In said patent Radial Truck No. 673, PLAYER, of Dunkirk, N. Y., assignor to the Brooks Locomotive Works. The invention relates to so called ra-dial trucks for locomotive engines andother railroad rolling stock in which lat-eral motion or radial movement of abearing axle of the vehicle relatively tothe main frame thereof is provided forto facilitate and reduce strains in thepassage of the vehicle into, through, andfiom cuived poitions of the the feed screw is shown as ha\mg a con-stantly decreasing taper and pitch fromthe outer to the inner end, and in stok-ers made in accordance with said patentit has been customary for the inner sidewalls of that portion of the coking orfuel chamber in which the screw rotatesto leave or break contact with the screwat a plane drawn approximately throughthe axis thereof. By experiment I havefound that the radial or upward feed ofthe fuel takes place almost entirely onthat side of the screw on which thethread rises, such feed being almost tan-gential, and that on the descending sidethe fuel at times tends to cake or accu-mulate and is fed forward without risingsubstantially, and as the pitch and taperof the screw decrease the fuel experi-ences a constantly increasing ditficultyin radial or upward movement, any ten-dency to which is partially impeded fromthe bottom by the boss or stem of thescrew, and at times so much power is re-quired to drive the screw that it is suf-
