HUGH C. WALFORD, OF BERLIN, ONTARIO, CANADA.
LIGHTNING-ARRESTER.
To all whom it may concern:
Be it known that I, HUGH G. WALFORD, of the town of Berlin, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Lightning-Arresters, of which the following is a specification.
My invention relates to lightning arr-esters of the type in which a metal block connected to earth is separated by small air gaps from blocks to which the line wires are connected. Such arresters, while eifective, usually leave the system with which they are employed out of order after the passage of the disruptive discharge due to lightning owing to the fusing together of the blocks and the consequent grounding of the line.
It is my object to overcome this difficulty and I accomplish my purpose by supporting a plurality of independent arresters in such a manner that on the passage of a disruptive discharge the arrester in use at the time of the discharge is moved out automatically and another arrester moved into its place.
Figure 1 is a side elevation of my improved arrester. Fig. 2 is a plan view of the same. Fig. 3 is a sectional detail of an individual pair of arresters with their common ground.
In the drawings like letters of reference indicate corresponding parts in the different figures.
A B are the line wires connected to the binding posts 0 D respectively. These posts are electrically connected with the spring contact arms E F.
A metal disk G is mounted to rotate between the contact arms E F, being secured to a metal spindle H revolving in the metal standards I. These standards have bases J which are connected to binding posts K which are connected by the Wire L. The metal disk G has disks of fiber a or other insulating material secured to opposite sides thereof, and to these fiber disks are connected a series of radial spring arms 6 which are adapted to clamp the individual arresters M against the metal disk (at. These individual arresters are of a common type comprising two pairs of blocks 0 (Z, having an air gap formed between them. The inner blocks are in electrical contact with the disk G. The backs of the outer blocks a are grooved to receive the spring arms I). If either of the binding posts K be connected Specification of Letters Patent.

Serial No. 464,120.
to earth and a pair of arresters is between the contact arms E F as shown in the draw ings, a disruptive discharge entering either of the binding posts 0 D will pass through one of the contact arms E F leap the air gap in the individual arrester in contact with the said contact arm, pass through the disk Gr, through the spindle H, one of the standards I and thence to earth. The passage of the disruptive discharge, however, will fuse together the parts of the arrester through which it has passed, and I therefore provide means conditioned to operate by the passage of the discharge for rotating the disk and bringing a fresh pair of arresters into position between the contact arms E F. For this purpose I provide means tending to rotate the disk, preferably a spiral spring N connected at one end to the spindle H and at the other to some stationary part. By rotating the disk G the spring may be wound. A step-wise movement of the disk is permitted by an escapement O which engages the shoulders formed on the periphery of the disk G. This escapement is suitably pivoted on a stationary part, preferably the frame f, supporting an electromagnet P. This magnet is provided with a pivoted armature which is provided with a shoulder 71, adapted to engage the projection i to retain the escapement O in the position shown in the drawings.
A coil spring secured to the escapement and the frame f tends to rock the escapement to release one of the shoulders 6, but this movement is normally prevented by the engagement of the shoulder 71, with. the projection i. If the electro-magnet be energized the armature will be rocked and the escapement allowed to rock to permit of the escape of one shoulder e and the engagement of the next shoulder c as the disk G is rotated by the spring N. A coil spring we normally holds the annature away from the magnet.
The electromagnet is energized as follows :One of the binding posts K is con nected by a wire Q with the binding post I form in the connection an air gap T. This is preferably formed by dividing the wire Q and connecting the divided ends to two metal plates Z between which the air gap is formed. This gap may be filled with carbon granules to reduce resistance. From this arrangement it follows that every time a disruptive discharge enters the line wires A or B and passes through either one of a pair of arresters to the ground that the disk G will be caused by the discharge of said current to rotate and bring a fresh pair of individual arresters into position for use.
