3 Claims.

The invention relates to cleaners of the suction type and has for its main object to provide a device means of which feathers, cotton, s and ot materials employed for filling or I long mattresses, pillows, cushions, quilts and ot er articles, may be readily and speedily removed the surface of such articles after they have filled or stuffed. Another object is to provide use us for the expedient collection and rethe substances removed. A further obto so construct the brushes employed in the macl h that any substance adhering to them may y removed. A still further object is to e a macline of and inexpensive conon, which will occupy but small floor space, es no skill to operate, and which can very low cost.

stood from the followi g descripand from the accompanying drawing of a rred embodiment in which, however, modiay be made without departing from e appended ol In the drawing r nt elevation of the preferred emie cleaner with a certain part shown away to expose the interior,

' a side elevation,

cross-sectional side elevation taken the scope now to all the views, simultaneously, ine consists of a pair of side frames ich are spaced apart and connected by l3, l4 and 15. The general contour of 3 frames is plainly shown in Figs. 2 and 3, so also the locations of the tubes. The front sides of upper ends of the frames are curved and to these parts a curved plate is secured. It is provided with a rectangular opening 17, as shown, across which a plurality of rods 18 are placed.

The lower cross member 19, of the side frame 10, is provided with a vertical socket in which a bar 20 is clamped by a set screw 21. A platform 22 is provided at the upper end of the bar and on this an electric motor 23 is securely bolted. The motor drives a suction fan 24 which is preferably suspended from the

tubes

12 and 13 by means of bosses 26, but may, of course, be constructed and supported in any other suitable manner. The air-intake opening 27 of the fan is located inside one end of a receptacle 28, while the airoutlet 29 is turned towards the rear of the machine. A chute 30 extends upwardly from the other objects and advantages will be receptacle 28 and its upper end is connected with the plate 16 so that the fan will draw air through the openin 17. The chute is of the same width as the openi A pulley 3]. is mounted on the motor shaft which, by means of a belt 32 and another pulley 38, drives a shaft 34 on which. rotary brush 35 is removably mounted. We prefer to support the shaft 34 in a pair of bearings 36 which are placed on opposite sides of the chute and to provide means on these bearings so that they may be moved forward to compensate for any wear on the brush. The brush islocated within the chute and adjacent to the opening 1? so that its hairs project slightly through the opening. its location is plainly shown. in Fig. 3. A door 37 is provided in the receptacle for cleaning purposes.

The pulley 33 is preferably mounted to rotate on the shaft 3% if the brush should accidentally catch in the material operated on. A friction clutch 38, of any standard spring-actuated type is pinned to the shaft and exerts sufficient friction against the pulley to drive the shaft under ordinary conditions. A stationary shaft 39 is mounted below the opening 17 and on this shaft a plurality of flexible beater-s .0 are secured. Another shaft 41 is rotatingly mounted above the opening 17.

It rotates in bearings 42 which are located on opposite sides of the chute and is provided with a plurality of catches 4E3 hich engage with the ends of the heaters. This shaft is driven from the shaft 34 by means of any suitable train of gears such, for example, as shown at 44: and it rotates at a much lover speed than the brush shaft.

The machine operates in the following manner:

It is well known that a pillow, mattress orother article after being filled or stuffed will have particles of the filling material adhering to its outer side which must be removed. When the motor 23 is started the fan creates a suction through the opening 17 and if new a pillow, or other article, covered with particles of the filling material is placed upon the plate or table 16, the part covering the opening will be freed of these particles by the suction through this opening. By moving the article in front of the opening it is evident that it may be entirely cleaned.

As certain filling materials adhere more tenaciously than others, the brush 35 is provided. The brush loosens the particles which are then readily carried off by the suction. The rods 18 prevent the article from being drawn too far into the opening. The particles removed are drawn down through the chute and into the receptacle 10 from whence they are drawn through the fan. Bags may be attached to the air outlet 29 for collecting the particles removed.

To increase the speed with which an article may be cleaned, the heaters l are provided. These heaters, which are normally straight, are engaged by the catches d3 so that their ends are drawn bacl: and released, as plainly shown in Fig. 3 where the dotted position shows a beater after it is released. lhe heaters are interposed between the tufts of hair in the brush so as not to interfere with these. As the heaters apply rapid blows to the article operated on, the particles adhering thereto are loosened and so readily removed.

As some of the filling materials used, particularly if consisting of long fibres, have a tendency to twine around the brush and work down towards the brush body to stick firmly there, a plurality of grooves are milled in the brush body, asshown in Fig. i. To remove this adhering material a sharp knife is run lengthwise of t -e grooves to cut it, after which it is easily removed. While a brush having four straight rows of hairs has been illustrated, it will be under stood that brushes of other constructions are employed according to the material operated on. The brushes are therefore made interchangeable.

The foregoing will show that the device is very simple in its construction and that no special skill is required to operate it. While the machine has been described for use on filled or stuffed material or articles, it is evident that it may he used on many other articles. For this reason we do not wish to limit the invention to any particular use only.

Having described our invention and its operation, what we claim and wish to protect by Letter 5 Patent is:

1. In a suction cleaner of the class described; a frame structure; a plate located the upper part of the frame structure for supporting the articles to be cleaned; an aperture formed said plate; a duct leading from said aperture; a rotary 3 brush located within said duct, adjacent to said aperture, for brushing the articles passed over the a erture; the bristles of said brush arranged in spaced, cylindrical rows; a plurality of 6,5331% heaters also located within said duct, transversely with and in close proximity to said aperture, for beating the articles passed over the aperture; said heaters interposed between the 1' vs of bristles of the brush; one end of each of said heaters secured to a stationary shaft located substantially behind one edge of the aperture; a rotating shaft located behind the opposite edge of the aperture; a plurality of catches secured on said rotating shaft; the free ends of aid heaters engaged and flexed by said catches; an exhaust fan connected with the duct; and means for actuating said rotary brush, said rotary shaft, and said fan.
