THOMAS B. OWENS, OF MARSHALL, TEXAS.
LOCOMOTIVE-H EAD LIG HT.
SPECIFICATION forming part of Letters Patent No. 496,276, dated April 25, 1893.
Application filed October 18, 1892. Serial No, 449,213. (No model,)To all whom it 7neay concern:
Be it known that I, THOMAS B. OWENS, a resi-
dent of Marshall, in the county of Harrison
and State of Texas, have invented certain new
5 and usefulImprovements in Locomotive Head-
lights; and I do hereby declare the following
to be a full, clear, and exact description of the
invention, such as will enable others skilled
in the art to which it pertains to make and use
zo the same.
The invention relates to locomotive head
lights and is applicable to so-called independ-
ent reservoir lamps. The conduit by which
the reservoirand burnercommunicate is liable
I5 tobe obstructed with sediment which not only
interferes with the suitable flow of oil but cor-
rodes the metal and necessitates repairs.
The object of the invention is to provide a
convenient and inexpensive receptacle for
20 such sediment which will permit of its easy
removal, and it consists in the construction
hereinafter described.
Figure 1 is a side elevation partly in section.
Fig. 2 is a partial rear elevation. Fig. 3 is a
25 cross section of the oil pipe and receptacle on
the line 3-3 of Fig. 1.
Numeral 1 denotes an Argand burner pro-
vided with a wick raiser both of usual form
and 2 is an oil reservoir.
30 3 denotes a pipe or conduit by which the
interior of the reservoir and the wick space
of the burner communicate. The reservoir
mouth of this pipe is provided with a valve
seat 4, and 5 is a valve adapted to hermetically
35 close it when desired. The valve stem has a
screw threaded connection with a plug 6 se-
cured to a frusto-conical sleeve or boss 7 made
fast on the top of the reservoir.
8 is a milled head of the valve stem situated
40 below the arched reflector-support 9.
10 is an approximately frusto-conical sleeve
surrounding the vertical member of the pipe 3
and rigidly secured both to the pipe and reser-
voir to strengthen their connection and 11 is a
45 brace. The under side of the horizontal mem-
ber of the pipe 3 is cut away and adjacent to
the metal edges surrounding the opening thus
made is secured a.flattened approximately
oblique frusto-conical receptacle 12 having
50 a tubular mouth 13 adapted to receive a screwplug 14. The receptacle 12 is preferably se-
cured both to the pipe and to the exterior of
the wick tube by soldering or otherwise sub-
stantially in the manner illustrated, whereby
the connection of the pipe and tube is strength- 55
ened.
The opening in the pipe covered by the re-
ceptacle extends by preference to the wick
tube the exterior of the outer wick being in
practice exposed directly to the oil in the pipe 60
3 and in receptacle 12 and the sediment in
such oil being free to settle and fall down the
inclined bottom of the receptacle from which
it can be removed at will through the tubu-
lar discharging mouth whenever the screw 65
plug is taken out. But prior to such opera-
tion the valve 5 will be tightly closed upon its
seat if there is any oil in the reservoir.
I am aware that sediment receptacles have
been attached to vapor burners and to pipes 70
adapted to supply oilto burners and I do not
claim broadly such devices but only the con-
struction herein pointed out. My receptacle
has a length much greater than the diameter
of the supply pipe and communicates with 75
said pipe by means of a long slot which to-
gether with the receptacle communicates with
the wick tube and it is provided with an in-
clined bottom that guides sediment from the
interior of the wick tube to the laterally situ- 80
ated openingclosedby a removablescrew plug.
This construction gives enlarged capacity to
the receptacle, adapts it to receive sediment
from the wick tube and also to drain the same
and strengthens the connection between the 85
pipe and tube. The connection between the
pipe and reservoir is strengthened by the
sleeve and brace before described the whole
construction giving increased capacity for
separating sediment and at the same time 90
bracing and firmly joining the parts. The
latter function is secured by fastening both
the slotted pipe and receptacle to the wick
tube as well as by the use of a brace and flar-
ing sleeve. This construction is of impor- 95
tance because it constitutes the sole support
of the oil reservoir and reflector. The holder
for the latter is arched to provide suitably for
the head of the valve stem which is protected
thereby. The valve has a raised seat imme- 1oo
