Abstract
Abstract The invention is a friction lock which operates upon a throttle hand grip mounted on the steering arm of an outboard motor. An end cap threaded axially with respect to the steering arm urges the hand grip against the shoulder on the steering arm, thereby creating friction to hold the throttle grip in a selected position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
Throttle control mechanism for an outboard motor comprising a throttle control hand grip rotatingly mounted upon a steering arm of an outboard motor, and means for retaining said hand grip in a preselected position comprising means for creating frictional force between the hand grip and the steering arm in opposition to rotation of said hand grip, including means for adjusting said frictional force creating means whereby the frictional force opposing rotation of said hand grip can be varied.
Claim 2
Dependent Claim
78 words
Throttle control mechanism for an outboard motor comprising a throttle control hand grip rotatingly mounted upon a steering arm of an outboard motor, and means for retaining said hand grip in a preselected position comprising means for creating frictional force between the hand grip and the steering arm in opposition to rotation of said hand grip, including means for adjusting said frictional force creating means whereby the frictional force opposing rotation of said hand grip can be varied.
Claim 3
Dependent Claim
54 words
The device of claim 1 wherein said frictional force creating means comprises a first movable abutting means; means for urging said first abutting means against one end of said handle grip; and second abutting means for engaging the other end of said hand grip in opposition to the movement of said first abutting means.
Claim 4
Dependent Claim
60 words
The device of claim 2 wherein said first abutting means comprises an end cap for said hand grip; said means for urging said first abutting means against one end of said hand grip comprises means for threading said cap axially with respect to the steering handle, and said second abutting means comprises a stationary shoulder affixed to the steering handle.
Claim 5
Dependent Claim
90 words
The device of claim 3 wherein said means for threading said cap axially with respect to said steering handle comprises a throttle control rod extending through a bore in the steering handle; means attached to said rod to prevent axial movement thereof in the direction of the outer extremity of said hand grip; and threads upon the opposite end of said rod upon which said end cap is adjustably engaged, said hand grip being keyed to said control rod so that said grip and said end cap move in unison.
Claim 6
Dependent Claim
101 words
A throttle friction locking device for an outboard motor having a twisting hand grip throttle control located upon its steering arm, comprising a throttle control hand grip member mounted for free rotation upon the steering arm of the outboard motor; an annular shoulder extending radially of the steering arm adjacent the inner end of said grip member; and means operative upon the outer end of said grip member for urging saiD grip member and its inner end against said annular shoulder whereby a force of friction is created opposing twisting motion of the hand grip member and its associated throttle control.
Claim 7
Dependent Claim
101 words
A throttle friction locking device for an outboard motor having a twisting hand grip throttle control located upon its steering arm, comprising a throttle control hand grip member mounted for free rotation upon the steering arm of the outboard motor; an annular shoulder extending radially of the steering arm adjacent the inner end of said grip member; and means operative upon the outer end of said grip member for urging saiD grip member and its inner end against said annular shoulder whereby a force of friction is created opposing twisting motion of the hand grip member and its associated throttle control.
Claim 8
Dependent Claim
100 words
The device of claim 5 wherein said means for urging said grip member against said annular shoulder comprises a first threaded member affixed to said steering arm and extending axially thereto; and a second member having threads adapted to rotationally advance and retard axially with respect to said first member; said second member configured to engage the outer end of said hand grip member; and at least one of said members having threads made of a resiliently deformable material so that a resilient bias is imparted to said hand grip member when said second member is threaded into engagement therewith.
