VILLIAM F. BAADE, OF BUFFALO, NEW YORK.

IMPROVEMENT IN ALPHABET-CASES.

Specification forming part of Letters Patent No. 146,565, dated January 20, 1874; application filed December 22,1873.

To all whom it may concern:

Be it known that I, WILLIAM F. BAADE, ot` the city of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Alphabet- Cases, ot which the i'ollowingis a specification:

This invention relates to object-teaching devices; 'and it consists in the combination of two or more adjustable or movable alphabets,V

and one or more pictures on a movable belt or apron, so arranged that different objects or pictures may be presented, the alphabet being so constructed and arranged upon movable surt'aces that words, figures, or sentences can be built up or presented in such a manner that the pictures or other objects connected therewith, as well as other matter, can be explained thereby without the necessity of removing the letters or pictures from the case.

In the accompanying drawings, in which like letters represent like parts in the several iigures, Figure 1 is a front eleva-tion of my said invention; Fig. 2, a back view of the same, showing a slate connected therewith. Fig. 3 represents a vertical longitudinal section through the center of the case.

A is the case; B, the top or front; C, a series ofgrooves or channels cut through and arranged lengthwise of the same. l) is an open space near the top of the case, through which the letters and figures are seen. Eis an open space, through which the pictures are exposed. F is a channel in the face B, through which projects a thumb-piece, G, from the picture bolt or apron, and by which it is moved.

The letters H represent the thumb-pieces for moving the alphabet aprons or belts, and the letters I represent the said aprons or belts. They are all arranged to move upon a stationary fixed support, J., which is rounded at both ends, as shown in the drawing, andforms a table or support for the said belts at the top, for the alphabet, and also the picture-belts.

There are as many belts or aprons as there are-alphabets or sets of pictures. The alphabet-belts are all arranged so as to be easily moved back and forth by means ot' the thumbpieces H, while the picture-belt is so constructed and arranged that it canbe moved by the thumb-piece G in a direction continuously for= ward or back, as maybe desired; andif required, the alphabet-belts may be moved in a similar manner. I have shown the picturebelts arranged lengthwise of the case, but it can be placed crosswise, which might, in some cases, be preferred. K, in Fig. 2, represents the slate as set in the back of the case. Fig. l, a top or face view of the belts are shown by dotted parallel lines, marked I, the narrow parallel lines representing the alphabet-belts, and the wide one the picture-apron.

All ot' the belts I have one or more alphabets and ii gures printed or otherwise marked thereon; and it can be readily seen from this description and drawings hour any word or sentence may be presented by bringing the proper letters to view, in the manner and by the means hereinbefore mentioned.

I claim as my invention- 'lhe combination of the case A, having the openings or channels C C, with the series of movable and adjustable alphabet-belts I, substanti-ally as and for the purposes described.

WILLIAM F. BAADE.
