TYPE-WRITING MACHIN.

SPECIFICATION forming part of Letters Patent No. 385,122, dated October 22, 1901. Applicant inta reentry 11,1901. serai 1111.46.858. (No modem .To ally/71,0771, it 11i/ty concern:

Be it known that I, JACOB FELBEL, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This application relates to the type-actions and caseshift mechanisms of writing-machines.

The main object of the invention is to provide simple and efficient connections between the type-bars and the keys in machines in which the type-bars are shifted from lowercase to upper-case position.

The invention consists in certain combinations of devices, features of construction, and arrangements ofY parts, all as will be hereinafter fully set forth, and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a vertical section, taken longitudinally, of a front-strike writing-machine constructed in accordance with my improvements, showing the parts in normal position. Fig. 2 is a view similar to Fig. 1, but showing the system of type-bars as shifted to upper-case position and one of the type-bars as in printing position. Fig. 3 is a front sectional View taken just forwardly of the type-bar segment at about the line X X of Fig. 1.` Fig. 4 isa diagram illustrating the fanning or diverging arrangement of the key-bearing bell-levers. Figs. 5 and 6 are views of modifications.V

In the several views certain parts are omitted and others broken away to disclose the invention more clearly.

Similar parts are designated by similar numerals of reference.

The machine-frame comprises a base 1, corner-posts 2, and top plate 3. Keys 4 are borne by the forward ends of rearwardly-extending horizontal levers or arms 5, which are pivotedat their rear upon a transverse horizontal fulcrum-rod 6 and have at their rear ends upwardly-directed levers or arms 7, the latter, together with the arms 5, forminga system ofv bell-levers. These levers are spaced along the fulcrum-rod 6 by collars 8. To the tip of each arm 7 is'pivoted the forward end of a rearwardly-extending link 9, whereby said arm is connected to an upwardly-'directed rocker arm or lever 10 of the third order. These levers or actuators 10Vare pivoted at their lower ends upon a horizontal fulcrumrod 11 and provided with spacing-collars 12'. The upper ends of the levers 10, which, it will be noted, extend longitudinally of the arms or levers 7, are connected by forwardly-extending links 13 to the downwardly-extending short arms of rearwardly-striking radial type-bars 14, arranged over the key-bearing arms 5 and pivoted at their rear ends upon a curved fulcrum-wire 15, seated in a slot 16, formed in a segment 17, the latter being provided with radial slots 18, in which the typebar hubs work. The type ends of the bars rest upon a cushion 19,which is supported by a forwardly-extending horizontal arm or frame 20, connected to the segment through downwardly-projecting bars 39 thereof. The system of vertical arms 7 is preferably of substantially the same width as the system of sublevers 10 and the system of type-bars 14, but of less width than the keyboard. vHence thearms 5 fan out or diverge forwardly from the rod 6 to the keyboard, as will be understood from Fig. 4, which Villustrates the extreme'right and left and central arms 5.

Beneath the system of key-levers 5 extends a transverse universal bar 21, which is hung by links 22 upon a pair of horizontal rockerarms 2 3, mounted upon a rock-shaf t 24, which is journaled upon opposite lugs 25, cast upon the base, said rock-shaft being provided with a returning-spring 26. Extending upwardly from said shaft is a rocker-arm 27, carrying at its upper end a feeding-dog 28 and a detent-dog 29, said dogs coperating with escapelnent-wheel 30, which is mounted upon a bracket 31 and connected to a pinion 32. With the pinion meshes a rack 33, secured upon a carriage 34, which slides upon rails 35 and affords a traveling support for a platen 36. Said carriage is propelled by a springbarrel 37, which is connected thereto by a strap 37a.

Upon depression of any key its bell-lever is Vibrated upon the rod 6, the upright arm 7 rocking forwardly and by means of the link 9 causing the sublever 10 also to rock forwardly, thus pushing upon the link 13 and swinging the type-bar up to print a lowerssA IOO

case letter. At the same time the universal bar 2l is carried by the horizontal arm 5 of the bell-lever and through the links 22, arms 23, and upright rocker-arm 27 the feedingdog 2S is moved out of engagementand the detent-dog 29 into engagement with the escapement-wheel. Upon reliefof the key from pressure the dog-rocker is returned to normal position by the reaction of the spring 26 and in the usual manner the carriage is permitted to advance one step under the tension of the propelling-spring 37. At the same time the type bar and key return to normal position, partly under the influence of the dog-rocker spring 26 and partly by reason of the weight of the type-bar and key-lever, although, if desired, the latter may be provided with an individual returning-spring 38.

The segment 17 is provided at each end with integral downwardly-extending bars 39, which by means of perforated ears 40 may slide in an up-and-down direction upon vertical guide-rods 4l, which are secured at their upper ends in bosses 42, formed upon the under side of the top plate and at their lower endsin inwardly-extending arms 43,cast upon the base, said arms normally sustaining the weight of the described frame 17 39 and the parts thereon and said bosses limiting the upward movements of the shifting frame. Extending rearwardly from the sliding arms 39 is a pair of horizontal arms 44, between which the sublevers 10 are confined and upon which the sublever fulcrum-rod 11 is mounted, so that when the segment is lifted said sublevers may rise bodily therewith. The lower ends of the sliding arms 39 are provided with screw-studs 45, with which engage the slotted rear ends of a pair of horizontal arms 46, which are fastened, by means of collars 47 and set-screws 48, upon a horizontal transverse rock-shaft 49, the latter being rocked by means of a forwardly-extending arm 50, provided with a shift-key 51. Upon depression of said key the shaft 49 is rocked and the rear ends of the arms 46 elevated, thereby pushingupwardlytheshiftingframe,together with the type-bars carried thereon, the sublevers 10, and the links 13. lVhile the shiftkey 51 is held down any of the type-keys 4 may be depressed and the capital types upon their connected type-bar caused to strike the platen, as illustrated at Fig. 2. Upon the relief of the shift-key 5l from pressure the shifting frame, type-bars, links 13, and sublevers 10 return by gravity to normal position'.

During the shifting movements of the typebars away from the key-levers the links 9 vibrate, their rear ends being carried upwardly by the sublevers 10, while their forward ends pivot on their' key-levers 7, which relnain motionless. Said links may, however, operate the type-bars at either shift position of the latter.

Since the type-bars, owing to their groupcenter, are supported at different heights, the forward ends of the type-bar links 13 are also necessarily arranged at differentheights, and, if desired, the sublevers 10 may be made of gradually-increasing lengths, so as to support the rear ends of these links at gradually-increasing heights, whereby said links may be supported in substantial parallelism. The upright arms 7 of the key-levers may also be made of different lengths, it being desirable, however, that the links 9 connect the arms 7 to the sublevers 10 at such points that the dip of the keys lnay be uniform for the entire keyboard. To this end the rear attachingpoints of said links may be gradually raised as the sides of the machine are approached, thereby compensating for the increasing length of the levers 10. At Fig. 3 the arms 7 and sublevers 10 are indicated by dotted lines, the arms 7 at the left-hand and the sublevers at the right-hand side of the machine being omitted. Thus it will be seen that the keys are connected to the type-bars by simple and freely-operating devices, while the type-bars are enabled to be readily shifted in order to bring the capital types to printing position.

Referring to Fig. 5, the shifting sublevers or type-bar actuators l0 are connected by rearwardly-extending pull-rods 52 to the upper ends of vertical levers 53, which are pivoted at 54 directly upon horizontal key-levers 55 of the second order, the latter being fulcrumed at their rear ends upon a fixed transverse rod 56. The levers 53 extend forwardly below the key-levers 55 and engage at their lower forked ends 57 a fixed transverse rod 58. Upon the depression of a key the lever 55 vibrates downwardly upon the pivot 56, while the upright lever 53 by reason of its engagement with the fixed rod 57 is caused to swing rearwardly, and thus through the links 52 pulls the actuator 10 rearwardly upon its pivot, which through the link 13 swings the type-bar up to print.

In the modification shown at Fig. 6 the vertically-shifting type-bar actuators are in the form of slides, each slide comprising both a horizontal arm 59, which has bearings 60 upon a shifting frame, and also an integral upright arm 6l, which is connected by a link 52 to the bell-crank 53 and also by a link 13 to the type-bar 14. Upon the depression of a key the bell-crank 53 is swung rearwardly, and by means of the link 52 the actuator 59 6l is caused to slide rearwardly, thereby through the link 13 pulling the type-bar up to print.

The herein-described connections from the ltypes to the keys may be employed whether `or not the types are shifted, or sublevers or actuators of other design and differently connected to the type-bars may be mounted to shift therewith while connected to the keys.

Various other changes may be made within the scope of the invention.
