transverse conveyer while maintaining the pallets transversely of the latter conveyer. The construction of this gravity rollv is of little importance in the present connection, but it may beflescribed briefly as consisting of two curved downwardly extending tracks. Y

the cables beneath and vertically betweenthe outgoing cables, such lower cables serving to return the pallets to the main con veyer in a manner which will hereinafter be brackets are other sheaves'lS spaced from each other but closer together than the sheaves 7 in the upper line.

Instead of using a number of variously disposed sheaves to direct or lead such cables to the returning sheaves'S which are rotatably mounted upon the inside of the brackets 5, 'I provide a single pair of comparatively large sized sheaves 20 which are mounted at an oblique angle to the plane of the outgoing conveyer and have their upper surfaces substantially in line with the upper surfaces of the upper or outgoing sheaves, such large sheaves having their lower surfaces substantially in line with the upper surfaces of the lower lines of sheaves, and it will be noticed that such end sheaves are disposed at a substantial distance from the nearest of the sheaves in the brackets.

The cables are returned upon the lower sheaves, the brackets being provided with angle irons 12 which are mounted parallel and horizontally alined with the returning cables, such angle irons serving ,to keep the pallets in position upon'the cables and to prevent the same from'sliding oif the cables at any point in thereturning line. The returning cables are directed downwardly at a point adjacent to the main conveyor, and a gravityA roll 13 is provided toreceive the pallets and to transfer the same to thereturning main conveyer, the cables on the transverse conveyor being led over sheaves 14 at'the other side of the said conveyor.

The sheaves 14: are of large size and are Y placed vertically in order that they may be simultaneously operated by 'a single shaft 21. distance from each other as the sheaves 7 and are alined therewith.' .lt is, therefore necessary to provide means for leading the cables 22 from the nearest adjacent pair Vof sheaves in the lower line to the lower surfaces of the sheaves 12. In order to prevent any sharp bends in the cables the sheavesv 1li are'placed at a considerable distance from the end sheaves 24 in the lower hne and a single pau' lof sheaves 25 1s disposed be- Upon the inner sides of the These sheaves are spaced at the same' tween the sheaves '14 and the sheaves 24.'

By the provision of this long lead the cables work attached to the tracks, such framework also carrying rollers 16 slightly spaced 4from the lower rollers but alined there-l with. The upper andlower rollers are spaced to permit a pallet to just pass therebetween and/serve to maintain the pallet in va substantially horizontal position until the same has been shot out over the returning cables of the main conveyer. The gravity roll is at an angle adapted to give the returningpallets sullicient speed to carry them across the main conveyor and against a bumper or stop 18. Upon striking this stop the pallets drop downward upon the returning cables of the main conveyer are thus returned' to the press where they may be either removed by an operator or stacked by suitable mechanisinfor further use-ru The operation of the device will be clear from the foregoing description, but it may be advisable to briefly summarize the operation at this point. AEach pallet 17, as 1t is carried by the main conveyer, extends trans Yvcrsely of the same and on its upper surface carries a number of newly molded brick 2T. This pallet with its load is shunted to a transverse conveyor but is maintained in the salue position with .respect tothe cables of the latter, so' that :is it passes into the drying room van operator may conveniently grasp either cnd o'f the pallet and place the'.` same upon the shelves in the drying plant.

After he has placed a loaded pallet on the shelves he places an empty pallet between the angle irons in the lower part of the standards through which the cables pass, and this pallet is picked up and is carried longitudinally by the returning cables until it strikes the gravity roll which controls its passage onto the returning cables of the main conveyer.

1t has been found that by returning the cables of the transverse conveyer in the present manner, and by thus eliminating all laterally disposed sheaves to direct the Crt cables, that the life of the cables has been very materially increased, there being but slight wear on the same and nostrain except in one direction` siderable strain' and bending so long as the strain which is impressed upon the same is not reversed too far. .The present invention takes this well known fact into account, and the cables are never bent reversely nor It is, of course, well known that a cable or wire w1ll stand consharply. which is the canse of their increased life.

Other modes of applying the principle of my invention may be employed instead of he one explained, change being made as regards the mechanism herein disclosed. provided the means stated by any7 of the following;- clainis or the equivalent ot' such stated means be employed.
