a discharge platform or conveyor 33 and there disengaged from the hooks.
In illustrating the present invention the details of the apparatus, beyond what has been generally indicated above and what is particularized below, are irrelevant and so are not further described. For present purposes the point of importance is that at one point of the path of the chains, the chains are carried under a sprocket pair 34 and thus caused to dip the container down into and bring it up again out of an open topped tank 35 in which is a body of the degreasing liquid or vapor or both. i 7
Above the tank 35 and below the sprockets 34 is positioned a pair of rigidly supported racks 36 each positioned and oriented to engage one of the pinions 2 3 shortly after the container 26 moves down into the tank. Each rack then follows the path of the pinion at first along an asymptotic straight line and then along a concentric arc. The pinion is engaged by the rack and dragged along overit, the hooks 3| being pivotable on their attachments to the chain to permit of this The pinion rolls on the rack and thus drives the shaft agent inthe tank and also for some time after the container emerges therefrom.
- To enforce operative engagement of the pinion with the rack, a guide rail 31 is .mounted above and parallel to each rack but outside the same to be engaged by the upper side of the cam roller 25 on that end of the shaft 22. Generally, the guide rail is of the same shape and is equidistant at all points from the corresponding rack. The entrance end (righthand end'in Figs. 1, 3 and 5) is, however, curved upwardly to afford easy entrance between the guide and rack for the pinion and cam roller.
Were the guide rails 31 supported rigidly in position the arrangement would operate as designed and desired a large percentage of the time. There would, however, be occasions when al pinion would engage the corresponding rack with-the tip of one of the teeth of the pinion meeting and being pressed against one of the bars ofthe rack at just the angle at which the stress exerted is radial to the pinion. There is then no force operative to rotate the pinion and the apparatus locks, the motor stalls, and there is danger Power has to be cut oif, the housing opened and entered and the accidental locking released.
. To obviatethis difficulty the guide 31 is mounted to be able to yield resiliently away from the rack, particularly at the entrance. As here disclosed, this is accomplished by pivoting the exit end of the guide on a fixedly supported pin 38, while the entrance end of the guide is formed with a slot 39 generally radialto'the pinion when the latter is just about to engage the rack. A fixedly supported pin 48 passing through slot and normally engaged against the guide at the top of the slot supports the guide in its normal position, but leaves the entrance end of the guide free to move up, if the pinion jams, against the resilient resistance of a spring 4| to release the pinion.
The arrangement as described appears to work flawlessly for its purpose, at least so long as the containers are far enough apart on the chains so that there are never two sets of pinions between the racks and guides at one time. Should there be a possibility of there being a pinion pair and cam roller pair still in engagement just to the left of the pins 38 (Fig. 3) at the moment when a following pinion jams at the entrance,the exit end of the guide 31 instead of being'pivoted on the pin 38 may be supported thereon in the same fashion that the entrance end is supported on the pin 40. I
The embodiment herein disclosed is illustrative and may be modified and departed from variously without departing from the spirit and scope of the invention as pointed out in and limited solely by the appendedclaims.
What is claimed is:
i. In an apparatus for handling articles and having conveyor means and a container for articles and pivotable carrier means toattach the container to the conveyor means to be carried along by the conveyor whilemaking the container free to swing transversely toward and from the conveyor means, a shaft on the container and mounted in the carrier means to make the container rotatable in the carrier means, a pinion on the shaft to rotate the container, a coaxial disk on the shaft, a rack of less length than the path of the pinion and fixedly'positioned beside the path of the pinion to be engaged by. the pinion and thereby effect rotation of the container during a portion only of the travel of the container, and a resiliently yieldable guide rail mounted beside the rack to engage the disk and thereby urge the pinion against the rack when coming into engagement therewith to ensure proper meshing engagement of the teeth oflthe pinion into the intertooth spaces of the rack and avoid jams occasioned by direct abutment of a tooth of the pinion against a tooth of the rack.
2. In an apparatus for handling articles and having conveyor means and a container for articles and pivotable carrier means to attach the container to the conveyor means to be carried along by the conveyor while makingthe container free to swing transversely toward and from the conveyor means, a shafton the container and mounted in the carrier means to-make the con tainer rotatable in the carrier means, a pinion on the shaft to rotate the container; a coaxial disk on the shaft; a rack of less length than the path of the pinion and fixedly positioned beside the path of the pinion to be engaged by the pinion and thereby effect rotation ofthe container during a portion only of the travel of the container, and a resiliently yieldable guide rail pivotably mounted beside the rack to engage the disk and thereby urge the pinion against the rack when coming into engagement therewith to ensure proper meshing engagement, of the teeth of the pinion into the intertoothspaces of the rack and avoid jams occasioned by'direct' abutment of a tooth of the pinion against a tooth of the rack.
