SPECULUM.

SPECIFICATION forming part of Letters Patent No. 255,756, dated April 4, 1882.

Application filed December 12, 1881. (ModeL) To all whom it may concern:

Be it known that we, WILLIAM AUTEN- RIETH, of Cincinnati, Hamilton county, Ohio, and JOSEPH M. THURSTON, of Hagerstown,

Wayne county, Indiana, have invented a new and useful Improvement in speculums, of which the following is a specification.

Our invention relates chiefly to that class of speculums known as rectum-speculums, and

[O the novelty consists in the construction and combination of the parts, as will be herewith set forth and more specifically claimed.

To more fully illustrate our invention, we will refer to the accompanying drawings, forming part of our application, in which- Figurel is a view in elevation of our speculum, showing one of the fenestrae with the slide drawn over it, so as to close same. Fig. 2 differs only from the first in that the slide is drawn from the fBHGSiItB, leaving it open. Fig. 3 is a longitudinal section of the speculum, and shows the interior of the speculum with one of the slides drawn over fenestrze. Fig. 4 is a view in cross-section taken through the cross-section taken through the line zzofFig. 3.

A is the body of the speculum. B arethe fenestrte. O is a plug of metal, which in crosssection is round, used for the purpose of keeping the forward end of the slides D in position, and acting as a guide for said slides in their lateral movement in covering and uncovering the fenestrae. This plug is stationary within the speculum, made so either by cast- 5 ing it directly to the top part or by fastening it with a pin, as shown, and maybe of any other convenient shape. It also performs another and Very important function-via, that of gently and painlessly forcing thewalls of the rectum from the fenestrze when the speculum is being withdrawn. Each slide has a pin, p, which works in a slot, 8, thus acting as a guide for the rear or lower portion of the slide in its lateral movement.

5 When it is desired to detach the slide from the speculum in order to obtain a more perfect view of the walls of the rectum, or for other reasons, it is moved so as to cover the fenestrte, when the pin 19 comes in line with the gradual tapering of the exterior prevents any great pain being experienced by the person undergoing the operation. When the insertion is completed one or more of the slides, according to circumstances, are either moved back or drawn out, as is most desirable. After the fenestrte are opened the walls of the rectum pressing against the exterior of the speculum fall into the fenestrte. This enables the operator to discover the ailment and apply the necessary relief by the syringe, or whatever mode he deems best to adopt.

As before mentioned, when the slides are removed from the fenestrae the walls of the rectum press against the exterior of the tube and fall into the opening left by the said slides.

Now, in withdrawing the speculum from the passage there is danger of the folds of the rectum which have fallen into the openings becoming bound, pinched, or injured. This, however, is prevented by the plug 0, which, as the tube is withdrawn, comes in contact with the said walls, and gently and painlessly forces them out of the fenestrte, thereby saving much annoyance and trouble. Another feature of this plug is that it acts as an interior brace to the tube when it is made of thin material, and serves to insure strength and solidity. f

The slides D, being attached to the interior of the instrument, prevent the wall of rectum 0 from pain or injury while they are being moved or drawn out, as before mentioned.

We are aware that open-ended speculums having straight sides and with exterior slides have been before proposed, and do not claim 5 such construction; but,

Having thus fully described our invention, we claim- 1. A rectum-speculum having its inserting end closed and rounded and having its outer end flaring, and provided with longitudinal openings or fenestrae, combined with interior slides capable of both lateral and longitudinal adjustment to cover and uncover said openings, substantially as described.

2. In a rectum-speculum consisting of a taperin g or straighttube with a smooth, rounded, inserting end, and with longitudinal fenestrae or openings, the plug 0, constructed as described and arranged within the tube at the upper end, whereby a guide for laterally-adjustable slides is obtained, and also a means for the painless extraction of the speculum secured, substantially as described.

3. The slides D, having their rear portion turned so as to conform with the flare of the tube, and having guide-pinsp,working in slots,

together with the lips that embrace the end of 20 the tube, and set-screws t, as and for the purpose set forth.
