Abstract
Abstract This invention relates to installation of fire sprinkler systems. In particular the present invention provides a means of installing such system before or after a ceiling has been fixed in a building. Essentially the present invention provides a water dropper pipe, a sprinkler attached to the dropper pipe and an escutcheon means. In effect, the present invention allows the sprinkler system to be installed at the most convenient time during the building operation. The escutcheon means being positioned over the sprinkler only after positioning of the ceiling such that the escutcheon means abuts against the ceiling thereby covering the immediate area between the sprinkler and the ceiling.

Claim 11
Dependent Claim
51 words
The sprinkler assembly as claimed in claim 7 wherein the spacer member is a collar member comprising a cylindrical portion the uppermost part of which abuts with the said dropper conduit and a flange portion on the lower part of the cylindrical portion, said flange portion abuts with said escutcheon means.
Claim 12
Dependent Claim
62 words
The sprinkler assembly as claimed in claim 7 wherein the spacer member is a collar having a cylindrical portion the uppermost part of which abuts with the dropper conduit, a flange portion on the lower part of the cylindrical portion and a plurality of tongues extending radially outwardly from the flange portion, said flange portion and tongues abutting the said escutcheon means.
Claim 13
Independent Claim
127 words
A method of installing a sprinkler including the following operations: positioning an insert and another insert around the portion of the sprinkler which is to be attached to a sprinkler dropper pipe, attaching the sprinkler to said dropper pipe such that the said another insert abuts the dropper pipe at one end thereof and abuts the first said insert at the opposite end thereof, installing a ceiling means having an aperture therein to permit the passage of said sprinkler therethrough, and inserting a cover plate having a flange thereon into said aperture such that said flange abuts against the said ceiling means and substantially covers the periphery of said aperture such that the first said insert abuts the inside of the cylindrical portion of said cover plate.
