International Classification:

B25B 712

US Classification:

813835

Abstract:

A wrench comprising an upper jaw member and a lower jaw member, the lower jaw member extending into an upper arm member, the upper jaw member being pivotally connected to the lower jaw member, a biasing spring operatively associated with the upper and lower jaw members for biasing the jaws in an open position, an intermediate arm member pivotally connected to said upper arm member at the rear end portions thereof, the intermediate arm member being provided at the front end portion thereof with an inclined surface which is adapted to slidably engage the rear surface of the upper jaw member, and lower handle member pivotally connected with the intermediate arm member and the upper arm member, whereby when the lower handle member is compressed toward the intermediate arm member, the inclined surface of the front end portion of the intermediate arm member is caused to ride along the rear portion of the upper jaw member, forcing the upper jaw member to close toward the lower jaw member.

International Classification:

B25B 1328

US Classification:

81 99

Abstract:

A wrench comprising a body member having a lower jaw disposed at one end thereof, a head member having a spring engaging surface and a base engaging surface, the head member being pivotally connected to the body member in the vicinity of the lower jaw and defining an upper jaw, a handle member pivotally connected to the body member, biasing spring disposed between the body member and the handle member for biasing the handle member away from the body member, the handle member containing a lever engaging end portion which slidably engages the base engaging surface of the head member for separating the upper jaw of the head member from the lower jaw of the body member through the squeezing of the handle member toward the body member against the bias of the biasing spring, and a retaining spring attached at one end to the body and at the other end of the spring engaging surface of the head member, whereby, when the handle is released, the upper jaw of the head member is caused to close toward the lower jaw by the action of the retaining spring.

International Classification:

B65D 4132

US Classification:

220 902

Abstract:

The present invention comprises a sanitary beverage container having an enclosed spout for drinking liquid such as beer, milk, soft drinks or vegetable juice. The spout is automatically released from the container when it is opened by pulling back the opening tab thereof. Thus, the user's lips and mouth can use the drinking spout without contacting the top or walls of the container while drinking the contents from the container, thereby avoiding contamination and bacteria frequently associated with the top and sides of the container.

International Classification:

B25B 1328

US Classification:

81 99

Abstract:

A closed end jaw wrench comprising a body member having an upper jaw disposed at one end and a locking member at the other end thereof, a handle member pivotally connected to the body member, a closed end jaw forming a hexagon pivotally connected to the body member, biasing spring disposed between the body and the handle for biasing the handle away from said body, the handle containing a lever end portion which slidably engages a surface of the closed end jaw for separating the upper jaw of the body from the lower jaw of the closed end jaw through the releasing of the handle from the body against the bias of the extension spring, and a retaining spring attached at one end to the body and at the other end of the spring engaging space of the closed end jaw, whereby, when the handle is squeezed, the upper jaw of the body is caused to close toward the lower jaw by the action of the retaining spring.
