JOSEPH L. GROVES, OF LOS ANGELES, CALIFORNIA.
AUTOMATIC WATER-FEED DEVICE FOR STEAM-GENERATORS, OIL-Z BURNERS, 8w.
Application filed November 15,1915.
To all whom it may concern Be it known that I, JOSEPH L. Gnovns, a citizen of the United States, residing in the city of Los Angeles, county ofLos Angeles, State of California, have invented a new and useful Automatic Water-Feed Device for Steam-Generators, Oil-Burners, &c., of which the following is a specification.
This invention relates to an automatic liquid control valve.
An object of the invention resides in the provision of a device of this character by means of which a constant level may be maintained in a liquid container.
A further object of the invention resides in so constructing the device that its action will be positive in stopping the flow of liquid into the container.
Further to provide a feed water device especially applicable for use in automatic steam-generator oil-burners of the water reservoir type. Being designed, as it is, to be attached to the exterior of the liquid container, all its movable parts are kept cool by the in-flow of the liquid, and consequently are not subject to the accumulation of scale as are the devices designed for application to the interior of heated containers.
With these and other objects in view, such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims.
In the drawings Figure 1 is a longitudinal sectional view; Fig. 2 is a side elevation view of my vice;
Fig. 3 is an end view showing connection of float arm; and
Fig. 4 is a cross section view showing threaded stem.
Referring to the drawings wherein like parts are indicated by like characters throughout the several views:
My device consists of a body portion made of three sections detachably secured together. One of the end sections D is provided with threadson one end by means of which the section may be secured to the container L so that the float will extend within the same. On the other end of this section D is a hollow threaded shank with which a second section is detachably engaged which section is provided with a chamber G in the side adjacent the section D and another Specification of Letters Patent.

chamber in the side remote from the section D. To the second section a cap section Z is detachably engaged and has a reduced internally threaded neck for the reception of a liquid supply pipe N. Extending through the second section is a port P which establishes communication between the two chambers of the second section. The cap piece Z incloses a filter screen F for preventing foreign matter entering the port P. Extending through the section D is a port E which establishes communication between the chamber C and the container L.
In order that the flow of the liquid into the chamber C and through the port E may be automatically controlled, I have extended a valve stem S through the section D, which valve stem is in screw threaded engagement with the said section so that when rotated it will be moved longitudinally of the section D. Formed on the inner end of the valve stem S is a valve head V which is located in the chamber C and is adapted to close the adjacent end of the port P. The opposite endof the valve stem is adapted to extend.
into the container and has an arm'A adjustably mounted thereon which arm is held in place by a set screw Y and is provided on its end with a float G. This arm A extends at right angles to the valve stem S.
l/Vhen the device is attached to a container as shown in Fig. 1 and the water level is below a predetermined point, the valve head V will be in spaced relation to the adjacent end of the port P and the liquid will flow through the pipe N, through the port P and through the port E into the liquid container.
When the level of the liquid within the container reaches a' certain height the valve head V will close the port P and stop the flow of liquid into the container. It will be obvious that as the liquid level rises the float G will be raised gradually and the valve stem S rotated which action will force the valve head toward the port P until it closes the same as previously described. As the water is used from the container and the level drops the stem S will be rotated in the opposite direction and the port P opened. By making the arm A adjustable the amount of movement of the valve stem to close the port P may be varied and consequently the water level in the container varied.
From the foregoing description it will be seen that I have provided an automatic valve designed to be attached to the exterior of a liquid container for controlling the liquid level in the container which valve is so constructed that it will not readily get out of order and which is provided with a rotatable plunger for closing the inlet port which plunger is operated by means of a float.
W'hile I have illustrated and described a particular embodiment of my invention it has merely been for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that nu merous changes may be made in the details of construction without departing from the spirit of the invention or without exceeding the scope of the claims.
hat I claim is 1. A valve of the type described consisting of a body having helical grooves in the wall of the valve-stem opening and a channel parallel to the valve-stem opening, a valve seat spaced from the valve-stem opening within the body, and a stem turnably mounted in the valve-stem opening engaging with the valve seat.
2. An automatic water feed device for the liquid-container in steam generators, oil burners and similar places consisting of a body having means thereon to engage with the liquid container, the said body having also helical grooves in the wall of the valvestem opening and a channel communicating with the inside of the container, a valve seat formed in the bodycrosswise to the valve stem opening spaced from the valve-stem opening forming a chamber between the valve-stem opening and the seat, the said channel communicating with the chamber and the inside of the container, a supply connection formed on the end of the body beyond the valve seat, and a stem turnably mounted in the valve-stem opening engaging with the valve seat between the supply connection and the channel.
3. In a valve of the type described a body having one end constructed to fit engagingly on a liquid container and the other end provided with a supply connection, a bore being provided through the body leading into the liquid container, a valve seat formed on the end of the body near the supply connection spaced from the bore thereby forming a chamber between the bore and the valve seat, the said bore having helical grooves, and a channel within the body sidewise from the bore communicating with the chamber and the inside of the liquid container. I
i. In a valve of the type described a body secured to a liquid container projecting off the container, the body having a supply con nection at the farther end, a valve seat formed near the supply end crosswise to the body, helical grooves in the wall of the valvestem opening through the body leading into the liquid container, a float-operated stem turnably mounted in the valve-stem. opening engaging with the valve seat and having means to engage with the helical grooves in the valve-stem opening, and a channel communicating with the inside of the liquidcontainer and the inside of the body when the stem engages with the valve-seat, the channel forming the communication between the inside of the liquid container and the supply connection when the stem is in disengaged position off the valve seat.
