BACKGROU~D OF-THE'INVENTIO~
This invention relates t~ an anim,a~ re ~ ted
for hunters and~ more specifically, to an anima~,~iquid
lure dispenser.
FIELD'OF'THE'INVENTION
The present invention relates to an animal liquid
lure dispenser adapted to simulate a "scrape" made by
white-tailed bucks. More specifically, this inventivn
relates not only to the liquid lure dispenser, but to a
10 method of simulating buck "scrapes."
DESCRIPTION OF THE PRIOR ~RT
Liquid animal lures, which rely on specific scents
to attract particular animals, are well known. A type
of buck lure used by hunters is a liquid which gives off
the odor of a receptive estrus doe, This,lure consists
of the urine of a receptive estrus doe~ The use of the
buck lure, however, has not met with a great deal of
commercial success because of its method of application.
In many instances, the liquid is commonly used by satu
20 rating a wad of cotton with the liquid and carrying the
saturated wad of cotton in the hunter's coat, so as to
attract the buck to the hunter. The liquid has a very
strong and rather unpleasant odor. Since the hunter
carries the saturated wad of cotton in his pocket ?
the odor from the,liquid permeates the hunter's c~othing

and prnvides,the hunte~'s clo,thi~g with an u~pleas~nt Qdor
~hich is retai~ed,long'after the,hunti~g season is over~
One method of applying the,lure is'to dispense the li~uid
lure through a conventional plastic squeeze bottle with a
nozzle top. There~ore, the h~mter squeezes the bott~e to
apply drops of the,lure as he walks along the desired
trail. Maintaining the desirable application rate while
walking through the woods or along a trail can be a tedious
chore for the hunter. Additionally, the advantageous
10 app].ication of the lure to the trail is overcome by the
scent of the hunter himself. Therefore, the spari~g
application of the liquid along the trail is not sufficient
to overcome the 'buck's natural apprehension of the huma~
scent. Applicant is aware of U. S. 2,959~354~ to
Edward W. Beck, of Yeadon, Pennsylvania~ who has discl~sed
a cup-shaped container, which has a tubular ste~ extending
from the bottom of the container and a cover threadably
fixed on a threaded rod, secured to the top of the cover
so that the top of the container could be opened or closed
20 upon rotation of the cover.
The container contained a liquid lure membe~, havi~g
the odor of a doe so that the container could be suspe~ded
in position and opened slightly to ~llow the scent of the
doe's urine to permeate the area and,thus,lure the buck
into the proximity.

trails along the ground and e~uipped wi.th a valve. SQ as
to regulate a reguIar application of.the doe's u~ine along
the trail of the hunter9 .This latter procedure is known
as a liquid trail.lure.
SUMM~RY OF THE INVENTION
According to the present invention, there .is provi~ed
a dispenser for animal liquid lures which can be used to
simulate the natural habitat of the deer and which can be
10 set up so as -to provide a buck "scrape." This scrape can
either be a scrape made by the buck or a simulated scrape
produced by the hunter. In any event~ the apparatus of
this invention is suspended from a.branch over~a~ging:the
scrape and the doe's urine flow from a vial into a drip
chamber and through a dispensing.tub~ in slow, well~
regulated drops. The dispenser is made so.that it.will
dispense as little as one ounce of doe's urine for a period
of up to 30 hours. Therefore, the hunter can set up the
lure the night prior to the hunt and mask.his sce~t with
20 fox or skunk urine lure, so that the buck does not pick
up the hated human scent. In this manner~ the hunter can
then approach the site the following morning and set up
his blind, awa.iting the approach of bucks.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A buck "scrape" is a circular or oval patch of ground,
20 made by a mature buck prior to the rut. The earth is torn
up by bucks, who use their front feet to clear the piece
of ground. Scrapes are from 12 inches in diameter to
3 feet. Most scrapes are made in a frenzy of pawing ? as
if the animal has opened a relief valve. The tracks show
that the deer pivots around while making the scrape, The
scrapes are usually made in trails that are heavily used
by does. Almost all scrapes are made under,low-hanging
--4--
d ~!3 3 ~L ~ 3
branches. ~ mature buck'wil~ ma~ke ,these ,al~ ~v,e~,his
territory. The buck'checks these at differe~t times Qf
the day and night.
The scrape is marked with the scent o~ the buck.
The white-tailed deer have four exte~nal sets of glands:
preorbital ~tear duct), interdigital (between the hooves),
tarsal (on the inner side of the hock) and metatarsal
(on the feet). The buck will urinate in the scrape,
letting the urine run down his leg. He will ,also rub the
lQ preorbital glands on the over-hanging branches above the
scrape. Some bucks will chew the,leaves on these b~nches
to further leave his scent. A receptive doe will urinate
in the scrape and browse around the area till the buck
returns. If the buck that made the scrape is with a doe.
he will not leave a hot doe to find another. Often, other
bucks will check scrapes that they did not make.
receptive doe will walk with her tail straight out and
slightly shifted to the right or left.
The apparatus of this invention is adapted to make use
20 of existing scrapes or to simulate scrapes and to dispense
a receptive estrus doe's urine, which is commercially
available, into the scrape to attract the buck, The,hunter
will then set up a blind or will situate himself in a tree
and wait for the buck, downwind of the scrape.
Referring now to the drawing~ the apparatus consists
of a vial,l, having a threaded neck 2, which contains a
cap 8. A cap of this type is commercially available and
-5-
~2 ~
can be carried easily by the hunter i~ his ~ocket withoutfear of,leakage. The cap conta.ins a threaded sklrt 9 ,a,~d
solid top 10 and a liner'.(not shown),
However, when utilized with the apparatus of,this
invention, the solid cap 8 is replaced wi,th ~ cap 3, w~ich
again has a threaded skirt 4 and a top portisn 5, ha~ing
an annular flange 6, defining a centr,al opening'7, A
liner, preferably made of Teflon, 11 is ~itted i~to the
cap and it normally contains a hole 12 (see Fig. 9).
10 The hollow spike 15 of the top of the microdrip app,a,ratus
13, is inserted through the hole 12 of the Teflo~ liner ~1.
The hollow spike,15 is a part of the top,14. of the drip
chamber and contains a fluid passage 16, which ~eads to a
capillary tube 17, fixed in a support member ~8, T,h,e
other hole 19, along the side of the hollow spike 15, is
an air passage, leading to a carbureting de~ice 20, which
contains a valve chamber 21~ containing a ball bearing 22,
which seats against a valve seat 23. The.valve,chambe~ 21
is in communication with the air inlet 24. The carbureting
20 device 20 is normally covered with a carbureting device
cover 25 and the hollow spike 15 of the top of the micro~
drip chamber is normally covered with a hollow spike
cover 26. As illustrated, both in Fig. 1 and in Fig. 7
the top of the microdrip apparatus has two proje,cting
tabs 27, each of which contains a hole 28.
As is shown, the capillary tube 17 is in c~munication
with the drip chamber 31. The drip c~amber contains a
-6
.,.,, ~ .
scribed fill line 3~ and..terminates. at its dist~ e~d
with a nipple 33. ~ dis.pensi~g tube 34 is f-ixedly
secured inside the nipple. The dispensing.tube is
trained through clamp member 38, which ? as is shown in
Fig. 3, has a beveled floor 39. and tw~ upstanding w~ls 40,
each of which contains a slot 41. . The wheel membe~ 50 is
journaled in the slots 41, by means of pi~ot pins 5~ so
as to exert increasing pressure on the tube trained
through the clamp 38. A weight 53, in the form of a
10 round fishing sinker, is located at the di.stal end of the
dispensing tube 34, so as to hold the apparatus perfectly
vertically over the scrape.
As is shown in Fig. 2, a simulated scrape 60 can be
prepared by the hunter by use of his rattling antlers 61
or an abandoned or not-abandoned scrape can be utilized
if one can be located. As previously indicated, the rut
scrapes are almost always located under overhanging
branches and the mature buck nibbles away on the twigs
and leaves, so as to leave a scent from his saliva
20 around the branches.
In this instance, however, the apparatus is hung over
the branch, by releasing the flat-headed screw 55, by
twisting the flat head 56 and removing the threaded shank
57 from the interior bore of the suspending tube 54. Thus,
the one end of the tube can be rernoved from the hole 28 in
the tabs 27 of the top of the drip chamber and the entire
apparatus hung onto the branch. Thereafter, the suspending
--7--
tube 54 is trained through hole 28 and the shank.57 of
the flat-headed screw 55 is reinserted so that the flat
head 56 is in engagement wi,th the undersurface of the
tab 27. Thereafter, a rubber band 63 is located.near
the bottom end of the inverted.vial to hold the.suspe~ding
tube vertically in suspension a'bove the serape 60,
By setting up the scrape t'he day or evening prior to
the hunt, the hunter can mask his footsteps with a masking
scent, such as fox urine or skunk urine, so that the human
10 scent is not available around the site. Thereafter, on
the next morning, the hunter can approach the site down-
wind and set himself up in the blind, ready to take his
next buck.
As previously indicated, a vial of one ounce of doe's
urine will last as long as 30 hours, which will allow a
hunter two days or more in which to hunt the area.
How To Assemble
The scent is poured into the vial 1. Thereafter,
liner l'l is placed into cap 3, flush against the annular
20 flange 6 of the top 5. Cap 3 is then screwed onto the
threaded neck 2 of vial 1. The hollow spike cover 26 is
removed from the hollow spike 15 of the top 14 of the
microdrip apparatus 13~ The hollow spike is pushed
through hole 12 of the Teflon,liner,ll and into the vial 1.
Wheel 50 is turned to close clamp 38. Thereafter, vial 1
is inverted and the carburetor cover 25.is removed. .The
drip chamber 31 is squeezed until the liquid lure is at
--8--
the,level.of.,the scribed fi~l ~ine 32, :,T,he. suspend,i~g
tube 54 is covered with..rubber band 63 ~nd ,thexeby. anchQ~e~
to the bottom portion of.vial,l. The suspending 'tube 54
is attached to the branch above scrape. 60. :(This:may
entail removal of. the fla,t-headed scre~ 55'fro~ ,t~e e~d
of the suspending tube and training the free end Q~ ,the
suspending,tube over the branch and thereafter reinserting
the threaded shank 57 of the flat-headed screw 55 back
into the bore of the suspending tube 54.) The wheel 50
10 of clamp 38 is now turned to open the clamp 38 and to
regulate the flow of the lure through the dispensing
tube 34. The drip chamber 31 is so regulated that four
drops of the lure from the vial 1 through the capi~lary
tube 17 into the drip chamber is equivale~t to one drop
of the distal end of the dispensing tube 34. For this
reason, one ounce of the lure can last for as long as 30
hours at the site of the scrape.
How to Remove and Disassemble'thè Apparatus
At the termination of the hunt, the apparatus is
20 removed from the branch by removing the flat-headed
screw 55 and the suspending. tube 54 from hole 28, as
previously indicated and the entire apparatus can be
inverted, so as to allow any unused lure to run back
into the vial. Thereafter, the cap 3 can be removed and
the regular cap 8 can be placed on the.vial,. so that the
lure can be placed in the hunter's pocket without fear
of leakage. The drip chamber 31 can be rinsed out with
_g_
a3~
water and placed back with the,huriter's p~xapher~ia
for reuse on another hunt.
While it is clear that ,this apparatus,has bee~ set
up primarily for hunting deer, it can also be used .for
other animals, such as bear and the,like.
