Mishnayos Keilim Perek 5 Mishnah 3

עטרת כירה – round building made on the top of the portable stove on feet with caves for two pots/כירה in order to preserve its heat.

טהורה – but if the portable stone on feet with caves for two pots became impure, the crown did not become impure, for the crown is not considered as attached to the portable stove with caves for two pots.

טירת התנור (the surrounding of an oven/brick-work/fender) – the courtyard of the oven, it is the language of (Genesis 25:16): “[These are the sons of Ishmael and these are their names] by their villages and their encampments: [twelve chieftains of as many tribes].” It is ap lace in front of the oven that is surrounded by partitions where they place in it the bread when they detach/ shovel out bread from [where it sticks to] the oven.

בזמן שהוא גבוהה ארבעה – as the measure of the height of the oven (which is four handbreadths) at its outset.

אפילו על שלש אבנים – that its attachment/connection was not done well but rather, it is lying only on three stones and is glued the oven, it is considered an attachment.

בית הפך (socket/cruse) – a place that is made on the sides of the portable stove on feet with caves for two pots that they place upon it a cruse of oil to make tepid/cool.

בית תבלין – a place where they place in it the spices.

בית הנר – a place where they place in it the lamp.

מיטמאין במגע – if an unclean reptile came in contact within the portable stove on feet with caves for two pots, these places became unclean through the defilement of the portable stove on feet with caves for two pots. And similarly, if one of these places became defiled through contact with the unclean reptile, the portable stove on feet with caves for two pots became impure with them, for they are considered like the portable stove on feet with caves for two pots and they are one thing regarding the matter of defilement through physical contact.

ואין מיטמאין באויר – if an unclean reptile was suspended in the airspace of the portable stove on feet with caves for two pots but did not come in contact with it, even though it is defiled, for an earthenware vessel becomes defiled through airspace, they are [ritually] pure, for they are not attached to it other than through the matter of physical contact. Because from the Torah, they are not attached to it, but the Rabbis decreed upon them defilement, as the Rabbis made an indication/sign not to defile it by airspace, in order that they not burn upon them heave-offering and Holy Things.

ור' שמעון מטהר – [Rabb Shimon declares it pure] even through physical contact. Every place where defilement did not come in contact with it for each and every vessel is separate/independent. And the Halakha is according to Rabbi Meir.
