SPECIFICATION forming part of Letters Patent No. 270,470, dated January 9, 183.

Application tiled October 25. 1882.

To all whom 'it may concern Be it 'known that I, GEoRGE W. PEoAN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in School Slates7 of which the following is a specitcation.

My invention consists in the combination, with a slate having one end or side of its trame rabbeted on its face, of a straight-edge the ends of which are titted in guides in opposite sides of the frame, and which is capable of being moved along the slate to enable parallel lines to be drawn, and of being moved into the rabbet when it is desired to expose the Whole surface of the slate for writing.

The invention also consists in forming a pencil receptacle or cavity in the aforesaid rabbet, whereby the straight-edge, when slid into the rabbet, is made to serve as avcover for the said receptacle or cavity.

In the accompanyingdrawings, Figurel represents a plan ot a slate embodying my invention. Fig. 2 represents a section lengthwise ot' the slate, and Figrepresentsa transverse section thereof. y

Similar letters of reference designate corresponding parts in the several figures.

A designates the slate. B B designate the top and bottom enti pieces of theframe, and C designates the side pieces thereof'. The pieces forming the traute may be secured together by tenons and mortises, or in any other suitable Way` and in them is formed the usual groove, a, herein the slate A is held.

The piece B, forming the upper end of the fratrie, is rabbeted at bon one face, and in the frame is formed a second groove, c, the inner wall ot' which is iiush with the bottom of the rabbet b, as best shown in Fig. 2.

In the bottom of the rabbet bis formed a cavity or recess, d, which forms a receptacle for pencils.

D designates a straight-edge, which is of a width and thickness to'll the rabbet b iiush (No model.)

with the face of the frame. The ends of the straightedge are provided with tongues e, titting in the grooves o in the sides U, and the upper edge is also provided with a tongue, e', adapted to t in the groove o in the upper end piece, B, as shown in Fig. 2. The straightedge D is capable of being slid up and down in the grooved sides C, and provides for drawing parallel lines. When the straight-edge is slid upwardinto the rabbet bit is out of tne Way, and leaves the Whole surface ot' the slate A exposed for writing. It also serves as a cover for the receptacle or cavity d, andprevents the pencils from being lost. The face ot' the adjustable straight-edge is flush with the frame, and the slate can be laid down tlat either face up. The straight-edge cannot be lost or lorgotten by the scholar, and is a Very desirable addition to school-slates for childrens use.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a slate having one end or side of its frame rabbeted on its face, of a straight-edge the ends Ot' which are litted in guides in opposite sides ot' the frame, and which is capable of being moved along the slate .and into the rabbet when desired to expose the whole surface ot the slate for writing, subtantially as herein described.

2. The combination, with a slate having one piece of its frame rabbeted ou its face and provided with a receptacle or cavity, of a straight-edge the ends ot' which are fitted in guides in opposite sides ot' the frame. and which is capable of being moved along the slate and into the rabbet, so as to serve as a cover to said receptacle orcavity, substantially as herein described.

GEORGE W. PEGAN.
