Claims.

The present invention relates to suction cleaners and more particularly to supporting the dirtcollecting bag on the cleaner while the dirt is being removed from the bag.

An object of the invention is to provide a new and improved suction cleaner. Another object is to provide a suction cleaner wherein the dirt collecting bag is supported on the cleaner while the dirt is being removed from the bag. A further object is to provide a suction cleaner wherein the dirt bag is pivoted into dirt-receiving and dirt-emptying positions while attached to the cleaner casing. Other objects and advantages of the invention will be apparent from the following specification and drawings, wherein:

Figure 1 is a broken longitudinal section of a suction cleaner;

Figure 2 is a section along the line 2-2 of Figure 1;

Figure 3 is a section along line 3-3 of Figure l, and

Figure 4 is an elevation of the suction cleaner showing the bag moved into bag-emptying position.

The embodiment of the invention herein disclosed comprises a suction cleaner having an elongated substantially rectangular casing 8 supported from the floor by skids 9 and is provided with a bottom wall H], a rear wall II and opposed side walls l2 and i3 which extend from the top of the rear wall Ii downwardly to the front end I4 of the bottom wall Hi to define an elongated inclined opening l5. Forming part of the casing is a cover I 3 having a front wall 11, a top wall i8 and opposed side walls is and 20, the latter being complementary to the defining edge of the inclined opening iii. A handle is mounted on the cover l6 for carrying the cleaner.

An opening 2i in the cover front wall I1 is closed by an end cap 22 pivoted to the cover front wall ll is indicated at 23 and is held in closed position by a latch 24. The end cap 22 is biased by a spring 25 to swing the end cap 180 degrees to open position as shown in Figure 4 when the latch 24 is released. Rigidly mounted on the end cap 22 is a conduit for detachably receiving one end of an unshown hose having a cleaning nozzle for engagement with the surface to be cleaned in a manner well known in the art.

The cover I3 is pivoted to the bottom wall in by means of a hinge 21 and is held in closed position by a latch 28 on the rear wall II and cover top wall IS. The cover front.wall l'l projects opening 2! in the cover front wall I! lies substantially in the plane of thesurface supporting the cleaner. If desired, ,the pivot 29 may be spaced a greater distance rearwardly from the cover front wall l'l so that when the cover It is moved to the bag-emptying position shown in Figure 4, the cover front wall I! will raise the front end of the casing from the floor to insure that the cover front wall I! will lie substantially in the plane of the floor.

Supported on the cover front wall are two substantially U-shaped rods 30, 30' which extend rearwardly to support a dirt-filtering bag 3! of paper or cloth or other suitable dirt-filtering material. The forward end 32 of the bag is removably attached by a clamp 33 to a collar 34 forming part of a front wall l1, and the opening 2| in the latter is slightly smaller than the crosssectional area of the dirt bag 31.

The suction creating means comprises a motor having a shaft 41 on which is rigidly mounted a double-stagesuction creating fan having movable blades 43, 43 at opposite sides of a stationary,

partition 44, the latter forming part of a fan housing 45 secured to the motor housing by screws 46. .A fan exhaust conduit 41 is removably attached to the fan housing 45 by screws 48 and projects through an opening 49 in the casing side wall l3 to detachably receive an unshown hose and cleaning nozzle when it is desired to remove the dirt by blowing air on the surface to be cleaned. Openings 50 are provided in the motor housing for the passage of filtered air to cool the motor, and the fan housing 45 has openings 5| for the passage of filtered air into the interiorof the fan housing and thence through the exhaust conduit 41. The motor and fan housings are supported on a pair of brackets 52 removably mounted on the casing bottom wall ID by screws 53, The motor and fan may be inserted as a unit inside the cleaner casing through the inclined opening i5 and secured in position transversely of the cleaner casing and rearwardly of the bag 3! by the screws 53.

In operation, assume the cleaner parts are in the position shown in Figure 1, and the unshown cleaning nozzle in contact with. the surface to be cleaned. Operation of the suction creating means causes the dirt removed from the surface being cleaned to pass through the unshown nozzle and hose through the opening 2| into the dirt bag aeeaaoe -3l where the dirt is collected, and the air passes through the bag and is filtered and enters the openings 50 to cool the motor and thence through the fan housing and the exhaust conduit 41, and the filtered air also passes through the openings 5| into the fan housing and thence through the exhaust conduit 41.

When it is desired to remove the accumulated dirt from the bag 3|, the latch 24 is released and the spring 35 swings the end caps 22 through an arc of 180 degrees to expose the opening 2| to the bag. Thereafter the latch'28 is released and the cover It is rotated substantially 90 degrees to shift the bag and the cover to the bag-emptying position shown in Figure 4. When the bag 3| is in bag-cleaning position the forward end I! of the cover It lies substantially in the plane of the supporting surface to form a substantially airtight seal therebetween so that when the dirt drops out of the bag ll through the opening 2| onto the supporting surface, very little dust will escape. If desired a paper may be placed upon the supporting surface to receive the dirt as it is removed from the bag and thereafter the removed dirt maybe wrapped in the paper and the latter thrown away. Due to the arrangement of the bag mouth forwardly of the pivot point 29 of the bag 3|, the dirt drops out of the bag as the latter is gradually moved downwardly to its bag receiving position. when the bag 3| is in bag-emptyported in said body for collecting the dirt removed from the surface being cleaned, an opening in said body for entrance of dirt to said filter, a cover, means movably connecting said cover to said cleaner body for movement of said cover to opened and closed positions with respect to said dirt entrance opening, said filter collecting the dirt thereon when said coveris in closed position, said cover being movable with respect to said body to uncover said dirt entrance opening for engagement of the latter with the supp rting suring position a portion of the bag is exposed'and may be grasped by the operator and shaken to loosen the dirt from the bag.
