VALVE.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed December 1, 1911. Serial No. 663,451.

To all 'w71 om t may concern Be it known that we, LOUIS GEORGE KUN- ZER and JOHN HENRY LEWIS, citizens of the United States, and residents of Chicago, in the State of Illinois, have invented certain; new and useful Improvements i in Valves, of which the following YYis a speciication.

Our present invention relates in general to valves, and more particularly to types of valves constructed to be quickly opened, and to require no packing of the stern, and has special referencevto the provision of an improved form of valve combining the quickopening and packless features.

The principalfobjects of our invention are the provision of an improved construction of quick-opening and packless valves which may be opened with Ythe greatest ease, and with a minimum of movement as well as of effort; theprovision of a valve structure thus characterized wherein the valve is Vwell balanced on its seat; the provision of improved arrangements of ground contacting surfaces whereby Vthe use of a stuffing box containing packing or of other packing devices is avoided; the provision of an Vimproved arrangement of ground joint and pressure device for the purpose stated; the provision of an improved form of indicator for showing the positionV of the valve; and generallyY to improve, cheapen and simplify valves of the present character; together with such further objects as may hereinafter appear.4

Structures embodying our present improvements are available for a variety of purposes, but we find them peculiarly adapted for applicationto railway locomotives as blower-valves, where there is considerable demand for them in connection with so-called smoke-consuming arrangements, the manipulation whereof requires a valve which may be Vinstantaneously opened with the least exertion in order to insure the desired use thereof to the end that the results sought may be efficiently attained.

A valve embodying our improvements, as

*will be manifest upon an linspection of the accompanyingv drawing, requires but a very short movement of the handle in orderrto throw it wide open, and actual test shed-ws that under a steam pressure of two hundred pounds per square inch, the valve may be opened with pull of butY six pounds on the operating handle;

In attaining the stated objects as well as certain further benefits and advantages to be below disclosed we have provided a construction of valve illustrated in preferred form in the accompanying drawing, wherein V Figure 1 is a longitudinal sectional View of the valve structure, taken on the line I-I of 2, Figs. 2 and 3 are respectively an end view and an Linder plan view of the valve of Fig. 71; and Fig. Llis a vertical sectional view taken on the line IV-IV of Fig. 1.. V

Y lReferring first more particularly 'to Fig.

it will be noted that in carrying out our invention we employ casing 10, which may be made of cast-iron and preferably provided with vertically disposed inlet and 75 outlet Openings 1l, and 12, suitably threaded internally for the reception of the required pipe connections. For establishing communication between the Openings 11 and 12 upon a short movement of the valve and its operating handie, we form in the wall of the casing 10, openings 13 and 14 (see Fig. 4) communicating y with the openingVVV 12 and with the interior of the casing. Y

IVithin the casing 10 the valve spindle 85 15 is longitudinally disposed, the casing being apertu'red at an end for the reception Vof vthe valve stem 16 and open at the opposite end for the introduction of the spindle andthe valve 1'7 removably carried 90 thereby, whereby replacement ofthe valve when worn or grinding either ofit or of the casing portions contacting therewith may readily be effected. @l

To the end of further aiding in the quick opening of the valve,the valve 17Yis grooved as indicated at 18 (Fig. 4) and cut away as indicated at 19 and 20, whereby the contact of the peripheral portions, 21, 22 of theYY valve Vwith the corresponding surfaces 23,24 and 25 is decreased materially, but not sufficiently to interfere with its efficient operation. .g

For the purpose of making a tight joint without the use of stuffing box constructions orQother packing, the stem 16 is provided with a collar 25 having a conieally ground portion '26 seated in a complementarily ground portion 27 of the casing 10, the ground joint thus attained being a substantially steam-tight joint. The valve 17 is normally held against the collar 25 by means of a boss 28 on the nut 18, which boss is bored as indicated at 29 for the reception of a stud 30 formed on the spindle 15, a spring 31 being interposed between the bottom of the housing thus formed and the end of the spindle, whereby the surfaces 26 and 27 are forced into cont-act and the ground joint thereby formed kept tight.

The stem 16 is provided between its projecting end 32 and the collar 25 with a plurality oic grooves 33 and rings 34 arranged transversely of its axis to aid in maintaining the tightness of thejoint. For the operation of the valve, the stem is provided with a lever handle 35 held in position by a nut 36 engaging a threaded portion 37 of the stem.

As is clearly to be seen on viewing Figs. 1 and 2, the handle 35 is intended to stand perpendicnlarly when the valve is closed, but in order to visibly indicate whether or not the valve is open the casing 10 is provided on its frontal aspect with a legend to-wit: as here shown the word Open as indicated at 88, such legend being normally covered by a ilanged portion 39 provided on the handle, but visible through one of the openings 40' when the handle is moved to open position. 1

For limiting as well the closing as the opening movement of the handle, a pin 41 is inserted in the casing, the projecting portion 42'thereof engaging one of the openings 40 or a groove 48 formed in the handle.

In the operation of a valve embodying our improvements, as will readily be seen on reference to F ig. 4, a short movement of the handle 35 in either direction will cause the one of the valve portions 21 or 22 to uncover one of the corresponding openings 13 or 14, thus quickly establishing connnunication between the openings 11 and 12.

Having thus described our invention and illustrated its use, what we claim as new and desire to secure by Letters Patent is:

1. A valve device comprising, in combination, a casing, a valve rotatably mounted therein, and a handle Jfor rotating the valve, said casing being provided with a legend, said handle being provided with means for covering said legend when in one position, and a plurality of openings one thereof to display said legend when in another position and said casing being provided with means engaging a recess in the handle for limiting the movement of the valve by the handle.
