IMPROVEMENT IN PRESERVE-CANS.

Specification forming part of Leticls Patent No. 23,962,

November 1562.

To all whom, it may concern-z..-

Be it known that I HENR'i O. NIorIoLsoN, both of Mount Washington, Hamilton county, ()hio, invented a new and useful Provision-0an for the Preservation of Substances by Hermetically Scaling; and I,do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of thisspecilicution.

To the use of self-sealing cans as at present constructed there are many and serious objections, which will be apparent when we come to consider the many different kinds of materials of which they are composed. ing, cans such as are now in use may be divided into two classes to wit, mineral and Familiar examples of the former are earthenware and glass jars, and of the second, tin. To the first of these-housekeepers raise the serious and reasonable objections of their frangibility and of the great difliculty experienced in securelys'ealing them, because of the irregularity of their shrinkage in cooling after being heated for the purpose of expelling the air, and also because of the difficulty of forming a good and lasting eonnecearthenware or glass only practicable mode that can be adopted,- an illustration of which may be found in the glass jars in common use for the preservation of prunes.

Another objection to the use of pottery ware arises from the glaze of such ware, because of the presence of large quantiticsuof poisonous metallic oxides, which are easily acted upon by the acids of the fruits, &e., intended to be preserved. In reference to the second or tin cans, all persons at all conversant with the nature and properties of fruits will readily and instantly percciveihow little adapted are any or the baser metals for their preservation, because of the presence of the vegetableaeids in ihenn'whieh act vigorously upon such metals, corrot'ling the cans, entirely destroying the filler and more delicate flavor of the l'r nit, and comnninieatingto'it disagreeable metallic taste, "at once unpalatable and unwholesome to those using them.

James F. MARTIN and Self-seal-v Another serious objection to the tin can is the impossibility of perfectly excluding the air.

The numerous soldered joints and the li-ability of tin to become dented in use cause a large percentage of the cans to be defective, resulting in the destruction of the fruit in-- tended to be preserved; it has been found that with the use oftin, (because of its lack of rigidity and strength,) cans of'all sizes are compelled to be made with narrow and contracted mouths, causing great trouble and inconvenience in the insertion and removal of the fruit. Notwithstandingall these drawbacks, however, it is true there are many who, rather that be without the fruit,

eral jars, because of the liability of the latten to break; with heat or by any accident-a1 concussion, and becausefof the-liability of the glaze of stoneware niunications with the exterior.

objections, one that will liable to be broken, impervious to the air, and not subject to the corroding action of the acids contained in the fruits, &e., is the object of this improvement; and itfeousists in constructing cans forthe preservation of fruit or provisions of iron or other metal lined on the inside with a vitreous material capable of withstanding the chemical action of the acids of the fruit.

In the accompanying drawings, Figure 1 is a perspective view improvement. Fig. 2 is a perspective View of the under side of the cover. Fig; 3 is a side View of the cover.

of a can illustrating this posed bet ween the can. and cover to assist in whole interior surface, 0, is covered with a lining ofenamel or other vitreous body to resist the action 'of the acids contained inv the substances to be preserved. This lir ing may be applied by fusion or in any other efficient Way which will accomplish the object above set forth. The coverof the can may be constructed and lined with like material. A can thus constituted may be made as light as one entirely of glass or of clay, and still possess almost incomparably greater strength, and at the same time be as-free as common glassware from liability to corrosion by acids. It is therefore ec0nomical,wh0lesome, readily clcansable,and admits of being used season after season as long as desired. The metal on the exterior and the vitreous lining with-in afford such mutual support that neither the metal nor the glass is required to be as thick as is needfnl when used alone to prevent bending or fracture.

It is believed that a non-corrosive hermeticallysealed provision-can has never before been produced capable'of excluding the at mosphere from its contents after being subjccted to severe frost, or adapted to preserve perishable. articles of diet with snfiicient econ omy and success as to be extensively used for this purpose in long sea voyages.- It is also specific vitreous material for the lining thereof; neither'is it limited to any form of can or to anyspecific means of fastening thesame.

The following is that which is claimed as new in the invention of the above-named JAMES F. MARTIN and HEF RY G. NICHOLSON, andwhich it is desired to secure by Letters Patent:

" 1. A fruit or provision can 'to be hermetically-sealed or tightly closed, constructed of metal li'ned on the inside with a vitreous body to resist the action of acids contained in th substances to be preserved.

2. A vitreouslyenamelcd iron provision can or jar, substantially as herein set forth;

3. The combination of avitreouslydined inetallic cover with a preserve-jar, substantially as set forth.
