PNEUMATIC CLEANING TOOL Filed April 22, 1926 9 g H 5 M ATTORNEY:

Patented Nov, 18, 1930 UNITED STATES PATENT OFFICE PNEUMATIC CLEANING 'roor.

Application filed. April 22,

This invention relates to pneumatic cleaning tools, and particularly to a combined vacuum cleaner including a curry comb and brush, which implements or cleaning tools may be applied to a head alternately, the said head being connected to a suction pipe, whereby dust and hair dislodged from animals during the cleaning operation will be drawn from the implements and conveyed to a location where they will be discharged from the apparatus.

It is an object of this invention to produce a novel head adapted to be associated with a curry comb and with a brush, the same having novel means for securing the implements to the head, whereby they may be changed expeditiously as the work progresses.

A further object of this invention is to produce a vacuum cleaner of the character indicated having comparatively few and inexpensive parts, although eflicient and satisfactory in use.

With the foregoing and other-objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to he hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying raw- 30 ings forming part of this application, wherein likecharacters denote corresponding parts in the several views, and in which- Figure 1 illustrates a plan view of the device embodying the invention;

Figure 2 illustrates a sectional view on the 'line 2-2 of Fig. 1;

Figure 3 illustrates a view in side elevation of a brush to be substituted for the curry comb; and

Figure 4 illustrates a plan view of a fragment of the brush frame.

In these drawings, 5 denotes a conventional type of motor and 6 a suction casing, it being understood that the casing shall contain blades which rotate and which are effective to draw air into thecenter of the casing and discharge it through a spout 7 at the periphery of the said chamber. The motor and fan or suction apparatus maybe of any conventional type and the inventor does not wish 1926. Serial No. 103,898.

to be limited with respect to the details of their construction so long as the blades of the fan are set to produce the desired result.

A vacuum or intake pipe 8 is connected to the casing 6 and a flexible tube 9 extends therefrom a suitable length, for the purpose of permitting the implements to be manipulated through the length of animals to be groomed. Figure 1 shows the flexible tube as broken away so that the length thereof is indeterminate. A head 10 is connected to the tube and communicates therewith, the said head having an opening on one side, through which air will be drawn. The head has a rim 11 with seats 12 and 13, into which apertured lugs 14 of a curry comb frame 15 may be lodged. The rim has apertures 16 and 17 at each end registering with the apertures of the lugs, for the reception of pins or other anchoring elements 18 by which the curry comb is retained in place.

It will follow from an inspection of the drawing and from the foregoing description that after the curry comb frame has been applied to the head and the retaining elements 18' are in place, the'curry comb will be retained and the head may be manipulated, as is usual in the grooming process. The frame of the curry comb is provided with a plurality of plates 19 whose edges are serrated, as shown at 20, and these plates are anchored in the frame in appropriate way, as shown in Fig. 2. I

When the curry comb has been used to an appropriate extent, a brush 21 may be substituted for the curry comb, it being shown that the back or body of the brush has apertured lugs 22 which areintended to fit in the seats of the rim of the head and secured therein by the same fastenings or like fastenings as are 90 employed in holding the curry comb in the head. The brush back has openings in it which permit air 'to be drawn through the bristles of the-brush into the Vacuum tube in the same way as that described in connection with the use of the curry comb.

The spout 7 is preferably connected to a rece1v1ng bag 23 of appropriate material such, for instance, as is used in vacuum cleaners fo' use on carpets and the like.

I claim:

In a vacuum cleaner, an attachment consisting of a head adapted to be connected to a vacuum creating instrumentality, the said head having a rim with seats formed therein in spaced relation to each other, a frame of the general contour of the inner surface of the rim having lugs fitting in the seats of the rim, means extending through portions of the rim and said lugs for securing the lugs to the rim, elements extending parallel to each other and spaced apart on and carried by the frame, and dust dislodging elements on said elements.
