Abstract:

A screw feeding apparatus, which is designed for use with power tools, has a casing for holding screws, a platform slidably disposed in the casing for supporting and advancing the screw, a chamber assembly and a clamp assembly. In particular, the chamber assembly has an elongated cylinder for guiding the screw into a work surface. The clamp assembly is situated in the chamber assembly so that each screw from the casing is properly positioned for engaging a screwdriver bit. The screw feeding apparatus also includes a loading sleeve coupled to a rear cylinder mounted on the rear end of the chamber assembly. When the loading sleeve is retracted with respect to the rear cylinder, a screw is loaded into the chamber assembly.

International Classification:

B25B 2310

US Classification:

81453

Abstract:

A fastener holding device is designed for use with power or hand tools. The device securely engages a fastener, such as a screw, and automatically disengages the fastener when the device is pushed against a work surface. The device includes a driving bit assembly which has a socket on one end for holding a driving bit and has a polygonally shaped portion on the other end for mounting in a power drill. The device further includes a retaining member adapted to be placed on the driving bit assembly and a sleeve member adapted to be placed on the retaining member. The retaining member can be equipped with various engaging assemblies, such as brackets, bearings and pins, to securely engage the fastener. The position of the sleeve member in relation to the retaining member allows the fastener to be either engaged or disengaged with respect to the driving bit.

International Classification:

B05B 901

US Classification:

239526

Abstract:

A spray nozzle adapter is used with a conventional spray nozzle having a nozzle plug for regulating the flow of fluid in response to a control lever. The spray nozzle adapter has an intake coupler having an axially extending cylindrical wall defining an intake orifice constructed to couple to the spray nozzle, a shaft coupled to the intake coupler and a valve assembly coupled to the nozzle plug and disposed in the fluid passage of the first shaft for controlling the flow of fluid from the spray nozzle in response to movement of the spray nozzle control lever. The valve assembly includes a valve and a lever coupled to the valve. The valve has a plug for controlling the flow of fluid from the outlet orifice. The lever is securely coupled to the nozzle plug of the spray nozzle to relay the movement of the nozzle plug to the valve. The spray nozzle adapter also has a cone-shaped deflector mounted to the intake coupler to substantially surround the shaft.

Appl. No.:

9/096058

Inventors:

Ki Su Han - Rowland Heights CA

International Classification:

B65D 2508

US Classification:

206222

Abstract:

A disposable lid is used with a container has pre-stored additives such as sugar or cream. The base member has at least one compartment region which has a sealed outlet and a cover sealing the compartment region to prevent the additive from exiting the compartment region. When the cover is actuated, the outlet breaks open and allows the additive in the compartment region to flow into the container. The outlet in the base member projects from the base member and preferably has troughs formed in the outlet. The outlet is arranged under the cover, and when the cover is depressed the outlet opens at the troughs to allow the content to exit out of the compartment region. The cover is preferably made of a flexible material to permit the outlet to be depressed by applying pressure on the cover. The compartment region of the base member is formed by raised walls surrounding the compartment region, the cover being affixed to top of the raised wall to create an air tight seal.

Ki Su Han - Rowland Heights CA

International Classification:

B65D 5502

US Classification:

215227

Abstract:

A disposable lid has a flexible disk-like body and at least one slot opening formed in the body. The slot opening is adapted to receive a small container containing additives, such as sugar and cream. The slot opening is defined by a plurality of intersecting lines which break open upon application of predetermined pressure. The lid also has at least one protrusion formed near the slot opening to create an opening in the container as the container is inserted into the slot opening. The small additive container described above preferably has an elongated body which is adapted to be inserted into the slot opening of the lid through the intersecting lines. The elongated body is inserted into the slot opening, a release opening is formed in the elongated body of the additive container to release the content. The elongated body of the additive container used for the above lid has a break line which breaks open to release a content contained in the elongated body when a sharp object or a protrusion is pressed against the break line. The protrusion of the lid and the break line of the additive container are aligned so that when the additive container is inserted into the slot opening, the protrusion causes the break line to break open.
