Abstract
A cradle hearth oven for the heat treatment of parts, inside which is arred an inclined rocking trough serving as a parts conveyor. The rocking trough is directly supported on the oven floor and the entire oven is tiltable to adjust the trough inclination.
Claims12
In an oven for the heat treatment of parts inside an oven chamber, a parts conveying device comprising in combination:
- an elongated trough extending longitudinally through the oven chamber at a slight incline, the trough thus having an elevated loading end and a lowered discharge end;
- bearing means for rotatably supporting the trough in such a way that it can execute a rocking motion about a central longitudinal rocking axis;
- drive means for imparting to the trough a reciprocating rocking motion, thereby alternately moving the trough from a median orientation, in which the trough is in approximate balance with respect to its rocking axis, to either side thereof;
- means for supplying treatable parts to the loading end of the trough from above the latter;
- means for discharging the treated parts at the discharge end of the trough;
- and
- a pair of laterally pivotable baffle panels arranged in the area of the loading end of the trough on either side thereof, the panels having a longitudinal pivot axis on their upper ends and engaging alternatingly that lateral extremity of the trough which is lowered in the rocking motion.

- bearing means for rotatably supporting the trough in such a way that it can execute a rocking motion about a central longitudinal axis;
- drive means for imparting to the trough said rocking motion, thereby rocking it from side to side;
- means for supplying treatable parts to the loading end of the trough from above the latter;
- and
- means for discharging the treated parts at the discharge end of the trough;
- and wherein
- the cross-sectional outline of the interior trough wall is substantially elliptical, as approximated by pairs of large and small radii, one large radius defining the trough bottom outline, and the two small radii defining the outlines of laterally spaced, upstanding and inwardly overhanging trough sides.
