Complete Specification Left, 29th Apr., 1896-Accepted, 27th June, 1896
PROVISIONAL SPECIFICATION.
Tool for Gauging Depth of Hollows, Flat Bottomed Depressions, and”.
the like.
GUSTAVE EMILE CORNIOLEY of 26 and 27 Bartlett's Buildings Holborn Circus
London E.C. and CHARLES SYLVAIN MAIRET, of same address Horologist, do
hereby declare the nature of this invention to be as follows:-
The tool consists of
1.) A flat piece of metal (marked A in drawing) one end of which has the shape.
of a sector with divided scales, while at D it has a projection as shown.
2.) A hand or indicator B moving friction tight on C as center; this hand B.
has also a projection corresponding to D, but on the same is fixed a heel E working
close to and in the same plane as projection D, a slot F is cut in the flat piece A to.
allow the heel E free passage through it.
The mode of action is as follows:
The tool being held in the hand, the heel E is placed on the edge of the hollow
to be measured, a slight pressure causes projection D to sink into the hollow-
carrying the hand B with it which then registers the depth on the divided scales.

Horologist 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 :-
The above tool consists of 1) A flat piece of metal marked A (as per drawing left
with the Provisional Specification) one end of which has the shape of a sector with
divided scales, while at D it has a projection as shown. 2) A hand or indicator B
moving on the surface of above plate friction tight on C as center; this hand B has
also a projection corresponding to the one on the plate marked D, but on which is
fixed a heel E working close to and in the same plane as projection D; a slot F is
cut in the flat piece A, to allow the heel E free passage through it.
The working parts of the lateral projections have the shape of part of a circle
the centre of which is that of the indicator as well as that of the sector with divided
scales on the plate. These working parts can be arranged on either side of the
1rojections. The lateral projections can be at any distance between centre and
cud of indicator and of plate and at any convenient angle to suit the objects and
dimensions that are to be gauged by the tool.

page_text: The mode of action is as follows:
The tool being held in the hand, the face of heel E is placed on the edge of
the hollow to be measured. A slight pressure causes projection D to sink into
above hollow carrying with it the hand B which then registers the depth on the
livided scales.
Having now described the new tool and its working, we declare the invention
claimed by us to consist of the following combination:
An indicator having a lateral projection at a convenient distance between centre
and end and at a convenient angle, and being moveable friction tight upon a plate
one end of which-corresponding with the point or points of the inilicator-has
the shape of a sector with divided scales and there being on the said plate-
corresponding with the lateral projection of the indicator-a similar lateral
projection; one side of both projections forming part of a circle having for its
centre the centre of the indicator; a heel fixed to the circular shaped side of
one of the projections working in a slot close against the edge of the circular
shaped side of the other projection.
Dated this Twenty-ninth day of April 1896.
