Hose Couplings. 



No. 958. Patent Hose Coiijjling. — Gaylord Coupling Company, 

 New York. 



"We have carefully examined and experimented with this cou]')ling 

 to satisfy ourselves as to its securit}^, as to its being liquid tight, and 

 and as to the time required for connecting and disconnecting hose 

 pipe with it. We are satisfied that it is secure against accidental 

 derangement, such as might occur in the dragging of hose pipe at 

 fires ; that it is reliable as^to being water tight, and that with it hose 

 can be coupled and uncoupled with great ease and rapidity. We 

 recommend tliat the exhibitors be awarded a first premium for the 

 best hose coupling. 



No. 1162. Em])iTe Coupling. — Taylor & Cuurtlandt, New York 

 city. 



We have also carefully examined this coupling. It appears to be 

 reliable as to being a liquid-tight coupling, but we were not impressed 

 with its security against its being deranged when subjected to the 

 rough usage of a fire department. As a coupling for stationary pipes 

 we have no doubt of its efiiciency, and we therefore recommend that 

 the exhibitors be awarded a second premium for a hose coupling. 



Hose Pipe Nozzle. 



No. 957. Patent AdjustaUe Douhle- jointed Hose Pij)e Kozzle. — 

 W. D. Tcwksbury, New York city. 



We were not satisfied as to the necessity of a universal jointed hose 

 pipe nozzle of this charactGr. It might be useful in a cramped place, 

 where it W(juld be difficult to move the hose pipe, so as to direct the 

 stream in any given direction ; but we think a person would need 

 considerable practice to use tlie device properly, as, without care, he 

 would be likely to direct the stream upon himself as upon any other 

 object. 



Hose Pipe Spkinklek. 



No. 959. Hoxe Pipe SpnnUer.—\Y. H. Ilaight, New York city. 



This hose pipe nozzle is so constructed that l)y turning, in greater 

 or less degree, a milled nut at the end of the nozzle the fiow of Avater 

 may be entirely stopped, or caused to emerge in a solid stream, or
