- Another object is to provide an improved indicating device for a cock, which is not easily removed without damaging the device beyond a reusable condition.
- Still another object is to provide an improved indicating device for a cock, which may be inexpensively manufactured and which permits an improved cock design.
- FIG. 1 is an elevational view of a portion of a cock and an indicating device embodying the invention
- FIG. 2 is a side elevational view of the structure shown in FIG. 1;
- FIG. 3 is an enlarged sectional view taken generally on the line 3-3 of FIG. 1;
- FIG. 4 is a sectional view taken on the line 44 of FIG. 3;
- FIG. 5 is an elevational view of an indicating device embodying the invention.
- FIG. 6 is a plan view of a retaining ring of the indicating device shown in FIG. 5;
- FIG. 7 is an elevational View of another form of the indicating device.
- an indicating device embodying the invention comprises a button member having a substantially flat or slightly curved surface, the button member being adapted to be disposed in a cavity formed in a cock with the surface facing outwardly. Symbols or markings may be made on the surface to indicate the function of a particular cock.
- a plurality of outwardly extendings fingers are fastened to the button member, which are wedged in the cavity when the device is installed and hold the button member in the cavity. The fingers are constructed such that they would be damaged beyond a reusable condition if the device were removed, thereby preventing a prankster from removing the indicating device from one cock and installing it on another.
- FIGS. 1 and 2 illustrate a portion of a cock of the type commonly used in chemistry laboratories, which includes a body 11), a bonnet 11 secured to the body 10, a stem or spindle 12 which extends through an opening formed in the bonnet 11 and into the body to actuate a valve mechanism, and a handwheel or knob 13 secured to the end of the stem 12.
- the handwheel 13 may be secured to the stem 12 by a screw 14.
- FIGS. 2 and 3 which extends through an opening formed in the handwheel 13 and is threaded into an axially extending hole formed in the end of the stem 12.
- the head 15 of the screw 14 holds the handwheel against the stem 12 and flutes or splines (not shown) may be provided to prevent relative rotation of these two members.
- the foregoing described cock is one for which an indicating device of the present invention is suitable but the invention is not limted to a cock of this particular construction.
- a cavity, indicated generally by the number 18, is formed in the handwheel 13 at approximately its center, and an indicating device, indicated generally by the numeral 19, is fastened in this cavity 18.
- the indicating device 19, as best illustrated in FIGS. 3, 4 and 5, includes a button member 211 and a retaining ring 21.
- the button member 20 is preferably made of a durable somewhat flexible material such as nylon, and includes a dish-shaped disc portion 22 and a generally cylindrical portion 23 on the concave side of the portion 22. These two portions are preferably formed integrally.
- the cylindrical portion 23 is formed with four axially extending slots 24 which define four arcuate sections 25.
- An annular groove 27 is formed in the outer surface of the cylindrical portion 23 substantially midway between the dish-shaped portion 22 and the end of the cylindrical portion, and the outer surface of the cylindrical portion is tapered as indicated at 28 between the groove 27 and the end.
- the side of the groove 27 away from the tapered surface 28 forms a shoulder 29 the outer diameter of which is greater than the maximum diameter of the tapered surface 28.
- the retaining ring 21 includes an annular portion 30 and a plurality of radially extending fingers 31, FIG. 6. At the point, indicated generally by the numeral 32, Where each finger 31 joins the annular portion 30 the ring is bent such that the fingers 31 are inclined relative to the plane of the annular portion 30 as shown in FIGS. 3 and 5.
- the retaining ring 21 is installed on the button member 20 by positioning the opening in the annular portion 30 of the ring 21 around the end of the cylindrical portion 23 with the fingers 31 inclined toward the dish-shaped portion 22, and forcing the retaining ring 21 toward the dishshaped portion 22.
- the slots 24 formed in the cylindrical portion 23 permit the arcuate sections 25 to bend inwardly as the retaining ring 21 slides over the tapered surface 28. After the retaining ring 21 reaches the annular groove 27 the inward force on the sections 25 is released and they spring outwardly to their normal positions. The sides of the groove 27, which form shoulders, then prevent the ring from being pulled off the button member.
- the button member 20 could also be constructed with the taper 28 eliminated and the diameter of the portion between the groove 27 and the inner end slightly less than the inner diameter of the ring 21.
- the ring could then be installed on the button member by sliding the ring over this portion until it meets the shoulder 29, heating this portion until it is pliable, and then deforming this portion to cause it to bulge outwardly around the inner side of the ring, thereby forming a groove having an inner shoulder that holds the ring on the button member.
- the axial slots 24 defining the arcuate sections 25 may be eliminated if desired.
- the button member is positioned with its convex outer surface 33 facing away from the cock and is pressed into the cavity 18 until the end of the cylindrical portion 23 reaches the bottom of the cavity. In this position the outer surface 33 bulges outwardly from the surface of the handwheel, as shown in FIG. 3.
- the outer diameter of the fingers 31 of the retaining ring before insertion is slightly greater than the inner diameter of the cavity 18, so that the fingers flex toward the open end of the cavity as the button and ring are pressed into the cavity.
- the shoulder 29 forms a seat for the ring as the button and ring are inserted.
- the inner shoulder of the annular groove 27 would bear against the annular portion 30 of the ring 21 and prevent the button member from being pulled away from the ring.
- the ends of the fingers 31 would bite into the side of the cavity and the forces on the ring would permanently deform the fingers 31 beyond a reusable condition. Therefore the indicating device could not be removed from one cock and reinstalled on another, thereby preventing prankstcrs from interchanging them and possibly causing injury.
- FIG. 7 shows an alternative construction of the indicating device. It comprises a button member 35, which may be similar to the button member shown in FIGS. 3 to 5, and a plurality of fingers 36 constituting end portions of a plurality of strips 34 preferably made of metal.
- the strips 34 extend through a cylindrical portion 37 of the button member 35, and both fingers of each strip are bent toward a disc portion 38 of the button member, similar to the fingers 31 shown in FIG. 6.
- the strip 34 may be installed on the button member 35 by molding the button member around them. It is apparent that with this construction the taper 28, slots 24 and groove 27 of the previous embodiment are not required.
- the installation on a cock and the operation of the indicating device of FIG. 7 is similar to that described for the indicating device of FIGS. 3 to 6.
- the outer convex surface 33 of the button member 20 or the button member 35 may be provided with any desired symbol or marking to indicate the function of the cock to which it is attached.
- the button member is provided with the letters H.W. to indicate hot water.
- the button members may be provided in a variety of colors to further indicate various types of cocks.
- the indicating device described has numerous advantages. It is inexpensively manufactured and easily installed but, as previously described, it is not easily removed and reinstalled on another cock.
- the indicating device has another very important advantage in that it eliminates the necessity for the threaded retaining rings heretofore necessary, thereby allowing a more modern and smoother cock design.
