During rotation of will be reciprocated fingers 54, in relangers 54 on its outer end. the shaft 4I, the ngers 53 longitudinally and also the tively-stepped relation.
The beveled gear Wheel 25 has driving connection with a pair of eccentric yokes or hoops 56 and 57 that respectively operate fingers 58 and59 in synchronism with the operation of the ngers 53 and 54, the eccentrics for the fingers 58 and and 44 are pivotally.` I
59 operating in the manner shown in Fig. 6 in connection with the eccentrics for the fingers 53 and 54.
Rack ngers or rods Ell- 6l are carried by the plate l and a similar plate 62, respectvely, to hold a stack of dishes or other articles against horizontal displacement while they are being operated upon by the various fingers. As shown in Figs. 1 to 6, a stack of articles will be placed in the rack formed by the rods 60-Bl, and the articles 63 will then be deposited one-by-one upon a conveyor S4 or other suitable support.
yIn placing the apparatus in operation, the threaded sleeve will be rotated by or in other suitable manner, to adjust the nuts the worm 32m 21-28 and hence the slides l1--I8 toward or*l from one another, in accordancewith the diameters or widths of the articles to be separated* or depiled. This adjustment shifts the bearings` 23 and 24, together with their associated gear wheels 25 and 26, longitudinally of the shaft 2l and at the same time will correspondingly shift the eccentric mechanism so that the rack fingers SII- '51 and the iingers 53-54 and Sii-+59 will be brought into proper relationship to the articles.
Thereupon, the motor 22 will be set in operation torotate the shaft 2i and the eccentrics. The fingers l54 and 59 will support 'the stack until the fingers 5'3-58 have been moved toward one another in position to engage an article that is immediately above the one with which the fingers 54-59are engaged. Continued operation of the eccentrics will thenwithdraw the fingers 54--59, allowingthe lowermost dish to drop to the conveyor 64. Immediately thereafter, the mecha nism will move the fingers 54-59 into position to supportr the next fingers 53,-58 Awithdrawn to allow the ystack dishes to be moved down into engagement with the 'fingers 154-59. Thereafter, the fingers 53 and 58 will be moved into position above thev lowermost dish, and the operations continued lowermost dish and the` until all of the dishes or other articles have been discharged or depiled.
In Figs. 7, 8, and 9, I show mechanism constructed and operated in somewhat the same manner as the apparatus of Figs. 1 to 5. In this case however, the article-engaging fingers are operated in va somewhat different manner, in order to pile the dishes or assemble them in a stack. In this arrangement, iingers 66 are operated by 4an eccentric 61 in the same manner as arethek fingers 53-58, at each side of the stack'of articles. Lifting fingers 68 are provided at'each side of the apparatus, forv lifting articles 69 from arconveyor 19, one-by-one, to form a pile as in Fig. 8. i
These fingers 68 instead of being reciprocated horizontally as are the fingers 54,4 are oscillated through an arc by eccentric yokes or hoops 12 that are moved eccentrically as are the hoops 43. f The hoops have arms 13 rigidly secured thereto, these arms carrying the ngers 68. The hoops are fioatingly connected to the base plate |80, by links 15 so that during rotation of the shaft 41a and arms 13, the lingers 68 will be moved in arcuate paths downwardly and backwardly with respect to the articles and then advanced toward the articles and upwardly to lift the articles from the conveyor 18. During this cycle of movement by the arms 13, the fingers 66 will be maintained in position to support the stack of articles. As soon as the iingers 68 have moved an article upwardly against the lower end of the stack, the fingers 89 will be retracted and then .projectedtov bring themv into.. position to support thejarticlelast raised by the ng'ers B8.
It will be seen that, forfthe most part, the same lmechanism can be used to either pile or unpile articles, the principal change required being simply in thesubstituting of eccentric elements 12 for the eccentrics 43. The various piling and depiling fingers can be made of any suitable material, such as glass-covered steel pins or chromeplated metal, so'as not to mar or discolor fine vware, and vso that the fingers themselves will have longer life than would ordinary steel for example. YKAs shown in Fig. 9, dishes or the like can be piled and depiled when they are in inverted positions. ,1
I claim'as my invention:
Article-handling apparatus comprising a pair 'A lof base members that are supported on slide-ways n for adjustment toward and from each other, in
a horizontal'plane, an Yeccentric shaft 'journaledl on each base member and each provided with'a pair of eccentrics that are relativelyoifset about the axis of the shaft, yokes on the eccentrics,
horizontally-extending fingers' kpivotallyV con"-v nected to theI yokes, lguide means for the ngers," and retaining members extending upwardly from the base members, in positions to hold the articles of a stack in'relative vertical valinement, the
fingers connected to an eccentric yoke of one shaft andthe fingers 'thatare connected-'to the correspondingly mounted` eccentric yoke ofthe other l shaft being in a higher plane than-the vfingers f that'aref-c'onnected to the other eccentric yokes, and the fingers that are line 'of a stack of articles being moved toward and froml one another by their eccentrics, to
afford vertical support to a fthereby 'periodically stackzof articles, by respectively.
