'I'he spoon ofmy invention'can be’of any size

tion of the Way in which the spoon is made.
In all of the examples illustrated the bulb is
in the bowl of the spoon, the bulb l 2 in Figures 1
and 2 being adjacent the junction between the 55

stem and the bowl whereas the bulb 2 I in the flat
ware modiñcation shown in Figure 3 is in the cen
ter of the bowl and the bulb 22 of the thermome
ter in the similar modification shown in Figure 4
is at the extreme tip 23 of the spoon, this latter
form being particularly advantageous in cases
where the depth of the larger quantity of liquid
to be measured for temperature is relatively shal
low as, for example, when the depth‘oi.' the liquid
is only about half ofthe length o1' the bowl of
the spoon.

What _I claim is:
1. A, combined thermometer and spoon, the
bulb of the thermometer being in, and integral
with the' bowl of the spoon and the capillary tube
of the thermometer extending in, and integral
with the stem of the spoon.
2. A combined spoon and thermometer, com
prising a transparent body including integral
handle stem and bowl portions, the bowl portion
of said body being hollowed to provide a bulb for
reception of a thermal expansive fluid and the
handle stem portion being provided with a bore
communicating with said bulb, calibrations pro 10
vided on said handle stem portion along said bore,
and a thermal expansive ñuid filling said bulb and
extending in said bore.
