Abstract
Abstract An endpiece for a vacuum hose of a central vacuum system. There is a body having first and second ends. A nozzle projects outwardly from the first end and to go into an inlet valve of a central vacuum system. An opening in the second end receives the vacuum hose. A pathway through the body, communicates the nozzle and the opening in the second end. A connector on the body is generally adjacent the first end and a conductor joins the connector to the second end so that electrical current can be conducted from the connector to the second end of the body.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
139 words
An endpiece for a vacuum hose of a central vacuum system comprising: a body having first and second ends; a nozzle projecting outwardly from the first end and adapted to be received in an inlet valve of a central vacuum system; an opening in the second end to receive the vacuum hose; a pathway through the body communicating the nozzle and the opening in the second end; connector means on the body, generally adjacent the first end comprising a pair of prongs located in a protective cavity formed integrally with the body that opens toward said second end and extends away from the inlet valve to allow connection to an electrical power source; the second end being electrical connected to the connector means whereby electrical current is conducted from the connector means to the second end of the body.
Claim 2
Dependent Claim
139 words
An endpiece for a vacuum hose of a central vacuum system comprising: a body having first and second ends; a nozzle projecting outwardly from the first end and adapted to be received in an inlet valve of a central vacuum system; an opening in the second end to receive the vacuum hose; a pathway through the body communicating the nozzle and the opening in the second end; connector means on the body, generally adjacent the first end comprising a pair of prongs located in a protective cavity formed integrally with the body that opens toward said second end and extends away from the inlet valve to allow connection to an electrical power source; the second end being electrical connected to the connector means whereby electrical current is conducted from the connector means to the second end of the body.
Claim 3
Dependent Claim
44 words
An endpiece as claimed in claim 1 including a hose extending from the second end, and a cable associated with the hose that is electrically connected, to the second end of the body whereby current is conducted from the connector means to the cable.
