DUST-CO LLECTO R.

SPECIFICATION forming part of Letters Patent No. 468,935, dated February 16, 1892.

Application filed June 9, 1886.

To aZZ whom it may concern:

Be it known that I, ORVILLE M. MORSE, of Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dust-Collectors, of which the following is a specification.

This invention relates to that class of dustcollectors in which a separating-chamber is employed, which causes the dust=laden air to assume a whirling or gyrating motion, whereby the dust particles are thrown to the "periphery of the whirling body of air.

The object of the present invention is to construct a simple machine which, while be- I 5 ing applicable to various uses, is especially adapted to separate large dust-such, for instance, as sawdust, shavings, dive-from the air.

My invention consists to that end of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved dustcollector. Fig. 2 is a horizontal section in line 00 to, Fig. 1.

structions of the separating-case.

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

A represents the separating case or chamber, provided at its upper end with a tangential spout a, through which the dust-laden air enters the case.

Brepresents the head or cover which closes 3 5 the upper end of the case and which is provided with a central opening I), through which the purified air escapes from the machine.

C is a tubular guard secured to the head 13, in the opening 1) thereof, and depending in the chamber A, preferably below the lower edge of the spout a. The separating-case A is provided with spiral deflectors d, inclined from the upper or inlet end to the lower or discharge end of the case. These deflectors may be formed by corrugating the case spirally, as represented in Fig. 1, or by securing downwardly-inclined or tapering spiral deflectors d to the inner side of a cylindrical shell (1 as represented in Fig. 3, or bysecur- Figs. 3 and t are fragmentary vertical sections showing modified con- Seri No.204,686- (NomodeL) ing spiral flanges cl to the inner side of the shell (P, as represented in Fig. 4.

E represents the bottom or head, which closes the lower end of the separating-case A and which is provided near its periphery with an opening e, through which the dust. is discharged from the case into a spout f. The latter maybe provided with a suitable slide 9.

It represents an air-pipe extending from the spout f to the center of the bottom E, Where it communicates with the chamber A, so that 6c an excessive volume of airdischarged through the opening 6 can return to the chamber A by the pipe h. The dust laden air enters the chamber A and assumes in the same a whirling or gyrating motion, which causes the dust particles to seek the periphery of the whirling body of air and crowds them against the peripheral wall of the chamber A. The spiral deflectors arranged on the inner side of this wall cause the dust particles to move downwardly to the bottom E, from which they are discharged through the opening 6. The purified air, escapes upwardly through the tubular guard O.

I claim as my invention- 1. In a dust-collector, a circular separatingchamber provided with spiral deflectors, a peripheral dust-discharge at one end, an airinlet spout connected tangentially with the opposite end, and a central discharge for the purified air, substantially as set forth.

- 2. ha dust-collector, acircularseparatingchamber A, provided with an air-inlet spout,

a dust-discharge, and spiral deflectors arranged between the air-inlet spout, located at one end of the separating-chamber, and the dust-discharge, located at its opposite end, substantially as set forth.

3. In a dust-collector, a circular separatingchamber provided with spiral corrugations, 0 substantially as set forth.

Witness my hand this 5th day of June, 1886.
