[No. 78

Extract from Specification.—This invention relates to improvements in machines for cutting metal. In machines of this kind at present in use the cutting-surfaces are arranged somewhat in the form of a pair of scissors, which twist or bend the material being cut off and necessitate its being straightened out when the cutting operations are completed. They have also the defect that the machines are constructed in such a way that the working-parts are above the level of the shear-blades, and so often come in the way of the material being cut up. In order to obviate this defect I have devised a special form of shears in which, instead of only two cutting-edges, a blade works in between two other cutting-edges, which has the effect of shearing out strips of the material being cut, the arrangement I adopt being equivalent to giving a shearing-stroke to the moving blade of a punching-machine. This blade is mounted so as to enable the material being worked to pass on either side of it, which enables any length of cut to be made.

No. 16907.—1st September, 1903.—HENRY DROUTLEGE, of Vermont Street, Grey Lynn, Auckland, New Zealand, Engineer. An improved registering-number-recording machine.

Extract from Specification.—It consists of a series of individual registering-wheels, each set being the same as the other sets and worked in the same way, and all connected to a horizontal rod which works another and distinct set of wheels, which give the grand total of the other. The series of individual sets of wheels and distinct set of grand-total wheels are all contained within a suitable frame, with openings in its front so that the numbers adjusted to each set of wheels will show therethrough as they are caused to rotate, each individual set for itself and the grand total for them all.

No. 16909.—4th September, 1903.—THE WOLSELEY SHEEP-SHEARING MACHINE COMPANY, LIMITED, of Sydney Works, Alma Street, Birmingham, England, Manufacturers, and HERBERT AUSTIN, of St. Anne’s, Sutton Road, Erdington, Warwick, England, Engineer. Novel or improved flexible joint and casing for use with the vertical flexible shaft which transmits power to a machine for cutting or shearing hair or wool.

Extract from Specification.—This invention has for its object to substitute for the flexible sleeve a rigid sleeve, having a joint through the medium of which it is connected with the bracket aforesaid, which will insure sufficient elastic resistance, against an outward movement of the lower end of the vertical shaft, to counteract, or largely so, the swing or momentum of the sleeve and shaft and thus obviate or minimise the inconvenience above referred to. Broadly described, the joint aforesaid, which forms an important feature of this invention, comprises an upper portion, which is adapted to be securely fixed to the bracket aforesaid, a lower portion, which is capable of being moved to bring its axis angle-wise with that of the upper portion, and a spring against the elastic force of which the lower portion of the joint is moved in relation to the upper portion; and the rigid sleeve is rigid with the lower portion of the joint.

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