A plate'24' is provided at the top of the block for limiting the travel of the coils and preventing them from going above the face of the block. A wire grip 25 is mounted in a. recess formed in the face portion of the upper part of the block. The wire grip is mounted for movement about vertical and horizontal axes.
The lower end edge of the upper part of the block and the upper end edge of the lowerv part of theblock are provided with. complementary teeth and grooves 28 and 27.-
The lower part 11 of the block is mounted for rotation on the reduced upper end portion of an upwardly extending shaft 30. The shaft 30 is mounted in axial alignment with the drive shaft 14 for vertical reciprocating movement. Ball bearings 31 are disposed between the lower part of the block and the surface of the reduced end portion of the movable shaft'30. An annular plate 32 is attached to the under surface of the lower part of the block for aiding in retaining the ball bearings in position, The upper central portion of the lower part of ,the block is provided with a truncated cone-shaped projecting portion 33 which is adapted to fit within a complementary recess in the lower end portion of the sleeve 13 for aiding in aligning the two parts of the block. The lower part of the block is held in position on the shaft 30 by means of a washer 34 and cap screw 35.
The under surface of the lower part of thev block is provided with a plurality recesses 36 which communicate-with axially aligned openings of reduced-size in the upper portion of the lower part of the block. Driving pins-37 having collars 40 rigidly mountedthereon are disposed within the recesses 36.. Helical springs ll'are mounted on the driving pins with their upper ends engaging the collars 40 and their lower ends engaging locknuts 42 mounted in the lower end portions of the recesses 35. The driving pins 37 project upwardly through the openings in the lower part of the block and downwardly through the openings in the lock nuts 42. In the preferred form of the apparatus, four driving pins are provided and they are so spaced that all may enter openings 22 in the flange 20 simultaneously.
Any suitable means may be provided for moving the shaft 30 to move the lower part of the block into and out of engagement with the upper part of the block. In the apparatus shown'in the drawings an air operated mechanism 43 has been provided.
A table is provided for receiving the coil of wire at the completion of wire drawing operations. The table comprises an annular plate 44 surrounding the lower portion of the lower part of the block and having an annular flange 45 depending therefrom. The annular table flange 45 surrounds an upwardly projecting annular guide member 46, which in the apparatus shown in the drawings, is stationary and formed integrally with the bearing which guides the supporting shaft 30 for the lower The table flange 45 is provided with an inwardly extending annular ridge 47 which is adapted to engage an outwardly projecting annular ridge 50 carried by the guide member 46 to limit the upward movement of the table. An annular ring 51 mounted on the innervsurface of the table flange is adapted to engage the upper surface of the annular guide member 46 to limit the downward movement of the table.
The table is provided with inwardly projecting stripper plates 52 which slide in grooves or part of the block.

The pointel end of the wire is attached to the wire grip on the upper part *of the block. During the threading operation and while the pointed end of the wire is-being attached to the wire grip, the lower part should be in its lowermost position out of engagement withthe upper part of the block. When the upper and lower parts of the block are out of engagement, the upper part of the block is capable of rotating freely on itsv supporting sleeve. When the wire has been attached to the wire grip, the lower part of the block may be moved intoengagement with the upper part of the block and the teeth of the lower part will engage the teeth of theupper part. The power is then applied, rotating the drive shaft 14 and the sleeve 13. When the openings 22 in theflange 20 carried by the sleeve 13 register with the pins 37, the pins 37 will be forced upwardly into the open ings 22, thus causing rotation of the lower part of the block. The rotary motion of the lower part of the block will be transmitted to the upper part of the block" through the teeth 26 and the drawing operation will be commenced. Atv the completion of the draw, the lower part of the block lowered and the coil of wirerproduced falls to'the table and is removed. The apparatus is then ready for the next cycle.
