vto

In this form, the floor tool 30 has the same socket 36, and the bracket 34a is secured at one end to the leaf spring 35, which is retained by the screw 21.

The roller 3| is mounted on an arm 31a which is formed with a portion 34h bent to align with the bracket 34a. The arm 31a and portion 34h' constitute a carriage which is movably mounted on the bracket 34a by means of a hinge 42. An adjusting element 43, on the member 34h, engages a coacting element 44 on the bracket 34a, the latter being preferably in the form of a tongue formed on the bracket 34a and projecting beyond the hinge 42. The adjusting element may be a screw, threaded through a sleeve 45 secured to the member 34b. The coacting elements 43 and 44 carry the weight of the cleaner from the bracket 34a to the roller carriage 34h, 31a.

If the member 34h is considered as part of the bracket, then the adjustment is accomplished by varying the angular relation of the hinged members of` the bracket, by adjusting means spanning the hinge. This form of the invention also possesses the advantage that the change in adjustment does not vary the range of possible depression below normal riding position. The clearance between the hinge 42 and the spring 35 is unaiected by a change in adjustment.

, I claim as my invention:

1. In a suction cleaner, a oor tool,'a mounting including a bracket movably attached to the 4oor tool and having a projecting portion, a rollerl carrying part movably connected solely to said projecting portion, a roller journalled on -said part, and adjusting means connecting said part to the bracket, serving to carry the weight of the cleaner from the bracket to said part. and a spring interposed between the bracket and the floor tool and resiliently carrying the weight of the oor tool to the bracket, whereby the floor tool may be manually depressedbelow any one of a series of normal riding positions determined by the'balance between the weight of the cleaner and the tension'in said spring when iiexed under said weight, and the position of adjustment of said part.

2. In a suction cleaner, a floor tool, a pair of mountings, each including a bracket movably attached to the Iioor tool one at either end of the iioor tool, projecting beyond said end, and having a projecting vertical portion,`a carriage slidable on vsaid vertical portion, a roller journalled on said carriage, and'adjusting means connecting said carriage to the bracket, serving to carry the weight of the cleaner from the bracket to the carriage, and to provide adjustment of the height of the carriage relative to the bracket, and a spring interposed between the bracket and the floor tool and resiliently carrying the weightof the floor tool to the bracket, whereby the oor tool may be manually depressed below any one of a series of normal riding positions determined by the balance between the weight of the cleaner and the tension in said spring when flexed under said weight, and the position of adjustment of said carriage.

3,. In a suctionv cleaner, a iioor tool, a roller mounting including a. bracket movably attached to" he oor tool, a'roller carrying part hinged to the bracket, for swinging movement relative to said bracket, a roller journalled on said part near the swinging end thereof, adjusting means acting between, said bracket and said part, carrying the weight of the cleaner from the bracket to said part, and a spring interposed between the bracket and the oor tool and resiliently carrying the weight of the oor tool to the bracket, whereby the oor tool may be manually depressed below any one of a series of normal riding positions determined by the balance between the weight of the cleaner and the tension in said spring when flexed under said weight, and the position of adjustment of said part.

4. In a suction cleaner, a oor tool, a mounting 10 including a bracket movably attached to the iloor tool, a roller carrying part movably connected solely to the bracket, a roller journalled on said part, and adjusting means acting between said part and the bracket, serving to carry the weight 15 of the cleaner from the bracket to said part, and a spring interposed between the bracket and the floor tool and resiliently carrying the weight of the iloor tool to the bracket, whereby the floor tool may be manually depressed below any one of 2o a series of normal riding positions determined by the balance between the weight of the cleaner and the tension in said spring when flexed under said weight, and the position of adjustment of said part.

5. In a suction cleaner, a floor tool, a mounting including a bracket one end of whichis fulcrumed, relative to the oor tool, so as to allow the bracket to swing vertically relative to the iioor tool, a roller carrying part movably connected to the 30 other end of the bracket,'a roller journalled on said part,iadjusting means acting between said part and the bracket, serving to carry the weight of the cleaner from the bracket to said part, and a spring interposed between the bracket and the 35 floor tool and resiliently carrying the weight of the ilor tool to the bracket, whereby the floor tool may be manually depressed below any one of a series ofVv normal riding positions determined by the balance between the weight of the cleaner 4o and the tension in said spring when flexed under said weight, and theposition of adjustment of said part.

6. In a suction cleaner, a oor tool, a mounting including a bracket movably attached to the floor 45 tool and having a projecting vertical portion, a carriage slidable on said vertical portion, a roller journalled on said carriage, and adjusting means connecting said carriage to the bracket, serving to carry the weight of the cleaner from the brack- 50 et to the carriage, and to provide adjustment of the height of the carriage relative to the bracket, and a spring interposed between the bracket and the floor tool and resiliently carrying the weight of the Hoor tool to the bracket, whereby the floor 55 tool may befmanually depressed below any one of a series of normal riding -positions determined by the balance between the weight of the cleaner and the tension in said spring when iexed under said weight, and the position of adjustment of 00 said carriage.

7. In a suction cleaner, a oor tool, a mounting attached thereto comprising a bracket having a projecting non-horizontal portion, a carriage movably mounted on said portion for up and 65 down adjustment relative to theybracket, a roller journalled on said carriage, andadjusting means connecting said carriage to the bracket, serving to carry the Weight of the cleaner from the bracket to the carriage, and to provide adjustment 70 of the height of the carriage relative to the bracket, and a spring interposed between the bracket and the floor tool and resiliently carrying the weight of the floor tool to the bracket, whereby the oor tool may be manually depressed be- 1| nexed under said weight, and the position of adjustment of aald'carriale. i

8. In a suction cleaner. a door tool, a mountin: includlns a bracket one end of which is ful- 4 me bracket lo .wma vertically relative erumed relative to tbe door tool. ao aato allow noot tool. a roller l other end o! the bracket, 'tor swinzlns movement relative w said bracket. a roller l part near the end thereof means acting between said bracket and said part, earryinl the weight o! the cleaner from the bracket, whereby the floor tool may be manually depressed below any one of a series o! normal ridlns positions determined by the balance between the weight of the cleaner and the tension lnl said sprms and the positiva o! adjustment of said part.
