Taal?, whom it may concern:
13e it known that I, JOSEPH MELZER, a citi- '/.en of the United States, residing at Cleveland, inthe county of Cuyahoga and State of Ohio, have invented new and useful Improvements in a Combined Electric-Arc Lamp and Fan, of which the following is a specification.
My invention relates to improvements in combined electric-arc lamps and fans, and pertains to an electric lamp provided with a surrounding motor for driving,preferably, a fan, all of which will be full y described hercinafter and particularly pointed out in the claims.
The primary object of my invention is to provide a combined electric lam p 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 my 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. i
Another object of my invention is to provide an electric lamp with a surrounding motor-iield supported thereby and a motorarmature track also supported by the hanger, the motor-armature adapted to receive fana-rms, whereby a combined fan and lamp or lamp and motor is provided and combined.
A further object of my 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.
. In the accompanying drawings, Figure 1 is a vertical central sectional view of a combined arc-lamp and motor embodying my 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 switchlever. Fig. 4 is a diagrammatical view showing the switch and electric connections between the switch, the motor, and the lamp.
Fig. 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 disk 3. Surrounding the lower portion of this tube 2 is the winding 4,' forming the magnet of 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 Ll. Situated within the tube 2, at its lower portion, and surrounded by the solenoid is a brass tube (3, 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 suflicient-ly 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 G receives the upper carbon 10, which is adapted under norm al conditions to move freely therethrough. 'lhe operation, construction, and arrangement of a carbon-feeding mechanism will be described hereinafter.
A depending tube 11 has its upper end turned outward, as shown at 12, and this upper portion of the tube 1l is suitably clamped to the plate 3, an insulating material 14 being placed therebetween to insulate the tube 11 from the plate 3. Screwed within the lower end of the tube 1l is the lamp-globe socket 15, adapted to receive the screwthreaded socket 16 of the globe 17. The lower end of this globe 17 is provided with a screw-threaded socket 1S, adapted to receive a screw-threaded plug 19, and this screwthreaded plug 19 is provided with a carbon- 95 ICO socket 2O at the lower end of the globe, by means ot' which a current is carried to the lower carbon 2l. A cup-shaped motor-support 25 has a screw-threaded central opening 2G, which screws externally upon the lower end of the tube ll and is supported thereby. The tube ll in turn is supported by the plate 3 and the plate in turn by the tube 2, which is supported by the hanger l, whereby the motor-support is held by the lamp-hanger. The side or vertical wall 27 of the cup-shaped support Q5 is provided with the motor-held 2S, which is arranged in series. An annular motor-armature 29 is arranged, preferably, in series upon a ring 30, the said ring 30 constructed with the portion Sl to receive the windings of the armature and with an upwardly-extending annular ange 32, which carries the comm utator Supported by the plate are the commutator-brush supports 34. l here show the commutaton brushes consisting of spring-actuated copper pencils or rods 35, which engage the commutator 33, the comn'ultator-brushes being' electrically connected in the usual or any desired manner for receiving the current from the main line.
In Fig. l I show thepreferred form of bearings for the motor-armature, which is in the form of a ball-bearing, the bottom oi' the cupsllaped support 25 being provided with a ballrace' 257 and the ring 50 with a ball-race 3S, the balls 3*.) being situated therebetween 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 outerendshorizontally-prejecting sockets 4l, adapted to receive the fan-arms 42.
lt will be noted that the motor-field 2S is situated outside of the motor-armatures, and preferably in this form, though it will be readily conceived that this arrangement 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.
'lhe plate 3 carries the projecting contacts 45, and the plate to at the top ofthe solenoid carries an adjustable screw-threaded rod 47, insulated from the plate t6 and through which electricalconnection is made through the contact 4S, which passes between the contacts t5. This construction is for the purpose of having the contact t8 between the contacts t5 when the plate f3 has been screwed to its normal position upon the lower end of the tube 2.
The mechanism for feeding the carbon consisls of the solenoid et, its armature 7, the spring than d a spring dependingarm 50, which has its upper end attached in any suitable manner to the brass tube 0 and its lower portion extending along parallel with and outside of the armature Zand its lower end provided with an inwardly-projecting clutch portion 5l, adapted to engage the carbon lO below the armature. This spring-arm 50is provided with an iron portion 53, which forms an armature adapted to be attracted bythe solenoid-armature 7 when the latter is magnetized. In operation when the eurrentis wea-lt` cned 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 5l to engage the carbon and to thereby draw the carbon up against the tension of the spring il. The tension of the sprinOr 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 sl-G, and its extremity is screw-threaded to receive a thumb-nut 5S, whereby it may be raised and lowered for regulating in the first instance the armature fall. rlhe tube 56, as illustrated in Fig. 5, is provided with a platinum screw 59, engaging a groove (SO, formed in the rod 55 and through whichelectrical contact is made, as will be readily understood by those skilledin the art. The object of the groove is to hold the rod against any turning or lateral movement..
The switch-lever 71y is pivoted to the under side of the cup-shaped motor-support 25, as illust ated in Fig. l, and in Fig. Sthe specific construction of this lever is shown. This switch-lever is provided with the insulated spring-contactly, having two arms, as illustrated, and adapted to engage the plates c, which are insulated one from the other ,and also from the switch-plate U2. The lever is also provided with a spring-actuated contact ml and with a second contact Also carried by the plate G2 are the contact-points g, e, and s.
The electrical connections will now be de scribed in a description of the operation of the switch for either throwing in the circuit the lamp, or the fan alone, or both. lVhen the fau alone is thrown in, the lever h is moved to carry the contacts f in engagementwith the contacts c, thus making electrical connection between these contacts, and the eurrent is then from the main line to the wire u b, contacts c and f, and the wire d to the motor and p and j to the other pole of the main line. lVhen the lamp alone is to be operated, the lever 7L is moved to carry the contact G3 to the contact e, and the current passes through o, lever 7i, contact e, wire to the clutch, through the carbons, and to the wire j. lVhen both the lamp and fan are in operation, the lever 7L is moved still farther IOO llO
in the direction indicated by arrow and the y 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.
My invention is especially intended for indoor service, whereby a lam-p 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.
