Theinvention will-be .described first by reference to the accompanying drawings, and

` A is a rotary bellprovided atits lower edge with a rubber ri'ng X, bearing the printing-V `characters or type. =45

This bell is mounted upon a piston or spindle B, which is arranged to .move longitudinally and rotarilyj'n a tubu at one end and supported et its other end by .a post Fig. 4, so that the` said circleand.

collane. near o ne end and aroundthel spindie,l and between its collar' b and the bottom of.the standard is arranged a spring b to 6` :effectthe automatic-returnof the belli after ithas .beenlowered to make an irnpression. 'Lhecla1np-catch Fig. 1, is adjustable and (forms 'a stopthatperin'its of. the. descent of 'v 7o the' bell A being regulated at will.

The belll A carries a' plunger a, ywhich drops intoone of the holes D.X to arrest andhold .the bellat the character desired to be printed untilthe vbell has been caused to descend and make the impression. The position of. the 7.5

character to be printed and the hole contain: ing the plunger isindicatedat c in Fig.

.'lhe type-ring X may be 'of indiar'ubberLl metalfpr other material or combination of materials' lofv suitable vkind upon which the printing-characters standout, as shown in Fig. 1. This ring is of conical cross-'section and is held vto the beltby means of a flange y,aiixed to said bell. .(See Fig. 14.).

The paper holder or carriage bis." rranged lengthwise of the machine Aand comprisesav plate I, supported above the bedr E and traveling .longitudinally between rollers (l d, ar. ranged upon thebcd E, the pla-te I, and the rollers having, respectively,. c'onvex and'concave engaging edges. This plate'I'is pro-.- vided with an impression-cylinder J and the guiderollers f and ff?, the course ot' the pa e ,per'nbout these devices being shown bythe heavy black line and arrow in Fig. 1, and also 95 in Fig. 8. '.lhe rollerf is arranged in.movable bearings, having any suitable springs acting to impart a yielding pressure of said f roller 7" against the impression-cylinder. The

roller j" is provided with a ratchet-wheel h,a roo' movements of the bell. Thespin'dle B has a V finger or lpawl t', to rotate it by hand, and a dog k, engaging the ratchet-wheel to permit the line-spacing and feeding of the paper linc by line.

The plate I is provided with a toothed rack 'K, which is engaged by a pawl g, pivoted to an arm L2 ot' a lever L, pivoted to a post EX, rising from the bed E. As the lever L is depressed by hand or by the tappet M.of the spindle B upon .the;descent of the bell, the' pawl g is moved, and engaging the rack in conjunction with a tooth L on the lever-arm L3 feeds along the plate I and the paper.

l When the lever L is released, the spring-rod I5 l, acting upon the arm L2, returns the lever and pawl to normal position to be again acted upon, and the pawl g and tooth L are disengaged from the rack by means of a wedgeshaped separator R on a lever R. (See dezo. tails illustrated in Fgs, 6, 7 and the lever The plate l. carries an arm O,

Rin Fig. adjustably secured thereto by a clamp-nut and bolt e. (See Fig. 3.) This arm` O.V hasa finger m, which engages a pin h on the arm z 5' 'n of the striking mechanism of a gong P, and

the Warning given by the sounding of the gong is toV arrange for the Widthof the right' hand margin on the paper. The width of the 'left-hand margin is determined by the stop Q,

3o made. as a thumb-nut and adjustable in a slot Q in the bed. (See Figs. 3' and il.) A

Theinking mechanism (see Figs. 2 and l1) comprises two drums T and U, on which the inking-ribbon lll-alternately is Wound and un- Wound. The drums are supported in suitable brackets T and U depending from the circle D. The ribbon H passes betv'veenfthe ring X vand the impression-cylinder J, and is advanced co-ordinately with the printing or 4e Writing by means of a ratchet-wheel t and a paWl-lever NV, the latter being struck by the vlevjer L as it rises. The weight w causes the lever W tobear upon the lever L, (see Fig4 1-J and when the leve-r L'is depressed the iev'ei" lV follows its movement downward under the action of the weight w', and when lever L rises again under thle action of spring Z it y raises also 4the lever fand the click-w of the latter and causes the click-Wheelzf` to be 5c turned more or less, according to the number of teeth taken by the clicka By these means Y the ribbon ll is advanced. The ribbon ll, being Wider than the type, may be shifted to present fresh surfaces to the type, and this 5 5 may be effected by arranging the bearings of the drums on the brackets T' and U insuch manner that the ribbon-drums may be shifted readily. The plate T2, supporting the d rum, is adapted to slide upon the plate T. A

6o bearing-post fu is fixed to the plate T2 and a bearing-post 'ux is fixed upon the plate '.l", and in these posts is the screw fw. Obviously by turning the screw it; the plate T2 is moved upon the plate/T. A 4screw T, arranged in a 6 5 slot T",'unites the two plates. Similarly plate U slides on the plate Uf, and is secured to it by a screw U2 in a slot ll. The screw fr is lng, while the other is at rest.

.14. -ring X will be so disposed thereon that` one m5 .exposed as tire cover-plate is moved.

supported in bearing-posts ur* and z" on plates U and U', respectively.`

In order to mark accents or sundry signs 7o overletters or characters, I employ the coupled levers S S and s s, Figs. 2 and ll.' One of the levers S. may bear the acute accent and the other the grave, and these two are so arranged that they may in addition form the circumflex accent. In Fig. il one of these levers or keys is lowered, asin the act of print- This provis-V ion of accentingkeys has the great advantage of diminishing the number -oE charac- 8o ters both upon the bell-ring X and upon the indicator, about` to be described, and of facili- 'tating correspondingly' the Working ot' the machine, because the more characters there are on theindicator out of which the eye has to select'rapidly the' right one the greater' thediiiiculty. l'

It is necessary to provide the machine with an indicator by means of which one can ascertain what is the character oneprint-s when 9o the bell is lm v'ered. This amounts. to determining into which of the holes of the guidecircle D the plunger cl, must be sunk in order to print a given letter. This is done on the one hand by means of the fingers B and C', 95

pivoted to the brackets B2 and C2, 4securedto the bell, and on the other hand by means of a series of characters arrangedin aseniicircle around the holes of the front half of the cirele D, and these characters may be engraved, x -o painted, or gummed onto the circle D itself or on anindependent circle D', fixed in any manner upon the circle D, as shown in Fig.

The characters standing out from the halt'ot this ring X will contain,-for example, the capital letters and the numerals `and the other halt the lower-case letters and punetu ation-marks, or vice versa. By this arrangement the indicator need bear only one alphai 1o I bet, and this will serve for both capitals and lower case, according as the linger B or C is manipulated. The indicator will have on the same radius a numeral and a punctuation- 4 mark, and either one or the other will' be 1'15- printed, according as finger B or finger C is manipulated. Y

ln. ordei to avoid mistakes arisiug from using the Wrong finger in printinga numeral for a punctuation-mark, and vice \'ersa,I mayt i zo use a shifting cover-plate d', which is\placed'v over-a series of slots or openings in the circle D', and this cover-plate contains the punctuation-marks and-numerals, either of Which-arc The I 25 The cover-plate 13o plungers a.

- 455,561 l a v shift the said plate back and forth as numerals or punctuation-marks are desired. The indi- 1 e. l letters adopted, (see Fig. l 2,) by 'means of which cater D .may also,bepcombined with a double row of igurescorresponding to the number of one can bya single shifting of the circle D Write a cipher letter, the 'key of which will be given, simply by knowledge of the ligure indicating the Vshifting of the guide in relation to a fixed' indicator of the circle D' of the machine and corresponding to the line o of the circle D for ordinary writing. .lf this indicator be placed, for example, at l and indicate to the person to whom the cipher Y letter is addressedthat the key is l he will know that it means B, and so on, and if such personhas Va similar machine he may with the greatest facility write out the cipher let-A ter in decipher by utilizing in an inverse way the power of movement of the circle D.

` The base of the machine is provided with two feet F and G,-(see Figsand 16,)-Which fold upon hinges when it is desired to place the machine flat, Fig. 3, and which may be turned ont, Fig. '16, to support it at an ineline.

Vhat I claim is-a K 1.*In a writinglmachine, a bell and a typerino affixed thereto a iston and a s rinlT C p t thereon, and a standard upon which the bell is rotatable and adapted to be lowered and raised, combined With a perforated circle and a plunger carried by the-bell and adapted to engage the perforated circl'e,'substantially as described. p
