SPECIFICATION forming part of Letters Patent No. 619,423, dated February 14, 1899.
Application filed April 22, 1898. Serial No. 678,4:95. (N model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM G. KRUSE, a citizen of the United States,residing at Buifalo Center, in the county of Winnebago and State of Iowa, have invented a new and useful Stacker, of which the following is a specifica= tion.
My invention relates to stackers, and has for its object to provide a simple, compact, and efficient construction of stacking mechanism adapted to be applied to and used with facility in connection with separating or threshing machines of the ordinary or any preferred construction, to provide simple means for automatically reversing the motion of the turn-table and for varying the extent of swinging movement thereof, and also to provide eificient means for supporting and bracing the carrier-frame, for supporting the adjusting devices of said frame, and for guiding the lower end of and communicating motion to the carrier-apron.
Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings, Figure 1 is a side view of a stacker constructed in accordance with my invention, the contiguous portion of the frame of a separator or thresher being indicated to illustrate the connection therewith. Fig. 2 is a plan view of the carrier-frame supporting and operating devices. Fig. 3 is a longitudinal section of the same, taken in the plane of the axis of the turn-table. Fig. 4 is a transverse section taken in the plane of the driving-shaft. Fig. 5 is a transverse section taken parallel with and contiguous to the plane of the clutch-shaft.
Similar numerals of reference indicate corresponding parts in all the figures of the drawings.
Supported by a suitable framework, consisting, in the construction illustrated, of side sills 1 and front and rear cross-bars 2 and 3, the former being in duplicate, is an annular bearing-seat 4, at the inner periphery of which is a depending flange 5, and mounted upon this bearing-seat is an annular turn-table 6, having an upstanding rim 7, forming a sprocketchain bearing.
Mounted in transversely-alined bearings in the supporting-frame, preferably contiguous to the front ends of the sills 1, is a drivingshaft 8, having a terminal sprocket-Wheel 9, connected bya chain with a sprocket-wheel 11 on a clutch-shaft 12, which is mounted in suitable transversely-alined bearings in a bracket 13, supported by the rear cross-bar 3. Said bearing-bracket is also provided with a central vertical bearing 14: for the spindle 15 of a reversible driving-gear 16, preferably of the beveled type, and permanently mesh ing with the driving-gear 16 are pinions 17 and 18, which are loosely mounted upon the clutch shaft 12. Interposed between the loose pinions 17 and 18 is an axially-movable clutch member 19, mounted upon the shaft 12 and provided with terminal clutch-faces to interlock, respectively, with the clutch-faces 20 and 21, formed, respectively, on the hubs of the pinions 17 and 18, according to the position of the clutch member 19. The reversible gear 16 carries a sprocket-pinion 22, traversed by a chain 23, which finds a bearing upon the rim 7 and is preferably terminally attached to the turn-table at convenient points, such as at the attached lower extremities of guide-standards 24, which rise from the turntable.
The clutch member 19 is provided with an annular groove or channel 25, with which is engaged a band or yoke 26, carried by a pivotal shifting lever 27, the fulcrum 28 of which consists of abolt on the cross-bar 3. The free end of this shifting lever forms a trip-arm 29, arranged contiguous to the plane of the under surface of the turn-table, and carried by the turn-table is a plurality of depending trippins 30 for alternate engagement with the trip-arm to throw the shifting lever from one position to another and thus reverse the position of the clutch member 19, whereby with a continuously-operating shaft 12 operating in a uniform direction the gear 16 may be reversed at intervals to communicate motion in opposite directions to the turn-table. In order that the shifting lever may be yieldingly held in either of its adjusted positions and thrown fully to the extremity of its stroke at each contact of the trip-pin therewith, I employ a swinging guide-pin 31, fulcrumed, as at 32, and carrying an actuating-spring 33,
which bears terminally against a pivotal guide-ear 34 near the extremity of the triparm, said car being adapted to swing to accommodate the relative positionsof the guidepin and shifting lever. When the trip-arm is engaged by one of the trip-pins depending from the turn-table, the shifting lever is swung toward the opposite limit of its movement until said lever and the guide-pin are carried beyond a position of alinement, after which the tension of the actuatin g-sprin g continues the motion of the shifting lever and carries it positively to the limit of its stroke, thereby insuring the positive engagement of one of the clutch-faces of the member 19 with the clutch-face of the contiguous loose pinion.
Carried by the turn-table is a frame consisting in the construction illustrated of approximately parallel bars 35 and a cross-bar 36, and from the extremities of the latter rise bearing-brackets 37, having axially-elongated bearings 38, which constitute axially-alined journals, upon which are mounted bearingforks 39 at the lower end of the carrier-frame 40, said bearing-forks being formed at the lower extremities of plates 4l,whieh are suitably secured to the sides of the carrier-frame. The width of the carrier-frame is equal approximately to the interval between the guiding uprights or standards 24, whereby said frame is braced against lateral vibration in all positions of the turn-table by which it is supported, and said guiding uprights or standards are extended to form approximately horizontal rearwardly-convergent arms 24, which are terminally pivoted at the intersection of the brace-arms 42,which extend in forwardlyconvergent directions from a contiguous fixed portion of the separator or other supportingframe, the pivot 43 for the extremities of the upright or standard arms 24 being vertically alined with the axis of the turn-table.
The uprights or standards,with their extensions or arms, constitute, with the turn-table, a swinging frame by which the carrier-frame is supported and guided in vertical swinging movement, and this swinging frame also forms a support for the various bracing and operating devices which may be used in connection with the carrier frame and apron. For instance, in the construction illustrated the carrier-frame is of the sectional type, having a main or body portion and an auxiliary or folding section 40 joined at their contiguous extremities to form when in operation a continuous frame and adapted to fold about hinge-pins 44. Attached to these hinge-pins are pulleys 45, traversed by operating-cables 46, (only one pulley 45 and one cable 46 being with chain-wheels 48, traversed by short chains 49, (only one chain-wheel 48 and one chain 49 being shown,) which are let into and complete the endless cable 46 to traverse the chain-wheels 4S. Said spindle 47 is also provided with a crank 50 or other operating device, whereby the ehain-wheels may be turned to operate the cable 46, and thereby either fold or extend the auxiliary section 40 of the carrier-frame. Also I employ bracing or supporting cables 51, only one of which is shown, but each of which is of double or continuous construction,with its extremities permanently attached to one side of the carrier-frame, as to the main and auxiliary sections thereof, and which at its looped or intermediate point traverses a movable pulley 52, mounted in a yoke 53, which is connected by a cable 54 or its equivalent with a drum or Windlass 55. The sides of the bracing or supporting cable 5ltraverse direction-pulleys 56, mounted upon the standards or uprights 24 near their upper ends, and the drum or Windlass 55 is mounted upon said standards or uprights near their lower ends or contiguous to the plane of the turn-table. Obviously by means of the Windlass 55 the bracing .or supporting cable 51 may be adjusted to swing the carrier-frame in a vertical plane in order that its upper or discharge end may occupy the desired position.
The carrier-apron 57, which I prefer to employ in connection with the above-described apparatus, is of double or sectional construction, the same comprising duplicate parallel endless members 57 57 each having side straps 58, connected by slats 0f the ordinary or any preferred construction, said straps being arranged to traverse pulleys 59, carried by a common apron-driving shaft 60, which is mounted in the bearings 38, abovedescribed. Thus one of the carrier-pulleys 59 is arranged contiguous to each end of the shaft 60, while the inner pulleys 5.) are arranged adjacent to the center of said shaft, and between the planes thereof is arranged a sprocket-pulley 61, traversed by a chain 62,
extending from a chain-wheel 63, of which the spindle 64 is mounted in suitable bearings upon the approximately parallel bars 35. Said sprocket-wheel spindle 64 also carries a bevel-gear 65, meshing with a double bevelgear 66, mounted concentric with the axis of the turn-table and in turn meshing with a driving-gear 67 on the driving-shaft 8.
An important advantage of the above-described construction and arrangement of carrier-apron resides in the fact that it is provided at its center with two su pporting-straps instead of one, as in the ordinary practice, each apron-section being carried by a suitable number of pulleys, all of which receive their motion from the common shaft 60,which is driven at its center. Thisinsures aproper cooperative movement of the apron-sections, and hence avoids the twisting or unequal straining of the apron, and therefore of the carrier-frame.
In order that the extent of throw of the carrier may be varied to suit the conditions under which the apparatus is used, the turntable is provided with a plurality of sockets or openings 68 for the reception of the depending trip-pins 30, and hence said trip-pins may be arranged in different relative positions to cause the reversal of the motion of the turn-table at the desired points.
A further advantage of the construction above disclosed resides in the fact that it may be applied to and used in connection with any ordinary separator or thresher, the drivingshaft 8 receiving motion by means of a beltpulley 69 and a suitable belt extending from any convenient rotary member of such separating or threshing machine. Furthermore, the supporting-frame as above described may be readily attached to the frame of the machine in connection with which the stacker is used without material alteration of either.
Numerous other advantages of the construction disclosed will be apparent to those skilled in the art, and it will be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
