IMPROVEMENT IN TYPE-WRITERS.

Specication forming part of Letters Patent No. 175,661, dated April 4, 1876; application filed November 29, 1875.

To all whom it may concern Be it known that I, EDWARD A. CALAHAN, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Type-Writers', of which the following is a specification rloys with which a child can do something are always more acceptable, as wel] as amusing, than those that are simply played with. The object of this invention is to furnish a toy that resembles a printing-telegraph, but

which 1s cheap and can actually be used in printing. This toy is also available in spelling exercises and accurately records the letters selected, and impresses by the eye, as Well as the memory, the peculiar spelling on the mind.

In the drawings, Figure 1 is an elevation of the instrument or toy, showing the dial, typewheel, and other appliances; and Fig. 2 is an elevation of the toy endwise of the printinglever.

The frame a is adapted to sustain the parts of the apparatus 'or toy, and also the dial or dial-ring b, or to be formedr partially by such dial-ring. The shaft c for the type-wheel is at the center of the dial or dial-ring, and secured upon this shaft c is the type-wheel c, and rag-wheelf, against which a spring, g, presses, having a double inclined end, so that the type-,wheel and rag-wheel can be turned either way by the crank or handle h, or otherwise.

The rag-wheel and its spring serve to bring the particular letter upon the type-wheel accurately to position, and hold the samewhile being printed, there being the same number ot' notches in the rag-Wheel that there are divisions in the type-Wheel and dial.

The inking-roller k is hung by links lso that it rests in contact with the type-wheel. The arm m carries a reel, n, upon which a strip ot' paper is Wound. Upon the pivot 3 the printing-lever o swings. It 'has a fingerrest, 4, at one end, a paper guide or roller, 6, at the other end, andan impression-pad, r, in the proper position to press against the type that is in position for printing.

The feed-roller s is also upon this shaft 3, and there is a pawl, t, upon the printing-lever catching againstthe paper as it passes over the roller s, and serving to move the paper along as the lever is moved to give the iinpression.

The pawl S prevents the paper moving backwardly as the printing-lever is returned to a normal position by the spring c. n so doing the roller or guide 6 draws the p( per oft' the reel sufficiently tor the next impression, and it will be apparent that the paper is loosened as the printing-lever is moved and the feed operates in consequence of the roller 6 rising. This prevents the paper being unwound too much by a sudden movement of the printing-lever.

lt will now be apparent that the toy or instrument aforesaid can be used by a child, the type-wheel being turned around to successive letters denoted by the pointer, and the lever being depressed intermediately to print the letter, upon the strip oi' paper and to cause the paper to move forward. Numbers might be added to the type-Wheel, it' desired.

I claim as my inventionl. rlhe printing-lever o, linger-rest 4, and impression-pad 1', in combination With the type-Wheel e, shai't c, crank-handle h, ragwheel f, and spring g, substantially as set forth.

2. The printing-lever o, ngerrest 4, impression-pad r, in combination with the feedroller s, paw] t, and guide 6, substantially as speciiicd.'

3. The combination, in a hand printing instrument, ot' a lever, o, linger-rest 4, roller s, guide 6, type-Wheel e, handle h, dial and pointer, substantially as set forth.

Signed by me this 24th day ot' November, A. D. 1875.
