Description

PA-TENTED JAN. 29, 1907.
. DITTMAR. DUST SEPARATOR FOR CLEANING APPARATUS APPLICATION FILED JUNE 26, 1906.
GUSTAV DITTMAR, OF OFFENBAGH-ON-THE-MAIN, GERMANY.
DUST-SEPARATOR FOR CLEANING APPARATUS- I Specification of Letters Patent.
Patented Jan. 29, 1907.
Application filed June 26,1906. Serial No. 323,507.
To 11 whom, it may 0011,0027: I
Be it known that I, GISTAV DITTMAR, director of the Offenbach Compressed Air Cleaning Company G. M. B. 1]., a subject of the Emperor of Germany, residing in Offenlmch-on-the-Main, in the Empire of Germany, have invented certain new and useful Improvements in and Relating to Dust-Separators for Cleaning Apparatus, (for which application has been made in Germany, dated January 4, 1905,) of which the following is a specification.
The great ractical and hygienic advantages which t e cleaning of fabrics, car ets, and the like by means of a current 0 air possesses have caused this method of cleanmg to be largely employed. I Transportable apparatus are therefore now constructed by means of which the cleaning can be done on the spot. For this it is, however,.necessary that an apparatus should be provided which catches t e dust raised up by the cleaning 0 eration. The dust-filters hitherto 'em ployed for this object have either toolittle surface or they offer too much resistance to the air-current passing through them or they ter hang by means 0 are too complicated.
N ow this invention relates to a dust-filter which, based on the well-known principle of suspended dust-filtering bags, represents an improved arrangement which is not only extremely simple, but also offers the least possible resistance to the air-current and also allows of arapid removal of all the dust collected without special mechanisms or other auxiliaries, as may be seen from the accompanying drawings, in which Figure- 1 is a 10m" 'tudinal and Fig. 2 a cross section, while l igs. 3 and 4 are crosssections of modifications.
This im roved filter consists of a closed vessel a, w ich may eventually be filled with water, provided with adischarge-tap b and an inlet 0 for the dust-laden air. The upper cover or lid of thevessel a, has a number of upwardly-directed tube-sockets (Z, over which the dust-filtering bags e are fixed. The lats'pringsf on an arm arrangement g, which by means of a hand-lever h may be readily moved up and down. This movement has for its object, after each cleaning eriod', to shake down the dust accumulate in the bags, so that it falls downward into the liqhugd-and may thenbe discharged. 1;
therewith, ough'the. tap b.
'of the filter-bags,
latter collapsi Over the whole apparatusa case i, which i also has a filtering action, 1s placed, which casing catches with certainty any very fine dust which may percolate through the pores so that the air passes to the outside fully purified.
In the form of construction shown in Figs. 1 and 2 the filter-bags e are circular in sec tion and then'distributed in oneor more'rows round the apparatus. A still larger filtering- 'surface is obtained, however, if they are given the section of a sector of a circle. They then may be arranged, for instance, in the manner shown in Fig. 3. These bags having the form of a sector of a circle may also, if desired, be again divided and a large increase of the filtering-surface obtained by an arrangement such as shown in Fig. 4.
The cover It, preferably also permeable, of the filtering a aratus in order to make the lil e as far as possible may be placed on supports which consist of two telescoping tubesm and l, which have suflicient frictional engagement with each other so that they will su port the weight of the cover and bags. in this manner after use the filter may be collapsed into a comparatively small space. To increase the shaking action, it is preferable to provide a contactpin n, which engages in a suitable slot in the plate 9 and on the reciprocatin movement of the latter encounters it on bot sides.
I declare that what I claim is A dust-filter for cleaning apparatus, comprising a lower water-contamin vessel having an inlet for admitting dust-la en air to said vessel and a plurality of outlet-openin s in its up er side, a plurality of flexible lterba s c osed at them upper ends and connected y their lower ends to the outlet-openings of said vessel, means connected at the upper ends ofthe bags for elastically supportlng said filterbags, means for shaking sai filter-bags, a cover, and a-flexible case connected to the cover and vessel and surroundin the filter-bags.
Tn witness whereof I have hereunto signed my name, this 19th day of May, 1906, in they presence of two subscribing witnesses.
