Abstract
Abstract Cylinders or other suitably shaped rollers are provided in the direct vicinity of the key hole portion of the lock, for shifting axially and transversely of the lock along suitable wall portions of the lock. Operation of the key causes internal shifting of the rollers and then moves other lock portions into positions wherein the locking latch first becomes ready to lock and then actually locks. The locking position is fully established by total removal of the key from the lock. This leaves the rollers in a certain position, wherein they in turn hold the lock in shake-proof, locked condition, until the key is reinserted.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
In a lock and anti-theft device mainly for an automobile structure such as the steering wheel, wherein a bolt can be engaged with and disengaged from said structure by different rotations of a drum, under the control of lock core means for shifting the drum into rotatable and non-rotatable positions, and the further control of lock core sleeve means for locking and unlocking the lock core means, the improvement which comprises: a system of rollers disposed between said lock core and core sleeve means and capable of shifting motions both along and across the axis of said means but biased toward motions converging on said axis, while capable of motions diverging from said axis with the help of a key for the lock; and a system of bearing surface means for said rollers, on said lock core and core sleeve means, cooperable with said rollers so that upon and only upon certain of said motions followed by key removal, said core sleeve, rollers and lock core hold said drum in readiness to rotate so as to engage the bolt with the structure.
Claim 2
Dependent Claim
182 words

Claim 3
Dependent Claim
35 words
Apparatus according to claim 1, wherein one of the elements including the lock core means, core sleeve means and drum in one position thereof interferes with motion of the bolt into engagement with said structure.
Claim 4
Dependent Claim
15 words
Apparatus according to claim 2, wherein said drum is the element which interferes as described.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 1, wherein the lock has recess areas adapted to receive and guide said rollers and said shifting motions thereof, with tolerances only allowing slidable insertion of the key between the rollers.
Claim 6
Dependent Claim
47 words
Apparatus according to claim 4, wherein said recess portion has surfaces oblique to the lock axis to guide the rollers, and has surfaces transverse to said axis to provide said holding of the drum in readiness to rotate so as to engage the bolt with said structure.
Claim 7
Dependent Claim
29 words
Apparatus according to claim 1, wherein said lock core means and core sleeve means comprise a two-part structure wherein the core is rotatable and axially shiftable in the sleeve.
Claim 8
Dependent Claim
51 words
Apparatus according to claim 1 having a lock housing which surrounds the lock core means, core sleeve means and drum, the drum and housing structures having, respectively, lock means and recess means, engageable with one another to prevent rotation of the lock core means in a predetermined position of the rollers.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 7, wherein said structures adjacent said lugs and recesses have abutment surfaces adapted for mutual sliding motion.
Claim 10
Dependent Claim
15 words
Apparatus according to claim 1, wherein the system of rollers comprises a pair of cylinders.
Claim 11
Dependent Claim
15 words
Apparatus according to claim 9, wherein eacH of said cylinders has spherically shaped end portions.
Claim 12
Dependent Claim
31 words
Apparatus according to claim 10, wherein each of said end portions is a spherical surface not wider than the cylinder but having a radius longer than the radius of the cylinder.
