HANDLE FOR STEAM-VALVES.

ISPECIFICATION forming part of Letters Patent No. 548,398, dated October 22, 1895.

Application filed November 27, 1894. Serial No. 530,105. (No model.)

To aZZ whom it may concern:

Be it known that I, VVILLIAM W. SHOE, av citizen of the United States, residing at Nel lingford, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Handles for Steam-Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to handles for steamvalves; and the object of my improvement is to construct a light cheap handle that will always remain cool and can be readily and securely attached to the stem of a steamvalve. I accomplish the desired result by making the handle of one or more thin metal strips, constructed and arranged as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of my improved handle secured on the stem of the steam-valve. Fig. 2 is a plan view of the handle, showing it secured to the valve-stem. Fig. 3 is a view of one of the bent-up strips forming the handle. Fig. 4 is a plan view of a modified form of my improved handle. Fig.5 is a view of one of the bent-up strips having a tapering tubular base, its bent-up ends secured together and a flat ring secured thereon.

A A are metal strips forming the body of the handle. These strips are formed from a sheet-metal blank that is out to the required size and shape and afterward pressed up into the shape shown in Fig. 3.

a. a. are tubular projections, pressed up or otherwise formed integral with the middle portions of the strips A and A. These tubular projections form the base for the handle and extend inwardly, as shown in Fig. 3, fitting snugly one into the other, the under one being provided with a key-seat b.

B is a flat metal ring securing together the ends of the strips A A and thus forming a grip for the hand.

I) b are rivets securing the stripsA to the ring B.

C is the stem of the steam-valve (3.

c isthe key fitting into a slot in the valvestem and into the key-seat in the tubular base a.

Instead of fastening the handle to the valvestem by means of the key 0, driven into the key-seat b, the handle may be fastened by any other convenient means.

I do not desire to be understood as limiting myself to the tubular base a shown and described as it is obvious that this base a may be of any shape desired without departing from the spirit of my invention.

The tubular bases at are preferably formed slightly tapering, as shown in Fig. 5, and if the valve-stem C is formed with a corresponding taper the two parts will fit very tightly together, requiring a very little pressure to hold them on the valve-stem.

By inserting a suitable tool through the central opening in the ring B the key 0 can be driven tightly into place and the handle can be forced down on the stem, so as to fit thereon very securely.

If desired, the free ends of the metal strips A may be extended until they meet or overlap each other and the ring B secured thereon to give the proper stiffness to the handle, or the ring B may be left off entirely if the strips A are made heavy enough and the free ends secured together by a rivet.

Having thus described my invention, what I claim as new, and desire to secure, is-

1. A handle for steam valves composed of thetwo metal strips A, A, bent to shape and the surmounting ring B, joining said strips, A, A, the middle portion of each of the said strips A, A, having therein the upwardly extending tubular bases that fit one into the other, substantially as shown.

2. A handle for steam valves composed of the metal strips A, A, secured one across the other and the fiat ring B, mounted on strips A, A, the middle portion of each of said strips ed to fit upon the end of the valve stem, as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM W. SHOE.
