Application filed December 23, 1895. Serial No. 572,987. (No model.)

To (all whom, it Duty concern.-

Be it known that 1, THOMAS WHEATLEY, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and useful I-Ieater; and I do hereby declare that the following, in connection with the accompanying drawings, is a full, clear, and exact description of the invention.

My invention is a new and improved heater; and it consists of a suitable base provided with novelbearings for the grate-sections and supporting Water-sections of an improved form. These sections are so constructed that the whole body of water is divided up into comparatively small divisions and when assembled form a system of flues and dead ends, so that the heat and products of combustion are brought quickly into contact and are maintained for a prolonged time in contact with large heating-surfaces. These surfaces are for the most part single in thickness and are largely provided with corrugations, which not only increase the heating-surface, so affording a large surface of contact in proportion to the body of water, but act as baflieplates, changing the direction of the draft at every point, thus holding the heat in contact with the surfaces for a longer time. These same results are also promoted by the arrangement of horizontal flues and of vertical flues and dead ends.

My heater is composed of a base having bearings at one side and an elongated slot at the other, through which the grate-sections are easily and separately inserted and in which they are supported. This base forms the ash-pit and sustains the boiler-sections, front, rear, and intermediate interchangeable 40 sections, each provided with downwardlyextending Water-legs longitudinally corrugated, a large central countersunk portion, and upper and lower horizontally-elongated openings through the Water-space. These nected in front by a single vertical flue, and also form between their adjacent faces vertical flues, leading immediately up from the firebox to the lower horizontal flue, and above these vertical flues dead ends, extending far into the upper water-space. By means of the front doors the horizontal flues and corrugations may be easily cleaned, and by means of side doors the vertical flues and dead ends, so that every part of the interior may be reached and cleaned with little trouble.

My invention will be better understood by reference to the accompanying drawings, in which the same reference-numbers refer to the same parts in all the views.

Figure I is a front elevation of my heater. Fig. II is a side elevation of the same. Fig. III is a longitudinal vertical section taken on the central line of the heater. Fig. IV is a vertical cross-section showing one of the intermediate sections in elevation. Fig. V is a top plan view of the heater; Fig. VI, a top plan view of one intermediate section. Fig. VII is a cross-section of an intermediate section taken on line 7 7 of Fig. IV. Fig. VIII is across-section on line 8 S of Fig. IV, viewed from below. Fig. IX is a vertical section on line 9 9 of Fig. IV. Fig. X is a similar section on line 10 10. Figs. XI and XII are enlarged views showing the means by which the sections are attached and connected together. Fig. XIII is a top plan view of the base with the boiler sections removed. Fig. XIV is a front elevation of the same. Fig. XV is a vertical cross-section of the same, showing one section of the grate partly withdrawn.

1 indicates the foundation or base of the heater, forming the ash-pit 2 and having front and rear doors 3 3. In the upper portion of this base is supported in suitable bearings the grate at, and on it is sustained the boiler, composed of front section 5, rear section (3, and intermediate sections 7 7 7.

BoiZer-secti0ns.lhe front section is provided with the usual doors, the clean-out door 8 above, and the sight or feed door 9 below. It has a bottom Water-space 10 in front of the fire-box 11, a lower water-space 12, an upper water-space 13, lower and upper horizontally-elongated openings 14 and 15, and steam-space 16. The intermediate sections 7 7 (best shown in Figs. III, IV, and V to X) products of combustion come in contact are are made similar and interchangeable and longitudinallycorrugated. These corrugated their peculiar construction is an important feature of my invention. They are formed with the central portion of both front an d rear faces countersunk. This countersunk, and consequently thinner, portion of the section extends from the bottom of the lower waterspace 12 nearly to the top of the upper waterspace 13, where it is terminated by the projecting surface 18 of the upper wat-er-space, and toward the sides by the inclined surfaces 19 19, sloping downward from each end of the surface 18. Below and toward the sides it is terminated by the inclined surfaces 20 20,sloping upward and outwardly. These inclined surfaces 1.9 and 20 terminate in the rectangular cut-outs 21 21 in the outer edge of the sections, which form openings normally closed by side doors 22 22, sustained in slides 23 The intermediate sections 7 7 are also provided with lower and upper horizontallyelongated openings 14 and 15, corresponding with the same openings in the front section of the boiler and also with corresponding water-spaces, the lower 12, the upper 13, and steam-space 1G. The rear face of the front section has its central portion countersunk, corresponding with the formation of the intermediate sections. By this construction when the sections of the boiler are assembled the openings through all the sections correspond and form the lower horizontal flue 1i 14,extending continuously from front to rear, and also the upper horizontal flue 15 15, connected to said lower flue by a front vertical flue 24, formed in the front section 5 between the clean-out door 8 and the upper waterspace 13. By the countersunk formation of the faces of the sections when the sections are assembled vertical flues 25 25 are formed between their adjacent faces,leading,through the lower water-space 12 12, from the fire-box 11 to the lower horizontal flue 11 1t, and immediately above these fiues 25 25 the dead ends 26 26, extending into the upper waterspace 13 13 and terminating near its upper surface. The rear section 6 of the boiler is provided with a lower water-space 27, an upper water-space 28, a lower smoke-flue 2!), leading directly to the stack 30 from the tirebox, and an upper smoke-flue 31, into which pass the products of combustion from the upper horizontal flue l5 15. This rear section is preferably countersunk on its forward face to correspond with the countersunk portion of the adjacent intermediate section, as seen in Fig. III. 011 the back of this section is attached by any suitable means a smoke-bonnet 32, by which the products of combustion, having passed through the horizontal fines in the boiler, are received from flue 31 and thrown downward before they pass out into the stack 30. Upper and lower dampers 33 and 34: are also provided.

Corrugated surfaces-The greater portion of the surfaces with which the heat and the surfaces are the top 35 of the iire-box,the sides 36 36 thereof, (being the inner surfaces of the water-legs 41 4.1,) and both the lower and upper faces of the horizontal Hues 14- 14 and 15 15, said faces (or walls of the water-spaces) being indicated, respectively, by the numbers 37, 38, 39, and 40. 15y this peculiar construction of boiler or water sections the heat comes immediately in contact with large heatingsurfaces, being for the most part of a single thickness of metal. The heat remains for a long time in contact with said surfaces, the corrugations and the dead ends increasing the heating-surface and acting as bafiie-plates to turn the draft at every point.

Means for cormect ing the sections-I have provided a simple and eifeetive means for firmly connecting together the sections of my boiler and simultaneously making connection between the adjacent water-spaces to take the place of the cumbersome and expensive external connecting-drum in common use. This connection is best shown in Figs. II, V, XI, and XII. On both faces of each intermediate section two of the corners namely, one upper corner 42 and the diagonally opposite lower corner 43-are out out, leaving small rectangularrecesses, in which are tapped screw-threaded holes 44 through the metal into the water-space. Short pieces of pipe or nipples 45 are provided, with their ends right and left threaded to engage with these threaded holes. \Vhen the sections are set together, the cut-out corners or recesses 42 and 43 on adjacent sections correspond. The nipples 45 are set to engage with the holes on each side and screwed tight, whereby the adjacent sections are drawn strongly together and communication is offected between the adjacent water-spaces. Lock-nuts -16 46 are also arranged,engaging with the threads on the nipples for making a tight connection, and where desired rubber washers at? 47 may be interposed between the lock-11uts and the adjacent surface. The rear face of the front section and the front face of the rear section have diagonally opposite corners similarly recessed to permit the use of the nipples and the attachmentof these sections by this means to the adjacent intermediate sections. iy this means it will be seen that the water-legs of the adjacent sections are connected together alternatelyon one side and the other, and the adjacent steamspaces also alternately on one side and the other, the arrangement of these connections being best shown in Figs. II and V, so that the connections between the steam-spaces are arranged in alternation with the connections between the water-legs 4:141 and are never arranged directly over them.

lllcmner of sustaining grate-sections. -This is best shown in Figs. XIII to XV. Base 1 is provided with bearings-50 to receive the inner ends 51 of grate-bars. On the other side the base is provided with the elongated slot 53, through which the grate-sections 52 are easily slipped into place and in which rest the outer ends 54 of the grate-bars. A lock ba1 55 is pivotally connected at one end 56 to base and is provided with notches 57 57, fitted to the grate-bars 54C, and with a latch at its opposite end. When this lock-bar is dropped into position, its notches 57 57 engage with the grate-bars 5a 54, preventing the withdrawal of the grate-sections 52. The grate-sections may be connected together by any desirable means, as by the connectingbar 58, pivoted at 59 59 to the links 60 60, which engage with the angular ends 61 61 of the grate-bars 54 54. To one end, preferably the forward, of this connecting-bar 58 at 62 is pivotally connected the lever 63, journaled to the base at 64, by which means all sections of the grate may be rocked simultaneously. If desired, any single link 60 may be taken off and the particular grate-section 52 left motionless while the rest are rocked, or the connecting-bar 58 and all the links 60 60 may be omitted and each grate-section shaken separately by means of a handle fitting its square end 61.

Gages and connections-My heater is provided with the ordinary fittings of steam-gage 66, connected by pipe 67 to steam-space 16, water-gage 68, connected bypipes 69 69 69 to the water-spaces and blow-off cocks 70 70. 71 71 are connections for the outflow-pipes, 72 for the safety-valve, and 73 for the waters pp y- Adncmiages.-By my improved construction of heater I obtain the following advantages: quick contact of heat and products of combustion with maximum of heating-surface; good circulation and maximum of time of contact; corrugations and dead ends increase heating-surfaces and, acting as baffleplates, prolong time of contact; increase in single-thickness heating-surfaces; therefore sections lighter and saving in metal and expense; simple, cheap, effective means of connecting boiler-sections; simple means for sustaining grate; finally, cleaning made easy, every inch of interior reached directly through front or side doors; corrugated surfaces easily cleaned through front doors, soot fallingdown; vertical flues and dead ends cleaned through side doors.

It will be evident that this construction of heater can be used either for steam or hotwater heating. If for the latter, there will be no steam-space, properly so called.
