A. F. WHITE Feb. 3, 1942.
CONVEYER Filed Feb.v 27, 1941 INVENTUR aawm Patented F eh. 3, 1942 oonvama Albert Francis White, Toronto, Ontario, Canada, 'assignor to Chain Belt Company, Milwaukee, Wis., a corporation of Wisconsin Application February 27, 19 l1, fSerialNo. 380,884 8 Claims. (01. 198-170) This invention relates to conveyers and more particularly to those having flights moving in closed conduits for .conveyinggrain and other bulk material that can be poured. The object of the present invention is to devise simple and inexpensive means for causing all the material to be completely cleared from'the flights when they reach the point of discharge.
The invention is hereinafter more fully described and is illustrated by way of example in the accompanying drawing in which Fig. 1 is a side elevation partly in section of my improved conveyer;
Fig. 2 a front elevation broken away; v
Fig. 3 a detail in sidd'elevation, on an enlarged scale, of part of the chain showing a flight con less draft mechanism operating therein. The
casing may be of any ordinary construction and its shapemay be varied. It is provided with a rising orupwardly extending leg I which will usually be rectangular in cross section in which arms Ill extend-from alternate double hinge knuckles 8 to a point adjacent the front wall I' of the leg I and each arm is provided with a hinge knuckle I2 adapted to be receivedbetween two hinge knuckles I3 on-a flight II. Apintle I4 is passed through each set of knuckles I2, I3. The
flights approximately fit the cross-section of the leg I and have openings I5 to clear the chain The-rear edge of each flight is adapted to rest of I the same, partly plished by providing suitable means movable relaon the upper end of the adjacent double hinge knuckle 8 whereby the flights are adequately supported at their front and rear edges during their passage through the leg I.
To enable the loads on the flights to be completely cleared intothe outlet6, the flights are tilted seriatim on their pivots I4. This is accomtive to the sprockets 1 and chain 8-, forming the draft'mechanism, for raising the rear edges of the flights. The preferred construction comprises a pair. of toothed wheels I6 locatedat opposite sides of the links 8. The wheels have one or-more teeth or projections I'I projecting through slots I8, in the rear wall I of the leg I, into the case the leg will have a front wall I, a rear'wall loop 4. The bottom loop is provided with an inlet 5 and the upper end of the upwardly extending leg I is provided with an outlet 6.
The draft mechanism includes a sprocketwheel v 1 located in the top loop, and an endless chain located at the lower ends of the links 8* in the path of the flights II for engaging the latter seriatim. The wheels I6 are so driven that the peripheral speed of theteethor projections I1 is greater than ,the linear speed of the flights to cause the latter to be tilted. The wheels I6 may be secured to a shaft I9 suitably journaled in the v I casing and this'shaft may be driven by sprockets and'a chin :30 or gears from the shaft 2I to which the sprockets 'I are secured.
The eye ends of the links 8 carrying the flights are provided with forwardly extending lugs 22 for limiting the swinging movement of the flights as they descend so .that each flight will be properly positioned to pick up a fresh load'as it nears the inlet 5. i 1
. It will be distinctly understood that various I modifications may be made without departing from the spirit of my invention.
rising leg I andthe lower ends of these knuckles The chain lies close to the inner or rear wall I of the upwardly extending leg I and the links are provided with forwardly extending arms lIl on which flights II are pivoted. Preferably the 5 What I claim as my invention is: 1. A conveyer comprising a casing having an upwardly extending substantially entirely enclosing leg and an outlet; draft mechanism in i said casing comprising an endless chain mounted to move longitudinally of the leg; a plurality of conveyer flights pivoted on the chain, each flight approximately fitting the cross-section of the said leg; and movable means for engaging the flights seriatim, the point of engagement of said means with said flights being actuated at a, R
greater speed than that of the draft mechanism;
v to cause the flights to betilted 'seriatim to a discharging position when the outlet is reached. 2. A conveyer comprising a casing having an upwardly extending substantially "entirely enf closing leg and an outlet; draftmechanism in said casing comprising an endless chain mounted tomove longitudinally of the leg; a plurality of conveyer flights pivoted on the chain, each flight approximately fltting the cross-section of the said leg; and rotary means including a projection for engaging the flights seriatim, the peripheral speed of the projection being greater than the linear speed of the flights to cause the latter to be tilted to a'discharging position when the outlet is reached.
