SUCTION SWER.

Application filed Gotober 20, 1919 serial No. 831,908.

ratus the height of which shall be as low i To all whom it may concern:

Be it known that I, HOWARD EARL Hoovan, a citizen of the United States residin at Chica o, in the county of (look and tate of Illinois, have invented a certain new and useful Improvement in Suction Sweepers, of which the following is a specification.

My invention relates to a combined installed plant and motor driven brush apparatus for suction sweeper. Generally speaking the object of this invention is to provi e means whereby a motor driven and particularly a beating brush or a brush-' ing and beating apparatus motor driven of any kind can be used in and with a nozzle while the suction apparatus associated therewith is placed at a distance, as for example, in a stationary lant in the basement of the buildin In't e referred form of my invention, use a device which has both a beating and a brushing efi'ect and I drive it at a high rate of speed by means of a motor mounted on and associated with the brush nozzle. A flexible conduit leads from the nozzle to the ipe or conduit which connects with the installed or stationary suction lant so that the nozzle can moved reely about the room where the sweeping or cleaning is to be done. This flexible conduit may connect directly with the nozzle body or as shown in a modified form herewith to a handle or handle portion which is hollow and connected with the nozzle. The first is the preferred form of this application.

In the preferred form of my device, the nozzle is rovided with a relatively wide open mouth and this is preferably supported above the floor so that the carpet or floor covering will rise thereto and the mouth will be big enough to furnish a proper field of operation for the heater and the brush or the beating brush. In, the preferred form the connection between the handle or handle device is made as shown in front of the center of gravity of the machine and my object in this is to keep the dirt from spilling out of the casing w en the machine is lifted from the fioor. Another object of my invention is to produce a sweeping appabe rollers A b possible to permit its insertion under articles of furniture and where the handle or combined handle and conduit will be capable of being swung down in the horizontal osiltion below the highest portion of the My invention is illustrated in the accompanying drawings .wherein- Fig. 1 is a plan view with parts broken awa Fig. 2 is a side elevation;

Fig. 3 is a lan view with parts broken awe. of an a ternative form;

Fig. 4 is an elevation of that form;

Fig. 5 is a detailed section along the line 55 of Fig. 3.

Like parts are indicated by like characters in all the figures.

A is a movable suction head havin along its front side an enlarged brush c amber A having a downwardly open wide suction mouth A arranged to be held above the floor by the rollers A ad'acent the suction mouth and the adjustable rollers A removed from the suction mouth. The arrangement is such that adjustment of the rotating the entire suction head about t e rollers A will change the height of the suction mouth or nozzle above the floor. A A are brush guard fingers extendin across the open mouth to make it impossib e for any rug or floor covering to be drawn up too far into the open mouth. The brush chamber A communicates toward the rear with an enlarged bifurcated suction chamber, the two arms of which communicate with the brush chamber adjacent its two ends and are at the other end, joined and communicate with a hose pipe connection sleeve A. The arrangement is such that the air will be drawn oil through a pipe A communicating with the sleeve A", and because the cross section of the air passage as shown decreases from the nozzle or suction mouth rearwardly toward the sleeve, the suction and velocity at the, suction mouth will be less than that in the pi e.

is a combined beating and sweepin brush, the two separate functions of wine either end in the housing. B B are thread guards surrounding the ends of the bear-.

ings to protect the bearings from fouling. B is a pulley on the brush whereby the belt B which is driven in turn by a pulley B may rotate the brush. B is a removable hand hole cover in the side of the belt housing 13 whereby access may be had to the pulley B for the purpose of adjusting the belt B B is a belt housing and motor support mounted upon and integral with the suction head It forms throughout a part of its len h a channel separate from the suction hea and communicating with rt adjacent the brush chamber A ut into which the dust laden air is not drawn.

0 is a motor enclosed within a casing as indicated. It is located above the passageway through the head and is mounted upon the belt housing B.

In Fi ure 3 I have shown a modified form in which the belt housing B is of greater width than that shown in the preferred form' of Fig. 1 and in which the motor housing is partially enclosed within such housing.

A combined conduit and handle F is substituted for the handle D and conduit A of Fig. 1. -The handle F is a hollow handle adapted to be connected at its upper end to a flexible conduit which is in turn connected to the suction system. To provide for motion of the conduit handle, a hose pipe connecting sleeve H is rotatably connected to the two ends of the bifurcated suction chamber. The supporting wheels A are mounted gireictly on a rearward portion of the suction The handle stop D is mounted on the motor housing and upon the conduit handle.

G is the rotatable union of the hose pipe connecting sleeve H and the arms of the suction head and is made up of the lips G on the end of the opposite arms of sleeve H the holding band G which grips them and the screw G which clamps the holding band in position.

J J are a series of holes as here shown diagrammatic but ada ted to be arranged in any manner about t e motor bearing in the wall of the belt housing. They may or may not be used. Under certain conditions of operation or with certain desi us of machines they would be desirable. ith others they might be unnecessary. They would admit air about the motor bearing and develop 1 a current of air toward the brush throu the brush chamber and thence through t e rearwardly extending partthus keeping the belt housing chamber free from dust and the bearings protected from dust.

essrs Without such holes the bearing is in a pocket in which there is little if any tendency for dust laden air or particles of dust or material to penetrate.

K is the motor socket or base casting. It may be part of the general housing casting or it may be secured in position on the general housing casting as for example, the screws K K. It carries at its outer end, a cap frame or head casting K in which the shaft of the motor is supported. One hearing of the motor shaft is carried by the cap frame K and the other by the base casting or socket K. K is a cap which surrounds the end of the motor and the cap frame.

The use and operation of my invention are as follows When the machine is put into operation the dust laden air is drawn through the nozzle brush chamber rearwardly projecting part and out through the conduit in the usual way. The motor is let down upon the downwardly bent portion of the rearwardly extending part so that it occupies the least ossible space so that the apparatus should e relatively low. The bifurcated device in the rearwardly extending portion whenused can be designed so as to insure a practically uniform movement of air along the length of the brush. If the belt housing is associated with the motor pocket, the motor can be very easily attac edin position and held there, it only being necessary to remove it or at the cap in position to secure the motor in lace. The belt housing chamber has litt e if any tendency to accumulate or receive dust'laden air and when the design is such'as to permit it, the holes about the motor shaft will admit enough air to keep the bearing and the belt housing clean. Where the handle and conduit are one and the same, it is necessary that the handle conduit should be pivotally attached to the frame or casing.
