SEPARATING-TANK FOE VACUUM CLEANING AP?ARATUS.

Specification of Letters Patent.

Patented Nov. 16, 1%(39.

Application filed July 11, 1908. Serial No. 443,128.

To all whom it may concern:

Bent known that I, DANIEL Fooan'rnof the city of Ottawa, in the county of Carleton, Province of Ontario, Canada, have in vented certain new and useful Improvements in Separating-Tanks for Vacuum Cleaning Apparatus, of which the followlng is a specification.

My invention-relates to improvements in separating tanks for vacuum cleaning apparatus, and the objects of my invention are to provide certain improvements in detail, as

given hereinafter in the specification and.

claim.

In the draw1ngs ,Figure 1 is a side view an enlarged sectional detail of the vhead of the vacuum separating-tank.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the dust collecting chamber into which extends the screening chamber B which is cylindrical and provided with a head (1 having an aperture 6 therein, which is'internally screw-threaded and engaged by an externally screw-threaded cylindrical. memher a, the top of which is engaged by a ring (Z, which supports the screening chamber within the dust dollect-ing chamber. A hand: hole '10 is provided in the dust collecting chamber for the removal of dirt. The screen ing chamber may be formed of any material pervious to air, but impervious to dust. I.

prefer to form it of a layer of coarse screen netting covered by a layer of fine brass wire cloth, in turn covered with muslin or other cloth. The coarse netting, which may be about three-eighths of an inch mesh, serves to hold the fine wire cloth, which may be about sixty threads to the inch, in shape.

C is a suitable form of pump, preferably double-acting, and having pipes e, f, g and 7!. extending from the exnausting ports thereof,

t0 a single pipe i, which connects with a cylindrical member 7' .which has screwthreaded engagement with a connecting member 7c, the lower end of which has screwthreaded engagement with a ring Z which is connected through the medium of a packing ring m to the cylindrical member 0. The

'near the bottom for the removal pump discharges through a conductor n, the extremity of which is provided with a valve 0 and this conductor is connected by a pipe 7) with the pipe 2', a valve q being inserted in the pipe 79 and a similar valve 9 in the piped between the point of connection of the pipe 7) and that of the four pipes c, f, gfand h.

The dust collecting chamber is placed in communication with the vacuum nozzle, by.

means of a suitable conducting pipe .9 which extends therein. Below the valve r a T- coupling t is secured having a conducting pipe 11 adapted to communicate with the air but controlled by a valve '2).

In ordinary operation, the valves 0 and T 'will be opened, and the valves Q and. '0 closed.

The pump being operated in the ordinary manner, will create a vacuum in the screeningichamber to suck the air therein, the dust drawn out of the carpet, or other article being cleaned, being separated by the screen and remaining in the dust collecting chamber.

It will be observed that the air laden with dust discharges downwardly into the dust collecting chamber and part will settle on the bottom, whilethe air is drawn upward into the vacuum separatingchamber.

If through the continuous operation the screen should become covered with dust and operates unsatisfactorily, the valves 0 and r are closed, and the valves 9' and o are opened, and the air current produced by the pump reversed in operation. .This will force air through the conductors a, p and 2' into the vacuum chamber and through the screen, cleaning the same, the air for this operation being drawn in through the conducting pipe u and the conducting pipes c, f, ,7

It will thus be seen that l. have devised an exceedingly cheap and simple form of screening tank, which embodies all the advantages which it was the object of the invention to attain.

What I claim as ni entice is;

An improved. vacuum separating tank comprising in combina b vertically extending cylindrical casing having a hand-hole of'dirt, and having an internally screwthreadd aperture at the top thereof, an externally screwthreeded cylindrical member engaging the aperture,-eeyiincirieel screen extending within the chamber, a ring cqnnecting the screen with the cylindrical member, a vacuum suction pipe connected to said cylindrical memvher and adapted to exhaust the interior of the chamber, and, a smflil downwardly dishand in the presenceof two Witnesses.
