No. 22474. — 28th February, 1907. — WALTER GEORGE CROSTHWAITE, of York Street Mills, York Street, Leeds, York, England, Woollen-manufacturer. Improvements in firebars for furnaces.

———

Claims.—(1.) Constructing a furnace-grate of a series of transverse bars which when together in position form tubes or passages through which air or air and steam may be forced and distributed in fan-shaped jets uniformly through the fuel, substantially as described and illustrated. (2.) Constructing a furnace-grate substantially as claimed in the last preceding claim in combination with air-passages formed in and by the bars when put together, which passages are for the purpose of conveying heated air either with forced or natural draught to the back of the bridge for the purpose of obtaining more perfect combustion, substantially as described and illustrated. (3.) The form of the furnace firebar described and particularly illustrated in perspective in Figs. 8 and 9 and section 10, and possessing the following features: Tubular openings E with fantail openings b¹ to the grate which are upwardly tapered and narrowed as shown at L, flanges e, annular recesses e¹ and tubular openings I, all of which openings are capable when several bars are placed together of performing the functions described.

No. 22514.—6th March, 1907.—AKTIEBOLAGET SEPARATOR, a corporation existing under the laws of Sweden, and having its place of business at 8 Fleminggatan, Stockholm, Sweden, Manufacturers (assignees of Birger Ljungstrom and Fredrik Ljungstrom, both of Fleminggatan 8, Stockholm, Sweden, Engineers). Improvements in operating-devices for milking-machines.

———

Claims.—(1.) In operating-devices for milking-machines, consisting of a pump connected with the milking-organs, the improvement that said pump communicates with a liquid-receptacle by means of a suction and a force valve. (2.) In such operating-devices as claimed in claim 1, the improvement that the pump is located in the liquid-receptacle. (3.) In such operating-devices as claimed in claims 1 or 2, the improvement that the force-valve of the pump is pressed against its seat by means of a spring or weight. (4.) In such operating-devices as claimed in claim 3, the improvement that the pressure of the spring or weight is controllable from outside the pump. (5.) A constructional form of the device claimed in claim 4, characterized thereby that the spring pressing against the force-valve abuts with its other end against a disc, which by means of a lever and a screw engaging the end of the lever and projecting outside the pump can be raised or lowered in order that the pressure on the force-valve may be regulated by turning the screw. (6.) In such operating-devices as claimed in claims 1 or 2, the improvement that the connection between the pump and the milking-organs is effected by means of a conduit having a coupling whose halves will loosen from each other when there is a draft in the conduit exceeding a fixed one.

No. 22535.—13th March, 1907.—WILLIAM HENRY BLACKHAM, of 59-61 King Street, Melbourne, Victoria, Australia, Merchant (assignee of William John Teese, of 80 William Street, Balaclava, Victoria, Australia, Engineer). Improvements in and connected with vacuum and pressure apparatus for milking cows.

———

Claims.—(1.) In apparatus for milking cows, a teat-cup the walls of which in section converge upwardly, the top of said teat-cup folding over an annular metallic passage-way open at the bottom and having flanges protruding downwardly, the said flanges passing inside the top of a cylindrical casing, at the bottom of which casing is an outward bead, a bottom piece secured underneath the said teat-cup by a milk-discharge tube having a flange at its top and a nut at its bottom, expansion rings or corrugations around said bottom piece, said bottom piece having a pressure air-inlet tube therein, the top of said bottom piece passing outside the outward bead and inside a locking-ring and then folding downwardly, all as and for the purposes described, or as illustrated in the drawings. (2.) In apparatus for milking cows, and in combination, a reciprocating pump in one end of which air is compressed and passes through a compressed-air pipe, one or more relief-valves upon said compressed-air pipe, said compressed-air pipe communicating with an annular space around a teat-cup of the character described, and in the other end of which pump vacuum is formed, said vacuum by a vacuum-pipe being communicated to the interior of a teat-cup of the character described, all as and for the purposes described, or as illustrated in the drawings.

Claims.—(1.) In the apparatus used for milking cows, a reciprocating pump in one end of which a vacuum is formed, which vacuum is communicated to a milk and vacuum reservoir, and to a milk and vacuum pipe-line having a vacuum-regulating valve thereon, in the other end of which reciprocating pump compressed air and partial vacuum are formed, an air-inlet valve to said pump, also a relief valve upon said pump or upon a compressed-air and vacuum pipe-line leading from said pump, said air-inlet valve and relief valve being operated by tappets, a pressure-regulating valve upon said compressed-air and vacuum pipe-line, all as and for the purposes described, or as illustrated in the drawings. (2.) In apparatus used for milking cows, a milk and vacuum pipe communicating with a milk and vacuum reservoir, a milk and vacuum pipe-line having a vacuum-regulating valve thereon, a cock upon said milk and vacuum pipe-line communicating with an intermediate pipe having a window cut therein inside which is a glass tube, said intermediate pipe communicating with an inner pipe, said inner pipe communicating with an internal flexible milk and vacuum pipe, in combination with a compressed-air and vacuum pipe-line, a pressure-regulating valve thereon, also a cock communicating with an intermediate pipe, an outer pipe below said intermediate pipe communicating with an external flexible compressed-air and vacuum pipe, all as and for the purposes described, or as illustrated in the drawings. (3.) In apparatus used for milking cows, an external flexible compressed-air and vacuum pipe the upper end of which is attached to an outer pipe and the lower end to an external compressed-air and vacuum udder-pipe, branches leading from the said udder-pipe, flexible tubular connections on said branches, each connection leading to a compressed-air and vacuum tube the upper end of which is attached to a piston beneath a teat-cup, in combination with an internal flexible milk and vacuum pipe the upper end of which is attached to an inner pipe and the lower end of which is attached to an internal milk and vacuum udder-pipe, the end of said internal milk and vacuum udder-pipe having a removable inspection and cleansing plug therein, an annular plug ring between the ends of said inner and outer udder-pipes, branches passing through the external compressed-air and vacuum udder-pipe and into the internal milk and vacuum udder-pipe, flexible connections attached to said branches, each said connection being attached to a milk-discharge tube the upper end of which is attached to the bottom of a teat-cup, all as and for the purposes described, or as illustrated in the drawings.
