We build Steam Feeds of all sizes and poweis, building direct feed with cylinders of v inch. 10 inch, 11 inch and 12 inch bore, and as long as desired, with and without automa- tic cut-off device. For these feeds, or other feeds of like character, we furnish the model "D" valve, which is considered to be the best valve made for the purpose, showing the valve at the front end of the feed. This valve is of the type best known as double valves, one being used at either end of the feed, and making a saving over the old sty'e of centre valve of 15 per cent, in steam. We unhesitatingly pronounce this valve to be the best ever designed. It is absolutely bal- anced, does not stick or kick, has larger steam openings than any other valve made for correpond- ing sizes of pipe, is economical in the use of steam, and handles the largest and longest feeds, under any pressure, with perfect ease and accuracy. We have also designed a new style of stuffing box which is a great saving in packing, and has an outer support, and is fitted with an oil well, filled with felt or waste which keeps the piston thoroughly lubricated. Improved DoubIe=Tooth or Boss Dogs The accompanying cuts fully illustrate our Improved Double-Tooth Dogs with inserted teeth, making the teeth them- selves of the finest tool steel. This allows them to be drawn to a slender point that will penetrate without crowd- ingthe log or board away from the car- riage The teeth in case of bending or breaking can be replaced in a few mo- ments, and without having to take the whole dog case apart — an operation requiring pn hour or more. These Double-Tooth Dogs are con- trolled by a wrought iron lever that can be bent to suit the operator, and this lever is held by a spring, positively in or out, so that there is no danger of the Dogs pushing out toward the saw.
