TYPE-WRITING MACHINE. Y

Specification of Letters Patent.

To all whom 'it rmay concern:

Be it known that I, EDWARD B. Hass, a citizen of the United States of America, revsiding in the borough of Manhattan, city, county, and State of New York, have invented certain Improvements in TypeWritb ing Machines, of which the following is a specification. j

This invention relates to adjustable ribbon vibrating mechanism capable of being set to bring' opposite the printing point any zone of a plural zone ribbon, and to eliminate the ribbon from the printing operation for stencil work.

In some respects this invention in part.

tion of this invention: Fig. 2, a detail view l showing the ribbon vibrator controlling link in a position different from that indicated in Fig. 1: Fig. 3, a like view showing the link in still another position Fig. 4, a detail view showlng a slightxnodication in construction: Fig. 5. a vien1 similaj,` to Fig. 1

showing the same adjustable means of determining the throw of the ribbon vibrator buta diti'erent means for actuating the vibrator, the adjustmentbeiug such as to bring the upper zone of the ribbon opposite the printing point: Fig. 6, a detail plan View showing the ribbon vibrator in section and its operating lever in plan: Fig. 7, a view similar to Fig. 5,showing the same constrnction, the ribbon stop devices being, However, in such position as to permit thc lower zone of a two zone ribbon to come opposite the printingr point: Fig. 8, is a detail front elevation showing the front plate in which are mounted the ribbon adjusting push-pin buttons marked respectively i Bottom Stencil Top Fig. 9. a view similar to Fig. 7 showing the parts adjusted for stencil work; and Fig. 10, a detail sectional view showing a forni of detent device for holding the ribbon vibratorstop devices in 'any position to which they may be adjusted.

In the several figures l indicates the platen, 9, the platen carriage running in ball earings on a vertically shiftable carriage frame 3. On a centrally disposed projection 4 extending downwardlv from the carriage 3 is pivoted at 5, a bell crank lever whose horizontally disposed forwardlyr projecting arm (i has hingen to its front end a vertically disposed link 7 (Fig. 1) to which is pinned or hinged at 8 the verticalljY movable ribbon guide or vibrator 9.

10 indicates an ordinary stationary center guide for the type bar heads. rIhe shorter downwardly extending arm 11 of said bell crank has at its end a lateral projection 12. In rear of the axis 5, the crank has a horizontal projection 13 adapted to contact with an adjustable headed stop screw 1l Working in a threaded aperture in the bottom of the carriage 3. The ribbon vibrating bell crank G. 11, is actuated bv a horizontally disposed link l suspended by parallel links 1G, 17. The link 15 is centrall)- enlarged and eut out so that one side wall of the opening has three surfaces 1S. 19, Q0. located at diticrent distances from the respective ends of the link and adapted to engage the lateral projection l2 in the short arm 11 of the ribbon guide actuating bell crank. The lin'k 1T is suspended from a pivotal mounting 2l on a projection on the under face of the carriage 3 and has a forward horizontal prlojection 22 Whose end is connected b v a coiled spring with th'c short arm 11 nt the bell crank. The link 1G that .supports tbc from end of the horizontal link l5 is capable of vertical movement such as lo bring at will either surface 1S, 19 or 2O opposite lateral projection 1:? of the bell crank. lt' a substantially uniformi extent of horizontal movement beimparted to link 15. the extent to which the ribbon vibrator is moved ill depend upon whether the surface 1S or '20 engages the projection 12 on thebell crank. The surface 19 ma)v be at such distance from the projection 1Q when the normal extent of movement is imparted to link 15 that there will be no actuation of the ribbon guide. The reaction of spring 23 tends to hold the ribbon guide down and the .projection 13 ou the bell crank in Contact with the stop screw 14 thereby determining the ratentedvneb. s, 1910.A

normal lowermost position of the ribbon vibrator.

The drawings indicate a key lever machine. 2i beingr one of the key levers pivoted at its rear end and having its upturncd front end equipped with the usual finger piece QG. A link QT extending up from the key lever engages, between its ends, a horif zontally disposed link '28 whose front end is pivoted in a tixed post or support Jointed to the rear end of linlY :2S is a link hinged at its rear end to the heel of its type bar 31. 'hen the key lever is depressed the type bar will be thrown to the printing point.

is au ordinary universal bar disposed below the key levers and carried in the ends of forwardly extending universal bar arms 33 fast upon a rock shaft 34 and havingr upwardly extending arms 35 to which are applied coiled universal bar springs 36. At the center of the machine there is a similar universal har arm 3T also fast on the rock shaft 341 and projecting as at 3S in rear thereof. Pivotcd at 39 upon such projeetion is an upwardly extending lever arm #1-5 naving a short forwardly extending arm 40 with a part 41 extending under thc universal bar arm 37 and provided with an adjusting screw 42 bearing against the bottom of arm 3i'. The side of the arm 4() has a slot 43 to receive a headed clamp bolt 44 that screws into the side of the arm 3T. This construction affords a ready and accurate means of adjustment of position of the upwardly extending lever arm 45, The extreme upper end 46 of this lever arm is adapted to operate upon a lateral projection i7 on the side of link 15. 7When a key lever is depressed the universal bar is carried down and the upwardly extending lever arm is thrown forward, its upper end 1G contacting with projection 47 and carrying the link 15 forward. If the adjustment be such as is shown in F ig. 2, surface 2O of' the link 15 will operate to actuate the bell crank (3, 11, and there will be imparted to the ribbon guide a definite extent of motion such as to bring opposite the printing point the upper zone of the ribbon. If, as in Fig. 3. the surface 1S is opposite the projection 12 thcn obviously a greater extent of movement will be imparted to the ribbon guide to bring 'the lower zone of a double zone ribbon opposite the printing point. If surface 1f) of the link is opposite the projection 1:?. there need not be any movement of the link 15 to actuate the bell crank (E, 11 and consequently the ribb n vibrator will not 6o be moved from its no1 aal inoperative position.

There are provided adjustable stop devices to definitely and positively limit the upward movement of the vibrator, and co-incident with the adjustment of such stop devices the link 16 is adjusted vertically to determine the relation of link 15 to projection 12 on arm` 11 of the ribbon vibrator bell crank. There is a transverse rock shaft 4S mounted in bearings on the under side of carriage At its end adjacent the left hand side of the machine it has a projection 49 to which is connected a link 5() extending forward hori- -zontally and jointed at its front end to a vertically disposed lever 51 pivoted intermediate its ends at 52. Respectively above and below the pivot 52 there are jointed to the lever 51 horizontally disposed push pins, 53, 5.1L, mounted in a plate 55 located in the frontplate of the machine. As seen in Fig. 8, these push pins are equi ped with ringer buttons bearing respective j' the words Bottom and Top i. Intermediate these two push pins there is a third one 5G haviner a button or finger piece marked Stencil The pin 56 carries on its inner end a plate 57 with a horizontal slot embracing`the pivot 52 and having applied to it a coiled spring 58 tending normally to retract it.` Projecting laterally from the plate 5T respectively above and below the pivot are

pins

59, 60 which, when the push pin 5G is pressed inwardly, brings the lever 5I into vertical position.

The inner end of transverse shaft 48 is at about the center of the machine and on it is a camlike stop plate (31 having two surfaces of ('{iiferent radius marked respectively a, b, each adapted to cooperate with a projection (3 on the upper edge of the arm 6 of therribbon vibrator bell crank lever. adjacent the inner end of the transverse rock shaft L18 is a rearwardly extending projection 62 to which is pivoted the link 16 that supports the front end of the horizontally disposed link 15. The parts are all so related and proportioned that the stop surfaces a, are by movement of the rock shaft-l brought respectively into proper posi` tion to limit movement of arm 6 whenthe corresponding respective surfaces 18. 20, of link 15 are active. Thus, for stencil work the button marked Stencil is pushed in' and the parts will be brought into the position indicated in Figs. 1 and 9. In this position a stop for the bell crank is not necessary because the surface 19 of link 15 is so distant from projection 122 that there will be no contact when link 15 moved endwise. If the push button marked i Bottom be pressed inwardly the upper end of lever 51 will be rocked rearwardly and link 15 will be adjusted to the position shown in Fig. 3. If the push pin marked Top be pressed inwardly, the link will be adjusted to the posi tion shown in Fig. 2. 4 lCo-incidentally with any such adjustment of the bottom and top push pins, the proper stop surface a, or b will be brought into position to coperate with the projection 6 on the arm 6 of Also ator the bell crank lever. When printing is to be. done from the lower zone of the ribbon, stop surface is sei to limit the movement of the vibrator, and when the tipper zone of the ribbon is to be used the stop surface a is pressed positively against the stop surface u or 7;. The saine maiY be truc when the atl- ]ustment is for stencil work.

It is desirable that there shall be soine form of detent device to hold roek shaft -l in either of the three positions to vvhicli it i may be adjusted. Such a device ot' .suitable character is shoivn iii the detail sectional view, Fig. 10mhielt is a section taken in rear ot' the stop plate Gl as vieived in Figs. l and ing means it is of course necessiry that there should be a stop surface for stencil work and therefore the surface c, of greater radius than a or b, is provided and it is brought into operative position when the center, or stencil, push pin is pressed inward. f

In all the main figures of the drawing it is contemplated that the carriage shall shift. In Fig. 7, d, e indicate the now well known shift links or levers to be appropriately operated from a shift key as is well understood. The stop selecting devices are on the frame and the stop' devices, the ribbon vibrator, bell crank, and link lrare carried by the shifting carriage.
