Another object of the invention is to provide a light attachment for drilling instruments.
Still another important object of the invention is to provide an attachment for drilling instruments whereby heated air and water can be supplied conveniently to the working area, without removing the burr from the mouth.
These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.
' In the drawings,
Figure 1 represents a fragmentary side elevational view of a dental drilling apparatus showing one form for heating air and water.
Figure 2 is a vertical sectional view through the water tank and heater associated therewith.
Figure 3 is a fragmentary side elevational view of a drilling instrument showing a modified form of heater.
Figure 4 is a front end elevational view of the attachment shown in Figure 3.
Figure 5 is a longitudinal sectional view through the second form of the attachment.
Figure 6 is a cross sectional view on the line S-i of Figure 5.
Figure 7 is an enlarged fragmentary longitudinal sectional view through the inner end portion of the attachment shown in Figure 3.
Figure 8 is a fragmentary longitudinal sectional view through the heating unit.
Figure'9 is a fragmentary longitudinal sectional view through the water jacket.
Figure 10 is a fragmentary side elevational view and sectional view showing the thermostatic wafer.
Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that the numeral 5 represents the usual pedestal for supporting the basin 6. cup mount 1, and fountain 8, as well as the laterally disposed and upstanding post 9 from which the jointed arm III extends and supports the drilling instrument II which holds the usual bit or burr I 2. Generally referred to by numeral I3 is the water tank and heating means, the heating means being both for the air supply and water of the tank.
The assembly It consists of the water tank l4 having the inlet pipe I! and the outlet pipe or nipple i6. Surrounding the tank I4 is the hollow 5 shell I! of insulation in which the resistance element I8 is convoluted. Annular closure rings II are provided at the ends of the shell I! for closing the same and defining a chamber for receiving air from the air supply line 2| which attaches to 10 the nipple 22 at the lower end of the shell H.
A nipple at 23 extends from the upper end of the shell ll and to this the tube 24 connects. The tube 25 from the nipple it along with the tube 24 and the conductor wires 26 extend through the 1 sheathing or flexible conduit 21 to the nozzles on the instrument ll.
Around the shell I! is the heat resisting sleeve 28 and around this sleeve is the jacket 29 of insulation. The ends of the structure i3 are pro- 20 vided with insulating coverings as shown in Figure 2.
It can now be seen that'water in. the tank I4 is heated by the coil I 0 while simultaneously air passing through the chamber I! in which the coil 25 I8 is located will be heated.
When the attachment or assembly I! is not employed, the drilling instrument attachment generally referred to by numeral 30 can be employed on the drilling instrument H. In this 30 connection, see Figures 3 to 10 inclusive. This attachment consists of the hollow core 3| of insulation provided with the end circumferential flanges 32-33. This defines a, spool-like structure and around the core 3i is disposed the sleeve 34 of heat resisting or insulating material. A hollow Jacket of tubular formation and denoted by numeral 35 is disposed around the sleeve 34 and is intended for containing water. A hollow jacket of cylindrical formation'and denoted by the i0 numeral 36 circumscribes the water jacket 35 and has the electrical heating element 3! convoluted therein. Annular closure members 38 are provided at the ends of the jacket 35. A heat insulating sleeve 39 circumscribes the shell 36 and outside of this is the cylindrical casing 40 of insulation which has its ends internally threaded for receiving the end fianges'32-43.
At the rear end of the casing 40 is an outstanding box-like structure 4| of insulation having the heat insulating lining 42. A plate 43 is provided on the inside of this box-like structure 4| and has the bracket 44 projecting therefrom, this bracket being provided with the contact 45 thereon. A second bracket 46 extends in parallel relation to the bracket 44 and carries the contact 45a. Slidably disposed through the bracket 46 is the stem M of the thermostatic wafer 48.
' The stem 4! also extends through the bracket 44 and connects to the push button 49 which is slidable through an opening in the box-like structure 4i The push button 49 is provided with the fixed collar 50 at the inner end thereof and interposed between this collar 50 and the bracket 44 is the coiled compressible spring 5|. Wires from the heating element 3'! connect to the brackets 44-46 carrying the aforementioned contacts 45-45a.
Breaking of the contact 45-451; can be retarded as the attachment is being used by simply pressing in on the button 49 which serves to keep the contacts 45-4542, in contact in spite of the tendency of the wafer 48 to expand and break the said contact.
The aforementioned water jacket 35 has the nipple 52 while the jacket 36 is provided with the outside nipple 53, these nipples 52-53 being engaged by the tubes 25-24 respectively.
The forward end of the heating shell 36 is provided with a nipple 54 to which the adjustable nozzle 55*isiconnected and while the water jacket 35 is provided with the forwardly extending nozzle 56 to which the adjustable nozzle 51 is attached and these nozzles 55-51 are provided with valvular control means 58-59 respectively.
Mounted on the casing 4|] is the light '60 and to this the aforementioned conductor 26 extends and preferably through suitable guides 6 I. Suitable clamp means on the arm section ID are provided for the cable 21 and are denoted by reference character 62.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having thus described the invention, what is claimed as new is:
1. Heating means comprising a water tank having an inlet and an outlet, an air jacket surrounding the said tank, a heating element disposed in the said jacket, an air inlet and an airloutlet for the said jacket, said water tank being of cylindrical construction and having a dental instrument receiving passageway disposed therethrough.
2. Heating means comprising a water tankhaving an inlet and an outlet, an air jacket surrounding the said tank, a heating element disposed in the said jacket, an air inlet and an air outlet for the said jacket, said tank having a drilling instrument receiving passageway therethrough.
3. Heating means comprising a water tank having an inlet and an outlet, an air jacket surrounding the said tank, a heating element disposed in the said jacket, an air inlet and an air outlet for the said jacket, and a heat insulating sleeve for the said jacket, said water tank being of jacket-like construction with a passageway therethrough for receiving a dental drilling instrument.
4. In combination, a dental drilling instrument, a water jacket disposed around the instrument, a heating unit disposed around the instrument, and a nozzle extending from the water jacket toward the chuck of the instrument,.and a jacket-like structure for receiving the heating element and defining a handle for the instrument, said lastmentioned jacket having an air inlet and an air outlet.
5. In combination, a dental drilling instrument, a water jacket disposed around the instrument, a heating unit disposed around the instrument, and a nozzle extending from thewater jacket toward the chuck of the instrument, and a jacket-like structure for receiving the heating element and defining a handle for the instrument, said lastmentioned jacket having an air inlet and an air outlet, and a nozzle connected to the air outlet of the last mentioned jacket.
