. T ,gll whom it' may concern.-

Beit'known that I, SAMUEL J. SEIVFRIED, a citizen of the United States, residing in Chi cago, in the county of Cook and State of Illinois," have invented a new and useful Improvement in Type'Writers, of which the following is a specification.v

In this invention I have endeavored to .pro- 1 duce a durable, eflicient, and simple machine in which the type are carried upon cylinders adapted to be both rotated and shifted to bring the different type into printing position. Y

Theinvcntion is an improvement upon previous machines of this class, and is especially adapted to be used where manifolding is de shed, and some of theprincipal changes made from prior machines have had this object primarily in view.

- Iii my improvement I move the type-cylinder against the paper with considerable force, so that the impression may be carried through the several thicknesses used in manifolding withoutdifliculty and produce the-same effect as is obtained from the type-leverof the Rem-, ingto'n machine. This'result is secured by mounting the cylinderin a frame supported upon a pivot .whose axis is parallel to that of the cylinder and swinging said frame with a 50 quick movement to bring the cylinder against the "paper. The construction which I have adhpte'd is calculated to retain the cylinder thoroughly under control during the swingiug movement and to avoid any displacing of it through inertia or centrifugal action due to the swinging, and I prefer to position it verticallyand to support the frame upon vertical pivots, so that it may move horizontally. The invention further includes novel means forswinging the lrame and mechanism for retating and mechanism for shifting the cylinder to bringthediiferent characters into printing position. v v In order to reduce to the minimum the 4'5 mperor rotation'nnd' shifting by the type- 1 cylinder necessary to bring allthe characters 'iu'toi play,;T prefer, insteadof the single type cylinder heretofore einployed,.to use two eyl-. indera each of which bears a'portion of thetypejcharacteraandto mount such cylinders in separate swinging frames, such as that already alluded to, the several keys beingin its bearings. The brackets stand normally Serial 110.471. 004.- (No more.

adapted to-operate only'the cylinder which is' furnished with its'corresponding type. Herein is another important feature of the invention. I p I All these points of improvement are fully set forth below and also disclosed in the drawings, and in the latter- Figurel is a plan of the machine.- Fig. 2 is a vertical section on the line 2 2-of Fig. 1. 1 Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4 is a horizontal-section on the line 4 40f Fig. 3. Fig. 5 is a diagrammatic view illustrating'the type-cylinder frame and the devices for actuating it and for-moving the type-cylinder to present the desired char acter. Fig. 6 is a section of one of the ribbon-' spools and its support. Fig. 7 is a detail. plan j of a portion of the paper-carriage, the clutch 7o whereby it is fed,and the devices for opening the clutch, Fig. Sis a front view of the carriage. Figs. 9 and 10 are sections of the car-. riage on the lines '9 Oand l0 10, respcctlvely. Figs. 11 and 12 are detail'views' of a port-ion .75 of the machine. FHA. 13 is a perspective of a portion of the cyli'nder-frame-actuating mechanism.

In said drawings, A represents the frame of the machine, and B- B are the keys.

C 0 are the type-cylinders, two being preferably employed for the reason already stated, although all the characters can be placed upon one of them, if desired: The characters arearranged inany convenient 8 way upon tllecylinders, preferably in horizontal rows one above anothen' 'Each cylinder is vertically positioned upon a vertical shaft 0', having bearings in brackets'D D, 1 which are pivoted upon coinciding'short pivgo ots D D, supported in stationary parts of the machine, the axis of the pivots being parallel to that of the cylinder. The cylindershaft has freedom botlitb rotateand to slide v, at an angle, as shown, and being Joined at their outer ends by the cylinder-shaftxform a frame adapted to swing andto carry tliecyl inder forcibly against the-paper. v, Y

Y For the actuationofthe cylinder-frame in making'an impression the following construe tion may be employed: Aer sthe topof the series of keys or such of the as. are repl esented by the characters upon the cylinder,

ice

and in such close proximity thereto as to insure its being lifted by each and-every one of them when struck, is the rod E, which is secured in a lever E, fast upon the rock-shaft E Extending upwardly from this shaft is a cranlbarm'E connected by the rod E with the crank F upon a stationari'ly-supported v'ertical shaft F, carryinga cam E, which engages with another cam l5 upon the lower extremity of bracket D of the wheel-frame. These cams have a rolling contact with .one another, and when any of the keys are operated the consequent lifting of the rod E causes a rocking of shaft E and also a rocking of the vertical shaft F, and this results in the actuation of cam F by .cam F and in the swinging of the cylinder-frame from its normal to the operating position. The impulse thus given the frame is a quick one by reason of the nature of the actuating devices, and it also becomes more rapid as the cylinder approaches the paper, so that the impact or blow imparted is one which will insure any reasonable amount of manifolding. The are of-the cylinder through which the wheel moves is also of sufficient length to allow it to acquire considerable momentum and thus to insure anefficientimpression. Theframeisbronght back after each impression by the spring F and cord F winding upon' the pulley F upon the lower end of the frame.

The positioning of the cylinder on an axis parallel to that of the frame is an advanta gcous feature in that there-is no tendency by the swinging of the cylinder and frame to throw the cylinders out of position, as there would be'if the pivots were not parallel; but of course I do not wish to be limited to this feature except 'in such of the claims as are acters. The keys on the right side of the ma- 2 chine operate the cylinder upon that side and expressly confined thereto;

Where two type-cylinders are employed, they are located at either side of the impression-point and swing toward the same in opposite directions, and they are precisely alike, except that one hears one half of the charac' ters and the other bcarsthe remaining charthose n'ponthe left side operate the left cylinder. In order to avoid injurious contact by the cylinders with each other, which might occur if keysupon both sides of the machine should beistruck simultaneously, I provide upon each of the cylinders? axes rubber disks c, which are calculated to collide at such times t and prevent any contact by the cylinders with each other. e

In order to turn the cylinders to bring dif- .fcrcnt type into position "for action, I employ the following mechanism: lhe key-levers B of such of the type as require rotation of the cylinder are slotted downwardly from their upper edges, so as'to form an incline or cam b, adapted, when the key is struck, to move a cross-barrel either forward or back, according to the direhtion in which rotation is re quired. 'lhecams b incline some in one dikeys with a straight-sided slot b.

rection and some in the reverse direction, so as to give the proper movement to the bar Gr. Said bar is suspended by links 9 from a rockshaft G, journaled in the sides of the machine, and thelinks being rigid with the shaft the latter is rocked and lifts an arm G also fast on the shaft. From the swinging end of arm G2 extends upwardly a connecting-rod g,

joined to the arm by a universal joint g located in line with the axis of the swingingframe, and said rod is united at its upper end to a" crank G mounted upon'the axis g of a crown-segment G which meshes with a lantern-wheel G fast upon the axis of the typecylinder. With this construction it will be seen that the striking of the key will result in shifting the bar G either forward or back,

according to the direction of the cam hot the key, and that a rocking of shaft G will be caused thereby, which will lift arm G2 and crank G3 and oscillate the crow n-segment, and

the latterwill actuate the lantern-wheel and the type-cylinder shaft. of course it will be understood that the-keys of those letters which require no rotation of the type-cylinder are also made in such manner as to have no effect upon the bar G, and one method ofavoiding action upon said bar is by providing the It will also be understood that the cylinder is rotated back to its normal position during the return of the frame, inasmuch as during such movement the-actuating devices of the crown-segment are returned, as hereinafter set forth;

also, that the cams b are adapted to cause the amount of rotation by the type-cylinder which is requisite to bring the desired character into action'by giving the cams a greater or less inclination. t

For the purpose of shifting thetypecylinderalong its axis. in order to bring the characters located in different rows into operating I position I employ the following: Such of the keys as do not' require this operation of the type-cylinder are shortened, so that they do not come in contact with a cross-bar II, which is suspended over the keys by links 7L from a rock-shaft H, journaled in'the sides of the machine. Those of the keys, however, which do require the shifting of the type-cylinder are beveled upon their ends, as at I), and thereby enabled to swing the bar If upon its links and rock the shaft ll and cause a depression of the crank-arm H fast upon said shaft, and a swinging upon itspivot ll: of le-' ver H on which the end of arm ll rests.

The front end of lever H sets under the star- Wheel 11, mounted upon the shaft of the typecylinder, and is adapted to apply a lifting power to the shaft by such connection After the impression the bar If ismoved back to its normal position, as hereinafter stated, and

this results in the withdrawal of the lifting power from the type-cylinder shaft, so that it falls to its normal position by gravity; The contactpoint of arm ll with'lever I1 is 10 ca'ted in the axial line of theswinging frame.

The lever E at its rear end is notched upon "its under surface with inverted V notches, as

shown at e. These notchesare-so located as to insure their setting down over thecrossbars G and II, whatever may be their position,'when the lever falls to its, normal position,'and they are adaptedto move said bars to theirpositions of rest, as will be readily seen. 'Of course the lever E is raised so as not to interfere with the bars upon the striking' of the 'keys, and this movement is timed slightly-in advanced the movement of the bars.

In order-to bring the cylinders into accurate registeringpositionat the time of making the impressio ns,'I provide the following devices; Upon theshaft of the type-cylinder is a star-wheel H already mentioned. [The notches of thie' whgel are Y-shaped, so that as the frame approaches the operating-point theywill straddlea stationary vertical guidepin J and enable the latter as it enters the,

notches to turn the'cylinder shaft slightly, if that should be necessary, and properly center the type to be impressed with reference to. the

printing center. This centering ofv the cylinder preparatory to the impressions is jspe-' -ciall y important, because the diameter of the paper-holding platen varies with the number of thicknesses of papier present upon it, and such variations result .in bringing forward *the plane of thepjrinting'center with each ad,-

ditional thickness of paper put upon the platen, and such changesin the plane at which the impression is 'made would, unless means were taken to prevent the same, result inzvariations in-the spacing of the characters.

By my centering device, however, the type, are brought absolutely and nnerringly'in 4 front of the printing center, regardless of the thickness of paper onthe platen, and the evil referredftb is thereby overcome. I 'also e mploy means whereby the horizontal alignment of the impressions may be preserved with certainty. These means are'adapted to position the type-cylinder accuratelyin the proper horizontal plane, and consist of two pairs of guides J"and J having their frontends beveled away from eachother, so that the points of the starwheel Hf will enter between them and thus be liftedo'r'deprssed to the'proper planeto secure'a'ccnr'acy of alignment. lwo

pairs of'these guides'ar employed, one pair acting upon the star-wheel when the cylinders ha'ft is swinging in its'normalplane and the other pair acting when the shaft is swinging in its elevated plane. Of these "guides the under one .l of each painis ri'gid, sothat it will act positively in lifti'ngthe cylindcr. The

upperone of each pair J is preferably made of spring metal, 'so' that it may yieldto the impact of the starfwh'eel at the instant of, con

tact andyet possess power enough to force thew h'eel down upon the under guide'in seasonfbefore the'maki'n'g of the impression.-

" 'lhe se upper guides" arealsoadaptedto overcom'efany rising mombntum which the starguides.

the replacing of the spool.

wheclma f acquire by contact with the under" I now proceed to describe the mechanism for controlling the movement-of the ribbon;

When the crank-arm E is actuated by the striking of a key, it encounters a pin or crossrod 2' upon the lower end of a lever K, loose upon a cross-shaft K, and swingssuch end of the lever forward. -Attach'edto this lever is a spring-depressed pawl" K, which meshes with the ratchet-wheel K and through said ratchet-wheel rotates the shaft K Mounted nishd with two bevel-faced cams L,',- which A are adapted to enter under the collars L mounted uponthespool-shafts, and liftthem sn'flicientlyto effect he disengagement. The cains are so located as to render them alternating in their action-that-is to say, when the slide is moved in one direction it willlift one spool-shaft'and when moved in the .op-

posite direction it will lift the other one; By this-construction I am enabled to reverse the movement of the ribbon whenever necessary by simplymoving the slide,and-the latter is preferably provided-with an arm L whereby it may be moved, and which extendsi'throngh' the front of the case, so as to be readily accessi ble. It will benoticed in Fig. 3 thato'ne of the spools L is disengaged and stands 'inja" somewhat higher planethan. the other spool, so'that the ribbon L is drawn from one :to the other in a direction inclined downward.

'ros

from the-horizontal. This inclination-is, of

course, reversed when the other spool is winding up the ribbon, so that the impressions are not likely to be made upon the same points in v the ribbon and the amount of work of which the latter is capableis therefore increased,

The ratchet K is prevented fromnnoving .backward by'the spring-stop K.

For the purpose of holding the ribbon in' place'on the shaft I employ the "construction particularly illustrated at'Fig.' The upper end of the spool-shaft is hollowed out, as shown 'at m, and in the bottom of this recess I secure a spring-wire m, 'whichextendsto the top of the shaft, where a=ball M or other enlargement made sloping upon its under surface is secured to it. t The spring has a tendency to'keep the ball in' position where it projects over the spool somewhan'and in this way the ball is caused to exerta snfli cient holding powt pon hespm 1 to keep 'itin place. This holding power is, however,

kindv is requisite when the; spool is tobe changed orremoved. The device is also'a-utomatic in resuming its acting readily overcome when the spool is lifted by ,hand,*so that no preparatory ,work'of "any position upon The devices which control the movements of the carriage are also actuated from the lever-K, already described, and which, as we t have scen,'is moved at each stroke of the key.

From the upper end of this lover a connecting-rod N extendsand is joined to the lower end of a'swinging lever N stationarily pivoted at its center and engaging at its upper 1 end with the usual escapement-wheels l)! N.

n, is the spring acting upon the loose wheel N This escapement being of the ordinary construction, I do not enlarge upon its descriptiou here, and it acts upon the carriage in carrying the the ordinary manner through the medium ofthe normally closed clutch O'upon the shaft escapement-wheels, the pinion 0', also upon said shaft, and the rack P, carried by the paper-carriage, the bed of which i is shown at P.

The spacing-key is shown at B, and it swings the arm 13" forward against the pin or rod '11 and thus, through the mechanism already described, carries motion to the carriage. i

For the purpose of releasing the carriage, so that it maybe moved by handin either direction,l provide it with a longitudinal bar Q, which is movabiy secured tothe carriage-bed bystudsqpassing through the diagonal slots q' in the bar. ,Along its under surface this liar carries a wire-guide g which is carried down far enough so that its'horizontal'portion shall lie in theannular groove 1 of the movable part of the clutch O. \Vith this constructioi when it is desired to release the carriage the operator pushes upon the pro- ,--jectin;; cud q? of the bar Q, and thereby slides the bar and its guide-wire in a diagonal di-- rection and to the extent permitted by the slots.- This movement is sutficient to cause a a drawing apart of the clutch O, which leaves the carriage free to move to any extent desired.

The carriage-bed is provided with uprights P at each end, and the impression roller or platen P is supported in 'a frame which is ournaled inthcse uprights. This frame consists f the vertical end pieces P in which the shaft 1 of the impression-roller is journaled, and the cross-bars P" and P The frame is also connected by two arms P to .a

v shaft/P j ournaledin the uprights P and to whichthe arms P are rigidly secured, and. as said arms arepivotally'joined to the ends [of the'pcross-bar I the forward part of'the carriage is free to be raised. This raising is in part'for the'purpose of bringing the impression-platenupou a level with the;upper- 'case letters, which are located on the upper part of the type-cylinders, and so that such let- 'ters'. may be impressed, and hence it is dc-' sirable thatthis movement should be in a straight vertical plane'for at least apart of the distance, in order that the platen in its raised position may occupy the same position as it does when relative to the type-cylinder in'its lower position, in which the lower-case characters are printed. To secure this vertical movement of the platen, its journals are made to pass through guide-slots I in the uprights of the carriage. As will be seen from thedrawings, these guideslots are vertical for part of their length, so that the platen is compelled to retain its distance from the type-cylinders during the portionlof the movement necessary to .position it for upper-case printing, and this upward movement is imparted to it by mechanism presently to be described.

The upper portions of' the slots are inclined from the vertical and are intended to permit the further raising of the roller by hand for the purpose of reading the written matter or making corrections therein.

The platen is normally sustained by the bar- P, resting upon aroller "R, supported upon one end of a lever R, pivoted-to astationary cross brace ot the machine at 'r, and this lever is actuated to lift the platen, as already described, by the connecting-rod 1, extending from the end of lever B down to. the key R. This key is fast upon a shaft R and a second key It at the other side of the machine is also joined to said shaft, so that the lifting devices may be operated by either hand.

spring-stop s Trepresents the usual thumb:

wheel for rotating the roller in putting in" paper. I a 1 When the paper-carriage is removed from the machine, it is essential to retain control of the cord attached to the spring-drum which feeds the carriage, because if that is not done the spring of the drum is apt to be broken. To remedy this evil I have devised the following: U is the spring-drum, and u the cordor flexible connection whereby the drum draws. the carriage. The cord is provided at its end with the metal device shown at u, and which is preferably inv the form of a double eye, the two parts ofwhich are slightly in cllned relative to one another, and the cord is secured to one part. A stationary forked retainer U is'also'provided and located at thepoint where the cord should be secured upon the removal of the carriage. This retainer stands vertically with one of its limbs onzeither side of the cord, and with its limbs also bent over toward the direction in which theeye approaches it. The carriage is provided with a hookY, open toward the'eyeand moving in a line with the upper-opening thereof. By these devices it will be seen that it the eye and cor-dare in the" grasp of the fork, as" shown at Fig. 11, and the carriage sea-126:

is shdback into the machine the hookupon the carriage will catchin the upper opening of the eye and thus be automatically conto betaken away. The retainer maintains its holdupon the cord until the carriage isreplaced. I

They centerguide W isshortened, so as not to cover the printing. I

a It will be'noticed that by locating the universal joint 9?, vwhich connects the. swinging end of arm 'G 'with the con'necting-rodg'; op-l crating the crown-wheel in rotating the type-- cylindeiyin the axial line o'fthe swinging" frame I, avoid imparting any rotation to the cylinder during the swinging of the frame ex-.

' cept such as is required in the proper posimash line. 1

Inthe practical working of the machine I g aim to impart-both the necessary rotation and the necessary longitudinal"movementto'the type cylinder'during the first portion or the ,tioning of the character to beimpres'sed. The 39 universal joi'n't"in=- this location is also desir-. ably free from friction or binding, much'more so than it would be if-located at-one sid'eof swingingmoyernent of the frame, so that the cylinder will be in a state of rest relative to a and be inhettercoudition to have -its-.inaGcu-,
