$PECIFICATIQN forming part of Letters Patent No. 640,254, dated January 2, 1900.

Application filed May 9,1898. $erial No. 680,205. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK F. ANDER- SON, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Type-IVritin g Machines, of which the following is a specification.

My invention relates to type-writing ma chines; and my object is to generally improve the machine upon which Patent No. 597,664: was granted to Theodore Krauss, of Argentine, Kansas, and myself on the 18th day of January, 1897, such improvements embodying, first, an oblite1-ating-keyt'. 8., a key by which the typeimpression on the paper may be completely obliterated; secondly, a hinged paper-carrier and a key-operated mechanism for raising part of the same and exposing the characters made by the type; thirdly, means for shifting the carriage forwardly or rearwardly from its normal or central position to dispose the paper to receive the impressions from type of different styles or characters; fourthly, to synchronously lock the carriage at'any predetermined point in its travel and the type-levers from contact with. the paper after such position is attained by the carriage; fifthly, means for unlocking the carriage to permit a few extra steps of the same and the keys to make a corresponding number of typeimpressions on the paper; sixthly, means to reloek the carriage at its utmost point of travel and the keys from further operation;. seventhly, means to release the carriage and keys, that the former may return to its initial position for the beginning of a new line and the latter be free to operate; eighthly, means to prevent momentum or reactionary action of the carriage at the end of each step and guides for insuring the contact of the type at the proper point on the ribbon, and thus insure equality of space between the characters and regularity of printing; ninthly, improved means to obtain double or single space between lines automatically or by hand; tenthly, means to permit of line-printingatanyintermediate point between the regular double or single spacing intervals; eleventhly, means to limit the up movement of the type-levers to avoid chance of injury to the type or the platen; twelfthly, a detachable platen provided with a souud deadeniug cushion, and,.

lastly, a bell mechanism which operates just before the carriage and keys are locked the first time.

Other objects of the invention will hereinafter appear, and be pointed out in the ap pended claims, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which-- Figure 1 represents a top plan View of a type-writing machine embodying my invention. Fig. 2 is a vertical section taken on the line II II of Fig. 1. Fig. 3 is a section taken on the line III III of Fig. 2.

Fig. 16 is a sectional view taken on the line XVI XVI of Fig. 15. mechanism for preventing the depression of the character or word spacing keys. Fig. 18 is a section taken on the dotted line XVIII of Fig. 10. Fig. 19 is adetached perspective view of the swinging frame and rods for con necting the same with the spacing and character key levers.

In the said drawings, 1 designates the bed or bottom, 2 the back, and 3 the top plate, of a type-writing machine.

4 designates a forwardly-projecting shaft Fig. 17 is a perspective view of the which is secured as shown or in any other suitable manner to the back plate and preferably Vertically above the center of the same, and journaled thereon is a cable-wheel 5 of such diameter that it projects up through the slot 6 in the top plate. At its front margin it is provided with radial notches '7, which exceed in number the steps taken by the carriage when moved from its initial position to its utmost limit of travelthat is to say, which exceed the number of characters which can be printed in a single line-and engraved upon the front face of said wheel is a dial, which is numbered to correspond with the said notches for a purpose which will be hereinafter explained. Mounted pivotally upon said shaft at the front side of the wheel is a Walking-beam 8, held reliably in place by a retaining-nut 9, as shown, and screwed upon said shaft, rearward of said walking-beam, is a nut or collar 10, which holds reliably in place upon the shaft and against the face of the wheel the spring-metal hand 11, formed near its lower end, preferably, with an opening through which the numbers upon the dial may be observed and a .finger 12 to register with said numbers, and at its extreme lower end it is provided with the lug 13, having a beveled tooth 14 at its rear side, said tooth being normally engaged with a notch of the wheel to prevent movement of the wheel unless accompanied by like movement on the part of said arm.

At one end the walking-beam is preferably weighted, as at 16, and carries the dog 15 for engagement with the notches of said wheel, and'at its opposite end it is pivotally connected by a pull-rod 17 to the front end of the arm 18 of a shaft 19, preferably journaled in a bracket 20, mounted upon the bed of the machine. A swinging frame 21, pendent from said shaft, is provided with the vertical slots 21", connected by a cross-bar 21", which is adapted to play in said slots, and said frame is connected by a comparatively stiff spring 22 to the arm 18. By this construction it is obvious that the movement forward of the pendent frame causes rotatable operation of shaft 19 and the depression of arm 18 until it strikes the stop-pin 23, erected from the bedplate. Further movement of the shaft and arm is thereby arrested; but the frame may continue to move forwardly, because the spring 22 will expand under sufficient pressure applied upon the type or spacing-keys, as hereinafter explained.

The stop-pin 23 is provided near its lower end with apassage 24, extending from front to rear, and with the intersecting transverse passage 25, the base of passage 24 being in thehorizontal plane of a shelf or support 26 and the base of the passage being in the horizontal plane of a shelf or support 27, said shelf or support being provided with parallel guide-ribs 28 for a purpose which will hereinafter appear.

The carriage-adjusting frameviz., the

' original position.

frame for moving the carriage from a central position forwardly or rearwardly, so as to dispose the platen to receive the impact of type of difierent characterscom prises the bar 29, provided with the parallel arms 30, which extend forwardly through the back of the machine just below the top plate, and said frame is supported upon the grooved rollers 31, journaled in brackets 32, depending from the top plate. At suitable points between said brackets pins 33 and 34 depend from the top plate, and 35 designates collars or washers upon said arms 30, which are pressed rearwardly against pins 33 and forwardly against pins 34 by means of expansion-springs 36, said springs encircling said arms and bearing at their opposite ends against said brackets and by neutralizing each other tend to hold the carriage-adj usting frame in its normal or central position, as hereinafter more particularly referred to, and projecting laterally, by preference, from the arms 30 are pins 37.

38 designates standards secured to the bar 29 and to'the front ends of arms 30, the standards of the latter therefore extending upwardly through slots 38* in the top plate of the machine,(see Fig. 1,) and 39 and 40designate superposed grooved. rollers supported by said standards.

The carriage proper of the machine is of substantially rectangular form, consisting of front and back bars 41, which titsnuglyin and between grooved rollers 39 40, and the crossbars 42, connecting bars 41 at a distance apart slightly exceeding the width of the top plate, as shown in Fig. 1, said bars 42 being of the configuration illustrated most clearlyin Figs. 2 and 4--that is to say, having their rear por tions raised and arched for a purpose which will presently appear, and secured at their upper ends to said rear or arched portions of the bars 42 are arms 43 of a horizontal gage 44, said arms beingutilized as points of conriection for the opposite ends of the cable 5, secured to and encircling one or more times the wheel 5. This connection between the wheel or drum 5 and the opposite ends of the gage-bar carried by the carriage obviously causes the latter to travel toward the left or right, accordingly as the wheel is turned through the instrumentality of key-actuated devices or by the carriage-returning spring hereinbefore described-that is to say, when the wheel is turned step by step by the dog 15 in the direction indicated by the arrow, Fig. 3, that part of the cable extending toward the right from the wheel is wound up, and consequently pulls the carriage toward the left, the cable paying out toward the left at a proportionate speed. This action of .the cable is reversed to cause the carriage to return to its initial position when said carriagereturning spring rotates the wheel back to its Said gage-bar 44 embodies a plurality of parallel slots of equal size and spaced to correspond with the notches of the wheel 5, and consequently with the distances between characters printed by the machine, the slots extending from front to rear and being of sufficient length to accommodate the reciprocatory stop-pin 45 in the back-andforth movement of the carriage adjusting frame. Said stoppin 45 projects up through the top plate and is connected by a link -16 with the walking-beam, or, rather, with the Weighted end of the same, and the upward movement of the said weighted end caused by each depression of a character or word spacing key is accompanied by a like movement of said pin and its consequent engagement with one of the slots of said gage-bar, so as to absolutely arrest the carriage at the proper point, and thereby insure a regularity of spacing between letters or words, as hereinbefore referred to. The stop-pin 15 and the key (hereinafter more particularly referred to) are restored to their original position,when the latter is released by the operator, by the gravitative action of the weighted walkingbeam, as will be readily understood.

4:7 designatesa scale-bar, commonly known as the cylinder-scale and adapted to indicate the position of any particular character in the line, and said scale-bar is carried by uprights 48, extending down through slots 49 in the top plate 3 and riveted or otherwise secured to the arms 30 of the carriage-adjusting frame.

50 designates a rearwardly and upwardly projecting quadrant-shaped arm carried by the scale-bar, and 51 a forwardly and upwardly curved arm secured to the bar 29 of said frame at a suitable point, preferably near its center, and said arm is bent to inverted- U form to provide a downwardly-opening slot 52, and said U-shaped portion is bifurcated, as shown at 53, (see Fig. 1,) in order to pro vide a pair of guide-arms 5t, which extend below the mouth of the U-shaped slot 52 (see Fig. 2) and curve downwardly and forwardly.

55 designates a pair of hooks secured to the arched portions of the cross-bar 42 of the carriage, rearward of the bearingboxes 56, with which it is centrally provided.

In lieu of the customary cylinder and paper-feed mechanism employed in type-writing machines I provide a skeleton frame constructed as follows-that is to say: 57 designates an inverted-U-shaped casing of sheet metal and of slightly-greater length than a full line of printed characters and formed at its lower edges with the opposite grooves 58. Said casing contains a strip of soft rubber 59, which projects slightly below the upper sides of said grooves and exerts a downward pressure upon the hard-rubber platen 60, so as to holdits ribs or flanges 61,engaging the grooves of the casing, firmly down upon the lower sides of said grooves. By this arrangement it is obvious that the impact of the type against the platen is taken up by the strip of soft rubber,and consequently the sound deadened, and the impression is made perfectly legible, because the platen, in a degree, ac-

commodatesitself to the angle of the face of the type. The rubber strip 59 by exerting a constant pressure upon the platen prevents the latter from creeping, and is in turn held reliably in the casing by the end plates 62, secured to the latter by rivets or in any other suitable way. Said end plates are provided with outwardly-projecting trunnions 63 at their upper ends, which are journaled in the bearing-boxes 56 of the carriage and form the pivotal point or axis on which the platen and paper-feed mechanism swings, the axis of said trunnions coinciding with the center from which the curved arm 50, hereinbefore described, is struck, so that the return movement of the carriage, whether at either limit of its pivotal action (raised or lowered) or at any intermediate point, will result in the paper being fed to space for a new line by the contact of a part (hereinafter described) carried by the carriage with said curved arm.

6% designates arms which project rearwardly from the upper ends of the plates 62 and are limited in their upward movement by means of the overhanging hooks 55, (see Figs. 1 and 2,) which hooks therefore prevent the platen-carrying casing from swinging back beyond a vertical plane, as illustratedin Fig. 2, but leave it free to swing forwardly.

At a suitable point the arms 64 are con- H ated by a skeleton paper-guide frame 65, which extends downwardly and forwardly to a point contiguous to the rear lower edge of the platen (see Fig. 2) in order that the paper (indicated by the numeral 66) may be easily and quickly fed below the platen, the upwardly and forwardly sloping shoulders 67 upon the top plate and forward of the platen being adapted to deflect the paper up wardly and between the feed-

rollers

68 and 69, the former being mounted rigidly on the shaft 70, journaled in brackets 71, projecting forwardly from the casing 57, and provided at one end with ahand-button 72 for conveniently adjusting the paper by hand and at its opposite end with a small cog-wheel 73, meshing with the cog-teeth 74, formed internally of the ratchet-wheel 75,jonrnaled upon the trunnion 63 at the corresponding end of the machine, said ratchet-wheel being adapted, through instrumentalities hereinafter described, to feed the paper, and thereby form the space between lines.

The rollers 69 are mounted on a shaft 70, journaled in the sliding boxes 77, mounted in the bifurcated ends of the arms 71, retractile springs 78, attached at their opposite ends to said shafts 7O 76, holding the rollers 68 69 together with a pressure which accommodates itself to the thickness of the paper between the feed-rollers.

79 designates curved paper-guides, preferably three in number, which are carried by the rock-shaft 80, journaled at its opposite ends in the arms 81 of brackets 71, (see Fig. 0,) and said paper-guides extend concentrically of the axis of movement of the platen and terminate at their lower ends adjacent to the paper guides or deflectors 67 (see Fig. 2) in order to guide the front end of the paper upwardly between the feed-

rolls

68 and 69, after which the paper may be reliably adjusted or fed the required distance by means of the button 72, as hereinbefore explained, and projecting forwardly from the central paper-guide 79 is the index-finger 82, which, by its relation to the scale-bar, designates the aggregate number of character and word spacing keys which have been operated-that is to say, just how many steps the carriage has traveled. To still further facilitate the adjustment of the paper, one of the arms or guides 79 may be pivotally rocked, and its lower end thereby utilized asa lever for pushing forwardly against the shaft of the smaller feed-rollers to relieve the tension upon the paper, which therefore may be more easily and quickly adjusted.

83 designates a cylindrical sleeve riveted or otherwise secured to the outer end of the arm 81 adjacent to the ratchet-wheel 75, and said sleeve is provided with a longitudinal slot 84 in its upper side.

85 designates a sliding rod extending through the sleeve or box and provided at its opposite ends with the hand-button '86 and the head 87, and projecting upwardly from said rod and through said slot is a wedge 88, which is normally held at its innermost limit of adjustment, as illustrated most clearly in Fig. 7, by the expansion-spring 89, spirally encircling said rod and bearing at its opposite ends against the relatively stationary sleeve 83 and the head 87 and adapted to be compressed each time the carriage returns to its original or initial position for the starting of a new line by engagement with the curved arm 50, which, as hereinbefore explained, is

of such configuration that the headed end 87 of said rod will strike it irrespective of the position of the skeleton frameviz., the construction embodying the platen and the paper-feeding mechanism.

90 designates a fork or lever pivotally mounted upon the trunnion 63 at opposite sides of the ratchet-wheel 7 5, and 91 is an antifriction-roller, which is engaged by the sliding wedge 88, said roller having slight lateral play in order thatit shall remain in the proper position relative to said wedge when the fork or lever'90 is in pivotal operation. Said fork pivotally carries a gravity-pawl 92, which engages the ratchet-wheel 75, and is provided with a depending arm 93, and a retractile spring 90*, connecting said fork with the bracket 71, facilitates the return of the fork to its original position after each rotatable operation or adjustment of the ratchet-wheel. By this arrangement it is obvious that the movement of the wedge 88 in the direction indicated by the arrow a, Fig. 7, due to forceful contact of the head 87 with the arm 50, pivotally elevates the fork 90 and through the medium of the pawl 92 rotates the ratchet- In order that only a single space may be left between lines, a fork 94 is pivotally mounted between lugs 95, projecting fromthe inner end of sleeve 83, and to obtain sufficient'friction in this bearing to prevent the accidental adjustment of the fork I interpose between the same and said lugs ordinary friction-washers 96. When it is desired toleave only a single space between lines, this fork is thrown to the position shown most clearly in Fig. 7, where it will be noticed that it intercepts the path of movement of the head of rod 85, and consequently prevents said rod under the impact of arm 50 from sliding the wedge more than half-way past the roller 91, and as a re sult the pawl of the pivoted fork or lever is elevated only half the distance indicated in Fig. 5, and the ratchet-wheel is turned only a single step by the pawl. As the carriage begins a new line the sleeve 83 moves correspondingly, with the result that the wedge is withdrawn gradually from under the roller 91, and the fork or lever 90 settles back to its original-11. a, ahorizontal-position, (see Fig. 2,) the spring 89 atthe same time expanding as fast as the movement of the carriage away from the stationary arm 50 will permit until the wedge attains the relative position shown in Fig. 7. As the pivoted fork or lever 90 assumes its normal or horizontal position the dog 92, whose tendency at such time is to engage the ratchet-wheel through force of gravity, (see Fig. 1,) is thrown out of contact with the ratchet-wheel by reason of its arm 93 bearing down upon the spring-hook 97, projecting forward from sleeve 83, the force with which this arm bears down depending of course on the weight of' the fork or lever and the power of the spring 90, whose function is to facilitate the depression of said fork or lever, as hereinbefore explained. The disengagement, however, at this time of the dog and wheel is unimportant, as the latter is engaged frictionally and the paper prevented from creeping by the brake-roller 98 peripherally engaging said wheel and carried by the angle-lever 99, pivoted between the lugs of the sleeve 83, a spring 101, mounted upon the pivot of said lever, being utilized to hold the same in engagement with said wheel. -When necessary or desirable, however, to print at any intermediate point between the regular line-spacing intervals, it can be accomplished by throwing the spring-actuated brake-roller to the position shown in dotted lines, Fig. 5, where it is reliably held by the spring-hook 97 engaging the upper arm of the angle-lever 99; but in order to reliably hold the paper from creeping at this time I employ a friction-brake 103, secured to the lever 99 and thrown into engagement with the side of the spacing-wheel by the same 0peration which releases said wheel from the spring-actuated brake-roller. (See Figs. 5 and 8.) When it is desired to resume printing along the regulation spacing-lines, the roller and the dog are thrown back into engagement with the ratchet or spacing wheel, as will be readily understood.

101 designates the shaft upon which the lower ribbon-spool 105 is mounted, and said spool is ratchet-toothed in one edge and is engaged by a gravity-dog 106 to prevent back rotation. It is also engaged by the actuatingdog 107, pivotally mounted upon the arm 108 of shaft 19 in order that the depression of arm 18 to operate the walking-beam shall be accompanied byan adjustment of the ribbon 109. Said ribbon extends upwardly from the spool 105 through the slot 110 in the top plate, thence horizontally forward and through the vertical arms 112 of a slide-plate 111 upon the top plate 3 and below a guide 113 secured to the top plate, thence upwardly and over a second guide 111- and through a verticallyslotted guide or fork 115, which gives the ribbon a quarter-turn in order that it may be wound properly upon a horizontal spool 116, journaled upon the stub-shaft 117, projecting upwardly from the top plate 3, as shown most clearly in Figs. 1 and 2. This ribbon in its span between the arms 112 of plate 111 bridges the opening 118, through which the type operate, and in order that the type, should they become loose or uneven through wear or any other cause, may strike the ribbon always at the proper point said opening is guarded at either side by the up wardly-converging guide-wings or deflectors 119, said wings being pivotally connected, as at 120, with brackets secured to the top plate and pressed toward each other by springs 121, secured to said brackets. In case a type should strike either of these wings at such an angle that the wing must yield or the type be injured the former will swing outwardly at its lower end, but remain practically stationary at its upper end, and thus permit the type to continue upward, but at the same time insure that it strikes the ribbon at the proper point, as will be readily understood by reference to Fig. 18. The sliding plate 111 is employed for the purpose of automatically withdrawing the ribbon from its position over the type-opening 118 when the obliteratingkey, hereinafter described, is operated.

122 designates a shaft journaled in the side flanges of the bed-plate and provided with an upwardly-projecting arm 123 and forwardlyprojecting key-levers 124E. Said key-levers carry vertical rods 125 at their front ends, extending up through the keyboard-frame 126, and mounted upon said rods are, in this instance, preferably two word-spacing keys 127. Rearward of said shaft, suitably journaled and preferably in the same horizontal plane, are a series of shafts 128, each being provided for its full length with a slot 129 and with an upwardly-projecting arm 130, said arms, and

likewise the arm 123, being connected pivotally by tie-rods 131 with the movable rod 21 of the swinging frame. The said tie-rods at their points of connection with the rod 21 are longitudinallyslotted, as shown at 132, in order that either of said tie-rods may be caused to swing said frame forwardly without affecting the position of the remaining tie-rods, as will be readily understood by reference particularly to Fig. 19.

Mounted upon the shafts 128 are the character'key levers 133, and said levers carry pivotally at their front ends the vertical rods 134, surmounted by the character-keys 135, said rods extending up through the keyboardframe 126. Said character-key levers loosely encircle said shafts and are each provided with a tooth or lug 136, projecting into the slot 129 of the corresponding shaft, said teeth or lugs being narrower than said slots and normally resting upon or against the shoulder at the lower edge of the slot in order that when one key is depressed the shaft may be operated the requisite distance to cause the operation of the swinging frame 21 without affecting the position of any of the other levers upon said shaft. As this construction and arrangement is substantially the samewas that illustrated and described in my former patent referred to, it is thought a more minute description than the foregoing is unnecessary, it being understood, of course, that the weight 16 is relied upon, with the assistance of spring 22, to return the keys to their normal or elevated position.

In order that a novice may replace a defective or broken type-lever without any possibility of disturbing the alinemcnt of the type, and in order to limit the upward movement of each type-lever, so as to prevent an unnecessarily heavy stroke upon the ribbon, I provide the following construction-that is to say: 137 designates a horizontal plate curved concentricallyof the center of the opening 118 in the top plate through which the type 0perate. It is secured to the under side of the top plate 3 by means of screw-bolts 138 and is provided at its inner or rear edge with a depending rib or flange 139 and at its front edge with radially-arranged depending hookarms 1 10, said hook-arms being arranged a suitable distance apart and in number exceeding by one the type-levers 141 arranged between them, said type-levers being provided with fixed pivots or trunnions 142, which find a hearing in said hook-arms.

143 designates a segmental plate, which is secured upon the top plate by the screws 138 (see Fig. 11) and is provided with the depend ing radial arms 144, which form the upper hearings or caps for the type-bar trunnions, and thus maintain them in proper alinement, as will be readily understood.

To remove a type-bar, it is only necessary to withdraw screws 138 from the plate 143, remove the latter, lift the type-bar from the hook-arm, replace it with another, and rose- IIO cure the plate 143 in position. To facilitate this operation, plate 143 may be made in sections, so that it will be unnecessary to withdraw all of the screws 138. The heels of said type-levers are linked in the customary manner by the tie-rods 145 to the character-key levers 133, (see Fig. 1,) and each type-bar carries three type 146, preferably of integral construction, the platen determining by its position which of the three shall strike the paper. When the platen occupies its normal or central position, the middle or small-letter type will strike the paper. When it is moved forward or toward the operator, the capital letters by preference will strike the paper, and when it is moved rearward or over the type farthest from the operator the numbers or symbols of punctuation will be printed. The position of the carriage-adjusting frame, and consequently of the platen, is determined by means of two shift-keys 147 and 148, both being carried by levers 149, journaled upon the shaft 122. The lever of key 147 carries an arm 150, which is pivotally connected by the tie-rod 151 to the lower end of an arm 152 of the horizontal rock-shaft 153, said rockshaft being journaled in brackets 154, secured to the back plate of the machine. 155 designates a similar rock-arm near the opposite end of said shaft, and both rock-arms are provided with slots 156, engaging the pins 37 of the carriage-adj ustingframe, (see Fig. 2,) said slots being provided for an obvious purpose.

157 designates brackets which carry the rock-arm 158, pivotally connected at its upper end to the lower end of rock-arm 155 and at its lower end to the tie-rod 159, said tie-rod being connected at its front end to the arm of the key-lever of the shift-key 148. By this arrangement it is obvious that the depression of the shift-key 147 causes the carriage to'move rearwardly against the resistance of the rearmost springs 36, so as to dispose the platen over the type 146 farthest from the operator, and that when said keyis released said compressed springs return the carriage to its original position. To move the carriage forwardly from its center, the key 148 is depressed. This operation obviously swings forward the upper ends of the rockarms 152 against the resistance of the foremost springs 36, which return the carriage to its original or central position when said shiftkey is released.

With each depression of a character or word-spacing key the swinging frame is operated and in turn by lifting the weight end of the walking-beam causes dog 15 to rotate the wheel or drum 5 in the direction indicated by the arrow, Fig. 3, this movement of the wheel or drum of course causing the carriage to travel one step toward the left, because connected to the wheel or drum by the cable 5 in the manner hereinbefore explained. The same movement of the swinging frame also causes the dog 107 (see Fig. 2) to rotate the lower ribbon-spool and move the ribbon one step. The advance of the carriage is resisted by the carriage-returning spring 160, coiled around and secured at its inner end to the hub of wheel 5 in any suitable manner and secured at its outer end to a pin 161, projecting forwardly from the back plate. The

depression of a character-key also synchronously operates a type-bar, which, however, does not strike the paper until the carriage and ribbon movements have ceased. This is accomplished because the arm 18 strikes the stop-pin 23, and thereby controls the movement of said dogs, while the key is permitted to continue its downward movement by reason of the fact that the spring 22 expands and permits the swinging frame 21 to move after the operation of said dogs has ceased. As a result all possibility of the work being blurred is obviated and the letters and words are properly spaced, because momentum or reactionary movement of the carriage is prevented by means of the locking-pin 45, engaging the gage-bar 44.

To return the carriage to its original or initial position at any time,l have provided a separate key 162,secured at the front end of the angle-lever 163, mounted pivotally upon the pin 164, projecting from theside of the machine, and said key is held elevated normally by means of the retractile spring 165, connecting the upwardly-projecting arm of the angle-lever with a fixed pin 166, and said arm is also connected pivotally by a link 167 to the depending arm 168 of a rock-shaft 169, said'rock-shaft being journaled in a bearingstandard 170, secured to the bedplate of the machine. (See Fig. 3.) Said rock-shaft is also provided with a rearwardly-projecting arm 171, connected by a tie-rod 172 with a gravity-dog 173, pivoted, as at 174, to the back plate of the machine. Said dog engages the notches of wheel 5 to prevent back rotation of the same by spring as the dog 15 is disengaged from the wheel after each adjustment of the carriage. Said dog 173 is so arranged that under the depression of the carriage-release key 162 it trips dog 15that is to say, throws dog 15 in the direction indicated by the arrow-and permits the spring 160 to return the carriage to its original position. A stop-pin 175, projecting from the back plate, limits the outward movement of both dogs, so that immediately the key is released they gravitate back into engagement with the Wheel. The spring 165, which reelevates the key, obviously facilitates the rengagement of dog 173 with the Wheel. Each time the carriage-release key is operated the spring 160, as explained, returns the carriage to its initial position, and each time this operation takes place, as also hereinbefore explained, the slide-rod 85 is operated by striking against the arm 50 and the wedge causes the automatic rotation of the feed-rollers and the consequent adjustment of the paper to provide a single space between the lines if the fork 94 occupies the position illustrated or a double space between lines it said fork is thrown. out of the path of the headed rod 85 in the direction indicated by the arrow at, Fig. 7.

176 designates a key which through instrumentalities to be presently described is adapted to swing the platen and the paper-feed mechanism, with trunnions 63 as the axis or center of motion, as hereinbefore explained, to the position shown in Fig. at in order to expose the characters last printed. The said key is mounted upon the vertical rod 177, ex-

tending through the keyboard-frame and the bed-plate of the machine and pivotally connected to the front end of the roclelever 178, and said lever is pivotally connected to the front end of a second and preferably longer rock-lever179, the latter being connected by a tie-rod or cable 1 S0 with the vertically-swinging arm 181, pivoted to a bracket 182, projecting from the back plate and held normally elevated by spring 181.

183 is a rod connecting the rear ends of arms 64 of the skeleton frame carrying the platen and feed-roller mechanism,and mounted loosely and slidingly upon said rod is a disk 18%, connected by a cable 185 to the swinging arm 181, said cable being guided through an opening 186 of the top plate by the grooved roller 18?, journaled in bracket 188, depending from the top plate, said roller being located close by the side of the typeopening 118 of the top plate in order that the depression of the key 186 may swing the skeleton frame a full quarter ofa circle. (See Figs. 2 and a.)

In order that the sliding disk 184 may retain its proper relation to the roller 187 as the carriage travels laterally in one direction or the other, it fits normally in the bifurcation 53 of bracket 51 of the carriage-ac'ljusting frame. (See Fig. 1.) In this position it is obvious that the sliding or longitudinal movementof the carriagerod183, upon which the said disk is mounted, does not change the position of said disk in the least, and it is clearlyobvious that the disk cannot slide upon said red when disengaged from the arm 51 by the depression of key 176, (see Fig. 4,) be cause practically the entire weight of the skeleton frame, the platen, and the paperfeed mechanism is sustained by the cable 185, which therefore holds the disk with considerable pressure upon said rod. The tension of said cable continues as the key is depressed until the disk reenters the bifurcation of said arm 51. By this construction it is obvious that the carriage may be elevated for the inspection of the work as quickly as a character-key can be operated, because the skeleton frame and the bars carried thereby are of extremely light weight, being composed in the main of aluminium, and because the connections give the operator considerable leverage. The weight of said parts returns them instantly to their original position and the hooks 55 of the carriageframc prevent the platen from swinging rearwardly beyond a vertical plane, as hereinbefore explained.

The carriage of the machine is adapted to make sixty steps in traveling from its initial position to its utmost limit of travel, and the wheel 5 in this instance is provided with sixty-five notches, numbered consecutively, as per dial, the zero and sixty-fifth notches being identical, and the number of spaces in a line which the carriage may take-that is, the length of the lineis determined, as hereinbefore explained, by the relative positions of the indicator-hand 11 and the Wheel-that is to say, if the indicator-hand has its tooth 14 engaging the notch numbered 30 (see Fig. 3) the carriage will make just thirty steps audit necessaryor desirable a few extra steps in order that a word or syllable may be completed, and thus leave no broken syllables at the end of the line. lVhen the carriage occupies its initial position and it is desired to print a full line, the zero or sixty-fifth notch of the dial is about vertically below its axis and the tooth of the index-finger is engaged with the fifty-fifth notch of the dial, as shown clearly in Fig. 1 1, this engagement being accomplished in a manner hereinafter explained. The carriage may now be advanced by the manipulation of the type and wordspacing keys until it has taken fifty-seven stepsthat is to say, until the number 55 of the dial assumes a position two steps beyond the vertical plane of the axis of the dial, at which time it is arrested by what I term the first stop-pin 189, projecting from the back of the frame. This is the normal length of the line; but a few extra steps-viz., in this instance, three may be taken in order to complete a word or a syllable, as hereinbetore explained, and when said extra steps have been taken, making a total of sixty steps, the lug 13 of the index-hand occupies the position shown-in Fig. l5- t-hat is to say, bears against the stop-pin 190, projecting from the back plate 2. After the lug has attained this position if it be desired to vary the length of the next and succeeding lines it can be accomplished by means of the lever 191, pivoted to the back plate to the right of pin 190 and provided with a beveled tooth or wedge 192. For convenience of operation said lever is provided with an arm 103, projecting rearwardly through a slot 191 of the back plate, which may be depressed by the operator to cause the beveled tooth or Wedge 1.)2 to move upwardly and by engagement with the rear side of lug 13 or its tooth l4 swing indicatorhand 11 outwardly from engagement with the whee l5,as indicated by dotted lines. The operator then manipulates the carriagerelease key and permits the spring to move the carriage toward its initial position, the dial rotating at the same time in the direction opposite to that indicated by the arrow, Fig. 3. When the number on the dial which represents the number of steps desired to be taken in the new line comes opposite the index-finger 12,

the lever 191 is thrown to its original position to permit the tooth 14 of the indicator-hand to rengage the notch of the wheel corresponding to said number. To render this operation positive and reliable, however, it is essential or desirable that the operator grasp the carriage and restrain the spring from returning it too rapidly. By so doing when the desired number of the dial comes opposite the indeX-finger 12 the carriage may be held stationary until the lever 191 is disengaged from the indicator-hand, as will be readily understood.

To bring out more clearly the fact that the dial only makes sixty steps, leaving five teeth, therefore, practically blank, the lever 191 is arranged so that its hub apparently prevents the indicator-hand 11 from traveling farther in the direction indicated by the arrow, Fig. 3; but in reality this lever does not come in contact with the lug of said hand, because the return of the carriage to its initial position determines the movement of the indicator arm in the direction indicated. This is made evident when it is remembered that the engagement of the lug 14 of said arm with the notch 30 of the dial-wheel permits of a line being printed of only thirty steps and three extra steps, if desired. In other Words, this mechanism determines not Where the line of printingbegins, but where it ends. To illustrate further, if the indicator-hand registers with notch 10 of the dial-wheel (see Fig. 14) a line of only ten steps, with three extra steps, if desired, can be made.

Referring now particularly to the means for preventing the movement of the carriage beyond a certain point and the depression of the keys after the carriage has reached such point, 195 designates a lever which is pivoted a short distance from its upper end upon a headed pin 196, projecting from the back plate of the machine and pressed normally against said back plate and in the path of lug 13 (see Figs. 2 and 3) by means of a spiral spring 197, coiled around the pivot and interposed between its head and the lever. To hold said lever normally in a vertical position, I preferably provide a weight 198 at its lower end, and pivotally connected to said end is a slide-bar 199, fitting between the guide-ribs 28 of the supporting-arm 27 of stop-pin 23 and adapted by the power of the indicator-hand when moving in the direction indicated by the arrow 6, Fig. 3, to be projected through the slot 25 of said stop-pin, the movementof said lever being limited by contact with the stop-pin 189. The relevation of the character or word-spacing key which was instrumental in its depression in moving the carriage the last step taken, and consequently in projecting the sliding bar 199 through the slot 25 of stop-pin 23, causes, through the medium of the swinging frame 21, the advancement or projection of the sliding hook 200 through the slot 24 of said stop-pin, and said hook, by reason of the .ing-key 201.

Supposing now that one, two, or three extra I characters are necessary to complete the formation of a word or a syllable or to round out a line, said extra characters may be printed by the operation of what I term the unlock- This key is mounted upon the vertical rod 202, suitably guided and mounted upon the front end of a bell-crank lever 203, pivoted, as at 204, to the bed-plate or brackets depending therefrom and having one arm extending vertically upward through a slot 205 in the bed-plate, adjacent to the back wall of the frame, said arm being forked at its upper end, so as to embrace the opposite sides of the hub portion of the lever 195, and said forked end is longitudinally slotted and pivotally mounted upon pins or trunnions 206, projecting laterally from the hub of said 1ever, as shown clearly in dotted lines, Fig. 2. It will thus be seen that the depression of said key forces the lever 195 forwardly against the resistance of spring 197 until it is moved out of the path of the lug 13 of indicator-hand 11, and while held in this adjustable position extra characters may be printed until the lug strikes the second stop-pin 190, which limits the movement of the carriage, and consequently of said hand. To return the carriage to its original position, the key 201 should continue depressed and the carriage-release key 162 manipulated as hereinbefore explained.

207 designates a bell secured to the back plate at a suitable point, and 208 a pin, projecting also from the back plate, upon which the spring-metal arm of the bell-clapper 209 is pivotally mounted, a pin 210 being employed as a balance for said arm in order that the clapper may be elevated after contact, and thus permit the bell to, emit a clear and noticeable sound.

211 designates an extensiomarm which is forked at its lower end, so as to provide the lower and upper arms 212 and 213, respectively, and is pivoted between said arms to the upper end of the bell-clapper arm, so as to work in a vertical plane. The arm 212 is of such length and form that it engages the underside of the bell-clapper arm forward of the pivotal point of the latter with said eX- tension-arm, and thereby holds the latter in longitudinal alinement with said bell-clapper arm, so that as the extension-arm is depressed the pressure of the forward end of projecting arm 212 against the under side of the bellclapperarm imparts a corresponding move.- ment to the latter, and thereby raises the clapper up from the bell, this operation being effected by the indicator-hand 11 asitrotates in the direction indicated by the arrow 1), Fig. As the indicator-hand releases the extension-arm the weight of the bell-clapper arm causes it to descend and raise the exten si0n-arm to its original position, the bellclapper in such descent striking the bell, as will be readily understood. When the indicator-hand rotates back to its original position, it strikes the extension-arm 211 from below, and in order to prevent the latter from being thrown pivotally outward beyond its center of gravity, and therefore outward ol' the path of the index-hand when next it moves in the direction indicated by the arrow, the extension-arm is provided with an upper arm 213, which strikes against the upper side of the bell-clapper arm forward of the pivotal point of the latter with the extension-arm before the latter attains a perpendicular position, and thereby insures the return of said arm to its proper position namely, in longitudinal alinement with the bell-clapper arm and in the path of the in- (1BXl1ftl1d,SO that the latter at the proper time may again operate the bell-clapper and sound the alarm in the manner explained. By this arrangement it will be seen that the bell will always ring just before the normal length of line is completed-that is to say, will ring if the line is sufliciently long to require the indicator-hand to be set at least eight steps in advance of a point vertically below its axis of rotation.

"As frequently happens, an operator strikes the wrong key, and thereby prints at character which it requires time and trouble to neatly erase. To accomplish this with as little time as it takes to print a character, I have provided what 1 term an obliteratingkey mechanism. The keyis numbered 21st (see Figs. 1 and 9) and is mounted upon the upper end of a suitably-guided rod 215, pivotally carried at the front end of a lever 216, fulerumed in a bracket 217, depending from the bed-plate of the machine, and said lever is connected by a tiered 218 to the heel of a type-bar 219, which differs in construction from the regular type-bars in that it is bifurcated at its lower end, as at 220, and carries pivotally in said bifurcated end a semi cogwheel 221, provided with a centrally and oppositely projecting stem 222, narrowed or channeled out at one side, as at 222, which projects horizontally forward when the typebar is vertically pendent and engages the ink-pad 223, this pad being adapted to apply ink to the end of the stem 222 of the same color as the paper upon which the characters are printed-that is to say, if white paper is used the ink will be white, or substantially so. If blue paper or any other color of paper is employed, the pad will supply ink of the corresponding color. This pad is provided with a hook 224:, which hooks into the loop plate clamped by plate 226 to the upright post 227, supporting the plate 137 at its center, so as to relieve the top plate of the machine of the weight of the type-bar mechanism. Said loop-plate is provided with a segmental rack-arm 228, extending concentrically of the axis of type-bar 219 and provided with teeth corresponding in number to the teeth of the semi cog-wheel 221, and the pin 229, projecting partly across the bifurcated portion of the type-bar 219 above the cog'pivot, limits the rotatable movement of said semi cog-wheel when it is rotated in one direction or the other. (SeeFig. 13.) \Vhen the key 21 1 is depressed, the type-bar is thrown upward, and the engagement of the semi cog-wheel with the rack-bar causes the former to rotate a half-circle in the direction indicated by the arrow 0, Fig. 9, and assunie the position shown in dotted lines, the ink stamp or stem 222 maintaining the position to which it is adjusted by the pressure ex erted by the friction-washers 230, interposed between said stamp and the branch arms of the top plate. The stamp or stem of said semi cog-wheel swings freely through the bifurcated portion of the type-bar, because it is narrowed or cut away at one side, as ex plained, in order to avoid contact with the pin 229, which, however, reliably limits the rotatable movement of said stamp to one hundred and eighty degrees, so that it shall at one extreme (see dotted lines, Fig. 9) be in position to strike the paper upon which the characters are printed and in the other extreme be in position to strike squarely against the ink-pad 223, as shown in full lines, Figs. 2and 9. Before this stamp can strike the paper it is necessary that the interposed ribbon be shifted to one side, as hereinbefore stated, and to accomplish this purpose the type-bar 219 is connected by a link 231 with the sliding bar 232, having a screw 233 engaging the slot in the top plate to hold it in position, and said slide-plate is pivotally connected by a bell-crank lever 235, mounted at the under side of the top plate, as at 236, with the depending pin 237 of the ribbonsupporting plate 111, hereinbefore described, so that as the key 214 is depressed the typebar 219 through the instrumentalities just described will slide the plate 211 from the position shown in full to the position shown in dotted lines, Fig. 10, and consequently shift the ribbon from over the opening 118 and permit the stamp 222 to come in direct contact with the paper, and by applying a coating of ink upon the character printed by mistake completely hide the same from view and leave the paper in proper condition to instantly receive a new imprint at the same identical point. As the key is released the type-bar resumes its original position and the stamp is reinked by contact with the pad. At the same time the ribbon is shifted back to its original position over the opening 118, this operation being made positive and reliable by the employment of a spring 238,

mounted upon the trunnions of the type-bar and bearing at its opposite ends against the latter and the arms 144.

A recapitulation of the complete operation is believed to be unnecessary, as the functions of the various parts have been set forth, and it is to be understood, of course, that changes which do not involve a departure from the spirit and scope of the invention may be resorted to.
