TYPE-WRITING MACHINE.

Specieation of Letters Patent.

Patented Feb. 18, 1913.

To all whom it may concern.'

Be it known that I, lViLLiAii J. Nanne, a g citizen of the United States, residing at- Madison, in tlie county of Dane, State of Wisconsin, have invented a certain new and useful Improvement in Type-l riting Machines, of which the followin is .a specification, reference being had t erein to the accompanying drawings.

Certain principles and features ot my invention as described herein are included within the generic invention which is described and claimed in my co-pendin a plication tiled April 20, 1908, Seria o. 428,212.

Thev objects of my Ainvention are broadly to indicate to the operator by automatic means the position of his current line upon the sheet, either. relatively to one of th e edges thereof, or to certain other line positio'ns.

The objects of that form of my invention more specifically illustrated in the drawings accompanying this speciiication are, first, to indicate to the operator the distance to the bottom edge of his sheet, or the. bottom line of his page, from his current printpoint, and this line by line and automatically beginning as far upthe sheet as may be ound convenient; second, to give him a preliminary eye signal upon the appreach of the end of the sheet; third, to

y supply him signal, upon the completion of his predeter- 85 mined last or pext-te-the-last line; fourth,

to then block the machine and render it inoperative; fifth, to enable him then to release the machine for further printing; and sixth, to supply certain means adapted t o 40 be applied to other paper-movement-indieating uses 'of the same general character. As machinesre at present constructed in practice, the operator has no convenient means of knowing how near he is to the end,

L6 of his sheet until too late to leave a suitable bottom margin. This is more especially` true of front-strikefaiid top-strike machines, bei'nuse inthem the bottom edge of the sheet y 1 entirely out of siglit`behnd the 6o platen whilemportion of the sheet still remains un supply the operator with a system ofadequate signals-whereby liiity knowfwhentoJstop his page; aidliu additionA I automatically 'measure for him with a signal, preferably an ear 56 the'uuused space left upon the paper-sheet i irrespective of its length, beginning long before the time to remm'e it, and continuing to the very end so that without preliminar care lie can loo ahead at any time and tell whether he has room on his sheet for a group of matter like a foot-note, or a'table, or a chapter-heading, that cannot conveniently be divided, and tlius stop his page in advance of the predetermined The latter function has never ore. been performed, but is novel to my invention.

I attain my several objects by means of the' mechanism illustrated in the accompanying drawings, in which- Figure 1 is an end view of the preferable application of my principle to such mechanisms of the character described as more specifically' embody a sheet-control; Fig. 2 is a front view partly in vertical sect-ion of a portion of the same; Fig. 3 is a detail end view partly broken away illustrating a typical modification; Fig. 3 is a sectional detail view of the said modification; Fig. 4 is a detail end view of another typical modification; Fig. 5 is a top or plan view of the parts carried by the frame extension 19 shown in Fig. 1; Fig. 6 is a cross-section' of a portion of Fig. 1, on the line A A; Fig. 7 is a front view of a portion of Fig. 4, on the line B; and Fig. 8 is a plan view of one end of the carriage and the arts shown in Fig. 1 in connection therewitxli.

SimilarV symbols of reference refer to similar part-s throughout the several drawings. Y

My invention as more particularly described herein consists of a rotary art oonneeted more or less directly with tI e platen by means embracing a mutilatedlgear; indieating means controlled or operated by the `rotary part, comprising a series of indices, an eye si al, an ear signal, and means rendering t e machine inoperative, whether one or all; and means controlling the ac- `tion of the mutilated gear. whereby it is rotated until disengaged, then remains disengaged'from the p aten until the sheet becomes suitably positioned, and then, from o constant starting or position, is made to e therewith.

The preferable application of the prin Aeiple underlying the invention is that shown in my l: 1, 2, 5 and 6, in which the platen car'riagee 12, carried upon the main yigge-length. A

frame 41 of the typewriting machine in the 110 usual manner, has journaled in its ends the platen arbor 13 as shown, bearing the platen 10, which may be imagined as connected` with the usual line spacing mechanism, not y shown herein. The usual paper table 8 for ing attached in the usual way to the carf riage frame 12. Taking this structure as a toothed wheel 11, shown more clearly in Figs. 2 and 6, connecting it to revolve as a ing relation in one rotary direction with the sleeve 21 and the paper-feeler 2S as shown. The paper-feeler is supplied with a knucklejoint -as shown, consisting of the pivotlpin 23, the lug` 65 and the stop-pin 24. The axle also bears a lug, lettered 17, limiting the movements in one direction of the i sleeve 21 and its attached parts through the stoppin 62 on the weight 63before mentioned. The axle 2O is so stationed, and the basis, I place upon the platen arbor the unit with the platen, as for instance, by attaching it to the head of the platen by means of the pins or screws 44. Upon the platen arbor I place also a composite rotary part, l

consisting of the adjustable disk 67 which carries the pin 68, and the toothed rim 5 and drum 6, the rim and drum being locked together by pins 43. The disk 67 bears also near its periphery the lock-screw 1S, the.

head of which overlaps upon the piece 5, so that when tightened it will lock the disk 67 and the toothed rim 5 together. The toothed rim 5 has one vportion of its periphery broken away, so that no teeth are stationed thereon, this portion being indicated in the several drawings by the lettering 75. The bushing-strut 42 helps to hold l these several parts in position. The drum'6 carries also Within its structure the weight 25, stationed in such a way that the center of gravity of the entire rotary part is decidedly eccentric to its axis. It is to be understood that the rotary parts 6, 42 and 67 are not-.attached to the platen arbor, but turn loosely thereon. Leaving now t-he parts shown as stationed upon the platen arbor, in the case of the toothed wheel 11 fixedly,

. and in the case of the drum 6 and its atytached parts loosely, I show attached tothe carriage frame 12 andprojecting inwardly therefrom, the axle 73, bearing the pinion 74. This pinion is in appearance a double pinion, connected by a hub; and it is shown in Fig. 2 as straddling the drum 6, adapted to engage with both the toothed wheel 11 and the toothed rim 5, and, except when the untoothedl portion 75 of the periphery of rim5 comes oaposite thereto, combinin'g the toothed rlm and its attached parts to turn with the platen. The carringe frame 12 carries also the frame extension `19 attached thereto, bearing the inwardly projecting axle 20,-upon which rocks the hub or sleeve 21, shown clearly in Fig. 5. This sleeve carries tixedly attached thereto at one end thereof the Weight 66 and at the other end the paper-feeler 28. On the same axle therewithls independently mounted the loosely-turning stop 15, provided with the lug 63. which bears normally against the stop-pin 62 projecting from the' parts thereon so arranged that the stop 15 normally projects into the path taken by the pin 14 on the tootlie rim 5, while the paperfeeler 28 is suspended above a slot or opening 4 in the paper table 8 in,suvch a manner that it can swing freely therethrough if the slot be not closed by a paper sheet.

The action of the structure thus far described is as follows: Referring to Fig. 1- it will be seen that if a forward movement be given the platen 10, the only parts for the moment affected thereby will be the toothed wheel 11, attached to revolve with the platen, and the toothed pinion 74, meshing therewith. The toothed rim 5 and its attached parts will not be affected, because the periphery of the toothed rim is broken vaway opposite the pinion, and, although the rim 5, because of the action of the weight 25 carried by the drum 6, has a tendency to revolve forward into mesh with the said pinion 74, it is prevented from doing so by the stopping act1on of the stop 15 upon the pin 14. The stop 15-normally ies in the path of the pin 14; but when breasted by the said pin, normally it merely brushes backward out of the Way, the paper-feeler 28 at the other end of the hub 21 passing through the slot 4 and permitting the movement. When, however, the paper sheet 45 lies upon the paper table over the slot, the paper-feeler 28 cannot so swing and the piece 15 cannot brush backward out of the' Way of the pin 14. But the moment the paper sheet passes from under the end of the paper-feeler 2S the said paper-feeler will be left free to describe its customary are through the slot 4, the stop 15 will cease to have a stopping action upon the pin 14 but will brush downward out of the Way, and the weight 25 will bring the rim 5 at once into mesh with the pinion 74. The composite rotary part attached to the rim 5 will thereupon enter upon a movement with the platen, and will continue moving therewith. I do not limit myself in all cases to the means shown to detain the rim 5 out. of engagement with the pinion 74, nor to the means shown to send the rim 5 forward into engagement therewith.

I have described a means whereby the rotary drum 6 is brought to a stop always at the same rotative oint, gi ven the presence of the working s eet. Since the part 6 comes to a stop always at the same rotative point, it follows that it resumes its movements always from the same initial or starting point. It is always clear that it begins its working movements at a moment when the sheets bottom edge has arrived at a fixed distance from the printing point. I supply the periphery of the part 6 with indices, and supply a pointer or indexguide 34, which may conveniently be attached as shown to the paper guard 31. .I place a zero mark opposite my pointer like that marked 89 to indicate my stopping point, which is also the starting point, and begin a series of indices at that point on the peri hery of part 6 lying opposite the pointer at t e moment the sheet and part 6 have been advanced in unison to the n'ext line point, the first index indicating say the distance at that moment from the printing point to the bottom edge of the sheet, and the next another distance. and so line byline. I thus have an indicating means that will always within its ranve give automatically the distance from eac currentprinting point to the bottom edge of the sheet. Suppose for instance that my periphery comes toits first stop after resuming its movement at a moment when the bottom edge of the sheet is distant seventeen single lines from the printing-point-I mark my periphery 17 to indicate that distance. I advance my sheet say a single line, and mark my-periphery 16 to indicate the new distance. Andso on, down to 1. Such is the markin shown in the drawings. Or, if I choose, can space by double lines or triple lines, instead of single. Or I can use still other units of measurement. And, instead of indicating the distances to the bottom edge of the sheet, I can indicate the distances to (say) the bottom line position just as well, as will be readily understood. I

prefer to use indices that involve no calculation nor memorizing on the part of the operator, but itis not essential that the indices be of such character.

Any device having a mode of operation such as ha's been described, that is to say, bringingan operative member into a-constant initial or starting` position and then giving it a movement constant with that of the sheet at a constant point in the sheets progress,-'can be made not only to operate indices, but to control and operate almost any form of signaling ings I show means for attracting the operator-"s attention first through Ahis eye and then through his ear, and after that, a means for rendering the machine inoperative, all operated or controlled by the composite rotary member 5--6-67.

My visual or eve signal is described thus: I propose to divide the periphery of the part 6 into two sections, the one, the working section, consistin of the portion bearing the indicating mar s as described, and the other apparatus. Inrny draw Y being left blank. The working section I propose to color in striking contrast to the other section-say a white background with black indicesmarkin thereon for the one, and a solid black for t ie other. The indexguide or pointer 34 I propose to extend out. over the periphery as shown, so that during the 'time the periphery is detained with the.

point 89 opposite the pointer, none of the white or indices-bearing portion of the periphery will be visible to the operator, but when the periphery enters upon its working movements with the platen, the white or indices-bearing portion will be brought into view and the black portion will disappear. The striking change from black to white will be noticed by the operator, who will then understand that 1t is time, or near time,

for him to remove his sheet. Such a signaling or indicatin means could be used alone, without the ad ition of any indices whatever, and without the addition of any other signaling means. The index-guide 34 need not be shaped so as to extend out over the periphery as shown--the working sect-ion of \the periphery would lie almost entirely out of the view of the operator, without it. Other color arrangements than those named can be used.

My audible or ear signal is given by the following means: I station upon the carriage frame 12 the bell 2T, attaching it by t e usual central pin. I attach also to the carriage frame 12 the frame extension 76, by means of the screws 7 7. This piece 76 carries upon it the inwardly-projecting pivotpin 70. Rocking upon this pin 7 1s the trip-lever 69, which projects u wardly into the path of the pin GS carrie by disk 67, but upon a plane that will enable it to clear the shorter pin 14 carried by the said disk; and this trip-lever carries near its opposite end the lug-pin 71. Rocking also upon the pin 70 is the hammer-stem 72, bearing the bell-hammer 26, the said stem 72 being engaged. by the lug-pin 71 before mentioned. Then it is time for the signal to be given, the pin 68, projecting from the disk G7 angularly adjustable relative to the toothed wheel engages with the trip-lever Q9, which is thereupon pressed downwardly By the lifting action of the lug 71 upon the stem 72 the'bell-hammer is thereby raised. The pin 68 then passes on, the trip-lever 69 is released, and the bell is struck by the bellhammer.

T he means whereby I render the machine inoperative are described t-hus: I attach to the carriage frame 12 by means of the screws (il the frame extension 22 as shown. The

carriage frame 12 must be imagined as bearnecticn or blade-piece 3, a convenient construction of which may be fairly represented by the end-view shown. This iece is as hing as the platen or longer, and its axis lies parallel to that of the platen. Attached to the piece 3 and rocking upon the same arbor 7 therewith as a unit, is the lever 1, which projects into the path taken by the pin 68. From one of the t pe-bars 78 as for instance from the one mar (ed 78', I remove the type and substitute instead the blank head 79, which is of a shape, size and material adapted to clase the printing point against any further printing in such a manner as not to injure the type nor the ribbon mechanism. This type-bar has the usual axis 81. and is supported in the usual manner upon the frame 41. such manner varying with the different makes of machine, as will be understood. This swinging bar 7 8 has connected pivotally thereto at 80 one end of the connecting piece 82. the latter provided with the projection 2. The bar 78 may be one that is added to the machine for this one use; or it may be chosen from among the typebars in the machine that are seldom or never used. It would preferably be stationed at about the point central between the ends of the main frame 41 of the machine. Vhen. it is time for the machine to be rendered inoperative, the pin 68 acts upon the lever 1, which in turn rocks the universal connection or blade-piece 3 backwardly against the projection 2, whatever the lateral position of the carriage, thus raising the blank head 79 against the printing point and holding it there until the said pin clears the said lever. It will be clearly seen that during the time the said blank 79 is in this raised position, no further printing can be done, the type in each case striking idly upon the blank. The piece supporting the blank need not be a typebar, nor the part operating it a typebar connection. The blank head may be made of any material, but I prefer a cushioning material like felt or leather. Y

I will now describe more particularly the use of. my mechanism. Suppose I wish to leave a margin at the b ttom of my sheet equal to eight single lne-spaces, or four double ones: I bring my periphery with its' indices around until the numeral 8 is Well within sight; I then loosen the adjusting or binding screw 18, turn the disk 67 until the adjustment pointer 16 thereon lies opposite the said numeral on the periphery, and tighten the screw. My mechanism will now always give a preliminary eye-signal when the bottom of the sheetI is approaching; and when the paper-sheet is finally advanced into the last line position` it will ring a bell, advising the operator that the current line is the last line to be printed upon that sheet. Ifthen the operator disregards this signal,

at the next movement forward of the sheet the machine will be rendered inoperative, and he can do no more printing. If for any reason he wishes to print an additional line upon the sheet, he has but to turn the platen forward a line or so as to carry the pin 68 beyond the lever 1, and then turn the platen backward into position, and his machine will be once more rendered operative. An-

other means of adjusting the meclianism'- without the use of the pointerl may be employed, the indices-bearing periphery being turned until the numeral 8 (say) comes opposite the pointer 34, and then the loosened disk 67 bein turned forwardly until the bell rings, an tightened.

I show two typical modifications of my more specific invention as described herein, in Figs. 3, 3, l and 7. In Fig. 3 a toothed wheel 11, is attached to the platen arbor 13 and turns as a unit therewith, whereas the mutilated toothed wheel 5, having attached thereto the rotary parts as shown in my figures before described. turns loosely with them upon the said arbor, the driving wheel 11 in this case corresponding to the driving Wheel 11 of Figs. 1, 2 and 6, and the mutilated gear 5a driven thereb corresponding to the mutilated gear 5 o Figs. 1, 2 and 6. Instead however of the swinging paper-feeler 28 shown in Figs. 1 and 5, and the train of parts giving the same control of the said drum, I show in this modification a paper-feeler directly connected with the drum and revolving therewith in an orbital path. This paper-feeler 28a is borne by an arm 32 Iixedly attached to the drum 6, and extends laterally from said arm, a laterally extending slo-t in the papertable 8 giving passage to the said aperfeeler past the paper-support in the a sence of the sheet. When the sheet covers the said slot the paper-feeler is detained thereby until the end of the sheet passes the slot. As a consequence the drum 63L is detained. Vhen the sheet-end releases the paper-feeler, the arm 32, acting as a weight rotatively upon the drum, rotates it forwardly, bringing the toothed wheels 5a andl11a into mesh.

.Henceforth the drum rotates in unison with the platen until the toothless portion of wheel 5a discontinues t-he connection, during such engagementI performing its indicating functions as explained in connection with Figs. 1,2, 5 and 6. In my Figs. 4 and 7 an arrangement is shown in which the paperfeeler 28b is also made rotary, but upon the axis 29; and it is provided with foldback means essentially like those provided for the paper-feeler 28 inFig. 1, the, axis 29'J here correspondingr to the axis 20 in Fig. 1` the pin 23b to the pin 23. the shank itself of the piece 28"to theluar 65andtbeleg 24. of the yoke 36 corresponding to the stop 24 in limit-ing the movement of the part 28 on the pin 23". The fold-back paper-feeler device as shown has here very clearly two uses, the one being to permit of a backingup movement of the sheet at any time, and the other, to permit of the closer stationing of the axis 29b relatively to the axis 13 than would otherwise be possible. Under certain conditions of crowding, it would have the same two uses in Fig. 1, as will be readily understood, paper tables sometimes sustaining more crowded relations with the platen than that shown in Fig. 1, and the necessity for providing for every possible backing-up movement of the sheet being the same in the one case as in the other. One of the objects of my Figs. 4 and 7 is to illustrate more clearly both these uses. For in a mechanism of this character, provision must be made for every possible backing-u movement of the sheet, and for the handllng of wrinkled sheets and sheets having broken surfaces. Suppose for ,instance that the sheet 45 as shown in Fig. 1 is advanced until the .part 28 is released by it, and that then the sheet is backed upit will be seen that if the paper-feeler 28 contained no fold-back joint, it would be pressed backwardly through its slot ahead of the edge of the sheet until it cleared thc slot` and then would lie upon the sheet, but pointed backwardly. Suppose now that the sheet is again advanced--ordinarily the end of such a papenfeeler would lide lightly over it to the edge, without inci ent; but if the sheet contained a wrinkle or roughness, the backward-pointing paper-feeler 28 would be likely to snag and tear the sheet. By providing the paper-feeler 28 with ilexion means and a limiting stop as shown, I completely avoid the danger. The action of such a jointed paper-feeler willbe the same whether completely rotary, as shown in Figs. 4 and 7, or only oscillating. as shown in my other figure. The mechanism would be operative using a paper-feeler 28 or 28h not provided with the joint as shown. It is to be noted that the paper-feeler 28 or 28b need not be of the formshown, but may be iven a Widely different form, and the Hexion means may vary widely in form, asis plainly illustrated in my Figs. 1 and 4.

The purpose' of my lug 63 and stop 62 is to provide for a backing-up movement of the 'pin 14; and the levers 69 and 1 are supplied wlth a similar provision, each in its own way, to provide for a backing-up movement of the pin `68. Other provision could be made for such a backing-up movement instead of the provision shown.

One of the objects in presenting the construction that is represented in Fig. 4 is to show a means different from the weight means shown in Fig. 1 for bringing the unbroken portion of the periphery of my mu- Vvated wheel 1nto engagement when it is time therefor. In Fig. 4 the friction-segment 40 added to the drum 6b bears frictionally upon the friction-periphery 37 turning with the platen. So long as the part 28b is held in restraint by the sheet of paper, the drum 6h and mutilated gear 5* are prevented from turning, and the friction-periphery 37 slips upon friction-segment 40 in revolving. When, however, the end of the sheet passes the part 28", releasing the latter, the frictional engagement of the friction-periphery 37 with the friction segment 40 operates to advance the drum 6b and the mutilated gear 5b suiciently to cause engagement of such gear with the wheel 11". I do not necessarily limit myself with regardto the precise' form of frictional engagement which may be used in this embodiment of my invention to carry the mutilated gear into engagement.

The indices used are preferably carried upon a periphery and revolve upon an axis, as shown, but my invention is not necessarily limited to any particular form of the carrier nor to any particular position of the indices thereon. I preferably employ indices involving no memorizing nor mental calculation on the part of the operator, such as numerals in a descending series, although I do not limit myself to the employment of any particular kind of indices. I do not specify any particular sheet-position as associated with the giving of` my visual signal-the signal can be given earlier or later, within the range of my mechanism, as will be understood. The visual signal may be used alone Withoutthe indices, and the indices alone Without the visual signal, or both indices and visual signaling means may' be omitted and the bell signal alone used, or the means rendering the machine inoperative, alone, or either it or the bell signal used alone with the indices, or with the visual signaling means, or with both.

The preferable form of my invention is that illustrated in Fig. 1.

It is to be noted that although I show my sheet-controlled controlling means as embracing a paper table provided with a slot or opening therein and a paper feeler 28 having its path through the slot I do not limit myself thereto in all cases.
