COMPLETE SPECIFICATION.
Improvements in Traps for Vermin.
I WILLIAM GREEN HERBERT of Imperial Chambers, Dale Street Liverpool in
the County of Lancaster, Dealer in Works of Art 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 is to provide a trap for catching rats, mice, and like vermin which
shall be self setting, and continuous, and efficient in action.
A trap under my invention consists of a chamber or receptacle provided with a
platform so disposed and pivotted centrally that part of the roof of the chamber or
receptacle is formed by the platform. A weight or spring is provided to give
rotary motion to the platform, a catch or catches is or are used to prevent
reverse motion, and a baited trigger to release the platform at the required
time. An enclosed way is provided from the floor to the roof of the chamber or
receptacle.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical section of a trap under my invention. a is a chamber or
receptacle of wood, metal, or other suitable material. is a platform pivotted by
a central spindle c, to the chamber a so as to form part of the roof thereof. d is a
weight free to move along a guide rod e. To the weight d is attached a cord f
which passes over a pulley g secured to the guide rod e, and is secured to a drum h
on the spindle c. i is a catch pivotted at ; to a standard k, and is a catch pivotted
to a standard m, n is a trigger suspended from the standard k, o shows an
enclosed way which may or may not be used, leading from the floor to the roof of
the trap.
The action of the apparatus is as follows:-
The mouse or other vermin ascends to the roof of the trap and stands on one
end of the platform so as to reach the bait which is attached to the trigger_n.
The trigger is released and the platform is turned until the end b rests on the

page_text: trigger n by the weight d, and the vermin deposited in the chamber a.
The plat-
form cannot be turned back whilst the weight d is suspended on account of the
catch and is locked when the weight is run down by the catch which prevents
motion of the trigger a.
Fig. 2 is a plan of a modification of trap in which the platform is pivotted on
the side of the trap over a depressed portion of the roof, here the platform is
actuated by a spring which operates on the spindle c by means of a wheel and
pinion p. The spring is strong enough to sweep the vermin upon the lower part
of the roof into the chamber, and a catch 7 pivotted at 'm and carried round
by the spring wheel, locks the platform by being carried behind the trigger
when the said spring is out of action. Like letters denote the same parts in
both views.
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 :-
:-
Vermin traps consisting of a receptacle provided with a rotating platform, trigger
and catches, substantially as set forth.
