SPECIFICATION forming part of Letters Patent No. 464,902', dated December 8, 1891.

Application filed January 29, 1889. Serial No. 297,943. (No model.)

T all whom it may concern:

Be it known that I, GHRIsTOPHER LATHAM SHOLES, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Type-Vriting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to type-writing ma- 1o chines; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to theaccompanying drawings and subsequently claimed.

In the drawings, Figure l represents a vertical longitudinal section of a type-writer constructed according to my invention, the section being taken on line l l of Fig. 5; Fig. 2, a rear elevation illustrating the paper-oarriage, certain of the parts being broken away 5 Fig. 3, a side elevation of the machine with parts broken away 3 Fig. 4, a detail sectional view taken on line 4 et of Fig. 3. Fig. 5, a de'- tail front elevation havin'g certain of the parts broken away; Fig. 6, a detail rear view illustrating atype-rod and its actuating mechanism in their normalV position, Fig. 7, a vertical transverse section of Fig. "6; Fig. 8, a detail rear view illustrating a type-rod and its actuating mechanism in the position they assume when a lever corresponding therewith has been partially depressed; Fig. 9, a vertical transverse section illustrating a type-rod audits actuating mechanism in the position they assume when the corresponding lever has been fully depressedj Fig. 10, a rear elevation of what is shown by Fig. 9, and Fig. ll a horizontal section of the parts shown in Fig. l0. l

Referring by letter to the drawings, A represents the base of my machine, and secured to this base are standards B, united by tracks b for anti-'friction rollers c on a spring-controlled carriage C, the latter being provided with a rack cl, alternately engaged by pawls e fon the upper end of an arm g, that is fast on a rod D, having bearings hon said standards. lonnected to the rod I) are the ends of a bail E, that rests on spring-controlled le- 5o vers F G, thelevers F (only one of which' is shown) being provided with vert-ical stems l, that connect with a spacing-bar H. 'The carriage and its escapement mechanism above described are not materially different from what are common in some other type-writers, 5 5 and therefore I shall make no specific claims to the same. f

The carriage C is provided with guides for vertical rods I, provided at their upper ends with bearings lt for the journals of a 6o' cylindrical and intermittently-rotated platen J, so common in a variety ot' type-writers now in use that a detailed description of the parts by which it is actuated is not deemed necessary in this application, while at the same time a paper-guide K, also common in this class of devices, is arranged on said rods to move with the platen when the latter is adj usted in a vertical direction, as will be hereinafter more fully described.

The rods I are united by abrace L, having a depending bracket M, and to the latter is j ournaled an anti-friction roller 7n', that is normally out of contact with a track N, the ends of the latter being connectedby brackf ets m with a rod O, having its bearings in angular standards?, arranged in 4pairs and secured to the base A. Fast to one end of the rod O is a lever Q, and pivotally connected to this lever is a T-shaped link R, that en- 8o gages the slotted ends n of leversl S T, loose 011 another rod U, having its bearings in the angular standards P, this construction. being best illustrated in Figs. 3 and 4..

Although the levers S T have the same fulcrum, it is intended that one of them shall have a greater lift than the other, and to this end I provide the adjacent one of the angular standards I) with bearings p o' for screws s t, the lower ends o f the latter being at dit- 9o ferent elevations to serve as stops for said levers.

Vhen the lever S is actuated, the track N will be brought into contact with the anti-friction roller 7o and the platen J will be'raised a 95 certain distance; but when the lever T is actuated a greater elevation of said platen will be accomplished, the purpose of this vertical adjustment being hereinafter described. Then the platen is raised and held up out of its nor- 1 oc mal position, the anti-friction roller 71: runs on the track N and thereby compensates for the leverage of said platen on its carriage C.

An inking-ribbon V is arranged to pass the printing-point of the machine; but as there are a variety of ribbon-actuating mechanisms adaptable to said machine I deem it unnecessary to particularly illustrate and describe vany one of them in this specification.

The vertical portions of each pair of the angular standards P are united by braces u and diagonal plates W, the latter being provided with a series of cam-slots fu, each of which extends in ahorizontal and vertical direction. The slots, as shown, are L-shaped, as it is essential to the operation of a machine constructed according to my invention that said slots shall extend in both a horizontal and vertical direction.

The rear sides of the diagonal plates WV are provided with a series of guides w for vertical links X, that connect with the levers G, and are individually provided with diagonal camslots these slots being arranged to cross the horizontal portions of the slots i; in said diagonal plates when the links are in their normal position, as is best illustrated in Fig. 6.

A series of rods Y have their bearings in each pair of the vertical standards P and terminate at their inner ends in right-angular extensions Z, the latter being the type-bars. and the type-bars in each series are arranged to stand one behind the other, as best illustrated in Figs. l and 3. The rods Y are provided with fingers y, that engage the slots fu in the diagonal plates IV' and vertical links X, whereby an upward movement of any one of the latter will cause its accompanying rod to move horizontally and then partially rotate in its bearings to bring its angular eX- tension or type-bar Z to the printing-point, as will be hereinafter more fully described with particularreference to the enlarged detail views, Figs. 6 to 11, inclusive.

As shown by Figs. 6 and 7, the parts are in their normal position, the finger y on the rod Y being at the highest point in the slot a: in the link X. Now by a depression of the corresponding lever G the link X will be moved up and its slot 0c will push on the linger y to thereby impart a horizontal sliding movement to the rod Y, this movement being for a distance equal to the horizontal portion of slot v in the adjacent diagonal plate WV. By the time this horizontal sliding movement of the rodYis effected the finger y will be at the lowest point of the slot m in the link X and in the vertical portion of the slot c in the plate, as illustrated by Fig. S. Now the continued upward movement of the link X will draw on the inger y and cause it to move in the vertical portion of the slot o in tne plate W,

, whereby the rod Y is partially rotated in its bearings, and thus the angular extension Z or type-bar on said rod is brought to the printing-point.

In the machine shown in the drawings each sarily describes a separate arc when moved toward the printing-point.

VVhe'n the platen .I is init-s normal position with relation to the carriage C, the `lower characters on the type-bars Z will strike the printing-point; butif the lever S be depressed and held down the said platen will be elevated to bring the printing-point in position with relation to the middle characters'on said typebars, while a depression on the lever T will bring said printing-point in position to be struck by the upper series of characters, the actuating-levers G being provided with indicator-buttons, as is common in machines belonging to the class tao which my invention relates.

The number of characters on the type-bars may be multiplied so that more than three rows of such characters will be presented, and in such an instance the platen wopld necessarily be capable of.more adjustments -at right angles to the travel of its carriage than has been shown anddescribed.

By'the construction above described I provide a type writer of practical character wherein there is a positive adjustment and action ofthe type-bars and lconsequent perfect alignment of the printed characters, while at the same time the result of the work is always in sight of the operator. Both' of these features are of great importance,.be cause more or Vless frequent adj ustments' of the type-bars to preserve a good alignment is obviated and the lifting of the paper-carriage to view the work 'in progress 'is avoided, thereby effecting a saving in timeand annoyance to the operator.

Another advantage of my machine lies in the fact that there are no delicate mechanisms, and consequently said machine is not liable to get out of order from hard usage.

In a divisional application, Serial N o. 401,493, is claimed the mechanism for actuating the type-levers and complemental parts. Hence I make no claim to said mechanism in this specification.

Having'thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1. In a type-writer, the combination of a reciprocating carriage, a platen-frame loosely mounted thereon and provided with a depending portion, a lifting-frame for contact with the depending portion of the vplatenframe, and a lever mechanism for actuating the lifting-frame, substantially as set forth.

2. In a type-writer, the combination of a reciprocating carriage, a platen-frame loosely mounted thereon and provided with'a depending portion, a lifting-frame for contact with the depending portion of the platenframe, a lever connected to the lifting-frame,

a T-coupling pivoted to the lever, and slotted IOO IIO

mounted thereon, an anti-friction roller suspended from said frame, a track for the roller, 15 and a lever mechanism for lifting the track, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee. in the county of Milwaukeeand State of Viszo cousin, in the presence of two Witnesses.
