Description
Large cast iron automatic salter which sits on 2 double legs made of L-girders with cross bars. Supported under machine by L-girder cross-brace. Entire upper assembly bolted to horizontal girder frame, which in turn bolts to the legs and brackets. Large hopper atop right end of machine (facing ID plate). Compartment under hopper with missing inspection plate bears millmark: two concentric circles with "Seattle Astoria Iron Works. Seattle Wn." between the circles and a monogram of superimposed "A, I, W" in the centre of the smaller circle. A brass identification plate below and beside the millmark reads: "Automatic Salting Machine/ Gheen No. 713425 Nov. 11, 1902/ Patents No. 720128 Feb. 10, 1903/ MCH. No. 348 1918/ Manufactured by the/ Seattle-Astoria Iron Works/ Seattle Wash." This is repeated on the leg assemblies. Within the compartment an endless worm drive on a shaft is driven within via an external bevel gear by a single roller chain which passes around a shaft directly below which is in turn driven by the main chain which is driven by the main drive shaft. Directly in front of and below the hopper compartment is a can chute with protective bar which is on an incline so that the cans roll down to a 6 lobed star wheel, curved to fit the cans. An output chute continues down to the left of the wheel, which is driven via a complex, snowflake shaped gear behind the main reduction gear. The main drive shaft runs perpendicular to the long axis of the stand, to the left of centre. Near the end of it is a clutch shaft, which has a 4-spoked handwheel, followed by a belt-driven flywheel with a grease fitting on its sleeve. Inboard of the flywheel is a clutch plate and a pressure plate, linked by spring-loaded articulating arms to a throwout bearing. The throwout bearing is operated via a large handle on the back of the machine, connected to the bearing by a long shaft. A gear on the throwout bearing sleeve meshes with a large gear to its right and another (on the left and below) which is on the end of the main drive shaft. All these are enclosed in a partial gear-guard. The main drive shaft has 4 cam lobes and a chain sprocket, and controls most of the functions of the machine. At the far end of the shaft is a massive sleeve with wavy channels cut in it which control the intermittent operations of the machine by moving arms which have small wheels to follow the channels. It appears as though some parts oft he machine may be missing, as the means whereby the fish is admitted to the machine prior to being forced into the can is not apparent. There is a scoop in the form of half of a hollow disc is just above an opening to the canning push arm, and it rocks under the influence of a spring-enclosed rod run off an inside channel on the end sleeve. A 3-tined fork passes through the wall of the scoop and into the fish compartment.
