Specification of Letters Patent.

Patented Feb. 18, 1913.

Application led May 27, 1912. Serial No. $219,958.

To all whom t may concern:

Be it known that I, WILLIAM J. NEIDIG, a citizen of the .United States, residing at Madison, in the county of Dane, State of IVisconsin, have invented a certain new and useful Improvement in Type-'Writing Machines, of which the following is a speciiication, reference being had therein to the accompanying drawings.

Certain principles and features of my invention as described herein are included within the invention which is described and generically claimed in my co-pending application tiled April 20, 1908, Serial No. 428,212. y

One of the objects of my general invention is to indicate to the operator of a typewriting machine the decreasing distance from the current printing point to the bottom end of the sheet, or to another point on the sheet, during the progress of the sheet, and this without preliminary care on his part, automatically. This function I believe has never before been performed, but is novel to my generic invention.

Additional objects are to supply the operator with other indicating means, comprising improved visual, audible and machine-lock .signals given sheet-positions.

The present embodiment o-f the invention has as features certain novel co-mbinations of sheet-controlled elements adapted to render the invention more useful under the va.- rious conditions of practice, as will be explained. l

In the drawings,-Figure 1 is a side elevation of portions of a type-writing machine carriage, partly broken away, showing my invention as applied thereto, certain portions of the main frame also being indicated. Fig. 2 is a plan view of some of the parts shown in Fig. 1. Fig. 3 is a crosssection on the line 8-3 of parts shown in Fig. 4. Fig. 4 is a view chieiiy in section on at predetermined the line 4-4 of Fig. 3, looking in the direction of the arrows, and showing the drive mechanism actuating drum 6. Fig. 5 is a side elevation of a portionof a type-writer carriage showing a modification. Fig. 6 is a pian view of the same. Fig. 7 is a side elevation re resenting another modification. Fig. 8 is a ront view of the same, the carriage being shown in section.

Referring to the drawings, the main frame of the machine is indicated at 4.1, and. the-usual carriage frame, movable laterally as in practice upon the main frame, at 12. In the carriage frame at either .end is jour'- naled platen arbor 13, which bears fixedly attached thereon in usual manner the typelwriter platen 10, whicl: A:s herein regarded is the principal feed-rci4 for feeding the sheet through the machine. The platen is .connected as in practice with usual linespacing mechanism, not shown herein, of any approved type. The paper-table for the support of the entering sheet is'shown at 8, the same being carried in usual manner upon carriage-frame 12. This structure is well-known to tho-se skilled in the art and need not be more fully described. Against the platen head 39 at the end of platen 10 is aiiixed inner shell 11 so as to rotate in unison with said platen head` and therefore with the platen to which the platen head is attached. Independently journaled upon platen arbor 13 is drum 6, the laterally extending peripheral portion of which over laps inner shell 11 and moves loosely' thereon. Drurrai 6 consistsof a peripheral or index-bearing portion, an upstanding portion, and a bushing portion, the upstanding portion being iXedly attached to the bushing portion 6. Upon the inwardly projecting pins 53 on said drum are journaled the belllevers 18 connected by means of the pins 1G with the friction-pieces 5. Springs T attached at one end to pins 4 on'said drum en-A igage at the other end with said bell-levers sleeve 21. Fixedly attached to said sleeve near one end is stop 15 and Xedly attached near the other is paper-feeler 28, the parts. being so mounted that a short slot or opening 4 in paper-table 8 lies underneath the paper-feeler, and the end of stop 15 lies in the vplane of projection 14. The spring 151 tends to move stop 15 out of the path of said projection and paper-feeler 2B into said slot, one end of said spring being attached to carriage frame 12 and the other end engaging upon said stop. Carriage traine 12 bears also the inwardly extending pin 22, on which is journaled hub 23 bearing hammer-stem 24. Lever 25 having a weighted portion 31 is also journaled on pin 22, but outside of the plane of projection 14 on the drum. Lever 25 bears the pin 29, which engages upon said hammer-stem. An outwardly extending pin is carried by drum 6 in such radial position as to engage with lever 25 but not to engage with stop 15. Pin 36 may be screwed into any one of the threaded holes 30", so as to engage with said lever earlier or later. Stem 24 bears bell-hammer 26 ailixed to the free end thereof, and is given a U-form, downward, outward and upward, for convenience in bringing it adjacent to the bell 27, supported from carriage frame 12 on central pin 32. Carriage frame 12 bears also the inwardly extending pin 40, on which is journaled hub 72 having a downwardly extending portion 43, a jointed lever-portion 1, and a leverportion 45. Said downwardly extending portion 43 and pin 40 may be regarded as 'representing similar parts on the carriage frame at the opposite end of the'platen, as will be understood, the said parts 43 being joined by the laterally extending part 42 so as to form a rocking bail-piece. The portion 42 of'this bail-piece is supplied with teeth 44 alternating with interdental spaces. Attached to the carriage track about midway laterally between the stationary frames '41 of the machine is the stop 48 having a toot-hed portion 49, the arrangement being such that when bail 42 is'rocked rearwardly on axis 40, teeth 44 will pass on either side of tooth' 49. Lever 45 is continued rear-r 'wardly, and rests by gravity against stop 47 bon carriage frame 12. Lever 1 is mounted in such a plane as will not engage it with

projections

14 and 30 aforesaid. Coperating' with said lever is projection 68 which *may be screwed into one or another of the threaded holes 68 in the upstanding portion of drum6 so as to be angularly adjust.- able on said drum. It will be understood that pin 68 has a radial position permitting itto clear lever 25 and stop 15.

The action of the mechanism is as follows: The sheet of paper 33 is placed upon the paper-table 8 inusualinanner and advanced toward the platen for entering into the machine. This act-ion carries the leading edge lof the sheet'under paper-feeler 28 so as to -raise said paper-feeler out of slotv4, the paper-feeler being light and suitably shaped and moreover projecting into the slot only a -short distance. This action rocks sleeve 21 and moves stop 15 upwardly until it lies in the path of projection 14, against the action et the light spring 151. All these parts are constructed as light. as possible so as to reducerinertia, and the spring-action is extremely light. It is found in practice that by such use of the leading edge of the sheet the operator is able to move the lightly poised stop 15 into the path of projection 14 without the exercise of additional care. The sheet will be advanced thro-ugh the machine by the platen as usual. The turning of the platen causes drum 6 to rotate, frictionmember 11 being in engagement with the cooperating friction-member 5 and acting drivingly thereon. This rotation of drum 6 will eventually bring projection 14 against stop 15 in its path. Drum 6 will thereafter be maintained in a stationary position during the presence of stop 15 in engagement with projection 14, and in this position it will remain until. the .bottom end of the sheet passes from under paper-feeler 28. Upon the passing of the sheet-end, paperteeler 28, no longer controlled by the sheet, and under the actuation of spring 151, will enter slot 4, and stop 15 will be withdrawn from the path of projection 14. Drum 6 under its frictional actuation will now be given movement simultaneous with that of the platen. I V

Since the end of the paper-feeler 28 must intersect the paper path so that the paperfeeler is always released when the end of the sheet isaiixed distance from the printing point, drum 6 mustfbegin its movement when the bottom edge of the ,sheet is a fixed distance from the printing point, and as the drumv maintains .always a line by line progress thereafter with the sheet, since it moves with the platen and the platen advances the sheet, it must bring always the same po-int on its periphery oppo-site pointer 34, attached to carriage frame 12, -when the end of the sheet attains any given distance from the printing point. This distance, .whatever it be, can be determined, and can be indicated by an index on the drum or index-carrier 6, so thatthe distance from the end of the sheet to the lprinting point will be indicated step by step from the time paper-ee'ler 28 is released by the sheet until the sheet leaves the machine, or as lo-ng as desired. The kind of indices employed, and thevunit of measurement, will be as may be preferred. I

prefer to use numerals for indices, arranged in descending order asshown in the drawing. It is ot' course 'immaterial whether the movable indices come to rest exactly opposite the stationary index or pointer, or whether the indices in themselves signify distance units, or indicate .the entire remaining distance to the bottom edge of the sheet or only part of it.

I usually employ for a stationary index a v'shield-pointer, that conceals one portion of the carrier from the operator, and the carrier itself is divided into two different-api bij sheet.

pearing segments, one of which is visible to the operator during the detained position of the carrier, and the other of Which is not visible but lies behind the shield-pointer in that position of the carrier. In my drawings I show the first named of these segments as containing no indices except the circular index 89, and by preferencel I color this segment black, and the second of these segments, which I cause to bear indices, I prefer to'supply with a ground of White. When the sheet end releases the carrier or drum, and the White index-bearing segment comes into view, the change from black to White attracts the operator-s attention and he knows that the end of 'the sheet is Within a given distance from his printing point. It is not essential that the White segment should come into view at the very first feedmovement after the release of the carrier.

` My audible and machine-lock `signals are given as follows: Atthe predetermined time after the release of drum 6 to move with the platen, projection 30 engages with lever 25, rocking the same upon pin 22 and through the engagement of project-ion 29 upon hammer-stem 24 moving the bell-haii1 mer 26 from bell 27 until pin 30 clears lever 25, Whereupon'hammer 26 falls by gravity against bell 27l and gives the operator an audible signal as to his sheet position. My machine-lock signal `is given as follows: At the predetermined time, project-ion G8 engages with lever l, thereby pressing lug .71 against lhub 72 and rocking said hub and the attached bail-piece 42 upon pin 40 until teeth Mare brought into engagement with tooth 49 on the machine frame. The carriage is thereby locked against lateral movement, the typewriter mechanism rendered inoperative, and the operator warned that itis time to remove his In case he should desire to print. another line upon that sheet he has only to turn his platen forwardly until lever l is released by pin 68 and then backwardly into the 'desired line position. The part-s on pin l0 will instantly return by gravity .into the positionA shown in Fig. l, releasing the machine for further use.

Itvvill be noted that the mechanism described can be backed up from any position and to any required extent. Stop l'is constructed-With a beveled head and with a double bend or offset in the shaft portion thereof. In case of bacltward actuation of projection 14 against stop l5 during the presence of the sheet under the paper-feeler, stop l5 will lift and permit projection le to pass thereunder, and when the projection comes to the oiiset portion of the stop the stop will be released by the projection and return intodetaining position. Backinguip of projo ion 30 past-lever 25 is provided tor through the giveway engagement of pin 29 upon hammer-stem 24, said parts separatl ing in such a movement and the Weighted portion 3l of said lever returning the parts into position after the passing of said pro jection. Backing-up of projection 68 past lever l is provided for, lever l bending backward on pin 7l, lug 70 separating from hub T2 so as to permit of the action.

I usually station my paper-feeler over the paper' table 8, and usually so ,mount the inciding with the plane of projection 14, but the position and form of these parts may vary, as may the speciiic form of means employed to give the iiidex-oa.rrier or drum movement after its release ey the stop. In the Figs. 5 and 6 I show a typical inodica` tion in the manner of mounting the feeler and stop part-s referred to. The index-carrier 6a and its frictional driving mechanism are es'- sent-ially the same as described hereinbefore. The platen head 39a is here made thicker in order to hold the'carrier farther away from the end of the platen and give room for the vaction of the parts. Attached to carriage frame l2 is frame-extension Ll2 bearing pin A 20a journaled upon which is bell-lever Se. One arm of said bell-lever has attached thereto the. paperfeeler 28 having action into slot 4.- in paper table 8. The other arm of said bell-lever is mort-ised. Pivoted in the mortise by means of pin 20d is stop 15a, lugs 62 and 63 limiting the movement of the stop upon said pin. A spring 152, one end of which engages upon said belllever and the other end of which is attached to frame- .extension 42, tends to roclr said bell-lever so that stop 15R takes a position out of the path of projection 14a and paper-feeler 28,a a position 'in slot Il. 1When the paper sheet is enteredl down' paper table 8, the leading edge thereof raises paper-feeler 28a out of slot 4,

thereby'moving stop lo into the path of projection '14, In this position the stop eooperates With the said projection to stop 'carrier 6a. When the end of the sheet passes the paper-feeler, stop 15e is Withdrawn from projection lll by theaction of springA 152 and the carrier thereupon begins its movement with the platen and thereafter performs its indicating functions, Whioh are identical with those. of carrier 6 of theearlier figures. y

In Figs. 7 and 8 I show how the pap'erfeeler may be mounted underneath the platen. Attached upon carriage frame 12, is frame extension 48 supporting the tivo ends of pin 20". Journaled upon said pin esv llfi

is sleeve 2la having tixedlv .attached thereto near one end the lever 64a and tixedly attached thereto near the other-end the lever 152. Lever 6l has attached thereto at its free end the upwardly extending paperfeeler 28a, having a path into the circumferential slot ft in the platen. Lever l5 is 75 parts that stop l5 will move in a plane cov journaled on pin 20c and having a lug 62 to limit its nmvement on said pin. Said stop is supplied with an ear 5l .tor one end o'l' spring 153, the other end ot the spring being attached to pin 55 on trame-entension 12S, said springtendingto pull said parts together. Normally the parts asslune the position shown in Fig. 7, with the paper-teel-er projecting into slot eta and stop 15b maintained ont. of the path of projection 14, spring 153 givingY the parts such position. The sheet entered as usual into the machine. Vvlhen the leading` end thereof encminters paperfeeler 28 it lifts said paper-teeler out of the paper path and moves stop 15b into t-he path of projection 14, which eventually will be stopped or -detained thereby as before. Upon the passing ot' the sheet-end the paperteeler will enter the slot, stop 15b will be retracted from projection 14 by the spring, and carrier 6 Will begin its movement with the platen, as before, and perform its indicatingr functions. Backing-up in these modifications is provided for. In case of stop 15n of 5 and (3, projection 1l lifts the stop out of its path, the lug 62 separating-t`rom lever G4 and permitting the movement. In the case of stop 15b in .Fins. 7 and 8, essentially the same Q action occurs, lug 62a separating from lever 15 when the projection 1s backed against said'stop and permitting; giveway movewill be switched into an open by-path out over the top of the feeler. In the embodiments shown in Figs. 5 and 6 the backingup bottom edge oi' the sheet will lift the paper-fecler out of its slot just as the leading edgewvill do when the sheet is entered. lt is to be noted also that in practice an operative member like drum G that is given movement with the usual abruptly starting,r and stoppingv platen tends to creep or drift in line-space direction lrelatively to the platen, and that the 'friction-drive. herein shown is especially adapted to check any such tendency, such movement on the part of the member acting; togglenvise to increase the friction between the member and its driver. j
