ApplicationJuly' 1 9, 1946,v Serial N 68417 15 6 Claims; 1

My invention relates to an animal extermina tor of the vermin class and more particularly to the ground burrowing vermin, and has for one of: its objects, the construction of an exterminator that may be applied to or placed ina burrowformed by a. vermin, in such a way as to render the exterminator practically invisible owing to the material employed.

Another object of. the invention is to construct an exterminator from prearranged material such as thin sheet metal and a razor blade of the safety type, or improvised blade so long as the same can be made from thin metal as the blade and carrier therefor will be positioned longitudinally with the burrow, and willv provide an end view to. the vermin and not be easily discerned.

A still further object of my invention is to provide an inexpensive device wherein scraps of sheet metal or discarded safety razor blades may be employed. A further object of my invention is to arrange the parts thereof in such a wayas to maintain the device in a definite operative positionwhen placed in a bur-row. The arcuate support-will: lie in the bottom. of the burrow, conforming thereto and will avoid tipping; furthermore, on the approach of the vermin, the end of a thin razor blade; may not beobserved until closely appreached, in which instance, the impulse for the vermin is tojump thereover or crowd through, in either instance; the keen cutting blade will fatally sever the vermin when its weight isimposed upon the blade, regardless the direction of its slant, andif on theway outward, the test has proven that rats, at least, will leave the premise, apparently tc'die from loss of blood. Such an exterminator is an effectual exterminator for rats as they are inclined to become panicky.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawings forming a part of this specification, and in which like characters will apply to like parts in the different views.

, Referring to the drawings:

. Fig. 1 is an application of the exterminator in a burrow.

.Fig.v 2 isan enlarged end view of the exterminator as installed in Fig. 1.

Fig. 3 is a reduced side view of the exterminator having a pair of blades slanting towards each other.

Fig. 4 is a side view showing the blade positioned in an arcuate body, while Fig. 5 is an end view thereof.

Fig. 6 is a side view of the exterminator, show- 2 ing the installation of a blade removably carried by the support, while Fig.- 7 isan endview thereof, taken along the line Iii-Ill in: Fig. 6..

Fig. 8- is a plan view of: Fig. 6, the blade and holder therefor being removed As a more concise description of the exterminator, it will. be seen that the structure consists of a piece of sheet metal I of suitable length and width, arcuate in form with respect to cross-section to conform with an average burrow of a vermin. S'aid arcuate sheet metal is severed intermediately of its length and a transversely'ceiitered longitudinal slot 9" is provided sufficient to receive a minor length portion of a safety; razor blade 2' in'sertibl'e therein and being. supported as shown and maybe integrally secured where it passes through the sheet.

The sheet metal may be arranged with two safety razor blades, in which case, the'blad'es will slant upward and towards each other so that vermin traveling in either directionthrough its-burrow will comein' contact with the cutting edgeof the blades, which will gash the vermin sufficient to producea constant flow of its blood. In such instance, the vermin will continue to travel, moving away from the" exterminator and perhaps outward from its burrow befcrebl'eedingto death; It has been discovered that the vermin travels in either direction through its burrow and in contact with a single blade; the result is practically thesame and the impulse" of a' vermin is tomove onward quickly, severing practically the entire length ofthebowel region, whlch'is fatal to'the vermin. It is a-ls'opossible', should the vermin approach at either end of theblade, the tendency is to jump over such obstruction; and the function of the blade being similar to-that'of a dagger, sufficient laceration is performed to sever major arteries that is fatal'to the vermin.

Certain modifications have been made as described be'low; It will be understood that the" razorblades" employed in the different views are the same, and in some instances, the reinforcing means for the blade has been removed entirely, while in other views; the reinforcing; means remain and in others, p'a'rtlyloosened, but employed to' secure the blade.

In' Figs; 4 and 5', a conventional single edged blade 5 has a U-shaped reinforcing member's on its edge opposite said blades cutting edge 5'. A portion of said member 6 is turned outward from each side of the blade as at I, so that the exposed portion of the blade will extend through slot 9' in a body 8 that is arcuate in cross section while the portions of reinforcing members are turned back to lie on the convexity of the body and pressed tightly thereon. Furthermore the notch 9 in the end of the blade is placed astraddle of the metal where one end of slot 9' terminates, as a result, the blade cannot be withdrawn or varied with respect to its slant.

The blade I shown in Figs. 6 and 7 has not been altered or changed, and to secure the same in an operative position, there is provided a holder ll U-shaped in form and in which the reinforcing means I2 of the blade will slide longitudinally through the U-shaped formation, which is substantially equal in length to that of the blade, the holder and blade extending through the bottom of the arcuate body I3, while another portion of the holder is cut slantingly to form a two-ply web M to provide lips l4 passing through the body and turning outward each way thereunder, and to avoid further movement through the body, the members of the web are formed into a bead A as shown in Fig. 7, the outer projection of which lies on the inner side of the arcuate body, which gives a strong support for the upward slant of the blade. To avoid a downward rock of the .blade, it will be seen that the notch [5 will straddle the metal of an opening I6 made through the bottom as shown in Fig. 8, said opening being of sufiicient width at its longer portion to receive the lower extremity of the blade and its reinforcing, while the narrow portion is to receive the web seating therein and clinching below as above described.

Preferably the blades are removably secured to the arcuate bodies for convenience of transportation as the bodies may be nested while the blades and holders may be boxed separately, and such other modifications may be made as lie within the scope of the appended claims.

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

1. In an animal exterminator, an elongated body semi-circular in cross section and being made from thin sheet material, a safety razor blade, and a reinforcing means for said razor blade, said razor blade and said reinforcing means being carried in the concave side of the body, said blade being disposed in a plane perpendicular to a line drawn tangent to the curved outer surface of said body, the blade extending through the body at its longitudinal and transverse center, and a portion of said reinforcing means being adapted to extend through the body, said reinforcing means having a lateral bend whereby said blade is retained in the said body.

2. An animal exterminator comprising the combination of a safety razor blade and an elongated body, said body being semi-circular or arcuate in cross section and being made from thin sheet material, said safety razor blade being carried in the concave side of the body centrally thereof, one side and end portion of the blade extending through a longitudinal slot in the body as a means to support the blade perpendicular to a line forming a tangent to the exterior surface of the arcuate body.

3. An animal exterminator comprising a safety razor blade, said blade having a cutting edge and a U-shaped reinforcing element to enclose the oppositely disposed edge of the blade, and a semi-circular or arcuate casing structure to support the blade perpendicular to a line forming a tangent to the exterior surf-ace of the arcuate structure and in the concave side thereof, the casing structure having an elongated slot longitudinally thereof to receive a corner portion of the blade, and a portion of said reinforcing element being adapted to extend through the arcuate structure, said reinforcing element having a lateral bend whereby said blade is retained in said arcuate structure.

4. An animal exterminator comprising a body consisting of an elongated piece of sheet material arcuate in cross section, the concavity of which is upwardly positioned, and a razor blade having reinforcing means on one of its side edges and a notch in one of its ends, a portion of said side edge of the blade and reinforcing means extending through the body from its concave side and at the bodys longitudinal and transverse center, while the other side edge of the blade is upwardly positioned and inclined with respect to the body longitudinally, and the portion of the reinforcing means extending through the body having lateral bends adapted to coact with the notch of the blade to retain the blade from displacement.

5. In an animal exterminator, a body, a safety razor blade having one cutting edge and an edge disposed opposite to said cutting edge, a U-shaped reinforcing element embracing said opposite razor blade edge, said body having a slot adapted to receive a corner portion of said blade, and a portion of the reinforcing element received in the slot having outturned end portions extending outwardly from the sides of the blade whereby the body is engaged therewith and the cutting edge of the blade is retained in said body extending upwardly and angularly with respect to the longitudinal axis of the body.

6. The structure defined in claim 5 wherein said blade is provided with a notch extending inwardly from one of its ends adjacent the outturned portions of the reinforcing element, said blade being adapted to engage said slot by means of said notch, whereby in cooperation with the outturned portions of the reinforcing element, the cutting edge of the blade is disposed in a definite angular relation with respect to the longitudinal axis of the body.
