An endless screening conveyor I0 is oper able longitudinally around the frame structure I, the upper ?ight of said conveyor traveling be tween the sideboards 9, the lower ?ight of‘said conveyor passing beneath the platform 5. The endless conveyor I0 is trained around rollers II the potatoes as they are discharged therefrom and which are journaled transversely in the front, sacking said potatoes. rear, upper and lower portions of the frame struc Another important object of the invention is to provide a potato sacker of the aforementioned 10 ture I, said rollers having sprocket wheels I2 ?xed ventional potato digging machine for receiving character comprising an endless conveyor for moving the potatoes, which conveyor is adapted to be driven from the digging machine. Other objects of the invention are to provide a on their ends. ‘ The conveyor Ill includes endless sprocket chains I3 which are trained over the sprocket wheels I2. The endless chains I3 carry sweeps I4, potato sacking machine of the character described 15 said sweeps including bars I5 of wood or other suitable material which are secured transversely which will be comparatively simple in construc on said chains I3. Strips I6 of rubberizedfabric are mounted on the bars I5. Mounted on the bars I5 are spaced, longitudinally extending end be manufactured at low cost. _ All of the foregoing, and still further objects 20 less fabric belts or the like I'I. One of the rollers II is adjustably mounted, as at I8, on the lower and advantages of the invention will become ap front portion of the frame structure I for regu parent from a study ofthe following speci?cation, lating the tension of the endless conveyor I0. taken in connection with the accompanying draw As illustrated to advantage in Figure 1 of the ings wherein like characters of reference desig nate corresponding parts throughout the several 25 drawings, the shaft I9 of the forwardmost roller II projects laterally from‘the frame structure I views, and wherein: and has ?xed thereon a ‘sprocket wheel 20. The Figure 1 is a top plan view of a potato sacking sprocket wheel 20 is to be driven by an endless machine constructed in accordance with the pres sprocket chain (not shown) from the rear end of ent invention. Figure 2 is a view in side elevation of the ma 30 the usual conveyor of a conventional potato dig ging machine. Arms 2I are journaled on the chine, showing an upper portion thereof broken shaft IS. The arms 2| are to be secured to the away. tion, strong, durable, highly efficient and reliable in use, compact, light in weight and which may Figure 3 is a view in rear elevation. . potato digger for attaching the sacker thereto and for supporting the forward end of the frame Figure 4 is a detail view in perspective of one 35 structure I thereon. The shaft I9 is operable in of the endless conveyor sweeps. the lower end portion of an inclined trough 22 on Referring now to the drawings in detail, it will the upper portion of the forward end of the frame be seen that the embodiment of the invention structure I. The endless conveyor I0 is operable which has been illustrated comprises an elon in the trough 22. ‘ gated frame structure of suitable dimensions and It is thought that the operation of the machine 40 material which is designated generally by refer ence numeral I. The rear end of the frame struc ture I is adjustably supported on a caster wheel 2. Mounted in the upper portion of the frame structure I is a hopper 3 including an inclined grill or screen 4 which functions as a screening will be readily apparent from a consideration of the foregoing. Brie?y, the potatoes from the dig ging machine are deposited in the trough 22. The endless conveyor I0 moves the potatoes upward ly in the trough 22 over the hopper 3. When the potatoes enter between‘ the sideboards 9, said discharge chute. \A platform 5 is mounted in the potatoes drop through the openings or spaces lower portion of the frame structure I below the de?ned by the members I4 and ll of the end hopper 3. Brackets 6 are mounted on the up less conveyor Ill into theihopper 3. From the rights ‘I of the frame structure I. Planks 8 are 50 hopper 3 the potatoes gravitate into a bag which mounted on the brackets 6, said planks constitut rests on one of the running boards and is held ing running boards in the form of lateral exten in position beneath the discharge mouth of said sions of the platform 5 to accommodate the sacks ‘hopper by a suitable bag holder H as shown. and necessary workmen. It is’believed that the many advantages of a Upstanding sideboards 9 are mounted longi 55 potato sacker constructed in accordance with the 2,407,017 3 4 present invention will be readily understood, and although a preferred embodiment of the machine is as illustrated and described, it is to be under stood that changes in the details of construc tion and in the combination and arrangement of parts may be resorted to which will fall within wardly at the front of the frame, a ?ight moving rearwardly and horizontally over the hopper, a ?ight moving downwardly at the rear of the frame, and a ?ight moving forwardly and hori zontally at the bottom of the frame in spaced relation to and below the hopper, means to the scope of the invention as claimed. hitch the front end of the frame to the rear What is claimed is: of the potato digging and elevating machine to A unitary potato screening and sacking trailer be drawn‘ and supported by the latter, means at attachment for a potato digging and elevating 10 the front of the frame to facilitate driving the machine, comprising an elongated rigid frame, conveyor, running boards along the sides of the wheeled supporting means for the rear end of the . iframe near the bottom of the latter and at 0p frame, a hopper mounted in the upper portion of said frame and including an intermediate portion in the form of a laterally inclined screen-j ing discharge chute, an endless, screening con-_ veyor carried by the frame and guided for travel to provide a ?ight moving upwardly and rear posite sides of the last named ?ight to accom modate sacks and workmen, and means to sup port asack in position on one of the running , " boards to receive chute. potatoes from the discharge " HERMAN L.
