No. 22880.—20th May, 1907.—SAMUEL THOMAS BEATTIE, of 101 Devonshire Street, Sydney, New South Wales, Australia, Tobacconist, and WILLIAM JOHN CHAPMAN, of 388 Riley Street, Sydney aforesaid, Bookmaker. Improved method of marking race-competitors.

Claims.—(1.) The method of indicating numbers by colours which consists in assigning a particular field-colour to each digit from 1 to 10 and distinguishing each succeeding decade of digits by hoops, stripes, or other marks in white or a colour other than the field colours. (2.) The method of indicating numbers by colours which consists in assigning to each digit from 1 to 10 a particular field-colour in alphabetical name sequence, and distinguishing the several decades of digits by superadding to the field-colours distinctive markings in white or in a colour other than said field-colours. (3.) The method of indicating the numbers borne by competitors which consists in providing them with jackets of distinctive colours corresponding to the digits 1 to 10 according to a prearranged list, and distinguished decade from decade for numbers higher than 10 by white sleeves or by the addition of hoops, stripes, checks, diamonds, or other marks in white or a colour other than one of the colours distinguishing the digits.

No. 22943.—4th June, 1907.—ARTHUR HJALMAR BORGSTRÖM, of Hangö, Grand Duchy of Finland, Merchant. Improvements in the manufacture of butter.

Claims.—(1.) The method of manufacturing sweet or soured butter, either artificial or natural, consisting in working the cream, milk, or the like at such a low temperature that no formation of butter can take place, heating the mass to a temperature that permits the formation of butter, and slowly stirring the mass until the butter has separated sufficiently in the churn-milk or the liquid, substantially as described. (2.) A modification of the method claimed in claim 1, consisting in the butter being gathered after the working and heating, substantially without any stirring operation. (3.) The combination with the method stated in claim 1 or 2 of the method of adding acid just before or during the churning operation, treating the butter in the ordinary manner and permitting the acid to “mature” in the butter, substantially as described.

No. 22947.—5th June, 1907.—THOMAS JAMES MCBRIDE, of Christchurch, New Zealand, Gentleman. Improvements in resilient wheels for vehicles.

Claims.—(1.) In a vehicle-wheel, a flexible tire having constructed longitudinally within it a flexible chain or the like, said tire having openings arranged transversely through it at intervals apart, and bolts extending through such openings and the casement sides for the purpose indicated. (2.) In a vehicle-wheel, the combination of a flexible tire adapted to telescope between the casement sides, with its inner periphery immediately adjoining or bearing upon a pneumatic tube or cushion, substantially as specified. (3.) In a vehicle-wheel, the combination with a channel or casement upon the wheel’s periphery, and a resilient cushion placed therein, of a flexible tire fitting between the sides of the casement and upon the cushion, wearing or draw plates upon the side faces of the tire, openings through such plates and the tire, and bolts passing therethrough and through the sides of the channel, so arranged and constructed as to permit of free radial movement of the tire within the channel, substantially as specified. (4.) In a vehicle-wheel, a flexible rubber tire fitting around the wheel’s periphery, such tire being provided with a flexible chain or the like embedded in or attached to the inner part of the tire, and preferably made continuous, substantially as specified. (5.) In a vehicle-wheel, the combination with a casement or channel upon the wheel’s periphery, and a resilient cushion fitting therein, of a flexible tire fitting between the sides of the channel and upon the cushion, a flexible chain or the like embedded or passing longitudinally within the tire-plates attached to such chain and extending down the side-faces of the tire, a means for retaining the tire within the channel and for allowing of free radial movement therein, substantially as specified. (6.) In a vehicle-wheel, the combination with a casement or channel upon the wheel’s periphery, and a resilient cushion fitting within it, of a flexible tire bearing upon the cushion and fitting between the sides of the channel, wearing or draw plates upon the side faces of the tire, elliptical openings extending transversely through the tire, and the plates and bolts extending through such openings and through the sides of the channel, substantially as and for the purposes specified. (7.) In a vehicle-wheel, a channel or casement surrounding the wheel’s periphery and adapted to receive a resilient tire, such channel being formed of an L-shaped rim, and segment plates fitted thereto, substantially as specified. (8.) The general arrangement, construction, and combination of parts in my improvements in resilient wheels for vehicles, substantially as described and explained, and as illustrated in the drawings, and for the several purposes set forth.

No. 22949.—5th June, 1907.—ALFRED EDWIN DAVIS, of 42 Permanent Buildings, Harrison Street, Johannesburg, Transvaal, Engineer, RICHARD MEYER, of Rand Club, Johannesburg aforesaid, Stockbroker, FRANCIS HASTINGS MEDHURST, temporarily residing at Carlton Hotel, Johannesburg aforesaid, and of Westminster Chambers, 13 Victoria Street, Westminster, London, England, Consulting Engineer, and JOHN EDGAR FERRAR, of Rand Club, Johannesburg, Bank-manager. Improvements in and relating to transporting apparatus for mines.

Extract from Specification.—The invention consists in certain features in the construction of the trucks, cars, or vehicles, and the rails traversed by such vehicles as fully described. The rails are of such construction that they can be moved expeditiously from time to time so as to keep the rail or track at an approximately uniform distance from the broken coal, rock, or mineral, or the working-face, and so allow the vehicles to be run parallel to such face, loaded direct in the stope, and thence allowed to gravitate down the stope to the drive, and, if desired, to the shaft. It is requisite in a transporting apparatus of the nature specified that the trucks, empty or full, shall be able to run freely in either stopes, drives, or shaft, or on the surface; that they shall be capable of running freely in the narrowest of stopes, and of being loaded in such stopes; that when loaded they shall be capable of ascending and descending the steepest of gradients without spilling the contents; that they shall be capable of negotiating sharp points, bends, or curves in the rails, both horizontal and vertical; that they shall be incapable of capsizing or derailing in both stopes and drives; that they shall be capable of carrying loads of half a ton or more; and that they shall be of such a shape as to allow the trucks or vehicles to pass one another freely in drives of ordinary dimensions, and thereby to obviate delays in ramming or transportation of the rock or mineral in long levels. Suitable means must also be provided for easily and quickly discharging the loaded trucks. It is further requisite that the rails constituting the track traversed by the vehicles shall be light, strong, easily handled, capable of being moved easily and expeditiously from place to place; that there shall be freedom from loose parts which might be lost or mislaid; that they shall be stiff vertically so as to carry the necessary load with as few sleepers as possible; that they shall be flexible at the supporting joints; that they shall always be maintained truly vertical, and also allow one length of rail to swing up and down and sideways relative to the next one, so as to follow the inequalities or undulations of an uneven floor, and that if necessary they shall be capable of being bent to any sharp curves without permanent set.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
