Be it known that I, ALaxA-smcn'l. Bnowna citizen of the United States, and a resident of`I Syracuse, in the county of Onondaga and 4State ci New 1 orl, have invented certain new and f useful Improvements in Type-"iitinghlachines,of which the following is a specification.

My invention relates to carriage-feed mechanism for typedvriting machines; and one-of the objects of said invention is to provide rapid and e'cient mechanism of the character specified.

Another object'of` my invention is to provide an etcient escapement or carriage-feed mechanism by which thecarriage may be fed one or more letter-space distances for cach impri-nt of a character. v

A still further object of the invention is to provide an eiicient gig-back mechanism for reference characters indicate correspondingvv parts in the various views, Figure 1 is a vertical front-to-rear sectional view of one form et type-Writing machme embodying my in- Ventron.

Upon reference to Fig. 2 it will be observed that an auxiliary key 135 extends to the right ot' the space-key 1015 and is provided with guide-pins 136, that are received in openings in guide-plete .105?. This key is likewise provided with s depending erm 138, which is pivoted at 1&9 to s c enk-srin 140, that projects from s rocleshsit 140, which extends :troinfront to rear of the machine an( pin-sl-lel with the rock-shaft 102, hereinbefore described, and is received et its ends within beerings in the front end'rear plates '1n and 1, respectively, of the. nischine-freine.

Pivoted upon this saune spindle 64 is a grsvity-pawl 152, the nose of which is adepted to rest upon the periphery of the coller 55 and to engage the teeth 57 thereon, and thus prevent or limit the reverse rotation of the primary esczipeinent-Wheel. The coller of this gravity-pend 152 is slotted at 152L for coperfttion with s pin 152", that extends from the spindle (BA1, on which the pewl is mounted. Thus the gravity-pawl cannot be forced from the position where it cannot be carried by its own weight beck into engagement with the teeth 57 on the collar. A spring 153 snrrounds the rocleshatt 1110 and is connected st one end to the crsn'ker-rn M1 and bears at its opposite end upon e pin 154, so to restore the parts to the position represented in Fig. 2 when the key 135 is released.

Having described the various features et' constructiom'l will now describe the operition thereof. The terms "prirnsry escape-- inent-\vheel and secondary escepeinent- Wheel are used to distingnisli-thern, sind the pinion 7 will be referred to herein es e. plsnetery pinion. I

W hen the inger-key is released, the dogs will ce vibrnted beck to the norrnel pesition'represented in Fig. 1, when the primary escapeinent-wheel 39 will be permitted te move the distance between two teeth thereof. This rotation ot the prirnsry escepement-Wheel causes the planetary pinion 741 to be rotated on its pintle 7 2 and at the stime time-by resson of the fact that it meshes with the teeth or' the secondary escsneinent-wheel, which is Vrelaitively fixed est this time, the pinion Will receive e. rolling'sction around the pinion 58, thereby moving the disk or carrier 66 with the planetary pinion thereon from the position shown in Fig. t to that represented in Fig. 5, for instance. This movement et the carrier 513 trsnsinits e corresponding movement to the pinion on the shaft thereof, and from the pinion 7() e et the l gear-Wheels 85 Aand. 90 is 'afforded under tension ofthe spring 92 to Apermit the carriage to jmove in the direction of its feed a letterspace distance. This actuation is repeated on the'depression of anycharaeter-key. y

A depression ofthe space-key 105 will cause the feed-dog 95jto be forced into the pathof a tooth 76 on the secondary escapeare'Av ment-wheel before it has the opportunity to rnove.` This movement of the feed-dog 95 throws the .dog 96 out vof engagement with the tooth l'(6 engaged thereby, as represented in Fig.V 4. When the space-key is released,

willthus be'` seenv -tliatthe space ,and character heysjare independently operable, the space -jkey actuating the secondary escapeinent-wheel 'ind'ependently of the primary eseapement-wheel, whereasl the character-keys aifordan actuation of the primary escapement-,wheell independently of the secondary escapement-wheel.' Should the'operator desire to provide a double'space as the last letter of a word is being written, for example,

in order-that the machine` may be at once operated to begin writing 'the next wordritis merely necessary to simultaneously depress' a characterkey and the space-key, thereby imprinting thedesired character, and when said keys are released a double-space movement o't--the carriage will be given and the i nextfword may immediately be written.

Should the operator desire togig-'back the carriage through any desired number-of letter-space distances in order to-bring the carriage to the desired poi-ntfor'the :insertion lof a letter or the like, `it is merel-yneeessary to.

depress the finger-key 1.35, .which will-cause the gig-back' pawl 145 tofengage' the teeth T6 on the secondary escapementwheel and to turn it in avdirection-opposite, tothatindi- `cated bythe arrow in 'Fi-g. 2.,' This reversel rotation of the secondary .eseape'ment-wheel is efec'tiveto vturn the pinion 7 44 around-the' pinion "asa eenterv..and ina;direction 'i'efverse to that previously'desc-ribed,or. vfrom 'carrierto which iit is connected from the po-VA sition represented in Fig. 4 to that indicated in Fig. '5., for instance, and a corresponding --be in a forward or backward direction.

right to left` so that the pinion Tl and carrier (Stato which it is pivoted.receive a bodily movement around the axial center of the shaft 5G, thus'turning the shaft 69.to which the dish is connected, and the pinion TO on said shaft will transmit a reverse rotation to the gears S5 and 90, thereby feeding the carriage fromleft to right or in a direction reverse to its ordinary feed movement. 'lhegig-back mechanism thus affords a step-bystcp backward movement of the carriage, the carriage being moved a letter-space distance at each depression of the key 1 35.

From an examination of Fig. it will be observed that the primary escapement-whcel 39, `secmidary escapement-wheel T5, the pinion 58, and the internal gear 77 revolvemupon t-lie same center and that the .so-called plan-l etary l pinion T4 is intermediate the pinion 58 and gear TT and receives a planetary movement around the pinion 58 when either escapement-wheel is actuated, solas to afford a move- .mentof the dish or carrier 66, and thereby afford a step-by-step movement of the carriage, whether the movement of the carriage Furthermore, it will be seen that either escapement-wlieel maybe actuated independently of vthe other by independent. key-actuated means to aliord a single-spacing movement of the carriage; that the carrier (5h may either he moved with or independently ofthe secondary escapenient-whcel by key-actuated mechanism; that the secondary wheel may be moved plications liled. by me herewith or embodied inapplications previously iiled by me.
