clear, and 'exact description thereoi".

` laters, such as My invention relates te dilaters, and has speclal reference te electrically heated diis shown, described and claimed 'in United States Letters Patent No. 1,279,111 granted to me lon September 17, 1918.

The object of my a cheap, simple and eilicient dilater in which the electric heat giving element will be asseciated with an electric light giving construction, and thereby produce a stimulation deeper into the tissues 0i rectal anatomy than would be possible with mere heat alone.

Te 'these ends my invention consists, generally stated, ,in the nevel arrangement, construction and combination of parts, as hereinafter more specifically set forth and de-k scribed and particularly pointed out in the claims.

To enable others skilled in the art te which my invention appertains te construct and use my improved dilater, I will describe the same more fully, referring to the accompanying drawing, in which:

Figure 1 is a longitudinal section of a dilater employing my invention;

Fig. 2 is a similar section of the same, with the electric connector applied thereto for use with the lighting element only;

Fig. 3 is aflike view showing the cennecter applied for use with the heating element only; y

Fig. fi shows the same view with the con? nector applied for using both the lighting and heating element-s; and

Fig. 5 is a diagram view showing the Wiring employed.

Like symbols oi reference herein indicate like drawings.

As illustrated in the drawings, A repre sents my :'unprovedl dilater which is previded with the body 1 iaving flanges 2 and 3 adjacent its rear end and an oval or egg- `adapted to invent1on is to provide .of an insulating 'minal 12' in the nected at its rear end parts in each Aof the iigures ,of the shaped head portion 4 at its opposite end. This body 1 is formed of transparent material, such as glass, quartz or other such material, that will not deteriorate in any manner when sterilized, and is provided with a chamber er recess 5 formed within the same for the reception of the combined heat and light giving device 6, hereinafter described. This heating and lighting devijce may be of any desired ferm, and as.

shown consists ef the heating element 7 and the light giving element 8, Vwhich device is carried by a plug ermounting member 9 be-screwed or otherwise secu-red inte the rear end ofthe body 1, and vtermed material. .The heating elementv 7 is formed of a resistor, such as a wire of lresistance material, which is connected'at one end by a 'wire 10 with a wire 11 connected to a wire 10, connected to the terminal 12 inthe plug 9, and the other` end of such resistor is connected to a wire 12, which is connected at its rearv end te a tersuch as at 13, which is connected'at' one end y plug 9. The lighting ele- -ment 1s termed of a suitable wire filament,

te the connection between the resistor 7 and the wire 12a and its opposite end to the cennection between a Wire 14, which is cenwith a terminal 12 in the plug 9.

The terminals 12, 12 and 12M yond the rear face et the plug 9 and are adapted to lit within the usual recess or sockets 15 of a connector 16, which carries three cords er wire connectors suitably. positiened therein, so that when such connector engages the plug 9, one conductor 17 will be' connected to the terminal 12, one con? ducter 17 will be connected to-the terminal 12. and the other connector 17 will be connected te the terminal 12".

enit is desired te use only the iighting element 8 in the dilater A, as shown in Fig. 2, the conductors-17 and 17 in the connector 16 are connected to the terminals 12 and 12, respectively, which will allow the ,current 'te pass 'through the wires 12a and 141 and lament 13, and thereby allow `the rays of visible light trom such i'ilament to pass er penetrate through the transparent head 4 in such dllator.

extend befrom such resistor both elements l and tie When it is desired to use only lthe heating element 7, in the dilater A, as shown in Fig. 3, the conductors 17 and 17 in the connector 16 are connected to the terminals 12 and 12', respectively, vwhich will allow the current to pass through the` wires 11, 10 and 125L to the resistor 7, and thereby allow the heat through the head 4; in

the dilaters.

When it is desired to use both the light giving element 8 and the heating element?, as shown in Fig. a, the conductors 17, 17 and 17" in the connector 16 are connected to the terminals 12, 12 and`12 respectively, which will allow the current to pass through the ywires l1 and. 10 from the terminals l? and wire 12*L from. the terminals 12 to the resistor 7, and through the wires 12 and lfl; from the terminals 12 fand 12' tothe Vlilarnent trom such resistor and the rays et visible light from such ilarnent to pass through 'the transparent head fl in the dilater,

lit will be obvious to anyone skilled in the art that 'the light-giving, or heat-giving, er 8 maybe inclosed in a separate casing ot glass or other material, as is customary in incandescent lamp making, such as, isshown at 18, and if desired only the portions et said casing and body 1 and adjacent the said elements need be transparent. y

lt will also be obvious that my improved dilater may be operated from a very low current, as a very small amount of energy is used, but in case it is desired to attach a higher current, a suitable resistance may be used toV control the current,y and placed within or without the dilater, as desired'.

Various other modifications and changes in the construction and operation of my improved dilator, may he resorted to, without departing from the spirit of the invention or sacriiicing any of its advantages.

lt will thus be seen that/,the dilater can.- -be used lor. various purposes and varlous parte et the body, with substantially the same eect being obtained, and will present a cempactand beneficial device tor dilating the muscles and at the same time excite the nerves and gently stimulate the capillary blood vessels.

lt will also be seen that the use of my .13, thereby allowing the heat dilater will 'furnish a constanty heat with safety te the anatomy and the reex nerve action also .has the e'ect of stimulating through the se-called abdominal brain,I and other nerve centers, which centers will have the tendency to vbring about normal healthyY conditions, and thus relieve an aggravating cause et a number el? diseases, while the heat being produced'by a very low voltage, witl1-4 out cumbersome "design, danger from sheclr is entirely eliminated, and in mest cases one veltis sucient to produce the desired heatQ 4to'seeure by Letters .Patent is l teenies The heating and. lighting element being removable frein the casing will enable repairs and renewals of parts when. desired.
