Abstract

Apparatus for operating needle to inoculate the web of a bird'"'"'s wing. An arm rocks a needle holder back and forth between a serum container and web positioner, along a path which causes the needle holder to move substantially vertically into and out of the container and web positioner. Gears cause the needle holder to pivot on the arm in response to pivotal movement of the arm, so that the needle points downwardly throughout its movement.

Claims

1. Apparatus for inoculating poultry, comprising an inoculation needle indented to retain serum applied to the needle and pointed at one end for piercing a web of a bird'"'"'s wing;

a container for liquid serum to be applied to the needle;

means to position a bird'"'"'s wing so that the web of the wing is positioned for injection by the needle;

means mounting the wing positioning means and the container in laterally spaced positions, which locate the container where it is not entered by the needle when the needle extends through the web of a wing in the wing positioning means;

means to move the needle, said moving means including needle holding means secured to the needle, movable means supporting the needle holding means, and the drive means connected to the movable means and operable to move the needle holding means back and forth along a fixed path having one end extending downwardly toward the container and its other end extending downwardly toward the position of the web of a wing in the wing positioning means; and

means to direct the pointed end of the needle downward to enter the container when said needle holding means moves downwardly along said one end of its path, and to direct the pointed end of the needle downward to pass through where the web of a wing is positioned in the wing positioning means when the needle holding means moves downwardly along said other end of its path;

means to actuate said directing means in response to movement of said movable means, whereby the drive means causes the needle to move down into and up out of the container and thereafter down and up through the web in the wing positioning means.

2. Apparatus according to claim 1, in which said path has a midway point which is between the container and the wing positioning means.

3. Apparatus according to claim 2, in which said directing means comprises a stationary gear adjacent said point, a gear fixed to the needle holding means, and a belt having teeth meshing with said gears.

4. Apparatus according to claim 1, comprising a motor connected to said drive means, and means to stop and start the motor where the needle is above the position of the web of a wing in the wing positioning means.

5. Apparatus according to claim 1, in which the serum container has an upper portion of relatively large capacity, and a lower portion of substantially less capacity below and opening into the upper portion, the lower portion forming a well deep enough to receive the indented portion of the needle.

6. Apparatus which according to claim 1, in which the wing positioning means comprises a member closely overlying the web of a wing when positioned in the wing positioning means, said member having an opening through it to allow the needle to move down to pass through the web, said opening being large enough to permit viewing through it from above, thereby facilitating observation and hence avoidance of any feather in the way of the needle which might wipe off serum on the needle before it injects a web.

7. Apparatus for innoculating poultry comprising an inoculation needle indented to retain serum applied to the needle and pointed at one end for piercing the web of a bird'"'"'s wing;

a container for liquid serum to be applied to the needle, means to position a bird'"'"'s wing so that the web of the wing is positioned for injection by the needle;

means mounting the wing positioning means and the container in laterally spaced positions which locate the container where it is not entered by the needle when the needle extends through the web of a wing in the wing positioning means; and

arm;

means connected to one end of the arm and supporting the arm for pivotal movement about said one end, said one end of the arm being positioned about midway between the container and the wing positioning means;

means secured to the needle to hold the needle;

means journaling the needle holding means on the other end of the arm;

means to rock the arm about its said one end between a first position where it supports the needle holding means over the container and a second position where it supports the needle holding means over the wing positioning means; and

means to direct the pointed end of the needle downwardly to enter the container when the arm is in the said first position, and to direct the needle downwardly to pass through the web of a wing in the wing positioning means when the arm is in its said second position.

8. Apparatus according to claim 7, in which the directing means comprises a stationary gear concentric with said means pivotally supporting said one end of the arm, a gear pivotally connected to the other end of the arm and secured to the needle holding means, and means meshing with said gears to cause the gear at said other end of the arm to turn enough when the arm rocks to constantly hold the needle substantially vertical.

9. Apparatus according to claim 8, in which the means meshing with the gears is a flexible belt trained around the gears and having teeth around its interior periphery which mesh with the gears.

10. Apparatus according to claim 7, in which said means pivotally supporting said one end of the arm is a rotatable shaft;

and comprising means securing the rotatable shaft to the arm;

a motor;

a motor shaft;

a crank fixed to the motor shaft;

a drive member reciprocable lengthwise;

means meshing together said drive member and rotatable shaft to cause the arm to rock back and forth once during each endwise reciprocation of said drive member; and

means linking the crank and said drive member to cause the arm to rock back and forth once during each revolution of the motor shaft.

11. Apparatus according to claim 10 comprising a button positioned near the wing positioning means and manually operable to start the motor, means to stop the motor, means to detect when the needle completes its movement from the serum container to said second positions above the wing positioning means, and means operable by the detecting means to actuate the motor stopping means when the needle has moved to said second position.

12. Apparatus for inoculating poultry, comprising a container for serum, means for positioning a bird'"'"'s wing with its web extending substantially horizontally, said wing positioning means comprising means to position horizontally the web of a wing in the wing positioning means, said web positioning means having an opening therethrough to permit a needle to move down through the opening to pierce a web extending across the opening, the container and the web positioning means being spaced laterally apart so that a needle extending through the opening cannot enter the container, means adapted to be secured to an inoculation needle to hold the needle, and means to move the needle holding means downwardly from a position above the web positioning means and thereby cause a needle held by the needle holding means to pass through said opening, to move the needle holding means up to withdraw a needle held by it from said opening, to move the needle holding means to a position above the container, to move the needle holding means downwardly toward and upwardly from the container for applying serum to the needle, and to move the needle holding means to return it to its said position above the web positioning means, said means for moving the needle holding means comprising a supporting structure, mounting means fixed to said structure, means pivotable about said fixed mounting means, means mounting the needle holding means to pivot on the pivotable means, and means to cause the needle holding means to pivot on the pivotable means to maintain constant orientation of the needle holding means during movement of the pivotable means about its fixed pivotal mounting means, whereby a needle held downwardly by the needle holding means is caused to continue to project downwardly during movement of the pivotable means about its fixed mounting means.

13. Apparatus according to claim 25, in which said means to cause the needle holding means to maintain constant orientation comprises a gear secured to the needle holding means, a second gear, and a belt trained around said gears.
