To all whom it may concern:

Be it known that L EDWIN E. BARNEY, citizen of the UnitedStates, and resident of Syracuse. in the county of ()i'iondaga and State of New York, have invented certain new" and useful Improvements in Type- W'riting Machines, of which the following is a specificatiiim. I

My invention relates to typewriting ma-' chines and more particularly to variable car riage feed mechanism.

The main object of my im'ention is to provide simple and efficient, carriage feed mechanism which may be regulated at will to afford one or another character of letter spacing as may be desired.

A further object of my invention is to provide a variable carriage feed mechanism of the character specified above in which the change from one width of letter space feed to another may be effected without altering the action of the carriage feed devices proper or changing them in any manner.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction. arrangements of parts and combinations of devices to be described in the following specification and sct forth in th appended claims.

in thc accompauying drawings wln-rcin' like I't l'crcncc characters indicate corrcspondin parts in the various views. Figure 1 is a central. vertical. fore and aft sectional, view of a ty 'iewriting machine embodying my invention; only so much of the machine being shown as is necessary to illustrate my invent ion. Fig. 2 is a plan view of the same. Fig. I is a fragmentary rear eleva tion of the same. the view showing the upper portion only ot a typewritingg machine. Fig. 4 is a fragmentary face View of a sheet showing specimens of the work produced on the. machine under dillerent conditions. Fig". 5 is an cnlargml detail rear elevation with pa rts in section and parts broken away of the transmitting means between the carriage and the cscapcmcnt mechanism and the means for adj listing sa id transmitting means; the parts in this view being shown adjusted to all'ord ordinary letter spacing as indicated in the spccin'ien a in Fi 4. Fig. 6 is a view that corresponds to Fig. 5 except that the parts are shown adjusted to afford a spacing such as that represented at b in Fig. 4. Fig. 7 is a plan view of the parts represented in 4 fixed to the top plate of the machine, the guide rails being grooved on opposite faces for cooperation with anti-friction balls or rollers 5. These rollers 5 are likewise received in opposite grooved faces of a guide or slide bar 6 which constitutes the rear crossbar of the carriage from which forwardly extending end bars 7 project, the end bars having bearing openings for a shaft 8 which supports a cylindriral. platen 9. The carriage is adapted to travel in the usual manner from side to' side of the machine and is provided with the usual arms 10 which are pivoted to the cz'irriage and carry a feed rack 11. The feed rack cooperates with a. feed pinion 12 formed on the forward end ot' a shaft 13 mounted in a. bearing bracket l-l fixed to the top plate of the machine by screws 15. An esca 'icmcnt wheel 16 is operativcly connected to the shatt 13 by the usual pawl and ratchet. mechanism contained within a drum 17 so that the shaft 13 is free to turn independently of the escapenicnt wheel during the movement of the carriage from left to right, but the cscapement shaft 13 and teed pinion 12 rotate together as the carriage moves to the left under con-. trol of the escapcmcnt. A spring drum 18 is connected to the carriage by a band 19 secured at onc cnd 20 to the drum and at the opposite end to a pin 21 which projects from the carriage to move the carriage in the letter t'ccd direction. Feed dogs'QQ cooperate with the cscapement wheel in the usual manner, the feed dogs being carried by a dog rocker 23 pivoted at 24- to a bracket- 25 secured to the top pl ate of the machine. A. forwardly extending arm 26 projects from the dog rocker and is connected to a depending-link 27 which in turn is connected to a. rearwardly extending arm 28 of a universal bar frame 29, the rock shaft 30 of which is pivoted at its ends in suitable bear site the feed pinion 12.

ings in the base of the machine. The universal bar fraim' earries a universal bar 31. which extends beneath the series of key levers 32 each having a curved contact tread 33 which cotiperates with a fulcrum plate 34 secured to the base of the machine. Restoring springs 35 are connected to the key levers to restore the key levers and parts connected thereto to normal positions. Each key lever is pivotally connected at 30 to a sub-lever 3T slotted at 2-38 to receive a fixed fulcrum rod 39 which extends transversely of the machine beneath the key levers and is secured at its ends to the base of the machine. The upper end of each sublever is cotmected to a pull link it) which in turn pivotally connected at it to a type bar 42. Various type bars are segmentally arranged and adapted tostrike upwardly and rearwardly against the front face of the platen 9. each type bar being pivoted on a hanger 43 supported on a type bar segment 44, adapter to be shifted vertically to change the case msition of the types with reference to the platen.

The construction thus far described is or maybe the same as that employed in the Monarch machine and further detailed description thereof is deemed unnecessary.

From an inspection of If gs. 5. (i, T and 8 it will. be seen that a lever-like arm, carrier or plate 45 is pivoted on a reduced hub or portion it;v (Fig. T) of a pinion T which surrounds the escapement wheel shaft 13 so that the carrier 45 may receive a pivotal movement around the hub 4-6 and around an axis which iscoincident with the axis of the escapement wheel and feed pinion. The pinion 47 is mounted on the shaft- 13 of the escapement wheel at the rear side of the car rier'45 and on the side of thecarrier oppo- A pin 48 connects the pinion 47 with the shaft so that the feed pinion 12, pinion 47 and shaft 13 are fixed to rotate together. The pinion -17 meshes with an idle gear 49 adapted to turn on a shouldered pivot screw 50 received .ina tapped opening in the carrier -t5 and prov1ded with a lock nut 5W.- The gear 49 likewise meshes with a larger gear 51 provided with a sleeve or lmb 52 (Fig. 8) received in a bearing opening in the carrier 45 and extending therethrough. .\gear 53 is connected by a headed screw '54 with the gear 5t; the screw passing through thebearing hub of the gear 51 and taking'in a tapped opening in the gear 53. A pin 55 may be driven into openings formed in the screw 54, sleeve 51 and gear 53, in order to lock these parts to rotate together. The gear 53 is a counterpart of the feed pinion l2 and is situated on the side of the carrier 45 opposite the gear 51 and in the same vert'fial transverse plane as the feed pinion 12, in "der that the-gear 53 may em'iperate with the feed rack 11 of constitutes a guiding means to accurately guide the free end of the carrier 45 in itspivotal movement around the axis of the shalt and to limit the downward movement of the carrler. An arm 59 is pivoted by a shouldered screw (50'on the free end of the arm or lever 45, the lower end of the arm 59 being adapted to bear upon the top plate 3 of the machine. The arm 59 has two faces til and 62, the face 61 hearing against the top plate when the parts are in the position shown in Fig. t5 and'the inclined face 2 bearing against the top plate when the parts are in the position shown in Fig. 5. The downward motion of the free end of the lever 45 is limited by the screw 01' pin 56 engaging the lower end of the slot 57 of the bracket 58. A link or arm (53 is pivoted at one end. as at (it. to the arm 59 and passes freely through an opening in one of the brackets 4 The opposite end of this link or arm (53 is threaded into a. socket (S5 rigidly connected to an arm G8 which projects rearwardly above the top plate from a pin 67. The pin (37 is rigidly connected with the arm (36 and passes downwardly through 11 segmental slot- (18 in the top plate of the machine where it makes pivotal connection with the rear end of a lever (39. The lever69 is pivoted at 70 to the top plate of the machine and extends forwardly beyond. the front edge of the top plate where it is provided with a finger piece or head 71 by which the lever may be manipulated. It will be understood that the link433. socket 65, arm 66 and depending pin 67 constitute a single rigid piece or frame by which the arm 59 and the carrier 45 may be adjusted. The pivotal connection between. the pin 67 and the rear end of the lever ()9 is best shown in Figs. 1 and 3 from which it. will be seen that the pin 67 passes downwardly through an opening in the rear end of the lever arm and nuts 72 amLII-l are tln'eatled'onto the end of the pin ()7 on tfiipositc sides at the arm.

From the foregoing description it will be understood that a swinging movement of the finger piece 71 to the left in Fig. 2 is eti'ective to move the link or arm 3 to the position shown in'Fig. G in order to effect an elevation of the free end of the carrier 45. This movement operative to elevate the. gear 53 to bring about an engagement between the gear 53 and the feed 'ack 11 and a continued upward movement of the gear elevates the feed rack 11 and disengages it from the feed pinion 12 while maintaining engagementv between the rack and the gear 53. The movement of the parts to the positions shown in Fig. (3 IS effective to move the end 61 of the arm 5!) into cooperation with the top plate'so that the carrier 45 and the parts controlled thereby are thus maintained elevated in the positions to which they 'are moved in Fig. 6. The effect of thus disengaging the feed "rack from the ordinary feed pinion l2 and .and transmission of with.the gear wheel engaging it with the gear 53 is to cause the transmission of movement from the carriage to the escapement wheel 16 to be effected through the "cars 47. 49, 51 and 53 instead of directly through the. feed pinion 12, as when the parts are-in the normal position shown in Fig. 5. The effect of bringing this-train of supplemental differential gearinginto effective cooperation with the feed rack ,is to differentiate the extent of letter space feed movcment'to be given the carriage at each actuation of akey. The differential train of gearingin the particularconstruction shown, affords less moven'ient of the carriageat each letter space actuation than when the feed rack is in direct engagement with the feed pinion 12. The effect of changing from one extent of feed to-the other best illustrated in the sample line..of writing indicated at 11 corresponds to that produced when the feed rack is 'lll direct engagement with the feed pinion l2;

whcreas, thc line of writin indicated at corrgeponds to a'line produced when the rack is disengaged from the feed pinion 12 motion is effected through the engagen'ient of the feed rack It will be understood that the character of feed will remain the same as long as the finger piece 71, remains-in one or the other of the two positions to which it may be set.

The invention is useful for a variety of nn'|)o, es, such, for instance, as 'n'oducing by the machine a distinctive effect as indicated at b that will be the equivalent of an italic insertion in the ordinary typewritten matter. and which is now ordinarlly designated by ul-ulerscornv The mechanism is also useful when! an erasure- Is to be made,

' and a new word or words, with one or more letters or words, are to be inserted within the original space, so that corrections may be readily and neatly made. This is made apparent from a comparison of the lines a. and I; in Fig. 4.

It will be understood, of course, that the effect of changing the engagement; between .the feed rack .11 and the gears 12 and 53 is to change the ratio of the operative connections between the escapementwheel and carriage and thus vary the extent: of letter space feed movement without in any manner changing the action of the escapement. mechanism proper or the extent of movemeat thereof. The escapen'ien't devices will operate the. same under all conditions and always have a uniform extent of letter space movement at: each actuation. It will likewise be understood that the means wher by the variation of the extent of letter space feed is produced are separate from the escapemcnt devices andcomprise supplemental, differential or variable gearing. be.- tween the escapement. wheel and carriage; that means are provided for connecting one .or another of the gears controlled by the eseapement wheel with the earring-1 that such means are hand controlled and are operable at will and remain o| )erative'iudefinitely or until a ehange is effected at the will of the operator.

It will be seen that the devices are simple inconstructiou, efficient in use and may be readily changed to any the character. of the letter space feed n'mven'ients of the carriage. I 4

While. I have shown one. form of mechanism embodying my invention it should be understood that various changes may be made without departing from the invention. Thus, for instance, the transmission gears may be varied to afford different styles of differential spacing, it being immaterial for the purpose of my present invention whether the greaterspacing afforded by the parts when they are disposed as shown in Fig. 7 or when they are disposed as shown in Fig. (i. For wide spacing for headings, etc. it might be desirable to change the 'n'oportions of the gears to afford greater width of spacing. than' that atl'ordwhby the usual letter space feed, when the feed rack.
