PROVISIONAL SPECIFICATION.
Improvements in Appliances for Use in Poisoning Rats and other
Vermin.
A communication from abroad by MICHAEL KELLY, of No. 204, East 21st Street,
in the City and County of New York, State of New York, United States of
America, Chiropodist.
1, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, London in the County
of Middlesex, Consulting Engineer and Chartered Patent Agent, do hereby
declare the nature of this invention to be as follows:-
The device is a masked trough designed to be used with poisoned food or water,
for the destruction of vermin, as rats, mice and sparrows. It provides for easy
access of the creatures for which it is intended, and forbids the access of larger
beasts or birds. The form also prevents the larger creatures from seeing the
contents.
I mount on a board or other reliable support a sheet of metal, curled, so as to
bring the edges approximately together, one edge overhanging, or standing
considerably farther outward than the other. Pieces of wood or metal secured
just within the ends sustain the sheet metal and constitute therewith a strong and
tight case.
The device should be so adjusted that a part overhangs at a proper height,
allowing sufficient space under it for the desired animals or birds to move in and
out while forbidding the access of larger animals or birds.
The device may be made of various sizes for different uses. An open space of
about two inches in height under the mask will serve for rats, mice, and the
belligerent and destructive sparrows.
The main portion of the opposite edge of the sheet metal is folded so as to form
a smooth edge over which the small animals and birds which it is desired to destroy
can easily reach to obtain the food within. The edge left higher adjacent to
each end, to prevent the larger animals or birds from seeing the food, and as a
guard to prevent any from reaching inward by any possibility except by crawling
under the low over-hang edge.
Instead of sheet metal, and separate pieces of wood for the ends, the whole may
be made of cast iron, molded thin. The foot may be formed integral therewith.
I can use various materials. Wood may serve.
I propose as a modification, which may have some advantages, to make the whole
of cast iron, or crockery, and instead of making the device straight, curving it so
that it shall form an endless ring with the overhang on the outside. Other
modifications may be made by forming it in a semi-ring, or in two straight parts
joined with an angle, V-shaped.
One modification may be in the form of a trough with a hood sufficiently larger
held at a proper height and overhanging on all sides. In all forms the hood
overhangs so as to forbid the access of the larger creatures, and so as to prevent
their seeing the food or water therein.
For convenience in filling and cleaning, the hood in some forms may be made
separate and fitted upon posts and secured by removable keys.

page_text: The device should be exposed out of doors only in the country where the
sparrows are objectionable, but for rats and mice wherever they are found.

SPECIFICATION.
Improvements in Appliances for Use in Poisoning Rats and other
Vermin.
A communication from abroad by MICHAEL KELLY, of No. 204, East 21st Street,
in the City and County of New York, State of New York, United States of
America, Chiropodist.
I, WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, London, in the
County of Middlesex, Consulting Engineer and Chartered Patent Agent, 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 device is a masked trough designed to be used with poisoned food or water,
for the destruction of vermin; as rats, mice and sparrows. It provides for easy
access of the creatures for which it is intended, and forbids the access of larger
beasts or birds. The form also prevents the larger creatures from seeing the
contents.
The accompanying drawings form a part of this Specification and represent
what my correspondent considers the best means of carrying out the invention.
Figure 1 is a general perspective view.
Figure 2 is an end view, and
Figure 3 a front view of the two ends, partially in vertical section.
The remaining figures represent modifications.
Figure 4 is a plan view showing the device in an annular form.
Figure 5 is a section on the line 5-5 in Fig. 4,
Figure 6 is a plan view showing an oblong form.
Figure 7 is a section on the line 7-7 in Fig. 6.
Figure 8 is a corresponding section showing a modified form of the hood.
Figure 9 is an end view corresponding to Fig. 8.
Similar letters of reference indicate corresponding parts in all the figures where
they appear.
A is a board of pine or other suitable material, adapted to lie on the ground or
floor, and to form a reliable support. B is a sheet of zinc or other metal, curled
as shown, so as to bring the edges approximately together, one edge B'overhanging,
or standing considerably farther outward than the other. CC are pieces of wood
or metal secured just within the end so as to sustain the sheet metal and constitute
therewith a strong and tight case. DD are nails or screws inserted through holes
in the sheet metal exterior to the ends C, and securing it in the desired position on
the foot A.
The device should be so adjusted that the part B₁ overhangs at a proper height,
allowing sufficient space under it for the desired animals or birds to move in and
out while forbidding the access of larger animals or birds.
The device may be made of various sizes for different uses. My correspondent
has in his experiments made the device thirty (30) inches long, and the main
portion two (2) inches radius, allowing the part Bí to overhang or extend two
inches further. This device, so fixed on a board as to leave an open space of
about two inches in height under the mask, will serve for rats, mice, and the
belligerent and destructive sparrows.
:

page_text: The ends C C are each formed with a wing C adapted to support and properly
stiffen the over-haug B', of the sheet metal. The main portion of the opposite
edge of the sheet metal is marked B', and is folded so as to form a smooth edge
over which the small animals and birds which it is desired to destroy can easily
reach to obtain the food within. The edge is left higher adjacent to each end, as
indicated by B. This higher portion extends up to the level of the edge B', and
serves to prevent the larger animals or birds from seeing the food, and as a guard
to prevent any from reaching inward by any possibility except by crawling under
the low over-hung edge B', or the wings C' at the ends.
Modifications may be made without departing from the principle or sacrificing
the advantages of the invention. Instead of sheet metal for the part B, and
separate pieces of wood for the ends C C, the whole may be made of cast iron,
molded thin. In such case the foot may be formed integral therewith. I can use
various materials. Wood may serve.
I propose as a modification which may have some advantages, to make the whole
of cast iron, or crockery, and instead of making the device straight, curving it so
that it shall form an endless ring with the overhang on the outside. Figures 4 and 5
show such a modification. Other modifications may be made by forming it in a
semi-ring, or in two straight parts joined with an angle, V-shaped. With either
of these forms, which will be obvious without drawings, it will lie on a floor or on
the ground reliably, without feet.
Figures 6, 7, 8 and 9 show modifications made in stout sheet metal and in the
form of a trough with a hood sufficiently larger held at a proper height and
overhanging on all sides. Fig. 7 shows the hood with a hanging lip. Fig. 8 shows
the hood without such lip. In both forms the hood overhangs so as to forbid the
access of the larger creatures, and so as to prevent their seeing the food or water
therein.
For convenience in filling and cleaning, the hood in each of these latter forms is
made separate and fitted upon posts and secured by removable keys.
The device may be placed where the pests frequent. It should be exposed out
of doors only in the country where the sparrows are objectionable, but for rats and
mice wherever they are found.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
1 claim is:-
1. The feeding device herein described comprising a trough of imperforate
material and having an overhang or hood projecting forward and downward below
the alignment of a longitudinal slot in said trough, as herein specified.
2. The feeding device herein described, having a longitudinal opening therein,
a foot or support for said trough, a hood or overhang in proximity to said slot,
and guards or screens at the extremities of said slot to prevent access to the trough
at those points, as herein specified.
Dated this 20th day of April 1894.
