SPECIFICATION forming part of Letters Patent No. 749,001, dated January 5, 1904.

' Application filed March 9,1899. smart. 708,423. (No model.)

To all whom iii-may concern.-

Be it known that'I, OLUF TYBERG, a citizen of the United States, residing in the borough of Brooklyn, city of New York, State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

In my application,filed May 8, 1897, Serial No. 635,681, I have shown and. claimed a broadly novel organization wherein a wheel continuously revolving about a normally stationary axis has when desired imparted to it a diametrical bodily motion in a direction opposite to that in which is traveling the character thereon which has been selected to be printed from. The resultant'of this composite motion is that the character on the wheel is momentarily maintained at the printing-point, and during that time an impression is taken therefrom. The machine herein described operates upon the same principle; and my present invention comprehends new and useful ways of controlling the operation of the continuously-revolving typewheel, taking impressions therefrom, and effecting the required operations in a typewriting machine.

In the accompanying drawings, Figure l is a plan View; Fig. 2, a rear elevation on a somewhat larger scale with parts of the pa-.

per-roll and carriage broken away; Fig. 3,- an end elevation looking at the right-hand end of Fig. 2; Fig. 4, a detail vertical sectional view on the line 4 4 of Fig. 2; Fig. 5, a vertical transverse section through the machine on the line 5 5 of Fig.1; Fig. 6, a detail sectional-view on the same line as Fig. 5, showing some parts of that figure in a different position; Fig. 7, a horizontal section on the line7 7, Fig. 3; Fig. 8, a detailed horizontal section taken on an irregular line below the plane of section of Fig. 7 and showing merely the type-wheel shaft and some of the parts associated therewith. Fig. 9 is a longitudinal section through the paper-roll and certain parts associated therewith; Fig. 10, an end elevation looking at the righthand end of the machine, showing the paperroll, its carriage, and some associated parts; Fig. 11, an elevation of the face Of-the hand wheel locatedat the left-hand end of the paper-roll Fig. 12, a section through Fig. 11 on the line 12-12; Fig. 13, a diagram view showing the movement of the type-wheel.

The frame of the machine may be of any appropriate form, and the construction shown need not be referred to except as it may seem desirable in connection with the description of operative parts of the mechanism.

I prefer to employ a rotary driver and have therefore shown a'cammed, ribbed, or toothed driving-cylinder 1, appropriately mounted in bearings in the side plates of the machine,

located somewhat above and in rear of the bank of keys. This cylindrical driver may be continuously rotated in any suitable manner. In the drawings I have shown a shaft 2 arranged parallel with the driver and having on one end a grooved pulley 3 and on the other end a beveled pinion 4. The grooved pulley may receive a band from any suitable motoras, for instance, a treadle mechanism, a spring-motor or electric or other motor mounted upon the stand upon which the machine is placed, or a suitable motor, as an electric motor, may be located at the end of the shaft 2 and the armature thereof mounted thereon. The power means, however, for rotating the driver and the type-wheel form no part of this invention.

The beveled pinion 4, Fig. 3, meshes with a corresponding beveled gear 5 on the lower end of a short vertical shaft 6, which carries a spiral pinion 7, gearing with a spiral gearwheel 8 upon the shaft or trunnion of the cylindrical driver 1. The shaft 6 carries also a toothed gear 9, that meshes with a toothed wheel 10 on the vertical type-wheel shaft 11, with which the type-wheel 12 revolves. When power is applied to the shaft 2, the driver 1 and the typewheel are therefore continuously rotated at appropriate relative speeds. The type-wheel shaft has its upper bearing 13 on a flat bar, or plate 14, capable of rocking upon an axis 15 out of line with the axis of the type-wheel shaft. The lower end of the type-wheel shaft has its hearings in a similar bar or plate 16, capable of turning upon an axis 17, coincident with the axis 15 of the upper plate 14.

The type-wheel may have several circumferential lines or series of characters. Two are shown, and the wheel should therefore be capable of assuming at the will of the op erator either of two positions. I have shown the type-wheel as carried by a sleeve 18, Figs. 3 and 4, of enlarged diameter, at its lower end, thus forming an annular shoulder 19, that rests upon a collar 20, keyed to the typewheel shaft. Below this shoulder the sleeve is slotted, and a lug 21 on the collar.20 occupies the slot. In the normal position with the shoulder 19 resting on the collar 20 the upper series of characters on the face of the type-Wheel is in the plane of printing. When the type-wheel and its sleeve are elevated as hereinafter described, the lower series of characters on the face of the wheel is brought 1 into the plane of printing. The shoulder 19 determines the normal lower position of the wheel, and a stop 221, shown as a roller mounted in bearings in an arm depending from the frame and against which the side of the type-wheel may abut, determines the upper position of the wheel. The type wheel rotates continuously in the direction of the arrow, Figs. 1 and 3. The driver rotates continuously in the direction of the arrow, Figs. 3 and 5.

A vertical shaft 22, Figs. 3, 7, and 8, parallel with the type-wheel shaft, is mounted in suitable bearings, and arms 23 24, projecting radially therefrom, are operatively connected with the plates 14 and 16as, for instance, in the manner shown in Fig. 8, where a pin on the plate 16 lies in a slot in the arm 24. The connection between the arm 23 and the upper plate 14 may be made in the same manner. The type wheel and associated parts are contained in a box or compartment located at the left-hand end of the frame.

The face of the type-wheel is divided into the required number of equal spaces. All of the said spaces except one are occupied by the characters in the two series of characters shown on the wheel, the characters of one series being respectively exactly opposite the characters in the other series. The remaining space is left blank. Fast on the typewheel shaft below the type-wheel is a ratchetwheel 25, Figs. 3 and 7, of the same diameter as the type-wheel and having teeth equal in number to the spaces into which the face of the type wheel is divided. The point of each toothof the wheel 25 is the same distance from the axis of the type-wheel shaft as is the face of the corresponding character on the type-wheel and in a line that divides the face of said character centrally. These proportions or arrangements I prefer as giving the most perfect results. A lever 26, pivoted on the frame at 27 and normally held away from the ratchet-wheel 25 by its spring 28, is adapted to engage its teeth when actuated as hereinafter described. When the lever 25 is thrown into engagement with a tooth of the ratchet, the obstruction it opposes to the normal revolution of the wheel about its center will cause the plates 14 16 to swing upon their center and carry the axis of the type-wheel through the are indicated by the solid arrow in Fig. 8, where the dotted arrow indicates the direction of rotation of the type-wheel. Referring to the diagram view, Fig. 13, the axis on which the plates 14 16 swing is indicated by 15 17. The axis of the type-wheel in its normal position is indicated by a, and the same axis in another position to which it will be moved by the swinging plates 14 16 is indicated by b. The dotted line connecting the points marked a and 1) indicates the are through which the typewheel shaft may be swung. The type-wheel with its axis in the position indicated by a is represented by the solid circle 0, while the same wheel with its axis in position indicated by b is indicated by the circle d, while the same wheel with its axis in a position midway between the points a b is indicated by the circle e. The shape or relation of the end of the lever 26 to the teeth of the wheel 25 is preferably such that when the wheel is arrested by the lever the point of the tooth which the lever engages is held at rest at a point, as y, Fig. 13, in a line no, extending from the axis of the plates 14 16 and equally bisecting the are described by the type-wheel shaft in moving from the position a, to the position b, which point is the point of intersection of the two circles representing the type-wheel and described, respectively, from the centers at b. It will therefore be apparent that the point of the ratchet-tooth engaged by the lever 26 will be held at rest so far as its circumferential movement is concerned and that the corresponding character on the type-wheel will similarly be held at rest at the printing point, while an impression may be taken therefrom without, in fact, arresting the rotation of the typewheel about its center. be the same if the axis of the typewheel were moved in a straight line represented by the cord of the are a b or if the plates 14 16 were so pivoted as that the curve of the are a b were reversed. If the movement were in a straight line and were equal and opposite to the movement of the typewheel about its axis, the point upon the type-wheel to be printed from would be stationary both as regards it circumferential movement and also as regards radial movement. If the curve of the arc of movement of the type-wheel shaft is as indicated in Fig. 13, the point will have a slight radial movement away from the axis 15 17 along the line at, this movement being represented by the distance between the point y and the circle e, and if the pivots of the parts 14 16 were so located that the curve of the are a I) would be reversed then there would be a slight radial movement toward the axis 15 17. To restate this matter in another Way,it may be said that the movement bodily of the type-wheel is opposite indirection to the direction of rotation of the rear or impression face of the type-wheel, and consequently a given point upon the rear face of the type- The action would wheel which by the rotation of the wheel' about its axis would be carried past the printing-point at a uniform speed remains at that point for a moment, because the bodily motion of the type-wheel gives to said point upon the rear face of the wheel a motion equal and opposite to that which said point receives by reason of the rotation of the wheel about its axis.. By placing the type-wheel on a vertical shaft I am enabled to place the ratchet-wheel 25-of the-same diameter below it and below the carriage and obtain room for the lever 26. r

The means-I have shown of operating the lever 26' to cause its-engagement with the ratchet-wheel 25 are controlled by the fingerkeys and are of course of such character that upon'the depression of a given key the tooth in the ratchet that will be then engaged by the end of the lever 26 is such as to cause the character on the wheel corresponding with the key depressed to remain at the printing-point.

adjacentto the bottom plate of the frame and are appropriately fulcrumed upon knifeedges 30 and guided. in slots or guideways formed in some of the frame-plates. The

spacing-key 31 is elongated and located in' front ofthe bank of fingerkeys, as usual, and is connected at each end by a lever 32 to a rock-shaft 33, mounted in bearings beneath the bottom plate of the machine and from which an arm 34 extends rearwardly to approximately the same distance as do the le-' vers 29 of the other'keys.

In that embodiment of my invention which the drawings illustrate the continuously-rotating driver 1 is provided with two spiral series of cams, ribs, or projections 35, a given projection 35 in one series being immediately opposite a corresponding projection in the other series, and there are in each series as many cams or projections asthe number of spaces into which the face of the type-wheel is divided. The type-wheel is geared to make two revolutions to one of the driver, and consequently each space on the type-wheel has two corresponding projections on the driver appropriately located to effect the operation hereinafter described. Other relative speeds of rotation of the driver and type-wheel may be adopted and cams or projections on the driver appropriately arranged therefor. In front of the driver on a fixed shaft 36 are mounted a series ofindependently-revoluble wheels 37,-each in line with a pair of projections 35 on the driver and each having teeth 38 five such teeth'being shown. The relation of each toothed wheel 37 to its operating cams or projections 35 on the driver is such that the wheel may occupy either the normal position, in which the projections on the driver do not come in contact with a tooth on tions will in their revolution engage a tooth leveriin its normal elevated position.

the wheel by a spring 46.

able push-pin 39,- preferably flat and adapted to slide vertically in a guide in the frame. Itsenlarged lower end is slotted and seated upon a pin or rod 40, extending through the slotted cross-piece 41 of the frame. A flat spring 42, mounted upon a cross-piece of the frame, presses upon the upper edge of the enlarged end of -the vertically-sliding pin and holds it normally in its lowest position, thus pressing down the inner end of the finger-key lever and maintaining the outer end of the This spring also serves to return the vertical rod to its normal position after it has been rocked r'earwardly, as hereinafter described. On the opposite'side of the enlarged end of each vertically-sliding pin is a projection 43, adapted .to engage-a cross-platez44 and limit the up- The key-levers 29 are arranged horizontally ward movement'of the rod when elevated by the depression of the finger-key. Normally the upper end of the rod 39 is in contact with one of the teeth ofits corresponding wheel 37. v If now a finger-key be depressed to any extent, the corresponding vertically-sliding pin 39 moves upwardly and partially turns its wheel 37.

To insure pawl or latch 45, normally'pressed toward At the end of this latch there is a slight projection having a short inclined face next the pivot of the latch and a longer inclined face 47 forming the end of the latch. Normally a tooth 38 upon the wheel 37 is in engagement with the short inclined face, which serves to hold the wheel in the normal position. When the wheel is moved by the pin 39, the tooth in engagement with the latch rides past the angle formed by the two inclined faces thereof and the longer inclined face 47 acts upon the tooth to bring and hold the wheel in proper position to have a tooth engaged by one of the projections on the continuously-revolving driver. It will thus be apparent that the wheel is brought to the proper position each time that the key-lever is depressed, even though but a partial depression of the keylever occurs or the movement of the rod 39 is not made of suflicient extent to turn the wheel'37 the required distance. The projection 35 engages the tooth now lying in its The wheel, however, is to be turned sufficiently far'to bring a tooth thereon into the path of the projection 35 on the continuously-revolving driver 1. this, I provide for each wheel 37 a pivoted path, Fig. 6, and moves the wheel 37 through a partial revolution.

35 on the revolving driver has carried the tooth of the wheel 37 with which it is in engagement into such position that the projection-35 passes out of engagementwith it, one of the teeth of the wheel comes against the When the projection short incline of the latch 45 and the wheel isv again held at rest in its normal position. The arm 34 of the spacing-key 31 may operate upon a similar verticallysliding rod, which is elongated, as indicated by dotted lines 48 in Fig. 5, to extend through the bedplate and into contact with the arm 34. The operation of spacing will be referred to later. During the partial rotation of the toothed wheel by thedriver the tooth thereof following that with which the push-pin 39 was in engagement before the movement commenced will strike against said pin and rock it rearwardly, this being permitted by the spring 42, which by its reaction returns it to the normal position immediately in rear of said tooth, Fig. 5, the wheel now' being at rest again andheld by the latch or pawl 45. Above the series of wheels37 'is a cross-bar 49,whose bottom is transversely slotted in line with each wheel and formed with a longitudinal channel or groove in its under'face. A bolt or rod 50 occupies this channel, and in each slot is a lever 51, pivotedon-the rod 50. One end of each lever 51 is normally thrown down so as to be engaged andlifted by a tooth on its corresponding toothed wheel 37 when that wheel is partially rotated-by the driver, as already described. Its opposite end normally bears against a plate 52, which lies under the upper ends of all the levers 51 and is preferably inclined in the direction of its width from the rear downward toward the front of the machine. This plate is carried by three arms 53, one connected with the plate near each end and one about its middle and all rocking upon a transverse shaft 54. The downwardly-projecting arm 55, carried by the central one of the rocking arms 53, lies against the free end of the rocking 1ever26, pivoted at 27, Fig. 7. Consequently when the plate 52 is pressed downwardly by reason of the free end of a lever 51 being lifted by one of the teeth of a wheel 37, as indicated by the dotted lines in Fig. 5, the end of the lever 26 is thrown into engagement with the ratchet-wheel 25, fast on the type-wheelshaft, and the operation already described occurs. The spring 28 applied to the lever 26 serves to return it and the plate 52 and lever 51 to their normalpositions. The relative positions of the teeth or projections upon the circumference of the driver and the characters in either series upon the circumference of the type-wheel are :such that when a given lever 51 is operated by its wheel in response to the depression of the corresponding finger-key, the corresponding character upon the type-wheel will for an instant remain at the printing-point. I prefer that the cams or projections on the driver shall not be so related to the spaces into which the face of the type-wheel is divided as that the projection that causes the arrest at the printing-point of a given space on the type-wheel shall be next on the driver to that which causes the arrest of an adjaany other suitable number.

cent space on the type-wheel, but that they be separated by intervals of four or five or Normally the characters in the upper series of characters on the type-wheel are thus brought to and maintained at the printing position. The wheel may be raised on its shaft to bring the lower series into the printing-plane in a variety of ways. I have shown a shifting-key marked Gaps in the drawings. It is connected by a link56 with one end of a lever v57, pivoted on the frame, whose free end lies under and in contact with a short arm 58, having one end pivoted in the frame and carrying at its free end a roller 59, running on the under side of a flange on the sleeve of the type-wheel, Figs. 3 and 7. When the cap-lever is depressed the type-wheel is raised, its upward motion being limited by the roller-stop 221. Any of the characterkeysmay now be depressed while the cap or shifting key is held down and the operations already described will occur. When the cap or shifting key-is released, a spring 50, Fig. 2, connected to the type-wheel sleeve and rachet-wheel 25, returns the parts to the normal position.

Any suitable hammer mechanism may be employed. In the drawings I have shown upon the shaft 22, Figs. 1 and 8, a radial arm 61, to which is pivoted a latch 62, engaging a lug or projection on a short horizontal arm 63, pivoted to the frame. A spring 64 presses the latch toward the projection on this arm and the outer end of the arm is connected by a rod 65 with one end of a lever 66, pivoted at the opposite end of the machine and extending rearwardly, its rear end being connected by a rod 67 with the hammer 68 adjacent' to its pivot. Normally a spring 69 holds the hammer retracted and draws the arm 63 against a stop 70, Fig. 1. When a keyis depressed and the operations described occur to maintain the desired characterupon the type-wheel for a moment at the printingpoint, the initial rocking of the shaft 22 draws the latch 62 toward the left, as viewed in Fig. 1, and through the connections described the hammer is thrown forward to take an impression from the'type-wheel. This occurs during the early part of the movement or swing of the plates 14 16, and the feed of the carriage, as hereinafter described, may be and in the organization shown is effected during the latter part of said movement. Some means is required for disconnecting the hammer from the swinging arm 61 after it has been thrown a suflicient distance to take a proper impression from the type-wheel. This may be effected in the following manner: On the latch 62 is an inclined or cam projection 71, which works against a surface 72 on the frame, and when the latch has operated the pivoted arm 63 through a suflicient distance to impart a proper impulse to the hammer the cam projection 71 will have moved the latch down to such extent as to disengage it the recoil of the hammer and under the stress of its spring 69 the rod 67, lever 66, rod 65 push the lever 63 back into its normal position to be again engaged by the latch when the toothed wheel'25 has been released and the parts 14 16, in returning to their normal position under the stress of certain springs, referred to later, rock the shaft 22 and the hammer-actuating arm 61 back into their normal position. The hammer is mounted upon an arm 73, secured to the frame at one sideor end and extending along the rear of the frame and over the carriage toward the other end of the machine, a space for the traverse of the paper being left between the arm and frame.

At the printing point and between the hammer and the type-wheel is a shield 74, consisting merely of a plate with an opening of proper area into which the hammer strikes in taking an impression. this shield is to prevent the paper receiving any impression except from the'character against which it is directly forced by the hammer. In the series of characters on the type-wheel there is a blank space, which is held at the printing-point when the spacekey is depressed and causes the actuation of the mechanism, as already described. Consequently when the hammer is thrown forward upon the operation of the space-key of the ham mer by which its movement toward the type-Wheel is limited.

An inking-roll 76 has its bearings in bifurcations of an arm or bracket 77, Fig. 1, hinged in a recess in the frame; The butt of the bracket'is squared (like that of a knifeblade) and a plate-spring 78 bears against it. The spring holds the bracket in normal position, and yet it may be swung out and so held by the spring, as shown by dotted lines.

A thumb-screw 79 affords a suitable means of adjusting the inking-roll with reference to the face of the type-wheel.

The carriage 80 travels in suitable guides or ways of ordinary construction at the rear of the machine and has a standard 81 at each end in which the large paper-feed roll 82 has its bearings. A smaller feed-roll 83, cooperating with the larger one, is mounted in front of it and also has its hearings in the end pieces 81 of the carriage. The bearings of the latter roll may, as is common to paperfeed devices of this character, be mounted in bearing-blocks'held in position by springs and capable of yielding. A curved guide plate or table 84 directs the paper to the bite of the rolls 82 and 83, whence it passes upwardly' between the face of the type-wheel and the shield 74 and when it rises it will The purpose of To preveht the blow of thefall backwardly and lie upon the inclined table 85, which affords a convenient support in making erasures and corrections. The forward step-by-step movement ofthe carriage will first be described and then the operation of the line-spacing mechanism.

When the shaft 22, Figs. 7 and 8, is rocked by the swinging of the plates 14 16 in which the type-wheel shaft is mounted, an arm 86 thereon moves a lever 87 against the tension of its spring 88, seated in asocket in the frame and compressed by a plunger on the lever.

The opposite end of the ieverprojects toward the machine. The rack 91, carried by the carriage 80, is in rear of the arm 89. Afeed-pawl 92, pivoted on the arm 89, is normally urged upwardly by its spring 93 and has a lateral rearwardly-projecting tooth 94, adapted to engage the teeth of the rack. It also has on its upper edge (shown in dotted lines, Fig. 2) a projection 95, the upper edge of which inclines downwardly toward the pivot of the latch and normally bears against a pin 96, projecting from the rear frame-plate 97, thereby holding v wheel 25 on the type-wheel shaft is engaged by the end of the lever 26, causing the plates in which the type-wheel shaft is mounted to swing upon their pivots, and thus maintain the required character for a moment at the printing-point, the first portionor period of movement of the plates 14 16 and the shaft 22 results in thus holding thecharacter at the printing'point and in the actuation of the hammer to take an impression therefrom. During this period of the movement while the hammer is operated and released as described the pin 96 rides down the incline of the projection 95 on the pawl 92 and allows it to rise and its tooth 94 to enter a notch in the rack. The final movement of the parts referred to causes the end of the lever 87 to continue its movement, and thereby cause the advancement of the carriage onestep after the hammer hasdropped back. Afterward all'the parts are returned to their normal positions by the reaction of the spring 90 applied to the arm 89 and spring .88 applied to lever 87.

IIO

The detent-pawl 98 is pivoted upon a post i 99, projecting'laterally from the rear'vertical frame-plate'97, and a spring 100, coiled around its'bearing,normally throws upwardly one end ofthe pawl and-causes a lateral tooth 101 thereon to normally engage the rack. The

opposite end of the pawl has on its lower edge "a projection 102, the inner edge of which is pawl 98 into the path of a pin 105, projecting l from one of the parallel Webs 106 on the bottom of the carriage. The lever 104 is a bell-crank lever, and its horizontal arm 107 is connected byalink 108 with an arm 109, Fig. 5, connected with a rock-shaft 110, from which extend radial arms 111, carrying a locking-bar 112, adapted to be thrown forward over the ends of the key-levers 29 to lock them. A spring 113, applied beneath the arm 109, tends normally to urge it upward, and consequently to throw the locking-plate over the ends of the key-levers and to raise the horizontal arm 107 of the lever 104. The parts are, however, normally held in the position shown in Figs. 2 and 5 by a three-armed latch 114, having a spring coiled around its bearing and tending to throw its hooked arm 115 upwardly to engage the projection 103 on the lever 104. The second arm 116 of this three-armed latch extends upwardly between the parallel ribs 106 on the bottom of the carriage in a position to be struck by a pin 118, carried by one of these ribs. The third arm 117 of this latch normally lies against the upper end of a vertical rod 119, the lower end of which bears upon a lever 120, pivoted at 121 and connected at its front end with a vertically-moving rod 122, having a finger-piece 123 upon its upper end located at the left inner corner of the keyboard, as seen at Fig. 7. The operation of these parts is as follows: As the carriage feeds from right to left in the ordinary way and the limit of its forward movement is approached, the pin 118 strikes the arm 116 of the threearmed latch and throws the arm 115 thereof outof engagement with the projection 103 on the lever 104. The spring 113, acting against the under side of the arm 109, projecting from the rock-shaft 110, Fig. 5, now urges upward the horizontal arm 107 of the lever 104 and throws the other end of the lever to the right, as viewed in Fig. 2. The projection 103 on the lever 104'rides against the projection 102 on the detent-pawl and throws its tooth 101 out of engagement with the rack. The actuating or feeding pawl 92 being normally out of engagement with the rack the effect of the movement of the parts just described is to cause the retreat or return movement of the carriage under the stress of the cord 124 of the spring-drum 125. The carriage is thus returned to the initial position for the commencement of a new line of printing. As the carriage approaches this initial position the pin 105 thereon strikes the end of the lever 104 and causes the projection 103 thereon to ride over the catch or hook of the latch 115 and bring the parts to the normal position. (Indicated in Fig. 2.) Wheneverit is desired to return the carriage to the initial position before the pin 118 engages the arm 116 of the three-armed latch, as described, the operator may press upon the key 123, thus forcing the rod 119 against the arm 117 of the three-armed latch and throwing its arm 115 out of engagement with the projection on the lever 104. During the return movement of the carriage the locking-bar 112 lies above the ends of all the key-levers and prevents the depression of any character-key.

The line-spacing mechanism shown in the drawings, Figs. 9 to 12, is constructed and operated as follows: The larger paper-roll 82 maybe hollow,as shown,Fig. 9, or may merely be bored out axially for the reception of the shaft 126, which is loosely fitted therein, so that the roll and shaft may turn relatively to each other. The roll has trunnions 127 128, turning in bearingsin the vertical end plates or standards 81 of the carriage. At the lefthand end of the roll the trunnion 127 extends beyond its bearing and has attached to it a disk 129, preferably flanged for convenience in using it as a hand-wheel, and outside of the disk a star-toothed wheel 130. A radial arm 131, keyed to the end of the shaft, carries a pivoted latch 132, having a spring 133, working against a wedge-shaped projection on the hub of the latch and serving to hold it either in or out of engagement with the teeth of the wheel 130. The latch has a thumb-piece 134, by which it may conveniently be thrown into either position. At the opposite end of the roll the trunnion 128 beyond its bearing is provided with a coiled spring 135, one end of which is attached to the trunnion and the other engaged with a radial arm 136, keyed to the shaft 126 and carrying at its end a roller 137 so arranged and adapted as to strike against the inclined or curved cam edge 138 of a plate 139, lying parallel with the axis of the roll. This camplate is carried by a disk 140, having a hollow boss or hub 141, turning in a bearing in a part 142 of the frame. The disk has three apertures 143 therein, adapted to be entered by a spring locking-pin 144, and may therefore be set in either of three positions at will. The end of the shaft 126 preferably extends beyond the radial arm 136, and its end is chamfered, so that it will readily enter the bore of the hub 141, through which it extends when the carriage is in the normal or initial position, as shown in Fig. 9. When the carriage after having completed its forward excursion is returned to its initial position by the strain of the spring drum-cord 124, the roller 137 strikes and rides along the inclined face of the cam 138 and produces a partial revolution of the shaft, contracting the coiled spring 135 and through it and the latch 132 turning the feed-roll 82 through the required distance to give the desired line-space on the paper, which is determined by the position of the cam 138. As the carriage is now fed forward step by step in the printing of a new line the roll 137 slowly runs down the cam edge 138, gradually relaxing the spring 135 without causing any movement of the roll 82, and comes against a stop 145, Figs. 1, 2, and 10. The latch 132 may be thrown out of en- IIO keyway in its socket.

gagement with the star-toothedwheel and be' so held by its spring and the roll 82 turned by hand.

The bearing of the lower plate 16, in which the type-wheel shaft is moun ted, is constructed as follows: A plate 146, having an annular track containingantifriction-balls, is seated in theframe and has a central aperture or bearing, whichalso extends through the frame, in which is seated the hearing or journal 17 of the plate, which rests upon the bearing-balls. A washer 147' may be applied to the endof' the journal'and held in place by a screw. The bearing of the upper plate 14 is constructed as follows: A flanged bushing 148 is fitted to move vertically in a correspondingly-shaped open socket in the frame. Its vertical movement is limited by its flange, and it is held against rotation by a key 149, working in a The bushing is bored throughout its length, and the upper part of the bore is of larger diameter than the lower part, thus forminga shoulder 150. Its under face is provided with an annular channel concentric to the bore of the bushing, in which are antifriction-balls. The journal 15 of the plate 14 is inserted from below. The plate bears against the antifriction-balls and is held in the bushing by a washer 151, bearing against the shoulder 150 and secured on the end of the journalby a screw. A screw-bolt 152 works in the upper part of the enlarged bore of the bushing and is formed with an enlarged head having an annular groove 153 therein, in which lie the two horns or bifurcations 154 of the top plate 155, which is secured in position by screws, as seen-in Fig. 1. The screw-bolt 152 may therefore be rotated to raise or lower the bushing, which is held against turning by the key 149, and adjust the bearing of the type-wheel shaft.
