WATER-HEATING ATTACHMENT FOR RANGES.

SPECIFICATION forming part of Letters Patent No. 440,970, dated November 18, 1890.

Application filed July '7, 1890. Serial No. 357,976. (No model.)

To all whom it may concern/.-

Be it known that I, HENRY C. STEINHOFF, of the town of Union, in the county of Hudson and State of New Jersey, have invented a new and Improved \Vater-Heatin g Attachment to Ranges, of which the following is a full, clear,

and exact description.

' water-heating attachment My invention relates to ranges or stoves and more particularly to ordinary cooking or kitchen ranges, and has for its object to provide such ranges with a simple, inexpensive, and efiicient system of water-pipes applied independently of the ordinary waterback, and adapted to heat water and maintain circulation of it through radiators for thereby heating other rooms than that in which the range is set.

The invention requires little or no change in the construction and no change in the setting of the ordinary range, and in its preferred embodiment is adapted by the simple manipulation of a damper to be made operative or inoperative at pleasure.

The invention will first be described, and then will be particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front vertical sectional elevation of an ordinary kitchen-range fitted with my improvement and taken on the irregular line 10 w in Fig. 2. Fig. 2 is a plan view of the range and attachment in horizontal section on the line so so in Fig. 1. Fig. 3 is a vertical transverse sectional view taken on the line y y in Fig. 1, and as arranged for using the Fig. L is a detail View showing the guard-plates adjusted, as when the water-heating attachment is not in use. Fig. 5 is a detail front vertical sectional view taken on the line 2 in Fig. 4, and Fig. 6 is a face view of one of the heat-deflecting plates used in the water-pipe flue.

a a lead cold water to and discharge hot water from the water-back to the ordinary hot-water boiler. (Not necessary to show or describe, as this boiler and water-back form no part of my improvement.)

In carrying out my invention I utilize the space usually left below the top plate and behind the back plate of the range in which to locate the greater portion of the auxiliary water-pipes B, which makes the heat of the fire-pot available for heating said pipes. In the preferred construction shown in the drawings the water-pipes B are arranged with a return-bend b, which is located at the upper part of the fire-pot and forms a portion of the side wall of the pot opposite the Waterback a, which forms the opposite side wall of the pot. The lower part of this bend b is extended outward and forms the cold-water inlet 1) to the whole system of pipes B, and will be connected with any suitable source of water-supply. The upper part of the pipebend I) is fitted into a hollow coupling-box 6 made large enough to receive the ends of any desired number of pipes 11 forming the rear horizontal portion of the water-pipe system B. I show four of these pipes 17 but any desired number may be used.

A partition 0, having a rearward right-angular extension 0, is fitted between the top of the oven and the range-top plate and separates the space or hot-product chamber, opening to and from the firepot a into two independent fiues c 0 the former overlying the range-oven and the latterforming a rear flue traversed by the system of pipes B. The hot products from the fire-pot thus may be directed either through the flue 0 containing the water-pipes B, or directly over or around the range-oven to the hot-product outlet or exit-flue of the range. hot-product outlet in the form of a bonnet D, which has a central vertical partition (1 above the part c of the range-partition O, and thus divides the bonnet into two chambers d 61 both of which have communication with a common exit-pipe (1 which is fitted to the top of the bonnet and conducts the hot products to a chimneyiiue. A damper E, fitted, preferably, to the top of the bonnet-partition d, where it is pivoted, may be swung down, as shown in full lines in Fig. 1, to close the bon- I prefer to make the net-chamber d to the exit-flue (Z and may be swung over, as indicated by the dotted lines, to close the bonnet-chamber d to said fine. By using this double-chambered bonnet D, I am enabled to continue the series of pipes B beyond the horizontal pipes 12 by a connected series'of vertical pipes b, which range upward through the bonnet-chamber (1 with which the hot-product flue c communicates. I prefer to connect the upper ends of these pipes b with the hollow box-coupling 12 from which extends a pipe I), which conveys the hot water from the entire pipe system B to any number of radiators (not shown) and placed in other apartments to heat them by the same fire in the range which does the cooking for a family. I prefer to fit into the hot-product flue c and the bonnet-chamber (1 a series of deflecting-plates F, slotted to admit the pipes B, and fixed to the opposite walls of the flue and chamber to retard the passage of the hot products and deflect them in a sinuous course toward the exit-flue to assure their best effect in heating the waterpipes.

As it is necessary to use the auxiliary water-pipe system B only in cold weather for heating adjacent rooms, as above described, it is desirable to protect these pipes from the heat of the range fire-pot at other times. I accomplish this by employing a guard, which may consist of one or more refractory plates. I show two guard-plates G H, the former being angular in cross-section and set upon the permanent fire-brick lining of that side of the fire-pot a, and extending over the pipe return-bend b to shield it from the heat, while the other fire-brick plate H, in conjunction with a suitable lug g, formed on the guardpl'ate. G, closesthe end of the water-pipe flue 0 to cut off therefrom the hot products from the fire-pot. The guard plate or shield G, and without the lug g, may alone be used, because when the damper E is set to close the bonnet-chamber d to the exit-flue cl the draft from the fire -pot will be induced directly through the ran ge-flues c to the exit-ii no, and the pipes 12 in the flue 0 will not be dangerously overheated. It may be preferable, however, to use both guard-plates G H, as above described.

The operation of my invention is very simple and effective. \Vhen the guards G H. are removed from. the pipes B and their flue c and the damperE is adjusted as shown in full lines in Fig. 1 of the drawings, the hot products fromthe fire pot Ct of the range will pass through the flue c and bonnet-chamber d traversed by the pipes 13, to heat the water in the pipes and supply the connected radiators in adjacent rooms for warming them; but when the damper E is adjusted as indicated in dotted lines the hot products from the range fire-pot will pass directly through the flue c and bonnet-chamber d to the exitflue and chimney, the guards G H being then adjusted to shield the water-pipes B from the heat.

I show the l1ot-product fine 0 with independent bottom and rear walls, connecting, respectively, with the bottom and top plates of the range; but the bottom and rear walls of said flue a may be formed by the brickwork into which the range may be set, as will readily be understood.

I am aware that bodily-removable circular or rectangular fire-pots hax c been fitted within the main fixed fire-pot of ,a stove or range, and that ordinary slide-dampers have also been used as guards against needless or excessive heating of water chambers or pipes at or next the main fire-pot when heating of water for warming adjacent rooms is not required, as in warm weather, but I am not aware of any prior construction in which a water pipe or coil has been arranged along the. side of the main fire-pot and adjacent to and back of a shoulder or ledge of themain fire-pot, formed, preferably, by a brick or refractory lining thereof, whereby a simple bodily-removable shield-plate, preferably made of fire-brick, may be sustained on the fire-pot ledge to guard against excessive or unnecessary heating of the pipe or coil; neither am I aware of a prior construction in which a bodilyremovable guard or guards have been used in connection with a pipe or pipe-coil at the side of the main fire-pot and extended into an adjacent hot-product flue, said guards serving both to shield the pipe or coil at the side of the fire- IOC pot and to cut off entrance of hot products to the flue traversed by the water-heating pipes, and whereby the entire system of auxiliary water-heatin g pipes may at pleasure be shielded from excessive heat from the fire -pot. Manifestly a bodily-removable imperforate guard, when taken away from pipes ora pipecoil at the side of the main fire-pot, allows far more efficient and economical heating of said pipe or coil than would a perforated dam-per base-plate when the. damper is open, as a damper and its base-plate which are not bod ily removable from between the auxiliary water-heating pipes or coil and the fire-pot would,when the damper is open,prevent full heating effect of the fire-p0t on the pipes, which is assured by my construction allowing entire removal of the guards and consequent full exposure of the heating-pipes to the hot products of the fire-pot.

Having thus described my invention, what I claim. as new, and desire to secure by Letters Patent, is
