VALVE TOOL.

CHARLES DINES SEVIER AND FRANK PETER ECKROAT, 013 FORT COLLINS, COLORADO VALVE TOOL.
Specification of Letters Patent.
Patented July 18. 1922.
T 0 all whom it may concern:
Be it known that We, CHARLES DINES Suvrun and FR NK PETER ECKROAT, citizens of the United States, and residents of Fort Collins, in the county of Larimer and State of Colorado, have invented certain new and useful Improvements in Valve Tools, of which the following is a specification.
Our invention is an improvement in valve tools. An important object of our invention is to provide a valve tool which will effectively remove the inner valve stem from the valve casing when the lugs on the valve stem have been broken off and when the valve stem has been broken off below the plug.
A further object of our invention is to provide a device as above named which will be inexpensive to manufacture and simple of construction.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a sectional view of the tire valve showing the tool applied in one of its uses,
Fig. 2 is a view partly in section showing the tool in another position in the valve casing, and
Fig. 3 is a perspective view of the device embodying our present invention.
In the (,lrawings 1 designates the valve casing which is screw-threaded on its upper end as at 2. The casing is screw-threaded internally to receive the plug 3 on the valve stem 4. The plug 3 is provided with lugs 5 and 6.
The above is a brief description of the upper portion of the ordinary tire valve.
The device comprising our present invention is shown in Fig, 3, in which 7 represents the main body portion of the tool. One end of the tool is slotted longitudinally as shown at 8 forming the resilient fingers 9 and 10. The opposite end of the tool is screwthreaded as at 11, the threads being left-hand threads and of extreme high pitch in order to produce a firm grip on the plug 3 when this end of the tool is inserted therein and turned.
The grip 12 provides a finger grip for turning the tool and is either welded or pressed on the body portion 7.
In use the operation is as follows:
If the lugs 5 and 6 have been broken ofl the top of plug 3 as may occur through attempting to seat the same too snugly in the valve casing, making it impossible to remove the plug with the ordinary valve tool, the resilient fingers 9 and 10 of the tool are inserted in the end of the valve casing 1 until the fingers rest upon the top of the lug 3 with the valve stem 4 between the ngers. By exerting firm pressure on the fingers with pliers P or the like, and giving several quick movements to the right and left, the valve stem may be severed near the bottom of the plug. The other end of the tool is now employed to extract the plug 3. This is done by simply inserting the threaded end 11 into the plug and turning the same to the left. When the threads firmly grip the inner walls of the plug 3 said plug will move to the left and will be finally ejected from the valve casing. The grip 12 serves as a finger grip to turn the body of the tool.
This to be understood that various changes may be made in the size and shape of our invention without departing from the spirit of the invention or the scope of the subjoined claim.
We claim:
In a valve tool, a cylindrical body, one end of said body being tapered and screwthreaded on the tapered portion, the other end being bifurcated to form resilient fingers, and a gri mounted on the body, as and for the purposes set forth.
