摘要： 173,348. Rogers, F. H., (Matthews & Bro.., Inc., W. N.). Oct. 9, 1920. Piston valves. - The supply of air and liquid to a spraying nozzle are controlled by means of a valve 9 working in a differential bore and provided with annuli 9 , 9 . An independent control of the two fluids is obtained by means of valves 33, 34 having knurled heads screwed into tapped holes in the ducts 7a, 7 .

摘要： 173,349. Rogers, F. H., (Matthews & Bro., Inc., W. N.). Oct. 9, 1920. Piston valves. - An atomizer, more particularly for spraying paint, insecticides, &c., comprises a casting 1 and a nozzle fed by two ducts 1 , 1 formed in the casting. Means such as screw valves 13, 14 engaging in threaded openings in the casting are provided for independently regulating the flow of fluid through the ducts 1 , 1 and an operating valve 3 is provided for controlling the passage through both ducts. The valve 3 comprises a piston having annular grooves 3 , 3 , a spring 4, and a press-button 5.

摘要： 117,223. Warner, W. J., and Matthews & Bro., W. N. Jan. 3, 1918. Mixing-valves.-Apparatus for heating water by direct contact with steam, for use in bath-rooms, laundries, &c., comprises a mixing chamber 10, steam and water inlet valves 55, 20 on opposite sides of the mixing-chamber, and a screwthreaded spindle 30 for operating the valves by the engagement of a conical enlargement 32 on the spindle with a projection 22 on the water inlet valve, and by direct engagement with the spindle 57 of the steam-inlet valve. The mixing- chamber consists of perforated plates 42, 35 carrying perforated ring-shaped partitions 39, 45, which form annular passages 46, 47 around the central mixing compartment 41. The water is discharged from the outer annular passage into a spout 11. The valves slide in perforated sleeves 18, and are pressed upon their seats by springs, and by the pressure in the steam and water pipes. The water inlet is opened before the steam inlet valve, so that cold water is discharged during the first few turns of the spindle 30.

摘要： 117,221. Warner, W. J., and Matthews & Bro., W. N. Jan. 3, 1918. Mixing-valves. - In a direct-contact water heater for use in bath-rooms, laundries, &c., the steam and water enter the mixing-chamber through oppositely-disposed valves 22, 23, which are operated simultaneously by a rotatable spindle 41. The mixing-chamber contains a removable perforated cylinder 31 divided transversely by a perforated partition 33, through which the mixture passes on its way to the outlet pipe 39. The annular space between the cylinder and the casing 10 is divided by a circumferential rib 35. Longitudinal ribs 10 in the front of the annular space prevent the direct contact of steam and water before passing through the perforations in the cylinder. The inlet valves are operated by the rotation of cams 42, 43 bearing against the valve spindles, the cams being so shaped that, while the water valve opens directly, the steam valve is not opened until the operating handle has been moved over, say, a half its length of travel. The valves slide in perforated sleeves 19 and are pressed against their seats by springs and by the pressures of the steam and water) entering through the pipes 29, 30, respectively.

摘要： 117,222. Warner, W. J., and Matthews & Bro., W. N. Jan. 3, 1918. Heating water. - In apparatus for heating water by direct contact with steam, for use in bath-rooms, laundries, &c., the steam and water pipes 12 are connected to a chamber 21 containing perforated plates 27, 31 having projecting perforated rings 29, 34 forming a central mixing chamber 38 and two annular mixing chambers 39, 40. The perforations in one ring are arranged opposite to those in the other ring, so that the steam and water must pass around the annular chamber 39 before entering the outer chamber 40, on which the outlet spout 24 is fitted. Adjustable plugs 14 are provided in the pipes 12 in front of the screw-down valves 10, 11.
