An Electric Automatic Time Check.
I, FREDERICK GEORGE MANLEY WETHERFIELD of 1 Gresham Buildings
Guildhall in the City of London Solicitor, do hereby declare the nature of this
invention to be as follows:-
"
"
My invention relates to an "Electric Automatic Time Check " governed
electrically by an ordinary clock. It consists of a small iron box mounted upon a
wooden base in which is a drawer with a lock. This drawer is divided into two
compartments, one for " Early and the other for "Late checks or tickets.
These checks or tickets are dropped by the workmen or employes through a slot
in the top of the box and are in the case of "Early" or "In time tickets deflected
by a guide into the front division of drawer. In the inside of box there is an
electro-magnet, in front of which an armature is hung eccentrically. This armature
has one end chisel shaped and has a recess cut at back. This recess supports a
rocking lever, on one end of which is riveted a plate at right angles and on the.
other end is hinged a rod also at right angles. This rod has a plate with the
words "Late""Early" engraved upon it and terminates in a ball.
When the armature is attracted by the magnet the rocking lever is liberated
and the plate at its end assumes an angle across the box and thus deflects the
tickets into the "Late" compartment. At the same time the word "Late"
appears through a slot cut in the front of box and warns the hands that they
are late.
The withdrawal of the drawer automatically resets the mechanism for the next
operation. This resetting is done automatically by a piece of brass attached to
back of drawer, bent at an angle downwards. This as the drawer is drawn out
slips under the ball on end of rod, and replaces the rocking lever on the recess of
armature.
The hour hand of the clock is fitted with a brush of fine copper wire which
glides over contact points fixed to face of clock at the hours at which time is
taken, and close the electric circuit, consisting of a battery, wires, clock, and an
electro-magnet.
These contact points are arranged in this way. The face of the clock, which is
metal, is bored with incli holes at the various points on the dial at which the
circuit is intended to close. Brass studs, a little less in diameter than the holes,
are mounted each on a wooden rosette, which is rivetted to back of clock face, the
brass stud only projecting above the front. The stud is split and the wires from
each side carried to a terminal on top of clock. The hour hand of clock is fitted
with a small brush made of copper wire.

An Electric Automatic Time Check.
I, FREDERICK GEORGE MANLEY WETHERFIELD of No. 1 Gresham Buildings
in the City of London, Solicitor, (a communication from Charles Kennedy Jardine
of Georgetown, Demerara, Newspaper Proprietor) 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 :—
The object of my invention is to construct an Automatic Electric Time Check

page_text: for receiving the checks or tickets of employes in manufacturing establishments,
offices etc.
My invention consists in the combination with a comparted drawer, of an
electrically-operated deflector for guiding the tickets in to one or the other of the
compartments of the drawer according to whether the ticket is dropped into the
apparatus Early or Late; also in the combination with the deflecting apparatus,
of an indicating plate arranged to display the words "Early or "Late," so that
it may be seen by the employé when the ticket is dropped, all as will be hereinafter
more fully described.
DESCRIPTION OF THE DRAWINGS.
39
Fig. 1 is a vertical longitudinal section of my improved time check.
Fig. 2 is a front elevation with the upper portion thereof partly in section.
Figs. 3. 4. 5 and 6 are details to be referred to.
Similar letters of reference indicate corresponding parts in all the views.
On the box A, is mounted the metallic casing B, which communicates with the
interior of the box through the opening a.
To the box is fitted a drawer C, divided into two compartments b, c, by the
partition d. In the centre of the metallic casing B, is arranged a flat tube D,
which projects downwardly into the casing, over a transverse bar e, extending across
the casing and arranged above the partition d in the drawer C. Over the bar
e,
is
arranged a deflector f, which is pivoted in the sides of the casing B, and arranged
with reference to the flat tube D, so as to deflect the tickets dropped through
the said tube into the compartment c of the drawer C.
In the casing B, is pivoted a shaft g, to which is attached a right angled lever 1,
the shorter arm of which carries a deflecting plate i, while from the longer arm
is suspended a rod j, carrying a plate k, upon which are printed the words "Late"
and Early." The rod extends through a guide l, projecting inwardly from the
front of the casing B, and carries at its lower end a ball or friction roller as shewn
in Figs. 1, 2 and separately Fig. 3.
On a stud n, projecting inwardly from the front of the casing is suspended an
armature lever o, within the field of the electro-magnet E. The armature lever o
is provided at its lower end with a catch o¹; for engaging the lever h, and the point
of suspension of the awnature lever o is arranged at one side of the centre of gravity
of the said lever, so that the armature lever hangs normally in the path of the
longer arm of the lever h When the longer arm of the lever h is engaged by the
armature lever o, the plate is suspended in such a position as to display the word
Early" through an opening in the front of the casing B.
66
On the back of the keeper o (shewn in detail views Figs. 4 and 5) is affixed a
plate o² to catch as many lines of force as possible and thus render less battery
power necessary.
To the top of the keeper in some cases is attached one end of a spring o, the
other end of which is secured to the case B. This spring insures the keeper
being brought back with rapidity and certainty to the point at which it engages the
rocking lever h.
To the upper edge of the back end of the drawer is fastened an inclined plate p
which is capable of engaging and lifting the ball m when the drawer is pulled
out, thereby bringing the longer arm of the lever h into engagement with the catch
on the armature lever o.
When the lever h is supported in an elevated position in the manner described,
the deflector i is removed from the path of the ticket dropped through the tube D
thus allowing the ticket to fall upon the deflector f, which guides it to the com-
partment c, of the drawer C. When the lever is released from the catch on the
armature lever o, the lever drops into the position, shewn in dotted lines, swinging
the deflector i, so that the ticket dropped through the tube D will be guided
by the deflector over the deflector and delivered to the compartment b of
the drawer C.

page_text: All
The electro magnet E, is connected with a clock not shewn which closes the
circuit periodically, and allows the longer arm of the lever h to drop.
tickets dropped through the tube D before the falling of the lever h, are delivered
to the forward compartment c of the drawer C, but when the armature o is with-
drawn, and the longer arm of the lever falls, the tickets are delivered to the
compartment b.
The form of time circuit closer used in connection with the magnet E, is shewn
in electric connection with the said magnet in Figure 1. In this case the hour
hand (see Fig. 6) of the clock not shewn carries a metallic brush r and in the
angle of the clock, at suitable intervals, are inserted insulating trunnions teach
provided with contact points u, u', projecting into the path of the brush r.
When the said brush touches two adjacent_contact points, it closes the circuit
of the battery G, and causes the magnet E to become active and attract the
armature o.
Before the contact of the brush r with the points u, u' is made, the tickets dropped
through the tube D fall into the compartment c, which indicates that the person
presenting the ticket is early, while after the contact is formed and the deflector i
is tilted in the manner already described, the tickets dropped into the tube D are
deflected in the "Late" compartment b.
When the drawer C is withdrawn from the box A the engagement of the time
plate p with the friction wheel or it may be a ball m on the rod j, lifts the wheel or
ball and rod, and resets the deflector i and the plate k.
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 an automatic electric time check, the combination of a comparted drawer
or receptacle for receiving the tickets, a guide for delivering the tickets normally
to one compartment of the receptacle, and means for deflecting the tickets into the
other compartment, substantially as described.
2: In an automatic time check, the combination of a comparted receptacle, a
tube arranged above the receptacle, and an electrically-operated deflector for
directing the tickets into one or the other of the compartments, substantially as
described.
3: In an automatic electric time check, the combination with the deflector,
of an electro-magnet for operating the same and a clock provided with a circuit
closer for operating the magnet, substantially as described.
4: In an automatic electric time check, the combination of the comparted
