eminently applicable for use in electric traction, and then the casing may be made of such a character as to exclude from the mechanism which it contains water, earth, or other extraneous matter, and may be constructed, when used for electrical traction, to be bolted to one of the track-rails. The mechanism comprises means for automatically returning the operating-arm which is fixed upon the spindle, and consequently the spindle, to a normal position of rest after it has received a partial rotation in either direction, as well as to limit and define the extent of such angular movements of the spindle and operating-arm, and the present invention utilises the motions of that mechanism which limits the angular movements of the arm and which returns it to its normal position to actuate the novel devices hereafter described by which the rotary part of the switch directly receives its angular movement.

(5.) In combination with the bowl of a centrifugal liquid-separator, of a division-contrivance arranged within the liquid-space of the bowl, and consisting of a series or row of upright division-blades which intersect the radial lines of the bowl and links which connect the upright edges of adjacent blades at one side of the series or row of blades, substantially as set forth.

No. 16740.—4th August, 1903.—GEORGE GARIBALDI TURRI, of Salisbury Building, Queen Street, Melbourne, Victoria, Patent Agent (nominee of John McKay, of 3, Victoria Road, Woodstock, Cape Town, Cape Colony, South Africa, Storeman). Improvements in football-valves and connected parts.

Claims.—(1.) In combination, a casing having within it an inflation-valve (secured on its seat by a removable nut) and having an internally and externally screw-threaded stem, and at its outer end a flange having a convex outer surface, a ring fitting non-revolubly on said stem, and means to secure airtight the football-bladder between the inner surface of said flange and the said ring, as set forth. (2.) In combination, a casing having within it an inflation-valve (secured on its seat by a removable nut) and having an internally and externally screw-threaded stem, and at its outer end a flange having a convex outer surface, means for securing the outer side of the football-bladder airtight to the inner side of said flange, a cap having an externally screw-threaded hollow shank engaging the said internal thread, and a flange convex externally and concave internally to compress the leather football-cover upon the convex surface of the flange of the aforesaid casing. (3.) The combination with the valve casing—having the inflation-valve, inner removable nut, rubber disc, outer nut, non-revolute ring, and flange—of the screw cap—having the externally threaded hollow shank and downwardly curving flange—and the bladder and leather cover having the apertures and countersinking described, whereby the parts are secured in position as indicated.
