To all Whom it may concern Be it known that I, GEORGE Vonminn, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented cer men and useful Improvements in 'lyiar Writing Machines, of which the following is a specification.

pression by the depression of a key or key lever.

Where, as is now usual in machines of this class, lines or rows of dots, dashes, or other characters can only be made by successively depressing and releasing the key or liey lever for each character in the row, an unnecessary amount of time and energy is wasted, and the usefulness of the machine is elfectually limited because of the danger of confusion if the lines are omitted, and the waste oi time if the lines of'clots or dashes have to he made by repeatedly and succes sively depressing the key. This is particularly the case in the billing of goods, where the items are arranged in columns at the extreme left of the sheet and the charges at the extreme right of the sheet. If the intervening space is left blank the reader, in endearoring to select a particular item and its cost, often resorts to a ruler to guide the eye, while the use of a line of dots or (lashes to connect the item and its cost is forbidden on account of the consumption of time and energy.

lt is the object of the present invention to provide improved means for writing lines consisting entirely or in part of a suceession of dots,.dashes or other characters, in rapid succession, by simply holding depressed one or more key levers and prefer ably by causing this to he done automati cally in the ordinary power driven travel of the carriage to the left, or, in other words. to cause the characters to be written from left to right as in ordinary Writing.

A further object of the invention is to pro ide means for instantly changing the activities of thernachine from writing ordinary matter to automatically running off a line, or part of it line, of dots, dashes, or

other characters, and then at any esii i point, instantly resuming the of matter in the ordinary way.

A further object is to pro ide means whereby the lines of dots or dashes can made with sufficient power to make a suit able impression upon the waxed other plates to be used for stencl' More in the atures of construction. combine tion and arrangement of parts hereinafter described and claimed.

In the drawings 1 have shown the in; vention applied to an L. C. Smith & Bro. typewriting machine, hut it is to be undon stood that the invention may he embodied in other styles of machines.

The carriage and rack are connected with the usual power drum 83 and its actuating spring 84, by means of a strap 85 sedurcd at one end upon the periphery of the drum and at the other end to the end of the carriage which is farthest away from the drum. G represents the printing ribhon, and F the guide plate therefor. The guide plate is connected with a reciprocating means, as shown in Fig. 23, consisting of the levers H, I, J, K, the linlLLJmd the bell crank N, through the medium of whichiit is operated. The guide plate F serves as a Ilbbon carrier and reoiprocates' in an approximately vertical .plane in front of theplaten B, carrying with it the ribbon G. The usual type-bars of the machine, as well as the vibrat-cry type-bar X of my invention, are arranged forwardly of the platen, which they strike from in front centrally of the guide plate. 0 represents one of the usual type bars and a, a a, a a are pivotal hearings in the frame A. P, is the escapement wheel and Q the escapement shaft. R represents the tabulator bar or key which, when depressed, releases the carriage by means of mechanism hereinafter described.

Smith. & Bro. typewriting machine, and need not be more particularly described, except so far as a more detailed description may be necessary to understand the relation of my invention thereto.

Referring to the drawings, the invention comprises several coiiperating groups of mechanism, amongwhich are the swinging pawldriving: mechanism V, the rocking arm, gripping and controlling device W,

' the linked type bar X, and the operating key Y. These are arranged in such 006perative relation to themachine as to cause the printing instrumentalities to strike the platen in front. 'rQ a tcomplish this the power to actuate the type bar is taken from a point behind the platen and carriage, transmitted around the necessary angles and underneath the carriagdflg ggpoint in front of the platen In carrying tthe invention I take the power from the spring drum indirectly through t carriage and escapement shaft, as will be hereinafter explained, instead of from the spring drum direct.

Referring now to Figs. 5, 17, 18, and i9,

theripawi urivin'g'mechanism V comprises a toothed device or notched wheel 2 mounted rigidly on escapement shaft Q, and a supporting brdckct 4 having a base 5 fastened to the frame, a journal box 6 at ts top, and

a stop pin 7 intermediate of its height. Carried by the bracket is a drop hanger 8 havmg parallel uppernnd lower journal shafts I 9 and 10, respectively, the journal shaft-2,9

having hearings in the journal box 6, 'nd 76 the lower shaft 10 having its bearing in ,the pawl 15 hereinafter described. The ournal shaft 10 terminates in a screw threaded. portion fitted with stop and lock nuts212.

and 13, respectively. Rotatable upon the shaft, and provided with a stop pin 14 above and parallel with said shaft, is a pawl lever 15,-which has spring connection 17 with the pawl lever. The spring tends to draw the legs 18 toward each other, and thus nor mally keeps the acting end of the pawl in a downward position, as shown in Figs. 17 and 19, in the path of the notched wheel 2.

shown in Figs. o, 21, and 22, the trans-f mission rod 19 has at one end a block 20' pivotally mounted on the shaft 10 and slidable longitudinally between the guides 21 of the head 22 of the rod. This block can a be adjusted longitudinally by means of an adjustment screw 24 threaded through the end wall of the head 22 and having swivel 10C connection 23 with the block.

The group of mechanism which I have called the rocker arm, gripping'and controlling device lV, as best shown in Figs. 5

and 12, comprises a stand 25 having a base portion 26 fastened to the frame A, a studded top 27 and an offset intermediate lug"- 28 carrying rigidly a rearwardly extending pin29. The stud 30, which is fast to the top 2? forms a journal shaft for the roehi g arm 31 journaled. upon it by means of the bearing32 which is-arranged at the juncture of the radial arms 33 and 34. 'l'husthese arms form a bell crank. The

arm 33 terminates in a gripping device consistmg of an open V-shaped jaw 35 within which works a laterally moving spring controlled latch 36. This latch and its controlling spring are incased in a sectoral slidmg member 31 which slides within a guide 38 arranged on the underside of the rocking arm 31, and preferably integral therewith. The arm 34 has at its outer end an upwardly extending finger 39 which is connected by means of the spring 50 with a lea ver arm 49, hereinafter mentioned, and is formed intermediate of its length with a hole 40, within which is rotatably received the downturned journal pin 41 of the transmission rod 19.

I mew... Mr.

In Fig. 2 of the drawings the parts are shown in their normal position when out of use, while in Fig. 1 they are shown in the position assumed by them when the key lever J is depressed by the operator. As will be there seen, a hen the plate 68 is depressed against the pressure of its spring the controlling lever 64- will be turned so as to actuate the forked bell crank 52 through the medium of the rod 62, bell crank 59, and rod 57. When the bell crank is thus turned, its forked end 54- will push the latch 36 and its casing 37 in the direction of the iaw 35 and thereby blOCh the entrance to the 5111116, as shown in Figs. 7 and 16, leaving an opening 81, however, to receive the journal end 78 of the link 74-. At the same time the bell crank 52 also actuates the spring lever 49 by means of its projecting cam lug 53, which engages the nose 51 of the spring lever. In this movement the latch 36, the rocking arm 31, and the spring .30 will have changed from the position shown in Fig. 15 to that shown in Fig. 16. This is accomplished by the depression of the plate 68 before the depression of the key lever J has begun. The rotation of the rocking arm 31 about the stud 30 effected by the movement of the spring lever 41) in that itshifts the line of force in the spring 50 from one.

side to the other over the stud 30, or in other words dead center. The segmental guide 55, bung concentric with the stud 30, will move between the tines of the forked end 54.. and thus permit lateral movement of the latch and its casing while the rocking arm 31 is in motion.

Another movement etlected by the depression of the plate (38, through the medium of the rocking arm 31, the forward and upward movement of the transmission rod 19 owing to its pivotal connection 40 with the rocking arm. When thus moved, the transmission rod will communicate its motion to the drop hanger 8. and cause the hanger to s ing forward and rotate about its upper journal bearing 9. carrying with it the pawl 11' which is pivotally mounted on the lower journal. shaft 10, until the hanger bar engages. and is stopped by, the pin 7. During this movement the pawl is held with its stop pin 14 pressed against the hanger, by means of the spring 1?. This upward and forward movement, it will be seen, has changed the position of the pawl 15 from its normal position shown in Fig. 5, wherein it is drawn out of range of the toothed wheel 2. to that shown in Fig. 19, wherein it is forced forward into the path of the toothed wheel as thelw heel turns in the direction of the arrow. The functions then of the controllin lever 64 may be summarized follows: .irst: Its depression by the operator changes the position of the parts from that shown in Figs. 4 and 15 to that shown in Figs. 1, '3", 14c, 16, .18, and 19. In other words it throws the machine into gear, with the pawl 15 in the path of the toothed. wheel :5. and prepares the latch and gripping do ice for the reception of the downturned end 7 'u' the link 74. Secondly: Its release from pressure by the operator permits the spring 70 to expand and turn it back into normal position, thereby restoring the forked bell. crank the latch and its casing to their normal position, but the spring lever 49 will remain. in the position shown in Fig. 14, since the cam lug 53-, upon being restored, simply recedes from the contact nose 5i, and leaves the springlever 49 unmoved. It will be evident, therefore, that the rocking arm 31, transmission rod 19, hanger S, pawl 15, and spring 50, which depend upon the lever 49 for restoration to normal position, will also remain unmoved, and will retain the positions shown in Figs. 1, 13, 1-1, 16, 1'4", 12$, and 19. except that the latch and its casing 37 will have been restored to normal position through the movement of the mental guide 55.

The restoration of the spring lever 49 and the above named parts depending on it occurs follows: It will be remembered that pawl 15 is still in gear, that is in the path of the toothed wheel because the lever +9 still holds the spring 50 to the left of dead center (stud 30). And even if the operator of the machine trips the usual carriage release lever and pulls the carriage to the right to start a new line, thereby reversing the direction of the toothed wheel 2, the above mentioned unrestored parts will still remain unmoved except that the pawl will ride over the teeth of the Wheel 2 against the tension of its spring 17, as shown in Fig. 18. But when the operator begins to write by manipulating the keys, the eseapement shaft and the toothed wheel 2 will now turn in the other direction, namely to the right, as shown in Fig. 19, and will engage and kick back the pawl 15, which is still in range. The impulse thus given the pawl will be transmitted through the rod 19 to the rocking arm 31. thereby turning this arm until the spring 50 passes dead center and draws the lever 49 back to its normal position. When thus restored the lever 49 will. hoid in restored position all of the above named parts depending on it.

The foregoing explanation refers only to the results obtained by the depression of the finger plate 68, it beingassumed that the plate has not been so far depressed as to exert pressure enough to actuate the her lever If, after depressing the plate 8 ii the limit of pivotal movement, the operator continues the pressure so as to depress the 52 and its cam lug 33, and also Hm. typix'vrit ing maihl} the posi hen the type w 1, esition e.

This is accomplished. by turir ing the adjustment s'crev 2 so as to. cause the block 20 to slide between its guides as heretofore explained. At the same time the speed of the car" will be controlled by the force of the w because the harder the type strikes the platen the greater will be its retardin eii'ect thereon. obvious that w ere the work in hand er mits the dots to berun to the end of a me, a higher rate of speed can be used than in work where the operator must stop the cerriage in the middle of s line by releez-sill the tnbulator key. in such case the s 60% of the carriage can he reduced by lengt ening thetransmission bar so as to increase the force of the blow and thereby increase the resistance of the ty e bar to the leftward movement of the p aten. If, now, the transmission rod 19 is shortened sufliciently to prevent the type ends from reaching the platen, the type bar X wili be rendered ineffective to mm, and the only efiect of o crating the ey leeet 5 will be to cause the pawl 15 and theunechsnism. operetively c0nnccted with it to serve as retarding means for retarding the free run of the carriage when the carriage is released from'the control of the escapement mechanism, the pawl acting as a drag upon the toothed Wheel 2 which turns with the pinion E. This is particularly useful in tabulating Work where long runs of the carriage are necessary.

It will .be seen that by the mechanism here shown I use the power dri en travel of the carriage to the leftward, that is in the direction of its feed, to force the type bar X against the platen, so that I get into the blow the power of the cerriage-impelling force, and so that the dots are run automatically at any place in the work by merely holding two keys depressed for the length of time desired, When the keys are released the dots will instantly cease and the Writingof words can be resume The invention, however, is not liimted to eutomatic writing, for, "when the hey Y is do pressed with one hand, the carriage and usual release lever Z can be grasped with the other hand and drawn back and forth at will, whereby a line of (lots or dashes is Written with every trip of the carriage to the left. When manual force is thus used to operate the carriage. the transmission bar 19 can be adjusted to strike a harder blow than would be possible where the power driven travel of the carriage is used, because the force of the (-arriegedriving power is limited, but suiiicient manual force can always be supplied according to the needs. This capability of causing very hard blows to be struck when the carriage is operated by hand is especially useful in making stencils where the type must be driven into the waxed sheet or stencil plate.

It will be seen that the type ends 76 and 77 are separated by a distance corresponding to the distance between the capitals and small letters of the usual type her. To use It will be into operating" position. 1:
