CARPET SWEEPER HOUSING AND HNDLE Filed OClZ. 31, 1933 Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE 2,057,181- lomu'nrr SWEEPER HosING AND HANDLE Nathan P. Bloom, Louisville, Ky. Application October 31, 1933, Serial No. 696,111

6 Claims.

This invention relates to improvements in hand operated carpet sweepers and has more particular reference to an advanced means for attaching the operating handle to the sweeper housing.

The principal object of this invention is to eliminate the conventional objectionable everinterfering and now unnecessary bail or yoke and its associated exterior bearings and trap-pings.

Another object is to provide improved means for balancing the outboard .weight of the operat ing handle and to simultaneously provide a steadying spring pressure from the handle to the housing.

A further object is to interiorly locate the necessary associated members for balancing the operating handle instead of the conventional external equipment which has uniformly proven to be objectionable.

A still further object is to co-ordinate related 20 parts into sub-assemblies to expedite manufacture and to provide efficient and simple means for service when necessary.

Other objects and advantages of my novel structure and combinations are hereinafter set forth in detail and will be apparent to persons skilled in the carpet sweeper art, to their advantages insofar as they are patentably novel, I will claim the same as hereinafter set forth.

Drawing Figure 1 is a fragmentary plan View of the central section of the carpet sweeper housing which primarily depicts the top trim plate. The subsequent drawing is on a larger scale. Fig. 2 is a side elevational view of the trim plate and its companion interiorly disposed member designated as a saddle plate. This figure shows a central section removed to disclose their assembled mechanical relations to each other; also a cross section of the handle shaft which extends through the side walls of each plate and further a portion of the operating handle and other co-related parts which are dealt with hereinafter. Fig. 3 is a side elevational view of the trim plate. Fig. 4 is a side elevational View of the saddle plate. Fig. 5 is a cross sectional view of a portion of the full length of the sweeper housing as seen from the line 5, 5 in Fig. 1 and is arranged to disclose the handle shaft and its central section which is cut away to show one method of attaching the operating handle to same.

Structure Numeral I0 indicates an arched stamping and 55 is termed the trim plate. It is equipped with a channel or well Illa throughout almost its entire u length and a series of decorative lines Illb` on its face B. These are parallel to the well andy terminate in marginal corners. As indicated in Figs. 1 and -5 this plate closes a transverse opening in the arched top II of the housing and it is secured to the sloping dust compartment members'I2 by means of bolts I3 which also incidentally similarly secure saddle I4 and the outer vends of handle balancing springs I5c, the latter being completely enclosed within the dust compartment. The relation and assembly of these parts are shown in Fig. 2 while Fig. 5 shows how the central section of the saddle embraces the handleshaft I 5 which is located in the dust compartment and is journaledinbearings II,V fixed into end walls I'I of the sweeper housing.

1 lShaft I5 is cross drilled to receive operating or propelling handle I8, handle positioning lug I9 and a rod, the diametrically disposed ends of which form handle balancing spring arms I5a, I5b to which are pivotally attached the inner ends of springs I5c which are bent to a 90 angle for engagement therewith.

In Figs. 2 and 5 handle I8 is shown in full lines to be arrested in the vertical position by rounded lug I9 engaging and straining the arched hollow spring Illa which is secured to saddle I4 by rivet Mb. As the handle is moved to other positions, this lug cams its way from spring I4 while on the return, the reverse procedure takes place and results in a lai-,ching action which holds the handle in a yielding vertical position. Again as the operating handle travels away from the vertical position counterbalancing springs I5c function to prevent the outboard weight of the handle from falling in response to gravity. The result is a balancing action by reason of force being transmitted to and from these springs through shaft I5 and arms I5a, I5b. Handle I8 is also Shown in a dotted position disposed at 90 from the vertical, the lug I9 and arms I5a, I5b together with the inner ends of the springs I5c are also shown by dotted lines in the position which they will be forced to assume when the handle has been displaced to the horizontal.

Scope A study of this invention and the structure employed to disclose same, as for the purpose of evasion, may suggest obvious modifications, rearrangements, eliminations and substitutions without departing from the spirit of the invention, therefore, I wish to be limited only by the accompanying claims.

I claim:

1. A carpet sweeper having a dust compartment provided with a top and end walls, said top having a centrally disposed opening; bearings disposed in said end walls, a shaft mounted in said bearings and extending through said compartment adjacent said opening, and an operating handle extending into said opening and attached to said shaft.

2. A carpet sweeper having a dust compartment provided with a top `and end walls, said top having a centrally disposed opening, a plate secured to said top and fashioned to form Aa.

channel disposed in said opening; bearings lo cated in said end walls, a shaft mounted in said bearings and extending across said compartment and said channel, and an operating handle extending into said channel and attached-to said shaft. Y

3. In a carpet sweeper comprising a housing fora dust compartment provided with a top and end Walls, an elongated aperture in said housing, a'shaft disposed Ywithin said compartment and mounted in bearings carried by said-end walls, a propelling handle attached to said shaft and projecting through said aperture and a tongue secured to the handle shaft frictionally engaging Ya spring carried by the housing to yieldingly retain said handle shaft at a selected position.

4." In a carpet sweeper having a dust compartment housing with a top and ends, a shaft within the housing and mounted in bearings at the ends of the housing, a slot in the top transverse to the shaft, a trim plate having a flange lying on the topvof the housing and surrounding'the slotand having a long well depending from the ange andrtting into the slot, the well having a notch across its bottom into which the shaft fits, the shaft extending yacross the bottom of the well, and a handle fastened to the part of the shaft in the well and extending out through the slot.

5. In a carpet sweeper having a dust compartment housing with a top and ends, a shaft within the housing and mounted in bearings atthe ends of the housing, a slot in the top transverse to the shaft, a trim plate having a iiange lying on the top of the housing and surrounding the slot and havingY a long well depending from the flange and fitting into the slot, the well having a notch across the central bottom portion into which the shaft fits, a saddle below and embracing the well portion of the trim plate and a portion of the shaft, the shaft extending across the bottom of the well, and a handle extending through the well and fastened to the part of the shaft embracedby the well.

6. In acarpet sweeper having a dust compartment housing with a top and ends, a shaft within the housing and mounted in bearings at the ends of the housing, a slot in the toptransverse to the shaft, a trim plate having a flange lying on the top of the housing and surrounding the slot and havingalong well depending from the flange and fitting into the slot, the well having a notch; across the central bottom portion into which the shaft fits, a saddle below and embracing thewell portion of the trim` plate and a portion of the shaft, a. pair of oppositely disposed balancing springs, each having one end of each spring attached to the shaft and the other end secured to the housing, the shaft extending across the bottom of the well, and a handle extending through the well `and fastened to the part of the Vshaft embraced by the well.
