Abstract
Abstract A drive hub is provided having an inner actuating sleeve operatively connected to and selectively controlled by a manual external actuator and wherein a coupling connection is provided between the actuating sleeve and a cooperating outer clutch gear, so that when the manual actuator is operated in either direction, the actuating sleeve will move axially relative to the clutch gear to apply a preload thereon. The coupling connection includes a pair of spaced tabbed guide washers slidably supported between the actuating sleeve and the clutch gear and a coil spring interposed between the washers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words
In a clutch for effecting a driving connection between a power shaft and a wheel hub, the combination comprising; (1) a first toothed member adapted to be connected to the power shaft; (2) a second toothed member, (a) axially movable into and out of engagement with said first toothed member, and (b) adapted to be drivingly connected to the wheel hub; (3) actuator means for effecting movement of said second toothed member with respect to said first toothed member; (4) coupling means providing a lost motion connection between said actuator means and said second toothed member comprising; (a) a first sleeve means operatively connected to said actuator means for axial movement thereby, (b) second sleeve means carried by said second toothed member, and (c) spring means connected to said first and second sleeve means and acting therebetween whereby said first and second sleeve means are movable with respect to each other to provide a preload on said second toothed member when the teeth of said first and second toothed members are not in alignment and when said first and second toothed members are in engagement but under high torque loads.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
Claim 1 wherein said spring means comprises a single coil spring positioned concentric with said first sleeve means.
Claim 4
Dependent Claim
31 words
Claim 1 wherein said first and second sleeve means and said spring means are positioned concentrically with respect to each other to ensure proper loading and unloading of said spring means.
Claim 5
Dependent Claim
44 words
Claim 3 wherein said connection of said spring means to said first and second sleeve means comprises a pair of spaced guides in engagement with the ends of said spring means and movable with respect to both of said first and second sleeve members.
Claim 6
Dependent Claim
25 words
Claim 4 wherein said first and second sleeve members are provided with axially extending slots and said guides have tabs movable positioned within said slots.
Claim 7
Dependent Claim
29 words
Claim 5 wherein said guides comprise circular washers positioned between said first and second sleeve means and said tabs extend both radially inwardly and outwardly from said circular washers.
Claim 8
Dependent Claim
21 words
Claim 4 wherein abutment means are provided on said first and second sleeve means to limit axial movement of said guides.
Claim 9
Dependent Claim
60 words
Claim 7 wherein one of said abutment means engages said guide means upon rotation of said actuator means in one direction to preload said second toothed member in one direction and wherein the other abutment means engages said guide means upon rotation of said actuator means in the other direction to preload said second toothed member in the other direction.
Claim 10
Dependent Claim
19 words
Claim 8 wherein said operative connection between said actuator means and said first sleeve means comprises a cam means.
Claim 11
Dependent Claim
27 words
Claim 8 wherein said cam means comprises a cam follower carried by said first sleeve means and movable in a cam slot provided in said actuator means.
