v The present invention relates/ to suction cleaners in general and more particularly to height-adjusting means for the no zzle of a suction cleaner. Specifically the invention comprises the provision of means for adjusting the position of the front supporting wheels of the suction cleaner relative to the cleaner itself .thereby serving to vary the position of the nozzle lips relative to the surface coverin v The object o? the present invention is lto provide new and novel means for adjusting the nozzle height of a suction cleaner. A second object is to provide a simplified construction by vwhich the front supporting wheels of the suction cleaner may be adjusted relative to the cleaner itself. A still further object of the present invention is the provision of a manually adjustable nozzle height determining construction for a suction cleaner which is of simple construction and easily manufactured. Other and more' specific objects will appear upon reading the following specication and taking into consideration the drawings annexed thereto.

Referring now to the drawings In Figure 1 is disclosed a side view of a suction cleaner embodying the present invention, with certain parts broken away.

l Figure 2 discloses a bottom View upon the line 2--2 of Figure 1.

y. Figure 3 is a section upon the'line" 3-3 of Figure 2.

Figures 4 and 5 are views in of the supporting brackets.

Referring now to Figure 1 in particular, a suction cleaner is disclosed which comprises the usual parts including a motor casing 1, a fan casing 2, a nozzle casing 3 which is made v integrally with fan casing 2, dust bag 4 which is attached to the exhaust outlet of fan chamber 2 which is not shown, the handle member 5i which is pivotally attached to the motor casing 1 in order that the cleaner may be moved about upon the surface covering,. a rear supporting wheel 6 which is rotatably but non-adjustably secured to the motor lcasing 1, and front supporting wheels 7,7 which are adjustable relative to the perspective cleaner in a manner which comprises the present invention.`

- Pivotally mounted, as is clearlyshown in` Figure 2, to the side walls 8, 8 ofthe casting comprising the nozzle and fan casing 2 and 3 are the arms .or brackets 9 and 10 which are secured in' place by vmeans of hollow ,rivets 11, 11. The supporting arm 9 comj ing axle' 14 which extends transversely of the cleaner and immediately behind the suction nozzle and also immediately below the side walls 8, 8, aforedescribed. At the pivoted end of body portion 12 of bracket 9 a straight arm portion 15 extends at right ang1es.-v The rear face of arm 15 is parallel to the transversely extending'portion of the wall 8 upon that slde'of the cleaner and is adapted to be contacted by the screw-threaded adjusting member 16 which' is seated within an interalsly threaded enlarged portion 17 of the wa The bracket orarm 10,*see Figure which I is pivoted to the remaining wall 8 comprises merely a straight body portion which is pro- C vided with ott-set curved arms 18, 18 which form a cylindrical seat for the end of the-axle .14 opposite to that enclosed by the arms 13, 13 of bracket'9. In bot-h brackets 9 and 10, the arms which form the seat for the axle 14 are stamped from the body portion of the bracket'and are of sufficient length and rigidity to 'preventany looseness or play of the axle 14 therein. The supporting wheels 7, 7 are mounted upon the opposite ends ofthe axle 14 immediately outside the side walls 8,

a 8 and are secured relativeto the axle by means of securing screws 19, 19 as shown in Figure 2.

^Substantially midwaybetween the walls 8,"` i

8 is aspring member 20 which is secured by means of a screw 21 to the wall of the fan casing 2. The extended armsy of` the spring 20 contact the underside of the axle 14 and serve at all times to exert an upward force on that' member which tends to pivot the a plate or pointer 22 is provided ,which brackets 9 and 10 about their supporting pivots until such pivotal movement is limite y contact of the arm 15 with the adjusting member 16.

In order that the adjustment of the nozzle ofthe cleaner relative to the surface covering may be readily observed by the operator,

nFigure, 1, the exact adjustment of the suction cleaner nozzle relative to the surface covering. The plate and finger being fixedly car-` ried by the shaft 14 and bracket 9 is moved as they arer pivoted4 v and so indicates the changes in nozzle position. l

To adjust 'the nozzle height of' a suction cleaner embodyin `thepresent invention, it is only necessary or tle operator to manually rotate the I: nernber 16. If it is desired. to raise the nozzle the member 16 lwill be advanced through the wall 8 causing' the bracket 9 to bepivoted about its pivot point 11 through-the force exerted upon the contacting arm 1,5. Because of the substantially y rigid relation of the brackets 9 and 10 and the axle 14.-, the bracket 10 is also pivoted 'about its pivot point and the supporting wheels 7, 7 are uniformly lowered relative to the cleaner pro 'er thereby raising thesuction nozzle from t e surface covering. I f on,

the other hand it is desired tolower the suction cleaner llnozzle `-relative to the surface coveringthe adjusting member .16 is retracted through the wall 8 permitting the coil spring 20 to exert a rotating force directly upon the shaft 14, and so brackets 9 and 10, which is limited only by the contact of the arm 15 with member 16. The degree of adjustment 1s apparent at all times to theoperator by means of the pointer or -inger which indi# cates, by its position relative'tothe inarks upon the nozzle casing, the relation of the suction cleaner nozzle to the covering.

I claim: 1. In a suction cleaner height adjusting construction, spaced' supporting. Wheels, ya

common shaft extended between said wheels,

pivoted brackets connecting said shaft toa cleaner casing at spaced points, said brackets being each provided with a seat for said ,sha-ft' extendedy in the direction ofthe shafts length to prevent looseness, resilient means contacting said shaft and urging said lWheels in one direction, and manually adjustable means comprising a threaded memberincontact with one of said brackets and adapted to move said wheels against the force exerted by said spring.

I 2. 'In a suction cleaner heighty adjusting construction, spacedl supporting .Wheel's, al

commonl shaft rotatably supporting said wheels; spaced brackets exten ed perpendicularly to said shaft and pivoted to a casing, each bracket being providedvvith a' seat formed of ispaced-folded-deformed sections extending parallel to and closely enclosing said shaft, and means to pivot one of said brackets to effect the adjustment of said said brackets being' unconnected ex-v wheels, cept by said shaft.b
