Year: 1889

page_text: Date of Application, 7th Sept., 1889
Complete Specification Left, 28th May, 1890-Accepted, 12th July, 1890
PROVISIONAL SPECIFICATION.
Improvements in Grates or Furnaces.
We, ALESSANDRO PICASSO, Sea Captain, and GIOVANNI PETERS, Engineer, trading
under the name of Peters and Company, of Rue St. Luca 3b, Genoa, Italy, do
hereby declare the nature of this invention to be as follows:-
The admission and uniform distribution of atmospheric air beneath the grate of
furnaces of any construction, ensures perfect combustion, as has been demonstrated
both theoretically and by experiments by scientists such as Messrs. Peclet, Valterios,
Morin, etc.
The improved grate shown in end elevation and side elevation in Figs. 1 and 2 of
the accompanying drawing, consists of the bars G (shown in longitudinal and
transverse section on a larger scale in Figs. 3 and 4 of the drawing) which are made
hollow at O, and perforated alternately on the sides with holes I. The supports E of
the bars are also hollow and provided with an opening or slot S serving for the escape
of the ashes which in course of time may find their way therein. A plate C of V-form
(see Figs. 1 and 2) divides the ash-pit of the furnace A. On this plate rest the
supports E. Through the holes n passes an iron bar which serves to connect the
bars G. H and F are the supports of masonry.
Operation of the apparatus. Atmospheric air enters through the hollow of the
supports E and passing through the hollow O of the fire bars G of the grate is
distributed beneath the fuel through the holes I.
The invention consists in fire bars and supports made hollow for the circulation of
air, of no matter what form, and applicable to grates of any shape and of any
construction.
Dated this 7th day of September 1889.
