Description

Patented June 13, 1933 UNITED STE JOHN G. KENNEDY, OF ELMIRA, NEVI" YORK, ASSIGNOR' TO THE KENNEDY VALVE MFG.
(#0., 015 ELIVIIRA, NEVI YORK, A. CORPORATION. OF NEW YORK VALVE Application filed December 4,1930. Serial No. 500,102.
This invention relates to certain new and useful iinprovemen s in valves and more particularly to means ror attaching the handleor wheel to the valve stem, the object being to provide a valve stem with a plurality of straight flutes and the hub of the wheel with a plurality of straight flutes which are adapted to interlock with the flutes of the valve stem when the same are forced together so 1 as to form a positive connection between the valve stem and valve, the same being held in interlocked position by a nut mounted on the threaded portion of the valve stem.
Another object of my invention is to provide the stem and the here of the hub with flutes which are substantially V-shaped in cross section, the bore oi the handle being straight and the stem tapered; so that when the two are forced together, a wedging action is obtained between the tapering V- shaped face on the stem and t 10 straight on the wheel or hand e of the interlocking flutes.
A still further object of the invention is to provide a valve with a handle and stem which can be readily connected and disconnected and one which can be manufactured very cheaply.
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.
In the drawing,
Figure 1 is a side elevation of a portion of a valve casing showing a wheel constituting the handle secured in position on the valve stem in accordance with my invention;
Figure 2 is an enlarged vertical section showing the wheel and handle in interlocked position; 7
Figure 3 is a transverse section through. the wheel showing the straight flutes on the interior of the bore of tie wheel;
Figure l is a section taken on'line i of Figure2; I
Figure 5 is a detail section, partly in ele vation showing straight ii-shaped flutes in the hub of the wheel and on the stem; and
Figure 6 is a section taken on line 66 of Figure 5.
In the drawing 1 indicates a valve casing which may be of the conventional form, 2 a valve stem and 3 the wheel or handle. The upper end of the valve stem 2 ispro'vided with a tapering portion having tapering sub stantially V-shapcd flutes l, the flutes being radially arranged parallel with the central axis of the stem.
The wheel or handle 3 is provided with a straight bore 5 having substantially ii-shaped.
straightlflutos 6, the flutes being arranged parallel with the central axis of the wheel so that when the handle is forced in position on the stem, the straight flutes of the bore of the wheel will pass between the tapering flutes on the tapering portion of the stem, whereby a wedging action is obtained so as to securely lock-the handle in position on the stem.
The end of the stem is reduced and threaded as shown at 7 and on which is adapted to work a hexagonal nut 8 for locking the handle and stem together whereby the two members can be forced together in such a manner that all lost 'motion is prevented and an exceedingly tightcoupling is formed between the valve and valve wheel or handle.
In the modification shown in Figure 5, 9 indicates a valve stem which is provided with V-shaped flutes 10 adjacent its end between which are adapted to extend the V-shaped flutes 11 formed on the interior of the hub 12 of a hand wheel 13, said stem being re duced at 14 on which is mounted a hexagonal nut 15 for locking the V-shaped flutes of the handle between the Vshaped flutes of the stem so as to form a rigid connection between the two. 7
In Figure 1 to 4 I haveshown an improved method of attaching handles to valve stems in which the valve stem adjacent its free end is provided with a tapered truncated cone portion having radially arranged tapering flutes which are substantially V-shaped in cross section and are adapted to cooperate with straight flutes formed on the bore of a hub of a wheel, the tapering flutes being par allel with the central axis of the stem and the straight flutes with the hub of the handle, whereby I provide a method of attaching a handle to a valve stem in such a manner that his when the two are forced together, a wedging action is obtained so as to form a rigid connection between the valve stem and handle whereby the wear caused by the removal and insertion of the handle can be taken care of, as by operating the nut on the valve stem any wear will be compensated for by the movement of the inclined "face of the stem and the straight face of the Wheel or handle.
In both forms I connect the handle to the valve stem by providing the handle and valve stem with V-shaped flutes which interlock with each other and are secured in interlocked position by a nut working on the re duced threaded end of the valve stem.
What I claim is:
1. In a valve, a valve stem having a tapering portion adjacent its free end provided with tapering flutes substantially V-shaped in cross section, the free end or said valve stem being reduced and threaded, a wheel having a cylindrical bore ot the same diameter throughout its length provided with straight flutes substantially V-shaped in cross section, the flutes being arranged parallel with the central axis of the bore and a nut working on the threaded end of said valve stem for forcing the straight flutes of the wheel between the tapering flutes of the valve stem and for locking said valve stem and wheel together.
2. A valve having a valve stem provided with a tapering portion adjacent its free end and a threaded portion at its free end, the tapering portion of said valve stem being provided with tapering flutes, a hand wheel having a cylindrical bore of the same diameter throughout its length adapted to extend over the taperin portion of said stern, said bore having straight flutes adapted to interlock with the tapering flutes oi": the stein the tapering portions of the flutes of the stem being arranged to interlock with the straight flutes oi the bore of the wheel and a nut work ing on the threaded end of said stem engaging said wheel for forcing the straight flutes ot the wheel and the tapering flutes of the stem in frictional engagement with each other.
3. As a new article of manufacture, a valve having a stem provided with a tapering portion said tapering portion being provided with tapering flutes having longitudinally converging side walls, a handle or wheel having a bore of the same diameter throughout its length provided with straight flutes having longitudinally disposed parallel side walls adapted to interlock with the tapering flutes oi the stem, and a nut mounted on said stein for locking said handle or wheel in position on said stem.
In testimony whereof I hereunto affix my signature.
JOHN G, KENNEDY.
