JOHN WALDHEIM, OF ELIZABETH NEW JERSEY, ASSIGNOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPEWRITING-MACHINE.

Application filed May 10,

- citizen of the United States, residin ,in

Elizabeth, in the county of Union and tate of New Jersey, have invented certain new and useful Improvements in Typewriting- Machines, of which the following is a speci' ficationl This invention relates to typewriting machines, and more particularly to means to automatically return the carriage and linespace the platen.

One form of the invention is'herein shown as used with mechanism disclosed in the patent to Kupetz, No. 1,186,516, of June 6,1916, in which there is provided a left-hand margin-gage engageable by the typewriter carriage to close a switch to return the carriage by an electric motor. The carriage engageswith a right-hand margin-gage during the latter part of its return movement to open the switch to stop the motor.

It has been proposed to return the carriage from any one of a plurality of letterspace positions in a zone, in which all of the writing lines terminate, by the actuation of a punctuation-key or a space-bar while the carriage is in the zone, the punctuationkey and the space-bar being dependent for their efficacy to start the motor on the pos1 tion of the carriage. With such an arrangement, should a punctuation-key or the spacebar be the first to be actuated when the carriage enters the zone, it is immediately returned, thus leaving blank or unused the remaining letter-space positions in the zone.

An object of the present invention is to provide means, whereby the number of typed letter-spaces in said zone is increased. For this purpose a condition may be set up inthe machine, by the actuation of a vowel-key or the shift-key while the carriage is in the zone; this condition being such that the motor may be startedto return the carriage by the actuation of a punctuation-key or the space bar; the punctuation-key and the space-bar being dependent for their efiicacy to start the motor upon the actuation of a vowel-key or the shift-key, and the vvoweltype key and-the shift-key being dependent upon the position of the carriage for their efiicacy to set up the condition in the machine.

In carrying out" the invention, two uni- Specification of Letters Patent.

versal bars may be provided, one for the vowel-keys and the caseshift-key, and one for the punctuationkeys. These universal bars are normally out of eil'ectivev relation with the associated keys, but as the carriage enters the zone, it actuates the left-hand margm-gage to move one of the universal bars into efiective relation with the voweltype-keys and the shift key, so that itmay be actuated by any one of them. This universal bar, when actuated, is effective to move the other universal bar into effective relation with the.punctuation-type-keys, so that by the actuation of any oneof the punctuation-type-keys, the last-mentioned universal bar is actuated to close the switch and start the motor to return the carriage. The.

carriage, as it approaches the end of its return movement, engages with the right-hand margin-gage to automatically open the.

the zone, and consequently a word, which it was intended to hyphenate, may be completely typed on the same printingline. As soon as the carriage enters the zone, however, the hyphen-key becomes unlocked, so that it maybe used if the word being typed is exceptionally long.

Other features and advantages will hereinafter appear.

The invention may be used on an Underwood machine in which alphabet-type-keys, including vowel-type-lreys 15, and punctuation-type-keys 16, when depressed, swing frame, in its case-shi key-

levers

17 and 18,.respectively, about their pivot 20 and against the tension of suitable return springs 21, to rock bell-cranks 22 and swing type-bars 23 about their fulcrum 24, to cause lower-case types 25 and uppercase types 26 to print, at a common printing point, against the front side of a laten 27, rotatably supported in a platenrame 29, on a carriage 30. The carriage 30 may be drawn from right to left of the machine, to feed it from one letter-space position to another during typing operations, by a spring-drum 31 connected to the carriage by a strap 32. These movements of the carriage may be controlled by escapement mechanism comprising an escapement wheel 33, having the usual one-way connection with a pinion 34, which meshes with a pivoted feed-rack 35 on the carriage 30. As the type-bars 23 approach the printing point, heels 36 thereon engage a curved universal bar 37, of .a universal frame 38, to move the latter rearwardly and cause a cross-bar 39, on said frame, to move a dogrocker 40 rearwardly against a suitable spring (not shown), which returns the dogrocker to normal position. This causes a loose dog 41 and a fixed dog 42 on said dog-rocker to reciprocate between teeth 43 of the escapement wheel 33, to permit the carriage to feed single letter-space distances at each reciprocation. The rear end of the universal frame 38 is pivotally supported on upwardly-extending arms 44 secured to a rock-shaft 45, suitably supported in the usual escapement bracket (not shown).

A space-bar 46 is provided, whereby the carriage 30 may be fed without typing. The space-bar 46 is located in front of the type-keys and is carried by two arms 47 extending rearwardly to a rock shaft 48, upon which they are secured, so that the space-bar when actuated against the tension of a suitable return-spring. (not shown), rocks the shaft 48 to cause an arm 50, secured near the middle of the rockshaft 48, to engage with a downwardlyprojecting arm 51, on the rock-shaft 45, to actuate the universal frame 38 and the dogrocker 40 to effect a letter-space movement of the carriage 30.

' The platen 27 may be shifted to its uppercase position, so as to enable typing with the upper-case types 26. For this purpose, there is provided a shift-key 52 which, when depressed, swings a shift-key lever 53 about the fulcrum 20, to cause an upwardly-extending arm 54, on said shift-key-lever, to swing a shift-frame 55 about its pivot 56. The shift-frame is provided with a crossbar 57 which engages with a roller 58 se cured to the platen-frame 29, to move the platen-frame upwardly and shift the platen 27 to its upper-case position. The platenting movements, may

The plunger 66 has pivotally mounted thereon a pawl 68, which engages with a toothed line-space-wheel 70, secured to the platen-shaft 28, to rotate the platen from one line-space position to another.

The platen 27 may be automatically linespaced, and the carriage returned to a new printing position. For this purpose, there may be used an electric motor 71 connected in a circuit comprising two wires or conductors 72 and 73, extending from a plug 74, whichmay be connected to a source of electric current. A normally open switch 75 comprising a pivoted member 76 and a fixed contact or terminal 77 may be connected in a motor circuit. The switch may be closed by means, hereinafter described, to start the motor 71, and wind up a strap or band 78, one end of which is connected to a drum 79, secured to the motor-shaft 80. The other end of the strap 78 is connected'to a link 81, to move a slide-bar 82 rightwardly, against the tension of a returnspring 83; said strap 78 being guided over rollers 84 and 85 on a bracket 86 secured to the machine frame 87, and a roller 88 on a bracket 90 secured to the motor 71. The slide-bar 82 may be guided in a lug 91, on the carriage 30, and is provided with a projection or-hook 92, to engage the linespace lever 63, to actuate the latter to linespace the platen 27, when the slide-bar 82 is moved riglitwar'dly. After the platen has been line-spaced by the motor 71, the carriage is drawn rightwardly to the beginning of a new line.

The carriage may be returned from any one of a plurality of letter-space positions within a carriage-return-zone, the breadth of which may be determined by a margingage 93 at the left-hand side of the machine, which is slidably mounted on a rockshaft 94, and adjustable thereon and relatively to a raclcbar 95, rigidly secured to the rock-shaft 94; the zone being at the right-hand side of a work-sheet, and all the writing lines terminating in said zone.

As the-carriage enters the zone, a projection 89 thereon engages with 21051111 99 secured to the left-hand margin-gage 93 (Figs. 1 and 13), to rock the shaft 94 and the rack-bar 95 in a counterclockwise direction. The rack-bar 95 has secured thereto versal bar 100.

a downwardly-projecting arm 96, provided at its lower end with a flange 97 with a cam-slot 98 therein, which, as the flange moves rearwardly (Fig. 3), shifts a universal bar 100 axially on pivot studs 101 and toward the right-hand side of the machine (Fig. 4), by means of a finger 102 projecting from the universal bar 100 into the cam slot 98. The universal bar 100 is moved into effective relation with the vowel-type-key-levers 17 (Figs. 3 and 4), and against a return-spring 103, which may be of any suitable form, located at the right-hand side of the machine (Figs. 1 and 9). The universal bar is provided with rojections 104 which are moved under the vowel-type-key-levers, but normally occupy the spaces between the vowel-type-keylevers 17 and the adjacent key-levers (Fig. 9). 85

The universal bar 100 is held in its effective position by an arm 105 (Fig. 13), secured to the end of the rock-shaft 94. and provided with a yieldable detent 105 adapted to ride into and out of shallow de ressions 105 in the machine frame. hile the universal bar is so held, through the medium of the arm 96, the finger 102 engages in a dwell 106 (Fig. 1) of the cam slot 98. Any end thrust, which may be imparted to the downwardly-projecting arm 96 when shifting the universal bar 100, may be taken up by an offset 107 on the flange 97 which may engage with the lefthand wall of the frame 87. 6

After the carriage has entered the zone, a vowel-key must be actuated before the return of the carriage can be effected by the actuation of one of the punctuation-keys 16 or the space-bar 46.

Any one of the 1 vowel-keys, when actuated while the carriage is in the zone, is effective to swing the universal bar 100 in a counterclockwise direction (Fig. 5), against the tension of a return-spring 108, which normally holds 110 the universal bar 100 against a stop-pin 110 (Fig. 1). The universal bar 100 is provided at its left-hand end with a cam 111, which engages with a lip 112, on an arm 113 of a second universal bar 114. to 115 move the latter axially on its pivot studs 115, against the tension of a spring 116, and into effective relation with the punctuation-key-lever 18 (Fig. 6), and the spacebar 46. The dwell 106 of the cam-slot 98 is of such a length as to permit the finger or projection 102 to move freely forward therein during the actuation of. the uni- The universal bar'114 is provided with projections 117 which normally occupy the spaces between the punc tuation-key-levers 18 and the. adjacent keylevers, and are moved under 'the punctua' tion-key-levers when the universal bar 114 is shifted. The universal bar 114 is also an abbreviation inthe zone, such as Dr.

provided with a hook-like projection 118 which is normally out of effective relation with the right-hand arm 47 of the spacebar 46, and which is moved under the arm 47 when the universal bar 114 is shifted to its effective position.

The universal bar 114, associated with the punctuation-type-keys and the space-bar, may be held in its shifted position, or, in other words, in its effective relation with said keys, so that the actuated vowel-key 15 and the associated universal bar 100 may return to their inactive positions (Fig. 3). For this purpose, there is provided a springpressed latch 120, Figs. 1, 5, 10 and '11, pivotally mounted on a motor-controlling member 121. The arm 113 of the universal bar normally occupies the position shown in Figs. 1 and 10, but, as the universal bar is moved to its effective position, the latch 120 snaps in back of said arm 113 to hold the universal bar 114 in its shifted position (Figs. 5 and 11).

If a punctuation-key or the space-bar is actuated after the associated universal bar 114 has been shifted to its effective position, the universal bar 114 is swung in.a counterclockwise direction about its pivots 115 and against the tension of a returnspring 122, Which tends to hold said universal bar in its normal position against a stop-pin 123. During this movement of said universal 'bar, the arm 113 thereon moves the mbto'r-controlling member 121 rearwardly, to permit the switch-member 76, engaged by a lip 124 of said controlling member, to be swung about its pivot 125 by a spring 126 (Fig. 1), and against the terminal 77 to close the motor-circuit. The motor then starts rotating to wind up the strap 78, and consequently line-spage the p1aten27 and return the carriage 36 to a new writing position. The controlling member 121 may be guided. in

suitable brackets

127 and 128, and is moved against the tensionbf a return-spring 1 30, which holds the controlling member in its normal position (Fig. 1), where it is arrested by a pin 131 which bears against the bracket 127.

In any word, one of any three succeeding letters is almost invariably a vowel. From this it will be seen that the machine is set up to return the carriage after the third letter has beenwritten in the carriage-return zone.

It may be desirable at times to write only Ct, or St, which do not have a vowel. In such a case the shift-key 52 may be utilized to set up the condition in the machine,

so that when the period is typed, the return of the carriage is effected. For this purpose the universal bar 100 is provided with a projection 132 (Figs. 1 and 9), which is normally to one side of the shift-key-lever 53,

but is moved under the shift-key-lever when the universal bar is moved to its effective position, after which the shift-key may-be depressed to actuate the universal bar to close the motor-circuit as herein described.

It is desirable to keep the motor-circuit closed and the motor running without any attention on the part of the operator, while the carriage is being returned. For this purpose, there is provided a locking pawl 133, in the form of a bell-crank, pivoted at 134, which is normally held ineffective (Fig. 2), by a finger 135 on the downwardly-projecting arm 96. The finger 135 engages with a pin 136 on the pawl 133, and asthe arm 96 is actuated, the finger 135 moves away from the pin, 136, so that the pawl 133 may be swung about its pivot by means of a spring 137. As the controlling member is moved rearwardly, a projection 138 thereon catches in back of said pawl 133 (Fig. 7), to retain the controlling member 121 in its actuated position, thus permitting the switch to remain closed.

To stop the motor 71, the carriage 30 has thereon a projection 140 (Figs. 1 and 14), which engages, during the latter part of its return movement, with a cam-member 141, to actuate the latter, which is adjustable with a right-hand margin-gage 142 (Figs. 1 and 14). The cam-member 141 rocks the shaft 94, to which it is slidingly connected, back to its normal position, thus restoring the downwardlyprojecting arm 96, sup.- ported on the rack-bar 95, to its normal position. During this action, the fin er 135 on the arm 96 engages with the paw 133' to move it out of effective relation with the controlling member 121, to permit the controlling member to return to its normal position under the influence of the spring 130 when the lip 124 engages with the switch-member 76 to swing it about its pivot 125 and open the switch 75, and consequently stop the motor 71. Y

It will be understood that as the universal bar, associated with the punctuation-keys 16 and the space-bar 46, is restored to its inactive position by: its return spring 122, the arm 113 on the universal bar 114 moves out of efiective relation with the holding latch 120, and consequently the universal bar .may be moved axially back to its normal position by the spring 116. Upon the release of the controlling member 121, the latch 120 resumes the position shown in Fig. 10.

The right-hand margin-gage 142 is adjustable lengthwise of the carriage, so that it may be set according to the width of the margin desired at the left-hand side of the work-sheet. In this way, the position at which the switch is opened to stop the motor may be varied. A shock-absorber or buffer 143 (Figs. 1 and 14) is carried by the margin-gage r 1 ,aoepee stop, against which the projection 89 on the carriage may engage to absorb the blow of said carriage on its return movement.

A separate carriage-return-key 144 (Fig. 1) is provided to return the carriage from any letter-space position, irrespective of whether the carriage is in or out of the carriage-return zone. This 'carriage-return-key, when actuated, (Fig. 12), swings a lever 145 about its pivot 146, and against the tension of a spring 147 connected, to an arm 148 of said lever; the spring 147 being effective to hold the lever in its normal position against a stop-pin 150. The arm 148 engages with a lateral projection 151 on the switchcontrolling member 121 to move it rearwardly to permit the switch to close; During the depression of the carriage-return-key 144, the holding pawl 133 is also rendered effective. This may be accomplished by means of a pin 152 on the lever 145, which engages with acam 153 on the arm 96 to swing the latter with the rockshaft 94 about its axis, to move the finger 135 away from the pin 136 on the pawl 133, and permit the latter to be swung to its effective position by the spring 137. This may take place during the early part of the depression of thecarriage-return-key 144, af-

ter which the controlling member 121 continues to move rearwardly until the pawl 133 snaps in front of the projection 138 on the controlling member. The carriage-return key 144 may now returnfrom its depressed position (Fig. 12) to its normal position; the arm 96 being held in its actuated position by the detent 105 (Fig. 13) as previously described. When the projection 140 on the carriage engages with the cam-member 141 on the right-hand margin-gage 142, the shaft 94 is' rocked and the downwardlyprojecting arm 96 is swung back to its normal position, thus disengaging the pawl 133 from the switch-controlling member 121, to

permit the circuit to be opened, and consequently the motor 71 is stopped.

If the operator should, in order to hy- .phenate a word, actuate the hyphen-key 154,

when the carriage is close to, but not yet in, the zone, the operator being under the impression that the carriage has already en tered the zone, it will be seen that the car riage will not be returned by the actuation of the hyphen-key. The carriage may be returned, however, by the actuation of the carriage-return-key 144. In such a case, there would be a .number of unused letterspacepositionsleftontheprintingline. Ihave found it advantageous to provide means to lock the hyphen-type key 154 within a range of several letter-space positions of the carend of a line, when the carriage has not yet entered the zone, the operator finds that the hyphen-key is locked and is thereby informed of the approximate position of the carriage, and that the word being typed may be completed on the same line without hyphenating it.

To look the hyphen-key 154, there may be provided a member 155, pivoted on the rocksh'aft 94, which straddles the left-hand margin-gage 93. The member 155 has thereon a cam 156, the length of which determines the range in which the hyphen-key may be locked in the travel of the carriage. The cam 156 (Figs. 13 and 15) bears a definite relation to the cam 99 on the margin-gage 93, and is adjustable therewith. As the carriage approaches the carriage-returningzone, the projection 140 thereon engages with the cam 156 to swing the member 155 about the rock-shaft to cause a downwardlyprojecting arm 157 to engage with a bail 158, which may be pivoted on a rod 160 extending crosswise of themachine, and conveniently supported in the side walls of the frame 87. The bail 158 is substantially as long as the rack-bar 95, so that the arm 157 may engage therewith, irrespective of the adjustment of the margin-gage. The bail may be held inplace on the rod by a "collar 159, and is adapted to be swung, by

which the link is connected. The rock-shaft 164 extends crosswise of the machine and is pivotally supported at its ends in the frame 87. ;'It is provided with a hook-like member 166 arranged above the hyphen-key, so that when the rock-shaft 164 is actuated, the hook-like member 166 is swung under a hook 167 associated with the hyphen-key 154 to lock the latter until the projection 140 on the carriage has moved past the cam 156. The carriage then enters the carriagereturning-zone, and the hook-like member 166 is swung out of locking relation with the hook 167 of the hyphen-key by the spring 161.

i From the foregoing, it will be understood that the locking of the hyphen-key takes place within a range of several letter-spaces. or, in other words, a zone the breadth of which is dependent upon the length of the cam 156 on the member 155. Thus the carriage is adapted to traverse two zones, namely, the key-locking zone and the carriage-return-zone. The two zones arcadjacent to each other and their posltions are determined by the left-hand margingage 93.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
