Abstract
Abstract A spacer or emplacement former is provided to fit about a soil pipe or the like that is to be substantially embedded in or surrounded by a construction material such as concrete. The spacer reserves an annular space in the construction material immediately surrounding the pipe for the emplacement of subsequent connection or emplacement of other plumbing fixtures. The present spacer comprises a generally cup-shaped member, adapted to receive a pipe or the like telescopically, having an open end, and also having a closed but removable end. The spacer is aligned with pipes of various diameters by aligning means adjacent its closed end adapted to align the spacer with pipes of various diameters, and by means of a series of fingers that extend radially inwardly of the spacer adjacent its open end. The fingers are formed of friable material of substantial cross section and are adapted to break off at essentially any suitable radial distance within the lengths of the fingers in order to provide aligning surfaces on the ends of the fingers to accommodate inwardly of the fingers and closely fit, pipes of varying diameters to aid in aligning the spacer with such pipes. Preferably, the fingers are formed of friable foamed plastic material.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
153 words
A spacer of the character described comprising a generally cup-shaped member having a closed end and an open end adpated to receive the end portion of a pipe or the like; first pipealigning means in and supported from said cup-shaped member adjacent its closed end, said first pipe-aligning means including at least two pipe-aligning members radially spaced substantially concentrically of the cup-shaped member selectively to align pipes of a plurality of diameters either between said two pipealigning members of said first pipe-aligning means or at a side of a pipe-aligning member of said first pipe-aligning means; and second pipe-aligning means in and supported from said cup-shaped member adjacent its open end, said second pipe-aligning means including fingers comprising friable plastic material adapted to be easily broken off at essentially any longitudinal location thereof over a substantial length of said fingers to accommodate inwardly of the fingers pipes of said plurality of pipe diameters.
Claim 2
Dependent Claim
153 words
A spacer of the character described comprising a generally cup-shaped member having a closed end and an open end adpated to receive the end portion of a pipe or the like; first pipealigning means in and supported from said cup-shaped member adjacent its closed end, said first pipe-aligning means including at least two pipe-aligning members radially spaced substantially concentrically of the cup-shaped member selectively to align pipes of a plurality of diameters either between said two pipealigning members of said first pipe-aligning means or at a side of a pipe-aligning member of said first pipe-aligning means; and second pipe-aligning means in and supported from said cup-shaped member adjacent its open end, said second pipe-aligning means including fingers comprising friable plastic material adapted to be easily broken off at essentially any longitudinal location thereof over a substantial length of said fingers to accommodate inwardly of the fingers pipes of said plurality of pipe diameters.
Claim 3
Dependent Claim
210 words
A spacer of the character described comprising a generally cup-shaped member having a closed end and an open end and adapted to receive the end portion of the pipe or the like; first pipe-aligning means in said cup-shaped member adjacent its closed end, said first pipe-aligning means including at least two axially extending pipe-aligning members radially spaced substantially concentrically of said cup-shaped member selectively to align pipes of a plurality of diameters either between radially spaced pipe-aligning members of said first pipe-aligning means or at a side of a pipe-aligning member of said first pipe-aligning means; and second pipe-aligning means including fingers supporting and extending generally radially inwardly from said cup-shaped member at a location adjacent its open end, said fingers being formed of friable plastic material of substantial cross section that permits said fingers to be easily broken off at essentially any location thereof over a substantial length of said fingers to provide on the broken ends of the remaining portions of said fingers aligning surfaces that extend generally axially of and substantially parallel and in close proximity to the outside surface of a pipe having a diameter corresponding to any of said plurality of pipe diameters to align the open end portion of said spacer with said pipe.
Claim 4
Dependent Claim
210 words
A spacer of the character described comprising a generally cup-shaped member having a closed end and an open end and adapted to receive the end portion of the pipe or the like; first pipe-aligning means in said cup-shaped member adjacent its closed end, said first pipe-aligning means including at least two axially extending pipe-aligning members radially spaced substantially concentrically of said cup-shaped member selectively to align pipes of a plurality of diameters either between radially spaced pipe-aligning members of said first pipe-aligning means or at a side of a pipe-aligning member of said first pipe-aligning means; and second pipe-aligning means including fingers supporting and extending generally radially inwardly from said cup-shaped member at a location adjacent its open end, said fingers being formed of friable plastic material of substantial cross section that permits said fingers to be easily broken off at essentially any location thereof over a substantial length of said fingers to provide on the broken ends of the remaining portions of said fingers aligning surfaces that extend generally axially of and substantially parallel and in close proximity to the outside surface of a pipe having a diameter corresponding to any of said plurality of pipe diameters to align the open end portion of said spacer with said pipe.
Claim 5
Dependent Claim
40 words
The spacer of claim 1 in which one of said two pipe-aligning members of said first pipe-aligning means comprises a generally circular flange extending longitudinally of the cup-shaped member from its closed end and radially spaced from said cup-shaped member.
Claim 6
Dependent Claim
40 words
The spacer of claim 2 in which one of said tWo pipe-aligning members of said first pipe-aligning means comprises a generally circular flange extending longitudinally of the cup-shaped member from its closed end and radially spaced from said cup-shaped member.
Claim 7
Dependent Claim
53 words
The spacer of claim 1 in which said two pipe-aligning members of said first pipe-aligning means are supported by said closed end of said cup-shaped member, and in which one of said two pipe-aligning members of said first pipe-aligning means comprises pin members extending axially of the cup-shaped member from its closed end.
