Our present invention has for its object to provide a simple, strong, and durable conveyor or elevator leg intended for general use but especially7 well adapted for use in connec- 5 tion with a portable grain or other elevator.

To the above end, generally stated, the invention consists ofthe novel devices, and combinations of devices hereinafter described'and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective View of a portable 15 Grain elevator having the invention embodied t erein; and

Fig. 2 is a view in transverse sectiontaken on the line 2-2 of Fig. 1 on an enlarged scale.

The improved conveyor or elevator leg 3, as shown, is embodied 1n a portable elevator of the type commonly used for loading cars, filling bins, and the like.

Of the parts of the grain elevator illus- 25 trated, apart from the leg 3, it is only necessary to note the receiving hopper 4, supporting wheels 5, trough 6, head 7 flexible delivery spouts 8, and supporting legs 9. The trough 6 which, as shown in the drawings, 30 is in an inoperative position is: hinged to the receiving hopper 4 for movement to or from an operative position in which it rests on the roadbed to receive grain as the same is discharged from a wagon or truck.

A conveyor, not shown, is mounted in the trough 6 for delivering grain discharged therein to the receiving hopper 4. The elevator working in the leg 3 includes an endless belt l() and a plurality of longitudinally spaced flights 11 which extend transversely of said belt and are secured thereto at their longitudinal centers, see Fig. 2. This belt 10 is arranged to run over sprocket wheels, not shown, journaled in the receiving hopper 4 and the head Driving connections, operative from' an internal combustion engine or any other lsuitable source of power not shown, for the conveyor in the trough G and the elevator lO-ll are indicated as an entirety by the numeral 12.

. Referrin noiy in detail tp thefn-iifd mangeur-fi ae-theautresaselreaan'setee tangularwin cross section and comprises iifhU-ft uppeitlstetinialiiifhtion 14 and a partition lliivlicli divideidlleg into an upper l5 arg compartment 16 and a lower compartment i 17. `The leg sections 13 and 14 have on the adjacent edges ot their sides outturned flanges 18 between which the longitudinal edge portions of the partition 15 extends and 60.11;; which flanges and partition are rigidly connected by rivets 19. By reference to Fig. 2, it

will be noted that the lower or upwardly moving section of the elevator 10--11 travels in the lower compartment 17 and the upper or es return section of said elevator travels in the upper compartmentl. The flights 11 substantially transversely fill the compartments 16-17 with sutticient clearance to travel freely therein.

Grain delivered into the receiving hopper 14 is elevated in the compartment 17 by the lower or'upwardly moving iights 11 which push the grain upward on the smooth bot- 'Nea tom of said compartment and deliver the "ai,

same through the headl 7 where the same is precipitated into the flexible discharge spout 8.

The top member of the leg section 13 and the partition 15 have pressed therefrom a soa-a plurality of 11p-standing longitudinally extended reinforcing ribs or corrugations 2O and 21, respectively, that are V-shape in cross section. The corrugations 21 in addition to reinforcing the partition 15 and hence 85.33 the elevator legr performs another important function in that they a tl'ord slides or rails on the apexes of which the upper flights 11 travel during their return nun ement, see Fig. 2. It is important to note that the corrugations 21 Nte are so arranged within the compartn'lent 1G as to leave a relatively wide runway 22 therebetween for the return section of the belt 10. The height of the corrugations 2l is such that the upper fiights ll hold the respective sec- 9g@ tion of the belt l() entirely out of contact with the partition l5 so as to eliminate wear and noise. rl`he flights 11 are preferably made of wood but, ot' course, any other suitable material may be used. 1Q@

From the above description it is evident that the construction of the elevator leg 3 is such that the same is relatively light, very strong and durable.

What I claim is:

A device of the class described comprising a. casing, and a sheet metal partition dlviding the casing into upper and lower compartments and having formed therein longitudim nally extended corrugations affording rails on which the flights of an endless conveyor travel during their return movement, said rails bein laterally spaced to leave afassageway for t e belt o the conveyor, an of such 15 height as to hold said belt out of contact with the partition. c

In testimony whereof\vve aix our signatures. l
