SPECIFICATION forming part of Letters Patent No. 578,121, dated March 2, 1897.
Application filed June 29, 1896.
T0 at whom it may concern.-
Be it known that I, CHARLES SPIRo, a citizen of the United States,r'esiding at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Type -Writing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to type-writing machines, having for its object, among others, to provide an improved machine of the Remington type which shall be simple in its construction, efficient in operation, durable, and not liable to derangement or injury to any of the parts. I construct the frame in sections that is, the front, back, and cap are made of separable partsso that in case of breakage the frame is not lost, but can be readily repaired by replacing the broken part. I provide a simple construction and mechanism for inverting or tilting the platen by means of a key, whereby the work may be readily inspected, the platen being mounted to automatically return to its normal position when pressure upon the key is removed and to be automatically locked in such normal position. Novel mechanism is provided for thus looking the parts. The carriage is detachably mounted for easy removal for cleaning. I dispense With a sliding frame for shifting from lower to upper case and in lieu thereof provide simple mechanism, the carriage having pivotal connection with its roller frame, whereby the latter is rocked upon its guiderod as the carriage is shifted back and forth to change from upper to lower case, or vice versa. I provide an improved keyboard-lock for preventing printing of letters one upon another after the end of a line or a predetermined point has been reached, the said lock being adjustable to vary the point of locking and the latter released by the carriage-shift key. The platen and line-feed are removabl y mounted to permit of the substitution of others when desired. The linefeed pawl is mounted to. bethrown out of mesh automatically to permit of back rotation of the platen, a roller abutment for the feed dogs or pawls being provided. I further provide an improved simple and accurate paper-feed. Furthermore, I provide a more durable and sim- Serial No. 554,474. (N0 model.)
ple hanger for the type-bars and provide for adjustment thereof in case of wear. The mechanism for the automatic reversal of the ribbon and for an automatic lateral shift at each reversal thereof is of simple and novel construction. A simple means is provided for placing the parts in position for writing upper or lower case characters solely. The tension for the keyboard is simplified and conveniently arranged. I have arranged for the easy removal of the ribbon-spools and for the placing of the ribbon in position.
I aim at various other improvements in details of construction and in the arrangement of the parts, all of which will be more specifically called to attention as the description proceeds.
Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in Which Figure l is a top plan of my improved typewriting machine with parts broken away to better disclose other features. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1. Fig. 3 is an end elevation of the carriage, showing the manner of removably locking the platen in position.

Like letters of reference indicate like parts throughout the several views.
Such elements of a type-writing machine as are not herein specifically described or referred to may be of any well-known or approved form of construction and mounted for operation in the usual manner. Only such parts are shown as are necessary to a proper understanding of the features constituting the present invention.
Referring now to the details of the drawin gs by letter, A designates the frame, which comprises the front A, the body portion A and the rear portion A these three parts being cast or formed separately and nicely fitted together and detachably united in any suitable manner, as, for instance, by screws a, whereby when either part becomes broken or damaged to such an extent as to require its replacement by a new part the said part may be replaced without loss or discarding of the remainder of the frame. The bod y portion of this frame is formed with the standards or posts A, adapted to receive suitable yielding pads or feet a in the usual manner, and adapted also to support the top A which may be fixed thereon in any suitable manner, as, for instance, byscrews a passed through the top and entering the upper ends of the posts. Such securing means are shown in Figs. 1 and 4. This top is formed at opposite ends with the slots A, extending in the direction of the same from front to rear, said slots communicating with the open-ended slot to, eX- tending at right angles thereto, the said slots A being for the reception and guidance of the ribbon A and the slots a provide for the introduction of the ribbon into the slots A by the placing of said ribbon parallel with -the walls of the slots 0 and then bringing it parallel with the walls of the slots A, as will be readily understood from inspection of Fig. 4.
The key-levers B are of known construction and mounted in the usual manner, 13
being the back transverse rod upon which from sheet metal and comprises the base portion and the parallel side bars I), in which are supported the journals for the type-bars.
These journals B are arranged, as seen best in Fig. 12, at angles to each other, so that they practically cross, as indicated in said Fig. 12, the said journals of course being upon different vertical planes, as illustrated in Fig. 13, and each hanger supporting two journals and consequently two type-bars. The ends of the journals are cone-shaped, as seen at b in Fig. 12, the one end being supported in a like bearing in one of the said bars I) of the hanger, while the other extends into and has a similar bearing in a nut B, which nut is engaged in a screw-threaded opening in the side bar I) of the hanger, whereby ready adj ustment for wear is provided. The type-bar is provided with a sleeve or boss 13, which receives the journal and upon which it is rigidly secured. The tail of the type-bar isperforated, as shown at b for the reception of the ligament which connects the same with the key-lever, as usual. The placing of the journals at different angles, as shown, provides for the accommodation of the two typebars on the same hanger and economizes space. The nuts upon the ends of the journals are arranged at opposite ends, as shown, so as to be more readily accessible for ad justment when necessary. The hanger is secu red in position upon the ring A of the top A by means of a screw 1), passed through an opening Z1 in the horizontal portion of the hanger, as seen best in Fig. 1.
I deem it expedient to next describe the ribbon-feed and the mechanism for causing the automatic reversal thereof at each end, as well as a lateral shift upon each automatic reversal, and for this purpose special attention is directed to Figs. 6, '7, 9, 11, and 14, in which the top A is shown as provided at each end with the depending arms or lugs O, in which are journaled the spool-shafts O, as seen best in Figs. 6 and 7, and which spoolshafts carry at one end a beveled gear C adapted to mesh with the smaller beveled gears C on the transverse shaft C, arranged at the rear of the machine in suitable bearings or lugs C depending from the top A of the machine, as seen best in Fig. 14, this latter shaft C being designed to be moved lengthwise in its bearings by mechanism hereinafter described, the ribbon being designed to be fed along automatically at each depression of the key-lever in the usual manner.
The main portion of the frame is formed upon opposite sides thereof with the lugs A", as seen best in Figs. 6, 7, and 14, in which lugs are journaled to rock the shafts D, one upon each side of the machine, as seen in Fig. 14, these shafts being designed to be held in the lugs in any suitable manner, as, for instance, by the screw shown in Fig. 14, although this is an unessential feature of thee-onstruction. Each of these shafts D carries uprights D, which in Figs. 9 and 14 are shown as curved, and their upper ends are connected by the shaft D on each of which are mounted to slide lengthwise thereof the rollers D which are lines in Fig. 7.
adapted to lie between the heads or flanges-e of the ribbon-spools E, as indicated by dotted These rollers are connected to move together and in the groove 6. Between said rollers is mounted to work the end or head 6 of the arm E which is pivoted at its lower end, as shown at E, to the base or frame of the machine, as seen in Figs. 6 and 7. These rollers are adapted to bear yieldingly against the ribbon wound upon the ribbon-spool, and as the ribbon accumulates thereon the said rollers and the rocking frame by which they are carried are gradually moved inward toward the center of the machine, as will be readily understood. Each of these rocking frames carries a spring-arm E (seen in Figs. 6, 7, 9, and 14,) the upper end of which is forked to embrace the shaft 0 and adapted to engage a collar e thereon, as seen best in Fig. 14. The-side bar or upright of the rocking frame is provided with an extension 61, as seen best in Fig. 9, from which projects a lateral pin 61', as seen in Figs. 9 and 14, against which the forked end of the spring-arm engages, as seen in Fig. 14. Pro-- jecting laterally from a depending lug E on the top A of the machine is a projection or screw 6 on which is pivotally mounted an arm E, as seen in Figs. 6 and 14. This arm is adapted to rest upon the collars e on the shaft 0 alternately-that is, when the said arm on one side of the machine is riding upon its collar the arm upon the other side is engaging against the face of the collar upon the opposite side, as seen best in Fig. 14.
In operation, as the ribbon is wound upon the one spool and unwound from the other, as it accumulates upon the former the rollers D of the spool which is receiving the ribbon will be gradually forced away therefrom, while the rollers upon the other side will gradually move outward as the ribbon on the said spool is unwound. Now as the rocking frame carrying said rollers is moved inward toward the center of the machine the tapered or beveled end of the extension cl of one of the uprights of the rocking frame is gradually engaged under the free end of the arm E and the latter is lifted from its engagement with the i11- ner face of its collar 6 and in the continued movement of the rocking frame the said arm 11 is moved up over the said collar, as indicated at the left of Fig. 14, in which view the ribbon-spool upon the left is receiving the ribbon and is nearly full, while from that upon the right the ribbon is being unwound. As seen in said Fig. 14, the ribbon has just been reversed, the shaft C having been moved to the right so its beveled pinion would mesh with the beveled pinion O on the shaft O at the right of the machine in said Fig. 14.
As soon as the arm is raised clear of the collar 6 the spring-arm E comes into play and forces the shaft 0 endwise against the action of the spring E at the opposite side of the machine, and shouldthe pinion C for any reason fail to immediately engage with its pinion C the continued movement of the rocking frame will cause its spring-arm E to force the said pinion into engagement with its mate. It will of course be readily understood that the same operation occurs when the ribbon is unwound from the spool on the left and is wound upon that on the right in Fig. 14.
In order to provide an automatic lateral shiftof the ribbon at each reversal thereof, as above described, so that the entire surface of the ribbon may be brought into operative position and thus its entire surface utilized, I have provided the means illustrated more fully in Figs. 6, 7, 9, and 11, to which special attention is now called. The arms E the upper ends of which engage in the grooves of the pressure-rollers D are connected by or formed integral with the connecting portion E, as seen best in Figs. 9 and 14, and projecting laterally from one of these arms or uprights E is the yoke E between the bif urcations of which is mounted to work a cam E (shown best in Fig. 7,) this cam being fast upon a shaft E", vertically disposed and mounted for rotation ina suitable bearing on the frame. The upper end of this shaft is formed with or carries a ratchet-wheel Dflwhich, as seen in Figs. 7 and 9, is mounted to revolve in a horizontal plane, and with this ratchet engages a pawl Diwhich is pivotally mounted upon a rod D, which connects the uprights D of the rocking frame at a point between their upper and lower ends, as seen best in Figs. 7 and 9. The operation of this part of the invention will be readily understood and is as follows:
At each reversal of the ribbon as it nears its end the rocking frame carrying the pressure-spools is moved sufficiently to cause the pawl D to move the ratchet D one tooth. This movement of the ratchet causes the shaft F. to be moved so that movement of the cam thereon engaging between the bifurcations of the yoke on the arm E will move the latter laterally'sufiiciently to move the ribbon-spools laterally on their shafts, so as to bring a different surface of the ribbon into operative position. The ribbon-spools, as will be readily understood, are mounted for movement lengthwise of their shaft and should move by the engagement of the pressure-rollers D the latter engaging the flanges or heads of the ribbon-spools between which they are mounted to work. The ends of the ribbon-spool shafts are free, so that the spools may be readily placed thereon or removed when it is desired to replace them. by a new ribbon and spool. It will thus be seen that not only is the direction of the movement of the ribbon automatically reversed at each end of its movement, but at each such reversal the ribbon is shifted laterally, so as to bring a different lateral surface thereof into operative position.
The carriage is given the usual step-by-step feed in the ordinary way, the feed-pawls F F (seen in Fig. 4) being mounted on the block F and in order to provide a firm abutment for said block to prevent injury thereto and to the pawls by the movement of the carriage I provide the block F upon which is mounted the friction-roller F on a suitable vertical pivot, as seen in Fig. 4, by which means I not only provide a firm abutment for the block carrying the feed-pawls, but materially reduce the friction, the said friction-roller being so mounted as to be engaged by the block F in its reciprocatory movements. The ordinary step-by-step feed-rack F", with which the pawls F F engage, is shown as thrown back in Fig. 4 and is shown in operative position in Fig. 1. It is provided with ears f sleeved upon the guide-rod F.
The rear guide-rod F is mounted in lugs a on the rear portion of the top of the machine, as seen in Figs. 6 and '7. The front guide-rod G is secured to and mounted upon the arms G, secured to the rocking shaft G which is mounted in suitable lugs or supports depending from the under side of the top A of the machine near the front, and this rod and the uprights are designed to be moved backward and forward to shift from upper to lower case, or vice versa, by simple and novel means illustrated clearly in Fig. 7, in which a finger-lever G is shown which is pivoted upon the shaft G in any suitable manner, and this lever is provided with a cutaway portion 9 and shoulders g7 g all as clearly shown in Fig. 7, and the upright or arm G upon this side of the machineis provided with a projecting pin G, designed to be engaged by either of the said shoulders to hold the front shift-rod in either its backward or forward position. A spring G is employed, one end of which is connected in any suitable manner to some fixed part, as the top of the machine, and its other end engaging a stud g 011 the lever G as clearly shown in Fig. 7. The arm G upon this side of the machine is provided with a rearwardly-extending arm G, the inner end of which is connected by a link or ligament G with a shift-key lever G, as indicated by dotted lines in Fig. '7, whereby the carriage may be shifted to upper or lower case by the manipulation of said key.
H, Figs. 1 and 4C, is the margin-regulator rack-bar, suit-ably mounted upon the top of the machine an d carrying at its center the index-finger or pointer II. 11 is a stop slidingly mounted upon this rack-bar and provided with a spring-actuated pawl H de signed to engage with the teeth of the rack, this stop being adjustable to regulate the margin, the carriage being provided with a depending part or abutment to engage therewith, as will be readily understood. Slidingly mounted upon this rack-bar upon the opposite side of the center is a stop H having a spring-actuated pawl H for engagement with the teeth of the rack and designed to be adj ustable to cause the bell to ring at any predetermined point, the stop H for engagement therewith being pivotally mounted, as at h, on the platen-carriage and designed to engage the bell-hammer H pivotally mounted upon the carriage and designed to sound the bell H in the usual way. The stops H H, either or both, may be arranged to be manipulated from the front of the front guiderod in any suitable manner so that they may be adjusted without lifting the carriage.
In Fig. 4 I have shown the block or stop H as provided with an arm h, while the pawl ll is provided with an extension or arm 76*, by the movement of which in the direction of the arrow in said Fig. 4c the pawl will be disengaged from the rack, when the block or stop may be moved in either direction by the arm h, and when pressure is removed from the arm h the spring of the pawl forces the latter into contact or engagement with the rack, and thus locks the block or stop in its adjusted position.
I is the j ump-feed or column regulator rackbar, suitably mounted at the rear of the machine, as seen best in Fig. 4, and provided with the removable pin i, of usual construction, adapted to be inserted into any one of the holes in the rack to regulate the space between the columns, while upon the carriage is pivotally mounted an arm or lover I, pivoted at t" and adapted to be thrown down into the path of the said pin, so as to engage the sam e when tabulated work is to be performed.
I is an arm projecting from the usual stepby-step feed-rack F and adapted to be engaged by the arm 1, pivotally mounted at the left-hand side of the carriage and its front end terminating in a finger or thumb piece 1 as shown best in Fig. 1, by pressure upon which the rear end of the arm I is brought against the under side of the arm I and the rack-bar F lifted from engagement with the feed-pawls, so that the carriage may be moved in either direction, as may be desired.
J is the platen, of usual construction, and J is the roll between which and the platen the paper is designed to pass. J is the scale holding the roll up by means of the springs J connected as shown in Fig. 10, so that the platen and roll are kept in contact for feeding the paper, the scale being arranged as shown, so as to practically cover the roll J, as shown, the scale and the roll being both mounted in the end platesj of the frame, said end plates being connected by the back connecting-bar], as seen in Figs. 16 and 17.
J is a bar or rod which extends from one side to the other of the platen-fra1ne and is detachably connected to the end plates j in any suitable manner, as seen in Fig. 16. On this red are the guide-springs J one at each end, which maybe arranged as seen in Fig. 16, where they are shown as attached at one end to the rod J 4 and at the other end to the scale J the said guide-springsj ust barely touching the platen on the line of printing; or these springs may be arranged as shown in Figs. 1 and 2, where they are shown as free at the end be- IIO neath the platen, while the other end is attached to the rod J 4 andis rendered adjustable by means of a screw j passed through the said rod or bearing upon the spring between its front bend and the platen, as clearlyshown in Fig. 2. When paper is introduced between the platen and the roller, the scale J is depressed to allow of the free passage of the pa per between the platen and the guide-sprin gs J ,and when the paper has been fed forward,so that the same is no longer in contact with the roll J, then the tension on the scale J 2 presses the guide-springs J up against the paper and holds it there to allow of printing to the very lower edge of the paper, whereby the last line of printing on the paper will be straight and parallel withthe precedinglines. On the rod .1, I mount frictionally the clamp or sliding piece J which is preferably blanked out and formed with earsj to receive the pin as seen in Figs. 16 and 17. On this pin is pivoted the curved spring-piece J which is also provided with ears j for this purpose, as seen best in Fig. 16, and on the concave surface of this piece J I mount the curved piece J so that it may be slid along beneath the piece J and fastened either at the extreme top, as
shown in the drawings, or at a point where the small roll 9' carried by the lower end of the piece J may be brought into contact with the roll J. This sliding movement may be provided for in any suitable manner, in this instance being shown as a thumb-nutj secured in the under piece J and passing through coincident slots j in the curved pieces J and J as clearly shown in Fig. 16.
The piece J 7 is tensioned by the spring J as seen best in Fig. 16, which is arranged between the ears thereof around the pin 3' so that the roll 7' which is loosely pivoted in the ears formed at the lower end of the piece J may always rest in contact with the platen, as seen in Fig. 17. Now when the paper is introduced the guide-springs J 5 carry the paper along until the top edge nearly reaches the roll j when the pressure upon the thumbnut j tilts the roll 3' away from the platen and allows the insertion underneath of the paper without lifting up of the carriage, and after the lower edge of the paper has left the roll J then the roll 9' acts as the feed to allow of writing to the very bottom edge of the paper, as will be readily understood.
When it is desired to write upon envelops, the sliding piece J is slid along upon the rod J where it will allow'the envelop to be'taken to allow of writing as much as may be desired on the envelop. After such adjustment the piece J 8 is slid down, so that the rolls 7' and J are in contact, when said piece is fastened in such position by the thumb-nut. It will thus be seen that the envelop need only be introduced into the carriageand fed along writing. The shaft or journals j" of the platen are passed through and rotatably mounted in the end pieces j of the platen-frame, and upon one end thereof is secured the bell H the edge of which is milled, as shown in Fig. 1, and by which the platen may be rotated by hand, as may be desired. The extended ends of the platen shaft or journals are removably mounted in the carriage K, and in Figs. 1 and 3 I have shown one means of thus detachably holding the said platen journals. In this form the carriage is formed with the lugs k, undercut or shoulders, as seen in Fig. 3,while upon lugs k, to the rear thereof, are detachably pivotally mounted, as by the screws 10 the arms K extending parallel with the end bars of the carriage, their forward ends being provided with depressions or sockets K as shown best in Fig. 3, to receive the journals of the platen, the said arms being extended rearward of their pivots and downwardly to engage stops k on the carriage. Between the pivot and the journal-receiving socket there is arranged a spring K upon which the said arm rests, and this spring is arranged in a socket 70 formed on the carriage K, as seen in Fig. 3. By depressing the arms K into position indicated in full lines in Fig. 3 the platen-journals may be readily removed. They may be readily inserted by placing them upon the front ends of the arms K, when by pressure thereon the journals can be easily forced into position, and when'once in place the springs force the arms up and lock the platen against accidental displacement, but permitting of its easy rotation. The platen-carriage K is provided at its front side with the rollers K adapted to run upon the front rod G, as shown. The carriage K has extending from its rear portion the rearwardly-extending perforated ears K, as clearly shown in Fig. 1,which are detachably secured to so as to move with the carrier-frame L, which consists of the boxes or frames L, in which are journaled the axes Z of the rollers L which ride upon the rear guide rOd E the said ears being detachably secured to the boxes, in this instance by the thumb-screws l, as seen best in Fig. 1.
' The boxes L are formed with ears or lugs Z perforated to receive and which ride upon the rear guide-rod F as seen best in Fig. 4, where the carriage and platen are removed and the step-by-step feed rack-bar F and the carrier-frame are thrown back in order to better disclose other parts.
- The means employed forconnecting the ears of the frame K with the boxes L permit of the pivotal movement of the carrier-frame L, which movement is limited in its downward direction by means of the pins 1 projecting from the said frames or boxes L and engaging upon the lugs l of the rear portion of the carriage K, as clearly illustrated in Fig. 1.
By removal of the thumb-screw Z the frame K with all its accessories can be removed for the purpose of cleaning or otherwise. In shifting the carriage to change from upper to lower case, or vice versa, the carriage K and its ac cessories moves in a horizontal plane, while the carrier-frame L and its boxes and rollers rocks upon the rear rod F turning upon the screws Z as a pivot. To further guide the carriage in its back-and-forth movements when it is shifted for upper or lower case letters, I provide the bifurcated guide-arm L secured to the under side of the rear portion of said carriage, loosely embracing a guide-screw or other means L secured to the upper face of the ordinary step-bystep feed rack F as shown best in Fig. 1.
Fast upon the platen shaft or journal is the ratchet M, (seen best in Figs. 1 and 5,) and the platen is designed to be rotated, when required, by means of the lever M, pivoted at m on a lug or riser on the carriage K, the said lever having an extension m beyond its pivot and beyond the journal of the platen, as seen in Fig. 5, and to the end thereof is pivoted, as at 971 the pawl M the upper end of which is hooked, as seen at m in Fig. 5, and extended into the plane of the ratchet-wheel, so that by manipulation of the lever M the ratchet-wheel may be turned one or more teeth and the platen revolved. A spring m connects at one end with the pawl and at the other end fastened around the pivot of the same, as seen in Fig. 5. The outer face of the pawl is provided with a cam portion m adapted to engage a pin or projection m on the carriage K, which serves to normally hold the tooth end of the pawl out of engagement with the ratchet, but when the lever M is moved on its pivot the said cam moves under an engagement with said pin, thereby bringing the tooth end of the pawl into engagement with the ratchet when the further movement of the lever M rotates the platen. Then pressure is removed from the lever M, the parts return to their normal position, the cam portion engaging under the pin m and throwing the tooth end of the ratchet away from and out of engagement with the ratchet.
The limit of movement of the platen is regulated by the readable line-space-regulating device seen best in Figs. l and 10, in which the lever M is shown as provided with an upwardly-projeeting bearing or standard M which is bored from front to rear, and in this bore is arranged a rotatable regulator M which is provided with a circumferential groove M in which works the pin or screw M (see Fig. 10,) which permits of rotation of the regulator M but holds it against endwise movement. The inner end of this regulator is provided with a series of notches m in steps, as seen in Fig. 5, the other end of the regulatorbeing provided with a collar and shoulder m bearing against the face of the extension M and provided with a series of slight depressions M into any one of which is designed to engage the pin M the upper end of which is rounded or pointed, so as to readily slip into the depression, the said pin being mounted for vertical movement in a socket in the extension M being seated upon a spring M located in said socket, which serves to normally keep the pin uppermost, but permitting of depression thereof when the regulator is turned. The outer end of this regulator is polygonal inform, as seen in Fig. 10, and upon its faces are designating-characters, as seen in Fig. 10. By rotation of this regulator the desired notch in its inner end may be brought into position to be actuated by the engaging means therefor, which will soon be described, and by means of which the platen is permitted to be turned one, two, or three or more teeth bya single manipulation of the lever M, the pin M readily seeking its depression and holding the regulator against farther movement accidentally. The inner end of this regulator is designed to be engaged by the lever N, pivoted at 'n on one of the end plates j of the platen-carriage, being provided with a spring 72, as seen in Fig. 5, and having a curved extension N, in the free end of which is journaled a roller N arranged in vertical line with and adapted to bear against the ratchet M to prevent retrogade movement thereof accidentally, butpermitting, through the resiliency of its springlevers, rotation of the platen by hand when desired. The vertical face of this lever N is arranged in the path of and designed to be engaged by the notch or'notches of the regulator as the lever M is manipulated to revolve the platen. The platen and its carrier, together with the ratchet, and the lever N, with its roller and spring, are all removable bodily from the carriage, when desired, by the means heretofore described and shown in Fig. 3.
O is the paper-table. It is detachably conn ected with the end plates j of the platen carrier or frame by means of the pins 0 at the ends thereof, which are detachably engaged in openings 0 in the rear ends of the said end pieces j, as seen in Figs. 1 and 2. The rear edge of the paper table is engaged detachably in the free ends of the arms 0, which are pivotal] y mounted on a shaft P, mounted in the curved plates P, which are fast upon said shaft, the shaft and plates being designed to move pivotally, the inner faces of the curved plates P being provided with pins 19, between which the arms 0 work, whereby the latter have a limited play or movement of themselves independent of their movement of the curved plates. The plates P are further connected by the rod P with which rod is designed to be detachably engaged by the upper hooked end 29 of the arm P the lower end of which is pivotally connected, as at 19 with the lugs 19*, Fig. 15, extending upward from the rear cross-rod P of the bail P, which is detachably mounted at its forward end upon the rod P suitably supported in the frame A near the front, as seen best in Fig. 8. This bail is shown in Fig. 15 as provided with bosses or analogous devices 19 sleeved upon the rod P and held in position by the set-screws 19, wherebythe same may be readily removed when desired, the rod P being also removably supported in its bearings on the frame. This bail is connected at one end with a special key-lever P by means of the ligament or link 13 which is pivotally connected at both ends, the said special key-lever P extending to the front of the machine and by the manipulation of which the platen is tilted so that the writing may be readily inspected. In Fig. 8 the parts are shown in the position which they occupy when the said le- Ver is depressed and the platen has been tilted. In order to lock the parts in their normal position during the process of writing, I extend one of the pins 0 on the end of the paper-table, as seen in Fig. 5, with which is designed to engage the hooked end q of the lever Q, pivoted at g on the end of the carriage K, and at its free end carrying a roller Q, with which the cam portion P of the curved plate P. at that end is designed to engage when the lever P is depressed to tilt the platen, thus throwing the hooked end q of the lever Q out of engagement with the extended end of the pin 0 and allowing the platen to be tilted and the parts to assume the position in which they are shown in Fig. 8. A spring (1 is provided upon this lever to normally hold it in engagement with the said pin, as
seen in Fig. 5, and a spring Q is provided,
as shown in Fig. 8, acting upon the shaft P to aid in returning the platen and paper-table v to their normal position as soon as pressure is relieved from the lever P The curved plate P at the left-hand end of the machine is provided with a finger-lever P by means of which the platen may be tilted by hand when desired without manipulation of the lever P7.
In order to lock the keys against actuation when the end of a line or a predetermined point is reached, and thus prevent the writing of one letter upon another, I attach to'the universal bail R, which of course is actuated by the space-bar R as well as at the depression of each key-lever, a 1*odR vertically disposed and adj ustably connected with said universal bail, as seen in Fig. 7, and the upper end of this rod is adjustably and detachably connected with a headed projection R which is adapted to work easily in an opening in the top A of the machine, as shown, while pivoted at the rear of the machine, as at s, is an arm S of such a thickness as to be readily forced under the head of the part R when the latter is in its uppermost position, as seen in Fig. 7, a spring S being provided, one end being attached to the said arm and the other end free and working against a pin 5 on the top A of the frame, as seen best in Fig. 4. The arm S is pivoted upon its upper face near its free end with a pin 5 (shown in Figs. 4 and 7,) with which pin is designed to engage the forked arm T, depending from the rear of the carriage K, and, as shown in Figs. 1 and 8, adjustably mounted upon a rod or bar T,
carried upon the said carriage K and designed to be adjusted to bring the said forked arm so that it will engage with the pin of the arm S at a predetermined point in the movement of the carriage, and as said arm engages the pin it moves the arm S with it until the latter is moved under the head of the pin or part R as seen in Fig. '7, and thus locking the carriage against movement and the key-levers against depression sufficient to force the type against the platen. When it is desired to release the arm S, the shift-lever is depressed and as the carriage is moved rearward the opening in the forked arm is brought coincident with the pin 8 on the arm S and when the same becomes coincident the spring S forces the arm S in the direction of the arrow in Fig. 4, consequently releasing it from engagement with the head of the part R The spring for propelling the carriage forward is of well-known construction, as is the rying the dogs or pawls F by a spring U, as
seen in Fig. 6. Adjustment of this screw regulates the tension of the dogs. This means is placed in amost convenient position and is easy of manipulation.
