SPECIFICATION forming part of Letters 1? A Application filed March 4, 1903.

T0 aZl whom it may concern:

Be it known that I, HIDALGO MOYA, a citizen of the United States, and a resident of. Leicester, in the county of Leicester, England, have invented an Improved Type- Writer, of which the following is a specification.

My invention relates to type-writers, and is an improvement on the type-writer described in my application, Serial No. 125,037, filed September 27, 1902. In that application I have described a type-writer in which the characters are each brought into a position ready to make an. impression at the proper place on the paper by the movement of a typewheel about the axis of which the characters are arranged in circumferential rows and also in crossing rows, so that all the characters in any crossing row can be brought into a certain relation with the paper-roll, and the paper-roll is then moved sidewise to bring it into printing relation with any one of the characters in that crossing row; and my present invention consists in a type-writer of that class in which the type-wheel can be thrown forward as a hammer to make the impression after the proper crossing row has been selected by the angular motion of the type-wheel and the proper type in that crossing row has been selected by the sidewise motion of' the paper-roll. While this is the distinguishing characteristic of my present invention and while it is due to this feature mainly that I am enabled to largely reduce the number of parts, and thereby greatly simplify the construction and operation of. my improved typewriter, yet other features of my invention explained below and defined in the claims have much to do with the practicalfattainment of these objectsnamely, firmness of parts, simplicity of construction and operation, and also economy in building and durability in use.

In the drawings, Figure 1 is a plan View, with parts removed for clearness, of my improved machine. Fig. 2 is a section through Fig. 8 is a detail of the means Fig. 4;

is a detail of the clutch-operating means to connect and disconnect the cam with the shaft of the type wheel. Figs. 5, 6, and 7 are deatent No. 752,795, dated February 23, 1904;.

Serial No. 146,152. (No model.)

tails of the type wheel cam, its shaft, and clutch. Fig. 8 is a detail of means for moving the paper-roll sidewise. Figs. 9 and 10 are details of means for moving the paper-roll endwise, Fig. 9 showing the under side of the supporting-frame of the paper-carriage and Fig. 10 being an elevation of partof Fig. 9.

I have shown the characters arranged on a cylinder A in six circumferential rows, each with fourteen characters, and with the characters of these circumferential rows in fourteen rows lengthwise of the cylinder, thus giving eighty-four characters in all, each one of which may be brought into the printing-plane by mechanism which moves the type-wheel A angularly to bring any lengthwise row of six characters into a plane crossing the paper-roll G. (See Figs. 2 and 3.) My mechanism for thus selecting any one of the fourteen lengthwise rows is actuated by any one of fourteen character-keys, and mechanism for moving the paperroll sidewise selects any one of the characters in the second, fourth, and sixth circumferential rows, counting from the bottom of the type-wheel, when the proper lengthwise row has been brought into the printing-plane,.

while any one of the characters in the first, third, and fifth circumferential rows, counting from the bottom of the type-wheel, is selected partly by the angular motion of the type-wheel, partly by the sidewise motionof the paper-roll, and partly by the lengthwise movement of the type-wheel, so that fourteen additional keys are adapted each to give the type-wheel a lengthwise movementin addition to its angular movement.

Each of the. twenty-eight character-keys also gives the- The paper-roll has of course the usual lengthwise motion step by step for spacing for letters and words and the usual rotary motion type-wheel A is splined (in order that it may be moved endwise on shaft f for the purpose explained below, and cam E is connected with 1 shaft f through a clutch whose movable mem- A angularly while resembling somewhat mechanism heretofore used for a like purpose yet differs substantially in its construction and mode of operation from any heretofore known, for the reason that it is based on a clutch connecting the shaft of the type-- wheel with a cam or other shaft-actuating means and mechanism common to all the character-keys for operating the clutch to free the type-wheel shaft from the cam when thetype wheel and its shaft have been moved through the proper angle to bring the desired lengthwise row of characters into the printingplane, so that while the cam is rotated by each character-key through substantially the same number of degrees, yet the cam is disengaged from the type-wheel as soon as the: proper lengthwise row of characters is the longer arms of levers D are'forked, as.

shown in Fig. 1, the end of one tine of "the fork engaging one groove of cam E and the corresponding tine of the fork of the other le- 'ver D engaging the opposed groove of cam E, so that whichever lever D is actuated the cam E is rotated, but in one direction by one lever and in the other direction by the other lever. Cam E is mounted on shaft f, upon which berf is splined to shaft f by disk f fast on shaft f. The clutch member f is made with" a leg f and a foot f sliding on shaft f, as

shown in Figs. 5, 6, and 7. Spring f normally holds member f in engagement with the other member f of the clutch, fast on cam E. The foot f supports the free end of shipping lever f pivoted at f and lever f is depressed by arm'f of frame f pivoted on rod f The cross-bar of frame f extends across under all of the character-keys and is stepped to vary the time during the rotation of cam E when the clutch member f shall be operated to free shaft f from cam -E, and thereby leave type-wheel A in one of its. fourteen different angular positions with relation to its normal position with its neutral line in the printing-plane.

The shipping-lever f carries a bolt f, which engages the rack or disk f just as shaft 6 f is 'unclutched from cam E, and thereby locks shaft f and type-wheel A in their desired angular position with one of the fourteen lengthwise rows of characters in the printing-plane.

When the character-key which has been depressed returns to its normal position under force of its spring I), Fig. 2, the lever D returns to its normal position under force of its spring 0? and returns frame C to its normal position, which permits the stepped bar f to return to its normal position under force of its spring f and thusleaves shipping-lever f free. Thereupon clutch-spring f returns clutch member f into engagement with clutch member f and frees bolt from rack or disk f so that shaft f, type-wheel A, and camE return together to their normal position as lever D returns to its normal position. This mechanism necessitates the use of only as many character-keys as there are angular positions to which the type-wheel A must be brought in this case fourteen, not counting the neutral position of type-wheel Aand if there were only three circumferential rowsof characters on type-wheel A instead of six the sidewise motion'of the paper-roll G to one of three positions would suffice to print any one of forty-two characters with only fourteen character-keys. This shifting of the paper-roll sidewise to either one of three positions is accomplished by the mechanism shown in Fig. 8, in which the carriage for the paper-roll G ismounted on frame g, pivoted at g and actuated through link g bell-crank lever g and key-lever a. When the parts are in the position shown in Fig. '8, the paper-roll G is in printing position relatively to the second circumfe'rential row of characters from the bottom of type-wheel A, and frame 9 rests on stop g but when key-lever g is lifted and caught by catch g the paper-roll G is in position relativelyto the fourth row from the bottom of type-wheel A, and when key-lever g is caught by catch it is in position relatively-to the sixth row from the bottom, as will be plain without further description, for this mechanism is substantially the same as that shown in my pending application above referred to.

Any of the forty-two characters in the second, fourth, and sixth circumferential rows may thus be selected by the combined angular motion of the type-wheel and sidewise motion of the paper-roll by the use of the proper key of the fourteen keys which are used for characters in the second, fourth, and sixth circumferential rows from the bottom of the typecylinder, 'and'the simultaneous use of the stops 9 g, and 9 each of which represents one of these circumferential rows. To provide for selecting any of the other forty-two characters in the first, third, and fifth rows from the bottom of the type-wheel A, the other fourteen keys engage, when actuated, cross-bar H, Figs. 1, 2, and 3, which is the cross-bar of a frame pivoted on rod f This cross-bar H is slotted below the first fourteen keys B, so that neither of them will engage it, but is left Whole under'each of the fourteen keys B, and

whenever any key B is depressed it carries cross-bar H with it and swings cam-arm It against earn it, carried by fork k pivoted at It" and straddling shaft f below type-wheel A, thereby moving type-wheel A endwise and bringing one of the circumferential rows one, three, or five from the bottom of type-wheel A into printing relation with the paper-roll G in accordance with the then position of that roll, as before explained. When any one of the eighty four characters has been thus brought into printing position, the impression is made by using the type-wheel as a hammer. This is done by mounting the shaft fin a swinging frame J pivoted at j and provided with slots j, which are engaged by the other tines of the forked levers D, so that when either of levers D is actuated the type-wheel A is not only rotated, as before described, and in some cases moved endwise, as before described, but is also thrown against the paper on the paperroll G to make the impression.

The paper-roll is moved endwise to space letters and'words by the pawl-nose 11, whose arm 121s aspring, and the feed-rack 6, whose teeth 7 are beveled on one side, so that when pawl 12 is rocked on its pivot 13 pawl-nose 11 is sprung sidewise. The feed motion of pawlnose 11 is imparted by rock-shaft K, on which is fast two arms 70, which carry a frame k, whose cross-bar I0 is actuated by each of the character-keys. The rock-shaft K also carries an arm 763, connected by link 712* with lever is", pivoted at is to the underside of the crossbar of frame g. Lever k is connected by link with pawl 12, so that the rocking of shaft K will swing pawl 12 in one direction, while the spring 14 will swing pawl 12 back, and

during this back stroke of pawl 12 nose 11 engages the rack 6 and feeds paper-roll B one step. The mask-plate 8 guides nose 11 sidewise with relation to rack 6 and its teeth 7. This mechanism is substantially the same as that shown in my application Serial No. 111,805, filed June 16, 1902.

The rock-shaft K is under the control of spacing-key k", as well as of the characterkeys B B.
