1 Claim.
The invention is an improvement upon that
shaft -or tubular member l2'in either direction
disclosed inan application for Letters Patent of
the United States by Newton Mans?eld, Serial
No. 73,021‘, ?led April 6, 1936, in' which means
will have like effect in delivering a charge of the
5 are provided responsive to‘ the movement of the
body of the-animal. Springs 29 restore the pump
applicator, induced by contact with the passing
animal, for supplying the insecticide from a res
ervoir to the applicator for its‘ distribution upon
the animal. Certain features of the apparatus
10 shown but not claimed herein are claimed in said
application Serial No. 73,021, ?led April 6, 1936.
The invention ‘concerns the features, combina
tion and arrangement ‘of parts hereinafter de
scribed and particularly pointed out in the claim.

liquid insecticide through the distributing system
to the pads which apply the insecticide to the
piston to its normal position.
The inlet to the pump cylinder 3! is connected
by a pipe 32 through a suitable check valve 33 to
a reservoir orsupply tank vb. , A cock 34 and
strainer 35 may be applied to this connection.- VAn
outlet pipe 36 from the pump has a suitable check
valve indicated generally at 31 permitting egress
of the insecticide from the pump, but preventing
back ?ow to the pump cylinder 3! from said pipe
35. A suitably packed swivel joint 36x connects ' .15
the pipe '38 with the tubular'member l2 through
the journal 25 which is hollow as indicated in
'Fig. 1-, so that the journal despite its rotation
serves as part .of the' conduit for the ?ow of the
insecticide. Check valve 33 permits inlet of the ,
?uid to the pump from the reservoir, but prevents

The member 59 is employed for applying the
insecticide to the animal, and is termed for con

The tubular member in the present invention

has but one outlet.v This is controlled by a needle '
valve 38 carried by a piston 49 within a cylinder ,

the chambered part, but so far as the mounting
of the nozzles is concerned it is immaterial
These coupling members receive the ends of
the pipes c, c1 and the couplings are provided with
suitable passages to allow the ?uid to pass tov
the nozzles from the distributing pipes. These
nozzles connect with ?exible? conduits 44, 45 car
ried by the ?exible blanket or canvas member to
convey the ?uid to the distributing pads (not
10 shown) mounted on the canvas member at the
lower part thereof. The several nozzles and their
corresponding couplings are respectively substan
tially alike in structure and in the size of their
ports and in order to get the delivery of an
15 amount of ?uid at one point or points diiferent
from that delivered to another point or‘points a
disc 71. is seated between the nipple e and its
corresponding nozzle d.
The opening'in the disc is of a diameter to
20 determine the amount of ?uid which shall be de
livered at that particular nozzle, and by using
discs having di?erent sizes of apertures relative
to each other the ?ow of ?uid to one part of the
applicator may be greater or less as may be de
25 sired relative to the amount delivered by another
nozzle to another part of the ?exible hanging of
canvas or other material.
The use of these perforated discs will avoid the
necessity of having’ adjustable manually op
'30 erable valves.
If desired uniform delivery may
take place at all the nozzles by using discs hav
ing perforations of proper sizefor this purpose.
Delivery occurs only when there is a rise of
pressure, within the tubular member l2 and since
this rise of pressure is communicated to the ?uid
throughout the whole system of conduits and
nozzles when the single needle valve lifts there
whether or not the member is chambered be
cause all of these nozzles are controlled from
the one valve.
The apparatus takes care of varying degrees
of delivery in respect to differences in the in
tervals of time between operations and di?erent
demands consequent upon the difference in the 10
sizes of the animals treated, or the variations due
to the difference in size between different parts
of the same animal. It also takes care of varia
tions in the movement of the animal or animals
‘past the blanket, so that waste is eliminated by 15
varying the supply of insecticide according to the ~
demand. ‘The position of rest of the apparatus
may be that when the blanket is hanging verti
cally, or it may be any position of the rocking
member 12 at which the main valve 38 is closed 20

will cause the rotating member l2 to move
through an angle of about 15°. This movement
will cause the needle valve 38 to open and dis

only when an animal seeking, for instance water,
caused the piston to move up only about one
‘third of its travel. The valve then closes as the
pressure in the tubular member has been re
lieved. 'The animal has thus supplied to the 40
Wiping member only what it‘ took out to apply
the proper dose to its neck and shoulders“ It
should be borne in mind that the animal is now
standing at rest under the blanket and the rotat

the passing animal. At other times when no ani
After standing with neck and shoulders under
the blanket for a period of time, the needle valve 50
‘being closed, and only about one third of the
required dose having been discharged by the
pump the animal again moves forward and passes
out from under-the blanket. This forward move
ment of the animal causes the rotating tubular 55
member to be further rotated to its extreme
angle, viz. zl5“-—or 30° ‘more than when the animal
was standing with neck and shoulders under the
blanket. Now this increased angular motion of
the rotating tubular member causes the piston 60
will be a delivery of .the ?uid at each of the
nozzles. When the needle valve closes due to the
pressure dropping within the system the ?ow at
all the nozzles will stop.
As to the general characteristics of the ap
paratus these are the same as in the application
above referred to. Among .these may be men
tioned that the apparatus feeds the ?uid to the
delivery points on the flexible blanket or canvas
mal is passing or if the animal rests while in
contact with the blanket no feed of ?uid will
take place.
Further, the amount of ?uid de
livered will vary with the size of the animal, a
55 large one moving the blanket to a greater degree
than a small animal.
The pumping apparatus is preferably placed at
a point at the inner side of one of the uprights I l.
The member 22 which depends from the mem
60 ber 12 to be operated by the movement of the
canvas hanging may be covered by a padding
255 of any suitable material to take wear.
An opening it may be formed ‘in the member
331) in line with the needle valve seat 38a and.
this opening may be closed by a screw threaded
plug m.
While we have described what weregard as a
practical and economical form of the apparatus
it will be understood that we do not limit our
70 selves to the exact construction disclosed, but
variations therein may be made within the scope
pf the appended claims. Thus, as an instance,
‘the member l2 need not beitubular throughout.
One purpose of itschambered formation is to
\ receive the ?uid forced by the pump and make
in the pump to move up the balance of its stroke.
This causes an increased pressure in the tubular
member and the needle valve again opens and. ‘
‘discharges the remaining two thirds of the dose
to the wiping pads which have been moved by the
after part’ of the animal’s body in passing out
from under the blanket.
We claim:
In combination, an applicator member
mounted to be moved by a passing animal, a 70'
rockable member operated by the movement of
the applicator, said rockable member having a
chamber associated therewith, a reservoir for in
secticide ?uid in communication with said cham
ber, a pump operated by the rocking member for
delivering liquid from said reservoir to said
chamber, a valve automatically delivering liquid
from said chamber, and a distributing system
delivering ?uid to the applicator member com
(Fl prising conduits extending from di?erent points
along said rocking member, and conduit means
extending from and controlled by said valve and
supported by said rocking member to ' deliver
liquid from said chamber to said distributing
conduits, substantially as described.
