Abstract
251,721. Smith, M. Feb. 25, 1925. Actuating pumps by hand and foot power; portable hand pumps.-The hollow piston-rod 8 of a tyre pump leading to a pressure-gauge 15 has in it a plug 13 provided with a hole of a diameter between .001 and .004 inches tu prevent violent fluctuations of the gauge pointer.
