NEW WATER WORKS MACHINE.
The new Lead Joint Removing Machine, shown in illustration, is the invention of D. W. French, the well known engineer of Hoboken, N. J. This machine accomplishes a class of work which has not been attempted heretofore.
It is made to clamp upon the bell end of a pipe, branch or special, and to remove all the lead joint without hammering. The machine is also arranged so that it can be clamped to a pipe and remove the lead joints from gate valves. This latter application has advantages which must be apparent to all water and gas works superintendents, because in the case of a gate valve, it is next to impo sible to melt the lead from the bells without melting at the same time the soft metal which holds the valve seats in place, and which melts at about the same temperature as lead.
By following the works on the set screws, the machine is easily centered upon the bells.After this is done, select a cutting tool as broad on the cutting edge as the widest part of the lead joint, and put it into place. The feed is automatic. It makes no difference whether the lead joint is of the same thickness all round or not, so long as the tool is as wide as the widest part of the point. It does not matter if the tool in feeding into the bell comes into contact with theoutside of the iron plug, or the inside of the bell; the tool will remove the small amount of iron as well as the lead at the same time. In removing the lead from the bells of gate valves, the machine is clamped to the pipe in front of the joint, instead of to the bell, and the crank is then turned in the opposite direction. These machines are also of great value in taking up a line of pipe, and are operatedhe same way as in taking out a plug.
The use of this machine means: First-No loss of plugs. Second-No loss of lead, as in melting. Third-No use of wood or coke for melting. Fourth-No danger of breaking the bells by removing. Fifth-No danger of destroying valves by overheating.
These machines are for sale by Benjamin C. Smith, 275 Pearl street, New York city.

One who claims to have been a special agent sent to visit the water works of Key West, Fla., writes that the water works system of the place is deficient,in that no fresh water has been secured, although $20,000 has been expended in the attempt. closed up. There is no direct pressure system, and the water towet is fil’td only when it shows considerable depletion. Another effort will be made to secure fresh water.
The standpipe is at present filled with salt water, and the report states further that within the next year the pipes from the use of salt water will be in such a condition as to be practically
