Abstract
Abstract A safety belt buckle construction in which a latching dog and biasing spring are integrally connected in such relation within a casing as to enable an operating means to simultaneously flex the spring and move the the dog into operative latching position. The rigidly and integrally connected biasing means and latching dog provide a mechanical device capable of withstanding large belt forces. The movable mounting construction of the latch is such as to provide added strength to the latching dog.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
242 words
In a safety belt buckle construction the combination of a casing having a base wall, upstanding laterally spaced side walls, a cover for the casing having a top opening therein, said base and side walls and cover defining a chamber, a lever movably mounted on the casing within the chamber comprising a pair of spaced lifting arms which are pivoted intermediate their ends to the side walls, said lifting arms at their ends having a rigidly connected push button plate rearwardly spaced from the pivot axis of the lifting arms and the forward ends of said arms forwardly of said pivot axis each having a longitudinally extending elongated slot therein, a latching member having a front latching dog portion and rigidly attached rearwardly extending spaced spring arms, said spring arms and latching member adjacent their attachment location having lateral projection means lying within the arm slots for free horizontal floating action therein fore and aft and for vertical movement together with the fore ends of the lifting arms, said spring arms having resiliency normally biasing the push button plate toward the opening of the cover for finger depression, the latching dog having a rearwardly and downwardly sloping detent between the lifting arms, said casing at the front having an opening for receiving an opening provided belt tongue, means pivoting the latching dog portion to the casing, the latching dog normally assuming a tongue latching position under biased influence of said spring arms.

Claim 3
Dependent Claim
29 words
The buckle as described in claim 1 in which means is provided on the casing to limit the insertion of a belt tongue into latching relation with said dog.
Claim 4
Dependent Claim
74 words
As an article of manufacture a combination latching dog and biasing spring means formed of sheet metal including a rigid latching dog having a depressed latching dimple portion at its rear end And at each side of said dimple being provided with closely adjacent reinforcing devices for pivoting the latching dog, and elongated flexible and resilient biasing spring arms integrally connected to said latching dog extending rearwardly from the dimple end of the dog.
Claim 5
Dependent Claim
74 words

Claim 6
Dependent Claim
138 words
In a safety belt buckle construction the combination of a casing having a chamber therein, an operating device movably mounted on the casing, a latching dog movably mounted at its front end to the casing for vertical movement at its rear end within the chamber, its rear end having belt tongue latching means thereon, spring means connected at the rear end of the latching dog extending rearwardly of said latching means normally biased to urge said operating device to an upward neutral operating position and normally biased to also urge the rear latching means of said latching dog to a downward belt tongue latching position, said casing having an opening therein to receive a belt tongue therein to be engaged by and held in the chamber by said latching means when the dog is in normal latching position.
Claim 7
Dependent Claim
138 words
In a safety belt buckle construction the combination of a casing having a chamber therein, an operating device movably mounted on the casing, a latching dog movably mounted at its front end to the casing for vertical movement at its rear end within the chamber, its rear end having belt tongue latching means thereon, spring means connected at the rear end of the latching dog extending rearwardly of said latching means normally biased to urge said operating device to an upward neutral operating position and normally biased to also urge the rear latching means of said latching dog to a downward belt tongue latching position, said casing having an opening therein to receive a belt tongue therein to be engaged by and held in the chamber by said latching means when the dog is in normal latching position.
Claim 8
Dependent Claim
52 words
The safety belt buckle construction as defined in claim 4 in which the spring means comprises a plurality of spaced leaf type flexible spring arms extending rearwardly from the latching dog and normally tensioned to urge the operating device to a neutral operative position and the dog to a tongue latching position.
Claim 9
Dependent Claim
167 words
In a safety belt buckle construction the combination of a casing having a chamber therein and a belt tongue opening to the chamber, a latching dog pivoted at its forward end upon the casing adjacent to said opening for vertical movement at its rear end in the casing, the rear end of the dog having a latching means for engaging a belt tongue, said latching dog forwardly beyond said latching means having rearwardly extending leaf type spring arm means, a push button member movably mounted upon said casing having a finger engaging member disposed rearwardly of the mounting thereof and forwardly of the said mounting having means for pivotally raising the rear end of the dog against further tensioning of said spring arm means to move the latching means to a tongue releasing position, the spring arm means being under tension at all times to position said push button finger engaging member to an inactive position and also normally urging said dog into a tongue latching position.
Claim 10
Dependent Claim
167 words
In a safety belt buckle construction the combination of a casing having a chamber therein and a belt tongue opening to the chamber, a latching dog pivoted at its forward end upon the casing adjacent to said opening for vertical movement at its rear end in the casing, the rear end of the dog having a latching means for engaging a belt tongue, said latching dog forwardly beyond said latching means having rearwardly extending leaf type spring arm means, a push button member movably mounted upon said casing having a finger engaging member disposed rearwardly of the mounting thereof and forwardly of the said mounting having means for pivotally raising the rear end of the dog against further tensioning of said spring arm means to move the latching means to a tongue releasing position, the spring arm means being under tension at all times to position said push button finger engaging member to an inactive position and also normally urging said dog into a tongue latching position.
