Definitions

  • This invention relates to the assembly and disassembly of chains, particularly, though not exclusively, roller chains. More particularly, this invention relates to the extraction or insertion of a coupling, link pin or rivet used to secure together adjacent links of a chain.
  • chain links are typically constructed such that there is a clearance gap between the outer link plates and the inner link plates of the respective links at each joint.
  • One of the disadvantages of the aforementioned tool is that both during extraction and insertion of a rivet the inner and outer link plates at a joint are forced together as the rivet is forced through the respective link plates. Consequently, when adjacent links are disassembled or assembled using this tool the resulting joint is often too stiff to function properly, the outer link plates having been deformed inwards to lie against, and in some cases, to grip the inner link plates. This problem is currently alleviated by using the aforementioned tool in a different mode to deform the outer link plates to re-introduce a clearance gap.
  • Prior art tools have suffered from a disadvantage of initially deforming the links of a chain and of subsequently requiring a separate operation to reintroduce a clearance gap into a deformed link to permit the chain to function correctly.
  • a tool adapted to extract and/or insert a coupling from or into a joint connecting first and second chain components, the tool comprising drive means adapted to displace the coupling and the chain components relative to each other, and support means adapted to position the first and second chain components at an operative region of the tool such that when the coupling is being driven from, through, or into the joint each link plate at that joint is supported against plastic deformation.
  • the tool comprises a jaw in which a joint may be positioned and the drive means may move relative to the jaw to push a rivet into or from a joint held therein.
  • the drive means may comprise a punch mounted upon a carrier.
  • the carrier may be an externally screw-threaded shaft which is rotatable within a correspondingly threaded bore of the tool.
  • a trapizoidal type thread may be used for the drive means for the advantageous force transfer characteristics this provides as a power thread.
  • the tool may also be provided with position means adapted to position a joint of a chain in the tool such the the rivet or at least the bore of the joint through which the rivet passes is axially aligned with the axis along which the drive means is movable.
  • position means may comprise a saddle or equivalent roller locating means which may have an axially extending U-shaped recess adapted to receive a roller of a joint and hence to position the joint relative to the tool and to the drive means.
  • Orientation means may also be provided and may be adapted to permit a joint to be positioned in only one orientation at the operative region of the tool.
  • the orientation means may comprise a member, such as an orientation post, adapted to co-operate with the inner and/or outer link plates (for example adapted to be received between the outer link plates of a joint positioned in the tool).
  • the orientation means may be of such cross-section that it may be received between the outer link plates of the joint but cannot fit between the inner link plates of a joint. In this way a joint must always be positioned within the tool with its outer link plates co-operating with the orientation means.
  • the support means may comprise a rear anvil adapted to support directly the external surface of an outer link plate of a joint placed in the tool.
  • the support means may comprise a pair of rear anvils each rear anvil being separated by a slot, preferably an axially extending U-shaped slot.
  • each rear anvil is adapted to support the external surface of an adjacent outer link plate on an opposed side of the coupling receiving bore of the outer link plate.
  • the U-shaped slot may be adapted to receive a coupling which is pushed out cf the joint through the outer link plate. It will be appreciated that although only one support for the outer link plate may be necessary the provision of a pair of rear anvils to provide support on each side of the coupling receiving bore of the link plate provides greater support for the link plate against deformation.
  • the outer link plates are convex in shape rather than planar.
  • one or each of the rear anvils may be provided with a rear anvil recess which extends axially towards the anvil to provide an axial anvil projection adapted to provide the point of contact between that anvil and the adjacent link plate.
  • the support means may be adapted to directly support each link plate of a joint. Alternatively or additionally, the support means may position the chain components such that each link plate is supported. One link plate may support another via their contact.
  • the aim of one embodiment of this invention is to prevent plastic deformation of the link plates of a joint when a rivet is forced into, through, or out of a joint. Consequently, it is not necessary that each link plate be supported to prevent any possible axial movement but merely that each link plate be sufficiently supported so that no permanent plastic deformation occurs during the rivet inserting or extracting process. Elastic deformation may be permissible. Similarly, the link plates need not be supported when at rest but need only to supported when a coupling is being driven into, from, or through a joint.
  • orientation means may also provide a support member forming part of the support means and being adapted to support directly the inner surface of the outer link plate opposite the drive means.
  • the support means is adapted to directly support the outer surface of an outer link plate positioned opposite the drive means and to position the first and second chain components at a relative angle so that the outer surface of each inner link plate contacts the inner surface of its adjacent outer link plate. Additional support means may be provided to support directly any of the link plates.
  • the inner link plates at a joint are held in spaced apart relations.
  • the inner link plates at a joint are kept apart by bushes upon which the roller rotates. Consequently, where a tool is adapted for use with roller chains it is not always necessary to provide support means to support the inner link plates at a joint.
  • the rear outer link plate may be supported against axial movement of the rivet by the rear anvil and the front outer link plate may be supported by its adjacent inner link plate.
  • the first and second components may be positioned at a relative angle by an angling formation.
  • the angling formation may project axially from the rear anvil and be adapted to deflect an inner link plate of a joint relative to the anvil and consequently to introduce an angle between the first and second chain components.
  • a tool adapted to extract or insert a coupling from or into a joint connecting first and second chain components, the tool comprising drive means adapted to displace the coupling and the chain components relative to each other and angling means adapted to position the first and second chain components at an angle relative to each other at an operative region of the tool when the tool is in use.
  • the relative angle between the first and second chain components may be induced when the joint of a chain is introduced into the tool or the angle may only be induced by engaging the drive means with the rivet of the joint.
  • the support means preferably induce a sufficient relative angle between the inner and outer link plates such that there is a point of contact providing a point of support between each inner link plate and its adjacent outer link plate at a joint.
  • a tool adapted to insert or extract a coupling into or from a joint connecting first and second chain components, the tool comprising drive means adapted to displace the coupling and the chain components relative to each other, support means adapted to support the components against the axial displacement of the coupling and orientation means adapted to allow the first and second components to be positioned in only one orientation relative to the support means at an operative region of the tool.
  • a tool adapted to insert or extract a coupling into or from a joint connecting first and second chain components, the tool comprising drive means adapted to axially displace the coupling and the chain components relative to each other, support means adapted to support the components against axial displacement of the coupling and the tool having only one site at which the joint may be positioned within the tool.
  • the tool comprises a jaw within which the joint of a chain is positioned and the width of the jaw is such that the joint may only be introduced into the jaw at one site.
  • a tool adapted to insert or extract a coupling into or from a joint connecting first and second chain components, the tool having an operative region at which are provided drive means adapted to displace the coupling and the chain components relative to each other, support means adapted to support the components during use of the tool, and retention means adapted to prevent the chain components from accidentally leaving the operative region.
  • the retention means is preferably movable relative to the operative region.
  • the retention means may comprise a member mounted on the body of the tool, and adapted to be held manually against the chain components positioned in the tool. Preferably the retention means applies pressure in use to the chain components. The retention means may also assist in correctly aligning a joint within the tool.
  • a tool adapted to extract or insert a coupling from or into a joint of a chain, the tool comprising a handle adapted to be held in the hand of an operator when the tool is in use.
  • the handle may also be adapted to be held in a vice or clamp when the tool is in use.
  • a tool adapted to extract or insert a coupling from or into a joint connecting first or second chain components the tool comprising storage means adapted to store a coupling which may be inserted in to the chain.
  • the storage means may comprise a hole provided in the body of the tool into which a coupling can be inserted.
  • the hole may be closed by a removable cap to prevent a stored coupling from falling out accidentally.
  • Couplings for use with a coupling inserting tool are easily lost or misplaced and it is convenient to provide storage mean associated with the tool.
  • a tool adapted to extract or insert a coupling from or into a joint connecting first and second chain components, the tool comprising drive means adapted to axially displace the coupling and the chain components relative to each other, support means adapted to support the chain components against axial displacement of the coupling, and indicating means adapted to indicate a position of the drive means relative to the tool.
  • the indicating means provide a visual marker which indicates the position of the tip of the punch relative to the tool.
  • the pin When extracting a coupling (or pin) from a joint it is preferable that the pin is not pushed entirely through and out of the joint but is retained with one of its ends held in the rear outer link plate. In this way the chain components can be separated and when an operator attempts to join the outer link plates to the inner link plates of another joint he or she can use the rivet which is still held in the outer link plate and which is already correctly aligned with the bore through which the rivet is to pass.
  • the indicating means comprises a first visual marker provided on and moving with the drive means and a second stationary visual marker provided on the tool body. Alignment of the first and second markers may indicate that the punch has been advanced to a sufficient position to permit the release of the joint whilst retaining the rivet in the outer link plate.
  • a tool adapted to extract and/or insert a coupling from or into a joint connecting first and second chain components
  • the tool comprising drive means adapted to displace the coupling and the chain components relative to each other, support means adapted to support the chain components against displacement of the coupling and stop means, associated with the drive means, adapted to limit the distance by which the drive means may be advanced with respect to the support means.
  • the stop means are adapted to prevent a user advancing the punch too far when pushing a coupling out of a chain joint and accidentally pushing the coupling entirely out of the join as opposed to leaving one end of the coupling retained in the rear outer link plate.
  • the drive means comprises a punch mounted on a screw threaded carrier
  • the stop means may be provided by a stop member which cooperates with the screw threaded carrier to prevent the carrier advancing beyond the stop member.
  • the stop means may be formed as an integral part of the housing in which the screw threaded carrier is rotated to advance the punch.
  • a method of extracting or inserting a coupling from or into a joint connecting first and second chain components comprising supporting each of the first and second chain components against plastic deformation and displacing the coupling axially relative to the components to extract it from or insert it into the joint.
  • a method of extracting or inserting a coupling from or into a joint connecting first and second chain components comprising inducing a relative angle between the first and second components and displacing the coupling axially relative to the components to extract it from or insert it into the joint.
  • FIGS 1a, 1b, and 1c illustrate lengths of roller chain 2 comprising first and second chain components 4, 6, each chain components comprising a pair of opposed link plates 8. Adjacent first and second chain components are connected by a coupling in the form of a pin or rivet 16 passing through a joint 10, of the chain.
  • Four link plates 8 are coupled together by the rivet 16 at the joint 10 the inner two link plates being separated by a bush 12 over which is located a freely rotatable roller 14.
  • the joint 10 is provided with a clearance gap (not shown) between the inner and outer link plates to allow the first and second chain components 4, 6 to rotate freely about the axis of their linking rivet 16.
  • a tool 20 for inserting or extracting a coupling comprising a rivet 16 into or from a joint 10 of a chain 2 has a body 22 comprising a handle 24 and an operative region in the form of a jaw 26 adapted to receive a joint 10 of a chain 2 from or into which a rivet 16 is to be extracted or inserted.
  • the handle 24 is provided with a palm engaging side 28 and finger grip formations 30 on an opposed side; it is adapted to be gripped in the hand of an operator the finger grip formations 30 facilitating the holding of the tool in the hand.
  • the handle 24 may be secured in the jaws of a vice or clamp.
  • the tool 20 also has drive means positioned at the front of the tool and comprising a punch 34 mounted upon a carrier comprising an externally screw-threaded shaft 36 which is rotatable within a correspondingly threaded bore 38 provided in the body 22 of the tool 20.
  • the punch 34 is adapted to connect with a rivet 16 of a joint 10 positioned in the jaw 26 of the tool and to drive the rivet through the joint.
  • the punch 34 is advanced or retracted relative to the jaw by rotating the screw threaded shaft 36 which is provided with a drive hand 40.
  • the drive handle 40 facilitates manual rotation of the drive means and also provides a mechanical advantage to increase the force provided by the operator which is transmitted to the punch 34 by the drive means to displace the rivet 16 of a joint 10.
  • the tool also has support means comprising a pair of rear anvils 44, 46 (shown in figures 4 and 5) separated by a U-shaped slot 48.
  • Each rear anvil 44, 46 is adapted to directly support the external surface of an adjacent outer link plate of a joint 10 positioned in the jaw 26 of the tool 20.
  • the rear anvils 44, 46 support this outer link plate on either side of the bore of the link plate in which the rivet 16 is received when the joint 10 is assembled.
  • the rivet 16 when a rivet 16 is pushed through a joint to release the first chain component 4 from the second chain component 6, the rivet 16 is not pushed entirely through the joint but is pushed sufficiently to release the first and second components but with one of its ends still retained within the rear outer link plate; this is described below in more detail and facilitates the reinsertion of a rivet 16 into a joint 10.
  • the rivet 16 When the rivet 16 is held in this way with one of its ends held in the bore of the rear anvil link plate, the free end of the rivet projects into the U-shaped slot 48 between the pair of rear anvils 44, 46.
  • the rear anvil 44 which is adapted to lie opposite the outer link plate at a joint is provided with a rear anvil recess 50 and a rear anvil projection 52, as illustrated in Figures 6 and 7.
  • one rear anvil 46 supports the end of the rear outer link plate 81 of a joint positioned in the tool and the rear anvil projection 52 of the other rear anvil 44 supports a portion of that rear link plate on an opposed side of the bore through which the rivet 16 passes.
  • any convex curve of an outer link plate (not shown) is accommodated by the rear anvil recess 50 so that the longitudinal axis (referenced 100) of the second chain component 6 lies parallel to the ends of the U-shaped slot 48 emerging into the jaw 26 of the tool 20 and the free end of that outer plate is not pivoted away from its respective rear anvil 46 by a convex outer link plate having two points of contact with the other rear anvil 44.
  • the support means also comprise an angling formation in the form of an angling post 54.
  • the angling post 54 contacts the rear inner link plate 83 of a joint 10 positioned in the tool and positions the first chain component 4 at a respective angle to the second chain component 6 so that its longitudinal axis (referenced 101) is not parallel to the longitudinal axis 100 of chain component 6.
  • the inner link plates 83, 84 at a joint are not planar but are partially concave about their respective longitudinal axis (for example Seddis (TM) chains) .
  • the angling post 54 comprises a post of radial cross section which projects axially from the rear anvil 46 and is adapted to be opposite the rear inner link plate 83 of a joint 10 positioned in the jaw 26 of the tool.

  • the inter-plate post 56 is adapted to be received between the opposed outer link plates 81, 82 of a joint 10 positioned in the tool and to provide an additional support for the front outer link plate 82 against plastic deformation when the tool is in use.
  • the inter-plate post 56 also provides orientation means which permit a joint 10 to be positioned in only one orientation within the tool.
  • the width of the inter-plate post is less than the distance separating the opposed outer link plates 81, 82 at a joint 10 but is greater than the distance separating the opposed inner link plates 83, 84 at a joint.
  • the inter-plate post can therefore only be received between the opposed outer link plates of a joint 10 positioned in the tool and consequently the joint 10 can only be positioned in the jaw 26 of the tool in this orientation (in fact it will be appreciated that the chain an also be put in upside down, but that the first and second components will have the same effective configuration).
  • the support means positions the first and second components 4 , 6 of a chain at a relative angle within the jaw 26 of the tool (as shown in figure 7).

  • the inner link plates 83, 84 are held apart by an internal pair of bushes 12 and each link plate of the joint 10 is thus supported against plastic deformation; the rear outer link plate 81 is supported by the rear anvils 44, 46; the inner link plates 83, 84 are supported by the pair of bushes 12 and the front outer link plate 82 is supported firstly by its contact with the front inner link plate 84 which is in turn supported through the pair of bushes by the rear inner link plate 83 acting against the rear outer link plate 81 and the angling post 54, and additionally by the inter-plate post 56.
  • the tool 20 is also provided with position means comprising a saddle 58 arranged to facilitate positioning of the joint having the rivet 16 (or that is to receive the rivet 16 when a rivet is being reintroduced to join the two chain components) so that the rivet is aligned with the punch 34 and with the U-shaped slot 48 provided between the pair of rear anvils 44, 46.

  • the distance between the inter-plate post 56 and the front and rear of the jaw 26 is not sufficiently large to allow a first or second chain component 4, 6 to be inserted between the inter-plate post 56 and the front or rear surface of the jaw 26. Consequently, a joint 10 can only be positioned in the jaw 26 with the opposed outer link plates 81, 82 of a joint 26 surrounding the inter-plate post 56. There is thus only one site within the jaw at which a joint 10 can be positioned and this reduces the risk of an operator mis-positioning a joint 10 within the jaw 26.
  • the front surface of the jaw 26 is provided with a central insert rivet slot 42.

  • the retention means in this embodiment also assists in ensuring that the chain is in a proper position before the drive means is operated, and in ensuring that there is only one way in which the chain can be positioned.
  • a part circular profile 91 of the pressure plate acts against the top of the roller 14 of a joint positioned in the tool. This biases the roller 14 (and consequently the rivet passing through the roller) into alignment with the line of the punch 34 so that the joint is encouraged into the correct position for correct operation of the tool.
  • the roller 14 is thus held to one side by contact with the part circular profile 91 of the pressure plate and on the other side by contact with the inter-plate post 56.
  • the retention means, in association with the profile of the jaw 26, also helps to prevent the chain components accidentally slipping out of the operative region 26 of the tool; a flat profile 92 of the retention means acts against the top of the link plates positioned in the tool to assist in this.
  • Storage means comprising a storage hole 68 is provided in the body 22 of the tool 20.
