TYPE-WRITING MACHINE,

SPECIFICATION forming part 0t Letters Patent No. 430,773, dated. June 24, 1890.

Application filed February 10, 1890. Serial No. 339,768. (No model.) i

To all whom) it may concern:

Be it known that I, EMERY M. HAMILTON, of the city, county, and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of typewritin g machines having a vibratory typeactuating device bearing two or more printing-types in combination with a platen capable of moving in the machine to enable it to receive an impression from either of the printvice successively at the same printing-point thereon.

My invention consists, primarily, in the combination of a vibratory type-bar having two or more printing-types, with a platen adapted to be struck by said types successively on the same printing-line in positions corresponding to the number of said printing-types, which positions of the platen are in a line with each other at a right angle to the plane of the printlug-face of a type when in the act of striking the platen.

My invention consists, further, in a vibratory type-bar provided with two or more printing types, the planes of the printing-faces of which are at an angle to each other, whereby said types may strike successively on the same printing-line on a platen which is adapted to assume positions corresponding in number to the number of said printing-types in a line with each other at a right angle to the plane of the printing-face of a type when in the act of striking the platen; and my invention also consists in the combination of a series of vibratory type-bars adapted to strike at a common printing-point, and each having two or more printing-types, the planes of the printing-faces of which are at an angle one to another, with a platen adapted to vibrate 1n the direction substantially at a right angle to the plane or planes in which the type'bars are f ulcrumed.

Figure 1 is a central vertical section of a type-writing machine containing my lnvention. Fig. 2is a side elevation, partly in cross section, illustrating in detail a means for giving the platen its hereinafter-described movements. Figs. 3 and 4t are a plan and side elevation in detail of my type-bar. Fig. 5 is a plan of and illustrates devices which may be employed to vibrate the platen. Fig. 6 is a detail view of the platen and a type-bar, illustrating a modification of my invention. Fig. 7 is a plan of a series of type-bars having a common printing-point,- and each having two printing-types; and Fig. 8 is an enlarged plan in detail of the vibrated type-bar shown in Fig. '7.

In the machine illustrated in the drawings, the type-bars are shown at A, each carrying two printing-types and arranged radially in a series and fulcrumed in a common plane, and adapted to strike or print at a common printing-point, which is at the center of said series.

The form and arrangement of the series of type-bars may be varied from that illustrated, and any known and equivalent device may be substituted in place of the vibratory typebar to actuate the printing-types to strike or print at a point common to the type series without material variation from the essential features of my invention. The type-bars may be actuated by the usual key-levers, as at a, connected thereto'and furnished with fingerkeys, as at ct.

B is the platen, preferably in the form of a cylinder, and having the usual rotary movement on its axis in its supporting-carriage C, and with said carriage having the customary longitudinal movement across the machine during the operation of printing. The platen B is adapted to vibrate in the direction substantially at a right angle to the plane or planes in which are the fulcrums of the series of type-bars, so that it will assume two or more positions which will be in a line with each other at a right angle to the plane of the printing-face ot' a type when such type is in the act of striking and is in contact with the platen or the paper thereon to be printed upon. The vibration of the platen in the direction stated may be effected by causing the carriage C and its ways 0 to move at right angles to the plane of the type-bar fulcrums,

and these movements of the carriage and its ways and the supported platen may be effected by means of reciprocatory bars working in ways 0 and engaging the under side of the carriage-ways c at each end thereof, said bars being engaged by key-lever arms c ,which are operated through a connecting fulcrum-bar c by a key 0 which key may be located in the key-board of the machine. It should be understood, however, that I in no way limit myself to the use of the reciprocatory bars 0, arranged as described, as a means for giving to the platen the stated vibrations.

When a type-bar A is vibrated to strike the platen and a type carried by it is in the act of striking the platen, as. illustrated in Fig. 1, the described vibration of the platen will cause the platen to assume two or more positions which will be in a line with each other at a right angle to the plane of the printing-face of the type which is striking the platen and is in contact with the platen or the paper thereon to be printed upon. The platen is thus adapted to be struck successively on the same printing-line by the two or more types carried by each type-bar in positions which correspond in number to the num ber of the types on the type-bar, and which positions are, as stated, in a line with each other at a right angle to the plane of the printing-face of a type when in the act of striking said platen.

In constructing my improved type bar carrying two or more types I arrange the planes of the printing-faces of the several types at an angle one to another, as shown in Figs. 1, 3, and 4, where a type-bar having two printing-types is illustrated, or in Fig. 6, where a type-bar having three printing-types is shown. The planes of the printing-faces of said types on each type-bar are arranged at such an angle to each other successively that when the platen is vibrated, as described, to assume positions corresponding in number to the number of types on the type bar, which positions are in a line with each other at a right angle to the plane of the printingface of one of the types on the bar when in the act of striking the platen, the printingfaces of the other types on the type-bar will be adapted to respectively strike the platen on the same printing-line when the platen is inits other described positions. This is plainly illustrated in Figs. 1 and 6, the type-bar being shown striking the platen on the same printingline thereon, first with the type which is nearest the type-bar fulcrum, the platen being in one position, and then with the type or types beyond said first type on the type-bar, the platen being vibrated into positions corresponding to the number of said types, which positions are all in a line at a right angle to the plane of the printingface of a type when such type is in the act of striking the platen, and the type-bar being vibrated on its fulcrum to successively bring the printing-faces of the respective types to contact with the platen. It is evident that a type-bar may be thus constituted which, in combination with a platen having vibration in the direction specified, is adapted to print several characters or letters upon said platen on the same printing-line thereon.

I find it preferable to construct the typebar with two types, and to place upon one of the inclined faces, preferably the extreme end face, the upper-case or capital letter, .and upon the other of said inclined faces, preferably the one nearest the type-bar fulcrum, the lower-case or small letter, of the same alphabetical character. By this arrangement,.

when the platen is in normal position, as in Fig. 1, a small letter may be printed onthe platen by the type-bar, and when it is desired to print a capital letter the platen may be vibrated to a position in a line with its position when struck by the small-letter type at a right angle to the plane of the printingface of said small-letter type when in the act of striking, and a capital letter may then be printed on the platen by the other type on the type-bar on the same printing-line.

- I prefer to arrange the described type-bars radially in a circular series, as shown in Fig. 7, all adapted to strike at a common printingpoint, which is at the center of the series, and with the platen, as hereinbefore set forth, adapted to vibrate in the direction substantially ata right-angle to the plane or planes in which the type bars are fulcrumed. When thus arranged in a series, it is a feature of my invention that the types carried by each type-bar throughout the series are located, relatively to each other radially on their respective type-barsthat is to say, the types on each of all the type-bars of the series which, in vibrating to strike the platen, have their longitudinal axis at other than a right angle to the longitudinal axis of the platen are located on their respective typebars with the centers of their printing-faces in a line parallel to the planes through which their respective type-bars vibrate. This feature is illustrated in the vibrated type-bar shown in Fig. 7. It is apparent that the types which throughout the series of typebars are located on their respective type-bars nearest the type-bar fulcrums, and which, let us say, bear the lower-case or small letters of the alphabet, will be adapted to all strike upon the platen when in its normal position at a common printing-point, and that the types which throughout the series of typebars are located, as described, on their respective type-bars at the extremities thereof, and which, let us say, bear the upper-case or capital letters of the alphabet, will be adapted to all strike at the common printing-point and on the same printing-line upon the platen when the platen is vibrated in the direction substantially at right angles to the plane of the type-bar fulcrums to a position, as heretofore described, which is in a line with its first or normal position, at a right angle to the plane of the printing-face of a type when in the act of striking theplaten;

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a type writing machine, the combination of a vibratory type-bar having two or more printing-types with a platen adapted to be struck by said types successively on the same printing line in positions corresponding in number to the number of said types, which positions of the said platen are in a line with each other at a right angle to the plane of the printing-face of a type when in the act of striking the platen, substantially as set forth.
