COMPLETE SPECIFICATION.
An Improvement in Vermin and other Spring Traps.
I, NICHOLAS WILLIAM LOBB, of Trenault, Launceston, in the County of
Cornwall, Gentleman, 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:-
My invention relates to an improvement in vermin and other spring traps.
I attain this object by the means illustrated in the accompanying drawing, in
which:-
Fig. 1, is a plan of the trap set with the roller projection.
Fig. 2, is a side view of the arm or lever with the roller.
Fig. 3, is a side view of an arm or lever without a roller.
Similar letters refer to similar parts throughout the several views.
To the jaws e spring and bottom iron and platform 6 of the ordinary metallic
rabbit or vermin trap is rivetted to the bottom iron a cross piece h one end being
slightly raised to receive the jaw of the trap when set. At the other end of this
cross piece are two fingers or jaws between which is pivotted a V shaped piece of
metal with an arm or lever a or e. The bottom of this piece of metal has a pin
hole g for securing it between the fingers of the cross plate by a pin. At the top
inside the opening of the arm a is a roller or wheel d, or a solid metal projection e
as in Fig. 3. The jaw c on being pressed into this opening lifts the arm or lever a
or f to the end of which is attached the tiller plate or platform b and brings the
roller or wheel d or projection e over the jaw c of the trap securing it set until
pressure is applied to the tiller plate or platform b.
The object of my invention is to provide at the ends of the setting lever an
apparatus that will release the jaw of the trap directly any animal place their feet
on the platform, and to do away with the costly construction of uprights or tongues
now in common use.
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 vermin and other spring traps, the combination of the V shaped piece of

page_text: metal with the arm a with a roller or wheel d, and pin hole g for securing the
V shaped piece of metal to the cross plate / between the jaws or fingers,
substantially as herein described and according to Figs. 1, and 2, of the
accompanying drawing.
2. In a vermin and other spring traps, the combination of the projection e and
the V shaped piece of metal with the arm secured to the cross plate h between
the jaws or fingers by a pin passed through the hole g, substantially as herein
described and according to Fig. 3, of the accompanying drawing.
3. In a vermin and other spring traps, the combination of the plate or platform
rivetted to the lever or arm, substantially as herein described and according to the
accompanying drawing.
Dated this 8th day of April 1893.
