Description
UNITED STATES PATENT OEEIcEo JESSE LABAE, OF SLATINGTON, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND ROBERT MGDOWELL, OF SAME PLAGE.
IMPROVEMENT IN SCHOOL-SLATES.
To all whom it may concern:
Be it known that I, JESSE LABAR, of Slatington, Lehigh county, Pennsylvania, have in vented an Improvement in School-Slates; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention consists of certain grooves and holes made in the corners of a slate-frame, in the manner described hereinafter, forthe reception of wire fastenings, by which the corners of the frame are effectually secured without presenting any unsightly or inconvenient projection.
On reference to the accompanying drawings, which form a part ot' this specification, Figure l is a front View, partly in section,of my improved school-slate; and Fig. 2, an edge view of the same.
The frame is made, as usual, of two side strips, A and A', and two end strips, B and B', of wood, the whole of the strips being grooved on the inside, as usual, for the reception of the edges of the slate D. The frame is secured at each cornerbymortise and tenon and a peg, a, as usual. After the frame has been thus secured the corners are neatly rounded off, and then, by the aid of suitable mechanism, a
groove, b, is cut in the edge ateach corner of the frame, the groove terminating abruptly at the points y, where it communicates with a hole, m, bored into one of the end strips of the frame,
4and at the point y', where it communicates with a hole, m', bored into one of the side strips 'of the frame.
The metal fastening is composed of a piece of Wire, n, bent to conform to and lit in the groove cut in the corner of the slate-frame, the ends ofthe wire being bent abruptly, so as to fLt into the holes m and m. When driven tightly into its place thewire forms a most secure fastening at the same time it is embedded in the frame, and therefore presents no inconvenient or unsightly projection.
I claim as my invention and desire to secure by Letters Patent- The groove .fr and holes m and m', communieating with the said groove, the whole being made :in the corner of a slate-frame for the reception of the wire fastening u, as and for the purpose herein set forth.
In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
JESSE LABAR.
