Definitions

  • the device in its disclosed lubricator form includes a casing which is connected into a fluid (generally air) stream with a lubricant container in the casing.
  • the container includes a bag of flexible material and the fluid stream is caused to impinge on the bag so as to flatten it and expel the lubricant through the nozzle into the stream.
  • the air can befiitered while passing through the casing but prior to it being dosed.
  • a method of dosing a flowing fluid which comprises placing in the flowing fluid a bag containing an additive, the bag being of flexible material ing fluid to impinge on the bag so as progressively to collapse the bag and expel the additive into the flowing fluid through the nozzle, the fluid flow across said nozzle being such that a venturi effect is created, the resulting low pressure area being where additive emerges from the nozzle and enters the flowing fluid.
  • a container having an additive therein, the container comprising a bag and a nozzle,
  • the bag being of flexible material which is impervious to the additivecontained therein, the bag further being such that when a flowing fluid impinges thereon with sufficient force it progressively collapses to expel additive therefrom throughthe nozzle.
  • a device for dosing a flowing fluid comprising a casing having an inlet and an outlet by means of which the device can be connected into afluid flow line,.
  • an additive container in the casing comprising a bag and a nozzle, the bag being of flexible material which is impervious to the additive contained therein, the bag further being such that when aflowing fluid impinges thereon with sufficient force it progressively collapses to expel addi tive therefrom through the nozzle, the fluid flow path within the casing being such that the fluid flowing therethrough impinges on said bag to collapse the same and expel additive .
  • said casing includes a main part and a closure partwhich are releasably connected together, said container being connected to the closure part but lying wholly or mainly within said main part, so that as said closure part is separated from the main part, said container is simultaneously withdrawn from the main part.
  • said main part and said closure part are connected to one another by resiliently deformable fingers which are carried by said closure part and have their free ends engaged with an internal groove of said main part, said fingers being formed with cam surfaces which co-operate with cam surfaces of a cam ring,'the arrangement being such that rotation of said cam ring causes the cam surface thereof to act on the cam surfaces of said fingers to deform them inwardly and disengage said free ends from said groove.
  • said fingers to be formed with further cam surfaces which co-operate with cam surfaces of a component of said closure part, the pressure of fluid flowing through said casing, in tending to separate said main and closure parts, causing'said cam surfaces of said component to engage with the further cam surface of the fingers to urge the fingers outwardly into said groove.
  • said container can include a non-retum valve for preventing flow of fluid into said bag through the nozzle.
  • a connector for securing one componenthaving an annular groove to a further component which includes a cam ring and a plurality of resiliently deformable fingers, free ends of said fingers, in the secured condition, being entered in said groove, the cam ring and fingers having cooperating cam surfaces arranged so that rotation of the ring causes said fingers to be deformed as said cam surfaces of the ring act on the cam surfaces of the fingers and relaxed as the cam surfaces of the ring disengage from the cam surfaces of said fingers, the action of the cam ring on said fingers causing said free ends to enter. and leave said groove.
  • FIG. 1 is alongitudinal section through a lubricator
  • FIG. 2 is a fragmentary section through a modified form of lubricator.
  • the main part 14 has one end thereof in the form of an internally threaded inlet 18 to which an air hose (not shown) can be connected.
  • the other end of the main part 14 is open and two internal groove s'20 and 22 are formed adjacent this open end.
  • The: groove 20 serves to receive a seal 24 which can, as illustrated, be an O-ring and the groove 22 serves to receive locking elements as will be described in more detail hereinafter.
  • a generally cylindrical liner 26 is. fitted into the main part 14.
  • the liner 26 includes an end ring 28 which is a tight fit in the part 14 and which abuts the internal shoulder 14.1 of the'part 14.
  • three arrays of pads 30 can be provided and each array of pads can consist of three pads, the pads being relatively short in the circumferential direction so that they are widelyspaced apart in this direction and thus do not hinder fluid flow in the cylindrical space referenced 32 which exists between the. outer surface of the liner 26 and the bore of the part 14.
  • the liner 26 At its left-hand end (as viewed in FIG. 1) the liner 26 includes a cone 34 the apex of which faces the inlet 18 and which almost completely closes that end of the generally cylindrical part 26. 1 of the liner 26.
  • the cone 34 acts as a filter and a ring of apertures 36 is provided around the periphery of the 40.1 at one end and an internally screw-threaded connector portion 40.2 at the other end.
  • This connector portion 40.2 forms an outlet and is intended for attachment to an air hose, or directly to a pneumatic machine, and the portion 40.1 co-operates with the seal 24.
  • a spigot 42 having a central aperture 44 for receiving a lubricant container 46 is screwed into the left hand end of the component 40.
  • An air filter 48 of cylindrical form is held between the shoulder 40.3 of the component 40 and a collar 42.1 of the spigot 42. It will be noted that the collar 42.1 enters the left hand end of the liner 26 and substantially closes that end. Only a restricted circular exit 26.2 exists between the collar 42.1 and the liner 26.1.
  • the air filter 48 is centered by its collar 48.1 and can consist of a cylinder in which a plurality of narrow, circumferentially extending cuts have been made. Each cut is interrupted in three or four places, the effect of this being to provide a filter which includes three or four longitudinally extending ribs which are connected to one another by a large number of circumferentially extending, closely spaced filter elements.
  • a ring of bores 50 is formed in the spigot 42, the bores 50 being inclined with respect to axis of the spigot 42. These bores connect the space 32 to the out let and it will be seen that the filter 48 is between these bores and the space 32.
  • a retaining ring 52 is screwed onto the component 40 and holds a cam ring 54 and a plurality of locking fingers 56 in place.
  • the ring 54 is formed internally with a number of cam surfaces which co-operate with corresponding cam surfaces on the fingers 56.
  • each finger 56 is, in the position illustrated, in the groove 22.
  • the fingers 56 are of resilient material such as nylon.
  • the main casing part 14, the component 40, the spigot 42, the air filter 48, the retaining ring 52 and the cam ring 54 can also be made of this material.
  • the component 40 is formed with a sloping, annular cam surface 40.4 which co-operates with a cam surface 56.2 formed onfeach finger 56 for the purpose to be described.
  • the fingers 56 are, at their right hand ends, integral with a ring which encircles the component 40 between it and the ring 54.
  • the lubricant container 46 includes a bag 46.1 which holds the lubricant and a nozzle 46.2 through which the lubricant feeds from the bag.
  • the nature of the bag 46.1 will be dealt with subsequent to the description of the manner in which the lubricator operates.
  • the lubricant can be a fluid or a particulate solid such as graphite or a grease.
  • the nozzle 46.2 is formed with two circumferential ribs 58 which co-operate with two circular grooves 60 formed in the aperture 44.
  • the effect of the nozzle 46.2 will also be dealt with in more detail after the description of the manner in which the lubricator operates. It will, however, be noted at this stage that a non-return valve can be provided in the bore 46.3 of the nozzle which valve, while permitting lubricant to flow from the bag 46. 1, prevents fluid flowing into the bag through the nozzle. Additionally, a grease nipple (not shown) can be provided for enabling the bag 46.1 to be refilled. I
  • the inlet 18 intended, as described, to be connected to an air hose which itself leads to a source of air (not shown) under pressure.
  • the connector portion 40.2 is connected by a further air hose to, or is screwed directly onto, the pneumatic apparatus which is to be driven and lubricated.
  • Such apparatus can be, for example, a pneumatic hammer or drill.
  • Relatively large dirt particles contained in the incoming air impinge on the cone 34 are guided by its sloping surface to the ring of apertures 36 and collect in the space which exists between the cone 34 and the lubricant bag 46.1.
  • the bulk of the flowing air passes through the ring of apertures 38 into the space 32 and then through the air filter 48 to the bores 50.
  • the air filter 48 removes the finer contaminating particles.
  • the flowing air impinges on the left hand end of the bag 46.1, the kinetic energy of the air slowly collapsing the bag 46.1 so that the lubricant in the bag is squeezed through the bore 46.3 of the nozzle 46.2 and is entrained by the air stream.
  • the position of the bores 40 is such that a venturi effect is created across the nozzle 46.2 and this in turn creates a low pressure area where lubricant emerges from the nozzle.
  • the venturi effect is not essential and need only be created if the viscosity of the lubricant makes it necessary.
  • Changes in static pressure can be obtained by varying the size of the exit 262. If this exist is completely eliminated then all the air must flow through the space 32. However, even in these circumstances the lubricator still functions as desired provided the cone 34 is removed or is so constructed as to permit the incoming air to impinge in a substantially unhindered manner on the bag 46.1. This step can only be taken if the incoming air is relatively clean and contains no particles which may puncture the bag.
  • the cam ring 54 is turned so that its internal cam surfaces co-operate with the cam surfaces of the fingers 56 and resiliently deform these fingers inwardly.
  • the free ends 56.1 are thus disengaged from the groove 22 and the closure part 16, together with the lubricant container 46, can be withdrawn from the main casing part 14.
  • the liner 26 remains in the part 14 and any particles which have collected therein can be emptied out at this stage.
  • cam surfaces of the cam ring 54 are symmetrically arranged so that the ring can be turned in either direction to lock the casing parts together or to release them.
  • the illustrated lubricator can be used for this purpose by connecting the inlet 18 to the source of water and the connector portion 40.2 to the bore hole being drilled.
  • the non-return valve in the nozzle 46.2 is desirable for it prevents contamination of the contents of the bag 46.1 when, for any reason, flow of water through the lubricator ceases and under which circumstances there might be some reverse flow into the bag.
  • the non-return valve can prevent contamination of the bags contents when a gas other than air is being fed through the lubricator which gas might, if it feeds into the bag 46.1, have an adverse effect on the flow capabilities of the lubricant.
  • the bag 46.1 is of a flexible material which is impervious to the lubricant contained therein and which, preferably does not have any significant inherent resilience.
  • the flexibility of the material of the bag enables it to collapse progressively under the influence of the air (or other fluid) which impinges thereon with sufficient force. If the material of the bag does have any significant inherent resilience then, when in its full condition, the material of the bag must not be stretched for if it is stretched then it tends to contract under the influence of the forces thus set and squeezes lubricant through the nozzle. As the bag progressively empties these forces decrease and it is thus impossible to ensure the requisite even flow. Thus if resilient material is used the bag should not be filled beyond its natural, unstretched volume.
  • Suitable materials for the bag 46.1 are paper of sufficient strength which is impervious to the lubricant, cotton or other fiber re-inforced sheet plastics material, sheet plastics material such as polythene, neoprene, rubber, or rubber re-inforced materials. Each of these materials is sufficiently flexible to be collapsed progressively by the air impinging of them.
  • the illustrated bag is of sheet plastics material with the end remote from the nozzle closed by a transversed weld.
  • the length of the bore 46.3 influences the rate at which lubricant feeds from the bag.
  • the bore 46.3 is initially blocked by a solid spigot formation 46.4 which is cut off to open the bore 46.3 immediately before the nozzle 46.2 is inserted in the aperture 44.
  • the spigot 46.4 formation is cut off at its juncture with the main part of the nozzle and this ensures that the bore 46.3 always has the requisite length. If, however, this arrangement is not used then some other mark, such as a notch in the spigot, is employed to ensure that the spigot is always cut off at the same point and thus leaves behind a bore of standard length. With this arrangement the part of the spigot between the notch and the main part of the nozzle must be hollow.
  • the lubricator illustrated therein differs from that of FIG. 1 in three respects. Firstly, the spigot 42 is shorter and does not screw into the component 40. Shortening the spigot 42 has the effect of eliminating the bores 50 so that the venturi effect discussed above is no longer obtained. Secondly the filter 48 is integral with the spigot 42 and screws into the sealing portion 40.1 to connect the spigot 42 and component 40.
  • the third change is that the fingers 56 have the modified shape illustrated and are integral with the ring 56.3.
  • Each finger has associated therewith a single cam surface (not shown) and a circumferentially extending locking detent 54.1, the detents 54.1 and camsurfaces being circumferentially spaced on the cam ring 54.
  • Each detent 54.1 has one of its circumferential ends fast with the ring 54, the remainder of each detent and the inner surface of the ring 54 together defining an arcuate slot for receiving the associated finger 56.
  • the detents 54.1 in the locked position, prevent any inward motion of the fingers 56 and also act as end stops to limit the angle through which the cam ring 54 can turn.
  • a device for dosing a flowing fluid comprising a disposable additive container and a casing, the casing having an inlet and outlet by means of which it can be connected into a fluid flow line and having means therein for temporarily and releasably locating one of said containers, the casing being adapted to be opened to permit access to be had to said means, and the container comprising a bag and a nozzle, the bag being of flexible material which is impervious to the additive contained therein, and further being such that when impinged upon by a flowing fluid with sufficient force it progressively collapses to expel additive from the nozzle, and the nozzle including a bore leading from the interior of the bag and a removable formation blockingthe end of the bore remote from the bag which formation, when removed, leaves behind a bore of predetermined length, said casing being so formed that the fluid flow path therein is such that the fluid flowing therethrough impinges on said bag to collapse the same and expel additive which is then entrained in the flowing fluid.
