This invention relates to a plug type valve and particularly a valve in which there is a vertical adjustment of the plug on rotation of a single control handle or wheel used for the rotation of the plug.

An object of my invention is to provide a novel plug type valve in which rotation of the control wheel or handle will rotate the valve to either open or closed position and will also move the valve vertically to seat or unseat the plug in the body of the valve.

A feature of my invention is to provide a novel plug type valve of the character stated in. which rotation of the control wheel or handle will rotate the plug to open or closed position and will also move the plug vertically to seat or unseat the same.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoineddetailed description and the appended claims.

In the drawing- Figure 1 is a partial longitudinal sectional view of my valve.

Figure 2 is a fragmentary sectional view taken on line 2--2 of Figure 1.

Figure 3 is a fragmentary sectional view taken on line 33 of Figure 1.

Figure 4 is a side elevation of the wheel shaft.

Figure 5 is a plan view of the collar.

Figure 6 is a plan view of the bonnet.

Referring more particularly to the drawing, the numeral I indicates a valve body which has intake and outlet ports 2-3 therein. A ported plug 4 is rotatably mounted in the body I and this plug includes a spindle 5 which rises vertically therefrom and projects upwardly through the body I. The spindle 5 is suitably packed or sealed by means of the packing 5, all of which is usual and well known in the art.

A bonnet 'I is mounted on the body I, preferably by suitable bolts or studs, and a cap 8 is threadedcn to the bonnet. A collar 9 is rotatably mounted in the bonnet I. The collar 9 is attached to the spindle 5 by means of the pin II,

and the collar 9 and causing the collar 9 to be moved vertically when the threads I 5 are screwed into or out of the threads I2. A thrust bearing I5 is arranged between the cap 8 and a shoulder I5b on the shaft I 3, thus preventing the shaft I3 from moving vertically relative to the cap, for purpose to be subsequently described. A ring I 5a is positioned between the cap 8 and the top of the bonnet 1. This ring projects under the bearing I5 to hold this bearing in position in the cap 8..

A dog IE is rockably mounted in the collar 9, and this dog is provided with a spur I1, which is moved into engagement with the notch I 8 in the face of the shaft I3. The dog I I3 rocks on a bearing I9 and is provided with two Wings 20 and 2I. The wing 20 bears against an arcuate cut in the upper face of the collar 9, this out being concentric with the bearing I9. The wing 2| projects into a notch 22 in the top rim of the bonnet I. The dotted line position of the dog IS in Figure 2 shows the position of the dog when engaging and dis-engaging the notch I8 of the wheel shaft I3. A spacer ring 23 is positioned on top of the collar 9 and this spacer ring engages the bottom of the bearing I5 when the collar 9 moves upwardly, thus acting as a stop for the collar.

Operation Assuming first that the plug 4 is in open position, that is, fluid is flowing through the ports 2-3:

As observed in Figure 2, the shaft I3 is now turned clockwise by means of the handle III. The spur I! of the dog It is positioned within the notch l3 and, consequently, rotation of the shaft I3 will also rotate the collar 9, the spindle 5, and the plug 4. The wing 2| is also riding on the annular wall 24 on the top of the bonnet 'I, thus holding the spur into the notch I8, while the spindle I3 is dragging the collar 9 and causing the plug 4 to rotate. Notice also that the thrust is on the wing 20, this wing bearing against the recess in the collar 9, as shown in Figure 2.

When the plug 4 is in closed position, the wing 2"I will engage the stop 25 and further rotation of the spindle I3 will swing the spur I! out of the notch I8 and causing the dog It to move into the dotted line position, shown in Figure 2. The shaft I3 is now free to continue rotation without moving the plug 4, and this. continued rotation will cause the threads I5 to screw into the threads I2, thus pressing the plug 4 downwardly into its seat. The valve is now closed and seated. To open the valve the handle I4 is turned counterclockwise and the first part of the rotation of the spindle l3 turns the threads [5 in the threads l2, thus lifting the plug 4 off of its seat and also pulling the collar 9 upwardly until the top of the collar presses against the spacer ring 23. At this time, the collar 9 will also bottom on the threads [5, and this locking is sufficient to cause the col.- lar 9 to rotate with the spindle l3, and the spindle is so timed that the notch I8 is in position to receive the dog ll.

Observing Figure 2, it will be seen that the wing 21 is now engaging the edge 26 of the notch 22, and continued movement of the collar 9 will swing the dog I6 inwardly until the spur I1 is again within the notch [8. The thrust is then conveyed from the spindle 13 through the dog Hi to the bearing I9, thus turning the collar 9 counterclockwise and moving the plug 4 to the open position.
