My invention relates to improvements in gaging the yoke of the caster at its lower end 6o carpet-sweepers; and its Objectis to simplify and the bottom of the pintle-socket at its and reduce the cost of construction and to upper end. Said brush-shaft is journaled in provide the same with certain new and use hangers J, which are flexible in adirection at i 5 ful features hereinafter more fully described, right angles to the axis of the brush-shaft,

What I claim s-d l. In a carpet-sweeper, a brush-shaft journaled in laterally-flexible hangers and driving-wheels at one side of said brush-shaft journaled on a rod passing through inclined openings in the case, in combination with a caster-wheel-on the side of the case opposite said driving-wheels and a spring engaging said caster-wheel and adapted to be depressed on the downward movement of the case when the latter is being lowered, as described.

- 2. In a carpet-sweeper,ahandle-socket having a ring at its lower end surrounding an elastic bushing, through which passes a pivotbolt, angle-plates at each side of said ring secured to the case, having depressions at their upper sides, and projections on the sides of said socket engaging said depressions, substantially as described.

3. In a carpet-sweeper, a push-pin having a T-head, connecting-rods pivoted to the same and to the dust-pans near the pivots of said pans, and a lifting-spring engaging the end of said push-pin, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
