Feed Pumps. 



^0. 523. TliG Positive Feed Pump of J. ^Y. Cole, New York 

 citv, combines so many of the features of a good boiler feeder, occu- 

 pies so little horizontal space, is simple in the arrangement of its 

 parts, and so well calculated to prove durable, that we recommend 

 for it the award of a first premium as a reliable vertical feed pump. 

 ' No. 1206. Messrs. Wm. Sellers & Co., of Philadelphia, are, in our 

 opinion, deserving of a first premium for an injector of great excellence, 

 of unsurpassed workmanship, and one which has been thoroughly- 

 tested by long public trial. 



No. 56-i. The rotary steam pump of Messrs. H. C. Dart & Co., of 

 New York, in our estimation excells all others of its class in extreme 

 simplicity of the moving parts, uniformity of action, and great freedom 

 from unnecessary friction. We recommend for it a first premium as 

 a Rotary Boiler Feed. 



No. 179. Factory Pumj). — Bridgeport Manufacturing Company, 

 Bridgeport, Conn. 



Tliis pump is constructed upon the same principle as that in the 

 American submerged pump, made by the same manufacturers, and 

 is necessarily efficient. The pump however is constructed as a suction 

 and force pump to be driven by a belt. It is properly termed by 

 its makers, a factory pump, and we recommend that a second 

 premium be awarded its manufacturers for a factory pump. 



Hand Pcmps. 



Under this general head we class a number of pumps, which are 

 intended more especially to be operated by hand power. 



No. 475. Sink Pump. — James Coleman & Co., New Yoi-k City. 



This is a brass barrel lift pump, especially adapted for use in a sink. 

 We are unable to discover any feature in the pump which makes it 

 superior to other pumps of the same character now in the market. 



No. 179. Sinli Pump. — Bridgeport Manufacturing Company, 

 Bridgeport, Conu. 



This a novelty in tlie way of a pump. Its barrel or cylinder is 

 made of glass, wliich is supported in a shotted metallic frame. Such 

 cylinder permits the valve and plunger to be at any time inspected 

 without taking the pump apart; it also enables one at a glance to 

 discover whether or not, in freezing weather, the water has been 

 allowed to escape from the pump, by the tripping of the valve in the 

 usual way. The glass cylinder also very niateriall}' reduces friction,
