FUEL-SAVING GRATIS.

Application filed April 10, 1925. Serial No. 22,166.

To all whom it may concern:

Be it known that I, ALFRED MANSFIELD, a subject of the King of. Great Britain, and a resident of the city of Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Fuel-Saving Grates, of which the following is a specification.

My invention relates to improvements in fuel saving grates the objects of which are to provide means whereby a small concentrated fire can be conveniently arranged in relatively large fire boxes of stoves and ranges, and whereby the fire can be confined in length, as desired.

The invention consists essentially of an auxiliary grate carried upon detachable and adjustable supports, and a vertical dividing plate adjustably mounted transversely of the grate, as will be more fully described in the following specification, in which Fig. 1 is a the invention.

Fig. 2 is a view showing a modified form of pin for the dividing plate.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates the fire box of a stove or range, in which 2 are the grates usually fitted and 3 the fireback having projections l. These projections vary in many stoves and are usually provided to form passageways for draught tothe side of the The numeral 5 indicates a pair of supports of suitable size upon which an apertured grate 6 is carried, and 7 is a dividing plate which is detachably carried upon the grate. The parts thus far mentioned are in a measure similar to those described in patents previously granted to me.

The supports 5 are provided upon their upper edges with elongated slotted lugs 8 extending transversely therefrom, by which they are adjustably connected by bolts 9 passing through apertures 10 in the grate 6. The apertures 10 are arranged in parallel rows longitudinally of the grate and also serve to admit draught to the fire.

The numeral 11 indicates a slot extending longitudinally of the grate, the purpose of which will hereinafter appear. The dividing plate 7 is provided with an aperture 12 general view, partly broken, of-

the grate the plate is held against removal or falling from a vertical position.

As a furthermeans for support the plate is webbed or thickened as at 15 thereby pro-.

viding a relatively broad base to bear upon the surface of the grate. In situations where it is impracticable to turn the dividing plate after inserting it into the slot, I increase the width of the pin transversely of the dividing plate to substantially the same Width as the base of the web 15 as indicated bv the numeral 16 in Figure 2.

Having thus described the several parts of my invention I will now briefly explain its use.

In fitting the grate to a fire box having plain side walls, a grate 6 havingsupports 5 of a suitable size bolted thereto is placed into the fire box. The dividing plate 7 is turned longitudinally of the grate and its pin 13 passed through the slot 11, when the dividing plate is turned transversely of the grate and is moved therealong to the desired position.

When the grate is to be fitted to fire boxes having a fire back or side walls with projections 4 thereon, the supports 5 are adjusted, if necessary, to avoid the projections l, the bolts attaching the supports to the grate being then tightened. The grate is then set in position within the firebox and the dividing plate placed into approximate position and turned transversely of the grate, bringing one end of the plate into place in one of the spaces between the projections. Should the fire box be provided with projections on both side walls which would prevent the turning of the dividingplate, I use a dividing plate having a pin 13 which is not provided with the T head so as to permit of its being lowered vertically into place upon the grate. The fire is then built up upon the rate between the dividing plate and one end of the fire box 1, the apertures in the opposite end of the grate being covered by any suitable means to prevent the flow of air therethrough to the detriment of combustion draught of the fire.

hat I claim as my invention is:

1-. In a fuel saving grate havinga. long itudinally slotted grate member, apair of supports and a dividing plate, said plate having a downwardly extending pin adapted to extend into the slot of the grate to hold the plate against transverse movement.

, 2. In a fuel saving grate having a longitudinally slotted grate member, a pair of supports and a dividing plate, said plate having a downwardly extending pin having a T head adapted to extend into the slot of the grate to hold the plate in vertical position.

3. In a fuel saving grate having a longitudinally slotted grate member, a pair of supports and a dividing plate, said plate having a downward extending pin having a- T head adapted to extend into the slot of the grate, said T head being disposed in. the same plane as the-plate.

Dated at Victoria, B. O, this 1st day of April 1925.
