TYPE-WRITING MACHINE.

SPECIFICATION forming part ot' Letters Patent No. 472,692, dated April 12, 1892.

Application tiled July 1l, 1891. Serial No. 399,117. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE C. BLIcKENs- DERFER, a citizen ot the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type-Triting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others 1o skilled in the art to which it appertains to make and use the same.

This invention relates to type-writing machines; and it consists in certain improvements in the construction thereof, as will be hereinafter fully set forth, and pointed out in the claims.

The particular class of machines to which my invention relates is that having a typewheel, and the particular type of that class 2o is that construction of type-wheel machines shown in several pending applications for patents by ine-such, for instance, as Serial Nos. 390,488 and 390,489, filed April 25, 1891., and Serial Nos. 316,588 and 316,591, tiled July The leading features shown in the accompanying drawings are closely allied to those shown in the applications Serial Nos. 390,488 and 390,489, and the present machine may be 3o treated as a modification of the machines rep- 1 resented in those cases.

The accompanying drawings illustrate the present construction, as follows: Figure 1 is a perspective View of the machine complete. Fig. 2 is a top or plan view of the machine. Fig. 3 is an elevation, looking at the left side of the machine. Fig. 4 is an elevation, looking at the right side of the machine. Fig. 5 is a plan view of the bottom of the machine 4o with some of the springs 7L broken away. Fig. 6 is a longitudinal vertical section on the line 6 6 in Fig. 2, looking in the direction of the arrow thereon, with parts beyond in elevation and the paper-carriage omitted; Fig. 6, a perspective View showing in detail the position of the feeding-pawl and checkingpawl when in operative contact with the rack of the carriage. Fig. 7 is a transverse vertical section taken on the line 7 7 in Fig. 6, looking 5o in the direction ofthe arrow. Fig. 8 isa transverse vertical section, partly in elevation, on

the line 8 in Fig. 6 of a portion of the machine, the scale being enlarged. Fig. 9 is a plan or top view of the lowery rear portion ot' the machine with upper parts removed. Fig. 10 is a front elevation of the right-hand endv of the paper-carriage. Fig. 11 is a transverse vert-ical section of the paper-carriage on the line 11 11 in Fig. 10, looking in the direction of the arrow. Fig. 12 is bottom view of a por-l tion of the base-plate of the paper-carriage. Fig. 13 is a side View of a portion of one of the key-levers and shows its relation to the frames P and R. Fig. 14 is a perspective of the feed-lever S S detached from the machine. Fig. 15 is a side view of the lockingbar C detached from the machine. Fig. 16 is a top View of the type-wheel shaft D detached from the machine. Fig. 17 shows the pawls E and E in perspective ldetached from 7o the machine. Fig. 18 is a like View to Fig. 7, showing a changed position of parts and with the spacer-key L removed. Fig. 19 is atop view of the ratchet D3 removed from the machine, showing the guard-plate d. Fig-20 75 is a detail showing the connection between the space-lever and the lever which actuates the pawls; also, the cam for operating said pawls.

Like letters and numerals of reference indi- 8o cate like parts in all the figures.

The construction and operation are as follows:

A A A2 mark the frame-work of the machine.

A3 is a comb or front frame-plate, having slots a2 to receive the type-keys. lMis a comb or vback frame-plate, also having slots m to guide the key-levers.

A4 is a comb or bottom frame-plate, having 9o slots ce to hold the lower ends of the keylevers. A5 is a frame strip or bar, under which, are clamped the fixed ends of the key-lever springs 7i. A6 is aframe-bar which lies along under .the ends of the key-levers and keeps them in place. (For the parts A4, A5, and A6 see Fig. 5.) The plate A4 has a back extension a5, like a bracket, to serve as a rest for the feeding-pawls S2. (See Figs. 5 and 9.)

H H, dac., are the type-key levers. These levers are all substantially alike in form, dit'- fering in length, so as to form banks ot' keys,

IOO

and differing in direction to give them proper spread at their key ends.

Y dotted lines in Fig. 13.

L is the spacer-lever, which is substantially like the longest key-levers. In Fig. 13 the inner part of one of these key-levers is shown. It has at its eXtreme inner end a hooked toe h5. Back of this is a heel h2, and above this are two bearing-surfaces 71' and hl. Of these bearing-surfaces the ones marked h2 are alike in position, while those marked 77,4 vary in position, so that in a line of keys they will be graded consecutively. This is indicated by The typekeys are arranged in two like groups, one on each side of the middle line of the machine, andthe spacer-key is located between the two groups. These keys pass through the slots a2, m, and d and hook under and are thereby pivoted 0n a common rod ll, which runs lengthwise of the machine at its lower rearward part. The spacer-key L is arranged in the same manner as the key-levers. On the shaft H are also pivoted three swinging frames P P and R', the former of which contact with the bearing-faces h3 of the two groups of keys, respectively, and the latter contacts with the bearing-faceshL1 of all the keys of both groups; but the spacer-key L is so formed as to escape these frames entirely. (See Fig. 7.) The frames P each carry a rocking arm P, and these arms have gear-teeth at t heir upper ends, meshing with like teeth on the arms F, which are journalcd on the shaft D5. lllence when the frames P are rocked the arms F are also rocked. The frame R carries arm R, which has gear-teeth at its upper end,meshing with like teeth on the pawl-arm E E2, journaled on the shaft D5. Hence when the frame R is moved the pawl-arm E E2 is moved. (See Figs. 8 and 17.) The gear-teeth on the pawl E E2 and the part R, which engages said pawl, are arranged in an arc having the same radius as the arcs of teeth on the segment-carrying arms F. Hence when the pawl is moved by the part R it will move in exact consonance with the arm F.

On the shaft D5 is a T-formed sleeve T, and in this sleeve is held the type-wheel spindle D. This spindle has an extension or bail d1, which is vibrated therewith and when vibrated engages with a locking-bar C for a purpose hereinafter described. In the present instance this extension d10 is formed by bending the spindle D at right angles to the vertical part. It can be then bent again at right angle CP2 to the horizontal part to form a rectangular loop (see Fig. 1G) and passed through the shaft D5, which'will serve as a guide and also hold the spindle against rotation. (See Fig. G.) The down movement of the part i12 is limited by a stop '6113. The type-wheel D is held on a spindle D between a collar C17, fastened by a pin d2, and a catch (Lwliich engages a groove at the upper end of the spindle. Between the collar dT and the upper end of the sleeve T on the spindle D is journaled loosely the pinion F2, and it is held against longitudinal movement by a groovef therein engaging with a lip t on the sleeve. (See Fig. 8.) On the upper part of the hub of the pinion F2 is fastened by a screw-collar d6 a ratchet-Wheel D2 and eccentric or heart-shaped ratchet D2, so that they will move with the pinion. A crank post or pin d is attached to the ratchet D3, passes through the ratchet D2, and engages the wheel S. As the shaft or spindle D has no rotary movement, the wheel D is propelled rotatively by the pin d. By means to be explained farther on the spindle D is moved longitudinally, and it carries the wheel D-with it, so as to bring the different fields of type on the wheel into position, and .in thus moving'the wheel slides on the pin d', which is of proper length to permit of that movement. In Fig. 1S the wheel is shown thus moved outwardly. The wheel D can be quickly removed from the spindle by removing the catch CZ from the groove in the end or the spindle. Axial motion is imparted to the pinion F2 by segmental racks F, carried on the arms F, which, as before explained, rocked by the arms P and frames P through the action of the key-levers Il. Only one of the frames P and arms P will be moved ata time, and which one it` may be will depend whether the key-lever depressed is in one group or the other that is, on one side or the other of the middle line. When in normal position, the two segmental gears F F have their upper ends abutting against the'bulfer a3 on the frame-piece A. As soon as one or the other is moved in the manner above described it falls away from the buffer and of course rotates the pinion. This action of the pinion rolls it down the stationary segment F,

and the reactive effect keeps the stationary segment F against the buffer; but the shaft D5 is rocked and the spindle D is tilted forward, carrying the wheel D and ratchetsD2 and D3 with it. All these parts D D2 D3 partake of the rotary action of the pinion, as well as the tilting movement of. the spindle. So, it will be seen, the type-wheel has imparted to it by the depression of any of the key-levers ll a simultaneous axial and vibratory movement; but the axial movement mustbestopped as soon as the desired letter is brought into proper position for impression, and the vibratory movement must be continued until the type is impressed. The means for effecting this result are the frame R', the arm R, the pawl-lever E2 E, and the key-lever H. It will be remembered that the key-levers H have bearing-faces h4, which act upon the frame R, and that these faces in each group of keys are graded as to their distance from the frames. The effect of this is that each individual key-lever of each group will contact with the frame R after moving through more or less space than any of the others of its group. The characters on the type-key levers and the corresponding type on the type-wheel are so arranged relatively that when any keylcver is depressed its corresponding type will be positioned for action, and the bearing-face IOO IIO

haof that key-lever is so distanc'ed from the frame R that as soon as its correlated type is positioned the key-lever will bear upon the frame R and move it down. The arm R Aot said frame then will move the pawldever shaft M and the parts carried thereby until the type-wheel is brought against the platen B' on the carriage B, and thus impresses the type upon the paper on the platen. The ratchet D2 is provided with as many notches as there are key-levers I-I, which number is also the same as the number of type in each iield of type on the. Wheel D, and the ratchet D2 has a like number of teeth. The ratchet D2 is a concentric disk, and hence its teeth are equidistant apart; but the ratchet D3 is slightly heart-shaped andeccentrically mounted on the pinion F2, and its teeth increase in length in proportion to their distance from the axis of the ratchet.

IVe have seen that the pawl E2 E remains stationary until a type is positioned and that the ratchet D3 moves down as it moves axially, and the downward movement is produced by the rotary movement of the pinion which carries the ratchet, and consequently the tWo movements are proportional one with the other, so that it follows that the teeth of the eccentric-ratchet will, although moving in different paths, all pass the point of the pawl E2 E at like distance from it, so that the said pawl will have to move no farther to engage one tooth of the ratchet D2 than another. The pawl E2 E is heldso as to just barely escape the passing teeth, so that its movement necessary to engage a tooth is as slight as possible, and it will therefore engage the proper tooth practically instantaneously on the positioning of the type.

Then the type to be positioned has to be moved through considerable distance, the parts acquire considerable momentum, and when the pawl E2E engages atoot-h there may be a rebound. To obviate this, I provide a pawl E', which engages the ratchet from the opposite direction diametrically and coincidently, or practically so, with the pawl E2 E. These pawls E2 E and E grasp the ratchet D3 somewhat like a pair of pinchers and hold it against reaction. The form of the pawl E is shown in Fig. 17 clearly. Itis pivoted loosely on the shaft D5, and its lower end rests in a notch in the comb A2, (see Fig. 1,) and it is held there iiexibly-by a spring e2. (See Figs. 7 and 1S.) Its upper end stands in as close proximity to the ratchet D3 as possible, and it engages the ratchet by the ratchet being pushed against it by the pressure of the opposite pawl E2 E, and as soon as it is engaged with the ratchet it moves down with it, overcoming the spring e2. (See Fig. 1S.) The pawl E is not required to act except when the axially-moving parts have to move a considerable distance, and thereby acquire considerable momentum, and I have lfound. by practice that it is better that it be not used when the axial movement is slight, and therefore I have applied to the apex of the lobe of the ratchet a shield di). best illustration.) This shield is 'on top of the ratchet and stands or ledges out over the teeth and holds the pawl E off from the teeth, while it permits the pavvl E2 E, which is made shorter at its engaging end, to engage those teeth covered by it, as seen in Fig. 18.

To insure absolute accuracy in the positioning of a type by reason of any lost motion, the ratchet D2 is provided. This ratchet is a concentrically-arranged disk having radial teeth, Which are engaged by thel fixed horn-like pawl M2 as the type-wheel is brought down to the platen (see Fig. 18) and steadies the Wheel against trembling and against any lost motion that may exist in the parts. In order to position a field of type, the Wheel D has to be moved longitudinally of the shaft,

vand then it must be held against further longitudinal movement While being operated. The means for effecting this resultare as follows: The spindle D is movable longitudinally and it carries the Wheel with it. The spindleis kept dovvn to normal position by the spring DX, (shown best in Fig. 6,) and it is moved up by a lever 0, which is pivoted on the rod I-I. This lever is under the control of two levers I and K, which lie paral- (See Figs. 19, 8, and 4 for j ICO lel with the front plate A2 and extend out at the side of the machine through a slot which has a stepped bottom t lo for regulating the degree of depression of said levers, and then turnup and are provided With iinger-buttons I and K. There are shown in the present instance three ields of type on the type-wheel. One is in action when the spindle is at normal position-that is, down. The next field-the middle one-is brought into action by the use of the keyI and lever I', and the lower field is brought into action by using the 'key K and lever K. There Will be as many such keys and levers as there are elds of type more than one. These levers raisey the pivoted lever O, and it pushes the spindle D up one, tWo, or more points, according to which key and lever is operated, and this moves the Wheel one, tWo, or more points, so as to bring the proper field of type into action. The means for holding the Wheel at any of these points of action and i'or preventing any longitudinal movement of the Wheel when in action is the locking-bar C, which has notches c c2 c2, which engage the bail of the spindle when it is tilted, whether it be at normal or at one of its elevated positions. This locking-bar C is seen clearly in Figs. 3, 4, 6, '7, 8, and 18 in its proper place, and in Fig. 15 detached from the machine. It is journaled loosely on the shaft D5 and is flexibly held against pivotal movement by the spring C (see Fig. 6) and is limited in its movement IIO by the frame-piece A' crossing as a stop. Whenever the type-wheel is tilted, the bail of its spindle enters one of the notches c' c2 c3, according .to its position, and is held against any possible longitudinal movement. When the parts are in their normal positions, the bail is free from the locking-bar and the spindle can be moved longitudinally. The changed position of parts (shown in Fig. 18) shows the middle field of the type-wheel in action and the spindle engaged by the middle notch c2 on the locking-bar and the lockingbar tilted up, with the bail of the spindle and the lever I depressed. Y

The type are inked after being positioned and while moving forward to an impression. This is effected by an inking-roller G', hung on a yielding arm G in the path of the typewheel, which is pushed aside by the type- `wheel, and the ink-roller thereby applied to the positioned type. The arm G is hung on the frainepiece A2 on a pintle g2 and is made quickly reactive by a spring g, and its forward movement is limited by a set-screw g3. The arm G is quickly detachable from its hanger, as it has an open hooked slot g', which hooks over the pintle g2, and can be disengaged quickly by drawing the armback and then downward bodily.

The means for feeding. the paper carriage are as follows, (see Figs. 5, 6, 62, 7, and 9:)

On the rear edge of the base-piece B of the carriage is a ratchet b, having rectangular indentations, and on the rear part of the frame A, back of the carriage, are two pawls S2 S3, one of which S3 is pivoted at 85 to the frame-work, and the other S2 is pivoted to the pawl S3 at .s4 and is reacted by a spring s'. The pawl S2 has a free action on its pivot and is counterweighted, so that its head will keep erect. Its tail end is supported on'a rest s3 on the rear part of the frame-work, and its head when in normal position rests on the bracket a5.

In Fig. 6 the pawls are shown in normal position, or when out of action, and in Fig. 6n when in action upon the carriage- Normally these pawls are not `in engagement with the carriage; but as soon as moved the pawl S2 enters its point between the teeth b on the base-piece B of the carriage and is prevented from passing above by an extension S7, which strikes upon the plate B back of the ratchet. (See Fig. 7.) As the movement of the pawls continuesupwardthehead of thepawl S2movcs forward and carries the carriage with it, and when the pawls have completed their upward movement the head of the pawl S3 has also entered anotch of the ratchet. The position is then as shown in Fig. 62, with both pawls in engagement. The carriage is then immovable. The forward movement of the carriage is effected wholly by the forward movement of the pawl S2 as it moves up, which forward movement is effected by its pivot s4 moving in the arc of a circle having the pivot s3 as a center. The degree of forward -movement the carriage against undue movement.

is just equal to the spacing of the ratchetteeth b, so that the carriage is moved one notch at a time. The pawl S3 acts only to lock The means for moving these pawls is the arm S', forming a part of the lever S S', which lies directly below the pivot-point s4. The lever S S' is shown detached from the machine in Fig. 14:. It is journaled loosely on the shaft H and is movable by the action of any of the keylevers I-I or the spacer-lever L. The spacer-lever L is journaled to the shaft I-Ibetween the ears of lever S S' and is provided with a heel L', which engages a lip or projection S10 on the pawl-operating lever S S when the spacer-lever is depressed to move said lever, the pawls connected therewith, and the paper-carriage independently of the key-levers.. As has been seen above, a movement of any of the key -levers H will rock the shaft D5, which is journaled on points d3, fixed in the frame-piece A. On this shaft D5 is secured a cam Q, preferably eccentrically faced and which rocks with the shaft. This cam has two faces qand q'. The face q is of gradually-increasing radius, the shaft D5 being lthe center of the different radii. The face q' is on an arc of a circle, the shaft D5 being the center. Whenever the shaft is rocked to impress the type-wheel upon the paper, the cam Q acts upon a roller s on the upper end of the pawl of the lever S S to depress that end and raise end S' to operate the pawls S2 and S3 to respectively propel and stop the carriage. This movement of the pawls is accomplished by the face g of the cam Q acting upon the roller s until the face q is reached. This face, being on an arc having the shaft D5 as a center, will slip over the' rollers Without depressing the arm any further and at the same time by means of said lever hold the pawls in place until the motion of the shaft is reversed.

It will be noted that the spacer-lever movesk fewer parts than the type-key levers, and hence will naturally move easier; but it is desirable thatthis key have the same resistance tothe hand of the operator as the other keys. This may be accomplished by making its spring h' stiffer than the others, or a supplementary spring Z may be used.

As above stated, the pawls S2 S3 when in normal position are wholly disengaged from the carriage and it is free to be moved manually in either direction. I-Ience when wide 0r extended spacing is wanted or when the Acarriage is to be gigged back to start a new line it will be moved manually. A pointer or guide B3, which lies over the platen, serves to indicate to the operator the point where the type will be impressed upon the paper, so as to aid him in placing the carriage in the position desired. This pointer B(i is a curved bar, which is fixed to the comb-plate M, as clearly seen in Figs. I, 2, 4, and 6. At the right hand or rear end of the carriage is a warning-bell B4 and a hammer b4 for striking the bell, which IOO IIO

is pivoted to the end frame-piece B and is moved to strike the bell by the lower end of the pawl S2 striking against the hammer b4 as the carriage passes said pawl.

In order to relieve the operator of care in placing the carriage always in the same position at the beginning of a line, so as to make the lines register or align vertically, I have provided a variable stop mechanism, which can be used ornot, as desired, and when used may be set so as to align the lines more or less distant from the left-hand edge of the paper,

and thus give a margin of more or less width,

and it can be quickly changed, so as to change the width of margin at willand quickly when desired. This stop mechanism consists of a serrated catch-bar b2, placed diagonally across the lower side of the carriage-base B near the front or left-hand end of the same, (see Figs. 5 and 12,) and a variable-stop lever N,Which is pivoted on the under side of the frame A and extends out at the left side of the machine. (See Figs. 2, 3, 5, 6, 7, and l2.) By swinging the outer end of this lever close up to the side of t-he frame the point n at the inner end will entirely escape the catch-bar and the carriage can be moved freely; but by swinging the outer end of the lever N away from the machine the point n will be carried in front of the catch-bar b and will engage with it and stop the carriage. The degree of extension of the lever N will regulate the point of stopping, because the farther out the lever is swung the nearer the point n will be carried to the inner end of the catch-bar b', and hence the carriage will be stopped earlier in its rearward movement or gigging, and hence the wider the margin will be. It is often desirable to stop the traverse of the carriage at certain positions in the line or at one or more points in the line during the motion toward a uniform terminal point, particularly in such work as making out bills of account when a column of figures is to be printed at the righthand side of the sheet with a space between it and the items printed at theleft-hand side of the sheet, or in tabulating and other like work. Unless some special stopping device is provided the operator is compelled to exercise great care io print the amounts, so that the units, tens, hundreds, dac., will be aligned vercally, so as to be summed u p easily. The mechanism provided for this purpose is seen in Figs. l, 2, 3, 4, 5, and l0, and consists of an adjustable stop on the frame of the machine and a variable-catch mechanism on the papercarriage. The adjustable stop consists of a bar U, on which is a lug it to engage the catch mechanism. This bar slides in ways below the carriage and extends out at the side ot the frame and is bent at the end, so as to be easily grasped by the hand. It has notches u on one side, which engage with like teeth u2 on the fixed part of the machine, and is held exiblyin contact therewith bya spring u2 on the opposite side. The bar U can be moved longitudinally easily by the hand and can be set so as to fix the lug` u at various points. The catch mechanism on the carriage consists ot a series of keyed catch-bars V V2, duc., pivoted in a bracket b5 at the right-hand end of the carriage. These catch-bars are held up by springs o (see dotted line in Fig. l0) and are depressed by pressing with the linger on the key of the lever. Each catch-bar is provided with a catch-notch 'u on its under side, and the position of the catch-notch on each bar is different from that on the others, and they are so arranged as to be graded from the end of the carriage. Thus the notch on the bar V is farthest from the carriage, and on V2 next farthest, and on V3 next, and so on, bringing the notch on V2 the nearest.l The keys of these bars are numbered l 2 3, dac., to 6. Let it be supposed that the operator is making out a bill of account. He will set the bar U so as to bring the lug u to the point he desires. This determines the position on the paper of the unit-line of the coluin'n of iigures to be printed. He will then print in the item on the left of the sheet and then move the carriage so as to print in the account on the right of the sheet. In so moving the carriage he will take hold ot it with the right hand at the right-hand end, and if the amount to beentered contains three digits he will depress the key having the number 3 thereon, and the catch on that bar will engage the lug u and stop the carriage in position to properly position the left-hand digit of the amount. He will then release the catch and operate the keyboard and print in the amount. lt the next amount to be entered contains four figures, he will depress catch-bar 4, and the carriage will bestopped one notch earlier than before, and hence the figures of that amount will have their units under the units of the amount above and their tens under the tens, and so on. So it will be seen that vall amounts printed in will have their units, tens, te., aligned vertically on the paper. The carriage will always be stopped in exact position for the printing of the left-hand digit in proper place. The disposition of the parts of the carriage-stopping mechanism, as shown, is an important and valuable feature of the invention, for by placing the stop on the frame of the machine and the variable key-actuated catch on the carriage the operator is able to vary the catch, as desired, and move the carriage forward simultaneously by a single movement of one hand, while when the stop is on the carriage and the variable catch on the frame, as shown in Figs. l0 and l1 of my pending application, Serial No. 398,672, the use of one hand to move the carriage and the other to manipulate the catch is necessary. In machines having a spring-actuated carriage that isted forward by an escapement or releasing device the latter construction is desirable; but where the carriage is free to be moved manually independent of itsfeed mechanism, as here shown, it is undesirable and inadequate.

IOO

The means for rotating the platen step by v step to space the lines is the paWl-and-ratchet device B7, which may be of Yany desired construction. The construction here shown is not new in its details and requires no special description. The means for rotating the platen continuously to draw in a new sheet of paper is the hand-wheel rlhe means for 'holding the paper closely to the roller or platen are the curved guide-fingers BS and the roller B9, and as these parts may be of any desired construction and, as shown, possess no new features further description is unnecessary. By t-he term variable stop or catch mechanism as used in this specification I Wish to be understood as meaning a mechanism which will stop the carriage at varying points, and by the term adjustable stop I Wish to be understood as meaning a stop that can be shifted to varying points. The adjustable stop determines the location of the column of figures on the paper, and the variable-catch mechanism determines the point where the first numeral of any amount to be vprinted shall be'located within said column.

I do not herein claim an attachment for type-writing machines consisting of a series of stops arranged side by side and at a letterspace distance apart for the purpose of determining the stopping-point of the carriage and enabling such point to be varied at ,each

successive line, as said subject-matter is embraced in an application, Serial No. 410,893, filed November 4, 189i; nor do I claim herein the combination of a carriage, astop mech- 'anism `for arresting' the carriage at different points as it moves to the left, and a key mechanism for manipulatingT said stop mechamsm, nor the combination'of a paper-carriage and a columnating attachment consisting of `a variable-stop mechanism controlled by keys used I Wish to be understood as embracing all `mechanism'wherein the stop is variably `positioned by the pressure of the hand or tinger upon a yielding` part or parts in contradistinction to a mechanism which maybe variably set or adjusted, such as a pin in a hole or a collar on a rod, o.
