At such first station E it is desirable to divide the advancing column so as to divert a portion laterally, transferring such portion to iilling machine B according to its capacity, and the balance along the main sectional trackway 5a. I therefore provide a lateral conveyer-provided traokway 'i leading from station E to the illing machine B, along which trackway some of the bottles of the main column. are carried, the others proceeding straight along trackway 5a.

In the same manner other bottles of the main series pass beyond station E by trackway conveyer 5a to the second switching station F, and by lateral trackway 8 to lling machine C, the remaining bottles then passing along trackway conveyer 5b directly or by lateral trackway 9 to the final lling machine D.

The construction of the several conveyers is of any well known type to provide progressive movement on a common level, of closely adjacent unit supporting and carrying slats I0.

The conveyers are driven by suitable actuating mechanism at desired speeds for movement of the units, and the speeds may be regulated to accommodate the receiving capacity of the several iilling machines B, C, and D.

Thus the speed of conveyer section or'trackway 5 is the same or slightly slower than that of the preliminary conveyer leading to it from the washer A. The next section Ea is preferably of reduced speed, as is also the final section 5b and the speeds of lateral conveyers l', 8, and 9 are conformably regulated to the receiving capacity of the filling machines. Such details and adjustments will be understood as within the province of the builder or designing engineer, dependent upon the operating conditions of the installation or other controlling factors.

At each station E and F, or wherever a lateral conveyer leads 0E between the terminals of the consecutively spaced sections of a main conveyer, I provide a comparatively thin at supporting bridge section I2, forming a portion of a covering plate I3.

Such plate as in Fig. 6 is provided with clearance openings I4 for the adjacent terminal portions of the main conveyer sections 5 and 5a and 5b, and with a middle clearance portion i5 for the chains and slats of lateral conveyers l and 8.

The plate I3 as thus made is adapted to be laid across the gap portions at station E and F and is preferably on a level slightly below that of the supporting slats ID, providing an ample supporting platform for the straight or lateral movement of the units.

By such construction, assuming all the conveyer sections to be loaded, as the bottle units are advanced, say along conveyer trackway 5, they will ride over the bridge section I2 onto the lateral conveyer 'I, by which they will be conveyed to machine B. Assuming conveyer l to have been loaded to its delivering capacity, or ternporarily interrupted, the progressing series of units will be pushed continuously along over the lateral conveyer and the opposite bridge section I2 and be conveyed by section 5a to lateral conveyer 8 under the same conditions. It will be understood that the receiving capacity of machines B and C combined is less than the feeding capacity from the washer, and that all bottles not distributed laterally will thus pass onwardly through the nalconveyer trackway 5b and 9 to the remaining machine D.

Each lateral conveyer 'I and 8, preferably travelling at a slower speed than either of the main sections 5 or 5a will of course only receive and carry 01T such maximumV of bottles delivered thereto as limited by the capacity of machines B and C. Each last bottle passing onto the lateral conveyer will thus leave an open gap for straight line progress of the remaining surplus of the main column.

It will also be understood in case of, for instance, machine D being temporarily inoperative, that the entrance to conveyer section 5b may be blocked off in any suitable manner, whereupon units arriving at the station junction F will all be carried to machine C. Also, that if either machine B or C is temporarily inoperative, entrance to either conveyer 'I or 8 may be closed in the same manner with resulting longitudinal progress along the main section or sections.

The several trackways are dened by the travelling base slat members I0 and between the guiding sides II, II, of suitable construction to maintain the bottles erect, with easy clearance in their passage. At corner portions such sides may be conformably rounded to provide for easy lateral travel of the units as delivered from one line of direction to another, as is commonly practiced in similar conveying mechanism. Also at station E and F the approaching or inlet end of lateral conveyers 'i' and 3 is receivably widened by sloping or rounding the inner guiding side I Ia, providing for easy lateral movement of the units, as deiiected thereinto by cooperation of the associated conveyer elements, and as controlled by the preceding units.

What I claim is:

In combination with a plurality of spaced apart sections of alongitudinal conveyer track- Way on a common horizontal plane, a lateral conveyer on the same plane extending transversely between their terminal in receiving position relation to one of said trackways, said conveyer' and trackways being of the ilexibly connected supporting flight type.
