- spiral cams k k On the opposingfaces of the lower clutch-head d and the lower disk of the slide K are secured spiral cams k k, which bear against each other.
- the purpose of the bow-spring C is to causethe type-wheel to strike the platen with an elastic or yielding blow and to'avoid the necessity of. accurately adjusting the position of the type-wheel frame relatively to the platen. Owing to the high speed of the driving-shaft B, the cams k k will repeatedly actuate the slide K, and consequently cause the type-wheel to make repeated impressions on the paper fora single depression of a key unless the key is quickly released.
- I provide means for locking the slide K in its elevated position until the depressed key is released, thereby keeping the cam k of the slide clear of the cam k of the driving-shaft and preventing the cams from raising the slide more than once for a single depression of a key.
- the preferred device (illustrated in the drawings) consists of ahorizontally-sliding bolt L,' adapted to interlock with the upper disk of the slide K, as shown in Fig. 3. This bolt is guided in a pair of arms or hangers Z, depending from a horizontal carriage L, which slides in guideways Z secured to the under side of the top plateA, as shown in Figs.
- This disk is be vel.ed at its edge, as shown, and the head of the spring-bolt has a correspondingly-beveled nose over which the beveled edge of said disk rides freely during the upward movement of the slide K, allowing the disk to 'rise above the bolt, while the upper side of the bolt is abrupt, so as to check the descent of the slide until the bolt is withdrawn by the release of the-depressed key. It will thus be seen that whenever a key is depressed, the bolt L is automatically thrust into thepath of the slide and caused to lock the latter in its raised position, where its cam k is out of reach of the cam 7c of the drivingshaft.
- the cam of the driving-shaft can therefore act but once upon the cam of the slide fo r a single depression of the key, thus i avoiding repeated impressions ofthe corresponding character unless the operator releases and again depresses the same key.
- in underscoring or rulingthe capacity to make repeated im-' pressions by the single depression of a key is a desirable feature, and in order to permit the operator to do this the stem of the lockingbolt L is extended forwardly within convenient reach of the operator and provided with a ring or knob Z whereby the operator may withdraw the bolt by hand for allowing the H slide K to play freely up and down under the action of the cams WP, and thereby vibrate the type-wheel so long as the key down.

Be it known that I, HAROLD JARVIS, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification. I
This invention relates generally to typewritingmachines in which the impression of the type upon the paper is effected automatlcally by power instead of by the physical driving and driven shafts and the slide for,
vibratlng the type wheel or carrier, the slide being in its depressed position. Flg. 3 is a view similar to Fig. 2, showing said slide locked in its elevated position to prevent double or repeated printing of the typewheel for a singledepression of a key. Fig. 4 is a horizontal section in line 4 4, Fig. 2. Figs. 5 and 6 are detached face views vof the cams which vibrate the type-wheel. Fig. 7 is a horizontal section of the machine in line 7 7, Fig. 1.
Fig.8 is a'fragmentary horizontal section in line 8.- 8, Fig. 1, showing the carriage-feed mechanis m.,. Fig. 9 is a cross-section in line 9 9, Fig. l. vation of the s rift-keys of the type-wheel and their stops. Fig. .11 is a rear elevation of the upper portion of the machine, partly in sec-.
tron. .Fig. 12 is an enlarged cross-section in line 12 12, Fig. 1.
Similar letters of reference indicate corresponding partsthroughout .the several Views.
A indicates the horizontal base-frame of the machine, which may be of any suitable construction, and A is an elevated top late or frame suitably supported on said aseframe and carrying the paper-carriage and other parts of the machine;
B is the main driving-shaft of the machine, arranged vertically in the lower rear portion Fig. 2 is a;
Fi 10 is a fragmentary side elethereof and continuouslyrotated in the use of Y the machine from any available source of power. prefer to employ for this purpose an electric motor Bofany ordinary construc-- .tion, in which case the shaft B carries the ar-.
mature of the motor. Above this shaft and arranged in axial alinement therewith isa second or driven shaft C, which is journaled I in a standard. or bearing 0, mounted on the top late A, the. shaft being held against vertica movement in its bearing by any suitable means. The upper shaft C is driven from the main shaft B by a clutch or connection which is so constructed as to transmit the motionofthe main shaft to the shaft C under ordinary conditions, but permits the motion of the latter shaft to be arrested while the main shaft I continues to rotate. The
2, and 3, consists of a friction-clutch com,-
tongues d, the free lower en s of .whic embrace the edge of an annular head (1 secured. a i h to the upper end of the driving-shaft B,-.the friction etween this head and the springton ues being sufficient to compel the driven sha t C-to turn with the driving-shaft B, ex-- A cept when the driven shaft is positively held?

referred trans-. 5 mitting device shown in the rawings, Figs. 1 -1:. 7s prising a head d, rigidly secured to the driven I shaft C and provided with de ending s' ring.-
bearing one or more rows of'characters on-its periphery in a manner common to this class of type-writing machines and adapted to vibrate toward and from the usual platen F for imprinting its characters on the paper. This type-wheel is mounted on a shaft 2, so asto turn therewith, and this shaft is connected with the upper end of the driven shaft C by a universal joint 6 of any suitable construction, which compels the type-wheel shaft to turn with said shaft and yet permits the type wheel to swing freely toward and from the platen. I The type-wheel shaft is journaled at its ends in an upright vibratory yoke or frame E, provided at its base with laterallyextending arms or trunnions e, which are j ournal'ed in standards e rising from the top plate A, as shown in Fig. 11. Thetype wheel is swung away from the platen by a spring e ,'resting upon a bracket 6 of one of the standards 6 and bearing at its up er end against a shoulder of a rod 6 which atter is pivoted at its upper end to a forwardly-extending arm of the adjacent trunnion, as
shown in Figs. 1 and 11.
siaees shown in Figs. 1 and 11. The rod e is guided stopin h is raised into the path of the con in an opening in the bracket e The typewheel, while compelled to turn with its shaft, is free to slide axially thereon for bringing one or another of its rows of characters in the proper printing position. The connection between the type-wheel and its shaft (illussleeve g, secured to the type-wheel shaft and provided with upwardly-projecting guideins g, which pass loosely through openings formed in the bottom of the wheel and in a smooth disk or washer g interposed between the wheel and the flange of said sleeve, as The type-wheel is yieldingly held in its depressed position, in which its upper row of small letters is presented to the platen, by a spring giwhich surrounds the type-wheel shaft between the top of the wheel and the upper arm of the vibratory frame E. i
The continuously-rotating type-wheel is arrested at different predetermined points in. its rotation preparatory to imprinting the desired characters by an annular series of movabl'e stops h, which are individually projected by means of the key-levers I into the path of a radial stop-arm h, rigidly connected with the driven shaft 0, preferably by being secured to the fixed head d of said shaft, as shown in Fig. 1. The stops it consist of vertical pins arranged in an annular row concentrical y with the shaft C and sliding in guideopenings formed in a fixed horizontal ring H, which is. supported by standards 7L secured to the upper plate of the base-frame A. There are as many of these stop-pins as there are key-levers I, and the lower end of each pin is connected with the rear end of one of the keylevers, preferably by providing the flattened lower ends of the pins with vertical slots and assing the hook-shaped rear ends of the keyevers loosely through said slots. The keylevers are fulcrumed between their ends upon a common pivotrod '5, supported at its ends in bearings on the base-frame A, and the rear arms of the levers are guided in the slots of an upright comb t, secured to the top of the base-frame. During the use of the machine the stop-arm 71 sweeps over th'e'upper edge of the guide-ring H, and the stop-pins h are normally retracted out of the path of said armby the weight of the inner armsof the key-levers, which arms are preferably longer than their front arms to which the keys i 'are secured, as shown. If desired, the stoppins may be further held in their depressed position by springs i acting to depress a pair of vertically-swinging arms 1', pivoted to the base-frame A and carrying a universal bar 2, Figs. 1 and 7. This bar extends'across the v upper sides of the key-levers behind the pivotrod i, and thus tends constantly to depress the rear arms of said levers and the stop-pins. Upon depressing a key-lever the companion connected therewith preparatory to the forward or printing stroke of the wheel. The
I various stop-pins h are so arranged that u on trated in the drawings) consists of a flanged depressing the key representing the desired character the type-wheel will be stopped in its rotation the instant that its corresponding character arrives opposite the printing-point.
It will now be understood that when no key is depressed the driven shaft C together with the stop-arm h and the type-wheel are constantly rotated in the same direction at a comparatively high speed, say about five hundred revolutions per minute, and that under these conditions no slippage takes place between the members (1 d of the frictionclutch. When, however, the driven shaft C is arrested by the elevation of one of the stoppins h,the lower clutch member d carried by the driving-shaft, slips onthe spring-tongues (1 until the depressed key is released and the .raised stop-pin is retracted out of the path of the stop-arm, when the friction-clutch again compels the driven shaft C to turn with the driving-shaft, the two shafts turning together until the stop-arm h encounters another projected stop-pin, and so on as long as the keys are operated.
The forward or printing stroke of the typewheel is efiected by the following mechanism: J is a vertically-movable rod sliding in an opening in the standard 0 and provided at its upper end with a rigid laterally-extending arm j. The upward movement of this arm is transmitted to the vibratory type-wheel frame E! preferably by means of a comparatively stiff bow-spring j, the upper end of which is secured to the lower .corner of said frame, while its'lower end rests loosely on the arm j; The rod J extends below the top plate A and is adapted to be elevated by a vertically-reciprocating member or slide K, composed of heads or disks 76, having central openings for the passage of the shaft 0, and vertical rods 7c, connecting said disks on opposite sides of said shaft and passing loosely through openings in the fixed head (1, as shown in Figs. 1, 2, 3, and 4. On the opposingfaces of the lower clutch-head d and the lower disk of the slide K are secured spiral cams k k, which bear against each other. Whenever the shaft 0 is arrested by its arm h encountering one of the stop-pins h, the continued rotation of the driving-shaft B causes the cam k connected therewith, to act upon and lift the cam k thereby'elevating the slide K, which latter in turn lifts the corresponding end of the upper cam- 7r theslide K is depressed to its former position by a return spring is, which surrounds the driven shaft 0 between the fixed head d and the lower diskof the slide, and when this occurs the type-wheel frame is swung away from the platen by its return-spring. At the same time the rod J is lowered to its former position by the" return movement of said frame. The purpose of the bow-spring C is to causethe type-wheel to strike the platen with an elastic or yielding blow and to'avoid the necessity of. accurately adjusting the position of the type-wheel frame relatively to the platen. Owing to the high speed of the driving-shaft B, the cams k k will repeatedly actuate the slide K, and consequently cause the type-wheel to make repeated impressions on the paper fora single depression of a key unless the key is quickly released. To obviate this objection in case the keys should be held down longer than is necessary to produce a single stroke of the type-wheel, I provide means for locking the slide K in its elevated position until the depressed key is released, thereby keeping the cam k of the slide clear of the cam k of the driving-shaft and preventing the cams from raising the slide more than once for a single depression of a key. The preferred device (illustrated in the drawings) consists of ahorizontally-sliding bolt L,' adapted to interlock with the upper disk of the slide K, as shown in Fig. 3. This bolt is guided in a pair of arms or hangers Z, depending from a horizontal carriage L, which slides in guideways Z secured to the under side of the top plateA, as shown in Figs. 1, 3, and 9. A spring 1 applied to this bolt between its head and the rear arm of its bow-lever L in the proper direction to shift the carriage L rearwardly and 'move the spring-bolt Linto the path of the upper head or disk of the vertically-movable slide K.
This disk is be vel.ed at its edge, as shown, and the head of the spring-bolt has a correspondingly-beveled nose over which the beveled edge of said disk rides freely during the upward movement of the slide K, allowing the disk to 'rise above the bolt, while the upper side of the bolt is abrupt, so as to check the descent of the slide until the bolt is withdrawn by the release of the-depressed key. It will thus be seen that whenever a key is depressed, the bolt L is automatically thrust into thepath of the slide and caused to lock the latter in its raised position, where its cam k is out of reach of the cam 7c of the drivingshaft. The cam of the driving-shaft can therefore act but once upon the cam of the slide fo r a single depression of the key, thus i avoiding repeated impressions ofthe corresponding character unless the operator releases and again depresses the same key. In some casesfor instance, in underscoring or rulingthe capacity to make repeated im-' pressions by the single depression of a key is a desirable feature, and in order to permit the operator to do this the stem of the lockingbolt L is extended forwardly within convenient reach of the operator and provided with a ring or knob Z whereby the operator may withdraw the bolt by hand for allowing the H slide K to play freely up and down under the action of the cams WP, and thereby vibrate the type-wheel so long as the key down.
The type-wheelshown in the drawings has is held three rows of characters, and in its normal lowermost position the upper row represent- 1n printing-point of the laten. The wheelis moved axially for rinting characters in its intermediate and ower rows by a pair of shift-keys M M. The levers m m of these keys are fulcrumed on the pivot-rod i, and
5 the small letters stands opposite the the rear arm of the leverm acts upon the a most row of characters into printing position.
The lever'm of the other shift-key M is provided at its rear end with a laterally-extending in m, which engages under the rear arm of t e key-lever m, so that upon depressing the key M it raises the type-wheel'through the medium of the last-named key-lever.
under the front arm of the key-lever m 'and so adjusted asto' limit the depression of the key M when the type-wheel is raised to the proper height to bring its middle row of characters into printing position.
N indicates the paper-carriage, which runs u on transverse tracks "rt, mounted on'the top p ate A. The carriage maybe of any suitable construction, that shown in the drawings being provided witlf ball-bearings n and retained upon its tracks by rollers n jourstop m similar to the stop m is arranged Under the front mo imit IIC its
naledon the carriage and running against the outer flanges of the tracks. The usual springdrum N may be employed for advancing the carriage. capement mechanism may be employed.
The feed mechanism shown 'in the drawings Any [suitable carriage feed or es-' is constructed as follows: 0 is a rack secured 1 horizontally to thefront side of the carriage and having ratchet-teeth at its front edge. With these teeth engage a air of detentpawls 0 0, which are carried y a verticallys'winging lever 0 pivoted at 0 to the standard 0. Both of these pawls are, pivoted to swing laterally in one direction under the action of springs 0 0, While their movement is limited in the opposite direction by suitable stops. The movement of the lever 0 causes the two pawls to engage the rack 0 alternately in a manner similar to the well-known escapement-pawls employed on the Remington and similar type writing machines. The rear arm of the lever o is provided with a laterally-extending tail 0, which overlaps the arm of the vertically-sliding rod J, whereby said lever is rocked simultaneously with the forward stroke of the type-wheel. The return stroke of the lever 0 is effected by a spring 0 P is the space-bar, secured to the front ends of a pair of levers p, fulcrumed on the pivot-rod 1'. One 0 these leverssay the right-hand one, pis provided at its rear end wlth a lateral pin p which extends beneath one of the key-levers I, so that upon depressing the space-bar said key-lever is caused to project the corresponding stop-pin it into the path of the rotary stop-arm, thereby causing the rock-lever o of the carriage-escapement to be actuated through the medium of the cams k k", slide K,- and rod J in the same manner as when a key is depressed and allowing the carriage to advance a step. As the impression-stroke of the type-wheel is also effected by the upward movement of the actuating-rod J, it is necessary to provide means for disconnecting the type-wheel frame from this rod in order to prevent the wheel from delivering an impression simultaneously with the depression of the space-bar. I This is accomplished by making the arm laterally movable relatively to the spring j, so that when the arm is swung under the lower end of this spring the upward movement of the arm is imparted to the type-wheel frame, while when the arm is withdrawn from under the spring the latter and the type-wheel frame are unaflected by the upwardmovement of said arm, and only the rock-lever 0 of the carriage-escapement takes partin that movement. The rod J is free to turn in its bearing, and its arm 1' is swung laterally by a transverse shipper-rod q, sliding in a standard g and having upwardly-projecting pins which embrace said arm, as shown in Figs. '1, 8, and 11. This shipper-rod is actuated from the left-hand lever p of the space-bar P by a bellcrank lever g one arm of which connects with the shipper-rod, while its other arm is connected with said lever by a rod 1 In order to insure the engagement of the arm 9' y H with the spring 3', the arm is provided at its leading edge with a laterally-projecting beveled 1i q, as shown in Figs. 1, 8, and 12. The
tail 0 the rock-lever 0 is arranged directly corresponding stop-pin h is raised into the path of the sto -arm h, stopping the rotary type-wheel in t e proper position to bring the corresponding letter or other character optposite the printlng-point, and the instant. a ter this occurs the type-wheel isswungtoward the platen by the upward movement of the slide K and caused to imprint the character on the paper, as hercinbefore described. By the depression of the key I the locking-bolt'is thrust into the path of the slide K, andjust before the slide reaches the end of its upward stroke its beveled u per ed e trips over the beveled nose of said ockingolt,which latter then interlocks with the slide and retains the same in its raised osition, preventing repeated vibrations of the type-wheel and of the esca ement-lever 0 for a sin le depression of t e key. Upon releasing t e key the lockin bolt L is withdrawn, allowing the slide 1% to descend to its initial position and the type-Wheel to be swung backward by the action of the return-springs k and e. At the same time the raised stop-pin h is retracted, allowing the stop-arm h and the shaft 0 to continue their rotary movement untilsaid arm is again arrested by the-depression of the same or another key. When itis desired to rint a character appearing in one of the. two ower rows of the type-wheel, the appropriate shift-key M or M is depressed just before'operating the key representing the desired character, when the type-wheelwill be shifted axially on its shaft to the pro er printing-level through the medium of the. ifting-rod m and arm m as hereinbefore described. During all of the above operations the actuating-arm J remains in engagement with'the spring j of the type-wheel frame E. ever, the space-bar P is depressed, said actuating-arm is swung laterally clear. 'of said spring, as shown by dotted lines in Fig. :8, -al lowing the type-wheel frame to remain. at rest and actuating only the escapem'ent-lever 0 This action takes place whenever the space-bar is operated; but as soon :as this-bar is rel ased the arm j is automatically swung under the spring 7' ready to vibrate the type wheel frame upon the depression of a writing-. key. This return stroke of the arm is effected by the spring-pressed universaf bar i acting uponthe key-lever with whichthe p ained.
When, how-- cost as compare type-writing machines.
' an ordinary type-writing machine.
As the type-wheel and the carriage-feed mechanism are actuated by power, the machine can be operated with ease, the mere weight of the fingers being sufficient to depress the keys, which require but a short stroke or depression to elevate the light stoppins h, and as the shaft from which the typewheel is driven is cor stantly clutched to the continuously-rotating driving-shaft the arrested ty e-wheel is instant y and quickly rotated t e moment a depressed key is released, permitting the machine to be 0 erated at a very high speed.
