GEORGE HARRY NASH, of Birmingham in the county of Warwick, Stamper
and Piercer "IMPROVEMENTS IN GLOBE HOLDERS FOR GAS AND OTHER BURNERS
OR LAMPS
"
My invention relates to improvements in globe holders for gas and other burners
or lamps.
In globe holders with arms or clips working on pivots as hitherto constructed
the arms or clips have had to be prepared for the reception of the globe by raising
them in order to bring them within a radius small enough to receive the globe:
Now the object of my improvements is to render this operation unnecessary by
automatically bringing the arms into position for receiving the globe and to allow
of both hands being employed for placing it in position and for removing it from
the holder, whereby the risk of breakage of the globe is much lessened and greater
convenience is afforded. The globe is likewise more securely and easily locked in
position in the holder.
In carrying out my improvements the outer arms or clips which receive the globe
are so hinged to the radial arms or projections of the holder that when the holder
is not in use, that is to say, before the globe is placed therein, the weight of their
inner portions overbalances that of the outer portions which receive the globe.
The upward and downward movement of the hinged arms or clips is limited by
means of suitable stops which are formed thereon and bear upon the radial arms
of the holder which are slotted a certain portion of their length to allow of the said
movement of the hinged arms or clips therein.
The under side of the central portion or boss of the holder is provided with a
locking device consisting of a plate which turns freely on the said boss; the said

page_text: plate is formed with cam shaped projections or eccentrics which, when the plate is
turned, take into corresponding notches in the inner ends of the hinged arms or
clips; a collar or washer serves to keep the locking plate on the boss.
By my improvements when the parts of the globe holder are in their free or
normal position the greater weight of the inner portion of the hinged arms will
have brought the outer portions or clips within a radius small enough to allow the
globe to be placed directly upon them; the weight of the globe pressing down the
said arms causes them to expand outwards until the stops on the inner ends of the
arms bear upon the arms or projections of the body of the holder; the locking
plate is then turned round on the boss of the holder until the cams or projections
thereon enter the hereinbefore described notches in the inner ends of the hinged
arms and thus securely lock the parts in position and effectually secure the
globe-In order to release the globe it is only necessary to turn the locking
plate on the boss in the opposite direction when the globe can be raised from the
holder.
Should the globe not be placed in each clip simultaneously, when the hands are
removed from the globe it will be sure to drop safely into its place in the other
clip or clips.

GEORGE HARRY NASH of Birmingham in the county of Warwick " IMPROVE-
MENTS IN GLOBE HOLDERS FOR GAS AND OTHER BURNERS OR LAMPS"
My invention relates to improvements in globe holders for gas and other burners
or lamps.
In globe holders with arms or clips working on pivots as hitherto constructed the
arms or clips have had to be prepared for the reception of the globe by raising
them in order to bring them within a radius small enough to receive the globe.
Now the object of my improvements is to render this operation unnecessary by so
constructing the globe holder that the arms automatically take the required
position for receiving the globe and to allow of both hands being employed for
placing it in position and for removing it from the holder, whereby the risk of
breakage of the globe is much lessened and greater convenience is afforded. The
globe is likewise more securely and easily locked in position in the holder.
In carrying out my improvements the outer arms or clips which receive the
globe are pivotted to the radial arms or projections of the holder as usual but the
lower or inner portion of the arms or clips are so formed or weighted that when
the holder is not in use, that is to say, before the globe is placed therein, the
weight of their inner portions overbalances that of the outer portions which
receive the globe. The upward and downward movement of the arms or clips is
limited by means of suitable stops which are formed thereon and bear upon the
radial arms of the holder which are slotted a certain portion of their length to
allow of the said movement of the arms or clips therein.
The underside of the central portion or boss of the holder is provided with a
locking device consisting of a plate which turns freely on the said boss; the said
plate is formed with cam shaped projections or eccentrics which, when the plate is
turned, take into corresponding notches in the inner ends of the arms or clips; a
collar or washer serves to keep the locking plate on the boss.
In order to enable my invention to be better understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, is a plan
and figure 2, an elevation of a globe holder constructed according to my invention
the parts being in their free or normal position; figures 3, and 4, plan and elevation
of the globe holder shewing the parts in the position they occupy when holding a
globe; figure 5, is a plan of the underside of figures 3, and 4; figure 6, section on
line A, B, of figure 3, and figure 7, detached view of one of the arms or clips.
Similar letters in all the figures represent similar parts.
a, a, a, are the arms formed with the usual clips b, to receive the globe c; the
arms a, move on pivots or centres d, d, in the outer ends of the radial arms or
projections e, which are slotted and curled over as shewn for that purpose; the
arms a, a, a, are placed on their pivots so that their inner ends overbalance the
outer ends of the said arms so that when free they automatically take the position
shewn in figures 1, and 2, and in dotted lines in figure 6; the part a', of each
arm a, passes through a slot f, in its corresponding radial arm e, the said slots
allowing the arms or clips a, to move on their pivots d, the extent of the inward or
outward movement of the arins a, being limited by the parts k, forming stops coming
against the radial arms e, as shewn in the drawing. g, g¹, is the plate of the
locking device; the said plate is formed with three cam shaped projections or
eccentries g¹, and turns freely on the boss h, of the holder the central portion of the

page_text: boss being drafted or raised to a depth sufficient to allow the locking plate g, to
work freely on the outside thereof and also to allow the washer i, to be placed on
the plate g; then by expanding the end of the tube thus raised or formed into the
inside of the washer the locking plate will be securely held in position; j. j, j, are
notches in the arms a, a, a, to receive the eccentrics g¹, when their plate g, is turned
to fix the arms or clips in position; l, l, l, are projections on the locking plate g, to
allow of the same being easily operated by the fingers.
By this construction when the parts of the globe holder are in their free or
normal position as shewn in figures 1, and 2, the greater weight of the inner portion
of the arms a, will have brought the outer portions or clips b, within a radius small
enough to allow the globe c, to be placed directly upon them, the weight of the
globe c, will then press down the arms a, and will cause them to expand outwards
as shewn in figures 3, 4, 5, and 6, until the stops k, of the inner ends of the arms a,
bear upon the arms or projections e, of the body of the holder; the locking
plate g, g', is then turned round on the boss h, of the holder until the cams or
projections g, thereon enter the notches j, in the inner ends of the arins a, and thus
securely lock the parts in position and effectually secure the globe. In order to
release the globe c, it is only necessary to turn the locking plate g, g', on the boss h,
in the opposite direction to that hereinbefore described when the globe c, can be
raised from the holder.
Should the globe c, not be placed in each clip b, simultaneously, when the hands
are removed from the globe it will be sure to drop safely into its place in the other
clip or clips b,.
Having thus described my said invention and the best means I am acquainted
with for carrying the same into effect what I claim is :-
Firstly. The improved globe holder herein described for gas and other burners
and lamps arranged and operating substantially in the manner and for the
purposes herein before described and represented in the accompanying drawing.
Secondly. Pivotting the arins or clips of globe holders substantially as and for
the purposes herein before described and represented in the accompanying drawing.
Thirdly. The locking plate g, g', for locking the pivotted arms of the globe
holder in position as herein before described and represented in the accompanying
drawing.
