Abstract
Abstract A heat transmitting device for conducting heat into the interior of a roast or other body of food to aid in the rapid and more uniform cooking thereof, is provided with a probe for insertion into the food and has heat absorbing fins or elements connected thereto for transmitting heat to the probe to raise its temperature up to or approaching the temperature of an oven or other space in which food being cooked is located. A temperature responsive device located within the heat transmitting probe is connected to a thermometer or other indicating device to indicate the temperature of the food adjacent to the probe whereby it is possible to determine whether the food is being uniformly and satisfactorily cooked.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
A heat transmitting device for use in cooking foods comprising a probe having a tubular body made of material of high heat conductivity, said body being closed at one end into the form of a point for insertion into the food to be cooked, radially extending heat conducting elements of high heat conductivity spaced from the point of the probe and connected to the tubular body to conduct heat to said body for promoting the cooking of the food into which the probe is inserted, a thermometer connected to said probe and located adjacent the end thereof remote from the point of the probe, a stem attached at one end thereof to the thermometer and extending into said tubular body, said stem being of smaller diameter than said tubular body and spaced therefrom throughout the length thereof, a head secured to said stem adjacent the opposite end thereof and positioned within said tubular body near the point of the probe, said head having a threaded engagement with the tubular body adjacent the point of the probe and being in direct heat conducting contact therewith, and sensing means for actuating the thermometer carried by said head.
Claim 2
Dependent Claim
195 words
A heat transmitting device for use in cooking foods comprising a probe having a tubular body made of material of high heat conductivity, said body being closed at one end into the form of a point for insertion into the food to be cooked, radially extending heat conducting elements of high heat conductivity spaced from the point of the probe and connected to the tubular body to conduct heat to said body for promoting the cooking of the food into which the probe is inserted, a thermometer connected to said probe and located adjacent the end thereof remote from the point of the probe, a stem attached at one end thereof to the thermometer and extending into said tubular body, said stem being of smaller diameter than said tubular body and spaced therefrom throughout the length thereof, a head secured to said stem adjacent the opposite end thereof and positioned within said tubular body near the point of the probe, said head having a threaded engagement with the tubular body adjacent the point of the probe and being in direct heat conducting contact therewith, and sensing means for actuating the thermometer carried by said head.
Claim 3
Dependent Claim
87 words
A heat transmitting device as defined in claim 1, wherein the end of the tubular body opposite to that on which the point is formed, is provided with sealing means, and said thermometer has means thereon engaging said sealing means and serving to hold the sealing means in engagement with the tubular body, said thermometer, stem and head being fixedly connected together and dimensioned so that upon threading of the head into the tubular body, the thermometer will be urged into sealing contact with said sealing means.
