D is a partition placed inside of the casmg and extending from the bottom part thereof upwardly to near the top. The partition D is attached by means of soldering or otherwise to the base which in the device of Fig. l is D and has an exteriorly threaded portion adapted to engage with the threads D formed in the lower part of the casing A, and inthe device shown in Fig. 6 the base is al and is provided with interior threads which engage with the threads d formed on an upwardly projecting part of the casing A. The partition 1) divides the lower part of the interior ofthe To all whom it may concern:

Be it known that I, J OHN H. KINEALY, a citizen of the United States, residing at Ferguson, in the county of St. Louis and the State of Missouri, have invented a new and useful Improvement in Valve Devices, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to valve devices for from radiators or heaters of heating systems, and relates more particularly to that type of such devices in which the flow of air and water through the device is controlled by the temperature existing in the device in such a way that as long as the temperature in the device is less than a certain predetermined amount, air or water or both may flow through the device, but when the temperature in the device has been raised to a certain predetermined point then the flow of air or water or both through the device will be substantially stopped and the only flow through the device will be that due to leakage.

The object of my invention is to provide a thermostatic trap or valve device for the discharge of air and water of condensation from radiators or heaters of heating systems that will not be likely to get out of order; that will be simple in its construction and mode of operation; and that will not depend for its operation upon the expansion of a solid or of any form of bellows inclosing a volatile liquid.

My invention is fully shown in the accompanying drawings where similar letters are used to designate similar parts.

Figure 1 is a vertical section of one embodiment of my invention; Fig. 2. is a sectional view of Fig. 1 along the line 2-2; Fig. 3 is a sectional view of Fig. 1 along the line 3-3; Fig. l is a top view of a part of the device shown in Fig. 1; Fig. 5 is a plan view of a second embodiment of my invention having a part of the cover or top removed; and Fig. 6 is a vertical sectional view of the form of device shown in Fig. 5.

Referring to the figures, A is a casing having an inlet B and an outlet C. The device is attached to the radiator or heater by means of the inlet B and is attached to a suitable discharge pipe by means of the outlet C.

the purpose of identification may be called the primary well and the secondary well, respectively.

G- is an inlet passage connecting the inlet B with the primary well E.

In the device shown in Fig. 1 the top of the primary well E lies some distance above the top of the inlet B so that water or air entering the inlet well must pass upwardly from the inlet through the inlet while in the form of device shown 1n Fig. 6 the upper part of the primary well E lies below the upper part of the inlet B so that water or air may flow directly from the inlet into the primary well E without being lifted. The secondary well F is connected to the outlet C by means of an outlet passage, which in the device shown in Fig. 1 is made up of the vertical passage through the hollow tube H in the top of the casing of the device, and the passage 1-1,, leading from the passage H to the outlet C. In the form of the device shown in Fig. 6, the outlet passage connecting the secondary well F to the outlet C is formed of the passage 7L through the upper part of the base piece 61 the passage or space k inside of the base piece al an the passage k connecting the space h with the outlet C.

I is a valve piece adapted to control the outlet passage and attached to a stem J. In the form of the device shown in Fig. 1, the stem J is a tube which encircles the tube H and which has at its lower end immediately above the valve piece I a plurality of openings J through which water and air may pass from the well F into the space between the lower end of the tube H and the valve piece In the form of the device shown in Fig. 6, the stem J is a rod which casing A into two wells E and F, which for v passage G;

the passage H formed the yoke K which in turn is attached to the inverted ring shaped bucket P. In Fig. 1 the stem J is shown as soldered to the yoke K, while in Fig. 6 the stem J is shown attached to the yoke K by means oflock-nuts K, and K,. The yoke K may be soldered or otherwise suitably fastened to the bucket P.

vL is a threaded cap which engages with threads out in the upper part of the casing A and serves to prevent the passage of air and water from the interior of the casing in any way except through the discharge passage. This cap L is provided with a raised part L by which it maybe grasped by a wrench or other suitable instrument and screwed into place. In the form of device shown in Figs. 5 and 6, the cap is Z, and it is provided with a raised part Z, adapted to be grasped by a wrench or other suitable instrument and screwed into place.

In theform of the device shown in Fig. l, M. is a cover plate which rests on the, upper part of the casing A outside of the cap L in such a way as to form a space between the outside of'the cap L and the-inside of the cover plate M. This cover plate M is held in position by means of the nut N which engages with the upwardly projecting nipple N formed on the upper part of the cap L. The portion L of the cap L is provided with transversely arranged grooves L which connect with the interior of the tube I-I so that water or ,air which passes upward through the tube H may pass through the grooves L into the space between the cap L and the cover M. It is understood that the grooves L and the spacebetween the cap L and the cover plate M constitute the part H of the discharge passage. The part N, of the cap L is preferably provided with a vertical opening N so that when desired the nut N may be removed and access may be had to the interior of the tube H through the passage N The inverted bucket P sets in the primary well E and is therefore shaped to conform to the shape of this well, and in the form of the device shown in the drawings this primary well E is of a circular shape with the secondary well F also of a circular shape formed inside thereof, so that a top view of the bucket P is ring shaped as shown in Figs. 2 and 5. The vertical walls ofthis bucket are preferably parallel as shown in the drawings, although this is not necessary.

Q represents volume tubes of an inverted siphon or U-shape, whereby communication is made between the interior and exterior of the bucket P. When water flows into the primary well E. in the device shown in Fig.

1, the water will rise inside of the well and also inside of the bucket P, and as the water rises inside ofthe-bucket Pthe air will pass out from the bucket through the U-tubes Q until the water has reached the upper open ends of the short legs of the tubes Q, and then the water will pass down into the short 'legs and accumulate in the bends attthe lower part of the tubes and thus by preventing the escape of air from the bucket will prevent the water from rising inside of the bucket P much if any beyond the top of the open short legs of the U-tubes Q, even although the primary well E or the whole device should become completely filled with water. In the form of the device shown in Fig. 6, when .water enters the primary well E it will accumulate therein and the water will rise inside and outside of the bucket P, the air escaping from the bucket through the tubes Q as the water rises, until the water has risen outside of the bucket to the open upper ends of the short legs of the tubes Q, and then the water will enter the tubes Q and accumulate in the lower ends thereof and seal them so as to prevent the escape of air from inside of the bucket and thus prevent the water from accumulating inside of the bucket to a point materially above the bottom of the opening of the short legs of the tubes Q, even although the primary well E or the whole device should become filled with water. The U-shaped volume tubes Q must be so adjusted that the amount of air confined or trapped in the upper part of the bucket 'P- I by the accumulation of water in the pri- 100 mary well E shall be insufficient to make the bucket float, even when the bucket'is entirely submerged by the accumulation of water in the primary well, unless the air in the upper part of the bucket shall be heated to a certain predeterm ned temperature after it has been confined or trapped in the bucket. That is to say, the air trapped in the upper part of the bucket P must be in suflicient, to make the bucket float even when 11 submerged so long as that air is'cool, but when the air after it has been trapped is heated to a predetermined temperature and thus made to expand it will increase the buoyancy of the bucket so that the bucket 115 will tend to float and will move upwardly inthe primary well E. When the air in the bucket P expands, the bends in the inverted siphons or U-tubes Q prevent these tubes from becoming unsealed and thus prevent 120 the air from'being forced out of the bucket as it is heated. The formof device shown in'Figsl to 4 inclusive is provided with a by-p'ass passage G, which communicates with the lower end. of the discharge passage through the opening G which is controlled by means of the valve G Sediment will accumulatein the passage G and when desired it may be blown out by opening the valve G v The Operation of the device is as follows: The device is attached to a radiator or heater and to a suitable discharge pipe so that when steam is turned on to the radiator the air will pass from the radiator through the inlet B and the inlet passage G into the space above the secondary well F, and thence through the secondary well F and the discharge passage into the outlet C, and from there into the discharge pipe and away. As the radiator gets warm because of the admission of steam thereto, water will be condensed and this water will pass through the inlet 13 and the inlet passage G into the primary well E where it will accumulate. In the form of the device shown in Figs. 1,2,3 and hthe pressure at the outlet C must be less than the pressure at the inlet 13, in order that water may be forced upward through the inlet passage G into the primary well E, but no such differential pressure is necessary with the form of the device shown in Figs. 5 and 6. After the water has accumulated .in the primary well E to the top of the partition D the water will overflow into the secondary well F. From the secondary well the water will pass through the dischargepassage to the outlet C and thence into the discharge pipe. hen water first begins to accumulate in the device it will be comparatively cool, but as the radiator gets hot and as all the air becomes discharged therefrom steam will pass from the radiator into the device and the water which passes from the radiator will be hot, so that because of the steam and the hot water the device will be heated. As the temperature inside the device increases the air confined or trapped in the bucket P is heated and is made to expand, and when this air has been heated to a certain predetermined temperature it will. have been made to expand a sufficient amount to cause the bucket to tend to float and to rise in the primary well E. WVhen the bucket rises it will lift the yoke K and with it the stem J and the valve piece I, and thus close the discharge passage and prevent the discharge of steam or water through the device. After the discharge passage has been closed water will continue to accumulate in the device until the air inside of the bucket P has become cooled so that its buoyancy is no longer sufficient to make the bucket float, and then the bucket will fall and the valve piece I will be moved downward so as to open the discharge passage and allow water to be discharged from the device. As soon as hot water or steam in sufficient quantities begins to come to the device the air in the bucket will again be heated and be made to expand, and the bucket will be made to rise so as to lift the valve piece I and close the discharge passage and thus prevent the discharge of steam through the device. In this way the expansion and contraction of the air in the bucket will be made to operate the bucket so as to move the valve piece I to control the discharge passage.

.It is evident that the height of the top of the partition D must be such that the water will rise to a level in the primary well, before passing into the secondary well, such that the bucket P may float when the air in the bucket is heated sufficiently.

The casing may be of any shape and the inlet may be placed with respect to the outlet so as to require a differential pressure to make the water from the radiator pass through the device as in the device shown in Figs. 1, i 3 and a, or the device may be made so that the outlet is at a lower level than the inlet and water will flow therethrough by gravity as in the device shown in Figs. and 6; and it is also evident that the device may be made of any size desired.

The device has no parts that are likely to break or get out of order, and there is no solid body upon whose expansion the operation of the device depends, nor is there any bellows inclosing a volatile fluid which. is likely to leak and thus become inoperative.

In the drawings a pluralitv of inverted siphons or U-shaped tubes Q are shown, although this is not necessary. It is preferable, however, to have a plurality of such tubes in order to insure that there will always be a passage for the air from the interior to the exterior of the bucket when water is accumulating in the primary well in order to fill. it, and thus insure that the volume of air confined or trapped in the upper part of the bucket will always be the same. The form of U-tube shown in Fig. 1 in which the long leg projects upwardly through the top of the bucket is preferable to the form shown in Fig. 6 since the former is not so likely to become stopped, and since it also tends to equalize the pressure of the air inside and outsideof the bucket better than does the form shown in Fig. 6.
