ALBERT GA'BEL, 0F MUSCATINE, IOWA.

LIGHTNING-ABBESTER.

To all whom it may concern:

Be it known that I, ALBERT GABEL, a citizen of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented new and useful Improvements in Lightning-Arresters, of which the following is a specification.

This invention relates to improvements in lightning arresters and the principal object of the invention is to provide means for preventing injury to telegraph and telephone instruments by lightning.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of the invention;

Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is a section on line 33 of Fig. 1.

In these views 1 indicates a drum having its ends threaded to receive the end members 2. The drum and end members are preferably made of copper and said end members are provided with the reduced tubular end portions 3 provided with the slots for receiving the ends of the wires 4. The ends of the wires after passing through the slots are then wound around the end pieces, as shown. 5 is a substantially U-shaped strap made of insulating material having its ends bent nd secured to the drum as at 6. The cross piece of said strap is provided with an opening through which a rod 7 passes. The rod is screw threaded to receive a pair of nuts 8 which are located on each side of the cross piece of the strap so as to adjustably support the rod by the strap. A hollow ball or sphere 9, preferably made of copper, is held on the upper end of the rod and said ball may be secured to the rod by being screwed thereon or brazed thereto. The lower end of the rod is provided with flattened part and with a groove and opening to receive the Specification of Letters Patent.

Application filed April 15, 1919. Serial No. 290,134.

ground wire 10, said wire being wound about the rod.

My device may be placed at any desired point in the circuit with the ball placed any desired distance from the drum. It will thus be seen that the current passing along the drum will jump to the ball 9 so as not to damage the telephone or telegraph instruments.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a drum, circuit wires connected therewith, a rod, insulated means for supporting the rod from the drum, a hollow ball carried by the rod adjacent the drum and means for grounding said rod.

2. A device of the class described comprising a drum, circuit wires connected therewith, a support carried by the drum and made of insulated material, a, rod adjustably carried by said support, a ball at the upper end of the rod and means for grounding said rod.

3. A device of the class described comprising a drum, circuit wires connected therewith, a support carried by the drum and made of insulated material, a rod adjustably carried by said support, a hollow ball carried by the upper end of the rod and means for grounding said rod.

4. A device of the class described comprising a drum having screw threaded ends, end members screwed to said ends and provided with tubular slot portions, circuit wires, engaging said slotted portion, a bracket carried by said drum and made of insulated material, a rod adjustably supported in said bracket, a hollow ball carried by the upper end of said rod and a ground wire connected with the lower end of said rod.

In testimony whereof I afiix my signature.

ALBERT GA'BEL.
