Abstract

375,715. Combined turning, boring, and milling machines. KEARNS & CO., Ltd., H. W., Broadheath, near Manchester, and KEARNS, J. R. C., Orrish Meres, Harboro Road, Ashton-on-Mersey. Dec. 29, 1931, No. 35888. [Class 83 (iii).] Boring-bar machines.-A combined horizontal boring and milling machine has alternative constant speed and variable speed drives for the feed mechanism either of which may operate through a common change speed feed gear. The main driving pulley 1 rotates either the wheel 8 or the wheel 5 in the forward or reverse direction, respectively, according to the position of the clutch 3, thus driving through helical gears 10, 11 the shaft 12 which extends upwards from the bed a to the vertically sliding head d, Fig. 2. The shaft 15 driven by helical gears from shaft 12 drives the main change-speed gear (not shown) by means of which the spindle e is rotated at various speeds. The drive for the feed mechanism is taken either through wheels 16, 17 from the shaft 12, or from spindle e through wheels 20, 22 according to the disposition of the dog clutch 23, thus allowing for constant speed and variable speed feeds respectively, the common reversing and change speed mechanism completing the train to the shaft 25 from which the feed motions for the various movable members, such as the table b, are taken. An end-forcing slide may be fitted to the head and fed by either the constant speed or variable speed source.
