The suction end o'f- 'the casings clos y a.removable.e nd..cap leproviued with which is secured to a circular flange 2 I, the latter 40 defining the inlet and outlet to the bag it and being secured to the casing by unshown screws. The flange 2| is provided with a flat face 22 which forms the extreme end of the casing NJ and is adapted to lie flat on a supporting surface when the front end cap M is removed and the cleaner is upended vertically into bag-cleaning position. The bag [8 is adapted to be vibrated to dislodge foreign material therefrom by e, bag-shaking device indicated generally at 50 as described in the application of Louis E. Segesman, Serial No. 599,147, filed June 13, 1945, now Patent No. 2,498,098. Casing I0 is slidably supported in its horizontal position on the supporting surface by a pair of skids 23 attached to the cleaner casing Ii], and a carrying handle 'side wane 31 into the side walls r2452 ,of a

the "side walls 31-'3l ofa .U-shapedlinkflil to form a stationary pivot for the forward end 39 of the link 38. The rear end 40 of the'li'nk 38 isprovided- -with a pin ilextending through its U' slraped latch lever. 13, and the pin ll forms a movable pivot for the latch lever 8. The latch lever 43 extends from the point Mi forwardly of endby cap llhavinganj'outlet port l2 adapted 25 the fextr-eme .front end 22-of the casing [Band 1= terminates in a-hook 45 which engages the front the fronhface 46 of theend cap during movement. of 'the' latch lever 43' to its unlocked position.

Thestationaryxpivot 35 and movable pivot 4| are offcenter with respect to each other, the

movablepivot ii being closerxtothe casing l8. Atorsion spring 48 is arranged about the stationary. pivot- 36 .and when the latch is released tends' toepivot the rearend. dgiof the link 38 c1ockwise ;a'sviewed. in Figure 2, and is. limited in such movement by end 39 abutting lthfiizrcas ing I0. About the movable pivot il is a torsion spring 5! which functions when the latch is released to move the hook 45 of the latch lever 43 counterclockwise as viewed in Figure 2 to the position indicated in dotted lines and the latch lever 43 is resiliently held in this position by the torsion spring 5|. In released position the latch lever 43 is disposed away from the front face 22 of the casing I0 so that the latter may be upended to its vertical bag cleaning position and the front face 22 placed upon the supporting surface without the necessity of the operator manually moving the latch lever 43 away from the supporting surface or the lever 43 interfering with placin the front end 22 of the casing directly upon the supporting surface.

In operation, the dirt-laden air is drawn through a suitable dusting tool unit connected to the inlet port l4 in the front end cap I3 and passes into the filter bag I8 which removes the suspended foreign material, and the cleaned air passes through the fan chamber and then through the exhaust port I2 in the rear end cap II into the surrounding atmosphere.

When it is desired to clean the bag l8 the operator lifts the rear end 60 of the latch lever 43 and thus moves the movable pivot 4| and link 38,

about the stationary pivot 36 and causes the inclined face 4'! of the hook 45 to move forwardly and toward the center of the front end cap 13. After the movable pivot 4| has passed beyond the center of the stationary pivot 36 the operator removes his hand from the end 60 of the latch lever 43 and the torsion spring 48 then is free to exert its force to pivot the link 38 about the stationary pivot 36 in a clockwise direction as viewed in Figure 2 until the forward end 39 of the link 38 rests upon the casing In, as indicated in dotted lines in Figure 2. During clockwise movement of the link 38 and after the operator applied lifting force is removed from the rear end 60 of the latch lever 43 the torsion spring pivots the latch lever 43 counterclockwise about the movable pivot 4! as viewed in Figure 2 causing the hook 45 to disengage the front end cap l3 and to move to an angular position with respect to the casing 10 and rearwardly of the front end wall 22, as shown in dotted lines in Figure 2. Thereafter the front upper end of the end cap pivots outwardly to permit the downwardly extending lip 25 on the underside thereof to disengage its socket 26.

The operator then upends the cleaner casing to its bag cleaning position with the endplate 22 lying fiush upon a supporting surface which is preferably provided with a paper to receive the dirt passing through the open end 2| of the bag I8. With the cleaner casing so positioned, the bagshaking mechanism described in the aforesaid Louis E. Segesman Patent No. 2,498,098, is operated to repeatedly vibrate the bag [8 to dislodge the dirt which thereupon falls downwardly through the opening 2! to collect upon the underlying paper or supporting surface.

After the bag has been cleaned, the operator tilts the cleaner back to its horizontal position on the supporting skids 23 and inserts the lip 25 of the end cap l3 into the pocket 26 and then grasps the rear end 60 of the latch lever 43 and moves the latter about the movable pivot 4| whereby the hook 45 engages the front end cap [3, and thereafter the rear end of the lever 43 is depressed to pivot the latter and the link 38 about the stationary pivot 36 to lock the end cap to the casing.

From the foregoing it will be noted that when the latch is unlocked the lever 43 is automatically shifted to an angular position with respect to the casing l0 and is clear of the front end Wall 22 of the casing, and is held in such position so that the casing may be upended to bag cleaning position without the operator manually holding or removing the lever 43 away from the front wall 22 as the latter is placed upon the supporting surface.

I claim: In a suction cleaner, a casing, means defining an opening at one end of said casing, a removable cap for said opening and projecting beyond said one end, a dirt collecting filter in said casing exposed to said end opening for emptying the collected dirt therethrough, said end opening means when said cap is removed adapted to rest upon a surface to support said casing thereon in upended filter cleaning position, latch mechanism mounted on said casing and including a lever having hook means at one end movable into and out of engagement with a portion of said end cap to removably attach the latter to said casing one end, link means connected respectively to said lever and said casing by a displaceable pivot and a stationary pivot, resilient means biasing said lever for rotation about said displaceable pivot to a position inwardly of said casing from said one end and to maintain said hook means in said position when said casing is upended on said end opening means into said filter cleaning position, said hook means and end cap portion when in said engagement being arranged with respect to said pivots to prevent said operation of said biasing means, and means at the opposite end of said lever for receiving a force to move said hook means about said stationary pivot out of said engagement with said end cap portion for operation of said resilient means to rotate said hook means to said position inwardly of said casing one end.
