Square axial aperture in which a square shaft69 fits loosely, and the head blocks and their wormsare' arranged in alinelnent on the overhead arm and the square shaft 69 extends across and throu h and beyond both worms. Consequently t e worms of vboth head blocks are rotated in unisora afn'd the levers 61 engage both pins 62 at the same time and swing the lower'ends of the fingerblades out from the plates at the same time.

- The finger blades are returned into their'slots on the backward roke of the levers 61 by an expansive spring 70 whichis mounted on a pin 71 that extends loosely through an aperture formed through the finger blade and is threadedinto the plate =65. r

l The shaft 69 and the worms are rotated by a train of gearing in thefollowing manner: 5

The pinion 55 on the upper end ofthe solid shaft 37 meshes with one end of a rack bar 72, the opposite end of which meshes with a pinion 73 that is secured on the end of a shaft '74, the opposite end of which is provided with a bevel gear 7 5"that meshes with a bevel gear 76 on the end of the shaft (59.

whereby the Worms 58 are turned in unison,

I LThe plate .65 of each head bloek has a vertical reciprocal movementvimpartedto it of about a half inch stroke, which movement is efiected in the following manner: A link-7 7 is iivotally at one end to each plate a y a, pin 78 that extends-loosely through [an aperture in the finger blade and isthreadled into theplate, and the opposite end of this link. is pivotally conneoted'at one end to a, lever 79, the opposite end of which fits 3 on a square shaft 80 that is mounted in sleeve bearings rotatablyv jburnaled iii ljbearing's 81 that are "formed on the hea'd block (see Fig. 4).
