2 Claims. (Cl. 251-44) This invention appertains to steam traps and more particularly to a novel valve and valve seat therefor.

One of the primary objects of my invention is the provision of a novel reversible valve for a steam trap, whereby when the valve becomes worn the same can be reversed so as to bring a new machine face in operative position relative to the valve seat.

Another importantV object of my invention is the provision of a reversible valve seat for the valve, the seat being of such a construction that the same can be readily removed and reversed relative to the valve so as to bring a. new valve seat in operative position relative to the valve.

A further object of my invention is the provision of novel means for constructing the reversible valve and the valve seat therefor, whereby the valve can be quickly removed from its stem to permit the reversing thereof.

A further object of my invention is the provision of novel means for constructing the valve guide body whereby the yvalve stem will be held in its operative clamping position in engagement with the valve. A further object of my invention is the provision of novel means for associating the valve guide body, the valve seat and associate parts with the body of the trap whereby al1 threaded joints, pins and the like are eliminated so as to permit the easy assemblage of these parts and to also eliminate leakage, any leakage other than through the valve seat being noticeable from the outside of the trap.

A still further object of my invention is to provide a novel valve and valve seat assembly for steam traps of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a rea.- sonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed,.

Figure 3 fs a section taken at right angles to Figure 2 on the line 3--3 of Figure 2.

Figure 4 is a vertical central section through c steam trap of the upright bucket type showing my improved valve and valve seat assembly indf corporated therewith.

Figure 5 is a vertical central section through a steam trap of the float type showing my improved valve and valve seat assembly incorporated therewith, and

Figure 6 is an enlarged detail section through the valve stem and guide taken on the line 6--6 of Figure 2 looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates a steam trap of the inverted/bucket type, and the same embodies a casing. "or housing 10 having the inlet 11 at its lower end. The upper end of the casing or housing 10 is provided with a laterally extending marginal attaching flange 12 to'which is -bolted the casing head 13. The casing head 13 is provided at one side of its axial center with an outlet 14 which can be surrounded by a boss 15. Ar- 80 ranged within the body or casing 10 is the inverted vented bucket 16 which is disposed directly over the inlet 11. This bucket is provided at its upper end with a pivot lug 17 to which is pivoted one end of the valve lever 18, the oppo- S5 site end of the lever being pivotally connected as at 19 to depending pivot ears carried by the casing head 13 at one side of the outlet 14.

In accordance with my invention I provide a valve guide and seat holder 20 which includes a. 90 reduced annular portion 21 for reception within the outlet 14 and forming a snug engagement with the wall thereof. The reduced portion 21 denesa shoulder 22 which seats upon the boss 15. This guide is provided with a central bore 23 and 95 the upper end of the same around said bore is rabbeted to provide a socket 24 for the valve seat 25.

The valve seat 25 can be of annular construction and is machined on its opposite faces so that the same can be readily reversed and as shown the same is provided with the central port 26. The valve seat 25 is removably held in place by the outlet cap 27 which'is internally threaded for the reception of the outlet pipe (not shown). The outlet cap 27 is provided with attaching ears 28 through which extend the anchoring stud bolts 29 carried by the casing cover 13. Suitable nuts 30 are threaded on the stud bolts in engagement with the ears 28 for holding the outlet cap 110 in intimate contact with the valve seat and by this construction it is to be noted that the valve guide, seat` and outlet cap is held in4 place merely by the use of two nuts and that by the removal thereof access can be readily had to the valve seat for permitting the reversing thereof and that the valve guide can be removed, for a purpose, which will be later described.

Slidable within the guide 20 is the valve stem 32 which is of a novel construction and forms one of the salient features of my invention.

The valve stem 32 embodies companion clamping jaw sections 33, the lower ends of which are provided with mating pivot ears 34 through which extends the pivot pin 35. The pivot pin 35 likewise extends through a pivot lug 36 formed on the yoke 37 which straddles the valve lever 18. A pivot pin 38 extends through the yoke 3'7 and the valve lever for rockably connecting the stem therewith. The stem, as shown in Figure 6 of ,the drawing, can be made polygonal shaped in cross section so as to permit the passage of water between the same and the guide 20. The inner faces of 'the clamping jaw sections 33 of the valve stem 32 are recessed as at 39 and the recesses 39 communicate with semi-circular grooves 40 which open out through the upper outer end of the stem. The recesses 39 are semi-conical shaped for a purpose, which will now be described.

I employ a novel valve 41 which includes opposite disposed conical valve bodies 42 connected together by the cylindrical short post 43 and it is obvious that, from Figures 2 and 3 of the drawing, when the sections 33 of the valve stem 32 are spread apart and swung on the pivot pin 35 that the valve 41 can be inserted between the sections 33 with one valve body 42 placed within the recesses 39 and the other valve body extending exteriorly of the stem toward the seat 25. When the sections are swung together the valve is rmly held and due to the engagement of the stem 32 with its guide 20 opening movement of the sections relative to one another will be prevented.

When it is desired to reverse the valve, it is merely necessary to remove the nuts 30 and take off the outlet 27, after which the seat 25 and the guide 20 can be removed from the outlet opening 40 which will allow the swinging open of the sections 33 and the removal of the valve 41 for the reversing thereof. Likewise the seat 25 can now be reversed if necessary.

From the construction, it can be seen that no screw threads or pins are employed and that any leakage will take place in such a way that the same can be readily seen from the outside of the casing.

It is obvious that my improved valve and valve seat assembly can be incorporated with various types of steam traps and in Figure 4 I have shown my improved valve and valve seat assembly incorporated with a'steam trap B which is of the upright bucket type. In this instance the valve stem 32 is pivotally connected with a valve rod 45, which in turn is connected to the valve lever 46. One end of the lever 46 is pivotally connected as at 47 to the depending outlet sleeve 48 which is formed directly on the casing head 49 of the casing 50. The vopposite end of the lever 46 is pivotally connected to a lug 51 connected with the bucket 52. The bucket 52 is in turn pivotally connected as at 53 to the lower end of a supporting lug 54 connected to the casing head 49.v In this form the valve and valve seat assembly are constructed identically the same as the form previously described and the assembly is held in place in the same manner.

In Figure 5 of the drawing I have shown my valve and valve seat assembly connected with a trap C which is of the oat type and .in this instance the valve stem 32 is connected with a valve rod 60, the lower end of which is pivotally connected as at 61 to the valve lever 62. This lever 62 is rockably mounted at a point intermediate its ends on a pivot pin 63 carried by the depending outlet sleeve 64 of the casing head 65. The opposite end of the lever 62 has pivotally connected thereto the float 66 which can be of any desired character. In this instance the valve and valve seat assembly are constructed identically with the form described in Figure 4.

Changes in details may be made Without departing from the spirit or the scope of this invention, butzv What I claim as new is:

1. In a device of the character described, a valve stem including pivoted companion clamping jaw sections and a reversible valve having oppositely disposed duplicate valve body ends, and reduced connecting stud, the companion clamping jaws receiving one of the duplicate valve bodies and connecting stud therebetween.

2. In a valve assembly, a valve guide having a bore, a valve stem slidable in said bore including a pair of pivotally connected companion jaw clamping sections, and a reversible valve including duplicate valve ends, one of which is received between said companion clamping jaws, the engagement of the valve stem with the guide holding the sections in clamping engagement with one another.
