PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Checking Workmen's Time.
I, HERMAN JAFFE, of 98 Leman Street, Aldgate, London, E., Gentleman, do
hereby declare the nature of my said invention to be as follows:-
The object of my invention is to effect improvements in an apparatus for
checking workmen's time, for which apparatus Letters Patent dated 23rd October
1889, No. 16,752 have been granted.
My invention relates to the method of inking the type upon the periphery of the
type wheel, and raising the card thereto after inking.
In carrying out my invention, I use a small sliding frame, into which the card
to be printed is placed. The inner end of this frame is fitted with a small inking
roller, the diameter of which is sufficient to ink the type upon the periphery of
the type wheel, without the card being in contact therewith. The sliding frame
is partly supported by means of two slots formed in fixed guide plates and partly
by a movable guide plate having a slot for receiving the same. The inner ends
of the slots are curved upwards, in order that the frame carrying the card may
be thereby raised immediately after the roller has inked the type.
When using the apparatus, the workman inserts his card in the frame and
pushes both forward. This causes the inking roller to ink the type ready for
printing. The card and frame then, on being pushed farther, rise up, by virtue
of the curved slots, (the inking roller being then beyond the type, and out of
contact) the card is thereby pressed against the inked type, whereby the time is
duly printed upon the card. On withdrawing the card the card frame is
immediately lowered away from the type, and is ready for use.
Springs are fitted to the card plate to assist the return of the plate to its
normal position; ready for another indication.
I do not confine myself to the use of one type wheel, as two or more type wheels
of various characters may be used.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Checking Workmen's Time.
I, HERMAN JAFFE, of 98 Leman Street, Aldgate, London E., Gentleman, do
hereby declare the nature of my said invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of my invention is to effect improvements in an apparatus for
checking workmen's time, for which apparatus Letters Patent dated 23rd October
1889, No. 16,752, have been granted.
My invention relates to the method of inking the type upon the periphery of the
type wheel, and raising the card thereto after inking.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a front elevation of the complete apparatus, as usually constructed.
Fig. 2 is a sectional elevation, drawn to a larger scale.

page_text: Fig. 3 is a horizontal section on the line 1-2 of Fig. 2.
The
a is the case fitted with an ordinary clock mechanism, the works of which are
fixed to the back of the case, so as to provide for an elongation of the central
pinion arbor, between the mechanism and the clock face. The arbor revolves once
in an hour and is formed with a toothed pinion (shown by a dotted circle in
Fig. 1). This piniou revolves the toothed wheel c once in 12 hours.
wheel e is mounted on a pin d, preferably with coned bearings e and a set nut f. g is
a ring fixed to the wheel c and revolving therewith. The periphery of this ring is
divided into 12 main divisions, which are subdivided into minutes, the numbers and
divisions (g) being indicated in relief, and preferably moulded in india rubber, as
described in 16,752 is a sliding frame, a portion of which, consisting of a
flattened tube ¹, projects beyond the front of the case, and is guided in a slot in
the fixed plate n. 2 is a fixed frame which supports and guides the sliding
frame is a catch, pivoted to the fixed plate n, and pressed upwards by a coiled
spring m. o is a spiral spring, one end of which is hooked to the plate n, and the
other end to the sliding frame h. is the inking roller, carried in bearings attached
to the sliding frame h. On each side of the fixed frame a groover is provided
for guiding the two ends of a rod (or rollers) s. are slips forming guides to
the cards.
When a card is inserted in the flattened tube h', it first presses down the catch k
and thereby releases the sliding frame h, which is then pressed inwards, carrying
the inking roller t to-the types g¹ and indicator v. The inward movement of the
sliding frame is guided by the rod (or rollers) s in the grooves ¹.
When the
rod (or rollers) arrives at r, the curved groove Linclines the frame.h-upward,
aided-by-springs-The-card-is-thus-carried-upward-so-as-to-be-pressed-against-
the type g and. indicator t, the time being printed upon the card. The card is
then returned to the operator, by the spring o, with the time printed thereon,.
leaving the mechanism ready for a similar operation. The indicator o consists of
a pointer or arrow, placed vertically below the centre line of the wheel'c, so as to
point to the exact time when the card is inserted, the time being printed on the
_card_with_the_hour-and-minute-clearly-indicated..
x is a bell fitted inside the case, which is caused to sound by means of the
hammer w mounted upon a spring y, whenever the sliding frame is pressed
inwards to print a card.
u is a drawer which may be advantageously added to the case, having divisions
formed therein for collecting the tickets relating to each working day.
In some cases I use the drawer as a reservoir of unmarked cards, and fit a lock
to the same, the bolt of which is suspended by means of a cam or equivalent
appliance, on the axle of the wheel c, whereby the drawer may be locked at any
required time.
I do not confine myself to the use of one type wheel, as two or more type
wheels of various characters may be used.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
.
1. In apparatus for checking workmen's time, the improved mechanism' whereby
the operation of inserting and withdrawing the card, causes the same to receive
a printed impression of the time indicated, and leaves the mechanism ready for
a similar operation, substantially as herein before described and illustrated by the
drawings.
+
2. In apparatus for checking workmen's time, the improved combination of
mechanism for guiding and raising the card by means of the sliding frame h and
flattened tube h', guided by the slot in the plate n and the guide slots in the
fixed frame, springs o and p, inking roller t, bar or rollers 8, hammer w, bella,
and locking catch &, severally operating substantially as herein before described
and illustrated by the drawings.

page_text: 3. The improvements in apparatus for checking workmen's time, substantially as
herein before described and illustrated by the drawings.
