SWITZERLAND, A CORPORATION OF BURNER non METALDEHYDE.
Application led July 19,.
To all fw lao/n 1, t may concern.'
Be .it known that I, CARLO ToMMAsi, a sub-` ject ojl' the King oit' Italy, and 'resident ot' Basel. Switzerland, have invented a new and useful Burner for Metaldehyde, ot which the 'tollmvinn` a full, clear, and exact speciliration.
A drawback ol: all known brufners 'for inetaldeliyde consists-z in the tact that after a long burning the burner becomes so hot that when the :Elaine is extinguished a troublesome emission of vapors Otacetaldehyde resulting` 'from the depolyn'lerization ot the inetaldehyde takes place and thus causes losses ot' fuel. IThese inconveniences. are avoided by the burner oi' the present invention wherein the Walls oi' the burner, `surrounding `the metaldehyde, that is fto say subjected to heating by the flame are provided with a means 'for cooling them by a liquid. Generally it s suflicient to cool'the support of the body ofsolid fuel.
In Figs. l and 2 of the annexed drawing there are shown in vertical section tivo eX- amples of burners carried out according` to the invention.
In the example of Fig. 1 A designates the support of the body B of solid fuel. `which is supposed to be a pastil of inetaldehyde. The support A is hollovv yand is iilled with a cooling liquid as for instance Water, glycerin7 an aqueoussolution, etc. In order to take into consideration the expansion of the liquid under the influence of the heat, the vessel formed by the support A can be pro-` vided at its top with an orifice a or it is not entirely filled up with liquid, leaving thus an ail' cushion (l .in the upper part of the slq'iport.
Fig', 2 shows a bllirner with aprotectingr sheath receiving: the body ot metaldehydc li, This |noteotingisheath 72 terms a part ol vessel A filled with Water provided with an orifice a and enclosing' an air cushion (l. The inetaldelrvde body B is pushed auto niatically dpivard by a spring` D against a wire E fixed on the top oi the vessel A and limitating the protrusion of the inetaldehydc body B from its protecting sheath b.
I am aware that the cooling of a candle sliding-tube by a Water container in order to keep the candle cool and to avoid Wast- .ing of the said. candle is already known and 1921. Serial N0. 485,923.
that it has also been proposed heretofore to place a caiulle in a Water bath. keepingr the candle floatingI and causing it to rise autoA niatieall y as it burns oli", in order to keep the candle iiiractically at a constant level.
But pri-yviously to the present invention nobody had proposed a liiurner `for nietaldebyde in which the burner walls surrounding the inetaldehyde Were provided With la` means for cooling them by a liquid in order to prevent the depolymerization of the Inetaldehyde after the extinction of the llame.
IVhat I elaini is:
1 l. A burner for inetaldehyde wherein the `Walls of the burner surrounding the metaldehyde are provided With a means :lor coolin` them by a liquid, in order to prevent the depolymerization of the metaldehyde.
2. A burner for metaldehydecomprising a hollow support `for a metaldehyde body of the said support containing a liquid, in order to prevent the dcpolyrnerization of' the nietaldehyde. 1
3. A burner for Inetaldehyde comprising a hollow support for a metaldehyde body, the said support containinga liquid in order to prevent the depolynierination of the metaldehyde and being` provided at its top with an orifice.
at. A burner for nietaldehyde comprising a protecting' sheath for a body of Inetaidehyde, the said sheath being` a part of avessel surrounding it and containing a liquid, and a spring pushing the said body upwards against a Wire fixed on the upper part of the said vessel and liinitating the protrusion of the said body troni the said sheath.
5. A burner for solid fuel comprising a protecting' sheath for a body of metaldehyde, the said sheath being a part of a vessel surrounding' it and containing a liquid an d provided ivith an orilice at its top and a spring pushing; the said body upwards against a `wire xed on the upper part of the said vessel and liinitating the protruson of the said body from the said. sheath.
`In witness 'whereof I have hereunto signed my naine this 27th day ot June, 1921, in the presence of two subscribing Witnesses. n CAR-LO TOMMASI. litnesses Tunon KURZ, ORMAND Rir'rnn.
