Abstract
An adapter converts a fastener driving tool into an automatic (multiple shots per second) pneumatic fastener driving tool. The adapter is mounted to the top of the frame body of a pneumatic fastener driving tool, in which the adapter has a control valve that automatically moves to direct pressurized air to different passageways in the tool body in a repetitive cyclic manner. The speed of actuation can be adjusted by the user.
Claims18
An adapter for use with a fastener driving tool, comprising:
- (a) a housing having a plurality of passageways that allow gas flows to pass therethrough, and including an opening that is in fluidic communication with said plurality of passageways, said opening being sealed by a first bushing proximal to a left end of the opening, and by a second bushing proximal to a right end of the opening;
- (b) a control valve that is movable within said opening, said control valve having a left end portion and a right end portion, said control valve including a left land proximal to said left end portion, a right land proximal to said right end portion, and a middle land between said left land and said right land;
- (c) said opening including a left gas passageway that exists between said left land and said middle land of the control valve;
- (d) said opening including a right gas passageway that exists between said right land and said middle land of the control valve;
- (e) a spring that is positioned within the opening, proximal to said left end portion of the control valve;
- (f) a first passageway, of said plurality of passageways, that is in fluidic communication with said left gas passageway of the opening;
- (g) a second passageway, of said plurality of passageways:
- (i) that is in fluidic communication with said left gas passageway of the opening if said control valve resides at a first position that does not compress said spring;
- and
- (ii) that is in fluidic communication with said right gas passageway of the opening if said control valve resides at a second position that compresses said spring;
- (h) a third passageway, of said plurality of passageways, that is in fluidic communication with said right gas passageway of the opening;
- (i) a fourth passageway, of said plurality of passageways, that is in fluidic communication with said right end portion of the control valve;
- and
- (j) a head screw that is adjustable to control gas flow through said fourth passageway in order to adjust a rate at which said control valve operates;
- wherein, said first, second, third, and fourth passageways of said plurality of passageways are the only passageways that are in fluidic communication with said opening between said first bushing and said second bushing.

An adapter for use with a fastener driving tool, comprising:
- (a) a housing having a plurality of passageways that allow gas flows to pass therethrough, and including a sleeve that is in fluidic communication with said plurality of passageways, said sleeve being sealed by a first bushing proximal to a left end of the sleeve, and by a second bushing proximal to a right end of the sleeve;
- (b) a control valve that is movable within said sleeve, said control valve having a left end portion and a right end portion, said control valve including a left land proximal to said left end portion, a right land proximal to said right end portion, and a middle land between said left land and said right land;
- (c) said sleeve including a left gas passageway that exists between said left land and said middle land of the control valve;
- (d) said sleeve including a right gas passageway that exists between said right land and said middle land of the control valve;
- (e) a spring that is positioned within the sleeve, proximal to said left end portion of the control valve;
- (f) a first passageway, of said plurality of passageways, that is in fluidic communication with said left gas passageway of the sleeve;
- (g) a second passageway, of said plurality of passageways:
- (i) that is in fluidic communication with said left gas passageway of the sleeve if said control valve resides at a first position that does not compress said spring;
- and
- (ii) that is in fluidic communication with said right gas passageway of the sleeve if said control valve resides at a second position that compresses said spring;
- (h) a third passageway, of said plurality of passageways, that is in fluidic communication with said right gas passageway of the sleeve;
- and
- (i) a fourth passageway, of said plurality of passageways, that is in fluidic communication with said right end portion of the control valve;
- (j) a head screw that is adjustable to control gas flow through said fourth passageway in order to adjust a rate at which said control valve operates;
- wherein, said first, second, third, and fourth passageways of said plurality of passageways are the only passageways that are in fluidic communication with said sleeve between said first bushing and said second bushing.

An adapter, configured to be mounted to a single shot fastener driving tool, that converts the single shot fastener driving tool to an automatic multiple shot fastener driving tool, comprising:
- (a) a housing having a plurality of passageways that allow gas flows to pass therethrough, and including an opening that is in fluidic communication with said plurality of passageways, said opening being sealed by a first bushing proximal to a left end of the opening, and by a second bushing proximal to a right end of the opening;
- (b) a control valve that is movable within said opening, said control valve having a left end portion and a right end portion, said control valve including a left land proximal to said left end portion, a right land proximal to said right end portion, and a middle land between said left land and said right land;
- (c) said opening including a left gas passageway that exists between said left land and said middle land of the control valve;
- (d) said opening including a right gas passageway that exists between said right land and said middle land of the control valve;
- (e) a spring that is positioned within the opening, proximal to said left end portion of the control valve;
- (f) a first passageway, of said plurality of passageways:
- (i) that is in fluidic communication with said left gas passageway of the opening;
- and
- (ii) that is configured to be placed in fluidic communication with a trigger of said tool;
- (g) a second passageway, of said plurality of passageways:
- (i) that is configured to supply gas flow to a firing valve of said tool;
- (ii) that is in fluidic communication with said left gas passageway of the opening if said control valve resides at a first position that does not compress said spring;
- and
- (iii) that is in fluidic communication with said right gas passageway of the opening if said control valve resides at a second position that compresses said spring;
- (h) a third passageway, of said plurality of passageways:
- (i) that is in fluidic communication with said right gas passageway of the opening;
- and
- (ii) that is configured to receive gas flow from a source of gas;
