TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 459,093, dated September 8, 1891.
Application filed April 25, 1891.
T aZZ whom it may concern:
Be it known that I, GEORGE CQBLICKENS- DERFER, a citizen of the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type lVriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 0thto ers skilled in the art to which it appertains to make and use the same.
My invention relates to type-writers, and particularly to that class or type of such machines as have an axiallyanoving type-wheel which is propelled against the platen to impress the type; and it consists in certain improvements in the construction and operation thereof, as will be hereinafter fully set forth, and pointed out in the following claims.
Reference is bad to the accompanying drawings, wherein Figure 1 is a plan View of a typewriting machine embodying my invention. Fig. 2 is a sectional elevation showing papercarriage roller and underscoring,canceling, or like devices, taken on the line 22 in Fig. Fig. 3 is a sectional plan of the same, said parts in both said figures being drawn to an enlarged scale. Fig. at is a diagrammatic side elevation showing key-lever eccentric, ratchet-wheel for the type-wl'leel, stop-pawls for said ratchetwheel, and tumbler-actuating mechanism between the key-lever, rack, and actuating bar or bail for one of said pawls, said parts being shown in their normal position. Fig. 5 is a like view showing said parts in the position assumed by them when the type-wheel is making an impression. Fig. 6 is a side elevation of key-levers and actuating mechanism for variously raising the typewheel on its shaft to bring different fields or rows of letters or characters into action. Fig. 7 is an elevation, partly sectional, on the line 7 in Fig. 1, of the machine. Fig. 8 is a like View on the line 8 in Fig. 1, and shows the feeding mechanism for the paper-carriage in elevation. Fig. 9 is an elevation, partly in section, of the feeding mechanism for said earriage under control of the spacer-bar for spacing between words. Fig. 10 is a plan of typewheel and part of inking device or roller Serial No. 390,488. (No model.)
therefor. Fig. 11 is a cross-section, partly in elevation, of the machine on the line 11 11 in Fig. 1. Fig. 12 is a sectional side elevation of a preferred form of inking device for the type-wheel. Fig. 13 is a perspective view of the standard for supporting said inking device. Fig. 11 is an elevation,looking from the right of Fig. 1,drawn to an enlarged scale, of type-wheel, its shaft, concentric and eccentric ratchet-wheels therefor, limiting-pawls for the eccentric ratchet-wheels, and actuating mechanism for said parts. Fig. 15 is a plan of said concentric ratchet-wheel. Figs. 16 and 17 are like views of the eccentric ratchet-wheel with pawls, type-wheel shaft with pin- 6 5 ion, and segmental racks, showing the same in two different positions. Fig. 18 is a perspective, looking from the front left corner of Fig. 1, showing more plainly the relative position of the segmental racks, eccentric ratchetwheel, stop-pawls for the latter, and tumblers for the actuating mechanism for the racks, one of said pawls, and for propelling the typewheel to the roller or platen. Fig. 19 is a vertically sectional elevation, looking from the rear of Fig. l, partly broken away, of an improved form of paper-carriage. Fig. 20 is a like elevation showing the carriage in connection with its feeding mechanism and the paper-holding rollers in a raised position. 8o Fig. 21 is an elevation, looking from the front of Fig. 1, of the paper-carriage detached from the machine and showing its parts in their normal position; and Fig. 22 is a side elevation of part of the feeding mechanism for the S5 papeucarriage roll detached from the carriage. Fig. 23 is a perspective view of the carriage-actuating ratchet mechanism; Fig. 2-1:, a side elevation, on a larger scale than that shown in Fig. 8, of the paper-carriage 9o actuating shaft, and the pawls for actuating said shaft, and part of the actuating mechanism for said pawls; Fig. 25, a section on line 25 25, Fig. 2i, and on an enlarged scale, of part of the mechanism under control of the 5 spacer-bar for actuating the shaft that moves the paper-carriage; .aud Fig. 26, a perspective of the pawl which is under the control of the type key-levers to actuate the shaftthat moves the papcr-carriage. Io
A represents the frame or housing of the machine, which may be of an oblong or other desired configuration required, having preferably an open front a for the key-board end I) of the key-levers B, and at or near its rear end a a transverse open way or bed a through which slides the paper-carriage C, said frame or housing being suitably connected by transverse bars a a, adj acnt to its front end.
The paper-carriage 0 maybe of any desired construction; but for purposes of my invention I prefer the form shown, which consists of a base 0, composed of two paralled bars 0 7c, united by cross-bars or upright brackets 0 c and from which depends a rack 0 The bars 0 c are preferably round in cross-section and are preferably supported on grooved rollers c 0 suitably mounted in the bed or way a on each side of the same, so that the carriage O can be moved with as little frictional resistance as possible. If desired to prevent any tendency of the carriage C raising from its roller-supports a 0 an additional roller or rollers 0 may be mounted on one or both of the sides of the way a to contact with the upper side of one of the carriage rods or bars 0, as shown more plainly in Fig. 1.
The bracket or standard 0 consists of one piece or a single upright having a vertical slot 0 with open upper end, as more plainly shown in Fig. 19. The bracket or standard 0 consists of a lower fixed part or section 0 to which is hinged an upper part or section 0 as more plainly shown in Fig. 19. The hinged section 0 has an outside tubular hub or projection c ,in which ismounted a tubular sleeve 0, having on its outside end, which projects beyond the outer end of the hub 0 a thumb-wheel e and on its inner end a collar 0 which abuts against the inner side of bracket-section 0 so as to maintain said sleeve a loosely within the tubular hub or projection 0 The collar end 0 of sleeve o is provided with a transverse slot 0, or more than one of these transverse slots 0 may be provided, if desired.
Mounted in sleeve o and in the bottom of the vertical slot 0 of the standard 0 is the main roller D for the carriage 0, its journal end (Z, entering the sleeve o being provided with a transverse pin d for engagement with the transverse slot 0 on the collar end 0 of sleeve 0, so as to connect said collar 0 and sleeve o with said roller D, in order that they may turn or rotate together and for purposes of removing said roller from the carriage, as hereinafter more fully described.
The thumb-wheel is provided, either integrally or otherwise, with a ratchet-wheel 0 which, as shown, preferably overhangs the hub 0 on section 0. Between the ratchetwheel and the standard-section c, and loose on hub 0 is mounted a collar (1 which is provided with a toothed or ratchet cam d (see more plainly Fig. 22) and an arm (1 upon which is pivoted a thumb pawl or lever downwardly-acting spring e (Z the lower end (1 of which is inline with and engages with the ratchet-wheel e on thumb-wheel 0 The collar 61 is maintained in its normal position by a spiral spring 61 one end of which is fastened to collar (1 and the other end to the sleeve 0, or an outer end collar 0 fastened thereto. (See Fi 19.) In the standard-section c and in line with the thumb-wheel ratchet 0 is a downwardly-acting retaining-pawl 0 the action for said pawl being obtained by means of a spring or equivalent device c In line with the collar (Rad jacent to its cam-ratchet d and mounted in the section-bracket 0 is a screw d which engages with one of the teeth of the ratchet-cam d of collar d and limitsits oscillating motion, and in turn the rotary movement of the roller D, to space the lines for the paper on each roller, as hereinafter more particularly described.
Above the roller D is a second roller E, which may be of any suitable construction, as desired; but I prefer to construct and arrange the same for operation as shownthat is to say, it consists of a rod e, having thereon at intervals along its length a number of rubber of other ,elastic collars e e, which hold themselves in position on rod 6 by frictional contact, preferably, and yet admit of being adjusted lengthwise on rod eto suit different widths of paper inserted in the paper-carriage. The free end 6 of rod 6 enters the slot 0 of standard 0 and it may be configured, as desired or as shown, for engagement With a catch 6 pivoted at e in a vertical slot e on standard a and provided with a spring 6, suitably supported in standard 0 which acts to normally keep the catch 0 in engage ment with the end e of rod 6 to form a bear-' ing therefor. The opposite end 6 of rod (2 is mounted, as shown at 6 in a swivel or forked connection e", pivoted at e in a vertical slot 6 in standard-section o and provided with a (See Fig. 19.) By rotating the thumb-wheel e the roller D is correspondingly moved to feed or move the paper as desired. By adjusting the screw 61 the limit of oscillation of the pawl or lever 61 is altered, as described, to obtain the necessary spacing for the lines. By mounting the end 6 of roller E in the swivel or hinged connection c" said roller can be raised at its free end e as indicated in Fig. 20, for convenience in inserting and removing the paper onto and from the carriage. By pivoting the catch 8 and the hinged or swivel connection a in vertical slots in the standards 0 c respectively, any thickness of single paper or any number of sheets of papers can be easily and readily inserted between the rollers D and E and-subjected to pressure of a uniformly-increasing character, so that the same will not slip one upon the other as they are fed through the rollers. By mounting the end 61 of roller D in the sleeve o it is adapted for easy and quick removal for repairs 01' for substitution, and this feature provides for the substitution of a soft for a hard faced roller, or vice versa, according to the character of the work to be typewritten.
Adjacent to the front and bottom of roller D is a curved presser-plate F, Figs. 20 and 21, pivoted at f and f to the standard 0 and standard-section c respectively, and having pressure spring or springs f for normally maintaining the upper edge f of plate F in contact with the roller D or the paper thereon. If desired, the outer face of plate F at its edge f may be graduated, as shown at f To limit the extent of travel of the carriage 0, adjustable collars f" may be located on one of the rods 0 c at one or both ends of the same, as more plainly seen in Fig. 20, which collars strike against the sides of the frame A to limit the travel of the carriage.
To insert the paper in the carriage G, the catch 6 is first withdrawn from engagement with the end 6 of rollerE, and the latter, with the roller D, is raised, as indicated by full lines in Fig. 20. The paper is then placed upon the plate F. The roller D is then dropped into position, the end of the paper brought to the top of roller D, and the roller E is returned to its normal position, the catch 6 automatically re-engaging itself with the roller E to lock it in position. As the thumb-lever (Z is moved to feed the paper through the rollers D and E, they bot-h rotate to effect such feed, and as the roller E has a forcible pressure on the paper it is prevented from slipping, and as the roller E is made up of a number of separate elastic collars e they can be adjustedto suit different widths of papers.
Upon the top of the front side of the way a and adjacent to the carriage C are located the underscoring, canceling, or other like marking devices G, which consists of a pivoted plate g, havin a reacting spring g, suitably connected therewith for maintaining it in its normal position. The plate g has two faces g and g", preferably placed obliquely to one another, as shown, and parallel with said faces and located upon the top of plate 9 are are boxes g and g respectively, in which are mounted the marking-wheels g and inkingrollers g These wheels 9 and rollers g in the different boxes may be differently arranged, according to the marking to be done. Thus, for instance, the wheel 9, when used for underscoring, has its shaft vertically lo cated, as is also that of its inking-roller, as shown at .00, Figs. 1 and 3, and when used for marginal scoring or for lines running length- Wise of the paper said wheel. and roller have horizontally-located shafts, as indicated at 1 Figs. 1 and The wheels g have, preferably, serrated or toothed peripheries to mark a dot ted or broken line; but in case a full line is desired said peripheries will be unbroken, and an additional toothed wheel is secured to the said wheel-shafts for engaging with and causing a positive rotation of the inking-rollers, as shown in the drawings. By turning the plate g until either of its faces 9 g are parallel with the carriage-roller D the wheels 5 come into contact with the paper, and then by either sliding the carriage O to and fro or by having the thumb-wheel 0 to rotate the roller D and the paper the proper marking on the latter is effected. \Vhen the plate 9 is released, its spring g returns it to its normal position.
lVhere differentcolored inks are required for underscoring and analogous operations, more than one plate with marking-wheels g, may used, as shown in Fig. 1, wherein said devices are indicated in their normal position, Fig. 3 representing one of said devices turned in position for use.
Suitable openings g" are provided either in the top or in one of the sides of the boxes g adjacent to the inking-rollers 9 for supplying them with ink. The fastening of the boxes g" g, with contained marking devices, to the single plate g provides a compact and economical form of underscoring devices G, which are easily and quickly placed in position for use and which are automatically returned to their normal positions.
H represents the type-wheel, which may be of any suitable construction, preferably having all the characters of a field in a single peripheral row, and is mounted loosely upon the upper end of a shaft h, resting upon a collar it, fixed on said shaft. The said shaft 71, is mounted in a frame 7L2, rigidly secured to a cross-shaft 7L3, said shaft h passing down through said frame 7L2 and shaft 7L3 and depending below the shaft h as more plainly shown in Fig. let. The top of the frame 71. is provided with a finger 7%, which enters an a11- nular recess 765 in a sleeve 7t 011 shaft 72 To sleeve h is secured a pinion 71F, an eccentric stopping-ratchet 71 and a concentric steadying ratchet-wheel 71.", said parts being rigidly secured to said sleeve h between top nut h and bottom collar h". The ratchet has teeth of different length graded from an initial point and moving in different paths. It is preferably double, with each part having teeth of different length and graded from an initial point in opposite directions.
Projecting from the eccentric stoppingratchet h is a crank-pin 7L", which engages the type-wheel by passing through an eccentrically -located opening therein, as more plainly shown in Fig. lit, so that while said type-wheel is free to be raised, as hereinafter described, to bring the different rows of letlers into the field of action it rotates positively with the pinion 7L and the stopping and steadying rat-chefs 7t and it to position the letters or characters of said rows.
1 and I represent the segmental racks meshing with pinion 717. These racks are loosely mounted on the crossshaft h and are each provided with a laterally-extending frame it, which is loosely journaled on shaft 7L3.
J represents the movable pawl in front of the stopping-ratchet h, which pawl J is secured to frame J, also loosely mounted upon cross-shaft ha in front of the frame t i, and is provided witha retracting-spring J 2 for nor mally keeping the pawl out of engagement with the stopping-ratchet 7L8.
Located upon the cross-shaft h between the racks I and I and their respective frame ends 1" area series of tumblers K, one for each key lever B in operation with said racks, and which may be of any suitable configuration to actuate said racks I I and the pawl J by contact with their frames. I have shown in the drawings (see more plainly Fig. 18) apreferable form of said tumblers, which has a slot 76 open at the rear edge and concentric with the axial support of the tumbler. It also has a forwardly-projecting arm 70 and a segmental gear part 70 on its front edge, which mesh with consorting teeth 17 on the end b of the key-leverB in connection therewith. The tumbler-arms k rest upon the top of said keylevers B, and the upper rear corner of the end I) of said levers B above their toothed part Z) are made rounding, as shown at 5, for a purpose hereinafter described. The racks I and I each with their separate frames t t" are independent of each other, as they are loosely mounted 011 the cross-shaft 72 on opposite sides of the shaft h. The upper part of the edge 70' of the tumblers K, as will be more plainly seen in Figs. 4 and 18, are normally in contact with or abut against the frame-bars i, while the depth of the tumblerslots 70 is varied in the different tumblers contacting with each frame, as indicated by dotted lines in Fig. 18, so that the bottoms of said slots of the different tumblers will variously come into contact with the frame J for pawl J to move it into engagement with the tooth on the ratchet corresponding to the keylever depressed, said movement of the pawl J occurring at the end of the rotation of the type-wheel in positioning a letter. As the racks I and I are independent of each other, a movement of one rack causes the pinion 7L7 to roll upon the other rack, which remains stationary. This rolling movement of the pinion is imparted to the sleeve h, and hence to the ratchets h h and to the type-wheel, and as this rolling motion is also a forward movement said parts, together with the typewheel shaft and its supporting-frame 7L2, are propelled toward the carriage C while the type-wheel is rotatively moving. In other words, the initial depression of a key-lever B through the medium of the tumbler edge 75 instantly moves one of the racks I or I to impart to the type-wheel a combined axial movement and a vibratory movement toward the carriage C, said combination movement being due to the rolling of the pinion upon either the rack I or I, as the case may be, which is not being moved. The advantages of this construction are important and quite manifest. WVhen the type-wheel is first rotated and then moved laterally during the continuous downward movement of the key, the inertia of the parts has to be overcome,
as follows: first, to start the wheel moving rotatively, then to stop its rotation, then to start it moving laterally; but in the construction just described the wheel is started moving both laterally and rotatively simultaneously, and at the beginning of the stroke of the key-lever when it receives an impetus from the impact of the finger upon the key, and the continuous downward movement of the key-lever, which is effected by the pushing action of the finger, is not retarded by the added work of overcoming the inertia of the moving parts. It should be noted that in my construction the initial movement of the type-wheel is a dual movement-that is, it moves both rotatively and laterally simultaneously from the start-and that the type-wheel has such dual movement from the beginning until the type is positioned and then only a lateral movement, and that this entire action is effected by a single mechanism and not by a dual mechanism. Hence the resistance from friction and from overcoming the inertia of parts is reduced to a minimum, and the chief part of this resistance is overcome at the beginning of the movement of the key-lever when it receives the impact of the fingeia, A further advantage is that the action of the machine may be more rapid when the rotary and lateral movements are effected simultaneously. It will be observed that as any tumbler K commences to act upon a rack-frame i t" the center of axial motion of the type-wheel and its associated and coincidently-moving partssuch as the stopping-ratchet h lS moved away from the pawl J; but as the said stopping-ratchet is eccentric and has its lobe normally on the opposite side of the shaft from the pawl J the teeth of the ratchet will, as it moves axially and also laterally, pass in close proximity to the pawl J, which remains stationary until moved at the proper time, and hence it will only require a slight movement of the pawl J to engage any of the passing teeth of the ratchet 71 The movement of the pawl J is effected by the bottom of the slot 76 on the tumbler K coming in contact with the frame J. The axial movement of the type-wheel N is stoppedwhen the tumbler K has come in contact with the frame J, and thus moves the pawl J into contact with the stopping-ratchet 7L8. After this has occurred the continuous movement of the keylever will continue the lateral movement of the type-wheel until said wheel comes in contact with the platen. As the pawl J has to be moved through only a very short space to engage with the eccentric ratchet-teeth, such pawl does not jump or rebound from the ratchet under rapid manipulation and thus permit the velocity of rotation of the typewheel and eccentric ratchet to carry the latter past the pawl and thereby defeat the positioningof the letter required; but if the type-wheel and its accompanying ratchets have made an extended traverse before they are stopped by the pawl J the momentum they have acquired may cause the ratchet to rebound from the pawl J and move backward and then be caught by an improper tooth. To avoid this, a second pawl L, which is located diametrically across the ratchet from the pawl J, is provided. This pawl L is supported by a frame Z, which is loosely journaled on the cross-shaft 7r, so that it may move independently of that shaft or with it if engaged by other parts moving with said shaft it A spring Z is in engagement with the f ramel to hold the pawl L toward the ratchet, and a stop Z on the frame A holds the pawl from premature engagement with the ratchet. In order for the pawl I. to engage the ratchet 71. the type-wheel must move forward until the ratchet is brought in contact with said pawl L. The two pawls J and L normally stand in line with the lobe of the ratchet with the shaft 72. nearest the pawl J, and as the type-wheel is moved axially and laterally at the same time and the pawls stand still the lobe of the ratchet moves to one side and the shaft approaches the pawl L in a straight line, and both pawls are at all times in the same close proximity to the teeth of the ratchet. As soon as the pawl J is moved into contact with the ratchet lt by the bottom of the slot 7; on the tumbler K contacting with the frame J, the ratchet is pressed simultaneously against the pawl L, which engages a tooth on the opposite side of the ratchet which points oppositely to the tooth engaged by pawl J, so that the ratchet is not only stopped, but locked, and cannot rebound from the pawls. The two pawls J and L act like a pair of pinchers, which grasp the ratchet on opposite sides and in contact with oppositelypointed teeth. This construction is very important, as it insures the absolute precise and instantaneous stoppage of the type-wheel. It is illustrated clearly in Figs. 16, 17, and 18. As the type-wheel has a combined axial and lateral movement from the start, it follows that the inertia of all the parts moving with the type-wheel in making its forward movementmust be overcome at the beginning of the depression of the key-levers, and to make this action of said levers as delicate and easy as possible I provide the tumblers K with the arms le the under straight sides of which rest on the curved ends Z) of the key-levers, thus obtaining a long leverage at the beginning of the depression of the key-levers, which long leverage is quickly changed to a short one as the teeth b of levers B mesh with the teeth 7.". of tumblers K, the object of this construction being to obtain an easystarting movement without lessening the time of the stroke or lengthening the arc of movement of the key-levers materially.
I have shown the tumblers K provided with the teeth 75, the arm 73, and the lever ends provided with a curved face b and the teeth b, thus giving a combined cam or wiper and gear movement; but it is evident that the tumblers K and the end Z) of levers B may be variously configured to provide for such described leverage, and I do not therefore desire to be limited to the precise construction shown.
Just before the type-wheel makes the impression one of the notches of its concentric ratchet-wheel it engages with a fixed pawl Z on the frame of the machine, which steadies the same and holds it against any movement that might occur through lost motion due to looseness or wear of any of said parts, and thus perfect positioning of the impressions are secured. Said pawl Z is more plainly shown in Fig. 7, which illustrates the type wheel in position at the end of its forward movement.
The frame 71?, in which the shaft h of the type-wheel II is swiveled, is fixed to the shaft 713, and when the said frame 7L2 and-the parts carried thereby are vibrated by the other actuating parts the shaft 7L3 is moved on its journals. Hence to retract said frame 72. and the parts which are carried by it I put on said shaft a spring Z, which has one end in engagement with the arm Z, ertendiug from said shaft, and the other end in engagement with a tension-rack l on the frame, (see Fig. 11,) and by changing the end of the spring 1*, which is in engagement with said rack Z from notch to notch,the degree of resistance of said spring is varied. This spring Z when the operating-keys are released, moves the operating parts back to normal position.
Any suitable form of inking device may be used for the type-wheel. In the drawings I have shown an inking-roller I, mounted in a pivoted orswinging arm Z having a stop end 1, which arm is supported upon a rod Z in a bracket Z. (See Figs. 1 and 7.) This inking-roller is vibrated solely by the vibratory motion of the type-wheel, thereby dispensing with all mechanism for moving said vibrating roller independent of the vibrating wheel. If desired, the rod I may be provided at both ends with a pivoted inking-roller for different-colored inks to be independently used, and by making the arm or rod Z removable from bracket Z the different inking-rollers may be changed for use as desired. In some cases I prefer the form of inking device shown in Fig. 12, wherein the ink-roller I is made of soft rubber or other elastic material and has a separate supply-roller Z, so as to avoid having an undue amount of ink on roller Z and thus preventing blurred impressions. In this case the arm Z has a bifurcated end P for limiting the extent of its swinging motion, and the rod Z" has a cross-pin P for engagement with the slotted end l of bracket Z to maintain the rod Z in position, whereas in Fig. 7 such securement is provided for by the spring-catch 1" entering a groove Z in the rod Z. The inking -1'oller Z is located in line with the type-wheel adjacent to the carriage C, so that said type-wheel at or near the end of its propelling movement ICC) will cause the roller to revolve to ink said letter, and also cause it to fly up out of the way of the type-wheel as it makes the impression. It will be noted, therefore, that the type-wheel alone actuates the inking-roller Z The rack c of the carriage O meshes constantly with an actuating-pinion n on a shaft N, (see Figs. 8, 11, 20, and 23,) which, as shown, runs lengthwise of the machine to one side of the same, as more plainly indicated in Figs. 1 and 8. Upon the cross-shaft 71 adjacent to shaft N, is a double-faced pawl M, which. is connected to said shaft 711 ,80 as to oscillate with it and yet have a lateral oscillation of its own on said shaft. This pawl n has a cam-face n 'in advance of a side flanged face or, which is curved concentric with the axis of the pawl while the cam-face n is eccentric to the axis. The pawl 01. hangs from the shaft 71;, parallel with and at one side of the shaft N, adjacent to a ratchet-wheel it, which is rigidly secured to said shaft N. This wheel a as more plainly shown in Figs. 11 and 23,is indented with substantially parallel-sided notches, and the ends of the teeth thus formed are slanted inwardly, so that one side of the radial notches pawl n to contact with the end of the longer side a of one of the teeth, and imparts a downward motion to the wheel of and turns the shaft N and wheel a to feed the carriage the necessary space for the letter or character to be printed, which feed is effected before the impression is made. As soon as the cam end a of the pawl passes off of said tooth the curved flange or, immediately following on the pawl, enters into the radial notch between said tooth and the succeeding tooth, as shown in Fig. 11, and locks said wheel n shaft N, wheel 72, and consequently the carriage O in position after ithas been positioned to receive the imprint of a letter and continue to hold it while the impression is being made. As the shaft 7L3 reversely rocks upon the return of the type-wheel the pawl is correspondingly moved to cause its flange to disengage itself from wheel H and as the cam end 01 of the pawl passes by the wheel the spring 01 which bears against the top of the pawl oscillates or'throws it to one side on shaft 7L3 to its normal position, which is at an angle to shaft 71 for successive action upon the wheel n to effect the further feeding of the paper-carriage.
0 represents a second ratchet-wheel on shaft N, similar in all respects to wheel it, except that the wheel 0 is provided with a other purposes.
collar 19, against which normally rests a second pawl P, connected at p to a roek-shaftp to rock with said shaft and at the same time be capable of swinging laterally, and provided with a spring ja which acts to move said pawl laterally onto or in the direction of said collar. Said pawl has a lower inside-edge flange p and cam-edge p, the same'as for pawl 02 except that the former are located reversely to the latter. In front of the wheel 0 stands a spring-guard 19 The pawl Phas a link connection 19 with an arm 19 on a cross rock-shaft 19 near the front end of the machine, to which is secured the spacer-har o the same having a suitable retracting-spring p If desired, thelink 1) maybe provided with stop-lugs 19 191 and an abutting-roller 19 the latter of which may be of leather or analogous material to lessen the noise of operation. A depression of the spacer-bar p rocks shaft 13 to cause its arm p to draw the link 1) forward and correspondingly oscillate the pawl P and in so oscillating it passes to the outside of the spring-guard 135 until it passes by the same, whereupon its spring p swings it laterally toward the wheel, so that upon the return stroke its cam end 19 and flange 19 act upon the ratchet-teeth, as in the case of the pawl 01 and moves the wheel 0 and shaft N with its wheel n to feed the carriage for spacing between words, the flange p on the pawl P locking said parts in position while the impression is made as it passes through the spaces between the teeth on the return movement of the pawl P. As the pawl 72 moves the shaft N and feeds the carriage on the forward movement and the pawl P effects a like result on its return stroke, it follows that if e a keylever l5 and the spacer-bar 139 be depressed simultaneously the carriage will first be fed before the impression is made, and after it is made it is further fed to space between the character or letter so made and the next succeeding impression, and in this way the last letter of a word and the spacing between such and the succeeding words can be made at one instead of by two operations.
The operation of the foregoing-described pawls is easy and delicate and practically noiseless. It will be noticed that the earriage-rack c is always in engagement with its actuating-wheel 01; but as the pawl devices a and P are normally out of engagement with the ratchet-wheels n and O the carriage O can be freely moved in either direction for wide spacing, underscoring, canceling, or
that both pawls n and P move the shaft N, so that one actuating-wheel n successively :feeds the carriage for spacing for the impressions and for spacing between words or letters orcharacters, as desired.
R and R represent the shifting-keys for the type-wheel, so as to bring its different rows of letters or characters into the field of action. These keys pass through slots 1" in the front plate 9* of the machine, and said It will further be noticed slots are provided with shoulders or offsets r for holding the keys in. their depressed position when desired to do so. These keys, together with the keys B, are mounted upon the cross-bar a and their inner ends abut against an arm '1' projecting from a swinging rack r mounted on bar a, which rack meshes with a pinion r on a shaft 0, running lengthwise of the machine and provided with a suitable retracting-spring r for returning said shaft and the coacting parts in connection therewith to their normal positions. The keys R It are also provided with retracting-springs 7-. (See Fig. 6.) At the rear end of shaft 0' is a downwardly-projccting arm 1' which is bifurcated at its lower end r, and engages with a sliding collar 8, (see Fig. 11,) having a downwardly-projecting arms, with roller .9 for engagement within a slot 6 in an arm T, pivoted at its end i to an arm 6 affixed to shaft ha, and provided with a retracting-spring F. The opposite end i of arm T engages with the type-wheel shaft 7r. A depression of either of the keys R R oscillates the rack to rock the shaft 1 and its arm 7', which in turn slides the sleeve 5 on shaft its to rock the arm T to raise the shaft 7L and the type-wheel II to bring the desired row of characters into action. As the sleeve 8 is loose upon shaft 7t and as the arm T is supported by said shaft, said sleeve and arm rock with shaft its as it is moved, so as to keep said sleeve and arm always in the line of the type-wheel. shaft h.
It is obvious that the construction and arrangement of the novel features of my invention may be variously provided for without departing from the spirit of the same. Hence I do not limit myself to the constructions and arrangements shown. The tumblers K and the ends 11 of the levers B are separated by or work in the slots of the comb V, being preferably so arranged that the teeth of said levers and tumblers mesh with each other in the comb, so as to maintain such engagement from end to end of the movement of the toothed parts of the levers and tumblers without lateral motion. In other words, there are no side supports for the joint formed by the tumblers and levers other than the comb, which prevents said parts from moving later ally, and therebydestroy the alignment. The key-levers 13 are notched on their underside and are hung upon the shaft to. To prevent them from binding upon these supports, a comb V is provided. This comb is placed over the levers and prevents dust and dirt from accumulating at the joint, and also sepaarates and holds the severallevers in place. This is an especially desirable result, so far as the outer levers are concerned, as it prevents them from bending over sidewise or tilting. The comb is placed directlyover the shaft or bar a and is secured in place in any desired way.
