GAUGE FOR- NIPPLE CUTTERS
John F. Dahl, Palo Alto, Calif.
Application August 21, 1935, Serial No. 37,219
2 Claims. (Cl. 33—185)
This invention relates to a gauge for pipe or
nipple cutter, the general object of the inven
tion being to provide a graduated bar adapted to
be connected to the shank part of a cutter be
5 tween the cutting jaws thereof with an adjustable
stop bar on the gauge bar which determines the
length of pipe or nipple to be cut.
This invention also consists in certain other
features of construction and in the combination
10 and arrangement of several parts, to be herein
after fully described, illustrated in the accom
panying drawing and speci?cally pointed out in
the appended claims.
In describing the invention in detail, reference
15 will be had to the accompanying drawing where
in like characters denote like or corresponding
parts throughout the several views, and in
which:
Figure 1 is an elevation showing the invention
20 applied to a cutting tool.
Figure 2 is a front elevation of the device.
Figure 3 is a detail view of the sections of the
graduated bar.
bar 3 will extend in spaced relation across the
pipe receiving base of the cutter and thus will
form a stop for the end of the pipe to be cut so
that by properly adjusting the bar 3 on the bar
I the pipe can be cut to the required length and
when a number of lengths are to be cut all of
the equal length the bar 3 may be placed and
the pipe is moved forwardly until the end is
placed against the bar 3 and then the pipe is
10
cut.
To compensate for the thickness of the cutter
in accurately cutting the work, a spring-pressed
section I is provided on the graduated bar, which
is adapted to move outwardly as the thickness of
15
the cutters increase.
It is thought from the foregoing description
that the advantages and novel features of the in
vention will be readily apparent.
It is to be understood that changes may be
made in the construction and in the combination 20
and arrangement of the several parts, provided
that such changes fall within the scope of the
appended claims.
What is claimed is:
In these views the letter A indicates a cutting
tool
which may be of hand or power type and
25
which has the usual cutters a extending into the
space between the two jaws thereof.
In carrying out my invention I provide a grad
uated bar which is made up of sections I and I’.
30 Section I is provided at one end with a pin 6,
1. A gauge for cutting implements comprising 25
a threaded member adapted to be screw-threaded
into the emplement, an elongated section pro
vided with a reduced extension, said threaded
member having a bore therein for slidably receiv
ing the reduced extension, 2. spring connection 30
section I’ is threaded into a hole formed in a
section, a slidable gauge member on the elongated
section, and means for ?xing the slidable mem
ber in de?nite positions on the elongated sec
35
tion.
which is adapted to loosely ?t into the opening
‘I of section I’ to join said sections. One end of
side of the shank of the tool slightly in front of
35 the stationary jaw of the cutter, the section be
ing held in place by a nut 2. Grooves 8 and 9
are formed adjacent one of the ends of each
section I and l’ respectively to receive the ter
minals of the coil spring I0. Accordingly, with
40 section I’ attached to the stationary jaw of the
cutter, section I is adapted to be moved outward
ly, and to be retracted to its normal position,
as shown in Figure 2, by the spring III.
A stop forming bar 3 has an enlargement 4
45 thereon which has a hole passing therethrough
through which the section I of the graduated
bar passes. A set screw 5 passes through the ad
jacent end of the bar 3, which has a threaded
socket therein intersecting the opening on the
50 bar, the inner end of the screw being pointed to
engage any desired one of the row of counter
sunk depressions I I formed in the section I of the
graduated bar.
55
Thus when the device is in place the stop
between the threaded member and the elongated .
2. A gauge for cutting implements comprising
a threaded member adapted to be screw-driven
into the implement, an elongated section pro
vided with a reduced extension, said threaded
member having a bore therein for slidably re 40
ceiving the reduced extension, a spring connec
tion between the threaded member and the
elongated section, a slidable gauge member on
the elongated section, and means for ?xing the
slidable member in de?nite positions on the 45
elongated section, said spring being of coiled con
struction, both said threaded member and
elongated section being provided with a circum
ferential groove for receiving the corresponding
end convolution of the spring, said spring being 50
adapted to retain the threaded member and
elongated section in end to end abutting relation.
