Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
227 words
A portable inflator comprising, a container housing a supply of gas under pressure, said container having an opening formed in a wall thereof, a plug secured within the opening in said container wall and having a bore extending therethrough in communication with the interior of said container, a first valve member seated within said bore adjacent the inner end thereof and having a passageway extending therethrough, a second valve member having a stem extending loosely through the passageway of said first valve member and terminating in a head exposed to the interior of said container and normally seated on said first valve member to close said passageway, a stationary flat-faced gasket having an aperture and firmly held across the bore of said plug and a valve actuator held captive for free axial movement within the aperture of said gasket remote from said first valve member and having an actuating portion for actuating a valve in the article to be inflated, said portion extending through said aperture, the end of the valve stem of the article to be inflated being seated in sealing contact on the flat face of said gasket, said actuator being independently movable axially into contact with the stem of said second valve member to unseat the head thereof and thereby open the passageway of said first valve member to release gas from the container.
Claim 2
Dependent Claim
227 words
A portable inflator comprising, a container housing a supply of gas under pressure, said container having an opening formed in a wall thereof, a plug secured within the opening in said container wall and having a bore extending therethrough in communication with the interior of said container, a first valve member seated within said bore adjacent the inner end thereof and having a passageway extending therethrough, a second valve member having a stem extending loosely through the passageway of said first valve member and terminating in a head exposed to the interior of said container and normally seated on said first valve member to close said passageway, a stationary flat-faced gasket having an aperture and firmly held across the bore of said plug and a valve actuator held captive for free axial movement within the aperture of said gasket remote from said first valve member and having an actuating portion for actuating a valve in the article to be inflated, said portion extending through said aperture, the end of the valve stem of the article to be inflated being seated in sealing contact on the flat face of said gasket, said actuator being independently movable axially into contact with the stem of said second valve member to unseat the head thereof and thereby open the passageway of said first valve member to release gas from the container.
Claim 3
Dependent Claim
42 words
A portable inflator for tires or the like according to claim 1, wherein the plug has an annular skirt surrounding and projecting outwardly from the valve actuator and circumferentially engageable with the stem of a tire valve during the tire inflation operation.
Claim 4
Dependent Claim
39 words
A portable inflator for tires or the like according to claim 1, wherein the plug has an annular outwardly open and internally threaded portion surrounding the valve actuator for reception on the threaded outer end of a tire valve.
Claim 5
Dependent Claim
37 words
A portable inflator according to claim 1, wherein the actuator terminates at its inner end in a head of greater diameter than the opening in the gasket and of smaller diameter than the bore of the plug.
Claim 6
Dependent Claim
221 words
A dispensing valve assemblage for use with a pressurized container, said valve assemblage comprising, a closure for the container having a bore extending therethrough, a first valve member seated within said bore adjacent the inner end thereof and having a passageway extending therethrough, a second valve member having a stem extending loosely through the passageway of said first valve member and terminating in a head normally seated on said first valve member to close said passageway, a stationary flat-faced gasket having an aperture and firmly held across the bore of said closure, and a valve actuator held captive for free axial movement within the aperture of said closure remote from said first valve member and having an actuating portion for actuating a valve in the article to be inflated, said portion extending through said aperture, the end of the valve stem of the article to be inflated being seated in sealing contact on the flat face of said gasket, said actuator being independently movable axially into contact with the stem of said second valve member to unseat the head thereof and thereby open the passageway of said first valve member, said closure having an annular, internally smooth skirt surrounding and projecting outwardly from the valve actuator and circumferentially engageable with the stem of a tire valve during the tire inflation operation.
Claim 7
Dependent Claim
221 words
A dispensing valve assemblage for use with a pressurized container, said valve assemblage comprising, a closure for the container having a bore extending therethrough, a first valve member seated within said bore adjacent the inner end thereof and having a passageway extending therethrough, a second valve member having a stem extending loosely through the passageway of said first valve member and terminating in a head normally seated on said first valve member to close said passageway, a stationary flat-faced gasket having an aperture and firmly held across the bore of said closure, and a valve actuator held captive for free axial movement within the aperture of said closure remote from said first valve member and having an actuating portion for actuating a valve in the article to be inflated, said portion extending through said aperture, the end of the valve stem of the article to be inflated being seated in sealing contact on the flat face of said gasket, said actuator being independently movable axially into contact with the stem of said second valve member to unseat the head thereof and thereby open the passageway of said first valve member, said closure having an annular, internally smooth skirt surrounding and projecting outwardly from the valve actuator and circumferentially engageable with the stem of a tire valve during the tire inflation operation.
