COCK.

SPECIFICATION forming part of Letters Patent N 0. 656,991, dated August 28, 1900.

Application filed April 23, 1900.

T0 aZZ whom it may concern:

Be it known that 1, JOHN MORRISON, a citizen of the United States, and a resident of Dubuque, in the county of Dubuque and State of Iowa, have invented a new and Improved Cook, of which the following is a full, clear, and exact description.

This invention relates to a means for permitting the adjustment of the plugs of stop and waste cocks, so that the plug may be rendered right or left handed in operation, according to the desire of the user or to the position of the cock.

This specification is the disclosure of one form of my invention, while the claim defines the actual scope thereof.

Reference is to be had to the accompanying drawings, formin a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of the invention. Fig. 2 is a plan View with parts in section on the line 2 2 in Fig. 1. Fig. 3 is a plan view of the casing of the cock with the plug and cap removed. Fig. 4 is a bottom plan view of the cap. Fig. 5 is a side View of the top of the casing, and Fig. 6 is a section on the line 6 (5 of Fig. 4:.

The casing a of the cock is of the usual construction, being provided with a waste-outlet a, as will be understood. The plug 1), which works in the casing, may also be of the usual or any desired construction and is formed with the main passage Z1 therein and a wastepassage h all of which parts operate as will be understood. It will be observed that the water-passage b of the plug is considerably nearer the tapered or lower end of the plug 1) than the waste-outlet a of the casing a, but still above the lower end of the main passage 1). XVith this construction the waste-hole of the plug can never by any misadjustment be brought into registry with the waste-hole of the casing and so cause waste from the pres sure side.

The top 0 of the plug may be of any desired cross-sectional form, so that the removablysecured cap d may be caused to turn there with. This cap is formed with a central opening d, conforming to the angular form of the top 0 of the plug, through which open ing the top of the plug passes, the cap rest- Serial No. 13,923. (No model.)

ing on the top portion a of the casing a, so as to turn around the same with the plug. The top a of the casing a is provided on its upper end with two lugs a which are located diametrically opposite each other and are approximately equal in length to about oneeighth of the circumference of the top of the casing. This proportion is, however, unimportant so long as the disposition of the opposite lugs limits the throw of the plug to approximately ninety degrees of a circle. The lugs a bear against the under side of the top of the cap dand against the inner side walls of the peripheral flange of the cap, and the cap is provided with two interior lugs (1 which, as indicated in Fig. i, are situated opposite each other and bear against the edge of the top a of the casing, the lugs a and 61 being in the path of one another, so as to strike when certain movements of the cap and plug are made.

When the cap is in place, one of the lugs (Z lies on each side of the top of the casing, and as the cap is turned the lugs 01 will respectively strike against the lugs a so as to limit the movement of the cap. In this connection it will be observed that when one of the lugs d strikes its corresponding lug a the other lug d will strike its corresponding lug a on the opposite side. This arrangement will therefore limit the movement of the plug and necessitate turning the plug ina certain direction, so as to open or close the same. Therefore by changing the position of the cap on the casing the throw which it is necessary to give to the plug will also be changed, and thus a cock may be made right or left handed, as desired. The plug may be turned by ahandle e of any sort, suitably connected therewith, and in the construction shown this handle is formed separate from the cap 61 and is received in a suitable socket in the plug, the handle and cap being secured by a a single set-screw f, which passes through the top 0 of the plug at a point above the cap (Z and engages the handle, as shown in Fig. 2. The relative arrangement of the cap and handle or other operating devices, however, form no part of my invention, the essentiality of which lies in the relative formation of the cap and its arrangement with the casing,as will be pointed out in the claim. It will be seen in this connection that any two of the lugs taken together constitute ninet degrees of a circle, and consequently that t 'e plug is al- Ways prevented from performing a greater movement. 4 r

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- The combination of the cock-casin g having a passage and provided with projections, with the cap surrounding said projections and arranged to engage the casing with its edge, the caphaving an interior lug adapted to engage the said projections, and an opening-of non-- circular shape, and a plug mounted to turn in the casing and controlling the passage thereof, said plug having a portion passing through the opening of the cap and of the same outline therewith, the plug being securable to the cap in two different positions. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
