March 24, 1964 T. s. HALLETT SPINNER HANDLE FOR VALVE WHEELS AND THE LIKE Filed NOV. 15. 1961 United States Patent 3,125,899 SPINNER HANDLE FOR VALVE WHEELS AND THE LIKE Thomas S. Hallett, Sub. P.(). 28, Calgary, Alberta, Canada Filed Nov. 13, 1961, Ser. No. 151,946 1 Claim. (Cl. 74-557) My invention relates to new and useful improvements in spinning handles for valve wheels and the like.

It is well known, particularly in the oil industry, that various valve wheels have to be rotated in order to open and close certain valves. The valve wheels have to be rotated many times in order to obtain the necessary movement of the valves controlled thereby and this is an onerous task particularly when several valves have to be operated.

By providing a spinning handle for the valve wheels, I have overcome this disadvantage.

Although spinning handles have been in use, never theless the main difficulty with such spinning handles is the securement thereof to the valve wheel rims, inasmuch as said valve wheel rims are normally made of a relatively hard steel. It is therefore difiicult to obtain a firm attachment unless the valve wheel rims are drilled and a pin is passed through the spinning handle body and the rim.

However this is an undesirable practice inasmuch as it weakens the rims and also due to the hardness of the steel, it becomes an extremely difiicult operation,

By providing a spinning handle which is clampable around the rim and which is provided with case hardened serrations adapted to bite into the surface of the rim, I have overcome the principal disadvantages of conventional spinning handles.

The principal object and essence of my invention is therefore to provide a device of the character herewithin described which can readily be positioned upon the rim of a valve wheel and can be tightened thereon to eliminate slippage.

A further object of my invention is to provide a device of the character herewithin described which not only includes serrations on the top and bottom plates but also serrations on the lower end of the handle holding bolt which can therefore be tightened down so that it bites into the surface of the rim and makes a firm anchorage for the spinning handle.

Another object of my invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture, and otherwise well suited to the purpose for which it is designed.

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

FIGURE 1 is a sectional elevation of my device, sectioned in part to show the interior thereof.

FIGURE 2 is an underside plan view along the line 2-2 of FIGURE 1.

FIGURE 3 is a top plan view along the line 3-3 of FIGURE 1.

FIGURE 4 is a fragmentary cross sectional elevation on an enlarged scale substantially along the line 44 of FIGURE 2.

In the drawings like characters of reference indicate corresponding parts in the different figures.

Proceeding therefore to describe my invention in detail, reference should be made to the accompanying drawings in which reference character indicates, in phantom, the rim of a valve wheel.

My invention includes a clamp collectively designated ICC 11 consisting of a bottom plate 12 and a top plate 13. Both of these plates are hexagonal when viewed in plan and the inner surfaces 14 thereof are provided with a plurality of concentrically located serrations 15 edge sharpened and case hardened in order to facilitate the engagement thereof with the aforementioned rim 10.

Bolts 16 pass through the top and bottom plates, nuts 17 clamping the plates to the rim 10.

The top plate 13 is apertured centrally as at 18 and is provided with an upstanding shoulder portion 19 surrounding the aperture 18. The aperture 18 and the shoulder 19 are internally screw threaded and adapted to receive a bolt 20 which extends through the shoulder 19 and the aperture 13 so that the lower end 21 of the bolt can engage the surface of the rim 111.

This lower end 21 is also provided with concentrically located serrations 22, edge sharpened and case hardened, which facilitate the gripping of the rim by the device.

In this connection a nut portion 23 is formed upon the bolt intermediate the ends thereof and this nut portion facilitates the tightening of the bolt upon the rim It) in order to force the serrations 22 to bite into the surface thereof.

An upward extension 24 of the bolt 20 is provided above the nut 23 and this extension is provided with an annular groove 25 adjacent the outer end 26 thereof.

A spinning handle 27 is provided with a shoulder 28 which is apertured and adapted to fit over the extension 24 of the bolt, screw threaded pin 29 extending through an aperture in the shoulder 28 so that the inner end 30 of the pin seats within the annular groove 25. This prevents disengagement of the spinning handle 27, yet at the same time allows free rotation thereof upon the aforementioned bolt extension 24.

Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claim without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

What I claim as my invention is:

A spinning attachment for hand-manipulated wheels, said attachment comprising in combination a pair of spaced apart clamping plates adapted to receive awheel rim therebetween, a pair of clamping bolts extending through said plates, said plates having opposing surfaces each provided with a plurality of concentric serrations for securely gripping the stated wheel rim when said bolts are tightened, a post provided on and projecting outwardly from one of said plates in coaxial relation to said concentric serrations, and a handle rotatably mounted on said post, said one of said plates being provided with a screwthreaded aperture concentric with said serrations, said post having a screw-threaded inner end portion disposed in said aperture, and the inner end surface of the post being formed with a set of concentric serrations for securely gripping the stated wheel rim when said post is tightened in said aperture.
