FANNIE LITTLE TURNER OF CHARLOTTE, NORTH CAROLINA.
. MAGNETIC SWEEPER.
Application filed April 24, 1926. Serial No. 104,390.
Heretofore housewives have experienced great inconvenience in operating vaccum sweepers for cleaning floors, rugs, carpets, and other articles, due to the-fact that the vacuum sweeper will draw up metallic objects such as'ha-ir' pins, pins, tacks, and other similar articles, and said articles would penetrate the vacuum bag in the sweeper and cut holes-therein, and thus render the sweeper useless until repaired. p
My invention is designed to cure this inconvenience thus experienced by housewives, and to provide a device for passing over the floors of the different rooms before the vacuum swee er isused', thus picking up all of the metalllc objects which are capable of being attracted by a magnet, thus insuring that the vacuum sweeper will be protected against injury when the sweeping operation begins. that it may be adjusted at any desired height from the floor, and have also provided magnets of different lengths so t at both large and small metallic objects may be picked up and retained by the same.
My invention relates to a device for removlng metallic objects from floors and car-' pets, andmore especially to a wheeled device equipped with magnets, said magnets acting U to attract cert-ainmetallic objects scattered over floors and other surfaces.
-Another object of my invention is to provide a device for picking up tacks and other objects from the floors of a house, said device being capable of adjustment to regulate the height of the device from the floor.
Another objectof my invention is to mount a magnet or plurality of magnets on a wheeled frame in such a manner to render the magnets capable of attracting certain metallic objects as the wheeled frame is rolled over a floor or other surface.
Having thus stated some of the ob ects of my invention, other objects will appear as the description proceeds.
Abrief description of the figures in the drawings will now be given in wh1ch- Figure 1 is a front elevation of my device, with the handle broken away;
Figure 2 is a side elevation of my device with the handle broken away;
Figure 3 is a perspective view of the means for adjusting the height of the forward portions of the magnets;
I have so constructed my magnetic sweeper Figure 4 is a front elevation of a modification, showing a different type of magnet;
Figure 5 is a side elevation of a modification of my invention, as shown in Figure 4, with the rear portion thereof broken away.
Having briefly described the different figures in the drawings, a detailed description of the drawings will be given, in which like reference characters indlcate corresponding parts throughout the drawings.
The numeral 1 indicates the fioor or other surface on which my device is ada ted to be used. My magnetic sweeper has t e axle 2, upon the ends of which are rotatably mounted the wheels 3 and 4. The block member 7 is secured to the axle by means of cuffs5 and 6. This block member 7 has a forwardly inclined surface 8, while the rearface of the block member is approximately verticaL' This rear vertical surface has a plurality of grooves therein for the reception of the vertical portions of the magnets 9, 10 and 11.
To the rear vertical face of the block member 7 there is secured the block 12 which has the same length and breadth as the rear vertical portion of the block member 7. This block 12 has vertical grooves in its forward face portion, which grooves are of the same breadth as the grooves in the block member 7, and register therewith, and serve to receive the vertical portions of the magnets 9, 10 and 11. This block 12 is secured to the block member 7 by any suitable means, such as screws 13 and 14, shown in dotted lines in Figure 2. When this block 12 is thus secured it holds the magnets 9, 10 and 11 in a secure position.
To the rear face of the block 12 there is secured the means for adjusting the distance between the forward ends of .the magnets and the floor or other surface on which the magnetic sweeper is operated. This adjusting means comprises aU-shaped member 15 secured to the lower rear portion of the block 12 by any suitable means such as the screw 16. In the open end of this U-shaped member there is secured a pivot bolt 17 around which is rolled the lower end of the member 18, which has downwardly and rearwardly projecting portions 19 and 20, and between the lower ends of these members 19 and 20 there is rotatably secured the wheel 21, on the bolt 22. The member 18 projects upwardly from where the portions 19 and 20 emanate, and this upper portion has a hole therein for the recepltion of the end of the threaded bolt 23. T e forward end-- of this threaded bolt 23 has a head thereon which is loosel mounted between the cuff 24 and the blocli 12. This cuff 24 is secured to the'block 24 by any suitable means such as the screws 27 and 28, and has a hole therein thru which the bolt 23 passes. The rear end of this bolt 23 has a nut 25 thereon, and around the bolt 23, and located between the cuff 24 and the upper portion of the member 18, is a coiled spring 26, this. being a com-' pression spring, which normally forces the member 18 rearwardly against the nut 25 Secured to the axle 2 at points located between the ends of the block member 7 and the wheels 3 and 4,'are the ends 30 and 31 of the U-shaped member 32. Near the central portion of the base of'this U-shaped member 32 is secured the socket member 33 for the reception of the handle 34.
The magnet 10 is somewhat shorter than the other magnets, which allowslarger metallic objects to cling to it, while the smaller objects will be collected and held by the longer magnets 9 and 11. I
In Fi res 4 and 5 I have shown a slightly modi ed form of my invention in which I use a different type of magnet, commonly known as the horse shoe magnet. The type of magnets used in Figures 1 and 2 is in the shape of the hypotenuse and shorter leg of a right angle triangle.
In the modified form shown in Figures 4 and 5 I have a plurality of magnets 9, 10 and 11' mounted on the forwardly sloping surface of the block 7 and on top'of these magnets I have a board 12 secured to the block 7 by means of screws 13', 14' and 13.
The central magnet 10 is of shorter length than the others for the same reasons as previously described for the form shown in Figures 1 and 2.
The axle, wheels, handle, adjusting means,
and other parts of the modification are the same as in the form shown in Figures 1 and 2, except that the adjusting means already described are secured directly to the rear portion of the block 7, these parts being numbered 3' and 4' for the wheels, the axle 2, the cuffs 15' and 24', and the ends 30' and 31 of the U-shaped member 32'.
I desire it to be understood that although I have described my device throughout this specification as having a plurality of magnets, that I may have only one magnet mounted on the framework to perform the work erformed by the plurality shown and descri ed.
My devlce is operated by pushing the same over the floor, carpet or other desired surface. W hen it is desired to raise or lower the forward ends of the magnets so the space between the floor and the same will be lesser or greater, the nut 25 is turned on the bolt 23, and the center of gravity being to the rear of the axle, the adjustment will take place due to the action of the compression spring 26. When the desired adjustment is. obtained the device will be pushed over the floor or other surface and the metallic objects capable of being attracted by a magnet will be drawn from the floorand will attach themselves to the magnets and will remain there until the sweeping operation is completed, when they may beremove'd and the vacuum sweeper may be run over the surface without injur to the same.
Having thus descri ed one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
1.
