IMPROVEMENT IN TYPE-WRITING MACHINES.

Specification forming part of Letters Patent No. 1 81,463, dated August 22, 1876 application filed February 5, 1876.;

To all whom it may concern:

Be it known that I, GEORGE H. MORGAN, of Alexandria, in the county of Alexandria Machinery; and I do hereby declare that the following is a full, clear, and exact description: thereof, which will enable others skilled in the art to-which it appertains to make arid use the same, reference being had to the accom panying drawings, and to'the letters of referoccupyz'. 0., properly spaced, or withproper spaces between the letters of each word, and

- between the words-themselves, and with mechanism so arranged that the spaces between the letters of each word,'and between the ing-hammer at the right moment.

In this machine I accomplish the same result by means of a type-wheel, also; but the types are not arranged upon independent and adjustabletype-carriers, but are inserted radially in a revolving wheel, the letters of the different'alphabets or styles being inserted in parallel circles, each. style .in its own circlethatis to say, all thecapitals of the same style in one circle; all the common text-letters of the same style in another circle, italics in another, and soon, each different style-or, size of letter having a circle of-its own, and so that each'letter in its different-styles shall run in a line parallel with theaxis of the wheel. Said improved wheel is made: adjustable, soas'to. bring thedesiredstyle of type opposite a fixed point Where the required type is made, through suitable means, to receive an impulse or motion which brings it in contact with the paper I to be printed. The invention furtherconsists in a new and improved mechanism for operating this new. type-wheel, said mechanism being hereinafter more fully set forth.

In the accompanyingdrawings, Figure l is a vertical sectional view ofa machine embodying my improvement. Fig. 2 is a side view of the same, also in vertical section. Fig. -3 isa plan view of the cylinder in section. Fig. 4 is a plan view of the type-wheel and cylinder, also in section. Fig. 5 is a vertical sectional view of the type-wheel, detached. Figs..6 and 7 show the detached view of the slidingc'am-rods. Figs-8 and 9 are detached views of the type-moving levers. Fig. 10 is a .detached view of the type, the stem ofthe type, and the spring for returning the 'type to its normal position. Fig. 11 is a detached viewof oneof the cam-rods.

Referring to the parts by letters, A-represents the framework-to which'the partsof the machine are journaled, or otherwise suitaably attached. B represents a vertical shaft journaled in suitable bearings in the frame A, =and0 is a horizonal shaft suitable to a journ'alin the frame A, by means of which mo- .tion is imparted to the machine, any'suitab'le power-being applied. D and D are beveled gear-wheels keyed upon the shafts OandB, respectively, through which the motionistrfan smitted.- F is a cylinder keyed to the shaft-B, so as to revolve with it. ,The upper portion of the cylinder Fis made of greater diameter than :thelower, and thewhole is formed with a series of longitudinal grooves, f, which extend throughout its length. A series of circumferential grooves, f ,are also formed inthe'periphery of the lower portion of the cylinder Theitwo upper of these circumfervential grooves f are formed on the portion of the cylinder having the greatest diameter. E represents a series'of rods 3 having cams-e on their upper ends, ,andga series of grooves, .3 corresponding in numberwith the circumferential grooves in thecylinder. 1 The end groove e hasa beveled face or cam, e Grepresents aseriesof pivoted bars, the outer ends of the cylinder.

position.

which are formed into finger-keys g. H represents a series of rods or vertical bars corresponding in number with the keys g. The lower ends are screw-threaded,and passed through slots in the bars G, and providedwith adjusting-screw wheels or nuts 9. h h represent spiral springs, which encircle the lower ends of the bars H. The upper ends of these bars have each a cam orprojection, h. Irepresents a series of horizontal rods or bars, having projecting ends, provided with keys or cams 1'. These rods are pivoted to adjustable brackets J, secured to the frame of the machine, and are provided with springs j. p The keys Gr, rods H, and cam-bars I correspond in number with the circumferential grooves in the lower part' of the cylinder, and operate the rods E, in the manner hereinafter more fully set forth. K represents a series of le vers pivoted at the lower ends in the longitudinal grooves formed in the upper part of They also correspond in number with the rods E, cam-bars Gr, rods H, and

keys g. On the'inner side of the upper end these levers K have a cam-projection, k, and

on their other side a projection or key, k. L i it represents the type-wheel loosely mounted on the shaft B, and made so as to fit over a portion of the upper end of the cylinder F, as shown in the drawings.

It is formed with a number of series of radial slots, 1, arranged inparallel lines, as clearly shown in Fig. 5 of the drawings.

M represents the type, and N, type-shaft,

having a head or projection, 02, on its inner end. n represents spiral springs placed around the stem N, which bear against the innerside of the outer plate of the type-wheehand against the head it. These type, with their stems and springs, are inserted in theslots l in the wheel. The wheel L has a central pro jection, L, on its upper side, formed with a circumferential groove, 1.

O is a sleeve, which may be made in two pieces and clamped together, and loosely mounted upon the shaft B. It has an annular key-ring. which fits the groove 1. One side of this sleeve 0 is formed into a rack-bar, 0. P'represents a segmental gear pivoted to the frame of the machine, and having teethwhich engage with the rack-bar 0. Q is alever, one

-end of which is secured to the pivotal shaft of the gear P, and its other end passes out through the side of the machine, upon which is formed a series of notches, q, or other. means for securing the end of. the lever in the desired It is a band-wheel on the shaft 0.

I have not shown any device for carrying or feeding the paper in this specification but i the grooves f? on the enlarged upper portion of the cylinder Fare designed. for the recep-.

tion of the ends of cam-levers, which actuate mechanism for operating the paper-carriage, the paper being fed as indicated by dotted lines in Fig. 2 of the drawings, S being afixed plate or platen, against which the paper is pressed by the type in the operation of printing.

The paper-carriage and mechanism for oper-.

ating the same will form the subject of another application for Letters Patent, for which I am about to apply. t

The operation of the machine is as follows: Motion being imparted to the shaft 0 by any suitable power, and the miter'wheels D l) gearing with each other, the cylinder and type- Wheel will be rotated at the same rate of speed, the sleeve 0 remaining stationary, and

the ends of the cambars I being held clear of contact with the rods E by means of the springs j. When it is desired to print with the machine the type-wheel L is adjusted up or down on the shaftB by means of thelever Q, segmentP, and rack o of the sleeve 0, so as to bring the head of therequired type or style of type in its circle, to be printed, direct- ,ly oppositetothe projections k on the upper end of the levers K. The desired style or size of type will now be in a position for printing. The operator then presses upon the key representingithe letter to be printed, depressing the key end of the bar G, and raising theend to whichthe rod H is attached, thereby forc-.

ingthe latter upward, so that the -projection h on its upper end willpress upon thecorresponding cam-bar Iuntil its key or cam 5 comes in contact with the beveled face of the rod E, pulling the latter down, so that the projection or cam e on the upper end of the rod E will operate upon the projection k on lever K, and

force the projection 10 against the head of the type, so as to move the type outward against the paper. i

The intermediatelever K may be dispensed with, and the rod E, through its cam e, made to act directly on the inner end of the type, the stem of the type being suitably constructed for the purpose, and made to project through an annular stay-plate on the inside of the type-wheel; but I prefer to use the. inter- I mediate lever K inconnection with rodE.

After the letter has been printed the stationary cam or plate :vwill come in contact with the beveled face e as the cylinder revolves, and push the rod E up again, so that the cam 0 will pass above the cam 70 and permit the type to come back to its normal position through the operation of the ispiral.

spring n. v t i t In doing this it will have forced the type out again, but at a time when it will not come in contact with the paper; As the type-wheel revolves the type come in, contact with-the inking-roller before coming tothe printingpoint, and the paper moves at the required rate of speed from right to left, it being operated by suitable mechanism, receiving motion from cam-levers, the ends of which. project.

into grooves f, as before described, so that the rods E will actuate the said leversat the same time that they operate the leversfor forcing out the type. In this way the same mechanism moves the paper and prints the letter at one and the same time.

The second outward movement of the type, caused by the return or upward movement of the rod E, may be utilized to press the type against the inking-roller.

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

1. A revolving type-wheel,L,havin g abackand-forth movement on its shaft, and having the same letters, in different styles or sizes of type, arranged circumferentially in parallel circles, the letters of each style or size being I confined to their own circle, and each type capable of independent movement, for the purposes specified.
