PIPE-PROTECTOR.
Specification of Letters Patent.
Patented Mar. 11, 1919.
No Drawing. Application filed January 23, 1915, Serial No. 3,876. Renewed Jiily 25, 1918. Serial No. 246,783.
To all whom it may concern:
Be it known that I PETER MoILnoY, a gtates, and a resident of Allison Park, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Pipe-Protectors; and I do hereby declare the following to be a full, clear, and exact description thereof. Y
My present invention relates to a new and useful method or process for treating pipe or conduit unitprotectors of the type described in my Patent No. 1,120,731.
The protector disclosed in this patent consists essentially in a sleeve which is of fragile material and is applied to the pipe or conduit unit either externally or internally thereof to prevent the threads from being heavily coated with enamel. During the coating process some of the enamel seeps in between the protector and the threads of the pipe, and while the protector as originally made was of absorbent material and absorbed the greater part of the enamel, it was found that there was a tendency of the protector to stick to the pipe because of the adhesive properties of the enamel.
The principal object of my present invention is therefore to provide a protector sleeve in which all liability of the protector sticking or adhering to the pipe or conduit unit y will be eliminated.
In accordance with my present invention the protectors which are preferably formed of paper (although any other absorbent material may be substituted) are dipped in a bath consisting of a saturated solution of rosin, and this solution of rosin is produced by mixing powdered or granulated ros1n with benzin, suflicient benzin being used to make the mixture relativelythin, so that it will have substantially the same con-. sistency as ordinary shellac; (It would of course be. possible to produce the liquid bath of rosin by merely melting, over a flame a quantity of powdered rosin. When rosin is so melted however the resultant product is a sticky, stringy, mass which could not be expediently employed in this process.) It is desirable in the present invention that the rosin solution be thin enough so that the protector will be sufliciently impregbenzin has gone 01f in vapor the protector is in reality impregnated with rosin.
It has been found in practice that when the protector has been treatedby the process above described it will readily absorb all but a very small portion of the enamel entering between the protector and the pipe during the coating operation, while the protector will not adhere to the threads of the pipe as the rosin appears to be insensible to the adhesive properties of the slight amount of enamel which remains in the threads of the'pipe. In this latter connection it may be well to explain that the amount of enamel which is not absorbed by the protector and is allowed to remain in the threads is only suflicient to make an extremely thin coating on the threads and sufficient to keep the same clean during installation.
.What I claim is:
1. A thread protector for conduits consisting'of a tube formed of relatively stiif absorbent material, the material of said tube being impregnated with rosin.
2. The combination with a conduit having a threaded end, of a protector for, said threaded end, comprising a tube for covering the threads of said end, said tube being formed of relatively stifi absorbent material, the material of said tube being impregnated with rosin.-
3. The combination with a conduit. having a threaded end, of a protector for said threaded end, comprising atube for covering the threads of said end, said tube being formed of relatively stiff absorbent material, the material of said tube being impregnated with an indurating material.
In testimony whereof, I the said Pn'rnn Witnesses:
