The Figure 3 is a side elevation detail of the bracket also mounts the intermeshing bevwall guide device. 1 eled gear 15,and holds it against movement other than rotary movement. This gear 15 is mounted fixedly on a shaft 16, that extends also through a split bearing 17 and has a splined spur gear 18 at its lower end beneath the beams 4. This bearing 17 also serves as the upper abutment, and the gear 18 as a lower abutment for a spiral spring 19 mounted over the shaft and tending to hold the gear 18 downwardly. The upper end of the shaft 16 has a nut 20 which bears on the top of the gear 15, limiting the downward movement of the shaft 16.

The gear 18 meshes with the bull gear on the spider piston when the piston is lifted to its high position, and the spring arrangement of the shaft 16 takes up any shocks which might occur due to improper tooth engagement as the bull gear is elevated into mesh. The operator controls the motor by any desired reversing control switch which starts and stops it, so as to give the desired rotation to the spider when same is lifted up. 1

In order to give a suitable guide for stopping the rotation of the spider, and enabling its accurate location over the floor tanks, we provide for a wall guide as shown in Figures 3 and 4, A frame 21 is mounted on the wall, and mounts on its outer face a downwardly tapered channel piece 22, extending vertically.

Additional frame bars 23 oneach spider arm 2 (such arms being usually a pair of diverging T-bars) serve to mount a projecting bar 24 on the end of which is a roller 25.

When the spider is in its high position the roller clears the top of the tapered channel guide, and as the piston is lowered to bring the s ider to its operation position, the roller ri es into the wide end of the guide, and is guided by the tapered sides thereof to an exact position in the lower partof the guide. The guide is so placed that when any spider arm structure is located in the guide the carryin chains on the several arms will retain the bundles of sheets di-' rectly over the several floor tanks.

This guide device not only indicates to the operator the point. to which he must bring the spider in lifting and rotating the same, but does not come into effect until the bull gear is out of mesh with its driving pinion, and thus controls. the accuracy with which the spider sinks down to its operatin% or dipping position.

y the use of the two mechanisms in com- 7 bination we are enabled to do away with considerable manual labor, and to permit a much quicker alignment of the spider, and

also we positively maintain the alignment 1 during the dipping operation, in which the roller moves up and down in the narrower portions of the wall guide. We do not wish to confine our invention to the particular details of structure described above, and we do not wish to limit ourselves to the exact type of spider and piston structure which has been indicated in the drawings. We have advisedly omitted a showing of the chains, floor tanks, hydraulic cylinders, and the like, as these have been thereon, each adapted to carry a bundle ofarticles to be picked, so as to dip said bundles into a series of tanks arranged in a circular formation aboutithe piston as a center, a driving mechanism for the piston to revolve it, comprising a driven member on the piston, and a drivin member supported above the piston, in sue a position that only when the piston is atthe upper end of its movement, will said members come into-operative engagement.
