US. Cl. 32-22 ABSTRACT OF THE DISCLOSURE The present disclosure is directed to a self-contained mobile quick set-up orthodontic unit not requiring any external plumbing connections and which requires a single 110 v. AC conventional plug electrical lead as its only external connection. The unit has a spring mounted air compressor motor driven under pressure static control with a compressed air reservoir to maintain a volume of compressed air for a three-way syringe and to pressurize a water tank to also supply the syringe. The unit also contains a vacuum tank and means for maintaining the desired vacuum. Mobility is attained by wheel mounting the cabinet structure containing the above units.

The present invention is directed to quick set-up selfcontained mobile orthodontic units which do not require expensive plumbing connections which restrict movement or relocation of the unit in or out of the dental office.

An object of the present invention is the provision of a compact mobile self-contained unit having a reservoir of compressed air maintained at a minimum pressure and3a vacuum system for drawing off saliva and other waste material which may be emptied at the end of the day.

A further object of the invention is the provision of a spring mounted quiet compressor motor driven and subject to: pressure static minimum Pair requirements which signal the motor to drive the compressor to charge the compressed air reservoir.

Another object of the present invention is the provision in a mobile self-contained orthodontic unit of a regulatable control for the vacuum system which will enable regulation of the vacuum.

A still further object of the present invention is the provision of a self-contained pressure and vacuum system which will permit use of a three-way syringe, saliva ejector and cuspidor without external plumbing connections.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views:

FIG. 1 is a vertical longitudinal section through a device constructed in accordance with the present invention with parts broken away and parts shown in section.

FIG. 2 is a horizontal section taken on the line 2-2 in FIG. 1.

FIG. 3 is a side elevational view of the vacuum and waste system.

FIG. 4 is a perspective view of the cabinet structure of the unit of the present invention.

3,553,840 w Patented .lan.12, 1971 FIG. 5 is an electrical schematic of the electrical system of .thelpresent invention. r

Referring for the moment to FIGS. 1; and 2, the mobile self -contained'dental unit has a supportingcabinet structure ,having a base 10,, sidewalls 1'1 and 12, and end walls 13 and 14. The top of the unit has twoportions 15 and16, the portion .15 beinghin'ged at 17 to w"permit.accessrto the machinery area fromthe: top. while a door 18in sidewall 11 permits access from the side.

A motor -19 drives a compressor 20 which is spring mounted at 21 on base 10 which supplies a compressed air tank 22 through line 23. A pressure static switch 24 in line 23 will cut on the motor 19 to drive the compressor 20 to bringthe air tank 22 back up to pressure. To do this switches 25 and 26 must be closed, 25 being the master switch and 26 being the compressor switch. The compressed air tank 22 supplies three'way syringe 27 through line 28 and junction valve 29 which is in communication with water from a water tank 30. The water is supplied under pressure from line 31 coming from the air manifold 32. Water leaves the tank 30 through line 33 tow-mixing valve 29. A cut-off valve 34 in line 33 and an air valve 35 in line 31 permits isolation and hence refilling of the water tank 30.

The vacuum unit for operating the cuspidor 37 and saliva ejector 38 comprises a vacuum tank 39, a motor 40 and a manifold 41 communicating with the cuspidor 37 and saliva ejector 3,8. The waste material picked up by these units are discarded into a receptacle 41 through line 42 having a check valve 43 therein.

The electrical system is best seen in FIG. 5 and shows a volt AC plug which is adapted to be plugged into any 110 volt convenience outlet. In one leg 45 of the circuit the main switch 25 has a pilot signal light 46 in series therewith to @indicate power to the main panel 47 when the plug 44 is connected to a power source. The return leg of the circuit is lead 48. In parallel with the main power circuit is the compressor motor 19 having a switch 26 and a pressure switch 24 in series with the motor 19 so that when the switch 26 is closed and the pressure in tank falls below a pre-established value the compressor motor 19 will cut in driving the compressor to recharge the tank 22.

When it is desired to use the cuspidor and saliva ejector, the switch 49 is closed driving the vacuum pump motor 40. A rheostat 50 is in series with the motor to rapidly cause the vacuum to rise as necessary and is indicated on vacuum gage 51.

The door 18 in the side wall 11 permits access to the waste receptacle 41 which may be emptied frequently for hygienic reasons. Drawers 52 are provided at the end 14 of the cabinet for storage of orthodontic tools and sup plies.

In use this unit is highly portable since no plumbing connections with the wall or floor of a building are necessary and the unit may be quickly moved into set-up and removed from an area with a minimum of time and eifort. The unit being mounted on casters 10A permits the unit to be moved about a room. The only connection between the unit and the building in which it is placed is a quick release electrical plug 44 which may be plugged into any 110 v. AC convenience outlet.

What is claimed is: I

1. A mobile quick set-up selti-contained orthodontic unit comprising (a) a cabinet mounted on casters and having top and side openings,

(b) a motor driven air compressor spring mounted in said cabinet,

(0) a compressed air reservoir in communication with said compressor,

(d) a pressure static switch in circuit with the motor drive of said air compressor and in communication with said compressed air reservoir to maintain the pressure in the reservoir at a substantially constant value,

(e) a water supply reservoir in communication with said compressed air reservoir,

(f) a three-way syringe connected to both said compressed air and water supply through a mixing valve,

(g) a vacuum tank,

(h) a motor driven vacuum pump having a variable resistance rheostat in series with the motor to speed the motor to increase vacuum as necessary,

(i) a saliva injector and a cuspidor adapted to be connected to said vacuum tank,

(j) a waste collector removably connected to said vacuum tank and having a check valve between said vacuum tank and the collector, and

(k) an access door in said side opening to permit removal of said waste collector.
