Complete Specification Left, 17th Jan., 1889
Complete Specification Accepted, 23rd Feb., 1889
I, JAMES ARNOLD, of the firm of Arnold and Sons, of West Smithfield in the
City of London, Surgical Instrument Makers do hereby declaro the nature of this
invention to be as follows:-
The object of my invention is to provide simple and effective means for protecting
or guarding clinical and other thermometers from being easily broken, and the
invention refers to the employment for such purpose of a spring clip or shield
which, while guarding the thermometer to which it is applied from being easily
broken, at the same time allows the scale on the same to be seen equally well, or
even better than when the guard or protector not employed.
According to my invention I provide a clip or shield which may be made of
metal, vulcanite, celluloid, or of other suitable material or materials or combination
of same, and in one or more pieces, bent or curved into tongs-like form, the internal
form being so curved, or made, as to adapt itself to the contour of the sides of
the thermometer to be protected, and in such manner that while clipping it by the
spring-like action of the tongs on the theremometer and protecting same from injury,
the side or sides or that part on which the scale is written, or engraved, is clearly
visible. The ends or points of the tongs should be bent or curved so as to firmly
clip the thermometer neck and when the latter is removed from the guard the
points of the tongs, by the spring action, are caused to meet one another. The form
and size of the guard should be arranged to suit the particular class of instrument to
which it is intended to be applied.
The thermometer can be fitted to and removed from the clip or guard with the
greatest facility.

I, JAMES. 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 provide simple and effective means for protecting 5
or guarding clinical and other thermometers from being easily broken, and the
invention refers to the employment for such purpose of a spring clip or shield which
while guarding the thermometer to which it is applied from being easily broken as
aforesaid, at the same time allows the scale on the same to be seen equally well, or
even better, than when the guard or protector is not employed.

Figure 1 of the accompanying drawings is an elevation of a thermometer shewing
a guard, constructed according to my invention, applied thereto. Figure 2 is a
horizontal section of the same on a larger scale than that shewn at Figure 1, and
taken on the line X Y of the same figure. Figure 3 is a perspective view on the
same scale to that of Figure 2, of the guard separately. Figures 4 and 5 shew in 1
front and back elevation respectively, a thermometer with guard applied, of slightly
modified form; Figure 6 being a horizontal section on line X1 Y' of Figure 5.
Similar letters of reference refer to like parts in all the figures.
According to my invention I provide a clip or shield A which may be made of
metal, vulcanite, celluloid, or of other suitable material or materials or combination of
same, and in one or more pieces, bent or curved into tongs like form as shewn, the
internal form being so curved or made as to adapt itself to the contour or shape of
the sides of the thermometer B to be protected, and in such manner that while
clipping the thermometer B by the spring-like action of the tongs A on the
thermometer B and protecting same from injury, the sides Figures 1 to 3, or side
Figures 4 to 6, or that part on which the scale is written or engraved is clearly
visible. The ends or points of the tongs should be bent or curved so as to firmly
clip the thermometer neck and when the latter is removed from the guard the points
of the tongs by the spring action may be caused to meet one another. The form
and size of the guard should be arranged to suit the particular class of instrument to
which it is intended to be applied.
The thermometer B can be fitted to, and removed from, the clip or guard A with
the greatest facility.

page_text: 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 1
claim is :-
The spring clip shield, protector or guard A for partially surrounding a thermometer
and thus guarding same from liability to accident substantially as set forth.
Dated this 17th day of January 1889.
