This invention relates to improvements in a fuel unit of the type formed of waste material; that is, sawdust, wood shavings and the like which is combined with a suitable fire-sustaining 5 binder. An object of this invention is the provision of cut into blocks and the cylinders into shorter lengths and ñnally the said blocks and short length cylinders provided with a wick to facili tate lighting thereof. Specifically it is proposed to utilize a mixture 5 in the ratio of l lb. of parañin wax to 21/2 lbs. of a fire aid or wood kindling that can be more finely divided wood; that is, sawdust, wood shav readily utilized than the like substances hereto ings, ground wood or shredded wood. Substan tially this same ratio will obtain if tallow'is used as well as with the paraffin oil and vegetable or 10 fore produced. 10 (C1. 44-41) Another object of this invention is the provi sion of a fuel unit which is composed of saw dust, wood shavings, shredded wood or the like combined with an infiammable binderthat can be readily used out of doors byr campers and the like and which can be readily lighted without animal glue. The/paraf-Iin wax, tallow and glue wouldä be mixed with the Wood while the same are hot and in a liquid state. This mixture is then turned into a mold which would produce _ forming a part thereof and it is to be understood that any modifications may be made in the exact either the sheet I0 shown in Fig. 3 or the cylinder l” II shown in Fig. 4. At I2 in Fig. 3 is illustrated the cross-section of the sheet while at I3 in Fig. 4 is illustrated the cross-section of the cylinder. The sheet lo is then divided into mocks or st/icks along the dotted lines I4 and I5 while the cylin der II is divided into shorter -lengths indicated by the dotted line I6. The dividing of the sheet I0 in accordance with the dotted lines I4 and I5 results in the final 25 structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the form of a block or stick I‘I shown in Fig. 1. The 25 cutting of the cylinder II at the dotted lines I6 results in the form I8 of Fig. 2, there shown as danger to the user and which will burn or sus tain ñre for a considerable period of time con sidering the size thereof. Other objects and advantages of the present 20 invention should be readily apparent by refer ence to the following specification considered in conjunction with the accompanying drawing invention. 30 having a flat base I8a on which it readily stands Y In the drawing: upright, and as being provided centrally thereof Fig. 1 is a perspective view of one form of the with a wick I9. It should be understood at this 30 time that while the block or stick I'I of Fig. 1 is not illustrated as having a wick therein said block could readily have the wick supplied thereto. The method of manufacturing the form of the invention in Fig. 2 consists in placingthe initial mixture in a suitable mold for forming the cylin der I I and then cutting the cylinder into shorter lengths. These shorter lengths are` then pro vided substantially along the .axis thereof with a hole or aperture 20 through which the wick I9 is drawn. In order to facilitate the threading of the wick I9 through the hole or aperture 20 the said aperture may be slightly larger in diam eter than the wick. The wick is then sealed in fuel unit; . Fig. 2 is a second form thereof; Fig. 3 is a plan-sectional view of the formation from which the final form of Fig. 1 is cut; 35 Fig. 4 is a side elevation-sectional view of the formation from which the form in Fig. 2 is cut; and Fig. 5 is a cross-sectional view through the form illustrated in Fig. 2 as seen from line 5-5 thereon. c Throughout’the several views of the drawing similar reference characters are employed to de note the same or similar parts. Briefly this invention pertains to the mixing of 45 sawdust, shavings. ground wood and shredded wood with either parañin wax or tallow and sub jecting the said mixture to a pressure suitable to cause same to have a close-grained texture. In stead of mixing the wood parts with paraffin wax 50 or tallow the same may be mixed with paraffin oil and either a Vegetable glue or animal glue and then the mixture subjected to a pressure and allowed to cool. This mixture would be made up either in sheets lor relatively long cylinders and the sheets then position by the application of molten paraiiin wax or the like around the wick at the upper end 2I and the lower end 22 thereof. It is, of course, understood that the entire aperture 20 may be filled with the molten wax around the wick I9 after the said wick has been placed therein but 50 it is suflicient if the wick be merely sealed there-v in by the wax rings 2| and 22 sinc'e after the candle I8 has been once lighted and is then ex tinguished there will be sufficient molten wax on the upper end of the candle to solidify into a 55 2 2,107,054 sealing ring upon extinguishing of the flame. 'I'he form of the invention illustrated in. Fig. 1, or the blocks or sticks I'I, will be` utilizedfor starting fires in normal fireplaces, such as grates, stoves, furnaces and the like and for igniting the usual fuels burned in such fireplaces. The form of the invention illustrated in Fig. 2 will find its - greatest use with campers and for temporary out door fires by being placed between suitable up 10 rights on which cooking utensils or the like may be placed. It is, of course, understood that the candle form I8 may be employed in the normal fireplaces for igniting heating fuels, while the blocks or sticks Il could be utilized as fuel for 15 out-door fires. By providing the form I8 and sup plying same with a Wick it can very readily be lighted and then stood on end, as it has a sup lng, but are not cleanrto handle, and may be dangerous because they are too highly inflam mable; in addition to the too rapid burning which makes them ineffective because they are con sumed before they fully ignite the other fuel, as above explained. My composition, in substan tially the proportions mentionedyof sawdust or other wood substance or like fibrous material, and paraffin or like material which is clean for handling as well as cleanly burning without of fensive odor or danger of explosion, can be inex pensively produced, since the sawdust, for in stance, is a by-product of lumber mills,‘and the paraflîn, for instance, may be the crude scale which is a by-product of oil refining. It is thus 15 practicably produced, is entirely practical, safe and effective in use, and is commercially profit porting base, and allowed to burn across its en able so that its widespread use may be a real tire cross-section -progressively from its top end downward. Due, however, to the materials, namely the wood content of the unit i8, a much hotter fire is provided which will have greater benefit both to the users and to those who have usefulness for campers than the tallow candle. Also due to the fact that the entire upper surface will burn at one time instead of merely the wick supplying the flame and the tallow the fuel for the flame, the unit affords a much greater heat producing effect than is had in a candle. It has been found that the unit I8 having the dimension 30 of 11/2 inches in diameter and 3 inches in length will supply a hot flame for a period of forty-five not by-products and therefore too expensive, but minutes. lI'his property of supporting a relatively slow such by-products for disposal. These advan 20 tages are not attainable with compositions call ing for proportions of other substances which are which render the use and operation of the ma terial less satisfactory as above noted. and pointed out its advantages over compositions of the prior art when made up in suitable units ’ substantially as set forth, what I claim as new and desire to secure by Letters Patent is: l. An article of manufacture, a fuel unit or kindler consisting substantially of an admixture of finely divided wood and paraffin, in the ap steady combustionthroughout a side on which it proximate proportion of 21/¿ to 1 by weight, com is ignited, from the initial surface inward, with pressed into a cylindrical shape having a diam- ‘ an effectively hot flame yet without a too rapid exhaustion of the fuel substance is of value when the unit is used as kindling for other fuel, as compared with fuel units having either a pre 40 ponderance of the less inflammablefibrous ma terial, in which case the combustion cannot be relied upon to continue until the fire is started, or with units in which the highly inflammable material is in too high proportion, in which case 45 the unit burns up too quickly, and for that rea son does not start the fire. When used as kin dling, the unit may be ignited on one or more sides, and on each side that is ignited there will be a relatively slow steady combustion all over the surface of the side or sides, so that a com paratively small block of the substance is suffi cient for starting a ñre in a household furnace or the like, with certainty that, once ignited, the fire will start without further attention. I am aware that other fuel compositions have been provided, either wholly or almost wholly of wood über or other fibrous material, or else 25 Having thus disclosed a preferred composition , eter and length whereby the unit or kindler is provided with a supporting base at one end of the cylinder and may be stood upright thereon, said cylinder having an aperture extending the length thereof, and a wick in said aperture and project 40 ing above the upper end of the cylinder whereby the unit or kindler may be lighted and, due to the composition of said cylinder, whereby the fire is confined to the upper end of the cylinder. 2.
