PHILIP A. G-EIER, OF QLEVELAN'D, OHIO, ASSIGNOR TO THE P. A. GEIER COMP OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
Specification of Letters Patent.
Patented July 5, 1921.
Application filed July 19, 1916. Serial No. 110,222.
To all whom it may concern Be it known that PHILIP A. Game, a citizen of the United States residing at Cleveland, in the county of I yahoga and State'of Ohio, has invented certain new and useful Improvements in Dust-Receptacles for Vacuum Cleaning Apparatus, of which .the following is a specification.
My invention relates to improvements in dust receptacles for vacuum cleamng apparatus, and has for its object the production and that the collected dust and refuse shall remain, as nearly undisturbed as possible,
until the contents of the bag have been emptied. Moreover, it is important that the flow of air shall be relatively as unimpeded as possible. On this account certain forms of valves which have been used hitherto, present the objection that the become filled rearwardly w1th the accumu ated refuse, and thereby restrict the flow of air while causing a constant disturbance of the collected. material, whereby the finer por tions of the dust are caused to bedriven through the fabric. I
My invention contemplatesthe provision in a fabric receptacle of this class, of a partial'diaphragm or partition placed near the entrance to the bag while affording a passageway above said artition of such unobstructed area as wil accommodate the dust-laden air at all times. Said diaphragm affords a retaining wall within the bag.
which prevents the return of the accumulated refuse, and at the same time directs the air currents above such refuse, so that it remains relatively undisturbed within the be or receptacle.
he structural features of m invention me. best be explained and un erstood by ma 'ng reference to the accompanying.
drawings, wherein Figure 1 1s a v1ew1n side elevation, partially broken away, of 'a'dust receptaclec'onstruoted in accordance with my inventlon.
F g. 2 is across-sectional view on line 2-2, Fig. 1. Fig. 3 1s a fragmentary plan view. lug. 4 is another fragmentary vlew illustratlngthe closure means for the open end or top of the bag, and Fig. 5 is aview in side elevatlon, partlally broken away, of a vacuum cleaner and associated dust receptacle.
Throughout the several figures of the drawings, I have employed the same character of reference to indicate similar parts.
Referring to F g. ,1, it is seen that the dust receptacle a, WlllOh is suitably constructed of fabric, has an entrance mouth 11' adapted to fit closely upon the exhaust part or nozzle 6 of a portable vacuum cleaner, such for example, as is shown in Fig. 5. The latter dev1ce, 'as 1s well known in the art, usuall provldes a fan for drawing the dirt and re i use through an inlet nozzle 0, and direct mg t through the outlet nozzle 6 into the fabric dust receptacle. Positioned before said nozzle within the dust receptacle a, is a partial diaphragm or partitiond which may well be a fabric member stitched to the bottom and sides of said receptacle; leaving, however, a space 0 between the upper wall of the receptacle and said diaphragm, of an area equal vto or greater than that of the exhaust nozzle.
In Fig. 1 I have shown by dotted lines, approximately the maximum accumulation of dust, dirt and other refuse within the receptacle, which in a portable cleaner ordinarrly is supported at an angle of about 45 in alinement with and by the handle f of the vacuum cleaner. This is accomplished by a loop or chain f, which is attached to a 011 g, adapted to he slipped over the open en of the fabric receptac' e for holding the same tightly closed until such time as-the contents of the receptacle are to be emptied.
The arrows shownv in Fig. 1 are intended to indicate generally, the course of the dustladen air currents which are directed over the upper edge of the diaphragmand into the free portion of the fabric receptacle a.
, From this the air escapes through the fabric dle ofthe vacuum cleaner, and also, the bottom of the bag is pouched as shown in Fig. 1 to afford a more spacious container for the refuse.
These, with other features explained, are details of construction, which are not essential to my invention, except as defined in and by the accompanying claims.
Having now set forth the preferred embodiment of my invention, 1 claim as new and desire to secure by'Letters Patent, the following 1. In a device of the class described, the combination with a fabric-Walled receptacle, having an inlet opening, of a partial diaphragm positioned therein adjacent to said opening and partitioning the lower ortion of the receptacle from side to side, ut afhaving an inlet and an outlet opening, of a partial diaphragm intermediate of said openings partitioning the lower portion of said receptacle from side to side, substantially as set forth.
In testimony whereof I do now aflix my signature in the presence of two witnesses.
