Letters Patent No. 96,366, dated November 2 1869.v

IMPROVEMENT IN PENCIL-ATTACHMEfi T 'I'O COMPASSES.

The Schedule referred to in these Letters Patent and making part of the same.

To allwho'm it may concern.-

Be it known that I, CLARK L. TYLER, of Ithaca, Tompkins county, New York, have invented an Improvement in Attaching Pencils to Dividers, of which the following is a specification.

My object is to make a holder which shall be selfadjustable to the pencil, and also to the leg of the dividers.

Figure 1 is a side view of my pencil-holder;

Figure 2, a section thereof;

Figure 3, a view of the internal variable block; and

Figure 4, sections of this block, and its axis.

In fig. 1, A and B aretwo tubes, one for the pencil and the other for one leg of the dividers, connected the web between the'two tubes, and secured by the pin in the slot G", fig. l, a pencil put in one of the tubes will bear on one of the parts of the block; and when the leg of the dividers is thrust into the other tube, the thrusting in causes the variable block to act, and to hold both pencil and dividers; the oscillation of one ,of the said parts of the block, allowing an adjustment to the varying taper of the compass- ]eg, and the lateral play of the compound block, by its axis in the transverse slot, allowing its adjustment to difi'erenhsizad pencils.

The uses and advantages of my invention are apparent to those skilled in the art to which it appertains. Y

' Claim.

The combination and arrangement of the doubletubed socket A B, united by the open Web 0, with the variable block or frame, formed of the two parts D and E jointed together, the pin or axis of which plays in the transverse slot G of the said web O,-substantially as described.
