IMPROVEMENT IN'IBLACKBOARDS.

Specification forming part of Letters Patent No. 173,516, dated February 15, 1876 application filed To all whom it may concern y Be'it known that \ILDE Wrrtr O.TA1'L0R, of Brooklyn-,in the county of Kings and State of New York,have invented' a newand Improved Sectional Blackboard, of .which the fola sectional blackboard which can be readily placed against a wall andreadily dismembered and divided into a seriesof boards, which can be separately exhibited'in di'lferent parts of the same room. A a

My invention consists, principally, in constructing'the board of a series of horizontal sections, and combining each section with separate supporting devices that are fastened in the wall, allas hereinafter more fully described. In the accompanying drawing,-theletters A A represent several sections of my improved blackboard. Each sectionmeasures the full length horizontally of the board, but only part of the height *thereof, so that the complete board is only' -n-oduced by super-posing a se- The lower edgeofeachsection is beveled, and for its support a series of sloping brackets, B B, are secured 'infthe wall, as shown. NVllen a section, A, is placed upon any two or more such brackets B B it is properly held in place on the wall. v t

I propose to. secure such brackets in differ- January .17, 187 6.

cut parts of the same school-room, so that the teacher may display the sections'of the same board at difl'erent places, or unite them into a smaller or larger board, as occasion may require. t

In order to produce a perfect match at the contiguous edges of two sections, AA, I have also beveled thenpper edges of the sections, as shown, so that their cross-section will ap- The nppermost s ection, however, can be flat at the upper edge. V V The face of each section may either be plain, to be written or drawn upon, or it may be provided with projecting ribs a, or other support- 7 ing devices for letter-blocks.

It will be seen that by my improved arrange ment each section of the board will be separately supportedon the wall, and yet all the sections together constitute a perfect blackboard or bulletin.

I claim as my in'vcntion- 1. A blackboard composed of a series of horizontal sections, A A, placed vertically one above the other, and combined with a series of tiers of brackets, B B, in such manner that the several sections of the same board are separately supported by separate brackets, substantially as set forth,

2. The section A of a blackboard, beveled at the lower and also at the upper edge,'substantially as specified, for the purpose set forth;
