Abstract
Abstract of the Disclosure An apparatus for removing the rubber tire casing from the steel rim of an automobile wheel which comprises a set of hydraulic cylinders and wedge-shaped members which simultaneously converge on the tire casing and wheel to deform the tire rim into the figure of a three-leaf clover so that the tire rim can easily be removed from the inside of the casing. The wedge-shaped member includes means for gripping a tire.
Description
1077~86 Background of the Invention Field of the Invention. This invention relates generally to scrap recycling means and more'specifically, to a portable scrap recycling device for quickly and efficiently removing the steel rim from the tire casing.
Description of the Prior Art. The use of recycled auto-mobile bodies and particularly automobile wheeIs has been practiced --for some time. Each year there are twenty to thirty million wheels that are relegated to the junk yard because the automobiles are no longer drivable or operable.' In the past, the practice was to remove those whiGh are good and seIl them as used tires and those tires which were of no value were removed from the rims by burn-ing. However~ burning of rubber tire casings is an atrocious pollution producing process.
An aLternative way to recycle the steeI rim is to remove the tire from the rim by the'conventional auto removal tools which usually is a time-consuming and costly process. This is undesir-able because~ in most instances, the tire is of little or no value.
Typical of some'of the prior art devices employing three 20 members are exemplified by the'United States Fair patent 2 r 857,824;
the United States Hall patent 2,918,699; the United States Barnes ' patent 3,020,831; the United States' Neilsen patent 3,039,518 and the United States Davidson et al patent 2,730,166. Briefly, the patent to Fair shows a machine fox forming soil pipe around a mandreI. The Hall patent shows the'high pressure press with arms that converge. The Barnes patent shows an apparatus for applying ~' circumferential pressure on a tire'or the like. The Neilsen patent shows a tubeless tire bead seating apparatus. The Davidson patent shows a mobile trolley mounted tire removing machine in which man-drels break the bead away from the rim of the automobile.
All of these patents are'typical of prior art patents -using three or more devices in some'operation. However, all of these types of prior art devices are for a manufacturing or re-pairing process. The purpose of the present invention is for separation of a tire casing from a wheel through destruction of the casing. The present invention comprises a solution to the problem of removing the tire casing from an automobile wheel rim through a process of compressing and deforming the wheel rim so that it will drop out of the tire casing.
Summary of the Invention Briefly, the present invention comprises apparatus for crushing a vehicle wheel rim with the tire thereon, comprising a pusher head for applying radial pressure upon each of at least three substantially equally circumferentially spaced locations against the tire to move the latter inwardly against the rim and collapse the rim, hydraulic means for moving each said pusher head and comprising a power cylinder with a plunger operatively connected to each corresponding pusher head, means mounting each said cylinder upon a radially extending beam with the several beams rigidly secured centrally of the apparatus to constitute a frame therefor, and slide means supporting each pusher head upon the corresponding beam and interlocking the same against any tendency for said pusher head to raise from the beam.
According to another aspect of the invention, there is provided the method of crushing a vehicle wheel rim with a tire thereon comprising applying radial pressure upon at least three substantially e~ually circumferentially spaced locations against the tire to move the latter inwardly against the rim and collapse the rim, thereupon releasing the pressure and re-moving the tire from the collapsed rim.
Brief Description of the Drawing Fig. 1 is a top view of a portable automobile tire rim crusher; and - Fig. 2 is a detailed~ iew of the member for holding the ' :- ' tire during the crushing process.
Description of the Preferred Embodiment Referring to the drawing, reference numeral 10 generally designates our portable automobile tire rim crusher. The auto-mobile tire rim crusher is a trailer that comprises a main frame 11 having a wheel 12 on one side and a wheel 13 on the opposite side. A ball hitch 9 is connected to main frame 11 through arms 30, 31 and 29. Located on the rear portion of automobile tire rim crusher is a compartment 14 which contains an engine and hydraulic pump (not shown). Typically, the engine may be a gas engine with a hydraulic pump connected thereto. Located adjacent the engine pump housing 14 is an oil reservoir 15 for containing the oil used in the hydraulic rams. Both of these items are standard and well known and will not be described or shown here-in.
Emanating from the engine and pump housing 14 are sets - 2a -:
~ 077686 of hydraulic hoses which go to the three hydraulic cylinders 20, 21 and 22. As all three of the hydraulic cylinders are identical, only hydraulic cylinder 20 will be described herein.
A pair of hydraulic lines 23 and 24 supply hydraulic fluid under pressure to hydraulic cylinder 20 which is mounted firmly to the main frame 11 of trailer 10. An extendable arm 25 slides within the hydraulic cylinder 20. Located on the end of extendable arm 25 is a head 26 that slides along member 29, a face 27 and a wedge-shaped elongated member 28. Wedge-shaped member 28, while only shown in a top view, is of sufficient width so as to have a width greater than the width of the tire 50 and rim 51.
As shown in the drawing, the tire 50 and rim 51 are placed in a central position between hydraulic cylinders 20, 21 and 22 which are located at 120 angles around tire 50 and rim 51.
In operation ofour portable tire rim crusher, the opera-tor begins by starting the engine located in engine housing 14.
Next, a tire and rim are placed between the three hydraulic cylin-ders. The operatox then activates the hydraulic pump located there-in. The hydraulic pump simultaneously supplies hydraulic fluidto hydraulic cylinders 21, 22 and 20, thus forcing the wedge-shaped members 28, 35 and 36 radially inward toward tire casing 50 and tire rim 51. The hydraulic cylinders continue to converge until members 35, 36 and 28 have physically deformed tire rim 51 into a cloverleaf shape.
Next, the operator releases the hydraulic pressure on the hydraulic cylinders and retracts members 28, 36 and 35. This allows the resilient tire casing to SNap back if it has not been cut off by the wedge members. When the tire casing snaps back, it will be found that the tire rim 51 has been crushed into a three-leaf clover shape which has an outside diameter which is smaller than the inside diameter of the tire casing so that the tire casing ~77686 can be quickly and easily removed from the tire rim.
~ eferring to Fig. 2, reference numeral 26 designates the head which slides along member 29. Attached to head 26 is a wedge-shaped member comprised of blade 63, side 60 and back support 64. Located on the edge of blade 63 is a set of serra-tions comprising flat portions 61 and curved portion 62. It has been discovered that the serrated surface prevents slipping be-tween the tire and the wedge-shaped member even when the tire is wet. Thus, an operator can crush the rim under both dry and wet conditions.
From the above description of the present invention, it is apparent that the present invention almost instantaneously de-forms the'tire rim so that the'tire casing can be lifted there-from and thus allow the tire rim to be recycled as scrap metal.
Another feature of the invention is that the present invention is portable and thus can be'towed from junk yard to junk yard. This feature, while'unimportant to large junk yards is sig-nificant in rural areas where the'ownership of equipment of this nature is generally too expensive ~or the'small junk yard opera-tion; however, a small junk yard operator can store his wheelsand tires until it is practical to rent or hire someone to remove the tire casings from the wheels.
