A A Trap for Catching Rats, Mice, and other vermin.
Year: 1897

page_text: I, HUGH ALEXANDER MARDON, of 40, St. Alphonsus Road, Clapham, Surrey, of
no occupation, do hereby declare the nature of this invention to be as follows:-
A box or passage in parallel form open at the top and closed at the sides bottom
and one end with a bar across the top and the enclosed end. The sides are either
sloped at any angle sufficient to cause a lid which on being raised to a point towards
the upper end will fall to the lower when released from a fixed position and are
grooved or the sides may be of any other form if fitted or grooved at a like angle.
Into the grooved space a lid of less length than the top of the box is inserted.
The lid is raised to to a sufficient heighth to form an opening & is kept in position
by a bar across the box inside or outside to which an arm or trigger is attached with
a loop at one end & turned up at the other. To the trigger a hook is attached.
The upper end of the lid is fitted with a moveable attachment running into hinges
or eyes formed of two arms in part parallel to the lid & then turned up per-
pendicular to the plane of the lid of such length as when the lid falls the attachment
falls with it and the lid is kept closed by its pressing against the bar across the
end of the box.

A Trap for Catching Rats, Mice, and other vermin.
I, HUGH ALEXANDER MARDON, of 40, St. Alphonsus Road, Clapham, S.W., of no
occupation, 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:-
A box or passage in parallel form open at the top and closed at the sides bottom
and one end. The sides at one end are sloped at any angle sufficient to cause a
lid to fall when released from a raised position. There are grooves in the sides in
which the lid slides. The lid is raised to a sufficient height to form an opening
and is kept in position by a trigger carried by a bar fixed across the box either
inside or outside.
To the trigger a hook is attached. The upper end of the lid is fitted with an
attachment pivotted to the lid at a suitable distance from the top and having two
L shaped arms of such length that when the lid falls it is kept closed by the arms
of the attachment pressing against a bar fixed across the top of the box.

page_text: The drawings attached to the specification show traps made in accordance with
this invention.
Figure is a longitudinal section, Figure 2 is an end elevation with the end
removed and Figure 3 is a plan with the top removed of a trap in which the bar
carrying the trigger is inside the trap.
Figure 4 is a longitudinal section of a trap in which the bar is outside; and
Figure 5 is a similar view of a trap but in this case instead of the trigger carrying
a hook, it is connected to a pivotted platform.
In all the figures the traps are set that is the lids are held open by the triggers.
a a are the sides and 6 the bottom of the trap.
In the sides a a are grooves c in which a lid d slides. When the lid d is shut it
is locked by the arms e of the attachment f engaging with a bar g fixed to the
sides a a. The attachment f is pivotted to the lid at a suitable distance from
the top as is shown in the drawings. The end of the trap is held in a groove b¹ in
the bottom b and is secured by catches i.
Referring to Figures 1, 2 and 3 the lid is held open as is shown in full lines by
the upturned end of a trigger k carried by a bar inside the trap. To a loop
on the trigger is attached a hook m on which the bait is placed. The position of the
trigger and the attachment after the lid has fallen are shown in dotted lines in
Figure 1.
In Figures 4 and 5 the bar is outside the trap and the trigger engages with the
top and centre of the lid respectively.
In Figure 5 the hook m is dispensed with and in its place is a platform n pivotted
at o and connected to the trigger by links pat each side of the trap; so that the
weight of the animal tilts the platform and releases the lid.
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 a trap a sliding lid held open by a trigger substantially as described.
2. Means for locking the lid substantially as described.
3. Traps substantially as described and shown in the drawings.
