7 Claims.
This invention relates more particularly to im
provements in the ‘pivotal connections for the
carrying bails or handles of tubular lanterns.
The usual tubular lantern is made with up
right frame or air tubes at opposite sides of the
lantern through which air for combustion is sup
plied to the lantern burner, and as commonly
5
constructed, these air tubes have inbent or in
wardly extending upper portions connected to a
10 shell or part at the top of the lantern frame and
inbent or inwardly extending lower portions con
nected with an air chamber wall or part at the
lower portion of the lantern frame. Ordinarily,
the handles or wire bails for carrying the lan
15 terns are pivotally connected to the upper por-i'
tions of the air tubes by hooking the bent or
hooked lower ends of the legs of the bail into
holes in the outer side wallportions of the air
tubes. The balls are commonly made of relative
ly stiff or spring wire, and their pivot hooks are
so shaped as to normally prevent accidental or
unintentional disengagement of the ends of the
bail from the pivot holes. However, the bails fre
quently become deformed or bent out of their
25 original shape in the handling and use of the lan
terns, particularly if the bail wire is relatively
soft or pliable, or the pivot holes in the walls of
the tubes become enlarged by wear, with result
ing inconvenience or damage to the lanterns, or
3,0 their loss. In the use of such lanterns on motor
trucks, on the rear end or other portion of which
they may be hung by their bails, breakageand
loss of the lanterns, because of the bails becoming
detached, due to vibrations of the moving trucks,
35 are so frequent as to be a serious loss or objec-v
tion.
One object of my invention is to provide a piv
' otal connection for the bails or handles of tubu
lar lanterns which will reliably prevent uninten

Describing ?rst the embodiment of the inven 25
tion illustrated in Figs. 1-6 of the drawing, the
lantern, with the exception of the construction of
the pivotal connections for the bail, is of usual
and well known tubular lantern construction.
The frame or air tubes I2 at opposite sides of the 30
lantern have inbent or inwardly extending upper
ends I3 which are ?xedly connected to the side
walls of the air chamber shell H! at the top of
the lantern frame, and inwardly extending or in
bent lower ends l5, which are rigidly connected 35
to the wall iii of the air chamber at the top of
the oil fount and surrounding the lantern burner.
The wire handle or bail I‘! of the lantern strad
dles the upper end of the lantern frame, and the
40 tional disconnection of the bail from the lantern. ' legs of the bail are provided with inbent pivot 40
Other objects of the invention are to provide
an improved pivotal connection for the bails or
handles of tubular lanterns, which is of simple
_ and inexpensive but strong and durable construc
as u
tion, and will prevent unintentional disconnec
tion of the bails from the lanterns; which is con
structed so that the bail will be releasably re
tained in either or both of its upright carrying
and inoperative folded positions; and which has
the other features of improvement and advan

claims.

ends l8, each of which extends transversely
through the adjacent air tube l2 through holes
in the opposite or outer and inner wall portions’
of the tube. The bail pivots are prevented from
disconnection from their pivot holes or bearings
in the air tubes by suitable securing means at
the inner ends of the pivots. For this purpose,
the protruding inner ends of the pivots can be
swaged, as shown at I9 in the drawing, bent up
wardly, or provided with cotter pins or other
suitable means which cannot pass through the
pivot holes or bearings and thus prevent the piv
ots from being pulled out of their bearings or
pivot holes.
In tubular lanterns as heretofore commonly 55

the possibility, of the disconnection of the pivots

through a hole in a single thin wall portion of the
55 tube;
Preferably the pivot holes in the air tubes are

40 ed in Figs. 10 and 11, a long bearing eyelet‘ or
bushing 20' is shown extending transversely
through each air tube with the ends of the'bush
ing in the holes in the inner and outerwall
portions of the tube, and being secured therein,
451 as by flanging the ends of the bushing 20, over
the edgesof the holes in the wall of the tube.
These long bushings'not only provide extended
bearings for the bail pivots but also connect the
inner and outer wall portions of the air tubes
and thus brace and strengthen the tubes at the
pivotal connections for the bail.

As clearly shown in the drawing, the axesof the
bail pivots I8‘ are not coincident with the axes
of the bearings for the pivots, but are disposed
at an angle or inclination thereto. For instance,
