Figs. 21, 22,26, and 27 are drawn to an enlarged scale.
In the drawings, A is the base-plate or bed of the machine, provided with the two up wardly-projecting ribs A A, each having 7 formed in its outer vertical face a shallow longitudinal groove, (1, and a series of circular recesses, in each of which recesses is mounted upon a suitable stud or journal an antifriction truck, I), so arranged that its periphery projects slightly above the upper edge of said rib, and its outer face is sunk into said rib to a point at or near the bottom of the groove a, as shown in Fig. 1 at the left hand thereof.
B is a carriage, consisting. of a rectangular plate which rests upon the antifriction trucks 1) b and is provided with two downwardly-projecting ribs, 0 0, each having formed thereon or secured thereto the inwardly-projecting lip c, which fits into the groove a and serves to guide said carriage in its movements to and fro upon the bed. Said carriage Bis also provided with two upwardly-projecting ribs, d d, in'the outer vertical face of each of which is formed a longitudinal groove to receive theinner edge of a longitudinal bar, 0, of the upper carriage, C, in suitable bearings, GC, of which is mounted the paper-carrying roll D, having its periphery covered with rubber or other suitable elastic material in a well-known manner.
E E are two goose-neek-like stands secured upon the base-plate A, and to the rear ends of which the casing of the head of the machine is pivoted at E and locked in a fixed position by the bolt E in the same manner as described in my before-cited prior application, except that the pivots for said head are at a greater distaneeabove the base plate than the lockingbolt, so that when locked in its normal position the base of said head and the plane occupied by the finger-keys shall be inclined toward the front of the machine, as shown in Fig. 2, for the purpose of rendering the keys more conveniently accessible to the operator.
The casing or frame of the head of the ma chine is composed of the base-ring F, the capring F, the thin sheet-metal panels or middle section, F and the central cap-plate or cover, F", as shown in Fig. 2. Upon the upper edge of the base-ring F are secured a series of twenty-six brackets, G, each provided with two downwardly-prejecting ears, f f, between which is pivoted the short sleeve G, so that it may be moved in a vertical plane only. In each of said sleeves Gis fitted, so that it may be moved about its axis, but cannot be moved endwise in said sleeve, a type-bar, II, provided with a shoulder to abut against one end of said sleeve and having secured upon its outer end a bevel-pinion, y, the hub of which abuts against the other end of said sleeve, as shown in Fig. 6. The inner end of the type-bar His made triangular in cross section, and has formed thereon in relief a capital letter, a small letter, and a figure, punctuation-point, or other character, substantially in the same manner as described in my before-cited application. The inner end of each of the sleeves Gis provided with the downward]y-projecting ear g, to which the bifurcated lower end of the keyspindle I is pivoted, as shown in Figs. 2, 4, and 6. The spindles I are fitted to bearings in the screw-bushings h, set in the cap-ring F, and have secured upon their upper ends the key-buttons I, said keys and spindles being arranged in a circle and equidistant from each other, as shown in Fig. 1. The keys and typebars are maintained in their normal or ele vated positions by the wire springs h, one end of each of which is set in ahole in or secured to one of the brackets G, and the other end is inserted in a hole extending transversely through a spindle, I, asshown in Fig. 6. Each spindle I is slotted just below the bushing h to receive one end of a lever, J, which is pivoted thereto, and is provided with a slot, 1', through which passes the wire ring-like fulcrum-pin J, common to the whole series of said levers, said fulcrumring being fitted to a circular groove formed in the under side of a series of downwardly-projeeting lugsj, formed upon the -nnder side of the central cap-plate, F, and so shaped as to serve as guides to separate and keep at equal distances apart the levers J, said fulcrum-ring being secured to said lugs by means of screws set in certain of said lugs j, with one side of their heads bearing in recesses formed in the outer sideof said fulcrumring, as clearly shown in Figs. 26 and 27. The inner ends of the levers J are curved downward, and terminate in upwardly-projecting noses or tips 7., which, when the key I is depressed, come in contact with the lower end of the short central spindle J and move it upward in its bearing in the cap-plate F". The spindle J is provided with an annular flange at its lower end, and has formed therein a slot to receive the inner end of the lever K, which is pivoted to the ears 7.2, east upon or secured to the under side of the cap-ring F, and has its lower end forked and its inner end pressed downward by the spring 7;, all-as shown in Fig. 4.
L is the space-key lever, pivoted to a stud set in the cap-plate F and to the upper end of the spindle J", so that by depressing said key the spindle J and lover K may be operated to feed the carriage independently of the operation of the type-bars whenever it is desired to leave a space between words.
13y virtue'of the slot 2' in each lever J and the positive connection of the outer end of said lever to the key-spindle I, the nose 7.: of said lever will move very nearly in a straight vertical line when the key is depressed, thereby materially reducing the friction between said nose and the spindle J".
L is an annular or ring-gear fitted to a suitable bearing on the base-ring F, and with which each bevel-piniong engages when its type-bar is in its normal or elevated position, as shown in Figs 2 and 4. The base-ring F is provided with the curved slot Z, directly seas-7o 3 beneath the ring-gear L, through which the radially-projecting arm L is secured to said,
ring-gear by the screws Z Z, as'a means of moving said ring-gear a limited distance in either direction about its axis, for the purpose of par-.
tially revolving all of the type-bars simultaneously. The arm L has set in its under side a pin, m, provided with a head composed of .two long laterally-projecting arms, at, suiticicntly removed from contact with the under surface of said arm to permit the insertion be-' tween said parts of the free ends of the two wire springs a, secured to the under side of thebasering F, by the screw-studsna, around which said springs are coiled in such a manner as to press with considerable tension against opposite sides of the pin m, as clearly shown in Figs. 2, 8, and 9, by virtueof which arrangement of parts the arm L is maintained in its normal position centrally of the slot Z,
unlessforcedin one or the other direction therefrom, which action increases the tension of the spring upon the side toward which said arm is moved, the other spring being prevented from following up the pin in by coming in contact with the pin 0; and when the pressure or forceis removed from the arm L the spring immediately returns the arm L to its normal or central position. When the arm L is in its normal or central position, the type-bars are in position topri'nt the small or lower-case letters if they are depressed. If the arm Lf be moved in one direction from said central position all the type-bars will be rotated onethird of a revolution and bring the capital-let ter faces of said bars into position to print when said :bars are depressed, and if said arm L is moved in the other direction from said central position the typebars will be rotated onethird of a revolution in the opposite direction and bring the faces of said bars upon which are formed the figures, punctuationpoints, &c., into position to print when the said bars are depressed.
M is a three armed lever pivoted at 0' to the stand M, secured to the exterior of the base ring F, at the front side of the machine, the lower arm of which is bifurcated and embraces the outer end of the arm L", and the other two arms,extending obliquely to the right and left of the pivot, about which it may be vibrated, are each provided with a suitable broadened pad-like surface in aconvenient position tobe pressed by the thumb or finger of the operator to move the ring-gear ineither direction to partially rotate the type'bars. The lever M is provided with a pin, 1), set in a bearing therein, with a spring, 1), arranged to press said pin into a detent notch in the stand M when said lever M is in its normal or centra position, as shown in Figs. 2 and 8;
Upon the inner face of the upright p )rtion of the base-ring F are formed orsecured a series of inwardly projecting vertical ribs, q, the inner edges of which are curved to an arc of a circle struck from the pivotal axis of the typebar, the number of said ribs corre the spending to the number of type-bars used, and the center of each rib being in the same vertical plane as the axis of a type-bar. Each bevel-pinion on a type-bar has formed in the outer end of its hub three grooves, q q q, crossing each other at the axis of said gear, as shown in Fig. 5, with one of which a rib, g, on the inner face of the base ring F engages whenever a type-bar is depressed for the purpose'of correcting anyinaccuracy in the movement of the type-bar about its axis in chang ing from small letters to capitals or figures, or vice versa, said grooves being made slightly flaring at the periphery of the hub to insure engagement with the ribs q. I
N N are two flanged drums mounted upon shafts r r, so as to be movable lengthwise thereon and revolve therewith, said shafts having bearings in the stands N N, secured to the base-ring F, one upon the right-hand and the other upon the left-hand side of the head ofthe machine, as shown in Figs. 1 and 7.
bottom of the groove 1-, to hold said drum in any desired position upon said shaft relative to its length, all as shown in Figs. 15 and 16. Each shaft 1' has mounted thereon a ratchetwheel, 1", having teeth so arranged that the hook-pawl r, engaging with said teeth upon the outer side of said wheel when moved downward, will rotate its drum so as-to wind the ink-ribbon 0 upon the upper side thereof.
0 and O" are two pawl-like levers pivoted, respectively, atr and r, and each having pivoted to its outer end ahook-pawl, r, the upper end of which is drawn toward the ratchet wheel by the spring 1. (Shown in Fig. 7.)
P-P are two stands, secured one to each of fi outer 61 d two open slots, 1) and p, of different depths, the slot 1) being designed to guide and steady the upper end of the pawl T when it is in engagement with the ratchetwheel 1-, as shown at the right of Fig. 7, and the slot p being designed for holding said pawl out of engagement with the ratchet wheel, as shown at the left of Fig. 7. By this arrangement of pawls-and ratchet-wheels the ink-ribbon 0 may be intermittently and automatically wound upon the drum at the right-hand side of the machine until it is all unwound from the opposite drum, when, by simply placing the right-hand pawl 1- in the slot 1) and the left-hand pawl r" in the slot p the ribbon will be automatically wound upon the leftshand drum, the pawls 1 being moved up and down by the vibrations of the levers O and 0 caused by the action upon their inner ends of the teeth. of the ratchet-wheel P enecks E, and each having cut in itsas it is intermittently rotated in the direction indicated by the arrow on Fig. 10, the inner end of the lever 0* being formed and arranged to abut against the shoulders of the teeth of the ratchet-wheel I like an ordinary pawl, and the inner endof theleverOhaving formed thereon a hook or shoulder to engage with the same tooth of said ratchet-wheel as the end of the lever O engages wit-h, whereby said levers O and O are made to serve the double purpose of stop-pawls to prevent a backward movement of the ratchet-wheel P, and to inmittently move the ink-ribbon in one or the other direction, as above described.
I? is a horizontal shaft mounted in hearings in the ribs A A of the base A, and having firmly secured thereon the escapement-wheel P, the ratchet-wheel P, the collar P, and the clutch-disk P", and loosely mounted thereon,so that it may be revolved freely in one direction thereon, the toothed gear-wheel P, all as shown in Fig. 2. The gear-wheel I engages with a toothed rack, Q, formed upon or secured to the under side of the carriage B, so as to be rotated by the movement of said carriage, and is connected to the clutch-disk P by means of the grip-dog s, the inner end of which rests in a detent-notch, p, formed in the hub of the gear-wheel P, and having formed in its edge, near its outer end, a transverse parallel-sided notch or slot to receive and embrace the annular lip s on the clutch-disk P said dog being made to grip the said lip by the tension of the spring s, and any attempt to move the gearwhecl about its axis in the direction indicated by the arrow on Fig. 22 will cause the shaft P to rotate about its axis a distance equivalent to one tooth of the escapementwheel P, provided the escapement is so operated as to permit such movement.
It is the escapement bar or plate, forked at one end, so as to embrace and be guided in its movements by the hub of the escapementwheel P, and connected at its other end to the stud s, set in a slot, 8, formed in the lower end of the upright lever B, pivoted to the stand R and provided at its upper end with the pin 8 to engage with the forked lower end of the lever K, through which the motion of a type or space key is transmitted to the escapement-bar to cause the escapement-pinst and t to alternately engage with the teeth of the escapement-wheel upon opposite sides thereof. It will be observed that a peculiarity of this escapement is that the escapement-pins move substantially in right lines, and both move in the same direction, and the throw of said pins may be varied by adjusting the stud s" in the slot 8 to a greater or less distance from the fulcrum of the lever B. The gearwheel P is lightly pressed toward the clutchdisk P by the tension of the spiral spring 1 surrounding the shaft P between said gearwheel and the collar 1 as shown in Fig. 2. The carriage B has secured thereon the detentspring i, constructed and arranged to engage with a notch formed in one of the bars 0 of the carriage G, for the purpose of connecting said carriages B and C, so that they will be moved together when force is applied to the lower carriage, B, while at the same time the upper carriage, C, may be moved independentl y of the lower carriage. To the under side of the carriage B, at t, is secured one end of a cord, a, preferably of eatgn't, the opposite end of which is secured to and wound upon the periphery of the spirallygrooved drum S, firmly secured upon the inner end of the shaft S, mounted in bearingsin one of the ribs A of the base A and in the toothed hub S fitted to revolve in the outer end of the fixed sleeve or easing S", secured to the baseplate A, said shaft having wound thereon within the casing S the spiral spring 2f, the inner end of which is made fast to the shaft S, and 3 the paper-roll has been fed a distance equal to.
thelength of the line beingprinted,and the earriages are drawn back to commence a newline, the unwinding of the cord u from the drum S winds up or sets the spring i again ready to feed the carriages and paper-roll for printing m another line, the toothed hub S being prevented from revolving with the shaft S by the spring stoppawl a, secured to the bed-plate A, as shown in Fig. 24.
T, Fig. 2, is a bell upon which the hammer to o strikesjust before the end of a line is reached.
The hammer e is secured upon one end of the shaft U, mounted in bearings U U, cast upon the base-plate A, and has wound upon its opposite end the torsional spiral spring 2;, as
shown in Fig. 17. The portion of the shaft U between its bearings has formed therein alongitudinal groove, 22', and has adjustably secured thereon,by means of the thumb-screw o,
the point of which enters said groove 12', the II5 block U, upon the upperside of which is formed the cam or wedge surface 12, with which the lower end of the arm V,pivoted to the carriage B, engages to turn the shaft U and raise the hammer 1) against the tension of the spring 12, [20
which, when the arm V has passed the camsurfaee '0, causes the hammer v to strike the bell T as a signal to the'operator. The arm V is prevented from moving about its axis,when
acting upon the cam-surface to raise the ham- I 25 mer,by the stop-pin w,against which it is held by the tension of the spring w,eonnecting said arm to the pin wj but when the carriage B is moved back after the bell has been struck,the
arm V strikes against the end of the cam o 1 0 and is' moved about its axis until it can pass over the top of the cam, when the tension of the spring 10 causes itto assumeits normal position, as shown in Fig. 18.
In the under side of the carriage Bis set the downwardly-projecting pin 10 which engages with the pin w, set in and projecting horizontally from the rib A of the base A for the purpose of limiting the movement of the carriage B in that direction.
The toothed hub S" is provided with two holes in its outer face to receive the pins of a forked key for turning said hub to adjust the tension of the spring t, as shown in Fig. 24.
W is a stand secured to the base-plate. A in front of the carriages B and O, and having pivoted to its upper end the index-finger W, provided with the laterallyprojecting stop-pin 10*", which engages with the upper end of the stand W to limit the movement of said finger about its axis of motion in either direction. The index-finger W is designed to be kept folded by the side of the stand W, as shown in Fig. 2, except when used to register the posi-- tion of the carriage when it is desired to correct an error in the printing The construction and position of the stand W and finger Ware such that the end of the finger, when turned up into the position shown in Figs. 19 and 20, will mark the exact spot where the next type-hammer will strike upon the paper. If, upon examining the matter printed, the operator finds that an error has been made by printing a wrongletter or misspelling a word,
he turns the finger WV into the position shown in Fig. 20, and moves the two carriages together endwise upon the bed till the defective tion on the carriage 13, turns down the finger W, lowers the head of the machine to its norbeen raised to permit the movement of the finger W,) and prints the correct letter or word.
The paper-carrying roll D, mounted in bearings 00 of the carriage O, has secured upon each end of its shaft outside of said bearings the milled head 0*, for use in moving said roll and carriage endwise by hand and rotating said roll when putting in or taking out the paper. The shaft of said roll also has firmly secured thereon, just inside each bearing OO, a ratchet-wheel, O and between said ratchet wheel and the end of the roll has loosely fitted thereto a short sleeve or thimble, a, firmly secured to one end of the rod a the opposite end of which has a bearing in the slotted arm D, which embraces said thimble and has secured to its front end the bar D", to which is securedthe upper edge of the curved sheetmetal guideplate D, the purpose of which is to facilitate theinsertion of the paper between the bar D and the roll D. Each arm D has formed thereon an outwardly-projecting lug' in close proximity to said concentric surface,
Dabout its axis a distance corresponding to the desired distance between t'helines of printing, a spring, a, surrounding the rod a, between one end of the slot in the arm D and the thimble a, serving to hold said dog in engagement with the teeth of the ratchet-wheel O.and permit a slight outward movement of said dogs, with the arms D and bar D whenever the bar D is depressed, so that said dogs may pass to and engage with the next tooth of the ratchet-wheel G". A spiral spring, I), is connected by one end to the rear end of each of the arms D and by its other end to the carriage C, said spring serving to move the arms D about the axis of the roll D in one direction and maintain the bar D in its elevated position until depressed by the operator by pressing his thumb or finger upon the pad b" of the bent arm -D secured by its opposite end to the under side of the arm D, as shown in Fig. 12. .The front edges of the end pieces or bearings, O O, are provided each with two shoulderac and c, the portions of said hearing or end pieces between saidshoulders being made coneentrie with the axis of the roll, and the arms D extend across the front edge of said end pieces between said shoulders and as shown in Figs. 11 and 12. The distance between the shoulders c and c is equal to twice the distance apart of the lines of print: ing plus the width ofthe arms D where they pass said end pieces, 0 G.
In order to adapt this mechanism to feed the paper in the direction of the circumference of the roll D a distance equal to the desired distance between two lines of printing or twice that distance, I pivot to the outer faces of the end bearing pieces, 0 O, the movable step d, which hangs pendent from its pivotal axis, with its lower end a distance of a line space below the shoulder a and in position to intercept the upward movement of the arm D, as shown in Fig. 11. When it is desired to feed the paper a distance equal to two line spaces, the pendent stop is turned upward till it rests against the pin d", when the tensions of'thc springs b b will cause the bar D to move upward, moving the roll D about its axis till the upper edge of the arm D strikes the stop 0 When a line has been completed, and the operator desires to move-the paper-roll so as to place it in position for commencing a new line, he places a finger of his left hand against the end of the carriageB and his thumb upon the pad I) of the arm D and presses downward with the thumb till the lower edge of the arm D strikes the shoulder 0, thus causing the dog a to engage with a new tooth of the 'ratchet-wheel O, and at the same time he moves the carriages B and Sand the roll D to the right by pressing upon thecarriage B. When he removes the pressure from the pad I) of the arm D, the springs blr, reacting upon the arms D, will cause the arms D and D D V to be moved upward till the arms D come in contact with the pendent step d or the shoul- IOI der 0, according as to whether it is desired to feed the paper one or two line spaces. A spring stop-pawl, (P, is secured at one end to one of the end pieces, 0, in position to engage by its shoulder with the teeth of the ratchetwheel 0, the free end of said pawl extending beyond its shoulder to a point beneath the arm D, with its upper surface on a level with the outer corner of the shoulder c, as shown in Fig. 12.
Vhenever for any cause it is desired to turn the paper-roll backward, the operator presses down upon the pad I), and at the same time presses slightly forward thereon until the arm D passes the shoulder c and striking the spring-pawl near its free end disengages the shoulder of said pawl from the teeth of the ratchet-wheel C, the spring a yielding sufficiently to permit the requisite forward movement of the arms D upon the thimble a to allow the arm D to pass below the shoulder c and release the dogs a from engagement with the ratchet-wheel 0".
Just inside the milled head 0', and between it and the bearing 0 upon each end of the shaft of the roll D, is mounted a disk, d, provided with the curved slot 0' and the outwardly-projecting arm 0 the outer ends of said arms 0* being connected together by the rod 0", as shown in Figs. 1, 11,12, and 13. A pin, c set in each of the bearing end pieces, 0, projects into the curved slot 0 in the disk (1 to serve as a stop to limit theniovement of the rod c about the roll Din either direction. The object of the rod 0 is to hold down the rear portion of the paper which is passed beneath it.
' When it is desired to introduce a sheet of paper into the machine preparatory to printing thereon, the rod 0 is moved about the roll D from the position shown in Fig. ll to a position in close proximity to the bar D'-. The sheet of paper is passed between the roll D and the curved guide-plate D from the rear until it enters the bight between the roll D and the springs D D secured upon the carriage O and projecting upward through the guideplate D and between the roll D and the bar D, when the roll D is rotated in the direction indicated by the arrow on Fig. 13. YVhen the paper has reached the desired point, the rod e is moved back intothe position shown in Fig. 11.
In each of the brackets G (see Figs. 2, 3, and 4) is fitted a set-screw, c, to serve as an adjustable stop to limit the upward movement of the typebar II.
It will he observed, by reference to Fig. 7, that the plate of the carriage 13 extends be yond the ribs 0 and d and has set in its upper side the headed pin 13, and by reference to Fig. 14 that the carriage G is provided at the opposite end and its under side with the lipped socket Bi, open upon its inner side, which engages with the head of the pin B when the carriage O is drawn toward the left hand to the limit of its movement in that direction,
when the carriage 0 maybe moved about the pin B as a pivot into a position at right angles, or nearly so, to the carriage B, the object of which is to render the placing of the paper upon the roll more convenient than with said carriage (l in its normal position upon the carriage B.
If for any purpose it is desired to remove the carriage O entirely from the carriage B, after it has been brought into engagement with the pin B and turned at right angles, or nearly so, to the carriage B, the operator has onlyto move the carriage slightly to the rear to disengage the socket 13 from the pin B.
