DEVlCE FOR THAWING ICE FROM PIPES.

SPECIFICATION forming part of Letters Patent No. 529,204, dated November 13, 1894. Application filed March 14,1894. Serial No. 503,593. (No model.)

To aZZ whom it may concern.-

Be it known that I, ISAIAH I-I. SIMPSON, of Brunswick,in the county of Cumberland and State of Maine, have invented a new and Improved Device for Thawing Ice from Pipes, of which the-following is a full,clear,-and exact description.

The invention relates to devices for thawing ice from pipes, such as shown and described in the Letters Patent of the United States, No.458,503,granted'to me August 25, 1891.

The object of the present invention is to provide a new and improved portable device, which is very compact in construction,easily manipulated, and arranged for rapidly thawing ice formed in water pipes.

The invention consists principally of a revoluble boiler, through which circulates the water to be heated and forced into the thawing pipe.

The invention also consists of certain parts and details, and combinations of the same, as will be hereinafter described, and then pointed out in the claims.

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

Figure 1 is a side elevation of the improvement. Fig. 2 is a sectional plan view of the same; and Fig. 3 is a transverse section of the boiler, on the line 3-3 of Fig. 2.

The improved device is mounted on a suitably constructed base A supporting the brackets A and A in which are journaled the hollow trunnions B and B of a boiler B, made in the form of a drum and adapted to be revolved, for the purpose hereinafter more fully described.

The hollow trunnion 13 connects with a water supply pipe 0, leading to a pump D of any approved construction, and mounted on into water-ways B formed in the head B of the boiler B, the said water-ways being preferably formed in the manner shown in Fig. 3, so that the water entering the water-ways through the trunnion, circulates through the entire head, to finally pass into one end of a pipe F, arranged within the boiler and formed preferably into two concentric coils F and F through which the water circulates after leaving the water-ways in the head B The end of the larger coil F passes through the rim B of the boiler B to 'then connect on the outside of the rim with the pliable pipe G,

adapted to be passed into the pipe to be thawed, it being understood that the said pipe G is coiled on the rim B of the drum boiler and may be readily uncoiled therefrom, as needed, by revolving the said boiler. The rim B is also provided with openings to permit the escape of the smoke and gases from the interior of the drum. The other, hollow trunnion B is in alignment with a plumbers or tinsmiths blast lamp H, of any approved construction andconnected with the supply vessel I, located on the base A.

Now, it will be seen that the flame of the blast lamp 11 passes through the hollowtrunnion B into the interior of the drum boiler B, to strike principally the opposite head B so as to rapidly heat the water circulating through the water-ways B in the said drum B The heat also acts on the coils F and F so that the water passing through the said coils, after leaving the head B is heated to a high degree by the time it passes through the thawing pipe G.

It is understood that when the device is in operation, the pump is kept going, so that water is constantly forced through the boiler to pass. into the pipe G, which latter is forced into the pipe to be. thawed and as it discharges hot water, the ice is rapidly melted in the pipe. The hot water flowing out of the pipe to be thawed, is collected in a receptacle connected with the pipe E, so as to be returned by the lrunnions, of which one is connected with a water supply, and the other forms an inlet for the heat, the said boiler being formed at one of its heads with water-ways connected with the trunnion having a water supply, and a pipe coiled within the said boiler and also connected with the said waterways, substantially as shown and described.

2. A device for thawing ice from pipes, provided with a revoluble boiler having hollow trunnions, of which one is connected with a water supply, and the other forms an inlet for the heat, the said boiler being formed at ISAIAH I-I. SIMPSON.
