9 Claims.
This invention relates in general to improvements in valves, and particularly to primer valves which are adapted for automatic actuation by water pressure that normally is contained in a Q water supply line but which utilizes somewhat Y 1sY different mechanical principles from those set forth in my co-pending application for improvements Primer valves, Serial No. 704,637, filed December 30, 1933, out of which this application has been divided to comply with rule 41 of the rules of 'practice in the United States Patent Office, and from those set forth in my copending divisional application for the improvements in Primer valves, Serial No. 714,805, iiled March 9, 1934.
v'Ihe subject matter of this application is capable of fulfilling all of the objects set `forth in the above-identified co-pending applications, insofar as the subject matter common to the three is concerned, and, while the device illustrated as usually generated in sewers andother disposal units cannot enter into houses orfbuildings'from such sewers or other disposal units.'
A11-important object of my invention is to provide a valve which, when installed directly or indirectly 1n a water supply line running to or from any service connection, will automatically maintain a predetermined amount of water as a seal against escaping obnoxious gases and/ or will compensate for water losses in devices connected thereto due to use, evaporation, leakage or other causes.
` An equally important object of my invention is to provide means for preventing foul water and air to be siphoned from any drains into the water supply line.
A still further object of my invention is to provide a simple, practical, inexpensive and emcient primer valve which may be manufactured at low cost and withinV a minimum of time.
The invention is directed to other objects and possesses other features of novelty and advantage and consists in the new and useful formation, construction, combination and'interrelation of parts, members and features, all of which will be more apparent from the followingA detailed description, having reference to the accompanyi ingvdrawing -which; illustrates two Vembodiments by which the invention may be realized and in which:
Figure 1 is a sectional, side view of a priming unit embodying my invention, showing the position of the valve when the liquid in thesupply line is at rest.
Figure2 is a sectional, side view of a primin unit embodying my invention, 4showing the position of the valve when the liquid in the supply line is in motion.
Figure `3 is a fragmentary, side View, partially in section, of the priming unit illustrated in Figures 1 and 2, showing, in` addition, a resilient member positioned in such manner as to normally maintain the movable portion of the valve in the position shown in Figure l.
Figure 4 is a sectional, side view of a priming unit embodying a slightly modified form of my invention, showing the position of the valve when the liquid in the supply line is at rest and further showing a slightly modified form of vent arrangement.
Figure 5 illustrates a water supply line to which a standard type of faucet is attached and also to which a priming unit embodying my invention is directly connected and further indicating the manner of connecting said unit to a water trap.
Corresponding and like parts are referred to in the following description and indicated in all of the views of the drawing by the same reference characters.
-The preferred form of my invention is completely illustrated in Figures 1 and 2, wherein reference character A designates generally'the priming unit. The valve-body or casing 1 has an internal threaded boss 2 and an external threaded boss 3 extending in the opposite direction from boss 1 but in direct alignment therewith. A dividing wall or diaphragm 4`separates the passageway formed between two bosses into chambers 5 and 6. The dividing wall or diaphragm 4 has an opening 'lvdisposed therethrough, whose circumference is materially less than the circumference of the inner wall-of the passageway. A port 8 is disposed through'the lower portion of the diaphragm 4, and assists in more effectively equalizing the pressure throughout the interior of the valve-body when the water supply is cut off.
' Internal threaded boss 9 extends upwardlyv from the valve-body 1 and head-cap 10 is threadably secured'thereto. The head-cap is formed with a chamber 11 therein into which enters aI portion of the'valve-stem 32, hereinafter tojbe more particularly described. A guide-flange 12 is'formed about the periphery of the chamber 11 and acts as a guide for the valve-stem 32. If it is desired to supplya resisting force. against the upper portion of the valve-stem 32 tobede-4 scribed, a resilient member 13, such as a rubber diaphragm, `may be placed Within the chamber 11, as graphically indicated in Figure 3, wherein there is shown the base 14 of the resilient member resting against the ceiling 15 of the head-cap 10 and the apex 16 of the diaphragm 13 resting 5 against the top of the valve-stem 32.
External threaded boss 17 extends downwardly from the valve-body 1 and is in direct alignment with the internal threaded boss 9. A flangeguide 18 extends upwardly from boss 17 into chamber 5. A hollow-stemor supply-tube 19 is removably disposed within the boss 17 so that the apex 20 of the supply-tube 19 is positioned below the ilange-guide 18. The supply-tube 19 has a flange 21, which rests against the face 22 of the boss 17. A restricted opening 23 is formed through the apex 20 of the supply-tube 19.
A vent-assembly 24 has a bore 25 therethrough. One end of the vent-assembly 24 has a fiange 26 adjacent its periphery, and the other end has an i internal threaded boss 27 formed therein. The vent-assembly 24 is connected to the valve-body 1 by placing the'flange 26 against the flange 21 so that the bore of the vent-assembly is in registerable alignment with the interior 28 of the supply-tube. Both of these flanges are held in connected relationship by union-coupling 29,
which. is threadably disposed on boss 17. A plurality of vent-openings 30 extend through boss 27,
and a canopy or Vent-protector 31 is slidably disposed about the vent-assembly 24 and normally covers the vent-openings 3). Attention might well beV called to the fact that the vent assembly fulfills several rimportant functions. Not only does the vent assembly permit inspection and i supply air to the supply tube, but it also eliminates the possibility .of a Siphon action taking place between the supply tube and the drain to which the vent assembly is connected. Thus the possibility of foul water and air in the drains being @n siphoned into the waterV supply line and contaminating the water therein is entirely prevented.
The movable member of the priming unit consists of a valve-stem 32 that has a resilient element 33, such as a valve-washer, removably secured to one of its ends. This end normally rests against opening 23 in the supply-tube 19 so that the washer effectively seals the opening in order to; preventanyr liquid entering into the interior 28 of the supply-tube when the liquid in the supply line is at rest; The valve-stem passes through the opening 7 in the diaphragm 4 and is held in relatively vertical `position by guide-flanges 12 an-d 18. A weighted iiange 34, whose outer circumference is substantially equal to the circumference of the opening 7, is secured to the valve-stem 32 and is positioned thereon, so that when the end of the valve-stem 3.2, which has valve-washer 33 therein, is at rest uponvthe apex 20 ofthe supply-tube, thus sealing opening 23, the base 35 of the mi weighted flange is placed immediately adjacent the upper portion of the diaphragm 4. By this arrangement the full weight of the valve-stem assembly is applied upon the apex 20 to seal effectively opening 23, and, at the same time, for 65, all practical purposes, to seal opening 7. A
supply-port 36, the function of which is to keep a ready supply of water around the apex 20 of the supply-tube 19 ready to enter within the interior 28 thereof when the valve-stem assembly is,
* body 1 shown Figuresl and 2,- but whose'inl terior is slightly modified. The chamber 11 of the head-cap 10 is smaller in area, thus eliminating the necessity or flange l2 shown in Figures l, 2 and 3. The diaphragm 4 illustrated in Figures 1 and 2 is modified so that there is provided a practically unrestricted passageway between bosses 2 and 3, thus providing a straight-way valve through which the liquid in a supply line may pass with greater freedom of movement, since the port 8 is materially increased in area as shown at 37 so that a greater proportion of water can pass directly from chamber 5 into chamber 6 instead of requiring a greater proportion of the liquid to pass through opening 7 into chamber 6 as required in the construction illustrated in Figures 1 and 2. Guide-flange 18 is' also slightly modied by reducing its over-all area ,and Lby adding thereto an additional supply-port 38. The valve-stem 32 is substantially identical in construction as that illustrated in Figures 1 and 2 with the exception that the circumferential area of the lower portion is materially reduced, thereby permitting the weight of the flange 39 to be materially reduced, but its circumferential area is still substantially identical to the circumference of the opening 7. It is obvious that the resilient member 13, illustrated in Figure 3, may also be applied to this modied form of the invention to perform the identical functions for which it is intended.
The vent-assembly 24 has also been slightly modif-led but performs the identical functions as the vent-assembly heretofore described. The modified form consists of an internal threaded member 40, which has a plurality of threaded arms 41 extending from the top 42 of the member 40 and inclining inwardly. These arms are threadably positioned upon the hollow-stern 43 cf the vent-assembly 24, and, by this construction, vent-openings similar to those illustrated in Figures l and 2 are automatically provided. A slightly modified form of protector or ventcover 44 is slidably positioned with respect to the stem 43.
There is illustrated in Figure 5 one of the valves directly connected with a supply line. Boss Z'has threaded therein conduit 45, coming from a source of water supply not shown, and conduit 46 yis joined to boss 3 by union-coupling 47. VConduit 46 is shown connected to a standard faucet 48, but it is obvious that conduit 46 may be connected to any other service outlet without affecting the operation of the invention. Boss 27, through proper conduit connections, may be joined with a drain trap 49 or with any 'other contrivances which require an intermittent supply of water. either for purposes of efecting a seal or for any other purpose. The application of this invention to a drain trap should not be considered a limitation to its use since the invention has a wide range of utility and may be applied to other arts and for other purposes.
Modus operandi It is well known that water systems are con? structed so that sufficient pressure is maintained in all supply lines either by natural or artificial means. t is the purpcse of the invention to utilize the pressure maintained within ywater supply lines for'permitting the automatic actuation of a valve in order' to permit someA of the VVwater within the lsupply line to bediverted and by'- passed for the purpose of producing a water seal or for any purpose where it is desired! to maintain automatically af substantially constantsups- 158 me Y ply of Water. When a service outlet is opened, the water within the supply line is put into motion and surges forward toward the valve assembly. As the water rushes into chamber 5, its flow is suddenly diverted by diaphragm 4, causing a turbulence of suiiicient force to raise the valve-stem assembly as the water seeks to enter chamber 6 through opening 7. When the valve-stem assembly is raised, opening 23 is uncovered and water is permitted to enter into the interior 28 of the supply-tube 19, as shown in Figure 2, and from there the water enters into the water-trap or any other contrivance to which the vent-assembly is connected. When the service 4outlet is closed, the surge of the water is reduced and the water in the supply line is put to rest and consequently the weight of the valve assembly is suiiicient to cause the valve-stem to reach its dormant position and to seal eectively opening 23, as shown in Figure l.
The invention has been described in connection with two specic, illustrative embodiments disclosing a denite arrangement of parts. However, it will be understood that a wide range of variants thereof are possible to those skilled in the art without departing from the broad spirit of this invention, since the invention, in its broader aspect, is not limited to the speciiic construction herein described and shown, as changes in the size, proportions, arrangements and mechanical relations as well as additions, lomissions and substitutions in the form or part may be made which fall within the scope of the subject matter incorporated in the appended claims.
