TYPE WHEEL INKING MECHANISM FOR TOY TYPEWRITERS Filed Jan. 24, 1947 INVENTOR Samzze [fie/ 17w ATTORNEYS? 7 h Patented Jan. 2, 1?51 TYPE WHEEL INKING MECHANISM FOR TOY TYPEWRITERS Samuel I. Berger, Newark, N. J. 7 Application January 24, 1947, Serial No. 724,042

1 The present invention is concerned with the toy typewriter made the subject of my. prior application Serial No.'658,318 filed March--29, 1946, which has issued as Patent No. 2,486,102, dated ovember 1, 1949, and has for its objects to sim- {plify the construction and to enhance the visi- -'bility of the typing area of the platen. I In the accompanying drawings in which is shown one of various possible embodiments of the several features of the invention,

Fig. 1 is a perspective view of the toytypewriter of'the present invention'showing' its general appearance with the simulated keyboard and associated structure in place, 1

Fig. 2 is a fragmentary view intransverse cross section, taken on line 2-2 of Fig. 1, and Fig. 3 is a perspective view showing the type wheel and associated bail and inking'roller con- ;struction. -11

'Since the construction in its gen j ral outline follows closely that of the'application above identified, only so much of the construction has been shown as is needed to a comprehension of the present improvement and the general description will be correspondingly brief. 'noted that the casing structure simulates the {general appearance of a modern portable typewriter including, as it does, the base l, a simulated standard keyboard l2, a housing l3 to the rear thereof, of the shape and dimensions commonly used on standard typewriters to enclose the key lever basket and the ribbon mechanism, and a platen structure l4 to the rear., The housing portion is enlarged at its middle as a hood 15 to enclose the main operatingjtjparts of the toy typewriter. The sham keyboard is divided at 20 and a single key lever 2| protrudes therefrom, depression of which efiects the typing operation. There is also a spacer lever 22 protrud fing through the-forward part of the housing to operate the spacing escapement (not shown) and not material to the presentiniprovement. The type wheel 23 is mounted on an axle 24 bearing in the side walls of the carriage 28, upon one end of which axle is afiixed the indexing wheel 25 whichbears on its peripher he same sequence of characters as those of the periphery of the type wheel 3; and serving, in association with the index finger 26 protruding from the hood IE, to set thetype wheel for typing a selected character. The. actual typing is effected by depression of the key lever 2| which, through link 2'! rocks the type; heel mounting carriage 28 about its pivot 29 to; 'g the selected type into imprinting engagement with the In general it is 3 Claims. (01. 197-47) paper St on the platen. Spring means (not shown) returns the parts to normal position upon .release of the key lever 2|. 1

For inking the type wheel at the characters to be imprinted, an absorbent ink roller 3| is interposed between the type wheel and the platen. That ink roller is mounted on a bail 32, which straddles the type wheel diametrically thereof, with the cross bar 33 thereof at the front of the type'wheel-or that side thereof remote from the roller 3| and the other leg 31 desirably hasa median outturned kink 46 which servesas the pointer to indicate the position of imprint on the paper.

The sheet metal bail 32 is of such width that the distance between its arms is greater than the thickness of the type wheel for adequate clearance and has a pair of tongues 43 cut out from near its ends and from one edge thereof and bent inward, as shown, to extend in close contiguity to the respective edges of the type wheel rim. Thereby lateral-displacement of the bail and type wheel relative to each other is precluded and the ink roller always remains in registry with the type to be inked. It will be understood that the inturned tongues 43 could be used adjacent the cross bar f the bail where the latter,

.as in the copending application above identified,

is at the ink roller side of the mechanism.

Preferably the ink roller is normally kept' out of contact with the type wheel by a stop post 4| of sheet metalrisingfrom' the frame and e"n'- gaging the sleeve 39. In the typin operationa's the carriage 28 is rocked forward, the sleeve 39 disengages stop 4| and the spring holder 34 then brings ink roller 3| into engagement with the type wheel. 1

Preferably the upper end of the hood l5 has a circular cut-out 42, and in combination with the arrangement of the inking roller bail unobstructed at its inking end by the bail cross bar, affords considerably enhanced visibility of the typed region as contrasted with the construction of my prior application above identified.

As many changes could be made in the above construction and many apparently widely dif- 1. In a toy typewriter of the character described, a body, a platen at the rear thereof, a type wheel having a horizontal axle, a hood encompassing said type wheel, the axle for said type wheel protruding through said hood, a dialing knob on said axle, an inking roller carrying bail pivotally mounted on said axle and within said hood, the free ends of the bail legs terminat ing at the platen Side of said type wheel, and an inking roller rotatably mounted between said bail legs and adapted to .ink the characters about to-beimprinted against the platen.

2. In a toy typewriter of the character described, a type wheel having a horizontal axle, a platen, an ink roller interposed between said type wheel and said platen, a carrying bail for said ink roller, said bail straddling said type wheel diametrically thereof, being pivoted on said axle and having its cross bar at the side of said type wheel remote from said platen, said ink roller being mounted between the legs of said bailnear the free ends of the latter, and a pointer betweenisaid bail legs.

3. In a toy typewriter of the character described, a type wheel having a horizontal axis,

' a platen, an ink roller interposed between said type wheel and said platen, a carrying bail for said .ink roller, said bail straddlin said type wheel diametrically thereof, being pivoted on said axle, and having its cross bar at the side of said type wheel remote from said platen, a

wire spring holder for said ink roller, extending across the free ends of the legsof said bail and a pointer on said holder between said bail legs resiliently afiixed therebetween, and a pointer on said holder between said bail legs.

.4. In a toy typewriter of the character described, a type wheel having a horizontal axis,

-a platen, an ink roller interposed between said type wheel and said platen, a carrying bail for said ink roller, said bail straddling said type wheel diametrically thereof, being pivoted on said spring holder, said spring holder having a second and outer leg with a median kink serving as a pointer.

- ment with the type on the type wheel.

5. As an article of manufacture, a wire spring holder for the inking roller of a toy typewriter of the character described, said holder comprising a coil spring loop having two generally parallel legs extending therefrom and unitary therewith, one of said legs serving for the mounting of an ink roller, the other of said legs having an outward kink in the middle of its length to serve as a pointer.

6. In a toy typewriter of the character described, a. casing havin a simulated keyboard, a hood rising therefrom, a type wheel encompassed by said hood and having an axle protruding therefrom, an indexing wheel exposed laterally of said hood and affixed on said axle, an inking bail pivoted on said axle and within said hood, the free ends of the bail legs being exposed at the platen side of said hood, and an inking roller accommodated between said free ends, the hood having a circular cut-out, said cut-cut and said bail arrangment contributing to enhanced visibility of the type.

7. In a toy typewriter of the character described, a type wheel having a horizontal axle, a platen, an ink roller interposed between-said type wheel and said platen, and a carrying bail for said ink roller, said bail straddling said type wheel, being pivoted on said .axle and .having side arms spaced by a distance materially greater than the thickness of said type wheel, said arms having rout-out .inturned tongues near said ink roller and extending adjacent the respective rim edges of the type wheel, thereby to assure maintenance of the ink roller in align- 8. In a toy typewriter of the character described, a type wheel having a horizontal axle,

.a platen, an ink roller interposed between said .having tongues cut inward from the edges of the arms thereof and turned inward generally parallel thereto to extend in close contiguity'to the respective rim edges of the type wheel and thereby maintain the ink roller substantially in register with the type on the type wheel.
