(Cl. 214-11) The present invention relates to an improve an inclined runway and come to rest on a re ment vin receptacle inverting mechanisms, and ceiving platform without spilling any milk what more particularly to an improvement in can in ever. verting or “dumping” mechanisms especially »ß adapted for operation in timed relation with can washing >machines of the type ldisclosed in my Patent No. 2,023,431, dated December 10, 1935. Automatic receptacle inverting mechanisms are extensively used in the industries to perform the act of »dumping or pouring out the liquid con tents of the receptacles faster and more eflicient ly than the act can be done by hand. The mech anisms for inverting or dumping the large milk cans used to transport raw milk from the pro ducer to the receiving and distributing st-ations are typical examples of such devices, and al. though the mechanism ofthe present invention. is applicable to the inverting of various kinds of receptacles in order to automatically pour out their contents, the invention will be described with particular reference to the emptying or dumping of the large cans used in transporting fluid milk. Thereupon an oscillatory cradle picks up» the `filled can and swings it in a'vertical plane to turn the can upside do-wn thereby emptying m its contents at a higher plane into the milkV re ceiving tank, at the same time depositing the can in upside do-wn position on a> support from which the can is removed and carried into the washing machine before the next succeeding can is dumped. By so arranging the can inverting mechanism that the cradle begins its upward swing on the upward stroke of the can trans porting carriage of the washing machine the cradle is started in its upward swing slowly and gently without liability of accidentally spilling the contents of the can. And then as the car riage reaches the limit of its upward movement and starts forward the cradle carrying thev ñlled can is accelerated in movement and the contentsr 20 thereof are swiftly and neatly dumped into the ’ receiving tank. without slopping over the sides of the tank. The inverting mechanism is returned It has been pro-posed heretofore- -to provide to normal position largely under the -actio-n o-f automatic can inverting or dumping mechanisms for can washers, and there are many such in suc gravity», but in order that there may be no delay in bringing Athe cradle back to» normal position cessfulvo-peration on the market today, although resilient means put kunder tension from the can many of them are objectionable in one or more transporting carri-age is availed of to start the cradle in its downward path. Another object of the invention is to produce acan invertingmechanism of such compact con struction as to take upV relatively little ñoor space, an important desideratum in connection with many can washing machines now in opera tion in restricted quarters which do not permitl of the installation and operation of former kinds of can inverting mechanisms requiring relative ly `large floor space. In this connection the can particulars, forrexamplarsuch as spilling or slop ping out some _o-f the milk before the can reaches the point at which it is dumped or because some of the milk is spilt onto the outside of a preceding can. One object of the present invention is to pro duce a can inverting or dumping mechanism of such construction that no milk will spill or slop over the top of the can before the can is posi tively inverted or dumped into the milk receiving tank. A further object of the invention is to- produce inverting cradle is `ofsuch construction that when it returns tocan receiving position it does not 40 tion of .the can being dumped so as to avoid all interfere with the passage of the next succeed ing filled canonto vthe receiving platform. ' For this purpose the can inverting .cradle comprises two pivoted `parts which are swung outwardly as possibility of milk spilling ontol the exterior of the cradle descendsgbeingstarted in their out a can vinverting mechanism of such construction that the preceding can which has just been emptied will be removed from the sphere of ac 45 ‘ ward swing by vcontact with the upper .rounded Another object of the invention is to produce ' part of the ,can and then when the can sup, a can inverting mechanism especially adapted porting `plates of thecradle pass by the bottom the preceding can. y. for connection with and operation from actuating means functioning like the can transporting car' riage of the can washing machine disclosed in my said patent, namely, an upward, forward, end of the can swing inwardly into position ready to Vbe brought upwardly under the forward edge Y50 of the bottom of the canon the platform. . downward and backward movement.

As the rod sections |82 descend, which is during the the upper surfaces of the rolls so that the can is about half its diameter over the rear end of the downward and rearward travel of the can car riage, the spring i3! acts to turn the stop lever, platform before its lower forward edge tilts down wardly and strikes the platform.V The can then 30. holding the upper end |31 of the slot |3|l.against slides smoothly down the platform until its lower the top of the reduced'portion |28 of the rod sec tion |62 so that when the rod |02 has descended front edge comes in contact with-the abutment only a relatively short distance the stop lever has 80, >which it strikes gently without imparting been swung free of the can and is out of its way before the can starts forward on the next forward stroke of the carriage. With this construction and timing of operation, if the upper part of the can being deposited in up side down position on the rails 24 should tilt 40 forward, the upper end of the right side of the can (viewing Fig. 4) would‘strike the finger |2| and the can would be deflected by it against the opposite guide rail |20, and thereby be prevented from falling forward, it being understood that the mouth of theV can is 'prevented from sliding for ward on Ythe rails 24- by means of the stop 5|. The can would thereafter settle by gravity in up side down position on thc rails 24. In this con nection it will be observed by reference to Fig. 2 - that when the can is being deposited in upside down position on the auxiliary rails 24- the last can |38 in the row of cans supported on` the rail the bottom of the can.
