Improvements in Tool-holders for Lathes and other Machine Tools.
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation

the nature of this invention, which has been communicated to me by Blau and
Company, of 2, Bauernmarkt, Vienna, Austria, Tool-makers, to be as follows:-
This invention relates to an improved construction of tool holder for disc cutters
and disc chasers.
In carrying out these improvements the end of the tool holder is formed in
U fashion and with two eyes which are concentric with each other and bridged
over the top.
In the said bridged part is a hole adapted to receive the shank of an eye bolt
which is placed between the said eyes. By adjusting the said eye bolt its hole can
be made to coincide with the said eyes and the cutter or chaser disc being formed
with a short shaft which is received by the said eyes and eye bolt, the tool can be
secured in position on the holder by drawing tight the said eyo bolt by means of
its nut.

the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to an improved construction of tool holder for disc cutters

And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. 1 being a perspective view of the
improved tool holder complete and Fig. 2 in parts.
În carrying out these improvements and referring to the figures generally the
tool holder end A is formed in U fashion and in front with two eyes a, a, which
are concentric with each other and bridged over at the top a¹.

bolt b, b', b, which is placed between the eyes a, a. By means of the nut 2 the
svid eye bolt can be adjusted and its eye b' made to co-incide with the eyes a, a.
The cutter or chaser disc is formed with a short shaft which is placed into the
eyes a, a, b, and secured in position on the holder by drawing tight the eye bolt
by means of its nut b².
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
A spring tool-holder, consisting of two eyes a, a, formed at the U shaped end A
of the holder and having an eye bolt b, 61, 62, arranged between the same, the eye b¹
of which bolt by means of its nut 62 is rendered eccentrically adjustable in relation
to the eyes a, a, all substantially as and for the purpose set forth.
