Improvements in and relating to Arc Lamps.
We, JOSEPH MELZER, of 917, Central Avenue, Cleveland, Ohio, U.S.A.,
Electrician, FREDERICK HAFFNER, of 917, Central Avenue; Cleveland, Ohio;
U.S.A., Merchant, and MARTIN KOCH, of 49, Mayflower Street, Cleveland, Ohio,
U.S.A., Merchant, 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:
The primary object of this invention is to provide a combined electric lamp
and electric motor, the motor preferably constructed to drive a fan, whereby a
lamp and a fan are carried by the same hanger or support.
Another object of the present invention is to provide an electric lamp hanger
with a motor surrounding the carbon tube or hanger, and the field and armature
of the motor supported thereby, whereby a lamp and fan are combined in one
to be used separately or together as desired.
Another object of the invention is to provide an electric lamp with a surrounding
motor field, supported thereby, and a motor armature track also supported by
the hanger, the motor armature adapted to receive fan arms, whereby a combined'
fan and lamp, or lamp and motor is provided and combined.
A. further object of the invention is to provide a combined lamp and motor,
and a switch and electric connections between the switch, the motor and the.
lamp, the switch. so constructed that either the lamp or the fan may be used
alone or both at the same time as may be desired.
We attain these objects by the mechanism illustrated in the accompanying
drawing, in which
Fig. 1 is a vertical central sectional view of a combined arc lamp and motor"
embodying the invention.
Fig. 2 is a similar view with parts of the lamp and hanger omitted, showing
a modification in the bearing for the motor armature.
Fig. 3 is a detached enlarged view of the switch lever.
Figure 4 is a diagrammatical view showing the switch and electric connections
between the switch, the motor and the lamp.
Figure 5 is an enlarged sectional view of a portion of the adjusting member for
primarily adjusting the limit of downward movement of the upper carbon of the
lamp.
Referring now to the drawings, 1. indicates a lamp hanger or support and 2 a
tube connected therewith and depending therefrom carrying at its lower end a
plate or dise 3. Surrounding the lower portion of this tube 2 is the winding 4
forming a solenoid, the tube 2 at its lower portion forming the usual hollow
core of the solenoid. Surrounding the upper portion of the tube 2 is the usual
rheostat or resistance for the solenoid 4. Situated within the tube 2 at its lower
portion and surrounded by the solenoid is a brass tube 6 carrying at its lower
end an iron.tube 7 which is the armature of the solenoid. The lower end of the
tube 2 is spread out or enlarged as shown at 8 to form an opening sufficiently

page_text: large to receive the armature 7 and a spring 9 thereabove. The spring has its
upper end engaging the upper end of the enlarged portion 8 of the tube 2 and
its lower end engaging the upper end of the armature 7 whereby the spring 9
normally forces the armature downward. The tube 6 receives the upper carbon 10;
which is adapted under normal conditions to move freely therethrough. The
operation, construction and arrangement of a carbon feeding mechanism will be
described hereinafter.
a
A depending tube 11 has its upper end turned outward as shown at 12 and
this upper portion of the tube 11 is suitably clamped to the plate 3, an insulating
material 14 being placed there between to insulate the tube 11 from the plate 3.
Screwed within the lower end of the tube 11 is the lamp globe socket 15, adapted
to receive the screw threaded socket 16 of the globe 17. The lower end of
this globe 17 is provided with a screw threaded socket 18 adapted to receive
a screw threaded plug 19, and this screw threaded plug 19 is provided with
carbon socket 20 for receiving and supporting the lower carbon 21.
A wire 22 has its upper end electrically connected in any suitable manner with
the globe socket 16 and its lower end similarly connected with the metallic
socket 20 at the lower end of the globe by means of which a current is carried to
the lower carbon 21. A cup-shaped motor support 25 has a screw threaded central
opening 26, which screws externally upon the lower end of the tube 11 and is
supported thereby. The tube 11 in turn is supported by the plate 3 and the plate
in turn by the tube 2 which is supported by the hanger 1, whereby the motor
support is held by the lamp hanger. The side or vertical wall 27 of the cup-shaped
support 25 is provided with the motor field 28 which is arranged in series.
annular motor armature 29 is arranged preferably in series upon a ring 30, the
said ring 30 constructed with the portion 31 to receive the windings of the
armature, and with an upwardly extending annular flange 32 which carries the
commutator 33. Supported by the plate 3 are the commutator brush supports 34.
We here show the commutator rushes consisting of spring actuated copper
pencils or rods 35 which engage the commutator 33, the commutator brushes
being electrically connected in the usual or any desired manner for receiving the
current from the main line.
An
In Figure 1, we show the preferred form of bearings for the motor armature
which is in the form of a ball bearing, the bottom of the cup-shaped support 25.
being provided with a ball race 37 and the ring 30 with a ball race 38, the
balls 39 being situated there between and serving to hold the armature in position
as it rotates around the lamp socket. Projecting from and supported by the
ring 30 are a plurality of arms 40, which are U-shaped in side elevation as
shown having at their outer ends horizontally projecting sockets 41 adapted to
receive the fan arms 42.
It will be noted that the motor field 28 is situated outside of the motor armature,
and preferably in this form though it will be readily conceived that this arrange-
ment may be reversed, the main object being the supporting of the motor field
and armature by the lamp and surrounding it whereby a combined lamp and
motor are provided, the motor preferably for driving a fan.
The plate 3 carries the projecting contacts 45, and the plate 46 at the top of
the solenoid carries an adjustable screw threaded rod 47 insulated from the
plate 46 and through which electrical connection is made through the contact 48
which passes between the contacts 45. This construction is for the purpose of
having the contact 48 between the contacts 45 when the plate 3 has been screwed
to its normal position upon the lower end of the tube 2.
The mechanism for feeding the carbon consists of the solenoid 4, its armature 7,
the spring 9, and a spring depending arm 50 which has its upper end attached
in any suitable manner to the brass tube and its lower portion extending
along parallel with and outside of the armature 7 and its lower end provided with 5
an inwardly projecting clutch portion 51 adapted to engage the carbon 10 below
the armature. This spring arm 50 is provided with an iron portion 53 which

page_text: forms an armature adapted to be attracted by the solenoid armature 7 when
the latter is magnetized. In operation when the current is weakened, the arm 50
will spring outward and release the carbon permitting it to drop and when the
carbon has dropped and the current sufficiently strong the armature 7 will
immediately be drawn upward, and at the same time the arm 50 is attracted
by the armature 7 causing its clutching portion 51 to engage the carbon and
to thereby draw the carbon up against the tension of the spring 9. The tension of
the spring 9 is such as to hold the carbon at a proper point for a proper arc
and thus the carbon is fed as desired. The amount of downward movement
permitted the armature 7 is regulated by the rod 55 which has its lower end
passing through the plate 3 and turned inward under the armature as shown.
The upper end of the rod 55 passes through a tube 56 carried by the plate 46,
and its extremity is screw threaded to receive a thumb nut 58 whereby it may
be raised and lowered for regulating in the first instance the armature fall. The
tube 56 (as illustrated in Figure 5) is provided with a platinum screw 59 engaging
a groove 60 formed in the rod 55 and through which electrical contact is made
as will be readily understood by those skilled in the art. The object of the
groove is to hold the rod against any turning or lateral movement.
The switch lever h is pivoted to the underside of the cup-shaped motor support 25
as illustrated in Fig. 1, and in Figure 3, the specific construction of this lever is
shown. This switch lever is provided with the insulated spring contact f
having two arms as illustrated and adapted to engage the plates which are
insulated one from the other and also from the switch plate 62. The lever is
also provided with a spring actuated contact m and with a second contact 63.
Also carried by the plate 62 are the contact points g, e, and s.
The electrical connections will now be described in a description of the
operation of the switch for either throwing in the circuit the lamp, or the fan
alone, or both. When the fan alone is thrown in, the lever h is moved to carry
the contacts fin engagement with the contacts c, thus making electrical connection
between these contacts and the current is then from the main line to the
wire a, b, contacts c and f, and the wire d to the motor, and p and to the
other pole of the main line. When the lamp alone is to be operated the lever h
is moved to carry the contact 63 to the contact e and the current passes through a,
lever h contacte wire to the clutch through the carbons and to the wire j.
When both the lamp and, fan are in operation the lever his moved still
further in the direction indicated by arrow and the contact f in engagement with
the contacts c, the contact m in engagement with the contact g and the contact 63
in engagement with the contact s when both the fan and motor circuits will be
closed as will be readily understood.
Our invention is especially intended for indoor service, whereby a lamp and
a fan may be combined in one, and either or both used as desired. In the
winter season when the fan is not in service, the fan arms if desired may be
detached from the motor armature arms 40, or they may be left thereon as
desired.
