To whom, it moby concern:

Beitknown that We, SYLvANUs HAROLD S'ro'nrzrus and ARTHR'SAMUEL WOLF, citi zens of the United States, residing at Chamn bershurg, in the county 'ot Franklin and.

State oi Pennsylvania, have invented a new' and useful Dust-Collector, of which the iollowing is a'specification.

. agitating the filtering-bags try with the conveyor-box to loosen the dust.

'This invention relates to dust-collectors'o'f thchalloon ty e, in which a plurality of series oi iiltering-tu es are supported annuiarly in i a rotary membenisaid member being intermittently'rotated to place the series of ltering-hags in succession in registry with a con'- vever-box, mechanism being provided for that are in regisadhering thereto and to cause it to drop into Among the ohjectsoi'v the present invention are to combine the advantages of what is known as a Cyclone dustcollector with those of a dustfcollector in which the air 1s i vcaused to pass through tubular filtering-A durability, and general prior to the passage of the airto the iiltering bags in-a simple and improved manner. Further objects are to promote sim eiiiciency in t ie con struction of the machine. f

` With these and other ends in view, Which will readily vappear as the nature of the -in vvention is better understood, the same consists in the improved construction and novel tion, partly in section,

In yoperation the dust-laden `air may he caused to enter into the casing C through eit'her end oi the flue 3, the' closure 4 having previously been adjusted to deiect the air downwardly into the casing .within whichit whirls about, the heavier dust particles being thrown ,by centrifugal force in the direction of the walls of the casing where they are intercepted by the bailles 5 5 and permitted to the trough 6, containnected with the' e* e oi ing. the screw conveyer 7, whereby it is exj'ielled at one end of the trough. The deilector 5S will serve to intercept the whirling the dustlad'en air deprived ot the heavier and coarser particles will expand laterally within the drums and iind an n outlet through the porous:filtering-bags upon the inner surfaces of which the iine dust particles will be deposited. In the meantime the drums will be rotated intermittently by the pawlandratchet mechanism described, the projections 47 upon the shaft 36 being so disposed that during the time when the drums are in motion the frames, including the meinbers44 and 45, will be elevated so as to present no obstacle to the movement of the drums. As soon as Athe drums become stationary the projections 4.7 become disengaged from cams'i, and the frames will thus be permitted to drop with the cushions 48, impinging upon the crossJoa-rs 1S, with which they are in alincment. The cams 50 upon the main shalt 34, which. latter rotates much more .rapidly than the counter-shaft, will new engage the Wear-plates 49 uponthe cross-bars 45, depressing the latter and simultaneously depressing the crossdiars i8 against the tension oi the supporting-springs lll. As soon as the cams 50 pass out of' engagement with the cross-bars 48 the springs i9 will expand, forcing the crosslbars 18 suddenly in anvoutward direction, and thus stretching the material ol which the tubular iiltering-bags are composed with a sudden snap, which is effective in dislodging the particles of dust upon the inner surfaces ot said bags, causing the dust to drop into the trough 48, where it is disposed of by the spiral conveyor, which carries it to the con* ducting-pipe 33, whereby it is delivered into the discharge end oi" the conveyer-trough 6.

As will be seen from the foregoing description, this improved machine is constructed' with a view to combining within a single structure all the advantages of that class of dust-collectors which are of the well-known lyelonc type and. in which-the separation oi' the dust from the air is eil'ected by centrilugal action, owing to the natural tendency of the heavier particles held in susl l l l l l j ber through the axial aperture. l
