Abstract
Abstract A hose nozzle assembly comprising a hollow metal body including an elongated hand grip portion having socket means on one end thereof constituting a water inlet for connection with a hose end and an elongated flow control element mounted in the hollow metal body for movement into different positions for controlling the flow of water from a water outlet in the body, a pair of insulating hand grip protector parts disposable with respect to each other in cooperating surrounding relation to the hand grip portion of the nozzle body and fasteners for operatively fixedly securing the parts in such surrounding relation, the parts in such surrounding relation including (1) interior surfaces cooperating with surrounding exterior surfaces of the hand grip portion of the body to define a plurality of flow channels open to the atmosphere for the dissipation of heat or cold by flow therethrough and (2) exterior surfaces for manual engagement by an operator during use so as to prevent manual contact with the hollow metal body when an extremely hot or cold liquid is flowing therethrough.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
245 words
In a hose nozzle of the type comprising a hollow metal body including an elongated hand grip portion having socket means on one end thereof constituting a water inlet for connection with a hose end and a barrel portion extending from the opposite end of said hand grip portion having a water outlet therein, an elongated flow control element mounted in said barrel portion for movement into different positions for controlling the flow of water from said outlet, and an actuating member carried by said body in a position to be manually engaged by an operator gripping said hand grip portion and operatively connected with said element for effecting the flow controlling movements of said element, the improvement which comprises in combination therewtih a plurality of insulating hand grip protector parts disposable with respect to each other in cooperating surrounding relation to the hand grip portion of the nozzle body and an adjacent section of said barrel portion, and means for oepratively fixedly securing said parts in said surrounding relation to said body, said parts in said surrounding relation including (1) interior surfaces cooperating with surrounded exterior surfaces of said body to define a plurality of flow channels open to the atmosphere for the dissipation of heat or cold by flow therethrough and (2) exterior surfaces for manual engagement by an operator during use so as to prevent manual contact with said hollow metal body when an extremely hot or cold liquid is flowing therethrough.
Claim 2
Dependent Claim
