25,313. Siemens Bros. & Co., [Siemens & Halske Actiengesellschaft]. Nov. 30. Annular-chamber type.-Air is drawn in at the inlet g and expelled at the outlets k by a cylindrical piston d embracing and actuated by an eccentric cylinder c on the shaft b. The piston has an extension e with a projection h pressed by a spring l against the side of the extension f of the casing a. Lubricant from a cup p passes through channels m, which may contain loose rods, to the interior of the piston d, escaping at the sides to the exterior thereof, where it acts as packing, and being expelled through the outlets k falls into channels n, which convey it to the shaft b and thence to the interior of the casing a.
