To all whom 6t may concern:

Be it known that l, Nrns H. Anonnson, a citizen of the United States, residing at lvliddletown, in the county of Middlesex and State of Jonnecticut, have invented certain new and useful Improvements in Typefl riting Machines of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to typewriting inachines, and with regard to certain more dominant features thereof, to type actions and associated and co-acting parts thereof.

One of the objects of the present invention is to provide a type action of simple and practical construction which will be durable and efficient in action. Another object is to provide a type action of the'above character having a desirable touch and capable of being operated at high speed. Another object is to provide a type action of the above first mentioned character which will be comparatively noiseless in operation. A further object is to provide practical means for mounting and connecting the various parts so as to enhance their case of movement and reduce wear. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of the various possible embodiments of this invention,

Figure 1, 2 and 3 are elevational views of a type action and co-acting parts suiiicient in detail to understand the application of the present invention, in normal, intermediate, and printing positions, respectively;

Fig. 4: is a plan view showing a plurality of type actions in their radially disposed relation to the printing point;

Figs. 5, 6 and 7 are detail views showing the manner of connecting the type barto the actuating mechanism.

Fig. 8 is a detail perspective View of a pivot member, and

Fig. 9 is a-detail perspective view of a part of the type action.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now in detail to the accompanying drawings, and more particularly to Fig. l, a cylindrical platen roller 1, here shown diagrammatically in section, is provided with a fiat metallic platen 2. The platen roller is mounted in any suitable form of vertically shiftable carriage, not herein shown, movable in the well-known manner from right to left, under the action of an escapement mechanism 3 operated at each actuation of the machine. Each heylever 4. is connected with a type carrier 5 mounted to slide back and forth relatively to the platen by means of suitable pressure multiplying and speed controlling elements as will now be described in detail.

The type carrier is provided at its rear end with three type 6 for printing difierent case characters when co-acting with the fiat platen 2 as the carrier slides rearwardly between a base-plate 7 and a top plate 8 in the upper rear part of the machine. The carrier is held and guided in its movement by upwardly and downwardly projectin pins 10 and 11, mounted in the bottom an top plates respectively. To the central part and at either side of the type carrier is connected a pair of substantially flat sheet metal links 12 of more or less resilient material which are adapted to be snapped over a central pivot member 13, as clearly shown in Fig. 8. The pivotal connection between the type action and the type carrier comprises what might be termed a ball and socket connection, that is, the type carrier is provided with a central opening having a single flattened side within which is placed the spherical pivotal member 13, having a notch 9 cut in one side to engage the flattened side of the opening in the type carrier, thus to prevent lateral removal thereof when assembled. The ivotal member is also provided'with a stu at each side thereof adapted to engage openings in the ends of the duplex links 12 which are sprung into position thereover in the manner shown in Figs. 5 and 6. This form of connection permits a slight amount of angular movement between the parts of the type action and more specifically between the connecting links 12 and the type carrier itself, as well as providing a more simple form of connection permitting greater ease and a less expense in assembling and changing arts.

T e links 12 are connected at their central portion by means of a stud 14 to prevent spreading and are also provided with a p votal connection at their opposite ends with a pairiof links 15, the opposite ends of which are in turn pivotally mounted upon an L-shaped bracket 16 mounted on a front.

plate 17 of the frame of the machine.

This bracket is capable of adjustment in a fore and aft direction by means of a setscrew '18 engaging a tapped-out recess in the front wall and is held in adjustment by means of a verticall disposed clamp screw 20 engaging a simi arly intermediate adjacent actions, as clearly shown in Fig. 4. By loosening the clamp screw 20 between any two adjacent actions, the adjusting screw 18 of' either action may be turned in one direction or the other to vary the limit of throw of the type carrier, I

thus regulating the pressure with which the type co-acts with the paper carried by the platen. As the links connecting the bracket and the type carrier form a toggle which assumes extended position, as shown in Fig. 3, when the. type action is actuated, the

limit of hrow of any type carrier can thus be positively adjusted and the pressure of all thetype actions made uniform, thus producing a typewritten page which will be conspicuous for its absence of extremely. heavy or light printed characters.

7 The link 15 is composed of two parts, one

upon each side of the bracket, and each part is provided with an off-set portion 21 to which is pivotally connected the rearward arm 22 of a momentum acquiring means, preferably a momentum accumulator weight 23, which arm in turn, is pivotally connected near its middle to the up-,

per arm 24 of a sub-lever, preferably a bell-crank lever. This bell-crank lever is composed of two parts mounted on either side of the bracket 16 and pivoted at 25 on the lower part thereof as shown clearly in Fi 9.

This bell-crank lever is provided with two arms 26 and 27 extending forward and rearward, respectively, from the pivot 25. The forward arm 26 is adapted to co-act with a pad 29 of felt or other suitable semiresilient material mounted upon a support 28 in the front wall 17 of the machine when the type action is moved to printing position. The rear arm 27, which is the longer tapped-out recess of the two, is provided with an upper convex surface and is adapted to coact with a second sub-lever 3O pivotally mounted at its wire 32, upon which the sub-lever 30 is mounted, is common to all of the type actions. As herein shown, wire 32, upon which the open forked end 31 of the lever 30' -is mounted, is reduced or flattened on one side. This form of construction facilitates the assembling or removal of the lever, for it will be clear from the drawings that by swinging the lever 30 downwardly into a vertical position, after removing the action and disconnecting the pull wire, the reduced or flattened portion of the wire 32 will then occupy a relative position parallel to one of the straight sides of the open end, thus permitting the lever 30 to drop away therefrom.

Near'the forward end of the lever 30 is pivotally connected a pull wire 33 provided with a s'uitable adjustable connecting means or clip 34, the lower end of which is connected with the body portion of the keylever 4. I

It will thus be seen that as the key-lever 4 is depressed, or moved on its printing actuation stroke, the lever 30 and rear arm 27 of the bell crank sub-lever will have'a rocking or heel and toe action, the points of contact or power transmitting portions, of the su -levers progressively approaching the fulcrum of the bell crank lever.

initial engagement between these parts when the action is in normal position provides a relatively large leverage for the bell crank lever, which moves the type carrier toward theprinting position, thus producing an easy and desirable initial touch. However, as the key-lever continues its downward movement under-the touch of the operator, the point of contact between the lever 30 and the bell crank lever arm 27 moves toward the pivot point 25, thus reducing the leverage on the bell crank lever, but increasing its rate of movement, thereby materially increasing the manifolding properties of the action as a whole.

In order to further increase the pleasantness of touch in an action of this character,

the key-lever is composed of two parts, one

by a pad 38 of felt or other semi-resilient 54 from the frame of the machine.

- but straddling the universal bar.

material positioned to receive and arrest the forward end 40 of the member 35, The upward movement of the key-lever is limited by a similar pad 41 mounted at the top of a comb member 42 adaptedto guide the key-lever 4 in its up and down movement. It will thus be seen that as the key-lever 4 is depressed, the body portion 35 co-acts with the stop 38 and its movement i arrest ed. The key itself, however, being mounted upon the part 4 of relatively lighter material presents a certain resiliency to the finger of the operator which renders the rapidly repeated operations less tiresome.

A return spring 43 is adjustably connected to a downwardly projecting lug 44 on the under side of the key-lever. The other key-levers (not shown) are provided with similar springs, all of which are connected to a single yoke 45 which in turn is connected by means of a link 46 to a fixed portion 47 of the front part of the frame. By turning a holding nut 48 on the forward end of the connecting link 46 the tension of all the key-levers may be simultaneously regulated. 1

As these several features regarding the key-lever construction and adjustment form no part of the present invention specifically, except in so far as certain features co-act with the type action as a whole, it is thought to be. unnecessary to describe the same more in detail, as they will form the subject-matter of one or more separate applications.

Instead of positioning the universal bar beneath the key-levers, as in many forms of front-strike machines, it is in this embodiment positioned in the upper front part of the machine whereby it may be actuated directly'by similar elements in each type action. -As herein shown, the universal bar comprises a frame 50 in the form of an arc and is positioned just below and in rear of the pivot point 25 of each bell crank lever. A fork or yoke 51 is swiveled on the rearwardly extending arm 27 near the point of connection of a return spring 52 of each bellcrank lever and normally rests slightly above The universal bar is pivotally supported by means of a plurality of arms 53 of substantially the same length connected to dependingbraceflzs e lower part of the universal b'ar frame is pivotally supported at the ends of three arms 55 of substantially the same length, only one of which is herein shown, connected respectively with either end and the center of a universal rock shaft 56. The rock shaft is lhe oscapement mechanism 3. The pull wire 58 passes freely through an opening 60 in the transverse beam 47 of the frame of the machine as well as the comb 42 for the key levers. A self-locking adjusting nut 61 is provided at the forward end of the pull wire for adjusting the distance between the fork and universal bar, and another 62 at a point in the rear of the beam, between which second nut 62 and beam 47 is coiled a spiral return spring By means of these adjusting means the relation of the universal bar 56 to the bell crank lever may be regulated as well as the proper timing of the eseapement mechanism and tension of the action as a whole. However, as these fealures form no part of the present invention specifically, except in. so far as they co-act with the type action, a more detailed description of the various features and advantages is believed to be unnecessary.

The operation of the present device is substantially as follows:

Assuming a machine to be in normal position, as shown in Fig. 1, as the key-lever 4 is depressed, or printingly actuated, movement is transmitted to the pull wire 33 connected with the body portion 35 of the keylever to the forward end of the lever 30 which-in turn rocks downwardly upon the upper curved surface of the rear arm 27 of the bell crank-lever. This movement causes the upper end of the bell crank arm 24 to swing rearward on its rinting movement about its pivotal point of support 25, which in turn carries the rear arm 22 of the momentum accumulator rearward and downward. As the movement continues, the toggle formed by the links 15 and 12 moves toward straightened position, as shown in Fig. 2. Likewise the rear arm 22 of the momentum accumulator and the upper or longer arm 24 of the bell crank lever assume a partially extended reverse toggle. As soon partially on the length of its swinging 120 radius, in riarward and downward direction to complete the printing operation by forcing the type carrier to the printing plane, as

shown in Fig. 3, that is, with the type in contact with the paper carried by the platen. 125' It will be noted that at this point the toggles formed by the links 12 and 15 as well as the reverse'toggle formed by the rearwardly extending arm 22 of the momentum accumu-.

lator and the upwardly extending arm 24 of 13a the bell crank lever assume a straightened positions. It will also be noted that in the position shown in Fig. 3, the power transmitting portion of the rear arm 27 of the bell crank lever has moved out of contact with the power transmitting portion of the lever 30 and has placed the spiral return spring 52 under tension; there is therefore nothing to prevent the momentum accumulator from erformin its natural tendency to rebound from stop ance of this return spring, to carry the type immediately out of engagement with the platen regardless of the release of the keyl5 lever. It is during the final movement, that is, while the carrier is moving from the position shownin Fig. 2 to that shown in Flg. 3, or while movement of the type carrier is effected by the energy stored in weight 23,

v that the fork 51 carried by the rear arm 27 of the bell crank lever coacts with the universal bar 50 tourge the same downward.

This downward movement of 'the universal bar will, through its connecting mechanism, rotate the universal rock shaft 56, which in turn, through the pull wire 58, actuates the dog rocker of the escapement mechanism 3.

Owing to its mounting the universal bar will have a slight movement longitudinal of the sub-lever, or arm 27, and the element 51, be-

ing movably connected to said sub-lever will readily follow this longitudinal movement and be retained in pressing position, thus dispensing with substantial friction between the universal bar and this sub-lever during actuation of the escapement.

The escapement mechanism which is preferably of the reverse style, that is, with the fixed dog normally in engagement with the teeth, will complete its operation on the down stroke of the key lever when normally operated, thus permitting the carriage to move a letter space distance from the right to left. The movement of the type from the 45 position shown in Fig. 2 to that shown in Fig. 3, and return, is almost instantaneous and yet being pressure-operated by means of toggles and power multiplying devices interposed between the type carrier and the key lever, its operation is substantially noiseess. Y

WVhen the key-lever is released the parts naturally return to the position shown in" Fig. 1, under the action of the several re- 55 turn springs 43, 52 and 63 which all co-act one with the other to produce the desired result.

A pad 64 is provided on the upper surface of the front wall of the machine having an upwardly and rearwardly inclined upper surface coacting with an inclined surface of the under side of the momentum accumulator weight 23 adapted to cushion its return and prevent a rebound thereof. The 65 center of the weight23 does not move in the ar 29 with the assist-' are of a circle, due to its compound pivotal connections and the path of travel of the final portion of its return movement is in a substantially straight line at a very slight angle to the upper surface of this pad. Re- .0

ferring to Fig. 1, it will be seen that the 'weight is in its most effective forcing POSI- tion than it would be if said angle were acute initially.

It will be noted that the various parts comprising the present embodiment of the invention are so constructed and connected as to cause a minimum amount of wear; the various cushioning and spring devices for arresting the movement of such movable parts produce, in their co-action with the other parts, a machine which is substantially silent in its operation.

It is thus seen that this'invention provides a practical and simple construction which is durable and highly eflicient in action and one that is adapted to accomplish, among others, all of the objects and advantages above set forth.

As many changes could'be made in the above construction and many apparently widely diflerent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
