Toall whom it may concern:

Beit known that I, ALLEN WAL'roN of Philadelphia, Pennsylvania, did obtain Letters Patent of the United States. dated 'April 15, 1862, for an Improvement in A iparatus for Mixing Gases, which Letters atent I deem inoperative and invalid by reason of a defective and insiitiieient speeii'eation and I do hereby deelarethe following to be a full, elem', and exact description of the same, reer ence being had to the accompanying drawings, and to the letters of reference marked thereon.'

i y 'iiivention consists of-a ehamberor mixing-reservoir soarranged as to intercept the -con'ti'nuity or uniform diameter of a distributing-pipe, in'to which aira'nd gas are introduced indefinite proportions by a meter or by meters opemting "in unison with each other,

so that the said air ond, 'maybe thorough-1y mixed prior telescopio-g et the burners, 'and so that 'the dames 'from the latter may be brilliant demi bed hereinafter. In order to ensuit ooms ski-nenn um m to make and apply my i'nientirm, I will now {ocecd 'to riesci-ino the manner of carrying il, inlto 'eiiedt l Tn the faceompa'oyirig' drawing, which 'forms oy perf ot' this 's1'veeiatioinik is s 'noelt view offa gas-nretenor which ian English paient was granied to .iseriesGrete hott (firnielz'etts i'nvenion may "said to yconsist of two meters conralined in one exiterior oasin'g, one 'meter boing devoted *to the measuremen't'of illuminating-:gas and bhe other to fthe measurement air, the 'two meters f m'erating in unison with `each other, so thaitthexfeantityof .gas given 'ont by meter wiil iboor indennita pmimrtion fto llhefnirgvei out by `tl`|'e other. i' v Il; is Well lmo'wu -tlr'at 'by'niixiirg )air with `gas generated iro'wn many 'qualities ofeoalfand more especially 'from yresin, V.the 'residmrm of eoallioil frfte'rdistil'l-ation, and -othevrfsubritanees i ne ill um i dating power of ithe fgas is increased. lf this :process of mixing Aair with. gas, Show- -even be "conducted without a 'sifriet Lriiiaird k'to definitie profnrt'ions "dwngeroiis explosion.r`

may 1:2,118112t i In using two meters, orrather a double i meter, according izo Urutchetts patent, l have found that althoughproper proportions i of air and gas are delivered into the distributl ing-pipes from the meters, the flames of the 1 burnersv are liable to Waver or dicker, a result which I believe to be owing to the want; olla 1 thorough adlnixtuieot the air and gas, both i being simultaneously discharged direct from E the meter or meters 'into the ordinary disi tribntingqiipes and continued in an uninternipted course to the burner. in older to remedy thisdefect I plane at any point in the distributingpipe between the meters and the burner a chamber or vessel communicating with and in fact formnga part .of the distributing-pipe.- In the -aeeompanying drawings this chamber, or, as I shall term it, the mixingreser'voir is situated adjacent 1o Grutciiet'ts 'air and gas n .passing together directly into the reservoir through the pipe infami from 'the reservoir io the bumers through the distributing-pipe D. In passing from the meter through vthe pipe B fthe two iiriids are mit, 4co flow Iin independent, or at least; ,partially u'nn-iixed, euri-onus; but tii'e moment they :arrive at the chamber C, which is in edeoi; aythe -di'sfrilyu-ting-pipe, r`an expansion of the Iii-nids takes .piane to an the Acapacity oi' iche elramiser. in fiass'ingg from the la-Lte'r, and on'eniiering tihe distributingpi'pe, however, Aa smifden mnftrnction of v#the two iifuids takes *pinne It is hy 'th'is `exponsion and oon'trmztiion lof the two ll'niids Tin vthe "eliamhw or enlargement of 'tire pipe 'willich causes 'the desired fthoron'gh mimi xture of the iiinids, and which converts as yit were, into =one^fiuid`-t`hngt is, zinlzo gos-Which ,produces a ste'afflyand brilliilnt Aflairn'e alt; the xlmrn'ers. `l prefer to intercept the continuity -ot' ltlre distribeffing-pipe 'from although tlhe Idesired e'eet may be :prpdnoed l by .placing 'the reservoir'at 'any q io'int; vbetween `ie"met.ors -alud 'the burners.
