Application filed January 16, 1909, Serial No. 472,717. Renewed October 20, 1909. Serial No. 523,701.

T 0 all whom it may concern:

Be it known that I, WILLIAM S. SAWYER, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Irrigating- Syringes; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in speculums and essentially in the provision of an irrigating tube detachably connected thereto and so arranged that it may be held in various adjusted positions, it being common in the art at present to rigidly secure these tubes in a fixed position.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure l is a perspective view of the speculum. Fig. 2 is a central longitudinal .sectional view showing the adjustable irrigating tube connected thereto, and Fig. 3 is a sectional view on line 33 of Fig. 1.

Reference now being had to the details of the drawings by letter, A and A designate two jaws of a speculum which are of the usual shape of instruments of this nature and each jaw is provided with perforations G, in order to allow the irrigating liquid to pass therethrough. The shank portion D of one of the jaws A is hollow and tapering and is positioned substantially at an angle of seventy degrees to the length of the jaw of which it is an integral part and so shaped that a flexible tube, which may be connected to the beaded end of the shank, may not easily buckle when the instrument is in use. Integral with the jaw A are the ears F, F which are spaced apart and slightly flexible and provided with threaded register-' ing apertures.

H designates an irrigating tube which may be of any size or shape and provided with the perforated bulb H. Said tube has an integral projection K of suflicient width to engage the space intermediate said ears and is apertured for the reception of a tightening screw N which is passed through the registering threaded apertures of said ears. Said adjusting screw, which has preferably an elongated shank portion with its end milled or otherwise, has a shoulder R which is adapted to bear against the face of one of said ears and, by turning the screw still farther, cause the ears to clamp and frictionally hold the projection upon said irrigating tube in different adjusted positions. Said jaw A is provided with an integral handle 0 having an aperture 0' therein through which a screw T projects, said screw having one end angled and swiveled to the shank portion of the jaw A. A thumb nut J is mounted upon said screw and is adapted, by being screwed against the handle of the jaw A, to cause the jaws to separate and be held in any suitable adjusted position. The two jaws are mounted upon the pivots I and I and the jaw A is provided with the laterally projecting portions L forming shoulders adjacent to the pivotal portions of the jaws and contact with the edges of the jaw A when the latter are closed.

By the provision of a speculum made as shown and described, it will be noted that the irrigating tube may be conveniently detached from the jaw of the speculum by simply removing the thumb screw which engages the ears upon one of the jaws or, by loosening said thumb screw, the irrigating tube may be rocked upon the screw forming a pivot and, when in the desired position, may be so held by tightening the screw and causing the ears to frictionally clamp the integral projection of said tube.

What I claim to be new is 1. A speculum comprising two jaws pivoted together, one of said jaws having integral ears spaced apart and provided with threaded registering apertures, an irrigating tube having an integral projection positioned between said ears and apertured, an adjusting screw passing through the registering apertures in said ears and projection and designed to hold the tube in an adjusted position, as set forth.

2. A speculum comprising two jaws pivoted together, one of said jaws having integral ears spaced apart and provided with I adapted to hold the tube in an adjusted posithreaded registering apertures, an irrigating tlon, as set forth. 10 tube having an integral projection posi- In testimony whereof I hereunto aflix my tioned betweemsaid ears and apertured, an signature in the presence of two witnesses.
