Be it kno'wnthat I, CHARLES nmitnl.l BL'EBBING, of the city and county of Philadelphia, and State of j .1

Pennsylvania, have invented a nexr and useful Improvement in Copper-Lined Bath-Tubs; and I do hereby declare that the following is a full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of `reference marked thereon.`

'The nature of my invention will he `understood. bythe following description.

In lthe accompanying draviings, whichform a part of thisspecicntion- Figure 1 is anisc'metrical view of the-improved tub.' Y

Figure 2 is a. cross-section of the same` Like letters in both the gure's indicate 'the same parts. r i I The usual mode of lining the tubs is to4 joint the lining iii the bottom, and consequentlyhe tubs frequently4 leak, on account o-the loosening of the joints, caused by thespringing of the sides. of the tub. The joints, ivhich are usually in the corners, 'are also loosened by the shrinking of 'the `wooden bottom, and also bythe weight of a, Aperson when stepping into the tub.

" WTQ obviate these diioultes, I Tine the" tubs without the bottom seams, making the 'main pantt''o1"tl1el lining of n lsinglepiece, B, 'and soldering the end-pieces, C C, thereto, as represented in g. 1. Consequently the tendency to leakage, caused-by the springing of 'the sides, shrinkage of the bottom, die., is obviated. The` 4baths are also much more durable than those of ordinary construction, effecting a great saving in the item of repairs, besides avoiding the trouble incidental to leakages. The liningat the bottom of the tubs is also much smoother than when ther t to the wood. v V v According to the present plan of constructing bathing-tubs, in order to furnish as secure a joint as possible in 'the bottom of'the tub.,thick sheets of metal have of necessity been used'; andas hard metal, such as zinc and copper, is much more expensive than the softer metals, such as lead, the latter has gradually grown into use, its cheapness alone recommending it.` Many objections to, the use of lead fcxbathing-tubs could readily be advanced, such, for instance, as itsmore or lessgl'iability to corrode; and especially is it objectionable when used for hot bathsf'as the vapor that vill ris@ no matteihow slight the same maynppear to be, is most injurious. When the tub is lined with copper, all these objections are entirely removed. There is corrodeslwhen subjected to the action of nitric or other like acids.

According to my present plan, the seams inthe bottom being entirely dispensed with,'all danger of leaking no vapor 'or other unwholesome influence, no matter how great the heat; and it is wellknown that copper only is entirely removed, very thin sheets of metal can safely be used, and the .tub is therefore not only much more durable, but far lighter and much neater in appearance'.

Having thus fully described my invention, what I claim therein as new, and desire to secure by `Letters Patent of the United States, is l A bath-tub lining made of sheets of hard metal, such as copperor'zine, consisting of the`partsB CC, nhen the same are constructed and arranged as described.

In testimony whereof, I have hereunto set my hand and aflixed my seal, this fourth day of March, 1867.
