Inassemblingthe-guardt by a belt is which is preferably driven by the 5 the nozzle, the-side 24 thereof may be inserted in the upwardly faced seats of the lugs ll and 81 and then bent slightly until the side 24 is snapped or sprung in the seat of the lug 38. As is apparent, the side 24 of the guard defines a pivot, carried in the lugs ll, 38 and 31 about which pivot the guard may be swung to the position shown in broken lines (Fig. 3) after the latching portions 2] of the guard are sprung from the recesses II by' the handle 28. In the position of the guard shown in broken lines, access is had to the brushv for cleaning the same or for removal thereof from the nozzle. While pivoting of the guard by means of the spaced lugs 35, 36 and 31 is desirable, it will be understood that the lugs 3!, 3i and 31 and the recesses Il may beso formed that the guard is bodily removed from the nozzle when the latches 21 are snapped from their recesses II.

In accordance with this invention, the end members ii of the guard engage the bearings 2| for the brush and, arepreferably resilient so that they bias the bearings 2| inwardly of the nozzle and position the bearings 2| in the sockets 22. If desired, a spring 38 may be seated in the nozzle end wall as shown in Fig. 3 for biasing the bearing 2i outwardly, whereby removal of the bearing 2| from its socket 22 is facilitated when the brush roll II is to be taken from the nozzle l2.

From the foregoing description, it will be apparent that I have provided a guard member of novel construction that may be readily positioned within the nozzle and having improved latching facilities for maintaining the guard in its operating position. Furthermore, the guard functions to maintain the brush roll and its bearing in proper position relative the nozzle. The construction is such that the guard may be readily displaced from its operative position so that the brush is accessible for cleaning or removal. It will be apparentto those skilled in the art, that my improved guard construction may be economically manufactured and assembled to the nozzle.

Vlfhile I have shown my invention in but one.

form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire. therefore, that only such limitations shall be placed thereupon as are imposed by th prior art or as are specifically set forth in the appended claims.

What I claim is:

, 1. In a suction cleaner, the combination of a mule structure having opposed lips for defining ,an inlet opening for dust-laden air, one of said lips being formed with a pair of recesses adiacent the ends thereof, a pair of sockets in the inlet opening at the opposite ends thereof, bearings carried in said sockets, a rotatable brush journalled in said bearings, and a wire frame guard comprising a side member pivoted to the nozzle structure along one of said lips, end members extending from the ends of the side member to the opposite lip and engageable with said bearings to retain the same within said sockets, latch portions connected to the respective end portions and adapted to be sprung into and out of said recesses, a handle portion connected to one of said latch portions and extending exteriorly of the nozzle so that it may be engaged to remove the latch portion from the recess, and guard fingers attached to said side member and extending across said inlet opening.

2. A suction cleaner as set forth in claim 1, wherein the nozzle lip formedwith the recesses is also formed with a ledge on the inner side thereof, said. guard fingers being adapted to rest on said ledge.

3. ma suction. cleaner, the combination of a nozzle having first and second lips and an elongated inlet opening therebetween, a. wire frame guard for said inlet opening, said nozzle being provided with means for retaining one sideof said guard within the male adjacent said first lip and said second lip being formed at its ends with recesses extending longitudinally of the second lip and opening away from said first lip, said guard comprising end members extending between the opposed lips, latch portions extending from the end members longitudinally of the second lip and adapted to be engaged in said recesses, and a handle portion extending longitudinally of the second lip on the exterior of the nozzle and connected at its opposite ends to the respective latch portions.

4. In a suction cleaner, the combination of a nozzle having an inlet opening and first and second opposed lips defining opposite sides of said opening, a rotatable brush disposed in said inlet opening, bearings in which said brush is Journalled, the nomle being provided with sockets or recesses to receive said bearings, a nozzle guard disposed across said inlet opening, said nozzle being provided with means for retaining one side of said guard within the nozzle adjacent-said first lip and with means for detachably securing the opposite side of said .guard to -the nozzle adjacent said second lip, said guard comprising transverse end members engageable with said bearings to retain the same within said sockets orrecesses and guard fingers disposed at spaced intervals between said end members and extending across the inlet opening.
