Improvements in Cases for Protecting Watches.
I, JOHN BRIERLEY HOWARD of Penny Bank Chambers Halifax in the County
of York, Patent Agent do hereby declare the nature of this invention which has
been communicated to me by Otto Busster of Nuremberg, Bavaria in the Empire
of Germany, 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 a watch protecting case with an elastic plate serving as
an elastic support for the watch giving way under pressure or when knocked. The
case consists of two parts, which are slid one over the other, and of which one part
may be of metal, or of a metal ring with a bottom of any other material forced
therein. The other part of the case is made of transparent celluloid or metal ring,
into which a plate of glass or transparent celluloid is inserted.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings in
which :-
Fig. 1 is a section of the watch protecting case with the watch therein.
Fig. 2 is a side elevation of one part of the case.
Figs. 3 and 6 are side and front elevations of the elastic spring plate.
Fig. 4 is a side elevation of one part of the case made of metal and to be forced
into the part shewn by Fig. 2.
Fig. 5 is another view of the same part of the case which when in position is
forced into the part shewn by Fig. 2 so making a box or hollow case.
As seen by Figs. 4 and 5 elastic arch like noses c are cut or pressed out of the
margin a of what I will call the lower part of the case b, these press against the
margin d, of what I will call the upper part of the case e, they admit at the same
time of an easy sliding of the latter thus preventing the watch moving or shaking
in the case.
The margin d is not in contact with the collar or flange, when a
watch is enclosed in the case so that in case of knocks or pressure the upper part
together with the watch and plate 9 will, on account of the elasticity of springs h,
give way without damaging the watch. Another arrangement is shewn in Fig. 7
in which the upper part or lid is connected with the lower part or case by means
of a hidden joint or hinge. The edge of the case is bent round inwards and has at
the place where the lid is hinged a small recess i (Fig. 8) and small tongues k are
cut out and bent round (Fig. 9) and these serve to hold the bearings p firmly in
position. A bearing p is first introduced into the recess i and over it the second
tongue kis tightly bent, and the small pino (Fig. 10) is held by one loop n of the
lid and is introduced along with the second bearing p into the notch i and over this
the second tongue k is pressed (Fig. 11).
A rim is soldered in the margin of the lid to receive the glass or the celluloid
plate.
Having now particularly described and ascertained the nature of my said
invention I declare that what I claim is :
1. A watch protecting case in the lower part b of which a plate g with elastic
tongues his inserted, whereby the watch together with the lid may in case of
knock or pressure approach the lower part or back of the case without being
damaged.
2. In watch protecting cases as herein described the arrangement of elastic, arch
like noses
c for the purpose herein described and as illustrated by drawings
annexed.

page_text: 3. In watch protecting cases as herein described the arrangement of a lid
revolving on a hinge in which the pin b, being held by a loop of the lid, is
introduced into two bearings which are held by loops cut and formed out of the
flange m of the lower part of the case so that soldering is not necessary and the
hinge is invisible from the outside.
Dated this 21st day of April 1894.

Applicant.
