MEANS FOR PROTECTING ARC LAMP REFLECTORS Filed 001;. 14, 1949 FIG-2 ROBERT M. 'OORL INVENTOR ATTORNEY Patented May 1, 1951 MEANS FOR PROTECTING ARC LAMP REFLECTORS Robert M. Cori, Maumee, Ohio, assignor to The Strong Electric Corporation, Toledo, Ohio, a
corporation of Delaware Application October 14, 1949, Serial No. 121,382
6 Claims.
My invention relates'to arc lamps, and particularly to are lamps comprising a, reflector receiving and projecting the light from the arc, and in which the reflector is in position to be engaged by material dropping from one or both of, the arc electrodes, and the principal object,
of my invention is to provide satisfactory means to intercept such material and thereby prevent the same from injuring the reflector.
In the drawing accompanying this specification and forming a part of this application I Figure 2 is a section on the line 22 of Fig-,
ure 1; and g Figure 3 is an enlarged section through the guard means, on the line 3-3 of Figure 2.
For purposes of illustration I'have indicated in the drawing a lamp 16) comprising a channelshape base member H, a rear end plate 12 and partition i3 supported by the base member II, a top plate it. supported of the end plate I2 and partition 13, and sides It hinged to the respective margins of the top plate I 4.
Supported from the base member H are electrode carriers l5 and H carrying the arc elec trodes is and i9 and one or both reciprocable to provide for consumption of one or both of the electrodes in the operation of the lamp.
Also comprised by the lamp i0 is a reflector 20 constructed and arranged to receive and project the light from the arc, and located in position to be engaged by material dropping from the consumable electrode or electrodes and thereby damaged and injured.
To prevent this result I provide means herein shown as a support 2|, :1. plate 22 carried by the support 2! in position to intercept material dropping from either or both of the electrodes 58 and is, and optionally a receiver 23 constructed and arranged to receive the material intercepted by the plate 22.
In the present embodiment the support 2| comprises a sheet-metal member 24 including a of the intercepting plate 22, and a sheet-metal finger 28 Welded or otherwise suitably secured to the rear of the upstanding section 26 of the member 2i and serving to additionally support and accurately position the plate 22.
With the foregoing the receiver 23 is suitably mounted to the lower portion of the upstanding section 26 of the member 24, for example, by means of hooks on the receiver 23 engagin in slots in the section 25, and the entire assembly is conveniently mounted by means of machine screws 29 traversing the foot section 25 of the member 24 and received in cooperating screw threaded apertures in the bottom section of the base member II.
To avoid undue interference with the reception and projection of the light the plate 22 desirably is formed of glass, and is readily removable to facilitate replacement whenever the surface shall become sufficiently marred to create substantial interference, and to the same purpose the finger 28 is made as thin as is consistent with the necessary strength.
As will be apparent to those skilled in the art, various changes and modifications may be made, without departing from my invention or sacrificing any or all of the advantages thereof, and accordingly my invention is not limited to the particular embodiment herein shown, and I claim as my invention:
1. An arc lamp comprising a consumable electrode, a reflector receiving the light from the arc, said reflector being in a position to be en-.
gaged by material droppin from said electrode, and guard means constructed and arranged to intercept such material and thereby protect said reflector from injury by such material.
2. An arc lamp comprising a consumable electrode, a reflector receiving the light from the arc, said reflector being in a position to be engaged by material dropping from said electrode, a replaceable member adapted to intercept such material and thereby protect said reflector from injury by such material, and means removably supporting said member in position.
3. An arc lamp comprising a consumable electrode, a reflector receiving the light from the arc, said reflector being in a position to be engaged by material dropping form said electrode, and guard means comprising a transparent member constructed andarranged to intercept such material and thereby protect said reflector from injury by such material.
4. An arc lamp comprising a. consumable elec I trode, a reflector receivin the light from the are, said reflector being in a position to be engaged by material dropping from said electrode,
a replaceable transparent member adapted to intercept such material and thereby protect said reflector from injury by such material, and means removably supporting said member in position.
5. An arc lamp comprising a consumable electrode, a reflector receiving the light from the arc, said reflector being in a position to be engaged by material dropping from said electrode, guard means constructed and arranged to intercept such material and thereby protect said reflector from injury by such material, and receiving means constructed and positioned to receive such material from said guard means and to removably retain the same.
6. An arc lamp comprising a consumable electrode, a reflector receiving the light from the arc, said reflector being in a position to be engaged by material dropping from said electrode, a replaceable member adapted to intercept such material and thereby protect said reflector from injury by such material, means removably supporting said member in position, and receiving means constructed and positioned to receive such material from said member and to removably retain the same.
