Electric motor construction

Claim 2

In an electric motor, the combination comprising a shell, end members closing the ends of said shell, a stator mounted in said shell, and a rotor rotatably mounted in said end members, said shell having a plurality of circumferentially spaced axially extending slots therein adjacent each end member, lugs associated with at least some of said openings, each said lug having an opening therein aligned with a slot in said shell, an elongated fastener having an enlarged elongated head and a shoulder adjacent said head such that the fastener can be inserted by axially aligning said head with a slot, moving said fastener radially inwardly through said slot, thereafter rotating said fastener to cause said shoulder to engage the sides of said slot in said shell, said fastener having a portion thereof extending through the opening in said lug, and means engaging said fastener to hold said fastener and said lug in position.

Claim 3

The combination set forth in claim 1 wherein said opening in said lug is elongated.

Claim 4

The combination set forth in claim 2 wherein said lug is L-shaped including a base engaging said shell and having said opening of said lug therein and a leg extending radially outwardly.

Claim 5

The combination set forth in claim 3 wherein said base is transversely curved to correspond with the curvature of said shell.

Claim 6

The combination set forth in claim 4 including indicia extending axially along the opening in said base.

Claim 7

The combination set forth in claim 5 wherein said fastener has a square shank forming said shoulders.

Claim 8

In an electric motor, the combination comprising A shell, end members closing the ends of said shell, a stator mounted in said shell, and a rotor rotatably mounted in said end members, said shell having a plurality of circumferentially spaced axially extending slots therein, lugs associated with at least some of said slots, each said lug having an opening therein aligned with a slot in said shell, an elongated fastener having an enlarged elongated head and a shoulder adjacent said head such that the fastener can be inserted by axially aligning said head with a slot moving said fastener radially inwardly though said slot, thereafter rotating said fastener to cause said shoulder to engage the sides of said slot in said shell, said fastener having a portion thereof extending through the opening in said lug, and means engaging said fastener to hold said fastener and said lug in position.

Claim 9

In an electric motor, the combination comprising A shell, end members closing the ends of said shell, a stator mounted in said shell, and a rotor rotatably mounted in said end members, said shell having a plurality of circumferentially spaced axially extending slots therein, lugs associated with at least some of said slots, each said lug having an opening therein aligned with a slot in said shell, an elongated fastener having an enlarged elongated head and a shoulder adjacent said head such that the fastener can be inserted by axially aligning said head with a slot moving said fastener radially inwardly though said slot, thereafter rotating said fastener to cause said shoulder to engage the sides of said slot in said shell, said fastener having a portion thereof extending through the opening in said lug, and means engaging said fastener to hold said fastener and said lug in position.

Claim 10

The combination set forth in claim 7 wherein said opening in said lug is elongated.

Claim 11

The combination set forth in claim 7 wherein said lug is L-shaped including a base engaging said shell and having said opening of said lug therein and a leg extending radially outwardly.

Claim 12

The combination set forth in claim 9 wherein said base is transversely curved to correspond with the curvature of said shell.

Claim 13

The combination set forth in claim 9 wherein said opening in said base is axially elongated and including indicia extending axially along the opening in said base.

Claim 14

The combination set forth in claim 9 wherein said fastener has a square shank forming said shoulders.

Claim 15

In an electric motor, the combination comprising a shell, end members closing the ends of said shell, a stator mounted in said shell, and a rotor rotatably mounted in said end members, said shell having a plurality of circumferentially spaced axially extending slots therein, a lug associated with at least some of said openings, said lug having an opening therein aligned with an opening in said shell, an elongated fastener having an enlarged elongated head and a shoulder adjacent said head such that the fastener can be inserted by axially aligning said head with a slot, moving said fastener radially inwardly through said slot thereafter rotating said fastener to cause said shoulder to engage the sides of the slot in said shell, said fastener having a portion thereof extending through the opening in said lug, and means engaging said fastener to hold said fastener and said lug in position, said opening in said lug being elongated, said lug being L-shaped including a base engaging said shell and having said opening of said lug therein and a leg extending radially outwardly, said base being transversely curved to correspond with the curvature of said shell, said fastener has a square shank forming said shoulders.

Claim 16

In an electric motor, the combination comprising a shell, end members closing the ends of said shell, a stator mounted in said shell, and a rotor rotatably mounted in said end members, said shell having a plurality of circumferentially spaced axially extending slots therein, a lug associated with at least some of said openings, said lug having an opening therein aligned with an opening in said shell, an elongated fastener having an enlarged elongated head and a shoulder adjacent said head such that the fastener can be inserted by axially aligning said head with a slot, moving said fastener radially inwardly through said slot thereafter rotating said fastener to cause said shoulder to engage the sides of the slot in said shell, said fastener having a portion thereof extending through the opening in said lug, and means engaging said fastener to hold said fastener and said lug in position, said opening in said lug being elongated, said lug being L-shaped including a base engaging said shell and having said opening of said lug therein and a leg extending radially outwardly, said base being transversely curved to correspond with the curvature of said shell, said fastener has a square shank forming said shoulders.

Claim 17

The combination set forth in claim 13 including indicia extending axially along the opening in said base.
