Definitions
- This invention relates; to suction cleaners and more particularly to newand improved dirt filtering facilities therefor; More specifically, one of; the dominant features of the invention is a simple and highly emcient structure for releasably mounting the filter proper in a tanktype suction cleaner.
- Another object isv to provide a unique filter clamping means forasuction cleaner.
- Yet another object is the provision of. a tank cleaner; with afilter clamping arrangement .which isequally effective with a cloth filter bag as well aswith apaper filter nestedwithin a cloth filter.

- the details of the motor and fan construction are; of no particular importance tothe invention, they need not be further described.
- the rearendof the-cleanercasing. is closed. by. an endcap llfi having an exhaust :air opening .for the clean airv discharged by: the-fan and passing through: themotorto cool thesam'e.
- the cleaner casing is: also provided” withv a carrying handle 2 I along its upper side and asnapzacs tion switch 22 for controlling the operation of the motor.
- the filter assembly'and clamping arrangement is located at the forward or inlet end of the cleaner.
- a flanged ring 25' is rigidly secured to the open end of the casing and provides asupport for the cloth filter-supporting ring-16
- the rim of the skirt of this ring is channeled to provide mounting means for-securing ring 21" of a, cloth filter bag 28.
- the innerend of 'this bag has a circular bottom which normally rests against.
- guard wires 29- spaced' forwardly of screen- I85 These guard wires therefore prevent th filter from being drawn into the fan inlet and provide a free flow area for-the air-passing to the fan;

- the end cap for. the inlet endoftheca'sing is generally indicated; at ⁇ ;
- This. cap isash'own as formed of outer and inner: sheet, metal, members 33 and 34 one of which has a downturnedrimifor permanent assembly to inner, member, 3fi',' as by rivets 3.5.

- the paper filter comprises a cylindrical paper bag 42 of a diameter readily receivable through sealing gasket 3
- the bottom is preferably formed by appropriately folding and sealing the inner end in the manner commonly employed in the manufacture of grocery bags.
- the length of the bag is slightly greater than the length of the cloth bag plus the height of mounting ring 26 in order that the paper bag may be seated on the bottom of the cloth bag and project slightly above the top of gasket 3
- the pilot member is generally indicated at 43 and comprises a most important feature of the invention. As shown, this member is formed of plastic material and has the general configuration shown in Figure 1. This may be described as a truncated circular base section from a right cone generated about an elliptical base. posite the hinged side of the end cap, the side wall of the pilot is substantially straight and parallel to the side wall of the cleaner casing.
- top side of the cleaner its diameter gradually decreases from a maximum diameter at the point of attachment to the end cap to a much smaller diameter at its innermost end.
- This shape is extremely useful in facilitating the entry of the pilot into the open end of the filter and in progressively expanding the paper filter outwardly into firm seating contact with gasket 3
- pilot member 43 may have its peripheral rim secured to the end cap in any suitable manner as by rivets, screws or the like.
- is preferably hollow as shown in the drawing to provide greater resiliency and more particularly to provide for a wider range of manufacturing tolerances in the other structural elements associated therewith without, however, decreasing its efiecr Operation
- the operation of the invention is thought quite self-evident from the foregoing description. Let it be assumed that the cleaner is assembled as shown in Figures 1 and 2. The usual flexible hose and dusting tools are connected into coupling 36 and the cleaner is placed in operation by closing the switch 22.
- the cleaner When it becomes desirable to replace the filter, the cleaner is upended onto rear end cap l9 and th toggle clamp 39 is released to allow the end cap 32 to swing to open position as shown in Figure 2. Opening of the end cap completely releases the paper filter bag which can be withdrawn upwardly through the end of the casing. The dirty bag is taken to a place of disposal and discarded. A new filter is then opened and inserted downwardly into the cloth bag. In so doing, the operator expands the top so that the walls lie closely adjacent sealing gasket 3
- the cleaner can be used with the cloth filter without performing any additional or diiferent operation. All that is necessary is to close the end cap and clamp it. Both the upper, outer wall of the pilot and fiat surface 4
- the cleaner is then operated as before and the dirt collects in the cloth filter. When it becomes necessary to remove this dirt, the operator opens the end cap and withdraws mounting ring 26 carrying the cloth filter therewith. After the bag has been emptied, it is re placed and the end cap is closed.
