SURE-LEGAL INSTEQULIIENT.

Application filed June 5, 1935:.

v. of this invention is to supply in. Mn .1. to facilitate the labor of physicians when inc ing examinations to" determine the coiulitions of subjects or patients, the instrument being specially designed for obstetrical work and to overcome nearly 21s practicable the ni'inoyence and discomfort generally experienced ehlte both by the subject and the physician or veterinaria-u'i during the examination.

The invention consists of the novel features, details of construction and combinations of parts which hereinafter will be more particularly set forth, illustrated in the accompanying drawings end pointed/out in the appended claims.

Referring to the drawings forming a part of the specifications: Figure 1 is a side view of an instrument embodying the invention parts being broken away to show more cl ly the r lative arrangement of the co ig elements. Fig. 2- is strensvcrse n on the line 2-2 of Fig. 1 looking in .ction ol? the arrow. Fig. is a cross on the line of Fig. 1 looking to right as indicated by the arrow. 1 r spondingend like parts are referred the following description and indiin all the views of the drawings by he some reference characters.

The instrumentcoruprises essentially two perts it and E, the part A being designated s cilzitor because ft its function and the part B referredto hereinafter as the body since it supports the adjunctive part,

-1e dietor A is of less diameter and size the body end is arranged at an obangle to said body for convenience of The dilator comprises essentially two parts light tube 1 and a reflecting tube 2, the latter being of larger diameter end pro vided st outer end with a lens 3. tubes 1 and are placed side by side enveloped by means of e sheath or l, which closes the spaces formed bethe two tubes and prevents any foulthe instrument and enables the some dily and Specification of Letters latent.

two tubes 1 and 2 are of substantially equal length so that their outer ends come about flush. A lens 5 1s provlded at the outer end oi the light tube 1. A lens 6 is fitted to the outer end of: the sheath or casing l. and is jointed thereto so as to present a smooth joint which. will prevent retention of any matter and avoid injury to tissues or membrenes.

The body 8 comprises a telescope 7, a. con ductor tube 8 and a battery case 9. The parts 7, 8 and 9 are protected by means of esheeth or casing 10.

An illuminetor 11 is located at the juncture of the light tube 1 and the conductor tube 2 so as to shed rays of light through the light tube upon the port to be cxzuuincd. A reflector 12 located in the rear of the illuminutor ll gathers-end throws the rays of light through the tube 1.. The illuminutor 11 is preferably of the electric type and consists of an incandescent lamp receiving current from the battery located in the case 9 by means of electric conductors 18.

A circuitclosure 14 is located near the inner end of the battery case and comprises a push button which may be pressed inward when it desired to complete the circuit to below the object lens 16 in line with the refleeting tube 2 so as to receive the object rays and reflect the some to the part 17 and the letter in turn reflecting the same to the lens 16 and telescope to the eye-piece thereby admitting of proper inspection of the part to be examined as will be readily understood.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the coustrcclion and of the method of operation will be readily apparent to those skilled in the art to which the invention a 'n crtains, and while I have described the principle of operation of the invention, toget ier with the device which I now consider to be the best elnbcdiment thereof, l desire to have it understood that the device shown is merely illustrative and that such changesmay be made When dean obtuse angle thereto, said dilator consisting of a light tube and a reflecting tube and said body comprising a telescope and a conductor tube, an illuminator located at the ,juncture of the light and conductor tubes, and complemental reflectors located at the "juncture of the reflecting tube and telescope so as to reflect the object rays from the reflecting tube through the telescope.

2. In an instrument of the character described, comprising a body portion and a dilator arranged at an obtuse angle thereto, said dilator consisting of a juxtaposed light and reflecting tubes having lenses at their outer ends, a sheath inclosing the two tubes, and a lens at the outer end of the sheath and protecting the outer ends of the said tubes and the lenses thereof. g

3. In. an instrument of the character-described, the combination of a' dilator comprising juxtaposed light and reflecting tubes, an illuminator for shedding rays of light goes through said light tube, com'plemental' re-- 3 tube. dilator at one end of the body arranged at 4:. The herein described surgical instrument comprising a dilator and a body having a relatively obtuse angle arrangement, the dilator consisting of light and reflecting tubes provided at their outer ends with lenses, a sheath .inclosing said tubes and. provided at its outer end with a lens, said body comprising a telescope, a conductor tube and a battery case, the parts being inclosed by means of a sheath, an electric illuminator located at the inner end of said light tube,

'complemental reflectors at the inner end of said reflecting tube, the telescope having its inner end arranged to receive the 0b ectrays from said reflectors, and means for closing the circuit through the electric illuminator.

In testimony whereof I aflix my signature in presence-of two Witnesses.
