Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed. March 1917. Serial No. 156,832.

' which the following is a full, clear, concise,

and exact description, reference beinghad to the accompanying drawings, forming a part of this specification.

My invention relates to control valves, and has for its object the provision of a valve of this character adaptedin its operation to control a plurality of passages successively:

Other objects of the structure will be more clearly apparent from a detailed description of carrying out one form of my invention, which I will now give in connection with the accompanying drawings illustrating the same, in which- Fgure 1 is a side view of my improved valve structure;

Fig. 2 is a side view of the valve structure looking at the opposite side to that of Fig. 1';'

Fig. 3 is a top view of my improved valve structure,

Fig. '4 is a of Fig. 3,

' Fig. 5 is a sectional view on line 55 of Fig. 4 j

"Fig. 6 is a sectlonal view on hne 66 of Fig. 4;

Fig. 7 is a sectional view on line 5-5 of Fig. 4c, the parts being in difierent position from that shown in Fig. 5;

Fig. 8 is a sectional view on sectional View along line 4.1

line 8 8 of Fig. l; and

Fig. 9 is a sectional view on line 66 of Fig. 1, the parts however occupying an alternate position to that shown in Fig. 6.

My improved structure consists of the casing 10 within which is rotatably mounted. the valve proper 11. This valve carries at its upper end a plate 12 from which projects the handle 13. The plate 12 has a plurality of notches 14 with which the lug 15 carried by the spring pressed lever 17 cooperates. engagement with these notches by the spring 16. This lug 15 also cooperates with the stops 1,8 and 19 to limit the movement of the valve. I

In'Fig. 3 the .valve handle 131s shown 1n valve structure is attached.

The lug 15 is'normally held in.

22 carried by the slide rod 23. The slide rod 23 may be slidable on any suitable stationary part of the machine to which the I p This slide rod is controlled sothat the lug. 22 is normally between the lugs 20 and 21 and prevents movement of the valve handle13. As soon as the slide rod is moved inwardly as shown in Fig. 3, to, disaline the lug 22 from the lugs 20'and 21, then the valve handle 13 may be'moved either clockwise or contraclockwise as the case may be.

The valve proper 11 has a control passage 25 which is preferably Y shaped, one branch of which extends clear across said valve from one side to the other. The valve further has the passage way 26 extending clear across, having however at 'one extremity a restricted passage 27. A passage 28 communicates with the passage 26 and extends at rightv angles thereto. The valve furthermore has the large exhaust passage 29 extending clear through. The valve casinglO' has various ports consisting respectively of'the inlet port 30 adapted to supply fluid under pressure, the exhaust port 31, theport 32 leading to a device to which pressure may be supplied, the port 33 leading to another device to which pressure may be supplied, and the exhaust port 34. The port 32 preferably leads to a device to which pressure may be supplied and the port 31 cooperates with that same device as an ex haust port. The port 33 is adapted to lead to a second device to which pressure is tobe supplied, and the cooperating exhaust port therefor is the port 34. The port 30 is designed to permit the supply of pressure to the valve structure for distribution in ac cordance with the above. 7 v The normal position of the device is shown in Figs. 1, 2, 3 and 7. Under these conditions it will beseen that the passageway 29 permits exhaust from the port 33 through the port 3l. It will also be seen that by means of the passageways 28 and 26, the port 32is connected with the'exhaust p rt 251. The port 30 under these conditions is entirely closed oil as neither passageway .26 nor 25 con'nnunicates therewith. Now when the handle 13 moved into the firs torwa rd position, which is shown in Fig. a, then fluid under pressure is supplied by means ot the passage ay 26 troin the inlet port Ell through the port to one of the devices to be operated therehv. Jnder 'tllH condition of things the port is still exhaicnng by way of the passageway 29 through the port The second :t'orward position, which is also the last, is shown in Fig. (1. wherein passageway 26 still connects 1 ie inlet port 30 with the port 3:2 to maintain the pressure on the device conne ted therewith, but at the me time passageway connects the i ct port 30 with the port 33 leading to the :-:econd device controlled by the valve.

it will thus be seen that the first move ment ol the handle supplies pressure to one device and the second movement supplies pressure to a second device, the first device still remaining supplied with fluid under pressure. During the reverse movement of the handle 13, of course, the positions occupied are the same as those outlined for the forward movement. Should the handle 13 be moved contra-clockwise from its neutral position into its only reverse position, then the various passageways occupy the position shown in Fig. 9. Under this condition of things the port 33 is not connected with an exhaust passage, but fluid under pressure supplied through the passageway 25 from port- 30 to the port 33, thus to operate but one of the instnunentalities instead of the two first outlined. The inward portions of these ports 30 and flare so that the passage may communicate therewith when placed in alinenient. The passages 30 and extend toward the passage as shown in Fig. i so that said passage may intersect said ports and accomplish the proper c0nncctions.

It will thus be seen that by properly arranging the various port passages in the valve casing and eltecting a corresponding structure of the valve 11 that two pressure operated devices may be successively controlled at one time, whereas but one need be operated with another position of the valve.

From the foregoing which illustrates merely one of the uses to which my invention may be put its general nature will be apparent to those skilled in the art, and having thus described one form which my in venlion may take, what I claim as new and desire to secure by Letters Patent is:

l. A valve structure of the character described comprising a valve casing and a valve therein, said alve casing having a pressure inlet port, an exhaust port and two outlet: ports, and said valve having passageways whereby said pressure inlet port may be connected to said outlet ports successively and then remain in connection with both said outlet ports when said valve is moved in one direction, and said pressure inlet port may be connected with only one of said out let ports when the valve is moved in the opposite direction.
