f Be it known that REN Manoir. citizen `tof the Republic of France, and resident of 53 Rue de Chateaudin, Paris, in the said gepublic, engineer, have invented new and Seful Improvements in Apparatus for lire paring a Mixture of Air and Sulfur Dioxid,

expanding device according to the present invention. Fig. 4 is a. 'lopgitudinal elevation and Fig. 5 a top view of an apparatus for producing and distributing the mixture of air and sulfur dioxid provided with said en` 4pending deslice. v A

. The expanding device consists in a box a oshetfmetal having a part b in which `are arranged series othurizontal tubes fr whose diameter increases from the lower part upward and are `asselniiled by means of bent tubes c (these tubes being fixed by means ofremovable bushings) in order to provide a number of coils of gradualhYr inY creasing cross' section equal to that at the bottles containing the liquid sulfur dioxid for feeding the apparatus'f.. The lower end of each coil is connected te the lin a tubular de bottle of sulfur dioxid a. while its upper i 3 a plan of an respective y iextreioity is connected to a free space (l tubular expanding device above described liquid sultur dioxid; u steam inlet aperture which 'is formed in the upper part of the bou a. and does not communicate with the room fi in which the coils are arranged.

The steam designed for heating purposes admitted in said space b'through an up- Aper inlet pipe c and owing to its Contact With the coils the sulfur dioxid absorbs heat therefrom and when it reaches the space d is entirely raporized and expanded. As a preventive means hi'iwever, in case some smali liquidl drops should remain in the mixture, there is. rovided a Wall f against which the sulfur ioxid impinges and which constitutes a baffling device over which the sulfur dioxid is made lto pass in order to escape through the outlet g; the upper part of the wall f is provided with a sloping portion fdesigned to ive reater security 4against the passage ofiqui In the top of the space d is provided an air inlet h so that it is a mixture et air and expanded sulfur dioxid which escapes through the outlet g. On one side of space d is provided an opening z' normally closed by a sliding door through which the action of the apparatus can be viewed.

As will be seen in Figs.- 4 and 5, the

is connected with the bottles n, a oontaining the liquid sulfur dioxid, these bottles being preferably placed upon a Weighing apparatus o in order to permit the operator to observe at ,all times the quantity of sulfur dioxid still remaining; the `gaseous mixture of air and sulfur dioxid as it escapes from space a flows in a known'lnanner in a pipe j which contains electrodes k con. nected with a dynamo Z in order to prodtlee electric sparks in the body of the gaseous mixture. The dynamo Z is actuated ""by ine-ans of a driving 'belt through the shaft ot a iii'an m which inits turn is actuated in the saine manner by the prime mover.

l chillin- A device for expanding sulfur dioxid and thoroughly mixing the latter with air, coniprising: a box; series of tubes in said box, the diameter of which increases from bottoni to top; bent tubes connecting said tubes together in each vertical row; a'connection piece on the lowest. tube in each vertical rau. for connecting it to a bottle containing in the wall of said box; a chamber at the upper part of said boi: connected with each.

vertical row of tubes; a partition in said as my nventoxn I have signed my name in chamber to act as `a bae; an inclined purl Jresence of two Wtmesses,1s 16th day 0f }0 tion at the upper edge of saild larttion; an member, 1910. air inlet aperture in the wal Q Sai-d Chmn 'Y ber; a latem aperture in the wal of the RENE MAROT latter for the dlscharge of the mixture of 1 expanded sulfur dioxd and air.
