Abstract

A Tyre Remover to complete the first operation of tyre removal consists of an angle iron frame 15 to clamp onto a wheel and tyre and a mechanical device associated with the frame 15 to break the seal between the tyre and the wheel. The frame 15 can be dismantled and transported in the boot of a car or van, assembled and used on site. Its universal design enables it to be used an all tyre sizes and can be used quite safely by following simple instructions. <IMAGE>

Description

SPECIFICATION Primarytyre remover This invention relates to a Primary Tyre Remover.

This tool is designed for use in Service Garages or by D.I.Y. motor car enthusiasts to enable a motor vehicle tyreto be removed and repaired more easily.

The main problem with tubed ortubeless tyres is thatafterthey have been in ruse a long time the tyre becomes stuck on the wheel rim, thus making it impossibleto get a tyre repairleverunderthetyre.

The existing equipment as used in tyre repair garages is expensive to buy, being mostly compressed-air-operated, and is not mobile.

Thetool comprisesa two componentwelded angle iron frame 15 Figure 5which fits under and abovethe wheel. The top main angle component is made up of two pieces of angle iron mounted back to back with three flat distance plates 1 5a welded in between 15 Figure 2. On one end of 15 is mounted a guided steel wedge 12 Figure 4which is driven downwards by means of a large threaded set screw and is also able to swivel on two fulcrum pins 9 Figure 4. At the other end of 15 is fitted an adjustable steel locating lug 8 Figure 3 which can be locked into position by a set screw.The other component 15b Figure 5 is just a straight piece of angle iron suitablydrilledto mate up with the main angle component 15. Thejig is held together by two threaded rods 14 FigureS which pass throughthetopand bottomframes and when positioned correctly can be tightened down so asto pull 15 and 15btogetheron eitherside ofthewheel.

The operation ofthe invention will now be described by way of example with reference to the accompanying drawings in which:- Figure 1 shows details ofthe wedge and guide.

Figure2 illustrates the Plan View of the jig in position on the wheel.

Figure3showsthe position ofthe locating lug prior to operation.

Figure 4shows details of the wedge priorto operation.

FigureS illustrates the side view ofthe jig in position on the wheel.

Referring to the drawing the clamp 15 and 1 sub Figure 5 is fitted on either side of the wheel as shown in Figures 2 and 5 and located top and bottom by the locating lug and wedge as shown in Figures 3 and 4.

The jig can now be tightened down using thetwo screwed rods 14 FigureS. When pressure is applied onto the set screw 13 Figure 4, the wedge, 12 Figure4 is forced down between the tyre 11 and wheel rim 10 (this may have to be done in two stages after re-positioning the locating lug and the inclination of the wedge) thereby pushing the tyre into the wheel well. The operation is repeated on the other side. The tyre can now be removed using tyre levers in the normal manner.

1. A Primary Tyre Remover comprising a welded angle iron frame with means to clamp on to a tyre and wheel and by a mechanical device push the tyre into the well, thereby breaking the seal and therefore enabling a tyre lever to be inserted under the tyre rim for the tyre to be removed. This operation can be carried out on site.

2. A Primary Tyre Remover as claimed in Claim 1 wherein means are provided for itto be easily dismantled and carried in the bootofa carorvan.

3. A Primary Tyre Remover as claimed in Claim 1 and Claim 2wherein means are provided to make it suitable for all sizes of tyre.

4. A Primary Tyre Removerthat can be easily operated by following simple instructions.
