'specification of Letters Patent. Patented Non `24, 1914 Application illed May 19, 1918. Serial'Non'fB. i
T0 all whom-t may concern vBe itknown that I, MARK A. Ross, c1t1zen vof lthe United States, residing at Chicago,
in the county of 'Cook and ate of Illinois, have invented a certain new and useful vImprovement '1n `lillectric-.firc Lamps, of
. whic'h\the following is-a full, clear, concise,
and exact description, reference being fhad to vthe accompan-ing drawings, `forming a part of this'spec fication. v
My invention relates to electric arc lamps. and Vhas for `lits object the I rovision of an improved holder for one o the lamp 'elec- Atrodes.
As I have practised I'mgyyinvention it has been employed for holding the Vlower electrodes of fixed focus arc lam s.
The lamp l'o'fny invei'ltlpn includes 'la bracket upon which an electrode holder is separately secured, this electrode holder including an electrode engaging clamp member and a bracket engaging formation serving to maintain said electrode in alinement with the companion electrode irrespective of the position to which the holder is horizontally turned preparatory to its insertion within the bracket. lThus no arc can be established directlybetween the holder and the electrode companion to that held by the holder.
. My invention also provides means for ad-v justing the electrode held by my holder to compensate for electrode consumption.
Itwill explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which drawing f 1 Figure 1 is a side view illustrating as much of the lamp structure as is necessary toan understanding of the invention. working parts of the lamp structure which are not necessary to an understanding of the invention being omitted; Fig. 2 is a sectional view on line 2 2 of Fig. 1; and Fig. 3 is a sectional view on line 3 3 of Fig. 1.
Like parts are indicated by similar characters of reference throughout the different figures.
In the embodiment of the invention illustrated, the lower electrode 1 is held in position by the device of my invention, the mechanism for positioning the upper electrode 2 forming no novel part of the invention. The upper and lower electrodes are desirably respectively made of carbon and copper -so as ltoenable the lower `one to be consumed slowly.
The vlamp rarney 3 Ihas a horizontal bracket 3 separably'secured thereto, as by means-of screws v5.` "The front end rof this bracket is provided with ac lindrical openlng 6 which is preferably o :uniformdiameter throughout and which opening is coaxial withthe upper electrode 2 as this elecrtrodedependsfrom'the lamp frame 3. The flower electrode .supporting means includes 'apost (whoseflower'endlis ol'setand there 'hasit/wo connected spaced'apart and co-axial tver'tlc'ally 'aimed cylindrical .'formutions v8 Whwhfhave-snugfsliding t within the 'opening 6 so as to be zco-aacialV with fthe'upper electrode 2 irrespective of. the position to Ywhich 'the fp threaded wlng bolt 9 is in threaded engagement with the bracket i'where apertured at 6, the inner end of this bolt projecting into the space between the cylindrical portions 8 to prevent the removalA of the Ypost from the bracket, and permitting a limited range of vertical adjustment for the post and electrode supported thereby.
An electrode clamp member 10 has an l opening through which the electrode 1 and the upper portion ofthe post 7 both pass, an insetting bracket 11' depending from the clamp member 10 and extending below said electrode to support it when such electrode is relieved of clamping pressure. The clamp member 10 and the upper portion of the post 7 engage the electrode upon opposite sides thereof, the portion of the element 10 immediately adjacent the post carrying a clamping threaded wing bolt 12 by means of which the electrode 1 may be firmly clamped between the elements 7 and 10. The post is provided with a number of notches 13 for receiving the inner end. of the clampingr bolt 12 to define definite stages of upward adiustment for the electrode 1 to compensate for ,electrode consumption and to maintain a substantially fixed focus for the arc. A vertical groove 14, terminating sh'ort of the top of post 7, loosely or freely receives the inner end of the screwil, the ungrooved top portion Iof the post preventing the screw 15 from being vertically withdrawn from the post to prevent such an adjustment that would permit the persistence of the are between the upper electrode 2 and the lower electrode holder when ithe lowerelectrode est as :horizontally fturned. Ar
is nearly consumed` rlheqpost 7 and clamp' member I0 are so relatively disposed as to cause the lower electrode to be clamped in alinement with the upper electrode and the post portionsV 8 8 which coperate with the clamp to preserve the alinement of the electrodes irrespective of the position to which said post is turned. llihis result is desirably secured by making the notched upper portion of the post substantially polygonal in cross section snugly to engage the opposite Het sides 16 of the member 10,- to insure the definite engular relationship of the elements 7 and l0 which are of such proportions as finally properly to position the lower electrede when iirmly clamped' in place by the elemp screw 125 While l have herein shown and particularly described the preferred embodiment of my invention l do not 'Wish to be limited to the precise details of construction shown parting from the spirit of my invention but Having thus described v'my Ainvention l claim es 'new'v end desire to secure by Let ters Patent the following :f-
having interengaging formations ,to prevents the clamp from being turned to dierent positions on thepost; and a bracket carried by the clamp and projecting beneath the lower electrode to hold the same in relation to the clamp When not clamped to the post, the post having an odset portion in turning engagementy-Wth the bracket about an axis substantially coincident With the electrode ms., o
in Witness whereof, l hereunto subscribe my name this thirteenth day of May A. D.,
dm3.. as changes may readily be made Without dei Meek le ness.
