CARPET SWEEPER Filed March 5, 1934 4 ff /f f5 l INVENIORS FRANK ROBINSON N CHARLES :..BETTS Byu/wllw@ ATTORNEYS Patented Mar. 26, t 17935 UNITED `STATES PATENT CARPET SWEEPER Frank Robinson'and rCharles Idenden Betts,

In Great Britain June l8, 1933 4 Claims. (Cl. 15-41) This invention relates to carpet sweepers of the type provided with oor or track wheels which also operate to effect the driving of a rotary brush comprised in the sweeper by frictional contact with rollers provided at the ends of the brush According to this invention, in order to obviate' the disadvantage of the'known arrangement of the wheel supporting rods wherein they pass across the space close to the dust'receiving pans into which dust is thrown by the brush, the said rods are bent or cranked at parts thereof within the casing so as to avoid causing obstruction of the space across which dust is thrown from the brush into the said pans.
In the accompanying drawing: A
Figure 1 shows a side view in vertical section transverse to the brush spindle and wheel supporting rods, of a carpet sweeper in accordance with this invention. g
Figure 2 shows a part of the carpet sweeper in section on the line Figure 1.
As shown in this drawing, the ends 1 of rods or wires which support oor or track wheels 2 pass through holes 3 of larger diameter formed in the sides 4 of the casing and each rod or wire intermediate of the parts extending through the holes or slots 3, is bent to provide parts la lying close to the sides of the casing on the inside thereof and a part 1b extending across the casing from side to side close to the top or cover 4a of the casing. Thus the parts of the, rods within the casing occupy positions close to theinside Walls thereof, allowing larger or deeper dust collecting pans to be used. A similar result can be attained by 4arranging the parts 1b,'for example, near to the end walls 4b. f
The parts 1b of each rod or Wire are supported by springs' 5 or resilient arms, one adjacent to each side of the casing, and the ends 1 ofthe rods or wires at each side of the casing are urged the outside of the casing, the said pins extending into axial holes in the spindle 8.
A bar 11 secured to a block 12 provided for carrying a combi?, for cleaning the brush, or otherwise 'mounted within the casing, is optionally f provided near each end of the part 1b to limit.
downward movement of the rod or wire. Thus the movements of the parts 1b are confined within limits whilst allowing sufficient movementv thereof as required when the ends 1 of the rods..
or wires move to different positions in the slots or holes 3 by reason of variable yielding `of the springs 5, 6 under variations of the load imposed thereon by or throughthe casing.
We claim:
1. In a carpet sweeper comprising a casing, a
rod having an intermediate part thereof extending across the casing from side to side near the top thereof, resilient arms supporting the said intermediate part, terminal parts of the said rod extendingoutside the casing out of alignment with the intermediate part, and track wheels mounted on the ends of said rods.
2. In a carpet sweeper comprising a casing, a
rod having an intermediate part thereof extend.- ing across the casing from .side to side near the top thereof, parts extending close to ther lateral Walls of the` casing, parts extending outside the Casing, track wheels mounted on the parts of the rod outside the casing, resilient arms supporting the said intermediate part, and a bar for limiting the vmovement of the intermediate part of the said rod.
3. In a carpet sweeper comprising a casing, a rod having the endsthereof extending through holes of larger diameter than the rod formed in the lateral walls of the said casing, a part of the OFFICE-,
said rod extending close'to the said lateral walls, e
an intermediate part of the rod extending across the casing near to the top thereof, a second rod arranged similarly to the `above mentioned rod,
on the said rods exterior to the casing.
4. In a carpet sweeper comprising a casing, a
Vrod having the ends thereof extending through holes of larger `diameter than the rod` formed in the lateral walls of the said casing, `a part ofthe said rod extending close vto the said lateral walls, an intermediatev part of the'rod extending across the casing near to the top thereof, resilient CHARLES IDENDE'N 'Bs'i'rs v
