sUcTIoN CLEANER Filed Aug. 4, 1952 nventor UNITED Denver; Colo., assignor to Air-4 p'pliance Corporation, Toledo,

Patented Feb. 26, 1935 George vRos K Way Electric PATENT OFFICE Ohio, a corporation ofDelaware n Appiiationsnngfust I4., 1932, serial No.4 627.427

tools of the type wherein the'fsi defined between a pair rO15-*l1 y, structed with grooved workingilfavces, hegrooves tion -Arnouth isv forming air passages for producing `ets z )fair'v for cleaning contact with th e nap ofamug; The' present invention is characterized Uvbythe a` rangement of the slot-s or airp'assagesv sothat a number of centers of rotating, orfcyclfonic air; movement, will be set up within ftliefioory tool;` 1- the'fpi'clr up eflis` the cyclonic effect adding to ciency of the airA jets.

With these and other objects inv' vention consists in the combinatie struction and arrangement offthe variousiparts thereof, whereby. the objectscontemplatedare attained, as more fully set forth inthe accompanying specifications, pointed out in my claims,f

and illustrated in the accompanying drawing, in, which:

Fig. 1 is atransverse sectional view. through a suction cleaner oor tool embodying thezf'invention. r

Fig. 2 is an inverted plan view thereof, and Fig. 3 is a side elevationv of one of the agitators. In the channels 10 of the oor 'tool 1l, the agitators A and B are mounted so thattheir working faces C are positioned for contact with the floor, the suction mouth D being formed between the two agitators A and B,` which are termed lip agitators because they -form-the lips of the suction mouth. Each set of grooves is common to two adjacent groups. For instance,

the right set of a group E comprises the left set of the group, adjoining the said group E o n the right, and the left set of the said group E ccmprises the right set of the group F adjoining said group E on the left.

The working face of each agitator is serrated with a number of groups of grooves'E and F; the,

opposite the groups F ofthe agitator B.- In

order that this may be accomplished without the necessity of providing two dierent agitators,

each agitator terminates at one'end with a group E and at its other end with a group F, as shown, so that when arranged in the oor tool with one agitator reversed, end for end, relative to the other, as itfmust be in order that the agitators may face each other, the groups E and F will be disposed opposite .each other.`

The invention relates to suctidcleaner .liioor As a result of the opposite inclinationy of the alternatev groups E and F, the air currents com- Aing through'an agitator will be divided into alternate groups of converging and diverging air vjets,.as indicated by the arrows 15. Opposite the enters of the converging air jets there will be :produced regions of increased air pressure 16 moving toward the opposite side of the mouth asindicated by the arrows 13, while opposite "thecenters of the diverging groups there will .A toward which the air from the high pressure areas 16 will flow. The result will be a number of centers G and H of rotating air movement. This will betrue whether one or two agitators lare used, but the elect will be much more pronouncedv with two agitators, for the reason that the low pressure region 17a adjacent the agitator B will be directly opposite the high pressure region 16 adjacent the agitator A, while the high pressure region adjacent the agitator B will be directly opposite the low pressure'region 17 of the agitator A, and the direction of the various air jets is such as to carry the air from the high pressure regions 16, 16a to the low pressure regions 17; 17a respectively, and all air jets are tangent to the rotating air swirls G, H, and travelling in the respective directions of rotation. In order that the air jets may assume the well defined directions of travel inside the mouth, necessary tothe creation of the air swirls G and H, it is necessary that they maintain their direction of initial injection to some extent after entering the mouth D. To this end, it is essential that there be several parallel grooves in each set comprising one half of a group E or F, as the case may be, since if only one groove were em ployed in each set, the centers of the groups would be too close together to secure this result.

Furthermore, the jets entering the mouth would then be all directed at right angles to the axis of the mouth, whereas in the present invention, the jets lentering through the innermost grooves 14 of a converging group F will be thus directed at right angles to the axis, but the jets entering4` from -the intermediate grooves 18 and outer grooves .19 (the inner grooves of the groups E) will enter at a very distinct acute angle to the axis of the mouth. Thus in the former case, the

peripheries of the swirls G, H, would be impinged upon only at diametrically opposite points, whereas in the present invention they are impinged upon from both right angled and acute angled (relativeto Athe mouth axis) directions.- To further increase the number of directions of lld contact, the grooves 19 are disposed at angles of about 45 whereas the grooves 18 are disposed at angles of about 60, thus aiding in the maintenance of tangency of impingement.

The swirls G and H serve to increase the suc-` tion at the centers of swirling movement, whereby to increase the pick up efficiency of the tool.

The grooves 14 may be termed neutral, for the reason that the air jets issuing therefrom neutralize the initial acute angular directions of each other so as to produce a single jet at right angles to the axis of the mouth.

Triangular lugs 20 are formed between the grooves 19.

What I claim as my invention is,

1. A lip agitator for attachment to a suction cleaner floor tool to dene one side of the suction mouth thereof, said agitator being provided with a working face formed with a plurality of groups of grooves each extending from the outer to the inner side of the agitator and inclined relative to the longitudinal axis thereof, each group comprising two sets of several grooves each which sets are each common to two adjacent groups, the grooves of one set being inclined opposite to the direction of inclination of the other set of a given group, and the sets of alternate groups converging toward the floor tool mouth while the sets of the intervening groups diverge toward said mouth, whereby air jets issuing into the mouth through said grooves will produce Within the floor tool a series of spaced centers of rotating air movement.

2. A lip agitator for attachment to a suction cleaner floor tool to dene one side of the suction mouth thereof, said agitator being provided4 withV a working face formed with a plurality of groups of grooves each extending from the outer to the innerside of the agitator and inclined relative to the longitudinal axis thereof, each group comprising two sets of several grooves each which sets are each common to two adjacent groups, the grooves of one set being inclined opposite to the direction of inclination of the other set of a given group, and the sets of alternate groups converging toward the oor tool mouth while the sets of the intervening groups diverge toward said mouth, triangular lugs being formed between the sets of the divergent groups, and neutral air passages being formed between the sets of the convergent groups whereby air jets issuing -into the mouth through said grooves will produce within the oor tool a series of spaced centers of rotating air movement.

3. In a suction cleaner, a iioor tool provided with a pair of spaced lip agitators dening the suction mouth thereof, each agitator having a working face provided with a plurality of groups of' grooves, each group comprising two sets of several grooves each which sets are each common to two adjacent groups, extending from the outer to the inner side of the agitator and inclined relative to the longitudinal axis of the agitator, the grooves of one set being inclined in a direction opposite to the direction of inclination of the other set of a given group, and the sets of alernate groups converging toward the oor tool mouth while the sets of the intervening groups diverge toward said mouth, the converging groups of one agitator being disposed opposite the diverging groups of the opposite agitator, whereby air jets issuing into the mouth through said grooves will produce within the floor tool a series of spaced centers of rotating air movement.
