Description

' The compression of the covering e thus produced Will prevent the expansive eiiort of the ice from being 'transformed into a bursting` stress within the pipe sections l.

The diameter of the covering et will be determined by the diameter of the pipe Within which the device is niounted, the eoe'liicient of elasticity of the material from which the covering 4: is fashioned also serving to del termine the diaineter of the resilient portion of the device. The diameter ot' the pipe and th-ooeflieient of elasticity of the material from which the covering/l is fashioned, being known, the size of the said covering fi may be readily computed; or, if desired, the size of the covering` el inay be determined experimentally.

The core 3 which preferably is otinetal, serves to retain the device in` place, and the terminals of this core 3, protruding beyond the covering e, are adapted to receive the means whereby the device is attached to a pipe. The covering t is of substantially the saine cross section throughout its length, and being retained securely. in position longitudinally of the pipe section, by means of the nietal core 3, it cannot readily become bent, interfering with the flow of the liquid in the pipe, and serving as a lodging place for any dirt of 'foreign niatter'whichv may be carried in suspension by the liquid in the pipe.

eaeoee lt will be seen, from` the foregoing, niy invention presents, in a simple and pensive form, a thoroughly ett'ective ir ne whereby vv ater pipes may be prevented troni freezing and burst-ing in the Winter season.

Havin thus described my invention, Wh l claim as new, and desire to prot-eet, by Letters Fatent, is

l.. ln a device of the class described, pipe; a core disposed Within the pipe, and being attached tothe pipe near the end thereof;v a resilient covering surrounding 5e the core and being shorter than the core.

2. In a device of the class described, pipe; a core disposed longitudinally of the pipe in the interior thereof, and l attached to the pipe near the ends thereof; 5 and a resilient covering surrounding the core and being rigidly attached thereto, eoveringbeing shorter than the core.

3. The combination with a pair er pipe sections, of a core disposed in each section eo and arranged to extend terminally into the other section; and resilient coverings surro riding the cores, the said coverings being cut away to provide places ot' `attaclnnent between the cores and the pipe sections; the e terminal extension of each core, with resilient covering, being arranged to extend past the bared portion-of lthe other core.

ln 'testimony that l claim the foregoing' as niy oWn, l have hereto atliXed my f* nature in the presence of two Witnesses.
