Application filed July 2, 191a,. serlai No. 776,903.

To all whom it may concern:

Be it knownthat I, CHARLES E. SMITH, a subject of the King of England, residing in New York city, in the county of New York and State of New York, have invented certain new and useful improvements in Tvpe-VVriting Machines, of which the following is a specification.

, My invention relates to mechanism for -.throw of the carriage, each device being preferably adjustable to vary the distance .the carriage will jump when the correspond ing'key is operated. By the use of separate jump-controlling devices, the adaptability .of the machine for various uses is increased.

For example, one of the keys may be used for spacing between sentences, the device controlled thereby being set for three, four, or any desired number of let ter spaces. A second key may be used for paragraph indentations, the device controlled by Said key being adapted to effect a suitable spacing for this purpose, as, for example, the distance of eight or ten letter spaces. Either one or both of these superspacing devices may, in addition, he used forefl'ecting a rapid run of the carriage in various other kinds of work. Thus, by repeatedly depressing the key which is set for para raph indentation, the carriage may be quick y advanced great distance. This movementwill be m ch more rapid, and ac complished with less effort than by the use of'the ordinary single-space key. One or more of the multiple-space keys may also in some cases be used in tabulator work. Thus one key may be used alone for moving the carriage from one column position tonnother, or additional keys may, be selectil'ely Specification of Letters Patent.

sitions in a column, the particular key operated at any time depending on the position of the first digit or character in the particular line and column to be written.

W hen eitherof the special keys is operated, the spring-driven carriage is released from the escapement mechanism and put under the control of a. s ecial super-spacing device, which permits t e carriage to space or jump a fixed distance; and when said key is released the carriage is withdrawn from the control of the super-spacing device and restored to the control of the ordinary ls ter-feeding mechanism. Each special key controls a separate super spacing member, and the latter is preferably ad ustable to vary the distance-the carriage j umps.-

Normally idle racks are mounted on the machine frame, to be independently caused by the separate special-spacing keys to shift into locking connection with superspacing devices or stop-plates on the carriage, each stop-plate permitting the carriage to jump or advance a fixed distance. Each special space also operates to release the carrings and permit it to jump. The stopplates are mounted on a guide on the carriage, and each stop-plate carries a stoppin which extends into a slot in said guide, the pin being adjustable on the stop-plate to vary the distance the stop-plate can move relatively to the carriage. One of the rack bars nay also be formed with rack teeth the column stops of the ordinary tahniating mechanism, said. stops being adj ustable longitudinally of the rack, and also settable into and out of position to cooperate with the ordinary tabulating counter-stop on the carriage.

The same key -may, if desired, be used alternatively as a tabulator key or as a multiple-space key for sentence spacing, etc,

and in ieh a case, in order to silence the super 5; devices, the tooth or detent on said a? *c with which the rack engages,

; of operative position.

.aple-space keys may be used sepfor different purpQ-ses, as, for exc, sentence spacing, paragraph indenation, spacing between 'columns in tabuator work, etc, each stop being adjustable .1: cause the carriage to jump any desired distance, depending on the purpose for which it is used.

Other features and advantages will hereinafter appear.

In. the accompanying drawings which illustrate one form of my invention, Figure 1 is a rear; elevation view showing a portion of an Underwood typewriting machine with my invention applied thereto. Fig. 2 is a view similar to th right-hand portion of Fi l, but showing one of the slidable stop-p ates in operated position. Fig. 3 is a fragmentary sectional elevation showing means for swinging the rack bars, and other details of the invention, the lower rack bar being in operated position, and a column stop set to operative position. Fig. 4 shows a guide plate on which the slidable stopplates or jump-controlling devices are mounted. Fig. 5 is a perspective view of one of the stop-plates. Fig. 6 isa sectional elevation view-'ofthe machine. Fig. 7 is a perspective view showing means for releasing the escapement rack and operating the swinging rack bars. Fig. 8 is a view similar to Flg. 6, but with one of the swinging racks in operated position.

Type-keys 1 are mounted on key levers 2 fulcrumed at 3 and operable through bell cranks 4 to move the type-bars 5 upwardly to printing position in front of the platen 6. The platen is shiftably mounted on a carriage 7 driven in letter-feed direction by a spring motor 8 connected through a belt 9 to the carriage, the carriage being guided on a rear guide rail 10 and a front guide rail, not shown. The letter-feed travel of the carriage is controlled by escapement mechanism comprising-escapement dogs 11 cooperating with an escapement 'wheel 12 driven by an escapement pinion 13 which runs in mesh with a rack 14 on the carriage. Each typebar has a shoulder 15 which, when the typebar is actuated, moves a universal bar 16 z-iarwardly and operates the dogs 11, the re ciprocation of said dogs effecting a letter feed movement of the carriage in the usual way. The escapement rack 14 is connected to the carriage by a swinging frame 17 which permits the rack to be lifted from the escapement pinion 13 so that the carriage may move independently of the es capement mechanism.

In order thatithe" ctiirriage may be moved forwardly a multiple? letter-space distance by the single operation of a space key, the following mechanism is provided. A rockshaft 18 mounted on the machine frame, preferably in rear of the platen and parallel therewith, has secured thereto upwardly and rearwardly extending arms 19 to which is fixed a rack bar 20 adapted to be swung forwardly to engage a tooth 21 on a stop-plate 22 slidably mounted on the carriage, to permit a limited travel of the carriage while said plate is locked to the rack bar. The rack bar 20 is swung inwardly by means of a multiple-space key 23 on a lever 24 fulcrumed on the rod 3 and connected through a link 25 to an arm 26 fixed to the rock shaft 18, so that when the key 23 is depressed the rack 20 will be swung inwardly to engage the tooth 21. The key 23 also operates to lift the escapement rack 1 1 to permit the multiple letter-space movement of the carriage. The escapement rack is lifted by a roller 27 on a rock plate 28, over which extends an arm 29 fixed to the rock shaft 18.

The slidable stop-plate 22 is mounted on a guide plate 30 fixed to the carriage frame and having shouldered screws 31 extending through slots 32 in the stop-plate 22, thereby permitting the stop plate to move relatively to the carriage in a direction opposite to the forward travel of the carriage, or, in other words, when the stop-plate is held by the rack 20, the carriage is permitted to jump forwardly a limited distance. The distance the carriage is permitted to move is determined by a stop pin 33 which may be set in any one of a series of openings 34 inthe plate 22, said stop pin extending into a slot 35 in the plate 30, so that when the stopplate 22 is connected, to the rack 20,'the travel of the carriage is limited by the end of the slot 35 being brought up against the stop pin 33.'

When the space key 23 is depressed and the rack 20 thereby swung inwardly to engage the tooth 21 on the stop-plate 22, the escapement rack 14 is also lifted to free he carriage so that the latter is moved forwarr ly by its spring 8 a distance determined by the position of the adjustable stop pin 33. l/Vhen the key 23 is released, it is returned by its spring 36, the rack 20 swings out and releases the stop-plate 22, and the escapement rack 14 reengages its pinion to lock the carriage. The plate 22, being released, is returned by a spring 37.

The teeth on the rack 20 are preferably at letter-space distances apart so'that the tooth 21 may engage the rack 20 while the carriage is at any normal position of rest throughout its range of travel. The openings 34 for the stop pin 33 are also preferably letter-space distances apart, as measured in the direction of the carriage travel, so that the stop pin may be adjusted to effect a movement of the carriage equal to any desired number of letter spaces within the limits of adjustment of the stop pin.

In order to provide for jump movements or multiple letter-space movements of the carriage through different distances, and mdependently controlled by separate keys, additional mechanism is provided wlnch is in many respects similar to that already described. This additional mechanism may per rack )1" act of rack teeth 38 cooperating with a stop-plate l8, and a lower rack or set of rack teeth 38" forming part of the tabulating mechanism.

A return spring 37* is provi Ml for the plate 48.

For eX- I The tooth e ured directly to the hm the fin Z :5 sh wn in Fig. 1 set in hosinon to ruert the movement of the carriage tha ing five letter spaces; the key 2 3 controlling said stop might there fore beused for the usual spacing between sentences. The lower stop pin 33 (as shownl being set to eilect the movement of the carriage through ten letter-spaces, the key 16 might be used for indenting at the beirinning of paragraphs. dither key might also be used in billing and other work for rapidly moving the carriage through a considerable distance by depressing the key a number of times in succession. The multiple-space inenfhanism is also adapted for ui'ious other combinations and uses. The k y mavalso be used as a tabulator key to cause the carriage to run forwardly to predetermined fixed positions; the rack bar 38 in this instance forming part of a. tabulator mechanism, and for this purpose being provided with a lower rack or set of rack teeth 38 for holding in adjusted p0- sition column stops 53 slidably mounted on a rod 5% parallel with the rock shaft 18. The stops 53 have teeth to interlock with the rack teetlriS when the stops are swung forwardly to operative position, as shown in Fig. 3. Each stop 53 also has a forward extension 56 movable into the path of a counter-stop 57 on the carriage, S0 that when a column stop 53 is locked to the rack 38, and the rack swung forwardly by operatin the key 46, the travel of the carriage wil be limited by the counter-stop 57 striking the columnstop, as shown in Fig. 3.

When it is desired to use the key 46 as a tahulator key, the tooth 49 on the sliding stop plate 48 is moved to inoperative position, and one or more of the column stops 53 are adjusted along the rack bar and locked thereto. Each of the column stops 53 may be provided with a pointer or indi; cator 58 which, when the stop is in operative position, lies over a scale 59 extending along the rack bar 38. to indicate the position of the stop. The operation of the key e6, will now release the carriage and permit it to move forwardly until arrested by the first column stop in the path of the counterstop on the carriage. 'hen the key -16 is thus used as a tabulator key, the key 23 may be used for spacing between sentences, etc.

Although I have shown two swinging racks which may be separately operated, the invention is not limited to two. The adjustahle stops on the carriage may also be used in tabulator work, the multiple-space keys being operable to move the carriage from one column to another, and the stops being adjusted for different spacings so that the carriage will move from one column to a position in the neXt column. corresponding to the multiplws iiace key which erated.

is op Althou h I have shown two racks 38 and 38* arranged respectively to cooperate with the multiple-space stop plate and to adjustably hold the column stops, my invention is not limited to the use of two racks for this purpose.

Varia ions may be resorted to Within the scope 01' the invention, and portions of the improvements may he used without others.
