PNEUMATIC DUST GOLLECTOR.

Specification of Letters Patent. Application filed July 20,- 1907. Seria1 No; 384,705.

to a portab e t pe of machine of such size and capacity t at it may be conveniently used in places where it is impractical or undesirable to adopt the larger types of dust collectors now in use; and'one which may be eflectively operated by suction apparatus of low pressure type suitable for domestic'use. The primary object of my invention is to apparatus of this character in particles will be separated from the finer by centrifu al action. v

- A furt er object .of'my invention is to pro vide means for conveniently supportin the. flexible hose usually employed with'suc ap-' aratus. 1

With the above. andother objects in view,

and construction offarts hereinafter described, and illustrate in the accompanying drawings in which Figure 1 is a side elevation of my im roved roken away. Fig. .2 is a central longitu a1 sec-- 7 tion taken on a plane at right angles to that 5 5 lv I 1 wall f the dust collector.

of Fig.- 1. I Fig. 3 is a transverse section talzen on the line 3-3. of Fig. 2. Fig. 4 is a transverse section taken on the line 4-4 of Referring tojtheidrawings indetail, my

improved machine comprises a base 1, moui1ted on casters orlrollers2. Ada ted to fit within the base 1 are two removabe dust boxes or drawers 3 and 4, onejof which-is adapted to receive the'finer articles, and the other the coarsenparticles o dust.

I Above the dust boxes is arranged a plat-.

form. 5, and extending la-tform are a pluralty 0 posts 7 (shown in ig.-3). *These osts suppprt at their upper 8, to w 'chis secure 7 the 5, and embracing the post ufpwardly from this.

ablycomprises concentrically arranged 'cyllinders 11 and 12 formed of coarse wire gauze, between which is arram ed a packing 13,- of cotton waste-"or other similar material. It will be seen that a wall, thus constructed, will permit of air seeping through readily, but will effectually prevent the escape of dust.

. Disposed adjacent the platform 5 is an an nular rame 14 on which rests the bottom, 15,

t will be observe "that the chamber 18 is substantially of the shape of an inverted cone, and is provided at its upper or larger.

end with a vertical portion 19, over-the top of which extends a cover plate25.. This vcover plate is provided, centrally, with an opening ormed with aidepending,-annular flange 26, around the same. 5 By reference to Fig; 3 it will be. seen that the wall 19 of the chamber 18 is extended for approximately half a turn, with a spiral configuration, thus forming between itself and the inner wall 21, a conduit 20. 'As shown Figs. 1 and 2, a flue 22 extends from this conduit 20 t0- the fan casing 23. This fan casing is mounted on the top 9 of the ma- ;chine, and the fan is directly connected to any suitable motor 24, refefably, electric. A exiblehose 27 on the fan casmg,h'as one suction nozzle 28."

Surrounding the securedfisto the platform 5,.1s an annular trough. 6, clearly-shown in Fllg. .2 T1118 trough is designed to support t e hose 2 7, when, as'shown in Fig. 1, the hose {1s disconnected from the fan casing; and coiledv around the dust collector; when the machine is not in use. .Inthis pos1tionalso,'the ofv dustcollector casing, and v 100 end fitted onto a nipple 2 3 and is provided at its other end with any suitable formof theh'ose, carrying' the suction nozzle, is sup ported by nieansofaspring clip 29 secured to the top 9, of the casing. I I Owi g to th f t that-the arrangement 18 such .asto necessitate the mounting of the fan-andmotor near one edge of. thedusticase,

and owing to the further fact that these parts are usually quite heavy, I provide, in order to facilitate the ready moving of the apparatus from place to place, handles 10, secured to diametrically opposite sides of the casing, and located so that they are in line with the axis of the fan and motor. This arrangement will prevent the uneven movement of the ap aratus which would result were the hand es placed in any other manner.

The operation of my improved dust col lector is as follows: The dust-laden air drawn in through the hose 27 passes throu h the fan casing 23, through the flue 22, and intothe conduit 20. It will be observed by reference to Fig. 3, that this conduit 20 is tangentially arranged in relation to the chamber 18, and therefore, when the current of air is dis charged into the chamber 18 from this'conduit, a whirlin 0r cyclonic motion is imarted to the a1r contained in the chamber. %wing to this cyclonic action, the heavier and lar er particles of dust are thrown outwardly y centrifugal force, and, striking the walls of the chamber slide down the same and are discharged through the lower end 17of the chamber, into the dust box 4.. At the same time, owing to the shape of the chamber 18 and the manner in which the current of air is delivered therto, a vortex is created along the axis of the chamber 18, and the air, laden with the finer particles of dust, rises u wardly in a stream and escapes through tile 0 ening 26 into the-dust collecting casing.

he air then gradually seeps out through the walls of this casing, while the fine dust is deposited within the same, and settling down, collects upon the hopper-shaped bottom 15. In this connectionit 18 to be noted that the dust casing is comparatively l'ar e, so that the air may readily diffuse throug the walls thereof, and the pressure in the casing always remain low.

After using the apparatus for a given lengthof time it Wlll be observed that, by slightly tilting the machine toward the left (Fig. 2), and gently ta ping or jarring the casing, the fine dust Wil e caused to slide down the sloping sides of the bottom 15,- and be discharged through the opening 16, into the dust box 3.

The purpose of the depending flange 26 is to prevent the larger particles of dust from being driven directly out of the chamber 18 before the whirling motion is imparted to them. The said flange acts as a baffle late for the air current, and prevents any irect.

dust collecting apparatus, and one which readily lends itself to domestic service, and it is thought that the numerous advantages of my improved machine will be readily appreciated by those skilled in the art.

What I claim is 1. In a pneumatic dust collecting apparatus, a cylindrical casing, having porous walls, means for delivering dust laden air thereto, and a hopper-shaped bottom for said casing, havin its discharge opening disposed eccentrical y of said casing, whereby, by tilting said casing, the collected dust may becaused to gravitate toward said opening.
