EUEL ELEMENT EUR vuLcANIzERs.

Application filed August l0, 1918.

T0 all whom it may concern:

Be it known that I, ALPHEUS FAX, a citizen of the United States, and a resident of Louisville, in the county of Jefferson rand State of Kentucky, have invented certain new and useful Improvements'in Fuel Elements for Vulcanizers, of which the follow-- ing is a specification. y

My invention relates to portable vulcanizing apparatus for, application of'patches to the inner tubes of pneumatic tires, or to similar articles which may be patched in such manner, and more especially to such vulcanizing apparatus employing a solid combustible generally of fibrous material impregnated with some highly combustible substance. y

The object of my invention is to provide the fuel or combustible in such a manner that it may be conveniently used 'with various apparatus of this character, and whereby the combustion may be more eti'ective and may more rapidlyheat the patch, thereby economizing in the time and'in the combustible used, as well as performing the vulcanizing operation more effectively and thus producing a somewhat better attachment of the patch.

My invention consists in the new and im'- preved article of manufacture for the purposes just stated, and which article will hereinafter be more Afully described and claimed. y v

In the drawing: l,

Figs. 7, 8 and 9 are further modifications; and i Fig. l0 is a perspective view of the modication of Fig. 9 inverted, and also an approximately correct similar View of theele- Inent of Figs. l, 2 and 3.

It will be understood that combustible or yfuel element may be used my improved with any of the various vulcanizingapparatus designed to employ such solid combustible usually made of heavy paste-board or straw-board impregnated with some highly combustible substance or composition. As representing any of illustrated a rather conventional form in which there is the flat base-plate l, a suitable standard 2 spanning the base-plate, and having a screw r'threaded to run up and down in its middle part over the base-plate, and y'which screw. carries, swiveled to its lower-end, a clamping yoke 4, and is conveniently turned by a thumb-piece 5 on the upper endfof the screw above the standard 2. As is wellknown, the inner tube 6 or other article to be patched is laid across the Ybaseplate undei'the standard 2, which standard in various kinds of apparatus is properly de- .signed to admit 'the article 6 to the baseplate Yl, and they patch 7 placed in the desired posltionfon the article 6, has, as shown in Fig. 1, the pan 8 placed upon it to be clamped tightly thereagainst and thereby clamp the patch 7 tightly against 'the article 6 by the engagement'of the yoke 4 when the-screw 3 is screwed down through the standard 2. The pan 8 holds the fuel or combustible, which is then lighted, and by generates izey the patch to the article 6.

`The combustible or fuel, as ordinarily used, is merely placed on the bottom of the pan 8 in such a condition that it burns practically only upon its upper side. These ythese apparatus, I have f the heat to vulcanpans are suitable for the use of uid or IfY any departure kcallythe saine extent in all from this relation or" the tuel element to the pan took place, it was incident to, some special construction ot the apparatus.

ln my present invention, yl provide a coin-V bustible or tuel element of thegeneral chau acter just alluded to, but make it so that it sustains its lower surface al material distance away from the bottom of the panr 8. Thus. combustible or fuel as shown' lullig. 1, the element 9, which is mainly flat, has pressed down troni its main part, cupped prot-uhse ances 10 at suitable intervals. Merely the bottoms ot these protuberances 10V engage with the pan bottoni, and by tar the. major extent oit the area ot the lower side of the element is raised a distance above thebottoin of the pan approximately that ot the thickness ol the element. I

ln the apparatus shown in Fig.y 2,the parts are the same except that the clamping joke 11 has a depending' riin 12 ywhich engages the tlat platel13 around near the periphery ot" the plate, and whichjplate 13 takes the place ott-he pan 8 resting' directly upon the patch 7 and holding it to the article G under the pressure of vthe yoke 11 as pressed down by the screw 8 in the manner described in connect-ion with Fig.' 1. lily improved combustible or fuel element 9, with its Lkprotuberances 10 resting); uponv the upporsurtace ott the plate 13' and holdingthe lower surface ot the 'element 9 up away from the upper surface oit the'plate 13, thus bears substantiallyr the same relation toV the parts as it does in the previous example;

This fuel element 9 is more fully shown inllig. 3 where it is seen to be provided with pertorations 111 interspersed between' the protuberances 10 Vto facilitate the passage ot air down to or up troni the space between the Jtuel element and the heat-transmitting element, such as the pan 8 and the pl'atel. The modified element 9a in Fig. .4l is like that otligs. 1 to 3, inclusive, but has serrat-ions 1o around its edges. TWith these, even it' the element is placed too iarover to one side oi' the pan 8 or plate 13, so that it engages with one side ot the pan 8 o'r'o't the rim 19 Vot the yoke 11, there will still be spaces in the serrations 15 for the4 circulation of air at that side. Also, Veven it the patch isot practidirections as the interior ot the pan 8 or ot the yoke 11, it may yetlbe forced into the space andits serrations 1t will'yield suiliciently for this and also rleave air circulatinjgspaces around the edges, in additionto the spacesV aorded by thepertorations 14k.v

1n Figs. 5 and 6, the element 9b has modified protnberancesin the torni ot short tongues 16, pressedldown troni openings 17, which thus provide air spaces in a dditio'n to thoseprovided'by the perforations 14, and by virtue ot, which these pertorations 1e may, it desired, be dispensed with.

- bustion ot the entire element.

naeaoe? ln Fig. 7, the element 9C h as lugs formed at intervals around its edges which are turned down to form the protuberances 18. The element has the perforations 14C distributed throughout i'ts interior.

ln Fig- S, the element 9d is simply transversely corrugated throughout its length and has the pertorat-ions 1e suitably distril ut'ed. rEhe' alternate corrugations 19 thus :torni the protuberances that support the intervening surfaces away tromthe plate or pan upon which the combustible or 'heating element' Tests.

rllhe element 9e et F 9 has its protuberances 2O 'formed as separate pieces and suitably secured to the tlat niai'n part i1,

which has the pertorations le. The appearance ot the under side ot this tlat main part 21 with its att-ached protuberances '2O is indicated in Fig. 10. lt :will also be understoodV that where the protuberances Vare pressed down in the torni ot' cups, as the protuberancoslO ot' Figs. 1 to 1, their bot'- tonis will appear substantially as the protul berances 2O shown in Fig. 10.

All ot the examples are shown as provided with the periorations 14; but it will be understood that these are not essential elements ot my invention. They are preferable because they kperniit of 'more thorough coni- They are ot use even though the lower side of the ele nient rested directly upon the panV or plate that conducts the heat to the patch. `When the lower side of the combustible elementis elevated so that there can be substantial coniq bustion on the lower` side, these perforations perinit of afbetter dra-tt in adjacent parts of the combustion space and a more thorough distribution of the .combustion throughout the body ot the combustible. portant object o niy'invention is to insure this combustion on the loiwerside ot the element by means embodied in the element itself, so that this kind ot yulcanizing operation may be employed even though the apparatus `available is not particularly designed for' any but the ordinary use of the combustible elementlying liat upon the upper surface of the heat-conducting;element. llVhere the combustible element is used in this ordinary way without permitting the proper combustion on the lowerside, but relying upon the combustion taking `place on the upper side of the element, the heat trans mission to the patchisvery indirect, and it may be said that there is direct transmission of heat trom 'the coin ustible or tuelthrough Yso But the iin- Y the plate or pan from the patch only during cally all of the operation, is tar more eective and economical and saves considerable time; and by providing a fuel element which is adapted to assume this relation toward the parts of practically any kind of apparatus of this general character without any special attention on the part of the operator, the advantages alluded to are further in creased. l/Vith the corrugated element 9d of Fig. 8 it is not even necessary to observe which side is placed downward, as it has the protuberances 19 extending in both directions. The other examples may also have oppositely extended protuberances if desired. v

Various kind of protuberances are illustrated, and it will be understood that any of these, or others which are equivalent, may he used singly or in combination in the same element; and that my invention is otherwise susceptible to considerable modification as may be dictated by requirements. Accordingly, while certain constructional details are deemed preferable in connection with my invention, and I have shown and described these rather specifically in elucidating the construction and use of my invention, as is required, I do not wish to be understood as being limited to such precise showing 'and description, but having thus fully described my invention, what I claim Copies of this patent may be obtained for ve cents each, by addressing the as new and desire to secure by Letters Pat- A ent is:

l. As a new and improved article of manufacture, a fuel element for use in a vulcanizer, comprising a main part with a relatively widely extended lower surface, and a plurality of protuberances extended from said main part to bear upon a suitable object to be heated and support said element thereon with said main part exposed a suitable distance away from said object to permit adequate combustion of said element on its side adjacent to said object.
