UNITED STATES CHARLES c. oATEY, or DUBUQUE, Iowa.

ELECTRIC CLEANING DEVICE.

Application tiled August 11, 1921.

To all whom it may concern.'

Be it known that I, CHARLES C. OATEY, a citizen of the United States, residing at Dubuque, in the county of Dubuque, State of Iowa, have invented certain new and useful Improvements in Electric Cleaning Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to whichit appertains to make and use the same.

This invention relates to new and useful improvements in cleaning machines and particularly to machines for-cleaning meat chopping-blocks, floors, or for sand-papering or dusting other surfaces.

One object of the invention is to provide a device of this character `which has an electrically driven cleaning element, the device being arranged to be pushed over the floor, chopping-block, or other surfaces to be treated.

Another object is to provide a device of this character which includes a dusting element arranged to be connected with the drive shaft and the brush of the dusting element moved over the surface to be cleaned.

Another object is to provide a device of this character which includes means for feeding a liquid to the surface to be cleaned, aud to the cleaning brush, so that the surface can be more eliciently cleaned, the material removed from the surface being thrown into a receptacle which is readily removable for emptying or destruction and replacement by a new one.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is a side elevation of a cleaning machine made in accordance with the invention.

Figure 2 is a bottom plan View of the same.

Figure 3 is a vertical longitudinal central sectional view on the line 3-3 of Figure 2.

Figure 4 is ahorizontal longitudinal Hsectional view taken on the line 4 4 of Figure 3 3, above th'e motor and brush, and through the liquid receptacle.

Figure 5 is a vertical longitudinal sectional view on the line 5-5 of Figure 4, outwardly of the worm shaft.

Serial No. 491,540.

.Figure 6 is an enlarged central sectional View showing the brush and the shaft mounting.

Figure 7 is an elevation of the duster attachment partly in section.

Referring particularly to the accompanying drawing, 10 represents a housing of suitable size and shape, and which is provided wlth a bottom wall 10 having an opening 11 formed therein. In the rear portion of the housing 10, and supported by suitable brackets 11, is an electric motor 12, having its shaft 13 extending transversely of the housing and provided with a bevel gear 14 on the outer end. In the forward portion of the housing, and at opposite sides thereof, are the socket bearings 15 and 16, which support the internally threaded members 17 and 18, respectively. Removably screwed into the members 17 and 18 are the externally threaded ends of the brush shaft 19. The member 174has a worm gear 2O which meshes with a. worm shaft 21, extending longitudinally in the housing 10, and supported in the brackets 22. One end of the worm shaft 21 has a bevel gear 23 which meshes with the bevel gear 14 of the motor shaft. The outer end of the member 18 is disposed through an opening in the side of the housing and is externally threaded for a purpose which will presently appear. On the side of the housing, surrounding the said opening, is a threaded flange 24 onto which is screwed a cap 25 for protecting the end of the member 18, when the same is not being used twith the duster which will be later referred Carried by the housing and extending longitudinally underneath the bottom thereof, are the runners 26, which serve to supportA the device in its movement over the article being cleaned. These runners are detachably secured at their lforward ends to the housing by means of the set screws 30, while they are connected at their rear ends by means of the bolts 47 which pass loosel through openings in the lugs 28 and whio are threaded within openings formed in the runners, as shown at 48. Disposed between the lugs 28 and the runners and encircling the bolts 47 are the springs 49, which noi'- mally ur e the housing and the runners apart. T e supporting runners are slightly longer than the housing and the forward ends thereof overla the lower portion of the housing. The orward portions of the runners 26 are cut away to form an opening 26 which opening registers with the opening 11 formed in the bottom of the housing and through which the bristles of the brush 19 project for action u on the surface to be treated. Hinged 'at t e rear end of the housing is a door 31 which -is arranged to close an opening 32 in the side wall of the housing, suitable fastening means 33 being provided on the door and housing for holding the door in closed position. Within the housing, directly inwardly of the opening 32, is a metal receptacle 34 having its forward end open and having disposed therewithin a removable aper or fiber container 35, the o en end of which is disposed in the open en of the receptacle. Carried by the lower side of the open end of the receptacle is a downwardly and forwardly extending scoop blade 36, the same being in position to irect the material from the brush into the container. Secured to the lower face of the forward end of the bottom wall 26 are the surface engaging rollers or casters 37.

Mounted in the housing, above the brush 19, is a liquid container 38, the lower end of which is formed with a dischar e spout 39 for delivering liquid to the brus Detachably connected to the sides of the housing 10 are the upwardly and rearwardly extending bars 40, the upper ends of which are connected by the handle bar 41, which is grasped by the operator to push the machine over the surface to be cleaned.

Adapted to be screwed onto the outer end of the member 18, when the cap 25 is removed, is the threaded socket 42 of one end of a flexible shaft 43. The other end of the shaft is arranged to be detachably secured in the socket 44 of the dusting brush 45, as clearly seen in Figure 7 of the drawings.

Carried by the upper side of the housing are the handles 46 which are adapted to be grasped by the operator when moving the device over the surface of a meat choppingblock.

1. A cleaning device including a housing, detachable supporting runners carried by the housing and formed to rovide an opening, a brush mounted wit in the housing and operating through the opening, and means for normally urging the runners and housing apart.

2.
