COOKING sTo'vE AN'D'RANGE.

Application filed May 12, 1924. semi' no. 712,758.

To all whom it may concern:

Be it known that I, Hniinnnr ALEXANDER Tnotirsoiv, engineer, a subject of the King of GreatlBritain, of Wansbeclt Ironworks, Morpetln in the county of Northuniberland, England, have invented a new and useful Improvement in or Relating to Cooking Stoves and-Ranges, of which the following isle-specification,

This invention relates to cooking stoves andranges,particularly ships galley ranges, a ndthe invention has'for its object to provide an improved construction and arrangement thereof.

The-usual type of galley range is fitted with one or more fires with one or more ovens' below the level of what is called the hotplate. We find that with this typeof ranges there are serious disadvantages as the flue gases have tobe carried over the tops of the ovens and down the sides and underneath'the bottom of the same and thence up the back to the chimney.

It is found that with this manner of flue arrangement there is very unequal heating in the ovens with the result that the oven side next thefire invariably burns through and also owing to-the intensity of the fire which has to begkept going on account of the poor heating eifectcontained in the oven, serious burning and damage is caused tothe ring plates for the pots which are arranged on the surface of-the hotplate.

According to the present invention the oven or ovens and the tines thereof together with by-pass fines are arranged or mounted above or'upon the top of the hot plate, so that the flame and gases may come into Contact first with the bottom of the ovenand their ascend around the oven to the chimney or flue. The fire plate or grate is further so constructed and fitted with demountable parts that the rangemay be readily converted for firing with either coal or liquid fueL-asiiiay'be desired. I

The improved range is preferably constructed in the form of right and lefthand units or sections, each complete in itself and consisting of one'fire box, one oven and end supporting legs together with the necessary a is a sectional front elevation of -pla11, 'and plan of the filling in plate shown in Fig. 5.

Figs. 9, 10,'and 11 are respectively front and side elevations and plan of the baillc plate for the bottom of the oven.

The illustrated construction shows a galley -1"ange built up. of right and left handed see tions or units each complete in itself and consisting of one fire box'e one even I), and end supporting legs 0, together with the necessary hotplates(Z andbridge brackets c carrving the horizontal flues e which extend beneath that portion of the hot plate (Z which comes beneath the oven 7), and between the fire, box a and the said le s 0.

Vith this arrangement various methods of assemblying are POSSlblG. for example, the

ranges can be built up with the ovens 7) together and the hot plates (1 outside, as shown, or alternatively the range may he built/up with thchotplalcs together and the ovens at the ends.

In otherpos sible combinations the ranges can be arranged shown with the two ovens together in thecentre and by placin another sin ilar pair baclt to back with the first set,

a surrounding hot plate would thus be ohtained with four ovens in the middle.

Various other combinations of the units or sections can be arranged which allows of great flexibility when installing a'number of the stoves, as they can be set round a Fin building in any suitable form of grouping or if one is first installed additional stoves may be added as required.-

The parts of the stoves or range will be made interchangeable as far as possible, so that the components will be suitable for right or left hand units.

It Will-be seen that the ovens b are arranged on top of the hot plate, or rather on top of the horizontal flue c, which is extended laterally immediately below the level of the hot plate cZ so that an ascending flow of the gases is obtained from the fire boxes at beneath the hot plates d and into the horizontal fiues e beneath the oven Z) whilst the gases continue to ascend up the side flues f r of the oven 7) and over the top by the flue f,

and from thence to the chimney 9.

By using the heat in this manner a much smaller fire can be carried in the fire box, as the whole of the heat is employed in a correct manner by these ascending gases.

The hot plates 03 are fitted in the usual manner with ring plates and apertures for pots.

A single controlling damper h is provided under each oven at the outlet opening h from the horizontal flue e. The said damper it being so arranged that the gases may be directed up the flue atthe back of the oven direct, which will put the oven out of operation, or by reversing the damper by means of its operating rod h the gases will traverse the fines 6, side flues f, and top flue f of the oven. Suitable baflie plates 2' are arranged on the top of the oven in the flue f to direct the gases towards the front of same before travelling back along the top towards the outlet to the chimney g.

The fire box a is shown in Figs. 1, 2, and 3 as arranged for coal burning, being fitted with fire bars 7', the said fire bars, fire door k and bridges being so made as to be easily removable, the arrangement shown is, however, such that all the coal burning fittings except the fire bars 7' and fire door is can be left in position if desired when the fire box is converted for oil firing, in which case, as shown in Figs. 5 and 6, there is substituted for the coal burning fire bars a filling in plate Z which fits into the space left vacantby the removal of the fire bars, the said filling in plate being angled or inclined upwardly at its rear end and provided with serrations or slots m. By this arrangement air can be admitted through the ashpit and by passing under the said plate Z keeps the same cool, and at the same time the air is heated and on passing through the serrations or slots m at the end of the plate Z meets the flame at this point and thus provides a secondary supply of hot air tending to increase the efficiency of combustion.

The filling in plate Z. may be provided, as shown, with suitable ribs n'at'its upper side to act as stifleners and also to form retaining ribs for holding fire clay or other refractory material with which these filling in plates Z should be covered to the level of the top of the ribs to prevent burning of the said plate.

For oil burning a door 0 provided with a suitable oil burner is fitted in place of the coal burning door k of Figs. 1, 2 and 3.

It will be seen that with the arrangements described the fire boxes at oft-he ranges can be converted from coal burning to oil burning, or vice versa, in a few minutes so that in cases-where both fuels are likely to be used at different times the improved construction provides an effective means for carrying this out.

The improved construction of range has the further advantage that it can be converted to another form of range which is usually termed a native hot plate, i. e. a cooking range without ovens as used where cooking is done for Asiatic crews of steamships. To offset this change all that is required is to remove or omit the ovens from the top of the hot plate (Z and fix a chimney direct to the aperture k which is arranged towards the back of the hot plate and forms the inlet to the oven fiues where the latter are fitted.

hat I claim as my invention and desire to secure by Letters Patent is 1. A stove unit for use in requirednumbers in ships galleys comprising a stove structure having a fire box at one end thereof, a hot plate extending over the entire stove structure including the end in which the fire box is situated, a lateral flue immediately beneath the hot plate communicating with the space above the fire box, said hot plate above said flue having an opening at the rear portion of the stove structure, an oven structure fitted directly on the portion of the hot plate above said flue and having bottom, side and top fines about the oven with the rear portion of the bottom flue communicating directly with the opening in said hot plate, a chimney communicating with the top fluel of the oven structure, baflle plates in said fines of the oven structure, and a damper extending in common to the bottom flue of the oven structure and said opening of the hot plate and adapted to direct the products of COIllbUStlOljl either to said bottom flue or to the chimney.

2. A stove unit for use in ships galleys comprising a stove structure having a fire box at one end thereof, a hot plate extending entirely over the stove structure and above the fire box, asupporting leg at the opposite end of the stove for sustaining the hot plate, a horizontal flue communicating with the space above said fire box and arranged between said fire box and said supporting leg, said horizontal flue being directly beneath said hot plate, said hot plate having an opening at the rear portion of said flue, an oven structure placed directly upon said hot plate and having a bottom flue Whose bottom Wall is said hot plate, said oven structure also having side, top and a back flue, said back flue and bottom flue commui'iicating with the opening in said hot plate, a damper pivotally mounted in said oven structure and having its free end adapted to engage either forward or rear edge of said hot plate opening to direct the products oi combustion either to the bottom, side and top lines or directly to said back flue, and a chimney communicating with said back and top flues.
