"GRAIN WEIGHING, REGISTERING, AND BAGGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 377,163, dated January 31, 1888.

Application filed September 8, 1887. Serial No. 249,168. (No model.)

To all whom it may concern.-

Be it known that 1, GEORGE R. KENDRIGK,

of Bryant, in the county of Jay and State of Indiana, have invented a new and Improved Grain ll'leasuring, Registering, and Bagging Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine which takes the grain from the separator of the thrashing-machine, measures and registers it, and finally delivers it in measured quantities to bags.

The invention consists in the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improve- Fig. 2 is a side elevation of the same, showing the elevator, parts of the frame, and one hopper in section. Fig. 8 is a sectional elevation of myimprovement on the line as x of Fig. 4, looking toward the front. Fig. 4 is a plan view of the same with the elevator-spout in section. Fig. 5 is an enlarged face view of part of the shifting mechanism for the grain-measuring recepta cle. Fig. 6 is a face view of the cam of the shift ing mechanism. Fig. 7 isasectional face view of the same, showing the levers in a different position. Fig. 8 is a plan view of the same. Fig. 9is a sectional plan view of the lower part of my improvement on the line y y of Fig. 1; and Figs. 10 and 11 are side elevations of the grain-measuring receptacle, showing its hinged bottom open.

In a suitably-constructed frame, A, is held an elevator, B, of any approved construction, and connected at its lower end with the separator of the thrashing-machine, so that the grain from the thrashing-machine passes into said elevator, and is raised by the buckets B into a spout, B projecting from the upper end of the elevator-frame. The upper shaft, 13, of the elevator carries on one outer end a sprocket,'B, over which passes a sprocketchain, B", also passing over a sprocket-wheel,

B, secured to a shaft, B mounted to rotatein a frame, B fulcrumed on the shaft B of the elevator. On the shaft 13 is also secured a pinion, C, adapted to mesh into a gear-wheel, O, which has its teeth depressed in one part of .rotation the teeth of the pinion G turn out of mesh at this point 0 as illustrated in Fig. 1.

The gear-wheel Ois secured on the shaft 0 mounted to rotate in suitable bearings held on the main frame A. From the face of the gear-wheel 0 projects alug, 0, adapted to engage at each revolution of said wheel with an arm, D, having an offset, D, on which rests the lower end of an arm, D", secured to the swinging frame B The arm D is fastened on the shaft E, mounted transversely on the main frame A and carrying a spring, E, which is fastened by one end to said shaft E and by its other end to the main frame A, so that when said shaft is turned the spring is wound up, and when said shaft is released the spring causes it to turn back to its former position. On the shaft E is also secured an arm, E", connected by a link, E, with an arm, Ff, secured on the shaft mounted transversely on the lower end of the spout B of the elevator, said shaft carrying a door, E, which, in connection with a door, E, secured on the shaft E, forms the bottom for the spout B \Vhen the two doors and E swing toward each other until their outer ends meet, the hopper-bottom is closed and the grain discharged by the elevator accumulates in the spout B The outerend of the arm E is held in a downward position by a catch, F, secured to a shaft, F, mounted to rotatein the frame A and carrying an arm, F which extends over one end of the weighing-beam G, hung in suitable bearings on an arm,G, fastened on the shaft H, mounted vertically in suitable bearings on the main frame A. The outer end of the weighing-beam G- is connected with a spring-scale, I, of any approved construction,and supported by the arms I, secured to said shaft H. The inner ends of the weighingbeam G support the grain-measuring receptacle J, of suitable size and construction, and connected at its lower end by a link, 1 with the leverarm I, secured to the shaft H, so as to prevent said grain-measuring receptacle from tipping over. The bottom of the grain-measuring receptacle J consists of two hinged doors, J and J, pivotally connected with each other by the arms .1, so that said doors open and close simultancously. The door J is pivotally connected its rim, so that when said gear-wheel makes a by the link JP with a crankarm, J secured to one end of a shaft, J, mounted to rotate in bearings formed in the grain-measuring receptacle J and passing through the center of the same. On the other outer end of the shaft J is secured a tripping device, K, which consist-s, principally, of a lever-arm, K, fastened to said shaft J and provided with a segmental offset, K against which operates the upper end of the arm K pivoted on said lever K. The latter and the arm K are operated on alternately by the studs or lugs K" and K secured to the side posts, A, of the main frame A, as shown in Figs. 3 and 9. The upper end of the lever K is pointed at K, and is adapted to engage a notch formed on the arm K, fulcrumed on the grain-measuring receptacle J, and held in any desired position by a spring, K A stop, K secured to the grain-measuring receptacle, limits the downward motion of the arm K and holds the same in nearly a horizontal position.

The open upper end of the grainmeasuring receptacle is always under thelower end of the spout B so that when the doors E and E are opened the grain passing to the elevator B is discharged into the grain-measuring receptacle J, The graiirmeasuring receptacle swings with the vertical shaft H, so as to discharge alternately into the hoppers L, placed alongside of each other, as shown in Figs. 3 and 9, and each provided at its lower end with hooks L, on which the bags to be filled are hung. The swinging motion of the shaft H is imparted by the device presently to be described and receiving its motion from the gear-wheel C.

On the upper end of the shaft H is secured a bevel gear-wheel, N, meshing into a bevel gear-wheel, N, secured on a horizontal shaft, N mounted in suitable bearings fastened on top of the main frame A. On the shaft N is held the grain-receptacle-shifting mechanism O, provided with a disk, 0, held on said shaft N and having notches O at opposite points in its rim, said disk also being provided on its face with a cross-piece, Oiwhich connects with the disk 0', having a hub placed directly on the shaft N and secured to the same by a setscrew or other means. On one of the notches O" of the disk 0 operates the pawl Q, held in contact with the rim of the disk Obya spring, Q, and said pawl Q is pivoted on a lever, N fulcrumed loosely on the ,shaft N and connected by a link, N, with the gear-wheel C. On the other notch O of the disk 0 operates a pawl, Q", pivoted on a lever, Qj, fulcrumed loosely on the shaft N and connected by the link Q" with the gear-wheel O 'on the same crankpin which connects thelink N" with said gear-wheel G. The levers Nand Qfare placed alongsideofeach other and extend between the disks 0 and O", passing on opposite sides of the cross-piece 0". On the fulcrum of the pawl Q is also held a pawl, R, connected at its .outer end by a spring, R, with the outer end of said pawl Q so that the latter is pressed in contact with the rim of the disk 0, and the pawl R is pressed, with its hook-R in contact ,with the notched rim of the disk Riloosely mounted on the shaft N The hooked end It of the pawl It can be prevented from engaging the notched rim of the disk R by a lever, S, loosely fulcrumed on the shaft N" and provided with the segmental offset S, extending over part of the rim of the notched disk it On the outer end of the lever S is held a hand-lever, S", adapted to engage with its inner end one of the notches T, formed on the segmental arm T, secured to the top of the main frame A. The return movement of the notched disk It is prevented by a spring, R, engaging with its free end the rim of the said notched disk R On an extension, T of the segmental arm T are pivoted the pawls P and P, each provided on its inner edge with a projection on which operates a cam, It, secured to the notched disk R. The pawls P I are connected by a spring which holds them properly for action by the cam l. The cam R is so arranged that it presses the pawls P and P outward alternately,so that the respective pawl Q or Q is disengaged from its respective notch O in the disk 0, as shown in Fig. 5. Thus when the gear-wheel O rotates it moves the levers N and Q outward toward each other, and the respective pawl Q or Q which engages itsnotch in the disk 0 imparts a rotary motion to thelatter,whereby the shaft N is turned, thus imparting by the gear-wheels N and N a turning motion to the shaft H, which carries the grain-measuring receptacle J. On the return-stroke of the levers N and Q the respective one which accomplished the shifting of the disk 0 moves the latter backward by engaging with the cross-piece 0, so that the shaft N is turned in an opposite direction and the grainmeasuring receptacleJ agai n assumes its former normal position in the center of the machine between the two hoppers L and directly under the lower end of the spout B;

The pawl P or P which disengages, respectively,either the pawl Q or Qflthus changing the shifting of the grain-measuring receptacle to the right or left, is changed by the cam R", which isgoverned by theposition ofthe notched disk Rflturned on the shaft N by the pawl R; but the latter engages only part of the rim of the notched disk R if desired by the operator, during its stroke, on accountof the segmental arm S,which coverssome of the notches in the said disk,and is placed,according to the operation to be performed, in such relative position to the disk, by changing its hand-lever S into a corresponding notch in the segmental notch T, that the hooked end It of the pawl R travels through part of its stroke on the arm S and through the remainder of its spective pawl Q or Q is'disengaged from the notch O of the disk 0. Thus the operator can cause the grain-receptacle J to move to the left or. right either by one revolution of the gear -wheel 0, or by two, three, or four revolutions of said wheel, according to the amount of grain to'be emptied into one hopper L at a time. i

The outer end of the shaft C carrying the gear-wheel O, is connected with a registering mechanism shown in dotted lines in Fig. 3, and being of any approved construction, so that each revolution of said shaft is indicated on said mechanism.

The operation is as follows: When the machine is in the position illustrated in Figs. 1, 2, 3, and 4, then the doors J and J of the grain-measuring receptacleJ are closed, and the doors E and E on the bottom of the spout B are opened, so that the grain elevated by the elevator Bis discharged into said spoutB", and passes over the doors E and E into the grain-measuring receptacle J, in which it accumulates until a certain weight to which the scaleI is set is reached. The grain-meas uring receptacle J then swings downward and the outer end ofits scale-beam G presses against the lever F", which swings the catch F away from the outer end of the arm E, so that the latteris released, and the compressedspring E, exertingits power, turns the shaft E,whereby the doors E 'and E are swung upward, thus closing the'lower end of the spout B". The graint'rom the elevator, instead of passing to the receptacle J, nowaccumulates in said spout B. The shaft E in turn, as above described, causes the arm D to swing with it,

so that the lower end of the arm D loses its support, the shoulder D, whereby the frame B to which said arm D is secured, swings'downward, and the pinion O is thus thrown into mesh with the gear wheel G. The movement of the elevator B imparts a rotary motion to said pinion O, and as the latter is now in mesh with the gear-wheel C said gear-wheel is also rotated, whereby the linksm and Q se the levers N and Q" to swing toward the rear, and the respective pawl Q or Q which engages with the disk 0 turns the latter in one direction, so that the shaft N is rotated, and by the bevel gear-wheelsN and N imparts a turning motion to the vertical shaft H, which, as it carries the grain-Incas uringreceptaclc J, swings the latter to one side over one of the hoppers L. The grain measuring receptacle, on passing over one of the hoppers L, causes the arms K and K to move against the respective lugs K and K,

whereby the upper end, K, of the lever K is disengaged from the notch of the spring-arm K and at the same time the transverse shaft J is turned, and, by its crank-arm J and the link J, swings the door J downward, so that the other door, J, is moved in the same direction by the connecting-links J The grain held in the grain -measuring receptacle thus passes out into the respective hopper L and into the bag held on the hooks L 011 said hopper. Theamount of grain passed into the bag is known by the scale I, and the registering device connected with the shaft 0 on which the gear wheel 0 is located, registers said amount. As .soon as the gear -wheel 0 has made a half-revolution, then the respective lever h or Q imparts a return movement to the disk 0 by engaging the cross-bar 0 so that the shafts N and H are turned in an'opposite direction, and the grain receptacle J commences to swing toward its former position in the center of the machine. On this return movement of the grain-measuring receptacle the arin K, which by its own gravity has as sumed the position shown in Fig. 10, comes in contact with the respective lug K or K and thereby causes the lever K to swing into a vertical position again, so as to engage the notch in the spring-arm K, and at the same time impart a swinging motion to the crank arm J by its shaft J, so that the doors J and J 2 again close the bottom of the grain-measuring receptacle J. The doors are held in a closed and locked position by the spring-arm K engaging the lever K. When the gearwheel C has nearly accomplished its last halfrevolution, its stud G engages the upper end of the arm D, which is swung into its former position and lifts, by means of its shoulder D, the arm D so that the frame B is swung upward and the pinion O is disengaged from the gearwheel 0, which has now made a halfrevolution. The swinging motion imparted to the arm D causes the shaft E to turn, so that the spring E is again compressed and the arm D is swung downward and is locked in position by the catch F. The arm F", connected with said catch, was free to return to its former position as soon as the grain-measuring reeeptacle had emptied and its frame had swung upward again to its former position by the action of the spring in the scale I. 'lhis'downwardswinging motion of the arm D causes the open ing of the doors Ff and E, so that the grain accu mulated in the spout B is again discharged into the measuringreceptacle J, and the above operation is repeated.

lfthe operator desires to discharge the grain from the grain-measuring receptacle J alternately into the two hoppers L, he places the levers S in such a position that its segmental arm S permits the pawl R to impart to the disk R a half revolution, so that the cam R of said disk It shifts the pawls P and P alternately, thus throwing the pawls Q and Q alternately into and out of contact with their respective notches O in the disk 0, whereby the shafts N and H are turned alternately in opposite directions at each revolution of the gear-wheel C.

If the operator desires to discharge the grainmeasuriug receptacle J successively two or three times into one hopper L before changing it to the other hopper,theu he places the lever S in such a position that the pawl R travels the greater part of its stroke on the segmental arm S and turns the disk R onlya short distance, so that it requires two or more revolutions of the gear-wheel C before the pawl R imparts a full half-revolution to the said disk R which does not change the posi tions of the pawls P I? or the pawls Q Q respeetively, by means of the cam R until half the revolution has been accomplished. I

It will be seen that while one bag is being filled at one of the hoppers L the operator can remove the filled bag from the other hopper and put an empty bag in its place.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
