Definitions

  • the present invention relates to socket wrenches and in particular to the sockets forming part of such socket wrenches.
  • a wrench in the form of a socketed head having a hollow end to fit over a multi-sided head of a nut or bolt, generally a hexagonally sided nut or bolt.
  • the socket may be permanently attached to an actuating handle in which case generally only one size or at most only two sizes of sockets may be provided, or there is provided a plurality of removable socket heads or as they are more generally called sockets.
  • the latter type of wrench namely one comprising a handle and a plurality of removable sockets is the more commonly provided type of socket wrench since the latter is more versatile allowing a plurality of sizes of nut or bolt to be handled by the one set of sockets.
  • a set of sockets is commonly used to include not just the socket heads or sockets per se, but also the combination of the socket heads and the actuating handle, which actuating handle in turn often comprises a rod having pivotally mounted on one end thereof a square sectioned male spud, each individual socket having on the end opposite to its hexagonally formed portion a square sectioned hole or more properly socket adapted to receive the socket.
  • a further minor problem is when one wishes to use more than one size of socket one is forced to carry on one's person possible sizes of sockets so that they may be available when required.
  • Patent Specification Nos. US 1471451 and US 5157995 each show a socket assembly comprising a tubular body with a set of nesting individual sockets retained on the body, each adjacent pair of nesting sockets comprising an inner socket and an outer socket, said inner socket being movable axially inwardly relative to the outer socket to expose said outer socket for use, the body having means for engagement with a lever for rotation of the sockets.
  • Patent Specification No. US 2322856 discloses a wrench having a socket at each end within which can be mounted one or more inserts to reduce the size of the socket.
  • the present invention is directed towards overcoming these and other problems.
  • a socket for a socket wrench of the type comprising an actuating handle carrying the socket, the socket comprising a tubular body with a set of nesting individual sockets on the body, each adjacent pair of nesting sockets comprising an inner socket and an outer socket, said inner socket being movable axially inwardly relative to the outer socket to expose said outer socket for use, the body having means for engagement with a lever for rotation of the sockets, characterised in that a set of nesting individual sockets is provided at each end of the body and an outer surface of the body at each end of the body is adapted for engagement by the lever for rotation of the sockets.
  • each nesting socket engages resiliently the other nesting socket or sockets, to require positive disengagement and reinforcement thus preventing the sockets from falling in and out of engagement by providing a force fit of an inner socket within the outer socket.
  • One way of achieving this is to provide on each socket a spring on the outer surface thereof to engage on the inner surface of the next outermost socket.
  • Various forms of springs may be provided such as are often seen conventionally in socket sets being resiliently mounted ball bearings or the like, indeed anything which provides a resistance against relative movement is sufficient.
  • the springs when used vary in strength decreasing from the outermost socket to the innermost socket of the set to ensure when the innermost socket is pushed inwards within the other socket, that the other socket it will not carry the outermost sockets with it.
  • each of the nesting sockets is biased outwardly, preferably by means of a spring.
  • each movable socket may be connected to a rear of the outermost socket by means of a helical spring thus providing in the central portion of the outer socket a nest of helical springs each of which biases a corresponding socket outwardly or alternatively they may be biased in a cascade effect.
  • restraining means in the form of a stop are provided to prevent a nesting socket fully withdrawing from its surrounding sockets. The advantage of this is that it is then impossible to lose the sockets of the set.
  • each socket is bevelled inwardly. Further, each successively smaller socket in a nest will be slightly recessed with respect to an adjacent larger socket.
  • the two separate sets of sockets are axially spaced apart within an elongate body member, said body member having a hollow central portion between end portions within which each set of sockets is mounted.
  • the spacing between the sets of sockets is chosen to accommodate only one set of sockets.
  • a further advantage in having sockets at both ends is that in addition to providing a versatile range of sockets it is also possible to provide for example metric and imperial sized sockets in the one set which is exceptionally advantageous. For example, having fourteen sockets from 6mm to 32mm means that while fitting fourteen sizes exactly you are only 1mm out on the intermediate sizes. The same will apply to imperial sizes.
  • each external surface surrounding the end portion is regular sided to form a male portion to engage a female socketed portion of a handle or an adaptor for mounting on the handle. This, it will be appreciated is advantageous, because it means that an easy connection between a handle and the body portion may be achieved.
  • the body portion itself has each end portion in the form of a socket thus utilising the body member itself as a socket.
  • the handle is a two-part handle comprising a rod having pivotally mounted on one end thereof a square sectioned male spud and a hollow adapter sleeve, one end of which is socketed to engage the external surface of a set of nesting sockets and the other end of which is socketed to receive the male spud.
  • One of the particular advantages of the present invention is that where a wide range of sizes of sockets are required, they can be relatively easily provided.
  • a socket for a socket wrench the socket being indicated generally by the reference numeral 1 comprising two sets of sockets indicated by the reference numeral 2, including a hollow adapter 3 and portion of an actuating handle 4.
  • the actuating handle 4 may house a ratchet mechanism as is common and is of generally conventional construction and the sockets according to the invention are for use with such handles which is obvious unless otherwise stated.
  • the two separate sets of sockets 2 are housed within a hollow body member 10 having two opposed end portions 11 on either side of a hollow central portion 12. Each end portion 11 itself forms a hollow socket and has a hexagonal outer surface 13. A plurality of individual nesting sockets 15, 16, 17, 18, 19 and 20 are provided in each end portion 11.
  • the individual socket 15 is the innermost socket and the individual socket 20 is the outermost socket. While the innermost socket 15 is an inner socket with respect to the next individual socket 16 in which it nests and the socket 16 therefore forms with respect to the innermost socket 15 an outer socket, the outer socket 16 in turn becomes an inner socket with respect of the next outer socket 17 which is therefore an outer socket with respect to the inner socket 16. It will be noted that only one set 2 of sockets is illustrated.
  • Each socket 15-20 carries a spring 21, not all of which are shown.
  • the spring 21 forms a force-fit between an inner and outer socket.
  • Each socket 15 to 20 inclusive nests inside its next outer socket, thus as stated above the socket 15 nests inside the socket 16, the socket 16 nests inside the socket 17, and so on.
  • Each socket is provided with a stop 22 which engages in a slot 23 in its next outer socket.
  • the stops 22 and slots 23 thus provide restraining means preventing full withdrawal in an axially outwards direction. Not all of these stops 22 or slots 23 are illustrated. It will be noted that each spring 21 engages a recess 24 in its next adjacent socket.
  • the adapter 3 comprises a hexagonally socketed hollow head 30 terminating in a square sectioned end hole 31 which is adapted to engage a square section spud 32 which is pivotally mounted by a pin 33 on the handle 4 only portion of which is shown. It will be appreciated in use that the adapter 3 and handle 4 may engage the hexagonal outer surface 13 to rotate the socket wrench 1 as illustrated in Fig. 6.
  • socket wrench 1 may then be used. This is particularly illustrated in Fig. 3. Referring now specifically to Fig. 3 there is illustrated the socket being offered up to three different sizes of bolt 35(a), 35(b) and 35(c) having different sizes of hexagonal head 36(a), 36(b) and 36(c) respectively. It will be seen how the different sizes of individual socket are required and may be used.
  • FIG. 7 there is illustrated an alternative construction of socket indicated generally by the reference numeral 40 having a hollow body member 41 having a cylindrical outer surface carrying a plurality of open slots 42 for engagement with axially arranged radial ribs 43 within an adaptor 44 which in turn has a square hole 45 for engagement with a spud 46 mounted on an actuating handle 4.
