摘要： A rotary retort furnace wherein the retort is supported for rotation at only one end outside of the heated furnace shell such that the retort is cantilevered into the shell. The rotary retort has a charging door mechanism that cooperates with a skip hoist loading mechanism to provide charges of the parts to be heat treated that are of a uniform size and are introduced into the retort so as to minimize the loss of any controlled atmosphere. The skip hoist loading mechanism has a vibrating feed hopper that dispenses a weight controlled charge into a skip hoist bucket which, after receiving the predetermined charge of parts, is held in a ready position until such time as a cam mechanism controlling the opening and closing of a door on the charge end of the retort causes the door to open and the skip bucket to be moved to a position wherein the parts are dumped into the retort for heat treating. The internal auger flight for the retort is made by forming a number of toroids from a resilient material, radially cutting each of the toroids and deforming them to form individual flights, and connecting one of the split edges resulting from the cutting to the opposite edge of an adjacent flight such that an axially compressed helical subassembly is obtained. The helical subassembly is then screwed onto a shaft having a number of guide pins axially on the shaft at predetermined spacings thereby both axially extending and radially compressing the helical subassembly. The shaft and the helical subassembly are inserted into a retort shell and one free end of the subassembly is welded to one end of the retort. The shaft is then unscrewed from the subassembly while at the same time being forced axially into the retort such that the edges of the helical subassembly fit tightly against the inside of the retort. After the shaft has been removed, the remaining end of the helical subassembly is welded to the end of the retort.

摘要： A liquid quenching system for use with continuous furnaces for heat treating small parts wherein the quenchant is used to both quench and convey the parts. A supply conduit connects a quench liquid reservoir to a connector between the furnace and a quench chute providing an initial quantity of quench liquid in the quench chute. A feed conduit pumps additional quench liquid into the chute to convey the parts while they are being quenched to a segregating device comprising an inclined, rotating drum having an internal auger flight. The drum permits the return of clean quench liquid to the reservoir and moves the quenched parts substantially dry of quench fluid to a suitable receptacle or further conveying means. A portion of the quench chute forms a trunnion for rotatable support of the receiving end of the drum, the discharge end having a shaft mounted for rotation on the reservoir.
