Abstract
Abstract A device for moving an actuating arm comprising a plate upon which the actuating arm is mounted for rotation through a predetermined angle and a threaded shaft also rotatably mounted on such plate. Means are provided for connecting the output shaft of an electric motor to the thread shaft. A slide is mounted parallel to the threaded shaft and a nut is immobilized in rotation by the slide and adapted to move longitudinally of the threaded shaft upon rotation of the threaded shaft. A first lever is secured to the axis of the operating arm and a second lever is pivotally connected at one end to the first lever and at its other end to the nut, whereby movement of the nut due to rotation of the threaded shaft will cause the first lever to rotate the second lever and thus the operating arm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A device for moving an actuating arm comprising a plate upon which the actuating arm is mounted for rotation through a predetermined angle, a threaded shaft also rotatably mounted on the said plate, means for connecting the output shaft of an electric motor to said threaded shaft, a slide mounted parallel to said threaded shaft, a nut immobilized in rotation by said slide and adapted to move longitudinally of said threaded shaft upon rotation of the threaded shaft, a first lever secured to the axis of the operating arm, and a second lever pivotally connected at one end to said first lever and at its other end to said nut, whereby movement of said nut due to rotation of said threaded shaft will cause said first lever to rotate said second lever and thus said operating arm.
Claim 2
Independent Claim
137 words
A device for moving an actuating arm comprising a plate upon which the actuating arm is mounted for rotation through a predetermined angle, a threaded shaft also rotatably mounted on the said plate, means for connecting the output shaft of an electric motor to said threaded shaft, a slide mounted parallel to said threaded shaft, a nut immobilized in rotation by said slide and adapted to move longitudinally of said threaded shaft upon rotation of the threaded shaft, a first lever secured to the axis of the operating arm, and a second lever pivotally connected at one end to said first lever and at its other end to said nut, whereby movement of said nut due to rotation of said threaded shaft will cause said first lever to rotate said second lever and thus said operating arm.
Claim 3
Dependent Claim
62 words
A device as claimed in claim 1 further including at least one adjustable stop having an inclined edge which slides on a slot in the plate, the inclination of the slot being at a predetermined angle with regard to the threaded shaft to permit adjustement of the movement of the nut and thereby of the angle of rotation of the actuating arm.
Claim 4
Dependent Claim
59 words
A device as claimed in claim 1, wherein the electric motor comprises two coupled armatures or rotors with corresponding pairs of polar pieces and brushes placed in a single carcass or stator, said rotors and polar pieces being placed side by side in the same plane so as to increase the power of the motor without increasing its thickness.
Claim 5
Dependent Claim
29 words
A device as claimed in claim 3, wherein the two rotors have blade collectors and are fed by the battery of a vehicle into which the device is mounted.
Claim 6
Dependent Claim
24 words
A device as claimed in claim 3, wherein the mutual coupling of the two rotors is combined with a speed reducer or multiplier device.
Claim 7
Dependent Claim
23 words
A device as claimed in claim 1, wherein the means connecting the output shaft to the threaded shaft comprises a rotary flexible transmission.
Claim 8
Dependent Claim
18 words
A device as claimed in claim 1, wherein the actuating arm is connected to a vehicle window regulator.
