Title: Improvements in or relating to Thermostats.
Inventor: HEARSON CHARLES EDWARD
IPC: G05D23/02
Filed: 1918-09-16
Abstract: 125,316. Hearson, C. E. Sept. 16, 1918. Thermostats.-The units of expanding-rod thermostats of the type operated by the difference in expansion under heat between adjacent members of different material, are made more compact by employing a series of rods side by side of alternate large and small coefficients of expansion and connected in series so that the movement of the final rod is the sum of the differences in expansion of each pair of elements. In the example shown in Fig. 1, circular-section rods are used, the materials being alternately brass and nickelsteel. The central rod b is of steel and is connected at the lower end to the end of a brass rod a, the upper end of which is joined to an adjacent steel rod b<1>, the " series " connexion being carried on through the rest of the six surrounding rods a<1>, a<2> of brass and b<2>, b<3> of steel. The upper end of the steel rod b and the lower end of the steel rod b<3> are free and extend beyond the group. The connexion between the rods is preferably made as shown in Fig. 5, in which a shouldered part of the nickel-steel rod b<2> passes through a hole in the bent over end of the brass rod a<1> and is riveted over. The rods are kept together by clips c, c<1> of strip metal. The whole may be enclosed in a brass tube d depending into the room or chamber, the temperature of which it is desired should govern the operation of the thermostat. The tube then forms one element. In a rise of temperature, the operating rod e falls by an amount equal to the cumulative differences of expansion between four pairs of dissimilar materials. The thermostat may be arranged to work upwards on a rise in temperature. Specifications 102,538 and 121,097 are referred to.

Abstract: 312,236. Wolnik, M. May 22, 1928, [Convention date]. Valves, arrangement of; air vessels. - In coin-freed apparatus for vending liquids, such as petrol, liquid in passed by means of the manually operated pump 16 from a storage tank 15 through pipe 41 and valve 19 to a measuring vessel 17 for delivery by a hose 14. The valve 19 consists of a cylinder provided with an eccentric passage 43 normally out of register with the pipes 41 and 47. After insertion of coins in the shoot 57 the cylinder can be rotated to open the valve by a handle 13. The pump 16 has a displacement valve 33 whose spindle 32 passes through the piston 30 and is packed by an adjustable stuffing box 31 which serves to carry the valve 33 along with the piston unless said valve is prevented from moving. On the upward movement of the piston 30 the valve 33 rises, until it reaches the discharge port 40. Further movement of this valve is prevented by the spindle 32 striking the top of the cylinder 34. The piston however continues to rise thereby filling the cylinder and the air trapped in the pocket 36 is compressed. When the piston descends the valve 33 is carried to its lowermost position in which it closes the inlet 38 and displaces liquid the whole of which is then discharged by the air pressure to the container 17. This container 17 is suspended from a balanced lever 55. When the required amount of liquid has entered, the container descends and the float 79 is then opened by stop 83 to allow liquid to pass to the outer tank 78 and delivery pipe 14. The pressure of the liquid keeps the float from reseating until the contents have been discharged. The arm 53 on valve 19 lies in the path of lever 55 and is rotated by this lever to close the valve 19 when the lever descends with the container.
