page_text: I, CECIL URQUHART FISHER, of 1 Castle Street, Holborn, London, in the County
of Middlesex, 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:-
The object of this invention is to prevent the breakage of thermometers, which
is occasionally caused by the dropping of the case containing the thermometer, and to
accomplish this object the case is provided with elastic pads so constructed as to
break the concussion caused by the dropping of the case, as set forth in the following
specification and claim, and illustrated in the accompanying drawing, in which
Fig. 1 is a longitudinal central section of a case containing a thermometer.
Fig. 2 is a section along the line xx fig. 1.
Fig. 3 is a detail view similar to fig. 1 showing a modification.
Similar letters indicate corresponding parts.
In this drawing the letter A indicates a case of suitable material, such as wood,
hard rubber or the like, containing a thermometer B. The ends of the case are
open and each end is provided with an elastic pad having a portion (extending
into the case, a portion D extending beyond the case, and a flange E engaging or
resting on the edge of the case. A convenient substance for the pad is soft rubber.
When the case is dropped end-wise, the portion D, striking the ground will break
the fall of the case and contents, while the portion C, against which the thermometer
abuts will break the fall of the thermometer and the flange E will prevent the pad
from being forced too far into the case.
By making the flanges E of considerable width, the flange will form an elastic
rest for the case A when said case lies or falls lengthwise so that the fall of the
case will be broken by the flanges E when the case falls lengthwise or on its side.

page_text: In the modification shown in fig. 3, the portion C is hollow and has a slide F
pressed by a spring G. When the case falls and strikes on the portion D, the
spring G will yield so as to break the fall of the thermometer B.
The soft rubber flange E also has an advantage in that it grasps the edges of the
pocket in which the case A is carried, thus preventing the liability of the case slipping
out of the pocket when the wearer stoops down.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A case for thermometers provided at each of its ends with an elastic pad having
a portion extending into the case, a portion extending beyond the case, and a flange
engaging the edge of the case, substantially as described.
2. A case for thermometers provided at each of its ends with an elastic pad
having a portion extending into the case, a portion extending beyond the case, and a
flange engaging the edge of the case, said flange being of such width as to form an
elastic rest for the case when the case falls lengthwise, substantially as described.
3. A case for thermometers, provided at each of its ends with an elastic pad having
a portion extending beyond the case, a hollow portion, provided with a slide and
spring, extending into the case, and a flange engaging the edge of the case, sub-
stantially as described.
