page_text: I JOHN HUSBAND of Charbagh Lucknow in the Province of Oudh in the East
Indies Loco foreman on the Oudh and Rohilcund Railway do hereby declare the
nature of my said Invention for "AN APPENDAGE OR TRINKET COMBINING ▲
THERMOMETER AND MAGNIFYING LENS WITH THE HOLDER WHICH MAY BE IN THE
FORM OF A PENCIL CASE OR A LOCKET OR CHARM " to be as follows:-
My Invention has for its object a convenient and useful pendent or trinket to be
attached to or worn on a watch chain or the like and it consists in combining a
Thermometer and magnifier with a Pencil Case Locket or other Trinket such as is
usually worn at the end of a watch chain.
In carrying out my Invention with reference to a pencil case for example within
the outer case is fitted to slide a thick tube of glass in the bottom end of which is
formed the bulb of the Thermometer This bulb may be protected from injury by
a piece of wood or other suitable material fitted neatly into the pencil case.
When the tube is of a cylindrical form one side thereof may be ground flat to
receive the index which may be cut in it. The Thermometer may however be of
the ordinary type provided with a protecting case having slots through which the
mercury tube may be seen and on this protecting case the index may be cut
stamped or fixed.
A ring or frame fitted with a magnifying lens is hinged to the end of the outer
case which ring when closed on to the end of the case just clears the top end of the
Thermometer tube. A half ring is fitted to the end of the thermometer tube by
which to connect it to a watch chain or the like.
When it is desired to ascertain the degree of temperature the ring carrying the
magnifying glass is pushed open and the thermometer drawn out.
The height of the mercury in the tube as indicated by the index may then
be readily seen through the magnifying lens which is situated opposite the said
index.
The opposite end of the case may contain a pencil or a watch key and may be
made in a separate piece fitted on underneath the Thermometer.

page_text: When my Invention is applied to a locket or the like the Thermometer tube is
arranged in the case in the form of volute the mercury bulb being by preference
in the middle of the case and the tube wound round it.
The back of the case may be of metal with the index cut stamped or pasted
on it, or the index may be cut on the flat glass forming the front of the locket.
The glass face is arranged in front of the Thermometer tube and fits into a ring
in the body of the locket and a magnifying glass may replace the ordinary flat
glass the index being in this case on the back plate.

page_text: I JOHN HUSBAND of Charbagh Lucknow in the Province of Oudh in the East
Indies Loco Foreman on the Oudh and Robilcund Railway do hereby declare the
nature of my invention for "AN IMPROVED APPENDAGE FOR WATCH CHAINS AND
OTHER ARTICLES OF JEWELLERY "and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:
My Invention has for its object to provide a convenient and useful appendage or
trinket for attachment to a watch chain or the like and it consists in combining a
thermometer and if needed also a magnifying glass with a pencil case watch key
locket or other trinket such as is usually attached to a watch chain.
I will describe my Invention with reference to the accompanying drawings,
Figure 1 of which is a longitudinal Section and Figure 2 an external view of a
thermometer combined with a holder of a pencil watch key or other article, and
fitted to slide in an outer case A having at the end a a magnifying glass-The
thermometer tube B which is preferably of thick glass is fitted to slide in the outer
casing A and is formed with the bulb b and space 6 containing the mercury or
indicating liquid of the thermometer the degrees of which are marked on the tube
or on a slip attached thereto. The tube B may however be of metal or other
material containing the thermometer bulb and tube and slotted so that the mercury
of the thermometer can be observed.
The bulb may be protected from injury by a piece of wood or other suitable
material fitting into the case When the tube is of a cylindrical form one side
thereof may be ground flat to receive the markings indicating degrees of tempera-
ture. To the outer case is hinged a cover b³ containing a magnifying lens which
cover when the tube B, is within the tube A can be shut down to secure the parts
in position as shewn in Figure 1 When opened it stands in line with the case A
and serves as a magnifying lens to enable the markings of degrees on the tube B.
to be easily read when the said tube is withdrawn as shewn in figure 2. C is
a hoop or ring secured to the part A for attaching to it the watch chain or the
like.
When it is desired to read the indication of the thermometer the cover 63 is
opened and the thermometer is drawn out as shewn in Figure 2 and the height of
the mercury in the thermometer tube may then be easily read through the
magnifying lens.
The lower part of the case containing or carrying the pencil, watch key, or the
like, may be formed in one with the case A or tube B or it may be made separately
and be fixed thereto.
Whilst not limiting myself to any particular form of the trinket I have shewn
in the drawing a groove cut in the end of the tube B for the purpose of inserting
and holding the taper end in which the pencil watch key or the like is held.
Figure 3 shews my Invention applied to a locket, the thermometer being
arranged in the locket case in the form of a volute, the bulb being preferably in the
centre and the tube arranged spirally round it. The back of the case has the

page_text: degrees marked thereon, or affixed thereto as shewn, or the degrees may be cut on
the glass front of the locket. Or the said glass front may be a magnifying lens to
enable the markings of degrees on the back of the case to be readily read. The
other side of the locket, may hold a photograph or be utilized for containing other
desired article.
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
First: An appendage consisting of a pencil or watch key holder or case or the
like with which is combined a thermometer substantially as hereinbefore described
and illustrated by Figures 1 and 2 of the accompanying drawings.
Second: An appendage consisting of a pencil or watch key holder or cover or
the like with which is combined a thermometer and a magnifying lens substantially
as hereinbefore described and illustrated by Figures 1 and 2 of the accompanying
drawings.
Third-An appendage consisting of a locket with which is combined a ther-
mometer arranged as a volute or spiral substantially as herein before described and
illustrated by figure 3 of the accompanying drawings.
