American engineer and railroad journal . projecting ends of the crossrail, which is 42ins. deep and nearly 23 ft. long, and by these motors the sad-dles on the crosshead and the slides on the saddles can bemoved to any desired point at a rapid rate and with greataccuracy. The crosshead itself is lifted by a motormounted on top of one of the housings, provided with anelectric brake to prevent the load from running down. Thevertical slide rests are counterbalanced, have power feed onthe face of the upright and a power crossfeed which may beeither horizontal or inclined through a wide angle above andbelow the horizontal. The lubrication of the massive table is a matter of greatimportance in a machine of this kind, and it is here accom-plished by a centrifugal pump forcing oil over the bearingsunder the table, the arrangement of oil grooves being such asto insure a thorough distribution over the entire troughs are arranged to extend beyond the furthest mat, 1902.

The housings are of box construction and measure 30 on the face and 19% ft. high, and nearly 10 ft. deep in thedirection of the length of the bed. It is said that the methodof driving is peculiarly successful, it being possible to stopand start the table by hand at wiU and to reverse promptly, sothat the table may be used with u very short stroke. The illustration does not show the vertical slide rests onthe uprights, one being obscured by the intervening bed andtable and the other having been removed for attachment tothe auxiliary upright shown in a separate illustration. Thisupright is used in finishing work too wide to pass betweenthe housings and is carried upon the floor plate shown in theillustration, power for feed being derived from the squareshaft on the left hand housing for a
