CARPET SWEEPER Filed Jan. 22, 19:57 2 Sheets-Sheet 1 Patented Nov. 28, 1939 UNITED, STATES PAT NT o-rrlcs 2,1:s1,455 I CARPET SWEEPER- Henry W.- Gussack, Richmond Hill, N. Y. I Application January 22, 1937, Serial No. 121,895 1 .12 Claims. (01. 15-48 This invention relates to a new and improved carpet sweeper in which means are provided for cleaning the rotary brush or brushes.

It is an object of the invention to provide means whereby .the comb or teeth acting as a cleaner for the rotary brush or brushes may themselves be effectively cleaned upon the opening or evacuation of the dust pan. e

A further object of the invention is to provide means which will simultaneously actuate the comb or combs and open the dust pan.

A further object of the invention is to provide a new and improved unitary construction for the casing enclosing the carpet eleaningmechanism.

A still further feature of the invention is to make the outer casing from a single sheet of metal.

With these and other objects which will become apparent as the description proceeds, the invention is set forth in detail below, claimed in the claims and shown in the drawings, in which:

Fig. 1. is a plan view of the improved carpet sweeper. 1 r I r Fig. 2 is a cross sectional view talzen on. the section line 2-2 of Fig.1.

Fig. 3 is a slightly enlarged cross sectional view taken on the section line 3-3 of Fig. 2.

Fig.4 is an enlarged view of a detail at one corner of the carpet sweeper looking upwardly, n

Fig, 5 is a partial plan View illustrating a modification.

Referring to the drawings in which similar reference characters indicate like parts, the cas ing of the carpet sweeper is indicated atl. The casing comprises a unitary sheet of metal stamped into the form indicated. Secured to the outside of the casing l in anydesired manner is the ordinary buffer elements 2. v Wheels 3 of the usual type are mounted on the shafts 4 and the shafts 4 in turn extend through the slots 5 in the transverse walls- 8.

The dust pan elements 6 are in turn pivotally mounted by the pivot I to the'transverse members 8 secured within the casing l. v

The usual rotary roller 9 fits between the wheels 3 and the handle member It? has the side arms I l with in-turned portions fitting within recesses provided at the: ends of the rotary brush. The handle member H3 therefore provides the trunnions for the brush member ,9 which is the usual construction.

Spring members l2 are provided with one end secured to the underside surface of the casing l and the other end secured to the shafts 4 in order tornaintain the wheels- 3-inth elposition shown in Fig. 2. The dust pans 8 areprovided with inturned flanges l3 fitting within the recess it provided. inia member l5 Whichis secured by spot welding or otherwiseto. the interior side :5 Walls of the casing I.

The means for fitting the dust pan so as to empty the same comprises the followingi A U- shaped loop member 16 is pivotally secured to the interior edge ,I] of each dust pan. Upon! =10 movement of the loop memberit the dust pan will pivot about the pivot l and thereby permit the .p an to beemptied. A double armed lever member l8 pivoted at Hand having an actuatlng member 20" a pivotal connection with the 15 looped member Hiat 2| so that upon actuation of the member 20 downwardly; as shown in Fig. 2,

the looped member [6 will be moved upwardly and thereby pivot both dust pans. Upon release from the action of they lever I8 the member it 20 will exert a spring like action upon the dust pans to hold them in closed position.

A series of teeth 22=are provided upontheba-r member 23 and extend-downwardly so asto contact the bristles on the brush member l3 and clean 25 the same) The teeth22 and the bar member 23 constitutes acornb member'fjTwo comb members are shown in the modification being described, but it isobvious that only one may be provided If desired or more than'two. 30 The comb members shown more particularly in Fig. 3 of the drawings are supported with the bar member23 on the outside of the casing l and with the'teeth 22 preferably somewhat pointed extending downwardly into the interior of the 35 casing. The teeth are maintained in aligned position so as to prevent-any pivoting by the member 24 which is seoured'to the under surface of the casing l in any desired manner with a felt mem-' ber 25 intervening. The felt member 25 is de- 40 signed to closely fit against the teeth 22 and upon movement of the teeth'22 with relation to the felt member'25 effectively remove from the teeth 22 any adhering dust, dirt or fibers. a

The member 24 is provided with downwardly 45 grooved portions 26 which portions have provided therein apertures 21 for the passage of teeth 22. The grooved portions are spaced from the lower surface of the casing I so that the shorter movement of the teeth 22 is required for cleaning the 50 interior surface of the teeth 22. As is obvious if the grooved portions 26. were not provided then the teeth 22 would have to be practically entirely raised out of the casing member l in order to clean the'lower portions thereof, while with the 55 grooved portions 26 spaced some distance from the under surface of the casing I, such an ex treine movement is not necessary. The felt member 25 may be of any desired character and. is preferably a loosely woven material which will closely adhere to the sides and surface of the teeth 22.

The means for actuating the teeth 22 and cleaning them comprises the following: Secured at the interior edges of each of the dust pans 6 are the links 28. The links 28 are pivotally secured to such edges in any desired manner and the upper ends 29 of the links are connectedto a lug 30 integral preferably with the bar member 23 and projecting downwardly in the plane of the teeth 22. As will be noted upon downward actuation of the member 20, the dust pans will be pivoted in the manner described above,

and at the same time the links 28 will be raised upwardly and thereby raise the bars 23 carrying with them the teeth 22 which, upon movement will be cleaned by both the apertures 21 inthe metal member 24 and also the adhering felt member 25. In this manner upon actuation of the dust pan, the teeth are cleaned at the same time. Generally the teeth 22 are arranged in staggered relation as shown particularly in Fig. 4 cf the drawings.

A modification of the invention is shown in Fig. 5 wherein instead of having twoseparate bars 23 as shown in the modification described above, a single bar member 3| ,is provided, from which one or two sets of teeth may project. The remainder of the construction in this modification is similar to that described above.

As will be noted from. the above, the working parts are all assembled as a separate unit and may be installed as a single unit into the one piece casing. The separate unit comprises the elements l5 with the transverse member 8 and after the casing has been properly stamped out such unit with the cleaning equipment may be easily secured to the casing.

As will be noted when the teeth of the combs are moved for cleaning purposes, any part which adheres thereto will be moved off and into the :lust pans.

Whenever there are two or-more combs they may be suspended through perforations in the body independently with small narrow heads on the outside of the body, or they may issue from one master plate which lies on top of the out side surface of the sweeper in such .a way as to permit the teeth to extend through the perforations provided in the casing member itself towards the center sufficiently' to clean the brush bristles.
