    Provisional, Specification. A.D. 1864.—N° 2329. 5 T-4 T. F. Walker's Improvements in Apparatus for the Utilization of Sewage. valves may be weighted to facilitate their closing again after being opened; or in place of two taps and valves a double passage slide combined with a pair of valves may be employed. The improvements also relate to means of applying diaphragms to such 5 pumps in order to their ready removal or replacement when required; for this purpose in some cases we apply the material of which the diaphragm is composed to a metallic rim or frame, formed in parts, connected by hinge joints to admit of its being readily reduced in size, and thereby to facilitate its ready introduction to or removal from the pump, and we apply an edging 10 to it, of india-rubber or other suitable material, to effect a close packing, and we form the part of the pump with grooves to receive the diaphragm, and an opening for its admission closed by a cover. The diaphragm may be of the form of a bottle or other hollow vessel composed of india-rubber or other suitable flexible material capable of expansion and contraction, or opening 15 and closing. Pumping apparatus thus arranged is applicable to raising and forcing other fluids.
