STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 618,503, dated January 31, 1899.

Application filed January 20, 1898. Serial No. 667,199. (No model.)

To all whom it may concern:

Be it known that we, ISAAC N. GLAUBER and JOSEPH H. GLAUBER, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Stop and Vaste Cocks; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention'relates to stop and waste cocks; and the object of the invention is to provide a stop and waste cock in the construction of which provision is made for venting the waste in and through the cock itself and in which the said vent is so located in respect to the waste-outlet that the cock can be set vertically or horizontally and vent equally well in both positions.

Hitherto stop and waste cocks have been made dependent on other means than those within the cocks themselves-for wasting or exhausting the pipes, and in order that the waste or exhaust might really take place it has been necessary, first, to open the faucets or other outlets, so as to vent the pipes and then wait until the pipes were exhausted and close them again, so as to be ready for use the next morning. Obviously to do this in a large building like some of our large factories, where there are many floors and many pipes with long distances to drain through small holes, has been no slight inconvenience and waste of time, so that any convenient and reliable device or construction which will save such extra labor and time and do the work equally well is much to be desired and is a decided improvement in the art.

Referring now to the accompanying drawings, Figure l is a central sectional elevation of one form of our improved stop-cock with the casing or barrel set vertically and with the'plug entering from the side. Fig. 2 is a cross-section thereof on line 2 2, Fig. 1. Fig.

3 is an elevation, partly in section, of the same construction of cock as in Figs. 1 and 2, but with the casing set horizontally and the plug entering from the top, Fig. 4 is'a side elevation, partly in section, of a modification of the invention; and Fig. 5 is an elevation of still another modification, all as hereinafter fully described. These latter views both show the cock in horizontal position, like Fig. 3, but they may also be as seen in Fig. 1.

Having reference first to Figs. 1, 2, and 3, A represents the casing, and B the plug. The plug or valve B has the usual throughwater passage 2 and waste or exhaust orifice or opening 3 at right angles thereto, and the casing has an orifice or passage 4 in position to waste from the central passage2 when the plugis turned around for this purpose, as seen in Figs. 1, 2, and 3. All these parts and features are, however, old and well known and constitute the waste-cock in common use.

Now in order to utilize this old construction for our purpose and produce a'cock which is self-venting and requires no help or attention whatever, as formerly, we cast or drill an air or vent passage 5 through the casing and form a channel 6 in the plug in such position and relation to the waste orifice 4 that whether the casing be placed vertically or horizontally the said vent-passage will be above or on a higher plane than said waste-' orifice, thereby insuring a free and certain discharge of the water from above. We have found that a relatively small difference in respective elevations will answer every purpose and that then an inward suction is created through the vent-passage 5 instead of water flowing out at this point and the water from above courses out through the wasteorifice in astream until fully exhausted with as much safety as it formerly did when the faucets were opened to promote the operation. 4

The channel 6 is comparatively short in the close bearing portion of the plug, so that it does not interfere with the tightness of the plug to prevent leakage, and yet has-such depth from the outer surface of the casing that when the plug is turned to open the way through passage 2 there can be no back leakage through the passage 5. Of course the channel or groove 6 is in such position as to register with the passage 5 when the wastefor use; but it is apparent that the foregoing construction is susceptible of various modifications without departing from the spirit of the invention, the idea in any case being to have a vent in the cock in such relation to its waste that whether the cock be located vertically or horizontallyavent will be opened in and through the body of the cock when the waste is opened and closed when the waste is closed. Fig. 4 presents such a modification, in which the casing or body 0 has the usual plug D and a vent-passage 7 with a self-acting valve 8, adapted to move back and forth within slight but sufficient limits to afford needed relief. Any equivalent and operative valve mechanism might be substituted for the one shown. Obviously if this cock were placed vertically, as in Fig. 1. the vent would be well above the outlet. Normally the valve 8 is seated and is open only when venting, as shown. The waste is through orifice a, central passage 1) in the plug, and orifice c in the casing, corresponding to like passages and orifices 2, 3, and 4 in Figs. 1 and 2.

In Fig. 5 the casing orbody E has the usual plug F and waste-orifice d, and a vent-passage g is provided with a plug or valve h, adapted to be cont-rolled by hand. This vent is located relatively about the same as in the other views, and any suitable hand-operating means may be employed to open and close the vent-passage. Still other forms or modifications of the invention might be suggested, but these are thought sufficient to show the latitude of the invention and the many differentforms it may assume and yet remain within the legitimate scope thereof.

The same principle of construction and use may be applied to whatis known as a compression-stop and waste-valve mechanism or, indeed, to any equivalent construction of valve mechanism wherein the vent may be found desirable.

What we claim is 1. In waste mechanism for Water-pipes, the body and the valve therein having a wastepassage, and a vent-passage in the said body so located as to be above the waste-outlet whether the body be set vertically or horizonrally, and having its inner end opening into the waste-water space, substantially as described.

2. A waste-cock constructed to be interchangeable for vertical and horizontal positions, and having a vent-passage so located as to have the inlet end thereof higher than the waste-outlet in either and both positions of the cock, substantially as described.

3. A waste-cock constructed to be used both vertically and horizontally as occasion requires, and having a vent-passage with its inner end higher than the inner end of the waste-outlet in both positions, substantially as described.

Witness our hands to the foregoing specification this 11th day of January, 1898.
