PROVISIONAL SPECIFICATION.
Apparatus for Calculating Employees Wages.
I, HENRY HAYES Builder Mulgrove Street Limerick do hereby declare the nature
of this invention to be as follows:-
-
A cylindrically shaped drum is inclosed in an outer similarly shaped case.
The latter has a narrow opening or slot extending from end to end. The inner
drum is made to rotate by means of an axle passing through its centre and through
holes in ends of outer case a handle being fixed on one end of axle. There are
certain figures denoting amounts of cash suitably arranged on surface of inner drum.
Close to and parallel with slot on the outer case is a column of figures denoting
days and fractional parts of days. Any desired column of figures on inner drum
can be brought under the slot and on it opposite any figure on the days column
will be shown the figures denoting the amount of cash for that time worked.

COMPLETE SPECIFICATION.
Apparatus for Calculating Employees Wages.
I, HENRY HAYES, of Mulgrove Street, Limerick, Ireland, Builder do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention has reference to a new or improved apparatus for simplifying and
facilitating the calculation of employees wages by mechanical means.
The construction and operation of the invention will be readily understood on
reference to the accompanying Drawings in which Fig. 1 represents a side view of
the apparatus complete, showing the slot hereinafter more fully described; and Fig. 2
an end view of same partly in section.
a
A, is an outer cylinder, or drum provided with a narrow opening or slot b,
extending from end to end, in which is placed a strip of glass c. Inside this glass is
arranged a narrow slip of cardboard d, or other suitable substance bearing
column of figures denoting days, and fractions of days. Within this outer cylinder,
or drum an inner cylinder or drum B, is mounted so as to be capable of rotating
on the spindle e, and is clothed round its circumference with a sheet of paper, or card
board divided horizontally and vertically into compartments the vertical columns
being inscribed with certain cash figures, an example of which appears in the column
exposed to view in the opening or slot b.
The inner drum is rotated by means of the milled knob f, and friction between
the two cylinders or drums is provided for by a suitable flat spring which is fixed to
the inner surface of the outer drum and impinges against the inner drum, holding
the same steadily in position while any figures are being read-The projections 9, 9,
serve as legs for the apparatus when lying on its side to enable the calculations to be
conveniently read off.
The action of the apparatus is briefly as follows
When it is desired to ascertain the amount of wages due to an employee for any
specific time within the range of the column d, and assuming his rate of wages to
be, say 5/- per day, the inner drum is rotated until the column bearing the 5/- per
day calculation is exposed, when on looking down the fixed slip for the time specified,
the amount of wages payable will be found in the compartment on the fixed slip
opposite.

page_text: Having now particularly described and ascertained the nature of my said- inven-
tion and in what manner the same is to be performed 1 declare that, what 1
claim is
1st. In the 'process' of calculating wages the combination of an outer and inner
cylinder or drum (the latter being clothed with a horizontally, and vertically divided,
and figured sheet of paper) arranged and operating in the manner substantially as
herein described.
2nd. The method of calculating wages by mechanical means in the manner substan-
tially as herein specified and set forth.
