BERNHARD B. HARTLEB, OF BALTIMORE, MARYLAND.
COMBINED SLATE AND SCHOLARS COMPANION.
SPECIFICATION forming part of Letters Patent No. 546,848, dated September 24, 1895.
Application filed March 29, 1895. Serial No. 543,712. (No model.)
To all whom it may concern:
Be it known that I, BERNHARD BENJAMIN HARTLEB, of the city of Baltimore, in the State of Maryland, have invented certain Improvements in a Combined Slate and Scholars Companion, of which the following is a specifioation.
In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which-- Figure 1 is a perspective View of the invention. Fig. 2 is a side view, a portion of the same with a certain plate which constitutes an element thereof removed. Fig. 3 represents a side and a cross-sectional view of the plate removed from Fig. 2.
Referring now to the drawings, A is the body of the slate, and B the frame.
0 is the scholars companion, consisting of a box with a hinged lid a, provided, as is usual, with certain divisions, whereby compartments are formed for pencils and small articles. To admit of the attachment of the box 0 to the slate, the frame B of the slate is pro vided at its lateral edges with grooves b, and the box with a metallic plate 1) at each end, the said plates having pins 0, which enter the grooves b. For the sake of simplicity and cheapness the pin is made by sawing two outs in the plate and turning in the portion between the cuts, as shown in Fig. 3. When the plates D are secured to the ends of the box 0, with the pins 0 in the grooves b, the box may be slid longitudinally of the slate, and upon its reaching either end thereof turned over, as seen by its dotted delineation in Fig. 2, so as to pass to the other side of the slate.
WVhen the box is turned to the under side of the slate and retained at the end, as shown by its dotted delineation in Fig. 1, it serves to hold the slate in an inclined position, which is better for writing than a horizontal one.
To adapt the box as a ruler, its longitudinal edges are provided with strips 01, and these are preferably formed integral with the boxbottom, which extends beyond the sides.
In order that parallel lines may be drawn with a pencil on the slate, the side frames thereof have teeth (2, formed by notching the frames, as shown. On one side of the slate the teeth are shown as at equal distances apart, while at the other the teeth are in pairs.
The bottom of the box is cut away or recessed its entire length, so as to produce teeth f, which may be pressed against the teeth e, so as to hold the box at a right angle with the sides of the frame while lines are being drawn with a slate-pencil. Sufficient loose motion is provided between the box and slate to allow of the teeth f being lifted clear of the ones 6 when the box is to be moved along the slate. Instead of notching the slate-frame, it could have toothed strips of metal placed in grooves 9, (shown in dotted lines in Fig. 1;) but this construction would be expensive and not more effective than the one before described.
I claim as my invention In combination with a slate, a box pivoted to the slate frame, adapted to be swung around the ends of the frame to either side of the slate, substantially as specified.
BERNHARD B. HARTLEB.
