ILLUMINATED ELECTROMAGNETIC VALVE KEEPER TOOL gwuonkw strewn/x 7 Patented July 18, 1950 UNITED STATES PATENT OFFICE ILLUMINATED ELECTROMAGNETIC VALVE KEEPER TOOL J amcs D. Carr, Harvey, Ill. Application November 5, 1946, Serial No. 707,944

This invention relates to a valve spring keeper tool for placing the keepers on the valve stem of the valves when making the insertion of the valves within the engine. I

' It is an object of the present invention to provide a tool whereby the effort required for the placing of a split valve spring keeper upon the valve stem will be kept to a minimum and may be effected Within little time.

It is another object of the present invention to provide a valve keeper tool which is of simple construction, easy to manufacture, and which is efficient in operation.

It is an another object of the present invention to provide in a valve spring keeper tool a positive device for retaining the valve spring keeper which comprises a magnet and a lamp in circuit relation with the magnet whereby the location to which the valve spring keeper is to be placed may be observed.

It is another object of the present invention to provide a valve spring keeper tool wherein both of the keepers, which are of the split type, can be simultaneously retained by the tool while being located into their proper positions upon the valve stem.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a plan view of a valve spring keeper tool of a type adapted to retain both of the keepers simultaneously and resembling a pair of pliers.

Figure 2 is a side elevational view of the keeper tool shown in Figure 1.

Figure 3 is a cross sectiona1 view taken on line 33 of Figure 1 and looking in the direction of the arrows thereof and showing an enlargement of the portion of the tool where the pivotal parts are connected together and where the lamp adapted to direct rays of light upon the location where the keepers are to be placed, is maintained.

Figure 4 is an elevational view with portions broken away in the area of the lamp of a modified form of tool adapted for retaining one keeper at a time.

Figure 5 is a plan view with portions broken away to show certain of the parts within the tool.

Figure 6 is a wiring diagram of the lamp and magnet circuit.

Referring now to the Figures 1 to 3, I0 represent one form of the tool which is of the type resembling that of a pair of pliers and which includes a part or arm H and a part or arm l2 hinged together by a pivot pin l3. These parts face of the keeper.

- into place over the keepers.

1 Claim. (01. 240 6.46)

have forward extensions M with magnets I5 thereon and keeper engaging portions or curved ends [6 extending forwardly from the magnets and curved as indicated at I! to grip the curved On each of the parts H and I2 is a handle portion [8 adapted to be retained together by a spring l9. I6 is accordingly the pole of the magnets which holds the keeper while the electromagnet I5 is energized.

On the top of the parts I I and 12 adjacent their connection together by the pivot pin I3 is a shield 2| adapted to keep a lamp 22 from shining in the operators eyes while he is putting the keepers on the valve stem. The operator is accordingly freed of the necessity of having to hold a separate flashlight while he is working. On the part I2 is a switch 23 connected by a wire 24 with the magnet IS on one of the parts and from the magnet a wire 25 extends to the lamp 22 and from there to a magnet l5 by way of wire 26. The return wire from the magnet 15 is indicated at 21. A wire 28 extends into the part 12 for connection with the button 23. Any convenient source of supply as shown in Figure 6 at 29 may be used for effecting the energization of the magnets and the lamp. The wires leading from the ends 01' the handle portion Hi can be connected with the car battery.

When the tool has been connected to the battery of the car and the switch has been set to connect the electromagnets and the lamp with the battery, the light comes on and the electromagnets become energized or magnetized and then if the keeper is placed on the pole of the magnet or magnets they will stay there as long as the current is permitted to flow to the electromagnets. When the keeper is in place against the valve stem the flow of current is stopped by moving the switch with the thumb and the magnets become demagnetized and the tool can be removed leaving the keepers on the valve stem. A small amount of heavy grease placed upon the valve stem will keep or help hold the keeper in place while the valve spring is released and let down Thereafter the spring will retain the keepers in place.

Referring now particularly to Figures 4, or 5 wherein there is shown a tool which will retain at one time only one of the split valve keepers. The tool may be used twice to locate the keepers in place. This tool will not require the space that the other tool requires and thus may be used in places where it is more difiicult to locate the keepers upon the valve stem.

This tool is shown generally at 3| and includes a handle 32, a casing member 33, an electromag net 34 having a pole piece 35 to which the keeper becomes attached when the magnet 34 is energized. Upon the casing 33 is a lamp 36 and a shield 31 enclosing the lamp to prevent the light rays from passing rearwardly to interfere with the operators eyes. In rear of the shield 31 is a press button-38. Wires 39 and 40extend into the rear of the handle for connection with the electromagnet 34 and the lamp 36 in the manner as illustrated diagrammatically in Figure 6. The core of the magnet 34 has a threaded projection 42 adapted to connect the same with the casing 33.

The casing 33 surrounds a core portion 43 to which the various parts are connected. Wires 4.4 and v 45 may be retained against displacement by a bolt 46 in the core part 43. The casing 33 retained on the core part by fastening screws ll.v

Having now described my invention, I claim: In a valve keeper tool having a pair of handle members pivotally connected together near one members for securing the valve keepers thereon, 25

a light bulb socket, member fixed on said tool 4 closely adjacent the pivot of said handles, a forwardly-directed reflector fixed on said tool above said pivot and said light bulb socket, and circuitconnecting means including a switch operatively connecting said light bulb socket and said electromagnets in series with a supply circuit.
