lar member 6, which inclines at an angle
corresponding to that of the flared periphery
of the drum 4, to which it is attached. The
member 6e extends a suitable distance below
5 the drum, where it joins a horizontal tubular
member 6f, which connects with a burner A.
The burner A consists of a short tube, the
upper end of which is provided with a very
small hole b, while the lower end is inter-
10 nally threaded and receives a threaded rod
C, which at its lower end is provided with a
hand-wheel D, while its upper end is pointed,
as at E, to enter the hole B, as shown in Fig.
2. A jam-nut f on rod C contacts with the
15 lower end of the burner-tube A and limits
the upward movement of the rod. The
pointed end E regulates the flow of oil or
gasolene when the hand-wheel D is turned or
shuts off the supply entirely when desired.
zo The burner is braced by a support I, which is
secured to it and to the bottom of the drum.
Just above the burner-tube A and secured
to a disk which forms the bottom of the heat-
ing-drum 4 is a tube G, which forms a chim-
25 ney for the flame and directs it into the drum.
The heat generated by the flame passes up
through the plate 2 into the hollow letter or
character forming the brand, which is pro-
vided with a number of small holes iA to in-
30 duce a proper draft and to permit the es-
cape of any smoke. The burner-tube near
its lower end is provided with a drip-cup H,
which is designed to catch the overflow oil or
any residuum which may collect while the
35 implement is in operation.
The oil-reservoir 8 consists of a metal tube,
which is of sufficient length to hold a quan-
tity of oil or gasolene. The upper end is
closed by the cup 7, as before stated, and the
40 lower end is threaded externally and receives
a threaded cap 9, to which the handle 10 is
secured. The handle 10 has a cylindrical
bore, in which is fitted an ordinary air-pump
11, the upper end of which is secured within
45 an opening formed in the cap 9 and is pro-
vided with the usual valve 12. The piston
13 and rod 14 are of the common type, and
the free end of the rod is provided with a
grasping portion 15, which when the rod is
5o pushed in forms an ornamental end to the
handle 10. A notch 16 is formed on one side
of the grasping portion 15, which is engaged
by a spring-catch 17, secured to the handle
10, so that the rod 14 may be held within the
55 pump-cylinder and out of the way of the op-
erator when not in use.
The reservoir 8 carries a piston 18, which
is inserted after the reservoir has been sup-
plied with a sufficient quantity of oil or gaso-
6o lene and is designed to move toward the up-
per end of the reservoir under pressure of air
from the air-pump 11, thus forcing the oil to-
ward the feed end of the reservoir and insur-
ing a constant and even feed to the burner.
65 The bolt which secures the parts of the piston
18 together is provided with an eye 19, to
which a chain 20 is attached and by whichthe piston 18 may be withdrawn from the
upper end of the reservoir 8 when it is desired
to refill the same. 70
In order to insure a proper draft to the
burner and to prevent the flame from being
extinguished should the implement be used
when the wind is high, a hood 21 is provided,
which fits around the bottom of the drum 4 75
and incloses the burner. A lug 22 projects
from one side of this hood, which has a circu-
lar opening 23, designed to inclose the bracket
5, and a threaded opening, which receives the
thumb-screw 24, by means of which the hood 8o
is held in its normal position or permitted to
be slid down in order that access may be had
to the burner. The bottom of the hood is
provided with a circular opening 25, which is
slightly greater than the diameter of the drip- 85
cup H. This opening furnishes air to the
burner and permits the hood to be slid below
the drip-cup II, as will clearly appear by ref-
erence to Fig. 2. A slot 26 is formed in the
wall of the hood opposite to the lug 22, and 90
this slot overlies the member 61, of the bracket
6 when the hood is in position.
In Fig. 4 a different formof hood is shown,
consisting of a metal cylinder 27, which ex-
tends from the upper end of the reservoir 8 95
to a point slightly beyond the face of the
branding-iron, enclosing the same and all the
mechanism connected with the heating there-
of. This hood 27 is designed to have a slid-
ing movement upon the reservoir 8, 4nd to 1oo
this end the diaphragm forming the bottom
is provided centrally with a depending neck
28, the circumference of which is the same as
that of the reservoir, which it surrounds and
upon which it slides. A helical spring 29 en- io5
circles the neck 28 and bears upon the bot-
tom of the cylinder and upon a collar 30,
which is secured upon the reservoir 8 by a
thumb-screw 31. The hood 27 is thus nor-
mally held so that its upper end will be be- Ito
yond the face of the brand, and excessive up-
ward movement thereof is prevented by the
cap 7 on the upper end of the reservoir, which
acts as a shoulder against which the bottom
of the hood abuts. The periphery of the hood, 115
at the lower end thereof; is provided with a
plurality of perforations 32, and the dia-
phragm forming the bottom is also perfo-
rated, as shown at 33, and these perforations
admit air to the burner. In order that access 120
may be had to the burner A and hand-wheel
D, the hood is provided with a sliding door
34, which normally covers an opening 35 in
the said hood, through which the fingers may
be inserted to manipulate the hand-wheel 125
or light the burner. This hood 27 not only
protects the branding-iron and burner, but
prevents the flame from being accidentally
extinguished. In branding an animal with
this form of device the upper end of hood 27 130
first comes in contact with the animal, and
by pressing the brand forward the hood will
slide upon the reservoir 8 and permit the
face of the brand to come in contact with the2
