Patented July 20, 1954 T OFFIC SUPPORT, CORD REEL, AND LATCH FOR SUCTION CLEANERS Melvin H. Ripple, Canton, Ohio, assignor to The Hoover Company, North Canton, Ohio, a corporation of Ohio 8 Claims. 1
This invention relates to suction cleaners and more particularly to a tank or canister type cleaner in which suitable cleaning tools may be connected to the motor-ian-filter unit by means of a flexible hose.
More specifically, according to the present invention, a tubular cleaning body is supported for movement over a surface by a pair of supporting skids at one end and by a single, centrally located skid at the other end. All of the skids are upwardly sloped at their forward ends and the pair of rear supporting skids are made reentrant at their rear ends so that the conductor cord for conducting electricity to the power unit may be wound thereon. The single skid at the opposite end of the cleaner is movably attached to the casing so that its free end may be moved away from the casing to form complementary means at the front end of the casing about which the conductor cord may be wound. The single supporting skid is curved downwardly from the body of the casing and has its free end normally positioned against the casing which may be moved away therefrom during the cord winding operation.
According to another feature of the present invention a removable end cap is provided for the casing at the end adjacent the single movably mounted supporting skid, and movement of the skid relative to the casing releases the latch mechanism which latches the end cap to the casing.
According to another feature of the present invention the single skid is movable to one position relative to the casing to permit the winding of the cord about the skids without releasing the end cap latch and is movable to a second position relative to the casing to release the latch.
Other objects and advantages of this invention will become apparent as the description proceeds when taken in connection with the accompanying drawings in which:
Figure 1 is a side View of a tank or canister type cleaner showing the present invention applied thereto;
Figure 2 is an end View of the cleaner of Fig. 1; and
Figure 3 is a cross-sectional view taken on line 3-3 of Fig. 2 looking in the direction of the arrows.
Referring to the drawings the reference numeral I represents the casing of a tank or canister type cleaner supported for movement over a surface by two rear skids II and I2 and a single front skid I3 and is adapted to be carried about by a carrying handle I4.
The exhaust or blower end of the casing I0 is closed by a blower end cap I5 and the suction end is closed by a suction end cap I6.
Encased within the casing I9 is a motor-fanfilter unit 9 well known to the art. In such units the motor-fan unit is positioned adjacent the blower end cap I5 and a filter bag is removably supported adjacent the suction end cap it and is adapted to be periodically removed so that the filter can be cleaned or replaced. One end of a suction hose is adapted to be connected to the female connector I! and its other end attached to any suitable suction cleaning tool whereby the dirt removed by the cleaning tool will be deposited in the filter bag within the casing behind the end cap it. For that reason the suction end cap I6 is so assembled to the casing Ill as to be readily removable therefrom.
The top front of the casing Ill is provided with an upwardly opening socket I8 adapted to receive a lug I9 carried by the end cap iii. The lower edge of the end cap I6 is clamped to the open end of easing I ll by a mechanism to be presently described. A gasket 20 lies between the end cap it and the end ring of the casing it to seal the joint between them.
Referring to Fig. 3 the skid l 3 is pivoted to the bottom central portion of casing I0, to the rear of end cap I6, as at 2!. The skid i3 is biased clockwise by a spring 22 so that its end 23 is normally held against the bottom wall of casing I0 immediately to the rear of end cap it. Inwardly of the pivot 2! the skid I3 is provided with an overhanging flange 2- 5 which, under certain conditions, is adapted to contact the rear end of an end cap latch lever 25, pivoted to the casing ID at 26 and is spring-biased counter-clockwise by a spring 21. At its forward end the latch lever 25 is provided with a hook 28, operatively engageable with a pin 29 suitably carried by the end cap I6 near its bottom edge.
As previously stated, the end 23 of skid i3 is normally held against the bottom wall of the casing It by spring 22. It is also latched in that position by a detent spring 36 having a hump 3i, below which a protuberance 32 on skid i3 is positioned when the end 23 of skid l3 rests against the bottom wall of casing to. Detent spring 313 is also provided with a recess 33 in which the protuberance $2 is positioned in an intermediate position of the skid it in which its end 23 is separated from the bottom wall of casing 10, whereby the loops of the conductor cord 34 may be easily wound beneath the end 23 of skid I3 and into the space between the skid I3 and the bottom wall of the casing I0.
The detent spring is also provided with a hump above which the protuberance 32 is adapted to be positioned when the skid I3 is in latch releasing position. When the skid I3 is moved to such a position its overhanging flange engages the rear end 36 of lever 25 to pivot the lever clockwise and raise the hook 28 from behind the pin 29 and thus release the end cap for removal.
The rear skids H and I2 are reentrant forwardly as shown at 37 (Fig. 1) and also reentrant inwardly at 38 and 39 (Fig. 2) whereby the conductor cord 34 may, in cooperation with skid 53, be supported in its wound condition.
Operation If it is desired to merely wind the cord 34 about, or to unwind the cord 34 from the skids H, 12, and iii, the skid I3 is pulled downwardly to a position in which the protuberance 32 en'- gages in recess 33 whereby the end 23 of the skid will be spaced from the bottom wall of the casing H! to permit the easy looping of cord 34 between the skid it and the casing I0.
If it is desired to release the end cap 46, as when a filter bag needs cleaning or replacement, the skid I3 is turned further counter-clockwise from the dotted line position of Fig. 3, to bring the protuberance behind the hump 35 of spring 38. In such a position the flange 24 of skid l3 will have engaged the end 35 of latch lever 25 to pivot it clockwise and remove the hook 28 from behind the pin 23 and thus release the suction end cap it for removal from the casing it.
While I have shown but a single embodiment of my invention it is to be understood that that embodiment is to be taken as illustrative only and not in a limiting sense. I do not wish to be limited to the particular structure shown and described but to include all equivalent variations thereof except as limited by the scope of the claims.

2. A cleaner as in claim 1 including spring latch means for holding said one end of said front support away from said body during the cord winding operation.
3. In a suction cleaner, an elongated tubular open ended body, a power unit within said body, a conductor cord for conducting electricity to said power unit, an end cap secured to an open end of said body, latch means for detachably securing said end cap to said open end, first supporting means at the end of said body opposite said end cap, second supporting means at the end cap end of said body, said second supporting means being U-shaped and having one leg thereof movably secured to said body so that its free end rests against said body adjacent said end cap whereby said conductor cord may be Wound beneath said second supporting means upon movement of the free end of said second supporting means away from said body and means actuated by movement of the free end of said second supporting means away from said body for releasing said latch means.
