REG EN ERATIVE BURNER.

SPECIFICATION forming part of Letters Patent No. 404,063, dated May 28, 1889. Application filed September 14, 1888. Serial No. 285,382. (No model.) Patented in Belgium April 24, 1888, No. 81,537.

To all whom it may concern:

Be it known that we, ROUGHSEDGE WALL- WORK and ARTHUR O. \VELLS, subjects of the Queen of England, residing at Manchester, in

the county of Lancaster, England, have inour improved regenerative burner supplied with combustible liquid from a stationary or portable reservoir, and Fig. 1 is a detail view. Fig. 2 is a sectional elevation of the burner and its connection with the supply-pipe. Fig. 3 is a top plan view of the burner, the shield being removed and shown in dotted lines. Fig. l is an end View of the burner, the shield being also shown in dotted lines. Fig. 5 is a top plan View of the burner-shields, and Fig.

0 an end elevation thereof. Fig. 7 is a top plan View of a portion of the burner-shield and its directing-vane. Fig. 8 is a top plan View of a double burner embodying our invention, and Fig. 9 an end elevation thereof. Figs. 10, 11, and 12 are detail sectional views of the injector-nozzle. Fig. 13 is an end elevation of Fig. 12.

This invention relates to that class of burners known as regenerative, burners, and more especially designed for use with combustible liquids, the liquid being converted into a gas prior to its reaching the zone of combustion.

Our improved burner is intended more particularly to be used in the open atmosphere, where it is subjected to the action of currents of air liable to vary in direction. The burner is also intended for the use of the cheaper impure hydrocarbons or products of hydrocarbons usually combined With more or less tar and other impurities, though it may be employed for burning pure or refined hydrocarbons, or products of hydrocarbons or other more or less volatile combustible liquids.

These burners are admirably adapted for use on board ships above decks, Where they are continuously under the influence of strong drafts or currents of air, and they may be provided with adirecting-vane to hold the burner at all times on a line with the air-currents.

The invention consists in the combination, with the supply-pipe, of a horizontally-revoluble regenerative burner, substantially as hereinafter described and claimed.

The invention further consists in the combination, with a horizontally revoluble regenerative burner, of a directing Vane for holding the burner in the direction of an aircurrent and causing it to shift its position Whenever such current shifts from one direction to another, substantially as hereinafter described and claimed.

The invention further consists in the combination, with the burner and the regenerative tubes or pipes, of a shield to protect the burner against rain or snow, and under some conditions of use to prevent the radiation or dissemination of the heat from the flame and direct said heat to the regenerative tubes or pipes, substantially as hereinafter described and claimed.

The invention further consists in structural features and combinations of parts, substantially as hereinafter described and claimed.

A convenient mode of and means for supplying the burner with combustible liquid is shown in Fig. 1, Which we do not desire to claim in this application, as such mode and means will be claimed in separate applications for patent, and need, therefore, not be described in detail here, except in so far as may be necessary to the description of the burner. It will be understood, however, thatany other means or devices may be used for supplying the illuminant under pressure to the burner.

Referring to Fig. 1, A is the reservoir for the combustible liquid, provided near its bot tom with an exhaust stop-cock, a, and near its top with a pressure-indicator, a Extending into the reservoir is a pump-barrel, A, the head of which, outside of the reservoir, is provided with a branch, a, for a hose, so that a combustible liquid and an elastic gassuch as airmay be forced into the reservoirand compressed therein, or so that the air in the empty reservoir may be compressed by the combustible liquid forced into said reservoir for forcing said liquid to the burner.

B is the service or supply pipe, provided with regulating devices for regulating the flow of the combustible liquid, which may be of any desired construction, but preferably of the construction and arrangement shown in Fig. 1, as great advantages are derived therefrom. These devices consist of a coupling, 1, provided with lateral branches 2 and 3, diametrically opposite each other, said coupling having an axial partition, 4, extending across the axial plane of said branches 2 and 3. In the partition 4 is formed a port, 5, provided with a cone-seat for the cone end of the regulating-screw 6, that works in an interiorlythreaded stuffingbox, 7. In the branch 3 is screwed a hollow screw-plug, 8, Fig. 1, that is open at one end, which end abuts against the partition 4 around the port therein, said hollow screw-plug being provided with peripheral ports 9 and an end flange, 10, the perforated tubular portion being covered with a filtering medium, 11, such as wiregauze. By means of this arrangement all impurities or solid matter are prevented from passing to the burner, and by unscrewing the plug 8 the filtering medium, as well as the interior of the plug, may bereadily cleaned, while ready access is aiforded to the interior of the top casing. v

The supply-pipe B projects into the reservoir A to near the bottom thereof, and at its outer end is provided with coupling devices for coupling the burner thereto. These devices (shown in section in Fig. 2) consist of a stuffing-box, b, screw-threaded interiorly and provided with an axial aperture for the passage of the burner-pipe E, which also passes through an exteriorly-screw-threaded packing-gland, 1), provided with a handle, b for screwing-it into the stuffing-box to compress the packing therein, the pipe E having a collar, e, seated on the stuffing-box gland to form joint at that point and prevent the pipe from entering farther into the supply-pipe B, as shown in Fig. 2. The pipe E isbmt and has the burner screwed thereto, so as to hold the latter in a nearly-horizontal plane.

This burner consistsof an injector-casing, 0, provided with a. lateral arm on which is formed a coupling, 0, for the pipe E, and the heater or regenerative extension E of this pipe, that projects some distance beyond the injector O, and is connected with a tubular cross-coupling, 0 to which is also connected the return regenerative pipe E whose inner end is connected with a branch, 0 of the casing 0 and in communication with the chamber thereof.

As will be seen by an inspection of Fig. 3, the regenerative pipes E E are arranged parallel to each other on opposite sides of and immediately above the nozzle of the injector C, so that the flame issuing from the nozzle or from a combining-cone in front of it, hereinafter referred to, will impinge upon the pipes the'full length thereof, or nearly'so, the combustible liquid having such a distance to travel over intensely-heated surfaces before it can reach the inj ector-nozzle. as not only to completely volatilize the liquid, but to superheat the vapor or gas, so that the latter will reach the burner in the very best condition for consumption or combustion, and so that when mixed with a suitable volume of atmospheric air the maximum illuminating or heating power is obtained from a given illuminant. The pipes as arranged form substantially a multitubular converter or regeneratorheated. by the burner-flame.

The cross-cou linrc hasthree screwlu s p b b 7 21, 22, and 23, to-aft'ord access tothe bore of said coupling and to the interior of the pipes E and E respectively, the injector-casing 0 being likewise provided with three screwplugs, 24, 25, and 26 one in the plane of the injector, the other in that of the pipe E and the third in the transverse axial plane of the casing,,respectively, and for like purposes.

The injector 0 consists of a tube provided 'with a nozzle-head, c, that has a small axial gas orifice or passage, 0 as shown in Figs.

10 and 11, or with a plurality of such passages grouped around the axis of the nozzle, as shown in Figs. 12 and 13, said tube being screw-threaded for a portion of its length immediately in rear of the nozzle-head for securing it to the injector-casing C. The tube is open at its inner end, and when screwed to the burner said endlodges in a recess, 4

formed in the outer end of the screw-plug 24,

as shown in Fig. 2, and is closed thereby.

The injector-tube C may have numerous small peripheral perforations or ports, 0 for the passage of the gas or vapor, as shown in Fig. 10, or it may have a few large ports, as shown in Fig. 11, in which case weprefer to introduce into the tube a wire-gauze cylinder, 0 toprevent any solid matter from entering the nozzle and obstructing the small outlet orifice or orifices.

"When the injector has aplurality'of outletorifices, the aggregate area thereof will be equal to the area of the single outlet-orifice, as will be readily understood, and this area will vary within certain limits, according to the nature of the illuminant used, and also according to the area of the regenerative to or formed on the lateral coupling-arm c of the casing O and depends therefrom immediately in front of the injector C and concentric therewith. The jet or jets of gas or Vapor ejected produce a partial vacuum in the combining-cone D, entrainin g the ambient air into the cone, wherein it mixes more int-imately with the vapor than would bethe case were no combining cone employed. The flame resulting from the combustion of the hydrocarbon gas or vapor in front of the combining-cone D impinges upon the pipes E E as stated above, to convert the combustible liquid into a gas and superheat the gas before it reaches the burner for the purposes stated. The illuminating or heating power of the burner may be increased considerably by duplicating the parts thereof, as shown in Figs. 8 and 9, there being two injectors, O 0, two combining-cones, D, and a return heating or regenerative pipe, E, for the second injector, both injectors being supplied by pipe E. The illuminant from reservoir A passes through pipes E E to the cross-coupling 0 where it divides into two streams and passes to the pipes E E and thence in the form of vapor or gas to the respective injectors, an additional screw-plug, 27, being provided in said cross-coupling c for pipe E as shown, and for the purposes stated.

The burner,'as described, is applicable for general indoor use. We have, however, stated hereinbefore that the said burner is more especially designed for use in the open air and on board ships, where it is or may be subjected to the action of strong and shifting air-currents and to more or less vibration.

To protect the burner against the inclemency of the weather, and also to prevent the loss of heat from the flame, and to prevent air-currents from deflecting the flame from the regenerative tubes or pipes, we provide a shield, F, of thin sheet metal, as shown in Figs. 1, 2, 4, 5, and 6, and in dotted lines in Fig. 3. This shield F is preferably hinged at its rear end to bearings 0 formed on the coupling o of the injector-casing C, and like bearings formed on the shield, by a removable hinge'pintle, c", as shown in Figs. 5 and 6 and in dotted lines in Fig. 4, said shield covering the top of the regenerative pipes and cross coupling 0 its sides projecting downward sufficiently to inclose said pipes. The object of hinging the shield F to the burner by means of a removable hinge-pintle is to adapt the shield to be thrown back 0% the regenerative pipes, as shown in dotted lines in Fig. 1, or to remove it altogether when not needed. In the arrangement shown the light is thrown downward. The position of the shield may be reversed when the light is to be thrown upward or when the burner is employed as a heaterbelow a surface to be heated where it becomes necessary to throw the heat upwardly. In this case the hinge-pintles are formed on the combining-cone D and suitable means provided to hold the shield in position, or the burner may be reversed. A shield, F, of thin sheet metal, is or may also against sudden gusts of Wind.

be provided for the injector and a combiningcone, as shown in Figs. 1, 5, and 6, and in dotted lines in Figs. 3 and 4, said shield being hinged to the same bearings, 0 on the arm 0 of the casing O, or to bearings formed on the combining-cone when the position of said shield is to be reversed. The shield F is closed at its rear end and has a vertical slot, f, for the passage of the pipe E and to admit of its being turned up, and in the top of said shield is formed a hole, f for the passage of the screw-plug 26 of the casing O, as more plainly shown in Fig. 5. As the shield surrounds the casin g, which is heated by the gases or vapors from the regenerative pipes, the air surrounding the burner and drawn into the combining-cone D is also heated, so that the heat radiated from the casing is thus utilized, and air more or less heated is mixed with the gas or vapor, thus promoting the combustion. On the other hand, this shield also protects the flame It is obvious that when the shield F is employed the heat around the regenerative pipes is greatly increased, thereby increasing the regenerative power of the burner, and consequently the illuminating-power thereof. The burner being revoluble, it may readily be adjusted to the direction of the air-currents; but when such shift frequently, as is the case when the burner is used on board of a ship, this attention to the burners becomes laborious. To avoid this, we provide the burner with a directing or wind vane, G, as shown in Figs. 1 and 7, the shield being slotted at its outer end, as shown at f, and on the cross-coupling c is formed a post, g, to which the vane G is secured. The slot f being narrower than the post, the latter serves to hold the shield at a proper elevation above the regenerative pipes. The vane G may be permanently or detachably connected with the post g. In the latter case the stem of the vane fits into a socket in the post and is secured in position by a setsorew, 10, as shown in dotted lines in Fig. 1.

Where the vane is dispensed with altogether, the post 9 may be secured to the shield F, as shown in Figs. 2 and 5.

By providing the burner with a directingvane it is at all times held in the direction of air-currents, so that the flame is not deflected from a line or plane parallel with the regenerative pipes or from a line that would impair its illuminating-power.

WVe have described the shields F and F as applied to a burner of special construction; but we do not limit ourselves thereto, as said devices may be applied to other styles of burners.

To start the burner, a dish, II, (shown in dotted lines,) may be suspended therefrom and a fibrous material saturated with a by drocarbon placed in it and ignited to heat the burner sufficiently to generate gas; or the burner maybe removed from the supply-pipe B, the shields F F and vane G detached therefrom, and the burner heated over a fire suificientlyto generate gas when again connected with the supply-pipe and the supply turned on, after which the said shields and vane may be attached to the burner; or any other mode of heating the burner sufficiently to generate gas may be resorted to.

We do not desire herein to claim, broadly, the'combination of an ejector and a mixing or combining cone with a multitubular regenerator the tubes of which are arranged in a projection of the plane of said ejector and combining-cone, as this arrangement is shown in British patent granted to Roughsedge Wallwork, No. 15,328, of November 24, 1886, and is also shown, described, and
