7 Application filed June 11, 1900. Serial No. 19,889.

To all whom it may concern:

'Be it known that I, Enwm E. BARNEY, of lrroton, in the county of Tompkins, in the State of New York, have invented new and useful improvements in 'llype-Writing Machines, of which the following, taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

My invention relates to improvements in typcwriting machines and particularly to the class set. forth in myPatent No. 594,978 on key-lever center-strike machines in which the writing is at all times visible, and the platen and type-bar support are movable simultaneously towards and away from each other for printing upper and lower case characters as may be desired.

The object of this invention is to render .such machine more practical in use and cilicient in operation by embodying therein the following novel mechanisms viz:1st, an escapement mechanism; 2nd, means for releasing the esca-pemcnt mechanism; 3rd, differential leverage connections between the key levers and the cscapement mechanism;

4th, universal bar mechanism; 5th, adjustable margin stop mechanism 6th, ad ustable )a )(I holdin means and a su ort for the same and various other novel elements and combmatnms as hereinafter fully described and pointed out in the claims.

In describing this invention, reference is had tothe accompanying drawings forming a part of this specification, in which like characters indicate corresponding parts in all the views. A

Figure .1 is a top plan view, partly broken away, of a typewriter embodying various elements of my invention, portions thereof being removed for disclosing the underlying mechanism. Fig. 2 1s a rear elevation of a portion of a typewriter, showing particularly theescapement and release Figs. 3 and 4 are sideclevations, partly in section, of the detacl'ied mechanism for shifting the platen and pe-lia r' support, and the locking memberg-for locking said shifting means in one of its adjustedpositions, the shifting means being shown in its normal position in Fig.

Figs. -5' and '6* are side'elevations', partly in section, showing particularly the connections between the key-levers and the escapement mechanism and type-bars, the movable member of the escapement mechanism and one of the type bars being shown in their normal positions in Fig. 5, and in their operative positions in Fig. -6-, the release mechanism for the escapo'ment also being shown in Fig. 5. Fig. -7 is an isometric view of one of the detached universal bars seen in Figs. -1-, 3, and 4. Fig. 8- is an enlarged inner face view of portions of the detached escapement mechanism. Figs. 9-

and 10 are sectional views taken, respectively, on lines 9-9 and -1()10, Fig. -8-. Fig. --11 is an enlarged side elevation, partly in section, of the escapement 'and release mechanisms, the adjacent portions of the frame and car-' riage and the left marginal stop mechanism; the stop-dog on the carriage being shown in full lines as forced to its inoperative position. Fig. 12 is an elevation of portions of the mechanism seen in Fig. 11 illustrating more particularly the left marginal stop mechanism; the platen and portions of the carriage being shown by dotted lines in their shifted positions, and the stop-dog on the carriage being shown in full lines. Fig. 13 is an isometric View of the adjustable stop-bar and the pawl carried thereby. Fig. 14 is a face view of the stop-bar seen in Fig. 13, showing the raduations thereon. larged elevation of one of the detached type bars and one of thesupporting fins therefor. Fig. 16 is a similar view to Fig. 15-, partly broken away and showing the bearing for the type-bar. Fig. 17- is an elevation of the type-bar seen in Fig.16. Fig. 18 is a sectional View taken on line 18'18, Fig. 15. Fig. ,19 is an isometric view of the detached bearing for one of the type-bars. I igs. 20 and 21 are isometric views of the pa er holding band and the sup ort therefor. Fig. 22 is an enlarged detai fragmentary perspective view showing the connection between the universal bars and an actuating link. Fig. 23 is a Flg. 24 is a fragmentary plan view of'the construction shown in Figs. 22 and 23. Fig. 25 is a detail perspective view of one of the actuating links between the universal bars and the esca ement mechanism. Fig. 26 is a detail si e elevation showing a key lever and one of Fig. --15 is an en .the universal bars which p ooperate therewith.

A represents a suitable' frame', provided with upright standards a, and 'b and a transverse bar c. B. O. D and E indicate the several rows of key-levers for operating type-bars 'F; and G is a letter-space key-lever all of which parts are constructed and arranged to erform their var1- ous functions in the sirnp est and most efficient manner.

The shifting mechanism, Figs. 1, 2, 3 and 4, serves the urpose of simultaneously moving the quad away from each other for rinting lower and upper case characters. s shown in Figs. -3- and 4- this shifting mechanism consists of a rock-shaft 1 provided with arms 2+ and 3 one of which 2 is pivotally connected to a quadrant or typear support 4- and the other arm 3 is secured to asuitable track 5 for su portingan impression-platen .6. T e

platen 6 is mounted on a suitable car r.

riage -7 provided with one. or. more rollers 8 resting upon and movable alon the having its intermediate portion provided with a de ending arm 21 which istrack 5.' One of the arms as the ower ,arm -3 is provided with an extension 9 movablebetween shoulders 10, and 1 1- which. referably consist of adjustable screws for uniting the movement of the arms '2, 3 and consequently limit the shifting movement of the quadrant 4 v and platen 6.

' 12 represents a toggle-joint having one arm pivotally connected at 13 to the frame A and its other arm pivotally connected at 14: to the lower arm 3 of the rock-shaft 1. The adjacent ends or knuckle of the toggle-joint 12 are connected by a suitable link -15 to one end of a key-lever 16 having its intermediate portion ivoted at 17, to the frame A and pre erably to the transverse bar c. A sultable spring -18 is connected to the link 15' and frame A. for retracting and holding the shifting mechanism in its normal position.

Although the above described shifting mechanism is particularly simple and efficient in operation it will be understood that so far as the features of invention herein claimed are concerned, other forms of case shifting mechanism may be used.

The lockin means for the shifting mechanism, for ho ding the quadrant and laten in such relation that the upper case 0 aracters may be used continuously, preferably consists of-a lock-lever 19 ivoted at 20 to the frame A, or other ed support, and

formed wit an engaging shoulder 22 for engaging a shoulder 23 provided on the upper arm of the key-lever -16. The

rant and platen toward and key-lever 16 and the lock-lever 19 are so relatively arranged that when the same are rocked on their pivots 17, and

desired to print upper case characters c0ntin-'uously the free end of the lock-lever--19. is elevated, the arm 2 1 bears against the shoulder 23 thereby rocking the shiftlever .'16- and shifting the quadrant 4- and laten 6.

en the quadrant and platen have been shifted to the desired position by the elevation of the lever 19 the shoulders 22 and 23 moving in intersecting arcs automatically interlock with each other, at one side of a right line drawn through the pivots 17 and 20, and serve to hold said quadrant and platen in position for printing upper case characters. By depressing the lock-lever 19 the shoulders 22 and 23 are disengaged from each other whereupon the spring 18 automatically returns the quadrant, platen and shifting mechanism to their normal positions. The case shifting mechanism and locking means therefor, shown and described, are not claimed per se herein but are claimed in a divisional application filed by me on the 13th day of May, 1908 and bearing Serial No. 432,556.

The escapement mechanism for letterspacing consists of a rack 25 provided on the carriage 7, a rev'oluble pinion 26 mounted, on the frame A and meshing with the rack 25, a toothed wheel 27 actuated by the pinion 26-, and

dogs

28 and 29 movable into andout of engagement with the teeth of said wheel, for permitting the carriage to move Any desired means may be employed for moving the carriage endwise and thereby actuating the pinion 26 and'the escapement wheel.27. This means is substantially the same asthat shown and described in my former atent 594,978 a portion of which preferab y consists of a spring actu ated wheel -d provided with a suitable cord, not illustrated, said cord having its intermediate portion secured to the wheel d and its opposite ends secured to the carriage in the mannerdescribed in my former patent above referred to and not necessary to herein further illustrate or describe. The pinion '26 is connected to the wheel 27- in the usual manner by means of a ratchet wheel e secured to the pinion 26, and a pawl-f pivotally connected to the wheel 27 in such man; ner that the carriage 7 may be moved to the right without effecting the movement of said wheel 27 and when moved to the left, by means of the spring actuated wheel d, the wheel 27 is rotated'by the pinion 26, ratchet wheel -e and the pawl f. i

The

dogs

28 and 29 are supported on a suitable oscillatory arm, presently described, are reciprocally movable lengthwise of said arm and are preferably connected to a reciprocally movable plate 30 interposed between said dogs. 0

31 represents a rock-shaft preferably ournaled on the frame A and provided with oscillating

arms

32 and 33 usually fixed to the rock-shaft. One of thearms, as 32-, is provided with a lengthwise guide 34 for receiving and guiding the dog 28 in its reciprocal movement, said dog 28 being provided with a shoulder, as a screw g, movable in a slot '-a formed in one of the walls of the guide 34 for limiting the movement of said dog and holding the same in its operative position. The reciprocally movable plate 30 is also movable along the guide 34; is secured to the dog 28-v and is provided with a a guide rib iengaged with the arm 32 for guiding said plate in its reciprocal movement. The arm 33 is connected bya link or rod 35 to the differential leverage mechanism, previously mentioned, Which, in turn, is actuated by the several type-bar and letter spacing key levers hereinafter described.

The means for reciprocating the

dogs

28 and 29 consists of the release mechanism, previously mentioned, which forces the plate 30 and the dogs -28' and -29, connected thereto, in one direction for disengaging said dogs from the wheel 27-, and a spring 36 for retracting said plate and dogs to their normal position.

The release mechanism, Figs. 2, 5, 8, 9, 10 and 11 consists of an oscillating bail or bar 37 ivotally connected to the carriage, and preferably to the opposite ends of rack 2 5 and having its outer ortion arranged substantially parallel wit said rack and adapted to engage a roller bearing 38, which is suitably connected to the plate 30 by an arm 39. v

The bail or bar -87, Fig. 11 may be oscillated in any desired manner and is preferably provided with an upwardly extending arm 40 having an inwardly inclined cam-face 41 and a lengthwise slot -42.

43- is a rock-shaft mounted on the carriage 7 and provided with oppositely projecting arms 4t and 45 the arm 44 being arranged to engage the cam-face 41 and is provided with a guide shoulder 46 movable in the slot 42 for preventing displacement of said arm with the cam-face 41. i The other arm 45 consists of a suitable hand-piece preferably arranged at one end of the platen 6 and is limited in its movement by any desired form of stop as the adjacent end of the axle of the platen seen in Figs. 5 and 1 1.,

It is evident from the foregoing description that, as the arm 45 is depressed, the arm 44 is elevated and rides upon the camface 41 thereby rocking the bail or bar 37, which engages the roller '38 and 'actuates the plate .30 for forcing the also returned to its normal position by said spring 36 or an additional spring 47, Figs. 1' and .2, secured to said shaft and to the adjacent portion of the carriage.

The differential leverage connections be tween the several key-levers and the escapement mechanism, Figs. 1, 5, 6 and 22 to 26 inclusive, consists of a rock-shaft 48 mounted on the frame -A and provided with

arms

49 and 50, and an oscillatory arm '51- also mounted on the frame A and preferably pivotally connected to the transverse bar c. is provided with a substantially straight engaging face, and the arm -51 is formed with a curved or cam-face engaging the straight face of the arm 49 and connected to the rock-arm 33- by means of the link or rod 35..

The engaging faces of the arms 49 and Y 51- are so relatively arranged that the least power is required for operating the escapement during the initial movement of the operating key-lever, and, were it not for the compensating effect resulting from the momentum of the moving parts during said initial movement of the key-lever, the greater power would be exerted at the end of the operative movement of said key-lever. In or der to effect this easy key-action the portion of the cam-face of the arm 5l is nor-, mally engaged with the portion of the arm -49 nearest the axis of said arm as seen in Fig. 5-, the remaining portion of said cam-face being normally separated from the arm -49. As the arm '-49 is rocked towards the arm 51- the contact point of the engaging faces of said arms varies and gradually increases in distance from the axis of the arm 49 thereby producing a grad-' ually varying leverage connection between the arm 49 and the eseapement mech anism actuated thereby.

Owing to the fact that the initial stroke of the operating key-lever is the most powerful, and that the momentum of the moving parts connected thereto facilitates the completion The arm 49 and that the of the movement of said moving parts, it is evident that the increasing leverage between the engaging faces of said arms 49. and '51. is compensated by such momentum key-lever action is rendered easy and thereby reduces to. a minimum the incidental jar to the machine and operator.

The universal connections, Figs. 1, 5, 6 and 7 between the several rows of key-levers B. C. D. and E and G, and the differential leverage mechanism, preferably consist of a series of bails or bars 52, 53 54 and 55, and links 56 connecting said bars or bails to the arm 50- of the rock-shaft 48. The bars or bails 52, 53 54 and 55 correspond with the several rows of key-levers B. C. D. and E; are usually hinged to the transverse bar c in planes one above the other with their intermediate portions 57 arranged substantially parallel and extended transversely of the key-levers, and their opposite ends provided with depending arms 58 .pivoted at -59 to the transverse bar c-.

The portions 57- of the bars or bails 52, 53 54 and 55 are so relatively arranged with reference to each other and to the key-levers, that the leverage of the key-levers of each row acting upon the corresponding bar or bail is substantially the same, the distance between the fulcrum and the engaging ends of the key-levers of each row being in substantially the same ratio.

' The intermediate portion 57 Figs. 1,7, and 24 of each of the bars or bails is provided;

with a series of separated shoulders 60 forming a series of spaces -61 between said shoulders, the shoulders of one series being arranged out of vertical alinement with the shoulders of the remaining series in order that any one of the key-levers of the several rows B. C. D. and E. may actuate one of the bars or bails without affecting the position of either of the other bars or bails or the remaining key-levers.

The shoulders of the u per bail 52 are preferably alined withtiie key-levers of the upper row B the shoulders of the next lower bail are alined with the key-levers of the next lowerrow C and so on, the shoulders of the lower bar or bail being'alined with the key-levers of the lower row, E. Said shoulders '60- of each of the bars or bails are formed of such width that either of the key-levers of one row may independently operate its corresponding bar or bail without affecting the operation of either of the other bars or bails. The opposite ends of each of the bars or bails are provided with elongated slots 62 for receiving corresponding T- shaped cross heads 56 at the ends of the links 56 previously referred to. I preferably use but a single link for each end of the several bars or bails. The ends of said links adjacentto thebars or bails are referably elongated .vertically are arrange Within the slots -62; and are provided with V- shaped cutouts, as shown in Figs. 5 and 6 or substantially V-shaped cutouts as shown in Figs. 22 and 25, arranged one above the other and registered with the rear walls of the slots -62. The spaces '61 and the slots 62 are formed of sufiicient length to permit any one of the key-levers of the several rows B. C.- D. and E, and the links 56 to be operated without aflectin any of the other key-levers or the bars or bails actuated thereby.

The key-lever G-. for letter-spacing independently of the operation of the typebars F may be connected in any desired manner to the arm 50 of the rock-shaft 48 but is preferably arran ed to engage one of the bars or bails, as t e lower bail 55, and shown by dotted lines Fi 5-. The engaging ends of the bars or bai s 52, 53 54 and 55 and'the links 56- are so relatively arranged that the lower bail is registered with the lower cutout of said links; the next higher bail is connected to the next hi her cutout, and so on,-in like manner as said bails are engaged by the key-levers of the several rows B, C, D, and E. It is thus apparent that the leverage between said key-. levers and the links 56 is substantially uniform, and that this feature, taken in con nection with the differential leverage mechanism previousl described, renders the ac- .tion of the keyevers exceedingly easy and noiseless. Any suitable means as springs 63 maybe provided for retracting and holding the bars or bails 52, 53 54 and 55 to their normal or inoperative positions.

" The left marginal stop-mechanism, Figs. 1'1,'12"and 13 and 14, reviously referredto, consists of an adjusta 1e bar 64, a movable pawl 65 mounted on the bar 64 and a movable stop-dog 66 mounted on the carriage ,7-. The bar 64- is preferably mounted on the frame A; is move able in a plane substantially parallel to the endwise movement of the carr1age'-"-,7 in'a suitable guide or guides 67 and is provided with a series of teeth -683 movable into and out of engagement with a fixed shoulder 6 9- on the guide 67. A suitable spring .70 servesto hold said teeth in engagement with the shoulder -69 when the bar is adjusted to the dewhereby the opposite end ofthe dog 66- is forced out of alinement with the I awl 65 when said arm is actuated for re easing the escape mechanism.

When the shift-lever 16 is operated for 1 shifting the platen and its carrier frame, the

' pawl pivot 74 is also shifted and the stop dog 66 is thereby forced out of alinement with the pawl as seen in Fig. 12 it being understood that the release lever 45 and escapement mechanism may remain in its normal position during such operation of the shift-lever.

The bar 64 is provided with suitable graduations -76. movable into registration with a fixed point as the end face of the guide 67 for indicating the desired width of left marginal space on the sheet to be printed. When desired to print in the marginal space above referred to, it is simply necessary to de ress the arm 45 where u on the sto 0g 66 is forced out of a inement wit 1 the engaging end of the pawl -65 and the carriage is free tobe moved, carrying the dog 66 beyond or to the right of the pawl 6.5--. The dog -66 and escapement mechanism is then permitted to return to its normal position; the printing is continued and the dog 66- contacts with a cam-face formed on the 65 whereby said pawl is automatically forced inwardly against the action of the spring 72 and the printing may be continued Without interruption.

Upon referring to Figs. 3, 4, 20 and 21 it will be seen that spring pa er guides or fingers 77 are supported in ace by a tubular guide or support 79 whic 1 extends longitudinally of the platen throughout or substan tially throughout its length and is connected to, or formed as a part of, a member 78 which is supported in any suitable manner by the carriage 7. Each pa er finger or guide 77 is provided with a cyindrical member 81 (Fig. 20) which has a diameter corresponding substantially to the diameter of the bore of the tubular guide 79 in which it is seated. Said tubular guide has a narrow longitudinal slot 80 cut through its wall and extending throughout the length thereof, and through which the paper fingers 77 project; the fingers bearing against the platen. The construction is such that the paper fingers may be. adjusted along the tubular guide or support 79 to any desired position and the tension of the spring fingers maintained against theplaten will cause the fingers to bear with sufficient ressure against the wall of the-slot 80 to hold them in their adjusted positions.

ened peripheral bearing face 85- for receiving a fin 86-, which may be secured to the quadrant in any manner desired. These type-bars are bifurcated at their lower ends for receiving the fins -86 and as seen in the drawings these fins are formed of slightly less width than the distance between the inner walls of the bifurcated extremities of the type-bar and are each provided with an a erture or bearing for receiving the was er-bearing 83,. The Washer-bearin 83 is formed of slightly greater width t ian the thickness of the fin and is substantially the same width as the distance between said bifurcated ends of the type-bars. is passed through apertures in the type-bars alined with the aperture 84 of the washer .83 and is upset or riveted at its outer ends for firmly securing said bifurcated ends of the type-bars to the washer. It is thus apparent that the washer and type-bar are substantially integral and that by hardening the walls of the aperture of the fin 86- which bears upon the hardened periphery of the washer 83 the bearings for the typebars are substantially indestructible and maintaina perfect and uniform alineincnt.

From the foregoing description it will be seen that the flexing connection comprising the pivotally connected links 12 of the shift mechanism constitutetoggle links arranged end-to-end and that said hnks in the normal position of the parts shown in Fig. 1 are approximately in a straight line position, and that the toggle is flexed or broken from this position to shift the shiftable member so that the links constitute what may be termed a reverse to gle and that the spring 18 acts to counterba ance the weight of the platen or shifted part and to restore the shifting mechanism to normal position. seen that

arms

49 and 51 comprise varying or differential leverage mechansim between the finger key and the escapement devices and between the universal bars and escapement devices and that the parts are so constructed and arranged that the'least power is required for operating the letter spacing or feed devices during the initial portion ofthe movement of each finger key.

, The operationof the machine will now be readily understood upon reference to the foregoing description and the accompanying draWin s and it will be noted that the various A rivet or other securing means 4 It will also be novel e ements' herein shown and described may be somewhat varied without departing from the spirit of this invention.

The type bar bearing construction herein set forth forms the subject-matter of a divisional application filed January 27th, 1902.
