Here are pages 60 and 61 from the vintage booklet The Enterprising Housekeeper from the sixth edition (1906).

Enterprise

Raisin and Grape Seeder

Directions For Operating

After fastening the Seeder to the table, set the rubber roller moderately tight against the toothed cylinder by means of the thumb screw (marked A). Be careful to see that the roller turns freely on its shaft.

Wet the raisins and feed into the hopper, turning the crank at the same time. Remember the hopper must not be filled, but the raisins sprinkled in only so fast as the roller will grasp them, which means only two or three at a time.

If too much pulp comes with the seeds the rubber roller is not tight enough against the cylinder.

The surface of the roller should be kept clean and free from sugar, in order that the seeds may be extracted without wasting the pulp of the raisin.

When the crank sticks or “turns hard” while in use, wash the machine by loosening the thumb screw and holding the Seeder under a stream of hot water. It is an accumulation of sugar from the raisins which causes this sticking, and the hot water dissolves and washes it away.

After using, clean in the same manner; loosen the thumb screw and hold the machine under a stream of hot water and turn the crank backward and forward. Wipe and dry thoroughly before putting away. Too much emphasis cannot be laid upon this point with all household utensils and machinery. After using and cleaning, utensils must be thoroughly dried.

If, after not having used the Seeder for a few days, the crank turns hard or will not turn at all, wash as above, as the trouble is caused by the sugar from the raisins sticking to the working parts.
