Abstract
Abstract A device for orienting an object on a flat surface includes two levers which are pivotably coupled to the surface at pivot points between the ends of the levers. An actuating device is supported by and coupled between one end of the levers. The other ends of the levers are free to urge the object into the desired orientation and location upon energization of the actuating device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
A device for orienting an object on a flat support surface comprising: first lever means having a first orienting end and a first actuated end, said first lever means being pivotably coupled to said flat support surface at a first pivot point between said first orienting end and said first actuated end; second lever means having a second orienting end and a second actuated end, said second lever means being pivotably coupled to said flat support surface at a second pivot point between said second orienting end and said second actuated end, said first and second pivot points being located to span said object; actuating means supported by and pivotably coupled to said first and second actuated ends, at least one of said lever means being configured to include opposite facing angles to provide clearance between said at least one lever and said actuating means, whereby energization of said actuating means pivots said first and second levers and said first and second orienting ends urge any object on said support surface into a desired orientation and location.
Claim 2
Independent Claim
177 words
A device for orienting an object on a flat support surface comprising: first lever means having a first orienting end and a first actuated end, said first lever means being pivotably coupled to said flat support surface at a first pivot point between said first orienting end and said first actuated end; second lever means having a second orienting end and a second actuated end, said second lever means being pivotably coupled to said flat support surface at a second pivot point between said second orienting end and said second actuated end, said first and second pivot points being located to span said object; actuating means supported by and pivotably coupled to said first and second actuated ends, at least one of said lever means being configured to include opposite facing angles to provide clearance between said at least one lever and said actuating means, whereby energization of said actuating means pivots said first and second levers and said first and second orienting ends urge any object on said support surface into a desired orientation and location.
Claim 3
Dependent Claim
44 words
The device of claim 1 wherein said object is substantially rectangular, and wherein said first and second pivot points are arranged to span a corner of said object whereby said orienting ends urge two sides of said object upon energization of said actuating means.
Claim 4
Dependent Claim
31 words
The device of claim 2 further including first and second rollers rotatable coupled to said first and second orienting ends, respectively, whereby said lever means contact said object through said rollers.
Claim 5
Dependent Claim
42 words
The device of claim 3 wherein said actuating means is a fluid cylinder having a chamber and a slideable shaft, said shaft being coupled to one of said actuated ends and said chamber being coupled to the other of said actuated ends.
Claim 6
Dependent Claim
43 words
The device of claim 4 further including a mounting base, said first and second lever means being pivotably coupled to said mounting base at said first and second pivot points respectively, whereby said device is removable from said support surface as a unit.
Claim 7
Dependent Claim
36 words
The device of claim 1 wherein the distance between said pivot points and said orienting ends exceeds the distance between said pivot points and actuated ends, whereby motion of actuating means is multiplied by said levers.
Claim 8
Dependent Claim
30 words
The device of claim 6 further including first and second rollers rotatably coupled to said first and second orienting ends respectively, whereby said levers contact said object through said rollers.
Claim 9
Dependent Claim
42 words
The device of claim 7 wherein said actuating means is a fluid cylinder having a chamber and a slideable shaft, said shaft being coupled to one of said actuated ends and said chamber being coupled to the other of said actuated ends.
Claim 10
Dependent Claim
43 words
The device of claim 8 further including a mounting base, said first and second lever means being pivotably coupled to said mounting base at said first and second pivot points respectively, whereby said device is removable from said support surface as a unit.
