REVERSIBLE INDEX FOR COCKS.

Patented Jan. 19, 1909.

Serial No. 3&0,106.

To all whom it may concern:

Be it known that I, ANTON O. SCHUERMANN, a resident of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Reversible Indexes for Cocks, of which the following is a specification.

The object of this invention is to provide the handles of valve stems of cocks with reversible index, or indicator, buttons and to incorporate the buttons in the handles as a part of the necessary structure thereof.

The present invention is an improvement over U. S. Patent No. 857957 which covered a fixed cock body, an index button mounted thereon for rotary adjustment, and indications on its upper face at opposite sides of its center. Not only do I mount the button 011 a rotary or oscillatory part of the cock by means peculiar to this invention, but I provide indications on both its faces so that it may be inverted or reversed and I make the button seat so large as to efiectively conceal whatever indication may exist on the lower face. These ideas are exemplified in the structure hereinafter described and defined in the appended claims.

In the drawings forming part of this specification Figure 1 is a side elevation of a basin cock provided with my improved index handle. Fig. 2 is a plan of the under surface of a handle adapted for use with an index button in accordance with my invention. Fig. 3 is a plan of the upper surface of my combined handle and button. Fig. 4 is anentral vertical section through the button and handle, showing the relation of the same to the valve stem. Fig. 5 is an edge view of the button in its preferred form.

A rotary valve stem is shown at 1 and at 2, in Fig. 4, is shown a squared end of the valve stem which acts as a seat for the handle 3. The handle may be of any general shape consistent with pro er turning of the valve stem and it has pecu iarities as follows :A boss, or collar, 5 projects downward from the center of the handle and it has a square Socket 5 as shown in Fig. 2, which conforms to the squared end 2 of the valve stem 1. The upper surface of the handle is concaved concentric with the axis of socket 5 and the concavity is shaped to form the seat 4 for the index button 6.

The button is shown herein as and is by preference made convexo-convex so that either flattened face is better adapted to rest against the seat 4, and it is centrally bored through its shortest diameter to admit the screw 7. It is provided with suitable designations such as Hot and Cold, which may be placed on one face but on diametrically opposite sides of the axis, or on opposite faces of the button (2'. a, top and bottom), or on both opposite sides and opposite faces as shown in Fig. 5.

The squaring of the end of the valve stem leaves shoulders against which the boss 5 of the handle bears, the squared end of the handle terminates below the button while tial edge of seat 4 whichas seen in Fig. 4 is preferably of greater concavity than the convexity of the button, and the screw 7 extends through the button and into the end of the valve stem while its head 7 bears against the central part of the upper face of the button. Pressure of the screw head against the central part of the button presses the under face of the button firmly against the circumferential seat 4 and is thence transmitted through the handle to the shoulders of the stem. Consequently the screw and the button act to secure the handle firmly on the stem and the handle and the screw clamp the button securely against rotary displacement.

The central location and small size of the screw head permit complete and convenient exposure of the designating characters, leaving them presented in positions to be most easily read under ordinary manipulation of ceals all designating characters on the lower face of the button.

The button may be shifted by loosening lthe screw and turning the button around 1 with the screw for an axis, or the screw may be withdrawn, the button shown in Fig. 5 i turned upside down and adjusted properly and the screw be replaced and tightened.

The button is an operative element in securing the handle on the stem or other rotary or oscillatory part of .a cock, and it is also of utility in ena ling a cock to be used for a plurality of purposes. The improvement .15 particularly applicable to right-andthe button is sustained by the circumferenthe handle, and the larger size of the seat conright nor left, as cross-handle compression cocks for instance, but it may have some utility in other environments and I do not restrict its use to any particular kind of cock.

By the use of my im rovement the necessity for carrying in stock a selection of special cocks for each separate use is largely obviated.

When the cock is used for hot water the word Hot is exposed, or presented in a conspicuous position, and when the cock is used for cold water the word Gold is made conspicuous. If both words are on the same face of the button this is done by adjusting it so that the proper word shall stand toward the user when the valve stem or movable member is in its normal position (i. e. before it has been turned); but if the words occur on opposite faces as in my preferred form, the button is reversed or inverted, and possibly also set axially, to expose the proper one and conceal the other. If the cock should be applied to other uses the button would be provided with words or characters indicating such uses and the operation would be'the same as hereinbefore described.

While it is preferable that the end 2 of the valve stem shall be square in cross section, it is obvious that any non-circular form, or form that will prevent a corresponding handle socket from turning thereon, will meet the purpose of my improvement. So, throughout the specification and claims the term square, when applied to the valve stem and handle socket, is used in the sense of non-circular.

The squared end of the valve stem is bored axially and internally screw-threaded to receive the screw 7.

I claim,-

1.
