I WILLIAM JOHN PENN of Finsbury Square Buildings 1 & 2 Chiswell Street in
the county of Middlesex Gun Maker do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide a simple and extremely efficient wind-
gauge for use with fire arms which can be carried about very conveniently in the
pocket while it can easily and immediately be applied to the sight of the fire arm.
To carry out this object I mount on a suitable bracket a disc to act as a dial in or
on one part of which disc is fitted a pin or other projection and on this dial as also on
the bracket in the proper corresponding positions are two verniers. The handle of
the bracket is made hollow and the required paint or blacking is contained in this
hollow handle which can be closed by a suitable plug or stopper whereto is attached
a brush or wad which enters the paint or blacking. shoulder is formed on or fitted
to the back of the bracket which can be mado to bear against either or both of the
sides of the sight leaf. The dial can either be revolved by hand in which case it
could be clamped in its required position by a thumb screw or the handle of the bracket
can be made to revolve actuating the dial through a worm or other screw and a pinion or
by other usual or suitable devices or otherwise.
To use this apparatus the dial is set in accordance with the strength of the wind as
indicated on the verniers and when the sight bar is blacked or treated by the brush
or wad contained in the handle the shoulder is pressed against the side of the sight
leaf and moved up or down the same and a line is drawn on the sight bar by the
pin or projection at the desired distance from the centre of the sight which line
indicates the desired angle corresponding to the strength of the wind.

page_text: 1 WILLIAM JOHN PENN of Finsbury Square Buildings 1 & 2 Chiswell Street in
the county of Middlesex Gun Maker 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:—
The object of this my invention is to provide a simple and extremely efficient wind-
gauge for use with fire arms which can be very conveniently carried about in the
pocket while it can also be casily and immediately at any time that may be requisite
applied to the sight of the fire arm.
In the accompanying drawing Figure 1 is an elevation of this my wind-gauge as
and when applied to and being used with and for the ordinary sight of a fire arm
Figure 2 is a plan of the wind-gauge Figure 3 is the brush taken out of the handle of
the same and Figure 4 is an elevation of the end of the wind-gauge.
On a suitable bracket or base A I mount by a pivot a disc B to act as a dial in or
on one part of which disc B is fitted a pin or other projection C near which pin or
projection C and on both sides thereof the pheriphery of the disc B can very con-
veniently be cut away and hollowed out as shewn in Figure 1 for purposes of handling.
On the bracket A in the proper position above the disc B is cut or marked a scale D
and another scale may be cut or marked on the disc B in the proper corresponding
position thus forming a vernier but preferably 1 cut or mark on the disc B as shewn
in Figure 1 only a single contral or zero line. The handle E of the bracket A can
very conveniently be made hollow and the required paint or blacking is contained in
this hollow handle E which can be tightly closed by a suitable plug or stopper F
whereto is attached a brush or wad as shewn in Figure 3 which can enter the paint
or blacking in the hollow handle E. A shoulder G is formed on or fitted to the back
of the bracket A preferably where shewn in the drawing which shoulder G can be
made to bear against the side of the sight leaf or a similar shoulder for the same
purpose may be created at the other end of the bracket A either in addition to or
instead of the shoulder G shewn in the drawing in the former of which cases the
sight leaf would be clapsed or contained between the two shoulders and in the latter
case the bearing aforesaid would be on the other side of the sight leaf but as is
hereinbefore stated I consider the arrangement shewn in the drawing as a general
rule and in the majority of cases the best and most convenient. The disc B can be
revolved or turned on its pivot in and by any usual and suitable manner and appliance
or device preferably simply by hand when as shown in the drawing the finger and
thumb can clasp this disc B on either side of the pin or projection C and the disc B
is so fitted that it can be retained or clamped in any desired position preferably as
shewn in the drawing by a thumb screw nut H on the pivot thereof.
The manner of using this wind-gauge is as follows. The dial B is moved or turned
and set or clamped in accordance with and in reference to the strength of the wind
as indicated on and by the vernier D according to a predetermined scale or method

page_text: of allowance and the wind-gauge is then placed on the sight leaf K in such wise that
the shoulder G according to this form as shown in the drawing is pressed against the
side thereof or according to the other forms herein before described the sight leaf
is clasped or contained between the two shoulders or the wind-gauge is so drawn by
the handle thereof away from the sight leaf that the pressure aforesaid is on
the other side of the sight leaf. The wind-gauge is then moved up and down
or up or down the sight the aforesaid pressure on one of the sides of the sight
leaf K or the aforesaid clasp or containment thereof being maintained and the pin
or projection C therefore draws or causes to be drawn a vertical line on the sight
bar M at the desired distance from the middle or centre thereof which line indicates
the desired angle with the line of the fire arm corresponding to the strength of the
wind and when it is desired to draw another line on the sight bar M it can be if
required treated or blacked by the brush or wad attached to the plug or stopper F
and the aforesaid procedure is repeated.
It is obvious that if the pin C is simply a metallic point the line drawn thereby
on the sight bar M will not necessarily and in all cases be of a different colour to
the adjacent parts of this sight bar and it may oftentimes be desirable if not
absolutely requisite that this line should be of a different colour in which case the
pin or projection C may be formed as shewn in Figures 2 and 4 wherein this pro-
jection is a small short and preferably tapered tube or socket C' wherein and where-
through can be placed and passed a pencil or a piece of lead or chalk or other
substance that will make a white or black or coloured mark and the desired line
is drawn on the sight bar M in manner as hereinbefore described by this substance.
I have thus described and I have shewn in the accompanying drawing
an extremely simple convenient and useful style and form and arrangement of
this my improved wind-gauge for fire arms but I would have it understood that I do
not limit myself exactly thereto for this apparatus and all the several parts thereof
may be made in such styles and of such forms and proportions and may be so
arranged as may be expedient or desirable in each particular case.
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. In a wind-gauge for fire arms the combination of the bracket A with the
shoulder or shoulders G the dial B with the pin or projection C and the vernier D
substantially as and for the purpose hereinbefore described and declared.
2. The combination with the wind-gauge hereinbefore described and claimed of
the hollow handle E and the plug or stopper F with the brush or wad substantially
as and for the purpose hereinbefore described and declared.
3. The wind-gauge for fire arms substantially as hereinbefore described and shewn
in the accompanying drawing.
