Abstract
Abstract A lever operated control unit includes two brackets of metal stampings which are adjustably connected together. A lever crank, which is also a metal stamping, is rotatable on a pivot bolt secured to the brackets, and a lever is adjustably mounted on the lever crank. The lever crank is adapted to operate a control member such as a push-pull cable. A rod is pivoted to the lever crank and has stop collars that cooperate with a pivot fitting on one of the brackets to limit the travel of the cable.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
209 words
A lever operated control unit for actuation of the core of a cable having a sheath over the core having a first bracket, a lever crank having a lever connected thereto, said lever crank being mounted for pivotal movement relative to said first bracket, a second bracket, means for mounting the lever rigidly on the crank in any one of a number of selected positions radiating outwardly from the pivot axis of the lever crank to position selectively the lever relative to the cable direction, said lever crank having a portion extending therefrom a greater distance from the pivot axis thereof than the lever mounting means, attaching means mounted on the extending portion of said lever crank remote from the pivot Axis of said lever crank and connected to a cable core which is axially slidable in said sheath, clamping means on said first bracket remote from said attaching means for gripping the sheath of the cable but permitting axial movement of the core therein, and means for mounting said first bracket on said second bracket in any one of a number of selected positions of orientation about said pivot axis whereby to facilitate selection of the relative positioning of the lever crank and the direction of the cable.
Claim 2
Dependent Claim
209 words
A lever operated control unit for actuation of the core of a cable having a sheath over the core having a first bracket, a lever crank having a lever connected thereto, said lever crank being mounted for pivotal movement relative to said first bracket, a second bracket, means for mounting the lever rigidly on the crank in any one of a number of selected positions radiating outwardly from the pivot axis of the lever crank to position selectively the lever relative to the cable direction, said lever crank having a portion extending therefrom a greater distance from the pivot axis thereof than the lever mounting means, attaching means mounted on the extending portion of said lever crank remote from the pivot Axis of said lever crank and connected to a cable core which is axially slidable in said sheath, clamping means on said first bracket remote from said attaching means for gripping the sheath of the cable but permitting axial movement of the core therein, and means for mounting said first bracket on said second bracket in any one of a number of selected positions of orientation about said pivot axis whereby to facilitate selection of the relative positioning of the lever crank and the direction of the cable.
Claim 3
Dependent Claim
37 words
A control unit according to claim 1 in which said lever crank has openings lying substantially on lines radiating from said pivot axis, and fastener means projecting through a plurality of said openings and through said lever.
Claim 4
Dependent Claim
20 words
A control unit according to claim 1 including plastic washers on opposite sides of said lever crank and bearing thereagainst.
Claim 5
Dependent Claim
130 words
A control unit for actuation of the core of a cable having a sheath over a core, said unit comprising bracket means, actuating means movable in opposite directions on said bracket means for push-pull engagement with said core to move the same axially in opposite directions, means on said bracket means for clamping said sheath but permitting axial movement of said core, and stop means remote from said cable for limiting the displacement of said actuating means in each of said opposite directions; said stop means including a member independent of the core and connected to the actuating means for movement therewith, abutment means on the bracket means separate from the sheath clamping means, and spaced stop-forming elements mounted on said independent member and selectively engageable with said abutment means.
Claim 6
Dependent Claim
130 words
A control unit for actuation of the core of a cable having a sheath over a core, said unit comprising bracket means, actuating means movable in opposite directions on said bracket means for push-pull engagement with said core to move the same axially in opposite directions, means on said bracket means for clamping said sheath but permitting axial movement of said core, and stop means remote from said cable for limiting the displacement of said actuating means in each of said opposite directions; said stop means including a member independent of the core and connected to the actuating means for movement therewith, abutment means on the bracket means separate from the sheath clamping means, and spaced stop-forming elements mounted on said independent member and selectively engageable with said abutment means.
Claim 7
Dependent Claim
83 words
A control unit according to claim 4 in which said actuating means comprises a lever crank rotatably mounted on said bracket means, said independent member is a rod pivotally connected to said lever crank offset from the means for engagement with said core, said stop-forming elements are collars adjustably mounted on said rod, and said abutment means is a fitting pivotally mounted on said bracket means and through which said rod projects and with the collars being on opposite sides of said fitting.
Claim 8
Dependent Claim
37 words
A control unit according to claim 5 in which said bracket means comprises first and second brackets, and means securing said brackets together in selected positions of orientation about the axis of rotation of said lever crank.
Claim 9
Dependent Claim
47 words
A control unit according to claim 6 including a lever, and means for attaching said lever in selected positions on said lever crank, said selected positions being such that in each said position the lever extends generally radially of the axis of rotation of said lever crank.
Claim 10
Dependent Claim
16 words
A control unit according to claim 1 in which said brackets are of sheet metal stampings.
Claim 11
Dependent Claim
17 words
A control unit according to claim 1 in which said lever crank is a sheet metal stamping.
