Wires, of which the following is a full, clear,

and exact description.

This invention contemplates the production of adevice by which overhead wires, es-

pecially insulated feed-wires, may be given a coat of paint or other protective'coating to prolong-their life and preserve them from the elements of the weather.

The invention which I have conceived for performin :this important function is designed to be operated from the ground and apply acoating'of paint or other preservativeto the wires in an effective, rapid, and

economical manner. The device is so constructed that the paint can be automatically appliedand evenly coated by cheap labor and without danger to life or limb in its application.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of one embodiment of my invention as applied between two poles supporting overhead feedwires. Fig. 2 is a side elevation, partly broken away and in section, of the paint-applying mechanism; and Fig. 3 is a transverse section on the line 3 3 of Fig. 2 looking in the direction of the arrows.

The numeral 1 indicates an oblong can, preferably of galvanized iron, forming a tank to contain the coating liquid for coating the wires and having a lid 2 and a handle 3 shaped somewhat after the fashion of an ordinary washboiler. Secured to each end of the tank is a strap 4, of bar-iron, bent in the form of a U and spaced a slight distance from one side thereof. The strap 4 is further supported from the tank at the center and at one side of the center by angle-irons 5 and 6, of similar material, passing under and riveted to the base of the tank. At the point where the angle-iron 5 is joined to the strap 4 is journaled one end of a spindle 7, passin transversely through the tank and journaled at each side thereof. On the spindle 7 is a wooden core 8, fitting in and of the width of the tank, at the center of-which a' brush 9is carried, said brush-being of such diameteras to reach nearly to the bottom of the tank. At the outside of the tank a gear 101s :fixed on the spindle 7 .and meshes a gear 11,

one end and at its opposite end in'the intersection of-the strap 4 and the angle irontfi. The spindle 12has also fixedtoit a.pulley l 3 for the purpose of drivingthe earsand brush when the latter is rotated. irectly under the pulley -l3,is fixed a metal socket 14, in which is secured a-bar 1'5, telescoping at'its lower end with an extension 16 toper mit;the latters adjustment verticallyin either direction to compensate-for thedifi'erent heights of wires desiredto'be painted. Atthe lower end of the extension 16 apulley'1'7, adapted to be driven by acrank -18, is journaledsin alinement withthe pulley -13 and drivesthe fixed to a spindle -12, journaledzinthe-tank at same'by a rope or belt :19. For suspending J the tankto a wire are'rivetedv or otherwise secured twisted supporting brackets 20, passing upwardlyto a out the heightiofthetop of the tank and have journaled .in them grooved wheels 21. To each supportin bracket is secured an eye-2 2, horizontal y projecting awayfromthetank.

The construction so'far described constitutes the paint-applying mechanism, and the means for supporting it from a wire. In order that it may be made to travel along the wire as the paint-brush is revolved are provided brackets 24, which are to be secured near the bottom and top of two adjacent suporting-poles where paint is to be applied. n these brackets are journaled pulleys 25, and the brackets are so made as to be readily attached and detached from the poles in order that they may be shifted from one pole to another as the ainting proceeds. After the paint-tank has een sus ended from the wire to be painted by the w eels 21 a r0 e 26 is connected to one of the eyes 22 an passed about the ulleys 25 and brou ht to the other eye 22, wiere it is connected. One of the lower pulleys 25 is provided with a crank 27, by which it maybe turned to drive the rope 26. In the operation of the device the tank is brought close to one of the poles and made to traverse the wire by turning of the crank 27, or it may also be moved by pulling upon the lower run of the rope 26. At the same time the crank 18 is also turned, revolving the brush 9, which carries the paint from the IIO bottom of the tank and evenly applies it to the wire. By moving the device from pole to pole a continuous length of wire may soon be coated, leaving only a short piece thereof adjacent to each insulator to be coated by hand. In order that the section of the wire passing through the tank may be completely inclosed by the same, slots are made in each end, passing below the flange of the lid 2 when the latter is in place. v

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a paint-tank, brackets fixed at each end thereof, grooved Wheels j ournaled in the ends of the brackets adapted to support the tank on an overhead wire, a spindle journaled in the tank, a wooden core fixed to the spindle, a brush on the core, a gear fixed to the spindle at the outside of the tank, a second gear journaled on a spindle at one side thereof and meshing with the first-mentioned gear, a pulley fixed to the spindle of said second gear, a bar fixed to the tank telescoping with an extension at its lower end, a pul ey journaled in the extension, a belt passing over both of said pulleys for driving the brush, a rope fastened at each end of the tank and passing over the pulleys journaled on the brackets attached to the wire-supporting poles, means for driving the rope about the pulleys for moving the tank along the wire, and means for driving the pulley journaled in the extension for revolving the brush.

2. The combination of means to suspend a tank adapted to contain a coating liquid, from an overhead wire, means in the tank for applying the liquid, means for operating the applying means from the ground, and independent means for moving the tank along the wire.

3. The combination of a tank for containing a coating liquid, adapted to be suspended from an overhead wire, a brush journaled to revolve in the tank, means for operating the brush from the ground, and means for moving the tank along the wire.

4. The combination of a paint-tank, brackets secured at each end thereof, grooved wheels journaled in the brackets adapted to suspend the tank from an overhead wire, a rotatable brush journaled in the tank, means for operating the brush from the ground, and means for moving the tank along the wire.

5. The combination of a aint-ta'nk, means for supporting the same om an overhead wire, a revoluble brush j ournaled in the tank, and a telescopic bar extending from the tank carrying means whereby the brush may be revolved from the ground.

6. The combination of a paint-tank, means for supporting the same on an overhead wire attached at each end thereof, a revoluble brush journaled in the tank, gearing and a pulley journaled at the outside-of the tank, a bar having a telescopic extension projecting downwardly from the tank, means carried by the extension for driving the brush, and means attached at each end of the tank for moving the same along the wire.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE WELMAN.
