DUST=COLLECTOFL SPECIFICATION forming part of Letters Patent No. 370,021, dated September 13, 1887.

Original application filed June 9, 1836, Serial No, 204,684.

To all whom it may concern:

Be it known that I, ORviLLE M. Monsn, of the city of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in Dust-Collectors, of

which the following is a specification.

This invention relates to a dust-collector Which is provided with a conical or tapering separatingchamber, into which the dustladen 1o air is delivered from a tangential inlet-spout, whereby the air is caused to assume a whirling or gyrating motion in the separating-chamber. This motion of the air causes the solid particles to pass into the outer layer of the I5 whirling body of air and to be deposited against the inner surface of the separating-chamber,

which latter is provided with a dischargeopening for the separated dust and an escapeopening for the purified air. A dust-collector 2o ot' this kind is described and claimed in an application for patent led by me March 31, 1886, Serial No. 197,307. It is found in practice that the tine and light dust follows the tapering Wall oi' the separating-chamber toward the small end thereof, while larger bulky particles of the sizeof a kernel of grain and larger move under the-intluence of centrifugal force in an opposite direction toward the large end of the separating-chamber.

The object of my present invention is to constructthedust-collectorinsuchmannerthatthe large solid particles are freely discharged from the separating-chamber; and my invention consists to that end of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying` drawings, Figure 1 is a sectional elevation ol' inyimproved dust-collector. Fig. 2 is a top plan view thereof on a to a reduced scale. Fig. 3 is a horizontal section in line ai x, Fig. 1, on a reduced scale. Fig. 4t is a longitudinal vertical section through the dust-discharge passage at the large end of the separating-chamber.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the Inachine, and B the conical or tapering separating-chamber Supported in the same.

Divided and this application filed August 22, 1887. Serial No. 247.540. (No model.)

C represents the spout through which the 5o dust-laden airenters the large end ol" the chamber B in a tangential direction.

d represents the dischargeopeniug for the fine or light dust, formed at the apex or small end ofthe tapering chamber B. v

.E represents the cover or head which closes the large end ofthe chamber B, and which is provided with a large central opening, c, through Which the purified air escapes from the machine.

f is a tubular guard secured to the head E in the opening e.

g represents the discharge-passage for the large or heavy dust or material, arranged at the periphery of the large end ofthe tapering separating-chamber. rlhis passage is preferably formed by a recess cut into the under side of the head E, as represented in Figs. 1 and 4, and extending outwardly from the interior of the chamber B to the outer side of the head, as represented by dotted lines in Fig. 2. The outer end of the passage g connects with a descending spout, G, by Which the heavy material is conducted to a suitable receptacle.

' The dust-laden air enters the tapering chamber E in a tangential direction and assumes a whirling or gyrating motion in the same, forming a vortex in which the dust particles are quickly driven to the periphery of the whirling body of air, thereby freeing the inner portion of the whirling body of air from dust. The tine and light dust particles move in helical lines of gradually-decreasing radius toward the small end of the tapering chamber B and escape finally through the opening d. The large and heavyparticles move in helical lines of gradually-increasing radius toward the large end of the tapering chamber B and escape finally through the passage g. The air which has been freed from dust escapes through the gr; opening e, which is protected by the depending tubular guard f. The latter prevents dust particles, which have just entered the chamber B by the spout C, from passing into thc outgoing current of purified air and escaping 95 with the same.

I do not wish to claim in this application the combination of the tubular guard with e 3vo,oz1

the separating-chamber, as this invention is claimed ,in an application led by me June 9, 1886, Serial N o. 204,684, of which the present application is a subdivision.

I claimas my invention- 1. In a dust-collector, a tapering separatingchamber providedwith an external inlet-spout entering the case tangentially, a dischargeopening for the escape of the heavy solid matter, arranged at the large end of the separating-case, and a central air-exit, substantially as set forth.

2. In a dust-collector, a tapering separatingchamber provided with an external inlet-spout entering the case tangentially, a dischargeopening at the large end of the case for the escape of the heavy solid matter, a dischargeopening for the light dust, and a-central airexit, substantially as set forth.

3. In a dust-collector, a tapering separatingcase provided at its apex with an opening for the escape of thelight material and at its large end with a central opening for the escape of the purified air and a peripheral opening for the escape ofthe heavy material, and means whereby the air is caused to whirl in the separating-case, substantially as set forth.

4. The combination, With the conical separating-chamber B, having a discharge-opening, d, at its apex, and a tangential air-inlet spout, C, of a head, E, provided With a central opening, e, and a recessed peripheral opening, g, substantially as set forth.

Witness my hand this 17th day of August, 1887.
