Application filed Juno 9, 1904. Serial No. 211,886-

' following to be a full, clear, and exact deimprovements.

. 4 dilator, which throughout a portion of its scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

M invention relates to an improved rectal il'ator, the object of the invention being mg to provide an improved device of this character which, owing to its sha e, will be retained in proper position an not chafe or otherwise discomrrode the. user. p

A further object is to provide an improved dilator, comprising, a casing inclosing a removable battery and having a ventilatorchamber between the battery and casing and inlet and outlet ports in the casing, permit ting fi'ee escape of gases. i

A further object is to provide a removable batter for a dilator,' having an opening for the a mission of suitable liquid to increase the alvanic action of the battery;

ith these and other objects in view the invention consists in certain novel features of construction and combinations and arrange-.- ments of parts, as will be more-fully hereinafter described, and pointed out in the claims.

In the accompanyin drawip-gs, Figure 1 is a longitudinal sectiona view ustrating my 2 is a transverse sectional view. Fig. 3 is an elevation. Figs. 4 and 5 are views illustrating the casing and battery separated; and Fig. 6 is a view, partly in section and partly in elevation, showing the parts assembled.

'1 represents the casing ofmy improved length is made cylindrical, as shownat 21, and is enlarged into oval sha e at one end, as

"shownat 3. The cylindrical portion of'the metallic shell or casingis made in two. parts, separated by a ring "13 of insulating material.

" Thecylindrical end of the dilator has a hollow disk-like enlargen: ent 4 and at the center of this end is providedwitha screw-threaded sleeve 5, having an enlarged outer end 6 to form a finger-hold. T I I The battery 7 consists of a cylindrical casc g holdlng in proper formation a series of 1s zinc,-or other combination, of-metals an ab- III .8 of alternate arrangement of co vper,'-

forming a channel of duct 9 throughthe same into which acetic acid or other like sorbent material, all having central openings liquid can be inserted and be absorbed'by the disks of absorbent material and insure the one endfi's made screw-t eaded to screw into sleeve 5 and has an annular enlargement orflange 10 at its outer end-to facilitate'its turning to insert or remove the same from cas- 1. The end 'ofthe battery-within the shell or casing is electrically connected with said shell or casingby means'of the conductor 14, secured to the battery'and having sliding contact with the inner face of the shell. 3

In operation the oval'enlar ed end 3 of the dilator can be readily inserts "in the rectum and the 's hincter muscles will tightly engage the cylin 'cal portion 2 of the casing 1, the

enlargement 3 preventing outward move;

ment of the dilator, while the enlargement 4 p at the outer end of the dilator will prevent its being inserted too far into the rectum.

By constructing my improved dilator as above explained it will be observed that the. parts of the battery do not come into directcontact with the body at all, but merely sup the necessaly-electric current which 1 p y arts to. be treated makes coritact with the through the casing 1, an to prevent any injurious-eilect of the contact of this metal casing it is preferably nickel, silver, or gold plated or might be entirely of these or other like metals.

As clearly illustrated, an air or; ventilator chamber is provided between the battery and casing and an opening 11 is made in the inthe outer end or e argement 4, 'perndtting free circulation of air and escape of gases from the bowels.

' ner end of the cas" 1 andanopening 12in 7 As is well known with class of battery,
