Fig? 11 will Patented Mar. 17, 1931 .DPATENT OFFICE ERNST BEBL, OI DABMSTADT, GERMANY FILLING BODY FOR REACTION AND WASHING 'JPOWIZBS Application filed August 31, 1829, Serial No. 889,770, and in Germany September 18, 1888.

For filling reaction and washing towers and the like a large series of different filling bodies of the most diverse geometrical shape and constructed of the most diverse materials I have been suggested previously. Such filling bpdies can be inserted into the reaction body elther in a regular arrangement or may be arranged therein irregularly.

It has now been found that a saddle like 310 sha e of the reaction bodies is very suitable an produces a particularly large washing surface. It is particularly advanta eous if these shapes are so selected that t ey are substantially as wide as they are high. It

M has also been found of particular advantage to provide the saddle shaped bodies either with discharging grooves or with holes or with both. For this ur ose they may for examplebe constructed of wire netting. Ac-

92 cording to a further form of construction of the invention the shapes, by means of suitable operations, as for example by slightly pressing together the ends or by the application of suitable projections, ribs or the like, may

also be so shaped that the reaction bodies are prevented from sliding one into the other.

Two or more suitably shaped bodies placed parallel to one another and at a predetermined distance apart may also be assembled tld to form a single unit.

lln the accompanying drawing are illustrated by way of example a few forms of construction of the filling bodies according to the present invention.

Figures 1 to 1 show saddle shaped filling bodies having substantially the same dimensions in length and width. Figure 1 is a" front elevation, Figure 2 a side elevation, Figure 3 a plan and Figure 1 a section on the line A-B of Figure 3.

Figures 5 to 8 show a filling body provided with small projections. Figure 5 shows a front elevation, Figure 6 a side elevation, Figure 7 a plan and Fi re 8 a. section on the line CD of Figure Figures 9 to 12 show a filling body provided with ribs. Figure 9 is a front elevation, Figure 10a side elevation, Figure 11 a plan and Figure 12 a section on theline E-F of Figure 11.

accompanying drawings there is provided a filling bod a having the sha e of a riding saddle. The body is formed rom a circular blank which is folded upon itself in arcuate formation to form the downwardly bent lugs I) and b which correspond to the saddle leaves and reversely folded in a plane at right angles to the first fold to provide twoupwardly bent lugs c and c which correspond to the front pad and rear pads of the saddle seat. Inotlier Words the circular body is subjected to a crosswise reversed compressing or folding.

On the curved inner surface of the constructional forms according to Figs. 1-4, holes are provided at certain distances apart while the constructional forms according to Figures 5-8 show pegs e provided on the saddle face. Figures 9-12 show constructional forms provided with ribs 7 and Figures 13-16 with parallel grooves g. The last named group shows that the primary shape may also be modified in that the lugs bent in crosswise opposite directions are more or less pressed together. Fig. 15 shows how the two lugs c and 0' are relatively com pressed in their center. The filling body according to Figs. 17-20 comprises two single bodies a and a and is formed by uniting gwo single bodies on corresponding flanged aces.

It has been found that filling bodies of the present invention which show as primary shape a crosswise reversed compressed circular area of a form resembling a riding saddle occupy considerably less space and have a much larger working surface. Filling bodies according to the invention have especially the advantage that they do not require to be regularly fitted into the reaction chambers as according to the hitherto usual geometrical molded bodies but may be loosely and irregularly filled in. The attainable reaction surface is almost double and if necessary more than double the surfaces attainable with the usual filling bodies. The very thin structure also permits a very tight and secure fitting in the reaction vessels. Owing w to the peculiar saddle shape the gas streams are continually deflected and always come in contact with irrigated surfacesan action or effect which could only be very inadequately attained with the usual types. For instance,

15 in cylinder bodies the gases rise within the cylinder and occupy the upper positions while the liquid moves on to the lowest positions and is thereby only in inadequate contact with the gas.

go Such saddle shaped reaction bodies may be placed into the chamber in an irregular manner. They form an extremely large surface and, by reason of the constant change in direction in the flow of streams of gas or as liquid, an excellent means for promoting chemical and physical operations such as increasing the speed of reaction on stationary surfaces, extraction and mixing operations between liquids and liquids, between liquids 80 and gases and between gases and gases in the most favourable manner.

The reaction bodies themselves may be constructed of the most diverse material according tochemical and mechanical require- 85 ments and may also be constructed in difierent sizes.

I claim 1. A filling body for reaction and washing towers and the like, formed from a circular 40 blank folded in a crosswise reversed manner to resemble a riding saddle, the height and breadth being substantially equal.

2. A filling body according to claim 1 having apertures therein.

45 3. A filling body according to claim 1 wherein the saddle portion is provided with enlargements.

4. A filling body according to claim 1 wherein the opposed folded portions are so slightly bent towards one another adjacent their outer edges.

5. A filling body for reaction and washing towers and the like comprising a plurality of saddle shaped elements assembled parallel to 55 one another and held at suitable distances apart, the saddle shaped elements forming an integral unit.

In testimony whereof I affix my signature.
