Abstract
Abstract A hanger for insulated pipe with a device for temporarily holding the pipe at its proper elevation and grade prior to the application of insulation and used in conjunction with a special connection between the hanger and a hanger rod by which it is suspended, which connection enables the hanger rod to swing upon expansion of the pipe with the hanger remaining in its normal vertical position without damaging the insulation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod providing a flat surface upon which said portion rests, a line bearing area between the horizontal portion and the adjustable means enabling the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by an elongated deformation on the horizontal portion of the hanger, the elongated deformation being perpendicular to the pipe supported by the hanger.
Claim 2
Dependent Claim
90 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod providing a flat surface upon which said portion rests, a line bearing area between the horizontal portion and the adjustable means enabling the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by an elongated deformation on the horizontal portion of the hanger, the elongated deformation being perpendicular to the pipe supported by the hanger.
Claim 3
Dependent Claim
27 words
The hanger of claim 1 in which the adjustable means includes at least one nut threaded on the hanger rod, and a washer forming said flat surface
Claim 4
Dependent Claim
133 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod upon which said portion rests, a line bearing area between the horizontal portion and and the adjustable means to enable the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by deformation of the horizontal portion of the hanger, the adjustable means including at least one nut threaded on the hanger rod, and a washer between the nut and the bearing area with spacer means insertable temporarily between the washer and horizontal portion to raise the hanger a distance equal to the thickness of insulation to be installed on a pipe after it is supported by the hanger.
Claim 5
Dependent Claim
133 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod upon which said portion rests, a line bearing area between the horizontal portion and and the adjustable means to enable the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by deformation of the horizontal portion of the hanger, the adjustable means including at least one nut threaded on the hanger rod, and a washer between the nut and the bearing area with spacer means insertable temporarily between the washer and horizontal portion to raise the hanger a distance equal to the thickness of insulation to be installed on a pipe after it is supported by the hanger.
Claim 6
Dependent Claim
31 words
The hanger of claim 4 in which the spacer is a U-shaped member capable of being positioned to embrace the rod after pipe is installed and adjusted to a desired elevation.
Claim 7
Dependent Claim
28 words
The hanger of claim 4 in which the spacer means is shaped to prevent dislodgement from its operable position without raising the hanger with respect to the rod.
Claim 8
Dependent Claim
34 words
The hanger of claim 5 in which the means to prevent dislodgement consists of an irregular configuration in at least one edge of the U-shaped member to prevent sliding movement in a dislodging direction.
Claim 9
Dependent Claim
93 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod including a washer upon which said portion rests, a line bearing area between the horizontal portion and the adjustable means enabling the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by an elongated deformation on one of the horizontally disposed hanger portions and the washer, the elongated deformation being perpendicular to the pipe, supported by the hanger.
Claim 10
Dependent Claim
93 words
A pipe hanger which has a generally horizontally disposed portion perforated for reception of a hanger rod and adjustable means on the rod including a washer upon which said portion rests, a line bearing area between the horizontal portion and the adjustable means enabling the hanger to rock with respect to the rod and remain vertical when the rod swings, the line bearing area being formed by an elongated deformation on one of the horizontally disposed hanger portions and the washer, the elongated deformation being perpendicular to the pipe, supported by the hanger.
