Specification of Letters Patent.

Patented Dec. 8, 1907.

Application filed March 11. 1907. Serial No. 361,759.

To all whom it may concern:

Be it known that I, FRANK E. GRISWOLD,

citizen of the United States, residing at Geneva, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Speculums, of which the following is a specification.

This invention relates to speculums, and has for its object to provide means whereby the orifices or organs of the human body may be readily examined by the practitioner, or by the patient herself.

The device comprises, speakin generally, a s'pecnlum provided with i luminati means such as an electric lamp, and atelescope or sight tube arranged at an angle to lum.-

- tended at a convenient angle to permit of the parts shown in Fig. 3.

- at l3'-thereto.

the speculum proper, and having at the joint or connection a mirror inclined at a proper angle to reflect, through the tube, the image of the parts disclosed by the specu- The sighting tube or telescope is exsame being used either by the patient.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the instrument. Fig. 2 -is a central vertical section by the attendant or thereof. Fig. 3 is a side elevation of the v speculum proper detached and adapted for use alone.

Fig. 4 1s a sectional view of the Referrin s ecifically to'the drawings, 22 indicates t e lbwer or fixed jaw of an ordinary speculum, and 10 the upper jaw hinged The jaws have rearwardly extending rods 40 and 41, th which acts as a lever handle to allow the upper jawof the speculum to be opened .or closed. A screw 42 is ivotally.'attached to the lower rod, and wor hs through a hole in the upper rod and is-provided with a nut which may be run down the screw to hold the s eculum in open position when desired. 'l he speculum bills so described project from angular tubular angle piece has at the bottom a mirror cap 9. The other receives the lower one branch of an or elbow 6 which 23 held by a removable branch of the angle piece end of a sectional telescopic sight tube 20 eyebeing e former of.

is supplied which extends through the .ho low of the lower jawand through an opening 15 in the angle piece to attachment with a binding post 14. Another bin post, 14, .connects the lower jaw with the other side of the circuit. I

The current is sup lie'd from a drybattery 50,-through the cord; 51, and the necessary switches are provided .toopen or close the circuit. A' convenient way of .closing the circuit is affordedby means of a conducting cord 52 connected toone pole of the batter and. rovided at the end with a metal ring 5 whic is in the circuit, and which may be Worn upon the finger of the operator.

the metal ring is touched to a metallic art of the lampli hted.

To enab e the instrument to be small compass the sight tube 20 joint with the angle piece 6, and ma ily put on-0r 013'. Or, if desired t especulum may be used'without the sight tube, the applieddirectly to the angle iece, butv the .sight tube is es enable a person to 'use t e device and make a personal inspection without the presence or services of another person.

he connection between the an lepiece 6 and the speculuin proper is made y attaching the fixed jaw 22 ofthe speculum to the angle piece by means .of the olt 14, whichserves 85111113086 as well as that of a binding post, as escribed. 'By removin the bolt and detaching the parts the specu lumis capable of independent use, in which event it will conveniently be turned over; as indi: cated in Figs. 3 and 4, to bring the jaw having -the electric light at the top, so that should any matter run down or leak out it will not interfere with thelight. The advantages of having an instrument capable of modifications in the ways shown is obvious.

I- claim:

1. An instrument comprising a tubular angle iece having a reflector at, the angle, a pair 0 speculum jaws one of which is fixed to one branch of the angle piece-and the other smoked in as a sli be rea 5 erases of which is hinged thereto, and a sight tube on the other branch of the angle piece.

2. An instrument comprising a pair of speculum jaws and a sight tube, connected 6 by a, tubular angle piece provided with a reflector at the angle.

.3. An instrument comprlsing a tubular angle piece having arefiec't'or at the angle, a gal! of s 'eculum jaws projecting from one ranch 0 the angle-piece and having 9 rat ing handles pro'ect' rearwardly besu e .the

angle iece, an .a 'sig t tilbprgectiiig from the ot e'r branch of thean le piece.

4. The combination with an electric lamp therein in circuitqwlth the metallic part of the speculum, .tery connected thereto,

a speculum havandia batof a circuit closer comprising a ring connected to the battery and adapted to be worn on the finger and to close the lam circuit when brought to contact with said metallic part.

5. An instrument comprising a tubular angle piece having a reflector, and a pair of speculum jaws hinged together, one of the jaws being detachably fixed to the angle piece, and said jaws having rearwardly-extending operating handles.

In, testimony whereof I ture, in presence of two witnesses. FRANK E. GRISWQLD.
