TYPE-WRITIING MACHINE.

Improvements in TypeWriters; and I do hereby declare the following to be, a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to type-writing machines ;'and the'object of the invention is to pe-writin machines in a number of particul ars, as wil hereinafter appear.

To. these ends my invention consists in the novel arrangement and combinations of parts hereinafterdescribed, and particularly pointed out in the claims. I

In the drawings, A denotes the main frame, which has a top plate A, on which is mounted the carria e. B and: other mechanism, which will be escribed in detail hereinafter.

' The top plate is provided with suitable posts A and A and e front gui e-rail A on which the carriage ovesfrom side to side :of the ma-,

' chinfi 1n the usual way. It will be under-r Specification of Letters Patent. Application filed August 27, 190). Serial No. 28,142;

stood. that the carriage is actuated by the usual spring mechanism C in a manner that need not be particularly described.

Tihecarrrage comprises a substantially rectangular frame B, provided witha pair of traverse rollers B to run on the back rail A? and a s ngle front roller B to run on the front'rail. The carriage is held from dis glac'ement on the rails by apair of brackets,

extending under the rear guide-rail, while at thefront the's'ame object is secured'by 'a" small lug B", that extends rearwardly from the front plate B and engages in a groove A? along the front ofthe front, guide-rail, Fig. 10., Inthe side bars of the carriage-frame aredepressions B (see Fig. 1) to allow'for 'the vertical movement of the sh'aft'of the platen D as the same is shifted vertically for upper'and lower case printin he shaft D of the platen is mounted in bearings formed in a stirrup or platen-frame E, having longitudinalconnecting bars E at the rear and E at the-bottom, as shown in Figsfl and 6.

crank-arms F, that are secured to a rockshaft F whereas the upper portion of the platen-frame is pivoted at each side'to one This platen-frame is pivotally connected at the lower portion thereof to end of a link F, the opposite end ofwhich is pivoted at B to the carriage, the links i i F and crank-arms F constituting, in effect,

parallel links on which the platen-frame and platen receive their vertical movements to change the printing position. The shifting mechanism is best shown in Figs. 4 and 8,

wherein it will be seen that bearings onthe top plate A support a rock-shaft G from which project crank-arms G, that have connected at the outer ends thereoi a sup-' porting or shift rail G, which supports a roller E", mounted in the lower longitudinal bar E of the platen-frame above mentioned. bracket E depending from the bar E 01 the platen-frame has a lug. E 'pro'ecting under the rail Gf to prevent the roller 43 from being raised ofi of said rail by overthrow due to vie-- lent shifting of the platen or in any other manner. The rock-shaft G has connecteit to one end thereof a crank-arm G which is connected by a rod G with an arm G, that projects from'one end of a rock-shaft G, that is mpunted to turnin bearings G in the frame f the machine at the front thereof. This I 1 5 I downwardly and forwardly rock-shaft G has secured thereto at its opposite end a hand-operated actuating-arm G provided with a shift-key G of the machine.

at the keyboard It will be seen that by depressing the shift-ke G the platen-frameand platen will be e evated and on the release ,of the key the platen and platen-frame will move to the normal position by their own weight. The weight of the platen and platenframe is counteracted by coil-springs F which surround the shaft 2 and tend to counterbalance the weight of the platen and plateni frame. The upward movement of the rail is limited by an arm G which pro'ects from one o the center crank-arms G, abutting against an adjusting-screw G, as will be seen in Fig. 8,} whereas the downward movement of the platen and its frame may be limited by an adjustable screw E, (see Fig. 6,) carried by v the carriage and .with which the platen-frame coeperates.

By referring to Figs. 2, 4, and 9 the mechanism for securin the'platen in shifted position Wlll be clear y se'en. An upwardly-extending arm G may be made as a part of the actuatin -arm G and near this arm is a three-arm lever H, pivoted to a fixed portion of the machine, one extension 'H of which is provided with a lateral lug H that constitutes a stop adapted to intercept the arm G as the said lug is moved forward by the upward throw of the forwardly projecting hand-operated arm of the lever H, while the upwardly-disposed arm H connects by a In H with a spring H fastened at its lower en to a fixed stud H. The construction is such, as will be seen, that one end of the spring is moved to either side of the pivotal center of the lever H, and the spring holds. the lever H 1 in either position to which it may be moved tion.

around its pivot. The stud H in its forward movement engages the arm G", thereby moving and holding down the shift-key G and maintaining the platen in its elevated posi- The step-by-step movement of the carriage is controlled by an escapement which comprises feed-dogs I and I, Figs. 3, 5, 6, and 8, which cooperate with a doublynotched rack I. These parts form no essential feature of this invention, and a detailed description thereof maybe omitted. It may also be noted that the lever mechanism which actuates the escapement also cooperates with other mechanism; but as these features are not claimed herein they need not be described. To the shaft of the platen is attached the usual ratchet D and this is actu- "nating in a downwardly-extending piece L. (See Fig. 4.) A coil-spring L provided with a small antifriction-roller L.

On a bracket L connected to the latenframe E, is mounted a bell-crank lever (see Figs. 1 and 4,) provided with a de ending vertical stud L to enga e the antifi'ietionroller above described. The opposite arm of this bell cranlg has an upwardly-extending pivot post L, that .is connected to the arm by a vertical pivot, whereas a horizontal pivot L constitutes the connection between the pivot-post and the rear end of a horizon tally-mov able dog L, which is moved rearwardlly or in the direction of its feed by the oscillation of the fingeriece L, while the spring L restores it to t e normal osition. In the rearward movement of the og L it engages the ratchet-wheel D connected to the platen, and thus rotates it for linespacing. I

Referring to Fig. 4, it will be seen that a shoulder L and a pin L on the carrier of the de L engage the tail of a pawl L, which is independent of the dog and its actuating means and is pivotedto ears projecting forwardlyfrom the platen-frame, and the engaging nose of said pawl L engages the teeth of the ratchet-wheel D and serves to lock thespacing dog and is positively moved thereby to effect a locking of the platen against overthrow or a ainst rotation in either direction when the 0g has about spacin movement.

To t e rear of the ratchet-wheel D is an independently-actuated hand-operatedangular lever L", (see Fig. 7,) that is ivoted to ears extending forwardly from. tlie platenframe and the upper part of which forms a guide L for the space-dog and to the lower part of which is connected an elastic or re silient brake-shoe L, that is preferably made of a stri of sheet metal. In the upper part of this lever is mounted a roller or detent L, which in the normal position of the lever L is adapted to engage the ratchet and to hold it against accidental displacement, but so that the laten may he turned one or more line space istances in either direction. This lever is under tension of a spring L, at-

tached to the platen-frame E at one end and hearing at its free end--against the lever and exerting a pressure thereon that tends to maintain the (latent-roller in engagement with the ratchet-wheel and to maintain the brake-spring out of contact therewith;

' The guide L" on the lever L has a cross:

I bar or locking-abutment li Fig. 2, that is adapted to cooperate with a transverse locking-notch L in the upperv edge of the linespace dog, where it extends through the.

guide,so.that when the operator desires to write on lines or in spaces of a blank or sheet ,that cannot ordinarily be brought to the printing-line it is merelynecessary to raise vthefree 'end of the line-spacing dog,-thereby turning it around the pivot L". The effect Of this movement is to. turn the lever L on I its i'vot'against the tension of'the-spring L teeth of the line-spacing ratchet-wheel, and

until the'brake-spring is forced against the the'detent-roller L will by the'same movement be moved out ,of contact with thefteeth of the'wheel. By this time a slight relative movement of. the line-space dogand the guide L Will-have been effected andwhich is sufficient tobring the locking-notch in the dog into register with the cross} bar L? of the .notch and will .bear againsttheforward end,

guide, and the cross-bar will beseatedin said wall thereof, thus maintaining the parts in with the brake-spring bearin ,teethof the line-spacing'whee and the de the positions to which theyhave been moved,-

tent-rollermaintained away therefrom. At

the same time the line-spacin' mechanism is loeked against movement an the platen is free to be rotated by either finger-wheel of the platen toth'e desired extent, .and it will V be retained in the position to which it is retated by the brake-spring L By locking pressure exerted'upon the forward or free the line-spacing mechanism out of actuation when the brake is applied for differential spacing the hand-lever may continue to be used to, restore the carriage to the right withqut,however,'at this time actuatin the line erate with the ratchet-wheel, and the linespacing mechanism as a whole free to be actuated. While Iprefer to employ a lockin notch in the dog to 006 erate with thegui e in the manner specific itshould be understood that anyf suitable means" may be employed for this purpose. 1t .will'be seenthat the actuation of either thie-locking-levei; L or the 'detent or brak- 7 ing lever L is entirely independent of the other. I Thus the movement of thelockingthe locking-lever is insufficient to bring the nose thereofv into engagement with the teeth of theratchet-wheel. To-the front'part of the lever in no way affects the detentdever, 6o

whereas when the braking-leveris moved to a position where the brake-spring is applied any movement; that may betransmitted to against the lever is pivotally connected a cam L and when turnedin either direction, as indicated in Fi 7, its'hi hest. surface engages an incline shoulder on the space-dog, and this determines the relative elevation of .said

space-dog so that the same may engage ever tooth for single spacing or every other toot for double spacing, as will be apparent from said Fig. 7 "It will be seen that the throw-of the dog L is the same whether it be employedforsingle'or double spacing and that therefore the locking-lever will be actuated to lock the lever-at the end of the stroke irrespecti've of'the extent of line-spac ng movement transmitted to the platen. It is to be further noted that the construction is such that the same movement is imparted to the spacing mechanism whether the lat-en is lifted for upper-case writing or is in t e lower most position for lower-casewriting, the de pending stud L being adapted to engage with the roll L whenthe platen is in either of said positions; a singlemovement of thefinger-piece is effective to produce the line-spacing movementof .the parts and to simultaneously move the carriage back to the right to begin a new line.

The mechanism for disengaging the es.-

It will likewisebe'noted that capement-so that the carriage may be freely moved back and forth is best illustrated in Fig. 6, wherein it will be seen that the dog I of the escapement is provided with'a lateral studl and adjacent to this is mounted a" rock-shaft 1 provided with a lateral wing I. This'wing connects by a, link I with a lever I, (pivoted to one side of the carriageat I, an

by pushing down 'onthefinger-piece I Fig. 1, the dog I will be thrown out of engagement with the feed-rack and the carria e is free to be moved ineither direction;

he carriage is rovided with the usual paplaten-frame, and'the platen-frame also has connected thereto the paper-feed rollers M, which are mounted on a shaft supported in per-guide or tabe M, connected with the bearin s on arms M secured to arock-shaft M". eeFig. 6.) A short crank-arm M end of the platen, and these-arms M each engage a lever M each of which is also pivoted to the platen-frame and terminates at the projects from the rock-shaft M near each" opposite side of the platen with" the flexible 1 paper guidin and retaining arm or finger M,

- which eXten s transversely of the platen and conforms to thecurve thereof. Attached to one end of the rock-shaft M?,.-to'which the arms M are connected, is a finger-lever M 7 (see Figs. 5 and 6,) and by pressing'down on the lever it will beseen that the pa er-feeding rollers M are moved away cm the pllaten andat the same time the crank-arms f, cooperating wlth the levers M force the guiding-fingers M away "from the platen,

thus entirely freeing the paper, so that it may be-gnoved freely in either direction.

tancein brackets O, which: are connected, to. a curved rock-shaft O mounted in bearings.-

O on. the frame of. the machine. The rock shaft isiplrlovidedwith a suitable finger lever 0?, by w 'ch it may be tilted, the parts being held to normal position by a suitable coil.- sprin 0. Near one end ofthis rackbar is a stud (see Fig. 8,) which extends intothe bifurcated end of a lever-13,: attachedto-one end of arock-shaft P, mounted in'bearings 1?,

that depend from the top plate. The other end of the shaft is-provided with ade endinglever P pivoted to a lon itudinalFy-movable bar P, the inner end 0 which is guidedin a bearin in a bracket J, that extends rearwardly i rom the type-bar se ment J A pawl P pivoted: to this bar, is 8.5

tr moves endwise to the right to en age the tripearm of the bell-crank lever Q, t e other arm. ofwhich forms the hammer for the bell- Q, which is attached to the bracket J-.

When the bar P moves in the opposite direction, the cam-face of the pawlP will come in.

contact With the trip+arm and will cause the engaging end of: the pawl to be moved up around the pivot of. the pawl until it has assed the trip, thus permitting the pawl to be moved back with the bar P without sounding the alarm. The rock-shaft P and the partsconneeted' thereto are restored to normal position by a spring P.

From the foregoing description it will be understood that as the bar N moves longitudinally from right to left it will sound the alarm, while the spring P restores the parts to the normal. position when the carriage is moved to the right. On the slide-bar are mounted slides N each provided. with a pivoted stop N adapted to engage a projection. or stop B (see Fig. 10) of a plate B attached. to the front part of the carriage-frame. Each.

stop N is controlled by a spring N, and theconstruction is such that when the carriage moves in one direction a cooperating stop is positively engaged; but when moved in the opposite direction the stop yields and the carriage passes over it for urposes which will presently appear. The s ide of each stop N is adjusted to any desired position by a dog N which engages the cooperating teeth on the rack-bar N. The right-hand stop N constitutes a margin-stop to limit the movement of the carriage toward the right, whereas theleft-hand stop constitutes a line-stop or a stop which limits the movement of the apted as theagainst the tensioniof the spring P, when; the:

bell will be sounded, and. after aslight; furthen movement the carriagewillbe arrested The operator is thus apprised of theapproaelt Itothe end of the line by the'sounding of the alarm just before the end of: the. lineis reached whether the left-hand. stop. be set for a. long or short line.

It is to be noted. further that in case theline may terminate with. a long monosyllable word on in any case in whioln the word mayfiverrun the limits of the line,

i the word may be carried still'farther past the- Efi'xed limit of the line bv depressing the fin;-

B will deflect the ivotedl obstruction to the movement of the 'oarri line-stop to one side, so that it Willa ord no.

gin-stop an. uninterrupted feed movement. of the carriage to the end of the line may 1 take place, by reason of the fact that thecarcarriage-stop to sound the alarm.

riage-stop B will at this time deflect the marin-stop to one side around-its pivot. It will; be observed that the line-stop N has three diiierent motions- Said stop is moved to? ward the left near the end of a line by the It ma alsobe moved by the key 0 out of the path of the carriage-stop, and it has a third mo.- tion about its pivot to permit the carriage-- stop to pass it freely when the carriage is moving toward the right.

Referring to Fig. 8, it will be seen that the escapement is actuated by being connected. to a cross-bar R which 1s 111- turn connected by links R to a universal bar It, on which rest the space-bar levers-S and the key-levers, which are not shown.
