TYPE-wRlTiNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 354,213, dated December 14, 1886.

Application filed June 23, 1385, Serial No. 169,496. (No model.) Patented in Engand October 2?, i884, No. 13,962.

To @ZZ whom, it may concern:

Beit known that I, EDWARD EDEN PEE- oooi, a subject of the. Queen of England, residing at London, England, have invented new and useful Improvements in Type-Vriting Machines, (l'or which Letters Patent have been obtained in England, No. 13,962, dated October 22, 1884,) ot' which the following is a specitication.

This invention will be best understood by reference to the accompanying drawings, in which like letters of' reference represent like parts.

Figure lis a vertical section showing the machine the full size for a foolscap-machine. Fig. 2 is a vertical section of the inner drum, with details representing a modification. Fig. 3 is a sectional plan of Fig. 2. Figs. 4, 5, 6, 6a, and S are details, and Fig. 7 is a general plan showing the carriage L in the middle of a line.

A is a covered cylinder or drum attachedto the frame, and B is-a smaller cylinder, inside A, (supported upon rollers B', which are located under the liange B",) and revolving upon a vertical axis as the handle O is turned. The types D are carried in projecting tubes D upon the periphery of B, being withdrawn to their normal position by helical springs DE, Fig. l, or by long springs, as in Fig. 2. They are prevented from falling out of the tubes into the interior of the drum B 'by the pins D3,

rwhich, as the types nieve in the tubes D',

travel in slots formed therein.

Where the long springs D2 are employed, I prefer to place them side by side and bend the one which carries the lower type, so as to bring the type in the same vertical line with the upper one, as shown in Fig. 2.

E is the roller upon which the paper is wound, and which may have facets E', if de-V sired, so as to present a flat surface to the type, which, when iinpelled forward, passes through the hole A in the side of A till it reaches the paper,which receives the impression in the usual manner.

The types are arranged in one or more rings or rows around the cylinder B, so that to bring any particular type opposite the opening Al the cylinder B must be revolved so far as may be necessary to accomplish this. This turning of B is managed by incaus ot the handle C, which is jointed tothe arm C of the short tube C2, which 'passes through a hole in the top of cylinder A. Two lugs or guides, C3, serve as an additional bearing for O, between which it lies, and against which it presses when turned. Connected with the tube C2, inside drum A, are two or more arms, 0*, whose depending forked ends O" engage with pins or projections Olson the side of drn in B,wl1ose hollow spindle B2 ts nicely in the tube O, and serves to support the upper portion of B. By turning C, therefore, B also is turned to the saine extent and upon the saine central axis.

The upper plate, Aiof the cylinder A carries the letters or other symbols arranged in rings upon it, as shown in plan in Fig. 7, and around the periphery of the plate are tapered or countersunk holes A3,'in which the pointer O7 is placed, according to the letter required. There is one hole A3 for each letter or symbol, and by placing the pointer CT into the hole corresponding with any required letter the corresponding type D is brought opposite the Opening A, ready to mark` the paper upon the roller E.

As shown in Fig. 7, two sets of letters, 85e., are engraved upon plate A2, but only one set need be represented on this plate if the po-V sition of both sets is the saine, (A always representing A,wl1ether large or small,) the number of dilercnt sets of letters, Src., which the machine can print depending upon the number of rows or sets of types D in the cylinder B.

As shown in Fig. 7, the position of the large and small lettersfof the alphabet on plate A2v correspond; but the position occupied in the larger circle bythe numerals is in the smaller circle devoted to various marks of punctua-l tion. Therefore while printing either large or small letters with a plate so marked, it

would notmatter which circle was followed; I

IOO

by means of the crank B3, secured upon the shaft B, which preferably extends across the drum B, and carries a second crank B3 on its other end. These cranks carry rollers B at their ends, which, when the cranks are turned up, support the drum B at a higher level than before, so as to bring the lower row The length, Y

of types opposite opening A. therefore, of the crank B3 from the center of B4 to the periphery ot' B must be such as to lift the cylinder B the exact distance necessary to bring the lower row of type opposite the opening A. (See Figs. l and 5.)

The drum B is just as free to revolve when raised as when down, as -it is carried on rollers B in both cases, and the spindle 'B'z slides up in the tube C2, and the pins C6 slide up in the forks C5. The shaft B4 is turned in any suit able manner, as by a crank and button, B, outsidethe cylinder A, which may be retained either up or down by any convenient form of spring or spring-detent, such, for instance, as the spring of an ordinary pocket-knife. This crank and button is shown in Figs. 5 and 7.

Having now explained that the printing is accomplished by types D, supported in the revoluble drum B, which types are normally withdrawn into said drum, but are capable of being projected through opening A in the cylinder A, and how the drum is revolved and raised so as to present whatever type may be required opposite the opening A, I will now proceed to show how the types D are forced against the paper. There are two alternative modes of doing this, which are illustrated respectively in Figs. 2, 3, and 6 of the accompanying drawings.

In Figs. 2 and 3,F is an arm or hammer, suitably weighted, if necessary, pivoted at F2, and provided with the projection or strikinghead F, which strikes the type. The pivot end of F is formed into a cam or equivalent, having a spur, F3, upon which rests the end ofa pawl or catch, G, pivoted to the arm or lever G, which is jointed at G2 to the frame G3,which is secured to the bottom of the machine. The cam also carries another spur, F4, which serves as a bearing for the spring F5, secured at its other end to the frame, and by pressing upon the spur F* tending to press the striking-head toward the type. The spring G5 controls the movements of pawl G. The pin H ts easily in the hollow spindle B2, its lower end resting upon lever G, and its upper end supporting the handle C. Lever G is keptraised by spring In use the handle C, which in its normal position is raised up, is turned to the required letter and depressed, the pointer C7 entering the hole A3 corresponding with the letter selected, and the handle then taking the position shown in Fig. l. The pin H is thus forced down, pushing lever G before it. Lever G carries pawl G with it,and pawl G, acting on the spur F3, raises the hammer F, as shown in dotted lines in Fig. 2, until the spur attains such an angle that G can no longer remain upon it, when it slips off and the strikinghead F falls under the iniiuence of its own weight and of the spring F5 sharply upon the type D, driving it forward against the paper which receives the impression. As soon as the pressure is removed from handle C,levcr G at once returns under the influence of spring G6 to its normal position,'raising handle C with it, as already explained.

In Fig. 6 the bolt or hammer I is carried in the frame J, and is weighted at I, the weight l working upon the guide-pin Il. The helical spring'I3 surrounds the bolt I, and when eX- tended iills the space between the end of the frame J and the collar I, secured to or forming part of the bolt I. Oneend of the spring K is fixed to collar I", and the other to lever K, which is secured on the spindle K2, which Y spindle also carries the levers K3 and K4, and is supported in the arm J of frame J, as shown. The lever K (a back view of which is shown in Fig. 6) is in two pieces, connected by a knuckle-joint at K5, and kept normally in the same plane by the spring K, and when at rest it is in front of the lug I5, projecting from the weight I. The action is as follows: The pin H being pressed in by the action 'of handle C depresses lever K3, turning spindle K2, which moves lever K, and so draws back the bolt I and compresses spring I3 between collar I4 and frame J. The radial motion of lever K gradually withdraws it from the lng l until it is disengaged, when the bolt I iiies forward under the iniiuence of spring I3 and strikes the type D sharply on the head, driving it forward, as in the former instance. The forward movement of the bolt I stretches spring K, which, as soon as the blow has been delivered, brings bolt I back until collar I4 presses against spring 13. The spring K, being in a state of tension, pulls lever K back into its former position, raising lever K3, pin H, and handle C at the same time. As K passes back, it comes in contact with lng I5, the spring K6 gives, and the jointed portion of K mounts the rounded or inclined outer surface at I5, and thus slips past, resuming its normal position as soon as it has cleared lug l5.'

The method of traversing the paper so as to cause each sueceedingletter to printu pon fresh paper will be understood by reference to Figs. l, 4, and 8. The roller E, which carries the paper, is supported in a carriage, L, rather longer than the roller and free to travel longitudinally in the guide L. On the under side IIO of carriage L is a toothed rack, L2, Figs. l and tial vertical section taken at right angles to Fig. l, we get a side view of the ratchet-wheel One, M,

M, with which engage two pawls.

is pivoted to the lever M2, which isfree to turn about its center on the spindle L, and the second, M3, pivoted to a bracket fixed to the frame-work of the machine. The end of lever M2 is depressed by the pin M", which is pushed down by the handle C every time it v is worked. This may be managed in any conf venieut manner; but preferably by the lug Gl,

Figs 2 and 3, projecting from the lever G over the top of pin M", and forcingA it down as the lever is depressed. In the modification shown in Fig. 6, the motion oi' pin M* is obtained from the lever K4, which isfsecured upon the spindle K2. The end of lever M'Z (see Fig. 4) is kept against the bottom of pin M4 by the spring M5, and as the pin descends and the lever M2 turns it takes pawl M with it, thus turning the ratchet-wheel M and toothed wheel L, which, gearing with the toothed rack Ll of the carriage L, causes the latter to travel in its guide L', thus presenting` a fresh space ol' paper to the hole A ready to receive the next letter. The various parts are of course adjusted so as to impart the right amount of traverse to the carriage at each stroke.4 The lever M2 has a projecting end or tail piece M, which rests upon the lever M7, pivoted at M8, and is operated by the but-ton M, kept raised when not in use by the spring Mw. It will thus be seen that upon pressing the button M the lever M7 is raised, lifting with it the tail-piece M and depressing M2 and pawl M', thus turning ratchet-wheel M and`moving roller E. This is the method adopted for spacing or providing the spaces between the words.

The pawl M3 serves only as a detent to pre vent wheel M from turning` back and theearriage L from ruiming back to the commencementof its journey, which it would do under the infiuencegof the watchspring L5 unless prevented. Vhen it is desired to return the carriage to the commencement of its journey or teeth of wheel M, which is then free to turn,

and carriage L at once returns under the influence oii spring L5 to its standing-point or until stopped by the release of button N ,when the pawls M and M* ire-engage with the teeth ofM, Fig. 4..

The turning of roller E when a line is completed, so as to present a fresh surface for the next line,is accomplished as follows: Upon the spindle of the roller E is fixed the ratchetwheel O, with which engages the pawl or detent O', pivoted at C)2 upon the movable arm O3, which is pivoted at O* upon the carriage L. Theinclined plate L isixed upon the outer drum or case7 A, as shown in Fig. 8, in a position to engage with the end of O3 during the return of the earrriage L to the commencement desired.

, slots E5 of the ends of carriage L.

of its journey.- As it travels back, the inclined plate forces down the arm O3, and pawl O being engaged with one of the teeth in ratchetwheel O, the wheel, and roller E with it, is turned the required distance to present the uewsurface for thenext line. Pawl O is kept in gear with wheel O by the spring O5, which engages with a pin, O", projecting from 0', and the movable arm. Oi is kept raised (except when depressed by plate P) by spring O7, the stops OS preventing it from going too high and perhaps catching against the end of the plate.

At one end oi' the roller E, Fig. 7, or upon its spindle, is txed the disk Q, indented at the required places Q to receive a spring-detent, Q2. These indentations Q are so spaced as'to bring the allotted space 'for each succeeding line opposite the type-line. The indentations Q and detent Q are so shaped as to hold the roller while the line is being printed, lout yield to the increased pressure exerted by the plate P, the spring causing the detent promptly to engage the next indentation when one' has passed. The milled knob Q3 is provided upon the end of the roller-spindle' for the purpose of turning the roller by hand.

For the purpose of retaining the paper properly upon the roller E, and preventing it from crumpling, the two small rollers E2 are provided parallel with roller E, joprnaled at each end in slots E* in the ends of carriage L, Figs. l and 7. They are kept in place and pressed upon roller E by the rubber rings E, one at each end, and can be readily removed when The roller is also readily removable, being journaled in a similar manner in the The upper one of these rollers, or, if preferred, a crossstay, which binds together and strengthens the ends of L, is marked or graduated in any convenient manner, so that by referring to the in` dex E, which is ixed to the casing A in a vertical line above the hole A, through which the printing is effected, the operator can tell how much of a line is printed and where to stop. i

As an additional safeguard to prevent overrunning the paper, the belt T is provided and' secured to the casing A. The tail of the hammer T projects, as shown, so that it may be moved by the arm TZ, which can be set at any desired position upon the graduated roller E2 or upon the stay or other portion of the carriage L. The graduated roller or stay is, however, preferred, as the operator knowing the size of the paper he is using can at once set the arm in the proper position by the marks without having to measure. The arm moves along with the carriage till it comesin contact with the hammer-tail T', which is moved with it till it slips past, and under the influence of a spring, in the ordinary way, flies back and rings the bell.

The inking device is shown in Fig. 5, and consists of two rollers, R R, capable of revolving upon vertical spindles outside the case A. The first roller, R, has a hollow spindle, R2,

roo

closed by a cap, R3, and perforated so as to allow the ink which is poured into the hollow spindle to pass to the roller R and be taken up by the absorbent material of which it is composed. The second roller, R', touches the first one and receives the ink from it. It projects through an opening, A4, in the case A, so that as the inner cylinder, B, is revolved the types are successively brought into contact with it and their faces inked as they pass. Vhen irst starting to use the machine, the drum B should be revolved a few times, so as toink all the type. After that the turning of the drum necessary to the use of the machine is sufficient to keep the type inked.

The [irst roller, ll, must either be made of or covered with absorbent n'iaterial-such, forinstance, as Vfelt-Which will absorb and retain the ink. The second roller, R, may be made of material suitable to the nature of the ink intended to be used. YVhen roller R is only covered with the felt o r equivalent,the central portion must be of open material, such as will permit the ink to pass through, or holes must be madeinitto allow of the ink passing. These rollers are protected by a suitable ease, S, which may be hinged at S', so that it may be moved out of the way when the rollers have to be got at, as for cleaning. There are preferably two sets or pairs of these inking-rollers; but any convenient number, from one upward, may be used.

I claiml. ln a type-writer, the combination, with a stationary cylinder provided with a single opening, a rotatable tubular type-carrier inclosed therein and carrying a series of type in superposed peripheral rows, operated to be projected through corresponding peripheral openings in said carrier, and a central shaft around which the type-carrier revolves, of a lever connected With the type-carrier for rotating and positioning the same to bring a typeAopening and type to register with the opening in the cylinder, said type-carrier having a vertical movement upon the central shaft independent of the lever, and means, such as described, for adjusting the carrier vertically, as and for the purpose specified.

2. The combination, with the carriage L, toothed on its under side,a gear-wheel mounted on a horizontol shaft and meshing with the teeth on the carriage, and a spring acting upon said shaft. of the ratchet-wheel M, the rods MT N', keys M9 N, lever M, paWls M/ and M3, and spring M5, said parts being arranged and operating substantia-lly as and for the purpose specified.

3. The coi'nbination, with the longitudinally sliding bolt I, weighted at one end, the levers K K3 Ki, pivoted on the same shaft, a stop on the Weight of the sliding bolt, and the shaft H, of springs for shooting the bolt I and returning the various parts into their normal position, said parts being arranged and operating substantially as and for the purpose specified.

In testimony whereof' I have hereto set my hand in the presence of the two subscribing Witnesses.
