(clins-_18)` ` . ` I . i i 2 1‘ i This invention relates Ito a tube vulcanizingde vice for pneumatic tires, and has for its principal object the Aprovision of a simple, compact, and highly eñìcient .tube plate vulcanizer which will on each of the sleeves >I2 and extends forwardly thereof, to a tubular extremity 45 having a hori-` accommodate one or more tube repairs simulta zontal attachment flange I6 at its bottom. neously; which will accommodate exceedingly long repairs in the tube; and which will apply a uniform pressure ythroughout the entire area of .the repair. ` ` » ' Other objects of the invention are: to provide a device of this character in which the hot plate will be inver-tedand ñxedly supported to prevent dirt, dust and other foreign materials from ac-v cumulating on -the surface; to provide a highly ef'rlcient mechanism for clamping the repair against the inverted hot plate; to provide means to ñrst rapidly close the repair against .the plate and then exert an extremely tight clamping con tact Ithereon; to provide means for accurately ad justing the clamping mechanism to accommodate repairs of various thicknesses; and' to provide means for vulcanizing the portions of tire‘tubes around the valve stems thereof. ‘ clamped to the bracket II by" means of Asuitable clamp bolts I4. A supporting arm I5‘is formed A heater housing I'I issecuredi-to the attach ment flanges I6 of the Aarms I5 by means of suit able bolts I8. The housing I1 is a box-like struc ture having a normally open bottom. The bottom is closed by means of a hot plate I 9 secured there in by means of counter-sunk screws 20. Suit able heating elements 2 I, of any of the standard: varieties, are secured to the upper surface‘of the. hot plate i9 within the housing I7. “ The tube .to be repaired is clamped against thel bottom surface of the hot plate I9, through the medìumïof a vertical sliding post 22, there being` one `of these posts s'lidably mounted in each of the sleeves I2. ` The upper extremity of each post 22 is ña't tened, as shown at 23, to pass between a pair of levers 24 formed on a bell‘crank lever fitting 25. The levers 24 are mounted on a pivot pin 30 ex Other objects and advantages reside in the tending through the flattened portion 23 of .the detail construction of the invention, which is de 25 post.` An operating handle 26 extends from they signed' for simplicity, economy, and eflìcieney. fitting 25. The fittings 25 are each supported on These will become more apparent from the fol-,-v lowing description. v ‘ In the following detailed description of the in vention, reference is had .to the .accompanying drawing which forms a part hereof. Like nu merals refer to like parts in all view of the draw lng. and throughout the description. In the drawing: Fig. 1 is a front view of .the improved tire tube plate; ‘ Y Fig. 2 is a side view thereof in .the _closed posi tion; ' Fig. 3 is a similar view in the open position, showing a portion thereof in section to illustrate the interior mechanism, `the section being Itaken 0n the line 6-3, Fig. 1: Fig. 4 is a‘fragmen-tary top view of a recipro cating post employed in the improved tube plate; y Fig. 5 is a detail cross-secticn,taken on the two connecting links 21, the lower extremities of‘ which are mounted on hinge bolts 28 on the op posite sides of the sleeve I2, and .the upper ex-> .tremities of which are mounted on hinge bolts 23l on opposite sides of the fitting 25. A bearing sleeve 46 carrying a swinging brack-A et 3| is rotatably mounted on the lower extrem ityjof each of the posts 22.
