The ion of our ners . of thoso Interested in
Water Works, Gas Works or Mines is respectfully called to our very important Improvement in the construction of Stop Valves (or Gates), They
differ froin all others in that the inner faces arc perfectly parallel, therefore when the Gate or Valve isto ho opened, at the first movement of tho
serew the center hlock (see cut) releases the disks frum thcir bearings, so
that they will movo casily and prevent the wearing of the inner faces,
This Gatohas proved very efficlent in Pipes of all slzes, and under any
pressure and froin its double form and perfect joint formation is especially
valuable for use in large Pipes tor water, steam and gas, and froin its
avoidance of any wedge shape canuot jam at any point {see cut).
_ The &. & B. Valves (or Gates) have no equal in simplicity of construe
tion_of all working parts, case of acccss for repairs, and durahility.
_., We have recently enlarged and fitted up our Brass Foundry and Shop
with ali the latest improved Tools and Machinery, thus greatly increasing
our facilities for rapidly executing orders for all sizes of Stop Valves (or
Gates) from three-inch to four feet In diameter, or any size, to order. We
guarantee them to give better satisfaction, cost Icss money, aod last
longer than any other Valve in use.
_ We arc al+o prepared to execute all orders iu Brass Work for Browerles,
Distillerles, Piumbers, Gas aud Mining Apparatus, Ship Work, Soda Apparatus, Steam Fittings, Meters, Gauges aud Indicators. Alsoin Machine
Pattern and Model Making, and Clock Work. Gearcutto order. Brasé
