PROVISIONAL SPECIFICATION.
Improvements in Traps for Mice, Rats, and other Small Animals.
I, ANDREW HOGG of the firm of Adam Hogg & Sons, Sawmillers and Wood
Turners in the Town and County of Kirkcudbright, do hereby declare the nature of
this invention to be as follows :-
This invention which relates to traps for mice rats and other small animals
consists in the application of mechanism in conjunction with the spring and the
usual throttling loop whereby the compression of the spring is more easily released and
the loop put into operation to choke the animal than is the case with ordinary traps.
Under the invention there is hinged or jointed to the fore part of the spring a
latch or loop which has two projecting tails or ends these in setting the trap being
entered under a staple or bar by which the spring is held downwards in compression.
After the ends are so entered the bend of the loop is passed over a trigger or catch
made at the upper end of a lever piece which under the trigger is centred on a bar
or rod fixed in the top of the trap. The lower part of the lever piece passes
through a hole in the top and at the interior of the trap it is spread in the usual
way to create an obstruction in front of the bait. In attempting to get at the bait
the animal swings the said lever piece whereby the trigger at its upper end is
released from the loop of the catch the effect of which is that the spring flies
upwards bringing the throttling loop into operation.
Dated this Twenty-third day of July 1890.

COMPLETE SPECIFICATION.
Improvements in Traps for Mice, Rats, and other Small Animals.
I, ANDREW HOGG of the firm of Adam Hogg & Sons, Sawmillers and Wood
Turners in the Town and County of Kirkcudbright 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:-
This invention which relates to traps for mice rats and other small animals
consists in the application of mechanism in conjunction with the spring and the
usual throttling loop whereby the compression of the spring is more easily released
and the loop put into operation to choke the animal than is the case with ordinary
traps.
The invention is illustrated under two modifications on the accompanying
drawings and under one arrangement seen in elevation at Figure 1 and in plan at
Figure 2 there is hinged or jointed to the fore part of the spring a, a catch or loop
which has two projecting tails or ends 6, 6 these, in setting the trap, being entered
under a staple or bar c by which the spring a is held downwards in compression.
After the ends are so entered the bend of the loop is passed over a trigger or
catch d made at the upper end of a lever piece d' which under the trigger is centred
on a bar or rod e fixed in the top of the trap. The lower part of the lever piece
passes through a hole in the top and at the interior of the trap it is spread in the
usual way to create an obstruction in front of the bait. In attempting to get at the
bait the animal swings the said lever piece d¹ whereby the trigger d at its upper
end is released from the loop of the catch the effect of which is that the spring a
flies upwards bringing the throttling loop finto operation.

page_text: Under the second arrangement seen in elevation at Figure 3 and in plan at
Figure 4 the catch b instead of being centred on and swinging upon the spring a is
centred upon the staple or bar c.
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 :-
In a trap for rats mice and other small animals the means for holding down and
releasing the spring a and throttling loop fand consisting of a catch band trigger d
arranged substantially as described with reference to Figures 1 to 4 of the
accompanying drawings.
