Abstract
Abstract A theft-proof tether of substantial length is provided for vehicles such as motorcycles or other movable objects. The tether desirably comprises a spool permanently affixed to the protected object, a chain inseparably connected at one end to, and normally wound on, the spool, a padlock secured on the free end of the chain, and a cover cooperative with the spool to form a weatherprotective housing for the wound-on chain and the chain connected padlock. The protected object may be tethered to a fixed anchorage located almost as far from the object as the full length of the chain.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A theft-proof tether device comprising, in combination, a. a base plate together with means for securely and inseparably anchoring the base plate to a fixed anchorage or to an object to be tethered, b. an outstanding shaft rigidly secured to the base plate, c. a tether chain connected at one end to the shaft and adapted to be wound around the shaft for storage, d. a second plate fixed on the shaft at a substantial distance outward from the base plate for bounding the space in which the chain may be wound around the shaft, the second plate being spaced inward a substantial distance from the end of the shaft, e. a lock carried by the end of the chain remote from the shaft-connected end and adapted to be interlocked also with any selected link of the chain, f. a weather-protective housing cover adapted to fit snugly against the base plate for protecting the chain, lock, shaft, etc. against the weather, and g. means for removably securing the cover in fixed position to the free end of the shaft.
Claim 2
Dependent Claim
179 words
A theft-proof tether device comprising, in combination, a. a base plate together with means for securely and inseparably anchoring the base plate to a fixed anchorage or to an object to be tethered, b. an outstanding shaft rigidly secured to the base plate, c. a tether chain connected at one end to the shaft and adapted to be wound around the shaft for storage, d. a second plate fixed on the shaft at a substantial distance outward from the base plate for bounding the space in which the chain may be wound around the shaft, the second plate being spaced inward a substantial distance from the end of the shaft, e. a lock carried by the end of the chain remote from the shaft-connected end and adapted to be interlocked also with any selected link of the chain, f. a weather-protective housing cover adapted to fit snugly against the base plate for protecting the chain, lock, shaft, etc. against the weather, and g. means for removably securing the cover in fixed position to the free end of the shaft.
Claim 3
Dependent Claim
57 words
A theft-proof tether device as set forth in claim 1 in which a reinforcing plate and an anchoring strap are secured to the inner side of the base plate by headed, anchoring Allen screws whose shanks are passed inward through the base plate and the anchoring plate and whose head cavities are plugged by a hard-setting material.
Claim 4
Dependent Claim
59 words
A theft-proof tether device as set forth in claim 1 in which the base plate is formed marginally with a slot in which a link of the extended chain may be lodged, within the peripheral bounds of the cover, whereby the cover may be secured in its normal position when the chain is unwrapped and extended for tethering purposes.
Claim 5
Dependent Claim
89 words
A theft-proof tether device as set forth in claim 1 in which the shaft extends far enough beyond the second plate to provide a space between the second plate and the cover in which the padlock may be lodged, and in which the second plate is formed with a marginal slot in which an outer link of the chain may be passed in non-interfering relation to the cover, so that the padlock may be housed in an outer chamber defined outside the outer plate and within the applied cover.
Claim 6
Dependent Claim
120 words
A theft-proof tether device as set forth in claim 4 in which a case-hardened sleeve surrounds the shaft with freedom for rotation relative to the shaft, and extends substantIally from the base plate to the outer plate, said sleeve having its inner end cut away adjacent the base plate to such an extent that the cut-away portion and the shaft may be received in the innermost link of the chain, the construction and arrangement being such that the wound-on chain may be rotated with the sleeve into position to enable the outermost chain link to be lodged in the slot of the outer plate, for locating the lock at the outer side of the outer plate but within the cover.
Claim 7
Dependent Claim
21 words
A theft-proof tether device as set forth in claim 1 in which the chain links are all composed of case-hardened steel.
