VACUUM CLEANING -APPAR ATUS.

To all whom it may concern: I

Be it known that I, FREDERIC B. CooHnA'N, I a citizen of the United States, and a resi-' dent of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Vacuum Cleaning A paratus, of which the followin is a full, clear, act description, re erence being had to the accompanying drawings, forming part of this speci cation.

My nvention relates to apparatus for.

pneumatic or so-called vacuum cleaning, and the object thereof is the provision of a simply constructed, eflicient, portable appa'ratus of that character, suitable for domestic-use.

The invention, of which a preferred form is illustrated in the accompanying drawings, comprises the novel features of construction and arran ement and combination of parts hereinafter es'cribed and specifically pointed out in the claims.

In the drawin Figure 1 isa perspective view of a comp ete apparatus; Fi 2 is a sectional view of the upper part 0 the apparatus, with the cover raised and shown partially in section on the line 2-2, (Fig. 3)

ig. 3 is a vertical section on the line 3-3, (Fig. 1) Fig. 4 is a vertical section on the line 4-4, (mg. 3) Fig. 5 is a plan view of the top of the collectingreceptacle, and Fig.

6 is an external view of the dust separator.

Similar reference characters are employed to designate like parts in all the views.

In the particular form of apparatus illustrated, the operating parts are inclosed in a case or cabinet 1,'which comprises two compartments 2 and 3. In the compartment 2, is mounted a motor 4, which, as shown, is an electric motor adapted for connection with a suitable source of energy by the plug 5, and connections 6. Arotary pump 8, is also mounted in the compartment 2 and its shaft 9, is coupled tothe shaft of the motor. A. fan 10, is mounted on the pump shaft, and the sides of the case 1 are provided with apertures 11, so that the fan 10, will maintain a forced circulation of air through the compartment 'to prevent the motor from becoming overheated.- To the discharge port 12, of the pump 8 is con- Speciflcaticn of Letters Patent.

Application filed July 8, 1909. Serial No. 506,524.

and excal Patented Nov. 15, 1910.

through the partition se arating the compartments 2 and 3, an its end projects over a pan 15, in the compartment 3, int/0 which any oil or dirt which may pass through the pump will be discharged. The suction port of the ump is connected with a stand pipe 16, which extends upwardly to the top of the case 1, and at its upper end is provided with a flange 17, which is provided with a circumferential channel, in which is held a asket 18, of resilient material, such as so rubber.

A dust receptacle and separator are removably mounted in the compartment 3 and comprise a cylindrical vessel 20, preferably of metal, stiifened by corrugations 21, and divided into two compartments by a partition 22, which extends partially across the vessel near its up er end and is then extend ed upwardly to t e top of the vessel. The to of the vessel 20, and of the diametriextending artition'22, are provided wit channeled anges-24 and 25,-in which is held a gasket 26, of soft rubber or other suitable material. Theseflanges are preferably formed of sheet metal bent into the propler shape to hold the gaskets firmly.

T e dust separator consists of a perforated tube 30, covered loosely with a tubular bag 31, preferably of loosely woven textile material, which will obstruct dust and dirt but will permit the passage of air without'materiallyreducing the capacity of the pump. The bag 31, may be held on the tube 30 by a clamping band 32. The up er end of the tube 30 is provided with a t readed flange 33, which screws into a threaded bushing in the partition 22. The flange 33 is formed with finger pieces 34, which permit the convenient screwing and unscrewing of the parts. By this construction, a tightjoint is secured and yet the tube and itsenvelop may be readily removed bodily from the apparatus for cleaning, when necessary.

The case 1, is provided with a cover 35, which serves the purpose of closing the case and sealing and connecting pneumatically -the various elements of the apparatus a]- nectedna tube 14, which extends upwardly ready described. In one edge'of the cover is secured a'thimble 37, which receives the end of the suction hose 38, to which the cleaning A channel" r duct 44, is formed in the cover--35 and at one end, through the open-- ing 45, communicates with the compartment 46 of the ve'ssel20, while at the othgrend,

throu h the opening 47, itcommunicates with t e standpipe 16. The cover 35 is preferably hin ed-at one side of the case and releasable fiver-catches 49, are provided at the opposite side so that when the cover is closed, its under side will be held down firmly on the gaskets 18 and 26, which will form hermetically sealed joints at these points.

The dust receptacle or vessel 20, may be provided with lugs 50, which enter recesses in its su porting partition, enabling it to be accurate y placed to register with the openings in the cover 35. Similar lugs may also be provided for the drip pan 15.

Access to the compartment 2, containing the motor and pump, is had by means of a door 51. Handles 52, are attached 'to the sides of the case 1, by means of which it can be lifted and carried from place to place.

I-n. ordcr to operate the apparatus, the

cover is fastened in position by the catches 49, the cleaning tool 39, is connected by means of a flexible tube 38, (which is provided with a suitable coupling for that purpose), with thimble 37. The motor 4, is then started to operate the pump 8, which will create a. partial vacuum in the-pipe 16, duct 44, receptacle 20, suction hose.38 and cleaning tool 39. If now the cleaning tool be applied to the surface or object to be cleaned, the dust and dirt therefrom will be drawn through the tool and suction hose into the receptacle 20, where it will be deposited, the air passing on through the separator 31, tube 30, duct 44, pipe 16, pump 8 and out through the discharge pipe 14. VVhen-the cleaning operationis completed, the motor is stopped, the cover 35 is unfastened and lifted, the receptacle 20 is removed from the compartment 3, and emptied. In case it should be desired to clean the surface of the which the tube is replaced and the apparatus 1 is ready for another operation.

As will be observed, the apparatus is compact,relatively light and may be readily replace, thus adapting it combination with a dust receptacle and separator, comprising'a vessel lprovided with a partition extendln partial y across the upper portion thereo dividing the vessel into two com artments, of a dust filter and a support t ereforsuspended from said partition and a cover rovided with air inlet and outlet passages w ich are brought into operative relation to establish communication besages communicating with said vessel on opposite sides of said partition when the cover is closed, and a gasket between said cover and said flanges.

3. In avacuum cleaning apparatus, the combination of an inclosing case, a dust receptacle and separator therein comprisinga vessel having two compartments, a dust filter comprlsing a support and a foraminous covering suspended in one of said compartments and opening into the other compartment, and a cover for said case provided with air inlet and outlet passages which are brought into operative relation to establish communication between said compartments through the filter when the cover is closed.

4. In a vacuum cleaning apparatus, the combination of an inclosing case, a suction producing device and operating means therefor located in the case, a suction pipe fixed inthe case, one end of which is connected with the suction producing device and the other end of .which opens at the top of the case, adustseparator within the case, comprising a ves'sel'having two compartments, a dust filters'uspended in one of said compartments and opening into the other of said compartments, and a cover for said case provided with air inlet and outlet passages, said.

inlet passage being broughtinto operative relation with one of said compartments, and said outlet passage being brought into operative,

connection at one end with'the other of said compartments and at the other end with the suction pipe,by,the closing of the cover.
