Application filed April 18, 1921. Serial No. 462,391.
To (ZZZ whom it may concern.
Be it known that I, EDGAR C llloLBY, a citizen of the United States, residing in the borough of Brooklyn, city and State of New York, have invented new and useful Improvements in Heaters, of which the following is a specification, reference being had to the accompanying drawings, in which- Fig. l is a section of a heater embodying my improvements; Fig. 2 is a section on lines II-I of Fig. 1; Fig. 3 is a perspective of my improved heater; Fig. 4c is a side elevation of a modified form of my invention; Fig. 5 is a plan thereof; Fig. 6 shows the heater in elevation in position in a wall and arranged to act as a hot air heater; and Fig. 7 is a front elevation thereof.
My invention relates to heaters, and comprises a heater adapted for room use which combines the advantages of a room heater with an open grate fire in a compact and sightly body. I prefer to employ a heater of the down-draft magazine-fired hot rater type which has been particularly improved and adapted for this purpose. My invention also comprises the construction and arrangement of parts which I shall hereinafter describe and claim.
Referring to the drawings, the heater is comprised of a plurality of water sections 2 connected at top and bottom by the nipples 3, and between the water sections are arranged the fines 4, which lead out of the co1nbustion chamber 5 in front of the water sections. Above the combustion chamber and also in front of the water sections 2 is a fuel reservoir or magazine 6 which supplies fuel to the combustion chamber 5 and into which fuel is introduced through the door 8. The breast 9 of the heater may be water cooled as shown.
The fuel is supported in the bottom of the combustion chamber by the revolving grates 10, and at the front of the heater by the inclined grate 11, which may be adjusted to vary the widthof the combustion chamber, depending on the character of the fuel used. Access to the ash pit 12 is had through the door 13, and to the fire through the grate 11 by the door 14, which is supported by its trunnions 15 which seat in the elongated sockets 16 at the sides of the door frame. In closed position the door 14 is supported along its lower edge on the shoulder 17 of the ash pit door and along its upper edge by a downwardly turned lip 18 which fits into a groove 19 at the top of the door frame. in opening the door 1 1, it is slightly lifted and its upper end pulled forward to disengage it from the shoulder 17 and groove 19, and is then lowered, rotating about its. trunnions 15 until its lower end comes in contact with the stops 20 in front of the lower end of the grate 11. In this position practically the whole front of the grate 11 is exposed, thus giving the effect of a grate fire and also enabling the fire to be sliced through the grate 11. When the door 14. is in lowermost position it acts as a hearth for the grate and prevents ashes from falling out on the floor.
In operating my improved heater, after a fire has been kindled on the grate bars 10, fuel is fed in through the door 8. Air for combustion passes from the door 14, either by opening it as indicated in the dotted line position of Fig. 1, or by opening the small slides ll therein, through the grate 11, between the grates 10 and 11, and through the grate 10, as is indicated by the arrows in Fig. 1. As the coal burns away in the combustion zone the unburned coal in the magazine above drops down and thereby supplies fresh coal for combustion.
As the burning gases pass out into the fines 4, which are formed by concave depressions in the sides of each water section, they are deflected by the blades 21, which give the gases a more tortuous course, and then pass upwards over the diaphragm 22 and then down to the horizontal flue 23, which leads to the connection 241 with a chimney. The heated water passes out of the heater through the outlet boss 2 1 at the top of the heater and suitable piping 25 to a radiator or radiators 26 in the same or in adjacent rooms, from which it is returned. to the heater through the piping 27 and the inlet boss 28.
Where it is desired to utilize the waste heat for heating water for domestic purposes, a hot water coil 29 may be arranged around the connection at.
In Figs. 4 and 5 I have shown a modification of my invention in which a kitchen range 31 is attached to the rear end of my improved heater. In this form the products of combustion are led from the fines a into the parallel flues 82, which are arranged immediately beneath the top of the range 31 and pass around the diaph agms into the common flue 35, and from thence to the chimney connection 36. if desired, this form of my invention may be arranged in a wall or partition 37, so as to have the grate fire in one room and the range top in another room, as. is shown in Fig. l.
In Figs. 6 and 7 I have shown a further modification of my invention, in which the heater is arranged to act as a hot air heater in addition to its other functions. The heater is shown arranged in a wall 41 with a hood 42 spaced away from, and forming a compartment 43 with, that portion of its rear and sides which projects through the partition. Cold air may be supplied through either an air shaft 44 or by drawing it through the damper 45 from the same room into which the heater projects. The air in the heating compartment 43 as it becomes heated will rise and may be utilized. by passing through a register at) into the room, or may be diverted to another room through the register 47.
My invention is of especial advantage in providing in a compact unit a heater, preferably of the hot water type, for room use, and which permits the directheat of the fire to be utilized in the form of an open grate. My improved heater by reason of its design is particularly efficient and economical in operation.
The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural n'iodilications are possible within the scope of the inventioi'i claimed.
What I claim is:
1. A heater comprising in combination a casing enclosing a fixed fuel magazine, and a combustion chamber beneath said magazine, there being an opening in the front of said casing approximately coextensive in height and width with the combustion chamber; an approximately vertical grate mounted behind said opening; an offtake for products of combustion leading from said combustion chamber at a point opposite said grate; a second grate serving to support fuel in said combustion chamher; and a draft-controlling door mounted on said casing and movable between two positions, in one of which it serves as a hearth, and in the other of which it closes said opening.
51A heater comprising in combination a casing enclosing a fixed fuel magazine, and a combustion chamber beneath said magazine, there being an opening in the front of said casing approximately co-extensive in height and width with the com bastion chamber; an approximately vertical grate mounted behind said opening;' means for adjusting said grate inward and outward at its lower edge to Vary the effective cross section of said combustion chamber; an offtake for products of combustion lead-- ing from said combustion chamber at a point opposite said grate; a second grate serving to support fuel in said combustion chamber; and a draft-controlling door mounted on said casing and movable between two positions, in one of which it serves as a hearth, and in the other of which it closes said opening.
3. The combination with a magazine-fed, sectional hot water heater having a combustion chamber, a front opening approximately co-extensive with said combustion chamber, and an offtake leading from said combustion chamber at a point diametrically opposite said front opening; of an approximately vertical grate defining the front of said combustion chamber adjacentsaid opening; and a draft-controlling door serving alternately in its closed and open positions to close said opening and to expose said grate and the fire supported thereby to view.
