Some pieces of apparatus may be more con- I'he novelty characteristic of my vinvention is veniently mounted on the legs 3 such as a dental set forth in the appended claims but the invenengine I3, a spot lamp lli, and a dental cuspidor tion itself may best be understood from the fol- I 5. The dental engine i3 is supported by a tube lowing description thereof when read in con- I6 which is mounted in bearings Il that are at- 55 y l tached to one of the legs 3. Electric conductors cuspidor I5 is supported bya rigid supply conel duit 25 and a rigid drain conduit 26. These rigid conduits 25 and 26 are mounted in ball bearings 2'I which are supported by the front wall 3 of the leg 3. Any desired type of vbearings may be used but the ball bearings 2'I permit a smooth movement of the rigid conduits 25 and 26 so that the cuspidor may be freely adjusted to and from the front wall `3 of the leg 3. The rigid conduits 25 and 2'6 are horizontally supported, one above the other, in a vertical plane and portions of the conduits are bent at right angles to form vertical sections that are provided with pivotal joints 28 and 29, whereby the cuspidor I5 may be swung in an arcuate path on a vertical axis extending through the Ajoints 28 and 29.

The rigid supply conduit 25 terminates in a valve 30 that is adapted to direct the flow of wa ter either to a small goose neck pipe 3l that fountains the water into the cuspidor I5, or to a small pipe 32 that extends to a vertical extension 26', of the rigid drain conduit 26, upon which the cuspidor I5 is seated. When the water is passed, by the valve 30, to the pipe 32 extending to the drain conduit 26', a suctionlis caused in a flexible conduit 33 extending from the valve 30 to a saliva remover 34 that may be hooked over the patients lower jaw during a dental operation.V This valve 36, and associated parts, are well known in the art and are described herein merely to show its Yadaptation to this type of Vdental cuspidor.

The free ends of the rigid conduits 25 and 26, that extend within the leg 3,'have flexible ccnduits attached thereto, such as a exible supply conduit 35 and a exible drain conduit 36. The flem'ble conduits 35 and 36 connect the cuspidor I5 with a main conduit 31 and are slightly longer than the distances therebetween, to provide a loose slack in the flexible conduits 35 and 36 that will permit the adjustment of the cuspidor I5 to and from the leg 3; The main conduit 3l enters the leg 3 at the bottom. of the rear wall thereof and comprises a flexible casing containing a plurality of flexible conduits adapted to transportwater, air, gas, and electricity, so that there will be only one connection between the unit and the wall outlets in theoperating room, whereby the unit may be moved more freely.

Other instruments and pieces of apparatus are mounted within the subcompartments 4, 5, "I, and 8 of the top compartment 2. Within the front compartment 4, for instance, may be mounted a plurality of electric instruments 20. The instruments 20 may include a small lamp that may be positioned within a patients mouth to illuminate cavities and the like, and/or any other devices that may be desirable. Within the other front subcompartment 5 a plurality of air instruments 2| may be similarly mounted.` TheseV air instruments may include. an atomizer nozzle and a small blower nozzle or the like. The elec-v with the switch panel I2.

may be segregated in the separate compartments t and 5 as described above or they may be mixed together so as to best suit the individual operator. The electric and air instruments 20 and 2l may all be supported and connected to their 'respective sources of power in substantially the same manner, as is best shown in Fig. 5, in which an electric instrument 20, such as a small lamp, is shown in detail. This electric lamp instrument 2&3 may be seated in a hollow socket 22 that is mounted on the bottom 4 of the compartment 4 in juxtaposition with an aperture 23 through said bottom d and in communication with the interior of leg 3.

A flexible electric conduit 40 is attached to the electric lamp 20 and passed through the socket 22 and aperture 23 into the interior of the leg 3 and thence up to a switch box 4I that is positioned in the rear compartment 8 and associated The electric conduit lil is provided with slack so that it hangs in a U formation within the leg 3 and will permit'the electric instrument 20 to be moved a substantial distance from its socket 22.Y

The air instruments 2| are mounted in a like manner with the exception that flexible air conduits 5i) pass from the switch box 4I, through the rear subcompartment 8, into and through the interior of the other leg 3, where it is kpermitted to hang in a like U formation, and then to said air instruments 2I. Y l

An operator may have access to the electric and air instruments 20 land 2i by opening the compartments i and 5, as indicated by broken lines in Fig. 5, by lifting up and back the hinged top l2 thereof and pulling forward the hinged front d3 thereof. The hinged top i2 and the hingedfront 53 may be held in closed position by any desired means such as a latch44. Any other desired type of entrance to the subcompartments i and 5 may be provided, the hinged top i2 and the hinged front E3 merely being shown as one means of access.

Within the subcompartment 1 in one end of the top compartment 2 may be positioned an electric heating device 45 which may be connected to the switch box 4I by conduits 46. This electric heating device is adapted to heat spray bottles and their contents and are well known in the art.

The switch box 4I, mounted within the subcompartment 8, in association with the switch control panel i2 may be eliminated if separate controls are desired on the individual instruments as previously mentioned. Some means such as a distributer, however, should be provided for di-y recting the air and electricity from Vthe main source to the various individual conduits.`

An electric wall plug 47 may be mounted in the front wall 3 of one of the legs 3. This plug 4'I may be operatively connected with the dental engine i3 and may be adapted to receive a connec.

tion from a foot control therefor, as is well known in the art.

The drawers 6 in the front of the top compartment E and the drawers 9 in one end thereof may contain any desired instruments or other articles such as drugs or the like.

` The legs 3 may be provided with hinged panels,

shown in Fig. 6ro1lers l2 may be attached di- 75;

rectly to the bottoms of the legs 3. Various types of mountings may be provided to permit movement of the unit with respect to a dental chair such as the ordinary casters 10, shown in Fig. 1, rollers 12 having flanges on one side and adapted to cooperate with tracks 13, as shown in Fig. 6, or, as shown in Fig. 7, one leg 3 may be supported by a pivotal bearing M and the other leg 3 may be supported by rollers 'l5 so that the unit may be swung about one end. These methods of mounting the unit are shown as examples but any other desired method may be used.

The operation of the unit is very simple and requires a minimum effort from. the operator. After a patient has been seated in a dental chair Tl, the unit may be moved to straddle the chair 11, as shown in Fig. 8, the subcompartments 4 and 5 may be opened to permit ready use of the electric and air instruments 2D and 2l, and the cuspidor l5 may be adjusted with respect to the leg 3 to suit the patient, whereupon all of the various instruments and apparatus will be immediately at hand and ready for use.

The valve 30 may be adjusted to fountain water into the cuspidor l5 or to create a suction in the saliva remover 34 as desired. When any one of the electric or air instruments 2D or 2| are needed, the instrument 20 or 2l may be removed from its socket 22, pulling its conduit 40 or 50 thereafter, applied to its particular operation, and then, permitting the conduit 40 or 50 to pass back again into the interior of one of the legs 3, the instrument 20 or 2| may be reseated in its socket 22.

As may be readily seen, from the above description and attached drawings, my dental operating unit is very compact and eflicient. The instruments and apparatus, and their connections, are inclosed as much as is advisable to increase the protection thereto, to promote the efciency thereof and to better the appearance of the unit as a Whole.

Although I have shown and described certain specific embodiments of my invention, I am fully aware that many modiiications thereof are possible and the present disclosure should be construed only in an illustrative sense.
