I, JOHN ARNOLD, of the firm of Arnold and Sons, of West Smithfield, in the City
of London, Surgical Instrument Maker, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to so construct cases for carrying instruments such
as surgical instruments and other articles, in such manner that they shall practically
be impervious to water and damp.
According to my invention I make the frames preferably of metal, one side of one
such frame being formed with a groove all round same, and the opposite side of such
frame is provided with a tongue, which when the two portions of the case are brought
together, the tongue fits into the groove. The metal frame may be covered with
leather, porpoise hide, seal, and other fish skins, or with any other suitable material,
according to the purpose to which the case is intended to be applied, whether that is
to hold surgical instruments, for which purpose the invention is particularly applicable,
or as a cigar or other case, or for other purposes. As applied to the cases or frames
of bags, the groove would be on one fraine and the tongue on the other, the arrange-
ment being precisely similar to that for the cases with one side hinged; in fact as
regards the cases I prefer connecting the top and bottom together by a leather or other
suitable loose connection.
As applied to instrument, toilet or dressing and other cases which are made of wood,
the groove and tongue may be made in the wood frame, or a metal frame may be fitted
to the wood or other case.

page_text: I, JOHN ARNOLD of the firm of Arnold and Sons, of West Smithfield in the City
of London, Surgical Instrument Makers 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 my invention is to so construct cases for carrying instruments such as
surgical or other instruments, or other like articles, in such manner that they shall
practically be impervious to water and damp.
In order that my invention may be readily understood and easily carried into
practice I will describe the same with reference to the accompanying drawings.
Similar lotters of reference refer to like parts in all the figures.
Figure 1 shews in plan, and opened out, a surgical instrument case, constructed so
as to close practically damp tight according to my invention. Figure 2 is a vertical
section on the line y of Figure 1.; and Figure 3 is a similar section showing the
case in its closed position.
C
According to my invention I make the frames of the cases preferably of metal, one
side a of such frame being formed with a groove ball round same and the opposite
side a of such frame being provided with a corresponding tongue c all round same;
when the two sides of the frame are brought together in order to close the case the tonguec
fits into the groove b. The metal frame may, and that shewn in the drawings is, covered
with leather or porpoise hide, seal and other fish skins, or with other suitable material
according to the purpose to which the case is intended to be applied whether that be
for containing surgical instruments (for which purpose the invention is particularly
applicable) or otherwise.
As applied to the frames of bags the groove b would be on one frame and the
tongue c'on the other, the arrangement being precisely similar to that for the cases
with one side hinged and in fact I prefer connecting the two frames a a' together by a
leather or other suitable loose connection d as shewn at Figures 1, and 2. In the
case shown in the drawings the tongue is made slightly bevelled so as to ensure. a good
and tight fit in the groove as will be best seen at Figures 2 and 3. The side a of the
case is shown provided with flap cover e (shown open at Figure 2) to close or cover
over instruments which are held under straps provided for the purpose and the opposite
side a of the frame is made with an expanding pocket f the outside of which is

page_text: provided with straps and flap covers, but I do not limit myself to the particular
arrangement of such internal fittings, nor to the number of folds in same, as the casos
may be fitted up according to the requirements of the user.
Having now particularly described and ascertained the nature of my said invention
and in what manner the saine is to be performed I declare that what I claim is :
In cases for containing surgical instruments and other like articles, forming the
frames of same with tongue c and groove b, whereby the cases, when closed, are
practically impervious to water and damp, all substantially as herein described with
reference to the accompanying drawings.
