Abstract
Abstract Disclosed in an apparatus and method for changing or replacing domestic or residential-type gas meters without interrupting the gas supply to the service line downstream of the meter and obviating the necessity of shutting off the gas water heater, furnace on other gas appliances in the dwelling. The apparatus includes a member which is clamped around the outlet fitting of the gas meter. A slide carried by the member is moveable to simultaneously close the meter outlet and to introduce an alternate supply of gas to the service line downstream of the meter. After the normal gas supply to the meter inlet is shut off, the meter is removed and a replacement meter is installed by attaching its inlet to the gas supply line and its outlet to aforementioned member. The slide is then again moved to simultaneously place the meter outlet in communication with the service line and to shut off the alternate gas supply.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
265 words
A device for facilitating the disconnection and reconnection of a gas meter having inlet and outlet fittings connected to a supply pipe and a service pipe respectively, said device comprising a top plate having an aperture extending therethrough sized to accommodate said gas meter service pipe, said plate being adapted to be releasably clamped about the gas meter service pipe with the gas meter outlet fitting extending substantially to said aperture at the underface of said top plate, a slide plate underlying said top plate with the adjacent faces of the plates contiguous, said slide plate being supported by said top plate, a translating member for moving said slide plate in a plane parallel to the plane of said top plate, a depression in the upper face of said slide plate forming a supply chamber in conjunction with the contiguous underface of the top plate, a supply passage formed in said top plate for providing an alternate supply of gas to said chamber, said chamber registering only with said supply passage when said slide plate is in a first position with relation to said top plate and registering with both said supply passage and said top plate aperture when moved to a second position by said translating member, said slide plate permitting the meter fitting to be moved out of registration with said top plate aperture and said service pipe and simultaneously to move said supply passage into registration with the top plate aperture and said service pipe as said translating member moves said slide plate from its said first to its said second position.
Claim 2
Independent Claim
265 words
A device for facilitating the disconnection and reconnection of a gas meter having inlet and outlet fittings connected to a supply pipe and a service pipe respectively, said device comprising a top plate having an aperture extending therethrough sized to accommodate said gas meter service pipe, said plate being adapted to be releasably clamped about the gas meter service pipe with the gas meter outlet fitting extending substantially to said aperture at the underface of said top plate, a slide plate underlying said top plate with the adjacent faces of the plates contiguous, said slide plate being supported by said top plate, a translating member for moving said slide plate in a plane parallel to the plane of said top plate, a depression in the upper face of said slide plate forming a supply chamber in conjunction with the contiguous underface of the top plate, a supply passage formed in said top plate for providing an alternate supply of gas to said chamber, said chamber registering only with said supply passage when said slide plate is in a first position with relation to said top plate and registering with both said supply passage and said top plate aperture when moved to a second position by said translating member, said slide plate permitting the meter fitting to be moved out of registration with said top plate aperture and said service pipe and simultaneously to move said supply passage into registration with the top plate aperture and said service pipe as said translating member moves said slide plate from its said first to its said second position.
Claim 3
Dependent Claim
40 words
A device as claimed in claim 1 in which a layer of resilient material is interposed between the underface of said top plate and the adjacent upper face of said slide plate to provide a resilient interface between said surfaces.
Claim 4
Dependent Claim
36 words
A device as claimed in claim 1 in which a purging opening is provided in said top plate registering with the meter fitting when the meter fitting is out of register with said top plate aperture.
Claim 5
Dependent Claim
26 words
A device as claimed in claim 1 in which said slide plate is provided with a curved side surface adapted to engage the meter inlet fitting.
Claim 6
Dependent Claim
33 words
A device as claimed in claim 1 in which the support for said slide plate comprises a bottom plate secured in spaced relation to said top plate with said slide plate interposed therebetween.
Claim 7
Dependent Claim
63 words
A device as claimed in claim 5 in which said translating member includes a rotatable, threaded spindle journalled for rotation between said top and bottom plates and extending parallel thereto, the threaded portion of said spindle accommodating a correspondingly threaded portion of said slide plate whereby upon rotation of said spindle said slide plate is moved between its said first and second positions.
