NE-HALF To FRANK W. FRAME, oF Los FUEL-PAoKAeE Application sied 'october 2s, 191s.

To a'ZZ 'whom t may concern.-

Be it known that we, CHARLES S. SPURR and HERMAN P. RANDALL, citizens of the United States, and residing at Los Angeles and Pasadena, respectively, in the county of Los Angeles, State of California, have jointly invented new and useful Improvements in Fuel-Packages, of which the following is a specification.

This invention relates to fuel packages or vulcanizers and the like, and for such a vulcanizer as is shown in our co-pending application Serial No. 234,7 20, filed May 15, 1918, The fuel package described and claimed in this present application has also been described in said co-pending application; but is not the subject matter of the claims of said co-pending application, said lclaims being directed to the vulcanizer itself.

It is an object of the present invention t'o provide a fuel packet, which will, in convenient, adaptable and easily handled form, provide the desired fuel charge for a vulcanizer. lt is further an object of this invention to provide a fuel package in' such form as to be easily insertible in the vulcanizer; and while the present described fuel package is not at all limited to the particular type of vulcaniz'er described in our co-pending application, yet it is particularly suitable for that use.

`Her`etofore it has been the practice to provide what is called a vulcanizing packet, comprising a plate with a vulcanizabl'e rubber patch attached to one side and a bodyA 0f fuelatt-.vched to the opposite side. This body of fuel has been commonly a cake of porous material, such a`s cardboard or strawboard which is impregnated with combustible substances. An object of our invention is the formation of al Separate fuel package which is not necessarily permanently attached to a plate, and not necessarily a part of a vulcanizing package, but which is in such form as to be easily placed in a vulcanizing pan; and which, withal, may be easily and cheaply manufactured, and will give eflicient and positive results upon its combustion.

The invention will be best understood from the following detailed description of a preferred formation of fuel package; reference for this purpose being had to the accompanying drawings in which- Figure 1 is a vertical longitudinal section Specification of Letters Patent.

showing a typical form of vulcanizer with our fuel package placed therein; Fig. 2 is a perspective of vour fuel package, the top being broken away for purposes of illustration; and Fig. 3 is a transverse section of our fuel package, l

In the drawings we illustrate a vulcanizer apparatus which comprises essentially abase 10, a clamp yoke 11, a 'clamp screw l2, `a spider 18, and a pan 14 carried by the spider. The tire tube or other piece of rubber wished to be vulcanized 'is illustrated at 15; it is placed upon the base l0 and the pan 14 is clamped down on the rubber or other vulcanizable patch 16, which is placed over the ruptured part of tire 15. Pan la may be made of a suitable heat conducting material, and, in the particular form of apparatus herein shown, may be made of heavy copper or steel, the pan being a perF manent part of the apparatus and not dis= carded aft'er cach vulcaniz'ing operation.

The bottom of the pan is preferably confcave, as is shown in the drawings, so as to more or less accurately lit upon the upper convex surface of the patch 16. Such pans, and also the patches, are usually oval in plan, and the bottom of the pan isconcave both longitudinally and transversely. Our fuel package is made to t the pan.

The fuel package is shown at P and comprises a container' having a bottom part 20, a top part 21, and afilling 22 of some proper fuel. This fuel is preferably a substance, or mixture of substances, capable `of autogenou's combustiona slow y burning powder. The materia ls of the powder (such as sugar and saltpeter) may' be miredV tcgether in proper proportions and preferably miXed in granulated form; the loose mixture beingmerely put into the bottom part 20 of the container and the top part 21 being put into place afterward. The container will hold a certain measure of fuel; and thus the heat value is easily regulated and made uniform for all such packages. The vcontainer itself is preferably made of some combustible substance, although we preferably intend not to make it of a substance having any large heat value; being merely a container which is inflammable, and hence eliminating the necessity or bot-her of the user removing the cover in order to light the fuel. The user thus has a fuel package in which there can be no variation from standard heating value, and no waste of fuel. The fuel is not eXposed to the wind. The container, for instance, may be of strawboard, cardboard, or the like.

And it is also preferably of such a substance as will burn with very little or no flame-fsuch a substance as will char rather than burn with a flame. Certain grades of soft and inexpensive wood pulpfcardboard, etc., answer well for this use; but any special and suitable substance may be used; and if necessary, for the purposes herein set forth, a cardboard or any other material of which the container is made may be impregnated either with a substance to make it more combustible where it is very hardly combustible, or may be impre nated with a substance to make it more s owly infiammable where it otherwise would burn quickly or burn with flame. Ordinary materials which might burn quickly and `with flame, may be impregnated with mineral substances, as with a silicate.

When it is desired to effect a vulcanizing operation, the apparatus is put in the position and arrangement shown in Fig. l, a fuel package having been placedV in the pan as indicated. The fuel package is then ignited by igniting the outer container. For the purposes of readily igniting the container, the top, or a portion of the top of the container, (being that part which is eX- posed and readily ignited with a match or the like) may be especially treated with some readily oxidizable substance, (such as a solution of saltpeter in water about one to three) so that it will readily be ignited with a match. However, in the ordinary case, a cardboard, strawboard or" the like, may be selected which may be easily enough ignited, and which at the same time will burn with little flame. When the fuel package is consumed, the charred container, neXt the walls of the pan, keeps the burned fuel from sticking to the pan; so that the burned matter may then be easily discarded by merely inverting the pan.

The container may preferably be formed with its bottom 2O concave both longitudinally and transversely; or the bottominay be originally formed fiat and forced into the concave shape `illustrated when itis` placed upon the concave bottom of the pan. Preferably the top and bottom parts of the container are made to fit more or less tightly so that the parts will not fall apart, without necessitating the use of any adhesive or the like; and the Whole package may be made to fit the pan more or less snugly, but not` ing a thin flat container of cardboard, and

a filling of slov\T burning fuel.

4. A fuel packet for vulcanizers, embodying a thin flat container of combustible material and a filling ofa substance autogenously combustible.

5. A fuel packet for vulcanizers, embodying a thin flat container of combustible material, and a filling of a substance `slowly autogenously combustible.

6. A fuel packet for `vulcanizers, embodying a thin flat combustible container, and a filling of a slowly autogenously combustible substance in comminuated form.

7. A fuel packet for vulcanizers, embodying a thin fiat box-like container ofslowly combustible card-board, and a filling of a slowly autogenously combustible substance in comminuted form.

In witness that `weclaim the foregoing we have hereunto subscribed our names this 15th day of October, 1918.
