To all lwhom it may concern:

Be it known that I, FRANK A. YOUNG, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification. y

My inventionrelates to printing point indicators and more particularly to printing point indicators for visible writing machines.

The object of my invention is to provide simple and efficient printingpoint indicating mechanism which is automatically operated at each printing operation.

- To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangementsof parts and combinations of devices to be hereinafter described and claimed. A In the accompanying drawings wherein like reference characters represent corresponding parts in the various views, Figure 1 is a central, vertical, front to rear sectional view of oneforrn of typewriting machine embodying my invention. Fig. 2 is an enlarged detail vertical front torear sectional view showing a portion of the indicating mechanism and the associated parts, and Fig. 3 is a front elevation of the same.

I have shown vmy invention applied to a Monarch machine though it should' be understood that it may be applied to other forms of typewriting machines.

The frame of the machine comprises a base 1, corner posts 2 and a top. plate 3. A suitable carriage (not shown) is mounted on the top plate to travel from end to end of the machine and a platen 4, diagrammatically shown, is carried by the carriage. Key levers 5 are fulcrumed on a fulcrum-plate 6 carried by'the base of the machine. Each key lever has the usual key 7 and restoring spring 8, and a sub-lever 9 is pivotedtoeach key lever at l0, the lower end of the sub-lever being slotted at 11 for cooperation with a fixed fulc'rum rod l2 vtype bars being pivoted on a pivot wire 17 seated in a segment'lS, the type bars `Working in guide slots 19 in the segment. The type hars are segmentally arranged to strike upwardly andrearwardly against the 'platen 4. A universal barZO extends beneath the Various key levers and is carried by a universal bar frame 2l piv'otcd at 22 in the basel 'of the machine frame. The frame 21 for the universal bar has a rearwardly directed, centrally located arm 23 projecting therefroml and connected to and extending upwardly from this arm is a link 24 con' nected at its upper ond to a forwardly extendingV arm 25 of a dog rocker 26 that projects from a rock shaft 27 pivoted in a fixed part of the machine. The feed dogs 28 coperate with a'suitable feed rack 29 carried by the i carriage. Another link 30 is connected tefandextends upwardly from the arm 23 and is connected at its upper `end 31 to the rear end of a ribbon vibrator actuating v40 passesfrom one ribbon spool to the other through guide slots 4l in the vibrator' in the usual manner. The ribbon lspools may be turned through the bevel gears 42, 43 and shaft 44 from the carriage drum (not shown) in the usual manner. The features thus far described constitute parts of the Monarch machine and it will be understood that each depression of a key lever causes the ribbon to be elevated or moved laterally,- in the usual manner, by the vibrator into the path of the type as it approaches the platen and the vibrator is lowered to expose the last written character as finger key is rel eased.V

Depending lugs 45 and 45l1 extend from the top plate and are perforated to form bearings for a rock shaft 4G which extends fore and aft of the machine and to one side. of the vibrator lever 32. Two collars 47 and 48 are secured tothe shaft 46 by screws 49 and 50 respectively, one collar being located on each side ofthe lug 45l to prevent a longitudinal movement of the shaft in its bearings. The rear end of the rock shaft has a crank pressure on the arm 51 secured thereto and this arm is adapted to abut in its upward movement against the lower end of a screw 52 that is threaded into an Opening in the top plate, so that the screw constitutes an adjustable stop to limit the upward movement of the crank arm and to limit the turning movement of the shaft in one direction. A coiled spring 53 surrounds the rock shaft and is connected at one end 54 to the lug 45, whereas the opposite end 55 of thespring is secured to the collar 47.

`This spring exerts a pressure te turn the shaft inthe direction of the arrow in Fig. 3 and tends to maintain the crank arm 51 in Contact with its stop 52. The for- Ward/end of the shaft 46 has a printing point `indicator/1 y screw 57,*the stem of which passes through a holev in the.

156 secured thereto by suitable means, such las ya headed g i lower end of the `indicatorand takes into' a' threaded v@ opening inthe end of the shaft.V l The indicator may 4be made of sheet metaland formed ask indicated in Figs.

-Zand 3. `The pointer portion of theffin'dicator is preferably fiat on top, as-indicated at 58, and is 'substan'n tially the width of 1anupper 'case letter. vertical ,y

groove or line 59 is provided on the' lrontifac'e ofthe'inif` dicatorand this represents the exact vertical center of a letter imprinted at the printing point. The upper end of a link 60 is pivoted at 61 to the crankarm 5l,

whereas the lower 'end of this link is detachably piv- .noted at 62 to the arm 23. A leaf spring 63 is secured at one end 64 to the universal bar trame, or the arm 23, which lforms a part thereof, and the opposite end oi the 5 spring is perforated to receive the pivot G2 and thus prevent the accidental detachment of the link from 'the arm 23. The link 60 is preferablya two-part link, the upper member of which is threaded at its lower end,

as at 65, for coperation with an internally threaded Vl0 lower member 66 so that the two members may receive a relativeadjustment to effect a lengthening or shortening of the link.

The indicator stands and moves between the ribbon vibrator and the platen and normally the ribbon is in the lowermost position to expose the writing and the indicator is normally in theposition shown in Fig. 3 where it accurately indicates the printing point or the character at the printing point. When a key lever is depressed the vibrator will be moved to one side, around the rock-shaft 46 as a center, as the ribbon is being moved into the path oi the type which is approaching the platen. When pressure on the finger key is released the universal bar is elevated and the spring 53 forces thevindica'tor and the parts connected thereto to their normal positions and the indicator will be brought to the position shown in Fig. 3 when the crank arm 51 is brought into contact with the stop 52. The adjustment oi the stop 52 nicely determines the normal position of the indicator and the adjustment o the memlfiber oi the link 60 compensates for any adjustment of and'd s not interfere with or modify the operation of the'riribon mechanism or ribbon vibrator and the means iorac't ting it.
