SPECIFICATION forming part of Letters Patent No. 668,419, dated February 19, 1901.

Application filed August 21, 1900. Serial No. 27,602. (No model.)

To to whom it may concern:

Be it known that I, OSCAR RUSSELL, a citizen of the United States, residing at Sycamore, in the county of Dekalb and State of Illinois, have invented new and useful Im provements in Machines for Insulating Overhead Wires, of which the following is a specification.

My invention relates to machines for coating overhead electric wires with a liquid insulating material; and the object of my invention is to provide simple and efficient means for thoroughly coating the wires either before or after they have been attached to the poles. I attain this object and advantage by means of the construction shown in the accompanying drawings, which form a part of the speci-" fication, and in which Figure 1 is a central longitudinal section of a machine constructed in accordance with my invention, the hinged cover being open. Fig. 2 isasimilar view, the cover being closed. Fig. 3 is a plan view of my invention, the cover being thrown back. Fig. 4 is a transverse section showing the spring-bearings of the pulley. Fig. 5 is a plan view of the outside of the cover.

Like numerals of reference designate like parts wherever they occur in the different views of the drawings.

In said drawings the numeral 1 designates a box or casing having inclined lower sides or bottom 2 and provided with a reservoir 3 for containing a liquid insulating material, the bottom of said reservoir being inclined in order that the liquid may flow toward the center thereof. A pulley or sheave 4 is j ournaled in the reservoir on a transverse shaft 5, having spring-bearings 6, which permit the pulley to rise and fall as inequalities in the wire ride over it. tition 7 in the reservoir 3 consists of two inclined sections 8 9, apertured to admit the pulley or wheel 4 and resting on ledges or supports 10, secured to the sides of the casing 1. An arm 11, pivoted in bearings 12 on the section 9 of the reservoir-partition 7, carries at its opposite end a rubber block 13, having a semicircular groove 14 in its face. This block is attached by screws or bolts to the seat 16, secured at one end of a shank 17, which extends down through an opening 18 A horizontally-extending parin the section 9 and aspring 19, surrounding the shank, and forms a cushion-seat for the rubber block to allow for kinks and inequalities in the wires being treated. A similar arm 11 is pivoted in bearings 12 on the hinged cover for the box or casing, and said arm has a similar block of rubber 13, seated on a shank 17, extending through the cover 20 and having a spring 19 surrounding said shank. These two arms 11 11 with the grooved blocks and the springs, form a pair of yielding jaws which form guides for the Wire. The springs 19 19 permit the jaws to separate a sufficient distance to compensate for kinks or inequalities in the wire.

A pair of wipers consisting of grooved rubber blocks 22 22 are suitably connected to flanged seats 23 23, secured to the ends 24 24 of levers 25 25. These levers are fulcrumed intermediate their ends at 26 26 to the inside surface of the cover 20, and their ends opposite the wiper-jaws are connected to the arms of a U-shaped spring 27, secured by keepers 28 to the cover 20. The tendency of the spring is to close the wiper-jaws, and the levers 25 25 may be separated to open the jaws by means of a key 29, pivoted in the cover 20 and having two arms 30 30, which bear at opposite points upon the levers 25 25 when said key is turned by the crank or handle 31 on the outside of the cover.-

A piece of rubber 32 is held bya clamp 33, attached to the inside of the cover 20, said piece of rubber having a groove 34 to bear upon the wire immediately over the wheel or pulley 4, and the purpose of said rubber piece being to wipe back the superfluous insulating liquid as the wire passes over the pulley or wheel.

A ring or handle 35, connected to the shank 17 on the outside of the cover, serves to separate the jaws 13 13 when desired.

A roller 36 is journaled in bearings 37, secured inside the cover 20, which roller serves as a guide and support for the wire as it passes from the jaws 13 13 to the wipers 21 21.

A roller 38 is journaled in a hanger 39, having a slotted arm 40 adjustably mounted on the cover 20 at the inlet end of the casing. The arm 40 is seated upon an inclined support 41, secured to the cover.

Openings 42 43 are formed in the casing or box to permit the wire to pass through it, and an eye or loop 44 is attached to one end of the inclined bottom 2 to serve as an attach ment for a Wire or rope for pulling the device over the wire.

The operation of myinvention is as follows: The-cover 20 is raised and the wire to be insulated is passed through the openings 42 43 over the wheel or pulley 4, and when the door is closed the wire passes between the jaws 11 11 and the wipers 21 21". When the casing is drawn forward, the wheel 4 carries the insulating material up and applies it to the wire, and the rubber blocks and wipers distribute ituniforml y upon the wire at all points.

Having thus fully described myinvention, what I claim is 1. A machine for insulating overhead wires, consisting of a box or casing, containing a reservoir for insulating liquid, a wheel journaled to dip into the liquid, and spring pressed wiper-jaws mounted in the casing, substantially as described.

2. In a machine for insulating overhead wires, the combination with a box having a partition therein thus forming a well or reservoir for containing insulating material and said box at each end formed with a hole or opening for the passage of a wire, of the hinged cover and the central wheel dipping into said well, substantially as described.

3. In a machine for insulating wires, the combination, with a box constructed to contain liquid insulating material, and having a cover thereon, of the wheel mounted to dip into the liquid, of the spring-arms mounted on the cover of said box and provided with blocks having longitudinal grooves therein, of a first spring-actuated arm mounted on the cover and a second spring actuated arm mounted in the box and designed to act in combination with said first'spring-actuated arm, substantially as described.

4. In a machine for insulating wires, the combination, substantially as described, with a box having a reservoir therein for liquid insulating material and a cover, of a wheel mounted to dip into said reservoir, and a pair of spring-actualed arms bearing wipers and mounted on said cover.

5. In a machine for coating wires, in combination with a box having a reservoir therein and a cover, of a wheel mounted to dip into said reservoir, a first spring-actuated arm mounted on the cover and bearing a grooved wiper, and a second spring actuated arm mounted in said box and bearing a grooved wiper, said second arm being designed to act in combination with said first arm to embrace and wipe the wire.

6. In a machine for coating wire, the combination with a box having a reservoir therein and an inclined horizontally-extending partition, the wheel dipping into said reservoir, spring-actuated wiper-jaws mounted to embrace the wire, and guides for said wire, substantially as described.

7. The combination, substantially as described, of a reservoir constructed to contain liquid, spring-bearings, a sheave mounted on a shaft journaled in said spring-bearings, said sheave being located to dip into the liquid in said reservoir.

8. The combination, substantially as described, of a U-shaped spring, two levers fulcrumed intermediate their ends and secured to the arms of said spring, and grooved blocks mounted on the free arms of said levers and positioned to form jaws for embracing the wire.

9. In a machine of the class described, the combination, substantially as described, of a pair of pivoted arms, grooved blocks mounted on the free ends of said arms, a shank mounted to slide and secured to said arms, and spiral springs surrounding said shanks and mounted to actuate said arms.

In testimony whereof I have hereunto set -my hand in presence of two subscribing witnesses.

OSCAR RUSSELL.
