. In Germany February 9, 1949 [The invention relates to aportable vulcanizing apparatus of comparatively small size, which is suitable'for transport in vehicles and enables the j'user of the vehicle to repair damage to the tires at any tim on the journey by a reliable vulfcanization. 7 Q V 'l It, is known that the vulcanization of rubber must take place under heat and pressure at a determined medium operating temperature. Vulf ca'nizing' apparatus have been proposed which press the patch to be vulcanized between clamp- ,ing surfaces and are fitted with a heating de- ...vice. Usually, however, the upper clamping surfaceof the apparatus is heated and constitutes a. container which is intendedfor the reception ,ofliquid fuel. It difiicult in such apparatus :with variations in outside temperature to keep the operating conditions suitablefor vulcanizaftion. 'Moreover, they involve a comparatively ,ierge consumption of fuel because the flame heat of -th heatingapparatus is not used, and are also inconvenient in use and to service. h The apparatus according to the invention removes these disadvantages. It consists of a heatable press with a horizontal clamping surface and is characterized in that the lower clamping surface is constituted by the top cover of a pot-like container for the receptionof the heating device. In this case therefore, the lower clamping surface is hot. Preferably the heating is: effected by means of a burner fitting into the pot-like container and which .is operated by a cartridge of solid fuel,such for'exa'mple as resin, spirit, or the like. Such fuel cartridges develop a medium heat, particularly suitable for the operation of vulcanizing apparatus, and can be adf'justed not only to the size and thermal reguirements of the apparatus to be heated, but can-ifneed-be adjusted in depth in the burner sc tha t it is possible to regulate the heating without use of control apparatus in such a way that a constant operating temperatureis achieved, de-

spite changes in external temperature.

The heated lower clamping surface can be remov edfrom this container in order toachieve quick cooling of the apparatus. It is conveniently depressed from the edge towards the center, so that the parts to be vulcanized come under higher pressure at the edge and run out thin. The upper clamping surface ispreferably a flat plate attached to an adjusting screw, the thread of which engages in a bracket extending upwardly from the lower clamping surface. In order to facilitate introduction and removal of the parts to be vulcanized, this bracket can be 3 Claims. (01. 126-43) ensured.

pivotally mounted on the pot-like lower part of the apparatus s that the upper clamping plate and bracket can be swung to the side. Conveniently, th upper clamping surface is mounted so that it can tilt to a limited extent in all directions and take upan inclined position so that a uniform'transfer of pressureto the whole surface ofcontact of the parts to be vulcanized is Y The drawing shows examples of construction of the vulcanizing apparatus according to the invention,

Fig. 4 is a longitudinal section through the movable lower clamping plate of this apparatus, Figs. 5 6 and 7 show the associated burner in side elevation and in front elevation and in clamping surface I consists of a plate 3 having a connector 4 which is removably fitted to the upper end of a pot-like container 5 which forms the base of theapparatus and receives a heating device.

constitutes a bearing for a pin I3 0n the bracket,

The container is provided on opposite sides with air inlet openings 6, and has at the front an opening 1 for the insertion of a burner which is supported on a floor 9 raised above the lower edge 8 of the apparatus, and the burner has a projection floor.

The container 5 has a rear extension I I, which which fits in a hole [I] in the I2, which is pivotally mounted in the extension 'I I. The head I4 of the bracket I2 supports the .upper clamping surface 2 and is provided with anadjusting screw I 5, .to which is fixed the upper clamping surface 2. which is constituted by a fiat plate Hi. The connection between the screw I5 and the plate I6 is such that the plate has a certain freedom of movement and can be inclined to some extent in all directions. The upper clamping plate 2 is completely plane, while the center part of the lower clamping surface I is depressed somewhat below its rim (Fig. 4). When vulcanizing a patch, for example on to a vehicle tire, the rim of the patch is subjected,-

screw and the plate [6 attached to it can be.

swung to the side (Fig. 3), so that the lower clamping surface I is readily accessible for carefully laying on it the parts-to be vulcanized.

The burner to be used in this case consists;

as shown in Figs. 5-7, of a fiat sheet 19 which carries a socket 20 of rectangular section for reception of an elongated fuel cartridge 2| of resin, spirit or the like.

the under surface of the plate l9 fits into the A projection 22 on- 4 42 of the upper clamping surface 4| being movable in the head.

The invention is not limited to details of construction of the apparatus. Instead of a bracket with adjusting screw, other means can be used ,for, pressing the upper clamping sur-' face, for example the upper. clam-ping surface can be pressed down by a spring or by means of va device similar to a beer bottle capper. The upper clamping surface can also be stationary and the'lower clamping surface so constructed that it can bemoved against the upper clamping 'sLufaceei-ther 'alone or together with the container.

Having now particularly described and ascertained the nature of our said invention and in what manner same is to be performed, we de- "clare'that what we claim is:

centering hole I0 of the apparatus. The burner.

also comprises a lever 23 constituting an adjusting lever and pivoted at 24to an upward projection 25 on the sheet [9, which passes through the socket 20 and which constitutes a spring engaging with teeth 26 of a member 21. On the member 21 adjoining the teeth 26 is a scale corresponding with the external temper- The end 28 of the adjusting lever is bent into hook form and constitutes a hand grip by means of which the burner can be gripped. V

The fuel cartridge 2! rests loosely in the socket 20 and is supported at its lower end on the adjusting lever 23. According to the position of this lever the cartridge projects toa greater or lesser extent from the upper edge 29 of the socket 2c. The projecting upper end of the cartridge is intended in use of the apparatus to provide heat appropriate for an operating temperature of about 140 C. If the apparatus is very cold, as in winter, the lever 28 is engaged with the top teeth so that the cartridge 2| projects to a maximum extent from thesocket 20, while in summer, or when the apparatus is warm, as a result of previous use, the lever 23 is pressed down so that the cartridge projects only to a small extent. When the cartridge has burned down to the upper edge of the socket 20, it burns only with a moderate flame, which is sufiicient to maintain the operating temperature necessary for vulcanization] In order to maintain the required size of flame, cut-away portions 30 are formed in the upper end of the socket 20 and serve to admit'the necessary combustion air to the cartridge.

Fig. 8 shows a particularly'small form of apparatus. In this case the lower clamping surface 31 is in one piece with the container 32. The container has on opposites'ides air inlet openings 33 and a front opening 34 for the introduction of a burner 35, which is provided with a fuel cartridge 36 of resin, spirit or the like and has cut-away portions ;31, inits end. The container 32 is constitutedon the lower end of a rigid bracketSS which alsoconstitutes the base 39 of the apparatus and has a head 40 engaging the upper clamping. surface, thescrew 1,..Foruse with a vulcanizing press including a base member with a central depression, a burner including a sheet having a depending projection receivable in the depression, a vertically extending socket tube secured on said sheet and including diametrically opposed longitudinal slots, a spring arm pivoted for verticalmovement at one of its ends on 'saidsheetand extending through said slots, an upstanding .bar on said sheet adjacent said socket tube, vertically spaced teeth on said b'ar for retaining said spring arm in vertically adjusted position, and an elongated fuel cartridge received in said tube socket and resting onisaid spring arm.
