Title: Apparatus for the automatic control of the speed of the feed movement of a grinding machine wheel
IPC: B24B49/04
Filed: 1956-02-13
Abstract: 786,611. Grinding. MOVOMATIC SOC. ANON. Feb. 13, 1956 [Feb. 16, 1955], No. 4397/56. Class 60. The rate of feed of a grinding wheel is automatically controlled by the use of a measuring device which continuously measures the difference between the actual diameter of the workpiece and its desired final dimension and continuously controls the rate of the feed in accordance with the value so measured. The invention is applied to a machine in which the grinding wheel head S, Fig. 1, is moved to and from the workpiece W by a cylinder-andpiston device K, the flow of fluid to and from opposite ends of which is controlled by two solenoid-operated valves V1, V2. The measuring device consists of two spring-connected levers h1, h2, Fig. 2, provided with feelers t1, t2 engaging opposite points of the workpiece, the lever h1 being arranged to operate through toothed gearing z1, z2 and an arm x the slider b of a potentiometer p mounted on the lever h1. The potentiometer and slider, together with a generator g, are arranged in a circuit through contacts a1, a3 with the solenoid M1 actuating the valve V providing for the feed of the head S ; by appropriate design of the potentiometer the difference between the actual diameter and desired finished diameter of the workpiece is arranged to produce a linearly-related current in the circuit which corrrespondingly controls the valve V1 and rate of feed of the head S. Also mounted on the lever h2 is a switch k which is connected to one side of the generator g and through the solenoid M2 to the other side of the generator ; this switch is closed by the arm x when the workpiece reaches its finished diameter, at which stage the solenoid M1 is de-energized and the solenoid M2 energized so as to actuate the valve V2 for the rapid return of the head S. The initial rate of feed of the head S is set by a valve Vain the supply to the valve VI and a by-pass around the valve V1 controlled by a valve Ve permits a slight flow of fluid when the valve V is closed. The feeler t1 is adjustable by a screw e in the lever h1.

The lower shell 11 is transversely curved to provide an outer convex heat-emissive surface and the upper shell 12 may be flat or curved. In one embodiment, as shown in Fig. 3, the lower shell 11 has straight side portions 40 and the flat upper shell 12 has pressed strengthening indentations 18. The shell portions are joined by self-tapping screws and the joint is sealed with a high temperature jointing compound (Figs. 5-7, not shown). A series of vanes 16 may be mounted in the upper part of the duct to direct the hot air stream on to the radiant surface of the shell 11. External convection currents are opposed by side plates 22 and an insulating blanket 24 is laid over the upper shell 12. The duct is supported at intervals by hangers 21. In alternative embodiments the upper shell is curved to give the duct a lenticular cross-section (Fig. 10, not shown). In the heating system, Fig. 1, a heater 13 supplies hot air to the duct circuit. The radiant emissive power of the flow half of the duct is depressed by installing a deeper duct than at the return half of the circuit which has vanes 16 to enhance its emissive power.

Water withdrawn from the web or board is passed back to a storage tank 7 or to a pump 6 for re-circulation. The belt 11 may be cleaned by a rotating beater-roll 25 and sprays 26, 27. Keratin &c. may be included in the fibrous suspension to retard setting of the plaster &c. The products have low thermal conductivity, and are sound-insulating and fire-resistant. They may be impregnated with dyestuffs and may be covered or inset with synthetic plastics, metal foils or veneers, which may cover the surface only partly or in patterns. A smooth surface may be obtained, e.g. by winding the board on tissue paper which may be subsequently discarded, or on synthetic resin foil.
