-The present invention relates-to suction cleanersandmorep ar-ticularly to a new and-improved handle control in-a suction cleaner.

Itis an object of the inventiontoprovidea newand improved suctionlcleaner. Another ob- .iect t ro i a s m a wdurame handle .:con trol. A; further object is to providea handle ,control-permitting freg rnovement .of the handle ineach of-the working range adjustmentsand ;resilientlyl .-prevent movement of thelhandle ,ianothenadiusted,worlging range. Other objects and advantages of the invention-will be' apparent from the following specification and drawings wherein:

Figure 2 is a perspective vlewof 'thel'ever means attachedto the cleaner handle; and

Figure-3 isa-sectionalong :the line 3-3 of Figure}. he, in e tiqn hereind sc ss c ris sasl a bag l5 and a motor housing IS. The body I5 is propelled over the surface being cleaned by a handle I! provided with a pair of bail arms I8, only one of which is shown, disposed on opposite sides of the motor housing l6 and are pivotally mounted on a rod l9 supported in the housing I6. An unshown torsion spring is disposed about the rod Hi to counterbalance the weight of the handle H.

The handle control mechanism comprises a member secured to the housing It by rivets 2| and is provided with a flange 22 having spaced seats or recesses 23, 24 and 25 representing different handle positions defined by projections 26, 21, 28 and 29.

A lever 3| has a part formed in substantially U-shape to provide walls 33 and 34 which are disposed on opposite sides of the bail arm I8 and are pivotally mounted thereon by a rivet 35. A portion 36 is cut out of the U-shaped part of the lever 3| and forms a continuation of the wall 33 and has rigidly mounted therein a pin 31 on which is rotatably mounted a detent roller 38 adapted to move between the projections 26, 21, 28 and 29. the lever wall 33 and abuts the ed e 4| of the bail arm I8 to limit counterclockwise movement of the lever, as viewed in Figure 1, and prevent the detent 38 from engaging the surface of the 4 Claims.

If it isgdesire'df'to rriove the oilgingirang de lfined'f between trons ;2l'an earn v I the I8 to maintain the roller detent 38 out of contact with the recessed surface of the seat 24. In maintaining the roller detent 38 out of contact with the surface of the recessed seat 24 the handle moves freely in the working range between the projections 21 and 28.

If it is desired to move the handle I! to the lower range of adjustment defined between the projections 28 and 29 a force is exerted on the handle to cause the detent 38 to ride over the projection 28 into the seat 25 but out of contact with the surface thereof. In order to raise the handle ll, an upward force is exerted thereon to move the roller detent 38 into the desired working range. The projections 26, 29 are contoured to limit respectively the high and low positions of the handle [1.

While I have shown and described but a single modification of my invention, it is to be understood that this modification is to be taken as illustrative only and not in a limiting sense. I do not wish to be limited to the particular structures shown and described, but to include all equivalent variations thereof except as limited by the scope of the claims.

I claim:

1. In a suction cleaner, a body, a handle pivotally mounted on said body, means having recessed seats 23, 24 and 2 An arm 42 a spaced recessed portions defined by projections representing different extents of adjusted handle movement between adjacent projections, lever means having detent means engageable with said projections to limit the range of adjusted handle movement with respect to said body, said projections and lever means being supported on said handle and body, stop means to prevent engagement of said detent means with the surface of said recessed portions between adjacent projections during movement of said handle between such projections, and resilient means enaging said lever means to resiliently prevent movement of said detent means beyond said projections unless a force is exerted on said handle to move said detent means over a projection into another range of adjusted handle position.

2. In a suction cleaner, a body, a handle pivotally mounted on saidbody, means on said body I having spaced recessed portions defined by projections representing different extents of adjusted handle movement between adjacent projections, lever means pivotally mounted on said handle and having detent means 'engageable with said projections to limit the range of adjusted handle movement with respect to said body, stop means on said lever means engaging said handle to prevent engagement of said resilient means engaging said lever means to resiliently prevent movement of said detent means beyond said projections unless a force is V exerted on said handle to move said detent means over a projection into another range Of-f projections representing different extents of ad-;'

justed handle movement between adjacent projections, lever means'having portions on opposite sides of said handle for pivotal connection thereto, detent means on said lever means ensmite detent means with said recessed portions, and

gageable with said projections to limit the range? of adjusted handle movement with respect to said body, stop means on said lever mean engageable with said handle to limit movement of said detent means in one direction, and resilient means engaging said lever means to prevent movement of said detent means in another direction beyond said projections unless a force is exerted on said rigid handle, said handle due to its rigid structure transmitting said applied force to said lever means to move said detent means over a projection into another range of adjusted handle position.

4. In a suction cleaner, a body, a handle pivotally mounted on said body, means on said body having spaced recessed portions defined by projections representing difierent extents of adjusted handle movement between adjacent projections, lever means having portions on opposite sides of said handle for pivotal connection thereto, detent means on said lever means engageable with said projections to limit the range of adjusted handle movement with respect to said body, stop means on said lever means engaging said handle to prevent said detent means from engaging said recessed portions, and resilient means arranged about the handle pivot and engaging said lever mean to resiliently prevent movement of said detent means beyond said projections unless a force is exerted on said handle to move said detent means over a projection into another range of adjusted handle position.
