Figs. 4 and 5 are respectively horizontal andu axial sections showing another form of the in vention.
In the form of invention of Fig. 1, the fuel comprises a simple briquette or block 6 of liquid fuel-absorbent material which may be com-- pressed absorbent material l and impregnated The block is provided with a a witha liquid fuel. suitable air-impervious coating c on the bottom and/ or sides of the block, thus limiting the flame While It to the top of the block, as in Fig. 1. the necessity of illustration requires that the coating be shown in section, it is understood that the coating may be so thin that the thickness cannot be accurately illustrated.
The form of invention of Fig. 3 comprises a; fuel block or briquette 6a of compressedabsorbent fibrous material 7 impregnated with a liquid fuel and having ventilating openings 8a, 8 passing therethrough from the lower part of side faces thereof to an intramarginal part of'the top face.
The block has an air-impervious'coating 9 on the bottom and sides of the block and walls ofthe' 'r openings 8.
Ifthe block is to be shipped or stored, it may bedesirable to additionally provide an air-impervious strengthening and protecting corrugated cardboard l2 adhered on the top'iace of the block and an air-impervious paper It adhered on they bottom'and sides of the block, said coating paper and .board protecting :the block from breakage and'the-fuel fromzevaporation and leakage." Thea board l2 and paper 14 are adapted to be stripped off before igniting the block, leaving said coating 9 thereon to limit the burning to the top of the block. 7
In the form of invention of Figs. 4 and 5 the fuel comprises a tubular block or briquette 6b of compressed absorbent fibrous material 1 impregnated ith a liquid fuel and having a large ventilating axial opening to passing therethrough from the bottom face thereof to an intramarginal part of the top face; and an air-impervious coating 9 is applied on the bottom and sides of the block and walls of said opening.
The coverings l2 and is and openings 8 may be used with the devices of Figs. 1, 2, 4 and 5; and the opening 8b could be used with a rectangular block. Other shapes of blocks and openings could be used within the scope of the claims.
The fuel blo may be prepared in any suitable manner. Or, broadly stated, the method of making the fuel may comprise first forming a block of compressed absorbent fibrous or other material with or without the ventilating openings 8 or Be passing therethrough, then soaking said block in a liquid fuel either under pressure or not, until suificient fuel is therein. Then the impregnated block is immersed in one or more solutions adapted when dried to form an air-impervious coating on the bottom and sides of the block and on the walls of the openings.
Then if desired an air-impervious strengthening and protecting sheet or board may be adhered on the top face of the block; and if further desired an additional air-impervious sheet or layer of paraffin paper may be adhered on the sides and bottom of the block. Said coating, paper and boards protect the block from breakage and the fuel from evaporation and leakage, and the paper and board are adapted to be stripped off before igniting the block, leaving said coating thereon to limit the burning to the top of the block.
A suitable fuel for impregnating the block may be alcohol, or any cheap oil or other liquid material.
A suitable material for the block, may be asbestos fiber, or other absorbent material, or on account of cheapness and its natural burning qualities, may be made up of vegetable fibers, compressed into bales or briquettes, as in Figs. 1 to 5, to economize in space, and to render them slow burning. Such vegetable fibers may be of dried leaves, hay, straw, sawdust, the residual bagasse of sugar cane, and the like.
It has been found that the fuel forming briquettes when made of vegetable matter are porous and highly absorbent, and may be advantageously impregnated with a liquid hydrocarbon, or the like, thus to increase the fuel and smudging capacity of the briquette during protective combustion.
A suitable hydrocarbon fuel for the herein disclosed use is a waste distillate which is the result of refining natural petroleum and other oils, and a suitable distillate for the purpose is that made from the crude oils'obtained from the States of Texas and Louisiana, amongst others, because the waste distillate obtained from refining the crude oils of these States contains a very large amount of sulphur, which when burned, gives off a. sumcient volume of sulphurous acid with the smudge to act upon the plant pests and bacteria to destro them, during the smudging operation.
There are various methods of impregnating the material of the briquette. The loose fibrous material may be first immersed in the liquid distillate, and then formed into briquettes or it may be formed by molding or compressing the fibrous material into briquette form, and then placing the briquette material in a closed container in which is provided a liquid waste distillate and then applying pressure to the liquid.
For forming the coating 9, the block may be dipped into the coating-forming solution or mixture, as far as the top edge of the sides, but so as not to reach the top face. Then the block is removed and the coating allowed to dry. Or if preferred the solution could be brushed or sprayed on the bottom and sides and then allowed to dry.
A suitable solution is sodium silicate or calcium chloride alone or mixed or successively applied, the sodium silicate or calcium chloride providing an element of fire-proofness to the sides. Also albumen or a slurry of Portland cement or fireresistant creosote asphalt emulsion could be used. Various other materials could be used.
For protecting orchards the briquettes may be placed on the ground. at suitably spaced locations and ignited.
For the briquette of Fig. 5, a slightly rough place on the ground is may be found leaving a ventilating space i E to feed the ventilating opening Sb. The b-riquette may be used with or without the control means as described in my said patent. Or something could be used to hold the block up, or otherwise to provide for an air inlet. Any of the described briquettes or blocks may be used for camp fires or in suitable heating or cooking stoves, orchard heaters, tobacco enters or other purposes too numerous to mention.
Various coverings of various materials other than corrugated paper I2 or the paper 14 could be used.
The coating 9 may be omitted at the bottom of the blocks, if desired.
In any case, as the liquid fuel burns, it is drawnto the top of the block by capillary action, and continues to burn until all of the liquid is consumed, leaving the absorbent material in-' tact. The block of exhausted absorbent material a is usually merely replaced by a new impregnated block, but can be reimpregnated and reused if desired.
