Apparatus with an oscillating armature motor

Claim 2

Apparatus including a housing, a tool movable in a guide in the housing, and an electric motor of oscillating armature type mounted in the housing and arranged to drive the tool, the motor having a stator, a carrier fixed to the stator at the pole end thereof, and an oscillating armature lever pivoted on the carrier, the carrier being fixed relatively to the housing by carrier positioning means, and the end of the stator remote from the oscillating armature lever being held to the housing by a clamp connection which permits forced relative movement between the stator and the housing.

Claim 3

Apparatus according to claim 1, in which the carrier is also held to the housing by a second clamp connection.

Claim 4

Apparatus according to claim 1, in which the clamp connection comprises at least one headed-screw cooperating with the housing, which extends with play through a bore in the part which is to be held, and firmly clamps the latter to the housing by means of its head.

Claim 5

Apparatus according to claim 1, in which the positioning means is near the pivot point of the oscillating armature lever on the carrier.

Claim 6

Apparatus according to claim 4, in which the Oscillating armature lever is pivoted on an axle arranged on the carrier, and the positioning means comprises an extension of the axle, which extends with a close fit into a recess in the housing.

Claim 7

Apparatus comprising a housing, an output member mounted to the housing and movable relative thereto, an oscillating armature type electric motor mountable in said housing and engageable to said output member for driving same, the motor including a stator with near and remote parts, a carrier fixed to the near part of the stator, and an oscillating armature pivotal on said carrier via a pivot axis, the armature movement defining a plane generally normal to said axis, the apparatus further comprising first means for positioning the carrier fixedly relative to the housing, and a clamp connection means for securing said remote part of the stator to the housing while permitting forced relative movement of said stator in said plane or in a plane generally parallel thereto relative to the housing.

Claim 8

Apparatus comprising a housing, an output member mounted to the housing and movable relative thereto, an oscillating armature type electric motor mountable in said housing and engageable to said output member for driving same, the motor including a stator with near and remote parts, a carrier fixed to the near part of the stator, and an oscillating armature pivotal on said carrier via a pivot axis, the armature movement defining a plane generally normal to said axis, the apparatus further comprising first means for positioning the carrier fixedly relative to the housing, and a clamp connection means for securing said remote part of the stator to the housing while permitting forced relative movement of said stator in said plane or in a plane generally parallel thereto relative to the housing.

Claim 9

Apparatus according to claim 6 wherein said stator remote part includes a bore therethrough, and said clamp connection means comprises a fastener having a shank part extending through said bore and having a diameter smaller than that of said bore for permitting said forced relative movement of the stator.

Claim 10

Apparatus according to claim 6 further comprising a second clamp connection means for securing said carrier to the housing while permitting relative movement of said carrier in said plane or in a plane generally parallel thereto relative to the housing.
