EDITORIAL NOTE 2008200851 Description contains six pages 1 Australia (Patents Act 1990) Application Specification Press Master (Trade mark applied for) File No: 0984992851 A new design in mechanical pressing and pulling. The invention is described in the following statement 5 Press Master (Trade mark applied for) File No: 0984992851 Automotive Bush, pulley, sleave, Rose Joint, ball end joint remover replacer As well as a compact tool for the parting, stretching, pressing together or pulling apart using a screw type mechanical force all in one tool. 1. Ever since the beginning of the engineering age there has been a restraint of space and of the required equipment for removing bushes, pulleys and joint connectors from links and arms, especially while they are still located in their working positions by a way or means other than big , bulky and awaked presses or other hydraulic or mechanical equipment. 2. This is in particular a problem in the automotive industry with a magnitude of bushes joints, hubs and pulleys of a wide variety of sizes in a wide variety of places. This has become even more of a problem over the last couple of decades with design advances in bushing techniques, designs, and also in the style of equipment installed on the automobile. The compact and modular design of vehicles means that it requires major disassembly of sections to enable access to these components for service replacement. This means that a simple bush or pulley replacement can be a very time consuming and costly job. 3. The Press Master is different as it is very compact. It will fit in to most small and hard to operate areas to provide a press that can remove and refit bushes, pulleys and joint fittings with the minium of disassembly or even still, enable the component to be changed when the design prohibits the use of bigger and bulkier hydraulic or mechanical apparatuses. 4. The Press Master also takes away the problem of striping threads when using the "threaded rod and nuts" technique in trying to perform these jobs as the bolt or rod is only used to hold the components together and the work load is carried out by the Press master. 6. The Press Master is made up of an internally threaded main outer body (A) which can be made out of steel, alloy steel, alloy, poly product, or any appropriate commercial material deemed suitable, This outer body is hollow through and in the seating end (Al) incorporates a thrust bearing of the appropriate strength to enable the load to be transferred smoothly to the thrusting surface. Opposite the thrust bearing end (A2) there is a section machined to enable the use of a spanner, suitable tools or holding equipment to turn or hold the said outer body (A) when required to do the pressing or pulling action. The main outer body can be held in a clamp or by an appropriate means to secure it to the press thrust surface. The outer body has provisions for clamping incorporated in the outer section via a recessed groove.
6 7. The Press Master has an externally threaded main inner body (B) which can be made out of steel, alloy steel, alloy, poly product, or any appropriate commercial material deemed suitable. This inner body is hollow through and has a seating end (B 1) incorporates a thrust surface that enables it to push against an inner pilot thrust pin (C) when it is screwed and at the opposite end (B2) has a suitable surface machining to enable the use of a spanner, suitable tools or holding equipment to apply force when it is wound into or out of the internally threaded main outer body(A), or held to enable the outer main body (A) to be wound, forcing the pilot pin through the bottom section of the thrust bearing end to apply pressure to the component requiring pressing. 8. The externally threaded main inner body (B), incorporates a section in the spanner end (B2) which enables a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener to secure against a ledge, flange, ridge, flat or curved surface, enabling that when the inner and the outer main body, with or without the pilot thrust pin component (C) being fixed between the outer main body (A) and the inner main body (B) and the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener being retained or restrained at some given point through or against a bush, pulley, shaft, or holding component a pulling or pressing action is achieved. 9. The pilot thrust pin (C) has a curved or flat surface to which the thrust end of the inner main body (B) thrust end (B 1) forces against when it is wound into the main body (A) to push the pilot thrust pin (C) through the thrust bearing end (Al) of the main outer body (A). The pilot thrust pin (C) is made of suitable material of suitable strength and is hollow to enable a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener and the pulling adaptor to pass through it. Not with standing it can also be of a solid material when needed for pressing in different and difficult situations. The pilot thrust pin may incorporate a friction or thrust washer between it and the said part (B) to enable easier application of force. 10. The passing through the Press Master of the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener to a component to be pressed or pulled enables the operator to screw or adjust the tension onto the component to be removed or to be fitted by the means of turning the threaded main body (B) into or out of the main body (A) while it is forcing a thrust pressure against a suitable adaptor suitable for sustaining the force required to release or install the said component to the required position. 11. The Uniqueness of the Press Master is that it provides six ways or component pressing and six ways of component pulling.
7 12. The six ways of pulling are: I/ Achieved through holding the main outer body (A) to the component to be removed and using spanners, suitable tools or holding equipment to apply force when it is wound, tightening up the main inner body (B) forcing the pilot pin (C) through the main body (A) to force against the components locating shaft, to release the grip of the component, to release it from the said shaft. II/ Locate a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener through the main inner body to a suitable receiving adaptor then the component and to another suitable pulling adaptor or restraint and be secured. Then by holding the main outer body (A) and screwing the main inner body (B) using spanners suitable tool or equipment to apply force forcing the pilot thrust pin (C) against the said receiving adaptor which in turn pulls the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener and the pulling adaptor and component from its secured position. III/ Disassemble the main body (A) from the main body (B) and remove the pilot pin (C), refit the main body (B) back into the main body (A) then by locating a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener through the main inner body to a suitable receiving adaptor then the component and to another suitable pulling adaptor or restraint and be secured. Then by holding the main inner body (B) using spanners, suitable tools or holding equipment to apply force and screwing the main outer body (A) using spanners, suitable tools or holding equipment to apply force, forcing the thrust bearing surface against the said receiving adaptor which in turn pulls the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener and the pulling adaptor and component from its secured position. IV/ With part (A) and part (B) fully screwed apart fit the Press Master in between the components to be pulled together, attach a rod or similar through part (B) and secure at (B 1) with a nut or similar securing method. At part (A) attach a rod or similar through (Al) and secure by nut or similar, to part (B) and attach the extended ends to what you are wishing to be pulled, screw (A) and (B) together and pull the attached components together. V/ Attach suitable bracket and legs to the outer body (A) and locate the legs under the component to be removed, adjust the legs so that when (A) and (B) are screwed together the thrust bearing is against the pressing surface or fit a shaft of suitable length between the thrust bearing and the press surface, then hold the (B2) section and tighten (A2) to force the legs to remove the component. VI/ Attach suitable bracket and legs to the outer body (A) and locate the legs under the component to be removed, adjust the legs so that when (A) and (B) are screwed apart the pilot thrust pin (C) is against the pressing surface or fit a shaft of suitable length between the pilot thrust pin (C) and the press surface, then hold the (A2) section and tighten (B2) to force the legs to remove the component.
8 13. The six functions of pressing are: I/ Achieved through holding the main outer body (A) to the component to be installed and using spanners, suitable tools or holding equipment to apply force when it is wound, tightening up the main inner body (B) forcing the pilot pin (C) through the main body (A) to force against the component, to push or press the component, onto its accepting shaft or into its orifice. II/ Locate a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener through the main inner body to a suitable pressing adaptor then the component and to another suitable pulling adaptor or restraint and be secured. Then by holding the main outer body (A) and screwing the main inner body (B) using spanners, suitable tools or holding equipment to apply force forcing the pilot thrust pin (C) against the said pressing adaptor which in turn pulls the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener into the receiving adaptor forcing the component into its secured position and location. III/ Disassemble the main body (A) from the main body (B) and remove the pilot pin (C), refit the main body (B) back into the main body (A) then by locating the main outer body (A) to a suitable receiving adaptor then the component and to another suitable pressing adaptor or restraint and be secured with a rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener. Then by holding the main outer body (A) using spanners, suitable tools or holding equipment to apply force and screwing the main inner body (B) using spanners, suitable tools or holding equipment to apply force, forcing the main inner body (B) away from said receiving adaptor which in turn pulls the rod, bolt, threaded rod, shaft, pin, connector, retainer, or other suitable fastener and the pressing the component into its secured position. IV/ With part (A) and part (B) fully screwed together fit the Press Master in between the components to be pulled together, attach a rod or similar into part (B) and secure at (B2) to the recess or ledge .
