My invention relates to castors, and has among its objects and advantages the provision of an improved castor mounting for buckets or the like.

In the accompanying drawing:

Fig. 1 is a perspective view of a bucket showing my invention applied thereto;

Fig. 2 is a sectional view along the line 2-2 of Fig. I;

Fig. 3 is a bottom plan view taken from the position indicated by lines 3-3 of Fig. 2;

Fig. 4 is a top plan view taken from the position indicated by lines 4-4 of Fig. 2;

Fig. 5 is a perspective view of the castor unit; and

Fig. 6 is a sectional view of a difierent form.

In the embodiment selected to illustrate my invention, I make use of sheet metal cut to provide a plate or floor l t, a narrower part 12 bent to provide a trough l4, and a lip l6 extending upwardly beyond the level of the floor Hi. In shaping the trough I 4 the metal is bent along a straight line at I8, while the lip- I6 is provided with a slight curvature having its concave side facing the straight wall 20 of the trough.

My trough is arranged to receive the bead or flange 22 associated with the bucket 24 and common to buckets and all sheet metal receptacles.

In operation, the device is connected with the bucket by merely slipping the trough l4 over the bead or flange 22. At this time the bead or flange will engage the straight wall 20 at the points 26 (see Fig. 4), while the lip IE will engage the opposite side of the bead.

The relation between the bead and the lip [6 will depend upon the curvature of the bead. However, the three point contact established between the trough and the bead 22 provides a frictional connection tending to hold the device firmly in assembled relation with the bucket 24. Of course, the trough I4 may be widened or narrowed to provide compensation for structural variations in different flange and bead constructions.

The depth of the trough l4 accommodates beads or flanges of the largest proportions. When the device is associated with the bucket 24, its bottom 28 will rest upon the floor I0, which floor is supported upon a castor 30. In Fig. 1 I illustrate three castor units as being associated with the bucket, which units provide a castor support for the bucket permitting the latter to be pushed along the floor.

In Fig. 2 the castor 30 comprises the usual wheel 32 mounted for rotation between walls 34 comprising integral parts of the bearing plate 36 having ball races 38 formed therein. This plate is arranged in spaced relation with a companion plate 40 having frictional relation with the balls 42 lying Within the races 38 and operatively connected with the plate 36 through the medium 5 of a rivet 44. This rivet is positioned loosely within the opening in the plate 36 to permit rotary movement of the plate relative to the plate 40. I prefer to connect the plate 40 with the floor ID by spot-welding, as indicated at 46 in Fig. 3. 19

To facilitate positioning of the bead or flange 22 within the trough I4, I bend the lip IE to provide an outwardly projecting end 48. This end tends to guide the bead 22 into the trough l4 and provides a grip part permitting easy disconnection of the trough from the bead. My invention functions equally well with buckets having large or small beads or flanges.

In Fig. 6 I illustrate a slightly difierent form in which the floor 50 associated with the trough 52 performs an additional'function as a substitute for the plate 40. The floor is depressed at 54 to permit the riveted part 56 of the rivet 58 to lie within the recess below the surface of the floor 50. This construction operates in the same way and is cheaper to manufacture.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A castor mounting for buckets having a bead around the bottom, comprising a load plate for supporting the bottom of the bucket, a trough carried by the load plate, the bottom of said trough being ofiset below the plane of the load plate, to position the load plate for engagement with the bottom of the bucket, said trough having one side wall contacting the head at a plu- 4o rality of spaced apart points, and a second wall having one point of contact with the opposite side of the bead, to be frictionally connected therewith.

2. A castor mounting for buckets having a bead around the bottom, comprising a load plate having supporting relation with the bottom of the bucket, said load plate having a portion bent out of its normal plane and shaped to provide a trough for frictionally receiving the bead, the bottom of said trough being offset below the plane of the ment with the bottom of the bucket.
