 ami sto\cs, and Iht'ir instrument, ma- 

 tbinf. or apparatus Cor supplying jjratt's 

 »Hrl stoves with U\c\, is to produce « 

 inorc perfect combiisiiou of the fuel 

 tlmn is eficcled in the p;ra(cs and stoves 

 »)f flic nsnal coiisfn:ction ; wliicli is ac- 

 rnmplished by the inserting or tlepnsi- 

 tiiig of fresh coals, or iinbiirnt fuel, into 

 fir i:udcr t!ie bottom of a Crc previously 

 lighted and burning ; they prepare Ihcir 

 grate orslovc for the reception of fresh 

 coals or nubnrnt fisel, by making the 

 lioftom liars: or gratings, which support 

 flio liuviiing fuel, quite flat and level; 

 they also place under the said bars or 

 jrratiiigs, a pl^te for Uic fnirpose of oeea- 

 yionaliy ohstnieting tiie pa«:sHgc of fliio 

 coals or eioiVers hetwern t!ic said bars 

 cr gratings; wliich plate tiiey eausf to 

 rli'le av\'ay, or otherwise to he Ining 

 w^itii hinges, and fall away wiienevcr it 

 may be tiioiight necessary for the ad- 

 mission of fresh air, up between the ba\-9 

 to the bottom ai the burning fuel ; and 

 ihcy sometimes place npon this plate 

 ribs jiri'jectitig upwards, sfi as to fill (he 

 ititersliees or sjtaccs bet«peti the said 

 l)ars or gratings, and present a plain 

 nrfaee to the bottom of the fire ; this 

 sliding or falling plate nay always be 

 removed after fresli coals have been do- 

 Tosited under the fire, as soon as t!ie 

 Leat shall have caused t!ic coals to have 

 a small degree of adi:esion. In stove- 

 jjrates, or kitchea-raiig"s, they some- 

 times make t!ie lowe-t front bar, or tliat 

 froiil bar which is immc'Iiatcly above 

 the horizonirl grating tliat snpjiorts l!ie 

 fuel, to slide np, or to turn ujioti hinges, 

 in order, at pleasure, to give more 

 room than is usual hetveen the grat- 

 ings and tl.e lowest front bar. for tiie 

 reception of their instrument, machine, 

 or apparatus; and thev iesert or deposit 

 fresh coals or'iinburnl fuel under the tire 

 upon th'" lint grating and jilate, by means 

 •t this iuistrumcMt, vviiidi may be culled 



a feeding-sliorel, and consists of a box 

 or scuttle, with a hollow handle at one 

 end, and a (Uior or Hap at the opposite 

 end; this door making an angle of about 

 fortyfive degrees with the bottom, and 

 one hundred and thirty-five degrees vvitti 

 the top of the box; all the other angles 

 being right ones, the box containing » 

 pi.ston, made to slide by means of a pis- 

 ton-rod moving through the handle. 

 l"or large furnace fnes, such as are used 

 in steam-engines, in distilleries, brew- 

 eries, or other works where large grates 

 or stoves arc used, the feeding-shovel 

 may ycry conveniently be made to bold 

 a peck of coals; but lor a small parlour 

 (ire, one holding a ])0und or two of coals 

 will be sntticient. 'I'o bring the feeding- 

 fihovel into action, draw back the piston 

 close to the handle end of the box; open 

 tliC door and fill the box with coals ; 

 shut the door and pass the box with its 

 contents into tlic stove upon the hori- 

 zontal grating above described ; tha 

 door of the box, acting as a wedge, will 

 then lift ti]i the greater part of the fnel 

 previously placed and burning in the 

 stove; then, "by pushing the piston-rod, 

 the piston will press against the coals in 

 the box, and cause the coals to force 

 open the door, and lift up the remainder 

 of the burning fuel; by continuing the 

 pressure against the jiisfon-rod, and 

 withdrawing the box, the whole of its 

 contents will be deposited upon th« 

 grating, aixl nnderncat'.i the burniiij 

 fuel. A fire thus supplied with fuel, 

 scarcely ever requires any other stirring 

 than what it receives from flic action of 

 the shovel at the time fresh coals ar« 

 inserted. 1'he form of their feeding- 

 siiovel may be varied at pleasure; as, 

 .for instance, t!ic piston may slide out- 

 side of f!ie Imndle, or there may be an 

 opening at the end of tlio box ncTii to 

 the handle, for the reception of a de- 

 tiiclied l)i^fon; or tho door or the top 

 piece may be omitted, in which case 

 the coals mi^ht be pushed in under the 

 fire, by means of a detached piston; 

 l)iit, though the patentees mention these 

 as possible variations, they do not re- 

 commend them, because they give th« 

 j)referei:ce to the piston rod sliding; 

 through a liollovv handle, and moving 

 the piston in a box having a door, which, 

 when shut down, shall enter as a wedge 

 under the fire.
