cem s. sldanels. Kansas city, Mo. Application March 12, 19471,"Serlal No. 382,907

This invention relates to cleaning apparatus and particularly suction sweepers for floors and the like, and the primary object is to provide means for collecting particles that would`normally enter the sweeper mechanism and have a detrimental effect upon the same or the receptacle employed to collect matter that customarily passes through the intake mouth ofthe apparatus.

of the mechanism are protected against the destructive effects of such foreign articles as tacks,

pins or the like.

The specific manner of constructing a vacuum sweeper and the magnetic attachment therefor, constitute important objects of the invention and such will appear during the course of the following specication, referring to the accompanying drawingwherein:

Fig. 1 is a diagrammatic, fragmentary side elevational view of a vacuum sweeper embodying the present invention.

Fig. 2 is a front fragmentary elevational view thereof. n

Fig. 3 is an enlarged fragmentary sectional view taken on line III-'III of Fig. 2, looking in the direction of the arrows.

Fig. 4 is a fragmentary-sectional view taken on line IV-,IV of Fig. 2.

Fig. 5 is an inverted fragmentary planv view of the sweeper mouth, illustrating a modifiedform of the invention; and

, Fig. 6 is a fragmentary sectional view through a portion of the sweeper illustrated in Fig. 5.

Conventional vacuum sweepers provided with a casing usually have motors Ill and an intake mouth I2, andYY are moved over the surface being treated upon wheels I4. The matter drawn from the surface being cleaned passes through mouth I 2 to a receptacle or the like, not here shown, and

In the form of the invention shown in Figs. 1 to 4 inclusive, a bracket I6 mounted on case 8 near mouth I 2, carries an armature or magnetic member I8 of a length equal to the width of mouth I2.

An upwardly extending portion 20 of member I8 constitutes the core of coil 22 and has a copper ring 24 circumscrbing the same to eliminate chattering that would otherwise occur when the vacuum sweeper is being operated through the use of alternating current supplied through electrical conductors 26 and 28.` oil 22 is in-the circuit with motor I0 and whe switch 30 forming a part of the vacuum sweepei' 'is closed to supply current to motor I0, electrical energy is supplied to coil 22 for the purpose of magnetizing amature or member I8. Housing 32 protects coil 22 and portion 20 with ring 24 thereon, and a` bumper 34should be carried by the forward wall of housing 32.

Bracket I6 has a track 36 formed thereon which in this instance, is a groove that is dove- Y plurality of permanent magnets are used and held in bracket 50 mounted on case 8 of the conv ventional vacuum sweeper, adjacent to the mouth the means for collecting metallicarticles islocated just ahead of mouth I2 where-the same the mouth.

I2 thereof. These permanent magnets 52 are in the form of bars arranged in at least two parallel rows with the vends thereof spaced apart and the ends of the bars in one row in a position close to the medial transverse portion of the bars in the adjoining row. Thus polarization,l I

which is normally present and which presents magnetism of different intensity when permanent bar magnets are employed, is not a factor effecting the efficiency of the vacuum sweeper when these said magnets are employed. The series of magnets 52 combine to present a continuous magnetic part extending the full length of intake mouth I2 of the sweeper and therefore, as the apparatus is moved forwardly along the floor covering being treated, any foreign objects that are attractable by a magnetic vforce will be prevented from entering mouth I2.

It is desirable to provide means for cleaning permanent magnets 52 and as has been made clear in the foregoing description of the form of invention shown in Figs. 1 to 4 inclusive, a wiper 56 is siidably mounted upon a track it for movement longitudinally along all of the magnets. Arm 58 is in frictional engagement with the lowermost sides oi' all permanent magnets 52 carried by bracket 50 and when the operator grasps handle 60, it is easy to move wiper 54 from end-to-end of the series of magnets and thereby wipe therefrom any particles adheringy thereto.

It is understood that vacuum sweepers having Y physical characteristics different from those shown in the drawing may be made without departing from the spirit of the invention or scope u of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a vacuum sweeper having a mouth; a bracket along one edge of the mouth; and a series of permanent magnets carried by the bracket, said magnets being in the form of bars arranged in at least two parallel rows with the ends of the bars of one row disposed near the means medial transverse portions ofthe bars in the adjoining row.

2. In a vacuum sweeper having a mouth; a bracket along one edgeof the mouth; and a series o! permanent magnets carried by the bracket, said magnets being in the form of bars ar.

the ends of the bars of one row disposed near the medial transverse portions of the bars of. the adjoining row, said magnets being disposed on the horizontal leg of the L-shaped bracket, said bracket having a Wiper mounted on the vertical leg of the bracket for movement across the faces oi' all the bars.
