  • Fig.23 is a detail view of a clip for holding the glass key-top to the key-levers.
  • Fig. 24 is a similar view of a slightly-different form of this clip.
  • the series of type-bars a are arranged converging toward the printing-point, and they are reciprocated by the manipulation of the keys 3, the levers 1 of which are connected by links 12 13 to the bell-crank levers 8 and 9, pivoted to posts 10 and 11.
  • the connection between the type-bars and the upper ends of these levers is made simply by inserting the hooked ends of the type-bars into the openings in the levers, and the type-bars are easily detached. This connection is a direct one, no rivets or pins beingnecessaryin either the lever or the type-bar.
  • the type-bars at their rear ends rest upon cross-rods, the one marked a supporting the upper series of bars, while the bar a supports the lower series of bars.
  • These crossrods extend between the upwardly-extending posts 31 of the cradle-frame 28, which frame is pivoted at 15 to the stationary framework and is adapted upon the depression of the keys 36 at each side of the bank of keys to shift the upperseries of type-bars out of and the lower series of bars into line with the printing-point to change from upper to lower case printing.
  • the type-bars merely rest loosely upon thesecross-rods a and a and these rods, taken with the bellcrank levers connected to the type-bars at their frontends, constitute the sole support of the said typebars.
  • the rear heads of the type-bars lie in a group between the converging sides 53 of the type-guiding frame, which is carried directly by the cradle-frame instead of independently, as before.
  • the sides 53 of the frame are extended forward far enough to include between them the rear ends or heads of the type-bars, so that Whenever a type-bar is moved it will be guided by this frame toward the printing-point.
  • the shift ing tongue 55 used in my former patents I employ in the present case; but in this instance I mount it loosely upon the cross-bars a a of the cradle-frame.
  • the converging sides 53 53 are sufficiently far apart to permit a loose assembling of the type-bars, so that free lateral play will be allowed and all possibility of the type-bars sticking will be rately into its place.
  • the proper lateral guiding of the type-bars is insured by the converging sides 53 53 of the guiding-frame in connection with the shifting tongue, as above indicated, and the guiding in a vertical direction is afforded by the converging upper and lower walls 53 53 of the guiding-frame.
  • the upper wall 53 is extended forwardly in the form of a cover 53 for the guiding-frame, and this cover confines the type against vertical displacement or jumping out of place, while at the same time allowing sufficient vertical play to insure perfect freedom of movement of the type-bars.
  • the type-bar slides freely and loosely over the crossbar a or a and it can have both lateral and vertical play within certain bounds until the head of the type-bar strikes the converging walls of the guiding-frame and the side of the shifting tongue, when the bar will be directed accu-
  • the converging guiding sides 53 are flared at 53 to provide additional room laterally for the type-bars.
  • the cover 53 is pivoted to the guiding-frame, the pivots passing through ears 53, struck out from the converging guiding-walls, Figs. 1 and 7, and through ears on the cover.
  • the cover is held down in place by its spring-arms 53*, which have indents to engage depressions in the outer sides of the guiding-frame. By this cover access may be had to the type-bars for cleaning, and the type-bars may be lifted up and removed from the machine.
  • the shifting tongue has elongated openings to receive the cross-rods a 0. while an upper circular opening in the tongue engages the upper rod, this construction affording sufficient looseness for the free working of the shifting tongue.
  • the guiding-frame has a pivotal action independent of the cradle-frame. Its converging sides 53 are extended forward outside of the posts 31 and are pivoted on the extended ends of the crossrod a, springs 1) serving to hold the frame normally up opposite the printing-point by drawing down upon the hooked forward extensions 1) of the frame. The lower ends of the springs are attached to the cradle-frame, Figs. 2 and 3. By pressing down upon the rear end of this type-bar-guiding frame the printing-point and the last letter printed may be fully exposed, and then by removing the pressure the guiding-frame will rise automatically to normal position. The movement of the guiding-frame is stopped by a projection O thereon engaging an adjustable washer or disk d, Fig. 3. A lug 164:,
  • Fig. 18 on the opposite side of the frame from that shown in Fig. 3, limits the downward movement of the type-bar-guiding frame.
  • the top plate of the guiding-frame carries the guides cl e'for directing the ribbon from the spools 77 in front of the printing-point.
  • the depression of the guiding-frame thus serves to lower the ribbon from the printingpoint, and no separate carrier is needed for the ribbon, the pivoted guide-frame answering all the requirements as a ribbon-guide and displaceable support.
  • the pivot-posts 10 11 of the bell-crank levers are carried by the cross-bar 15 of the cradle-frame, and the arms 35 connect this cross-bar with the keys 3b.
  • the keys 36 are placed under variable tension through the springs 25, the links 26, and the screws 27, Fig. 2, at the front of the machine.
  • the movement of the cradle-frame is limited by disks 50, adj ustably carried by screw-studs depending from the arms 35 of the cradle-frame, said studs passing through openings in the combplate 48, so that the disks can strike upon the upper and lower faces of the said plate.
  • a 1ocking-lever 38, Fig. 2 is used to hold the cradle-frame in position for printing with upper-case type.
  • the forward end of the lever is thrown up and to the rear the curved end (shown dotted in Fig. 2) will engage the lug 38 on the cradle-frame and tilt the same.
  • the finger pieces or keys are secured to the upturned ends of the key-levers by the sheetmetal shanks f of the keys, Fig. 17, being bent around the reduced ends of the keylever.
  • the carriage of the platen is of special construction. As shown in Fig. 14:, it comprises one piece of sheet metal struck up to provide the end frames or brackets 85 and the horizontal connecting-bars 86, leaving an open center g. One edge of the forward bar 86 is turned up for strengthening the frame, as shown at h. The frame also has a number of ears struck up thereon for supporting the parts hereinafter referred to.
  • the platen K as shown in Figs. 6 and 8, has a plurality of flat faces, and it is supported by the upturned end frames 85. One frame has a notch i to permit the removal of the platen-journal,said journal, in Fig.
  • I provide two sets of pressure-rollers in the present construction, one set 92, Figs. 2, 4, and 8, being carried by a shaft 01, supported by arms 0, pivoted on a cross-rod p of the carriage-frame, said arms being under tension of the springs 29, connected with links 19 which are adjustable by the screws p carried by the rear bar of the paper-shelf.
  • the other set of rollers 92, Figs. 2, 4, and 11, are carried by small frames q, pivoted on a shaft 91*,
  • the frames (1 are of channeled form, and the rollers are journaled in their sides, which are bent up from the main portion.
  • the paper-scale 94 (designated as such in Fig. 9) is carried adjustably on arms 9 1, pivoted on the cross-rod of the platen-carriage, and the scale is pressed against the platen by the spring 95, held by loops 95, pressed out of the paper-shelf, Figs. 2, 4, and 9. .
  • the paperscale may be adjusted by the slot-andscrew connection, as indicated in Fig. 9.
  • the paper-clips 91 are supported slidably by engaging the rear bar of the paper-shelf and also by engaging the cross-rod of the platencarriage, for which purpose the clips, which are made of sheet metal, are struck up with cars 92 to engage the cross-rod.
  • the line-space mechanism is substantially the same as that disclosed in my former patentwith the few exceptions hereinafter noted.
  • the ratchet-wheel is adapted to be engaged by the pawl 100, pivoted to the frame 105, which is journaled on the cross-rod of the platen-carriage, a spring 107 being used to hold the pawl to its work.
  • the frame 105 is operated from the line-space key through the key-lever 1 tat, the link 14%, the lever-arm 145, and the rock-shaft 146, which has leverarm 146 projecting rearwardly therefrom, so as to project under the front bar of the frame 105, so that when the key is depressed the frame is operated to lift the pawl and turn the platen.
  • the shaft 146 is simply arranged by having its journal-pins, Figs. 1 and 10, dropped into open sockets 1', formed on the posts 71, which support the ribbon-spool shafts. The shaft is held from displacement by clips 8 reaching thereover.
  • the line-space regulator 117 is struck up and bent into shape from a single piece of sheet metal. It is journaled on the shaft of the platen and has; a guard-117 arranged when the regulator is, adjusted rearwardly to shield a portion of the ratchet-teeth from the stroke of the pawl 100, so that only a part of the pawls move-j ment will be effective in turning the platen,
  • an ear 109 is formed for the lever 109, as in Fig. 14.
  • a stop 109 is also formed on the platen-carriage for the lever 109.
  • the detent for the platen consists of a spring-pressed lever 15, carrying a roller i to bear on the ratchetteeth. This lever is carried by a stud 163, held by the nut 163 in the slot 85, Fig.
  • the arm 15, which carries the roller i can be moved backward or forward in order that the flat surfaces of the roller may be brought parallel with the type-face-that is, the roller i bearing on the points of two adjacent teeth determines the position of the platen-roller, and if this roller is positioned to the front or back the flat face of the roller (see Figs. 8, 9, and 11) can be made to assume vertical position.
  • the escapement mechanism is substantially like that disclosed in my former patent, consisting of the two pawls 131 132 and the wiper 135 with its inclined edge bearing on the pins 133 13-1 of the pawls.
  • the wiper in the present instance is pivoted to an ear cast on the supporting-bed of the carriage, and it is connected with the arm 141 of the rock-shaft 142 by a link 143 instead of being operated by direct contact with the said arm.
  • the rock-shaft is operated through the lever 142 thereon from the bar 1 12, extending under the key-levers.
  • the pawl 132 is normally in engagement with the rack, while the pawl 131 is normally out of engagement, being held so by its pin 133, resting on a high part of the wiper, while the pin 134: of pawl 132 rests on the low part of the wiper.
  • the pin 134 will ride up on the inclined edge of the wiper, lifting the pawl 132, and at the same time the pin 133 will ride down toward the low part, so that it will engage the rack when the same is free from the pawl 132.
  • the wiper returns to the left, the pawl 132 falls and the pawl 131 rises.
  • the points of the'pawls are so positioned in relation to each other and the teeth of the rack as to give the step-by-step movement to the carriage.
  • the tension on the keys is varied by a spring 135 connected to the wiper-arm 138, the other end of the spring being carried by a sliding pawl 1 17, adjustable in a slot in the back plate 126 of the machine, the lower edge of the slot being toothed and the sliding pawl having a tooth 126' to engage the same.
  • the sliding pawl is provided with studs 126 fitting on the inner and outer sides of the back plate to guide it in its movement, and by raising the finger-piece 127 the sliding pawl is lifted out of engagement with the teeth and may be inovedin either direction to increase or decrease the tension on the keys.
  • Thisarm also has a horizontal extension 131 in the path of stops to, carried on the cross-rod of the platen-carriage between the ears of the paper-clips, so that the paper-clips will be prevented from crossing the printing point by the stops striking this extension.
  • the stops also act as the means for arresting the movement of the carriage to the left by striking the extension.
  • I provide an arm 161 on the rockshaft 142, extending rearwardly into proximity to the hooked end of a lever U, which is pivoted to the comb-bar 4.
  • This lever has a weighted end which holds its hooked end out of line with the arm 161, but when the carriage reaches a certain point the finger w on the carriage engages the spring extension X of the locking-lever and moves the hook over the arm 161, so that this arm cannot rise, and consequently the key-levers cannot be operated.
  • the weaker spring X is caused to deflect,and upon the arm 161' being released the tension of the spring X causes the catch U to snap over the arm 161 and prevents its rising, and consequently stopping the keys from being depressed.
  • the finger w is pivoted to an ear g, which is struck out of the paper-clip. When, therefore, this paperclip reaches the printing-point, the keys will be locked to prevent further printing.
  • the fingerw also operates the bell-hammer w, Fig. 4, which is pivoted at 102 to the bracket 10
  • the spring-drum 128 is connected with the carriage by a band 128 which has a loop at its end to engage a hook 128, struck up from the carriage-frame.
  • This loop 128 is secured on the end of the band by a sheet-metal clip 128 Fig. 20, which is of T form, the part a guided to the spring-drum through a bracket or guide 128, which is formed of sheet metal, with a guide-opening at one end, the other end or foot being secured to the cross-bar on the carriage-bed.
  • the carriage-return mechanism is substantially the same as that formerly used by me, consisting, essentially, of the arms 121 having finger-pieces and connected with a rock-shaft 121, which has a depending arm 120, connected by a link with the bell-crank 119, pivoted under the machine-frame, the long arm of'said bell-crank extending to the rear and being connected through a link 122 with an arm 115, connected with the rack-bar of the carriage.
  • the means for winding up the spring-drum consists of a disk 124:, having a roughened periphery to be grasped by the thumb and fingers, and a ratchet 125 and pawl 127.
  • the disk fits closely to the back plate, and the arm 115 can move across the rear face thereof.
  • the type pass through the wire shield 30 when they leave the guiding-frame, and this shield keeps the ribbon off of the platen.
  • the pivot-posts 10 11 of the bell-crank levers are, as shown in Fig. 19, knurled at their lower ends, thusvproviding a series of longitudinal corrugations, and these posts are simply forced into the cross-bar 15 of the cradleframe.
  • This same method of attachment is employed between the lower end of the spoolshaft 71, Fig. 3, and the miter-gear 141, and it is found that this connection is strong and obviates entirely the necessity of using pins or other fastening means.
  • Fig. 19 The pivot-posts 10 11 of the bell-crank levers are, as shown in Fig. 19, knurled at their lower ends, thusvproviding a series of longitudinal corrugations, and these posts are simply forced into the cross-bar 15 of the cradleframe.
  • the springs c which act upon the type-levers, are held by an inverted-U-shaped bar 142 Within this bar another bar 142' is placed, with its open side uppermost, and the right angular extensions of the springs project through these bars. This construction gives an extended bearing to the springs, so that they will be prevented from tilting or turning under pressure.
  • the key levers at their rear ends are notched, and they engage the comb-bar 4:, a stop-rod X extending under the said rear ends to insure the properposition of the levers.
  • the ribbon-spools are of special construction. As shown in Figs. 21 and 22, they comprise sheet-metal heads (1, which are struck up with flanges e, and fiat portions f, the latter forming rests or bearings for the sheetmetal back plates 9, which are dished or bent at their edges, and the flanges e are turned over into engagement therewith.
  • a spring-ring 7c is placed, through which extends the end of the sheetmetal sleeve 71, which connects the heads, said sheet-metal sleeve fitting with its main part within an opening in the metal backing portion and having a shouldered bearing against the spring-ring which determines the relative location of the parts.
  • the sleeve has its reduced ends extending through openings in the sheet-metal heads, and these projecting ends firmly engage said heads, thus securely binding the parts together.
  • the ring serves to space the disks of the spool the proper distance apart and to afiord a shoulder for riveting over the end of the tube or sleeve, by which riveting the sleeve and head are connected.
  • the sleeve itself is formed of sheet metal pressed into cylindrical form, and this provides a split cylinder which will hold to the spool shaft or spindle by its friction, and this frictional hold on the spindle is increased by the spring portion I, struck up out of the sleeve.
  • the position of the ribbon-spools on the spindles is determined by spring-riug stops m, fitting in grooves in the spindles. This forms a simple stop and may be used at other points on the machine.
  • the shifting tongue is formed of two thicknesses of metal, which are brought together so that the two lips of these thicknesses are broughtinto contact. I prefer to make these two metal parts of different thicknesses, so that the sound-wave lengths will be different and the vibration of one will neutralize the vibration of the other. This has the effect of deadening the sound by "destroying all ringing effect. As shown in Fig. 7, I may make the two thicknesses of metal forming the tongue by folding the metal back upon itself, one half of the metal piece being thinner than the other. This same principle is carried out in connection with the converging walls and cover of the type-guiding framethat is, the guide-frame is lined with a thin sheet of metal 55, as shown in Fig. 7--and this has the effect of deadening the sound.
  • the clip f As shown in Fig. 23, the clip f, previously mentioned, which holds the key tops to the key-levers, is provided with two spurs or projections f, which are embedded in the glass key top, the said glass being cast into connection with the said spurs.
  • the clip has also a turned-over lip f which prevents the glass from running down into the slot of the clip.
  • the lower split portion of the clip embraces the upturned end of the key-lever, and thus holds the key tops securely thereto.
  • I claim- 1 In combination in a type-writer, the converging type-bars, the levers connected with the bars at their front ends, the support for the rear ends of the bars holding the same to permit lateral and vertical play, said bars bearing against each other laterally and loosely and a guiding-frame having converging walls to direct both the vertical and lateral movements of the type-bars to the printing-point, substantially as described.

SPECIFICATION forming part of Letters Patent No. 652,207, dated June 19, 1900.
Application filed October 12, 1897. Serial No. 654,968. (No model.)
To alt whom, it may concern:
Be it known that I, BERNARD GRANVILLE,
a citizen of the United States, residing at Providence,Providence county,Rhode Island,
have invented certain new and useful Im- .provements in Type-Vriters, of which the following is a specification.
My present invention is an improvement upon that form of type-writer disclosed in IQ Patent No. 570,433, dated October 27, 1896,
and while I have adhered in the present machine to the general principle of operation as disclosed in said patent I have greatly simplified the construction and lessened the nu mher of parts.

5 The series of type-bars a are arranged converging toward the printing-point, and they are reciprocated by the manipulation of the keys 3, the levers 1 of which are connected by links 12 13 to the bell-crank levers 8 and 9, pivoted to posts 10 and 11. The connection between the type-bars and the upper ends of these levers is made simply by inserting the hooked ends of the type-bars into the openings in the levers, and the type-bars are easily detached. This connection is a direct one, no rivets or pins beingnecessaryin either the lever or the type-bar.
I have improved the manner of supporting and guiding the type-bars, my object being to insure perfect freedom and ease of movement of the bars and to secure absolute accuracy in the alinement of the print-ing.
The type-bars at their rear ends rest upon cross-rods, the one marked a supporting the upper series of bars, while the bar a supports the lower series of bars. These crossrods extend between the upwardly-extending posts 31 of the cradle-frame 28, which frame is pivoted at 15 to the stationary framework and is adapted upon the depression of the keys 36 at each side of the bank of keys to shift the upperseries of type-bars out of and the lower series of bars into line with the printing-point to change from upper to lower case printing. The type-bars merely rest loosely upon thesecross-rods a and a and these rods, taken with the bellcrank levers connected to the type-bars at their frontends, constitute the sole support of the said typebars. The rear heads of the type-bars lie in a group between the converging sides 53 of the type-guiding frame, which is carried directly by the cradle-frame instead of independently, as before. In my present con-- struction I depend upon this frame entirely for the proper guiding of the type to the printing-point, and for this purpose the sides 53 of the frame are extended forward far enough to include between them the rear ends or heads of the type-bars, so that Whenever a type-bar is moved it will be guided by this frame toward the printing-point. The shift ing tongue 55 used in my former patents I employ in the present case; but in this instance I mount it loosely upon the cross-bars a a of the cradle-frame. The converging sides 53 53 are sufficiently far apart to permit a loose assembling of the type-bars, so that free lateral play will be allowed and all possibility of the type-bars sticking will be rately into its place.
avoided. The proper lateral guiding of the type-bars is insured by the converging sides 53 53 of the guiding-frame in connection with the shifting tongue, as above indicated, and the guiding in a vertical direction is afforded by the converging upper and lower walls 53 53 of the guiding-frame. .The upper wall 53 is extended forwardly in the form of a cover 53 for the guiding-frame, and this cover confines the type against vertical displacement or jumping out of place, while at the same time allowing sufficient vertical play to insure perfect freedom of movement of the type-bars.
When a key is depressed, the type-bar slides freely and loosely over the crossbar a or a and it can have both lateral and vertical play within certain bounds until the head of the type-bar strikes the converging walls of the guiding-frame and the side of the shifting tongue, when the bar will be directed accu- The converging guiding sides 53 are flared at 53 to provide additional room laterally for the type-bars. The cover 53 is pivoted to the guiding-frame, the pivots passing through ears 53, struck out from the converging guiding-walls, Figs. 1 and 7, and through ears on the cover. The cover is held down in place by its spring-arms 53*, which have indents to engage depressions in the outer sides of the guiding-frame. By this cover access may be had to the type-bars for cleaning, and the type-bars may be lifted up and removed from the machine.
The shifting tongue has elongated openings to receive the cross-rods a 0. while an upper circular opening in the tongue engages the upper rod, this construction affording sufficient looseness for the free working of the shifting tongue.
The guiding-frame has a pivotal action independent of the cradle-frame. Its converging sides 53 are extended forward outside of the posts 31 and are pivoted on the extended ends of the crossrod a, springs 1) serving to hold the frame normally up opposite the printing-point by drawing down upon the hooked forward extensions 1) of the frame. The lower ends of the springs are attached to the cradle-frame, Figs. 2 and 3. By pressing down upon the rear end of this type-bar-guiding frame the printing-point and the last letter printed may be fully exposed, and then by removing the pressure the guiding-frame will rise automatically to normal position. The movement of the guiding-frame is stopped by a projection O thereon engaging an adjustable washer or disk d, Fig. 3. A lug 164:,
Fig. 18, on the opposite side of the frame from that shown in Fig. 3, limits the downward movement of the type-bar-guiding frame. The top plate of the guiding-frame carries the guides cl e'for directing the ribbon from the spools 77 in front of the printing-point.
The depression of the guiding-frame thus serves to lower the ribbon from the printingpoint, and no separate carrier is needed for the ribbon, the pivoted guide-frame answering all the requirements as a ribbon-guide and displaceable support.
The pivot-posts 10 11 of the bell-crank levers are carried by the cross-bar 15 of the cradle-frame, and the arms 35 connect this cross-bar with the keys 3b. The keys 36 are placed under variable tension through the springs 25, the links 26, and the screws 27, Fig. 2, at the front of the machine. The movement of the cradle-frame is limited by disks 50, adj ustably carried by screw-studs depending from the arms 35 of the cradle-frame, said studs passing through openings in the combplate 48, so that the disks can strike upon the upper and lower faces of the said plate. A 1ocking-lever 38, Fig. 2, is used to hold the cradle-frame in position for printing with upper-case type. Thus when the forward end of the lever is thrown up and to the rear the curved end (shown dotted in Fig. 2) will engage the lug 38 on the cradle-frame and tilt the same.
The finger pieces or keys are secured to the upturned ends of the key-levers by the sheetmetal shanks f of the keys, Fig. 17, being bent around the reduced ends of the keylever.
The carriage of the platen is of special construction. As shown in Fig. 14:, it comprises one piece of sheet metal struck up to provide the end frames or brackets 85 and the horizontal connecting-bars 86, leaving an open center g. One edge of the forward bar 86 is turned up for strengthening the frame, as shown at h. The frame also has a number of ears struck up thereon for supporting the parts hereinafter referred to. The platen K, as shown in Figs. 6 and 8, has a plurality of flat faces, and it is supported by the upturned end frames 85. One frame has a notch i to permit the removal of the platen-journal,said journal, in Fig. 13, being engaged by a spring-retaining fork 70, which is screwed in place, as shown in Figs. 1 and 13, the same screw passing through the paper-shelf 96 and into an ear Z, struck up on the carriage-frame. The boss Z is beveled to permit the platen to be removed, Fig. l. The other end ofv the IIO shelf is screwed to a similar car on the other end frame of the carriage. The platen-carriage runs on a roller-frame 151, as in my former construction, and it is guided by the front edge of its front bar 86, fitting under a plate m on the carr iage-bed. The rear bar 86 of the carriage has the escapement rackbar riveted thereto.
I provide two sets of pressure-rollers in the present construction, one set 92, Figs. 2, 4, and 8, being carried by a shaft 01, supported by arms 0, pivoted on a cross-rod p of the carriage-frame, said arms being under tension of the springs 29, connected with links 19 which are adjustable by the screws p carried by the rear bar of the paper-shelf. The other set of rollers 92, Figs. 2, 4, and 11, are carried by small frames q, pivoted on a shaft 91*,
held in ears q, struck out of the paper-shelf, springs (1 being arranged to press the frames,
so that the rollers will be forced against the platen. The frames (1 are of channeled form, and the rollers are journaled in their sides, which are bent up from the main portion.
The paper-scale 94: (designated as such in Fig. 9) is carried adjustably on arms 9 1, pivoted on the cross-rod of the platen-carriage, and the scale is pressed against the platen by the spring 95, held by loops 95, pressed out of the paper-shelf, Figs. 2, 4, and 9. .The paperscale may be adjusted by the slot-andscrew connection, as indicated in Fig. 9.
The paper-clips 91 are supported slidably by engaging the rear bar of the paper-shelf and also by engaging the cross-rod of the platencarriage, for which purpose the clips, which are made of sheet metal, are struck up with cars 92 to engage the cross-rod.
The line-space mechanism is substantially the same as that disclosed in my former patentwith the few exceptions hereinafter noted. The ratchet-wheel is adapted to be engaged by the pawl 100, pivoted to the frame 105, which is journaled on the cross-rod of the platen-carriage, a spring 107 being used to hold the pawl to its work. The frame 105 is operated from the line-space key through the key-lever 1 tat, the link 14%, the lever-arm 145, and the rock-shaft 146, which has leverarm 146 projecting rearwardly therefrom, so as to project under the front bar of the frame 105, so that when the key is depressed the frame is operated to lift the pawl and turn the platen. The shaft 146 is simply arranged by having its journal-pins, Figs. 1 and 10, dropped into open sockets 1', formed on the posts 71, which support the ribbon-spool shafts. The shaft is held from displacement by clips 8 reaching thereover. The line-space regulator 117 is struck up and bent into shape from a single piece of sheet metal. It is journaled on the shaft of the platen and has; a guard-117 arranged when the regulator is, adjusted rearwardly to shield a portion of the ratchet-teeth from the stroke of the pawl 100, so that only a part of the pawls move-j ment will be effective in turning the platen,
but when the finger-piece 117 of the regulator is pressed forwardly the guard 117 will be thrown below the pawl-tooth and said pawl will be active on the teeth throughout its whole movement. The lower end of the regulator is forked to provide stops 102 by is locked by a nut 110". This is convenient for assembling.
In stamping out the platen-carriage an ear 109 is formed for the lever 109, as in Fig. 14. A stop 109 is also formed on the platen-carriage for the lever 109. The detent for the platen consists of a spring-pressed lever 15, carrying a roller i to bear on the ratchetteeth. This lever is carried by a stud 163, held by the nut 163 in the slot 85, Fig. 14, so that the arm 15, which carries the roller i, can be moved backward or forward in order that the flat surfaces of the roller may be brought parallel with the type-face-that is, the roller i bearing on the points of two adjacent teeth determines the position of the platen-roller, and if this roller is positioned to the front or back the flat face of the roller (see Figs. 8, 9, and 11) can be made to assume vertical position.
The escapement mechanism is substantially like that disclosed in my former patent, consisting of the two pawls 131 132 and the wiper 135 with its inclined edge bearing on the pins 133 13-1 of the pawls. The wiper in the present instance is pivoted to an ear cast on the supporting-bed of the carriage, and it is connected with the arm 141 of the rock-shaft 142 by a link 143 instead of being operated by direct contact with the said arm. The rock-shaft is operated through the lever 142 thereon from the bar 1 12, extending under the key-levers. The pawl 132 is normally in engagement with the rack, while the pawl 131 is normally out of engagement, being held so by its pin 133, resting on a high part of the wiper, while the pin 134: of pawl 132 rests on the low part of the wiper. When the wiper is moved to the right, Fig. 4, by the depression of the bar 142, the pin 134 will ride up on the inclined edge of the wiper, lifting the pawl 132, and at the same time the pin 133 will ride down toward the low part, so that it will engage the rack when the same is free from the pawl 132. \Vhen the wiper returns to the left, the pawl 132 falls and the pawl 131 rises. The points of the'pawls are so positioned in relation to each other and the teeth of the rack as to give the step-by-step movement to the carriage.
The tension on the keys is varied by a spring 135 connected to the wiper-arm 138, the other end of the spring being carried by a sliding pawl 1 17, adjustable in a slot in the back plate 126 of the machine, the lower edge of the slot being toothed and the sliding pawl having a tooth 126' to engage the same. The sliding pawl is provided with studs 126 fitting on the inner and outer sides of the back plate to guide it in its movement, and by raising the finger-piece 127 the sliding pawl is lifted out of engagement with the teeth and may be inovedin either direction to increase or decrease the tension on the keys.
As in my former patent, aspecial key (designated as the carriage-release is provided, having a greater dip than the other keys, so
that upon its depression the wiper will be moved to such a position that both pawls will be released from engagement with the rackbar and the carriage will be free to run toward the left until the pawls are allowed to drop into engagement again with the rackbar or until the end of the run is reached. I provide, as in my former case, a yielding support for the pawls, so that when the freelyrunning carriage is arrested the shock will betaken up by said support. This is an arm 131 pivoted at 131 to an ear or boss cast on the under side of the bed-frame of the carriage. A spring 131 holds it normally in position against a stop 160 on the cross-bar 161 of the bed-frame. Thisarm also has a horizontal extension 131 in the path of stops to, carried on the cross-rod of the platen-carriage between the ears of the paper-clips, so that the paper-clips will be prevented from crossing the printing point by the stops striking this extension. The stops also act as the means for arresting the movement of the carriage to the left by striking the extension.
In order 'to lock the key-levers when the end of the line is reached to prevent further printing, I provide an arm 161 on the rockshaft 142, extending rearwardly into proximity to the hooked end of a lever U, which is pivoted to the comb-bar 4. This lever has a weighted end which holds its hooked end out of line with the arm 161, but when the carriage reaches a certain point the finger w on the carriage engages the spring extension X of the locking-lever and moves the hook over the arm 161, so that this arm cannot rise, and consequently the key-levers cannot be operated.
of the arm 161 rubbing against the end of the catch U. Owing to the greater strength of the spring contained in 128, the weaker spring X is caused to deflect,and upon the arm 161' being released the tension of the spring X causes the catch U to snap over the arm 161 and prevents its rising, and consequently stopping the keys from being depressed. The
finger w is pivoted to an ear g, which is struck out of the paper-clip. When, therefore, this paperclip reaches the printing-point, the keys will be locked to prevent further printing. The fingerw also operates the bell-hammer w, Fig. 4, which is pivoted at 102 to the bracket 10 The spring-drum 128 is connected with the carriage by a band 128 which has a loop at its end to engage a hook 128, struck up from the carriage-frame. This loop 128 is secured on the end of the band by a sheet-metal clip 128 Fig. 20, which is of T form, the part a guided to the spring-drum through a bracket or guide 128, which is formed of sheet metal, with a guide-opening at one end, the other end or foot being secured to the cross-bar on the carriage-bed.
The carriage-return mechanism is substantially the same as that formerly used by me, consisting, essentially, of the arms 121 having finger-pieces and connected with a rock-shaft 121, which has a depending arm 120, connected by a link with the bell-crank 119, pivoted under the machine-frame, the long arm of'said bell-crank extending to the rear and being connected through a link 122 with an arm 115, connected with the rack-bar of the carriage.
The means for winding up the spring-drum consists of a disk 124:, having a roughened periphery to be grasped by the thumb and fingers, and a ratchet 125 and pawl 127. The disk fits closely to the back plate, and the arm 115 can move across the rear face thereof.
The type pass through the wire shield 30 when they leave the guiding-frame, and this shield keeps the ribbon off of the platen.
The pivot-posts 10 11 of the bell-crank levers are, as shown in Fig. 19, knurled at their lower ends, thusvproviding a series of longitudinal corrugations, and these posts are simply forced into the cross-bar 15 of the cradleframe. This same method of attachment is employed between the lower end of the spoolshaft 71, Fig. 3, and the miter-gear 141, and it is found that this connection is strong and obviates entirely the necessity of using pins or other fastening means. As shown in Fig. 2, the springs c, which act upon the type-levers, are held by an inverted-U-shaped bar 142 Within this bar another bar 142' is placed, with its open side uppermost, and the right angular extensions of the springs project through these bars. This construction gives an extended bearing to the springs, so that they will be prevented from tilting or turning under pressure.
The key levers at their rear ends are notched, and they engage the comb-bar 4:, a stop-rod X extending under the said rear ends to insure the properposition of the levers.
The ribbon-spools are of special construction. As shown in Figs. 21 and 22, they comprise sheet-metal heads (1, which are struck up with flanges e, and fiat portions f, the latter forming rests or bearings for the sheetmetal back plates 9, which are dished or bent at their edges, and the flanges e are turned over into engagement therewith. In the cavity h of the heads a spring-ring 7c is placed, through which extends the end of the sheetmetal sleeve 71, which connects the heads, said sheet-metal sleeve fitting with its main part within an opening in the metal backing portion and having a shouldered bearing against the spring-ring which determines the relative location of the parts. The sleeve has its reduced ends extending through openings in the sheet-metal heads, and these projecting ends firmly engage said heads, thus securely binding the parts together. The ring serves to space the disks of the spool the proper distance apart and to afiord a shoulder for riveting over the end of the tube or sleeve, by which riveting the sleeve and head are connected. The sleeve itself is formed of sheet metal pressed into cylindrical form, and this provides a split cylinder which will hold to the spool shaft or spindle by its friction, and this frictional hold on the spindle is increased by the spring portion I, struck up out of the sleeve.
The position of the ribbon-spools on the spindles is determined by spring-riug stops m, fitting in grooves in the spindles. This forms a simple stop and may be used at other points on the machine.
The shifting tongue is formed of two thicknesses of metal, which are brought together so that the two lips of these thicknesses are broughtinto contact. I prefer to make these two metal parts of different thicknesses, so that the sound-wave lengths will be different and the vibration of one will neutralize the vibration of the other. This has the effect of deadening the sound by "destroying all ringing effect. As shown in Fig. 7, I may make the two thicknesses of metal forming the tongue by folding the metal back upon itself, one half of the metal piece being thinner than the other. This same principle is carried out in connection with the converging walls and cover of the type-guiding framethat is, the guide-frame is lined with a thin sheet of metal 55, as shown in Fig. 7--and this has the effect of deadening the sound.
As shown in Fig. 23, the clip f, previously mentioned, which holds the key tops to the key-levers, is provided with two spurs or projections f, which are embedded in the glass key top, the said glass being cast into connection with the said spurs. The clip has also a turned-over lip f which prevents the glass from running down into the slot of the clip. The lower split portion of the clip embraces the upturned end of the key-lever, and thus holds the key tops securely thereto. As shown in Fig. 23, I prefer to slot the shank or body part of the clip, which is punched out crosswise of the clip at This is done so as to prevent breaking of the glass by allow ing the metal piece to spring in case of variation of thekey tops.
