PR IMER VALVE Inventor DAV/D S. WILLIAMS a ttorneg Patented July 24, 1934 STATES ATENT OFFICE 9 Claims.

This invention relates in general to improvements in valves and particularly to primer valves which are automatically actuated by water passing through a standard water supply line and in this manner by-pass some of the water into any trap where water is essential either to act as a gas seal or for any other desirable purpose.

My invention contemplates the use of a primer valve which may be automatically actuated so 10 that water is at all times maintained in floor drain traps, sumps or other analagous contrivances which, either by statutory provisions or by the desire of individuals, require a water seal at all times so that obnoxious gases cannot emanate from the disposal units through the floor drain trap, sump and the like.

The primary object of my invention is to provide means for preventing the emanation of undesirable gases through drains of every sort and description and to provide means for preventing foul water and air to be siphoned into the water supply line.

An important object of my invention is to provide a valve which, when installed directly or indirectly-in a water supply line running'to or from any service connection, will automatically maintain a predetermined amount of water in a trap, sump or other analogous device so that the same will act as a seal against escaping obnoxious gases and will also compensate for water losses in the trap or sump due to evaporation, leakage or other causes.

A still further object of my invention is to provide a simple, practical, inexpensive and efficient primer valve which may be manufactured at low cost and Within a minimum of time.

Another object of my invention is to provide means for maintaining the valve in seated position until the pressure of'the water running 40 through the water supply line unseats the valve and permits some of the water to escape and flow into the trap, sump or other analogous device.

An equally important object of my invention is to provide means for automatically lay-passing a liquid flowing through a standard supply line into a container which must either be sealed or which may in turn actuate other mechanism such as a fire alarm connected toa sprinkling system.

To attain these and other objects and advantages, I employ somewhat diiierent principles from those set forth in my two co-pending divisional applications for the improvements in Primer valves, bearing Serial Numbers 714,210

Corresponding parts are identified by the same reference characters. 7

In carrying out my invention disclosed in the drawings, I employ a valve body herein generally designated by reference character A. The valve body has in general twotubular bores, one extending vertically and the other horizontally with respect to the valve body. The valve body has aboss 1 extending from one side thereof in which is incorporated internal threads 2. A conduit 1A leading from a source of water is threadably engaged to boss 1. Another boss 3,

having external threads 4 thereon,-extends from the valve body and is in direct opposite alignment with boss 1. A conduit 3A, which is connected to any service outlet or outlets is threadably disposed relative to boss 3. A diaphragm 5 divides the passageway formed between bosses 1 and 2 into chambers 6 and 7. Opening 8 disposed through diaphragm 5 connects the cham bers 6 and 7, and..port..9 permitsthewater to drain from chamber-"6 to' chamber 7 to thereby equalize the pressure within the respective chambers when the water supply is shut off.

Still another boss 10 extends upwardly frome disposed about the connection 30 and normally covers openings 36 and 3'7. It will be seen from Figure 3 that the union-connection 30 may be connected to a drain trap 39. This disclosure, however, should not be considered a limitation of the invention to such use only as the invention is adapted for other uses as well. Attention might well be called to the fact that the vent assembly fulfills several important functions. Not only does the vent assembly permit inspection. and 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 the ValVe y A and has internal threads 11 which the vent assembly is connected. Thus the therein Which Permit threaded h p possibility of foul water and air in the drains bebe secured thereto.

and extending into chamber 55, is a hollow stem or supply-tube '71, which has a flange '72 at one end and an opening 73 at the oppositely disposed end. The supply-tube '71 is positioned so that its opening is in registerable alignment with the valve-washer 6'7, which normally is seated against seat '74 formed at the free end of the supply-tube 71. In this manner, the supply-tube 71 is normally maintained out of communication with the chamber 54; and it is only when the pressure of the water coming from the source of supply swings the weighted disc about shaft 59 that the valve-washer 6'7 is removed from its seat and permits opening '73 to communicate with cham- A union-connection '75 has its bore 76 in registerable communication with the passageway formed within supply-tube '71 when it is joined to the supply-tube by union-coupling '7'7. An air vent opening '78 extends upwardly from the uniomconnection '75 and has a slip-cap '79 disposed thereon with a portion thereof being in spaced relationship thereto to form an air vent as shown at 80.

Equally effective results maybe received by a primer valve constructed in accordance with the disclosure shown in Figure 8, which is generally designated by reference character D, and it embodies another modified form of the invention. This valve has incorporated therein the same number of bosses and has connected thereto the same type of union-connection as is shown in Figures 1 and 2; Some changes, however, have been made in the valve mechanism proper. It should be noted that a flange-guide 81 extends fupwardly from boss 14 and that boss 14 has removably disposed therein a hollow stem or supply-tube 82. This supply-tube has a flange 83 at one end thereof and an opening 84, which communicates with the hollow interior thereof at its opposite end. A head-cap 85 is threadably secured to the boss 10 and has chamber 86 therein as well as a flange guide 8'7 at its base. The valve stem 88 has a valve-washer 89, which is removably secured to one end of the valve-stem and is adapted to rest against opening 84 in supply-tube 82. A weighted flange 25 is secured to the valve-stem so that it lies immediately above the diaphragm 5. The stem is guided in its vertical movement by guide-flanges 81 and 87. A: supply port 90 is disposed through the flange guide 81, and is adapted to keep a ready supply of water around the supply tube 82, ready to enter thereinto when the valve-stem is raised and opening 84 is uncovered.

M odus operandz' The operation of the valve may now be explained. As indicated in Figure 1, the piston valve is seated on the valve-seat. Assume now that water under pressure is passed into chamber 6. Since water follows the course of least resistance, it will enter space 29 as well as opening 8, and, in so doing, the water will strike flange 25 and raise the piston valve assembly. The opening 21 will then be uncovered so that the water may enter into supply-tube 18. When the water supply is shut off, the weight of the piston valve assembly will force the valve-washer to cover up the openings 21. Figure 2 illustrates the position which the piston valve normally occupies when the water under pressure passes through valve-body. The primer valve illustrated in Figure 8 operates in substantially the same manner.

"Similar action takes place when a structure manufactured in accordance with the disclosure in Figure '7 is used. The water under pressure entering chamber 52 swings the weighted disc 62 so that the water enters chambers 53 and 54, and, when the disc is swung from its normal position, valve-washer '14 is removed from opening 66, thereby permitting the water to enter into supply-tube '71.

This completes the detailed description of the elements applied in my invention, and, from the foregoing description, it will be seen that I have produced valve-mechanisms which substantially fulfill the objects of the invention set forth herein.

While this specification sets forth in detail the present and preferred constructions of the inventions, still in practice deviations from such detail as come within the skill of the mechanic may be resorted to but which do not depart from the spirit ofthe invention herein.
