TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No.

l To all whom it may concern Be it known that I, CARL MCKINLEY, a citizen of the United States, residing at /Vashington, in the District of Columbia, have invented a new and useful T 7pe-riting Machine, of which the following is a specication.

My invention relates to improvements in type-writing machines in which a laterally and vertically swinging handl lever or key operates by its lateral motion a t 'pe-wheel, and by its vertical motion a printing lever or hammer and paper-feeding device; and the objects of my improvements are, irst, to produce by very simple means and manipulation a neat and clear print of large or capital and small letters, punctuation-marks, numerals, and all other characters and signs used in ordinary writing and printing; second, to effect an instantaneous changein the use ofthe different kinds of letters, characters, signs, Sto., withoutinterruption of the printing process; and, thirdly. to substitute entire groups, classes, or styles of the type used, one for another-as from Roman to Italic, plain to ornamental, Greek to Hebrew, Ste-with such readiness of action as to occasion but triiiing delay in the operation ot' the machine, at the same time that its scope is thereby enlarged to an almost unlimited extent. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation of m y type-writing machine, a part of the platform being broken -away in order to expose the mechanism otherwise hidden by it; Fig. 2, atop view ot' the same, Fig. 3, a bottom View of the same. Figa is acentral longitudinal section of the feeding device. section in the line x of Fig. 4. Fig. 6 is a top view of a type-shield, as will be explained.

Similarletters refer to similar parts through out the severa-l views.

Aisa platform, supported bylegs c or other suitable means. B is an arm fastened to the rear part of the platform, which, by preference, is inclined at an angle of about thirty degrees, in order to facilitate the reading of the printed matterduringthe printing process. By means of A and B the devices for operating the typewheel, the printinghammer, and the feed movement are supported.

p low the A, and a suitable p means of springs e2, fastened to the platform A.

Fig. 5 is a transverse 232,741, dated september 2s, 1880,

, Application filed July 14, 1880. (No model.)

To the front part of the platform A a bearing, C, is attached, by means of a vertical pivot, c. (Shown in dotted lilies in Fig. 1.) To this bearing a lever, D, is attached, by means of a horizontal pin, d, and thus the said lever may be moved vertically and horizontally.

The lever D may t0n, d',

be provided with a butand a pointer, d2, at its free end. Bebutton a wedge, d3, is formed, which tits into similarly-shaped notches c in a sector-plate, E. This plate E swings on two arms, c', suitably hung to the bottom of the platform apertureis made in the platform to allow the plate E to swing up and flown, as is shown at a in Figs. 1, 2, and 3.

The plate E is held in its normal position by in a suitable way In front of the notches e the letters, punc mation-marks, and other characters to be used are marked to guide the operator, the central notch being left blank to correspond with a similar blank space on the type-wheel, for the purpose of producing the necessaryinterval or spacing between the words as written orprinted in ordinary practice.

The letters ofthe alphabet, characters, Ste., are arranged alternately on either side of such blank space or central notch inl the order of the frequency of their respective use, so that those which are most used shall lie nearest to such central notch, and those which are less used at proportionately greater distance and in proper order, as explained. The number of notches in the sectorplate E will somewhat exceed the number of letters ot' the alphabet, if necessary 5 but it is intended that each such notch sh all represent, say three different types orcharacters, (the centralnotch alone excepted, by reason of its specific ofce,) only one of which can be printed at a time, subject to the will of the operator.

Behind the plate E a plate, F, is provided, which moves in a suitable aperture, c2, of the platform A, and is attached tothe lever F of the printing-hammer, and above the said plate F the lever D has a project-ing abutment, d4, which touches the plate F as soon as the wedge d3 is seated in one of the notches e.

The rear arm of the lever F ends with a turned- IOO up head, f, which may be covered with leather or other suitable material, and which constitutes the printing hammer or head. This printing-hammer stands opposite an oscillating and revolving type-wheel, G, which is provided with a number of rows of types of letters and other characters, g, three such rows bein gindicated inthe aecompanyin g drawings. The types g may be the same as those used in ordinary printing, and may be inserted in suitable socket-holesin the type-wheel and secured in place by a little solder. modes of fastening may, however, be adopted nstead of this device.

Types of any suitable material, and with or without hardened surfaces, may be usd.

The type-wheel, again, may be composed `of a number of wheels, each provided with a circular row of suitable notches adapted for the insertion of types, which wheels may be suitably screwed or otherwise fastened together, so as to clamp the types tightly between them or the type wheel or wheels may be solid and having the letters and characters engraved upon their cylindrical surf'ace.

Instead of such type wheel or wheels, as above described, havin graised letters and characters, stencils maybe used,arran ged in a suitable manner upon the wheel G. The letters and characters upon this wheel Gwillextend around the surface of the wheel at regular intervals, with suitable spaces between, and in an order correspondin g to that of the same letters and characters upon the sector-plate E, a blank space beingleft upon the type-wheel to correspond to the similar blank space upon said sectorplate, for the purpose of producing the proper spacings between words, &c., as already eX- plained.

On the rear part of the bearing C a toothed sector-wheel, c', is formed, into which a conical toothed wheel, g, is iliade to gear accurately. This wheel g is attached to a shaft, g', suitably hung in the arm B, which shaft carries the type-Wheel G by means of a sleeve, g2. A transverse pin, g3, causes the sleeve and the type-wheel attached thereon to revolve with the shaft g', while a longitudinal slot, g4, allows said sleeve and type-wheel to be moved longitudinally upon it.

A loose collar, g5, is placed upon a suitable reduction of the sleeve g2, and is held there bymeans of a rigid collar, gs, so that the collar g5 may turn on the sleeve without longitudinal movement. v

Two trunnions, g'f, are provided on the collar g5, and these trunnions are fitted into the forked head t of a connecting-rod, It. This device serves to move the sleeve gz longitudinally without hindering it from revolving; and as this is a general and well-known device whichis often used in machine-building I have not ldeemed it necessary to illustrate it by special sketches and detail views.

The connecting rod h is attached to the lower arm of a lever, i, in the arm B, which is 'of the lever t' a horizontal slide,

Other suitable e suitably hollowed out to receive thelever and allow it free movement, and to the upper arm I, is attached, which is suitably fitted into the upper part of the arm B, and is provided with a handle, t', and a stop -lever, t2. The lever t2 is pivoted at t3 to the slide I, and extends forward beyond the slide, and ends with a head, t4, which is made to enter notches b in the bottom of the bearing provided for the slide I. A spring, 5, fastened to said slide, and bearing against the lever i2, serves to keep the head t* in whatever notch it may beplaced. These notches b correspond to the arrangement of the rows of types g8 on the type-wheel G, and by moving the slide I and allowing` the head t4 to enter the first, second, or thirdnoteh, b, respectively, the first, second,or third row of types is moved into the required position for 'printingfrom them, immediately above the printinghammer f, and is held there.

The sleeve g2 has one rigid bearingin a projection of the overhanging bracket or arm B, as at b2, and may have one removable bearing, b3,fastened toI the end of the arm B by means of a set-screw, b4. When the bearing b3V is removed free access to the type-wheel can be had, and that wheel may be readily removed and another' similar wheel, bearing, however, an entirely different set and style of letters, characters, Ste., be. quickly substituted for it to meet the tastes of the operator or the requirements of his work. This substitution can be effected, as is apparent, without disturbing any other portion of the mechanism.

Upon the rear end of the lever t2 another lever, J, bears, which is pivoted at j to the arm B, and has a vertical slide, K, attached to it by means of a pin, 7c. Thisslide K is tted into a suitable vertical slot inv the arm B, and its lower part is forked and has an inkwheel, J', hung to it. A spring, j', fastened to the arm B, bears upon the slide K, and thus causes the lever J to be always in contact with the lever t2. Thus when the lever t? is turned upward the ink-wheel J is4 lifted off the typewheel Gr, and the type-wheel can bev shifted longitudinally by means of the slide I without clogging the face of the type with ink.

An ordinary inkin g device for supplying ink to the ink-wheel Jl and suitably distributing the same upon its surface will, in practice, be fastened to the arm B and connected with said ink-wheel, or, if it should be deemed necessary or preferable on any account, the inkwheel and inking device, as abovedescribed or referred to, may be discarded altogether and its place and ofce supplied by theink band.

or ribbon now in general use, which would'be suitably attached to the arm B in such. manner asto bring said ,inkband1 or ribbon 4into the proper position for printing,to wit, above the paper and between the surface of the typewheel and printing head or hammer.

Below the type-wheel two rollers, L L', are hung in a suitable frame, l, one side of which IOO IIO

IIS

QSQJME 3 frame slides in a groove, a, of the platform A. The center of said frame Z consists of a longitudinal rib, l', with ratchet-teeth Z2 at the bottom. This rib Z slidesin atransverse guidegroove, et, formed in the platform, which guide closes around the sides and bottom of the rib ZL, with thev exception of the bottom on the right side, which is open to the center. The left end of the rib is provided with an arm, m, to which the end of a clock-springis attached. This clock-sprin g M is suitably attached to a pin, m', of a stand, m2, on the platform A. The tendency of the spring M to wind itself upon the pin m serves to pull the frame Z from the right to the left, and thus furnishes the power for a self-feed ofthe paper. This feed is controlled by an escape-lever, M', suitably hung to the platform A and provided with an angular arm, m3, which extends under the lever F ofthe printing-hamn'ier, and is held upon said arm by means of` a tension-spring, m4.

The stroke of the lever F being greater than that of the escape-lever M', it follows that the operation of the latter takes place before and after the printing, and the paper is not moved during the actot printing.

Upon the roller L they paper X is rolled, and as it is discharged therefrom to the roller L it passes under a guide-roller, L2, suitably hung tothe frame I, and is thus held even with the surface of the platform A. In passing over the rollerLl the paper is pressed against it by a roller, L3, of elastic material, whereby it is caused to move evenly, and with a slight tension between the rollers L and L. Each of the said rollers L L may be provided with a pulley, Z3, over which a cord, Z4, is passed, which keeps the rollers in uniform movement and enables the operator to move the paper with either hand by means of a thumb head or button, Z5, secured to the right end of roller L and to the left end of rollerL Thislatter device, which constitutes the transverse feedmotion, serves to locate the paper for the new or next line, when one has been printed, and so on consecutively, and is worked by hand. A dial-plate and pointer or ratchet wheel and pawl may, however, be used in connection with one of the rollers in order to insure accuracy of spacing between the lines of print.

A bar, f, suitably fastened to the platform A by means of screws a, forms the upper part of the groove a3, and when the frame Z is to be taken out of its bearings this bar a7 must be first removed.

A type-shield, N, is suitably fastened to the arm B, and extends under the type-wheel G, where it is provided with an aperture, n, sufficiently large to admit of the printing from any required type, while it prevents the neighboring type from being touched by the paper.

Operation: The ink-wheelhavin g been properly supplied with ink, or the ink-ribbon having been placed in position, as described, and i a sheet of paper of any width less than the length of the rollers L L having` been proppointer cZz upon the plate E.

erly and neatly :rolled upon L, its free end is passed forward under the guideroller LZ and suitably inserted between the rollers L L3. The operator now moves the frame Zto the right, which causes the ratchet-teeth Z2 to slide over the ends of the escape-lever M and winds the spring M upon the pin m until the paper is brought into the desired position under the type-wheel for receiving the imprint of the first letter. The operator next moves the lever D into a notch, e, representing the letter or character he desires to print, whereby the corresponding type upon the type-wheel G is brought uudermost and into position above the slot n in the type-shield N and above the hammer or printing-head f. The wedge Z3 is now pressed into the notch e, already indicated, and the downward pressure is continued until the notched plate E is depressed as far as possible, whereby the abutment (Z4 is caused to press at the same time upon the plate F,

which throws the hanimer f up'against the' paper, which, in turn, receives a correct print from the 4superimposed type, this print being that of the letter or character indicated by the The lever D is now lifted above the plate E. This plate and the lever F resume their normal positions, and the latter in so doing moves the arm mof fthe escape-lever M downward, whereby the frame Z and the paper which it bears are `moved to the left the distance of one-half a tooth, Z2', or of one-hait' the width between the ;types g, measuring from center to center. By the next upward movement of the lever F the aim m3 is moved up by the spring m4, and the position of the escape-lever M is reversed, and thus'the frame Zis moved to the left the distance, again, of one-half the space between the types, as already explained. VIt isseen,`

therefore, that two movements of the escapelever M take place between the printing of each letter, whereby the distance which the frame Z is moved to the left always amounts to the full space between the types g8, as is required. ln this manner the printing is continued; but when a change of type is required, as from a small letter to aeapital letter, or for the purposes of punctuation or insertion of figures, Sec., the corresponding row of type on the type-wheel is moved into the necessary position by moving the slide I. This is accomplished by pressing the handle 'i' and stop-lever Z2 together by means ot' the thumb and forefln ger of the left hand, preferably,- and moving the slide I until the head it of the lever 112 stands opposite the correspon ding notch b in the arm B. The lever D is then turned opposite the desired auxiliary letter or character marked upon the plate E, and the printing goes on, as before described. lf more than an ordinary space is required between two Words or sentences, or for theconclusion of a paragraph, die., the lever D is moved down into the central notch on the plate E as many times in succession as may be required to ef- IOC IIO

feet the desired end, and a blank space will appear on the paper of as many type-widths as there may be movements of the lever.

When letters and characters of different sizes, or styles, or kinds are required to be used the type-wheel is removed by first removing the bearing b", then unscrewing the nut gm and slipping the type-wheel from the sleeve g2. Another type-wheel, with the type desired, is then placedin position upon the sleeve g2 and secured between the collar 99 and nut glo, the bearing b3 is replaced and the printing may be resumed from the point where it was discontinued, or elsewhere.

The lever F' may be extended forward under the plate E, as indicated in dotted lines, and be operated by the saine, in which case the plate F and the abutment d4 will be omitted.

This modification,however, would not alterthe principle or any essential feature of my invention.

Another modification of my type-writer consists in the arrangement of the main parts, so that the arm B, with the shaft g', shall be at right angles to its position, as indicated in the accompanying drawings, and to the lever D when thatlever is at rest in the central notch ofthe sector-plate E. This modification would require the toothed sector-wheel c' to conform to the changed position of the conical toothed wheel g, and the lever F' to be so changed in direction as to bring the hammer-head f into proper position to conform to the changed position of the type-wheel G. The rear portion of the platform A would also be in the same plane with the front portion, as the inclined position would be no longer desirable. These several rearrangements also, as is apparent, would involve no alteration of the principle of the invention, or of any essential part, but would reduce the machine to somewhat more compact form, and would bring the paper and printed lines nearer to the hand and eye of the operator, as might be preferable in certain cases, not necessary to be specified in this connect-ion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore set forth, of the horizontally and vertically moving operating-lever, the revolving type-wheel having the circumferentially-arranged types, Ste., the shaftwith which said type-wheel turns, the gearing connecting said shaft and operating-lever, and the printinghammer actuated by the operating-lever to press the paper against the type-wheel or inking-ribbon.

2. The combination of the vertically and horizontally moving operating-lever, the bearing C, turning in the platform and provided with a sector-gear. and to which said lever is pivoted to play vertically, the type-wheel supporting-shaft provided with the gear-wheel meshing with said sector-gear, the sleeve reciprocating on and turning with said shaft, the type-wheel fastened on said sleeve, and provided with circumferen tially-arran ged rows of types, &c., and the printing-hammer actuated by the operating-lever, substantially as and for the purpose hereinbefore set forth.

3. The combination, substantially as hereinbefore set forth, of the platform, the printing-hammer beneath it, the arm .overhanging the platform, the type-wheel having the circnmferentiallyarranged rows of types, &c., the sleeve to which the type-wheel is fastened, the turning-shaft supported by said overhanging arm, and with which the type-wheel sleeve turns while having the capacity of movement endwise thereon, and means, essentially such as described, for sliding said sleeve along its shaft to bring one or other of the rows of types, Src., into the described position relatively to the printing-hammer and secure the type- Wheel against accidental endwisemovement while admitting of its rotation.

4. The combination of the printing-lever F', having a spring, m4, the spring M, escape-lever M', having arm m3, and the feed-frame l, constructed and operating substantially asy set forth.
