pplioation filed lareh 2, l92. Sera Hm State ot ViTiS'COnSim-ham invented certain lnew and useful improvements in YVeterinary Surgical Instruments, ot which the following is a. description.

This invention relates to veterinary surgical instruments and has t'or its primary object to provide means for transferring the generative semen from a previously bred female animal and injectingthe same into the anterior portion of the vagina ot one or more unbred females, by which operation the male reproductive germ is so placed that by virtue of its locomotive powers it can gain entrance into the uterus and there 'fen tilize the female egg.

The present invention-is designed with a view to procuring the reproduction or' desirable species of cattle or other animals and increasing the offspring from a selected male without necessitating copulation with a large number of Jemales which would impair the vitality ot the male animal.,

For the above purpose, in one construe` tion I provide a sight tube with illuminating means at one end so that the operation may be readily observed by applying the eye to the opposite end'oiC said tube. vacuum cylinder and piston is carried by the latter end of the tube and a longitudinal tube is connected at one of its ends to said cylinder and at its other end communicates with the operative end of the sight tube and collects the semen from the vagina of the bred temale animal. The cylinder and tube connected therewith are surrounded by a jacket Within which a vacuum may be maintained to prevent devitalization of the semen a reduction of its temperature. The position of the instrument for transference ot the semen to the unbred female is reversed and the end of the tube is inserted into the vagina directly over the cervix. rEhen by operating the piston thel semen or part ot it can be ejected in close proximity to the cervix.

With the above and other objects in view, the invention consists in the improved form.I construction and relative arrangement of the several parts of the improved instrument as will be hereinaftei'inore fully described, 'illustrated in the accompanying throughout ,head having; a cen* Alight bulb 8 at the opposite side drawing and subsequently incr/rpc? t the subjoined claims.

in the drewinq whe. ed one practical Yembed tion and Vin which characters designate co the several i Fig. l is a side elevational instrument Fig. 2 a longitudinal sectional View the same:

Heren-ing in detail to the sight tube 57 et sheet metal, cylindrical, though it may be i desired cross sectional iorni. this tube is obliquely cut as side of the tube 5i a longxitudin ing tube '7` of relatively 5 all c suitably secured tc the wall tin-reo I tube 7 provides a housing;1 for the reed wi or an electric ligat bulb which in the end ci' the tube 7^ which .le adjacent to oblique end tl ci rThe opposite or' the t cylinder havingr a conci l0. piston l1 'r inder 9 and is attua-ted by neen" i553 12. The outer end o li,

forward end is closure 22.

Prior to using the instrument the piston is operated and during the inward movement thereof the nger is held-over the opening 18 s0 that air Will be drawn from the jacket into the cylinder 9. In the outward move ment of the piston air is expelled from the cylinder through the opening 18; In this manner a vacuum is finally produced within the acket.

The oblique end 6 of the tube 5, held in the position shown in F ig. l, of the drawing, is then engaged with the posterior sexual organs of the bred] female animal and the interior of this end of the tube illuminated bygneans of the lamp bulb 8. By placing the eye at the opposite end of` the tube the collection of the semen may be observed. Upon operation o-f the piston .ll the semen, or a. part thereof is drawn from the vagina into the tube 20. A art of the semen may collect in the forward, end of the cylinder 9. By creating a vacuum in the jacket, as above explained the semen contained in the tube 20 and cylinder 9 is maintained substantially at its original temperature. Preferably in transferring the instrument the jacket walls are submerged in hot water or otherwise provided with an air tight heatedl so that the temperature of the semen will not be materially reduced.

The semen is discharged into the anterior vagina of the unbred female animal by reversing the position of the. instrument in the hand and inserting the point of the tube 5 into the vagina directly over the cervix. The curved outlet end ofthe tube 20 is then at the upper side of the instrument and upon operation of the piston 11 the semen flows under pressure and, by gravity through said tube andis deposited in the vagina. The reproductive germ of the male by its locomotive aowers will then pass into the uterus and fertilize the female egg after which the development of the foetus and the enbryo takes place in the natural way in the womb. In due course birth occurs and a calf is delivered.

From the foregoing description considered in connection with the accompanying drawing the construction, manner of" use, and several advantages of the improved instru- By means of the present invention the experienced veterinary surgeon may readily carry out artificial impregnation and produce a condition of pregnancy in the female animal without that female being bred by a-male. Thus -impairing its vital powers.

Vhile I have herein disclosed preferred embodiment of the invention which [have found very .satisfactory in practical use, it

will be mainffest that the instrument is Susceptible of many modifications in the form, proportion and arrangelnent of its several parts. Therefore, I reserve the privilege of resorting .tof all such legitimate changes as may be fan-ly embodied within the' spirit and scope of the appended claims.
