- This invention relates to that class of typewriting machines in which pivoted type-bars are each provided with a plurality of type or characters arranged longitudinally thereon and each bar operated upon through the medium of a plurality of finger-keys, one for each character, and one or more of which impart to the type-bar a motion around its pivot and longitudinally or in the direction of its length to bring the desired character to the point of printing or impact upon the platen.
- Machines of this general class are shown in the patents to Burridge, Nos. 585,838, 593,563, andv 59%,777.
- a machine more intimately allied in details of construction to that herein described is also shown in a patent to us, No. 610,400, dated September 6, 1898, and upon which the invention of the present specification is in its main features more particularly an improvement.
- each type-bar is equipped with a sleeve having three type-carrying faces, upon each of which a series of type is arranged longitudinally, three type being shown upon each such face.
- Each typecarrying sleeve may be partially rotated at will to bring the type or characters upon either of its three surfaces opposite the platen in proper position to print when the lever is operated.
- Three keys are shown for each lever, and each key when depressed brings to the printing-point the corresponding character upon that face of the type-carrying sleeve then opposite the platen.
- the invention consists, primarily, in two features-first, the organization by which a type-lever is actuated to bring either of three characters then opposite the platen to the printing-point upon the platen, and, second, the organization relating to the partial rotation of the sleeve or part of the type-bar having thereon the type or characters to' be printed.
- the organization by which the three keys of each type-lever effect the three phases of movement of that lever is not dependent upon the organization relating to the partial rotation of the type-carrying sleeves or parts, nor is the latter organization dependent upon the former.
- the key mechanism may be used with a different organization for bringing different series of type or characters opposite the platen, and the latter mechanism may be employed in machines having a different key mechanism from that herein shown.

- each type-bar there is a vertical plate 1, pivoted at its lower end in the bed-plate and having in its enlarged or widened upper described.
- the keys 5 .7 carry laterally-projecting lugs or studs 5 7 which when the keys and other parts are in their normal inactive positions, as shown in Figs. 1 and 2, occupy the ends of the slot 2.
- the lugs 5'7 act as stops to limit the rise of the keys 5 7 and also when both these keys are inactive as stops to prevent motion of the plate 1 about its pivot.
- the central key 6 may have a cross-pin 6 engaging the under face of the top plate to limit its upward movement.
- the keys may be constructed in any desired manner. As shown, each has at its lower end a lateral projection with an aperture through which passes a vertical pin 8, fixed in the bed-plate, a coiled spring 9, surrounding the pin, being interposed between the lateral projection of the key and the bedplate.
- Each type-bar 10 may be constructed in any suitable manner of one or more pieces and is pivoted at 10 in the rear end of a horizontal bar or plate 11, pivoted at 11 on the plate 1 and pivotally connected at its front end to a vertical bar 12, rocking upon a pivot 12 in the bed-plate.
- a horizontal bar 13 is pivoted to the bar 12, and at or near its rear end the bar 13 is connected by a swiveling link 14L with a projection on the type-bar adjacent to its pivot.
- the rear end of bar 13 is guided in a vertical slotted guideplate 15, and the front end of the bar 11 has an upwardly-extendin g projection similarly guided in a slot in a horizontal plate 15.
- the horizontal bar 11 is formed with a hook 16 at its upper edge, the vertical part of which extends across the slot 2 and the horizontal part above the lug or stud 5.
- the upper edge of the hook works in a slot in a transverse slotted rod 17.
- the mechanism may be guided and braced against lateral strains.
- Each key near its lower end has a foot or projection 18, extending above a pin or stud 19, projecting laterally from the bar 13, and the bar 13 extends over the transverse bar 20, which is the universal bar of the machine, and controls the carriage and ribbon feed, as hereinafter described.
- each type-bar 10 is angularly displaced or bent with reference to a horizontal plane to bring the letters or characters thereon to the proper printing-point on the platen.
- the axis of the pivot 10 of each type-bar is at such angle to the axis of the platen-roller as to cause the characters on the type-bars to properly converge on the printing-point when the bars are actuated to take an impression. This may be conveniently accomplished by deflecting the rear ends (those nearest the platen) of the bars 11 on each side of the central one to which the central type-bar is pivoted. This is well understood and is shown in Figs. 1 and 17.
- Each type-bar carries at its outer end a rotatable sleeve 21, mounted thereon in any suitable manner and having three faces marked A B 0, each of which carries three characters, longitudinally arranged and arbitrarily marked a b c.
- the back of each sleeve is formed with gear-teeth 22, adapted to mesh when the type-bars are in the normal elevated engagement with the notched plate 25.
- a pivoted latch 24 is adapted to engage with either of three notches in a plate 25, secured to the end of the sleeve, and has a prolonged end 26, on which bears a spring 27, that tends normally to throw the latch into
- the rack 23 is curved and is mounted, through the medium of slots and set-screws 23 or in any suitable manner, upon a bracket or part 29 of the frame, also preferably curved. Below the rack is mounted a slotted type-bar-guidin g plate 30.
- This plate is preferably curved reversely to the rack 23 and has a series of slots, one for each type-bar, which are flared or widened at their outer ends and closely fit the type-bars at their inner ends, so that as a type-bar rises it is sure to enter its slot and be accurately guided to bring the gear-teeth thereon into operative engagement with the teeth upon the rack 23.
- the guide-plate 30 is fixed at 31 .upon the bracket or part 29 of the frame.
- This general operation is disclosed in our application above referred to, and the present invention relates to improved means for operating the rack, means for locking the type-bars while the sleeves are being partially rotated, and means for releasing the sleeves to permit of their partial rotation and locking them in either of their three positions.
- the locking of the type-bars may be accomplished in a variety of ways without departing from the principles of this invention.
- the specific form in which this part of the invention is embodied consists in a locking-comb 33, having curved or hooked teeth 34, forming recesses, one for each type-bar.
- This comb is curved to correspond to and is mounted upon the slotted type-bar-guiding plate 30, so as to move endwise thereon in any suitable manner, slots and set-screws 35 being shown.
- the sleeve-shifting rack 23 is to be operated, as hereinafter described, the lockingcomb is caused to move endwise in the direction of the arrow, so that its curved teeth will embrace and firmly hold the type-bars.
- the sh ifting-rack 533 is then operated to bring either face B or C of the type-bearing sleeves opposite the platen,and then the locking-comb recedes to release the type-bars and permit their operation through the medium of the finger-keys, as already described.
- the typebearing sleeves may be frictionally or otherwise mounted upon the type-bars, so as to yield to the stress of the shifting-rack and remain in any position into which they may be removed thereby. It is preferred, however, to positively lock the sleeves, and this is accomplished by providing upon the lock ing-comb 33 a series of upright pins or studs 36, each of which engages the tail or extension 26 of a locking-latch 24:, when the locking-comb is moved in the direction of the arrow to lock the type-bars.
- Two shifting-keys 37 38, Figs. 3 and 4 mounted and equipped with returning-springs similarly to the finger-keys 5 6 7 and preferably located at the left of the keyboard, have, respectively, laterally-projecting pins or lugs 37 38, each working in the slots of two vertical adjacent parallel plates 39 40, rocking on pivots in or on the bed-plate.
- the plate 39 has a horizontal slot 39, opening at its ends into downwardly-extending slots 39 39 diverging throughout the greater part of their length at a suitable angle from a vertical line passing through the pivot of the plate when in the normal position and at their lower ends converging slightly.
- the plate 40 has also three slots, a horizontal one, 40, somewhat longer than the slot 39, opening at its ends into down wardly-extendin g slots 40 40
- the slots 40 40 first incline abruptly in the same direction, (to the right, as viewed in Figs. 4, 5, and 6,) and are then throughout the greater part. of their length both slightly inclined in a reverse direction, this inclination being abruptly increased near the bot tom of the slots.
- the keys are shown as arranged on opposite sides of the pair of plates, and their pins 37 33 project through the horizontal slots of both plates and normally occupy the ends of the slot 39.
- the upper end of the plate 39 is connected by a pivoted link &1 with one end of a lever 42, fulcrumed at 43 on a brace-bar 44, connecting the brackets 29 and slotted guide-plate 30.
- the upper end of the lever passes through a slot in the bracket 29 and is operatively connected with the endwise-movable rack 23.
- the upper end of the plate 40 is pivotally connected to a bar 44, sliding with sufficient freedom of movement by means of a slot and screw 45 on one of the side bars 46 of the frame and having a laterally-projecting pin 47 extending between the bifurcation of a lug 48 on the locking-comb 33, projecting through a slot in the guide-plate 30, Figs. 4 and 9.
- the pin 37 first rides against the abruptly-inclined side of the upper part of slot 40 and the bar 44 is drawn to the left, moving the locking-comb in the direction of the arrow, causing its curved or hooked teeth to embrace the typebars and its lugs 36 to lift the latches 24 out of engagement with the type-carrying sleeves.
- the pin 37' does not produce any further movement of the plate 40, because the central part of the slot 40 is now vertical, but'it acts upon the inner edge of the inclined slot 39 and rocks the plate 39 to the right, thus causing the rack 23 tomove endwise and partially rotate the type-sleeves to bring one of its side type-bearing surfaces opposite the platen.
- a spring 49, Fig. 9, may be applied to the bar 44, that operates the locking-comb and tends to return the lockingcomb to its normal position.
- a centering or truing pin 50 On each typebar adjacent to the type-bearing sleeve is a centering or truing pin 50, which enters either one of three guide-sockets in a block51, arranged adjacent to the platen 52, Figs. 1 and 10.
- Figs. 15 and 16 show a slight modification of the latch for locking the type -bearing sleeve.
- the latch 24 is straight and rocks in a single plane parallel with the axis of the sleeve and is operated on by the inclined face 36 of a stud carried by the locking-plate 33.
- Figs. 13 and 14 show another modification.
- the plate 25 at the end of the sleeve is provided with three apertures 25, whose axes are parallel with the axis of the sleeve.
- a locking-pin 25 sliding endwise in a bearing on the type-bar has an angular end 25 working in an inclined slot in a lever 25
- a lug or projection on the locking-comb 33 operates the lever to withdraw the pin from one of the apertures, while a coil-spring returns the lever and locking-pin to the normal position when the locking comb 33 recedes.
- the screw that forms the pivot of the lever may also, as shown, be the centering or truing pin 50.
- the platen or cylinder 52 is mounted in standards near the ends of the carriage 53.
- the carriage may slide in seats or Ways in two lines of posts 54, mounted on the bedplate and be held thereon by strips or plates 55. Any suitable arrangement or style of platen and platen-carriage and means for actuating them may be adopted. Posts projecting from the bottom of the carriage carry theratchet-plate 56. Any suitable arrangement of spring or weight tends to propel the carriage from right to left of the machine, as usual, none being shown in the drawings.
- the latch rocks on trunnions 57 having bearings in adjacent posts 54 of the inner row or series of such posts, and at its front end 5'7 is pivotally connected to a short link 58, pivoted to a bar 58, that connects the rear ends of the side bars 59 of the universal bar 20. At a suitable point between their ends these side bars are connected by a rock-shaft 60, having bearings in posts 61, located at ornear the sides of the machine.
- Springs 62 (shown as coiled around the rock-shaft and having their free ends bearing, respectively, against the posts 61 and side bars 59) tend to hold the universal bar 20 against the bars 13 of the type-bar-actuating devices and throw down the rear ends of the side bars.
- Fig. 1 we have merely indicated at X a rocking ribbon-carrier. Any suitable ribboncarrier and ribbon-feed mechanism may be employed, and the invention is in no way dependent upon or particularly related to the ribbon mechanism indicated.
- the slots 3 and 4 might be diverged throughout their length or not convergent at their lower parts, they being then of such length and the pins 5 7 so related to them that on the complete depression of the key the pivot of the type-bar will be brought to the proper position and the type just out of contact with the platen.
- the usual quick impulse given to the key would impart such motion to the type-bar that the momentum of the end of the bar to which it would naturally yield would be sufficient to bring the type against the platen with a sharp impact.
- type-bars having rotatable type-bearin g sl'eeves,each with multiple type-bearing faces, mechanism for partially rotating the sleeves to bring the desired type-faces thereof into the desired position, devices for locking the type-bars and holding the sleeves in'operating engagement with the mechanism for partially rotatingthem,means for first throwing the locking devices into operation, means for then operating the sleeverotating mechanism, and means for then throwing the locking devices out of operation.

TYPE-WRITING MACHINE.
SEPECIFICAIION forming part of Letters Patent No. 620,774, dated March '7, 1899.
Application filed August 19, 1898. Serial No. 688,981. (No model.)
To to whom, it may concern:
Be it known that we, EDWARD B. HESs,0f the city and county of New York, and JOSEPH M. STOUGHTON, of the city of Yonkers and county of \Vestchester, State of New York, citizens of the United States of America, have invented certain new and usefullmprovements in Type- I'Vriting Machines, of which the following is a specification.
This invention relates to that class of typewriting machines in which pivoted type-bars are each provided with a plurality of type or characters arranged longitudinally thereon and each bar operated upon through the medium of a plurality of finger-keys, one for each character, and one or more of which impart to the type-bar a motion around its pivot and longitudinally or in the direction of its length to bring the desired character to the point of printing or impact upon the platen. Machines of this general class are shown in the patents to Burridge, Nos. 585,838, 593,563, andv 59%,777. A machine more intimately allied in details of construction to that herein described is also shown in a patent to us, No. 610,400, dated September 6, 1898, and upon which the invention of the present specification is in its main features more particularly an improvement.
In the machine herein described, as in that of the above application, each type-bar is equipped with a sleeve having three type-carrying faces, upon each of which a series of type is arranged longitudinally, three type being shown upon each such face. Each typecarrying sleeve may be partially rotated at will to bring the type or characters upon either of its three surfaces opposite the platen in proper position to print when the lever is operated. Three keys are shown for each lever, and each key when depressed brings to the printing-point the corresponding character upon that face of the type-carrying sleeve then opposite the platen.
The invention consists, primarily, in two features-first, the organization by which a type-lever is actuated to bring either of three characters then opposite the platen to the printing-point upon the platen, and, second, the organization relating to the partial rotation of the sleeve or part of the type-bar having thereon the type or characters to' be printed.
The organization by which the three keys of each type-lever effect the three phases of movement of that lever is not dependent upon the organization relating to the partial rotation of the type-carrying sleeves or parts, nor is the latter organization dependent upon the former. The key mechanism may be used with a different organization for bringing different series of type or characters opposite the platen, and the latter mechanism may be employed in machines having a different key mechanism from that herein shown.
In the accompanying drawings, Figure 1 is a vertical section at right angles to the cylindrical platen; Fig. 2, asimilarsectionlooking in the opposite direction and showing the key mechanism for operating one of the typebars; Fig. 3, a similar section taken at the side of the machine, showing the shifting keys and mechanism for efiecting a partial rotation of the type-carrying sleeves; and Fig. 4,a view of the same mechanism at right angles to Fig. 3. Figs. 5 and 6 are respectively detail views of pivoted slotted plates operated by the shifting-keys to accomplish the partial rotation of the type-carrying parts or sleeves; Fig. 7, a plan view of a part of the machine, showing the type carrying sleeves and a means for effecting their partial rotation. Fig. 8 is a rear view of the same parts, showing also the device for guiding the type-bars to bring their type-carrying sleeves into gear with the shifting-rack and the locking-comb for holding the typebars while the type-carrying sleeves are being shifted or partially rotated. Fig. 9 is a bottom view showing more particularly the latter device. Figs. 1O, 11, and 12 are detail views showing the type-carrying sleeves and locking-latches to secure them in either position to which they may be shifted or partially rotated. Figs. 13, 14, 15, and 16 are detail views showing modifications of the locking-latches of the sleeves; Fig. 17, a section with some of the parts removed on the line 17 17 of Fig. 1.
For each type-bar there is a vertical plate 1, pivoted at its lower end in the bed-plate and having in its enlarged or widened upper described. For each such plate there are three finger-keys 5 6 7, and the keys 5 .7 carry laterally-projecting lugs or studs 5 7 which when the keys and other parts are in their normal inactive positions, as shown in Figs. 1 and 2, occupy the ends of the slot 2. The lugs 5'7 act as stops to limit the rise of the keys 5 7 and also when both these keys are inactive as stops to prevent motion of the plate 1 about its pivot. The central key 6 may have a cross-pin 6 engaging the under face of the top plate to limit its upward movement. The keys may be constructed in any desired manner. As shown, each has at its lower end a lateral projection with an aperture through which passes a vertical pin 8, fixed in the bed-plate, a coiled spring 9, surrounding the pin, being interposed between the lateral projection of the key and the bedplate.
Each type-bar 10 may be constructed in any suitable manner of one or more pieces and is pivoted at 10 in the rear end of a horizontal bar or plate 11, pivoted at 11 on the plate 1 and pivotally connected at its front end to a vertical bar 12, rocking upon a pivot 12 in the bed-plate. At a suitable point between the pivots 11 12 a horizontal bar 13 is pivoted to the bar 12, and at or near its rear end the bar 13 is connected by a swiveling link 14L with a projection on the type-bar adjacent to its pivot. The rear end of bar 13is guided in a vertical slotted guideplate 15, and the front end of the bar 11 has an upwardly-extendin g projection similarly guided in a slot in a horizontal plate 15. Preferably the horizontal bar 11 is formed with a hook 16 at its upper edge, the vertical part of which extends across the slot 2 and the horizontal part above the lug or stud 5. The upper edge of the hook works in a slot in a transverse slotted rod 17. In these or any other suitable ways the mechanism may be guided and braced against lateral strains. Each key near its lower end has a foot or projection 18, extending above a pin or stud 19, projecting laterally from the bar 13, and the bar 13 extends over the transverse bar 20, which is the universal bar of the machine, and controls the carriage and ribbon feed, as hereinafter described.
As is well understood, each type-bar 10, except the middle one, is angularly displaced or bent with reference to a horizontal plane to bring the letters or characters thereon to the proper printing-point on the platen. Also the axis of the pivot 10 of each type-bar is at such angle to the axis of the platen-roller as to cause the characters on the type-bars to properly converge on the printing-point when the bars are actuated to take an impression. This may be conveniently accomplished by deflecting the rear ends (those nearest the platen) of the bars 11 on each side of the central one to which the central type-bar is pivoted. This is well understood and is shown in Figs. 1 and 17. On the depression of the center key 6 its foot 18, acting upon the pin 19, carries down the bar 13 and the type-bar 10 is thrown to bring the middle type or character Z) to the printing-point on the platen. The parts are returned to normal position by the springs 9 and 13, and no special device is required during the movement of the key to hold the plate 1 stationary, the lugs 5'7 performing this function. If the key 7 be depressed, the same operation occurs, with the addition that a longitudinal movement of the type-bar toward the rear of the machine occurs, so that the letter or character marked 0 is brought to the printing-point. This operation is efiected by the lug 7 passing down the inclined slot 4 in the plate 1, thus rocking the plate 1 upon its pivot and carrying it toward the rear of the machine until the lug enters the reversely-inclined bottom part of the slot, which, however, now stands vertically with the plate in the angular position into which it has been rocked. The movement of the plate therefore ceases, and the continued descent of the key produces the impact of the type upon the platen. During this operation the slot 2 permits the free move ment of the plate 1 relatively to the lug 5 on the key 5. lVhen the key 5 is depressed, precisely the same operation occurs, except that the lug 5 now moves the plate 1 toward the front of the machine, thus imparting a longitudinal movement to the type-bar in the reverse direction, thus bringing the character which is arbitrarily marked a to the printingpoint on the platen. This organization possesses several advantages, among which may be mentioned the positive holding of the plate 1 in its normal position and when the center key is depressed by the devices which cause its operation when the other two keys are depressed, thus giving rigidity and stability to the parts without the employment of any special mechanism for that purpose.
The mechanism relating to the partial rotation of the type-sleeves or parts of the typebars will now be described.
Each type-bar carries at its outer end a rotatable sleeve 21, mounted thereon in any suitable manner and having three faces marked A B 0, each of which carries three characters, longitudinally arranged and arbitrarily marked a b c. The back of each sleeve is formed with gear-teeth 22, adapted to mesh when the type-bars are in the normal elevated engagement with the notched plate 25.
position with the teeth of an endwise-movable rack A pivoted latch 24: is adapted to engage with either of three notches in a plate 25, secured to the end of the sleeve, and has a prolonged end 26, on which bears a spring 27, that tends normally to throw the latch into The rack 23 is curved and is mounted, through the medium of slots and set-screws 23 or in any suitable manner, upon a bracket or part 29 of the frame, also preferably curved. Below the rack is mounted a slotted type-bar-guidin g plate 30. This plate is preferably curved reversely to the rack 23 and has a series of slots, one for each type-bar, which are flared or widened at their outer ends and closely fit the type-bars at their inner ends, so that as a type-bar rises it is sure to enter its slot and be accurately guided to bring the gear-teeth thereon into operative engagement with the teeth upon the rack 23. The guide-plate 30 is fixed at 31 .upon the bracket or part 29 of the frame.
It will be obvious that if the center typebearing faces A of the type-bearing sleeves are opposite or facing the platen they may all be partially rotated in either direction (provision being made for operating the latches if employed) by the movement of the rack, so as to bring either the type-bearing faces B or O opposite the platen. Either type-bearing face of any type-bar being thus brought opposite the platen either character thereon arbitrarily marked a b 0 may be brought to the printing-point at will by the manipulation of the keys 5, 6 or 7. This general operation is disclosed in our application above referred to, and the present invention relates to improved means for operating the rack, means for locking the type-bars while the sleeves are being partially rotated, and means for releasing the sleeves to permit of their partial rotation and locking them in either of their three positions. The locking of the type-bars may be accomplished in a variety of ways without departing from the principles of this invention. The specific form in which this part of the invention is embodied consists in a locking-comb 33, having curved or hooked teeth 34, forming recesses, one for each type-bar. This comb is curved to correspond to and is mounted upon the slotted type-bar-guiding plate 30, so as to move endwise thereon in any suitable manner, slots and set-screws 35 being shown. Normally the free way or unobstructed openings formed by the curved teeth of the locking-comb coincide with the slots in the type-bar-guiding plate, so that the typebars are free to rise to their highest position until they come to the bottom of the slots in the guide-plate. \Vhen the sleeve-shifting rack 23 is to be operated, as hereinafter described, the lockingcomb is caused to move endwise in the direction of the arrow, so that its curved teeth will embrace and firmly hold the type-bars. The sh ifting-rack 533 is then operated to bring either face B or C of the type-bearing sleeves opposite the platen,and then the locking-comb recedes to release the type-bars and permit their operation through the medium of the finger-keys, as already described. The typebearing sleeves may be frictionally or otherwise mounted upon the type-bars, so as to yield to the stress of the shifting-rack and remain in any position into which they may be removed thereby. It is preferred, however, to positively lock the sleeves, and this is accomplished by providing upon the lock ing-comb 33 a series of upright pins or studs 36, each of which engages the tail or extension 26 of a locking-latch 24:, when the locking-comb is moved in the direction of the arrow to lock the type-bars. By this operation the latches are lifted out of engagement with the notches on the type-bearing sleeves, their partial rotation by the shifting-rack being permitted, and on the retrogression or reverse movement of the locking-comb the latches again engage notches on the type-bearing sleeves and lock them positively in their new position. This is clearly shown in Fig. 1, the pins 36 and latches 24 being omitted in other general views for the sake of clearness of illustration.
The means by which the shifting-rack and locking-comb are operated will now be described.
Two shifting-keys 37 38, Figs. 3 and 4, mounted and equipped with returning-springs similarly to the finger-keys 5 6 7 and preferably located at the left of the keyboard, have, respectively, laterally-projecting pins or lugs 37 38, each working in the slots of two vertical adjacent parallel plates 39 40, rocking on pivots in or on the bed-plate. The plate 39 has a horizontal slot 39, opening at its ends into downwardly-extending slots 39 39 diverging throughout the greater part of their length at a suitable angle from a vertical line passing through the pivot of the plate when in the normal position and at their lower ends converging slightly. The plate 40 has also three slots, a horizontal one, 40, somewhat longer than the slot 39, opening at its ends into down wardly-extendin g slots 40 40 The slots 40 40 first incline abruptly in the same direction, (to the right, as viewed in Figs. 4, 5, and 6,) and are then throughout the greater part. of their length both slightly inclined in a reverse direction, this inclination being abruptly increased near the bot tom of the slots. The keys are shown as arranged on opposite sides of the pair of plates, and their pins 37 33 project through the horizontal slots of both plates and normally occupy the ends of the slot 39. The upper end of the plate 39 is connected by a pivoted link &1 with one end of a lever 42, fulcrumed at 43 on a brace-bar 44, connecting the brackets 29 and slotted guide-plate 30. The upper end of the lever passes through a slot in the bracket 29 and is operatively connected with the endwise-movable rack 23. The upper end of the plate 40 is pivotally connected to a bar 44, sliding with sufficient freedom of movement by means of a slot and screw 45 on one of the side bars 46 of the frame and having a laterally-projecting pin 47 extending between the bifurcation of a lug 48 on the locking-comb 33, projecting through a slot in the guide-plate 30, Figs. 4 and 9. If the shifting-key 37 be depressed, the pin 37first rides against the abruptly-inclined side of the upper part of slot 40 and the bar 44 is drawn to the left, moving the locking-comb in the direction of the arrow, causing its curved or hooked teeth to embrace the typebars and its lugs 36 to lift the latches 24 out of engagement with the type-carrying sleeves. In its further descent the pin 37' does not produce any further movement of the plate 40, because the central part of the slot 40 is now vertical, but'it acts upon the inner edge of the inclined slot 39 and rocks the plate 39 to the right, thus causing the rack 23 tomove endwise and partially rotate the type-sleeves to bring one of its side type-bearing surfaces opposite the platen. In the further movement of the pin 37 it runs in the now vertical lower part of the slot 39 the plate 39 remaining therefore stationary, and in the ab: ruptly-inclined lower part of slot 40 thereby producing a reverse or retrograde movement of the locking-comb, which releases the type-bars and permits their latches to again engage the type-carrying sleeves and lock them in their new position. The type-bars may now, while the shifting-key 37 is held down, be operated, as already described, by the finger-keys 5 6 7. When the key 37 is released, the parts return to normal position. On the depression of the shifting-key 38 the same operation of the locking-comb occurs, but the rack now moves in an opposite direction, thus bringing opposite the platen the third or remaining type-bearing faces of the sleeves. A spring 49, Fig. 9, may be applied to the bar 44, that operates the locking-comb and tends to return the lockingcomb to its normal position. On each typebar adjacent to the type-bearing sleeve is a centering or truing pin 50, which enters either one of three guide-sockets in a block51, arranged adjacent to the platen 52, Figs. 1 and 10.
Figs. 15 and 16 show a slight modification of the latch for locking the type -bearing sleeve. The latch 24 is straight and rocks in a single plane parallel with the axis of the sleeve and is operated on by the inclined face 36 of a stud carried by the locking-plate 33.
Figs. 13 and 14 show another modification. Here the plate 25 at the end of the sleeve is provided with three apertures 25, whose axes are parallel with the axis of the sleeve. A locking-pin 25 sliding endwise in a bearing on the type-bar, has an angular end 25 working in an inclined slot in a lever 25 A lug or projection on the locking-comb 33 operates the lever to withdraw the pin from one of the apertures, while a coil-spring returns the lever and locking-pin to the normal position when the locking comb 33 recedes. The screw that forms the pivot of the lever may also, as shown, be the centering or truing pin 50.
The platen or cylinder 52 is mounted in standards near the ends of the carriage 53. The carriage may slide in seats or Ways in two lines of posts 54, mounted on the bedplate and be held thereon by strips or plates 55. Any suitable arrangement or style of platen and platen-carriage and means for actuating them may be adopted. Posts projecting from the bottom of the carriage carry theratchet-plate 56. Any suitable arrangement of spring or weight tends to propel the carriage from right to left of the machine, as usual, none being shown in the drawings.
57 is the feed latch or pawl device engaging the ratchet-plate. As shown in Fig. 1, the latch rocks on trunnions 57 having bearings in adjacent posts 54 of the inner row or series of such posts, and at its front end 5'7 is pivotally connected to a short link 58, pivoted to a bar 58, that connects the rear ends of the side bars 59 of the universal bar 20. At a suitable point between their ends these side bars are connected by a rock-shaft 60, having bearings in posts 61, located at ornear the sides of the machine. Springs 62 (shown as coiled around the rock-shaft and having their free ends bearing, respectively, against the posts 61 and side bars 59) tend to hold the universal bar 20 against the bars 13 of the type-bar-actuating devices and throw down the rear ends of the side bars.
In Fig. 1 we have merely indicated at X a rocking ribbon-carrier. Any suitable ribboncarrier and ribbon-feed mechanism may be employed, and the invention is in no way dependent upon or particularly related to the ribbon mechanism indicated.
The form in which the accompanyingdrawings show our invention embodied has now been described in detail. It is plain, however, that variations thereof may be made in its different parts without departing from the invention or principles of construction and operation. No attempt will be made to point out modifications in the construction 'described, except that it is deemed expedient to refer to the movable plate 1. Of course with some special means for limiting the rise of the keys 5 and 7such, for instance, as is shown in connection with 6the upper wall of the slot 2 may be removed, the primary purpose of the special arrangement of the slots being that the lugs 5 and 7 shall act as stops for the plate and that between the lugs there shall be a slot, passage, or free way for the accommodation of the inactive lug during the movement of the plate. It is also plain that the slots 3 and 4 might be diverged throughout their length or not convergent at their lower parts, they being then of such length and the pins 5 7 so related to them that on the complete depression of the key the pivot of the type-bar will be brought to the proper position and the type just out of contact with the platen. The usual quick impulse given to the key would impart such motion to the type-bar that the momentum of the end of the bar to which it would naturally yield would be sufficient to bring the type against the platen with a sharp impact.
