Application filed February 3, 1930. Serial No. 425,699.

My device is primarily intended for use it in combination with a dishwashing machine and has for its primary object. the stacking of the chinaware, as plates, saucers andthe like, inorder thatthe attendant may handle the stacked articles as a stack, to thereby eliminate the individual handling of each piece as the same leaves the dishstation. The receiving station is fed downe wardly the thickness of one unit at a time as the articles passing down the chute enter the receiving station. Means is also provided for manually raising the receiving and supporting station when the same is again set for use. 1 w

The invention has for its object, the stacking of chinaware into uniform piles as the same come from the dishwashing machine,

with the receiving point, for each unit, being substantially maintained at a constant height, throughout the stacking process.

A further object of my invention consists in providing a receiving station at thedischarge end of a dishwashing machine that will receive and stack the dishes as they come from the washing machine.

A still furtherobject of my invention con,- sist-s in providing a simply constructed machine adapted to receive, and stack, the

'ehinaware as the same comes from the washing machine.

With these and incidental objects in view, the invention consists in' certain novel featnresof construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

I preferably form my device of a base 1, a pedestal 2 is disposed upon the base and upwardly extends "therefrom. A receiving head 3 is mounted upon the upper end of the pedestal and an inclined chute 4 leads into the receiving station and "down which the chlnaware 5 rides. Side walls 6and 7 maintainthe chinaware within the chute. .A

resilient bumper block 8, as rubber or felt,

isdisposed upon the inner wall of therece ving StllJlOii and agamst whichthe chinaware engages as the sameenters-the rethe form of a bell crank, is disposed within the chute and inwardly extends therein so that aseach article passes vdown the chute it is required to engage the trigger trip 9. The trip 9 is pivotally disposed upon a pin 10, the pin 10 being supported upon a lug 11, disposed upon the outsideof the wall of: the chute. A reacting element 121is securedupon its one end to the'triggertrip 9 and-- upon its oppositely disposed end to the chute wall, the same being adapted for normally maintaining the trigger trip outwardly ex tending within the chute area. A shaft 13 is journaled within suitable hearing within the side walls of the gear box 1 1.. ll'lounted upon the shaft is a pinion 15, a ratchet wheel 16 and a gear 17. A rack 18 is in registerable engagement with the pinion and eoacts therewith. A ratchet pawl 19 is in register- 19 able engagement with the peripheral toothed edge of the ratchet wheel 16 and a reacting element 20 normally maintaining the pawl in contact with the ratchet wheel. A secondary shaft 21 is ournaled within the gear box 15 14 and a pinion 22 is mounted upon the shait 21 and is in registerable engagement with and coacts with the gear 17. An air governor fan 23, is mounted upon the 21 and acts a governor to prevent the racing 9 0f the gears at each cycle of operation. A plurality of lugs 24; are disposed upon the outer surface of the gear 17 and these lugs are in registerable engagement with the locking latch 25 that is disposed upon the link 26. The link 26 is cured upon its one end to a pin 27 disposed upon the outer end of the trigger trip 9' and as each article enters the chute the same passes down the chute 4, the same contacts with and actuates i ithe trigger trip 9, and in doing so disengages the locking latch 25 from the lug 2s and the weight and gravity of the head and the stack causes the rotation of the gear train until the next succeeding lug disposes upon the outer surface 17 engages the locking latch 25 thus completing the cycle of operation. In doing so the receiving station 28 upon which the chinaware 5 is disposed is fed downwardly, a suflicient amount to compensate for the thickness of the unit of chinaware being deposited thereupon. The receiving station 28 is supported. by a sleeve 29 that is slidably disposed upon the pedestal 2. Rollers 30 and 31 are journaled upon the opposite sides of the sleeve 29 and are made to engage the pedestal column 2 to thereby lessen the friction disposed between the sleeve and column when the movement occurs. When the completed stack 32 disposed 59 upon the column is removed from the receiving station, the receiving station is again raised to starting position by the operator engaging the handle 33 disposed upon the upper end of the rack 18, in doing so the pinion 15 is rotated and likewise the ratchet wheel 16. By the reverse rotation of the ratchet wheel 16, the pawl 19 rides over the teeth disposed upon the periphery of the same.

'9 While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of 05 emhodimmt herein shown and described, as

it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow:

What I claim is:

1. In a device of the class described, in combination, a supporting column, a gear box secured to the free end of the column a receiving head secured to the gear box, a train or" gearing disposed within the gear box, a receiving station slidably disposed upon the column and register-ably aligned with the receiving head, a rack secured to the receiving station and associated with the train of gearing adapted for being manually manipulated, a chute directly aligned with the receiving head, a trip rockably disposed upo': he chute and adapted for being actuated by the articles passing down the chute, and means disposed between the trip and the train of gearing for limitin the inovement of the receiving station downwardly each time the trip is actuated.

2. In a device of the class described, in combination, a base, a supporting column upwardly extending therefrom, a gear box dis os-zed upon the free end of the column, a receiving' head secured to and supported upon the b: .e, a chute secured to the receiv ing head, a train of gearing disposed within the gear box, a receiving station slidably eispesed upon the column, manual means secured to the receiving station and associated with the train of gearing for raisingthe receiving station, and means disposed upon the chute and associated with the train of gearing for limiting the movement of the receiving station downwardly a predetermined distance wnen actuated by the articles passing down the chute.

3. In a dish stacking machine, in combination, a base, a supporting column upwardly extending therefrom, a gear box disposed upon the free end of the column, a receiving head secured to and supported upon the base, a chute secured to the receiving head, a train of gearing disposed within the gear box, a ratchet wheel disposed therein, a plurality of lugs secured in spaced relationship upon the periphery of one of the gears, a receiving station slidably disposed upon the column, manual means secured to the receiving station and associated with the train of gearing for raising the receiving suation, a bell crank trip rockably disposed upon the chute, a locking latch slidably disposed within the gear box and in registerable alignment with the lugs disposed upon one of the gears, a link connecting one end of the bell crank trip to the locking latch, and a spring for maintaining the other end of the bell crank trip in the line of the articles passing down the chute and for maintaining the locking latch disengagedly engaged to one of the lugs.
