This drive takes place through the. medium of (ltEttiCllltlJlO clutches, so that only that operative member is driven by the working shaft whose clutch is engaged. The cam is also fast on the working shaft. As soon as this cam has rotated so for that its projection 25 reaches a slide 26, the lattcr is moved downwzird against the action of a spring. not shown, acting in the directiin of the arrow and by mennsof its pin 27 removes the locking lever 1.7 from the ratchet 5 ofthe controlling shaft before the 1 shaft 24 has rotated one complete revolu tion. The projection23 of the cam '23 then ahutsngni nst the detent 22, so thnt'the work ing shaft is stopped again after oxie-reyglittion. Which operations are performedby the working shaft during this revolution is determined hy-a number of magnets it), 11, 12, 13, 14. of which only a few are given a function in the drawings (see Fig. 6) while so far as their force sufl'ices therefor.

BEST AVAILABLE COP the remainder are shown connected to the controllingdisk merely to indicate that quite a number of magnets may thus be controlled it throws into engagement one of the clutches by which the motion of the working-shaitis imparted to the various operative members as will be explained later with Q reference to Fig. t3. For example the controlling magnet 10 starts printing and feed, while the magnet 11 brings about wordspacing; the magnet 12 brings about longi tudinal displacement of the type-wheel on the controlling shaft, and the magnet 13 the return of the carriage. Magnet 1 1 and furthe! magnets which are shown may be connected as pointed out above with similar devices for controlling other functions of the machine. This feature constitutes one of the principal advantages of in) novel mechanism. because of permitting the control of a great number of different functions and mechanisms from one controlling shaft.

The magnets may drive the operative parts directl without an auxiliary force in They are connected into circuit by the controlling disk 9. which, in this illustrative embodiment, constitutes a stationary controlling collector whose brush-arm 15 rdt'ates with the shaft 1. The windings of the magnets 10 to 14 are connected withthe segments of the collector; the current flows from the battery O to the slip-ring 145 connected with the mush-arm 15, over the segment located directly under the brush to the magnet connected therewith. and over a rotatiiw switch 29 back to the battery. This rotating switch is mounted on the working shaft A and closes the circuit only when this shaft has begun to rotate, which takes place only when the controlling shaft is stationary, and thus interrupts the circuit before the controllin shaft rotates again. Its purpose is'to avoid thetemporary excitation of all the controlling .of paper 7 when the hammer strikes.

magnets during the rotation of the controlling shaft and sparking due to breaking the ircu t at the controlling collector.

The types (t, b, c z", y, are provided on the periphery of tl1et \;'pc-wheel 3. That type which is exactly in front of the printing hammer G is printed on the sheet The types ar arranged in several rows oneabore another so that when the type wheel is axially shifted a short distance on the shaft 1 a ditlerent row of types is placed in front of he. hammer. This shifting of the type wheel not shown in the drawings. since it does notv form part. of my ,present inventicn and since it in re way aids the exphr nation and understanding of it. in all posill llf oi the "outrolhng shaft in which a I I t i l t I i l type is located in front of thehanin'ier the ln-ush-arm l5 conducts the current to the. lone contact segment which is connected with th magnet 10 and brings about printing: and teed. When the brush-arm is on one of the contacts 9, however. no printing ta kes place as the electromagnets 11 to l -l connected with these contacts bring about other operations. Therefore, that part of the 'typowhcel which is opposite the ham mer in these positions of the controlling shaft is provided with no types.

' second stationary collector 4-. herein i called the continuation collector, is for energazing the arresting magnet 16 when the I controlling shaft is in one enactly predetermined positiou. lts segments are arranged in pairs. and two brushes 30 and 31 which rotate with the controlling shaft slide over them. The segments are connected to the combination switches 32 in such manner that thebrushes I30, 3 are connected in each position with a diil'erent pair of switches, by which they can be connected to a common line 137. in the illustrative embodiment six switches-32 are shown; as fifteen different combinations each comprising two members can be formed with six members, the collector has litteen pairs of contacts; a condenser 233 which is connected with the two brushes 30 and 31 over the arresting mag net 10 and over two sliding contacts 35 is used the source of current. A second rotating switch 3 2 which rotates with the working shaft 24 connects these sliding contacts in its rest position. The circuit is closed at the moment when the brushes 30 and 31 contacttwo contact-pieces whose appertaining switches are closed. The arresting magnet 16 then energized for a short time by the condenser 33 and the locking lever 17 sto as the controlling shaft and releases the worlting shaft. The latter shaft closes the circuit for the controlling magnets by means of the switch 29, charges the condenser over the sliding contact-pieces 3.6 by means of the switch 34, and releases the controlling.shaftby means of the. 'Bai'h 25.

In order to stop the controlling shaft in a predetermined position two of the combination switches 32 mustbe closed, which can he done either by hand or by a r egj ste rbandt The switch arms carry projections 38 which slide over the traveling register band 39. As soon as a. hole in this band arrives under them they enter into the same, whereby the switch in question is closed by gravity or other suitable means known in the art.

As long as the working shaft-2 1: is arrested by the locking lever 17- the friction clutch through the medium of which it is driven must slide. The entire energy which otherwise serves for driving the operating memhers is constantly dissipated. Furthermore, the torque constantly exercised on the shaft;

com and the detent so that an. apprecinble force is requisite for withdrawing this detent. For this reason it is preferable to connect a. detachable coupling between the wonlcing shaft and its driving member. Fig. shows such a coupling. lhe ratch et 40 is constantly driven and rotates loosely onthe working shaft 2.4. The arm 41 curryinga pin l2 and a spring this fast. on the working shaft. A locking lever -13 having one end forn'led as a pawl is fulcrumed on the pin and under the influence of the spring l t tends to engage in the teeth of the ratchet. but as a rule itis prevented from so doing by the detent, of the lever 17; as soon as this is retracted, however, the locking), lever 43 ei'igages with the ratchet, is driven thereby and with it the arm 4:1 and the working shaft- :24. As soon HS one revolution is finished the lever 43 is stopped by the detent 22; toting further the lever 43 is then removed from the ratchet, the spring 6 4- is tensioned and the working shaft. 2% remains stntioir' cry. If this shaft were now no longer sub jected to any torque the spring would tend to bring about the engagement of the pawl and ratchet, and continuous rattling of the two parts one on the other would be caused. This is avoided'when a sliding clutch (represented at 212, Fig. 6) between the working shaft and the drive constantly transmits a torque sufficient for keeping the spring 44 tensioned. In order that it be not tensioned 'too much and that the line from thenxis of the shaft 24 passing through the fulcrum 42in the point of contact of'the lever 43 with the stop be not materially bent, I

provide on the arm 41 a stop 4-5 against which the lever 43 beers.

The sliding clutch which may be of any suitable construction requires only little friction as it does not transmit the torque to the o ierstive members of the machine; it can be entirely dispensed with when the arm 41 is held in its disconnected position by a snap roller 46, shown in Fig.3.

The six combination switches 32 and the combination collector l in the described illustrative embodiment enible the shaft to be stopped in fifteen different positions. The number of positions and the manysidedness of the machine is, however, materially increased when the switches 32 are formed as double pole switches and when, instead of two, any desired number of them are reversed for each symbol or character. When six double pole switchcsare provided 2 :64: various controlling positions are possible.

Fig. 4 shows how the combination collector is formed and connected'with the double pole switches in this case. The pivot points of switches 51 and 52 and of and 5% are electrically connected respectively owing to the arm 4C1 roi l l 5 fully as possible.

The conzhiimtion collector 58, shown in Fig. 5, a port of Whose de velopedperiphery it) comprising the seg ments 60 to ($6 is shown in Fig. 4, rotates on the shaft 1 in the direction indicated by the arrow under the statiorniry brushes 31. Of these there are in all eighteen, 2'. 6. one set of three for each of the double IJOlt switches 50 to The two'outer brushes of each set are connected with the contactpieces of a double pole switch. and the mid-' (lle brush conducts the current to the next; segment of the collector, as clearly shown. The segu'ients are so arranged on the collector that they connect either the one or the other of the two outer brushes of one with the middle one and, as will be readily understood, the circuit is closed when each of the six switch-levers 18 directly connected over one of its contact pieces and a brush to a segment of the collector. In the drawing the. collector is shown in a position in which the circuit is closed when the switches are in the position shown. The current flows as follows:- from one pole of the condenser 83 over the pair of brushes 35 and the switch 34: to the double pole switch 50, then over the segmerit-s60 and (31 to the double pole switch 5.1, to the double pole switch 52, over the segments 62 and 63 and the double pole switches 53 and 54: to the segments 6t. and 65,over the double pole switch 55 and the arresting magnet 16 and back to the other pole of the condenser. Consequently, by employing double pole switches 50 to 55 instead of the simple switches 32, the number of possible positions of the controlling shaft is increased from fifteen to sixty-four. Now when some of these positions are used in the above-described manner for adjusting and printing types, and others for adjusting operations, a part'of the type-wheel reu'uiins-empty as shown in Fig. 1. This is undesirable beciiuse the type-wheel should be of small diameter as iossible on ac count of a clean impression, and consequently its periphery must be utilized as This defect is obviated when the number of type-adjustments is made equal to the number of the working adjustments (in the present instance thirtytwo adjustments ofthe type-wheel and thirty-two adjustments of the controlling dislg) and these are arranged alternately over the periphery of the controllingshaft. The types are in this event distributed uniformly on the type-wheel, and the periph cry of the type-wheel can be fully utilized. Such an arrangement is shown in Fig. 8 in which the type-wheel, the controlling.collector and the ratchet for arresting the controlling shaft are shown developed. The type-wheel 3 has the'types arranged in three rows one above another, the top one slides ov r the the letter 0 advantageously with a combination collector according to provcment consists in the ratchet 5 the-same number of functions.

By shifting thc type-wheel axially on the shaft each otithe three rows can he brought 5 in from of the printing hammer whose position is indicated by the cross-hatched square H. The type-wheel 3) rotates with the crmtrollineshaft. as also the brush-arm 1:3 and the ratchet 5. The brush-arm 1.5 "mients of the stationary controlling collector 122 8). All those segments located in the extension of the middle line of a type of the type-wheel are connected with the printing and feed magnet 15 10, while the intermediate segments are connet-ted to the controlling magnets 11, i... 1 3, 1 In the drawing it is assumed that the tooth lZ-l of the ratchet 5 is held by the detent 21. The letter 0 is under the 20 printing hammer and a segment, connected with the printing and feed magnet 10 is under the sliding contact 15. As soon as the working:' shaft ll begins to rotate this magnet is energized over the switch 29, and

is printed. But if the controlling shaft is stopped at the tooth 125, for example. the printing hammer is between the two letters (Z and e, as indicated by a dotted line in the drawing. An impression 30 is not made as the sliding contact 15 does not conduct the currcnt to the printing and feed magnet 10. but to the magnet 14 which starts any other operation of the machine.

The arr: ngement shown in Fig. 8 can be employed both Fig. l and also with one according to Fig. 1. Such an arrangement can be improved still more, as represented in Fig. 5. The iin for stopping the controlling shaft. having only half as many teeth. in the illustrative embodiment thirty-two, instead of sixty-four, and in the machine nevertheless possessing Namely, of thesis combination switches only five are used for determining the arresting positions of the controlling shaft, these switches being designed 17 on the drawing. These five combination switches thus give only thirtytwo arresting positions: in the case of each of them. however. both the typeavheel 211" is adjusted to a type and the controlling: collector Qto a controlling magnet. and for determining whether an impression of the type or the excitation of this controlling magnet is to take place the sixth combination switch 48 is used. In the position shown in the drawing this switch closes the 50 circuit of the printing and feed magnet 1 As soon as the controlling shaft 1 stops and the working shaft 34 begins to rotate the rotatinc switch :0 closes a cirruit from one pole oftl e battery 0. switch 48, printing and feed magnet to. wit h 20 and the other together pole of the battery, and a type is printed and the carriage is fed if the switch 48 is placed by the pressure of a key not. shown or bythe register band on its lower cont act.-

If the machine is used for particular l purposes, frequently elements are necessary which sometimes have to move a larger and .These mema predetermined point. or to adjust slides serving for justification. or for other purposes. it meshes with a pinion 101 keyed on a shaft 102. On this shaft is splincd conicalfriction wheel 103 which can he brought into engagement by a twoarmed lever 105 with a second friction wheel 104 fast on a shaft 104. The latter shaft is positively driven by the controlling shaft as will he explained later on with reference to Fig. 6. As loiig the two-armed lever 105 pulled by a spring 105 against its stop 105" the friction wheel 103 is inoperative. As soon as an electromagnet 1.00

which is connected to one of the contact deiinergized because the lever 1-05 is held' by a catch 10?. Then, as soon as the controlling shaft begins to rotate again, the shaft 102 is also driven and consequently the rack 100 is moved by the pinion 101 until the controlling shaft stops again. AS the controlling sha [t can be stopped at any desired place the rack 100 canbe shifted any desired distance. After this motion has ended the friction clutch connecting the two shafts 104 and 102 must-be disengaged; to this end. a cam 10S mounted on the working shaft is provided which temporarily releases the catch 1.07. so thatthe lever 105 is pulled by its spring back into its rest position before the controlling shaft begins tov rotate again. \Vhcn itfirst stops and the friction clut h is engaged, the catch 107 is released for a short time; but as the magnet 100 is still energized, the lever 105 remains in its engaged position.

In the actual machine,.this controlling shaft as shown in Fig. 6, is subdivided into three portions l,i, 1', which are connected with each other by means of three bevel wheels 205, 206, 207, of equal size so that these three sections rotate with equal 1 5 speed and so far as their function is concerned operate one single shaft. Section 1 of the controlling shaft stands vertical and has bevel wheel and ratchet wheel 5 splined to it, so that section 1 may be i 20- lon itudinally shifted in order to permit the chi ting cit-the type wheel 3. relatively to the hammer 6 (see Fig. 8).

Section 1" runs in bearings 266 and 209 and carries the combination collector 58 (see also Fig. 5) on' which the brushes 3.1, slide. These brushes are arranged in five rows, three brushes in each row,' as is shown at ill, in Fig. (i. where thebrushholders are omitted to render the illustration clearer. The brushes are connected with double pole switches 47. 4'7. &7, 47, 174"; the detail operation and connection of which has been described with reference to Fig. at but which connection is also shown in Fig. 6. Each position of the double pole switches 47. etc. corresponds with a certain position of the combination collector 58 at which the circuit is closed. Shaft Section 1 also carries brush holder 15 which glides over the contacts of tho controlling collector 27 which are connected with clectro-magnets 10, ll, 12 and 13 in the manner shown in Fig. 5. Arm 15 is electrically connected with slip ring 16 which receives current from the fixed brush 16;

The large gear wheel 203 carries bushing 213 which carries at its inner; end rat het wheel l-O shown in detail in Figs. and 3.

Switch 2!) cooperates with the brush pair 2!) and switch 34 with the brush pairs 35 and so, as shown in Fig. ()n shaft 24 are also mounted a number of cam disks and eccentrics which operate the se cral elements of the machine.

The arrangement shown in Fig. (3 operates as follows: The motor 200 permanently rotates through gear wheels 201 and 203', bushing 213 and thus ratchet wheel. 40. Also by means of the light friction coupling 212 a slight torque is transmitted to workingshaft 24 This torque, however, is counteracted by stop of lever-17' which is the equivalent of lever 17 in Figs. 1 and 5 and which is distinguished from the latter merely by its bell crank shape. Lever 17 is pivoted at 268 and is capable of being held in two positions by means of spring controlled roll 18. By means of gear wheel 202 all three-sections 1. 1, 1 of the controlling shaft are driven through the friction coupling 204 so that they rotate permanently. It may now be assumed that double pole switches 47, 4?, etc, and also switch 48 are brought into the position shown in tion of the perforated strip 39 (Fig. 5). As soon as now combination collector gets into the position shown in Fig. (5. a circuit is closed for the arresting magnet 16. The currentthereby flows from the condenser 33 over conductor 272, magnet. 1(i,conductor 273 to the first double pole switch 47, thence to the left hand brush 31 of the first row; to the segment. then in contact with the brush, thence over 'the middle brush of the first row to the middle brush of the second row, through the second segment to brush of the third row, contact segment, middle brush of third row middle brush of fourth row. right brush of fourth row, switches 47 and 47, right brush of fifth row, middle brush of fifth row, conductor 271, brushes 35 (which are then conncctcd by rotating switch 34), conductor 270 back to the condenser 33. The arresting magnet 16 energized thereby and attract? its lever 17 so that its detent 21 engages. with ratchet wheel 5 which rotates as previously mentioned with section 1 of the controlling shaft. Thereby all three sections 1' 1 and .1 of thecontrolling shaft are By such movement of lever l7- lever 43 (see also Fig. 2) released so that it can fall under the tension of spring 44 into E ratchet wheel 40 whereby it couples Working shaft 24- with bushing 213 so that now working shaft 24 is positively driven.

lnthe present description. it assumed now that change-over switch it? (Fig. 5) is in contact with its upper contact. &8. Rotating switch 29 then causes the closing, of a circuit which energizes printing and feeding magnet 10 which is shown in Fig. 6 without its electric connection. For the printing of the adjusted type an eccentric ill is provided on shaft 24. With this eccentric cooperates roller 21:") which is carried by a lever 21G pivoted at 217. Lever 216 is pressed into contact with eccentric 214 by means of 5 ring 218. Moreover lever 216 is normally locked by a pawl 220, so long as its nose 221 is in'engagement with a corresponding member 219 of lever 216. Pawl 220 is pivoted at 222 and held "in engagement with nose am by means of a spring 223. As soon as magnet 10 is energized it attracts pawl 220 and thereby. rcleases lever 216 which now is brought into operative control of eccentric 21 i. Lever 216 has pivotally attached to it a rod 2H which is suitably connected with a printing hammer (5 (not shown). so that the latter is operated thereby to print the type. The feeding; oi the paper carriage is eiteclcd by nieans ot eccentric 22 t likewise mounted on working shaft 52%. lever 222i pivoted at -ZZZ-carries a roller which is held in engagement'with eccentric 22-l means of spring 228, lever 226 however being like 1216 held in inoperative position by means of.

pawl 230 which engages lever 226 with its nose 231. Also pawl 230 is attracted by maginct 10 when the latter is energized so' that also lever 2-26 is released and brought into operative engagement with its eccentric 224: so that the carriage may be operated by a rod 245 pivotaliy attached to lever .226. The carriage like the printing hammer .has been omitted in Fig. 6 since their detail construction is immaterial for the explanal tion of the. present invention Of course ec-' ccntrics 214: and 224: are timed relatively to each other so that the printing and feeding do not occur at the same time. but' sac; cessively.

This collar is axially movable b means of lever which spring controlled by means of spring 254. and operated against the tension of this spring by means of magnet 12 when the latter is energized as mentioned before.

If now magnet 1-. is energized lever rocks on its pivot and thereby throws the two tic-- tents into engagement and causes the rotation of cam or eccentric 247. This part of the structure is illustrated only thus far since the connection between the eccentric and shaft section 1 maybe of any convenient form to bring about the desired result. The last mentioned construction is immaterial to the present invention. lt may be stated merely that by the shifting of shaft section 1 the type wheel. a fraction of .which is shown at 3 in Fig. 8, is axially shifted with shaft section 1 so that the different sizes' ot' type or numerals may be brought into line with the printing hammer. A particular convenient arrangement is shown in my U. S. application, Serial No. m n? filed July 22, 1912.

When a line of the printed matter to be produced is completed the carriage musti he 236. Pawl 24a is held in this engaging position by means of sprmgi 243. Now as soon as electromagnet 13 which is in operative d stance from pawl 240 is energized when the controlling collectoril (Fig. 5) closes ement with nose 289 of lever the circuit for this magnet, pawl 340 rawn otli' nose 239 so that eccentric 23 can operate lever 236 and so that its movement in turn can be transmitted by means of rod 246 pivotally attached to lever 236 to the carriage. The detail construction of the connection between lever 236 and the can BEST AVAILABLE COP riage is, as the carriage itself, not shown since it does not form any part of my invention; The illustration in Fi. Got the various movements which control the movement of the main elements such as the paper carriage, the hannner and the like, are only shown so far their connection with the subject matter of my present invention is concerned, and it may be stated that inthe same manner in which the eccentrics and movements ust described are controlled from workingshatt' any suitable number of similar. eccentrics may be arranged on this shaft for controlling devices connected with themachine and necessary for its operation. Such eccentrics are controlled by electroinag'ncts in the manner just described, the magnets being energized by the circuit arrangements shown in Fig. 5. which. to gather with the arrangement in Fig. (3. illustrate the general principle on which my invention based.

lVorking shaft 24 further carries a snail cam 25, Fig. (3, the elevated portion of which is denoted with 25 in Figs. 5 and (3. in Fig. 5 the connection between this cam and lever 17 has been illustrated merely diagram I maticallv to indicate thatthcre is a mechanical connection between lever 17 and the cam. wher as in Fig. (3, th actual movement as employed in the machine is'illustrated. .ln this latter figure itwill be noted a longitunally slidingbar it; is disposed adjacent to and in parallel to the plane of cam and is also located adjacent to lever 17. The bar is spring controlled shown at 26 so that roller 26 attached at its upper end maintains contact with snail cam Adjacent to lever 15 bar 26 carries a pin 2? in the path of which lever 17 is located when bar 20 moves longitudinally. The arrangement of the elements just described is such that when lever 17 in engagement at 21 with ratchet wheel 5 as previously described. it is disengaged therefrom by pin 27 of bar 26 when the latter is drawn upward by elevated portion 25 ot' cam 25 when the.

latter rotates with shaft This releases the controlling shaft which as previously described was locked by lever 17' through the energizing of magnet 16. The releasing of this shaft and a drawing upward of lever 17 simultaneously throws portion 22 ct lever 17 into the path of lever 43 which to l a I tates with working shaft 24 and upon engagement of lever 23 with stop 22., the former disengages its other end from ratchet wheel co and thereby nncouplesworking shaft 5%- ti'rom bushing 213 and thus from ,ear wheel 203. In the mean time the rotating switch 34 which has rotated with shaft- 24- has, during its rotation recharged condenser 33 by closing a circuit through battery B over brushes 86 (Fig. 5).

The controlling shaft drives with its see-- a plurality of segments fast of said set; a source of current and! an arresting which transmit the notation to another pair of miter gears 26: and 264. Miter gear 264 fastened on shafii' IOt previously mentioned with reference to Fig. 7 where the other end of shaft 1 0% is shown. This other end, Fig. Tillu strates, carries a friction bevel wheel l0-t for the purpose previously described. Now working shaft 24 carries a cam disk 108 also previouslydescribed in connection with Fig. 7. -This disk is shown in Fig. 6 near the right hand end ot'shaft 2.4. \Vhenever a coupling between friction wheels 103, and 104-, in Fig. 7. has been brought about/by n'lagznet 106, this coupling is loosened at/the desired moment by means of cam disk [108 in the manner previously described. i
