UNITED STATES PATENT OFFICE. f,

JOHN E. CAPs, CF CINCINNATI, oHIo.

SPECULUM.

SPECIFICATION forming partf Letters Patent No. 254,457, dated March 7, 1882.

l Application filed December 3,1881. (No model.)

To all whom it may concern Be it known that I, JOHN E. CAPs, a citizen of the UnitedStates, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Speculum, of which the following is a specication.

My invention relates to improvements in speculums for the examination of diseases of the rectum; and the objects of my improvements are to give a sliding motion to one of the blades of a bivalve-speculu In and adjust its throw or angle of inclination. I attain these objects by the mechanism illustrated in the accompanying drawings, in whichv Figure l is a perspective view of my speculum as in use. Fig. 2 is a cross-section ofthe vibrating lideut through the center ot' the thumb-screw, pivots, 85e.

The spcculum consists of the body a, handle a', and brackets c, with the hinged and pivoted parts, as shown in Fig. l. 'The body ofthe speculum is made smallerat one end, with an elongated slot cut the entire length ot' the body a. In this slot the vibrating lid b works on the pivots n, as shown in Fig. l. The larger end of the body a has two brackets, c, one on each side of the lid b. The smaller ends of these brackets come nearly together, orjust close enough to allow the nut t' to work between them, as

Y 3o shown in Fig. 2. The nut z' is hinged or pivoted on two pivots, c', so that the screw d will notbend in screwing it down, which would be the case if the nut 'i was made solid to the brackets. The lower end ofthe screw d has a groove, e', cut in it, so that when the screw is inserted in the hole in the clasp o the set-screw e is turned into the groove and prevents it from working out. By this arrangement the sliding or vibrating lid b may be raised up from the body a, so it will enlarge or elevate the parts hanging down between the sore and the outward end of the speculum, so that the sore can be operated on by looking in the body of the speculum, as shown iu Fig. l.

The lid b may be slid back and forth in the clasp o, as desired, and not interfere with its raising or lowering in any way. ,Y

Having thus described my invention, I claim the following as new and desire to secure the same b v Letters Patent:

In a bivalve-spcculum, the combination of a hinged sleeve, an upper blade-shank sliding in the same, and a set-screw working in a bracket extending upward from the lower blade for depressing the shank and elevating the sliding blade, all for the purpose set forth.

JOHN E. CAPS. Witnesses:
