IIHIIII INVENTORS;

UNIT D STATES PATENT OF IC JOHN HAWTHORN, OF NEW MILLS, COUNTY OF CHESTER, AND SIDNEY MOORHOUSE, OF STALYBRIDGE, COUNTY OF LANOASTER, ENGLAND.

STOP-VA LVE.

SPECIFICATION forming part of Ilett'ers Patent No. 382,469, dated May 8, 1888. Application filel February 7, 1888. Serial No. 263,230. (No model.) Patenteddn England February 11, 1B86,No. 1,984.

[C 1886,) of which the following is a specification. I

Our invention relates to valves for controlling and arresting the flow of fluids, and will be most clearly understood from the following description of the annexed drawing.

: The said drawing is a vertical section of the improved valve.

The shell on is constructed in the usual man-- ner and of a form suitable to the use for which the valve is intended. The bonnet or closingplugb is formed with a packed gland,c, through which passes a screwed spindle, (I, provided at its outer-end with a hand-wheel, e, or other means of turning. The screw-spindle 02 works in the screwed bore of the plug 1). Thelower 2 end of the spindle d is connected to a sliding piston,f, in such a manner that the spindle may revolve without rotating the piston. In the example the foot of the spindle is formed with collars d d. recessed to admit the foot of the spindle, and the lower collar, d and stops or pins g 9 prevent the spindle from being drawn out of the 'piston. The piston is formed of two parts,f andf. A central stud extends from the part fthrough the part f, and is provided with a not, so that the packing h, which is placed between the two halves of the piston, can be C0l1lpressed to'any desired extent.

In the case of high-pressure steam-valves the packing h is preferably of asbestus; but any suitable packing material might be used. The piston accurately fits aseating bored to receive it in the partition ioflhe shell a, or in alining fitted into the partition. The neck a of the shell is bored to receive a sliding cylindrical shield, k, the lowerpart ofithe interior of the shield being bored to fit the piston f f. A ledge, k, is formed in the interior of the shield,

The top of the piston f is and upon the said ledge bears the lower end of a coiled spring, Z. The spring I is compressed between the lower end of the cover-'plug'b and the ledge is, so that the constant tendencyof the spring is to force the shield down upon the seating of the piston-valve. When the piston is within the seating, as shown in the drawing, passage of fluid through the valve is cut off.

To open a passage through the valve, the spindle d is, turned so as to withdraw the piston from the seating. When so withdrawn, the piston first passes into the shield 70,. which remains in contact with the seating. In its upward progress, and when well within the shield,

the piston comes into contact withthe aforesaid inner ledge, k, and overpowers the pressure of the'spring, so as to lift the shield-with it. By this time the piston or the packed portion of the piston has passed entirely into the shield, so that the packing is protected'by the shield from the injurious effects of the rush of fluid through the valve. 1

When it is desired to close the valve, the spindle is turned in the contrary direction un-' til the shield bears on the seating, the continued rotation of the spindle pushing the piston into the seating and arresting the flow through the valve.

We claim as our inventiou-- 1. The combination of valve casing, scat, screw-spindlaand packed pistons operatedtby the spindle, with a shield for the pistons, and 8 a spring acting'on the shield to tend to press it onto the seat, substantially as described.

' 2. The combination of a valvecasing, seat, spindle, and piston,with a shield normally on the seat about the piston and bored to receive the piston as the latter is raised, and elevates the shield also toopen the passage, as and for the purpose set forth.

'In testimony whereof we have signed our names to this specification in thepresenCQ 0f two subscribingwitnesses.
