TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,838, dated December 21, 1897.

Application filed September 11, 1896. Serial No. 605,519. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES SPIRO, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Type-\Vriters, of which the following is a specification, reference being had therein to the accompanying drawin gs.

This invention relates to certain new and useful improvements in type-writing Inachines, having for its object, primarily, to materially simplify and cheapen the construction of the various parts thereof, whereby the device as a whole is rendered more perfect and complete in its details, capable of performing a greater amount of and better work with less liability to wear or to get out of order.

I provide improved mechanism for controlling the ribbon-feed.

I mount the platen in a novel manner and provide mechanism for tilting the same for the inspection of the work.

I provide simple means for shifting from upper to lower case and holding the platen in either position.

I provide for pefect work in manifolding, means being provided for adjustment of the parts in accordance with the number of sheets on the platen.

I provide a manual lateral shift for the ribbon and an automatic longitudinal feed and reverse.

I employ a movably-mounted rack-bar with means for holding it in position and permitting of its adjustment and ready removal for the substitution of another when desired.

I aim at improvements in minor details of construction.

Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

Fig. 19 is an end elevation of the platen and the cradle; and Fig. 20 is an enlarged perspective view of the ribbon-feed mechanism, which is disposed at one end of the machine.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the frame of any suitable or well-known form of construction in which the operating parts are mounted, the top A being supported upon the pillars or posts a, as indicated.

B is the carriage, mounted for reciprocation in usual manner, B being the rear rod,

in any of the well-known ways, and B being the front guide-rod.

(J is the platen, and 0 its journals.

0 are lugs on the carriage and open upon their upper face or provided with notches or rounded bearings 0, into which are inserted the pintles 0 which are eccentrically dismounted in the lugs or ears a of the frame.

f with a key-lever X.

posed with relation to the journals 0, as indicated best in Fig. 1, and project from the cradle D. The front faces of these lugs or ears C are rounded, as seen at c, and upon this curved surface the journals 0' of the platen work as the cradle and paper-table are tilted, as will be hereinafter more fully explained.

E is the papertable. It is pivot-ally connected, as at e, to the cradle, and between its ends is also pivotally connected, as at c, to the arms E, pivotally mounted, as at 6 in the lugs on the under side of the carriage, said arms extending or connected with a bail E which extends transversely of the machine at the rear side thereof, as shown, and with this bail is designed to be engaged the substantially vertically-disposed hooked arm or lever F, the lower end of which is pivotally connected, as at f, with the rock-shaft F, mounted, as atf, in the lower portion of the frame, and to the front end of which is pivotally connected, as at f the link F which in turn is pivotally connected, as at The construction and arrangement of these parts are such that when the lever is depressed the rock shaft is operated and the tilting lever F elevates the bail E and this bail in turn rocks the papertable forward and downward, and that again tilts the cradle so as to bring into view the writing for easy inspection by the operator, the platen having its pivots eecentrically disposed with reference to its journals 0, which latter ride upon the curved front faces of the lugs C of the carriage, permitting of the requisite movement. The journals of the platen are designed to normally stop against the said lugs, and the weight of the platen itself without the assistance or aid of a spring or other extraneous means, either of weight or force, brings the cradle, the paper-table,'and the bail back into their normal positions. The lugs on the carriage in which the cradle is pivoted being open, as described, the parts are maintained in their proper positions by the weigh-t of the platen and cradle without the employment of any latches.

WVhile ordinarily it will be unnecessary to provide any lock or other means for maintainin g the platen in place, inasmuch as gravity will maintain the same in its proper position, no matter what force may be applied by the type-bars, as in manifolding, and as the paper can be inserted in the machine without the necessity for a platen-retaining lock, still in some instances it will be desirable to provide means for maintaining the platen in a position of rest while the paper is being inserted, and in Fig. 16 I have shown a construction designed for this purpose. It comprises an arm G, extending from the bail-arm E and provided with a catch or hook g at its free end and adapted when the bail is at rest to lock the paper-table against the rocking movement, which is necessary to impel and tilt the platen-cradle D by means of thepin g, with which it engages and which extends from the side of the papentable, as seen in Fig. 16. It is designed to employ one of these arms and pins at each side of the machine, but one only is herein shown, as it is deemed sufficient to illustrate the construction.

The bail is provided with the forwardly-extending arms G, having elongated slots g in which work the pins or screws or analogous means 9 projecting from the upper end of the paper-table, all as shown in Fig. 16,and which permit, first, of the unlocking of the papertable by moving the arms G, so that their hooks are disengaged from the pins g, and, secondly, the tilting of the cradle, as hereinbefore explained. The locking of the cradle and paper-table in position is accomplished automatically by reason of the weight of the rod or lateral portion E of the bail, which is engaged by the hook of the tilting lever, as shown. While in this locked position the rotation of the platen will not tilt the same because the pins g pull against the hooked ends of the arm G, thus preventing the tilting of the table until the catches are rocked away by the tilting of the entire bail. The forwardly-extending portions of the cradle are adapted to engage the ears D rising from the carriage to limit their movement, as indicated in Fig. 1.

H is a supplemental rack-bar or column-bar having the opening h,in which the pins 71/ are designed to be removably inserted for a wellknown purpose; but as there is no novelty claimed in the construction of this feature and its operation is well understood inthis art it is not thought necessary to dwell thereupon nor to illustrate the cooperatin g features on the carriage of the machine. The novelty in this instance resides in the means for facilitating the removal and application of the bar, so that one can be removed and another of like or dissimilar character inserted in its place, according to the character of the work to be done. This bar is provided at one end with the elongated slot h open at the end and through which passes the screw H, the head of which extends beyond the walls of the slot, the screw being held in the riser or lug A on the top of the frame of the machine.

H is a bolt, pin, or rod mounted for end Wise movement in the riser A beneath and parallel with the column-bar II. It has a head H upon its outer end, with a slot h for the reception of a screw-driver, and a head or enlargement h at its inner end, between the outer face of which and the inner face of the riser A is a spring H encircling the rod, pin, or bolt, as shown. The head h of this rod, pin, or bolt is of sufficient diameter to engage the end of the column-bar, as indicated in Fig. 12. The otherend of the bar II is formed with an elongated slot 71,, open at its outer end, and this end of the bar is reduced in thickness, forming the shoulder 717, against which is designed to engage the head 7L8 of the screw h", which passes through the slot into IOU a riser H on the top of the frame of the machine, the head of the said screw overlapping the walls of the slot. In practice the columnbar may be inserted or removed as follows: Supposing it to be in position, as indicated,

and it is desired to remove it, all that is nec-' essary to do is to move it in the direction of the arrow in Fig. 12 or toward the bolt II until the slotted end It is free of the head of the bolt H when by elevating said end the other end may be easily slid from beneath the head of this screw, it being understood that the spring H is compressed by the engagement of the end of the bar with the head 72. of the bolt, pin, or projection about which it is placed, and when the bar is removed the spring returns the bolt, pin, or rod to its normal position. To insert a bar,the slotted end 71 thereof is engaged with the shank of the screw I-I beneath the head thereof, and as the end of the bar H engages the headh of the bolt, pin, or rod H and pressure is exerted in the direction of the arrow in Fig. 12 the bar and the rod, pin, or bolt are moved outward, the spring being compressed until the slotted end h of the bar can be engaged with the shank of the screw H and then when pressure is removed from the bar the spring forces the same in the opposite direction, the shoulder h of the bar is engaged with the head of the screw H and the head of the rod, pin, or bolt H engaging the opposite end of the bar the latter is firmly held in position.

In orderthat the platen may be thrown into and held in position for either upper or lower case work, I have provided the mechanism seen in Figs. 3, 5, and 6, and to which attention is now called.

The front guide-rod B is mounted in the arms I, as seen in said views, and these arms are pivotally mounted on the transverse shaft or rod I, mounted in the hangers or brackets 2', depending from the under side of the top A of the machine-frame, as seen best in Fig. 5. To one of these arms I is secured by screws or analogous means 2" the plate or guide 1 which is offset near its ends to throw it away from the arm to provide sufficient space for the working of the lever I which is disposed between said guides and arm and is provided with a suitable handle, as seen in Fig. 3. From this lever projects the pin or screw or stud I which works in the slot 2' of the guide or plate I and to the outer face of this guide or plate is secured substantially mid-length of the slot, as at t the spring 1 which is curved, as shown in Fig. 6, and the ends of which are bent, as at 1' and extend into the line of the slot, and, as will be clearly understood from Fig. 3, as the lever I is moved up or down the pin or projection thereon will ride over the inclined portion of the spring near the end of the slot, and after it has passed the same it will be there held against accidental displacement by the oppositely-inclined portion of the end of the spring, so that while the lever will be held with sufficient security to prevent its accidental disengagement it can be, by sufficient pressure or force applied thereto, changed from the one position to the other. This may be done by hand as occasion may require, in which instance the rear end of the lever should be pivoted to some fixed support; but in this instance I have shown it so connected as to be operated also through the intervention of a key-lever and suitable connections. In Fig. 3, I is such lever, pivotally mounted, as at i, and to said lever, nearits rear end, is pivotally connected, as at t the rod or link I the upper end of which is connected, as at "i with the arm I of the bell-crank lever, to the arm I of which is pivotally connected, as at i", the rear end of the lever 1 The bellcrank lever is pivotally mounted, as at 1 on the lug or ear A projecting from the under face of the top A of the frame of the machine, as seen in Fig. 3, and around this pivot is a spring 1 the tendency of which is at all times to draw in the same directionthat is, that indicated by the arrow in Fig. 3. It will be readily seen that the front rod B can thus be shifted back and forth and changed from upper to lower case, or vice versa, by pressure upon the key-leverl, which, through the connecting-link and bell-crank lever, actuates the lever I which is held in either-of these positions by the spring 1 or this adjustment of the front rod can be brought about by the manipulation of the lever 1 by hand, as may be desired. I are lugs depending from the under side of the top of the frame of the machine, as seen in Fig. 3, and mounted in these lugs are the screws 1 one upon each side of the'upright I, by which the front rod is carried, and these screws are mounted for adjustment in the said ears or lugs, so that the limit of movement of the arm I can be regulated, so that the shift-rod will be thrown the required distance to bring the platen into proper position.

In Fig. 1 I have shown another form of mechanism for shifting the platen from upper to lower case, or vice versa. In this case the uprights or arms I are pivoted, as at I, and are shown in Fig. 1 as provided with a lateral arm J, having an openingj at its rear end to receive a link or other ligament by which it may be shifted to the shift-key 1, although this ligament is in this view omitted for the sake of clearness. J is a lever pivotally mounted, as at j, on the lateral arm J in line with its pivot I, and this lever has the for-,

wardly-extending portion J the upper face of which is cam-shaped, as shown at 7' and this operates against and in conjunction with the adjustable pin J extended downward through the top A of the frame of the machine. J 4 is a stop-pin on the upright I. It will thus be readily seen that pressure upon the lever J in the direction of the arrow indicated in Fig. 1 will cause the cam portion to move in the direction of the arrow thereon, which will force the arm J downward, as indicated by the arrow, and the upright I to the rear, as indicated by the arrow, and thus throw the platen rearward in position for use in connection with upper-case characters. Movement in the opposite direction brings the carriage and platen back to their normal position. Manipulation of the shift-key will bring about the same movements. The pin J serves to limit the movement of the portion J of the lever and stop it in the proper position.

In order to provide for the adjustment of the platen vertically in accordance with the number of sheets of paper on the platen, as in manifolding, I employ the mechanism seen in Figs. 4; and 13, in which K is a rod or bar arranged parallel with the front guide-rod and with the pivot 1 thereof and provided with a suitable handle 76, by which it may be manipulated. At its ends this rod or bar carries the upwardly-extending portions K, which are formed with the cam slots 76, through which the pivot-bar I of the uprights 1" passes, the depending lugs i being provided with the vertically-elongated slots 'L', as seen best in Fig. 13, and the vertical portions K being pivotally mounted, as at by screws or other means held in the depending lugs or brackets 2', and one of said pivots may be in the form of a thumb-screw, with its outer end milled or roughened, as seen at k in Fig. 4. It will readily be seen how by manipulation of the handle it on the cross bar or rod K the supports I and the front guide-rod B will be moved vertically in accordance with the thicknesses of paper upon the platen, the uprights and guide-rod being held in any adjusted position by reason of the cam-face of the slots is in the vertical portions K of the bar K.

L is the roll parallel with the platen and between which roll and platen the paper is designed to pass.

L is the bail in which the pintles Z of the roller are mounted, the end plates of the eradle having the slots d, in which these pintles work, as indicated in Fig. 19, and the end portions L of this bail have their inner faces inclined or cam'shaped, as shown, and bear against the pins L held in the end faces of the cradle, as indicated, and which form the fulcrum for the bail.

L are springs, one at each end of the platen, attached at one end to the end pieces platen with suflicient force to hold the paper and yet permitting of the movement of the roller away from the platen, as indicated in dotted lines in Fig. 19, as becomes necessary by the thicknesses of the paper employed.

M is a bar or rod extending from one side to the other of theplaten-frame and connected to the under face thereof in any suitable manner. On this rod are the guide-springs M,

arranged one at each end, being shown in Fig. 17 as held in position by the bolts and thumb-nuts m passing through parallel portions of the springs and detachably holding them to therod. These plates are bent to conform to the curvature of the platen, as seen in Fig. 17, and at a point substantially in line and just below the horizontal axial line of the platen. Each spring plate or guide is formed with the spring portions 'm separated therefrom by the slits m as seen best in Fig. 18, and thence bent at right angles to form the ears or lugs m, in which is held the pin M parallel with the axis of the platen, and mounted thereon is the arm M the lower end of which is bifurcated, as at m", and in the fork thereof is the shaft M, carrying a roller M, which works through a slot or opening m in the spring-guide or plate M, so as to bear upon the paper. The spring portions permit of the necessary yielding movements of the rollers and the arms by which they are carried, and the upper end of the arm being beveled or inclined the rolleris automatically held in any adjusted position.

The top A of the frame is provided with the slots A, extending at right angles to the guide-rod and having the slots a open at the ends of the frame and communicating with said slots A, as indicated in Fig. 2. The inner walls of the slots A are formed with notches a as indicated best in Fig. 2.

N is a bail. At the upper ends of this bail are carried the ribbon-guides N, provided upon their rear faces with the tapered rods or projections 71, which are adapted to ride in the notches (L7 in the top of the frame, these guides being provided with the rightangled portions 11., between which the ribbon is held, and formed also with the horizontal portions N (seen in Figs. 2 and 20) and provided with slots of usual form which receive the ribbon and serve to keep it fiat and prevent wrinkling and doubling thereof, this being a feature common in this class of de vices.

O are levers pivotally mounted, as at 0, on the sides of the bail, as seen most clearly in Fig. 14, and these levers have their lower free ends engaged in the forks p of the lever P, which lever is made springy and is disposed upon the under side of the horizontal portion of the bail underneath the machine. This lever is made springy, so that it may be maintained in two diiferent positions on riding over the coned portions 0 on the adjacent faces,the said lever I? being pivotally mounted at its center, as at 19, on the horizontal portion of the bail. The lower ends of the levers O are straddled by the bifurcations of the ends of the lever P, as shown, so that when one lever is moved in one direction the lever O on the opposite side of the bail will be si multaneously moved in the opposite direction. These levers 0 near their upper ends have the lugs 0 which engage the edge of the vertical portion of the bail, as seen in Fig. 20, to limit the movement of the lever on the bail. The extreme upper end of each lever is bent to form the horizontal arm 0 the free end of which is bent at right angles to' its length to form the lug or stop 0 Pivotally mounted on the outer faces of the vertical portions of the bail, near the upper ends thereof, as at q, are the levers Q, being so pivoted as to normally fall by gravity, and the rear ends thereof are connected by rod, link, or ligament Q with the bail Q which is the universal bail of the machine. Pivotally mounted, as at g, on these levers Q are the rocking levers Q the free ends of which carry pawls g adapted to ride on the crownratchets R, made apart of the end of the ribbon-spools R. The connections between the bail and the levers above described are made as near the center of the ribbon-spool bail as possible, so that the shifting of. the ribbonspool bail forward or backward will not affect the throw of the rocking lever. The levers 0 near their lower ends are formed with the offsets or curved bends 0 as indicated best in Figs. 1 and 13, so as to throw them out of the way of the pivots N of the bail N.

Q are levers pivoted at g on the upper ends of the side levers O and having a tooth or extension 1 and a right-angled or horizontal portion g as seen in Figs. 1 and 20. It will be understood that there is one of these levers Q at each side of the machine, and each is so disposed that its rightangled portion nearly touches the ribbon, so that when the obstruction or clasp T at each end of the ribbon or at a point joining the ends of two different ribbons comes in contact with the said rightangled portion or bend it lifts the whole lever up in the path of the lever Q, so that upon the next depression of a key-lever a key-lever Q will strike this right-angled portion, and the lever Q being pivoted on the side lever O of the ribbon-spool bail the automatic reverse of the ribbon-feed is accomplished.

The ribbon-spools are detachably mounted upon ears or rods S, supported in the arm S, extending from the vertical portion of the bail, as indicated, and the spool can be readily detached by merely pulling it off its pin or shaft after the ribbon-spool bail has been rocked as far as possible. The ribbon-spool may sometimes be formed with an inner flange R", as indicated in Fig. 1, adapting it to receive two different kinds or colors-of ribbon, so as to enable the operator to shift from one color or kind of ribbon to another almost instantly. The ribbon-spool may be provided wit-h a handle R at one end, as indicated also in Fig. 1, by which it may be revolved by hand when desired.

T is the ribbon. It is provided near each end with a projection, and in Figs. 10 and 11 this projection is shown at T in the form of a fastener having prongs 15, passed through the ribbon and into the cloth strip by which the end thereof is connected with the ribbonspool and there fastened. Fig. 10 mayv represent the end of the ribbon thus connected to the cloth, which is fastened to the spool, or it may represent the connection between two different kinds of ribbon-for instance, one a record and the other a copyingthe function of the class or projection being the same in both instances-namely, to secure the end of the ribbon to the adjacent part and serve also as a projection for operating the lever O and bringing about an automatic shift in the ribbon-feed.

At each depression of a key-lever the bail Q is depressed, as shown, and this through its connection with the lever Q causes the pawl Q2 to engage the crown-ratchet of the ribbon-spool and move it one tooth at each depression of a key-lever or rather at each return movement of a return-lever, the rotation of the spool being moved once at each manipulation of a key-lever. As the projection on the ribbon approaches the end of the pivoted lever Q it is lifted up in the way of the lever Q, so that the latter upon one side of the machine is thrown out of itsoperative relation with the crown-ratchet on the ribbonspool and that upon the other side is thrown into operative engagement with the crownratchet on the ribbon-spool upon its side, and automatic reverse of the ribbon-feed is thus brought about.

In Figs. 7 and 8 I have shown the crownratchet R as being fast upon the ribbon-spool shaft S and provided with the hub r, carrying one portion of a clutch, while the other portion r is carried by the hub of the ribbonspool, and on the lever O is an arm 0, bent at right angles to the length of the lever and again at right angles, forming the portion 0 which engages in an annular groove 0 in the hub of the spool, so that the vibratory movement of the lever P and the levers 0 will throw the clutch of the ribbon-spool upon one side of the machine into engagement and the other simultaneously out of engagement or operative relation, bringing about the same result. In this instance a spring-pawl T is mounted upon the arm S, as indicated in Fig. 8, to engage the crown-ratchet and prevent retrograde movement thereof and of the spool.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
