No. 22482.—10th March, 1906.—PETER BURD JAGGER, of 47 Warwick Road, Maida Vale, London, England, Engineer. A process of and means for manufacturing concrete slabs, beams, pipes, and other concrete articles.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) The described process for manufacturing concrete articles by placing the plastic concrete in suitable receptacles on a platform which is caused to vibrate horizontally, and is also subjected to a series of vertical blows. (2.) A process for manufacturing concrete articles by placing the plastic concrete in suitable receptacles on a platform which is subjected both to a horizontal vibratory motion and to a suddenly arrested rocking motion, substantially as described. (3.) In the processes described and claimed in claims 1 and 2 hereof, subjecting the platform to a series of horizontal blows in addition to the vertical blows. (4.) A machine for manufacturing concrete articles in which a table or platform is horizontally reciprocated, and a series of vertical (and, if desired, a series of horizontal) blows are given thereto by imparting a rocking motion thereto to cause the ends of said table or platform to alternately strike (perferably) wooden concussion blocks supported beneath said ends. (5.) A machine for manufacturing concrete articles as described and claimed in claim 4 in which the desired movements are imparted to the platform by supporting the same on a transverse shaft resting on two levers, which levers and also the platform are actuated by eccentrics on a shaft running longitudinally of the machine, substantially as described. (6.) In a machine as described and claimed in claim 5, connecting the eccentrics to the levers or platform by means of elastic and (perferably) adjustable connections, substantially as described. (7.) The use for the described processes and in connection with the described machines of a trolley or support for the moulds containing the plastic concrete, having an independent movement relative to the supporting platform, substantially as described. (8.) A machine for the manufacture of concrete articles, constructed substantially as described, and illustrated in the drawings.

No. 22632.—4th April, 1907.—EWALD GOLTSTEIN, of Cologne on Rhine, Saliering 14, Germany, Engineer. Improvements in means for opening bottle-stoppers.

Claims.—(1.) A means for opening bottle-stoppers in which a disc is pressed by a capsule on the bottle-mouth, and in which the top of the capsule is provided with such a nick or notch or perforation that within it a flap remains which retains its connection with the capsule on one side and which usually lies level with the capsule surface, but when bent up serves as handle for tearing off the capsule, substantially as described and shown. (2.) A means such as described, for opening bottle-stoppers, in which small very easily destroyed bridge pieces are provided between the flap and the surface of the capsule, which prevent the unintentional erection of the flap. (3.) A means such as described, for opening bottle-stoppers, in which auxiliary nicks or notches are provided in addition to the main perforation or nick which forms the flap, which auxiliary perforations are at so small a distance away from the main perforation that the connection is easily torn through, and which extend so far towards the edge of the capsule that after the connection has been torn through it is very easy to destroy the capsule.

No. 22633.—4th April, 1907.—EWALD GOLDSTEIN, of Cologne on Rhine, Saliering 14, Germany, Engineer. An improved bottle-capsule.

Claims.—(1.) A bottle-capsule of thin easily cut sheet metal, provided on its upper surface with a projection which may be cut off with an ordinary knife in order to open the bottle, substantially as described. (2.) In a bottle-capsule such as described, the projection having such a diameter that its edge rests on the bottle-neck in such a way that it is impossible for the projection which is to be cut off to be forced into the bottle-mouth, and so that great resistance is offered to the knife when cutting off the projection, substantially as described. (3.) In a bottle-capsule such as described, the cover of the capsule being provided with such a projection adapted to be cut off, the edge of which partly rests on the bottle-neck, substantially as described. (4.) In a bottle-capsule such as described, the projection being provided with a nick or contracted base with the object of preventing deflection of the knife when cutting off the projection, substantially as described. (5.) In a bottle-capsule such as described, a plate or ring being inserted between the capsule and the bottle, which prevents the projection being forced into the bottle-mouth, substantially as described. (6.) In a bottle-capsule such as described, the projection having (in plan view) an angular form with the object of allowing it to be more easily cut into by means of the corners, substantially as described. (7.) In a bottle-capsule such as described, a strengthening-disc being inserted in the projection and held by its contraction, substantially as described. (8.) In a bottle-capsule such as described, the projection being made annular (round or polygonal), substantially as described. (9.) In a bottle-capsule such as described, the projection being provided on only a part of the capsule-cover, substantially as described.

No. 22734.—24th April, 1907.—WILLIAM BALDWIN, of 21 Falmouth Chambers, 117 Pitt Street, Sydney, New South Wales, Australia, Merchant. A method of waterproofing floors and roofs.

Claims.—(1.) In the formation of waterproof roof and floors, the use of “hot coating,” consisting of a mixture of a heavy consistency of asphalt with a lighter consistency of asphalt in the proportions stated, and for the purpose set forth. (2.) A method of waterproofing floors and roofs consisting in the application of two or more layers of fibrous material or felt saturated with and rendered waterproof by means of asphalt, bitumen, malta, or other similar bodies, consisting principally of hydrocarbons (in some cases coated with a non-oxidizing waterproof material as set forth), secured together and to the concrete or iron foundation by layers of “hot coating,” the overlapping edges of the upper layers being secured together by the application of heat by flame from a blowpipe or similar instrument and pressure, and the whole surface top dressed with a coating of cement and sand floated on, as described and illustrated, and for the purposes set forth. (3.) A method of waterproofing floors and roofs consisting in the application of two or more layers of fibrous material or felt saturated with and rendered waterproof by means of asphalt, bitumen, malta, or other similar bodies, consisting principally of hydrocarbons (in some cases coated with a non-oxidizing waterproof material as set forth), secured together by layers of “hot coating” (the lower layer of fibrous material or felt being secured to a wood foundation by means of nails), the overlapping edges of the upper layer being secured together by the application of heat by flame from a blowpipe or similar instrument and pressure, and the whole surface top dressed with a coating of cement and sand floated on, as described and illustrated, and for the purposes set forth. (4.) In the method of waterproofing floors and roofs as claimed in claims 2 and 3, the combination of the various layers of fibrous material or “felt,” “hot coating,” and top dressing therein claimed with “hot coating” and pea gravel as a means of securing a better adhesion between the top layer of fibrous material or felt and the top dressing, as described, and for the purposes set forth.

No. 22743.—24th April, 1907.—HARRY ORMISTON ORMISTON, of Brighton, French Street, Kogarah, near Sydney, New South Wales, Australia, Assayer; and WILLIAM DAVID MARTIN, of Mokoia, Alma Street, Ashfield, near Sydney aforesaid, Mechanical Engineer. An automatic tell-tale apparatus to indicate when certain parts of running machinery are worn down to a predetermined point.

Claims.—(1.) In running machinery, a warning or tell-tale appliance consisting of a lower ebonite block with projecting metallic contact points, an upper ebonite block with projecting metallic contact points, a spring to keep the upper and lower contact points apart, and an electric-bell circuit which shall be closed when the contact points on the two blocks touch, for the purpose of warning the attendant, as set forth. (2.) In running machinery, a warning or tell-tale appliance consisting of a lower ebonite block with projecting metallic contact points and a spring, an upper ebonite block with pro.
