SPECULUll/l..

SPECIFICATION forming pere of Lettere resent No. 662,830, dated November 27, 1906. Application filed June 28, 1900. Serial No. 21,970. (No model.)

To all wtont it' may concern:

Be it known that I, JOHN SKLAR, a citizen of the United States, residing at New York, (Brooklym) in the county of Kings and State of New York, have invented new and useful Improvements iu Speculums, of which the following is a specification.

This invention relates to a vaginal specu lum, which can be readily arranged or adjusted to suit requirements; and the invention resides in the novel features of construction set forth in the following specification and claim, and illustrated in the annexed drawings, in which- Figure l is a sectional side View of a speculum embodying this invention. Fig. 2 is an inverted plan view of Fig. l. Fig. 3 is a rear view ot' Fig. l. Fig. 4 shows a fork or supporting member. Fig. 5 shows a fastening screw or nut. Fig. 7 shows the members in a different position than in Fig. l.

The fork or member comprises a lower or ring part a', with shank or handle part Co2 and prongs a3. The prongs support a pivot or pins b, on which swings member c', having handle or trigger c2. The member d has a shank or handle part d2 and nose d3. The shank a2 is slotted, as seen at e, and by passing a screwfthrough this slot and to the tap or threaded boss or teat g on shank d2 the two members can be clamped or secu red together. The shank a2 has a guide or rails h and the shank d2 is gutter-shaped or made to straddle or iit to this guide, so that the'shanks c2 and d2 can slide or be adjusted longitudinally with respect to one another, but are kept alined when shank d2 engages guide h. The shanks can be secured together either in the position shown in Fig. l, with the members c CZ in proximity to one another, or with the members held apart or separated, as seen in Fig. 7, in which latter position one member can be used alone, as when it is desired to press only one side or lip of the part under examination. In either position of Fig. l or Fig. 7 by loosening the fastening f the shanks a2 d2 can be slid or adjusted one along the other and xed in required position. The slot c allows screw f to slide with shank d2 when this screw is properly loosened. To set the shanks from the position shown in Fig. l to that shown in' Fig. 7 or the reverse, the

Fig. 6 shows a shank or handle.

screw f must of course be removed or loosened sufficiently to allow shank d2 to come o its straddle or engagement with guide or rails h at the sides of slot e. The nose cl3 is formed integral with shank (Z2, this shank being pressed or hollowed to form the nose, but without perforating or breaking through the material. The 'screw tap or teat g on shank d2 is exten ded or pressed inward' or toward shank Ca2, so as not to form an outer roughening or projection, which would be objectionable to the touch. In other words, the hand of the operator does not come in contact with the tap g when handling the instrument.

What I claim as new, and desire to secure by Letters Patent, is-

l.,A speculum comprising members with handle-shan ks, one of the Shanks having rails for adj ustably engaging the other shank, said second shank being made to straddle the rails substantially as described.

2. A speculum comprising members with Shanks, one of the shanks having a slot e and rails 71, at the sides of the slot and the other shank being adapted to slide on or adjustably engage the rails, and a screw-fastening eX tended through the slot and made to connect the Shanks substantially as described.

3. A speculum comprising members with shanks, one of the shanks having guide-rails,

and the other shank being made to straddle and slide on the guidera-ils, and ascrew-fastening for the members substantially as described.

4.. A speculum comprising members with shanks, one of the shanks having rails, and the other shank being made adjustable and reversible on the rails, and a fastening for the Shanks substantially as described.

5. A speculum comprising members with Shanks, one of the Shanks having rails and the other shank being made to straddle the rails and to be reversible on the first-named shank and adjustable in both its original and reversed position substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN SKLAR.
