. Specification forming part of Leiters Patent No. 3a',$SS,-dated January 6, 1863.

a cold-air passage arranged concentrically around 1t, and communicating with the het air passage, `as hereinafter described, the same being for thepnrpo'se of avoiding the danger from iire near the floor, and dispensing Iwith the use of the ordinary soapstone for a guard', usual/ly inserted within the door and made to receive the register.

Itlalso consists in .arranging a series of tubes in the hot-air pipe, so that they may he drawn upfor down telescopieally, for the purpose of drawing the hot air from the furnace when it does not corne up readily.

"To enable others skilled in the ari; to ineke andfuse my invention, i will proceed vto de scribe thesanie, reference being had to the drawings accompanying this specification, in which is represented a register applied to the hot-air pipe of a `furnace. with the tubes eonr.

posing the extension-pipes drawn up, as they are required to be in use.

l construct a register by making a circular case, A, rather more than twice as iarge as the outlet-pipe QB, which comes np through the bottom of this case A, and extends upward therefrom about two-thirds of the length of this case. `The top of this Acase is'ler'ei with the Hfloor G, ,and may be secured there in any proper manner, either by being screwed into the door or by a iangerurned over at the top, in which Way I prefer to secure it. Around the top of this case I place a cast-iron collar, D, which is provided `with suitable periorau tions E E E. 0n the inner edge of this'collar is securedthe top of thepipe F, which. is alittle more than half-as long as the case A. By this pipe an annular space is made hetween it and the ease' A. Sliding into the eine r ifi-pleasure@ tubes n and. i; 'rnsmp tube, i, is snrmounted with a register, 3.

The object of the tube F, in combination with the ease A., is to make a space through which the cold air, by means 'of the perforations hl E E, may pass down into the boiy' of the register, and-np 'Withthe het air. The auV rows show the direction of the' current.

The object of the arrangement of the'slding tubes H and I is 'to cause a. draft of het air frotrn the furnace tf1-ascend more' freely in placeswhere from various reasons itdoe's not come up nefast as is necessary to warm the room; illhis register may be setwithent a eoapstone guard with entire safety from fire; and by this arrangement a better circulation of air is made in the apartment, and it is warmed more equally, because the cold air,

which is pressed down near the door of the apartment and readiiy passes down through l the apertures Eto be warmed by the current of I het air from the Yfurnace, and this process being continually repeated the room is warmed quicker than in the usual Way. Y able a damper may he placed in the horizontai part of the hotair pipe B, and the rod con-f nesting 'the damper may he passed up. through the ring of theregister, and the supply of 'not air controlled vin that way; but for general purposes the register in the top of the pipe I will Ahe found amply suicient.- The upright tubes may be made so' as toiit friction tight, orlinay he eid up with a-spring orf Y catch in any suitable anner.

I maire no special claim to the use oi these tubes, out simply to the arrangement of slid ing them up and down, so rhat when not in use they may be ont of sight. Two or more of these tubes may he used, as is desirable.

Haring thus fully described the nature of my invention, what I claim as new, and desire to secure hy LettersjPatent, is-r l l'. The' eombinationsandarrangement, suhsrantially as described, of' the case Aw, the izuheF, and the perforated collar D, with the vfloor C and its register J, and the hot-air in letpipe B, whereby one or more air-passages are so formed between the oor and the hot. air pipe B as' to cause, while het air may be iiowing outof the pipe B, and from thence a 2 :masa
