lOur invention relates to a screw-type conveyor mechanism for conveying open-mouth jars or other articles from one point to another and cooperating means for washing or rinsing the interior of the articles as they are advanced bythe conveyor.
The invention provides'a horizontally disposed, continually rotating screw conveyor combined with means forpresenting the jars in upright position to the conveyor and causing them to be advanced by the rotation of the conveyor, introducing water or other liquid into jars, inverting the jars as they advance along the conveyor and thereafter reinverting the jars to upright position before they are released from the conveyor.
A 'feature of the invention relates to the variaf tion in the pitch of the spiral trough or channel in which the articles are held during their advance along the conveyor and particularly in increasing the pitch of the portion of the channel within the article-inverting zone and thereby accelerating the speed of the jars and maintaining a comparatively high speed while they are passing. through thelinverting zone. The construction permits a rapid inverting movement .of the jars during which the rinsing water is -foroeably and rapidly ejected by the combined action of centrifugal force and gravity. As the jars are completing the inverting movement, the speed is again reduced by decreasing the pitch of the spiral channelj a While the inverted jars are advancing at the reduced speed, they are subjected to a .rinsing operation by upwardly directed jets of water supplied through suitably arranged nozzles. Beyond the rinsing zoneY the pitch of the channel is again increased, causing the jars while being reinverted 'to advance at an accelerated speed, the reinverting movement being 'controlled by stationary guide rails. The speed of the jars is again reduced as they arefcompleting this vrein'vert'in'g movement and may beagain increase'd'as the jars vapproach the discharge end of" the Aconveyor to A"bring the speed into synchro'nism with the meansfor vautomatically removing them 'from the conveyor. g c n Y Another feature of the invention relates tothe variation in the width of the spiral channel 'at different points along the conveyor. At the intake end of the conveyor thechannel isof'a width to permit the jars to advance while in an upright position,` with their axes vertical.v As the pitch of thechannel is increased, thewidth 5 Claims. (Cl. Hi8-'33) ofthe channeldsjgradu'ally reduced tojsuch fa degree that tne'angular position 'or the iarswhil'e 2 passing through the high-speed zone is'accurate 1y controlled, the jars being held in an inclined position vcorresponding to the inclination of the spiral channel. In other words, the longitudinal axis'of the jar is maintained substantially tangentrto its path of movement through the highspeed Zone while the top and bottom surfaces of the jar are substantially parallel with vthe stationary, spiral guiding rods along which said surfaces travel. The width of the channel is in like manner adapted to the angular position of the jars while the latter are being reinverted.
Further features of the invention and its precise nature will appear more fully hereinafter.
Referring to the accompanying drawings:
Fig. 1aI is a plan view of the major portion of the conveying mechanism including the intake end of the conveyor.
Fig. 11b is a like View of the remaining portion of the conveyor mechanism.
Figs. 2, 3 and 4 arefcross-sectional views at the vertical planes of the correspondingly designated section lines on Figs. la and 1b, looking in the directions of the arrows. Fig. 2 shows a jar in upright position for receiving the washing water. Fig. 3 shows the jar inverted and being sprayed with a rinsing Water. Fig. 4 shows the jar inverted after the washing and rinsingoperations.

Fig. 6 is a view similar to Fig. 5 showing the jar at an intermediate point in the reinverting zone.
The present invention relates to article-conveying and washing mechanism of the type disclosed in the patent to Hohl et al., 2,461,277, February 8, 1949, Article Conveying Mechanism, and embodies various modifications and improvements of the mechanism shown in the patent.
The screw conveyor disclosed in the present application may be combined with a mechanism such as shown in said patent for feeding the jars or other articles to the conveyor.
Referring to the accompanying drawings, `the 'screw-conveyor I0 is horizontally mounted within a frame lI I. The conveyor mechanism may be enclosed or partly enclosed by a sheet 'metal housing comprising vertical sides I2 and a top or 'cover I3 connected to the frame by hinges I4, Fig. 3.
