Application filed March 27, 1897. Serial No. 6291606. (No model.) i

To all whom it may concern:

Be it known that I, FERDINAND G. STALL MAN, a citizen of the United States of America, residing at Philadelphia, in the count-y'of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Type-Writing Machines; and I do hereby declare the following to be a full, clear,

, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make and use the same, reference being had to the accompanying drawa into position with respect to the key actuated for printing and to effect an impression therefrom; and in such connection the invention relates particularly to the general construction and arrangement of the parts of such a machine.

The principal objects of my invention are, first, to provide an efficient, reliable, and comparatively inexpensive type-writing machine adapted to meet the requirements and perform the functions of a first-class type-writer; second, to provide a keyboard-lever with a series of keys closely arranged in rows throughout the breadth of the keyboard, so that the pressure in writing will be applied within a small space to maintain a simple and equal leverage, thereby permitting of an equal movement throughout the breadth of the keyboard-lever, the said lever being adapted to be guided to permit of equal movement throughout the length thereof; third, to provide a keyboard-lever and type-segment with a resisting force and in imparting certain movements to the type-segment with means controlled through the keyboard and certain levers for regulating the said movements and resisting force, so as to maintain an equal tension for each stroke and of any with its mechanism so arranged and conchanged in order to accurately adjust the throughout its entire depression; fourth, to

provide a keyboard-lever and type-segment S5 structed of light material, the type-segment having the characters most in use so grouped and arranged as to permit of easy movement of the said keyboard-lever still maintaining simple movements of the said segment; fifth, to simplify the construction of such a machine, including the keyboard, and to arrange the stops or keys so that the position of their lower extremities or depending stems may be type-segment to the end that the type may be brought into the exact position to effect a sharp and distinct impression therefrom upon the paper; sixth, to provide means for printing and spacing a letter or character laterally and in alinement at eachsingle successive stroke of the keyboard; seventh, to provide the upper surface of the keyboard with a lettered sheet, over which is secured atransparent covering to preserve cleanliness, both being perforated to fit over the keys; and eighth, to generally improve and simplify the construction, arrangement, and operation of a type-Writing machine.

It may be stated for the sake of convenience that the machine is divided into five classesviz., first, the keyboard-lever and its tension mechanism; second, the type-segment and its shafts; third, the reversing mechanism; fourth, the carriage-feed-gear mechan ism; fifth, the disk or checking-wheel and controlling mechanism.

My invention consists of a type-writin g ma chine provided with a keyboard-lever supporting a transverse shaft, said keyboard consisting of a casing with girders and carrying a series of adjustable keys, with depending stems supported in guides upon said girders and arranged closely in rows, and keys projecting through the slots at top and bottom, the said shaft having a changeable quadrant-f lever provided with a spring acting upon its front or tooth end through a cam pinion wheelf cord, and ratchet grooved disk. The said quadrant lever is connected by a pawl through a pinion upon the shaft to a stationary rack and is also connected by the same pawl through the pinion and shaft, its arms, and rods to a slanted-edge sliding plate in three sections beneath the said keyboard and said keyboard-lever connected to a guidinggear.

My invention further consists of a type-writing machine provided with a type-segment and its shafts, said segment mounted upon a frame and actuated by and connected to the keyboard-lever by slotted shafts and tooth members having an equalized lateral and rotary movement and a movement at right angles to said rotary movement (I prefer this to be known as the shift movement in the case) which is connected to and governed automatically by checking mechanism, and the face of said segment being curved and having characters fixed thereon, capitals on one side throughout the breadth, small letters, &c., on the other side throughout the breadth and arranged in a series of rows, an inner and two outer rows, respectively, and said characters deviating throughout the breadth of face, so that each outer character will follow an inner, one after the other, and the said rotary movement and shift movement are controlled through the keyboard and changeable swing and check levers, and the segment having a connection to independent helical springs for relieving the weight of same, so that arm will slide freely and return to normal position, one of the springs holding the segment against a fixed point on its shaft and traveling therewith.

My invention further consists of a typewriting machine provided with a reversing mechanism consisting of a pair of bevel-tooth members secured to the ends of a grooved sleeve adapted to be rotated by the keyboardlever and governed by and connected to an independent kcy-lcver on the side of the machine by means of a slotted shaft and a toggle mechanism so arranged as to shift the tooth members in either direction horizontally independent of that of the type-segment, thereby causing either member to be engaged to the typesegment pinion and locked in place, according as to whether a capital or small letter is to be printed, and the said mechanism adapted to move step by step with the type-segment across the machine.

My invention further consists of a typewritingmachine provided withra carriage-feedgear mechanism consisting of a laterallymovable frame supporting a type-segment and mounted by a roller on a shaft and actuated by the keyboard-lever, said carriage connected to transve se telescopic extensionshafts, one within the other, and forming a U-shape slide adapted to straddle the paper, said slide having a type-hammer guided by a transverse support or bar, said paper held in place by means of springs against suchasupport, and said slide having an extension arm and roller and supported upon a telescopic extension-tube adapted to be drawn out manually to fit within a socket.

My invent-ion further consists in providing a carriage with the means for moving it across the machine, consisting of a spring connection on one side of the machine from the frame of carriage by a cord through a pulley and cam sheave and ratchet grooved disk adapted to equalize the tension of the spring, and a rack-tooth connection on the other side from said frame, and the said teeth adapted to be acted upon by a keyboard-lever for moving the carriage step by step through the intervention of a double pawl-feed lever having a lug for each pawl for controlling the stepby-step movement and by a sliding bar and auxiliary pawl-lever and the handle or projection traveling with the rack-teeth adapted to control the release of the carriage, and thereby return it to its normal position.

My invention further consists of a typewriting machine provided with a checking or controlling mechanism consisting of a perforated disk mounted on a shaft and having holes or openings parallel to its axis all around the circumference and rotated by and connected to the keyboard-lever mechanism by means of a pawl and ratchet-wheel, and also connected to the type -segment and checked by its same means and at the same time, and havingrods, three in numberviz., upper, lower, and side rodssaid rods guided in supports and having springs to return them to their normal position, and said rods having a sliding movement adapted to be governed bysaid disk and to penetrate the same independent of one another in such a manner that when two are checked the other is brought into play. Said rods are connected on one side of the machine to the type-segment through a lever, bell-crank, rods, and a slotted shaft having a sliding extension-arm and connected on the other side of the machine to the keyboard-lever by changeable swing and check levers, bell-crank rod, and guiding gear-shaft having an arm, and the said connections adapted to shift and control the type-segment in a direction at right angles to the plane of its rotary movement, and the latter bell-cran k having an extensionarm and rod adapted to strike the hammer against the type through the intervention of a rectangular swinging frame or rock-shaft.

My invention further consists of a typewriting machine provided with ribbon-rolls suitably supported upon bed-plate and having an inking-ribbon adapted to be held by pins in way of the full length of a line of printing and adapted to be struck by the hammer to create an impression upon the paper, and said rolls may be actuated manually after a line of printing has been completed.

7 surface.

H H designate the side members of the main keyboard-levers, which are fulcrumed or pivoted to the upper part of the supports F at a point where the pitch-circle of pinion coincides with quadrant-lever, so as to allow the keyboard-lever to pursue its downward movement after the driving-pinion has been checked, making this intersection the swinging point or pivot of the quadrant-lever, as hereinafter described, said pivot-point being on a line with the main driving-shaft B, said members If being curved to pass beneath the main driving-shaft, as shown in Fig.2, and to the forward ends of these members or levers I-I issecured the keyboard I, consisting of two parts, the upper part being provided on its upper surface with a series of transverse slots or grooves 1 in which the fingerkeys I are located, said keys-being pivoted to short guide-pieces z", of hard rubber, which are let into shallow recesses 2' in the keyboard and rest upon rubber strips or bands 6 adapted to return the keys to their normal position after being depressed. The upper partof the finger-keys I are semicircular and extend partially through the slots I in the upper part of the keyboard, while their lower ends depend into recesses in the lower part ofthe keyboard, so that when a key is depressed it will extend below the keyboard and form a stop to arrest the sliding movement'of a plate hereinafter referred to. -By forming the up-.

per part of the finger-keys semicircular the position of the lower ends thereof can be changed without changing the contour of the upper end or presenting a different touch The keys are held to the rubber guide-pieces 2" by f rictionallcontact therewith, so that the position of the lower ends of said keys can be readily changed.

As the position of the lower extremitiesof gage the pinion H the keys are changed in relation to the slanted edge of a plate P it will eifect or adjust the extent of its movement in such a manner that when its position is changed to come opposite a lower or higher point of contact along the edge the extent of the movement of said plate will be greater or less accordingly, and therefore if the plate P is thus efiected and being properly connected to the type-segment it will regulate the printing position of the type.

eled to provide three inclined faces or edges 19, 19, and 10 as shown by dotted lines on Fig. 1, the inclinations being of the same angle, but deviating throughout the breadth of the plate to divide the keys of the keyboard in three sections, which correspond to the re .spective edges or faces which form the points of contact, or checking-points, of the plate P with the keys. Each outer point of contact will follow an inner point of contact of the same relation, oneafter the other, so that if a key of the inner section is depressed with the keyboard it engages the edge of the plate P, arrests the same and the checking-wheel 'or controlling mechanism, so that the sliderod 3, which will penetrate the checkingwheel, will effect the spring but not the typesegment. Should a key of theouter section to the left be operated, it will check or hold the checking-wheel in such a position as to allow The plate P, hereinbefore referred to, has a 'rear straight edge, and the front edge is bevthe upper rod 1 to penetrate it, and thereby shift the type-segment in one direction, and

the operation of any key of the outer section to the right will operate the lower rod 2 the same way. Therefore each edge of the plate has a rod to correspond. The pitch of the different points of contact or checking-points of the'plate and disk in the direction of their movement is in proportion or corresponds with the pitch of the characters on the type- 7 segment in the direction of its rotary move-- ment. 7 7

Upon the upper side of the keyboard is placed a sheet of paper or other material having printed thereon .the characters corresponding with the type-segment, and over .said sheet is placed a transparent sheet, as celluloid, to preserve cleanliness.

The rear ends of the side levers II of the plate A, and upon the shaft to one side of the pinion H is loosely mounted a quadrant-lever K, while upon the other side of said pinion the shaft-carries rigidly connected thereto a collar L, having a forwardly-projecting arm Z, to which is pivoted a pawl Z, adapted to en- ,with a projecting end, which is connected to the quadrant-lever, so that'when the quadrant is in engagement with the pinion and thepin- .ion is turned by the segment-rack the said.

. position.

quadran t-lever will be turned therewith. The front end of the quadrant-lever is provided with teeth which mesh with the pinion M, mounted upon a transverse driving-shaft having a pawl-arm, said pinion M being rigidly secured to a disk or wheel M, having an involute or cam M together forming a cam pinion-wheel, to which a cord or flexible connection m is attached, which extends to a grooved disk 921?, having a ratchet on one side and a spring m on the other side.

13y connecting the helical spring to the involute or cam a uniform tension upon the pinion M is maintained, and as said pinion is in mesh with the quadrant-lever K and the quadrant-lever is connected to the pinion on the shaft of the main keyboard-lever H by the pawl Z the tension of the spring will be conveyed by the said lever II and maintained until such connection is broken by the sliding plate P contacting with key of keyboardlever, after which a supplemental tension or equalizing device, hereinafter described, will come into play.

N designates a toothed sleeve, either one of the tOO'tllGLljllOllllJGlS a and n being adapted to be brought in mesh with apinion c, secured to the shaft C, which carries the type-segment C, and the toothed sleeve N is provided with a groove n for the reception of a bellcrank arm 0, acting as a guide, which is supported on a frame F, said toothed sleeve having a feather U to fit in the slot D of the shaft 13, the sleeve being adapted to slide thereon. The shaft B has a segment-rack N, the teeth of which mesh with the drivingpinion M, so that when the quadrant-lever is rotated the toothed sleeve will turn the beveled pinion 0 against or with the sun, according as to which toothed member 11 or n is in mesh therewith, and as the pinion c is secured to the type-segment shaft 0 the type-seg ment will be rotated. The toothed member to the left of the sleeve is normally in engagement with the pinion c, and when the said pinion is turned thereby the type-segment is turned to bring the small letters and figures into printing position. hen the toothed member to the right is thrown in mesh with the pinion, the capitals and punetuationmarks are brought into printing position. The position of the toothed sleeve N is changed by means of a key-lever G, which swings on a stationary stub-shaft G at the side of the machine, the same having a depending arm G and a spring GE to keep it in its normal The arm G is connected to an arm 0 on the end of a slotted reversing-shaft 0, said shaft having a short arm 0 with a feather 0 which is adapted to slide thereon. To the short arm is connected a link 0, the arm and link forming a toggle. To a bell-crank lever o" is connected a link 0 engaging with a keyway or longitudinal recess in the lever 0 such connection forming another toggle. The two toggles are so connected that when one is on dead-center, as shown in Fig. 8, holding the left-hand toothed member a in a normal position the other, at, is off the center, and vice versa, according as to whether a small or large letter is to be printed. The crank-lever o and link 0 have their bearings upon the frame F, which is open at the bottom to straddle the short arm and to act as a spring for the cranklever toggle as a resisting force for the said toggle and sleeve, the spring of the key-lever acting as the resisting force for the other toggle.

The shaft C is provided with a longitudinal recess 0, and within the shaft is a connectingrod 0 secured at one end through the keyway of the hub of the type-segment by a pin 0 and near the middle through the keyway to a loose collar 0, which encircles the shaft C. The other end of the connecting-rod c is formed into a ring to encircle the shaft 13 in order to connect with an extension-arm q". The shaft 0 has a collar 0 to support the same against the frame F, and it has another collar c fixed thereon which is adapted to cause the type-segment 0 through the intervention of the shaft C to receive an independent resistance of a helical spring a in one direction. A similar spring c supplies the resistance for the inner rod, and as the inner rod is eonnected to the type-segment it will shift the segment downward without moving the shaft C and without acting upon the other spring, thereby permitting an independent spring action for each direction of movement.

\Vhen the keyboard is depressed, it will turn the type-segment through the intervention of the mechanism hcreinbefore described, and in order to arrest the turning of said typesegment to bring the characters or type in printing position I employ in connection with the finger-keys I a sliding diagonal or slanted edge-plate l with three deviating edges of the same angle, which plate moves back and forth beneath the keyboard, moving in grooves it, formed by the members if If in conjunction with the keyboard. To this sliding plate are connected rods p p, which extend rearward therefrom and are pivoted at their rear ends to depending arms I1 rigidly connected to the shaft II, carried by the main keyboardlevers. By this arrangement when one of the finger-keys is depressed and the keyboard is lowered by pressure thereon the pinion ll. will be turned by engagement with the segment-rack J, and the quadrant K being conneeted to said pinion by a pawal Z will be turned thereby,this movement continuing until the sliding plate P is arrested by the dcpressed finger-key, when the rotation of the shaft II will be stopped and the pawl thrown out of engagement with the pinion,thus changing the check and swing of the quadrant-lever K from one end to the other and checking the operation of the mechanism which turns the type-wheel and thereby leaving the type corresponding with the depressed key in a printing position.

The quadrant-lever is capable of a change able swinging and checking point operation at each of its extreme ends and is connected at each end to equalized springs, its rear end held in check to a rack J and connected thereto by a pawl through a pinion, its front end connected to the type-segment and an indicator or governor and adapted to rotate the same, and the quadrant-lever connected by the pawl through the pinion, arms, shaft, and rods to the slanted edged plate P, located beneath the keyboard, and a pawl adapted to maintain the connection by means of springs pulling against one another. The rack'J is adapted to serve as the swinging-point of the rear end of the quadrant-lever K and the teeth of the quadrant-lever as the swingingpoint of its front end. The changeable swing and check operation occurs when the plate P contacts with a key, disconnecting the pawl Z and affecting the quadrant-lever K in such amanner that when one end is checked there- I the finger, lug, quadrant, cam pinion-'wheel,

cord, and ratchet grooved disk to the helical spring, the cam on the pinion-wheel being adapted to equalize the tension of the spring, whereby the changeable equalized spring ac tion will maintain equal resistance for each stroke of the keyboard-lever throughout its entire depression.

It will be noted that when the quadrantlever K ceases to turn the pinion M the tension of the spring m, which acts on the front end of the quadrant-lever, is relieved, and in order to continue the same tension throughout the depression'of the keyboardI provide a supplemental tension device consisting of a stub-shaft R, supported by an arm R, pro jecting from a collar R loosely mounted on a rock-shaft at the right-hand side of the machine, and said arm is provided at its rear end with an apertured lug r, with which engages a finger h ,.projectin g from the arm'I-I rigidly connected to the shaft H, forming a pivoting-point.

Upon the stub-shaft R is loosely mounted 'a pinion R in mesh with'a stationary rack J secured to the bed-plate'A, and to the pinion is attached a quadrant R the teeth at the front end of which mesh with the pinion R attached to a disk or wheel R having an involute or cam R forming a cam pinionrant R and pinion R are held upon the stubshaft R by means of a collar r The tension fore mentioned, for when the shaft H is rotating the shaft R will remain stationary.

An even movement of the keyboardis provided for by means of racks h' hflwhich project from the members H H of the main keyboard -lever and mesh with pinions 7L5 7L5, keyed to a transverse shaft 11 journaled in suitably-supported bearings.

The mechanism for moving the type-segment and carriage step by step across the machine to provide for the proper spacing of the letters upon the sheet consists of two sheaves U and'U', mounted on a rock-shaft B, one of the sheaves having a handle U The sheaves are connected to each other by a cord or flexible connection a, which passes therefrom around suitable guide-pulleys a, connected at an intermediate point to the carriage, having rollers, said carriage being mounted on the transverse reversing-shaft 0. One of the sheaves is provided with a tension device for equalizing the step-by-step winding movement of a spring during each stroke of the main lever and to return the type-segment at the end of a line of printing, and the same is similar to the tension device used for giving proper tension to the main keyboard-lever and consists of a cord a extending from a spring of, which is attached to a ratchet grooved disk n and connected to a cam 10 to one side of the sheave, which is mounted on the shaft B. It will be understood that in operation the cord to is wound upon one of the sheaves and paid out or unwound from the other and that as the carriage or moving frame is connected to the cord the type-segment and parts carried thereby will be movedback and forth across the machine as the sheaves are turned. In order to move the type-segment step by step as the main keyboard-lever is depressed, the sheave U has a rack-tooth rim W secured thereto, which is engaged by a pawl w,'fulcrumed on a bracket secured to the bed-plate and provided at its forward end with a pawl w which bears against a lug 10 a lever, and having also a projecting portion with which the sliding bar WV engages, said bar being connected to the main keyboardlever by a horizontal member w Fig. 3. The lever 10 is provided with a lug 10 which is adapted to engage the projecting end of the pawl w to trip the same or throw it out of engagement with the rack-teeth of thesheave at the proper time. At the other side of the sheave U is a pawl Z for preventing backward rotation of said sheave when the pawl w is out of engagement therewith. The pawl Z may be pivoted to a bracket secured to the base-plate A, and the pivot-pin also carries a trip-lever Z, having a lug .2, which is adapted to engage the projecting end of the pawl when the said lever is moved by handle or stud U which projects from the side of the sheave U,

the handle or stud being so located that the pawl Z will be tripped to allow the sheaves and cord to move the type-segment back to its normal position after a line of printing has been completed, thus providing an automatic movement for this purpose, and in order to relieve the jar that is likely to occur when the type-segment flies back I may place a cushion in way of stud to receive the impact. It will be understood that the rack-tooth rim \V or sheave U is turned or moved a short distance at each depression of the main keyboard-lever, said lever being connected to the sliding bar \V, which when moved downward bears upon the pawl w and depresses the forward end of the lever IF, the rear end of which carries the pawl 11', that operates the sheave U, and when said lever is tripped at each stroke of the keyboard-lever by the pawl in moving out of engagement with the sliding bar just previous tothe completion of the stroke of the keyboard-lever the projection wwill contact with the projecting end of the pawl w and move the catch portion thereof out of engagement with the rack-teeth, so that the pawl Z will hold the sheave, the said operation producing the step-by-stcp action. The lever w is returned to its normal position by a spring 1r.

l (see Fig. 3) designates a rectangular frame which serves as a support for the typesegment and is adapted to move laterally step by step across the machine, it having crosspieces for the bearings of the type'segment shaft G, and said frame is open at the bottom, so that its sides will form springs for the toothed sleeve N. The bottom ends form bcarin gs fo r grooved rollers f, which are adapted to run on the reversing-shaft O, and the bottom ends of the frame are adapted to straddle short arms 0", so as to cause it to move laterally with the frame, the frame also having eyebolts f for attachment of the cord hereinbefore described. lVithin the shaft B is positioned a sliding shaft E, having a circular groove at one end and connected to the frame by means of a feather b the groove serving to allow the feather to work therein while the sleeve is being rotated with the shaft 3 The said connection is for the purpose of dragging the striking-point c of the hammer with the type-segment, as it is connected to the sliding shaft byan extension-rod E and an arm 8, thus forming a U -shaped slide. The arm 0 carries a grooved roller 6, which is adapted to run on an extension-tube E, which encircles the reversing-shaft O and slides thereon. \Vhen the machine is to be operated, the tube E is drawn outward manually, it fitting tightly within a socket or bearing 6 so as to form asupport for the U-shaped slide. The extension-rod E passes through a stationary or fixed tube S, mounted so as to lie across the machine, and one end of the rod E is bent at right angles and passes through and slides in a longitudinal recess .5 of the tube S, which is adapted to guide the same therein. The rod E is further bent in the shape of the letter U, so as to form a projection or striking-point c and bring it in proper position for striking the type-segment. The rear end of the member 0'' has a projection 15,

adapted to be struck by mechanism as will be hereinafter explained. The stationary or fixed tube S is provided with leafsprings s at each end for holding the paper in a position for printing, and when a line of printing has been completed the paper may be shifted manually.

D designates a disk or controlling wheel which is adapted to be rotated and checked with the type-segment through the keyboard, the disk having openings or spaces and teeth around its circumference, the same being secured at one end of a shaft l), which rotates upon the'rock-shaft 13. The other end of the shaft D has a ratchet-wheel (Z secured thereto, which ratchet-wheel is revolved by a pawl Z). Between the disk D and ratchct-wheel (l, at suitable distances apart, are located two supports (1 d, which straddle the shaft 1) and have apertures to form bearings for guide- rods 1, 2, and 3. The three rods 2, and 3 are adapted to engage the recesses of the disk D, and the uppcrand lower rods are connected to the type-segment while the other or side rod 3 acts as a supplemental tension device. The rods are so operated that when two are checked the other will be brought into play, thereby maintaining equal tension for each stroke of keyboard and regulating shift movement of segment-lever according as to whether the inner or outer section of keys of the keyboard is to be operated upon. he rods having a sliding movement parallel to the shaft D are each provided with collars d and helical springs (7., which are connected to the supports, so that the rods will be kept thereby in their normal positions. The rod 3, which extends beyond the disk D, has a projection on its extreme end, and said rod engages the disk D from its outer face, while the rods 1 and 2 engage or penetrate a recess from the inside at certain times, according as to which key happens to be depressed. llehind the keyboard is located a tube q, which is mounted loosely upon the guiding gear-shaft ll of the keyboard-lever, and said tube has collar with an arm g, to which are connected the upper and lower rods 1 and 2. The tube 1 is adapted to rotate loosely in either direction independent of the shaft II, and the tube (1 has a horizontal arm (1 with a feather or key, and the same is adapted to slide upon the tubular shaft 1 and is connected to the bottom of the internal spindle of the type-segment O for shifting said segment in either direction. The arm q is adapted to be drawn laterally with the type segment, the feather running in the longitudinal recess of the tube, thereby causing the arm to rotate with the tube q. The upper rod 1 is connected to the tube-shaft by arevcrsing changeable check or top lever X through the rods 0; and In, upright shaft 02 arm m forming a bell-crank, and rod :rflwhich' The lower rod 2 is connected to the arm q. is also connected to the tubular shaft (1 by a lever X, having its fulcrum upon a fixed pin m and said lever is connected to the lever X at its middle by a link or. The front ends of levers X X may be termed joints, respectively, of the rods 1 and 2, or swinging-points which are pivoted to the rods, and when the upper rod 1 is checked the front end of lever X will also be checked. Assuming that the upper rod is held in check, then the joint thereof will be checked, and when the lower.

rod is operated upon by the keyboard to penetrate the disk and being pivoted to the lever X will cause the same to swing to the right, and as the lever X is connected by a link x to the reversing-lever X it will cause its middle joint and rear end to swing to the right, and as therear end is connected to the type-segment, as hereinbefore described, it will shift the said segment downward, so as to bring the type of one of the outer rows, as described, in front of the hammer. When the lower rod is in check and the upper one comes into play, the operation will be reversed, for as the lower rod is checked the bottom lever X and the link 00 'will also be checked. When the upper rod is changed to the midle joint, and as the front end of lever X moves to the right its rear end will move to the left, and as the .rear end is.

connected to the type-segment it will shift the same upward. To the side rod Sispivoted the front end of a changeable swing and check-lever Y, adapted to encircle the shaft D, the same being pivoted at its middle to an upright changeable swing and check-lever Y at the side of the shaft D, the top end'of which is pivoted to a projection on the upper rod 1, and its lowerend is pivoted to a similar projection on the lower rod 2. The rear end of the center lever Y is connected to the keyboard-lever through the intervention of:

the rod 11 the upper arm y, upright shaft g and lower arm g forming a bell-crank, rod 3 and arm 3 secured to the guiding-gear shaft H andas the guiding-gear-is operatedby the keyboard-lever the arm 3 will strike the rod y, and it will transmit the movement The check of thejoint.

front end of lever Y will also be checked,

and as the rear end of lever Y is moved to the right when acted upon its middle joint will act upon the upright lever Y, and asthe bottom end has been checked, as stated, the top will come into play, and as the top end is pivoted to the upper rod it will transmit the movement to the type-segment in one direction, and, again, when the upper and side rods'are held in check the top end of the upright lever will also be checked, and when the same operation of lever Y occurs it will move the lower rod and therefore transmit the movement to the type-segment in the opposite direction, presenting the other outer row of type. Therefore the check of the upright lever Y has been changed from top to bottom. Again, when the upper and lower rods are held in check the top and bottom ends of upright lever Y and the middle joint of the center lever Y will also be checked, and when the rear end of the center lever is acted upon to move to the right and its middle joint being checked, as described, such action will cause the front end of the center lever Y to move to the left, the projection of the side rod penetrating the disk from the outside and the rod acting upon the helical spring as to supplemental tension. The typesegment is therefore not shifted in this third operation and the inner row of type will re- 'main presented in a printing position, the

check of the center lever Y having been. changed from the front end to the middle The rods are so situated in relation to the teeth and openings in the disk that aline drawn from the center of one rod end to the other would form, a triangle, two of the sides being equal, the position of the rods deviating in relation to the openings, so that when one rod is directly opposite an opening,- such as the side rod 3 in- Fig. 5, the other two will come opposite a tooth at different points of contact or striking points, as shown in dotted lines.

To the upright shaft y is secured an arm T, having an arm t, adapted to bring the striking-point e of the hammer against thetype through the intervention of a rectangular swinging frame T, forming a portion of the rock-shaft B. The frameis shown in dotted lines in Fig. 1, and the same frame strikes the hammer at different points of contact on the frame as said hammer movesstepby step across the machine. a At each side of the machine, at its rear end, are located two ribbon-rolls V V, which are adapted to revolve upon the upright shaft .22 and 3 each roll having handles 1;, which may be used to turn the same manually, the rolls carrying an inking-ribbon n, which passes around pins v The ribbon lies across the:

machine between the type and thepaper, and when a line ofprinting is completed the ribbon is wound from one roll to the other sufficient for another line of printing. If desired,

the pins it maybe placed upon the swinging frame T, so that the ribbon will move there with.

In operation the type-segment is normally held so that a middle type of the inner row is opposite the hammer-point and one of the gears of the sleeve is held normally in engagement with the pinion of the type-segment.

Assuming that a small letter of an outer row is to be printed, the operation is as follows: After the telescopic support has been extended the operator moves the auxiliary lever Z, releasing its pawl from the sheave, so that the typesegment may assume its nor mal position at the left of the machine. A fingerkey of one of the outer rows first moves the stem thereof in the path of the sliding plate 1 and its downward movement with the keyboard will rock the levers 11 ll and move the shaft 11' upwardly. The pinion II thereon, engaging the tooth-rack J and being engaged by the pawl I, will turn said shaft, as well as the quadrant-lever K, which, being in mesh with the driving-pinion M, will turn the type-segment in one direction through the intervention of the shafts and tooth members, the driving-pinion also turning the disk D through the intervention of the pawl and ratchet-wheel b. When the sliding plate has reached the depressed key, its movement will be arrested, throwing the pawl I out of engagement with the pinion 11, thereby releasing the hold of the quadrant-lever from the rack J and changing its check from the rear end to the front end and the swing from the front to the rear end, thereby checking the type-segment and bringing the type of the outer row corresponding to the depressed key in way of its printing position ready to be shifted. The checking operation of the quadrant-lever will also check the disk D, so as to bring any opening directly opposite an outer rod, (which is either an upper or lower rod,) the said quadrant-lever will also hold in check the resisting force acting 011 its front end and act upon the other resisting force applied to its extreme rear end transmitted from the other side of the machine. At the same time during the depression of the keyboardlever the feed-lever 10' is being acted upon through the intervention of the sliding bar \V', so as to move the type-segment and hammer through the sheave and its pawls for the spacing of a letter or character. At the time when the keyboard lever has nearly completed its stroke the feed-lever to will have swung itself out of engagement with the sheave and sliding bar by means of the lugs to and 21"", the auxiliary pawl .2" holding the type-segment against its step-by-step resisting force. At the same time the arm 7 011 the shaft 11 will have struck the rod 1 acting upon the disk D or tooth-wheel mechanism and transmitting the movement to thelower rod,and thence to the type-segment, moving it downward and bringing the desired type of an outer row into its proper printing position. The required movement is also transmitted to the hammer through the intervention of the swinging frame T in order to make an impression of the type upon the paper, and the complete depression of the li'eyboard-lever holds the hammer against the paper until it begins its upward movement, during which time the sliding bar \V will again engage itself with the feed-lever ready to repeat the same operation when a word has been printed, the space that follows, to separate itfrom the next word, is produced by the depression of any part of the keyboard without the use of the keys, the mechanism will be actuated, but the type-segment will present ablank. Therefore no impression will bemade. \Vhen aline of printing has been completed, the stud of the sheave will strike the auxiliary lever Z, releasing its pawl and returning the type-segment to its normal position to commence another line of printing.

\Vhen a character of the inner row of the type-segment is to be printed, the inner keys are operated upon, but the shifting operation of the type-segment is not effected, the side rod penetrating the disk I), so as to substitute a resistance in order that equal tension may be maintained for each stroke of the keyboardlever. \Vhen a capital letter is to be printed, the independent key-lever G is depressed, thereby changing the gear through the intervention of the toggles in order that the turning movement of the type-segment may be reversed, at which time the same operation is repeated.

The depression of a finger-key first moves the stem thereof in the path of the sliding plate P, and its downward movement with the keyboard will rock the lovers If it and move the shaft II upwardly and the pinion H thereon, engaging the toothed rack J and being engaged by the pawl Z, will turn said shaft, as well as the quadrant-leverK, carried thereby, which being in mesh with the driving-pinion M will turn the type-segment in either direction through the intervention of the segment, intermediate shaft, and bevelgears, according to which toothed member is in mesh with the type-segment, the movement of the type-segment being checked at the proper time by the sliding plate 1 engaging the depressed key to throw the pawl I out of engagement with the pinion 11?, thereby changing the swing and check from one end of the quadrant-lever to the other and cause the tension of the main lever to be taken up by the supplemental tension device, as described. The complete depression of the keyboard lever operates the rock shaft through the intervention of mechanism, including arms and rods, said connection holding the hammer retracted until the main keyboard-lever begins its upward movement. \Vhen the hammer is projected, it will cause contactof the type with the paper, which has been placed in proper printing position. The

depression of the-main keyboarddever also operates therack-teethto feed the type-segment laterally one step through the intervention of the sliding bar W, which is connected to said lever and actuates the pawl w, this operation occurring previous to the operation of the hammer and simultaneous with the movement of the type-segment to bring the character corresponding with the depressed key. in properprinting position. This operation is. repeated until a line of printing is com: pleted, when the stud U of the sheave U trips the lever Z anddisengages the pawl Z, so as to allow the type-wheel to fly back in position to commence another line, the paper being shifted or moved manually. T

The keyboard and certain operative mechanism should be constructed of light material for an easy movement, and I therefore prefer to makesuch parts of aluminium.

It willbenoted. that the type-segment is mounted on a shaft and slides thereon when it is shifteddownward. The rod, being connected to its hub, pulls it down by means of the arm g and acts upon the lower spring, its shaft remaining stationary, and during the upward shift the arm g pushes both shafts upward through the bevel pinion, which has a keyway, the arm acting upon the upper spring only, said springs being adapted to hold the segment in its normal position.
