page_text: I, JOSEPH THURNAUER of 66 Rue de Bondy Paris France Merchant do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in or additions to ordinary pocket knives
by combining therewith a coiled tape spring measure and a gauge or measuring rod
(one or both) the latter being used for measuring thickness or diameter.
In applying a measuring tape to the handle of a pocket knife in accordance with
my invention the handle is enlarged at the end to admit of the mounting thereon
of an ordinary tape measure advantageously made of a narrow strip of metal which
when drawn out and released is self coiling to close up into its case by means of a
coiled spring combined therewith.
When a gauge or measuring rod is also combined with the handle of a pocket
knife in addition to the measuring tape previously described in accordance with my
invention one is arranged on one side at the end of the handle and the other on
the other side both on the one end of the knife.
The measuring rod slides in a recess or slot formed in the cheek or side plate of
the handle which thus serves to guide the rod as it is drawn out or pressed back.
The graduated rod at its outer end is furnished with a projecting flat surface at
right angles to the graduated bar or rod this flat surface fits up against a corre-
spondingly flat surface formed on the end of the handle and when the graduated
bar or rod is drawn out it is between these two surfaces that the object to be
gauged or measured is placed.
The inner end of the graduated bar or rod is provided with a stud or projection
to prevent the rod from being drawn out too far.

page_text: I, JOSEPH THURNAUER of 66 Rue de Bondy, Paris, France, Merchant 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 improvements in or additions to ordinary pocket knives
by combining therewith a coiled tape spring measure and a gauge or measuring rod
(one or both) the latter being used for measuring and gauging the thickness or
diameter of various forms of articles.
In applying a measuring tape A as shown in the drawing hereto annexed to the
handle of a pocket knife in accordance with my invention the handle is advan-
tageously enlarged at the end to admit of the mounting thereon of an ordinary
tape measure advantageously made of a narrow strip of metal A which when
drawn out and released is self coiling to close up into its case by means of a coiled
spring combined therewith.
When a gauge or measuring rod is also combined with the handle of a pocket
knife in addition to the measuring tape previously described in accordance with
my invention one is arranged on one side at the end of the handle and the other
on the other side both on the one end of the knife as represented in Figures 1 and 2
of the drawings hereto annexed. Either the tape A or the gauge a may be applied
to a pocket knife alone.
The measuring rod a (advantageously formed with a bevelled edge or edges)
slides in a recess or slot formed in the cheek or side plate of the handle (as shown
by the transverse sectional plan Figure 3) which thus serves to guide the rod a as
it is drawn out or pressed back into the handle.
The graduated rod a at its outer end is furnished with a projecting flat surface a¹
at right angles to the graduated bar or rod a this flat surface fits up against a
correspondingly flat surface a formed on the end of the handle and when the
graduated bar or rod is drawn out it is between these two surfaces that the object
to be gauged or measured is placed.
A
By this arrangement the measure a can be used for measuring the diameters of
cylinders round rods and, wires also of spheres, balls, discs and buttons in fact the
rod acts as a gauge as well as a measure.
The inner end of the graduated bar or rod a is provided with a stud or projection
to prevent the measuring rod and gauge from being drawn out too far.
The measuring rod and gauge a may be applied to a pocket knife in various
ways in accordance with my invention and Figure shows a measuring gauge a
applied to the handle in like manner to the blade of a pocket knife as will be
clearly understood by examining the drawing.

page_text: 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:
1. The improved arrangement and construction of a pocket knife having a
measuring tape A combined therewith substantially as herein before described.
2. The improved arrangement and construction of pocket knives having a
measuring tape A and a measuring gauge or rod a combined therewith substan-
tially as described with reference to the drawings hereto annexed.
