UNITED STATES PATENT OFFICE,

GUSTAV ANDERSON, OF ELLS, MINNESOTA.

GRAIN MEASURER AND BAGGER.

SPECIFICATION forming part of Letters Patent No. 468,091, dated February 2, 1892.

Application filed March 23, 1891. Serial No. 385,954. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV ANDERSON, a citizen of the United States, residing at ells, in the county of Faribault and State of Minnesota, have in vented certain new and useful Improvements in Grain Measurers and Baggers;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an eficient grain ineasurer and bagger. To this end I employ a case divided bya vertical partition into two compartments,having above the same a common feed-throat in comm unication with the elevator-hood or other source of supply, and having below the compartments a common discharge-waist provided with divergent discharge chutes or legs to which the bags are attached. The compart* ments are provided with pivoted bottomsconstituting their discharge-valves, and in the throat is placed a cut-off and shunt valve for controlling the inlet of the grain to the compartments. In the discharge-waist is placed another cutoff and shunt valve to direct the grain through one of the other chutes at will. The inlet and discharge valves are connected to a common shaft, which is controlled from a forcedfeed located in the feed-throat, the connections being such that whenever one coinpartment has become filled and the grain accumulates in the feed-throat the resistance thus afforded to the forced feed will trip the valve-operatingmechanism, opening the dis charge from the filled compartment, closing the discharge-valve of the empty compartment, and shifting the shunt or cut-oft valve to its opposite position, so as to exclude the grain from the filled compartment and direct the same to the empty compartment. The shunt-valve in the waist is controlled by hand, so as to direct the discharge into one bag or the other, as required.

In the accompanying drawings, wherein like letters refer to like parts throughout, Fig ure 1 is a side elevation of the invention. Fig. 2 is a vertical section of the same. Fig. 3 is an end view of a part of the case, some portions being broken away; and Figs. 4: and 5 are details showing the clutching and tripping mechanism for operating the valves.

Ais the elevator-hood. Bis the feed-throat. C C are the measuringcompartrnents divided by the partition 0. I) is the dischargewaist, and E E are the discharge chutes or legs. The various parts above specified are preferably constructed so as to be continuous within a common case, the central part of which is enlarged to give space for the two compartments.

F is the cut-off or shunt valve in the feedthroat, and is formed of a fiat plate rigidly secured to the free end of a pendulum or rocking arm F, suspended from a point above the partition 0'. As shown, the arm F is a crank-arm on a transverse shaft G, provided on the exterior of the case with bell-cranks g and g. This construction of the shunt or cut-off valve causes it to operate with an upward and outward sweep from the head of the partition 0. gins to move an opening is formed into the empty compartment and the upward stroke on the filled compartment acts like a striker, leveling the grain and throwing the excess over into the empty compartment.

II II are the pivoted bottoms or dischargevalves, and h 72, are connections from the free ends of the same to the crank-arms g g on the shaft G.

K is a packer-driving crank-shaft at the head of a feed-throat, at least one end of which is mounted in sliding bearings, so that the shaft is free to rise or fall therein.

ll is the pivoted packer supported from the pivoted bail L and driven from the crankshaft K by the connecting-rod K.

v M is the valve-driving shaft, alsolocated in the head of the feed-throat, adjacent to but lower than the packer-shaft K.

N is a cam-crank, loosely mounted on the shaft M, having a pair of cam-surfaces on its periphery, with their notches or shoulders at diametrically-opposite points.

N is a connecting-rod from the cam-crank N to one of the crank-arms g g. The cam N is provided with an extended hub 71.. On this hub is loosely mounted a trip-leverP, having Hence from the time it be IOO - lever is under tension from a spring P, which tends to throw the arm P outwardly radially to its limit.

On the shaft M, adjacentto the cam N, is a clutch-arm Q, rigid with the shaft, having fingers q projecting toward the face of the cam-disk.

On the packer-driving shaft K is a hookdetent K which projects from the shaftinto position to engage with the cam-surfaces on the disk. The engaging-lip of this detent is of abreadth to strike not only the shoulder of the cam, but also the adjacent face of the trip-lever P. Normally this detent engages the cam-shoulder and trip-lever and holds the arm P inward to its limit against its retracting-spring P". in the feed-throat, so as to form a resistance to. the pivoted packer L, the shaft K will be lifted thereby and the detent K" lifted out of engagement with the cam-shoulder, and the trip-lever will thenbe thrown outward, bringing the pawl P into the path of the projecting fingers q of the clutch-arm Q. The disk will then be rotated with the shaft for a halfrevolution, operating the valves. The accumulated grain in the feed-throat having passed to the empty compartment, the packermitting the detent to engage with the shoulder of the other cam, holding the trip-lever and the valves in their normal position, as at the start. the trip-lever is again permitted to escape, the disk is revolved for another half-revolution, and the valves are operated in a reverse direction.

R is the shunt-valve in the discharge-waist, depending from the shaft R, which projects through the face of the case and is provided with a crank-arm B". This shunt-valve operates similar to the cutoff valve F byan upward sweep from the dividing angle between the dis charge-legs. The discharge-legs are provided margin of the mouth of the bag being drawn When the grain accumulates around these ledges and the lap taken up at one corner by a spring-clamp T.

'V represents a part of the bag in position.

As shown, the crank-arms g and g on the shaft G are connected by a segment G, to which is attached onnecting-rod W, connect-' ed at its other end to a rock-shaft W, which may be used to operate a registering device.
