SUMMARY OF THE INVENTION This invention relates to an improvement in devices for cleaning removable ceiling tile or the like which is in widespread use in the so called hung ceiling. In hospitals, nursing homes. offices, etc the present prac tice is to remove the soiled ceiling tiles, clean them by hand and replace them. Since hand cleaning is time consuming and often not satisfactory, the soiled tiles are frequently discarded and new tiles installed.
Our device permits the soiled tile to be manually fed through it where the tile is cleaned by impinging spray of a detergent cleaning liquid and dried by wiper-seals. In hospitals, nursing homes. etc, the cleaning liquid may contain a germicide. Since many tiles are made so that only the visible surface is washable and the backing is often made of fibreglass, fibre, compressed paper, compo board or the like, the device is so designed that only the washable surface is subjected to the cleaning liquid. The device saves considerable time, energy and labor and the results are superior to hand cleaning.

DETAILED DESCRIPTION Referring to the drawings in detail, and particularly FIGS. 1 and 2 the ceiling tile washing device consists essentially of a support assembly S, and a housing assembly H.
The support assembly S, is structurally sound and is made up of a framework of commercial shapes and formed sheet metal appropriately fastened together. It is mounted on fixed wheels 1 and casters 2. The sides are made of non-corrisive sheet metal appropriately bent and flanged to provide stiffness and rigidity. Access to the mechanism compartment is provided by opening hinged door 3 and hinged door 4 provides access to a storage compartment.
Mounted in the mechanism compartment are an electric motor driven pump 5, a pump by-pass regulating valve 6, a liquid filter 7, solenoid valves 8 and 9, a control panel 10, and a drain valve II. A flat working surface is provided by a top 12 and a shelf 13 with supports I4. The top 12 is flanged downward to provide stiffness and to engage the sides of the mechanism compartment. The shelf 13 is flanged upward on three sides for stiffness and also forms a drip lip, should any liquid be spilled thereon. The fourth side is arranged to drain into the catch basin 15.
The cleaning solution which is made up of water and a detergent, the detergent in the case of hospitals and nursing homes may be a germicidal type. is introduced into the catch basin 15 by pouring from any convenient container such as a bucket through the open door 16 in the housing. The catch basin I5 is sloped so as to cause flow into the drain opening where it is led to the inlet of the electric motor driven pump 5 by means of rigid tubing 17 and flexible tubing 18 made up with appropriate fittings. The high pressure cleaning liquid is conducted from the pump outlet through additional rigid tubing 17 and flexible tubing 18 with appropriate fittings to solenoid valves 8 and 9. The outlet of solenoid valve 9 is connected by appropriate tubing to drain valve 11. The outlet of solenoid valve 8 is connected to the inlet of the liquid filter 7 by appropriate rigid tubing 17 and flexible tubing 18. Rigid tubing leads from the outlet of the liquid filter 7 through a bulkhead fitting I9 and terminating in a union 20. A pump by-pass regulating valve 6 is provided across the inlet and outlet of the pump 5 to afford pressure control. The control panel 10 contains an off-on switch for the pump motor. A second switch is a single pole double throw which energizes solenoid valve 8 when in one position and energizes solenoid valve 9 when in the other. Two electric service recepticles and an electric supply recepticle are incorporated into the control panel 10. The necessary electric wiring completes the essential parts of the support assembly S.
The housing assembly H is mounted on the support assembly S and is supported by structural angles 21 (FIG. 4) which rest on the top of the support S. The four sides of the housing 22, 23, 24, 25 (FIGS. 2 and 4) extend into and engage the catch basin 15 of the support S.
As seen in FIGS. 2 and 4, the housing is made up of four vertical sides 22, 23, 24, 25 and a top, is structurally sound and made of corrosion resistant sheet metal. The front side 22 contains a hinged access door 16. The two side panels 24 and 25 are slotted at the rear near the rear panel 23. It is through these slots that the ceiling tiles are entered and ejected.
Referring to FIGS. 3 and 4, it will be seen that side panels 24 and 25 have mounted on them wiper-seal assemblies which consist of formed corrosion resistant sheet 27 and inserts 28 cemented into the channel of the formed metal 27. The inserts 28 are made of sponge rubber or similar material. These wiper-seal assemblies have slotted holes by which they are mounted on the side panels 24 and 25 by bolts and wing nuts 26. The slots provide adjustment for the different thicknesses of ceiling tile and also provide the required pressure for preventing the cleaning liquid which is sprayed on the washable face of the tile from escaping from the housing at the tile face. On ejection of the tile this wiper-seal also acts to wipe dry the cleaned face of the tile.
The tile can be inserted at either side and is pushed manually through the housing with the washable face forward. It is guided through the device by upper guide 29 and lower guide 30 so that the back side of the tile is kept in contact with the housing rear panel 23. The housing rear panel 23 is flared backward at each side opposite the slots to facilitate entry of the tile.
The housing assembly (as seen in FIG. 2) also contains a manifold made up of rigid tubing 17 and appropriate ells and tees. It is connected to the support assembly tubing at union 20 through which it is supplied with filtered high pressure cleaning liquid. The manifold has attached to it spray nozzles 31, which direct the cleaning fluid onto the washable face of the tile. This manifold spray assembly is held in place by sup port 32.
The lower guide is made to accommodate different thicknesses of tile. This is accomplished by spacers 33 (FIG. 4) which can be placed on studs 34 which are fastened to the housing rear panel 23. Spacers 33 should be added or removed so that the lower guide 30 will just touch or provide a slight pressure on the face of the tile to be cleaned when the wing nuts 36 are tightened. FIG. 6 shows a flat face view of a spacer 33.
Incorporated as part of the lower guide 30 are collars (FIG. 4) located where the studs penetrate. This is a very important part of the device, since if by chance the cleaning liquid were to get between the lower guide 30 and the tile such liquid would be drained into the catch basin 15 (FIG. 3) through the space created by the collars 35. The backing of many tiles are made of fibreglass, fibre, compressed paper, compo board of the like which loses its strength and shape if wetted. Furthermore, if the backing were to become wetted, this moisture could cause rusting of the framework which supports the tile in the ceiling and in addition could cause the tile to become rust stained.
In order to accomodate various lengths of tile (heights as inserted in the device) the upper guide 29 (FIG. 4) is adjustable relative to the lower guide 30. There is a shelf like member 37 which is held against the housing rear panel 23 by sliding shoes 38 at each side. This permits the complete upper guide assembly to be raised or lowered to accommodate the length of tile to be cleaned. The sliding shoes 38 are designed so that the friction between them and the housing rear panel 23 is sufficient to maintain any given position of the upper guide assembly. The upper guide 29 is attached to the shelf-like member 37 by bolts and wing nuts 39. The upper guide is slotted at the bolts and wingnuts 39 to provide the upper guide to be adjusted to just touch or provide a slight pressure on the face of the tile.
Fastened permanently to the shelf like member 37 is an impervious membrane of vinyl, Teflon or the like 40 extending the entire width of the inside of the housing. It passes over two rollers 41 and terminates in a weight 42. The purpose of this membrane is two fold; first, to prevent cleaning liquid from the sprays 3] to get behind the upper guide assembly where it could wet the back of the tile and secondly, to provide a barrier for preventing the sprayed cleaning liquid to escape from the openings at either side between the sponge rubber 28 of the wiper-seals and the housing rear panel 23 when the upper guide assembly is set below the maximum height.
OPERATION The desired cleaning fluid is introduced into the catch basin 15 through open door 16 by means of a bucket or other container. The lower guide is adjusted to just accommodate the tile thickness by adding or removing spacers 33 and tightening wing nuts 36. The upper guide assembly is slid up or down to accommo date the tile length. The tile is placed between the upper 29 and lower 30 guides with the washable face to the spray nozzles 31, the back of the tile against the housing rear panel 23. The upper guide 29 is adjusted so as to just touch or provide a slight pressure on the face of the tile and then locking with wing nuts 39. The wiper-seal assembly 27 should be adjusted relative to each housing side panel 24 and 25 so that the sponge rubber inserts 28 provide a slight pressure on the face of the tile and then held by tightening wing nuts 26. With the double throw switch on the control panel 10 set on RUN which closes solenoid valve 9 and opens solenoid valve 8 and the motor switch set to OFF, plug in the electric supply. Close the housing door 16 and turn the motor switch to ON. The cleaning liquid will issue from the spray nozzles 31 and impinge of the face of the tile thereby cleaning it and the dirty cleaning liquid will be collected in the catch basin 15. Other soiled tiles of the same dimension can be introduced from either side, the cleaned tiles emerging from the opposite side. The wiper-seals 28 will insure that the surface of the clean tile will emerge essentially dry. Regulating valve 6 may be adjusted to give maximum effective ness.
The pump motor should be shut off when not cleaning tile. The system may be drained by throwing the double throw switch to DRAIN which opens solenoid valve 9 and closes solenoid valve 8 and opening drain valve 11. Starting the pump will cause the cleaning liquid to issue from the drain valve.
