Laim Patent No. 61,253, and January 1 5, 1867.

FRAME POR ARTIFICIAL SLATES.

VTO ALL WHOM IT MAY CONOERN:

Be it known that I, WILLIAM Jones Rimes, of Washington city, District of Columbia, have invented 'a new and 'useful improvement in Frames for 'Slates and attachments; and I do hereby declare that the following is a i'ulland exact description thereof, reference being had to4 the accompanying drawings'andto the let-'ters of reference marked thereon. In

Figure 1 in said drawings, A represents a slate or sheet of argillaceous stone, porcelain, ivory, Wood, Etc., within a wooden4 frame, B, with my slide ruler C thereon, and the lines and figures on the frame for a gauge.

Figure 2 shows the slide ruler C partly removed; and

Figure 3, the same, whollyl removed, exhibiting a recess or depression, D, beneath the same, to serve as a receptacle for slate or lead peucils,v&c., E, 'and whichY may'also be prepared for pencil sharpening. In

Figure 4, the recess or depression D,'to be usedvas a pencil holder and Sharpener, is shown in the edge of a slate frame.

Figure 5`shows the ruler or gauge C removed from the frame. Y p

Figure 9 is an enlarged section across the middle of the frame B, iig. 3, to show the groove in which the ruler or lid C slides, and the recess or hollow D, whichconstitutes the pencil holder and Sharpener).v V

Figure 11 is a longitudinal section of the frame B, showing the depression or receptacle D, the surface of the latter being covered witlra suitablel rough material for pencil sharpening. i

The name slate is universally applied to the article used in schools and elsewhere for frequent writing and erasure, whether such articles are made of argillaceous material, of ivory, of porcelain, oi' metal, of prepared paper, wood, or other substance. The present invention consists incertain improvements in the frames of all such slates, whereby economy and convenience are secured andimportant advantages are obtained, as shall be hereinafter described.

To enable others skilled in the arts to make and use my invention, I will proceed-to describe the same.

In slates of rigid and brittle materials, as stone, porcelain, and ivory, it is impracticable to make hollow frames, by turning the edges thereof, and hence wooden or other frames are madeto surround said slates, and I form receptacles in such frames by mortilsing, sawing,bcring, or cutting grooves in them, or otherwise making hollows or recesses (D, igs. 2, 3, 4) in which t deposit a pencil, pen, rubber, knife, le, tc. In the bottom or sides of said grooves o1' hollows, or of one of them in each frame, which may be in the side of the frame, (figs. '2 a\nd'3,) or the edge thereof, (5g. 4,) I arrange a pencil Sharpener, iig. 11, D, either by inserting and attaching thereto a piece of sand paper, glass paper, emery paper, or cloth, or coating the material of the frame' with glue orits equivalent for the purpose, and then covering the same with sand, emery, powdered glass or stone, or. other suitable material; or a solid metal, asa le or other Sharpener, may be inserted and i'ixed therein. The hollow D, formed asv described, and to be used as a' receptacle for pencils, tc., is then to be protected by a-suitable covering, (C, figs. 1, 2, 5,) which should preferably slide over this concavity, and be made ilush with the surface of the frame. This slide, C, should be made of hard Wood, metal, gutta percha, or other hard substance, or be sfo fortified as to retain a good edge and perfect straightness, in order that it may serve the purpose of` a ruler inl drawing straight lines. The edges of the slide O should have such a shape as to correspond with or it into the sides of the groove in the frame, so as to allow it to be moved in said groove when pressed with the fingers,

and yet to retain its place, either by friction or by a spring or other mechanical contrivance. This slide C may also have engraved or otherwise marked upon it, on one or bothsides, cross lines and igures or other characters indicating measures of length. On one or more sides or parts ofthe frame B, I also propose to indicate measures of length by marks, indentations, figures, tc., such marks being used in connection with the ruler C in drawingstraight lines across the slate. These marks will also be of -use in training the eye of a child to make straiglrt lines, even without applyingethe ruler, and will enable it to acquire a quick and ready perception rof' measures of length. What is usually denominated a black-board is in every respect a slate constructed'on an extended scale, whether made of wood, slate, metal, or any of the materials used for the purpose;

and it is manifest that a black-board Ato which-the devices herein apply, fallsfstrictly Within the scope of my invention and claim. It will thus be seen that, by my invention or improvement, great advantages are secured to all who use the ordinary slate, by' the provision I`have made for combining with said slate a pencil depository,

a ruler,

a gauge, a pencil-Sharpener, and a slate-cleaner, Without increasing the size or weight of the slate or adding materially to its cost.' The machinery or implements lnecessary to apply my improvements are of a simple character, most ci: them, if not all, now being in use in mechanical establishments. Olaz'm.

Having thus described my invention, what I claim, is

1.F The combination .of a hollow in' a slate frame, to be used as a .receptacle for pencils, sharpeners, and other utensils, with a suitable covering constituting a ruler'and gauge, substantially as described.-

2. Marking upon said ruler so arranged measures of length, substantially as shown and described.

3. Marking upon the frame of a slatemeasures of length, substantially as described.

In testimony whereof, I hereunto subscribe my name,'this twenty-second day of October, A. D. 1866.
