CASE FOR MATHEMATICAL INSTRUMENTS.
SPECIFICATION forming part of Letters Patent No. 758,700, dated May 3, 1904,
Application'filed September 4, 1903. Serial No. 171,956 (No model.)
To all whom it may concern.-
Be it known that I, GEoRe SCHOENNER, manufacturer, a subject of the Emperor of Germany, residing in Nuremberg, in the Empire of Germany, (whose full postal address is 43 I rauenthorgraben, Nuremberg aforesaid,) have in vented certain new and useful Improvements in Cases for Mathematical Instruments and the Like, of which the following is a specilication.
The usual mathematical-instrument case, which consists of an under part for receiving the separate instruments (compass, tracingpencils, and the like) and a cover adapted to fold thereon, is usually of such a width and length that if a large number of such instruments are to be placed therein it is not possi ble to carry such mathematical instruments in garment-pockets of the usual size.
Now by the present invention a suitable case for receiving a numerous set of mathematical instruments is obtained of a very convenient shape and form, the case being comfor instance, as velvet-and which holds the mathematical instruments arranged in the outer parts of the case apart.
The outer cover (Z, which is made of leather or analogous substance, and the inner cover (2 hold together all the three parts on one edge of the case. Consequently all three parts are held together, as on a hinge, on one longitudinal side of the case, both by the outer casing (Z and also by the inner velvet covering a.
A displaceable pin f is provided which engages in an eyelet 9, formed on the middle piece, and forms the so-called pin-fastening in the case.
In consequence of the arrangement hereinbefore described this improved case in spite of its handy shape and its comparatively small dimensions is adapted for receiving a very large number of separate mathematical instruments.
I declare that what I claim is A case for mathematical instruments consisting of a middle frame having some yielding fabric, stretched over it and of two outer parts covered on the inside with fabric of the same kind and joined in a hinge-like manner with the middle frame which outer parts contain recesses for receiving the mathematical instruments.
In witness whereof I have hereunto set my hand in presence of two witnesses.
GEORG SGHOENNER.
