`aenorrrrirtiris! strain-#Huertas Specification forining part of Letters Patent No. 128,721, dated July 9, i872.

To all whom imag concern.'

.BeitA hnoivnthat I, JOHN L. Fnrsnin, of the city, county, and State of New York, have invented a new and Improved Steam-Heater; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked,` thereon making a' part of this specification.

'.ihe object of this invention is in thenature of an improvement in steamheatere; and the invention consistsin constructing the base of said heater in such manner as will allow oi a constant circulation of steam through the pipes, and at the same time prevent the condensed steam from interfering with the passage of steam through the pipes, or in anyway interfers with their operation. 'The invention also consists in joining the upper ends of the tubes in such manner as will retard lsomewhat the passage of` steam throughpipes, and also in covering 'the upper parteci said heater or pipes' with a perforated plate, which, to some extent contines the air surrounding the vtop of said heater, until it becomes thoroughly heated; and' the invention still further'consists in .inclosinggl the heater in such manner as will enable the outside air to entirely surround the heater, Where it is to some extent `kept until thoroughly heated, finally finding exit through a perforated plate into the ilue or iiues.

, In the aoom'panying' drawing, Figure 1 repl resents a sideelevaton of my heater with the inclosure in section; and Fig. 2 is a plan or top view of the same, partly in section, and with the perforated covering removed.

Similar letters of reference indicate like parts in the several figures.

'b .represents metallic pipes which may be of any desired size and number. The lovver ends of thesefpipes are secured to and open into a base, a. This base has an opening, l, extend ing nearly its entire length. (See Fig. 2.) Arranged on either side of this opening l, and.

across the rear part of the base a in parallel rows, are the pipes b. The base a is hollow, and has cast or otherwise secured therein a partition, s, which extends `between the parallel openings of the pipes b, and dindes sani base into two lparallel Achannels j undp, one

end of said partit-ion s, dividing the opening 'd' in said base vinto t Wo parts, and the other end of said partition diverges so as to bring the vopening of the other orifice d entirely within one channel, p, only. The 'upper ends of said tubes vhave itted to them square hollow boxes o, which, being fitted and joined together, make compact and ,secure the upper ends of said pipes, and thus form the -top surface ot the heater. nihis top surface is now cov-V ered With'a perforated plate, h. The heater thus constructed is placed withinanysuitable y incloeure, A, of brick or iron, the inclosure havnig; at its front end a door, y, and at its rear end, near the-top, a tine-opening, i. Viithinl the iuclosure, between the end of said heater and said flue-opening, is amxed a perforated plate, h.

The heater being thus .constructed and incisedhitsoperation'is as llo'ws'i Seain lieiup,r admitted through the opening d it passes around the channel p and up into the tubes b through the openings m, and through the boxes c, wherein by reason of their angular shape it is retarded slightly in its passage down the next adjoining set of tubes intovthe ehannelj, and in this *way a constant circulation of live steain is kept up Within the tubes, the condensed steam remaining by its gravity at-the bottom oi' the base a, oii'ering no obstruction to the passage ci' the steam through or into pipes t, which passes over the Water thus remaining, and blowingo any great anonimiy i lation vof Water through the oriiice d', which is, common to both the channels j andp. The door of the inclosure being opened, the out. y'

side air is admitted within said inclosnre, sux'-,

rounding the heater, the opening ifacilitznbingh a free circulation of airbetvveen the pipes un? til it arrives at the top ofthe heater, where it y meets with the heated surface of the perforated plate h. This plate offers more or-less-obstruction to the free escape of the surroundf ing air from the heater, thus insuring its bev coming thoroughly heated before it escapes.

The air within the inclosure A is still further retarded, and for the same purpose, as it rises from the heater, and before it passes to 4the flue, by the perforated plate h,`when it,-

iinally escapes through the nue-opening to be conducted throughout the building.

it is obvious that a steam-heater construct'- ed and operated as above described allows the constant circulation of live steam through its pipes, in this way increasing the heating capacity of its full surface, and avoiding loss and annoyance by condensed steam in the pipes, besides heating the 'air to a greater extent, it is believed, than is done by any other steamheater or radiator, making my heater economical and eiective in its operation.

Having thus described my invention,whatI claim as new, and desire to secure by Letters Patent, is-

1. The base of a steam-heater or radiator, divided by vertical partitions into two parallel channels, as and for the purposeherein de scribed. v

2. The combination of the pipes of a steamheater with rectangular' box headings and a base, divided substantially as herein described.

3. The combination of a steam-heater, having the base thereof divided vertically into parallel channels with a perforated top plate, as shown and described.

. 4. The base of asteam-heater, having a rectilinea'r opening, l, therein, as shown and described.

5. The combination of a steam-heater, as

above described, with an inclosure having a perforated plate interposed between said heater and the flue-opening in said inclosure.
