Feb. 5, 1935. J. A. BAILEY DEVICE FOR POISONING RODENTS Filed NOV. 28, 1933 Patented Feb. 5, 1935 Q I JohnAmity Bailey, Willow's, cam. ,A pn'aetn November 2s, 933,seri lf v jvomias I 3 Claims.

This invention relates to a device for poisoning rodents.

An object of the invention is the construction of a simple and efficient device for quickly and easily placing poisoned grain in the holes or burrows of rodents.

Another object of the invention is the construction of a device which is provided with a novel nozzle on its outer end, whereby when the device is thrust into a hole or burrow, and pressure placed upon the device, a quantity of poisoned grain will be quickly deposited'where the animal can easily feed thereon.

A still further object of the inventionis the construction of a device comprising in combination a tube with a readily-detachable container at its outer end and at its inner end with a slidable spring-press nozzle. I

With the foregoing and other objects in View, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Fig. 1 is a perspective View of a device constructed in accordance with the present invention, showing same in a discharging position.

Fig. 2 is an enlarged fragmentary vertical sectional view of the discharge end of the device.

Fig. 3 is a sectional view taken on line 33, Fig. 2, looking in the direction of the arrows.

Fig. 4 is a sectional view taken on line 44, Fig. 2, looking in the direction of the arrows.

Referring to the drawing by numerals, 1 designates a detachable container which is screwed into the threaded mouth 2 of the outer funnel portion 3 of the comparatively long pipe or tube 4. The container 1 is employed for receiving the poisoned grain; it is usually filled before being screwed into mouth 2.

The tube 4 is closed at its outer end 5 (Fig. 2). This tube is provided on its side with a discharge outlet 6. Within tube 4 is a closure disc 7 contiguous to the outer end of outlet 6. End 5 and disc 7 produce a compartment 8 in tube 4. A

sliding sleeve-like nozzle 9 is on the outer end of tube 4. This nozzle is provided with a discharge outlet 10 which is adapted to register with outlet 6 for permitting poisoned grain to be discharged from the device, as at 11, Fig. 1.

Normally the nozzle 9 is closed by reason of the following structure. A bolt 12 is placed in the end 5 with its head 13 incompartment 8. A spiral spring 13 is around bolt 12 with its inner positing a suflicient amount of grain in the hole end pressing against end 5 and its outer end pressing against washer 14; washer 14 is mounted upon the outer threaded end of bolt 12. A nut 15 is on the outer threaded end ofbolt 12, against I washer 14, within nozzle 9. A second nut 16 is 5 on bolt .12. Nut 15 tightly engages the closed end 17 of nozzle 9, within said nozzle, and nut 16 tightly engages the outer face of end 17. The bolt 12 slides upon end 5 with its head 13 movable Within compartment 8. 7

After the container 1 has been loaded with the poisoned grain and screwed into position as shown in Fig. l the operator is ready to proceed to place the grain.- in the holes, burrows, etc., of the. I rodents. He quickly thrusts the outer nozzled end 15 of the device into the*hole,-pressing downwardly upon the same, which will cause a deposit of poisoned grain, asillustrated 111mg. 1. I have found from extensive use that my device works efficiently and I that an operator can speedily deposit poisoned grainin a great many holes in a short time.

Ihave'destroyed rcdents, by use of my device, in a relatively shorttime, over a great area of land.

By reason of the novel spring-press nozzle only grain is discharged while the operator presses downwardly upon the device; a single jab of the-device is needed for quickly de- 30 or burrow for the animal or animals residing therein.

Persons using my device never have to touch the poisoned grain, nor can poison dust get into the eyes.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawing, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended'claims.

What I claim is:

1. In a device of the class described, the combination of a tube closed at its outer end, said tube provided in its side with an outlet, a closure disc in said tube contiguous to the outer end of said outlet, said closed end. of the tube and said disc producing a compartment, a sliding sleeve-like nozzle on the outer end of said tube, said nozzle provided with an outlet adapted to register with the outlet of said tube, a sliding bolt extending through the said closed 66 end of the tube with the bolt head in said compartment, said bolt extending at its outer end through the outer end of said nozzle, a washer on said bolt within said nozzle, a spiral spring in said nozzle around said bolt with its inner end pressing against the closed end of saidtube and its outer end pressing against said washer, a nut on said bolt between said washer and the outer end of said nozzle, and anut on said bolt against'the outerface of the outer end of said nozzle, substantially as, shown and described.

2. In a device for poisoning rodents, the combination of a tube closed at its outer end and provided with a discharge outlet near said end, a sliding sleeve-like nozzle entirely enclosing the outer end of said tube, said nozzle provided with a discharge outlet being adapted to register with said first-mentioned outlet, a bolt in said nozzle and fastened against movement upon the outer 1,990,262 end of said nozzle, said bolt extending into said tube, and a coil spring around said bolt in-said nozzle and normally holding said nozzle in an extended position.

3. Ina device for poisoning rodents, the-com bination ofa tube closed at its outer end and provided with a discharge outlet near said end, a sliding sleeve-like nozzle entirely closingthe outer end of said tube, said nozzle provided with a discharge outlet being adapted to register with said first-mentioned outlet, means for limiting outward sliding movement of the nozzle fastened "fixedly against movement on the outer end of said nozzle and extending through the outer end of said tube, and means on said limiting means for normally "holding said nozzle in a closed position and extended.
