issued as Patent No. 2,486,702, dated November 1, 1949, and Serial No. 724,043, filed January 24,

194'? and since issued as Patent No. 2,458,137,

dated January 4, 1949, and my previous issued Patent No. 2,398,765, dated April 23, 1945, including the use substantially solely of sheet metal l'and rod stock to genuine portable simulatethe appearance of a typewriter by a greatly simplied construction.

In the accompanying drawings in which is shown one of various possible embodiments of the several features of the invention,

, Fig. 1 is a plan view of a toy typewriter according tothe present invention, showing its general appearance with the simulated keyboard arid associated structure in place thereon,

Fig. 2 is a transverse sectional view thereof taken along line 2-2 of Fig. l,

Fig. 3 is a View similar to Fig. 2, with the key lever depressed, showing the type wheel in typing position, and

Fig. 4 is a sectional detail view of the platen structure on a larger scale taken along line 4--4 of Fig. 1.

Since the construction in its general outline follows closely that of the applications and patent above identified, only so much of the construction has been shown as is needed to afford a clear understanding of the present improvements, and the general description will be correspondingly brief.

Referring now to the drawings, as shown in Fig. 1, the toy typewriter simulates the appearance of a modern portable typewriter presenting as it does a base having a simulated standard'keyboard I2 thereon. This keyboard may be directly printed on the platform I5 or printed on a rectangular sheet metal'plate which is affixed to the surface of the platform. A standard at the center of the base supports theoperating mechanism of the device and a platen structure `I4 is mounted on the base to the rear of the standard. l y

Base `|I comprises a rectangular platform I5 having a downwardly turned skirt I6 on the periphery thereof. Aiilxed'to the rear of the platform I5 at each corner thereof and depending therefrom is a supporting leg comprising a U-shaped strip of sheet metal, presenting a cross piecev l1 and'upstanding sidewalls I1. The up- Pr 'edges 0I sidewalls I1" are beveled as at I8l 9 Claims. (Cl. 197-47) and are connected by tines (not shown) with theV platform I5 to support the latter obliquely, as shown. 1

A key lever 25 is pivoted on an axle 26, the latterv being journalled in side walls 20 rising from the lateral edges of a rectangular bracket i3 affixed to the platform by means of down-v wardly Vturned tines 23 integral with each c orner of the` bracket and which pass through the platform. Each of, thearms 21 ofthe key lever 25 is pivoted to a link 28, the upper end of said link being pivoted by means of an axle 29 tothe obliquely extending arms 30 of a substantially U-shaped sheet metal carriage 3|. The end of each of vsaid oblique arms 30 is pivoted as at 32 to upstanding ears 2| rising from the rear end of each side of the bracket I3. Y

Depending from carriage 3| is a U-shaped bracket 33, the arms of the bracket being aixed to the carriage as at 34. A type wheel 35 having on its periphery the type heads comprising the sequence of letters and numerals, is affixed on Va substantially upright axle 36 journalled in bearingopenings 31 and 38 in bracket 33 and carriage 3|, respectively, and protruding therefrom, the axle inposition of rest being at substantially right angles. to` platform I5.

The typewheel 3 5 is adjustable to a selectedV setting by means of a rotatable c up shaped dial 39 Whichbears the sequence of letters and nu-z merals on its upper Surface. Dial 35 has a hub.

48 unitary therewith on its undersurface and it;

is affixed tothe upper end of axle 35 protruding from carriage 3| by means of a set screw 4| ini; y

said hub, a notch 42 on the -periphery of said dial affording convenient access to said set screw. Dial 39 preferably has a knob 45 unitary therewith on the surface thereof, the peripheries of said dial and said knob being serrated as at .46.'

to facilitate gripping thereof. AV coil spring 43. surrounding said axle 38 between the type wheel and the carriage serves to take up any looseness i 35 by a set screw 49 is preferably provided tostep the type wheel around in effective setting thereof by the turning of dial knob 45. As this 'Y mechanism has been fully described in my aboveV identified applications and patent, it will not be f more fully described herein. A pointer 41 which is lstruck out frOmTcarriage 3| is positioned so as to be near the periphery of said dial 39v to indicate the selected setting thereof.

For applying ink to the type head, an ink retaining absorbent roller 5|) which is itself conventional is preferably provided. This roller ls mounted on a bail 5| integral with and extending outward from the midsection of the cross arms of a substantially U-shaped bracket 52, the arms 53 and 54 of which are pivoted to carriage 3|, preferably by means of hollow rivets, as at .55.

Arm 54 is extended as at 56 and'is connected by pitman 51 to side wall 20 of bracket I3 forY the purpose hereinafter described.

The escapement structure is quite similar-stof.

that of my above identied issued patent and need therefore be but briefly described. escapement box 58 is conventional and sits.. in.. terior parts are not shown. Its protruding pawls 59 coact with an indented rack 60 on theebase" of the platen structure. The escapement is op- The erated.. from .a.-cam .platei 6I. freely.- rotatable..

about the .axle 26. of the keylever, 25-and .connected by a wire link 62 hooked as at 631 to. plate 612'*I at-one end and.toi the mechanism in thelescapement box 58 at the'oth'er'. A' link.'64 pivoted at one end Vto axle.` 29- and Shaving Jazstu'd 65- at its other end' riding infan arcuate slot.
