No. 11491.—29th March, 1899.—CLEMENS BARON VON BECHTOLSHEIM, of 27, Maria Theresa Strasse, Munich, Germany. Improvements in milking apparatus.

Claims.—(1.) A milking apparatus characterized by a cylinder operated pneumatically, hydraulically, or by vacuum, and provided with an automatic reversing valve arrangement, and located between the teats, being suspended thereon by milking-devices, which are also operated pneumatically or hydraulically, and are moved up and down so as to exert at periodical intervals a pull on the teats and a pressure on the udder, with the object of enabling the milking-machine to be worked with a constant pressure in the operating-pipe, and of requiring no further support for the apparatus than that afforded by the milking-devices themselves, substantially as described. (2.) In a milking apparatus such as hereinbefore described, the arrangement of two cups, diametrically opposite one another, and attached to a piston, and two others attached to a cylinder, so that the respective pairs mutually alter their positions as regards height in such a way that the for-the-time-being-descending pair, squeezing the teats, milk the same out and exert a pull thereon, whilst the rising pair of cups are opened to allow the teats to enter therein, and exert a pressure against the udder substantially as described. (3.) In a milking apparatus such as described, the arrangement of valves or devices for producing the alteration in the conditions of pressure in the cups in such a way that on a change of movement all four cups simultaneously squeeze the teats, in order to prevent at this moment the apparatus dropping off the cow, substantially as described.

(2.) In a potato-digger, the combination with an inclined curved riddle of a screw-elevator within the same, having an incurved rounded entering-edge, and at its discharge end bevel-gear operated by sprocket-and-chain mechanism, whereby the said screw will, by the turning of the traction-wheels of the machine, be revolved so as to carry potatoes or the like up the riddle at a comparatively rapid rate, substantially as and for the purposes set forth. (3.) In a potato-digger, the combination with a riddle and elevating-screw, gear for rotating said screw by the forward motion of the machine, a clutch for connecting and disconnecting said gear, a roller (wheel or wheels) in front of said riddle, connections between said roller (wheel or wheels), and riddle for adjusting the cutting-depth of the latter, and a lever or winch to lift the front of the machine off the ground, all substantially as and for the purposes set forth. (4.) In a potato-digger having an inclined curved riddle having an elevating-screw, having an incurved rounded entering-edge, said screw being adapted to push potatoes up the said riddle, and dirt and haulms through the bars thereof, the combination therewith of a box or potato-receptacle S, having a door T with pivot T¹, and connections U¹ to handle U, whereby the door can be opened and the box emptied at will, and whereby the door of said box will close automatically when the lever or handle U is released, substantially as set forth.

No. 11498.—30th March, 1899.—HUMPHREY ARTHUR SALTMARSHE, of 21, Queensland Deposit Bank Chambers, Adelaide Street, Brisbane, Queensland, Mine-owner. River-bed mining apparatus.

Claims—(1.) In a river-bed mining apparatus or principle, a sloping tunnel passing beneath the river-bed, uptakes or stopes connecting said tunnel with the bed of the stream, and grizzlies or grate-bars arranged over the uptakes so that the heavier bodies, such as precious metals, will pass through the grizzlies to the tunnel as specified. (2.) In river-bed mining, a tunnel passed beneath the bed of the stream to be operated upon, stopes connecting with the said tunnel and the bed of the stream, a grizzly covering the top of the openings or stopes approximately on a level plane with the river-bed, and one or more other grates or grizzlies arranged in the framework of the stopes between the bed of the stream and the tunnel, and means for conveying the materials passed through the grizzlies to the surface of the ground at some point above the flood-mark of the stream, substantially as specified. (3.) In river-bed or placer-mining, a tunnel passing beneath the stream to be operated upon, and means for connecting with the bed of the stream, as specified; a semicircular groove, 17, arranged in the tunnel; a worm-conveyer, 18, arranged to turn in the groove, and means for operating said conveyer from the surface of the ground, as and for the purposes specified. (4.) In an apparatus or system of the kind and for the purposes described, a tunnel arranged beneath the bed of a stream to be operated upon, means for communicating with the bed of the stream, a vertical shaft connecting the outer end of the tunnel with the surface of the ground at a point above high water, and means for sealing or closing the tunnel off from the shaft by a sliding-door, all substantially as specified. (5.) In an apparatus for deep river-bed mining, a shaft and tunnel having stopes or openings transversely across the bed of a stream, in combination with a self-adjusting hoisting-bucket, 10, for hoisting the auriferous sands and gravel to the surface, as and for the purposes specified.
