IMPROVEMENTS IN TUBULAR Lanterns
Year: 1883

page_text: LETTERS PATENT to Thomas Phillips, of Orillia, in the County of Simcoe,
in the Province of Ontario, in the dominion of Canada for an Invention of
"IMPROVEMENTS IN TUBULAR Lanterns"
PROVISIONAL SPECIFICATION left by the said Thomas Phillips at the
Office of the Commissioners of Patents on the 29th December 1883.
THOMAS PHILLIPS, of Orillia, in the county of Simcoe, in the Province of
Ontario, in the Dominion of Canada, IMPROVEMENTS IN TUBULAR LANTERNS
My invention relates to what are technically known as tubular lanterns and has
for its objects, first, to construct an improved hinging device by which the upper
portion of the lantern may be swung back clear of the burner, so as to afford ready
access to the latter for the purpose of trimming and lighting the wick; also to
provide a moveable guard to allow of the ready removal of the globe if desired.
My improved hinging device consists of two short trunk tubes one attached to
each side of the burner case opposite each other and forming a straight line. The
ends of these trunks have each secured upon them a flat arm or plate bracket
projecting upwardly and rearwardly. The lower ends of the upper or main tubes
are each provided with a similar arm or bracket, the face of each being made flush
with the tube to form a face joint between the trunk and the tube having a free
passage. Each pair of these brackets are pivoted together at the upper projecting
end so as to swing from said pivot as a centre. A portion of the lower edge of
one bracket on each side is bent over at a right angle to form a stup for the other
bracket when the upper portion of the lantern is upright or in its normal position.
The upper tubes carry a perforated plate or disk having a suitable rim and secured
to the tubes by wire brackets, said plate supporting the globe which is pressed upon
the disk by a suitable spring attachment at the top
A flexible latch is secured to the perforated globe disk to engage a pin on the
burner case, or another suitable fastening device may be employed to securely hold
the lamp base and globe in their normal position.
The tubes are further provided with wire guards for the protection of the globe.
These consist of two short parallel wires some distance apart and the rear ones
permanently secured to the tubes. The front pair is hinged at one end and
provided with a pin engaging an eye on the tube, at the other end the flexibility
of the wire allowing the pin to be lifted in or out of the eye, and thus permitting
it to be swung back to allow of the removal of the globe,

the said Thomas Phillips in the Patent Office on the 28th June 1884.
THOMAS PHILLIPS of Orillia in the County of Simcoe in the Province of
Ontario in the Dominion of Canada "IMPROVEMENTS IN TUBULAR LANTERNS"
My improvements consist mainly in hinging the tubes from the projecting arm
of a bracket which enables the entire upper portion of the lantern to swing back
so as to allow free access to the burner for the purpose of trimming and lighting;
also in the construction of the guard, one half of which is hinged and swings back
to allow of the free removal of the globe.
Figure 1. is a front elevation of my improved lantern the top being partly in
section.
with a screw cap a.
Figure 2. is a side elevation of the same showing the upper portion swung back.
A, is the base or oil cistern of the lantern to which the burner B, is attached in
the usual manner. The base has the usual opening for filling the cistern provided
C, C, are the two tubes carrying the whole of the upper part
of the lantern, and C, C¹, are the two short trunks of the tube attached to the
lower part of the burner case, The tube C, and' trunk C¹, are jointed together by
two plates C3 and C³ forming a face joint having a free passage. These plates are
rigidly secured to the tube and trunk respectively and form upwardly projecting
arms or brackets pivoted together by a pin C, at their upper or projecting end, the
plate or bracket C2 having its lower forward edge c³ cropped over the edge of the
plate C³ at a right angle to form a stop when brought face to face and the upper
portion of the lantern in its upright or normal position. D, is a perforated disk
with a suitable rim which supports the globe and is secured by the wires d to the
tubes C, being further provided with a flexible latch plate d, which engages a
pin d² on the burner case.
The globe E, is held down upon the disk D, by a wire hoop f encircling the
upper rim of the globe and having upwardly extending arms passing through a
plate in the hood of the lantern and projecting at the top where a ring or other
suitable handle is attached, a spiral spring F, being inserted between the upper
plate of the hood and the laterally projecting arms of the hoop f for the purpose
of keeping the hoop in position. G, G' are the guards, the rear one G¹ of which is
permanently secured, while the front one G, is hinged at g to the tube and provided
at the other end with a pin g¹ engaging into a tubular eye gª secured to the other
tube. The guard being of wire is sufficiently flexible to allow of the pin g¹ being
lifted at one side by means of the handle g³ out of the tubular eye as shown in
dotted lines in Figure 1. and may be swung back to remove the globe
I claim as my invention
1 The combination of the tube C and trunk C₁ provided with upwardly and
rearwardly projecting face plates C2, C3, pivoted at their upper end to form a face
joint, the said trunk C³, being secured to the burner case, the tubes C, carrying the
entire upper part of the lantern and provided with a fixed guard G' and hinged
guard G and latch d', as set forth for the purpose described.
2. The hinged face joint of the trunk and tube consisting of two face plate
brackets C C³ rigidly secured to the tubes and trunks respectively projecting
upwardly and rearwardly and pivoted at their upper end, the moveable arm C
having the lower front edge c³ cropped to form a stop.

page_text: 3. The guard G hinged at one end to g, the tube C³ and having at the other end a
pin g' and handle g₁ engaging a tubular eye g³, in combination with the tubes C.
all substantially as described and for the purposes set forth.
In witness whereof, I, the said Thomas Phillips, have hereunto set my hand
and seal this fourth day of June in the year of our Lord One thousand eight
hundred and eighty four.
