The fourstationary ovens, built after their owndesign, are coke fired from the rear,each oven being 8x9 feet and 7 feet in PLUMBER AND STEAMFITTER November 2, 1908 height. A transfer track shown in is used instead of a turntable, andextends almost the length of the permits the core racks to be un-loaded where the cores are stored forfuture use and the racks can also be volves problems not frequently encoun-tered by the average coremaker. Thepasting of cores is obsolete practice inradiator plants, and vents are not madewith wires. In Fig. 5, 1 shows the corebox of a four column core. A core pan.

The sand is delivered into a pit locat-ed at one end of the shop and is elevat-ed to a mixer on a raised platform bybucket conveyors. The mixer and con-veyor was installed by the StandardSand & Machine Co., Cleveland. When simihirly constructed, in which the coreis dried, is used in making the otherhalf. After the sand has been packedin the core box and the pan, the ventplate 2 is used. The vents lead to onepoint and a corresponding vent is madein the mold to permit of the escape ofthe gases through one opening. Afterthe vent plate has been applied to both them to readily leave the castings. Asthe metal very nearly covers the corethe reason for striving in this directionis apparent. A good, sharp sand isgenerally used, mixed with linseed oiland resin. In Fig. .5—3, 4, 5, 6, 7 and 8show a variety of radiator cores. Theseare made
