IMPROVEMENT IN SLATE-FRAM ES.

Speccation forming part of Letters Patent No. 99,841, dated February 15, 1870: reissue No. 6,221, dated January 12, 1875; application led December 1U, 1874.

To all whom yit 'may concer-n Be it known that I, SAMUEL B. Busn- FIELD, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Slate- Frames; and I do hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which Aform a part of this specification.

The nature of my invention consists in a slate-frame provided with an orifice for the insertion of a pencil; also,`in a'sliding bar in combination with and at right angles to the recess or orifice in the slate-frame. It also consists in the combination with a slate-frame of a corrugated pencil-sharpening bar, all as hereinafter more fully set forth.

ln order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation,referring tothe annexed drawing, in which- Figure is a front view of a slate embodying my invention, the slate-frame being partially in section. Fig. 2 is a transverse vertical section of the frame and slide which covers the pencil-case.

A represents the slate, with the frame B made in anyrof the known and usual ways. One side of the frame Bis bored out, as shown in Fig. 1, so as to form a convenient receptacle a, in which the pencil may be kept. The upper end of this receptacle may be covered by a sliding bar,- b, which is dovetailed into the frame at right angles to the receptacle or orifice a. The upper side of the sliding bar b is corrugated or otherwise made uneven, so that it can be used to sharpen the pencil upon.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1. In a slate-frame, a sliding bar in combination with and arranged at right angles to the recess a, substantially as set forth.

2. The corrugated pencil-sharpeniug slidebar b, in combination with a slate-frame, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of November, 1874.
