SPECIFICATION forming part of Letters Patent No. 570,433, dated October 27, 1896.

Application filed July 9,1895. Renewed October 5,1896. Serial No. 607,967. (No model.)

To all whom it may concern.-

Be it known that I, BERNARD GRANVILLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-\Vriters, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention herein set forth is an improvement upon the machine shown. in Letters Patent of the United States patented to me on the 25th day of April, 1893, and num- The general principle of operation of said patented machine is retained in the machine herein described, and my present invention consisting of details of construction and of parts added or changed in form.

The objects sought in this invention are in part the improved operation of the machine and in part cheapness of construction. and durability.

My said invention is illustrated in the accompanying drawings, in which the complete machine is shown, as well as the details and features which constitute my invention.

Figs. 19 and 20 show in plan and elevation a key-lever, while Fig. 21 is a detail of the end of the key-lever before it is bent to form the finger-piece. Fig. 22 is a detail view of the pressure-roll and its bearings. Fig. 23 is a detail perspective view of the paper-clip. Fi 24 is a detail perspective view of the eseapement-pawls and their opcrating-wiper.

The frame which supports, directly or indirectly, the working parts is so formed that it may be made of cast metal. It is shown in plan in Fig. 1 and in side elevation in Fig. 2. It has two side bars A, two pairs of posts marked 13 and C, respectively, and two crossbars connecting the side bars directly, marked, respectively, D and D. Between the rear posts 0 is a connecting-bar E. Between the front and rear bar is a reinforcing rib l).

The key-levers 1 are composed of horizontally-arranged plain bars set on edge and turned up at the forward ends, as shown at 2, to support the finger-pieces 3. These levers are notched at the rear ends on the upper edges and fulcrum upon the lower edge of the cross-bar E. A comb 4. is pinned to the front face 'of the bar E, and in its slits the rear ends of the key-levers are held. Springs 5 have upturned flanges (3 on their free ends, which embrace and bear upon the lower edges of the key-levers and tend to hold the front ends raised in normal position. The fixed ends of the springs are clamped to the rear crossbar D, as shown at 7.. The plungers or type-bars a are reciprocated in.

direct lines, as in my aforesaid patent, in a rocking frame, in which these bars converge to a common printing-point. The front ends of these bars are connected to the longer arms of bell-crank levers 8 and 9, which are in turn pivoted to

posts

10 and 11, and are connected by

links

12 and 13 to the key-levers. The

lower ends of these posts are notched. These lower ends are fixed in the front cross-barl5 of the cradle-frame by setting them in' the mold and casting the metal around them-- this to avoid the expense of drilling and rivposts on each side eiing. The links are shown more clearly dotached, as in Fig. 16. They are struck out of sheet metal with slots at the ends made to fit over the levers, which they connect. The lower ends of these links are held in place upon the key-levers by special construction. (Illustrated more clearly in Figs. 19 and 20.) \Vhen these levers are struck out, spring; tongues I) are also struck out free at one end and left integral with. the metal at the other end. These are reversed to each other, the free ends being directed toward each other, with a space between to receive the link, which is slipped on over the tongue into the space in which it is held. This accurately locates and holds the link, and depression of the lever pulls down the short arm of the bell-crank lever and projects forward the type-bar.

The front ends of the type-bars are connected to the bell-crank levers by a special form of links 10. These are struck out of sheet metal in the form shown in Fig. 14:. These blanks are bent on the line m 0?, equally dividing the intermediate part 17', and when thus bent the sides and projecting ends are separated by a space sufficient to admit the edge of the type-bar. The end of the lever-arm is provided with a pin 18 fixed therein and projecting on each side, and a similar pin is in the forward end of the typebar at 1!). The holes 19 in the link are fitted to these pins, and connection is made by spreading the ends of the link and allowing them to spring back over the pins. The bent part 17 rests on the upper edge of the typebar when the parts are in normal position, and the forward end of the link rises when the key-lever is operated to impel the bars. The parts are returned to normal position by the spring 5.

The backward movement of the bell-crank levers is limited by a stop 20, composed of a rod held upon arms and incased preferably in rubber tubing. A similar stop 21 lies across the upper surface of the key-levers and limits their return movement. This stop lies just in rear of the upturned ends of the key-levers.

In order to form inexpensively the fingerpieces on the ends ofthese levers, these ends are made in. the stamping of the lever, as shown in Figs. 19 and 21. The end is cut approximately in the form of a circle, leaving a nearly complete disk 22, with slits 23, which partially sever the disk from the end of the bar, leaving a narrow neck 24, which, when the disk is turned up at right angles to the neck, as shown in Fig. 17, leaves the neck connected with the center of the disk, which forms the base of the cap. Thecap is completed, as shown in section in Fig. 20, by placing on the disk another disk 25, which is held in place by a thimble 26, forced down over the edge of the disk 22.

The general principles of construction and operation of the cradle which carries the typebars is the same as in my aforesaid patent of 1893. It differs, however, in details. The base of the frame is the transverse bar 15, in which the

posts

10 and 11 are embedded. The arms 28 are cast in one piece with the standard 28 and the base-bar 15. Across the rear ends of the arms 28 is fixed another casting consisting of two

curved bars

29 and 30, on the ends of which are posts 31 and This casting is held upon the arms 28 by a screw at each end, and upon it are fixed guide-plates and 34. These plates are pierced for the passage of the type-bars, the holes in the plates forming guides for the bars. These plates may be made of hardened steel, so as to resist the wear. The main frame of the cradle is formed with two arms 35 extending from the end of bar 15 forward on each side of the bank of keys, and on their forward ends they have finger-pieces 36, by

.means of which the cradle may be tilted to bring the caps into alinement. The rear end of the cradle is down normally, so that the upper row of characters is normally in alinement with the printing-point. hen the lower rows are to be brought into alinement, the cradle is tilted by pressure upon the finger-piece 36 on either side of the bank of keys. 0n the left side I have provided a locking device consisting of a pivoted arm 38, which has a stud 39 and is held by a spring 40. The arm is so arranged that when it is tipped forward it is out of connection. \Vhen it is tipped back, the stud 39 strikes a stud 4:4; 011 the arm '35 on the left side, and thereby throws down the arm 35 and locks the cradle with the lower row of type (usually capitals and character less used) in range with the printin g-point. The connection with the spring shown in Fig. 2 holds the arm 38 in both positions.

The cradle is pivoted at 5, and requires but slight movement. The pivot being near the front end of the cradle, its rear end drops by gravity, which I have found to be the best mode of returning it, as I thereby avoid the rebound of a spring.

The movement of the cradle is limited by stops 4.6 and 47. The stop 48 consists of the upturned rear edge of the plate 48. On an arm extending downward in rear of the stop 48 is a buffer 49, clamped under an eccentric disk 50, held by a screw 51, which presses the disk into the leather. The amount of motion permitted the cradle may be regulated by loosening the screw and turning the disk thereon. The stop 47 is a projection on the cradle-frame, with projection and buffer 52, which is constructed and held adjustably the same as the buffer 49.

In rear of the cradle, and between it and the printing-point on the type-cylind er K, are guide-plates 53. These are supported upon a stud 54 on the main frame. The plates conthe heads of the type-bars.

IIO

of the plates is shown more clearly in Figs. 2 and 10. The ends of these plates are close to the face of the cylinder which carries the paper and serves as a platen. It will be observed that the type bars converge, but carry the heads on which the type are set arranged squarely to the platen, so that the type may be impressed in lines at right angles to the surface of the paper. In order that the blow may be delivered in the same direction, I have provided a central guide consisting of the plate 55. This plate is hung so as to swingfreely within the narrow limits permitted by the guide-plates 53, between the forward ends of which the central guide proj ects. The central guide may be thrown from side to side, according as the right or left hand type-bars are brought into action. The central guide-plate is loosely connected on the central vertical line with the plate 33, and whether the right-hand type-bars or the lefthand are in action the central plate forms the auxiliary guide on one side and one of the fixed guides 53 serves as the guide on the other side. These guides being properly adapted to the heads on the type-bars, they accnrately direct the type to the printing-point This guide is lateral, but as the bearings in the curved plates are widely separated, the type have accurate lineal alinement from those bearings. On whichever side the typebars are acting, the guides cause the type in its final movement to strike squarely against the paper.

I have changed the construction of the frame which supports the connecting ribbon on both sides of the printing-point and raises and lowers it so as to interpose the ribbon when the impression is made, and to lower the ribbon when the type-bar is withdrawn. This frame I have shown as struck up out of thin sheet metal. It is shown at O in Figs. 1 and 10. Part consists of two long arms 60, having bearings 61 in standards 61, 011 which they move. These arms converge to the front ends of the guide-plates 53. At this point they are formed on one side with a wing62, which, when the frame is down, rests on the top of the guide-plates, and in this position the ribbon is below the line of print. The arms extend backward to the points 63, from which points it forms a how 64, with arms 65, which are turned up to make a loop for holding the ribbon. There is a similar loop on each of the arms, at (36, and the ribbon is led from the spools through the loops 66 and G5 and across the loop on the other side, and so back to the other spool.

On each end of the frame 0 is rearwardlyextending arm 67, made preferably of steel wire, which extends to the rear of the pivot and forms the lever-arm by means of which the frame is raised to bring the ribbon over the printing-point. These arms are connected by rods 68 with a transverse bar 69, which lies under and across the key-levers, so that on every depression of the key-levers made removable easily.

the ribbon is raised and the parts are so adjusted that the ribbon rises into place before the type'bar has delivered its blow. A light spring '70 returns the frame and ribbon to their low position, thus disclosing the character which has been printed. The shafts 71, which carry the spindles for the spools, are mounted in vertical bearings in the main frame and have beveled gears 72 in mesh with other beveled gears 73 on the horizontal shaft 7 4, also mounted in bearings in the main frame. The shaft is longitudinally adjustable and the gears 73 are separated, so that upon shifting of the shaft 7 4: eitherone or the other may be thrown into mesh, so that the ribbon may be fed in either direction by simply pushing the shaft. The shaft 74 is turned by means of a bevel-gear 75 meshing with another bevel-gear 76 on a shaft prolonged from the axis of the escapement-wheel, which permits the carriage to move to the left in printing the line.

The spools are made of disks 77, struck up out of thin sheet metal and connected by sleeves fitted to admit a spindle. For convenience and economy I make the spindle 7 8 of the same diameter as the shaft which carries the beveled gear '72, and I support this shaftin its bearings by a small collar 7 9, which is forced down over the spindle. The spool is held by the frictional contact of a spring 80, which is made in the form of a bow and set in a slot milled longitudinally .in the spindle, the spring being held by pinching the walls of the slot against the spring.

The carriage-bed is formed of a separate casting consisting of a frame formed of side bars 81 and 82, connected by cross-bars at the end, the side bars being planed out to form guideways for the trucks on which the carriage moves. The front bar of this bed is made higher and upon it are formed the arms which carry the bearings of the spool-shafts, and also the arms which support the drivingshaft for the spool. The carriage-frame has end pieces formed of castings, as shown in Figs. 2 and 6. The main connections between these end frames consist of the rack-bar S4, fixed to the rear leg 85, and a rod 86, fixed to the front leg 87. The right-hand bearing for the paper-roll K is at the point 89, being a simple hole opening inwardly. The left-hand bearing 90 is an open slot, in which the shaft is held by one of the springs 91, it being thus The pressure-roll 92 is set in hearings in spring-arms 93, pivoted 011 the inner faces of the end frames. The springs 93 of these arms are controlled by set-screws 95. In front of this roller, on the same arms, is fixed a thin bar 94, beveled to fit the contour of the paper-roll.

In rear of the pressure-roller is a curved plate or paper-shelf 96, the ends of which are supported by bearing against the ribs on the end frames, being held in place by the clips 97 98, which are bent to bear on the lower.

side of the shelf at X, and have forward extensions engaging the shelf. For convenience of construction the clips 08 are turned over the bar, and so held thereon, and, extending underneath, are turned up to form the front springs, which guide the paper in front of and over the roller. On the right-hand clip 08 is pivoted the dog 00, which trips the bellhammer.

The ratchet-wheel, by means of which the paper-roll is turned for line-spacing, is on the right-hand end of the roller. It is operated by a pawl 100, which has a tooth 1.01 arranged to engage with the ratchet-wheel. The pawl extends up between stop-arms 102, east upon an arm 105 on the right-hand end frame. The pawl is pivoted upon the end of the frame 105, the arms of which are pivoted at 106 011 the innerface of the end frames. The pawl is held in engagement and at the same time pulled back after action by means of diagonally-arranged spring 107. The arm of the frame 105, on the left hand, extends to the rear, as shown at 108, and engages with a bell-crank lever 10.9,pivoted on the end frame. Against the lower arm of this bellcrank lever bears the end of a freely sliding rod 110, the right-hand end of which is arranged to strike upon an adjustable stop 111, set on a rack-bar 112, fixed to the rear of the main frame of the machine. The sliding rod is held in guides 113 114, the latter being in the end of the arm 115, through which the carriage is moved. \Vhen the rod strikes the stop,it operates the frame through the bell-crank lever, causing the pawl to rise and move the paper-roller one notch, so that this movement is caused by the return movement of the carriage, and the shock of the stop is taken up in the work done by the pawl and the tension of the pawl-spring. To vary the space, I have provided a line-space regulator, and for economy of construction this is made of special shape. It consists of a piece of sheet metal cut out in the shape shown in Figs. 6, '7, and 8. It has a pivot-hole 116, and in the same plane with the part having this pivot-hole an arm. turned up to form a guide for the tooth of the pawl. Another arm 117 is bent over the arm 10% of the end frame, and on the end of this bent arm 117 are two stops 117 which limit the upward and downward movement of the arm 117. A pin 11S engages with the arm 117, which springs over the pin and holds it in raised position. The pin projects from the arm 104:, and the arm 117 has an opening, Fig. 8, to engage the pin. This piece is pivoted upon a shoulder in the frame around the bearing of the paper-roll.

The line-space regulator has a curved edge 117 concentric with the teeth of the ratchet and projecting sufficiently to form a rest for the pawl-tooth 101 to rest against, and thus be held out of engagement with the ratchet, and by adjusting this line-space regulator to its extreme position more or less of the ratchet-teeth will be exposed to be engaged by the pawl, the edge acting as a shield during part of the movement of the pawl.

The arm and lever for moving the carriage are substantially like those in my aforesaid patent. The part directly underneath is in the form of a bell-crank lever, marked 110. It is pivoted near the front of the machine at the angle, and the shorter arm extends across the machine and is connected to an arm 120 on the shaft 121 in the forward posts 13. This shaft has arms 121 with finger-pieces upon the ends extending to the side of the keyboard, so as to be within reach of the operator without removing his hands from the keyboard. There is one arm at each end of the shaft, so that the carriage may be moved by either hand. The long arm of the bel crank lever extends to the rear and is connected by a link 122 to the arm 115, the upper end of which is struck up in form of a box, in the sides of which are the bearings of the stop-rod. The sides of the box are extended and turned out, as at 123, the turnedout ends being screwed to the rack-bar of the carriage. lVhen the carriage is free, therefore, it may be moved in either direction by manipulation of the arms extending to the front by the side of the keyboard. The arm 115 has an offset 115 fitting over the shaft of the spring-tightening device, on which is the knob 124:. The shaft of this knob carries a ratchet-wheel 125 outside of the plate 126, which covers the rear of the machine, and this ratchet-wheel has an esca'pement-lever 127, provided with a finger-piece. The shaft passes through the back bar of the carriageframe, and upon it near the forward end is the pulley 128 loose on the shaft, but held by means of a collar 129 against endwise move ment. The pulley is provided with a case 130, in which is a coiled spring, one end of which is secured to the case and the other to the shaft.

The tension of the spring may be increased by turning the knob to the right, or may be diminished by manipulating the escapementlever.

The shaft abuts end to end against the shaft 7 6*, which carries the pinion 76, hereto, fore described,which drives the ribbon-spoolsand the shell 130 is connected to the ribbonshaft by a pawl-and-ratchet connection, the pawl being carried by the shell 130 and the ratchet by the shaft 7 6*, so that the movement of the carriage to the left is accompanied by a movement of the ribbonshaft, which remains stationary when the carriage moves to the right.

The escapement-pawls 131 132 are mounted upon an eccentric-screw set in the standard 131 on the carriage-bcd. They are provided with springs and pins 13-1, which extend over a wiper or cam plate 135. This has one high part for one pin and another for another, marked,respectively,136 137, so arranged that one pawl is always held out of engagement with the rack-bar. The high parts, however,

are so arranged and shaped, as shown in Fig. 4, that by certain lesser amount of movement of the cam-plate the alternate escapement motion of the two pawls is secured, but by a greater movement to the left of the camplate both pawls are released and the carriage is set free. The cam-plate, which is in the form of a broad blade, is carried upon an upright arm on a bell-crank lever 138. Another arm 139 of this lever is connected to the retracting-spring, which causes thecamplate to retreat to the right. i

The horizontal arm of the bell-crank lever 138 extends over an arm 1&1 on a rock-shaft 142. This rock-shaft has arms hi2 projecting forward connected to the bar 142, which extends under the key-levers. Thekey-levers appropriate to the printin g-characters depress this bar only enough to operate the escapement, but there is a key-lever on the right of the machine, 143, which has a-greater range and will depress the bar far enough to fully release the pawls, as before explained. 0n the left of the keyboard is the finger-piece of a key-lever 144, which is connected by a link Mi to an arm 145 on a sleeve which carries an arm 146, the sleeve being supported upon a stud on the carriage-bed. The arm 146 eX tends under the frame 105, which carries the pawl operating the line-feed, and by the manipulation of this key-lever the paper-roll may be operated at will and independently of the automatic mechanism above described.

I have provided means for adjusting the spring 135 which returns the cam-plate operating the escapement-pawls of the carriage, and thus for varying the amount of pressure required to operate the keys of the type-levers.

zontal flanges on the lower edge.

This consists of a screw connection and thumbpiece 147 on the left-hand side of the machine; by means of this the tension of the spring upon the bell-crank lever which carries the cam-plate may be varied.

I have in front of the bank of keys an ordinary spacing-bar which operates the escapement in the ordinary way.

It will be observed that the type-bars are formed with. thicker rear ends and thinner at the forward ends and are provided with hori- These horizontal flanges form a broader bearing and also fit into lateral notches in the guide-plates, so that they are held securely against displacement. I have provided a special construction for the pins which are set in the type-bars and in the bell-crank levers for the removable link which connects these parts. The pin is shown enlarged in Fig. 18. It has a peripheral groove 150 a little aside of the center, and when this pin is inserted in the lever or bar the metal is struck up into the groove, as shown in the figure, so that the pin is held therein with very little trouble and expense.

It will be seen from Fig. 2 that the

links

12 and 13, which operate the type-bar levers, are arranged radially in relation to the pivot 45 of the type-bar frame, and when the frame is tilted on the pivot 15 to change from upper to lower case there will be no tendency for the operating conneetions'zi. a, the links and the type-bar levers-to be changed in relation to each other nor no straining or tension will be placed on the parts. The nose of the bellcrank lever is also so arranged and constructed that it willbe impossible for the link to become detached therefrom, and in linking or unlinking the machine it is necessary that the type bars and levers be at their extreme limit rearward before the links can be attached or detached, the said links merely resting in the hook of the nose and having no pivot-pin con nection therewith.

The roller-frame 151.,upon which the papercarriage works, I have found must be of special construction to avoid binding of the same on the stationary ways 81 82. This rollerframe is shown in Figs. 2 and 12, and consists of two side bars 152, a connecting-bar 153 at one end, and the rollers 154. I have found that it is necessary that one of the side bars must be rigidly fixed to the cross-bar, and in the drawings I have shown the rigid connection as effected with solder at 3 though I do not limit myself in this respect, as the rigid connection may be made in some other way. This form of frame keeps the rollers in line and prevents creeping of one roller in advance of the other, which would result in binding of the roller-frame and carriage. The rollerframe has two spurs 155 struck from one of the side bars, and these are in line with a pin 156, shown in dotted lines in Fig. 2 as depending from the front bar of the carriageframe, so that should the roller-frame get out of its proper position relative to the carriageframe, the pin on the carriage will move the frame into proper relative position.

The stop-bars 20 and 21 for the type-bar levers are held to the machine by spring-arms 20 21, which are attached to the stop-bars by the ends of the bars which project beyond the rubber tubing entering openings in the spring arms or clips, so that it is only necessary in order to remove the stops to press back the spring-arm at either end of the bar and remove the same. The projecting ends are squared oif on one side at 20 21" to fit the holes in the clips.

The rear one of the type-bar guide-plates 34 has notches 34 in its edges for the typebars of the upper and lower case, as before stated, and these notches are of the peculiar form represented in Fig. 9that is, the vertical portion of the notch 34 is enlarged laterally at 3t and the type-bars have lateral ribs 345 corresponding thereto. The notch and type-bar are relatively proportioned so that the type-bar may have lateral play, but the ribs fitting in the lateral enlargements of the notches will be guided accurately against vertical displacement. The openings in the guide-plate 33 are merely plain slots and do not have any effect to hold the type-bars against free lateral play, excepting by their end walls, which confine the outer type-bars of the set and those in turn confine the next inner type-bars, and so on throughout the set, it being understood that the type-bars are so fitted to the slots as to permit lateral play of the said bars to prevent sticking, and these guide-plates are notdepended on to guide the type-bars laterally, but for this purpose the converging guide-plates 53 and the shifting guide-tongue 55 are used. The said tongue .is held pivotally in place by merely notching its upper and lower arms and fitting them to the edges of the slot in the plate 33.

The pawls 131 132 of the escapement are, as before stated, carried by the standard 131 and this is pivoted at 131 to the machineframe, and is under tension of a sprin 131", connected thereto and to the cross-bar 131,extending between the ways 81 82. This spring tends constantly to force the standard and hold it against a stop 160. The purpose of this arrangement is to provide a support for the pawls which will be perfectly rigid while the step-by-step movement of the carriage from right to left is taking place, and which will yield and allow the pawls to yield when they are returned into engagement with the carriage after the carriage has been released and has acquired considerable force and mo mentum in its free passage from right to left. The standard 131 is also held rigidly against the stop 160 by the spring when the carriage is thrown to the right for beginning a new line, as the strain or shock on the pawls at this time is no more than that resulting from the ordinary step-by-step movement.

I have provided an arm 161, Fig. 2, connected with the shaft 142 and extending up in the range of the paper-clip, so that when the paper-cli p comes opposite this arm the arm will strike the clip and act as a lock to the depression of any key and to prevent the release of the escapemcnt- As the shaft 14:2 is moved bythe universal space-bar 142" at each key action, it follows that the arm 161 is also moved, and as the shaft 142, with its arm 141, controls the escapement, the striking of the arm 161 against the paper-clip when the latter comes before it will prevent the escapement from working, and also prevent the depression of the keys. In order to prevent the movement of the clips past the printing-point, an arm 162 projects inwardly from the frame, and in the same vertical plane as the prii'iting-point, and in line with the paper-clip to strike the same and prevent them from extending over the printing-point. The carriage is operated from the pulley 128 by the cord 128.

The adjustable stop 111 is made from a single blank, (shown adjacent to Fig. 4,) said blank having the body portion and the tongue 111*. The blank is struck up on the dotted lines, shown so as to make the body portion of channel or U shape in cross-section, the tongue or spur 111 being struck up at the same time. This provides a cheap and efficient form of stop. This stop-piece has the rear end of its upper flange bent down to form the pa wl-tootl l for engaging the rack, and a leaf-spring (indicated in Fig. 4) between the lower flange and the lower edge of the rack holds the stop-piece against movement longitudinally of the rack. The said channel-stop is retained. in place be tween the rack and the rear side of the carriage by the rack-bar extending through its channeled face.

The pawls of the escapement, as shown in Fig. 3, are held by an eccentric screw 131", and by turning this screw the pawls may be adjusted in relation to each other.

The object of this adjustment is to get the spaces between the letters of the proper size to suit the type.
