Gent. 1, 1935. s M HUDSON 2,016,201
PIPE COATING MACHINE Filed May 29, 1934 Patented Oct. 1, 1935 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to a new and useful improved machine for coating pipes, and has for its object to provide a simple and eflicient machine that will keep the'coating material hot and in a liquid form so that it will fiow freely to the spreading jaws as the machine is moved along the pipe being coated. Pipes that are laid under the ground for carrying oil and gasoline to distant points are always coated with a suitable material to prevent corrosion which is usually applied by pouring the coating material on the pipe and using a cloth operated by two men and drawn back and forth under the pipe to thoroughly cover the under side of the pipe. By the use of my present invention the entire outer surface of the pipe is coated as the machine is moved along the pipe.
The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claim.
In the accompanying drawing,
Figure 1 is a side elevation of my invention in position on a pipe as the latter is being coated.
Figure 2 is a top plan view of Figure 1.
Figure 3 is a detail section of the coating jaws in the position they occupy on the pipe when the coating is being done.
Figure 4 is a side elevation of a modification of my invention.
Referring to the accompanying drawing, forming part of this specification, and in which like reference numerals designate like parts through the several views thereof, I designates a metal receptacle mounted on two legs 2 each of which has a roller 3 having a concaved surface adapted to fit upon the pipe 4. The said receptacle I is provided with a cover comprising a fixed, or stationary, portion 5 extending across the center of the receptacle I and two hinged sections 6 hinged at I to the stationary portion 5. Projecting from the bottom of the receptacle I is a pipe 8 having a flange 9 on its lower end. The spreading jaws III are hinged together at II and are each provided with a flange I2 at its upper end which fit up against the flange 9 and are held thereto by the bolts I3. The jaws ID are sufficiently large to leave a space I4 between the jaws and the pipe 4. The coating material flows from the receptacle I through the pipe 8 into the jaws I0 and onto the pipe 4. As the receptacle I is moved along the pipe 4 the coating material flows onto the pipe and the latter is thoroughly covered with the coating material without any further operation. Mounted on the top of the receptacle I is an oil receptacle I5 having a pump I6 to force air into the receptacle I5 to force the oil in a vaporized form to the pipe I6. The said pipe I6 is provided with a number of apertures throughout its entire length through which the vaporized oil is forced to provide the small flames II that keep the material in the receptacle I, and also the pipe 8, heated and in a liquid form so that it will flow freely to the coating jaws ill. The receptacle I is provided with a handle I8 on each side by means of which the machine is moved along the pipe as the latter is being coated.
In Figure 4 I have shown a modification of my invention in which the receptacle I9 is provided with a large pipe 20 leading from the receptacle I9 to the coating jaws 2|. In the modification the coating jaws follow the machine so that the wheels or rollers 22 do not run over the coating material after it is applied to the pipe.
Having thus described my invention, what I claim is:
A pipe coating machine comprising a receptacle, legs upon which said receptacle is mounted, rollers mounted on said legs and adapted to fit the pipe to be coated, a pipe projecting from the bottom of and communicating with said receptacle and having a flanged lower end, two jaws hinged together and each having a flange at its upper end adapted to fit against the flange on the lower end of the said pipe, said jaws being removably secured to the flange on the said pipe, an oil tank mounted on said receptacle, and a perforated pipe surrounding the said receptacle and the pipe leading from the receptacle to the jaws and connected to said oil tank.
