IMPROVEMENTS IN COMBINED POCKET TOOLS
Year: 1884

page_text: I, JACOB LAMERS, of Solingen, in Germany, do hereby declare the nature of
said invention for "IMPROVEMENTS IN COMBINED POCKET TOOLS," to be as
follows:-
This invention relates to combination tools and has for its object to combine
various tools in such a manner that when any of them is in use, the other tools
may form a handle or lever to the same.
For this purpose I pivot two or more tools on a common pin or axle so that each
can be turned independently of the others, but with sufficient friction to retain tho
position into which it has been turned, whether parallel with the other tools or at
any desired angle to the same.
If one of three tools is a cutting tool, for instance a drill, it is placed between
the two others, to prevent it from tearing the pockets in which the tool may bo
carried.
'
I prefer to compose the tool of three principal parts or blades namely a combined
saw blade scale and screw driver, a drill, and a combined file, scale and screw
driver.
The first part is a narrow blade provided with saw teeth on one of its long edges
and a scale or divisions on one of its flat sides, while the narrow edge opposite tho
the pivot is sharpened into a screw driver.
The third part is a narrow blade provided with file cuts or one of its flat sides
as. well as on its long edges, while the other flat side has divisions like & scale, and
the narrow edge opposite the pivot is sharpened into a screw driver.
The boss of each blade is circular and provided with a radial notch forming a
sharp edge, so that the bosses of two contiguous blades act like a wire cutter, if a
wire is introduced and the blades turned against each other.

page_text: I, JACOB LAMERS, Solingen, Germany, do hereby declare the nature of said
invention for "IMPROVEMENTS IN COMBINED POCKET TOOLS," 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 combination tools and has for its object to combine
various tools in such a manner that, when any of them is in use, the other tools
may form a handle or a lever to the same.
For this purpose I pivot two or more tools on a common pin or axle so that each
can be turned independently of the others but with sufficient friction to retain the
position into which it has been turned whether parallel with the other tools or at
any desired angle to the same.
If one of three tools is a cutting tool, for instance a drill, it is placed between
the two others, to prevent it from tearing the pockets in which the tool may be
carried.
In the further description of this invention reference will be made to the
accompanying drawing of which Figs. I and V show two different positions
of a combination tool embodying my invention, while the other figures show in
detail two of the three parts a, b, and c which compose the tool.
As represented, the combination tool comprises two screw drivers of different
width, a saw, a drill, a file and two scales divided into inches and centimetres.
It may also be used as a pair of compasses and as a wire cutter.
The first part or blade a, shown in detail by Figs VII and VIII, has the shapo
of a screw-driver, with a contracted edge a¹ at one end and a circular enlargement
or boss a² at the other end. This boss is perforated in the centre for the reception
of the pivot and is cut out radially at the circumference e in order to act as a wire
cutter.
One of the flat sides of a forms two graduated scales, while the opposite side is
provided with file-cuts.
The second part or blade b, as represented by Figs II and III, is similar to the
first, except that one of its narrow sides forms a saw, and one of its flat sides is
smooth instead of forming a file.
The third part c is a drill placed between the blades a and b, and having also an
enlarged head or boss perforated and provided with a radial notch e like the
blades a and b.
The pin d connecting the three parts has preferably a rivet head on both sides
like the pivot of a pair of compasses.
Fig V shows how the blades a and o of the tool may be used as a pair of
compasses.
As the notches 6, e in the three parts have sharp edges and may be placed in line
with each other or at various angles, the tool will act as a wire cutter if the wire
is laid into the said notches forming a continuous groove parallel to the pivot, and
then one of the blades sharply turned on its pivot.
It is evident that other combinations of tools may be formed, while retaining
the principle of pivoting the tools on a common pin, like the legs of a pair of
compasses.
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 combination of two or more tools adapted to turn on the same axis for
the purpose of forming a handle for that which is in actual use, substantially as
docombed

page_text: 2. A tool composed of a drill and two screw-drivers provided with scales, one of
the said screw-drivers forming a saw while the other forms a file, the three parts
being connected together by one hinge joint and cut out for the purpose of forming
a wire cutter, substantially as described.
