DISTANT-OPERATED VALVE.

Application filed August 4, 1922. Serial No. 579,634.

To all whom it may concern:

Be it known that we, JOHN M. Entrants, J12, and Brennan F. Fisonnincitizens of the United States, residing at Dayton, in the county of Montgomery. and State of Ohio, have invented certain new and useful 1mproveinents in Distant-Operated Valves, of which the following is a specification.

This inventionrelates to distantly operated valves and more particularly to means whereby a. valve may be operated from a distance.

It is an object of this invention to provide means for operating a valve from a reasonable distance. It is a further object to provide in conjunction with the operating means. a means for protecting the outlet of the valve in an off position, so constructed that the outlet of the valve will be free in an on position. It is further desired to so design a valve operating means that it will be cheap and simple in construction, strong, durable and efficientin operation.

Further objects will become apparent from the following description and drawing, in which:

Figure 1 is a side elevation of the valve and operating mechanism therefor, showing the valvein an off position,

Figure 2 is a view similar to Figure 1 showing the valve in an on position,

Figure 3 is a developed plan of the clamping means forming a portion of the universal joint,

Figure l is an end iew of the clamp as assembled, taken on line 14 of Figure 2,

Figure 5 is an exploded view of one form of the universal pin and rod coupling, and

Figure 6 is a modified form of pin therefor.

Referring more particularly to drawing. 2 represents a valve of the pet-cock type having a wing stem 4: and an outlet 6. To the stem 4 is clamped a rod 8 which leads to within, the reach of the operator. The body 10 of the clamp which is composed of sheet steel having a certain amount of springiness, is punched out as at 12 to form a circular opening 14, is formed with tal 16 and 18 arranged at an angle to a longitudinal center line to the body of the clamping member itself, and itis bent into a substantial U shape. Prior to forming the body portionlO into a. U shape acentral portion on'either side of the Opening 14: is depressed,

as at lei --14: in the same direction so that when the two sides of the body form the U. a substantially spherical space is providlnl therebetween. as will be noted. The tabs 16 and 18 are adapted to be bent over to en gage the edges of the wing stem 4 on the side nearest the valve while the sides of the body 10 are spaced wide enough apart to admit positioning the clamp overthe stem 4. Awinged nut and bolt 26, respective 1;, may constitute the means whereby the sides of the clamp are brought together to Fecurely engage the valve stein.

The extension rod 8 may be of steel or wrought iron and at the valve end thereof is bent to form a circular eye 2 L which passes around and is securely but non-integrally fastened about a short pin 26. The rod 8 passes through the aperture 1-1 and when connected to the pin 26, with the body portion 10 bent around as shown in Figure 2 and said body portion having the depressions 1 1, 1-1", a universal joint is constituted. It will be apparent therefore that we have devised a novel and cheap method of making a universal joint. In the modification shown in Fig. 6 the eye 24 is formed slightly less in diameter than the diameter of the pin 30, which pin has an encompassing depression 26 in order that when the pin is pushed into the eye it will be securely held. The portions 16, 16 are flared out in arcuate shape and the pin 26 is made of such length that a clearance therehetween is provided which will allow arcuate movement of the pin but will prevent its displacement should the pin slip out of the eye of the rod 8. Portions 1? may be bent down along dotted lines 15" in order to avoid rough edges.

To one side of the stern clamp is secured, in a suitable manner, the projection which may he termed a tongue. which tongue projects over, adjacent and close to the outlet 6 of the valve. The tongue 28 is shown covering the outlet in Fig. .1 whereas it is shown swung away from the outlet in Fig. 2.

In manufacturing the device it may be preferable to primarily stamp out the form as shown in Fig. 3 from sheet steel and then stamp out by a second operation the portions along dotted lines 16 or a single stamping operation with a single die may complete such work.

In operation, the rod 8 provided with any convenient turning means, such as a handwheel (not shown) rwill' be rotated, Which movement Will be imparted to the stem clamp 10 regardless of Whether the longitudinalaxes of the clamp and rod 8 are in alignment or not. This movement yvill be imparted thronghthe universal joint as will be obvious.

"We claim r i. A universal joint comprising a U-shaped body member having a hole through the center its c' irvcd portion and hemispherical depressions onopp'osite sides of said hole, a rod having an eye projectingthrough said hole, said eye fitting into said depressions, and a pin positioned betiveen the sides of said body HlOll'lbGl and extending through the eye of the rod. 7

2. A valye-operating device 'coi'iiprising' a U-i'or nedbody having at it's ends opposing tabs for clamping a Valve stein head, and at itsbase two hemispherical depressions therein, and an aperture therethrough, means for securin the clamp to the Valve stein head,

a pin loosely inounted between said depressions, and a rod extending through said aperture and connected to said pin.

3. A combination Valve stein clamp and universal joint comprising a sheet metal bodybent in the. forn of a U said body having a hole at the center 01 the bend and hemispherical depressions formed on opposite sides of said hole and adjacent said hole, tabs at the ends of said body adapted to clamp '21 valve stem head, a fastening means, a rod having an eye passing through said hole, said eye adapted to, fit into and have universal niove'li'ient iii said depressions, and a pin positioned between the sides of the body and extending tliro'ugh said eye.

4:. A valve operating device including a member for clamping a valve stem head, a pin movable in certain directions carried by said member, and an operating hie-ans connected to said pin. a a

In testimony whereof We aflix our signa tures.
