Specification of Letters Patent.
Patented Dec. 6, 1921.
T 0 all whom it may concern:
Be it known that I, IRA H. SPENCER, a citizen of the United States, residing at West Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Cleaning Apparatus, of which the following is a specification.
My invention relates to that class of cleaning apparatus more especially designed for removingmaterial from floors by means of a current or currents of air, and an object of my invention, among others, is to provide an apparatus by means of which floors containing machinery or the like may be readily and effectively cleaned of material deposited thereon.
One form of apparatus embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a cleaner embodying my invention.
Fig. 2 is a view in side elevation of the same.

Fig. 5 is a view in vertical longitudinal section on plane denoted by dotted line 5-5 of Fig. 4.
Fig. 6 is an end view of my improved apparatus.
Fig. 7 is a view in section on plane denoted by dotted line 77 of Fig. 5.
My invention is especially applicable to an apparatus intended for cleaning floors of mills and factories where comparatively light material is employed for manufacturing purposes, such as is found in cotton and woolen mills, and to this end an apparatus especially designed for this purpose is illustrated in the drawings herein in which the numeral 10 indicates a case that is composed of any suitable material, preferably sheet metal, and that may be of any desired shape, said case havinga receptacle compartment 11 at its front end, preferably round in cross section, and of considerable depth and that receives a receptacle 12 having perforations mouth 15 at its lower end of substantial width, as shown herein this month being of a width substantially that of the case, the mouth narrowing into an inlet passage 16 throughthe tube 14, said inlet passage terminating in an arch-shaped delivery end located in an arch-shaped projection 17 formed on a cover 18 that is secured by a hinge -19 to close the upper end of the compartment 11 and the passage 16. -This cover may be provided with an opening closed by a sight glass 20 through which the'space within the compartment 11 and receptacle.
may be seen.
The rear part of the case is divided into motor and battery compartments 21 and 22 respectively, the'motor compartment being preferably located near the bottom of the case and containing a motor 23 that may be connected with a battery located in the compartment 22 in any suitable manner. The construction and arrangement of this battery and its connection with the motor will be readily understood by those skilled in the art and for this rea'sonfurther illustration of the battery has been omitted from the drawings herein.
A fan 24 is attached to the shaft 25 of the motor, said fan" being located in a fan chamber 26 that communicatesthrough an opening 27 with the compartment 11 and by means of which fan airais drawn, from said compartment 11 into the fan chamber. The
motor is preferably secured to a motor sup porting plate 28 closing an opening between the fan chamber and the compartment 21. The center of the opening27 and the axis of the shaft 25 are located preferably at one side of a plane passing vertically through the center of the compartments. 1. an 21 so that the volume of air will be readily directed from the fan chamber into an outlet or exhaust chamber 29 located underneath the chamber 21.
A plate 30 closes an opening between the outlet chamber 29 and the compartment 21, this plate having a port 32 by means of which, in connection with a valve to be hereinafter described, air may be admitted into the compartment 21 and out through perforations 33 in the rear wall of the compart-ment 21. Laterally opening exhaust passages 34-35 are located underneath the chamber 29, exhaust ports 437-38 opening through the wall between the chamber 29' and said exhaust passages.
A valve shaft 39 is pivotally mounted in the walls of the chamber 29 and valves 40-41 are secured to said shaft, the valve 40 controlling flow of air through the port 32 and the valve 41 controlling flow of air through the exhaust ports 37 and 38. These valves, being secured to the shaft 39, are always maintained in definite relative positions, the valve 40 having a valve port 42 and the valve 41 having a valve port 43. These valve ports are so located in the valves and the valves are so located one with respect to the other that when the valve 40 is positioned to permit flow of air into the chamber 21 the valve 41 will be positioned to prevent flow of air into either of the passages 34 or and vice-versa. The port 43 is so arranged that air may be permitted to flow simultaneously through both of the exhaust passages 34 and 35, or through one of said passages only, or through either of said passages, to a greater or lesser extent than through the other passage. As herein shown the ports 42 and 43 each comprise substantially a third of the area of the valve in which it is located, and the valves and 41 are secured to the shaft 39 so that these ports lie on diametrically opposite sides of said'shaft. The ports 37 and 38, with the dividing strip between them, each take up substantially one-third of the area within the circle defined bythe outer edges of said ports and the port 32 comprises substantially one-third of the area within the circle defined by the outer edge of said port, and this port 32 is located on the diametrically opposite side of the shaft 39 from the ports 37 and 38. It will be understood, however,-that the shape and sizes of these ports may be varied indefinitely without departing from the spirit and intent of the invention. As a means of operating the valves a rod 45 is pivotally attached to the shaft 39 and extends in a diagonal direction upwardly and out through the back of the case where it terminates in a valve operating handle 46.
A main supporting set of wheels 47 is located at about the center of the case from the front to the rear, the parts being arranged so that the greater part of the Weight preferably is in front of a plane passing vertical] through the axis of said wheels. Supporting wheels 48-49 are located respectively at the front and rear parts of the apparatus, and a handle 50 may be attached to the upper end of the case as a means for ef fecting and controlling the movement of the apparatus as a whole.
In the structure herein shown and described the battery and motor compartments are within a substantially rectangular shaped structure and the receptacle compartment is within a projection of substantially round form located in front of and secured to the rectangularly shaped part of the casing. A fender 51 in the form of a metallic band is secured to the case and serves not only to rigidly support the projection containing the receptacle chamber, but also prevents contact of the sides of the casing with machinery or other obstructions, and hence injury to the comparatively thin metallic casing is avoided.
The device is'especially applicable to the removal of light material, as cotton or wool, used in the manufacture of fabrics from the floors of mills, the apparatus being pushed along the aisles between the machinery. All of the material located in the path of movement of the apparatus Will be readily taken up through the mouth 15, and deposited in 'the basket or receptacle 12, the air passing from said basket into the compartment 11 and through the opening 27, this movement of the air being caused by the fan 24. If the valves 40 and 41 have been located, as by means of the handle 46, in the position shown in the drawings, the air will pass from the chamber 29 through the ports 37 and 38 into and out of the exhaust passages 34 and 35. This will cause the material located at each side of the path of movement of the apparatus, and usually under the machines, to be blown away from the apparatus and into the aisles adjoining that through which the apparatus isbeing moved and from which aisles the material may be readily removed by passing the apparatus along such aisles. If it be desired to blow the material from one side of the apparatus only then the handle 46 may be operated to locate the valve 41 so that such blowing action may be had out through either exhaust passage as may be desired. If it is desired not to have the material blown by the exhaust for air from the exhaust passages, then the handle 46 may be employed to locate the valves so that the ports into the exhaust passages 34 and 35 will be closed and the port into the chamber 21 will be open so that the exhaust will be through the chamber 21 and the perforations 33 in the rear wall of said chamber.
The ring 13 is im erfora-te as to that part outside of its centra opening so that all air entering the chamber'll must as through the basket or receptacle 12. he location of this basket between the inlet 15 and the fan 24 causes all of the material which it is desired to save, to be deposited within the basket, and it is not torn or otherwise in- 'ured by being carried through the fan.
ust and dirt, however, that may pass through the meshes of the basket will be carried through the fan and thus separated to a certain extent from the material deposited within the basket. The inlet tube, as to its discharge end, that is that part located within the projection 17, is disconnected from the other part of the tube simultaneously with the lifting of the cover 18 to permit removal of the basket, and this feature comprises a portion of my invention embodied in the device forming the subject matter of this case.
