ARTHUR H. SQUIEB, OF PHILADELPHIA,
PENNSYLVANIA, ASSIGNOB OF ELEVEN- FIFTEENTHS TO THE AIR CLEANER COMPANY, A CORPORATION OF PENNSYLVANIA.
Specification of Letters Patent.
Patented June 21, 1910.
Application filed May 9, 1908. Serial No. 431,887.
To all whom it may concern:
Be it known that I, ARTHUR H. SQUIER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cleaning Apparatus; 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 the art to which it appertains to make and use the same.
This invention relates to cleaning apparatus and has for an object the provision of means which are adapted to operate for cleaning either with a suction curren or a blast current o fsair an d nleans connected with the't'aiiE for using the vacuum or compressed air and cleaning liquid singularly or in combination, as may be desired.
Vith these and other objects in view, the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.
In the accompanying drawing: Figure 1 is a side elevation of one embodiment of the present invention, certain parts being broken away. Fig. 2 is a top plan view of the structure shown in Fig. 1. Fig. 3 is a section through a baffling device, embodying certain features of the invention. Fig. 4 is a section through Fig. 8 on line 44. Fig. 5 is a detail View of the means of securing the reservoir closure in position.
Referring to the drawing by numerals, 1 indicates a base more clearly shown in Fig. 1. The base 1 may be made from any kind of strong material, but preferably out of a strip of iron. The frame 1 also is bent upward at 4 in order to permit a tank 5 to be positioned higher up or farther from the floor than the motor 6.
Mounted upon the end of frame 1 is a motor 6 which may be of any desired kind as, for instance, an electric motor or other convenient power machine, but preferably I use the electric motor and provide a switch 7 that may be thrown from one position to the other for reversing the rotation of an armature 8 of the motor for permitting a pulley 9 to be driven in either direction. A suitable nheostatrIQias provided for use in starting. Positioned adjacent to motor 6,
and preferably on top thereof, is a pump 11 that is adapted to be rotated in either direction and to be reversed whenever armature 8 is reversed. A pulley 12 is provided for pump 11 for accommodating a belt 13 which in addition to engaging pulley 12 engages pulley 9 which is moved by armature 8. By this construction and arrangement the direction of rotation of pump 11, which is prcferably a rotatory pump, is governed by the direction of the rotation of armature 8, and
armature 8 is rotated one way or the other as may be desired by varying the position of switch 7.
Connected to pump 11 is a pipe 14 that is in turn connected with tank 5. By this means either a suction current or a blast current may be used by a nozzle 15 in any desired manner, the blast being provided by pump 11 when rotating in one direction, and a suction being provided when the pump is rotated in the opposite direction, the pump being of any common and well known reversible type, and not here shown in detail. Tank 5 may be constructed in any desired way, to insure strength. A cover 16 is provided for tank 5 and is held in position by means of pivot screw bolts 17 The screw bolts 17 are pivotally mounted upon ears 18 projecting from covering 16 and are adapted to pass through ears 19 projecting from the main body portion of the tank 5. A thumb nut 20 is provided for screws 17 so that when thumb nut 20 is screwed down cars 18 and 19 will be drawn toward each other for firmly holding cover 16 in position, and for grasping or clamping firmly an elastic gasket 21 which is positioned between the main body portion of tank 5 and cover 16 for forming a tight joint therebetween. By this means cover 16 may be removed or placed in position quickly and correctly, without the exercise of extraordinary skill or care. Connected with tank 5 is a safety valve 22 of the usual and ordinary type which is adapted to relieve either inward or outward pressure after the same has risen above a certain predetermined extent or condition. Valve 22 may be regulated for relieving tank 5 at different pressures so that by the positioning of valve 22 in a certain way the operator will know that he is not operating beyond a certain tension either in the use of compressed air or suction. Connected with pipe 14 is a pipe 23 that in turn has connected thereto a water baflier 24 which is constructed with a plurality of frusto-conical members 25 and 26 through which air is forced into tank 5 or removed therefrom. The baffler operates to throw the splash water out of range of the suction. A screen 27, is mounted in member 25 so as to positively prevent any foreign substance from passing upward through pipe 23 and pipe 14 into the pump when the pump is acting as a suction pump. This screen is not absolutely necessary when using the apparatus in cleaning, but it is preferable as it is adapted to positively prevent any matter from clogging the pump. Conical shaped member 26 is secured to member 25 by means of a plurality of rods 28. Member 26 is of such a size as to extend beyond member 25, as clearly seen in Figs. 3 and 4, so that the suction current or blast current is adapted to pass between the respective supporting members 28 into the conical-shaped member 26. A comparatively small opening 29 is provided in the lower end of member 26.
Tank 5 is adapted to be partially filled with a cleaning liquid, as water 30, to any desired level, but below bafller 2 1. A suitable spigot or cock 31 is provided so as to indicate when the water in the tank has reached a suflicient level.
Positioned in tank 5, preferably centrally thereof, is a pipe 32 that has secured to the lower end thereof a disk or baffling member 33 for spreading the air and dirt as the same enters the tank, Pipe 32 is connected to a pipe 3 1 which extends to the outer surface of the tank 5 and has secured thereto a valve 35 that is preferably a three-way valve. Connected to the three-way valve 35 is a hose 36 which in turn has connected to the outer end thereof nozzle 15 which may be of any desired construction. Connected to three-way valve 35 is also a pipe 37 which passes downward and enters tank 5 at 38.
In operation when it is desired to clean an object the same may be cleaned by a blast of compressed air or by suction, or by the use of both as may be desired. In addition the object may be cleaned by the use of a cleaning liquid, as water, and then the water removed by suction, the dirt being suspended in the water and consequently being removed so that after the articlehas been cleaned by the water, and then the water removed, the article will be left cleaned and dried. In accomplishing this the water is thrown on any object, or the pump 11 is caused to force air into tank 5and force water therefrom through the nozzle 15 upon the object, the pump is stopped and then the object is scrubbed by a brush or other like article. After the scrubbing operation the pump 11 is started in a direction to cause a vacuum to be created in tank 5. Nozzle 15 is then moved over the object being cleaned, and pressed against the same, the vacuum in tank 5 will cause the water upon the article being cleaned, together with some air, to be drawn through tube 36 and discharged through tube 32 into water 30. After an article has been cleaned or a considerable surface has been cleaned as a large floor or carpet and the water 30 has become dirty the same may be easily and quickly emptied and fresh water supplied. Preferably the valve 35 is turned so that any suction created by pump 11 will cause air to pass upward to tube 36, pipe 37 and from thence to the bottom of tank 5, from which it passes upward through the water, and finally reaches the pump. This will cause the water to be stirred, and all the dirt not already suspended in the water will be suspended therein by the agitation of the waterj After the water has been thoroughly stirred the pump 11 is caused to force air through the tank 5, and thus forces all the water out through the pipe 37, hose 36, and nozzle 15, nozzle 15 having been previously placed in the sewer or other place where the discharge is desired to be made. After all the dirty water has thus been discharged nozzle 15 may be placed in a receptacle having clean Water therein, and pump 11 reversed so as to draw water into tank 5. After water has been drawn into tank 5 until the same has reached a level with cook 31, the apparatus is ready for another operation.
If it is desired to use compressed air for 1 cleaning, the tank should be cleaned of any liquid and compressed air provided for tank 5, and from thence lead to nozzle 15 for use as may be desired.
It will be observed that a complete cleaning outfit is compacted into a small space and arranged to be moved from place to place. Suitable bearing members, as wheels 6060 and 61 are provided for frame 1, for more easily moving the same, wheel 61 being adapted to act in the manner of a caster or swivel wheel, so that easy turning may be provided. Handles 6262 are also provided for use in moving or pushing the apparatus from place to place.
In assembling, the motor 6 and tank 5 with the base 1, motor 6 is preferably simply set on the rear part of the base 1, and secured thereto by any desired means, and tank 5 is set upon the front part of base 1, or if desired a plate 63 is placed upon the front part of base 1, and tank 5 is placed thereon.
After the various parts have been assembled, as shown in the drawing, and particularly in Fig. 1 of the drawing, the apparatus is in condition for operation whenever the motor is connected to a source of current.
What I claim is:
1. A cleaning apparatus comprising a tank arranged to contain a cleaning liquid, a nozzle, means connecting the tank and the nozzle, means for forcing the cleaning liquid from the tank, and means for reversing said liquid forcing means whereby a partial vacuum is created in vthe tank for drawing said cleaning liquid back into said tank.
2. A cleaning apparatus comprising a rotating pump, means for reversing the same, whereby a blast current Will be provided when rotated in one direction and a suction when rotated in the opposite direction, a
10 pipe connection with the pump, a tank in communication With said pipe, a nozzle, in communication With said tank, and means for preventing any dirt passing through the nozzle from entering said pump.
In testimony whereof I affix my signature is in presence of two Witnesses.
