Filed: 1935-11-12
Abstract: 465,210. Cylindrical grinding-machines. CHURCHILL MACHINE TOOL CO., Ltd., and ASBRIDGE, H. H. Nov. 12, 1935, No. 31253. [Class 60] In a cylindrical grinding-machine wherein the work is carried by a table which reciprocates past a grihding- wheel a, the wheel is fed into the work at a continuously diminishing rate. The wheel is mounted in a head b movable on transverse ways c and having thereon a rack d engaged by a pinion e on a 'shaft f carrying a worm-wheel g and journalled in a slide h, the wheel g being engaged by a worm j splined on a shaft i operated by a hand wheel k. The slide h is pivoted at h<1> to a link m pivoted to a crank n on a shaft o, the crank having teeth n<1> thereon engaging a rack p on the rod q of a piston r movable in a cylinder s, fluid being supplied to the cylinder through a valve t from a pump w; the valve may be operated by a handle v or a solenoid u. Outward movement of the rod p is limited by its contact with a piston z in a cylinder y, fluid being supplied to the cylinder through a non-return valve x, and allowed to leak off slowly through a valve 4, so that the piston z acts as a dash-pot. The piston carries a rod 5 provided with nuts 7 to limit the outward movement of the piston and with an electric contact 6, which, when it engages a contact 8, closes the circuit of the solenoid u. In operation, on moving the valve t, the piston r moves outwards thus causing the wheel a rapidly to approach the work until, just prior to, or upon the engagement of the wheel with the work, the rod q engages the piston z, whereby the rate of movement of the piston r is diminished. The feed of the wheel continues at a, continuously diminishing rate owing to the pivot m<1> coming into line with the pivot h<1> and the shaft o until, upon their coming exactly into line the contacts 6, 8 are closed and the solenoid u moves the valve t and reverses the movement of the piston r, its inward movement being accelerated by the pressure on the piston z.
