Abstract

738,873. Rotary tool-heads. KEARNS & CO., Ltd., H. W. April 15, 1954 [May 8, 1953], No. 12865/53. Class 83 (3). A face plate a for a horizontal boring and facing machine comprises a facing slide c carrying a pair of racks g<SP>1</SP>, g<SP>2</SP>, each engaged by a worm wheel f<SP>1</SP>, f<SP>2</SP> respectively, meshing also with a common worm e formed on a cylindrical surface coaxially around the spindle b, the racks having teeth of equal but oppositelydirected inclination and arranged parallel to, but with the worm wheels, asymmetrically on opposite sides of the facing slide. The proprojection of the worm wheel teeth onto the respective rack is equal in each case, to obtain correct meshing of the worm wheels and racks and a balanced thrust on the slide. Specification 499,945 is referred to.
