PROVISIONAL SPECIFICATION.
An Improved Universal Tool-handle or Tool-holder.
1 JOSEPH LILLY of No. 6 Hutton Street, Nechells, in the County of Warwick Art
Metal Worker do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of tool-handles or tool-holders which are made
hollow to contain a number of tools or "bits" and are provided with a clamping
device for securing such "bits" or other tools by their shanks of various sizes.
According to my invention I provide a hollow handle fitted with a cap or cover
at one end. At the other end I secure a metal mounting having a square opening or
hole centrally formed therein. In this square opening I place a tapered square
clamping piece split through part of its length into two portions capable of being
closed together more or less according to the distance to which the tapered square
portion is drawn or driven into the square opening hereinbefore mentioned, through
which it is too large to pass completely. The square clamping piece extends to a sufficient
length to receive the shanks of suitable size tools for the handle and is in its con-
tinuation through the hollow handle reduced to a cylindrical form representing a small
size rod with a screw thread formed at its extremity. In the cap or cover of the
handle a screw nut is fitted to engage with the screw thread on the end of the rod
extending from the square clamping piece. By this means the operation of rotating.
the cap or cover of the tool-handle one way draws the square clamping piece into the
square opening at the opposite end of the tool-handle and thus closes the clamping
piece securely upon the shank of any tool which may liave been placed therein. By
rotating the cap or cover in the opposite direction the clamping piece may be driven
from the square opening at the opposite end of the tool handle and thus the tool may
readily be withdrawn.
For tools having square shanks portions of a square passage are formed inside the
split portions of the clamping piece but these recesses may form portions of a cylindrical
passage to suit tools having cylindrical shanks.

COMPLETE SPECIFICATION.
An Improved Universal Tool-handle or Tool-holder.
I JOSEPH LILLY of No. 6 Hutton Street, Nechells, in the County of Warwick Art
Metal Worker do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to that class of tool-handles or tool-holders which are made
hollow to contain a number of tools or "bits" and are provided with a clamping device
for securing such "bits" or other tools by their tangs or shanks of various sizes.
The accompanying drawings show a tool-handle or tool-holder made in accordance
with my invention.
Figure 1 is an outside view of the complete tool-handle showing the clamping device
released for receiving the tang or shank of a tool.
Figure 2 is a sectional view of the same showing the clamping device closed.
Figure 3 is a view of the clamp removed from the tool-handle and
Figure 4 is a plan of Figure 3.
The hollow handle A is fitted with a cap or cover B at one end. At the other end
secure by a screw c a metal mounting having a square opening or hole centrally

page_text: formed therein. In this square opening I place a tapered square clamping piece D
split through part of its length into two portions E F capable of being closed
together more or less according to the distance to which the tapered square part is
drawn or driven into the square opening in the metal mounting C, through which
it is too large to pass completely. The tapered square clamping piece D will
protrude from the handle A to a suitable distance to open sufficiently to receive the
tang or shank of tools suitable for the handle and is in its continuation through the
hollow handle A reduced to a cylindrical form representing a small size rod with a
screw thread G formed at its extremity.
In the cap or cover B a screw nut H is secured to engage with the screw thread G.
By this means the operation of rotating the cap or cover B of the tool-handle one
way, draws the square clamping piece D into the square opening in the metal
mounting and thus closes the clamping portions E F securely upon the tang or
shank of any tool which may have been placed therein.
By rotating the cap or cover B in the opposite direction the clamping piece D
may be driven from the square opening in the metal mounting C and thus the tool
will be readily withdrawn.
For tools having square tangs or shanks, portions of a square passage are formed
in each of the clamping pieces E and F as shown at Figure 4 but these recesses
may be of cylindrical form to suit tools having cylindrical tangs or shanks.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I, declare that what 1
claim is :-
In a hollow tool-handle or tool-holder a clamping device for securing tools of
various sizes operated by rotating the cap or cover of the hollow handle substantially
as described and illustrated by the accompanying drawings.
