HENRY w; minim, OF SYRACUSE, NEW YORK, sssronon ro THE ONAROH TYPEWRITER' genres-Y, OF sra reusn, NEW YORK, A CORPORATION OF NEW YORK.-

To all-"whom it may om 1 Be it known tlfiat'I, HENRY W. Mnfu'zrr'r, a citizen of the United'States, and resident-ofsyracusef in the couhtybf Onondaga and State ofjNew York, have in:

'vent'e' d certaimnew and useful Improvements in Type WritingMachines, of which the following is a ism" therefor? Trabjecmr iny in'ventioii is to provide simple,

cheap andefli'e'ient automatically actuated printing upoirithiechanism, which is particularly adapted for so 'cal ltl' 1 visible writin g machines wherein ordinatilyjth e ribbon is vibrated t0 and from the printing point at each printing operation.

mechanism and certain of the associated parts.

Tothes'e and other ends which will hereinafter appear, rny'invention c'onsistsin the features of construe tmmtmngement of parts and combinations of de-' vices to 'be'hereinafter explained and more particularly pointed out in the appended claims.

Inthe accompanying drawings, l igure'l is a front elevatioii showing the upper portion of a typewriting machine, with my invention applicd thercto. Fig. 2 is a vertical central longitudinal sectional view taken from front to rear of the machine. Fig. 3 is an' enlar'gd detail vertical sectional view of the indicating Fig. 4 is a plan view of the same, the top plate of the machine being sectioned away. Fig. 5 is an enlarged detail rear perspective view of the indicator. Fig. 6 is an enlarged detail rear view of the ribbon vibrator.

The base '1' of themachinc is provided with corner posts 2 supporting a top plate 3, on which a suitable carrittgefnot shown) is adapted to travel from side to side of the machine The carriage supports the usual cylindrical platen 4. aud carries a feed rack 5 withi which feed dogs (3 cooperate to afford a step by-step feed of thc 'carriage from right to left. The feed dogs are carried" by the-usual dog rocker 7, which is pivoted to a suitable bracket supported by the frame of the machine'and has a forwardly extending arm 8 to which a depending link 9 is connected. The lower end of the link 9 is pivotedat 10 to a rearwardly extending arm 11 of a universal bar frame pivoted at 12 to the base of themachine. Key levers 13 are provided with finger keys 14' and are fulcrumed against a fulcrum plate 15 supported" by the base of the machine. Each key lever is restored to its normal position by a spring 16 connected at its forward free end to a strap or link 17 that is pivoted at 1'8 to'the associated key lever. Each key lever has a sub-lever 19 pivoted thereto at 20, the

- lowei'endsof the sub-levers being slotted at 21 for cooperationwith a fixed fulcrum rod 22 that extends 'beneaththe key levers'and is secured to the base of the Specification or Letters Patent. Application filed April 24. 1905. Serial No. 257.18

machine. The upper end of each sub-lever is ay oted at 23 to a link 24, the forward end of which is pivotcd at 25to a type bar 26, the latter being pivoted on a pivot wire 27 carried by a segment 28. A depression of each key lever effects a l upwardly and rearwaxdly swinging movement of the associated type bar to impact with the platen'at the printing, point a. A'universal bar 29 is secured to the.universal bar frame and extends beneath the various key levers sothat a de pression of any key lever will effect a downward pull on the link 9 so as to produce a movement of the dog rocker against the tension of its restoring spring 30, thereby affording a step-by-step feed movement of the carriage as the key lovers are actuated. The arm 11 also has an i'i r'fwardly extending link 31 pivotedthereto, theupper end of said link being pivoted at 32 to a forwardly extending vibrator actuating lever 33 of the first order, pivoted at 34 to a stud 35 that extends down I wardly from the top plate 3 of the machine. Theforward end of this actuating lever 33 is bifurcated at 36 p to receivev the pivot pin 37 of a ribbon viblator 38.

This ribbon vibrator may be of any suitable constru ction and in the present instance is illustrated as a bifurcated vibrator, the inner edges 39 of the bifurcated portion being received in grooves {10 in a guide 41 that may be secured to the top plate of the machine by screws 42. The guide is bifurcated as shown in Fig. 1

to, provide upright arms, in theouter sides of'whieh are the guiding grooves 40 and the types impactwith the ribbon 43 between the guide arms. The ribbon isv received within guide openings 44 in the vibrator and is fed ireclytherethrough from one ribbon spool 45 to another by any suitable means. The mechanism thus far described is or may be of the usual construction such as that employed, for instance, in tlie Monarch typewriting machine.

A second set of guide grooves 46 is provided in the guide arms, said grooves being parallel to the grooves 40 and adapted to receive the upright guide arms or members 47, 48, of an indicator, which is illustrated in detail in Fig. 0. The guide arms 47 and 48 are connected by a cross piece 49 that has anupwardly projecting printing point-indicator 50 extending therefrom. The lowcr'end of the arm 47 extends inwardly and is provided with a pivot pin 51 similar to the pivot pin 37 of the ribbon vibrator. This pivot pin 51 is adapted to be received in'a' bifurcation 52 in a lever 53 of the thirdorder pivoted at 54 to a depending stud 55, extending from the top plate of themachinc. beyond its pivot so as to forman extension 5'6 against which one end of an expansion spring 57 bears, the up per end of the spring being adaptedtoheanagaiust the top plate of the machine, thus tending to elevate the forward end of the lever 53 and thprinting point/indicator carried thereby. A 'bin fiR extends laterally The lever extends 9,, season from the lever 53 and into the path of the ribbon vibrator actuating lever 33, so that a downward movement ofthe'rear end of the lever 33 during the elevation of the ribbon vibrator, will cause the forward end of the lever 53 to be depressed, thus effecting a down ward movement of the printing point indicator. In the normal position of the parts the printing point indicator is in an elevated position so as to register with the bottom of a letter imprinted at the printing point,.as indicated in Fig. 1; whereas the ribbonvibrator is in the lowered position, thus maintaining the ribbon away from the printing point to expose the last written 1etter. The, construction is such that a depression of a; finger key will effect an upward movement of the ribbon vibrator so as to inter-pose the ribbon in the path of the type which is being moved to the printing position',' and will simultaneouslywithdraw the printing point indicator from the indicating position so 'that it will not interfere with the imprinting of a character at the printing point. When pressure on the key is re; leased, the indicator will be automatically moved up to the indicating-position and the ribbon vibrator will be lowered so as to expose the last Written character. It will be observed that by my invention I have provided a simple, cheapand efficient printing point indicator which may be readily applied toexisting forms of typewriting machines without material modification of such machines, and that in the'normal position of the partsfthe indicator will always be in the indicating position, but will nevertheless be automatically with-' drawn from the indicating positionduring the printing operation; that the ribbon vibrator and indicator move verti cally in opposite directions in their movements from and tothe normal positions; that the ribbon vibrator and indicator are arranged side by side in parallel vertical planes and codperate with actuatinglevers which are Likewise arranged side by side in vertical planes that extend fore and aft of the machine; and that the movement of the indictor to and from the indicating position is controlled by the means for actuating the ribbon vibrator or by the leyer 33,

It should be understood that various changes may be made without departing from the spirit of my invention and that the invention may be applied to various forms of typewriting machines, and more especially to various forms of so called visible writing machines, and that various ghangcs and modifications may be made to adapt the invention to different forms of machines.
