Definitions

  • This invention relates to a delivery device for delivering a liquid from a container to a dispenser, particularly for delivering beer from a keg, and to a safety device therefor.
  • the keg is provided with a spear valve which includes a beer assembly valve located in the keg neck and a stainless steel down tube which projects into the beer in the keg.
  • the spear valve normally closes the keg and, when the keg on site for dispensing, a tapping head is connected, in known manner, which applies a CO2 overpressure and allows beer to be supplied under pressure to the dispense tap at the point of sale.
  • An object of the present invention is to provide an improved safety device for a delivery device such as a spear valve.
  • a safety device suitable for fitting to a keg spear valve, comprising at least one locking member which, when fitted, is movable relative to the spear valve whereby the keg spear valve may be inserted into a keg neck without disassembly, the or each locking member, during insertion, moving outwardly relative to the spear valve, once through the keg neck, so that the or each locking member will prevent the spear valve from being ejected from the beer keg by residual pressure by engagement behind the keg neck.
  • the or each locking member pivots on the spear valve and is biassed outwardly relative to the spear valve so that, on insertion, the or each locking member moves inwardly relative to the spear valve so as to pass through the keg neck before moving to the outer locking position.
  • the safety device is for a keg spear valve including a valve body having a down tube with a bell-shaped outer portion, a beer valve and a valve sealing member, the or each locking member being fitted inside the bell-shaped outer portion and including a locking ear which is biassed by the valve sealing member to project through an opening in the bell-shaped outer portion.
  • the safety device includes a body having at least two locking members loosely pivoted thereon such that, on attachment to the spear valve and insertion into a keg neck, they move by gravity into a position in which they will engage behind the keg neck.
  • the locking member or members may be spring-biassed into an outer position. The locking members may be pivoted for movement in the direction of insertion or pivoted for movement laterally.
  • a spear valve assembly for insertion into the neck of a beer keg including at least one movable locking member which, after insertion of the spear valve into the keg neck, moves outwardly relative to the spear valve so that the locking member or members prevent the spear valve from being blown out of the keg by engagement behind the keg neck.
  • the spear valve assembly includes a spear valve assembly including a valve body having a down tube with a bell-shaped outer portion, a beer valve and a valve sealing member, the or each locking member being fitted inside the bell-shaped outer portion and including a locking ear which is biassed by the valve sealing member to project through an opening in the bell-shaped outer portion.
  • the spear valve assembly includes a spear valve assembly comprising a valve sleeve for engagement with a keg neck and a valve body releasably engaged with the valve sleeve and including a down tube for projecting into beer in a keg, a valve co-operable with the valve sleeve to close the keg, and spring means acting between a reaction member on the down tube and the valve biassing the valve into its closed position, a locking member pivoted to the valve body and being biassed into its outer locking position by the spring means and acting against the reaction member.
  • the spear valve may include a valve sleeve and integral valve body with down tube or a separate valve sleeve and valve body.
  • the beer valve sleeve and valve body may be engaged together by means of a bayonet connection with protrusions on the valve body engaging within T-shaped recesses on the valve sleeve.
  • the recesses be provided with a locking position into which the respective protrusion may be located and that the valve sleeve and valve body then be retained in that position by means of a rubber seal whereby the valve sleeve and valve body may not be separated without removal or destruction of the rubber seal.
  • the invention also includes a method of converting a keg spear into a safety keg spear to prevent the spear being ejected on unintentional pressurized release, the spear including a valve sleeve for engagement with the keg neck, a valve body having a down tube for projecting into beer in a keg and a valve for controlling fluid flow through the spear, and a skirt on one of the valve sleeve or the valve body including openings for the throughflow of beer during filling, the method comprising: forming a further opening in the skirt, locating a safety device having a projecting portion within the skirt and biassing the safety device outwardly so that the projecting portion projects through the said further opening after insertion through the keg neck so as to engage behind the neck on unintentional pressurized release.
  • Figure 1 shows a spear valve assembly (1) including a locking ring (2), a valve sleeve (3) and a valve body (4).
  • the valve body (4) includes a projection (5) and engages with recesses (6) in the valve sleeve (3) by a bayonet connection.
  • a beer valve (7) including an annular rubber sealing member (8) is located within the valve body (4) and the body further includes a depending down tube (9).
  • the down tube (9) has an annular shoulder (10) forming a seating for a spring (11) which biasses the beer valve (7) to a closed position.
  • An O-ring seal (12) for sealing against the keg neck is also shown.
  • the operation of this equipment is very well known and will not be described in detail. The principle is that when top pressure is applied to beer in the keg and when the valve (7) is open, ie. lowered against the action of the spring (10), the beer will flow up the down tube (9) and through openings in the valve (7).
  • the recesses (6) on the valve sleeve (3) are T-shaped and the valve sleeve (3) may be engaged and disengaged from the valve body (4) by turning to align the projections (5) with the openings (not shown) to the recesses (6) in a bayonet type connection whereupon the spring (10) pushes the valve sleeve (3) with the O-ring seal (11), valve (7) and rubber sealing member (8) outwardly.
  • the spear valve assembly is kept in position in the keg neck by the locking ring (2), the screw threads of which engage with cooperating screw threads on the inside of the keg neck.
  • the spear valve assembly In order to prevent the spear valve assembly from being blown out unintentionally by residual pressure within a keg on removal of the locking ring (2), the spear valve assembly is provided with safety devices as shown.
  • the down tube (9) of the valve body (4) has a bell-shaped outer portion (13).
  • the portion (13) is formed with a plurality of arcuate openings (14) for the throughflow of beer during filling and a longitudinal slot (15).
  • the safety device of this embodiment comprises a safety lock plate (16) clearly shown in Figure 5.
  • the lock plate (16) includes retaining tangs (17) and (18), a pivoting retaining arm (19) and a locking ear (20) which projects outwardly and, when assembled, projects through the slot (15).
  • the retaining tang (17) and retaining arm (19) prevent the safety lock plate (16) being forced out of the slot (15).
  • the retaining tang (18) prevents inward movement of the plate (16).
  • the rubber sealing member (8) of the beer valve (7) provides a resilient backing to the plate (16) allowing pivoting movement as will be explained but preventing total inward displacement.
  • the locking plate (33) extends sufficiently far to engage behind the edge (35) of the keg neck (21) (or insert if present) and engagement with the reaction plate (32) prevents the spear valve (1) from moving any further.
  • Figures 16 to 19 disclose a seventh embodiment of safety device for a safety spear valve (1) normally locked in a keg neck (21) by a locking ring (2) and in which the valve sleeve (3) is integral with the locking ring (2).
  • the valve sleeve (3) has a depending skirt (37) and an inner annular shoulder (40).
  • the depending skirt (37), as shown in detail in Figure 19, has a plurality of arcuate openings for throughflow of beer during keg filling and a smaller opening (41) having an inwardly directed tang (42).
  • the valve body (4) comprises a depending down tube (9) flanged at an outer end to provide a seating for the annular rubber valve seal (8).
  • the rubber seal (8) is biassed against the shoulder (40) by an helical closure spring (43) which acts against the rubber seal of the down tube (9).
  • the valve body (4) also includes the valve (7) located within the down tube (9) and having an annular outer shoulder.
  • the valve spring (11) acts against the shoulder of the valve (7) biassing it into a closed position sealing against one surface of the rubber seal (8).
  • the spear valve In order to insert the spear valve into the keg, the spear valve is entered into the keg normally until it meets resistance caused by the locking tang (46) riding on the bottom seal shoulder (35) of the keg neck (21). Continued firm pressure will cause the spring steel of the locking tang (46) to flex towards the centre line allowing it to be forced past the shoulder (35). Once past the obstruction, the tang flexes back into its inclined position. The spear valve now screws home into its normal position and operates as a conventional spear valve.
  • a purpose made overstroking tool is inserted into the spear valve. This causes a compression in the spring (43) and forces the retractor plate (45) downwards and inwards by engagement with the inward tang (42).
  • the retractor ears (49) in turn, in a camming action, force the safety lock plate (44) towards the centre line, withdrawing the locking tang (46) and allowing the spear valve assembly (1) to be removed from the keg neck (21) normally.
  • This device allows the complete spear valve to be inserted and removed from the keg safely.
  • the retractor cam plate (60) is assembled between the closure spring (43) and a flared end (63) of the down tube (9).
  • the plate (60) has an operating slot (64) and is made of spring steel material which is bent at (65) to provide a resilient bias to the safety lock plate (61).
  • the safety device comprises one or more pivoted locking members.
  • pivoted members are preferred, any member which is biassed outwardly either by gravity or spring means which, in use, increases the outside lateral dimension of the spear to a dimension greater than that of the keg neck may be used.
  • FIG 24 alternative bayonet recesses (51) (only one shown) for a valve sleeve (52) of the type of spear valve assembly shown in Figure 1 are disclosed.
  • the recesses instead of being T-shaped, have a locking position (53) which receive the internal protrusions (5) on the valve body (4).
  • a rubber seal (as shown dotted) is applied which means that the down tube and valve sleeve (52) cannot be separated from one another without removal or destruction of the seal (54) because the protrusions (5) are unable to be moved to the outlets (55) to the recesses.
  • This arrangement prevents the assembly becoming dismantled during removal and therefore prevents possible blow-out of the valve despite retention of the down tube.
