TYPEWRITER.

Application filed February 20, 1924. Serial No. 694,076.

do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked therein which form a part of this specification.

This invention relates to a typewriter in which the rotation of a cylindrical drum carrying in relief several rows of type, is controlled by the depression of a key of a keyboard, so as to bring the type or letter corresponding to the depressed key to the level of the paper on which the typing is to be done, and it relatesmore particularly to the general arrangement of the various elements of the typewriter.

The angular movements of the drum are controlled by an oscillating element or rock ing lever which is operated by means of various levers by depressing one of the keys of the keyboard.

The oscillating lever or rocker is looked after it has turned through a certain angle by means of two tappets or stops which are brought into two given positions by thev depression of a key. One of the said stops or tappets produces moreover the rotation of the rocker. c I

The part carrying the stops forms one side of a deformable vertical quadrilateral which is parallel to the front of the machine, and one of the stops or tappets' acts on one of the sides of a deformable horizontal quadrilateral which is secured to the rocker so as to cause it to swing when it is moved. The said part carries two lateral tappets on the side which corresponds to the horizontal' quadrilateral, for the purpose of deforming it, whilst a central stop is intended to limit the angular movement of the rocker in either direction.

The keys of the keyboard are arranged in series of three keys, for instance along the I two sides of intermediate spindles, each spindle controlling the movements, in the two directions, of one of the parts carrying the tappets or stops which control the angular position of an oscilatingeleinent or rocker.

The drum comprises several rows of characters or type and in order. to make itpossible to bring one of the rows to a given level, so as to allow a character or letter ofthe said row to be printed,=the drum is moved in its axial direction on a key being lowered, by means of a system of levers acting on the spindle of the drum.

-The inclination of the spindle carrying the drum, towards the paper for the purpose of printing a given character or type, is controlled by an element which at the end of its movement comes in contact with the part carrying the tappe'ts or stops.

In order to be able to produce simultaneously the inclination of the spindle of the drum and its movement in the direction of its axis,'the type drum is mounted on a spindle which is longitudinally adjust able but cannot turn, in the interior of'the hollow spindle, the angular position of which is controlled by the depression of one or another of the keys.

The automatic movement of the carriage in the direction of writing, to a length corresponding to that of the character that has been just printed, is brought about by means of a control part also operated by the part carrying the stops, 011 itsbein'g moved, the said control part producing by its movement the release of the spacing mechanism. The control part comprises one or more detachable elements which canbe removed permanently in order that certain of the parts carrying the tappets or stops, shall not, when moved, come in contact with the said control part; The latter is constituted by a pivoted transverse bar against which rests, at the end of its oscillation, the part carrying the stops, producingby its movement the release of the escapement mechanism.

The paper is carried and drivenby a device mounted on thecarriageand comprising two pairs of cylinders driven simultaneously, between which is arranged a detachable flat element which forms support for the paper at the moment of typing.

A construction according to the invention is illustrated by way of example in the accompanying drawings:

Figure 1 is a perspective View showing the chief elements of the machine in the position of rest.

Figure 6 is a plan of the central mechanism, showing diagrammatically the arrangement of the stops or tappets controlling the angular position of the type drum.

The typewriter, according to this invention is a machine of the type in which a cylindrical drum carrying in relief several rows of interchangeable printing characters or type is controlled by the depression of a. key, for the purpose of producing the typing of the character marked on the said key.

The machine comprises:

1. A key board comprising a certain number of keys 1, suitably arranged in groups.

2. An intermediate mechanism producing the movements of the drum so as to bring the character corresponding to that marked on the depressed key, in contact with the paper.

3. A drum mounted on a spindle which in its normal position is vertical but can be inclined towards the paper in order to produce the impression or striking.

This drum has formed thereon several rows of characters or type which are arranged along the generatrices of the cylindrical drum.

4. A carriage operated by a spring acting so as to produce its automatic movement in the direction permitting writing, the said carriage being temporarily held in place, in order to allow a character to be typed, by an escapement mechanism which is released immediately after the typing. This carriage may be brought back by hand, this movement producing the setting of the said spring.

5. A paper holder which carries and drives the paper and may be operated by hand or by the automatic line-spacing mechanism.

The mechanism which controls the movements of the drum must perform the following operations;

1-. To produce the rotation of the drum to a given angle so as to bring to the level of the paper that generatrix of the drum, on which is situated the type to be printed.

2. To raise or lower the drum in its axial direction so as to bring one of the rows of type to a given level.

8. To incline the drum towards the paper so as to bring the type in question in contact with the sheet and ensure the striking.

Figures 1 and 2 show the working of the various essential parts of the machine when one of the keys is depressed.

The key 1, mounted on a crank 2 parallel to the front of the machine, pivots about a supporting spindle 25 provided with a finger 3 which turns an intermediate spindle 4 by acting on a tappet 5.

This intermediate spindle 4 acts by means of an arm 6 on a horizontal bar 7 so as to move it in a given direction. In Figures 1 and 2, the movement is such that on depressing a key 1 arranged on the right of the intermediate spindle 4, the bar 7 is moved to the left.

The bar 7 forms one side of a deformable quadrilateral 7, 8, 9 pivoted at the apices 26 and parallel to the front of themachine. The vertical arms 8 of the said quadrilateral pivot about fixed spindles 10 and are brought back to their original position by means of springs 11 when the key 1 rises.

The fourth side of the quadrilateral is constituted by the horizontal element 9 which may be considered as the main element of the machine. This element carries three stops projecting upwards, namely two lateral tappets 12 and 13 and a central tappet 14.

The first function of the element 9 carrying the tappets, is to turn the cylindrical drum 24 mounted on a vertical spindle 23 and carrying the characters, so as to bring the generatrix of the cylinder, along which is situated the character to be printed, opposite the paper.

To that end, the spindle 23 carries a pinion 22 which meshes with a toothed quadrant 21. The said quadrant is mounted on avertical spindle 20 to the upper end of which is keyed an oscillating element or rocker 18 are parallel to the front of the machine, and which oscillates to the right and to the left, thus controlling the angular movements or turning of the drum 24. In the drawings, the arms of the rocker 18 are symmetrical relatively to its axis of rotation.

The oscillation of the rocker 18 is produced by the movement towards the left or right of an element 15 which is secured to the rocker by means of a pivot pin 19.

The element 15 forms one of the sides of the deformable horizontal frame 15-16-17 supported by fixed pivot pins 27 and 28, the arms 17 of which are connected to the lateral iii] moment the side 16 of the horizontal frame 1516-17 and drive the said side to the left, thus deforming'the frame. This deformation produces an oscillation of the rocker 18, and consequently a turning of the toothed quadrant 21, until the rocker 18 comes in contact with the stop 14, which limits the movement to the left of the part 9, and consequently the locking of the rocker 18 and the toothed quadrant 21 in a given position. The drum 24, the rotation of which is controlled-by the quadrant 21, then represents opposite the paper, the generatriX on which is situated the character which is desired to type.

The second function of the element 9 carrying the tappets is to incline the spindle 23 carrying the drum 24 towards the paper in order to bring about the typing of the character.

To that end, the part 9is provided at each end with a projection 31 which strikes an element 32 arranged transversely of the ver tical quadrilateral 78--9. The said element is supported by levers 33 whichare keyed to a rocking spindle 34. On the same spindle. is also mounted an arm 35 which, when the spindle 34 turns, raises a rod 36 (which turns about'its support37. The said rod controls by means of levers 38 and 39 the oscillation of a rigid frame 40 supported by spindles 41 resting in bearings 42. The said frame is in the tangent plane common to the toothed quadrant 21 and to the pinion 22, and it is secured to the spindle 23 on which is mounted the drum 24, by means of collars The inclination of the frame 40' brings the drum 24 towards the paper and produces therefore the striking of the character.

It must be pointed out that the shape of the teeth of the quadrant 21 and pinion 22 is such that they remain in mesh during th inclination of the spindle 23. i

' The said spindle is locked, and its position is ultimately corrected at the moment of typing by means of a toothed wheel .44 which it carries, andthe teeth of which correspond to the columns of characters marked along the generatrices' of the drum 24, one of the said teeth engaging with a fixed finger carried by the frame or bed of the machine.

Before describing the mechanism moving thedrum 24in its axial direction in order to bring to the desired level the row containtheir tappets or stops 1214 and 15. length of the parts 9 increases from the ing the character to be typed, it is necessary to examine the arrangement and construction of the keys of the keyboard.

Iii-the construction shown in the drawings, the keys of the keyboard comprise three different categories, namely those corresponding to small letters, to capitals and to signs.

The drum carrying the characters, coinprises three lines, the upper line 24 corresponding to the small letters which are cut on its periphery, the middle line 24 to the capitals, and the lower line 24 to the signs.

The keys are distributed in groups of three, each group being echeloned at one side, either on the right or onthe left of an lntermedlate spindle 4 controlling the movements of a deformable vertical quadri-' lateral 789 for the purposeof bringing the stops or tappets 121314 carried by the said quadrilateral, into a given position to which corresponds a given angular move ment or turning of the drum 24. I

The intermediate spindle 4 is turned to the left to a certain angle under the action of one of the three keys arranged on its right, and to the right, to the same angle under the action of one of the keys arranged on its left, provided that a symmetrical rocker 18 is used, as illustrated. This angle is dilferentin the event of the shape of the rocker 18 being unsymmetrical.

The movements to the left or to the right of a vertical quadrilateral 78-9 are therefore controlled by two series of three keys by means of a spindle 4.

In the construction illustrated are shown. fifteen adjacent vertical quadrilaterals, fourteen of which have two lateral tappets 12 and 13 and one central stop or tappet 14, these fourteen quadrilaterals being controlled by a keyboard of 14 X 6 z 84 keys.

The fifteenth quadrilateral 46 which is the one next to the rocker, carries only one central stop or tappet 14, and its movement which may be to the right or to the left,

' produces only the movement of the said tapprevents an accidental rotation of the rocker i in one direction, and simultaneously a suitable stop mechanism (not shown in the drawing) may be controlled by the said quadrilateral when it is moved, for the purpose of preventing the rotation of the rocker in the other direction.

Figure 6 shows diagrammatically the whole of the fifteen elements 9 arranged side by side, as well as the relative position of The rocker 18 towards the keyboard, in order to ensure that each part 9, at the end of its travel, turns the transverse element 32 which controls the inclination of the drum 24, and also turns the element 111 which controls the escapement of the carriage, to

one and the same angle.

The same results may be obtained with parts 9 of one and the same length, by arranging the transverse element 32 and the element 111 at an obtuse angle to the intermediate spindle 4, instead of parallel.

The arrangement of the stops or tappets 12-13 on the parts 9 is such that to each final position of a given quadrilateral corresponds one position of the rocker 18 and therefore a given position of the drum 24 which turns from 0 to approximately 180 in one direction, and from 0 to approximately 180 in the other direction, so that it'is possible to bring to the level of the paper a portion of the rim formed by the characters and is shown clearly in Figure 6.

The central stops 14 are arranged in one straight line at right angles to the front of the machine, whilst the stops 12 and 13 are arranged in two lines symmetrical relatively to the central stops 14 and having the shape of a regular curve, the lateral stops 12 and 13 of the vertical quadrilateral adjoining the rocker 18 being the most widely spaced and those of the quadrilateral next to the keyboard, being arranged the most closely together. Owing to this arrangement of the stops it is possible to obtain a rotation of the drum which increases progressively from 0 to approximately 180 in one direction, according as the deformable vertical quadrilaterals are successively moved in the corresponding direction, beginning with that which is next to the rocker 18, in order to finish with that which is next to the keyboard. The same applies to the rotation of the drum 24 in the other direction.

The mechanism for moving the drum in its axial direction is more particularly shown in Figures 35.

The three keys 1, 1 and 1 form a group arranged along one side of one of the inter mediate spindles 4, and are mounted by means of arms 2 on spindles 25, 25 and 25 concentric with, and independent of, each other. Each spindle carries a finger 3 which acts on a corresponding tappet 5 so as to turn, as already described, the intermediate spindle 4, to a given angle which is the same for each group of three keys.

The spindles 25 and 25 which carrv respectively a key 1 for the capital and 1 for the sign, have moreover towards their end, a projection or finger 50 or 51 of suitable shape which acts on a tappet 52 when the keys 1 or 1 are depressed, so as to depress a bar 53.

The said bar 53, the length of which is approximately equal to that of the keyboard, has similar tappets at the level of the ends of the various spindles 25 carrying the keys, nevertheless, as shown in Figure 3, two groups of keys may act on one and the same tappet.

The shape and the arrangement of the fingers 50 and 51 is such that the depression of the bar may be produced by the action of a key without affecting the others.

Moreover, the fingers 50 which correspond to the capitals, come in contact with their corresponding tappets 52 only after the depression of the key to an extent corresponding approximately to half its travel, whilst the finger 51 which correspond to the signs, constantly press against their tappets and lower the bar 53 to a length twice as great as the fingers 50.

The bar 53 is supported at its ends by rods 54 pivoted about a spindle 55 to which is keyed an arm 56 which controls the rotation of a bell-crank lever or cam 57 of suitable shape pivoted about the spindle 49. Against the said cam 57, the bent end of the spindle 58 to which is keyed the drum 24 constantly presses. The said spindle 58 slides, without being able to turn, in the supporting hollow spindle 23 already referred to, so that the spindle 58 and the drum 24 are able to move in their axial direction relatively to the hollow spindle under the action of the cam 57. The said cam is moved upwardly (Figure 4) by the lowering of the bar 53, so as to bring the drum to the desired height or level for allowing the typing of the capitals and of the signs. It is obvious that the shape of the cam is such that it allows the spindle 23 to be inclined about its support 42.

The carriage 60 which rests by means of rollers 61 on the frame or bed 62 of the machine, carries and drives the paper be tween two pairs of rollers 6364 and 65 66 to which an identical circumferential speed is given by means of toothed wheels 67-68 and the driving wheels 69 operated by hand or by the line-spacing mechanism 70.

Between the pairs of rollers is arranged a fiat element 71 on which takes place the striking of the character or type and which forms an abutment for the paper at the moment of typing. The said element 71 is secured to the carriage 60 by means of screws 72.

The mechanism controlling the move ments of the carriage, and the details of the escapement mechanism form the subject of two separate applications filed concurrently with this application, the said devices are therefore only described in as far as required. for the purpose of completing the general description of the type writer and for facilitating the understanding. of its working.

The automatic movementof the carriage 1n the direction permitting the typing, is

brought about by the tension of a helical mounted on a spindle 102, owing to which the helical spring 101 is set at the same acting by hand on a handle 108 arranged time.

According to this invention, the movement of the carriage to the length correspending to that of the character, in the direction allowing typing, is produced by close to the keyboard, the said handle driving, when it is inclined, a rod 109 controlling the disengagement of the escapement, in such a manner, that in the same way as is the case in ordinary typewriters, if the handle 108 is turned outwards, the disengagement is prepared. and it is only when the handle is straightened, that the movement of the carriagetakes place.

This action maybe produced automatically by the depression of a key, bv key ing to the rod 109 an arm 110 which carries a horizontal rod 111 arranged so that it is inclined outwards, by causing the said rod-109 to turn under the thrust of the deformable vertical quadrilateral which corresponds to the depressed key.

I To that end, the ends of the parts 9 carrying thetappets 12 43-14, are bent along 31, and the rod 111 is at a slightly greater distance from the ends 31, than the transverse element 32 above referred to. In that way, it will be first the element 32 that contacts with the end 31 and begins to incline,

' and it is only afterwards that the rod 111 is driven in order to prepare the disengagement of the escapement mechanism. The quadrilateral returns then to its original posit-ion, and the automatic movement of the carriage takes place in the direction of the writing.

Certain keys, and more particularly those used torwriting signs or mathematical expressions, must merely do the typing, without producing any movement of the carriage. To that end, the rod 111 is made in two parts screwed together, owing to which the length of the rod can be reduced at will in order permanently to placeit outside the field of action of certain quadrilaterals corresponding to the dead keys.

Belowthe transverse element 32 may also be placed a second element acting like the rod 111, and into the said element are screwed stops or tappets the number of which corresponds to that of the vertical quadrilaterals. In order to cancel the action of some of these quadrilaterals on the escapement mechanism, it is sufficient to remove or to unscrew the corresponding tappets.

It may be seen from the foregoing description and explanation that all the parts of the central mechanism have always a free field of action. Their trajectories do not in-- tersect each other at any point, and in order to bring into action one of the quadrilaterals, it is never necessaryto wait until that previously operated, has returned to its original position.

The return movement of the type drum towards its neutral position (Fig. 6) during the typing, is thus eliminated.

The working of the apparatus is as follows:

Let it be assumed that a smallletter is to be typed. A key similar to that marked 1 in Figure 5 is depressed.

The depression of the said key produces the rotation of the intermediate spindle 4 driving the side 7 of the vertical quadrilateral 7-89. In that way, the tappets 12'13 and 14 are brought into a given position, driving during their movement the side 16 of the horizontal frame 161718. This movement produces an oscillation of the rocker 18, and it is stopped at the moment when the said rocker comes in contact with the central stop 14:. The movement of the rocker has produced a rotation of the drum 24 and brought opposite the paper the generatrix of the drum, on which is marked the character to be printed. p

Towardsthe end of its travel, the tappet 31 of the part 9 has come in contact first with the transverse element 32 which produces the inclination of the spindle of the drum towards the paper, and'afterwards withthe rod 111 which controls the escapement mechanism, by pivoting respectively with the spindles 34 and 109.

As soon as the typing of the character is done, the key is automatically raised by the tension of a suitable spring, the frame returns to its original position under the action of the springs 11, and the drum returns to its first vertical position.

The carriage is moved to a length corresponding to a space and the machine is ready for typing a new character.

When it is desired to type a capital inscribed on one of the keys marked 1 in Figure 5, in addition to the operations and movements produced as already described the drum must be automatically moved in the desired level the row of characters in which is to be found the capital to be typed.

In descending, the key acts simultaneously with its finger 3 on the spindle 4-, and with its finger 51 on the element 53 which controls by its descent the cam 57 which raises the drum 24- to the desired level.

The same applies to the key 1 which corresponds to a sign, the movement of the drum in the vertical direction being then twice as great.

The typewriter according to the invention is more particularly adapted for writing languages which have an alphabet comprising a large number f characters as it is the case with oriental languages.

This advantage is chiefly due to the arrangement of the vertical deformable quadrilaterals, the number of which can be very great and on each of which act two series of keys which move it to the right or to the left, each series comprising a key corresponding to a character of a distinct group, and each group constituting a row of the type drum. It must be pointed out that the typewriter shown in the drawings is merely an example for rendering the invention clearer.

Various modifications may be made in the various mechanisms used in the working,

without departing from the invention.
