20 Claims.
This invention relates to typewriters and other record making machines and more particularly to a power operated carriage return mechanism for such machines.
One object of the present invention is to improve the construction and mode of operation of power operated carriage return mechanisms for record making machines and to produce a novel and improved mechanism by which the carriage of such a machine may be selectively returned by power to any one of two or more returned Positions.
Another object of the invention is to produce, for machines of the above class, a carriage return mechanism for causing the return of the carriage by power to any one of two or more returned positions, having stopping devices for stopping the carriage selectively in the desired position and retaining means for holding the stopping devices in stopping position during the return of the carriage in which novel and improved mechanism is provided for releasing said retaining means to allow the stopping devices to return to normal positions.
With the above and other objects in view, the vention consists in a carriage return mechanism embodying the novel and improved features, constructions and combinations of parts hereinafter described and particularly pointed out in the claims, the advantages of which will be read- 5,
ily understood and appreciated by those skilled in the art.
In the present construction, the retaining means for holding the stopping devices in stopping position, during the carriage return movement, is arranged to be released by various operating mechanisms which may be selectively actuated at the beginning of the next operation of the machine following the return of the carriage. The machine disclosed in this application is provided with mechanisms for releasing the holding or retaining means respectively upon the actu ation of a type key lever, the column tabulator key lever, any one of the decimal tabulator key levers, the release key lever or the space bar. The machine is provided also with mechanism for releasing the stop retaining means upon the actuation of. the line space brake release lever.
The invention will be clearly understood from the accompanying drawings illustrating the invention in its preferred form and the following detailed description of the constructions therein shown.

The invention is illustrated in this application as embodied in a machine having the same general construction, arrangement and mode of operation of parts as the machine disclosed in the patent to Foothorap, No. 1,904,127, dated April 18, 1933.
Except for the mechanisms for releasing the retaining or holding means for holding the stopping devices for stopping the return of the carriage, the various mechanisms of the machine shown in Figs. 1 to 7, inclusive, of the drawings have substantially the same construction, arrangement and mode of operation as the corresponding mechanisms illustrated and described in applicants pending application Serial No. 248,553, filed December 30, 1938, upon which 2 Patent No. 2,286,318, dated June 16, 1942, has been granted.
Referring to the drawings, a fiat platen l is mounted in a platen frame comprising a pair of parallel side bars or rails 2 suitably supported on a standard, not shown. A portion of each bar is toothed to form a rack engageable by traction gears 4 fast on a shaft 6 extending transversely of the side bars and supported by bearings in brackets, one of which is shown at 8, projecting upwardly from the rear side members of the rectangular line space frame Iii. This shaft also carries wheels 9a engaging tracks 8 formed on the side bars 2 and the front rail I2 of the line space frame is likewise supported by wheels, (not shown) engaging said tracks to enable'the line space frame readily to move forwardly and rearwardly along said tracks.
The rear and front cross rails l i and 52- support a key carriage M shown in dot and dash lines in Fig. 1 for travel across theplaten l in letter spacing direction and return, on front and rear Wheels E5.
The key carriage contains the customary key actions, ribbon mechanism and controls for the carriage escapement, not necessary to illustrate, but disclosed in the U. S. patent to Foothorap No, 1,203,519, dated October 31, 1916. The usual spring barrel it is mounted on the line: space frame' re, a tape 3 connecting the spring barrel with the key carriage M to draw the carriage toward the right in letter spacing direction under control of the escapement mechanism.
Power drive The key carriage Hi may be manually returned to the left hand margin from any point to which it has been advanced in letter spacing direction, but to relieve the operator of the work of return ing the carriage, a motor 2a is provided, conveniently mounted on a casting, (not shown) secured to and projecting rearwardiy from the rear rail l l of the line space frame lfi-with which it travels.
Referring to Figure 2 of the drawings, power from the motor is taken from the worm 22 fast on the motor shaft 243 and meshing with a worm gear 25 having a friction clutch connection 28 with a counter shaft 39 journaled in the casting and extending forwardly beneath a carriage -return rack 3! secured to the flanged rear end of an apron 32 projecting from the deck at of thekey carriage It.
A wide carriage return pinion 38 journaled on the forward end of the counter shaft 36 and axially movable along the shaft, meshes with the teeth of the carriage return rack 3i at all times, the return pinion having a peripherally grooved collar terminating at its rear end in a driven clutch member 4i! normally disengaged from a driving clutch member 62 fast on the counter shaft.
The free end of a clutch shift finger it lies in the groove in the sliding rotatable collar 33, the finger being secured to a clutch shifting shaft it journaled in the motor support casting A clutch shifting arm to fast on one end of the clutch shifting shaft to is provided with a lateral looking lip i} normally engaged by a locking latch 52 j'ournaled on a trip shaft 5 extending across the machine and supported in bearings projecting from the back of the rear rail I l of the line space frame. A fan-shaped trip arm 56 secured to the trip shaft 5% extends rearwardly between two studs'fis and 6t projecting respectively from the hooked latch 52 and from the clutch shifting arm at, a normally tensioned spring 62 connecting the two studs to form a yielding link therebetween and normally maintaining the hooked latch 52 engaged with the clutch shifting arm 48 to retain the clutch members so and 42 disengaged.
Control of automatic carriage return mechanism Curved arms projecting upwardly and forwardly from the trip shaft support a tripping bail M toothed at its opposite ends and rocking with the shaft it. Mounted on the right hand end of the tripping bail is a cam block 6% arranged to be engaged by a roll 95 projecting downwardly from the carriage apron.
In the normal positions of the parts, the hooked latch 52 is engaged with the lip 59 of the clutch shifting arm t8, and the trip shaft 54 is retained in its limiting counterclockwise position, Fig. 2, and the tripping bail M is retained in its rearmost position by the action of the spring 62. As the carriage l4, travelling in letter spacing direction, advances the printing point toward the extreme right hand margin of the work sheet, the roll 95 wipes across the inclined face of the camblock titand rocks the bail forwardly, thereby rocking the trip shaftfid in aclockwise direction, Fig. 2.
The rearwardly projecting trip arm 55 is swun upwardly by the rocking movement of the trip shaft to disengage the hooked latch 52 from the clutch shifting arm '38 and, in so doing, additionally tensions the spring 62, which spring, acting as a tension link, rocks the clutch shifting shaft t8 and its clutch shifting finger'- l counterclockwise, Fig. 2, to slide the driven member "if! of the carriage return clutch along the counter shaft 36 into engagement with the driving member the carriage return pinion 36 being of sufficient width to maintain'its engagement with the carriage return rack throughout the clutch shifting action.
The motor 29 is preferably of the constantly running type and will then drive the carriage in contra-letter spacing direction toward the left hand side of the machine. As the carriage approaches the end of its'return movement under the influence of the motor 2B, the tripping bail St is swung back rearwardly to its normal position. During this operation, the'tripping arm 56 is pressed against the stud 60 on the clutch'shifting arm #38 and rocks the arm, together with the clutch shifting shaft iii and clutch finger 4 3 in a clockwise direction, Fig, 2, to cause the finger to disengage the driven clutch member to from the driving clutch member 42 thereby disconnectinga the motor 2t from the travelling carriage l The'spring G2 tends to'draw'the hooked latch 52 downwardly, as the clutch shifting arm 55 is swung downwardly and when the arm it reaches a certain position, the latch snaps down over the lip at on said arm to lock the-clutch shift'mechanism, and hence the clutch-members, in disengaged positions.
All of the mechanisms above described, have substantially the same construction arrangement and mode of"operation as the corresponding mechanisms of the machine'illustrated and described in applicants pending application Serial No. 149,571, filed June '22, 1937, except that a continuously running motor is employed in the present machine and the switch and control mechanism for closing the motor circuit upon throwing in the carriage return mechanism and for opening the motor circuit upon throwing out the carriage return mechanism are omitted.
The mechanism for swinging the tripping bail 64 rearwardly as the carriage approaches the end of its return movement will be hereinafter described.
Partial carriaoe return The present machine is provided not only with mechanism for automatically returning the carriage to position to begin the typing of a line, but is also provided with mechanism for stopping the carriage in fully returned position or in either of two partial return positions at different distances to the right of its fully returned position. In carrying out the invention, three carriage return keys are mounted on the key carriage I4 in place of the single carriage return key shown and described in Foothorap Patent No. 1,904,127. By the respective actuation of these keys the carriage return mechanism will be thrown into operation and the return movement of the carriage will be caused to be arrested with the carriage in any one of three different return positions, the stop position being selected by the actuation of the appropriate key.
Referring to Figs, 1, 2 and 7 of the drawings, the keys controlling the return under power of the carriage from any advanced position to a selected precedent position are mounted on the travelling carriage I4 and arranged in a novel manner to enable the selection of any of several precedent positions to which the carriage may be returned. The machine is provided with a key lever I22, the actuation of which causes the engagement of the carriage return clutch to effect the return movement of the carriage. The key lever 122 which extends along the left side wall of the carriage is pivoted at I24 to the rear portion of the carriage frame, and is acted upon by a coiled spring I23 which normally maintains the same in elevated position. This key lever extends forwardly to a point adjacent the keyboard of the key carriage and terminates in an upwardly projecting stem extending through a slot in a guide plate I25 secured to the inclined keyboard frame, the stem having a transverse stop pin I28 to limit the extent of depression of the key lever, A key I36 is fixed to the upper end of said stem and the depression of this key causes the return of the carriage to its limiting left hand position.
A bell crank lever I32 pivoted at I24 concentrically with the key lever I22, depends from this pivot pin, the depending arm constituting a support for an extension I34 adjustably secured, as by a pin and slot connection I36 and a pivot I38 spaced therefrom, to the depending arm of the bell crank. This extension is slotted as at I45 to embrace a stud I42 on a radial arm I44 secured to a horizontal rock shaft 146 journaled in bearings on the key carriage frame. This shaft extends part way toward the right hand side of the key carriage and at its inner end carries an arm I48 depending through a slot in the apron 32 to a point in proximity to and be hind the trip bail 64.
The remaining shorter arm of the bell crank 132 projects forwardly substantialy parallel with and below the key lever I22 and the free end of said arm is provided with a lip I50 formed thereon to contact normally a rigid headed pin I52 projecting from the left side of the key carriage I4 which arrests the parts at one extreme of their movement.
A restoring spring I54 (Fig. 1), encircling the shaft I46, yieldingly retains the arm I48 withdrawn from the trip bail 64, the headed pin I52 serving to limit the clockwise rotation of these parts under the influence of the spring I54 and to confine the parts against lateral displacement.
A by-pass pawl I56 pivoted at I58 intermediate between the ends of and depending from the key lever I22, is turned clockwise by a spring I60 until its free reduced end is arrested by contact with the fixed pin I52, in such position as to lie in line with the lip I 56 on the short arm of the bell crank I32, The key lever I 22, when depressed, forces the reduced end of the by-pass pawl I56 against the lip I55 of the short arm of the bell crank I32, and rocks the bell crank clockwise (Figs. 1, 2 and '7). This movement of the bell crank, through arm I44 and shaft I48 rocks the arm I48 counter-clockwise against the trip bail 64 to actuate said bail to close the carriage return clutch 4U, 42 so that the carriage is returned toward the beginning of a line.
The depression of the key lever I22 to its fullest extent brings the sharply inclined edge I62 of the by-pass pawl into wiping contact with the limit pin I52 which operates to cam the by pass pawl off from the lip I55. When this occurs the spring I54 restores the arm I48, shaft I55, arm I 44, and bell crank I32 to their normal positions irrespective of and uncontrolled by the key lever 122. This enables the key lever I22 to be operated by respectively different strokes to effect the complete and the partial return movement of the carriage as will hereinafter appear.
To enable the carriage to be arrested in difguide plate I25 above the stem of the key lever I22 and having a key I65 fixed to the upper end of said stem and with a third key lever I68 having a stem projecting upwardly through said guide plate above and to the rear of the stem of the lever I6# and having a key I10 fixed to the upper end of said stem. The key lever I68 extends downwardly and rearwardly across the left hand end of the k y carriage I4 and its lower I74 depending a predetermined distance below the left hand lower corner of the key carriage I4. The inner face of the guide plate I72 is vertilever I68. The lever I68 is acted upon by a coiled return spring I18 which normally holds the lever yieldingly in its uppermost position.
The lever I64 is pivoted at I86 on the lever I68 and, upon being depressed, is arranged to actuate the lever I58through an eccentric I82 fixed to, and rotatably adjustable on, the lever I64 and engaging in a slot I83 in the lever I68. This slot provides lost motion between the lever I64 and the lever I68, the amount of which may be regulated by adjusting the eccentric I82.
In order that the lever I22'may be depressed I64 or the key lever I68, the lever I22 carries a pin I84 secured in an upwardly projecting portion of the lever and engaged by the lever I64 during the downward movement of the latter ledownward movement ver. This pin engages in a slot lSli in the lever I64 and forms a guide for said lever but permits the lever I22 to be depressed freely independently of the lever ltd.
The pin l28 constitutes a stop limiting the of the levers I54 and I68 as well as the lever I22. The upward movement of the lever ltd is limited by the engagement of a stop face ltt formed on said lever with the under side of the guide plate ltt. This limits also the upward movements of the lever i222 and of the lever M38.
The mechanism cooperating with the check stop we to arrest the return movement of the carriage has the same construction, arrangement and mode of operation as the corresponding mechanism illustrated and described in applicants application Serial No. 149,571. Said mechanism comprises a draft rod lei! extending transversely of the line space frame. This rod is T- shaped in cross section and is arranged to slide in a channel formed by the rear rail ll of the line space frame, the web I92 projecting forwardly therefrom and the carriage escapement rack lllZ which is secured to the forward edge of said web.
The left hand end portion of the draft rod lad is toothed for a considerable distance and arresters We, I96 and le of different heights are adjustably arranged on the draft rod to be engaged respectively by the fixed abutment are and the check stop lit to arrest the carriage during its return movement at any one of three precedent positions and also to effect a line spacing operation incident to its return to any such precedent position. The arrester ltd of least height is located farthest to the right and the arresters led and lllli of successively greater heights are mounted on the draft rod in corresponding order to the left of the arrester I94. These arrest-ere preferably have substantially the same construction as illustrated and described in applicants application Serial No, 149,571, to enable them to be readily adjusted longitudinally on the draft rod.
The left hand end of the draft rod ltd passes through an aperture in a rearwardly turned slotted projection 250 on the left hand end of a slide 2% extending therefrom toward the right along the front face of the carriage escapement rack M2 to which the slide is connected by headed fastenings 2M engaging in slots 2% in the slide. The slide operates to guide the draft rod in its endwise travel and prevents it from canting in its channel.
The draft rod is provided at its right hand end with a threaded portion 2&8 passing through a block 2H3 secured to the forward face of an arresting plate 2l2, thedraft rod being secured to said block by means of nuts 2M threaded on the rod and located upon opposite sides of the block. The arresting plate fit; is provided with parallel slots fit and Elli through which pass respectively a headed fastening 228 and a stub shaft 22?; to support and guide the plate.
The arresting plate 2 l2 is formed with a beak 224 which projects toward the left from the upper left hand edge of the plate into position to collide with a forwardly extending fixed stop 22%) (Fig. 1) rigidly secured to the right hand end of the rear rail ll.
A coiled spring 223 secured at one end to the fixed stop and connected at its opposite end to the draft rod lei yieldingly retains the arresting plate M2, the draft rod and the slide 2B2 at their V the fixed abutment'll l passes over right hand limits of travel as determined by contact of the left end wall of the slot 216 in the arresting plate with its guiding and supporting stud or headed fastening 220.
When the operator, at any point Vance of the carriage, riage to its limiting left hand position or to give a full return movement to the carriage, he depresses the key ltll and key lever l22 to their limiting positions determined by the engagement of the stop pin l28 with the guide plate I26. During the downward movement of the lever, the bell crank l32 is actuated to engage the carriage return clutch after which the pawl lat is cammed off the lip lei) of the bell crank lever so that the key lever exercises no further control on the bell crank and the parts operated thereby. After actuation by the key lever, the parts of the clutch engaging mechanism between the arm M8 and the clutch are maintained in position until the carriage approaches the end of its return movement. The check stop l'lli is not depressed by this operation but remains in its uppermost position.
During the return movement of the carriage, the graduated arresters led and l9 5 and finally engages the highest arrester 593, the location of which on the draft rod determines the beginning of a line of writing.
The abutment ll l, upon contact with the abrupt right hand face of the arrester E98, forces the arrester to the left and with it the draft rod led and arresting plate M2, tensioning the return in the adspring 228, until the beak 221i impinges against the fixed stop 226 which positively arrests further travel of'the draft rod and the arrester use leftwardly and hence arrests the carriage M in its predetermined extreme leftward position to define the left hand margin and the beginning of the writing line.
A slight play is arranged between the right hand end of the draft rod and the block ill! to enable the escapement to lock the carriage at a uniform point upon each return of the carriage.
As the draft rod is moved to the left by the final movement of the carriage, the carriage return clutch is disengaged by mechanism hereinafter described.
When the operator desires to arrest the return movement of the carriage in a position to the right of the full return position as determined by the arrester I38, he depresses the key lliil and the key lever ltd. The depression of the key :1SVI I5 5 depresses the lever l22 through the engagement of the lever I6 3 with the pin ltd to throw the carriage return mechanism into operation, the movement of the lever l22 and the lever ltd being limited by the engagement of thepin lEE with the guide plate i126. During the downward movement of the lever Hi l, the eccentric 582 engages the lower side of the slot in the lever l68 and said lever is moved downwardly to project the stop l'iG downwardly to a position such that it will clear the arrester I94 but will engage the arrester I96 during the return movement of the carriage. During the return movement of the carriage, the check stop H6 passes over the arrester ltd and engages the arrester lift as the carriage approaches the end of its return movement and slides the draft rod to the left in the same manner as before until the movement of the carriage is finally stopped by the engagement of the beak 224 on the slide 2-l2 with the fixed stop 22%.
desires to return the car- 242 to hold the lever When the operator desires to arrest the return movement of the carriage in a position to the right of the partial return position determined by the engagement of the check stop with the arrester I96, he depresses the key I10, and key lever I68. The depression of this key lever I68 depresses the lever I64 through the engagement of the eccentric I82 with the upper side of the slot I83 in the lever I68 and the depression of the lever I64 depresses the lever I22 through the engagement of said lever I64 with pin I84, the movement of the levers being limited by the engagement of the pin I28 with the guide plate I26. The depression of the lever I22 throws into operation the carriage return mechanism as before. The downward movement of the lever I68 projects the stop I16 to a lower position than that into which it is projected by the depression of the lever I64 to cause the stop to engage the arrester I94 during the return movement of the carriage. As the carriage executes its return movement under the action of the power mechanism, the check stop I16 engages the arrester I94 thereby moving said arrester and the draft rod ISO to the left until the movement of the carriage is stopped by the engagement of the beak 224 with the stop 226;
It is highly desirable that the mechanism for stopping the return movement of the carriage in the two partial return positions should be maintained operative after a quick depression and release of either of the keys I66 and I10. Otherwise, it would be necessary for the operator to maintain each of these keys in depressed position during the return of the carriage in order to stop the carriage in the desired partial return position. In order to secure this result, mechanism is provided for holding the check stop I16 in either of the positions into which it is projected by these keys respectively after the quick depression and release of the key.
The mechanism for holding the check stop in position comprises a latch bar 230 pivoted upon a stud 232 secured in a projection on the lever I68 and depending therefrom in the manner clearly shown in Figs. 5, 6 and 7. The latch bar is loosely pivoted on the stud 232 so that not only can the stud turn freely within the latch bar, but the latch bar can swing freely in a vertical plane containing the axis of the stud. The latch bar extends downwardly from the lever I68 through an opening 234 in a guide plate 236 formed on a bracket 238 secured to the side of the deck 34 of the key carriage. The latch bar is formed with notches 246 and 242 arranged to receive alternatively a catch 244 formed by the beveled edge of the guide plate 236 to hold the latch in either of two depressed positions. The latch bar is acted upon by a leaf spring 246 secured to the stud 232 and bearing against thelatch bar which normally mainouter face of the check stop I16 to engage the arrester I84 during the return movement of the carriage.
The latch bar is arranged to hold the lever I 68 and the stop I16 carried by said lever in the position into which they are moved by the depression of a key during the return of the carriage. Thereafter the latch bar is actuated to release the catch 244 from the notch in the latch bar in which it is engaged by any one of a number of normal machine operations and the lever I 68 is then moved upwardly to its upper limiting position by the return spring I18.
The latch bar is swung outwardly to disengage the catch 244 from the notch in the latch bar by the depression of a type key lever.
In the present construction a ribbon vibrator mechanism is employed having substantially the same construction, arrangement and mode of operation as the corresponding mechanism illustrated and described in the patent to Foothorap No. 1,286,573, dated December 3, 1918. This mechanism comprises a vibrator lever 248 pivoted on a stud 259 secured in a bracket 252 attached to the deck 34 of the machine head. This vibrator lever is formed with an upwardly extending arm having an arcuate slot 266 in which engages a pin 253 fixed in the forward end of a link 266, the rear end of which is pivoted at 262 to the downwardly extending arm 264 attached to the universal bar rocker 266. The pin 253 also engages in a slot 268 in a vertically adjustable shifter 216 mounted to slide vertically upon a bracket 212 attached to the framework of the machine head. The universal b'ar rocker is provided with forwardly extending arms 214 from which are suspended the hangers 216 which carry the universal bar 218. This bar underlies an abutment screw 28!: mounted on each of the type key levers one of which is shown in Fig. 4 and is indicated at 282. Each of these levers is pivoted on the transverse shaft 284 and is provided, at its forward end, with a key 286 by which the lever is depressed and with a return spring 281 by which the lever is restored to normal position. The arm 254 is acted upon by a return spring 289 and the lever 248 is acted upon by a return spring 291 which springs tend to restore the rockor 256 and the lever 243 to normal positions after each depression of the universal bar. Upon the depression of the type key lever, the universal bar is depressed therewith and through the connections described, the ribbon vibrator lever 248 is swung in a counter-clockwise direction, Figs. 2 and 4, this movement advancing the lower arm of the lever.
The lower arm of the ribbon vibrator lever carries a cam plate 288 fixed thereto and having an inclined cam face tains the latch bar in engagement with the edge of the catch 244.
When the key I66 and key lever I64 are depressed to their limiting positions, the latch bar is depressed to a engages in the lower point at which the catch 244 notch 240 to hold the lever I68 in position to locate the check stop I16 to engage the arrester I96 during the return movement of the carriage. When the key I10 and lover I63 are depressed cause the catch 244 to engage in the upper notch to their limiting positions, the latch bar is depressed into position to 290 (see Fig, 1) for engaging the inner side of the latch bar 230. When the carriage return key levers I64 and I68 are in their uppermost positions, the lower end of the latch bar 230 lies above the cam plate 288 so that the cam plate does not engage the same during the movements of the vibrator lever. When either of said carriage return key levers is depressed, the latch bar 230 is moved downwardly to carry the lower end thereof below the cam plate 288 which then occupies a position to the rear of the 7 latch bar and the lat-ch bar is retained in this I 0? position by the engagement of the catch 244 in one of the notches 240, 242. Then upon the depression of a type key lever, the forward move ment of the lower arm of the-lever 243 carries e cam plate 288 into engagement with the latch th I68 in position to locate the 751 bar and the latch bar is swung to the left (Figs.
5 and 6) to release the same from the catch. The key lever I38 and the. stop WE are then restored to their uppermost-positions by the action of the spring H8.
Upon the release of the type key lever, the universal bar is lifted to its normal position and the ribbon vibrator lever 248 is swung back in a clockwise direction to its initial position by the action of the return springs 283 and 23!.
The machine is provided with a decimal tabulator mechanism having substantially the same construction arrangement and mode of operation of parts as the corresponding mechanism illustrated and described in the patent to Foothorap No. 1,280,697, dated October 8, 1918. The present machine isprovided with mechanism which, upon the depression of any one of the decimal tabulator keys in the next operation following the return of the carriage to a partial return position, will swing the latch bar 239 outwardly to disengage the same from-the catch 244 and thereby release the lever I33 and the check stop I33,
The decimal tabulator stop mechanism comprises the usual series of decimal tabulator key levers one of which is shown in Fig, 2 and is indicated at 293. Each of these levers is pivoted at its rear end to a bearing member depending fromthe cover plate 298 and is yieldingly held in its uppermost position by a retracting or return spring 333. Each of the decimal tabulator key levers is arranged to engage the upper side of the bail 332'pivoted at 3634 upon bearings suspended from the cover plate and extending transversely beneath the several levers, the bail being normally held in elevated'position by a spring 335. To the bail is secureda forwardly extending arm 3i6-carrying at its forward end a'pin 338 ongaging in a slot 3H] in a cam lever 3l2 pivoted at 314 upon the side plate of the machine head. To the lower end of the lever H2 is attached a cam plate 3l3 arranged to extend behind the latch bar 233 as clearly shown in Fig. 3.
When the parts are in their normal positions, the angular location of the lever M2 is such that the cam 313 occupies its rearward position so that 1 it does not engage the latch bar 230. With the above construction, upon the depression of any one of the decimal tabulator keys the bail 332 is swung downwardly and through the connection between-said bail and the lever 312, said lever is swung in a counter-clockwise direction (Fig. 2). If the lever I63 and the check stop Hi5 are then held in depressed position by the engagement of the catch 244 with one of the notches 240, 242 in the latch bar, the movement of the lever EH2 will engage the cam 313 with the inner side of the latch bar 233 and said bar will then be swung outwardly to disengage the same from the catch and thereby release the lever W8 and said check stop.
The present machine is also provided with a column tabulator mechanism having substantially the'same construction, arrangement and mode of operation of the parts as the corresponding mechanism illustrated and described in said Footho-rap Patent No. 1,280,697. This mechanism comprises a column tabulator key lever 3l8 pivoted'at33il on the frame of the machine. This lever isarranged to throw out the holding dog of the usual escapement mechanism and to interpose a stop on the carriage in the path of a fixed stop mounted on the tabulator bar to stop the carriage ina predetermined columnar position. The mechanism for throwing out the escapement dog and for actuating the stop mechanism to interpose the stop on the carriage in the path ofthe fixed stop on the tabulator bar preferably has substantially the same. construction and mode of operation as the corresponding mechanism illustrated and described in said patent and is, therefore, not disclosed herein.
- The mechanism for releasing the latch bar 233 from the catch 244 upon the depression of the column tabulator key lever comprises a rocker bail indicated generally at 322 and having a body 324 which is inserted in a U-shapedportion 326 of the casing of the machine head in front of the keyboard and is held therein by screws 338. The right hand end (Fig. 3) of'the rocker bail, is provided with a rearwardly extending arm 333 having a lateral extension 332 which projects beneath the column tabulator key lever figure. The bail 322 is provided at its left hand end (Fig. 3) with a rearwardly extendingarm 334 having a lateral extension 336 located above the forwardly extending arm of a latch throwout lever 338 pivoted at 340 on the side plate of the carriage. The downwardly and rearwardly extending arm of this lever is formed with a cam 342 arranged to engage the inner side of the latch bar 233. The latch throwout lever 33B is acted upon by a coiled spring 344 which tends to swing the same in a counter-clockwise direction (Figs. 2 and '7) and to carry the cam 342 out of position to engage the latch bar 23!).
The throwout lever 338 is connected by a coiled spring 345 with a projection on the lever I38, this spring acting in opposition to the spring 344. When the lever I53 is in elevated position, the spring-345 is distended so that its tension is sufficient to overcome the tension of the spring 344 and the lever 338 will therefore be maintained in the position shown in Fig. 2, the movement of the lever under the tension of the spring 345 being limited by the. engagementof a projection 34'! on the lever with the bracket 238. When the lever I68 is depressed, the tension exerted by the spring 345 is diminished sothat it will be overcome by that of the spring 344 and. the lever 338 will be maintained substantially in theposition shown in Fig, 7.
With the parts in their normal positions as shown in Fig. 2, in which the lever I63 is in elevated position, the lever 338 is held by the spring 345 in the position shown in this figure with the cam 342 in engagement with the latch bar 233. It will be noted that with the lever 338 in this position, the forwardly extending arm of said lever lies slightly below the extension 336 on the bail 322 and said bail is held by gravity in depressed position with said extension resting on a contact surface'on the frame. Upon the depression of the carriage return key lever I68, the lever 333 is swung by the spring 344 in a counterclockwise direction into the position shown in Fig. '7, thereby disengaging the cam 342 from the latch bar 23!] to allow said bar to swing inwardly to engage the catch 244 in one of the notches 243, 242 and the forwardly extending arm of the lever 338 engages the extension 336on the bail thereby swinging the bail upwardly into operating position as shown in said figure.
Because of the fact that when the lever N38 is in its normal elevated position, the bail 322 is allowed to assume its depressed position by the position of the lever 338, the bail is not then engaged by the column tabulator lever 3H3 or any of the levers by which it is actuated to release the latch bar 233.
With the parts in the positions shown in Figs.
MS as shown in said and '7 in which the lever I68 is in depressed position and the catch is engaged in one of the notches of the latch bar to hold the lever I68 and stop I16 in depressed position, upon the depression of the column tabulator key, the bail 322 is actuated by the engagement of the column tabu lator key-lever with the extension 332 to swing the extension 336 downwardly, the bail being swung from the position shown in Fig. 7 to the position shown in Fig. 2. During this movement of the ball, by the engagement of the extension 336 with the forwardly extending arm of the lever 338, said lever is swung in a clockwise direction thereby moving the cam 342 rearwardly. The engagement of the cam 342 with the latch bar swings said bar outwardly to disengage the same from the catch thereby releasing said lever I68 and stop I76 and allowing them to be moved upwardly to their normal positions.
The present machine isprovided with a release key lever 346 and with mechanism operated by the depression of said lever for holding out the holding dog of the escapement mechanism to allow free movement of the type carriage while the lever is depressed. The connections between the release key lever and the escapement mechanism for releasing the holding dog have substantially the same construction, arrangement and mode of operation as the corresponding mechanism illustrated and described in the patent to Foothorap No. 1,203,519, and are therefore not disclosed herein.
The release key lever is pivoted on the shaft 264 and its forward end extends over the lateral extension 332 on the bail 322 as shown in Fig. 3, the release key lever being located some distance above the column tabulating key lever as shown in Fig. 4. A link 338 is pivotally suspended at 350 upon the release key lever and is formed at its lower end with a slot 352 in which engages the lateral extension 332 .on the bail 322.
With the lever I 68 and stop I16 held in depressed position by the engagement of the catch 244 in one of the notches of the latch bar, upon the depression 348 engages the lateral extension 332 on the bail when said extension reaches the upper end of the slot 352 and the bail is thereby swung in a direction to depress extension 336 at the opposite end thereof. This movement of the bail swings the latch bar throwout lever 338 in a clockwise direction from the position shown in Fig. 7 in substantially the same manner as by the depression of the column tabulator key lever above described, and the latch bar will be actuated to release the same from the catch and allow the lever I63 and the stop I76 to be moved back upwardly to normal position.
The present machine is provided with a space bar 354 fixed to forwardly extending arms on a space bar yoke 356 pivoted on the shaft 353 extending across the machine and connections are provided between the space bar yoke and the escapement mechanism for controlling the escapement. These connections preferably have substantially the same construction, arrangement and mode of operation as the corresponding mechanism illustrated and described in said patent to Foothorap No. 1,203,519 and are not disclosed herein.
Mechanism is provided for releasing the latch bar 238 from the catch 244 upon the depression of the space bar. This mechanism comprises an arm 358 secured to the body 3240f the bail 322 and extending beneath the forward end of one of the release key lever, the link of the arms on the yoke 356 adjacent the space bar as shown in Fig. 3 and arranged to be engaged by said arm.
With the lever H63 stop I held in depressed position by the engagement of the catch 24 5 in one of the notches in the latch bar, upon the depression of the space bar, the arm 366 on the bail 322 is engaged by the adjacent arm of the yoke 356 and the bail is swung in a direction to depress the lateral extension 335. This movement of the bail actuates the latch bar throwout lever 333 in substantially the same manner as by the depression of the column tabulator key described above, to release the latch bar from engagement with the latch and allow said lever I68 and stop It; to move upwardly to their normal positions.
The machine is provided with the usual line space brake release lever indicated at 33I pivoted on the shaft 353. The forward end of this lever is provided with a laterally bent portion 333 which extends over the forwardly extending arm of the lever 338. With the lever I68 and the check stop I13 held in depressed position by the engagement of the catch 234 in one of the notches in the latch bar, upon the depression of the forward end of the lever 3%, the lever 338 will be engaged by the lever 36! and swung in a counter-clockwise direction (Fig. '7) to release the latch bar from said catch and allow the lever 38 and said step to move upwardly to their normal positions.
The disconnection of the motor from the carriage is automatically effected regardless of the extent of return travel of the carriage by a mechanism adapted to function just prior to the arrest of the carriage at any of its completely or partially returned stations. The said mechanism comprises a floating thrust bar 365 slidabiy supported adjacent its left hand end in an eye 36! formed in a bracket secured to and projecting from the adjacent vertical bracket 8 on the line space frame. The thrust bar is slotted at its right hand end as at 363 to ride on the rear end of a stud 3' pro-- jecting rearwardly from and travelling with the arresting plate H2. The left hand end of the thrust bar is arranged to engage an inclined cam face on a member 373 secured to the right hand end of the trip bail 64 in the path of travel of the thrust bar.
The length of the slot 333 in the thrust bar is less than the distance normally between the beak 223 and the fixed stop 226. Therefore, as the arresting plate 2I2 is drawn to the left by contact of the abutment I M with the arrester I98 or by contact of the check stop I16 with either of the arresters 594 or I35, the supporting stud 3 will travel idly along the slot 369 of the thrust bar until just prior to the arrest of the plate 252 by contact of the beak 224 with the stop 326, the supporting stud 3?! reaches the left end wall of the slot 339. Thereafter, the continued movement of the arresting plate 2I2 shifts the thrust rod to the left against the inclined face of the contact member trip bail and rocks the trip bail back to its normal position, thereby disconnecting the shiftable driven clutch member of the carriage return clutch from the driving clutch member.
In the construction shown in Figs. 8, 9 and 10, the machine is provided with three carriage return keys for throwing the carriage return drive mechanism into operation and for projecting the partial carriage return stop into selected 3'23 on thein the slot 38b in the latch bar.
operative position when the carriage is to be stopped in either of two partial carriage return positions. The key lever i221; which is pivoted at H511 and carries the key I3Ba, the key lever IG i-a which is pivoted at ifiiia on the key lever 58a and carries the key Nita, and the key lever liiilo which carries the key mm, except as hereinafter described, all have substantially the same construction, arrangement and mode of operation as the corresponding mechanism shown in Figs. 1 to '7 inclusive.
The lever 522a operates the lever lti'a to throw in the carriage return mechanism by the engagement of the pawl i561], pivoted at l58a on the lever l22a with the arm The connections between the lever i32a and the carriage return clutch have substantially the same construction, arrangement and mode of operation as the connections between the lever I32 and the clutch shown in Figs. 1 to 7, inclusive.
The key lever i220, carries a pin i280, which engages the cover plate [26a to limit the downward movement of the lever I22a. The lever I22a is provided with a slightly yielding projection 362 which is engaged by a projection 354 on the key lever lfifia so that the lever E2200 is depressed by the depression of the lever lii la. The lever [6 1 a carries an eccentrically mounted stud H8200 engaging in a slot I83a in the lever loea to provide a lost motion connection between the two levers, the lever lfita being depressed with the lever lead through the engagement of the stud [82a with the lower side of the slot. The lever 168a is guided in its Vertical movements by the engagement of the stop l'liia behind the guide plate llZa and by a headed stud 355 secured to the cover plate HM and engaging in a slot 358 in the upper portion of the lever 868a.
The mechanism for holding the lever 58a and the check stop l'lta in either of the positions into which they are projected by the depression of either of the keys H80 and Mafia. in the construction shown in Figs. 8, 9, and 10, comprises a longitudinally movable latch bar 310 pivotally supported at its lower end t 3'52 upon the vertical extending arm of a bell crank lever 3M pivoted at 3'16 on the side plate of the type carriage. The latch bar 316 is slidably supported adjacent its upper end by means of a stud 313 secured in the side plate and engaging The latch bar carries a latch plate 382 having a beveled edge arranged to engage alternatively in the notches 384 and 385 formed in the upper part of the key lever I63. The latch bar is acted upon by a coiled spring 383 which tends yieldingly to move the same forwardly or to the right, (Fig. 8) thereby maintaining the latch plate 382 in engagement with the left hand opposed edge of the key lever lt a.
Fig. 8 shows the parts in their normal positions with the latch plate 2582 held in engagement with the adjacent portion of the lever [630. by the action of the coiled spring 388.
Upon the depression of the lever lt'a'fia by the depression Of key llfila, the lever lt ia. and the lever iZZa are carried downwardly therewith and the movement of said levers is limited by the engagement of the stop pin l2iia with the cover plate l26a. t the end of this movement of the lever liilia, the latch plate 362 is engaged in the notch 385 in said lever to hold the lever and the check stop llfia in position. This depression of the lever Nita depresses lfiiia of the lever liiza.
the stop l'liia into position to engage the arrester I94 to arrest the carriage in one partial return position. Upon the depression of the key lever lii ia by the depression of key ifiiia, the levers ifiiia and lEZa are carried downwardly therewith and the movement of said levers is again limited by the engagement of the stop pin 'lfiiia with the cover plate l26a. The downward movement of the lever i580, produced by the depression of the lever lt la carries the lever 58a downwardly into position to engage the latch plate 382 in the notch 35!- in said lever. This depression of the lever ltfila will depress the check stop I'liia into position to engage the arrester 556 to arrest the return movement of the carriage with the carriage in another partial return position. The engagement of the latch plate 382 in either of the notches 38 i, 386 on the lever i580, will hold said lever and the check stop in position during the return of the carriage.
In order to disengage the latch plate 382 from either of the notches 38d and and thereby release the lever Nita, the latch bar 379 is moved rearwardly or to the left (Fig. 8) against the tension of spring 388. As shown clearly in this figure, the horizontally extending arm of the bell crank 31 i is arranged to be engaged by the lateral extension 33% on the bail 322a.
This bail has the same construction and arrangement as the bail 322 shown in Figs. 1 to 7 inclusive, and is operated in the same manner by the release key lever, the column tabulator key lever and the space bar. When the lever I660; is in elevated position and the latch bar filil is held in its rearward position by the engagement of the latch plate 332 with the opposed face of the lever lfiiia, the bell crank lever 314 is located in the position shown in Fig. 8 with its horizontally extending arm lowered. The bail 322a is then located in lowered position as shown in said figure so that it is not actuated by the release key lever, the tabulator key lever or the space bar. Upon the depression of the lever Kidd and the shifting of the latch bar 3'13 forwardly to engage the latch plate 382 in one of the notches 38 i, 386, the bell crank lever 31 3 is swung into the position shown in Fig. it. By this movement of the bell crank lever, the bail 322a is swung upwardly into operating position as shown in said figure. With the bail in this position, upon the depression of the bail produced by the depression of the release key, the column tabulator key or the space bar, the bell crank lever 3Y4 is swung in a clockwise direction (Figs. 8 and 10) by the engagement of the extension 336a on the bail therewith and the latch bar 3% is moved rearwardly to release the lever 58a and allow the same and check stop Mild to move upwardly to their normal positions.
The latch bar 378 is also actuated to disengage the latch plate from either of the notches in the lever 168a and therebyrelease said lever by the depression of any one of the decimal tabulator keys. In the construction shown in Figs. 8, 9 and 10, the universal bar Zita is suspended upon hangers Zlfia pivotally supported upon arms 214a fixed to the rocker 2523a, this rocker being acted upon by the usual return spring. Upon one of the arms 2l la is formed a projection 390 having a cam face 392 arranged to engage a rol1 394 mounted upon the rear end of the latch plate are,
As the universal bar 278a is swung downwardly by the depression of a type key, the arm Elia is swung downwardly therewith about the axis of the rocker 236a. When the parts are in their normal positions with the key lever |68a elevated, the latch bar 310 is held back by the engagement of the latch plate 382 with the lever so that the cam 392 does not then engage the roll 394. When the lever |68a is depressed and the latch bar 370 has advanced to engage the latch plate 382 in one of the notches 384, 388 in the lever, the roll 394 is then carried forwardly into position to be engaged by the cam 392. With the parts in this position, upon the depression of a type key and the downward movement of the universal bar produced thereby, the cam 392 will be swung downwardly into engagement with the roll 394 and the latch bar 310 will be moved rearwardly to release the key lever I63a.
The latch bar is also actuated to release the key lever I68a, by the depression of a decimal tabulator key. Fig. 8 shows a decimal tabulator key lever 296a and a bail 302a pivoted at 304a which, upon the depression of a tabulator key lever, is engaged by said lever and swung downwardly. Upon one of the side arms of the bail 302a. is fixed a cam arm.396 having a cam face 398 arranged to engage the roll 394.
When the parts are in their normal positions, with the lever I680, elevated and the latch bar retracted, the roll 394 is located out of the path of the cam arm 395. When the key lever I68a is in depressed position and the latch bar 310 has advanced to engage the latch plate 382 in one of the notches 384, 386, in said lever, the roll 394 is carried into the path of the cam arm 396. Then upon the depression of the bail 392a produced by the depression of any one of the tabulator keys, the cam face 398 on cam arm 396 is engaged with the roll 394 and the latch bar 310 'is moved rearwardly to release the lever 58a.
The construction shown in Figs. 8, 9 and 10 comprises a line space brake release lever 38|a constructed and pivoted in substantially the same manner as the lever 36I shown in Figs. 1 to W 7 inclusive. The lever 361a is provided with a lateral bend extending over the horizontal arm of the bell crank lever 314 and arranged to engage said arm upon the depression of the forward end of the lever 36|a when the parts are in the positions shown in Fig. 10. By the engagement of the lever 36! with the bell crank lever the latch bar will be actuated to release the lever l68a. When the lever 168a is in elevated position, the bell crank lever is located in the position shown in Fig. 8 in which the horizontal arm thereof is not engaged by the lever 36m upon the depression of the forward end of said lever.
