Stanley Matthews Thatcher Heating Company v. Burtis…

But the improvement in the fire-place heater was the result merely of the single change produced by the introduction of the fuel magazine, but one element in the combination. The new and improved result in the utility of a fire-place heater cannot be said to be due to anything in the combination of the elements which compose it, in any other sense than that it arises from bringing together old and well-known separate elements, which, when thus brought together, operate separately, each in its own old way.

Stanley Matthews Thatcher Heating Company v. Burtis…

It has been the practice to so construct base-burning fire-place stoves or heaters that the fuel had to be introduced into the feeder or magazine through a doorway in front; hence the magazine was of a very limited capacity. By so arranging the feed-hole, however, that the fuel can be introduced into the magazine from above, the capacity of the magazine is increased,-a result which I especially aimed at in adopting the first part of my invention, namely, the above-mentioned combination, and in the production of my topfeeding, base-burning fire-place stove.

The fuel magazine holds the fuel in readiness to supply the fire which is to heat both back and front alike with steadiness and uniformity, the magazine being fed through a hole in the outer casing directly, thus obviating the opening of any doors into the combustion chamber when the fire is to be fed, and the consequent cooling off of the heater by admitting fresh air into the device above the grate.
