In my invention I have produced, a lamp whiel i,`wl1ile it is without clock-work and delii cate points, is quite as sensitive as any lamp -heretofore made, nnd'alsokeepsthe are nlways infocus, as it feeds both-of4 the carbonsexatly in proportion to Athe consumption of ,The accompanying drawing isa side eleva` tion-of my invention, in which Arepresents the positivecar'bon carrier, 13, the negative# carbon carrier; C, a blockV secured to carrier or rod B, and provided with a pulley, D; E,-

The loperatiinr of this lamp is as lollows:
The'carhons being` seeuredto lthe carriers and B, andthe wires of -a strong source of elec! trieit-yproperly connected, the top (posi tive) carbon mayube allowed to slide downward un; -til it touches and makes electrical contact with the lowerlnegative) carbon. Vhen the' circuit isthus establishedthe current passes' through the helix R R. This excites magneti ism int/he core M and draws -it downward wi th thelink N and levers Ol and P, also the mtcliet G,ia ck I, and negativecarbon carrier B. Thisdownward movementof the ilegaltive-carbon carrier'draw's the cordJ and raises the positiveearbon carrier A a corresponding until so much-of the carbon has been consumed 'that the ratchet Gis moved bevond the reach of pawl II. Then the ratchet urns upon its axis, and, .by allowing the 'negativer-carbon carrierto rise, will so 4slacken thecord J that the positive-carbon carrier can fall. As the carbons approach eachother the are is shortened-"fand the magnet-ism increased, 'This 1 the pin and as the pull of the rack I'is balanced 4move' Athe ratchet downward 'snciently to.
current ischanged. The link-T may also be to increase or dixninishits leverage, and to draws down the core M, and with it all its conncctions,nnti1. the ratchet is again held stationary by the pawl H. Should the carbons approach to'o near leach other, the increased magnetism draws the core still fartherinto the helix, as it ,will be seen that the pawl H is free to move downwar `with the ratchet.
-On the top side of the lever P, and near its fnlcrum V, is secured a small spring, c', the strength of vwhich is nearly equal to the tup;v ward pull of the rack I. When the stress is all upward, this spring is compressed; but 'when the ratchet has moved `upward away from the pawl until it is free to turn, then the spring i will throw the end of the lever P downr ward, and with it ratchet G, causing it to catch on the tooth next following the one liberated.
It will he seen that there is lost motion all' lowc'd at fnlcrum `V,the hole being larger than by spring i, it follows that any 'slight relaxation of this pull, which must o'ccur in the liberationdof the ratchet, must enable. the spring to.
catch the next succeedingy tooth on the pawl. The length of thearcmay be regulated by the nut l). The 'tension of thespring d has to he changed as the electro-motive force of the lchanged to give-the core more 'or less. travel,
adapt it 'to strong or weak currents of elec tricity.- By the axrangement ofthe levers as snoivnJ am engahled to make the work o light on the core that very little change in the elec tro-motive force is required to' vmore the carbons.A Y
