Patented Apr. 25, 1933 PATENT OFFICE WEBSTER I. CARPENTER, E NORFOLK, VIRGINIA FLUID TEMPERATURE MAINTAINEB Application led July 25,
This invention relatesto a fluidtemperature maintainer particularly adapted for dispositiony between a source of warm Huid supply and a dental syringe and has for its primary s objectto provide, in a manner as hereinafter lset forth, a device of such character by means of which water or air may be maintained at a given temperature while being conveyed to the syringe in order that a cavity in a sensitive tooth may be irrigated or dried by discharging thereinto a Ifluid at A body temperature.
A further object of the invention is to provide a device of the character aforesaid including a flexible, insulated support for the resistance coil wherein the support and coil have connected therewith means for securing the same in position within a tubular fluid conveyor of any type which it is desired to em loy.
further object of the invention is to provide a fluid temperature maintainer including a resistance coil floatingly mounted with re- 1930. smal no. 470.747.

In the embodiment shown, the

The length 8 said and further including a flexible conducof tubing 7 is also connected with the outlet tor leading to the resistance coil, said conduc- 'pipe 4 by means of a coupling element 10 tor being insulated from the wall of the consimllar to the coupling 8 and including an duit and from the fluid within the conduit, electric terminal 11. the insulating means for the conductor pro- In the embodiment shown, the coupling ss viding a flexible support for the resistance element 8 includes a pair of flanged plugs coil. 12 respectively inserted into'the sections of A further object of the invention is to protubing 6 and 7. Swiveled on the plugs 12 vide a fluid temperature maintainer which are a pair of internally threaded sleeves 13 9o may be connected with a source of fluid supply without re ard to the temperature of such fiuid and y means of which the fluid may be raised to'and maintained at the. temperature desired within the maintainer.
45 With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanywhich are connected together by means of a hollow plug 14k which is provided with the electric terminal 9 heretofore men-tioned The coupling 1() is of the same lconstruction as the coupling 8.. It is to be understood that the couplings 8 and 10 might be modi- 95 fied as desiredin order to connect the same with conduits of any type other than the tubing sections 6 and 7 herein disclosed.
Having one end secured to the coupling 5 ing drawing wherein is shown an embodielement 10 is a flexible conductor 15 which electrical energy to the source of extends through the section of tubing 7, couplin element 8, and section of tubing 6, the con uctor terminating in a floating end 16 extending into the handle of the s ringe 1. Encircling the conductor 15 is a exible insulating member 17, the ends of which terminate in spaced relation to the ends of the conductor.. The insulating member 17 preferably is in the form of a soft rubber tube. Coiled around the insulating member 17 is a flexible resistance coil 18, one end of which is secured as shown at 19 to the floating end 16 of the conductor, and the opposite end of which is connected with the couplin element 8. The resistance coil 18 forms t e outer peripheral surface of the heating element and is spaced from the wall of` the tubing 6. The coupling elements 8 and 10 are formed of conducting material in order that an electric current may be passed between the terminals 9 and 11 and the coil 18 and conductor 15 respectively. In the embodiment shown, the terminals 9 and 11 are connected in series with the terminals 20 of the source of fluid supply 2 by means of a pair of conductors 21, although the conductors 21 may be connected with any suitable source of electrical energy in any manner desired. Obviously when the terminals of the maintainer are connected in series with the terminals of the fluid supply as shown, the supply of electrical ener to the resistance coil 18 will be controll b the same means which controls the supp of Supp y 2- In the event that the conductors 21 are con nected with a source of electrical energy inde endently of the source of sup ly 2, a suitablieJ thermostat, not shown, may provided for controlling the supply of electrical en er to the coil 18.
en using the maintainer in connection with a supply of air, the insulatin member 17 referably will be formed of as stos.
n the operation of the maintainer, the fluid being conveyed ythrough the tubing sections 7 and 6 to the syringe 1 is maintained at the proper required temperature by the contact of the fluid with the resistance coil 18, in order that the fluid may be discharged from the s inge 1 at the same temperature at which it is discharged from the source of supply 2, irrespective of the length of time which may elapse between the time of discharge from the source 2 and syri e 1.
It is to be noticed that no specia type of tube section 6 is required in order to secure the heating element therein, and it is to be further noticed that the heating element is entirel free of connection with the wall of the tu section 6. In the event that the tube section 6 becomes damaged throu h long continued use, the same may be readi y replaced simply by disconnecting it fromV the syringe 1 and coupling element 8. The
conductor 15 will be of appropriate size to prevent any material heating of the insulatingi member 17 interiorally of the latter in or er to protect the same from deterioration. Owing to the contact of the outer face of the insulatin member 17 with the Huid within the tu section 6, the member 17 is only subjected to heat from the coil 18 substantially equal to the temperature of the fluid within the tube 6. Owing to the short, tube section 7 employed, a positive insulation is provided between the coupling elements 8 and 10, thereby preventing any possibility of a short circuit between the terminals 9 and 11.
It is thought that the many advantages of a fluid temperature maintainer in accordance with this invention will be readil apparent, and although the preferred em odiment of the invention is as illustrated and described, it is to be understood that changes in the size, sha and arrangement of parts may be resorte to, so long as auch chan es fall within the sco of the invention as 5efined in the appen ed claims.
