PNEUMATIC DOOR RING RIVETER The type of pneumatic riveter shown in the illustration hasbeen developed especially for driving boiler door ring main frame is a Steel casting to which are secured thecylinder, the stake- and the operating mechanism. It is de-signed for swinging suspension and the arrangement is sim-ple and compact. This machine is built by the Vulcan Engineering SalesCompany, Chicago, and employs the Hanna operatingmechanism. This provides a gradually increasing pressure. Hanna Door Ring Riveter through the greater part of the stroke until the desired maxi-mum is readied, after which the pressure remains uniformuntil the completion of the stroke. The toggle mechanism,the plunger and the piston head are steel castings. Highcarbon steel is used for the piston rod. die screw, lower dieholder and dies. Liquid for Hydraulic Jacks.—A hydraulic jack shouldbe filled with alcohol 1 part, water 2 parts, with a tablespoon-ful of sperm oil added. It should never be filled with water,kerosene or wood alcohol. Water is liable to freeze or rustthe jack; kerosene destroys the packing; wood alcohol de-stroys packing and corrodes the metal.—Engineering andMining Journal. CYCLOIDAL WHIR METER A water meter of the weir type has recentl) been developedl.\ the Kennicott Company. Chicago Heights, 111., in whichthe rate of flow varies directly as the head of water in theweir chamber. The arrangement of the device is shown inthe drawing. Oth
