Aug. 17, 1954 c. J. WESTERMAN DEVICE FOR USE IN ARTIFICIAL INSEMINATION Filed Dec. 5, 1952 INVENTOR. CYRIL J. WESTERMAN Patented Aug. 17, 1954 UNITED STATES PATENT OFFICE DEVICE FOR, USE IN ARTIFICIAL INSEMINATION 3 Claims. 1

The object of my invention is to provide a device for use by animal breeders and more particularly by hog breeders.

The art of artificial insemination has been successfully practiced by breeders of horses and cattle, but not successfully by breeders of hogs, and it is the object of my invention to provide a device that comprises a soft, pliable inner liner within a rigid outer enclosure and employing air pressure to permit the soft, pliable inner liner to assume the shape and contour in close contact with the organ of the male, and the application of heat applied to the soft, pliable inner liner to correspond with the natural temperature of the vagina of the female during the venereal act.

Hitherto, the artificial insemination of hogs has not proven satisfactory with the devices thus far provided, due to the particular shape of the male organ. The device described, illustrated and claimed herein provides an artificial vagina that is so constructed that it will consummate the venereal act to a completion and will accumulate the full volume of semen for propagating purposes where it may be retained in a fecund condition for use in artificial impregnation and semen from selected and proven male hogs may be suitably conditioned and held under controlled conditions which are well known in the art.

Obviously, the veterinarian will employ the proper sterile tubes and guns for introducing the semen taken from my device into the vagina of the female and when the proper sterilized tubes are employed the bull: supply of semen will not be contaminated.

The device is simple in construction, easily manipulated manually and is designed primarily for sanitary efficient performance.

Other and further objects of my invention will become more apparent as the description proceeds when taken in conjunction with the drawing, in which Figure 1 is an outside view of the assembled device, and

Figure 2 is a fragmentary longitudinal crosssectional view of the assembled device.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character Hi, shows a tubular enclosure constructed of semirigid material, such as rubber or the like. This tubular enclosure is open at both its ends and has an air inlet H extending through its wall. The inlet I! may be provided with a valve (not shown) or it may be made of pliable material having a self-opening and closing portion. There is a tubular water inlet shown as l2 having a sealing means l3 which may be a stopper made of any suitable material.

An inner liner or tube I4, constructed of a soft, pliable material such as is commonly referred to as latex is shown longitudinally suspended within the outer tube ill and has its ends l5 and I5 folded over the open edge of the tube In and retained in close contact with the outer peripheral surface of the tube It by means of elastic bands shown as it and I6 which are made of rubber or the like.

A pliable bag member I! open at one end and closed at the other end I8, is constructed of a pliable material and has its open end expanded and slidably placed over the band it holding the open end of the inner liner it. The elastic construction of the bag ll makes it an air tight and liquid tight seal with the liner I l thereby constructing a continuous enclosure open at only one end 19.

For the protection of the pliable bag I1, I show a tubular member 263, open at both ends and having one end 2| in close contact with the expanded portion of the bag ll and the other open end 22 permitting the closed end l8 of the bag IT to protrude therefrom.

When in use, warm liquid corresponding to the body temperature of the vagina of the female, is forced into the tubular opening [2. This liquid will be disposed between the tube It and the inner liner Hi. When the male organ is inserted into the liner [4 through the opening I9 air is forced through the tubular member H thereby forcing the liner 14 away from the inner surface of the tube is as shown by the dotted lines in Figure 22, causing the inner liner to be brought into contact with, and assume the contour of, the male organ and during the venereal act a constant frictional contact is maintained therewith.

After coition at the completion of the act, the semen will be deposited within the bag portion I I which may then be removed from the tube It! and single charges of semen thus collected may be parcelled out among several females by use of the conventional tubes and guns as previously described, thereby reducing the cost of service.

While I have shown a particular construction and arrangement of the component parts constituting my device, I am fully cognizant of the fact that many changes in the form and configuration of the component parts may be made without effecting the efficiency of the device and I reserve the right to make such changes as I may deem necessary or convenient without departing from the spirit of my invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:

1. A device of the character described colprising, a cylindrical outer shell open at both ends, a pliable inner tube open at both ends, said inner tube disposed longitudinally Within said outer shell and having its open endslcontacting the open end of said outer shell, a tubular air inlet member, a tubular liquid inlet member, said tubular members extending through thewvall of said outer shell, in combination with a bag member, said bag member being of pliable material open at one end and closed at the other end, the open end of said bag member encircling the outer edge of one end of said outer shell and inner tube assembly, means for retaining the open end of said bag member onto one end of said outer shell, a guard member of semi-rigid material, said guard member openat both ends and of a diameter larger than said bag member, one end of said guard memberattached tothe end of said outer shell at the point of attachment of said bag member to said shell.

2. A device of the character described comprising in combination, a tubular outer shell of semi-rigid material, said outer shell open at both ends, a pliable inner tube of a smaller diameter disposed longitudinally within said outer shell, said inner tube open at both ends and having its ends contacting the open end of said outer shell thereby .iorming an enclosure between the outer surface of said inner tube and the inner surface of said outer shell, which enclosure is sealed at both ends, an air inlet tube, a liquid inlet tube, both of said tubes extending through the Wall of said outer shell of said enclosure, a bag member open at one end and closed at the other end, the open end of said bag member attached to one open end of said outer shell and inner tube assembly, means for retaining said bag member in position, and a tubular support extending over the outer surface of said bag member, said support disposed at one of its ends over the attachment of said bag to said outer shell and inner tube assembly.

3. A device of the character described, comprising an outer shell of semi-rigid material, said shell open atboth its ends, a pliable inner tube openat both ends, said inner tube longer than said outer shell and longitudinally disposed Within said shell, the open ends of said inner tube folded outwardly onto themselves over the outer surface of said outer shell at both ends, forming an enclosure between the outer surface of said inner tube and the inner surface of said outer shell andsealed at both of its ends, a pair of tubular ports extending through the wall of said outer shell and leading into said enclosure, elastic means for retaining the ends of said inner tube in position over said outer shell, in combination with a bag member closed at one end and open at the other, the open end of said bag member attached to one of the open ends of said outer shell and inner tube assembly, a tubular guard member of semi-rigid material, said guard member open at both ends and of a diameter larger than the bag member, one end of said guard member attached to the end of said outer shell at the point of the attachment of said bag member to said shell.
