CHARLES GABEL, OF HAWKEYE, IOWA.

VETERINARY OBSTETRICAL INSTRUMENT.

To all whom it may concern:

Be it known that I, CHARLES GABEL, a citizen of the United States, residing at Hawkeye, in the county of Fayette and State of Iowa, have invented certain new and useful Improvements in Veterinary Obstetrical Instruments, of which the following is .a specification.

This invention relates to veterinary instruments, and more particularly to obstetrical instruments.

The object of this invention is to provide an instrument of the character above described which will enable the operation to be quickly and safely performed.

Another object of the invention is to provide a veterinary obstetrical instrument which is exceedingly light in construction, yet durable, convenient in use and positive in action.

With these ends in view, I make use of certain component and cooperative parts which. I deem sufficiently improved and operative to carry out the fundamental principles of my invention, however, I wish it to be understood that I do not limit myself to the exact details of construction as shown and described, as various minor changes may be resorted to without sacrificing any of the advantages of this invention.

For a clear understanding of the merits and advantages of the invention, reference is to be had to the accompanying drawings forming a part of this specification, where- 1n:

Figure 1, is a perspective view, Fig. 2, is an enlarged detail view, Fig. 3, is a modified form, and Fig. 4, is a detail view of the modification.

Referring by numerals to the drawings, 1 represents a handle composed of two wires bent to form a loop and twisted to form an elongated shank 2, at the other end of which the res ective branches or arms 3, 4, 5, and 6, are coi ed so as to form spiral springs 7, 8, 9, and 10, with their free ends projecting upwardly and terminating in small loops or eyes 11, 12, 13, and 14. The branch or arm 3, however, is so shapedas to form-an additional arm 15, which is provided with two loops or eyes 16, and a protruding lip 17, which aids in the insertion of the instrument. Passing through the eyes 11, 12 13, and 14, is a cord 18, the respective ends of which pass through the respective eyes 16,

and extend downward parallel with the arm 15, and over two of the arms and are secured to a handle 19, by means of which the arms may be contracted.

In Figs. 3 and 4, I have shown a modification wherein the arms are provided with auxiliary spiral springs 20, having their respective e nds 21 and 22, secured to the arms in such a manner that the said arms will be normally held in a flaring or extended posi tion, they may however, be contracted by means of the cord 18, as in the form shown in Figs. 1 and 2.

Normally the arms are sprung apart, and to collapse the same it is necessary to pull down on the handle 19, to which the cord is attached, thus causing the respective arms to close up within the lip 17, and to remain rigidly in this osition so that the instrument can be rea y and safely inserted into the vagina. When the fetus is reached the cord is released whereupon the arms spring apart so as to receive the fetus, and the instrument is gently pushed in until the fetus is embraced after which the cord is pulled so as to contract the arms sufliciently to insure a firm grip, and then the instrument is pulled out by the handle and cord, as the animal labors.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an obstetrical instrument, a series of wires twisted to form a handle, each wire being wound to form a spiral spring and terminating in a diverging end, and means for contracting the ends, substantially as specified.

2. In an obstetrical instrument, a series of wires bent and twisted to form a looped handle and a shank, the respective ends of the wires being coiled to form spiral springs, said ends .projecting from said springs, and means for pionltracting said ends, substantially as speci- 3. In an obstetrical instrument, a series of wires bent and twisted to form a handle and its shank, the respective ends of the wires being coiled to form springs and projecting upward from said springs, the free ends of the wires being provided with loops, and a cord passing through said loops, substantially as specified.

4. In an obstetrical instrument, a series of wires bent and twisted to form a handle and its shank, the respective ends of the wires being coiled to form springs and projecting upward from said springs, the free ends of its respective ends to a handle, substantially tile Wires t peing 1Eprovided Wit? loops, one of as specified t e Wires eing ent so as to orm a li two loops adjacent to the lip, a cord being gassed CHARLES GABEL' through the loops With its res ective ends l/Vitnesses: passed downward parallel to are arm sup- HENRY P.
