Definitions

  • the present invention relates to liquid dispensing devices and more precisely to animal watering devices in which the liquid dispensing to a drinking animal takes place by that the animal itself actuates some type of operating means opening and closing a valve.
  • valve mechanism in such dispensing devices comprises a valve cone or plate sealing against circular valve seat through which a valve stem from the valve cone or plate extends.
  • the valve is opened when the cone or plate is forced from the seat or tilted in relation thereto and returns to closing position by the aid of a spring and/or the pressure of the liquid as soon as the actuation by the animal ceases.
  • the watering device shown in said specification comprises a tubular housing one end of which is provided with an external mounting thread and the other end of which being intended to be brought into the mouth of a drinking animal.
  • the dispensing end of the housing is bevelled or has a cut-away portion from a plane through the axis of the tube and backwards and upwards.
  • an operating means is accessible which a drinking animal is pressing against the underlying portion of the housing for opening the valve for the liquid through-flow.
  • the present type of watering devices is well known and widely used. However, it shows the drackback that it is expensive to manufacture due to the fact that it consists of many parts which are to be manufactured and mounted together and some of said parts are of such a shape that they request complicated manufacturing operations. Also the bore through the tubular valve housing must be given a rather extensive working so that the necessary shoulders and grooves are obtained. A result thereof is also the fact that the watering device is difficult to renovate.
  • the problem of the more solid operating means or nipple relates more to the manufacturing thereof as the annnular valve seat is to be located between the operating means and the valve plate, around the valve stem extended therebetween.
  • the valve seat normally is constituted by a shoulder in the housing of the watering device it has been necessary to have either the operating portion or the valve plate possible to remove from the valve stem in order to make assembling possible.
  • the housing has also contained other shoulders for restrictions, screens and similar.
  • Such an embodiment has also involved many working operations for the manufacturing of the housing and of course also for the operating means including valve parts, as well as for the mounting of the many parts.
  • valve mechanism When the valve mechanism includes a valve plate normally occupying a vertical position and which is depressed by the repeated tilting of the valve stem for opening of the valve, it occurs that the lower edge of the valve plate wears into the valve housing. This does not mean that the valve starts to leak but it is getting more and more difficult to open to a sufficient degree due to the fact that the distance between the operating means and the underlying portion of the tubular housing is so small that when depressing the operating means the tilting of the plate is insufficient for a satisfactory opening of the valve in order to give a satisfactory water flow therethrough.
  • the object of the present invention is to remove the above problems. This object is reached by a structure of the type referred to in the claims from which also the particularly characterizing features of the invention are clear.
  • FIG. 1 is a longitudinal section through one embodiment of a watering device in accordance with the invention
  • FIG. 2 is a longitudinal section through a second embodiment of the watering device in accordance with the invention.
  • FIG. 3 is a longitudinal section through a third embodiment of the watering device in accordance with the invention.
  • the embodiments of the watering device in accordance with the invention shown in the drawings include a tubular housing 1 the bore 2 therethrough by a shoulder 3 being divided into two portions, a valve portion 4 and an outlet portion 5, the diameter of the outlet portion 5 being slightly less than that of the valve portion 4.
  • Valve portion 4 is provided with an external thread 6 for mounting of the watering device 1 to e.g. a water supply conduit in a conventional way.
  • the outlet portion 5 is bevelled or angle-cut at 7 from a plane through the axis 8 of the tubular housing 1 and backwards and upwards so that an opening 9 is formed which from above looks like a half-ellipse.
  • the shoulder may be manufactured in such a way that it is rolled into the housing 1 and will then be constituted by an annular ridge. In such a case the valve portion 4 and the outlet portion 5 are of the same diameter.
  • the shoulder may also be constituted by a resilient ring which is mounted into a groove cut in the internal wall of the housing.
  • an operating means or nipple 10 in the outlet portion 5 and this is of a slightly less diameter than the internal diameter of the outlet portion 5.
  • the operating means 10 extends from a position inside the opening 9 and nearly up to the outer end of the outlet portion 5. Thereby, a portion of the operating means 10 will be exposed in the opening 9 so that an animal opening its mouth over the watering device will be able to depress the operating means 10 for opening the flow-path through the watering device. Due to this solid operating means 10 as well as its protected location a drinking animal can neither hurt itself nor give rise to any deformation of the operating means and the valve mechanism belonging thereto.
  • valve stem 11 From the operating means or nipple 10 there is extended a valve stem 11 to a valve plate 12 the diameter of which being the same or slightly greater than the one of the operating means 10.
  • a washer 13 extended around the stem 11 is resting against the shoulder 3 and preventing the valve mechanism from sliding through the bore 2.
  • Valve plate 12 is provided with a protrusion 14 constituting a guide for a spring 15 biasing the valve plate 12 against its seat 16 in turn kept in place by
  • valve seat 16 is constituted by a bead at the inner end of the insert 17.
  • insert 17 is provided with a similar bead 18 gripping around the edge of a restriction 19 and keeping it in place.
  • Spring 15 is clamped between restriction 19 and valve plate 12 and is pressing the valve plate 12 against the valve seat 16.
  • the housing 1 as well as the operating means 10 together with the stem 11 and the valve plate 12 are preferably made of metal such as stainless steel or brass but also some wear resistant plastic is conceivable.
  • the operating means 10, the stem 11 and the valve plate 12 with the protrusion 14 are in this embodiment made of one and the same piece which results in a very simple manufacturing of this detail.
  • the insert 17 is made of a flexible material such as natural or synthetic rubber or plastic.
  • the assembly of the watering device is very simple.
  • the washer 13 which is split and of resilient material is bent open and thread over the valve stem 11 and is thereafter due to its resiliency allowed to return to its original shape.
  • the bead- shaped valve seat 16 of the insert 17 is stretched over valve plate 12 to the position between the plate and the washer 13. Thereafter, the insert 17 together with thereto assembled parts is brought into the valve portion 4 to the position in which washer 13 rests against shoulder 3.
  • spring 15 is inserted into abutment against the valve plate 12 and is clamped between the plate and the restriction 19 which is locked in place by the fact that the bead 18 of the insert 17 is stretched over its edge. It is also possible to carry out the whole assembly of the parts within the insert before
  • the embodiment of the invention shown in Fig. 2 differs from the one in accordance with Fig. 1 by the fact that the restriction 19' constitutes a portion of the insert 17'.
  • the mounting has to take place in such a way " that first spring 15' is inserted in the insert 17 before the bead-shaped valve seat 16' is stretched over the valve plate 12.
  • washer 13 should preferably have been mounted onto the valve stem 11.
  • the insert 17' in the way mentioned is brought into the valve portion 4 of the housing 1.
  • insert 17' may be made of a slightly harder material. Then, in order to get the valve plate 12 mounted in the insert, the insert may be completely or to some extent split whereby the insert can be widened sufficiently to allow plate 12 to be brought in place.
  • valve seat is preferably constituted by an 0- ring which can be stretched over the valve plate in order to get in place.
  • both the shown embodiments of the watering device in accordance with the invention can be made of stiff material and even if this should be so stiff that cutting and bending apart of the insert 17, 17' in order to get the valve plate 12 in place not should be possible but this had to be mounted in some other way, e.g. by screwing as previously mentioned an essential saving of work and parts is made in comparison with the watering devices mentioned in the preamble due to the fact that the valve portion of the watering device is located in a simple insert which is easy to mount and to replace.
  • valve insert 17, 17' is sufficiently stiff in order to constitute itself a valve seat support corresponding to washer 13.
  • the operating means 10 must in this connection be ⁇ JO attachable to the valve stem 11 by e.g. screwing but such increase in the costs are more than well saved by the lower price of the housing 1.
  • the insert 17, 17' is kept in place by the fact that it at the outer end is provided with 5 some sort of protrusion or bead as shown in the drawings whereby the insert is prevented from passing through the housing 1.
  • the bead or valve 0 seat 16" constitutes a portion of an insert 17" of flexible material which also extends around the periphery of the valve plate 12 in the shape of a skirt 18".
  • This skirt 18" acts as a guide for the valve plate 12 and prevents the valve plate 12 from wearing into the housing 1 itself for which there is a 5 risk as previously mentioned.
  • the insert 17" is made of a stretchable material such as natural or synthetic rubber or plastic.
  • the assembly of the valve mechanism is very simpl e.
  • Washer 13 " which is split and of a res ilient material is bent apart and thread over the valve stem 11 whereafter it is allowed to return to its original shape.
  • the bead-shaped valve seat 16" of the insert 17" is stretched over the valve plate 12 to a position between the plate and washer 13 ", the skirt 18 " surrounding the periphery of the plate 12.
  • the ins ert 17 " is of such a stretchable material that it easily returns to its original shape the valve seat 16 " will not be deformed by such an operation.
  • valve mechanism In order to get the valve mechanism in place in the hous ing there is us ed a suitable tool whereby the bead- shaped valve seat 16" will rest correctly against washer 13 " which in turn rests against shoulder 3.
  • spring 15 In this ins erted pos ition, spring 15" is located into engagement with the valve plate 12 and is clamped against the restriction 19" which with snap-in action locks into a groove in the outer portion of the valve portion 4.
  • the insert 17 " could be made from a non- stretchable material. Then the assembly requires that the insert is split and can be stretched out over the valve plate or that stem 11 could be made free from either the valve plate 12 or the operating means 10. Thereafter, the s lit has to be seal ed by glue or tape and preferably, in such connection an 0-ring is u s ed as a valve s eat whi ch wi thout d e form ation c an b e stretched over the valve plate in order to be brought in place. Although these embodiments might be more expensive than the one to be preferred they are, in spite of this fact, cheaper than the conventional embodiment.
  • the axis of the valve stem 11 will be located above the axis 8 of the device but after use during a long time the axes will coincide.
  • the insert is provided with some type of positioner such as a projection matching into a corresponding recess in the housing.
  • the watering device will then have during all its life a satisfactory water-through flow.
  • the portion of the insert 17 surrounding the plate 12 may be provided with inwardly directed ridges which are axially extended and which are forming flow channels therebetween.
  • an animal watering device having at least the same good operational characteristics as previously known similar devices. Due to the internal structure thereof the watering device in accordance with the present invention is essentially cheaper both to manufacture and to assemble than the ones previously known simultaneously as the advantage is obtained that it can be renovated without particular equipment.
