheet will now be printed in the usual manner. Upon the completion of the line, the operator will press the lever 51 to the right in the usual manner for the purpose of advancing the paper sheet and shifting the carriage. This movement of lever 51, at the very beginning thereof and before the line-spacing mechanism has acted upon the platen, will result in movement of lever 74 away from part 6' and consequently 'in the withdrawal of the stop 15 from its stopping engagement with the projection 14,

as shown in Fig. 1. The art 6' will now be free to revolve with the p aten 10; and upon the further pressing of the lever 51 toward the right to space forward the platen for the printing of the next line, it will so revolve; and it will continue to revolvewith the platen until again detained by the action of the stop 15 upon the projection 14. The complete movement of the lever 74 to the right occasioned through the connections between the said lever and the line-space lever 51 carries the body of said lever out from under the laterally projecting lug or stop-end 61 of the latch 1, so that the latch is permitted to swing downward until said lug or stop-end 61 rests upon the stop-seat 62, shown more clearly in Fig. 2. When now the line-space lever 51 returns in its usual-manner toward the left after having made its working stroke, the lever 74 will follow its movement only so far as the stop 61 will permit-that is to say, not far enough for the stop 15 to act detainingly upon the projection 14. The stop 15 will remain in this position relatively to the path of projection 14 until the pin 20 again comes around and lifts latch 1 out of engagement with the lever 74, the slotted end 67 upon the connecting rod 65 permitting the spacelever to swing to the left independently of the lever 74, during the time while the lever 74 is detained in an intermediate position by stop 61. 1

It will now be seen that I have described a means whereby the rotary part 6' isb rought to a stop always at thesame rota-- two point, namely the stopping action of the stop 15 upon the projection 14, and a means whereby it is then released to revolve with the platen, namely the action of the 1 space-lever. 51' upon; stoppin'g means I have alsodescribeda 'yi'eldingfconnectimi.

with the platen'tha' will accommodate itself" to such a stop'pingfaction' upon the part 6, namely a frictional connection. Since the part 6 comes to'a "stop always at the same rotative point, it follows that it re: sumes its movements always from the same' initial or starting point. Supposenow that I supply the periphery of my part 6' with indices, preferably numerals, using marks that will indicate the position of the current line-point relatively to the first line on the sheet, and placing these indicating marks in each case so that when, respectively, in indicating position, each thereof likewise furnish with the numeral 2, the released part 6 having moved forward with sheet.

the platen between the printing ofthe two lines, and so on, as high as I wish to count, my released periphery sus'tainingf now always a constant relationto the advancing Such an indexed periphery might take the form of thejline indicator or'scale 6 in my drawings. Inmy Fig. 1 this "scale is shown as counting by the ordinary double spaced line-unit duringtwo full revolutions of the platen, or to'thiirty-thr'ee double lines, the platen-peripheryin the caseof most typewriting machine's today being divided into thirty-three singl'e line printing post tions, or in any event'into single-line print ing positions up to'somebdd number. If

1 such a platen be spaced forward by double lines instead of singlegthe same' peripheral point can come into theindicating position only upon alternate revolutions of [the platen. The indicating marksas "shown relating to the second revolution of-the platen will not therefore interfere with those relating to the first, but can be placed in a series side by side with them, or if desired between them, as in my indicating scale ,6". In my modification shown in- Fig. 3 is illustrated a more flexible method of counting lines beyond the lines printed during one revolution of the platen, the scale 6" and projection let being attached to a tbothed wheel revolving less often than the'platen. WVhen the lettered periphery is geared down as inFig. 3 to make but one revolution to'the two (say) of the platen, it can be made to count by single, double or triple'line-spac'ings at will.

My indices 6 are described as follows: hammer 26, the said h1g7 extending under- 13o single, double or triple line-spacings.

' Upbnthe periphery of the annular part 6" are placed indicating, marks, preferably numerals, arranged to count progressively downward, instead of upward, also by linepositions. This annular part 6 is adjustable to the. rotary part 6, as has been ex-. plained. 'Ishow it indexed to count bythe double-spaced line, the numerals-counting "during: the second revolution of. the platen falling between those counting during the first revolution. It could however be com- .bined in adjustable manner with the scale 6 shown in Fig. 3, ancllettered tocount by Its use is as follows: Supposel amprinting sixteen lines. upon my sheet, and wish to remove my sheet when the sixteenth line is printed; and suppose also that I am printing matter like tabular matter, that cannot wellbe divided, and wish to know line by line how far distant my sixteenth or last a line is, in order not tobegin upon matter that will not go into the space I have left; by bringing the numerallti of my indices 6 opposite the numeral 1 of my indices 6* and leaving it there, it will follow that during the time that my indices 6 are counting the line's upward on my sheet,beginning fromline 1, my indices 6* will be countingthem downward toward the last line, and .I will ;beenabled to tell at a glance, without making any mental computations, just how much printing space I have left upon the sheet. Or, I could set the scale 6 to tell the distance to the extreme bottom edge of. the sheet, instead of to the last line I intend to print, at my pleasure, by adding the depthin line-units of the bottommargin.

Any mechanism. havinga mode of opera-.

tion such as has been described,that is to say, having an operative member that is first broughtinto a constant starting: or in-- itial position, and thenat asuitable moment given a movement constant with that of the sheet, can be. made not only to operate indic'es, but to control and operate almostany form of signaling apparatus as well. In my drawings I show means for attractingthe operators attention thgough the striking of abell, and means for then rendering the machine inoperative, all operated or controlled by such an operative member.

My warning signal is given by the-following means; I attach tothe pivoted carriage frame extension 31 the further frame extension Upon this Iplace the outwardly-projecting pin 86 bearing the bell 27, shown clearly in Fig. l, butonly in dotted outline in Fig. 2. The. frame extension 76 carries also the inwardly-projecting pivot-pin 70, the same serving. as asupport ing axis for the trip-lever 69 having on it the outwardly projecting lug 71, and for the clapper-stem 72 hearing the bell-clapper or 20 journaled in the carriage frame 12. Upon neath the said clapper-stem 72 and acting will be raised and afterward released, fall-- liftingly upon it. The toothed wheel 5 carries near its periphery a series of threaded holes 68, in one of which the outwardly projectin pin 68 is seated adjustably to the. When now the toothed wheel reing against the bell and rin ing it. I prefer the bell signal given in. t is'manner, but other bell-signals may be employed, or signals other than bell-signals.

The means whereby the machine is rendered inoperative are described thus: The lever 1 already described is fixedly attached at one end to"the short shaft or arbor 7,

the inner end of this shaft and fixedly attached thereto is the crank-lever 4, bearing the pin 33. Extending from end to end of the carriage frame 12, and attached thereto operatively by means of the pivot-pins 24, is the bail-shaped stop-bar,29. This stopbar is so stationed and shaped that it can be rocked into a position in which the printing types 73 will strike upon it instead of upon the platen, or rocked into another position in which the action of the printing parts is not afiected; and it is connectcd'with the crank-lever 4 before named by means of the ins 23 and 33 and the connecting rod 40.

hen it is time for the machine tobe rendered inoperative, the pin 20, inwardly projecting from the wheel 5, presses against the downwardly projecting portion 19' of the lever 1, thus raising the lever 1, and through the connecting parts raising the, stop-bar or bail 29 into a position blocking the printing action of the. type 73. This position of the parts is clearly shown in Fi 2. The working face 19 of the lever 1 referred to will be so shaped that onespacing stroke will raise the stop-bar 29 into the blocking position, and another spacing stroke will be required to lower it. The parts are to be so weighted and balanced that the stop-bar 29 will fall of itself into an idle position when released. v

I will now describe more particularly the use of my invention. 7

Suppose I wish to "rint a' small page, say sixteen lines in lengt I first turn my indexed periphery 6 until the numeral 16 thereon lies within the index-loop, or at the pointer. I then loosen the thumb-screw 63 and rock the frame extension 31 downward on its pivot 9 until the toothed wheels 5 and 11 are disengaged. I now turn the wheel 5 in its normal direction on its axis .until the bell-signal is given. I have now only to throw the two toothed wheels into mesh spacing lever 51is placed adjacent to the figure.

again by raising the frame extension 31 into place and fastening it. My signal bell will now always ring when the platen is spaced forward for the rinting of the sixteenth line, and my mac ine Wlll always be ren-" dered inoperative if the platen is then spaced forward for the printing of an additional line. If for any reason I'wish to add further matter to my page, I can always do so by turning my rotary artfi' forward or backward relatively'to t e platen, the light frictional connection readily permitting of the movement. Such a manipulation would not in the least affect the operation of my mechanism relatively to the printing of the next sheet. And in addition to my hell signal and to my means for rendering the machine inoperative if the bell signal be disregarded, I have the entire series of indices 6", to indicate as already described the number of lines I can still print on my sheet, beginning with my first and ending with my last.

. In certain typewriting machines the lineleft end of the carriage; and I wish to show a means whereby the mechanism may be more directly connected therewith, some of the parts being omittedx In my Fig. 3 is shown such a modification. The toothed 1wheel'11 here has a frictional connection with the platen as before, but the indices 6" are attached to revolve with the toothed wheel 5. The toothed wheels in this arrangement may be of any diameter relatively to one another. The wheel 5 turns on the pin 21,.here stationed on the carriage frame 12 in a fixedrelation to the platen arbor. The spacing lever 51 has attached. to it the projecting detent 15, and normally stands in a position in which this detent lies in the path of the pin 14. During the twirling out of the completed sheet and the ositioning of the new one this pin 14 wil be stopped by the detent 15, and the indices stand with the numeral 1 or the peripheral position therefor inthe indicating position above the pointer 34, as before; and during the writing of the first line this will be the position of the parts. The line-space lever 51' will now be pressed to the right, instantly removing the detent 15 from its detaining engagement upon the pin 11. A further movement to the right of this lever-namely tothe position occupied by it in Fig. 3

will space the platen forward for the printing of the second line, in the usual way.

This movement of the platen will affect the now released toothed wheel 5, and the numeral 2 of the said indices will be brought 1'25 into'the indicating position, as shown in the And so on, to the end of the sheet. Signaling and locking mechanisms may be added, corresponding to those shown in Fig. 1', as may be desired, and the scale 6 as well.
