SPECIFICATION forming part of Letters Patent No. 562,486, dated l' une 23, 1896.

Applicationled November 5, 1895. Serial No. 568,013. (No model.)

To @ZZ lah/0711. it may concern.-

Be it known that I, LITA, (Baroness Putlitz,) of Retzin, Priegnitz, in the German E1npire, have invented new and useful Improvements in a Combined Pen or Pencil Box and T-Square, of which the following is a specification.

This invention relates `to a school pen or pencil box with an accessory, whereby it may at the same time be used as a T-square, so that school-child ren, who have always enough to carry with them in the way of books and the like, are relieved from the inconvenience of carrying a separate T-square, while the Tsquare itself is subjected to no risk of injury during such carriage.

In the accompanying drawings, in which I have shown a pen or pencil box of this kind, Figures l, 2, and 3 are different views showing the pen or pencil box having an inclosed T -square blade. Fig. 4. shows the device ready for use as a T-square. Fig. 5 is a section on the line 0o cc, Fig. 4..

The pen-or pencil box d, which can be closed by means of the usual sliding lid b, providedl bottom pieces of thebox is so proportioned that the rule or blade c of the Tsquare can be placed therein in a folded condition, for which reason it will be understood that the said blade or rule, after being folded together, should not be longer than the pen or pencil box a.

Vhen it is desired to convert a pen or pencil box of this kind into a T-square, the folded blade or rule o is drawn out of the case, and, aft-er being unfolded, is inserted into flat slots f, formed in the side walls of the case a. The T-square is then ready for use.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

A pen or pencil box which can also be used as a T-square, the said box being provided for this purpose with a rule or blade which may be inserted into slots in the side walls of the said box, and, when not required for use, can be folded together by means of one or more hinges and placed in a space provided between two bottom pieces of the said box, substantially as, and for the purposes, hereinbefore described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
