TO ALL WHOM IT MAY CONOERN:

Be it known that I, THOMAS LEACII, of Taunton, in the county'ot Bristol, and State of Massachusetts, have invented a new and improved Ice-Pitcher; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure' l is a vertical section.

Figure 2', a horizontal section.

In th'isinvention a. detachable and removable lining, of glass, china, o1' earthenware is employed, and in connection with it acombined valve and filter of peculiar construction, together with a novel and convenient device for holding the lining firmly inthe pitcher, and at the same time preventing it from fracture by the sliding offthc ice.

IIithert'o ice-pitchers have been made either without any lining at all or with double walls, so attached together that the inner onen-cannot be readily removed, but constitutes a permanent part of the pitcher. Ierhaps, in one or two instances, a pitcher has been constructed having a removable lining or inner-wall, but in that case such wall was made of metal, and it has been foraminatcd for`the purpose of allowing the water to flow freely through it.

My invention is entirely unlike any of these, being confined to a removable lining or inner wall of glass, carthernware,vor chinaware, with the accompanying improvements above referred to, when constructed as I will now proceed to set forth. i

In the drawings, A is the metallic outer wall of the pitcher, B its cover, C its handle, and I) itsnose. To thc bottom oi this pitcher, on the inside, is firmly attached a ring or ilangc, E, of the same metal, and having several openings, e e, so that the air sha-l) freely pass around the ring, and to and from the space within it.

Inside of this pitcher I set another pitcher, F, composed of glass, earthcnware, or chinaware, and so eonstructed ns to rest firmly' upon lthe ring E at tho bottom, and to tit around its top at a a, accurately against the outer walls of the ypitcher at their top, leaving a uniform air-space around thc sides and under the bottom of the glass lining or inner wall. y

G is aring, of plated metal or silver, which fits down upon the top of the glass, for the purpose of confining it in position, being provided with a dange, g, all around its inner edge, which projects down inside Iof and almost or quite in c ontact with the glass lining, and completely protects the upper edge of the glass or 'other material of which the lining is made from being brokenby the ice sliding forward when the pitcher isinclined. This ring is provided with a widened or expanded lip, L, which covers the greater portion ot' the nose of the glass lining, leaving a space, however, at its end, for the water to flow ont through.

Under this lip is a. filter or screen, H, and inclined foraminated plato of metal, attached at its upper odge to thc inner edge of the lip, and fitting closely to the lower part'ofthe nose or spout of tho glass lining. A ilange, i, extends around this filter on its upper side, forming, in conjunction with it, a kind of bex having a. foraminuted bottom. This box is covered and closed by a lid or valve, J, of plated metal, hinged just under the lip L, at the upper edge of the screenor filter. i

The valve opens upward by the pressure ot' the water when the pitcher is inclined, and shuts down again, hy its own weight, when the pitcher is placed erect. The ring, filter, and valve are thus all connected together, forming one piece, which can be readily inserted or removed when Athe lid of the pitcher is raised. When in place, it is conincd there securely by means of a screw-rod, r, passing through it horizontally, and through two lugs on the side of the wall A or the nose D, at the upper edge thereof. A ridge may be raised across the lip L, at the suitable point, to conceal the screw-rod, and give the ring a neater appearance.

One of the great objects of this invention is to preserve the ice and prevent its melting as long as possible, thereby saving the material and making the supply of coldwater more constant and unfailing. This it does to coms 2 a remarkable degree, preserving the saine quantity of ice, under the saine circumstances as otherpitchers, as has b een ascertained by careful experiment, at least twenty per cent. longer, in consequence ofthe nonconducting quality `of the lglass, and the fact el' its being protected by the outside wall.. Another'great object is to check, or entirely prevent, the condensation of moisture from the air upon the outer walls of the pitcher. rlhe ice, being plaeedin thcinner pitcher, and the latterbeing made of glass, or other similar non-conductor. of heat, the outer wall A will remain all the whilecompai'atively warm, and scarcely any 4condcnsation will take place upon it, leaving it neat and dry under almost all circumstances. The diier-` ence, in tliislrcspeet, between my improved pitcher and those which have an inner lining of metal, is very great.

`fI-n the third place, the inner pitcher can bereadily renioved` it' dcsired,and vthe outer wall A. will then form aliandsome pitcher of the usual forni and construction. If, therefore", by any'accidcnt, the `glass lining sheuliibebroken, `it Vdoes not destroy the pitcher, or prevent its b'eing used all thewhile. ,l 4

`I design manufacturing the pitchers of certain definite sizes and shapes, to bc nuniberedfsothat when the lining-of one is broken, the owner need only order a lining et' such a number, wit-hout sendingtb'c: pitcher, to

hel fitted with a lining, as'hcrctoforc.

rllic pitcher can be readily cleaned in all `itsparts, as will be seen from what has already been stated. The ringiltcr, v4and valve can` always be kcptfi'nthe neatest order. No dirt frein "the ice or water can 'iusinuate itselffnnderr around the glass. r` It is diiiicnlt to"conceive of any method of construction which will renderit possible te produce a. neate'r and more clfeanly article of the kind than that above described.

V Having thus described my invention, l' do not wish to limit nlyscltto the precise details of construction herein set forth, and particularly to the ring or circular plate for holding the lglass lininfr in place, for other devices, similar in general principles, but different in construction, might, perhaps, be, employed for the same purpose, to wit, holding the glass in place and protecting ih from fracture; but

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a detachable and rcinovablc glass, eorthcnware, or chinaware lining, or interioi` pitcher, with the nictallic pitcher A, and a ring, plate, oro'ther equivalent device-fer holding the-pitcher and lining together, and yet permitting the lining to be removed when necessary.

2. '.lhc ring Gr, having therim or ange g, when used in connection with -the walls A andthe lining F, in the manner and for the purpose set forth. l

The combination oi' the ring G, iilter ll, and valve J, forming a'neat atta'chahle and removable apparatus for icc-pitchers, substantially as set forth.

4. The combination of the apparatus, above referred to with the wall A and thc screw-rod r, substantially as described. i
