If it is de sired to transport the material to another posi tion from the position where itvis picked up, 'a‘ bucket structure of the aforementioned char namely, near the roller I0, then‘ the conveyer acter to be used in conjunction with conveying mechanism which is simple in construction, prac 40 systemis so extended as to reach the designated tical in its operation, and of such simple struc Y The structure is, preferably, provided with a ture that it will lend itself to economical quantity base I‘! and side plates (not illustrated) in order production. ‘ to con?ne the material 26 within a suitable Other objects, features, and advantages, in herent in my invention will become apparent 45 hopper-like structure, the belting 1 as will be seen is mounted in an endless form over the from'an examination of the accompanying draw guide pulleys of which there may be a greater ing and the ensuing description wherein like nu number than those shown, namely, 9, l0 and H. merals are used to designate like parts and in To the base structure I‘! the anchoring element which; ‘cycle of operation. Another object of my invention is to provide point 50 . . , , . r or portion [3 is secured in any manner, not actu ally indicated on the drawing. This serves the purpose of securing one end of the element I4. bucket structure. The other end of the element I4 may be secured Fig. 2 is a top view of Figure 1. Fig. 3 is an enlarged top view showing the 55 at the point I6 either to the base I‘! or to a plat Fig. 1 is a schematic arrangement showing a continuous conveyer system using my particular , 2,405,378 3 4 form I2 when such a platform is used for pur poses heretofore described. The structure of the bucket is comprised of two ?lled with material picked up thereby. plates 2| which have ?ared lip portions 22 and are secured to the body portion generally desig less conveyer means mounted on a series of pul nated 20 which is shaped as shown in order to permit travel over a pulley more conveniently, and in order to permit equalized action when engaging the wiping member M. The wiping member I4 is made of ?exible material such as textile or leather belting, or it may be made of an elastic material thus insuring better seal-m ing contact with the inverted buckets when they are in intimate contacting relationship with it. The rollers 23 are, preferably, secured to‘the ends of the bucket 21 by means of reduced ends _ during that portion of the cycle when the said bucket elements are in inverted position and 3. In a device of the character described, end leys providing a circuitous path therefor, a mul tiplicity of bucket elements secured to the said endless conveyor means, ?exible wiper means se cured below the lower portion of the said endless conveyer means, the said bucket elements pro vided with outwardly ?ared edges at the open end thereof adapted to straddle the said ?exible wiper means during that portion of the cycle when .the said bucket elements are in inverted position and ?lled with material picked up there by.‘ 4. Ina device of the character described, a 24 permitting free rotation when brought into wiper element secured to a housing and mount contact with the wiper I4. It is to be noticed ed in parallel relationship to bucket means trav that the rollers 23 have their body surface raised slightly above the edges of the bucket body 25 20 eling in a de?ned orbit, the said bucket means Comprising, body means substantially semi-cylin so as to permit a free contact with the wiper member 14 eliminating as much friction as pos sible, whereas the opposite edges of the wiper member I4 are closely con?ned within the lip structure 22 on either end of the bucket thus assuring a picking up of the: material .26 and maintaining the contents within the bucket while it is in the inverted position. ' The belting member ‘I may be, or preferably. should be counter-bored as at IS in orderto re ceive the rivet head [8 and thus provide a very secure arrangement which will at the same time permit the bucket to equalize itself in any direc tion that may be needed when it is actually pick ing up the material and when it is in contact with the wiping member thus furnishing a ?ex ible and most desirable smoothness of operation.
