igure 20 is a detail view of a moditication.

As above stated, the invention is illustrated as embodied in the Royal standard machine and there is shown the main frame A, the usual carriage B carrying a platen C, the usual key board with type operating keys D, the glass panels E in the sides of the frame, the depending universal tension adjusting means G, all of which are found in said machine. Since the invention in no substantial Way modifies the form or operation of these instrumentalities it has been deemed unnecessary to illustrate the same in detail.

The front plate 1 of the machine has glass inspection panels H and this plate, together with the sides 2 of the main frame, support top plates 3 which are fastened thereto by screws or in any other desired manner. A segment 4 having grooves 5 to receive the 4*type carriers is carried by the underside oi these top plates. This segment together With the type guide G (when used) may e substantially the same as that noW used in the standard Royal machine but is, of course, positioned in an entirely different manner, In some forms of the invention, the type guide 6 may be omitted as unnecessary. plurality of type arms or carriers 7 are plvoted in the segment 4 on the usual pivot wire These carriers normally hang by gravity in substantially vertical position and rest against a type rest 9 of suitable material.

Pivoted to each type carrier at a point 10 intermediate its ends as best shown in Figures 1 and 3 is one member 11 of a toggle which is pivoted at 12 to the other member 13 of the toggle which in turn is pivoted at'14 to a plate 15 attached at its central portion to the front plate l between the glass panels H and supported at its ends in any suitable or desired manner. The member 11 of the toggle preferably has an extension 16 beyond the pivot point 12 which gradually contacts with the side of the member 13 when the toggle is straightened and thus prevents any overthrow. The movement of the toggle is also limited by the contact of the member 13 with a sound deadening pad 17 of any desired character. A spring 13 is attached to the toggle member 13 and to an ear on the plate 15 in such manner that it very slightly resists the sraightening movement of the the same when the key lever is released.

The key levers 1S are ofthe usual type and bar F, and the spring,

are pivoted on a transverse rod 19 carried by a bridge 20 which extends from one side of the machine to the other. Each key lever is connected to its appropriate type carrier by means of a link 21 having an adjusting means 22 oi the character shown in mv lat- 'ent No. 1,227,438 granted May 22, 191i', and

illustrated in Figure 19. In this construction one member 21a of the link 21 is adjustably connected with a plug screwed into one end of a tube 66 and held in its adjusted position by a nut 67. The other member 211 of the link 21 enters an internally threaded sleeve 68 and is adjustable therein, being held by a nut 69. The sleeve 68 enters the tube (i6 and is formed at its inner end with a head 70. Between this head and the end oit the tube is a compression spring 7l. This connection is not only adjustable but permits a certain cushion period in the movement oi the key lever.

It is to be understood that any of connection may be employed which will permit a further movement of the key lever after the type carrier has been swung to its operative position in front of the platen and the toggle has been straightened. It is also to be noted that the two portions ot the depression of the key lever may bear any desired relation to each other.

The link 21 which is connected to the key lever is connected at its other end to the member 13 of the toggle above described. le spring 23 attached to each key lever and to an ear on the front frame member l tends to return the parts to normal position. The weight of the type carriers themselves `Will also tend to return the parts to their rest position by gravity as soon as the toggle begins to break.

Mounted between the top plate 3 and ris ing above the same is a guide uember 24 having a removable inspection plate 25 in its upper surface. An impression member or block 26 is mounted to slide in the guide 24 and has pivoted thereto one member 27 of a toggle which is pivoted at 28 to the other member 29 of the toggle. This member 29 is pivoted at its end at 30 to a block 31 carried by a rod 32 which is screw threaded into the iront portion of the guide member 24 as clearly shown in Figures 1 and 10. The position of this block 31, and consequently the etfective Working position of the impression member 26, can be varied by turning' a tinger piece 33 on the front end of the rod 32. This finger piece is provided with an indes: 34 which passes over' a scale 35 as shown in Figure 12. This affords a very simple and efficient means for varying the printing impression and permits adjustment for manifolding in a quick and easy manner.

Connected to the toggle just lescribed at the pivot point 28 is a link 3G, the other end of which may be engaged to any one oi.E a

other form force of the -Y 4neaaeao plurality of holes V37iin an arm 38 .of a bell crank member forming part of a universal frame. or member which is pivoted to turnl `at right angles to the longitudinal axis of the arm, and forms a casing 46 having a transverse seat or opening in which is slidably mounted a type block 44. This block may be mounted in the type carrier in various ways. In the construction shown in Figures G and 7 the free end 43 of the type carrier has a slight depression communicating with a passage in which, is inserted and held one end of a spring which tits into a cut-out in the type block 44. This permits ready assembly ot the parts and the removal of the spring whenever it is desired to replace the same. The casing 4G for the type block is attached to the type carrier by welding, soldering, or other desired manner. This casing may be very thin since vit merely affords a guide for the type block and does not have to resist the torce oft the printing blow as does the usual type bar. It is evident that this construction allows the type block to be moved within the casing toward the platen and that the spring 45 will return it to normal position whenever the pressure is removed therefrom. Thus, the block is movable in a direction parallel to the longitudinal axis of the arm or carrier.

An alternative method of mounting the type blockis shown in Figure 9. In this construction the type block 50 has two forwardly extending arms 51 which are attached to a member 52 and guided' in a web 53 of the type carrier.

A bowed spring 54 is positioned between the web 53 and the member 52 and tends to return the type block to normal position when pressure is removed therefrom.

A further form oi type block and mount.- ing is shown in Figure 14 in' which the end of theimpression member 26 is formed with side portions 72`separated from a central portion 7 3 by spaces slightly wider than the thickness of the walls of the casing 46 in which the typeblock 44 slides. When the impression member is actuated, the part 7 3 engages the type block while the outside walls 7 2 tit outside of the casing 46, th* 1s centering,

and aligning the carrier at the moment of printing. y

A still further modiication is shown in Figure 15 in which the free end of the type carrier has a hollow head '74 provided with a '55 web 75 while the type block is carried by a plurality of pins 7 (l which slide in openings in the web 7 5 and are provided with coiled springs 77 which tend to return theA type block to its normal position. The impression member 26 is provided with two grooves or depressions 78 which are adapted to contact with the rounded or bevelled ends of the pin 7b' and thus-'force the type block to its printing position. @bviously various other forms may be employedor mounting the type block in the free end of the type carrier. In all cases as is clearly shown in the figures and particularly in Figure 16, the face ofthe type will lie normally within the casing so that the type will be protected from damagewhich might be caused by any interference between the type carriers or in any other manner.

The bell crank carried by the universal trame or member above described has an arm 47 which may, if desired, be independent of the arm 38 and connected to the rod 39 to oscillate therewith. This arm is connected by a link 4S to the usual depending universal bar F of the Royal standard machine through which the escapement and ribbon mechanism are actuated. The coil spring 49 surrounds the link 48 and has the usual spring tension adyusting means G connected thereto. In this manner each time a key lever is depressed and the universal frame is rocked, motion is transmitted to the universal bar F andthe escapement, ribbon vibrating and ribbon feeding operation are effected in the usual manner.

It is believed that the above description is suh'icient to show clearly the operation of the type action but it may be briefly described as follows. It a type carrier 7 is in its normal position and the key lever 18 corresponding thereto is operated,'a' pull on thelink 21 will move the toggle constituted by the members 11 and 13 from the dotted line position of Figure 1 to the full line position. This will result in swinging the type carrier 7 to a position in front of the platen, where it is held stationary during the printing movement of the type block. A continued depression of the key lever will operate the universal bar 41 and thereby pull on the link 36, straightening the toggle formed by the members 27 and 29 and forcing the impression member 26 against the type block 44 thereby pressing the same against the platen and producing the desired imprint. The travel ofthe type block can be bodily adjusted forwardly or backwardly to vary the effective working position thereof by varying the position of the block 31 as above described and in this manner provision can be made for manifolding any desired number of copies. At the same time the rocking of the universal bar 41 will rock the frame and the arm 47 and as above described will transmit movement to the escapement and ribbon litiy mechanisms. As soon as pressure on the key lever is released, the springs Q3 and 49 Will start the return of the parts to normal position which Will be hastened by the Weight of the type carrier itself, and the spring associated With the type block will return said block to its initial position Within its casing.

Since the printing movement is brought by pressure and not by impact and since the movement of the two toggles is limited by contact with sound absorbing pads, it will be evident that this type action is substantially noiseless.

Various niodilications in the manner of transmitting motion from the key lever to the type carrier and the printing or impression member may be made Without departing from the spirit of the invention. One of such modilications is disclosed in Figures 1() and 11. 1

In this construction the key levers 18 are connected by links to front links 56 pivotally carried by a member 57 attached to the front frame member 1 at its center and supported at its ends in any desired manner. These front links correspond closely in general structure to. those employed in the present standard Royal machine. These links 56 are connected by links 58 to points 59 of the heels of the type carriers 7 In all other respects the type action itself is identical with that described above. The links 58 will of course be yieldable. The operation thereof is believed to be evident.

There is also disclosed in this modification a. further improvement which may be embodied in the first form shown i desired. The member 61 which is pivoted at 62 to a i bar suitably supported by the frame of the machine is connected by a link to the arm 38 of the universal frame. This member 61 has an upward extension G3 adjustably connected thereto and the upper end 64 of this -extension is of such form that it will fit under and support the free end ot the type carrier 7 Which has been swung to printing position. It is to 4be noted that this member 61 does not beginv its movement until the universal frame or member is moved and that this universal frame does not begin to move until the type carrier 7 has been swung into position in front of the platen. As the toggle formed by the members 27 and 29 begins to straighten, the member 61 simultaneously swings forward and its end engages under and behind the type carrying end of the type carrier or type bar 7 thus opposing any displacingmovement that might accidentally be given to the type carrier at the time of printing. .Each type carrier is in ell'ect locked in its printing position While the type block is being projected to form its imprint upon the platen.

There is shown in Figure 18 a modilied form of type carrier in which the body portion 7 may be round and the free end 7 9 is slightly enlarged and formed with an opening in which is inserted a tapered portion formed on the casing 46 vwhich encloses the type block 44. This permits the casing carrying the block to be attached to the body of the carrier in any desired angular position.

The side panels E which lie toward the front of the machine may be provided with hinges 81 and a catch 82 which will allow these to be opened for the purpose of cleaning the type faces which lie facing downwardly when the type carriers are in normal position. The housings for the ribbon spools K may be made integral with the top plates 3 but the tops of the spools lie somewhat above these top plates as shown in Figure 17. The ribbon will be led from one spool to the usual vibrator as indicated in this ligure.

It will be noted from Figure 17 that when there is no type carrier in operative position, the entire printing line is visible and erasures may be readily made at any point without the necessity of rotating the platen.

There are certain features of construction to which it is desired to call particular attention. All of the type carriers are vertically and radially arranged and When swung they bring the carriers and the type blocks carried thereby to a definite predetermined distance in front of the platen and preferably closely adjacent thereto, and at the same time quite closely adjacent the impression member. The carrier and type block are very light and the touch is correspondingly light. When a connecting link is employed which has a spring therein, this need only be strong enough so that the type carrier will be moved to position in front of the platen by the first part of the de ression of the key lever, and in View of the light Weight of the carrier, only alight spring will be required which will add but little to the work to be performed by the depression of the key.

The actual printing is performed by the movement of the impression member, and this movement, as well as the actuation of the escapement and ribbon mechanism, is brought about by the latter part of the movement of the key lever when it has acquired a certain momentum. Moreover the type block will be brought to its predetermined position in front of the platen with a minimum stress on the toggle or other connections, thus obviating any danger of vibration in bringing the type blocks to a correctly alined position. All of this movement takes place in advance of the increased load` which results from the movement of the block to print, the operation of the escapement, ribbon mechanism, etc.

All type blocks move in a longitudinal plane and the necessary movement to printing position is very slight. The end of the impression carrier enters the casing only a very slight distance, and since the carrier swings downwardly-and away from this impression member, there is no interference between the two. It is'clearly possible for a second type carrier to be moved up into position before the toggle has returned to its normal position, and this tends to permit great speed in operation.

The segment shown will permit a wider spacing of the type carriers if for any reason found necessary or desirable. In all such respects the drawings are to be considered as rather illustrative than limiting.

It isto be noted that the machine is entirely dust-protected from every point of view. Particularly do the top-plates serve to protect the pivots of the key-levers, type carriers, togglemembers, and other oints of pivotal connection in the action. oreover, the type blocks when at rest, face downwardly and are positioned toward the front of the machine so that any erasures from the paper on the platen cannot fall on the type or any ot the pivotal connections above mentioned.

It it is found desirable to obtain a more accurate alignment especially for the type carriers located at the sides of the segment, each type carrier may be provided with a Aprojection 83 which will engage the inner face of the type guide 6 when the carrier is moved into its operative position. This construction is illustrated in Figure 20 and is merely for the purpose of obtaining additional accuracy in alignment if at any time it should be -found desirable.

It is evident that various features of the invention may be widely varied in their speciic embodiment. Different forms of coiinection between the vtype carriers and the key levers can be employed, and details changed as is found necessary or desirable' to adapt the action to machines of varying forms. In general it is to be understood that the invention is to be regarded as limited only by the scope'ot the appended claims.
