The screen of a sifter belonging to flour merchants is tamei. But [that] of householders is tahor. R’ Yehudah says: Also, [the screen] of a hairdresser is [susceptible to the] tumah of the seat, because the girls sit in it and have their hair braided.

All hanging loops are tamei, except the loop of a householder’s sifter and sieve; these are the words of R’ Meir. But the Sages say: They are all tahor except the loop of a flour merchant’s sifter, the loop of the sieve of the threshing floors, the loop of a hand sickle, and the loop of a tax collector’s staff; because they assist when [the utensil] is in use. This is the general rule: [Those] designed to assist when [the utensil] is in use are tamei. [Those] designed [merely] for hanging are tahor.

The shovel of bean grinders is tamei. But [the shovel] used in storehouses is tahor. [The shovel] of a wine press is tamei. But [that] of the threshing floor is tahor. This is the general rule: [Utensils that are] designed to hold [something] are tamei, [but those designed] for gathering are tahor.

Musical lyres are tamei. But the lyres of the Levites are tahor. All liquids are tamei. But the liquids of the butchering place are tahor. All scrolls contaminate the hands, except the scroll of the Temple courtyard. A theater horse is tahor. [As for] a sitar, a niktamon, and a tambourine, these are tamei. R’ Yehudah says: A tambourine is [susceptible to the] tumah of the seat, because the woman-wailer sits on it. A weasel trap is tamei. But a mousetrap is tahor.
