Application filed December 12. 1905. Serial No. 291.497.

To all whom it may concern:

Be it known that I, OCTAVE Conn, a citizen of the French Republic, residing at Montlimar, Drome, France, have invented certain new and useful Improvements in Type- Writers, of which the following is a specification.

The principal objects of my invention are to provide a type-writing machine, preferably of the vislble' writing character, improved type-bars, each preferably bearing a plurality of characters, to provide actuating mechanism therefor, to provide an improved carriage adapted to be presented at the proper point to receive the printing stroke-of any character carried by a key, to provide for the proper spacing of characters and words, to provide improved inking means, to provide a machine that is not complicated but which has comparatively great strength.

In the following description and claims and in the accompanyingdrawings I have shown a preferred embodiment of my invention for accomplishing the foregoing and hereinafter indicated objects.

In the drawings .Figure 1 is a plan view of the machine. Fi 2 is a vertical section on the line 2 2 of ig. 1. Fig. 3 is an elevation of the carria e feed mechanism. Fig. 4 is a plan view of the mechanism shown in Fig. 3. Fig. 5 isan elevation of a type-bar. Fig. 6 is an elevation of the type-bar, shown in Fig. 5, and taken at a plane normal to that of Fig. 5. Fig. 7 is anelevation ofa keylever. Fig. 8 is a plan view of a key-lever. Figs. 9, 10 and 11- are respectively front elevation, plan view, and transverse section of a 1 frame for supporting and guiding the typebars. Fig. 12 is a plan view of the lower plate of the frame shown in Figs. 9, 10 and 11. Fig. 13 is a front elevation of the bellcrank frame which returns the inking pad to its normal position. Fig. 14 is a section of the mechanism shown in Fig. 13. Fig. 15 is a lan view of the inking ad.

n the illustrated embo iment of my machine, 16 indicates the base-plate, to whichare removably secured, at each side of its center, type-bar supporting and guiding frames 20, each composed of a top-plate, dependent sides which terminate in attaching feet, and a plate supported by the 7 dependent sides and located below the toplate.

The top and bottom plates 0 the frames 20 are provided, respectively with . alining openings 49, 50 those of the top-plate being f keys are fulcrumed.

preferably circular, and those of the lower plate being preferably rectangular. Each ali'ning pair of openings receives a type-bar composed of a horizontal arm 18,v an outer vertically disposed type-bearingarm 19, and

aninner vertically depending arm 17 which.

is formed with a circular upper portion, a reduced portion 45, forming a neck, and a lower portion 46, preferably rectangular, formed with a helical twist which terminates in a foot 47 adapted to normally rest upon the base 16, thereby supporting the weight of the type-bars. The type-bearing arm 19 carries, in vertical arrangement, a plurality of characters.

When the type-bars are in place in their frames, thecircular upper portion of the arm 17 is positioned in a circular opening 49, the

lower rectangular portion is positioned in a correspondingly shaped opening 50,and the neck 45 is disposed abovev the lower plate 48and is embraced by the forked end 52 of a key-lever 21 having a finger disk 51, and pivoted at 53 on a rod 22 u on which all of the his rod 22 extends across the base-plate 16, and, as shown, is supported in brackets secured thereto.

Along the center line 22 of the machine, brackets, as shown in Figs. 1 and 2, are se-. cured to the base-plate 16. These brackets rotatably support rock-shafts 3536, provided res ectively at their front ends with finger-dis s 60, 61 and formed at their inner ends with crank arms as shown in Figs. 1 and ;2. The crank arm of rock-shaft .35, when the latter is at rest, occupies an approximately vertical position, as shown in Fig; 2, and in this position .it forms a support for a bar 39, and the crank-arm oi' the rock-shaft 35 normally occupies a position approaching a horizontal and resting below the plane of rod 39, on a portion of base-plate 16. The

rod 39 extends longitudinally of the machineand is provided at its ends with arms by means of which it is pivotally connected to a rod 37 ,su ported in brackets38 secured to the baseate 16.- The rod 37 together with the rod 39 and the arms connecting the latter to the former, form a rectangular frame which supports a U-shaped carriage 24', the rod 37 passing throughopenings in the opposite sides of the carriage, and forming-a pivotal axis about which the carriage can be oscillated. The rod 37, together with the rod 39, upon which the front ends of the sides of the carriage rests, form a support on which the carriage can slide laterally. It will thus ends of the sides'of the carriage 24. Aplaten 26 is rotatably supported by the carriage 24, and rolling in frictional contact with the platen is a aper-feed roll 27 rotatably supported in t e outer. ends of arms which are .whic

pivotally connected at their inner ends to the sides of the carriage 24. An outer end of the shaft of roll 27 is provided with a rowel 55, by means of which the line spacing of the writing can.be manually accomplished. The rear side of the carriage 24, along the upper edge thereof, is formed with ratchet teeth 25. These are engaged by a awl 28, pivoted to the vertical arm of a'bell crank lever 29 fulcrumed, at 30, to a support 31, secured to the base 16. The horizontally disposed arm, of the bell-crank lever 29 rests upon one end of a lever 43 ivoted at 44 to a bracket and stop 62, secure to the base-plate 16. The other end. of lever 43 projects forwardly as shown in Figs. 1 and 2.

A bar 42 tends to'form a U-shaped frame and is pivoted at the extremities of the legs thereof, upon pins 40 carried by brackets 41 which are secured to the base-iplate 16. The

longitudinal ortion of the ame 42 rests upon all of t e key-levers 21 intermediate their fulcrums and their ends engaging the type-bars, and this portion of the frame rests also upon the inner. end of a lever 23, ful= crume intermediate its ends on the rod 22, and provided with a finger disk 56, and finally-the longitudinal portion of the frame 42 rests upon that end of lever 43 opposite to the .end which sup orts the horizontal branch of the bell-era lever 29.

The carriage 24 is provided with an arm 64 which'projects from one side thereof and forms a hand grip for returning the carriage to its initial position.

In order that the paper, bein printed, shall be properly guided and he (1 to the laten,26, clips 54, carried by a rod supported a y the sides of the carriage, embrace the, lower surface of the platen 26.

An inking pad, comprising a plate 34, and

' inking wings, rigidly'connected to, located above, and angularly disposed to the plate 34, is (pivotally mounted on a rod 33 secured to an plate 16. The lower plate 34 of the inkingpad contacts with the u per bar of a be crank frame 57 fcompose of two open rectangular frames, disposed at an angle to each other, the inner member of each rectangle bein formed by a bar, common to both, forms-the pivot for the bell crank frame, and which is fulcrumed in brackets 58. One portion of the bell-crank frame 57 is on its projecting vertically from the baseapproximately vertical, and its upper bar, as before stated, contacts with, and is held against the plate 34 by an arm 59 which projects forward from the hinged frame 42 and presses downwardly u on the other rectanglplar-arm of the bel -crank frame 57. I

T e type-bars as shown, are grouped on opposite sides of the center of the machine, and the vertical portions 17 of all of the type-bars being of substantially the same length, the horizontal ortions 18 of all'the bars occupy substantia ly the same horizon tal plane. These horizontal portions however difl"er in length, the length increasing as the distance of the bars from the center of the machine increases so that, all the bars when operated swing to the same printing point.

The operation of my machine is as follows:

If it be desired to print a small letter, the carriage is permitted to remain in its normal position, *shown in Fig. 2, in which position ,it is supported by the crank-end of rockshaft 36. With the carriage in this position the disk 51 of character key 21 is depressed thereby rotating the forked end of 1ts key u wardly, carrying therewith its type-bar,

w 'ch is thus raised vertically until its character bearing arm 19 is above theplane of thehorizontal ortions 18 of the other type-bars, and as the type-bar is carried still further upward, its helical portion 46 is carried into engagement with the walls of its rectangular slot 50, which bearing upon the helical lportion, causes the type-bar to turn type-bearing arm 19,-with'its inked characters into forcible contact with the sheet on the platen to imprint a small character thereon, As the inner end of the key-lever 21 moved upwardly in the manner explained, it carried with it the hinged bar 42, resting g 17 as a pivot, thus bringing the thereon, and as-the bar 42 had been resting on the front end of lever 43, keeping its rear end elevated, it will be seen that the rear end of lever 43, as a consequence'of the upward movement of the bar 42, fell, thereby causing the bell-crank lever 29 to turn on its fulcrum, thereby drawing the pawl 28 towards the right of the machine, over the teeth 25 of the carriage. If now the pressure on finger-disk 51 be discontinued, the keylever 21 will return to its normal position carrying the type-bar downwardly through its slots 49 and 50, the latter acting now to swing the type-bar back to its normal position. As the key-lever 21 returned to its normal position, the hinged bar 42restin on the inner section thereof descende therewith, and again ressed downwardly upon the inner end. ofever 43 elevfating its other end, which in turn elevated the end of the arm of the bell-crank lever 29 resting thereon. This results in swinging the bell-- crank lever about its axis, causing the pawl 2'8 to engage a tooth 25 of the carriage which thereby iscarried-one. space to the left, and into a position readyto receive the next character imprint, properly spaced from the precedin one. v

' Thein ing of the characters .prior to their impression upon the sheet carried by the platen, was accomplished in the following manner: As the'type-bar swung to its printin'gposition, from. the position shown in Fig. 1, the characters carried bythe arm 19 struck the inked surface of a wing 32, being thus properly inked, and as the type bar continued to turn, its character-bearing arm pushed the wingv 32 before it, turning the inking pad around its'axi's 33 until the wing was out of the path of the "type-bearing arm which thereafter" continued its travel to the impression point. As theinking pad was turned on it's pivot, the bell-crank frame 57, the upper bar of which was held against the frame 34, was, by the latter, turned in its bearings 58, this rotation of the bell-crank Y frame being possible as the arm 59, which held itstationary, had been raised by the-bar 42 when the latter was elevated. by the depressing of a key-lever 21. When the pressure hadbeen removed from the key-lever, the consequent downward movement of the bar 42 causedits arm 59 to press on the lower arm of the bell-crank-frarne 57, whose, upper bar was thereby pressed against the plate 34 resulting in the return of the inking pad to its normal position. p t

If it be desired to print, a 'capitala letter, the position of which is at the top of the character bearing arm 19, the finger disk 60 of rock-shaft 35 is depressed, resulting in the turning ofpthat shaft whose crank arm is thereby turnedupwardly engaging and liftingupwardly'the bar 139 which swings thecarriage 24 upwardly ahout'itsjaxis 37'and thus bring's the platen into a sufficiently elevated position to receive the printing impression of acapitalletter, which is. se cured by. striking the proper disk '51, the

carriage being 'held eleva'ted until the'im j zpression has been made. Pressure'upon the disks 60 and 51 is now ditcontinued and'the parts returned to the normal position; 1

If it be desired to'print a numeral or'a' punctuation mark, the position of whichl is at the bottom of: the characte'rarm' 19, the

disk 61. of rock-shaft36 is depressed, thereby turning the rock-shaft and lowering "its crank, which normally supports" the carriage I in "the position shown in Fig. 2, until it strikes the stop 62, which, stopping the further.

downward movement of the crank-arm,

thereby holds the carriage with its platen in proper position, to receive the printing impressionof a'numeral or punctuation' mark, which' can be made by striking the proper disk 51 while the carriage remains in its lowered position. If pressure be now reits travel'gto the left, it can be quickly re v turned to.its initial position by grasping the arm 64, turning the carriage upwardly around its axis 37 thereby swingingits rack downwardly out of engagement with the pawl'28, and then pulling the carriage to wards the right, after which the arm 64 is released and the carriage swings downwardly about its axis 37 into its normal position.

It will be observed that the construction of my machine rendersthe writing thereof jrisihis, a decided advantage, and the inking;

mechanism presents a sure and positive meansfor accomplishing that object, while the machine as a whole is exceedingly simple, and its component parts are so designed that they form a very strong machine.
