PROVISIONAL SPECIFICATION.
Improvements in Electrically Actuated Time Checking Apparatus.
We, JOSEPH APPLETON and WILLIAM THOMAS BURBEY of 91 Queen
Victoria Street in the City of London, Electrical Engineer do hereby declare the
nature of this invention to be as follows:-
According to our invention we construct an apparatus to be used for checking
the time at which work people enter factories or for checking the time at which a
watchman makes his rounds.
Ordinary workmen's time checks are used which are dropped into a shoot said
shoot being pivoted in such manner as to come over a series of boxes or receptacles
passing from one box to the next at stated intervals. The motion of the pivotted
shoot is preferably obtained by means of a weight or spring, it being retained in
each of its positions by means of a stop or stops which are released electrically
by some part of a clock making contact when the proper time arrives and thus
completing an electric circuit through coils, attracting an armature to which is
connected a stop. As one stop after the other is released the pivotted shoot moves
over the several drawers or receptacles one by one and the workmen dropping
their checks into one or other of said drawers it is known without difficulty or
fear of fraud being perpetrated the time at which they arrived. In order to reset
the time checking apparatus a lever or other suitable mechanism is employed for
pressing down all the armatures at one time and thereby allowing of the backward
travel of pivotted shoot. A dial or other indicating appliance may be attached
either directly or indirectly to the pivotted shoot, so that the workmen may be
able to see and verify the time they enter the factory if necessary.

.COMPLETE SPECIFICATION.
Improvements in Electrically Actuated Time Checking Apparatus.
We JOSEPH APPLETON and WILLIAM THOMAS BURBEY of 91 Queen
Victoria Street in the City of London Electrical Engineers 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 :-
According to our invention we construct an apparatus to be used for checking
the time at which work people enter factories or for checking the time at which a
watchman makes his rounds.
Ordinary workmen's time checks are used which are dropped into a shoot, said
shoot being pivoted in such manner as to come over a series of boxes, receptacles
or compartments and passing from one box or compartment to the next at stated
or predetermined intervals. The motion of the pivoted shoot is preferably obtained
by means of a weight or spring, it being retained in each of its positions by means
of a stop or stops which are released electrically by some part of a clock making
a contact when the proper time arrives and thus completing an electric circuit
through coils and thereby attracting the armature to which the one of the stops
is connected. As one stop after the other is released the pivoted shoot moves
correspondingly one by one over the several drawers or receptacles and as the
workmen drop their checks into one or other of the said drawers it is known
without difficulty or fear of fraud being perpetrated at what time or times they
arrived. The ends of the stops are by preference made with a slanting surface
D077

page_text: so that the shoot when taken hold of can be returned to its starting position,
depressing the stops one by one in passing over them. Or we may employ a lever
or other suitable mechanism for depressing the stops and armatures all at one time
to allow the shoot to be returned. A dial or other indicating appliance may be
attached either directly or indirectly to the pivoted shoot so that the workmen may
be able to see and verify the time at which they enter the factory.
Figure of the accompanying drawings is a front elevation of an apparatus con-
structed according to our invention the apparatus proper being placed in a case
the front of which is shewn removed, the case in or on its upper part containing
the clockwork for driving and which is adapted to our invention. Figure 2 is a
sectional side elevation of same and Figures 3, 4 and 5 detail views.
A is a shoot for the checks to be dropped through from a slot B' in the casing B.
The shoot A works on a pivot A' and is thus capable of moving over a drawer or
box C having a series of four compartments (or any other required number),
and passing thus from one compartment to the next at stated or predetermined
intervals for the purpose of enabling the checks put into the slot B' to drop into
the required compartment. A² is a weight for imparting motion to the shoot which
is, say, from the left to the right. Four stops D are provided which are brass
rods guided in brass bushes in the ebonite plate E the latter being attached by
columns E to the foundation plate E2. The stops or rods D are mounted in the
armatures D1, D2, D3, D4 to four electro magnets F1 F2 F3 F' on the foundation
plate E. From the plan view Figure 5 it will be noticed that the ends of the
rods D have slanting surfaces. G is a clock wheel which turns once in 24 hours.
On its spindle is also fixed a spring G¹ which during the day makes contact
successively say with the four electric contacts H', H², H³, H³, which are mounted
on the ebonite disc H and by wires are connected with the circuit from a galvanic
battery as for instance I in the lower part of the casing B and to the electro-
magnet coils. To a bracket A³ on the shoot A is fixed a spring A for making
contact successively with four knobs L', L2, L3, L4, in the plate E, the said knobs
being connected to wires that lead to the contacts H1, H2, H3, H. The current is
however normally interrupted at the contact make-and-break spring K and the
two contacts K, K' on the hour wheel K. One of these makes contact every half
hour and say for the space of 3 or 4 minutes after the set time so as to give the
workman a little grace.
When contact is made at one of the contacts H H H³
or Hand L L L³ or L the circuit is closed and a current sent through whereby
the armature in question is attracted thus releasing the shoot A which drops upon
the next stop and simultaneously breaks the circuit. The armatures D¹ D³ D³ D*
are by springs M. with nuts M₁ for adjustment of their tension connected to the
foundation plate E².
N is a dial on the shoot marked for instance as shown 7, 7.30, and 2 being the
times corresponding to the four compartments of the box C, for enabling the
workmen to see and verify the time at which they enter the factory. To move
the shoot back to the starting position it is taken hold of and moved from the right
to the left side passing successively over and depressing the stops D the slanting
end surfaces of same permitting them to be readily depressed.
The circuit is as follows. From the positive of battery by wire to the terminal T,
thence by the frame E through the pivot A' and shoot A, the brush on the back
of same, the stud L', one of the electro-magnets E, terminal T' (or T2 T³ or T* as
the case may be all these four terminals being insulated from the frame) thence by
wire to the stud H', brush G¹, insulated sleeve G*, brush G2 and insulated sleeve G³,
thence by wire to the insulated sleeve G, spring K, hour wheel K², through the
frame of the clockwork, stud K³ and by wire to the negative terminal R.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A time checking apparatus consisting essentially of a pivoted circuit making

page_text: and breaking shoot impelled by a weight or spring and arranged for receiving the
checks and depositing them into one or other of a series of compartments or boxes,
the position of the shoot relatively thereto being determined by a corresponding
series of stops which are actuated by the armatures of electro-magnets which are
energized by an electric circuit when a circuit closing device consisting of two
series contacts is actuated by clockwork according to the times required substan-
tially as described and shown.
2. In a time checking apparatus the pivoted shoot A with impelling weight
rod A2 and with circuit making and breaking spring A' in combination with contact
knobs L L L L in an insulating plate E, said knobs being connected to an
electric circuit wherein are also comprised two series contact devices which are
actuated by a clockwork for the purpose of closing the circuit at the desired times,
and with armatures having each a stop rod D which when the circuit is closed and
the required electromagnet is energized by the current is withdrawn and permits
the shoot to be moved into the next position for the checks to be dropped into the
box or compartment corresponding to the time or hour required the circuit being
simultaneously broken by the contact spring A* on the shoot substantially as
described and shown.
3. In a time checking apparatus providing the pivoted shoot A with a dial N for
visible indication of the position of the shoot relatively to the receptacles for the
time checks.
4. The construction of time checking apparatus shown in the drawings.
