Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
239 words
An electric socket wrench which comprises: (A) a housing having a tubular head and a tubular neck; (B) power means provided in the housing; (C) A power driven shaft extending from the power means through the tubular neck into the tubular head; (D) Transmission means for rotating a plurality of driving shafts mounted within the tubular head on said power driven shaft, whereby said driving shafts extend from said housing at right angles to each other in combination with additional means mounted on said housing coacting with the first said means to lock the said shafts from rotation, wherein the transmission means comprises: (A) A first bevel gear affixed to the power driven shaft within the head; (B) A second bevel gear rotatably mounted on one side of said head that meshes with said first bevel gear; (C) One of said driving shafts affixed to the second bevel gear and connected to a socket driving member, wherein said additional means comprises: (A) A free rolling third bevel gear mounted on the power driven shaft spaced inwardly of said first bevel gear meshing with said second gear so that the third bevel gear will rotate in an opposite direction of the first bevel gear; (B) A turn knob threadably mounted on said head having a fourth bevel gear connected to the turn knob that meshes and locks with both said first bevel gear and said free rolling third bevel gear.
Claim 2
Dependent Claim
239 words
An electric socket wrench which comprises: (A) a housing having a tubular head and a tubular neck; (B) power means provided in the housing; (C) A power driven shaft extending from the power means through the tubular neck into the tubular head; (D) Transmission means for rotating a plurality of driving shafts mounted within the tubular head on said power driven shaft, whereby said driving shafts extend from said housing at right angles to each other in combination with additional means mounted on said housing coacting with the first said means to lock the said shafts from rotation, wherein the transmission means comprises: (A) A first bevel gear affixed to the power driven shaft within the head; (B) A second bevel gear rotatably mounted on one side of said head that meshes with said first bevel gear; (C) One of said driving shafts affixed to the second bevel gear and connected to a socket driving member, wherein said additional means comprises: (A) A free rolling third bevel gear mounted on the power driven shaft spaced inwardly of said first bevel gear meshing with said second gear so that the third bevel gear will rotate in an opposite direction of the first bevel gear; (B) A turn knob threadably mounted on said head having a fourth bevel gear connected to the turn knob that meshes and locks with both said first bevel gear and said free rolling third bevel gear.
Claim 3
Dependent Claim
133 words
An electric socket wrench as recited in claim 1, wherein the locking means further comprises: (A) a hub having a plurality of apertures around its circumference mounted midway on the power driven shaft within the tubular neck; (B) A solenoid mounted on the tubular neck so that when the solenoid is activated it can engage one of the apertures on the hub whereby the power driven shaft will not rotate; (C) A switch placed adjacent to the on-off switch and electrically connected to the solenoid; and (D) A stop affixed to the switch so that when the switch is closed the stop will engage the on-off switch keeping the on-off switch in an open position whereby the wrench can be locked electrically and mechanically at the same time preventing damage to the motor.
Claim 4
Dependent Claim
28 words
An electric wrench as recited in claim 2, that further comprises a socket attached to the first bevel gear so that a flexible shaft can be connected thereto.
