Improvements in or connected with Tools, such as Hatchets, Adzes,
Saws, Vices, and the like.
I, HENRY PORT, of 31, Boulevard Henri IV., Paris, in the Republic of France,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or connected with tools such as
hatchets, adzes, saws, and the like, whereby the holder can be quickly and firmly
affixed to a pick, adze-head, hatchet-head, saw or the like as may be required.
The improved holder can also be combined with the two jaws of a vice in the
manner hereinafter described.
In carrying out the invention the holder is constructed with two jaws connected
together by a screw and two guides, which guides while compelling the movable
jaw to move parallelwise maintain constant the distance between the other jaw and
a socket piece; one of the guides is a simple cylindrical rod passing with slight
frictional contact through the movable jaw and whose two ends are located one in
the fixed jaw and the other in the socket piece. A guide which also passes with
slight frictional contact through the movable jaw is provided at its upper part with
a screw-head which is located in the fixed jaw; its lower end is provided with a
screw-thread corresponding with a screw-threaded recess in the socket-piece.
A screw, the upper smooth end of which turns freely in the fixed jaw, operates
the movable jaw; at its lower part the screw has a shoulder beneath which are a
cylindrical part and a square part. The square part is provided with a cut-away
portion and a projection. To this projection which forms a hook is adapted the
end of a square rod which serves as a core for the handle by which the movement
of the holder is effected. For this purpose the square part is kept against the rod
by means of a socket having a square opening; this socket is provided at its lower
part with a cylindrical part forming a ferrule on the handle which is also held by
a cap secured by a nut.
A set-screw in the socket piece serves to regulate the position of the screw which
operates the movable jaw.
From this description the operation of the holder will be easily understood and
I will now describe by reference to a hatchet-head the manner in which by special
arrangements, the said holder can be generally adapted to a series of tools such as
an adze, a saw, etc. etc.
It is to be understood that these tools are given as examples only and can be
replaced by others.
The back of a hatchet-head is provided with a double stop having a solid part
terminating in a fork, the opening of which corresponds exactly with the diameters
of the hereinbefore described guides; on the solid part is a small tenon corresponding
exactly with an opening formed in the fixed jaw. It will be understood that if the
solid part is introduced between the jaws of the holder, the guides will take into
the fork and the tenon into the opening; on the handle being then tightened up a
hatchet will be obtained which will be absolutely rigid and firm. The operation
having thus been described with reference to a hatchet it will be unnecessary to
describe it with reference to various other tools, the operation being effected in
precisely the same manner.
I will now describe the arrangement employed for a parallel vice which
necessitates a special construction of the vice.
The fixed jaw of the vice is hollowed out to receive the fixed jaw of the holder;
it is provided at its lower part with a circular plate which rests on a bench.

page_text: clamp, provided with a regulating screw and having a fork, presses the plate
against the bench and holds the fixed jaw of the vice firmly in position. The fixed
jaw of the holder is rendered immovable in the fixed jaw of the vice by means of
a set-screw. The movable jaw of the vice receives the movable jaw of the holder
which is fixed in position by a screw-pin passing through it. The vice may be
operated either by the handle of the holder as hereinbefore described or by means
of a hexagonal ferrule. This latter arrangement is provided in consequence of the
inconvenience which might arise from the handle being placed in front of the bench.
The handle being removed I take a hexagonal spanner corresponding to the
ferrule; this spanner is provided with a screw-thread which allows of a handle
being adapted thereto; the tail of the spanner has its end thinned to form a screw-
driver.

COMPLETE SPECIFICATION.
Improvements in or connected with Tools, such as Hatchets, Adzes,
Saws, Vices, and the like.
I, HENRY PORT, of 3 Avenue Philippe Auguste, Paris, in the Republic of
France, Mechanical Engineer, 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 connected with tools such as
hatchets, adzes, saws and the like, whereby the holder can be quickly and firmly
affixed to a pick, adze-head, hatchet-head, saw or the like as may be required.
The improved holder can also be combined with the two jaws of a vice in the
manner hereinafter described.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing, in which :-
Figure 1 is an elevation of the handle or holder:
Figure 2 is a vertical section:
Figure 3 shews the handle adapted to a hatchet head:
Figure 4 is a plan of Figure 3:
Figure 5 shews the handle adapted to an adze-head:
Figure 6 is a plan of Figure 5:
Figure 7 is an elevation of a saw :
Figure 8 is an edge view of Figure 7:
Figure 9 shews the two jaws of a vice adapted to the two jaws of the improved
holder and fixed to a benchi by a clamp:
Figure 10 is a vertical section of the two jaws of the vice shewing the position
of the two jaws of the improved holder:
Figure 11 is a view of a hexagonal spanner, the handle of which can be used as
a screw-driver and serving to operate the movable jaw of the vice when the handle
of the holder is removed :
Figure 12 is an elevation of the jaw of the vice fixed to the bench :
Figure 13 is a view of the movable jaw of the vice:
Figure 14 is an underside view of the movable jaw :
Figure 15 is an end view of the clamp for fixing the vice to the bench.
In Figures 1 and 2 A and B are two jaws connected together by a screw C and
two guides G, H; which guides G, H while compelling the movable jaw B to move
parallelwise maintain constant the distance between the jaw A and a socket piece D;
the guide G is a simple cylindrical rod passing with slight frictional contact
through the movable jaw B and whose two ends are located one in the fixed jaw A

page_text: and the other in the socket piece D. A guide H which also passes with slight
frictional contact through the movable jaw B is provided at its upper part with a
Screw-head which is located in the fixed jaw A ; its lower end is provided with a
screw-thread corresponding with a screw-threaded recess in the socket piece D.
A screw C the upper smooth end g of which turns freely in the jaw A operates
the movable jaw B; at its lower part the screw C has a shoulder h beneath which
are a cylindrical part k and a square part 1, (the parts hand k turn with slight
frictional contact in the opening formed for this purpose in the socket piece D).
The square part is cut away at m and has a projection n. To this projection n,
which forms a hook, is adapted the end of a square rod E which serves as a core
for the handle J by which the movement of the holder is effected.
purpose the square part is kept against the rod E by means of a socket I having
a square opening; this socket is provided at its lower part with a cylindrical
part I forming a ferrule on the handle J which is also held by a cap K secured by
a nut F which screws on the lower end of the square rod E.
For this
A screw L in the socket piece D serves to regulate the position of the screw C
which operates the movable jaw.
From this description the operation of the holder will be easily understood and
I will now describe by reference to a hatchet head the manner in which by special
arrangements the said holder can be generally adapted to a series of tools such as
an adze, a saw, parallel vice, etc. etc.
It is to be understood that these tools are given as examples only and can be
replaced by others.
Referring to Figures 3 and 4 at the back of a hatchet head M is a double
stop a, a having a solid part N terminating in a fork N, the opening of which
corresponds exactly with the diameters of the guides H and G; on the solid
part N is a pin corresponding exactly with an opening formed on the jaw A.
It will be understood that if the solid part N' is introduced between the jaws of
the holder, the guides will take into the fork N and the pin & into the opening b¹;
on the handle being then tightened up a hatchet will be obtained which will be
absolutely rigid and firm. The operation having thus been described with reference
to a hatchet it will be unnecessary to describe it with reference to the various
tools shewn in the drawings, the operation being effected in precisely the same
manner.
I will now describe the arrangement employed for a parallel vice which
necessitates a special construction of the vice.
The
Figure 12 shews the fixed jaw O of the vice which is hollowed out (as shewn
in Figure 10) to receive the fixed jaw A of the holder; it is provided at its lower
part with a circular plate X which rests on a bench. A clamp U provided with a
regulating screw e, and having a fork V (Figures 9, 10 and 15) presses the plate X
against the bench and holds the fixed jaw of the vice firmly in position.
fixed jaw A of the holder is fixed in the jaw O by means of a set screw c. The
movable jaw P of the vice (Figures 9, 10 and 13) receives the jaw B (Figure 10)
which is fixed in position by a screw-pin d. The vice may be operated either by
the handle J of the holder as hereinbefore described or by means of a hexagonal
ferrule (Figures 1, 9 and 11). This latter arrangement is provided in
consequence of the inconvenience which might arise from the handle being placed
in front of the bench. The handle being removed I take a hexagonal spanner R
(Figure 11) corresponding to the ferrule I'; this spanner is provided with a
screw-thread which allows of a handle S being adapted thereto; the tail Q of the
spanner has its end T thinned to form a screw driver.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. A holder or handle for tools such as hatchets, adzes, saws, vices and the
like consisting in an arrangement of jaws and guides adapted to be combined with

page_text: tools of suitable construction, whereby the handle or holder can be rapidly adapted
and fixed to any particular tool, substantially as herein before described.
2. The improvements in holders or handles for tools such as hatchets, adzes,
saws, vices and the like and in the tools or tool-heads to be combined therewith
hereinbefore described and illustrated in the accompanying drawing.
