EARL T. DINKINS, OF HOUSTON, TEXAS:
TRAP.Specification of Letters Patent. Patented June 2;7, 1922.
Application filed- June 20, 1921. Serial No. 478,839.To alit'wlom it may concern:
Be it known- that I. EArL T. D.TKINs. a
citizen of the United States, residing at
Houston, Harris County, Texas, have in-
5 vented a certain new and useful Improve-
ment in Traps, of which the following is a
full, clear, and exact description, such as
will enable others skilled in the art to which
it appertains to make and use the same.
10 My invention relates to traps and has par-
ticular- application to traps for the smaller
animals such as rats, weasels, rabbits, etc.
The object of my invention is to provide a
trap.which will be adapted to automatically
15 set itself after it has been operated and which
will keep the animal alive without injury.
Referring to the drawing herewith, where-
in like parts are designated by like numerals
of reference in both the views: Fig. .1 is a
20 perspective view of my trap, parts being
broken away for further clearness. Fig. 2
is a transverse section through one end of
my device, the rear side ben gin central
transverse section.
25 My titap may be made of a rectangular box
1' but it obviously may be made in-any other
preferred- form. I have shown the box as
having a step or support 2 extending from
the front side. of the- box at .a short distance
30- above the-ground. Centrally above this step
is-an opening 3. having an overhanging shelf
4 which forms a guide for a dropping door
5. It is provided for this purpose with a
row of small openings 6; adjacent the margin.
3-5 of the shelf, through which may slide the
rods 7 secured in an upper plate of the
door 5.
The supporting step 2 is- also pierced by
a curved row- of holes 8, inclosing the open-
40 ing 3 and furnishing. guides for the rods. 9
of the lower door 10. These: rods are mounts
ed- in a lower plate similar to that of the
upper door 5.
Immediately inside the door or opening 3
45 I have hinged a small platform or pedal 11
When this pedal.is-in its normal raised po-
sition it is- upon a level with the outer plat-
form or step 2, and rests its upper surface
against the lower ends of a series of vertical
50 rods 12 which are secured at their upper
ends in a frame 13 secured to the upper wall
of the box 1. This frame with the down-
wardly extending rods 12 form a small cage
or chamber 14 immediately within the
55 door 3.
Both of the doors 5 and 10 are slidablyfixed to- the front side -of the box 1. The
plate 5 of the upper door is hed iii- raised
position by-means of a small line-or cable 15,
one end of which is secured at each- end of 60
the plate 5. This cable is- passed over a
small roller or pulley 16, mounted on. the
upper front face of the cage, and from this
pulley the line passes downwardly through
an opening 24 in the platform 2, and is se- 65
cured' at 17 on the- lower--end' of the plate. of
the door 10. There is secured at the point
17 another line or cable which- runs up-
wardly through a second opening 18 in the
platform 2 and passes over a- pulley 19 at 70
the upper end of the box vertically above
the point 17, and from there-the cable passes
through an opening in the front of the box
and extends directly inward- to pass about
another pulley 20 on the side end of the 75
framework 131 and from there the line is
extended downwardly and' secured to- the
inner end of the hinged pedal 11.
As has been previously noted, there- are
two sets of these- lines, one at- each side- of 80
the door 3.
I have so arranged the comparative
weights of the doors 5n and10 and' the pedal
11 that the lower door 10 shall be slightly
heavier than the combined weight of the 85
upper door 5 and the- pedal 11.
The operation- of the device-wili be practi-
cally as follows:- Some bait is intended to
be secured within the box 1 ofthe trap, and'
within the chamber-14. immediately inside 90
the door. . An- animal in entering the door-
to get at the bait will step on, the- hinged
platform or pedal 11, and his weight will be
sufficient to cause the pedal: to drop into= the
dotted- line: position shown- in Fig. 2. The, 95
animal will therefore be precipitated down-
ward into the box portion of the trap.
When the pedal 11: drops it will by means.
of the line attached thereto raise the- lower
door 10. The lower plate with the-upright 100
rods thereon will be- forced upwardly, the
rods passing through the= guide- openings 8'
in the platform so as to partly close'the-
opening 3. As the lower door is raised, the
connections through the line 15 with the up- 105
-per door will be loosened to such an extent
that the upper door will drop by gravity,
the rods 7 passing through the openings in
the plate 4, so that the lower ends of the rods
7 and the upper ends of the rods 9 will come 110
together to close the door. This door will
be held closed as long as the pedal is in its1,420,823
