A pocket wheel furnace having a furnace housing provided with a heat source in the side walls to project heat upon the components requiring heat treatment. The components are loaded into the pockets on the wheel at a first station and travel through the projected heat for the time needed to reach the heat treatment temperature before reaching a discharge station where the components are moved to a quench station. The travel time in the furnace is predetermined and is substantially equivalent for all components in a batch thereof.

An apparatus for heat treating components moving between a starting heat treating position and a discharge heat treating completion position, the apparatus comprising: (a) a heat treating chamber having heating elements therein; (b) a component carrying wheel in said chamber rotatable about a horizontal axis and being formed with pockets arranged around the wheel periphery, each of said pockets having a component receiving surface and an opposite component supportive face spaced from said receiving surface, said surfaces and faces being radially directed to define component receiving openings radially directed outwardly from the periphery of said wheel; (c) means forming a component loading opening in said chamber at the heat treating starting position; (d) means forming a component discharge opening in said chamber angularly displaced from said first means at the position of the completion of the component heat treatment; (e) first means adjacent said chamber component loading opening for feeding the components into said radially directed open pockets on said receiving surface in said carrying wheel while in a first position of orientation; (f) second means adjacent said chamber component discharge opening for receiving components at the completion of the heat treatment thereof while in a position of orientation supported on said opposite face to be reversed from said first position of orientation; and (g) a control system associated with the rotatable component carrying wheel for indexing the pockets one at a time through said first means and regulating the time of components travel from said first means to said second means.
