TRANSACTIONS OF THE 



Adjustable Attachment for Force Pumps. 



John R. Sees, No. 10 Suflfolk street, New- York. For supplying 

 the boilers of locomotives and other engines with water to equal 

 the evaporation. The benefit of a uniform and constant supply of 

 feed water, is unquestionable. The additional expense of attaching 

 this to a locomotive, or other high-pressure engine of the same 

 power, is only fifty dollars, including the right of use, or twenty 

 dollars for the right alone, when the parties apply the improve- 

 ment themselves. 



The cut represents one attached to the ordinary pump 

 now in use; when on a locomotive in a snow storm, or when the 

 road is blocked up from other causes, a pump with the above at- 

 tachment can be worked by hand without disconnecting any part 

 of the machinery, and all danger of burning the boiler for want 

 of water is obviated. 



Water Float Gauge. 



F. A. Hoyt & Co. , Boston, Mass. The best water float 

 guage. This is a simple mechanical invention for tell- 

 ing at all times ^ the position of the water in steam 

 boilers. The advantagef claimed over others now in 

 use, are in its durability, simplicity, and its constant 

 and accurate indication of the solid water within 

 the boiler, the/oam not being dense enough to move 

 or affect the float, which being filled with compress- 

 ed air, is in no danger of loading or collapsing by the 

 pressure upon its surface. The float is also directly 

 connected with the indicating hand, by means of a 

 lever and shaft working in a steam-tight case elevated 

 above the water, so that no sediment can collect 

 Water Float Gauge about the shaft, to prcvcut its always working with 

 perfect ease and accuracy. No packing is needed, as the shaft in 

 passing through the case to connect with the indicator, forms of 

 itself, a perfectly steam-tight joint — not creating friction enough 

 to prevent its working perfectly free, at all times. It is easily - 

 applied to all kinds of steam boilers, locomotives, stationary and 

 steamboat. [.^ bronze medal awarded.
