STAND-LAMP CONSTRUCTION.
Application filed June 5, 1824. Serial No. 718,044.
My invention relates to stand lamp constructions and more specifically to a stand lamp cluster provided with switches.
One of the objects of my invention is to provide a stand lamp construction which will be simple, durable and efficient.
A further object of my invention isto provide improved supporting means for the lamp contacts, switches and housing.
Further objects will appear from the description and claim.
In the drawings, in which an embodiment of my invention is shown F igure 1 is an axial section of the stand lamp;
Fig. 2 is a top View of the stand lamp, parts being removed to show the interior construction Fig. 3 is a section on the line 33 of Fig. 2; i
Fig. 4 is a section on the line 44 of Fig. 2;
Fig. 5 is a section on the line 55 of Fig. 2; and
Fig. 6 is an unassembled view of the commutator and ratchet.
Referring to the drawings in detail, the construction shown comprises a tubular pedestal 10 which may be of metal tubing affording a passage for the feed wires to the lamp, an insulating base 11 which may be of porcelain or other suitable material, shell and center receptacle contacts 12 and 13 mounted on the insulating base 11, apair of alined switch mechanisms 14 for controlling the two lamps, also mounted on the insulating base, a sheet metal housing 15 for enclosing the base, contacts, switch and a shade-supporting frame 16 supported above the housing 15. For mounting the insulating base 11 on the tubular pedestal 10, a V-shaped metal bracketl'? is provided, the central portion 18 of which is riveted to a bushing 19 screwed into the end of the pedestal 10 and the arm portions 20 of which are clamped against the underside of the insulating base 11. For supporting the upper part of the housing 15 and the shade-sup'- porting frame 16, another V-shaped metal bracket 21 is provided, the arms 22 of which areclamped against the upper side of the insulating base 11. A screw 23 is riveted to the central portion of this upper bracket, the upper part of the casing and the shade-suplower face, respectively,
and center contact in members by means of a metal mechanisms, etc.,-
porting member 16 being clamped on the upper bracket by means of a nut 24 threaded onto the screw 23. For clamping the upper and lower brackets against the upper and of the insulating base, a pair of screws 25 are provided ex tending through registering holes in the bracket and insulating base and provided with clamping nuts 26. The feed wire for both of'the threaded shell contacts 12 is secured to a binding screw 27 threaded into a 'metal stamping 28 to which both of the threaded shell contacts are mechanically and electrically connected by means of screws 29.
Each of the switch mechanisms comprises a spring contact 30, electrically connected with the other binding screw 31, a commu-v tator 32 for making and breaking connection with, respect to the contact 30, a ratchet andchain mechanism 33* for operating the com mutator 32 and a switch frame member 34 in which the commutator 32 is rotatably mounted. This switch frame member 34 is electrically connected with the center contact 13 by means of a rivet member 35 which also serves to hold the switch frame member place on the insulating base. The binding screw 31 is electrically connected with both of the spring contact stamping 36 into which the binding screw 31 is threaded. The spring contact members 30 and the metal stamping 36, are held in place on the insulating base 11 by means of a pair of screws 37 which extend through registering holes in the insulating base and spring contacts and are threaded. into the metal stamping.
For holding the con'unutators 32 in alinement and supporting the ratchet members 38 for oscillating movement, a common switch shaft 39 provided, the ends of which are seated in recesses in the commutators and the central portion of which serves as a support for the ratchet members.
For returning the ratchet member 38 when thus actuated by means of the pull chain 40, a common return spring 41 is provided in the form of a torsion spring, the ends of which are secured to the ratchet members respectively. As the pull chains operate to oscillate the ratchet members in opposite directions, respectively, this common return.
spring will serve for both ratchet members.
Fig. 6 shows details of the commutator and ratchet member. The commutator is provided with ratchet recesses 42 for cooperation with the ratchet tooth 43 on the ratchet member 38. This ratchet member may be a sheet metal stamping having a chain-securing lu 4A to which the end of the chain 40 is D a u a secured and a chain rail portion 45 over which the chain runs.
The circuit is from the binding screw 31 through the metal conductor 36, spring 30,
In witness whereof, I have hereunto subscribed my name.
