Anoth er object of my invention is to provide gilides associated',with the lehr or,re-ceidving conveyor adapted to guide the bottles an to support them as they are dep6sited. 65 Such a,.provision is of particular moment in the transferring of @anels which are usually comparativel y i@arrow, and if deposited on,a conveyor which may be uiic@ven or while the, bottles retain any swinging movement which 70 may have, been im@arted to. them during transfer are apt to fall and to not only knock over other bottl6s already d6posited, but to interfere with the deposit bf future bottles on the lehr in sa6h a. manner as to cause break- 75 age both of themselves and of the bottles later depo ited.

In the annealing of "panels" it is usuitlly 25 desirable that thp, bottle be placed on the inovin(, lehr conveyor in . a position in which'the major axis of'its bottom is parallel to the line of movement of -the conveyor, ,is such a position reduces the chances of itbein,(,y 30 upsetbythepullontheconveyor.
