Bc it known that l', Joon gl". TONKIN, of ewego, in tlloooilnty ol'I (lewego, in the State ol blow York, have iro/onted new and useful llmorovemoiite in Stoom-Boilers, of which tbe following, token in connection with theV nooo!:annoying drawing-e, ie n, lull, oleor, and emot descrlri'iton.

` This invention relates to tlie clase of steam i boilers which ore termed nf'ateitnbe boil# ere, and it liao more pzntlcnlzn reference to the style of bollore shown ln roy' Lettere Patent No. 772,071, dated lllctober 1l, ,1.904.

The, object oftlle preaent invention is to more eileotuallyseparate the Water :from the steam in generating seid steam and to otl1er- Wise inoreoee'tlie elloienoy' ofthe boiler; and 'to that end the invention oonsiete of a novel construction and oombination of auxiliary devices applied to tbe boiler, as hereinafter described ond ao illustrated in tbe aecomnanying drnwnge, in` Wl1iol1- Figure l ie a vortice] `lOngitndinal section nl'eboilerembodyinginyinlprovelnents. Fig. n

2 is a top plan View' oli the seine, and Fig'. 3 ie a transverse eection on the line e; in. Fig-g. l. ln the said drawings, A. and A designate two Waterdege, which extend aoroestlie ende viront end portion of the boiler, and C ie tbe of tbe boiler ond are connected with eacli other by tbelonggrtndlnnl Water-tubes no,

which are inclined from tbe front Water-leg- A to the roar Watenleg A. B denotes tlie lirebon, Wlnob under the fire-flue, which entende from the lireboit to 4the rear end ot tbe boiler.

The front Watcr-leg llt, l prefer to lorrn of a deptb to extend across the front of tbe rebox `to expose said woterfleg to tbe fire, and thus increase` tbe l lioatlngeurlnce ol the boiler/While tbe roar' waterdog il extends only slightly below the lower row of Water-` tnboe (tand .le support-eden tlleeml wall l). l preferablynnterpoee rollers c c between the 'bottom of tbe rear Materie/fand top of the o o to expand and Wall D to allow tbetubce Without stroming contract longitudinally them.'

'I The two drinne F and F I corresponding planes and at tion above the Water-legs to collect thestearn l generated in the boiler proper., I the pressure of the steam in the two drums, I' i enlploy` an eqnalizlng-pipe P, which 1is *oonl recte( at opposite ends to the upper parts 'of ,l t io i T l.`l1e crown or too cover L oftheboiler "itt` inverted -Trt l,

To efiectually separate the steam from the Water of the boiler, I place in the rear drum F a {ir}T plate L', which l preferably incline from over the end of the pipe P, as shown in Fig. l, and between this dry plate and steam-outlet 0 I place the dry pipe leg and Connecting snit n, which conducts the steam `to said outlet. The pipes Z and l) are provided with expension-plate joints Z to relieve seid pipes from strain'inoident to expansion and contraction thereof.

' What I claim as, my invention is# A Water-'tube boiler consisting oic weiter` legs extending across the ends of the boiler, longitudinal Weter-tnbes disoosed inclined from the front Water-lee 'to tie rear Waterwator-legs, drums neoted to tbe top of the rear drum as set forth.
