'5 Claims. 7 45-15) The primary object of my invention is a dry mop cleaning device, compact, easily transportable, and highly efllcient. This application has a specific reference to a specific class of mops,

. which are specially devised and applicable to the mop cleaning of large floors in institutional buildings, where bare floors commonly prevail. These mops are narrow elongated bodies with a flexible mopping construction which is intended to cover in) broad areas. This class of mop may range from a few inches width to a number of feet in length. The handle of such a mop is at substantially right angles to the elongated extent of the mop, and ordinarily attached about the center of the mop. Other objects will appear very clearly to anyone familiar with the art.

The attached drawing illustrates an embodiment of my invention, in which Fig. 1 is an elevation of the device. Fig. 2 is a vertical section elem vation of the device. Fig. 3 is a cross section at 3-3 in the direction of the arrows.

As illustrated I0 is an elongated rectangular housing, having a base Illa extending slightly forward of the front of the housing; II are a a series of cleats vertically spaced around the inner walls of the housing; I2 is a networkpreferably wireattached to the said cleats l I, which cleats space the network l2 from the inner walls of the housing: the cleats II and the network I2 0 extend from a point adjacent the top of the housing down to a point slightly removed from the bottom of the housing; the said network l2 being open at the top and bottom, also a portion of the front to be hereinafter more definitely described.

5 l2a indicates a treatment of the network at a point where the network extends from one vertical cleat on a. wall to a vertical cleat on a wall at an adjacent angle. This is devised at each of the corner positions so that the mopping por- 40 tions of the mop shall come into close proximity at all points for the removal of gathered material from the mops. A cover I3 is hinged to the top of the housing and has shoulders l4 indented around the edges of said cover, adapted 45 to be seated in a complementary recess. l4a at the top of the housing and form a closure of the housing. A spring snap i5 is provided to tensionally press against an edge of the cover is for temporary holding of the cover in position of clo- 50 sure: It is a slide member attached to the cover [5 and the housing In to holdthe cover l3 in defined position when open. In the front of the housing I provide a slot ll extending from the top of the housing downwardly to approximately xbelow the center. This slot I! has attached at its inner edges a pair of resilient members Itpreferably of rubber compositiontheir free edges extending into the area of the slot and substantially in edge contact vertically; these elastic members l8 being rigidly held attached at the 5 inner edges of the slot by cleats IS with attaching members the network l2 being left open adjacent this slot 11, the said opening in the network extending from the top of the network downwardly to the point where the flexible elel0 ments terminate. 2| are a series of inclined cleats extending around the base Illa and the inside walls of the housing from the point where the vertical cleats II and the network l2 terminate; these cleats 2| are inclined toward a hole 22 in is the base Illa of the housing: this hole 22 has a slide 23 normally covering the same adapted to catch the weightier particles of refuse dropping down from the operation of the device and has a handle 23a external of the housing adapted to 20 pull it forward for release of the dirt fallen into the bottom of the chamber of the housing. Hingedly attached to an extension of the base Illa I provide a footboard 24 adapted to swing upward with its edge against the body of the housing for it convenient transportation, there being a spring snap arrangement 25 on the face of the housing for frictional temporary holding of the member 24, the purpose of the member 24 being to be let down when the device is standing ready for operationpermitting the operator to step upon this member 24 thus giving a certain rigidity to the entire device while he performs his mop cleansing operation hereinafter described. 26 is a wheel functioning in a bracket 21 attached to the back of the housing near the base; one of said wheels and its mounting being located at either side of the base at the rear, the wheel circumference being substantially on a line with the base and so adapted that when the footboard 24 is raised-with the intention of moving the device to a different position-by a slight tilting of the wheels the device is raised from contact with the floor and rendered propellable, a hand hold 42 being provided adjacent the top of the housing externally 45 on the back aifording the operator means of tilting the device for easy propulsion on the wheels. 28 is a horizontal slot in the back wall of the housing and some distance removed from the bottom of the base of the machine; and below the said slot 28 are a pair of brackets 29. A gasket 30 with a sot is placed to register with the slot 28 of the housing. A suction machine with its bag 3i and its nozzle portion 32 is removably seated in the bracket 29 with'its nozzle aperture 6 registering with the slot in the gasket 30 and the housing slot 38; a strap 33 attached to the housing is'adapted to extend around the suction machine housing to hold it tightly in position, the bag 3| being suspendable on a hook 34 on the rear of the housing. An outlet connection 36 is set in the rear of the housing wall having means for receiving the plug connection of the suction machine, and an outlet connection 31 in the .upper portion of the-rear of the machine is adapted to receive a plug with an electric service. Associated with the outlet member 31 is a switch member 35 so positioned that when the lid I3 is brought down to a closed position in contact with the spring snap I5 a contact is made through the medium of an electric circuit 88 extending between the outlets 36 and 31 so that when the lid is brought down to its closing position the motor of the suction machine 32 is set in motion producing a suction in the chamber of the dry mop machine: and the lifting of the cover i3 breaks the connection; the machine thus operating in suction only when the operator is using it for the operation for which it is constructed. I provide a pair of brackets 39 on a side of the machine spacedly adapted to winding thereon surplus electrical wiring, or electrical service connection, when transporting from place to place, or when set aside for nonuse. The footboard 24 hingedly attached at 40 to the extension of the base Ma is adapted to be operated for the purpose of giving greater rigidity to the whole machine when in operation, the operator stepping upon the board member 24 with one of his feet, ordinarily extending the other to the extension of Illa whereby he steadies the machine for its intended operation.

The purpose of the machine and its operation are as follows:

In the cleaning of large buildings and series of buildings, as in schools, churches, universities,

. and such like institutions it has become a sanitary the elastic members-hugging the same.

the chamber.

procedure to mop the floors with what are called dry mops. These mops are more or less a lengthened type of mop and so devised as to gather dust and dirt from the floors without creating a dust to float in the atmosphere. When the operator has gathered upon his mop'what he deems suflicient he steps up to his machine-onto the board and base in the frontand raising his mop to a practically vertical position he inserts one end of .the same through the top opening into the encircling network; the handle of the mop being inserted in the slot in contact with When the mop is fully inserted the lid is drawn down which instantly automatically starts a motor in the suction machine which produces a suction within the chamber. Then the operator reciprocatingly raises and lowers his mop, shaking it, the mopping portion of the mop slightly flicking the network walls loosens the dust and dirt from the mop so that the dust particles are taken out through the medium of the suction machine while the heavier particles fall to the bottom of This machine can be placed so that a number of mopping operators can use the said machine in as continuous process as may be desired for conserving economy of time and service. The slide covering the hole in the bottom of the machine gives an immediate release to any heavier particles of dirt not easily removedby the suction machine; The device is most economically and conveniently transportplug. lift the footboard to its locking position, graps the handle on the back, slightly tilt the machine and propel it like a hand truck to any described, a vertically elongated housing having 10 a normally closed base with a valve opening therein, and a cover a vertical slot located in an upper portion or one vertical wall of the housing and communicating with the top opening; flex-' ible members mounted one on either side of the 15 slot contacting each other at their free ends; a vertically positioned elongated foraminous member within the housing chamber spaced apart from the inside walls of the housing, said member consisting of wire of comparatively large open 20 mesh; said foraminous member extending substantially the depth of the housing and following its vertical contour; a slotted wall in the ioraminous member registering with the slot in the housing wall and communicating with the .5
