No. 28002.—9th August, 1909.—GEORGE ALFRED JULIUS, of Ocean Street, Woollahra, near Sydney, New South Wales, Australia, Engineer. Apparatus for printing tickets or checks of different denominations, and for registering and totalling numbers and indicating the totals.

[NOTE.—This is an application under the International and Intercolonial Arrangements, the date given being the official date of the application in Australia.]

Extract from Specification.—This invention consists in pedal-actuated mechanical apparatus for printing tickets or checks of different denominations, for registering and totalling separately the issues of the several denominations of such tickets or checks, and the grand total of all issues thereof, for registering and totalling separately and in the aggregate numbers and groups of numbers and the grand total thereof and indicating such totals, and for integrating a plurality of groups of totals of equal values, and registering and indicating the grand totals of such groups and of all the numbers contained in the sum of all such groups. The said apparatus is of that kind in which every ticket or check marking certifying element or number-registering element is a unit in a group of such elements, which together make up a section of a complete machine, or a complete machine, the number of separate units used depending in each case on the number of different classes or values of tickets or checks required to be printed or marked; and it embodies also mechanism for the grouping of two or more separate sets of such elements, and for the separate integration and computation and indication of the totals of all corresponding elements in the several sets.

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