DUST-COLLECTOR.-

SPBCIPICATION forming part of Letters Patent No. 361,711, dated April 26, 1887.

Application filed August 31. 1886. Serial No. 212.284.

T0 at whom it may concern:

Be it known that we, AUGUST CHRISTIAN NAGEL and BEINHoLD HERMANN, KAEMP, both citizens of the free state of Hamburg, and ADOLF WILHELM FRANZ GEORG LINNEN- BRiiGGE, a subject of the King of Prussia, all three residing in the city of Hamburg,German Empire, have invented new and useful Improvements in Dust-Collectors, (for which we have received a patent in Italy, No. 157,Vol. XXXIX, dated April 7, 1886,) of which the following is a specification.

Our invention relates to dust-collectors operating by means of a current of air produced by suction, and in which the filtering-surfaces are cleaned by a back-draft; and theimprovements consist in the particular means employed for creating the said back-draft and for shaking the filtering-surfaces.

On the annexed sheet of drawings, Figure 1 represents, in sectional elevation, a dust-collector constructed according to our invention. Fig. 2 is a side View thereof; Fig. 3,.a horizontal section on line a a, Fig. 1; and Fig. 4,a top view, with a portion in section, according to line b 1). Figs. 5, 6, and 7 represent details to a larger scale.

The apparatus consists of a chest divided by the horizontal partition-wall 2 into the horizontal wall of the compartment 4, so as to be in permanent communication with the outer air. From the said cylinder branches off a hollow arm, 10, having at its lower side an opening adapted to register with one or more cells, the edges of the said opening, which are flanged, being in sliding contact with the partition-wall 2. By means of this arm and the (No model.) Patented in Italy April 7, 1886, No. XXXIX, 157.

cylinder 9 a communication is established between the outer air and the cells, with which the arm registers at the time. The upper rim of the cylinder 9 is provided on its periphery with teeth, with which engages a pawl, 19, Fig. 4-, pivoted to a bevel-wheel, 18, that is driven by a pinion, 17 shaft 15, and pulley 16. The rotation of the said pulley will thus produce a slow intermittent rotation of the cylinder 9 with its arm 10. Moreover, these parts are so arranged in respect to each other that, if the inside width of the arm corresponds to that of a single cell, the arm during its time of repose between two strokes of the pawl'19 will register exactly with one of the cells, and that at every stroke of the pawl it will be pushed over the following cell. If the arm has a width corresponding to two cells, it may at every impulsion be advanced by one or by two cells, as may be preferred, and thus the like for three or more cells.

When the apparatus is in operation and dust-laden air is drawn by the exhauster into the compartment 3, the air alone passes from the latter through the filtering-surfaces of all the cells not communicating with the arm 10 into the said cells, and thence into the compartment 4, and out by the tube 5, while the dust is retained by the said surfaces. In respect to the cell or cells 1- being in communication by means of the arm 10 and the cylinder 9 with the outer air, the eXhauster Will, on the contrary, operate to draw air from the outside of the apparatus through the cylinder and its arm into the said cell or cells, and thence through the filtering-surfaces of the same into the compartment 3, where it mixes with the air entering at A. An inverted current or back-draft is thus produced in the latter case, with the effect of blowing off the outer side of the filtering-surfaces the dust adhering thereto. According as the arm 10 moves forward,

the cells are in this manner cleaned in succession.

The means for shaking the cells at the same time they are subjected to the action of the back-draft consists in a hammer arranged to rotate with the cylinder 9, and operated to strike against the cell or cells which are in communication with the arm 10. As is shown in the drawings, the hammer is formed by a bell-crank lever, 11, with hammer-head 12, the said lever being pivoted to the bottom of the cylinder 9, and actuated by a cam, 20, on the shaft 15, through the medium of a yoke, 14, guiding itself on the said shaft, and of a rod, 13, passing centrally through the bottom of cylinder-9, and connected by a swiveling joint to the yoke 14. I

The dust collecting in the compartment 3 may be discharged from the same by any suitable meanseas, for instance, by a creeper, 22, which conveys it toward an aperture provided with a self-closing flap-valve, 23,

We claim as our invention 1. In a dust-collector, the combination,with the chest comprising compartments 3 and 4 and the apertured partition-wall 2, said com.- partments communicating, respectively, with the dust-producing machine and an exhauster, of the filtering-cells 1, arranged in a circle and inserted with their open upper ends into apertures of the wall 2,\the rotating cylinder 9, communicating with the outer air and having the hollow arm 10, adapted to slide with its lower open side upon the wall 2 and to register with one or more cells, and means for rotating the cylinder 9 and arm 10,substantially as and for the'purpose described.

2. The combination,with the compartments 3 and 4, partition-wall 2, filtering-cells 1, rotating cylinder 9, and hollow arm 10, arranged substantially as described, of the hammer 11 12, pivoted to the cylinder 9, and adapted to strike against the cell or cells communicating with the atmosphere, and mechanism for actuating the same, as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
