TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 299,785, dated June 3, 1884.

Application filed'llday $23, 1883. (No model.)

To all whom it may concern:

Be it known that we, GEORGE H. HER- RINGTON and DAVID G. MILLISON, both of Wichita, in the county of Sedgwick'. and State of Kansas, have invented a new and Improved Type-Writer, of which the following is a full, clear, and exact description.

The object of our invention is .to furnish a simple and inexpensive typewriter, capable of being used for printing words and sentences for the amusement and instruction of children,

' and so simply constructed and easily operated that any child can readily use it for the purpose of acquiring a knowledge of spelling,

.face to be printed ufijn.

composing, and punctuating correctly.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part 'of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a vertical transverse section of ourimproved type-writer. Fig. 2 is a front view of the same.

A is a hollow post, made of sheet metal or other suitable material, and affixed to a baseplate, B, that is turned up or grooved at one side to fit a groove in a guide or ruler, O, which serves to steady the machine, and at the same time serves as a guide for the sur- The base-plate B slides freely upon the guide or ruler O, and can be detached from either end thereof.

D is the type-wheel, attached to a spindle or axis, a, which passes through vertical slots in the post A.

b is a tube or box fitted to slide upon the post A, and carrying the axis a of the typewheel, so as to' hold the same securely and steadily, while allowing it to be moved up and down upon the post.

. cis a knurl upon the axis a, for use in turning the type-wheel D.

dis a spiral spring within the post A, and

attached to the axis a, so that it tends to press the axis and the type-wheel upward for retaining the type in contact with an inking pad or roller, 6, which is fixed upon the top of the post A. The letters or characters upon the type-wheel are to be made of vulcanized rubber or any other suitable composition, and secured to a non-elastic band or rim, f, that is made to fit closely upon the periphery of the type-wheel. This construction allows the letters or characters to be readily changed, so that any style or size may be used. The typewheel is formed with an inner flange, out. with V-shaped notches that form projections g, each notch being opposite a letter upon the wheel,

so that when ,the wheel is pressed down the notch of any particular letter will pass upon the knife or guide I that is fitted upon the base-plate B, by which means the type-wheel is held correctly in place, and a proper alignment of the printing is secured. In place of these V-shaped notches, there may be perforations in the flange to pass over a pinfastened upon the base. The type-wheel is also provided with an outer flange, i, that is marked with the letters and characters corresponding to those upon the face of the type-wheel, so that they serve as a guide in the printing operation. The base-plate B has an opening, k, 5 beneath the typewheel, at which the printing is done by the type being pressed through the opening; and the base is also formed with a 1 front flange, Z, that projects over above the flange z of the type-wheel, so as to serve as a guide for showing when any letter is in the correct position for being printed from.

This device is simple and inexpensive, and can be readily used for the purpose of printing words and letters. 8 5

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of the vertically-slotted hollow post A, the grooved fixed ruler O, the go slide-base B, detachable from either end of said ruler, the type wheel D on axis a, the upwardly spring-pressed slide-box b, carrying said axis, and the inking-pad e, journaled on a shaft fixed on top of the post, whereby there 5 is formed a type-writer, adapted to be used as described.

2. In a type-writer, the combination, with the standard A, having the slotted base B, and the inking-roller e, secured to the upper end of said standard, of the type-wheel D, constructed substantially as herein shown and described, and journaled in yielding bearings on said standard, as and for the purpose set forth.

3. In a type-writer, the combination, with 5 the hollow slotted standard A, the base 13,

and the inking-roller e, secured to the upper end of said standard, of the type-wheel D, axis a, sliding boxes b, and spring 61, arranged within the post and secured to said axis and base,

10 substantially as herein shown and described.

4. In a type-writer, the combination, with the hollow standard A and the vertically-
