State of jNew York, have inverted an Improvement in Eleetrie-Are Lmps, 'of which the'followingis' aspeeifieaw earbon holding seeke'ts &each of which has' e project-ing plate or fiange 31:0- which is Con- I neeted-'a link F thati's pivote at its upper end to the T-head G of 'the Slidingtube G', which 'letters ?ateist Ne. .5l4,83,grehted' to ime lfebrnery 1894,'*four-ea`rbon's are rep: resente in 'substantially the semeplene and arrange'i pairs, the' earbons in eaehparir eonverging and stopping 'against "each 'other endthe pa'irs of'earborsheingseparable to draw the are by' the action or the current passing through an electro-magnet,`and in my application Serial Ne. 4995592, filed February :95 1894, 'the four earbons' are represehted as" coming together in thev formof an i nv'e'rt'ed i pyra mid, the two carhois in eaohpair stopping ihe one; against the other as they are'fed down and the' ea rbos being separable bythe aetiojnof themagnet throigh which the cirenit passes.

85 soekets, audone 'em-bon Will not interfere with the carhon will not slip out but will slide down tro-nagnets, the levers, and the dash-pot, the

gradually esthe lower, endtthereof is consumed. e The iframe L,'Figs. 1 and '3, is pivoted at 4:,

5 and the carbon holders KK' are pe'rmanently y i connected therewith and preferabiy insulated i therefrom; and the frame L is swung upon its hinges to'separate; the carbon in the carbon holders K K' from the carbons in the holders E E' by the action of the` electro-magnetas hereinafter described, "and the plate L' is hingedor pivotedat 5, as seen in -Fig.. 2 so that the single'carbon in the'holde'r K is moved ina similar manner. `5 The electro-magnet M isin the main circuit between the binding post G and the^carbon holders E E', so that the current passes from 6 through M and E' and by the carbon holders K' to the bind'in'g* post 7, and the Shunt z o magnet Niset' high-resistatice andisjbetween, the lrindiug posts 6 and 7, and bothof" these magnets M a'ndN 'are provided with sliding 'core's O O' that are connected withsthe lever P, the pivot 8 ofwhich is preferabl'y npon the magnet 'M- as indicated, and-one end of.

the leverP has a connecting r'od `9 to a pis 4 ton in the dash-pot Q which acts to prevent the notion of the magnet cores being too sudden', and there is a lever R pivoted at- 10 and'connected at one end with the core O of the magnet 'M and at the other end' by a screw rod ll 'with the 'fi-ame `L` or plate L'.- It will now be unders tood that the' shunt 'through the-magnet N maintains the electrcfl 3 5 circuit, and the magnetism in N 'acts in the opposite direction to the' magnetism in M, andwhen themaguetisn in M increases' in consequence of the currentpas'sing through the carbon holders and. carbons, the core of 40 the 'magnet M acts to separate the carbons and increase theresistance in the ch-enit:

passingthroigh the magnet M, and the parts areto beTadjusted :by the 'nuts on the screw rod 11, so that the proper .length of arc will be maintained by the relative magnetisn in .the helices M and. N. e

4 In Figs. 2 and 5, I have represent'ed a cut'-` Iout S the helix of whose electro-magnet'isin the main line circuit passing throughthe magnet`M and earbons, and 'the armature 12 closes the circuit through'the Shunt magnet N when the current passing through'the carbons is too great y -By this'improvenent the iamp'is simplifi d 5 5" in its'construction so' as 'to be"compa ,1;i 1

inexpensive and the carbons are easily intro-j duced or replaced, and very little' attention is required in maintaining the 'lamp in the 'most eflicient working condition, and the car 6o` bons coming together as an uverted pyramid,

. 'but little shadow is cast downwardly by any portion of the iamp, and where three carbons are 'made use of the Consumption will i be ieariy uniform if the circuit conn'ections are made in such a manner that the two carbons` 'are connected with the -l binding post, and in consequence of the'arrangeme nt of theelecits motion directly from the core of the magtrolled by the. electro-magnet N acting'upon the lever P in connection with the piston of the dash-potQ to which such lever P is also connected.
