WILLIAM ROBERT LAKE, of the firm of Haseltine Lake and Co., Patent
Agents, Southampton Buildings London. "AN IMPROVED TOOL, OR IMPLEMENT
DESIGNED TO SERVE AS A SPANNER OR PIPE-CUTTER OR FOR SIMILAR PURPOSES"
[A communication to him from abroad by Georges Louis Eusèbé Duhayon, of Paris,
France.]
This Invention relates to an improved multiple tool capable of various applica-
tions as hereinafter set forth.
By the said Invention I am enabled to provide, amongst other things, an
improved spanner presenting great advantages as regards facility of manipulation
over the spanners ordinarily in use. It will be seen moreover, that by the substi-
tution of a single piece I can convert the spanner into a pipe-cutter, simple and
efficacious in all its applications, or I can adapt it to serve as a tool for other
purposes.
In order that the said Invention may be readily understood, I have represented
in the accompanying Drawings by way of example, one of the improved tools.
Figure 1 represents a side elevation of the improved spanner, which, without any
modification, may be employed as a pinching-bar.
Figure 2 is a front view of the same..
Figure 3 represents the tool arranged to serve as a pipe-cutter.
Figure 4 is a front view of the same

page_text: Figure 5 is a perspective view of the spanner and
Figure 6 represents two detached views of the piece to be substituted to convert
the spanner into a pipe-cutter.
In these Figures like letters indicate the same parts.
As will be seen more particularly in Figures 1, 2, and 5, the improved spanner is
composed essentially of a piece a of cast iron or other suitable material, one of the
two horizontal arms of which forms the nut b of the screw c and the other arm the
upper fixed jaw d of the spanner. The vertical part of the piece a is provided with
a ribe which forms a guide and upon which slides the movable jaw ƒ of the
spanner. This movable jaw is secured upon the extremity of the screw c by means
of a pin g. The two jaws d and f of the spanner are formed with an angle in such
a manner as to facilitate fitting the spanner upon six sided nuts by simply adjusting
the movable jaw f. The tool as represented in Figure 1, can be used as a pinching-
bar by bearing the extremity of the fixed jaw d under the piece to be raised.
The rib e at its lower part, is made with grooves or notches h. When it is
desired to convert the spanner into a pipe-cutter the movable jaw fis caused to
descend as far as the lower extremity of its stroke, the pin g is then withdrawn, and
the jaw fis disengaged from the piece a, the teeth i upon this jaw as well as upon
the piece holding the cutting roller of the pipe-cutter (Figure 6) when in this
position being opposite the said grooves or notches, thus permitting the one piece to
be withdrawn and the other to be substituted for it.
The cutting roller or disc k (Figure 6) the fitting of which upon the rib of the
piece a and on the extremity of the screw c permits of converting the spanner into
a pipe-cutter, is mounted as above described with reference to the movable jaw of
the spanner; the pipe to be cut is gripped between the upper jaw d and the
roller k and is rapidly cut whatever be its resistance, by imparting some cutting
movements to the tool.
.
If desired, a 'rod may be fixed parallel to the rib e to serve as a guide for the
movable jaw or the piece carrying the cutting roller. The piece a may be
articulated, by a hinge or other suitable means, upon its lower horizontal arm, in
order to facilitate the, release of the tool without the necessity for lowering the
screw to the end of its stroke.
The form and arrangement of the spanner and pipe cutter may be varied
according to the size and kind of nuts for which the former is to be used, and the
nature and diameter of the pipes to be cut by the latter; the characteristic
feature of my Invention being the detachability of the lower jaw of the spanner, I
may apply it, or convert it, in other manners than those above described, by replacing
this detachable part and substituting for it any other device to form a special tool.
I may also apply to the improved multiple tool as a handle, any suitable device for
facilitating the oneration of the so
gerow

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London "AN IMPROVED TOOL OR IMPLEMENT DESIGNED
TO SERVE AS A SPANNER OR PIPE-CUTTER OR FOR SIMILAR PURPOSES" A com-
munication' to me from abroad by Georges Louis Eusèbe Duhayon of Paris

This Invention relates to an improved multiple tool capable of various applica-
tions as hereinafter set forth.
"
By the said invention I am enabled to provide, amongst other things, a spanner
presenting great advantages, as regards facility of manipulation, over the spanners
ordinarily in use. It will be seen, moreover, that, by the substitution of a single
piece, I can convert the spanner into a pipe-cutter, simple and efficacious in all
its applications.
In order that the said invention may be readily understood, I have illustrated in
the accompanying drawing, by way of example, one of the said tools.
Figure 1 is a side elevation of the improved spanner.
Figure 2 is a front view of the same.
Figure 3 shows the tool arranged to serve as a pipe-cutter.
Figure 4 is a front view of the same
2',
Figure 5 is a perspective view of the spanner, and
:
Figure 6 represents two detached views of the piece which is substituted in order
to convert the spanner into a pipe-cutter.
Similar letters of reference indicate corresponding parts in the several figures.
As will be seen more particularly in Figures 1, 2 and 5; the improved spanner is
composed essentially of a piece a of cast or wrought iron or other suitable material,
one of the two horizontal arms of which forms the nut b of the screw c, and the
other arm the upper fixed jaw d of the spanner. The vertical part of the piece a
is provided with a rib e which forms a guide, and upon which slides the movable
jaw f of the spanner. This movable jaw is fitted upon the extremity of the screw c
by means of a pin g. The two jaws d and f of the spanner are formed with an
angle of about sixty degrees, so as to facilitate the unscrewing of six sided nuts by
simply pushing the movable jaw f forward. The tool as represented in Figure 1,
can be used as a pinching-bar by bearing the extremity of the fixed jaw & under
the piece to be raised.
The rib e is provided at its lower part with notches h. When it is desired to
convert the spanner into a pipe-cutter, the movable jaw fis caused to descend as
far as the lower extremity of its stroke, the pin g is then withdrawn, and the said
jaw fis disengaged from the piece a, the teeth i upon this jaw as well as upon the
cutting roller of the pipe-cutter (Figure 6) when in this position, being opposite
the said notches and thus permitting the one piece to be withdrawn and the other
to be substituted for it.
The cutting roller or disc k (Figure 6), the fitting of which upon the rib of the
piece a, and on the extremity of the screw c, permits of converting the spanner
into a pipe-cutter, is mounted as above described with reference to the movable
jaw of the spanner; the pipe to be cut is gripped between the upper jaw d and the
roller k and is rapidly cut through, whatever may be its resistance, by imparting
some suitable movements to the tool.
If desired, a rod may be fixed parallel to the rib e to serve as a guide for the
movable jaw or the piece carrying the cutting roller. The piece a may be

page_text: articulated, by a hinge or other suitable means, upon its lower horizontal arm in
order to facilitate the release of the tool without the necessity for lower ng the
screw to the end of its stroke.
The form and arrangement of the spanner and pipe cutter may be varied
according to the size and kind of nuts for which the former is to be used and the
nature and diameter of the pipes to be cut by the latter. The characteristic feature
of the invention being the detachability of the lower jaw of the spanner. I may
apply it or convert it in other manners than those above described, by replacing
this detachable part and substituting for it any other device to form a special tool.
I may also apply to the improved multiple tool, as a handle, any suitable device for
facilitating the operation of the screw.
Having thus fully described the said invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim

First. In a tool which may be used either as a pipe-cutter or a spanner, the
arrangement of the double-armed piece a having the rib e provided with the
notches h to allow of the alteration of the said tool, substantially as described and
for the purpose set forth.
Second. The improved tool formed with a movable part f sliding upon the rib e
of the part a, substantially as described and for the purpose set forth.
Third. The combination, with a tool formed with a piece a and a handle acting
as a nut, of a cutting roller or circular knife supported by a removable-piece having

piece a, substantially as described and for the purpose set forth.
In witness whereof I the said William Robert Lake have hereunto set my
hand and seal this Ninth day of June in the year of our Lord One
