UNITED STATES I PATENT OFFIC JOHN H. BENNETT, OF WORCESTER, MASSACHUSETTS.
VALVE FOR OIL-HOLES.
SPECIFICATION forming part of Letters Patent No. 678,931, dated July 23, 1901.
Application filed December 19, 1898. Serial No. 699,659- (No model.)
To all whmn it may concern.-
Be it known that 1, JOHN H. BENNETT, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Valves for Oil- Holes, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents in central sectional view a journal-bearing of a shaft containing one of my improved oil-hole valves inserted in journal-boxes. Fig. 2 is a central vertical sectional view of my improved oil-hole valve. Fig. 3 is a top view of the cup-shaped diaphragm by which the orifice for the admission of oil is closed.
Similar letters refer to similar parts in the different figures.
The object of my present invention is to provide a simple and efficient valve for oilholes which can be cheaply constructed and is capable of hermetically closing the oil-hole and providing an ample passage-way for oil when the valve is opened, and I accomplish these results by means of the oil-hole valve as hereinafter described, and set forth in the annexed claims.
Referring to the drawings, A denotes a portion of a revolving shaft; B, the boxin which the shaft is journaled, provided with an oilhole 0, which communicates with the journal-bearing of the shaft A and is closed by means of my improved oil-hole valve, which consists of a cylindrical shell or case D, fitting the hole 0 and provided at its outer end with a flange D, which rests upon the outer surface of the box B. The cylindrical shell or case-D is also provided at its upper end with the internal flange D having a central circular hole or opening E, which is closed by the inserted cup-shaped diaphragm F. The diaphragm F is stamped or drawn from a piece of sheet metal by suitable dies into a cup shape, having vertical sides F and a bottom F curved in the form of a spherical arc. The diameter of the cup-shaped diaphragm F is greater than the circular hole or opening E and less than the diameter of the shell D, and its curved bottom F is normally held in contact with the circular edge of the opening E by means of the spiral spring G, having one end pressing against the cup-shaped diaphragm F and its opposite end pressing against a narrow internal flange H at the lower or opposite end of the shell D. Projecting from the edge of the cup-shaped diaphragm F are prongs I, which are bent downwardly and parallel with the axis of the shell D. Each of the prongs projects radially from the edge of the cup-shaped diaphragm F far enough to bring the straight section of the prong against the inner surface of the shell D, thereby serving to hold the cup-shaped diaphragm F concentrically with the circular opening E.
The valve is opened by pressing the cupshaped diaphragm F down against the tension of the spiral spring G, allowing oil to enter the annular space between the diaphragm F and the cylindrical shell D and flow between the prongs I to the journal-bearing. As soon as pressure is Withdrawn from the diaphragm F the valve is automatically closed by the action of the spiral spring G, which carries the spherical surface F into the openingE and in contact with the edge of the interior flange F The top of the diaphragm F is slightly depressed in the center, forming a recess F to receive the tip of an oil-can or other instrument, by which pressure is applied to depress the diaphragm, the recess F serving to hold the tip of the oil-can concentrically with the curved top of the diaphragm.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The combination with a shell or case with a passage therethrough for the flow of oil, a cup-shaped diaphragm by which said passage isclosed, said diaphragm having prongs projecting radially therefrom and bent parallel with and brought into contact with the sides of said ease, whereby the diaphragm is held concentrically with said shell or case and at right angles with the sides,and a spring applied to said diaphragm, substantially as described.
2.v An oil-hole valve consisting of a shell or case adapted to be removably held in the oilhole of a journal-bearing, said shell or case the thrust of a spring and at its opposite end an internal flange provided with an opening to said shell or case, a cup-shaped diaphragm the internal flange D a springG bearing against said cup-shaped diaphragm and the internal flange H, and prongs I projecting from the edge of said diaphragm andbent downwardly in contact with the sides of said shell or case and outside said spring, substantially as described.
- Dated this 13th day of December, 1898. JOHN H. BENNETT. Witnesses:
