' To all whom-it mag concern:
as a result of the 'freezing.
'Be it known that I, JOHN M. .VERRE, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Antibursting Attachments for Tanks, Pipes,&c.; and I do hereby declare the following to be. a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in. anti-bursting attachments for tanks, pipes, etc.
1 An important object of this invention is to prevent tanks, pipes, etc., from bursting expansionof water upon A further object of the invention is toprovide an anti-burstin attachment for tanks, pipes, etc., comprisin a piston opcrating in anair cylinder, said piston being sectional view through a tank having adapted to compress the air within the air cylinder, upon the increased pressure with-- in the tank caused by the expansion of the Water.
Other ob'ects and advantages of the inventionwill be apparent during the course of the following description.
-.In the accompanying drawings forming apart of this specification and in which like. numerals are employed ,to designate like invention,

sectional view "through a tank having my improved anti-bursting attachment arranged therein, the same being shown inverted, and,
Fig. 8 is a central longitudinal sectional View through a tank, having my'im roved. anti-bursting attachment arranged t erein.
In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 designates a tank having a top and bottom designated by the numeral 11, said tank having the usual inlet pipe 12 and an outlet pi e 13.' c
y invention comprises a cylinder 14 open at one endas at 15, said cylinder having ar- "ranged therein a piston 16. The piston 16 comprises a circular piece of cork 17 and a metallic disk 18. cap 19 having screw threaded engagement with the open end of the cylinder 14 is provided with an annular flange 20 adapted to prevent the piston 16 v I ,from slipping out of the c linder 14. In the form shown in ig.-1 spokes 21 serve to support the cylinder 14 centrally within a. tank, though it is obvious thatany suitable means may be employed to arrange the cylinder within the tank in the proper,
place.
Upon the expansionof the water within the tank as a result of freezing, an upward pressure will be exerted on the plston 16 within the clinder with the result that the --air within t e cylinder will be compressed thus affording sufiicient space to permit of the expansion of the Water without burstin the tank.
n the modified form shown in Fig. 3, the
In the form shown in Fig. 7 ,-the cylinder 14 is arranged within the tank 10 near the bottom thereof, and the cap 19 is dispensed with.
In the form shown in Fig. 8, the opening in the cylinder 14 is arranged near the top of the tank 10 and the expansion of the water causes the air in the top of the tank to force the air within the cylinder within a smaller space.
In each form of the invention the piston 16, owing to the-weight or the metallic disk 18 on the bottom of the cork member 17 and forming a part of the section, will be held downwardly within the cylinder 14 and the weight of the piston together with the frictional engagement of the cork 17 and disk 18 with the interior wall of the cylinder 14 will offer sufiicient resistance to upward movement of the piston 16 within the cylinder 14 to prevent the piston from being moved upwardly by normal pressure of the water upon the under face of the disk 18. The piston 16, the main portion of which being formed of cork, will also cause an air and water tight fitting of the piston 16' within the cylinder 14, thereby preventingthe air from escaping from the upper portion of the cylinder 14 about the piston 16 and at the same time preventing water from passing into the cylinder '14, Any water which may reach the main portion of the cylinder 14 results in a swelling or an expansion of the cork portion 17 of the piston 16 and thereby causing atighter fitting of the piston 16 within the cylinder 14 and increasing the friction and in this manner assisting in retaining the piston 16 in the lower end of the cylinder 14 until forced upwardly by the expansion of the water within the boiler, tank or pipe in which the cylinder 14 is positioned, owing to freezing of the water and upon'such expansion of the freezing water the piston 16 will be forced upwardly within the cylinder 14. As soon as the excessive pressure upon the bottom 7 of the piston 16. is relieved by a rise in temperature and contraction of the water,
however, the compressed air within the cylind'er-14 will co-act with the piston 16 or metallic disk 18 thereofto return the piston to its normal position within the lower end of the cylinder 14. This is true of each form of the invention and it is believed that the operation may be clear without detailed description thereof.
\Vhile I have shown and described the preferred embodiment of my invention, it is understood that I may make such minor changes in arrangement and construction of parts as will remain within the spirit of the invention and the appended claims.
Having thus described my invention, what I claim is:
1. A device of the class described comprising the combination with a liquid reservoir, of a cylinder supported therein and having the lower vend thereof open, a plug fitting withinthe cylinder at the open end thereof and adapted to be moved u pwardly within the cylinder upon expansion of the liquid in the reservoir, said 'plug being adapted to move downwardly upon a decrease of the pressure against the under face thereof by gravity, and means to' prevent said plug from moving out of the lower end of said cylinder. l
2. A device of the class described comprising the combination with a liquid reservoir of a cylinder supported therein and having one end open, and a weighted plug adapted to be forced in one direction within further I said cylinder by expansion of-water within the reservoir, said plug being adapted to move by its own weight and by expansion of air working on an o'pposite face thereof upon contraction of the water in the reservoir.
