T0 aZZ whom it may 0077106772 Be it known that I, FRANZ X. WAGNER, a citizen of the United States, residing at New York, in the county and State of New York,

have invented new and useful Improvements in Type\Vriters, of which the following is a specification.

This invention relates to certain new and useful improvements in type-writers; and it consists in the construction, arrangement, and combination of parts hereinafter fully described, and particularly pointed out in the claims.

' Similar letters indicate similar parts. i

The letter A designates the machine-frame, having bearings A for a horizontal shaft, 13, to which is fixed the type-segment G, as by 5 means of braces C. This segment is substantially rectangular in outline, as shown in Figs. 2 and 10, and is provided with two longitudinal rows of holes, a, inthe center thereof, op-

Fig. 2 is a detail longitudi- (N0 model.)

posite to which holes in a lower direction are situated the types D, the latter thus being in two sets, one to each row of holes. Each of said types is mounted face downward on one endofa flat spring, D, which thus forms a movable elastic support thereforyand the two sets of springs-concomitant to the sets of 5 typeseXtend in opposite directions toward the sides of the segment 0, where they are fastenednamely, on the lower surface of the segment. Under norirfal conditions the typesprings D lie fiat against the lower surface of the segment 0, as shown in Fig. 2, and in this manner the types are brought directly beneath the holes a, so that they may be readily depressed by a plunger or hammer, E, passing through the holes, for making the required impression. 111 the normal position of the type-segment O the hammer E is located at a point intermediate of the two sets of types, as shown in Fig. 2, and hence in order to bring any desired type of either set opposite to the hammer it is necessary to move the type-segment laterally in one or the other direction, as well as to rock the same on its axis, said lateral motion determining the set and said rocking motion the character of the type which is brought into alignment. For this purpose the shaft B, supporting the type-segment, is arranged to move longitudinally in its bearings and to receive a, compound longitudinal and rocking motion by the following mechanism:

Adjacent to the ends of the shaft B are situated sliding cams I), see Figs. 2 and 10,) which project downwardly from bolsters F G, extending transversely to said shaft, and each connecting with a corresponding bolster, F or G, inward on the machine, by means of end rods, F Said end or connecting rods, F, project beyond the bolsters F F G G at the ends, where they enter vertical slots 0, formed in fixed portions of the machine-frame, Fig. 2*, and under normal conditions the rods are held at the upper ends of said slots through the medium of springs d, which are arranged to act as supports for yokes d, engaging with the rods at the opposite ends. One spring 5 and yoke is used to each pair of rods F", and

' plained.

through the rods said springs practically support the bolsters F F G G. The bolsters F G, which are the outer members of the two pairs, are each provided at about the midlength with alaterally-projecting stud,e,which bears on the upper edge of a lever, H, while the inner bolsters, F G, are each provided with a corresponding stud, 0', bearing on the upper edge of a lever, H or I-P, one constituting a hammer-operating lever and the other a feed operating lever, as hereinafter ex- Said levers H H H H are adjacent tothe bolsters F F G G outward andinward 011 the machine, respectively, and are fixed to a rock-shaft, I, to move in unison with each other, this shaft being mounted in bearings A on the machine-frame, and being also utilized to carry the supporting-springs d of the bolsters. From each of the outer levers, H H, projects downwardly a sliding cam, b, which is opposite to the proper cam, b, of the bolsters, but under conditions is below it, and which is provided with a vertical slot, 11 Said outer or cam levers, H H, moreover, are subjected to the action of return-springs f one to each lever-having a tendency to raise the same, and thence to raise the levers H H and the bolsters F F G- G, with their connections.

Intermediate of each pair of bolsters F F G G is located a set of levers, J, which are hung to the sides of the machine-frame by pivots y, and alternately extend in opposite directions. These levers J rest at the free end on one or the other of the connecting-rods F F" of the respective pair of bolsters, and each is provided with a finger-key, J, which is marked with a letter or other character corresponding to one of the types of the type-segment, the number of levers in each set corresponding to the number of types in either set thereof. Said keys J are arranged in rows one abovethe other as shown, and each key-lever J is provided with a retur11-spring, J", which is connected to a suitable part of the frame.

- To the shaft 13 of the type-segment are secured, by radial arms 7L, rocking bars K' K one to each set of key-levers J -which are parallel to said shaft and at equal distances therefrom, but independent of each other, and which are adapted to enter gage-notches i in the lower edges of the key-levers. These notches t are located at different points in the key-levers J relatively to the segment-rocking bars K K, and one edge of each of the notches is beveled or inclined, as at i. lVhen the machine is at rest, the beveled edge 1) of said gagenotches of all the key-levers J is in the vertical plane of the rocking bars K K; and hence when either of the key-levers is depressed said edge of its notch comes in contact with either bar according to the set to which the depressed key-lever belongs, whereby the bar is guided into the notch of the lever and the type-segment is swung longitudinally to the proper position for bringing the desired type into alignment. Simultaneous with said longitudinal adjustment of the type-segment, the end of the depressed key-lever J acts on one of the connecting-rods F of either pair of bolsters to depress said rod, together with one end of the bolster, whereby the proper cam b of the bolster is brought incontact with one end of the shaft B of the type-segment, and this shaft is moved longitudinally, so as to adjust the segment laterally for bringing the desired set of types opposite to the hammer. WVhen either pair of bolsters, F F or G G, is depressed at one end, as stated, they swing on the connecting-rod which is at the other end thereof, and by the action of the proper studs 0 e of the bolsters both canrlevers H H are depressed simultaneous therewith, due to the connection of said levers with each other and with the levers H H through the rock-shaft, and the following condition is produced: In the longitudinal motion of the segment-shaft B the advancing end thereof enters the slot Z) in the cam b of either cam-lever, according to the direction of such motion, as shown in Fig. 10, while, when the parts are released and allowed to follow the action of the return-sprin gs f, the proper cam-lever acts on said shaft through its cam 11 to return the shaft to a normal position, the shaft being at the same time released by the acting cam b of the bolsters. The type-segment G is returned to a'normal position by its inherent gravity, and is held in that position by a locking-slide, L, Fig. 6, which is connected to the hammeropcrat ing lever H, and provided with a slot, L, of substantially T shape, whereby it engages one of the rocking bars K K of the segment. The type-hammer E is arranged in guides of the machine-frame, and receives a reciproeating motion at the proper intervals relatively to the adjustment of the type-segment G by the following mechanism: To the shank of said hammer E is connected the free end of a supporting-lever, N, (best seen in Figs. 7 and 8,) which has its fulcrum on a pivot, h,

and is located in the path of a tappet, N, projecting laterally from the hammer-operating lever H, so that when this lever is depressed by the action of one of the key-levers J of either set said tappet comes in contact with the hammer-supporting lever and depressesthe same, together with the hammer, as shown in Fig. 8. A spring, N, coiled on the shank of the hammer N, serves to raise the hammer when the parts are released; but in order to insure its upward movement a lifting-hook, N, is pivoted to a lug, N", on the lower edge of the hammer-supportinglever N, said hook thence extending through a slot, N, in said lever, and having its upper or free end provided with a sliding cam, N, which works in a slot, N of the machine-frame, so that when the parts are depressed said hook catches over the tappet N, as shown in Fig. 8, due to the action of the cam N, while, when the parts ascend, said tappet carries with it the hook,

together with the hammer-lever and hammer, said hook, however, gradually receding from the tappet as the cam ascends in its slot until the hook entirely clears the tappet, as shown in Fig. 7'. In this manner the hammer N is exposed to the action of the springs f of the camlevers, in addition to its own spring.

At a suitable point below the type-segment O is arranged the paper-carriage 0, which is guided on parallel rails O, and receives the usual intermittent motion by the following mechanism: To the free end of the feed-operating lever H is connected the corresponding end of a lever, P, which has its fulcrum on a pivot, i, and serves to connect with said operating-lever the free end of a lever,- P, the latter extending in a like direction to said operating'lever, but in an opposite direction to the intermediate lever. Said lever P bears at the free end on the upper endof'a vertical/reciprocating slide, 1?, (best seen in Fig. 3,) to which are connected escape-pawlsj 7c in proper relation to a toothed feed-wheel, P to alternately engage said wheel. The feed-wheel P" is mounted on a fixed shaft, Z, and contains a coiled spring, m, Figs. 1* and 3, it being hollow, one end of which spring is fixed to the shaft and the other end to the wheel in such a manner that the wheel has a tendency to turn in the direction of the arrow shown in Fig. 3. W'ith the feed-wheel P engages a rack, l, on the paper-carriage, and when the wheel is released it acts on said carriage through its spring at to move the carriage in a forward direction.. The vertical slide 1? is subjected to the action 'of a spring, 1), tending to force it upward, and under normal conditions the lower pawl, j, is thereby held in engagement with the feed-wheel l as shown in Fig. 3, while, when by the depression of either keylever J the slide is 'forced downward, said lower pawl is thrown out of gear, and the upper pawl, k, engages the wheel. As the lower pawhj, recedes from the feed-wheel,it is thrown back or in an opposite directicn to the movement of the paper-carriage to the extent of one tooth of said wheel by the action of a vceeding tooth of the feed-wheel, while the spring, q, and hence when the slide 1? is released and permitted to follow the action of its spring 2 said lower pawl engages a sucupper pawl disengages the wheel, thus allowing the latter to advance one tooth. The upper pawl, 75, forms part of a lever, P having its fulcrum on a pivot, 1', while the lower pawl, j, is on one end of a spindle, P, resting at or near the other end in a loop or eye, 8, which allows it to swing,and thereby accommodate itself to spring q is coiled on the spindle P", and fast tions on one side of the wheel, where the lower pawl, j, engages ordisengages said wheel in the rocking motion of the spindle P, and by this means the entrance of said pawl between the teeth is facilitated and insured, since if the pawl strikes either of the teeth it is guided to its place. The papercarriage O is provided. with a bed, 0 (best seen in Fig. 4-,) opposite to the type-hammer,

and also with feed-rollers O 0 ,for advancing the sheet of paper on thebed, said sheet entering between the rollers from a lower direction and over a shield, 0", on the carriage. The roller O is arranged in fixed hearings on the paper-carriage, while the roller 0 has its bearings in levers 0" each subjected to the action of a spring, 0, whereby said roller 0 is pressed against the roller 0'.

For the purpose of advancing the sheet of paper. motion is imparted to the roller 0 by the following mechanism: To the shaft of said roller is fixed a ratehet-wheel, Q, (see Figs. 3 and 12,) engaging with a spring pawl, which is hung to a swinging arm, Q, connecting with a supporting-lever, Q", which in turn connects with a hand-lever, Q. Fig. 4.) The supportinglever Q of the pawlarm has its fulcrum on a pivot, t, and engages the pawl-arm Q by means of a hook, t, Fig. 3, while it has a loop, it, for its connection with the hand-lever-Q". Said hand lever Q extends through said loop of the supporting-lever Q at one end, where it is subjected to the action ofa spring, a, having a tendency to retract the same, and it is provided on the other end with a handle, a, it having its fulcrum on a shaft, a intermediate of the ends. when the handlever Q is actuated in opposition to its spring, the lever Q shares its motion, and the pawl-arm Q is moved in the proper direction for turning the ratchet-wheel Q to the extent of one of its teeth by means of the pawl Q, whereby the roller 0' is properly advanced. The handlever Q extends transversely to the paper carriage O. and is bent at the outer-or. handle end, so that it can be conveniently taken hold of not only for turning the proper feed roller, but also for moving the paper-carriage back to the startingpoint.

Betweer the type-hammer and the bed 0 of the paper-Barriageis interposed the usual inking-ribbon, R, which is connected to reels 1% R, Figs. 2, 3, and 4, which alternately receive the proper rotary motion for advancing the ribbon by the following mechanism: To the ICO (Also seen in V shaft R of each reel is fixed a ratchet-wheel,

R Figs. 2 and at, which is adapted to engage with a pawl, It, hung to aperch, R, which is secured to two levers, R, both having their fulcra on a slide-rod, R Fig. 3, to which they are fixed, so that by moving this slide-rodlongitudinally in one or the other direction said levers and perch share its motion, and,either pawl is thrown in gear with its ratchetwvheel, while the other pawl is thrown out of gear. A spring-catch, It, Fig. 3, serves to retain the slide rod R in the desired positions by dropping into suitable notches therein. The perch is connected to one of the levers H H or both, by a pivoted link, 1), Figs. 1 and 7,which engages a loop, 'v,of the perch,'so that when the proper lever is depressed the perch shares its motion, and either pawl is caused to act on the proper ratchet-wheel to turn one of the reels. Each of the ratchet-wheels It is provided with a detent, R, which is hung to a fixed part of the frame and rests on a spur, w, of the proper pawl, so, that when the pawl is thrown out of gear said detent takes a corresponding position. The reels Rare keyed to their shafts R" to move longitudinally thereon, and they are inclosed within a sliding frame, S, which is arranged on said shafts, and to which is connected a thumb-screw, S, Fig. 4, in such a manner that the frame, together with the reels, may thereby be moved longitudinally on the shafts for shifting the inkingribbon laterally,

Said screw S turns on asuitable part of the machine-frame, and carries a notched wheel, S Figs. 4 and 11, engaging with a reversible spring-latch, S, which, when properly set, allows the screw to turn only in one direction, so that when the ribbon has been adjusted in cit-her direction for bringing a fresh portion thereof into alignment it cannot be moved in the opposite direction without first resetting the latch. Said, latch S", however, may be omitted, and other means than the screw may be used for adjusting the sliding frame S laterally to the ribbon.
