Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
274 words
A multiple locking mechanism for a single latching means for a gate, door and the like having one edge hingedly mounted on a jamb member and having a latch bolt extending from its opposite edge toward a second jamb member of a gateway in an enclosure comprising in combination: a. a tubular housing mounted parallel to and on such second jamb member and having a slot formed therein in the zone of swing of the bolt on the gate when the latter is moved between open and closed condition relative to the gateway; b. a rod pivotally mounted in parallel relation to and within said tubular housing; c. a keeper arm mounted on and extending radially from said rod in the plane of swing of the bolt by the gate into and out of the slot in said tubular housing; d. spring means within said tubular housing for urging said keeper arm toward the slot in said housing for striking relation to the bolt when the gate is moved into closed condition and into latched engagement with the bolt when the gate is closed; e. a plurality of lever arms mounted in spaced relation along the length of said rod and extending radially therefrom within said tubular housing; and f. a plurality of lockable slide bars mounted for sliding movement across said tubular housing and each independently engaging a respective one of said lever arms for swinging the latter, the rod and said keeper arm against the action of said spring means upon manual operation of such slide bar to thereby release the bolt on the gate from latched engagement with said keeper arm.
Claim 2
Dependent Claim
274 words
A multiple locking mechanism for a single latching means for a gate, door and the like having one edge hingedly mounted on a jamb member and having a latch bolt extending from its opposite edge toward a second jamb member of a gateway in an enclosure comprising in combination: a. a tubular housing mounted parallel to and on such second jamb member and having a slot formed therein in the zone of swing of the bolt on the gate when the latter is moved between open and closed condition relative to the gateway; b. a rod pivotally mounted in parallel relation to and within said tubular housing; c. a keeper arm mounted on and extending radially from said rod in the plane of swing of the bolt by the gate into and out of the slot in said tubular housing; d. spring means within said tubular housing for urging said keeper arm toward the slot in said housing for striking relation to the bolt when the gate is moved into closed condition and into latched engagement with the bolt when the gate is closed; e. a plurality of lever arms mounted in spaced relation along the length of said rod and extending radially therefrom within said tubular housing; and f. a plurality of lockable slide bars mounted for sliding movement across said tubular housing and each independently engaging a respective one of said lever arms for swinging the latter, the rod and said keeper arm against the action of said spring means upon manual operation of such slide bar to thereby release the bolt on the gate from latched engagement with said keeper arm.
Claim 3
Dependent Claim
55 words
The multiple locking mechanism in accordance with that of claim 1 including a cover plate secured to the said opposite edge of the gate in the region of the bolt thereon for covering the slot formed in said tubular housing against illegal manipulation of said keeper arm in the latter when the gate is closed.
Claim 4
Dependent Claim
52 words
The multiple locking mechanism as in claim 2 in which each of said slide bars has a stop means thereon for engaging the internal wall of the tubular housing and limiting swinging movement of the lever arms, said rod and the keeper arm beyond bolt striking and latching relation to the bolt.
Claim 5
Dependent Claim
101 words
The multiple locking mechanism as called for in claim 3 in which each of said slide bars have a head portion extending from said tubular housing and between the latter and the opposite edge of the gate and the combination therewith of: a. a leg portion on said head portion provided with a bore; and b. an arm portion secured to and extending from said tubular housing adjacent said leg portion and having a bore registerable with the bore in said leg portion for receiving the bow of a padlock for locking said slide bar against movement across said tubular housing.
Claim 6
Dependent Claim
64 words
The multiple locking mechanism in accordance with that of claim 4 in which each of said slide bars is urged toward the gate by action of the respective lever arm, rod and spring means for registering the bore in the leg portions of said slide bar with the bore in the arm portion associated therewith for the receipt of the bow of a padlock.
Claim 7
Dependent Claim
66 words
The multiple locking mechanism in accordance with that of claim 5 in which the leg portion of each slide bar serves to engage the tubular housing upon manual operation of said slide bar to thereby limit sliding movement of the latter and swinging movement of the related lever arm, the rod and said keeper arm just beyond non-striking relation relative to the bolt on the gate.
Claim 8
Dependent Claim
53 words
The multiple locking mechanism in accordance with that of claim 6 including a cross strap insertable through the registered bores in said leg portion and arm portion, and a bore adjacent each end of said cross strap for receiving the bow of padlocks on each side of said leg portion and arm portion.
Claim 9
Dependent Claim
70 words
The multiple locking mechanism in accordance with that of claim 7 in which the cover plate secured to said opposite edge of the gate is an F shape having a head portion secured to such edge of the gate and a leg portion extending therefrom for flat engagement against the open side of said tubular housing in the region of the slot formed therein to overly and cover the slot.
Claim 10
Dependent Claim
52 words
The multiple locking mechanism in accordance with that of claim 8 in which said F shaped cover has a mid-bar extending from the leg portion of said cover to support the bolt on the gate and overly and cover the slot in said tubular housing on that side thereof facing the gate.
Claim 11
Dependent Claim
57 words
The multiple locking mechanism in accordance with that of claim 9 including a U shaped guard having its legs disposed to receive and embrace the mid-bar of said F shaped cover and secured to the gate side of said tubular housing to receive the mid-bar between the latter and the bight portion of said U shaped guard.
