  • AM FHMIM/THOG/M PHIG ammmsaomvzls PROCESS UNITED STATES BIRDSILL HOLLY, OF LOGKPORT, NEW YORK.
  • the object of the first of my improvement is to furnish water for different levels in such a way as to supply the higher level in a city without overstraining the mains and pipes in a lower level; and that of the second of my said improvements is to cause smaller mains to be successfully used as a substitute for larger, and also to provide for the more convenient cutting off of the flow of water in any particular street without interrupting it in others.
  • a A represent two forcing-pumps, placed at the source nishing a convenient opportunity for its distribution along the cross-streets by means of the distributing-pipes a a.
  • C 0 represent the hydrants or fire-plugs, placed at convenient distances, so that by means of hose attached to each water may be supplied at any point for the extinguishment of fires.
  • the pump A is intendedfor supplying the mains B which lead to the lower level, and the pump A is designed for supplying those mains B which lead to the higher level, as shown in Fig. 1.
  • the pump A supplies the lower mains B, which consume nine-tenths of the water used in the city, while one-tenth will have to be raised to the height of two hundred and twenty-five feet, which will require an additional pressure of about one hundred pounds to the inch.
  • the pump A supplies the lower mains B, which consume nine-tenths of the water used in the city, while one-tenth will have to be raised to the height of two hundred and twenty-five feet, which will require an additional pressure of about one hundred pounds to the inch.
  • the suction-pipe of the pump A may be made to communicate directly with the pumpingwell through the pipe D, and also with the discharge-pipe D of the pump A through the pipe 1), so as to take water either from said well or from said discharge-pipe.
  • the suctionpipe D has a foot-valve, d, applied to it, to prevent the escape of water from the pump A when it is being supplied from the pump A.
  • a safety-valve, o is applied to the pipe D
  • a safety-valve, h is applied to the pipe H,
  • this safety-valve opens the discharge is from the pipes which connect with the higher level into those which connect with the lower, and thus preventing a waste of power.
  • Each one of the parallel pipes is provided at its'opposite ends with valves 19, by the closing of which the water will be cut oil so that repairs can be made anywhere on that line without interfering with the current of water on any other line of pipes.
  • J represents a double-ogee frame, which is strengthened by the webbing J J and stretchers j j, and adapted for supporting upon one side of it two quarter-crank engines.
  • the piston-rods of these engines are both connected to a wrist-pin on a'crank-plate, e, the shaft 0 of which carries a spur-wheel, G, and also' the eccentric to which the slide-valve rods of the engines are applied.
  • the spur-wheel G is arranged above, and engages with a spur wheel, F, which latter is arranged above and engages with a pinion, n, shown in dotted lines, Fig. 2, which is keyed on the shaft of a rotary engine, N, and which may be thrown in and out of gear at pleasure.
  • spur-wheels E E On opposite sides of the pinion a, and keyed on the shafts g g of the force-pumps A A, are spur-wheels E E, either one or both of which it is proposed to engage with or disengage from the spur-wheel F at pleasure by means of suitable shiftingclutch'es.
  • Each of these spur-wheels E E moves a pump or set of pumps, one or both of which are intended for use on all ordinary occasions.
