Benthic foraminiferal stable isotope stratigraphy of Site 846 : 0-1.8 Ma

A new fireplace grate comprises a stationary open-front lower frame which is U-shaped in plan and has a rectangular grill movably mounted on it by a hinge connecting the superposed rear members of the grill and lower frame, thereby allowing the grill to be tilted up, with its front raised, to facilitate removal of ashes forwardly from the hearth. Log-supporting grate bars in laterally spaced parallelism have their ends removably seated in aligned slots in the front and rear members of the grill. In one embodiment the grate bars overlie in spaced protective relation an equal number of removable tubes having their rear ends detachably sleeved on nipples forwardly projecting from an air-supplying manifold which forms the rear member of the lower frame, with the front ends of the tubes removably bracketed in hangers depending from the front member of the grill and open for discharge of heated air.
