UNITED STATES PATENT OFFICE.

JONATHAN R. HAMILTON, OF SIOUX FALLS,` SOUTH DAKOTA.

DILATOR.

SPECIFICATION forming part of Letters Patent No. 705,346, dated July 22, 1902.

Application filed November Z, 1901 To all whom zit mfctyconcern:

Beit known that LJoNA'IHAN RHAMILTON, a citizen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of vSou th Dakota, have invented certain new and useful Improvements in Dilators, of which the following is a specification.

My invention relates to improvements in dilators of that class in which a stream of Wa-v ter is forced into or through the device, its object being particularly to provide an improved construction of inliatable shield for the dilator.

To this end my invention consists of the features of construction and combination hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure l is a section of a rectal dilator, and Fig. 2 is a section on line x oc of Fig. 1.

In the drawings, A represents the tubular body of the dilator, provided at the inlet end with branches 2 and 3, with which branches are adaptedto be connected the tubes of a' water-circulating system. (Not shown.) I show the branch 2 provided with a valve or cock 4. I provide the dilator with an inner open-end tube 5,'one end of which projects through the branch 3 of *the "dilator andthe other end of which' extends beyond -the end; of the tubular body A, as shown. of the body portion A of the dilator is lformed with exterior threads 6 to intermesh with the threads of the extensionfbarrel 7. The body of the dilator adjacent to the threaded portion 6 is formed with a circumferential iange 8. The barrel portion 7`is'formed with a series of central openings 9.

B represents a flexible covering for the barrel 7. As shown in Fig. l, the covering or sleeve B entirely covers the barrel, the end of the sleeve having an outturned portion l0, bearing against the face of the flange 8, to prevent said flange coming in contactwith and injuring the-sensitive membranes. In order to prevent any iniiation of the ends of the sleeve B and to hold the sleeve tightly The end Serial. No. 80,862. (No model.)

upon thebarrel, I weave inthe body of the sleeve adjacent to its ends the inelastic threads ll and 12.

To permit of more convenient use, I preferably curve the dilator to bring the barrel por- .tion at substantially right angles to the inlet Hend of the dilator, as shown.

In use water is forced into the dilator through the inner tube 3, from which it passes into the extension-barrel 7. By partially or wholly closing the stop-cock fthe Iiow of the water from the extension-barrel to the branch 2 is retarded or stopped, causing the water to be forced out through the openings 9,0f the barrel to cause inationfof the loose portion of the covering, as shown in Fig. l by dotted lines. By means of the threads k11 and 12 any inflation of the ends of the covering is prevented. While I have shown a stop-cock 4, the same lis not necessary and the iiow of water may be regulated in any other desired manner.

I .claim- 1. A dilator comprising a hollow body, an inner open-end tube, an extension-barrel detachably secured to said body, said barrel being formed withvopenings intermediate of its extremities, a iiexiblecover or sleeve for said barreL'Iand an inelastic insertion in said sleeve adjacent'to its ends.

2. A'dilator, comprising a hollow body portion, an inner hollow end tube, an extensiontube detachably secured to said body portion,

said tube being provided with side openings,

an elastic sleeve inclosing said extensiontube, inelastic portions adjacent to the ends of said tube, a circumferential flange upon said body adjacent to the inner end of said sleeve, andan outturned portion upon the end of said sleeve bearing against said iange.

I n testimony whereof IA affix my signature in presence of two Witnesses.

JONATHAN R. HAMILTON.

Witnesses: J. W. Boven, R. H. `WARREN.
