PORTABLE VULCANIZER.

lar to the portable type constitutng a handy repair kit by means of which punctures in inner pneumatic tubes for vehicle tires ma'y be readily and quickly mended.

The invention comprises essentially a fuel holding element consisting of a metallic pan carrying at one side a vulcanizable substance or patch and at the other side a heatsupplying substafce and' a clamping means for holding said element in position upon the' tube to be repaired. 4

I am aware that devices of this general type have been proposed heretofore and it is tages which arise in the use of these that my invention has been evolved. For example, some difficulty is experienced in the manipulation of vulcanizers of this Construction 'nn obtaining and maintaining proper disposition of the vulcanizable material or the mem ber carrying the same while the clamping instrumentalty is arranged 'in operative relation to hold said material exactly over the desired point of the puncture. This is eliminated in my device by reason of the fact that the patch carrying element is removably held by the clamping member so .that in Operating the latter the patch is easily disposed where desired. Again, inperforming vulcanizing processes of this character it .is very desirable to apply whatever heat is required only where it is needed; in other words, the cured material of-the vehicle tube should not be unnecessarily subjected to heat as the tendency-is under such condition to destroy the life of the rubber.

, Now, puncture's in pneumatic tires are either small mnute openngs, or where more serious they are of elongated form, slits, and

ber tube so that they are found to occur transversely at times, longitudinally or diagonally with respect to the tube at other times. Therefore, it has been my aim to arrange in my device for the use of a patch o f the desired elongated form and to provde clamping means with pressure' elements which coperate with the fuel holding means so mounted that said holding means may easily be shifted to the proper angle and over the opening of the tube. On theother hand if the holding means for the inflammable material is of circular or other form than the elongated, so as to'be of sufiicient size to take care of the' vulcanization of a rupture of greater or less serious character, or, if said holding means is stationary, 'the very di'sadvantage above referred to, of subjecting portions of the tube surrounding the puncture to unnecessary heat results.

For a full understanding of the present invention, reference is to be 'had to the 1501- lowing description, and the .accompanying drawing, in which:

Figure 1 is a side elevation of a device constructed in accordance with my invention.

Fig. 2 is a top plan View thereof.

F ig. 3 is a bottom plan of the overhanging arm with the fuel holding-means in position upon the pressure device, carried by said arm.

Referring to the drawing, the vulcanizing device consists of a base 1 preferably of circular configuration and of a suitable size to support a portion of a rubber tube, as indicated at 2 when performing the vulcanizing process upon the^sa r ne. At one side the base is provided with an extension 3 to which is pivotally connected at 4 an overhanging arm 5 terminating at its extremity in a slot 6 extending longitudinally. -Diametrically opposite to the extension 3 is a forked extension Specification of Letters Patent.

so y,

7 suitably slotted to receive the end of a clamping the arm to exert pressure in the manner hereinafter described. Depending from the central portion of the arm 5 is a fixed post 11 to the lower eXtremity of which is freely swiveled the pressure member 12. This latter element comprises a pair of opposite relatively long arms 12' and a opposite relatively short arms 12" all of which excepting one of the short arms only are preferably fianged as indicated at 13.

With this clamping means I employ a fuel holding device which also performs the further function of holding the patch or vulcanizable material. Said device consists of a shallow metal pan 14 which is provided with an annular laterally projecting fiange 15. The fiange referred to performs a dual function in that it acts as a cooling ange permitting the pan to be readily handled when in heated condition and also acting to support said pan when engaged with the flanges 13 of the pressure member 12. As

indicated in Fig. 1 the pan is suitably inserted laterally of the member 12. The surface of the bottom of the pan has preferably attached thereto vulcanizing material 16, uncured gum, and at the other side within the pan is provided an inflammable substance 17. This latter may be cardboard impregnated with some infiammable material which will burn without flame preferably, and yet supply suficient heat for performing the vulcanzing process.

The use of the inventon will easily be understood from the foregoing description,

` it being only necessary to dispose 'the vehicle tube upon the base 1 with the puncture arranged substantially centrally of said base. The arm 5 is then moved downwardly until the fuel holding member with its vulcanizable material rests uponthe punctured portion whereupon the clamping member 8 is engaged with the arm and sufficient pressure exerted against the fuel holding device to obtain the desired result. The fuel substance 17 is then ignited and the process of vulcanization 'carried out in this manner. The advantage of the swiveling of the member 12 isevident because the fuel holding pan with its patch may be disposed at any v angle conforming to the angle of the rupture of the tube and the fact that the holding means is movable with the arm 5 which sustains the same, makes it extremely easy to obtain the exact position of the patch upon the tube.

The foregoing device is designed to be placed within a suitable container with a supply of several fuel holding means with patches'and inflammable material arranged thereon, this formig a convenient kit for carrying about with the vehcle for use at any time required. The'pan 14 is 'designed to be of cheap material so thatwhen once used it may be easily discarded and the-propair of v mesme vision of the cooling flange 15 enables said pan to be displacedfrom the member 12 when it has performed its function in the.

the base at one side, a support depending' from the arm, pressure arms mounted on said support, and adjustable with respect to the 'part to be vulcanized preliminary to application of pressure ther-eto, a vulcanizing member engageable by said arms, and clamping means at the other side of the base operable to impart clamping action when the operative vulcanizing position has been determined by the arms aforesad.
