Patented Dec. 29, 1931 [UN TED STATES PATENT OFFICE HENRY HARLOW WRIGHT, .OF WORCESTER, MASSACHUSETTS, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO THE SWEEIER-VAC COMPANY, or woncnsrm, MASSACHUSETTS, A

, CORPORATION OF MASSACHUSETTS CLEANER APPARATUS Application filed January 80, 1926, Serial N'o. 84,971. Renewed June 25, 1931.

V This invention .relates to suction or vacuum cleaner apparatus, and more particularly to a novel 7 improved attachment for the mouth or inlet part of nozzles for said cleaners.

One of the objects of the invention is to provide means whereby a support or carrier for a brush or the like may in a convenient '1 and novel manner, be readily applied to, and removed from the vacuum cleaner nozzle with associated means whereby the said support or carrier may be locked in place while in service.

More particularly the invention includes a carrier frame having surface-engaging parts such as bristles, the frame having side walls adapted to overlie the wall of the nozzle adjacent the mouth thereof, and means being provided to secure said frame in place against accidental displacement when placed in proper register with the walls of the nozzle.

Other improvements and novel details in the construction and arrangement of parts will be appreciated from the description to follow, which for a clear understanding of the invention is to be considered in connection with the accompanying drawings, form ing a part hereof, and wherein is illustrated a satisfactory and preferred embodiment of the invention.

In the drawings:

Figure 1 is a bottom plan of a nozzle for vacuum cleaners having my improved attachment applied thereto;

Figure 2is an end or side wall elevation of a nozzle with the mouth or inlet end thereof in section and with my improved attachment applied thereto and shown partly in section,

I this view being taken substantially on the line 2-2 of Fig. 1;

Figure 3 is a detail sectional view of the nozzle and the improved attachment, the Section being taken on substantially the line 33 of Fig. 1;

Figure 4 is a vertical elevation, cut away, of the nozzle with an end portion of the improvements applied to said nozzle; and

Figure 5 is a perspective of my attachment removed from the nozzle.

With more particular reference to the drawings, wherein like reference numerals refer to corresponding parts throughout the views, 1 is a nozzle for vacuum cleaners having an inlet or mouth section 2, the lower terminal 3 of which is adapted to normally engage with the surface to be cleaned when it is not deemed desirable to utilize brushing characteristics in the cleaning operation. The front wall of the nozzle is. preferably provided with a recess 4 connecting with a beaded part 5 and the rear wall of the nozzle is preferably provided with an enlarged recess 6 connecting with a beaded part 7. A suitable supporting frame preferably takes the form of spaced bars of rods 8 and 8a connected. by means .of cross. brace members "9 preferably arranged adjacent opposite ends of the rods 8-.8a whereby to leave the major portion of the mouth of the nozzle, when the attachment is applied, free and unobstructed. The cross brace members 9 preferably projected over the under surface of the rods 88a are curved around the side edges thereof and adapted to be securedatthese points by means of screws or the like 10. This construction and arrangement of brace members 9 makes it possible for the rods 8-8a to assume a position above the lower edges of the front and rear walls of the nozzle. The rods 88a are adapted to have connected thereto tufts of bristles or the like 11, whereby to provide elongated brushes adjacent the front and rear walls of the nozzle when the attachment is applied, the. bristles of the brushes projecting below the lower edge of the nozzle whereby to engage the surface to be cleaned.

While the connecting brace. members 9 may have a slight elasticity, it is preferable that the same be substantially rigid whereby to afi'ord'a more effective support.

The rods 88a are preferably spaced from one another a distance sufiicient to enable them when being applied to the nozzle to ieadily pass by the beaded portions 5' and 7 when the front rod 8 will assume a position in the recess 4 connecting with the beaded portion 5 at the front of the nozzle. In order to lock the attachment in place on the nozzle with said rod 8 in snug contact with the chamber provided by the recess and beaded portion at the front of the nozzle, there is provided a retaining means on the rod 8a, substantially as follows.

Sleeved upon the rod 8a is a collar which collar has connected thereto a finger operating lever 12. The collar 11a has an enlarged or raised part 11a forming a cam or eccentric 12a, which in the rotatable movement of the collar will engage in the enlarged recess 6 at the rear of the nozzle and thereby bring the brush support into locking engagement with the nozzle.

When desired to remove the brush attachment, it is only necessary to engage the finger lever 12 and exert downward and rear pressure thereon when the locking part 12a of the collar will be moved into a position whereby to free the rods 8-805 from the nozzle.

Preferably two locking levers are provided, as illustrated in the drawings, one adjacent each of the cross braces 9.

It is obvious, of course, that if desired the attachment just described may be utilized for service in connection with surface-engaging means other than brushes.

7 What I claim is: a

1. An attachment for a vacuum cleaner nozzle, having a recess in the front wall thereof adjacent its mouth, said attachment comprising opposed rods with connecting braces, one of said rods being adapted to engage in the recess of the nozzle, and the other of said rods having a pivoted locking cam to engage the rear wall of said nozzle alnd rigidly secure the attachment to the nozz e. j

2. An attachment for a vacuum cleaner nozzle having front and rear recesses adjacent the lower edge, said attachment-comprising elongated spaced rods having a curved surface adapted to seat in said recesses, relatively thin fiat'braces, one adjacent each end of the attachment and curved about the side edges of said rods, whereby to leave the inner surface of the rods free from obstruction to permit the rods to have longitudinal slidable movement in said recesses, brushes on the rods, and pivotal locking means spaced from said. braces carried by one of said rods, said locking means being retained on the rod by being sleeved thereon, said locking means having aneccentric projection to engage the adjacent wall of the nozzle to lock the attachment in place, and a handle part connecting with said locking means, adapted in the locking position to assume a position substantially flat against theadjacent surface of the nozzle to offer no substantial obstruction laterally of the nozzle.

3. An attachment for a vacuum cleaner nozzle having front and rear recesses adjacent the lower edge, said attachment comprislng a pair of elongated round rods, relatively thin fiat braces, one adjacent each end of the attachment and projecting around the side edges of said rods and secured thereto, whereby to leave the inner surfaces of the rods free from obstruction to permit the same to freely move with respect to said recesses, cleansing means on the rods, to engage the surface to be cleansed, and pivotal locking means carried by one of said rods, said locking means being sleeved upon the rod, for pivotal movement, and said locking means having an eccentric projection to engage the adjacent wall of the nozzle in one of the positions of said locking means to retain the attachment in place, and a handle part for said locking means.

In testimony whereof I hereunto aflix my signature.

HENRY HARLOW WRIGHT.
