Rumford wrote two papers [2] [3] detailing his improvements on fireplaces in 1796 and 1798. He was well known and widely read in his lifetime and almost immediately in the 1790s his "Rumford fireplace" became state-of-the-art worldwide. Subsequent testing of Rumford's designs has shown that their efficiency would qualify them as clean-burning ...
Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection. A traditional fireplace can also draw hot air in from the room and expel it through the chimney, further lowering the efficiency. The design of the direct vent ...
A Franklin stove. The Franklin stove is a metal-lined fireplace named after Benjamin Franklin, who invented it in 1742. [1] It had a hollow baffle near the rear (to transfer more heat from the fire to a room's air) and relied on an "inverted siphon" to draw the fire's hot fumes around the baffle. [2]
All models featured metal cabinetry, a service and storage area, and metal ceiling tiles. In the Westchester Deluxe models, the living room and master bedrooms featured built-in wall units. As an added option, customers were presented with the unique Thor-brand combination clothes- and dish-washer , which incorporated the kitchen sink.
Besides its use for domestic heating, in winter people may sleep on top of the stove to keep warm: the large thermal mass (a proper Russian stove weighs about two tonnes) and layered design (in many variants the hot flue is separated from the outer brick shell with a layer of sand or pebbles) ensure that the outer surface of the stove is safe ...
Chimney breast—The part of the chimney which projects into a room to accommodate a fireplace. [21] Crane—Metal arms mounted on pintles, which swing and hold pots above a fire. Damper—A metal door to close a flue when a fireplace is not in use. Flue—The passageway in the chimney. [21] Hearth—The floor of a fireplace.
The primary functions of a fireback are to protect the wall at the back of the fireplace and radiate heat from the fire into the room. The protection was especially important where the wall was constructed of insubstantial material such as daub (a mud and straw mixture coating interwoven wooden wattles), brick or soft stone.
Perhaps because of the complexity of casting a metal model, Hubley's range of marques for the kits was not that wide – basically a 1:20 scale range of Ford Model As and 1932 Chevrolets, a 1:22 scale range of Packards, and two 1:18 scale Duesenbergs. The small range was made up for, though, in the number of variations for each car model.
