TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,200, dated March 26, 1889.

Application filed March 3l, 1888. Serial No. 269,129. (No model.)

To all whom it may concern:

Be it known that we, JACOB FELBEL and ANDREW W. STEIGER, citizens of the United States, and residents of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-IVriting Machines, of which the following is a speciiication.

Our invention relates more particularly to type-writing machines wherein the t-ype are impressed upon an hiking-surface and caused to print directly upon the paper, and wherein a center guide is employed to direct all the type exactly to the same point, so that a perfect alignmei'it in the printing may be obtained.

The invention has reference to a mode of mounting the type bar orcarrier; and it consists in pivoting it at one point to the free end of one pivoted link and at another point to the free end of another pivoted link, all as will be hereinafter more fully described, and set forth in the appended claims.

In the accompanying drawings, Figure l is a longitudinal vertical section of a type-writing machine embodying our invention, many of the necessary parts of the machine-such as feeding and spacing mechanisms, cbc.- heing omitted to simplify the view. Fig. 2 is a diagrammatical view of the type-carrier and its connections, and illustrating the movements of the type to and from the printingpoint. Fig. is a detail view of a modification.

In the several views the same parts will be found designated by the same letters of reference.

A is the base of the machine, at which are pivoted key-levers B B, that are adapted to be operated in the usual way by finger-keys C C, connected thereto.

I) represents (in dotted lines) the paperplaten or impression-roller. At the printingpoint e oi' the machine is arranged a typeguide, E, adapted to receive each type and cause it to print always at the impressionpoint.

F is a type-carrier, preferably composed of a bar, f, having at one end a laterally-projecting arm, f', to carry the type G, and at the other end a laterally-projecting arm, f2, bent in a direction opposite to the type-arm f The type-carrier is pivoted at K (at the junction of the bar f and arm f?) to one end of a link or lever, I-I, the other end of which is pivoted to the frame or some stationary part of the machine. Preferably we pivot all the links or levers I-I at one end upon a wire ring, I, which is supported from the base or some other iixed portion of the machine. In the drawings we have represented the ring or pivotal bearing I as supported by arms "i, branching from a pedestal or post, j, secured' to the base-plate of the machine. The typecarrier is also pivoted at K2 (at the rear end of the arm f2) to one end of a link, Ii, whose opposite end is pivoted to the frame or some stationary part of the machine. By preference we pivot all the links L upon a wire ring, N, which may be supported by arms n n/,proj ecting from the post or column The link II is made to serve as the operating-lever by providing it with an arm or projection, h, on that side of its pivotal support opposite to the pivotal connection with the carrierF. To this arm 71 pivoted a connecting-rod, O, the lower end of which is attached to a key-lever, as customary heretofore.

IVe preferably arrange the parts so that the type-arms f will normally lie in a horizontal planewith theirends projecting radially of the printing-point e and resting above the pivotal bearings of the type-carrier; but the parts may be differently proportioned and otherwise arranged, so that the normal position of the type-carrier may be different from what we have shown and just above given our preference to.

I) represents an in kin g-surface, so arranged that when the carriers are in their normal positions the faces of the type will touch the same. This inking-surface maybea circular pad of felt, which may be supplied with ink in any desired manner. The fulcrum-ringN is arranged centrally of the machine and the links L radiate outwardly and downwardly therefrom. The fulcrum ring or support I is arranged cxteriorly and concentrically of the fulcruni N, and the links Il extend therefrom in radial lines inwardly and downwardly toward the links L. The inking-pad is arranged above the fulcrum-ring I and between the latter and the platen. The type stand above the links ll and L and their pivotal supports or fnlerums and normally restI against the inking-pad.

The operation of the machine is as follows: llpon the depression of a key-lever, l, the rod is drawn down and the lever ll caused to turn on its bearing at l and swing upwardly. As the free end of the lever I l begins to rise the free end of the link L begins to descend, and the type-carrier connecting the two is slightly elevated and turned. As the vibration ol' the lever ll is continued theV link L begins to ascend, being carried up by the arm f2, and the type-carrier, moving about the pivots K K2, is finally caused to take a quarter-turn, the type (w traveling in the curved path marked .1f in the dii'awings. lVhen the type shall have arrived at the line y a further movement of the lever will cause thecarrier to move in a nearly vertical direction, as illustrated by the dotted line y, until the type G reaches the printingspoint, and, passing through the guide, strikes against the paper on the platen or roller. Upon' releasing the pressure on the Vlinger-key the typecarrier returns through the same path to its normal position, and its type is caused to strike against the hiking-surface and take a supply of ink for another impression.

A spring, R., may be provided at any suitable point to return the parts to their first positions.

By arranging the links to vibrate in oppo site directions we are enabled to nieve the type in the shortest possible path to reacht-he printing-point, and thus secure rapidity of action. In moving to the printin g-point each type takes two welldeiined paths, being carried first in substantially a horizontal direction to a point opposite the printing-surface, and then in a direction substantially at right angles to its Iirst path and perpendicular to the printing-snrface.

By varying the proportions of the several parts and the relative locations of their pivotal points the track traversed by the type may be changed, and we therefore do not desire to be confined to the proportions and arrangements of parts shown.

If desired,the inking-pad may be dispensed with and the usual ribbon interposed between the platen and the face of the type. So, also, may the eenterguide be omit-ted; but the best results can be obtained by its employment.

Instead of the key-levers B and connectin g-rods, some other connections may be provided between the finger-keys and the links II.

In lieu of lnoviding the link Il with an extension, 71, and vibrating it by pnllin g down, as illustrated at Figs. l and 2, the connecting rodA may he attached to the link II in front ol' its pivotal support and the link vibrated by an upward push, as shown in the modification exhibited at Fig. l

The gist of our invention rests in pivoting' the typebarrier to the free ends of twohnks, as H and L, which vibrate in opposite dll-ections. By this arrai'igement the type-face is turned while traveling te the pi'intingpoint, and then caused to inove in a straight line and strike perpendieularly to the platen, whereby the impression upon the paper may be made without any liability of lllurrlng. By this arrangement the type-face may also be presented perpendicularly to the inkmg pad or surface when used, and thus secure a uniform and perfect supply of ink.V

In practice we have constructed and pro portioned the parts substantially as shown, so that the type-:face is given a quarter-turn and presented perpendieularly to both the platen and the inking-pad, and the results have been most satisfactory as to the inkm g and printing mechanism. i

By our invention. a superior type-writing machine ot' small dimensions, light weight, and great durability and speed maybe made at a very low cost.

lVhat we claim as new, and d esirc to secure by Letters Patent, is-

il. In a type-writing machine, a typeearrier pivoted at one point to the free end of one pivoted link and at another point to the free end of another pivoted link, the said links being arranged to vibrate in opposite directions and cause the type to move in two well-defined paths, ii rst in substantially a horizontal direction radially inward to the common center and then substantially in a straight line and axially to the printingsurfaee, substantially as shown and described.

2. In a type-writing machine, the combination of a eentrallyar-ranged fulcru11i-support, a series of links, L, radiating therefrom, a concentric and extcriorly-arranged fnlcrumsupport, another series of links, Il, radiating therefrom toward thelinks L, and a series ol" type-carriers pivoted to .aid duplex series ofY radiating links Il and L, substantially as set forth.

3. In a type-writing machine, the combina tion of a series of pivoted links, H, extending inwardly and. down wardly, a series of links, L, pivoted nearer the center ot' the machine and extending outwardly and downwardly, and a series of typecarriers consisting of the armsf f f2, disposed as described, and pivoted to the free ends of the links Il and L at the points K K2, substantially as set forth.

+L. In a type-writing machine, thc con1blna tion of a series of inwardly-extending pivoted links, II, a platen above said links, a circular inkingsurface above said links and between them and the platen, a series of outwardly-extending pivoted links, L, and a series of typccarriers, each pivoted at two points to the free ends of a pair of said links, Il L, substantially as and for the purpose set forth.

5. In a type-writing machine, the combina- IOO IIO
