KO-SHOVEL MECHANICAL STOKER A new scatter type stoker for stationary boilers has beenplaced on the market by the Goetz Company, Chicago. Thestoker is installed either directly in the upper portion of thefire door opening or immediately above the door in the boilerfront. The entering chute and plunger occupy a space but5 in. deep, and when installed in the fire door opening anew door is provided. The installation does not prevent, orinterfere in any way with firing by hand, or cleaning thefire through the fire door. The coal is fed to the hopper ofthe stoker, as shown in the photograph, and from there passesthrough a pair of agitator crushers to a rotary coal valve regulates the flow of the crushed coal to the dis-charge cylinder, where it is ejected onto the grate by meansof a spring actuated plunger, the coal passing over a water-. Ko-Shovel Mechanical Stoker Applied to a Battery of Boilers cooled deflector suitably arranged to properly scatter the coalover the grate. The rotary valve is simply a disc with two diametricallyopposite pockets which take the correct amount of coal fromthe crusher chamber and deliver it to the discharge cylinderThe plunger is driven by two compression springs and ispulled out to the charging position by means of a cam, asindicated in the drawing. The gearing is so arranged thatas the plunger is pulled back the rotary coal valve deliversits charge to the discharge cylinder. By the time the secondcam roller disengages from the second lug on the plungerthe rotary valve is closed and the coal is in the cylinder readyto be discharged. A compression spring is provided, as indi-cated, to serve as a buffer for the plunger at the end of thestroke. The stoker may be driven by either a steam engine or anelectric motor or by a belt from a line shaft. When a steame
