We, SALOMON FALK, of 83, Farringdon Road, in the County of London, Manufacturer,
and ALFRED ZEMPLINER, of Anhofstrasse 76, Vienna, in the Empire of Austria, Manager
of Factory, do hereby declare the nature of this invention to be as follows

This invention relates to hanging lamps and comprises a novel construction of the
fraine or holder in which the lamp proper is suspended and of the suspension
pieces whereby the parts can be fitted together without the use of screws, bolts or
the like.

According to the said invention the lamp holder or frame has a series of arms at
the lower ends of which is fixed' a bowl for holding the lamp reservoir and at the
upper ends a ring for carrying the lamp shade. On the bowl are formed bifurcated
lugs and on the lower ends of the arms are pivot pins which rest on these lugs and a stop
which limits the outward pivotal movement of the arm's relatively with the said bow!:
In the said ring are holes or slots which 'receive lugs on the upper ends of the arms
and hold the latter distended so that the said arms cannot be turned upon their
pivots to disconnect them from the bowl.
The head of the lamp which is attached to the suspension hook has recesses formed
in it to receive the rollers over which the usual suspension chains pass, the said
rollers having cast axles which fit into bearings in the said' recesses. The eye for
attachment to the suspension hook is provided with 'a shank and button, and in the
centre of the head is a slot through which the eye is passed from the underside of
the head the button preventing the shank from being pulled through the slot and
carrying the weight. On the shank are wings which prevent the eye from passing
through the slot until the shank has been turned to bring the wings opposite to
the slot.
The casing for the balance weight is divided vertically the two parts being formed
so that the edge of one fits into the other a ring on the top of the said casing holding
the two parts together. At the inner bottom side of each part of the casing is a
projection the projections of the two parts when placed together forming a 'stud-upon
which the balance weight having a corresponding hole rests. The balance weight
thus serves for assisting to hold the two parts of the balance weight casing together:

page_text: of Factory, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:―
This invention relates to hanging-lamps and comprises a novel construction of
the frame or holder in which the lamp proper is suspended and of the suspension
pieces whereby the parts can be fitted together without the use of screws, bolts or
the like.
According to the said invention the lamp holder or frame has a series of arms at
the lower ends of which is fixed a bowl for holding the lamp reservoir and at the
upper ends a ring for carrying the lamp shade. On the bowl are formed bifurcated
lugs and on the lower ends of the arms are pivot pins which rest on these lugs and
a stop which limits the outward pivotal movement of the arms relatively with the
said bowl. In the said ring are holes or slots which receive lugs on the upper ends of
the arms and hold the latter distended so that they cannot be turned upon their
pivots to disconnect them from the bowl.
The head of the lamp which is attached to the suspension hook has recesses formed
in it to receive the rollers over which the usual suspension chains pass, the said rollers
having cast axles which fit into bearings in the said recesses. The eye for attachment
to the suspension hook is provided with a shank and button, and in the centre of the
head is a slot through which the eye is passed from the underside of the head
the button preventing the shank from being pulled through the slot and carrying
the weight. On the shank are wings which prevent the eye from passing through the
slot until the shank has been turned to bring the wings opposite to the slot.
The casing for the balance weight is divided vertically the two parts being formed
so that the edge of one fits into the other a ring on the top of the said casing holding
the two parts together. At the inner bottom side of each part of the casing is a
projection the projections of the two parts when placed together forming a stud upon
which the balance weight having a corresponding hole rests. The balance weight
thus serves for assisting to hold the two parts of the balance weight casing together.
To enable our invention to be fully understood we will describe it by reference to
the accompanying drawings, in which :-
Figure 1 is a sectional elevation of the ring, one arm and bowl shewing the manner
in which these parts are held together;
Figure 2 is a plan of the bowl:
Figure 3 is an edge view of the arm:
Figure 4 is a plan of a portion of the ring:
Figure 5 is a sectional elevation of the head of the lamp and of the suspension
hook:
Figure 6 is an elevation of the suspension hook at right angles to Figure 5 shewing
it in position in the head of the lamp:
Figure 7 is a plan of the head of the lamp with one roller in position:
Figure 8 is a plan of the balance weight:
Figure 9 is a vertical section thereof; and,
Figure 10 is a section on the line 10-10 Figure 9.
a, Figures 1 and 2, is the bowl for carrying the lamp reservoir the said bowl being
provided with a number (in the drawing three) of bifurcated lugs b and c is the ring
for carrying the lamp shade the said ring being provided with a number of holes or
slots d. e is one of the arms by means of which the bowl a and ring c are secured
together without the employment of screw, bolts or the like.
ff are the pivot pins formed on the lower part of each arme the said pins projecting
on either side of a central rib g adapted to fit in the space between the legs of the
bifurcated lugs b of the bowl a. Each rib g is provided with lateral extensions g¹
which are so curved that they allow the legs of the bifurcated lugs b to be passed
under the pivot pins f to a sufficient extent but which limit the outward movement
of the upper ends of the arms e relatively with the bowl so that they thereby form
a stop.

page_text: h is the lug on the upper end of the arm e which lug is adapted to pass through
one of the holes d in the ring e so that the said ring can hold the arms extended and
thus prevent the lugs b from being disengaged from the pivot pins f. Each arm e is
provided immediately beneath the lug h with a plate or support i on which the
ring c rests.
is the head of the lamp and k, k, k the recesses formed therein for receiving the
rollers the said rollers being provided with axles ¹ which rest in bearings in the
said recesses k, as shewn clearly in Figures 5 and 7, m is the central slot provided in
the head j.
n is the shank and o the button of the eye for attaching the head of the lamp to a
suspension hook the said shank n being provided with lateral wings p which prevent
the eye from passing through the slot m in the head j of the lamp until the shank is
turned so as to bring the said wings p opposite the slot m.
9, 9 are the two halves or parts of the casing for holding the balance weight r. One
of the parts or halves q is formed with lateral flanges which fit over the edges of the
other half and each part q is formed with an upwardly projecting plug or
projection at its lower end, the said projections when the two parts are placed
together forming a central plug or stud which fits into the hole in the bottom of
the weight which thus assists in holding the two parts of the casing together, the
two halves q, q being held in position at their upper ends by the rings which fits
under the projections s¹ upon the said upper ends of the halves q, q of the casing.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a hanging lamp forming the lamp holder, the head and the balance weight
of parts so constructed and arranged that the whole can be fitted together without the
employment of screws, bolts or the like, substantially as described and illustrated in
the accompanying drawings.
2. The combination and arrangement of parts forming the improved fittings for
hanging-lamps herein before described and illustrated in the accompanying drawings.
