COMPLETE SPECIFICATION.
A Combined Adjustable Spanner and Pipe-wrench.
I, FRITZ NIKLES, of 10, Neuengasse, Berne, in the Republic of Switzerland,
Gentleman, 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 a combined adjustable spanner and pipe-wrench.
Adjustable spanners as hitherto usually made cannot be employed as pipe-
wrenches as the gripping surfaces of their jaws are always parallel to one another
and cannot therefore be used for turning a pipe. Now, in the adjustable spanner
forming the subject of this invention one of the jaw surfaces can be brought from
its parallel position to any suitable inclination with respect to the other jaw surface
so that the spanner can also be employed as a pipe-wrench.
The accompanying drawing shews a spanner constructed according to the
invention; in the said drawing-
Figure 1 is a sectional side elevation of the tool the two jaw surfaces being
shewn parallel to one another as in an ordinary adjustable spanner or screw
wrench:
Figure 2 is a side elevation of the head of the spanner shewing the lower jaw
inclined to the upper jaw whereby the tool can be used as a pipe-wrench:
Figure 3 is a section on the line - Figure 1:
Figure 4 is a section on the line y-y Figure 1: and
Figure 5 is a section on the line
Figure 2.
From the upper jaw A of the spanner there extends at right angles thereto and in
a downward direction a limb or extension B which is provided with a longitudinal
slot 6 and passes into the handle 60. The lower jaw C is adjustably arranged in
such a manner that it can be moved towards or away from the upper jaw A as
ordinarily and also so that its gripping surface can be brought to any suitable
inclination with respect to the jaw A.
In the jaw C, which is provided with a guide Co, there is loosely mounted a
serew D formed with a head d, the upper end of the said screw D being provided
with an annular groove do with which engages a pin co passing through the lower
jaw C in such a manner that the said screw ]) is connected to the jaw C whereby
when the screw is turned the jaw is moved in the direction of its axis. The
screw I passes through a guide piece E which pivoted to the limb B at a point
below the slot b by means of a pin or pivot o the said guide piece being provided
with an internal screw-thread and being formed with an extension e which engages
in a longitudinal groove c in the guide Co so as to serve as a guide therefor.
The jaw C is provided with an extension i arranged at right angles to the axis
of the screw D; the said extension i is passed loosely through the slot 6 in the
limb B and the end which projects through the said slot is provided with a rotatable
button or knob F. This button is provided with two wings f,f adjacent to the
limb B and having a thickness somewhat less than the width of the slot b.
It will be obvious from the foregoing description that when, as shewn in Figure 1,

page_text: the wings f,f of the button F are adjusted transversely to the slot 6 of the limb B
and the screw D is turned in the nut E the jaw C can only be raised and lowered,
the gripping surfaces of the jaws remaining parallel to one another as is usual in
ordinary adjustable spanners; if, however, the wings f, f be turned from their
transverse position to a position in which they are parallel to the slot b they can
pass into the said slot, as shewn in Figure 2, and so allow the jaw C to turn with
the guide E upon the pivot o whereby its gripping surface is brought into a
position inclined to that of the upper jaw surface, so that the spanner can be
employed as a pipe wrench. In this case there is obviously no hindrance to the
turning of the screw I) as the guide E turns with the jaw C so that the distance
between the jaws can be adjusted according to the thickness of the pipe to which
the tool is to be applied.
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. A combined adjustable spanner and pipe-wrench wherein the lower jaw is
connected to a guide piece E pivoted to an arm or limb of the upper jaw and which
said guide piece forms the nut for a screw D serving to adjust the lower jaw
which is provided with an extension the end of which is furnished with a rotatable
button Fhaving wings f, the said extension i passing through a longitudinal slot b
in the limb of the upper jaw so that when the wings f are adjusted into a position
parallel to the slot 6 the lower jaw can take a position inclined to the upper jaw
whereby the tool can be employed as a pipe-wrench and when the wings f are
adjusted transversely to the said slot b the lower jaw can only be adjusted parallel
to the upper jaw so that the tool can be employed as an adjustable spanner.
2. The combination and arrangement of parts forming the improved combined
adjustable spanner and pipe-wrench hereinbefore described and illustrated in the
accompanying drawing.
