Title: Improvements in automatic lathes and the like
IPC: B23Q5/34
Filed: 1944-01-25
Abstract: 574,261. Lathes. HERBERT, Ltd., A., LLOYD, A. H., and KNIGHT, H. F. Jan. 25, 1944, No. 1364. [Class 83 (iii)] In an automatic lathe or like machine tool in which a cycle of operations is carried out for each predetermined angular movement of a control drum, a cam drum for actuating a slide is freely mounted on a shaft driven in timed relation to the control drum and is positively clutched thereto at the appropriate times and automatically disengaged after a predetermined angular movement by means of a control disc which is continuously driven from the said shaft. The invention is described as applied to an automatic turret lathe. A control drum shaft 12 makes one complete revolution for a cycle of the machine tool and carries a drum 14 connected by gearing and a shaft 27 to a cam drum 15 for actuating the turret slide. The cam groove on the drum is such as to cause an in-feed and an out-feed with a dwell in both the forward and rear positions for every three revolutions of 'the cam and, for a four-faced turret, the cam drum 15 is geared to rotate twelve times for a complete turn of the control drum 14. The shaft 27 also carries wormwheel 30 meshing with a worm 31 which drives the shaft 38 of a cam drum 16 through gears 33, shaft 34 and a multi-toothed setting clutch 35 which may be disengaged to allow an alteration of the angular setting of the drum 16. The shaft 38 revolves twenty-four times per machine cycle. Loosely mounted on the shaft 38 is the cam drum 16 for operating the rear cross slide of the machine. A figure-ofeight type cam groove is designed to give one forward feed or one rearward feed of the slide for a complete revolution of the cam. A control disc 40 having twenty-four peripheral slots is rotated by an eccentric driving pin 41 carried at the end of the shaft 38 and so completes one resolution for one revolution of the drum 14. The disc is formed with a series of equally-spaced holes 43 into which may be inserted cam dogs 44. With the parts in the. positions shown in Fig. 2, a further rotational movement of the-disc 40 causes the dog 44 to move a pin 45 carried by a bell-crank lever 46, 47, 48 and so retract a catch 49 against the action of a spring 50. An inclined tooth 51 at the end of the catch is moved out of engagement with a similar tooth 52 formed at the end of a plunger 53 which is moved by a spring 54 into a slot 56 in a disc 57 driven by the shaft 38. The cam 16 is thus driven by the shaft 38. As the cam completes a revolution, the wedge teeth 51, 52 come into contact again and the plunger is retracted to uncouple the cam from the shaft and the cam will remain at rest until a second dog 44 actuates the bell-crank lever and catch 49. If several movements of the slide are required for one machine cycle, further dogs may be fitted to the control disc 40.

In an evaporator of the type wherein the liquid being evaporated is spread as a downflowing-film on the inside surface of an externally-heated tube 40 by the rotation blades 52 which are pivoted on pins 51, the liquid reaching the lower end of tube 40 flows on to annular shoulder 48 where it is dammed-up and the surface 53 of the dammed-up liquid has an approximately paraboloidal section. This damming-up inhibits the flow of liquid to the outlet 44, whereby the residence time of the liquid in the evaporator is extended, and it is ensured that a uniform liquid-film is maintained on the inner wall of the main section of the tube. Two or more annular shoulders for deflecting the liquid may be provided in an evaporator-tube of stepwise diminishing cross-section. An evaporator tube arranged horizontally is also described.
