To all ZU/(UHL it may concern: off the steam lie it known that l, ALONZO J.

'ihe objectot' my inventhm is to prcrentthe A steam-pipe, I), with elbows 1) flow of cold air into the furnace through the of its ends, is arranged horizontally above the door by a simple means which may be applied furimcc-door, so that the body D of the pipe to any furnace oi ordim'iry constructitm, and I will extend entirely across the dooropening, I and the lower portion of the pipe is perforated l l l and provent'its unneeeiisary titsinto and covers the D at each will in noway interfere with access to the burning coals upon the grate, to feed the furnace, to direct the steam vertically in a sheet across to properlydistribute the fuel over the tire-bed, the inneriace ofthe furnacowalls,immediately or for other purposes; and the improvement in front of the furnace-door. The elbow D consists, first, in the combination, with a furof the stcanrpipe is closed by a plug, and simnace, of a pipe arranged above or around the plyserves to support oncendot'thepipe bypassdooi rmeningthat communicates with the ing through ahollowstay-bolt,B,.eonnecting stcanrspacc of the boiler, and is provided with the double plates of the furnace. The other a valve to regulate the admission of steam to end of the pipe I.) is similarly supported by an elbow, D", passing through ahollow stay-bolt, I3 and is provided with a valve, E, arranged the portion of the pipe within the furnace, the
said inner portion of the pipe being perforated to cross its opening and be operated upon through a cran t-sha-ped valve-stem, c, to admit in such manner as to direct the steam escapsteam to the pipe .l) from the pipe D, that ing through the perlorations across the doorconnects the hollow elbow D with the steamspace of the boiler.
A. plate, l provided with an its upper end and notched at its lower end, is arranged to slide vertically against the outer wall of the furnace, and is held in place by a pin, f, secured to thcfurnaee-walls, that passes through a longitudinal slot, f in the plate. The plate I I the cran k c, passing through the eyeboltf, and is connected with the doonlatoh by passing through the note-hf in its lower end.

air of the furnace from the outer air, and warm the air that may pass through it to such a de gree that-its admission to the burning coal within the furnace will not chill the flame and prevent its effectual combustion.
Myinyention further consists in connecting the Valve of the steam-pipe, combined with a furnace, as above described, with the latch of the furnace-door, in such manner that when the latch is raised to open the door the valve will be opened to admit steam through the perforations of the pipe, and when the latch is closed the valve will also be closed to shut eyebolt, f, at
)3 is connected with the valve E bv It will thus be seen that when the latch is raised to open the furnace-door the bar valvestem e and valve E will be lit-ted to admit steam into the pipe 1), and allow it to pass through the perforations of the pipe and be driven across the furnace-door opening in a sheet, and in such quantities that the door-opening will be screened to exclude the outer air from enteriug the furnace through the dooropening' in large volumes, and will heat the air that does enter to such temperatul'e that the combustion of the fuel in the furnace will not be checked by the cooling effect of air at a low temperaing the fires and allowing;
ture. By this means the furnace-door can he left open a reasonable time to allow the coal to be properlydistributed upon the grate-bars, and for removing clinkers or other non-combustible n'iate'rial from the furnace without killdrat'ts of cold air to sweep across the furnace and through the tlues and inner passages of the boiler, which would quickly reduce the temperature of the water and steam within the boiler, and cause not only a loss oi fuel, but a decreased steam pressare and vohnne,\\'ith a consequentlossol' speed of tlur-l-ngino.
[n locomotiyeengincs the reduction of speed caused by opening, the furnace-door is a serious detriment, and by the above-described means may be avoided almost totally.

[n afurnace for steam-boilers and similar purposes, the combination of a perforated steam-pipe arranged within the furnace near the door-openin a" and connected with the steamspace of the boiler, and a valve to regulate the admission of'steam to the perforated portionrof the steam-pipe, the steam-pipe being arranged to direct a sheet of steam across the furnacedoor opening, substantially as and for the par-7 pose described. I
.5. The combination, with the furnace of a steam-boiler, ot' a perforated steam-pipe arsuch manner as to direct the steam across the inner face of the door-opening, and a valve for regulating the admission of steam to the perforated pipe that is connected with the door in such manner that when the door is opened or closed the valve will be correspondingly operated through the connecting mechanism, substantially as describcd.
3. Thecombination, perforated steam-pipe l), valve l), vertical rod, and door-latch, pivotally secured midway of its length to the door, and projecting beyond it in such manner that one end of the latch may all'ord convenient means for actuating the rod 1* at its otherend, substantially as and for the purpose described.
