TYPE-WRITING MACHINE.

SPECIIFICATIONV forming part of Letters Patent No. 430,416, dated J' une 1'7, 1890. Application filed January 5, 1887. i Serial No. 223,471. (No model.)

To all whom it may concern:

Be it known that I, XVALTEE J. BARRON, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a speciiication, reference being had therein to the accompanying drawings.

1c. The Iobject of my improvement is, iirsi, to permit the platen to be raised independently of the paper-carriage when it is desirable to look at the writing produced; second, to have the bearings of the platen retained by r 5 adjustable springs against a rigidly-supported feed-roll, and thereby permit manifolding to be as evenly printed as upon a single sheet; third, to retain the line-space lever immovable while raising the platen; fourth, to pivot zo the front scale so that it can be pushed against the platen and take the place of two scales; fifth, to provide the type-bar with an intermediate lever to throw it up and a spring to throw it down; sixth, to provide means for retaining the key-levers connected with the frame at three points and other means hereinafter described, and specifically set forth in the claims.

In said drawings, Figure 1 is a portion of a type-writing machine having the parts constructed and combined in accordance with my invention. Fig. 2 is an end View of the platen, its support, the paper-feed mechanism, and its carriage. Fig. 3 is a transverse vertical section of these parts, taken about the middle of their length. Fig. l is a vertical section of one of the type-bars, its intermediate operating-lever, and spring which throws the type-bar down. Fig. 5 is a top view of the main portion of a type-writing machine, showing the improvements attached thereto. Fig. 6 is a perspective view of one of the indicator-scales. Fig. 7 is a perspective view of the ribbon-feeding mechanism. Fig. 8 is a front view of the main portion of a type-writing machine having my improvements. Fig. 9 is a perspective View of one of the key-levers. Fig. 10 is a front view, upon a smaller scale, of the platen and its 5o carrying-frame turned up to show the under side thereof and its paper-guides.

present case by preventing this carriage from being lifted. This is accomplished by means of a strap h2, secu red to the front rail of the fcarriage and having its hooked end passmg ,under the front guide-railAZ.

To permit the writing to be seen, as shown 7o `by dotted lines in Fig. l, the platen C is carried by a rectangular frame c, having as a part .Y of its rear portion a rod c2, that is retained in U-shaped bearings c3, projecting upward from the yoke b3 of the carriage B. The 75 bearings c3 are purposely unprovided with caps, so that the frame c can be easily removed from the carriageB by slightly lifting said frame while drawing it forward; but, to prevent the accidental disconnection of the 8o parts, the frame c is retained upon its bearings by a bent spring b4, having its upper end resting upon the pivot-rod c2 and the other end secured to the rear rail of the carriage.

To permit the platen to be lifted independently of the paper-feed mechanism or frame c to insert the paper, if desired, said platen is pivoted upon two arms O2, that have their rear ends pivoted upon the rod c2 of the rect*A angular frame above described. Under the 9o platen the feed-roll (l is supported upon arms D,\that are rigid in place of yielding, as heretofore, and the pressure upon the bearings of the platen, and said pressure on the platen holds the paper tightly against the feed-roll. The object of this construction is to obviate a defect found in many type-writing machines when manifolding-that is, the letters are thrown out of alignment when :more than one sheet of paper is used. lVith the present construction the relation of the type to the paper is never changed, even if twenty sheets are IOO inserted, as the platen rises from the feed-roll instead of the feed-roll receding from the platen. The arms C2,v carrying the platen, are retained by springs cl2, retained adjustably secured to the frame c by means of screws d3 passing through them about halt-way of their length. One end of said springs bears upon the frame c,while the opposite end bears upon arms c4, projecting laterally from the frame c2. These springs hold the platen against the feed-roll and the papeifeed is regulated by them. If the paper happens to feed crookedly, by tightening or loosening one of the springs the diiiiculty is remedied.

To regulate the insertion of the paper in the machine and make corrections, a gage is used. It consists of a strip E,having numbered subdivisions. To this strip are secured jointed arms at each end, as shown in Fig. 6. One end of the arms is pivoted to a bearing c, to be secured to the front rail A2. This gage cau be pushed against the platen and can take the place of the two scales or gages, heretofore used.

To correct an error, it is only necessary to place the carriage in a position where the pointer will indicate the first number or iigure on the gage, then swing the platen up, swing the gage up against the paper, note the point on the gage where the type is to be struck, drop both gage and platen to their normal position, set pointer on carriage to the desired place on gage, and strike the key. The same object may be accomplished by fastening the strip E to a single arm, as shown in Figs. l and 5. This arm has a tubular eye at its lower end and can be moved adj ustably upon a rod e, that is secured at each end to the front rail A2.

To correct an error, it is only necessary to swing the scale against the paper, note at what point the error occurred, throw the scale back, as shown in Figs. l and 5, and set the pointeron the front of the carriage to the place on the scale on the front rail corresponding to the point the arrow was indicated on the scale E, and then strike the correct letter.

In this machine the ribbon Fmoves with the carriage. Its spools f and f are mounted obliquely on the ends of said carriage. They are detachable, their journals f2 being retained by caps f2, secured to the carriage by thumb-screws f4, so that when the ribbon is all wound on the right-hand spool f it is only necessary -to reverse them and place the full spool on the left end of the carriage and the empty spool on the right end. Every time a line is to be begun the spool on the right end is revolved by the spring-pawl f5, pivoted to an arm F5, having one end pivot-ed to the carriage B, and the arm F5 at the other end is supported by a spring FG and said arm pressed upon by a finger G, secured to the line-space lever G, and to the latter is secured the pawl G2, the hooked end of which is in engagement with the ratchet-wheel of the platen; but the pawl f5 is in position to engage with the ratchet-.wheel f6 upon the shaft ofthe spool f. By this means enough ribbon is taken up to present a fresh place for the Vtype to strike on the nextline written. The ribbon runs diagonally over the types often, as it is drawn forward only one-fourth of an inch each time the line is changed. Upon the journal of the spool fa coiled spring f7 presses against a collar upon said Journal to retain the ribbon under tension. The ratchet-wheel fS has a retaining-pawl f8, and under each spool there is a pendent arm f, set horizontally to retain the ribbon at a properdistance under the platen. The linespace lever G is pivoted to a standard B2, secured upon the carriage B. It is not raised with the platen; but it carries a spring finger or pawl G2, the hooked end ot' which is in engagement with the bottom of the cogwheel C at the end of said platen. The line-gage lever g is pivoted to the standard B2, and can be set with its handle in a Vertical or in a horizontal position to make a narrow or a wide space, respectively, between the lines. Each type-bar hanger h is secured to the platform A by a screw h', under the head of which is placed a washer that may be in the form of a continuous circle extending over all the hangers. To the inner end of the hanger is pivoted, at h2, one end of the type-bar H, the type-bearing end of which is automatically thrown down by a flat metal spring h3, secured to the top of the hanger and having its downwardly-bent end pressing upon the top of the type-bar in front of its pivot. The connecting-rod i of the key-lever I is not pivoted, as usual, to the tail end of the type-bar, but is pivoted to the tail end of an intermediate bell-crank lever 2, that is pivoted at Q13 to the hanger h at a point under the spring h3, and said lever t2 has at its lower end Van arm if, that bears against the under side of the type-bar and lifts it under theimpulse of the finger-key or key-lever.

It has been necessary in many type-writing machines heretofore constructedto have the type-bars work on any easy pivot, so that thel bar could drop back to place after a key was struck. This pivot will wear and become so loose that the type will not always strike in the same place. By the above-described construction a close bearing can be used, as the spring 71.3 will cause the type-bar to return to its normal position; but even it' the pivot is loose when the type-bar is down it will be found close-fitting when said bar is up, as the spring bears against its top in close proximity to its pivot, and the bearing is nearly immovable at the moment the type strikes the paper, and it will not fail to strike it in the same spot.

To permit the key-levers I to be easily disconnected from the machine to make repairs, the reed-bar commonly used on the back part of the machine can be dispensed with. In the present instance each key-lever has inserted in or passed through its rear end a and will not require changing or reversing IOC IIO

spring-Wire I2, that is made to pass under a cross-bar A4 and over a rear bar A5 ot' the frame of the machine. The under edge of the bar 'A4 and the upper edge of the bar A5 are provided with serrations to retain the spring-Wire I2 or rear end of the key-levers in proper location. The rear portion of each key-lever has a notch ILl in the underside thereof to rest upon the pivotal transverse bar A". The front portion of each key-lever is retained against lateral displacement by a spring-wire I3 passing vertically through said key-lever. The upper end of said Wire is iliade to engage with perforations or serrations upon one edge of a transverse bar A7, secured to the frame, and the lower end of the guide-Wire I3 is made to engage with simi.- lar serrations upon one edge ot' the transverse bar A8, having its ends secured, also, to the frame of the machine.

To regulate the insertion of sheets of paper under and gage them 4beyond the bottom ot the platen, the front rod c of the platen-support is longitudinally grooved, Yand there are adj ustably secured thereon two or more paper-guides c5, made of stripsof sheet metal suitably curved and having' upon their under :face transverse gage-marks properly numbered, so that the printing made upon the first line can be made at the same distance from the top of sheets introduced consecutively under the platen or to note at what point they are taken out to make corrections. These guides c5 are adjustablyretained upon therod c by means of thumb-screws cG passing through the eyes at their upper endand having their end impinging upon said rod.

I-Iaving now fully described my invention, I claiml. The combination of the papercarriage, the frame carried thereby, flat springs adjustably secured to said frame, the platen, and its supporting-arms provided with lateral arms passing un der said spring, substantially as and for the purpose described.

2. The combination of the paper-carriage, the journals ofthe ribbon-spools carried thereby, and a ratchet-wheel upon one of said journals with a spring-pawl carried by the papercarriage and the line space-lever provided with a inger adapted to bear upon the springpawl, substantially as and for the purpose described.

3. The combination of the front rail ot the frame A and scale thereon, the paper-carriage, the platen-supporting frame pivoted thereto, the front-supporting rail of the care riage, and the scale E, pivoted to said rail, substantially as and for the purpose described. Y

4. The combination of a type-bar hanger, the type-bar pivoted thereto, and the bellcrank lever also pivoted to the hanger and adapted to lift the type-bar, substantially as described.

5. The combination of a type-bar hanger, the type-bar pivoted thereto, and a sheetmetal spring secured to the hanger and bearing upon the type-bar over its pivot, substantially as and for the purpose described.

6. The combination ot' a type-bar hanger, the type-bar pivoted thereto, a spring secured to the hanger and bearing upon the type-bar, with a bell-crank lever pivoted to the hanger under said spring, substantially as described.

7. The combination of a type-writing-machine frame having a transverse bar A and transverse serrated bars A4 A5 with a key-lever having a notch I4 and a rearwardly-projecting wire I2 in its rear end, substantially as described.

S. The combination of a type-writing-machine frame having transverse bars AT AB, notched, as set forth, with a key-lever having a wire I3 projecting vertically therefrom between the iinger-keys and the pivot of said key-lever, substantially as described.

9. The combination of a paper-carriage, a platen-carryin g lframe pivoted thereto, springs adj ustably secured upon said frame, a platen yicldingly secured to said frame with a feedroll, and rigid arms connecting said feed-roll to the platen-carrying fram e, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
