OZONE-.MACHINE SPECIFICATION forming part of Beissued Letters Patent No. 9,976, dated December 2`0, 1881.

' Original No. 185,040, dated December 5, 1,876. Application for reissue tiled November 3, 1880.

.To all whom it may concern:

Be it known that I, HANNAH MILSOM, of Butl'alo, in the county of Erie and State of New York, have made certain Improvements in 0zone-Machines, of which the following is a specification.

This invention consists in providing a siin pleand cheap machine for the generation,purilication, and emission of ozone, in the process by which the above objects are secured, and in the construction, arrangement, and material employed in the several parts.

The invention also consists in purify ing the y ozone without the use of chemicals or water,

except as hereinafter mentioned, by the passage ofthe ozone through the` porous earthenware walls of the machine, all as hereinafter described.

1u the drawing the ligure represents a vertical sectional elevation of one form of apparains, in whichy A represents a central tube or open pipe running the entire length of the same. This tube is constructed of porous material, such as earth enware, pottery, or their equivalent,v and unglazed, except the lower part, which sits in water. This tube acts as an ozone and air line, and its walls aid in purifying the ozone. The

' tube sits on the bottom of a dish or base, B,

phorus g is placed, or tubes or other receptacles may be employed, into which the phosphorus is put.

The base-dish B is made of any glazed ware or other suitable material capable ot' holding water, and non-combustible, and has sides c, forming a sort of bowl, with feet d d on the bottom to raise it from the floor or other place, so that an unmpeded passage of air may be had through the open bottom a. rlhe rim of the dish B is grooved, or has a flange, e, so that a close joint can be made with the walls of the ozone-generatin g chamber C. These walls are also constructed of porous earthenware, or its equivalent, and may have mica windows ff in f the sides or elsewhere, so that the interior of the machine may at all times be visible and the combustion orox'dation of the phosphorus noticed and controlled, as hereinafter more particularly stated. The walls of this chamber C, being made of porous earlhenware, orits equivaient, aid in the purification of the ozone in the same way as the walls ofthe tube A, thus securing a greater extent of porous material, through which the operation may proceed, it

being of the essence ot' my invention that such this is set a removable dome or cap, D, made t,

high enough to give an upright play to the tube A, which is raised or lowered by a cord or wire, m, or other suitable device, to increase or diminish the height ot' the phosphorus g above the surface of the water contained in the base B, or to submerge the phosphorus altogether below the surface of the water. In the drawing the phosphorous sticks are shown below the water-level h, which is the case when the machine is not in use or operation. The raisingorloweringof the central tube, A, raises or lowers the phosphorus with it, and by this means the height of the phosphorus above the surface of the water, and consequently the rate' of its combustion or oxidation, is controlled. The windows ff are for the purpose of noting this from the outside, as before stated.

The cover or dome D has several openings or perforations, d i, therein for the escape of the ozone which passes from the chamber (3v I through the porous walls of the tube A. This ozone may also escape at a.

The foregoing describes the general construction and arrangement of one form of the apparatus and its parts butparticular stress is laid l`,

on the porosity of the material out of which the walls of the tube A and chamber C are madeviz., porous earthenware, or its equivalent-as ozone being thereby emitted, the acid dropping down inside into the waterin the base-dish B, whence it may be drawn eti' and fresh watgi` supplied when necessary.

The operation is as follows: The central tube or pipe, A, is raised sutiiciently to expose the phosphorus slightly' above the water-level h, when the slow oxidation of the phosphorus commences, the fnines arising in a cloud-like vapor into the ozone-separating chamber C, where they mingle with the air constan tl y coming therein through the walls, the phosphorous acid and other-deleterious substances dropping into the water below, and the ozone passing through the outer walls of chamber O directly into the room and through the walls of the eentral tube, A, and out at the bottoni a or top of said tube, according to the draft. Air and ozone are therefore constantly passing through these walls when the apparatus is 1n operation, which is an important feature of my inventioii, as l believe myself to be the rstwho ever utilized this material for this purpose. 1 claim that these porous walls, made of this or similar ware, aid greatly in freeing the ozone from the acid, all tests showing this to be the case. No other purifying,fiiiediiiiii, such as chemicals, Snc., is employed in this apparatus.

.A suitable packing, k, is used around the junction of the cap D, tite tube A, and chamber C, also where the chamber C and base Bjoin, if necessary.

By this machine the expense of an ozonegenerator is greatly reduced, a. safer, better, and simpler apparatus is supplied, and a better quality of ozone is produced.`

1 disclaim as porous cloth, wood,wire work, and such substances,and eontine my meaningto earthen ware or other un glazed ware or pottery.

The form of the machine is not important so long as the essential parts are represen ted. By this construction the ozone generated has full egress all around through the walls of chamber C and through the walls of the tube A and out at either its top or bottom, according to the draft, as stated.

1n a large machine several pipes A may bel employed with corresponding openings in the bottom of the base B and phosphorus-holders attached thereto. For ordinary machines one central pipe will be sufficient, as shown.

The base-bowl B and ozone-chamber'walls C may be made of metal having a non-corrosive surface, like porcelain, &c., which will. make the machine less liable to damage or breakage by accident. They will have the same coilstruction otherwise, and thecentral poroustube. A, will then do all the work of purifying, which, it is thought, will be sufficient for a small inachine.

The construction of parts, the material employed, and the fact of purifying ozone without the aid ot' chemicals ot' any sort, cloths, or water (except that used iu the base-dish B) aie the important features of my invention.

1 claim as new- 1. The ozone apparatusconstructed with the base B, with the tube opening or openings a a' therein, the central tube or tubes, A, with the phosphorus-holder b, the separating ozonechamber C, and cap D, substantially as hereiny shown and described.

2. The process herein desciibed,fwhich colisists in the generation, purification, and emisiey sion of ozone by the slow oxidation of phos phoru's in a chamber with inclosing walls of porous material, such as earthenware, or its equivalent, whereby the separation and retention of the acid fumes and the egress of ozone are effected, substantially as herein shown and described.

In witness whereof I have hereunto signed my naine in the presence of two subscribing witnesses.

HANNAH MILSOM. \Vitnesses:
