converted from the character of'machine' in which the type bars or'other operated parts are i mpellcdby means other than the power used in depressing the keys, or force with which the keys are depressed into a machine of that character in which the operration. of the operated parts is eli'ected by the power or force with which the keys are depressed or vice versa.

.The Cahill electric typewriting machine is a representative of the first type of machine referred to, while the Remington typewriting machine is a representative of the second type *of' machine.

The many advantages possessed by a convertible typewriting machine over either the type of machine in which the operation of the type bars is dependent solely upon power auxiliary to that employed for de-.

pressing the keys or the type of machine in which the operation of the type bars is. dependent solely upon the power employed for depressing the key levers, will suggest them selves; butamong others, it ma be well to mention that a machine ca abe of being converted as described, avoi s'the objection which is so often urged against the type of machine which I have desi noted as of the first class, this objection being that the machine is rendered inoperative and useless the moment the auxiliary power is cut oil for any reason.

Another primary object of the present invention is to provide a simple and satisfactory electrically operated mechanism for impelling the type bars to the printing point upon the depression of the keys pertaining thereto which includes means for permitting the. return of the type bars and the keys to their initial positions independently of one another.

Another object is to provide a typewriting machine having pivoted type bars with electrically operated mechanism .so positioned that long link connections may be interposed between said .bars and the oper-" ating levers coupled thereto to reduce torsional strain upon said links and there through lessen the strain upon the type bars which tends'to pull the same out of their positions.

Other objects of the invention will suggest themselves when't-he same is more fully explained. v y I VV-ith the objects specifically'set forth and many others in view which will appear and befully appreciated when the invention is made clear, the same comprises the novel construct-ion, combination and arrangen ient of parts which will be hereinafter described and particularly pointed out in the claims.

Whilothe' invention is susceptible of vari-l ou's modifications I have illustrated in the accompanylng drawings what I now con ceive to be the preferred embodiment of the" same. I

In these drawingsFigure 1 is a vertical sectional View of a typewriting machine embodying my invention showing the. parts in the positions assumed thereby when the machine is set to be operated by means auxiliary to that. employed for depressing the keys. Fig.2 is a similar view-showing the parts in the positions assumed thereby when the machine is set to be operated solely by*' the power employd in depressing the keys. Fig. 8 is an end elevation of one of the arms employed in the improved mechanism. Fig; 4 is a similar view of a modification of sold arm. Fig. 5 is a perspective-view of one of the push fingers. Fig. 6 is a detaiIpers ective view. Fig. 7 is a detail sectional view of a modification of my invention, and, Fig. 8 is a plan view of one of the key lcvers em- .ployed in this construction .i

The invention is illustrated in thelaccom 'panying drawings, and. will be'hereinaiter described as embodied in the construction of 'typewriting machines having pivoted typebars, ascertain subordinate features of the invention have special reference .to this part'icula'r construction ofmachine, and presents special combinations with certain parts thereof, but it'will be understood that most of the primary features of the invention are applicable by tion, mechanism is provided for impelling the typebars to the printing point either by a power auxiliary to that employed for deressing the keys or by the power with which the keys are depressed. In-the particular embodiment of the invention illustrated in the accompanying drawings and to be hereinafter described, electricity is utilized as the auxiliary power, and the mechanism for utilizing the same to secure the operation of the machine will first be described, and thereafter will be described the converters and action of the mechanism when the machine is converted into one in which the type bars are impelled solely by force or power employed for depressing the keys. V I 1 For the purpose of accentuating the salient features of the invention in illustratingpbhe same as embodied'in the construction of typewriting machines hereinbcfore refelrn'edf' parts of, saith;

\ ranged to coact with the vertical arms u pivotally connected at their lower ends to to, certain of the well-known machines have been eliminated. i

In these drawings a section of the platen is shown at a, the machine frame at 0, 'two of the type bars pivoted to the upper plate thereof and'depending thereinto at 0, (Z, a buffer ring for the latter at c, and the keys at The key lever pertaining to each key f, preferably includes a lever proper g, having the key connected directly thereto, and an auxiliary lever 57 having the type bar pertaining to-the key coupled thereto through the intermediary of an adjustable link i.

In order to obtain a. uniform pull upon the type bars in the operation of the machine, the auxiliary linksare preferably pivoted in staggered relation to one another, those connected to one set of type bars represented by the bar (2, being pivoted approximately centrally ofthe machine at 2, while those coupled to the remaining type bars represented by the bar rZ are pivoted at the rear of the n'iachinc at z.

Pivoted directly to each auxiliary lever y near the frontend of the same is a bellcra'nlt lever m, the vertical arm of which reacts with the motor frame n to be hereinafter described, while the horizontal arm m of said leverconstitutes the setting or positioning member thereof. The levels at, when zontal position, having its side member ivoted at one end upon a shaft n" supporte in bosses or studs n while the free end of said frame is provided with a contacting surface a, extending entirely across the machine and; designed when the frame is drawn down, as will be described, to strike against the end of the vertical arm m, of the lever m positioned-in the path thereof, and depress the same and therethrough the auxiliary lever g pertaining to the positioned lever m and through the link 2' actuate the type bar coupled to the lever 9. One side member of the motor frame a is preferably provided with an angular extension or depending arm a, winch .is coupled by an adjustable link to the core of a horizontally arranged'sucking magnet r. The latter is arranged in a normally dead circuit including a generating units, stationary contact point 8', and a universal contact frame If carrying a contact point t, designed to contact with the point 8. The frame 1f, which is pivotally supported, preferably by arms 4: which are themselves pivotally supported by lugs E for a purpose to be hereinafter explained, is provided with a flexible arm extending to the rear of its pivot, carrying the point t and with a cross bar 6'- extending entirely across the machine arthe links 9 which carry the same. An arm u is associated with each link g, and the free end thereofjs normally held in a rearwardly tilted position by a spring 2/ associated therewith to normally maintain the shoulder a: of: said arms above and in engagement with the cross bar 25 and a shoulder 12' formed on said arm in engagement with a lateral extension m" on the free end of the arm of of the bell crank lever m associated with the lever pertaining to the lever f] to which the arm a is )ivoted. Each arm n is provided with an 0 set guide opening a designed to receive the end of the lever gpertaining thereto, and each lever is pro vided with a beveled portion, preferably the end thereof, designed when the lever is depressed, to coact with the end of the bottom wallot' said guide opening to throw the arm n pertaining thereto, forward against the tension of its spring u to release the contact frame and position lever m, as will be hereinafter described.

Upon the depression of one of the keys f, the lever g carrying the same is depressed, carrying with it the arm upivoted thereto, the latter being. in engagement with the cross bar 15 of the universal contact frame t, and with the extension m of the lever massocia ted therewith, and rocks the lever m of the contacting surface m of the motor motor frame at bringing the contacting surface a thereof into engagement with the end of the arm m of the positioned lever m depressing the latter, and therethrough depressing the lever g, to which said 'positinned lever m is pivoted, thus operatingthe type bar pertainlng to the key depressed,

through the intermediary of the link connection between said type bar and the lever g referred to. In the downward movement of the lever g, the beveled end :12 thereof contacting with the rear edge of the bottom wall of the guiding opening u of the arm it carried by the depressed key lever g throws said arm u forward against the tension of its spring 20 and thereby disengages the shoulders 'v and u thereof from the cross bar-t of the universal contact frame t, and the positioned lever m, respectively. As soon as the frame If is released, the same is returned to its initial position by the spring interrupting the electrical circuit through the magnet 1' at the points 8', t, thus deiine'rgiz--- ing the magnet and permltting the motor frame a to reassume its initial position under the influence of the spring n The lever m, upon being released 15 atonce restored to .positionby its spring 0 and the auxiliary lever g is restored to position by the spring g associated therewith.

The restoration of the parts described to .their initial positions takes place notwithstanding the fact that the key 7 may be held depressed but as soon as the same is released by the operator, said key and lever carrying the same is restored to position by the spring associated therewith. It will be particularly noted that the return of the keyand the'lever carrying the same, takes place entirely independent of the return of the type bar,'and thus should either said key and lever, or said type bar stick, it would not effect the return to their initial positions of the other operating elements.

After the-arm u is thrown forward against the tension of its spring a disengaging the same from the universal contact frame and the extension a of the lever m, said arm is held out of engagement with said parts until the key lever carrying the same is restored to its initial position, so that should the key lever'become stuck and thus hold down the arm u, the latter wilianot interfere in any way with the operation of the other keysof the machine.

To hold the-arm out against the tension of its spring at. until the key-lever carrying the same is restored to its initial position, the

front end or nose '0 of the arm u is designed to enact with the front end of the part'm or extension m of the latter. preciated that upon the arm a being thrown.

1 out, the lever g" at once returns to its initial position and that the nose u Willremain in engagement with the front .end of said part m or the extension wa thereof as long as the key lever g remains in its depressed position and as a consequence said arm u will be held forward so as not to interfere with the universal contact frame or the levers m carried by the other keys.

From the above description, it will be un-- derstood that the movement given to the finger key by the operator, serves to shift the arm m into position to'be struck by the motor frame and also by effecting the clos- It will be ap-- ing of the circuit, causes the magnet to be actuated. The magnet, whenactuated by the closing of the circuit, effects a movement of the-motor frame which, in' turn,- striking the positioned arm in, moves it and the auxiliary lever, to which it is connected, downward, the movement of the auxiliary lever,

through its connections with the type .bar,

causing the type bar to be actuated. The devices operated by the magnet to thus actuate the type bar, move independently of the movement of the finger key and return to initial position independently of the movement of the finger key.

As before premised, the present invention contemplates the provision of means for instantly converting the machine from one in which the mechanism interposed between the keys and type bars is employed for op crating the latter when-actuated by the depression of the former by power auxiliary to that employed for depressing said keys such as has just been described, into one in which said mechanism is employed for operating the type bars by the power or force used in depressing said keys. In the construction illustrated in the accompanying drawings, this object is attained by merely coupling the levers g to the auxiliary levers g pertaining thereto, so that the two operate as a singlepart or as one key lever. To this. end, means are provided for maintaining the arms a in their rearward positions with the shoulders '11 thereof in engagement with the upper faces of the extensions m of the levers m, the latter being thrown for ward to seat said extensions upon the upper edges of the levers g pertaining thereto, as indicated in Fig. 2. r

. As the universal contact frame If is rendered unnecessary in the converted machine, means are preferably provided for'shifting its cross bar 15 out of the path of the shouls ders n, and as the levers g, g, are coupled to move in unison, the springs associated with the latter are suilicient to restore said leversto their initial positions, after the same are depressed and released, and conscqucntly the springs g are rendered unnecessary and in fact undesirable, and therefore cneans are also provided for throwing said springs out of operation.

For throwing the levers m forward, and at the same time retracting the contact frame t, a rocking frame 1, ispi efepably provided, comprising side arms 4,; pivc tally support d in lugs 2, and a cross bar extending across the machine connecting said side arms arranged to the rear of the levers m to provide, when the machine is arranged to be electrically operated, a stop or rest for the arms m. The contact frame t is carried by the side arms 4, being pivotally connected to the same below the pivotal axis thereof. Any suitable means may be provided for rocking the frame 1 from the position shown in Fig. 1, into the position shown in. Fig. 2,

said'fiame when rocked into the latter tion serving to throw the 3 against the arins m of the levers m to hold the latter in advanced positions, the extensions m of the arms of thereof, coac't-ing with the edges of the levers g to provide stops for said arms and to'retract the contact frame a to withdraw the bar t thereof out of the paths of the shoulders 12 of the arms in While the bar 3 is preferably made use of to throw the levers forward to occupy their advanced sitions, said bar can be dispensed with so far as this function thereotis concerned as the armsu, when drawn down, aswill bearms m of thelevers m, an eccentrically journaled cross shaft '5 is preferably provided. This shaft as shown in the accompanying drawings in addition to providing means for holdingthe arms u in their rear ward positions also provides a stop for arresting the upward movements of the levers 9 under the\ ends of the return springs thereof. l

To avoid "lost motion in the connection between each lever gand the auxiliary lever arms 10- in lower posit-ions so thatthe shoulj g pertaining thereto, when the machine is set formanual operation only, means/arev provided for normally holding the levers g in a lower plane than that occupied by the same when the machine is set to be operated by power auxiliary to that employed for; depressing the keys, thereby holding, the

ago-scene 'ders o thereof will be maintained in direct engagement with the lateral extensions m and the latter maintained in direct engagement with the ed es of the levers y. To arrest the levers g on the return thereof in their different positions the cross sha tt 5, before referred to, is preferably provided with two stop surfaces 6, 7. The surface 6 also coacts with the links 24, and when said shaft 7 5 turned to bring the latter surface into action as shown. in Fig. :2, thelevers g are held in their lowermost return positions, and the arms u are held in their rearward positions. When the shaft 5 is turned to carry the surface 6 out of action, as shown in Fig, 1, the arms at are released and the surface? is brought into action to provide a stop for the levers g in a relatively higher plane than the stop therefor provided by the surface 6.

When the machine is arranged to be operated by means auxiliary to the power employed for depressing the keys, it is desirable that the latter have but a slight dip,- while when the machine is converted, as described, a relativelydeeper dip of the keys is desired. To this end an adjustable stop for limiting the depression of the keys is desirable,- and in the embodiment of this feature o'ifthe invention hereinafter disclosed, a stop bar 10, which is common to all 0% the key levers, is provided, this bar being eocentrically mounted bet-ween the sides of the machine frame, and being provided with two arresting surfaces 10", 10. When the bar is turned, as shown in F ig. 1, the surface 10 performs the functionof the stop, and but a slight dip of is provided for.

To obtain a maximuinfdip', the bar 10 is turned to brin the same into the position illustratedjn ..'ig. 2, in which position the surface it) provides the arresting surface. When the machine is set for manual operation only, the auxiliary lovers 9 are coupled by the arms a to the levers g'pertaining to the same, so that the two move as one part, and consequently upon the depression ofa key, the movement thereof is directly transmitted to the type bar pertaining to the same, the'electrically operated mechanism remaining inactive.

In Figt'T a modified embodiment of my I invention is illustrated. In this form of the invention, the arms which are utilized to set in action the electrically operated incchanism upon the depression of the keys-pertaining to the same, when the mach-ice is set to be electrically operated, and for directly Operating the supplemental levers coupled to the typebars on the depression of the key levers pertaining thereto, when the machine is set to be manually operated, are supported by and depended from members employed; for actuating the universal contact frame and for positioning the'push finger; the free I offset p ends of such arms having detachable engagement with the kdy levers with which 'the same are associate Referringparticularly to Fig. 7, the key levers are indicated by the letter 9 with each of which a bell crank lever h is associated, the latter being mounted upon a commoncross-rod it", supported at its ends in opposite sides of the machine frame. To the free end of the horizontal arm of each lever 72, an arm at is pivotally connected, the free end of the latter being provided with a shoulder m designed to engage with an offset or an abutment g projecting laterally from the key lever associated therewith. Each key lever is also provided with an offset finger g in advance of the 'abutment carried therebywhich provides a guide for the free end of the arm m associated with the same, as will be hereinafter de scribed. Pivoted at its lower end to each supplemental lever 7 is a push finger 0 coupled by a link 12 to the vertical arm of the bell crank lever 71 pertaining tothe same; the connect-ion between said link and the vertical arm of the bell crank lever h being preferably a sliding pivotal one formed by an elongated slot in the link in which a pin projecting laterally from the end of the vertical arm of the bell crank lever works. The push fingers 0 are, as in the embodiment of my invention first described, held out of the path of movement of the motor frame 1" which is actuated by the sucking magnet 8 upon the closing of the normally open electrical circuit which v includes said magnet, ing unit If, rheostat t? and universal contact framet. The bell crank levers it are normally held up in the position in which the same are shown in Fig. 7 by a suitable spring, the free end of .each arm m is held in engagement with the pertaining thereto by aspring m interposed betw'een'thc pivoted en oi. said arm and the bellcrank lever 115 carrying thejsame, and the-push fingers 0" are normally held out of the path of movement of the frame 7 by a spring 0 which is interposed betw en each of said fingers and the supplemental lever g carrying the same. Upon the depression of the key lever 9 the bell crank lever h pertaining thereto 'is rocked in the direction indicated by the .arrow, through the interposed arm m The horizontal arm of the bellcrank lever coming into cngagementwith the universal the line t, a generatcontact frame serves to depress the latter 'onsly positions the finger 0 energized upon the closing and thercthrongh closethe electrical circuit. The movement of said bell crank lever through the interposed link p simultanepertaining to the key lever depressed. The i'nagnet being of the electrical circuit as before described, actuates the depressed key lever g vmentof the horizontal If, fixed contact point.

" until the pins, m

the

motor frame T which depresses the supple:

mental lever g pertaining to the key manually operated, through the intermediary of the positioned push the downward movement of the supplemental lever the inclined end 9 thereof comes into'contactwith a lateral abutment m on the arm m which is held down by and serves to forward, disengaging the free end thereof from the oil-set g of said depressed lever. As released the bell crank 'lever h is restored to its'initial position by its spring releasing the cont-act frame which is also restored to its initial position as the electrical circuit is broken when the'contact frame is released and thus the positioned push finger is freed, the latter .being also restored to its initial position by a spring associated with the same.

As .in the first described embodimentof my invent-ion, to set the machine to be operated manually, is shifted out of the path of its operatin members, and the key levers are arrange to be operated in alower plane than the machineis setto be electrically operated. The contact frame. as shown herein is eccentrically mounted or pivotally supported from a rotatable disk It, the operation of which throws the cross-bar of said contact frame, into and out of throw said arm m arms of the bell crank levers It.

As in the preferred embodiment ofmy invention a rocking frame 9" common to all the key levers g is-provided for limiting the return movement of the key levers. When this frame is turned to bring the working face 5/ thereof into coaction with the key levers, the latter-are forced down of the arms in are seated in recesses in the upper edges of the supplemental levers g. The supplemental levers are thus, through the interposition of the arms m and pins in depressed when the key levers are actuated independcntlyof the electrically operated n'iechanism.

The construction and operation of my typewriting machine will be readily understood npon reference to the foregoing de scription and accompanying drawings, and it will be understood that the parts and;

combinations recited be varied iiithiii a wide range without departing from the spirit of the invention. It will be also understood that while thc invention is herein shown and. described as a part of a typowriting machine, I do not intend tolimitit to use in such machines as it is evident that it may be applied to any key controlled inn--- chine in which an operated part is caused to impinge upon its objective. point as for instance in linotypc or matrix making mafinger.
