V SHEAF-LOADER.

To all whom it may concern:

Be it known that I, LESLIE R. LONG, a citizen of the Dominion of Canada, residing at Tipton, in the countyyof Cedar and State of Iowa, have invented a certain new and useful Improvement in sheaf-Loaders, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention relates to harvesting machines, and primarily to that type ofthese devices which is designed to ,engageand' lift sheaves or shocks of grain from the ground and deposit them into a container as the machine travels across the field.

The invention has various objects including the provision of a means for engaging, grasping, lifting and depositing a sheaf or shock, and again lowering the lifting means to position'it to engage another shock, upon the engagement of which a repetitionofthe above outlined operation takesplacea A further object-of the invention; is the production of a means whereby the conveyer may be automatically raised and lowered, when a'shock is deposited uponthe' conveyer and deposited therefrom. It is also an object of the invention to manually control the lifting element when occasion "requires this to be done.-

The invention contemplates the? use'of-a plurality of lifting elements, which are alternately raised and lowered toconveythe sheaves from the ground and to deposit them. These lifting elements are arranged and connected together so that upon the upward movement of one the other is lowered. The above construction is such that one of these lifting elements maybe lifted and held against its downward movement without interfering in any way with the satisfactory operation of theother. This lastreferred to arrangement permits" both :of -,-the lifting elements to be brought to a'raised EPOSltlOll and locked when in this condition to facilitate the transportation of the device:%; y

The invention further (contemplates the use of a means operable from theseatfor unlocking the elevating elements to permit them to be released for operation. I

When either of these-arm's reaches its uppermost position, the, ,ch tch "which; caused it to be raisedto bui dlei'dischargingr position is automatically disengaged, in which position; it' is retained until a bundle is deposited uponthe arm is la re -a; is

In the embodiment of the invention as.

illustrated in the drawings, the use of a wagon box or body 10 having the front and rear trucks and wheels 11 and 12 is contemplated. To one of these rear wheels 12 is suitably secured the sprocket wheel 13 having the sprocket chain 14 which drives the sprocket wheel 15 arranged upon the jack shaft 16. This jack shaft is continuously rotated by the sprocket 13 and chain 14 when the wagon is drawn across the field. This jack shaft has a gear 17 which meshes with and drives the gears 18 and 19 arranged upon the

shafts

20 and 21. These shafts each have a gear 22 loosely mounted thereon, which mesh with each other and drive their

respective cable drums

24 and 25, when either of the clutches 26 or 27 is operated to connect said drums with the

shafts

20 or 21 which are continuously rotated by the shaft 16. Each of these drums has attached thereto one end of a cable 29, which extends from the drum over the pulleys and 31, and has its opposite end secured to its

respective drum

24 or 25. The gears 2222 cause the

drums

24 and 25 to rotate in opposite directions which causes one of the cables 29 to be wound upon and the other let off when either of the clutches 26 or 27 is connected to drive its respective drum. Thus one of the

arms

32 or 33 will be raised while the other is lowered to bundle receiving and discharging position, when either of the clutches is in operative position. These clutches are automatically disconnected by the

particular arm

32 or 33 which they control when the arm has reached its bundle discharging position. The clutches 26 and 27 are both under manual and automatic control, so that either arm may be lifted over any obstacle or to its bundle discharging position. The means whereby this feature may be accomplished manually include separate instrumentalities which control each clutch. Being identical only one will be explained. This means includes the foot lever 35, shaft 36 and forked clutch lever 37. The shaft 36 is journaled in brackets 38 and 39 secured to the wagon box in the usual manner. Should it be desired to lift the arm such as 32 partially or. completely, by the mechanism just described, the operator will press upon the foot lever 35. This op.- erates the clutch 26 and connects the drum 24 with the shaft 20 causing the cable 29 of this drum to be wound thereon, which lifts the particular arm to which this cable connected and lowers the other arm as 33, this lowering being accomplished by the gears 22; The clutch may be left in connection or disconnected which will cause the arm to be raised to its fullest extent, or only partially, as desired. The shaft 36 is provided with a lever arm 40 which is positioned thereon in the path of the arm, such as 32, to be engaged thereby to disconnect the clutch when the arm reaches its highest position. The arm 33 is provided with a lug 41 so that the arm 42 of the shaft 43 will be properly engaged to disconnect the particular clutch which the shaft 43 operates. These

arms

32 and 33 are provided with means for automatically throwing the clutches 26 and 27 into operation when a sheaf is deposited thereon. This means includes the arm 44 which is positioned upon the arms 32-33 in the path of the sheaf. This arm 44 has a lever 45 to which is se cured one end of a cable 46 which extends over a suitable pulley 47 and has its opposite end secured to the lever 40 or 42. Thus when the arm 44 is lowered by the sheaf, the lever 40 will be operated to throw its particular clutch 26 into operation, causing the arm to be raised and the bundle to be deposited. The clutches are thrown out of operation by the bundle carrying arm engaging its respective lever 40 or 42. Each of the

bundle carrying arms

32 and 33 has pivotally secured thereto a cradle 49 into which the sheaf or shock falls when engaged thereby. This cradle has a grasping device which engages the bundle and holds same in the cradle until the arms such as 32 and 33, to which they are attached, reach their uppermost or-discharging position. These cra- '50 is pivoted at 53 to the arms such as 32 and 33 and has the rearwardly extending arms 5454, each having a roller 55. The arms 5454 are permitted to swing'to a certain limit by the chains 56. One of these arms forms the actuating means for the grasping device which holds the bundle after it has been deposited upon the cradle. These grasping devices consist of the swinging bars 57-57 which are pivoted to the outermost end of the cradle, and are actuated by the lever 58 and the bell crank lever 59, which are connected together by the cord 60 which is fastened. to one end of the bell crank lever. The opposite end of this bell crank lever engages and rides upon one of the arms 54 of the cradle and is actuated thereby when the arm such as is raised. The grasping arm 57 is retracted by the spring 61 which releases these arms when the cradle reaches the uppermost position shown in Fig. 2. When either of the

arms

32 or 33 is raised the'downward swing of the cradle will cause the arms 54 to move. This causes the bell. crank lever to be operated closing the grasping devices around the bundle. This condition exists until the roller 55 of the arm 54 engages the plate 63.

the edge of the box This causes the cradle to be turned on its pivot, releases the grasping devices, and permits the bundle to drop into the vehicle.

Each of the

arms

32 and 33 is provided with a catch 64 which maybe hooked over the edge of the vehicle body to hold the arm and cradle in its raised position when the machine is being transported from one place to another, and the operation of the arms is not desired. This catch is prevented from operating each time the arm reaches its uppermost position by the pivoted element 65 having the ledge 66 which is in the same plane with the portion over which the catch is hooked when the arm is retained in its uppermost position. This catch rides upon the ledge and is prevented from looking the arm. The element 65 has a rod 67 which extends near the driver so that it can be swung downwardly to permit the catch to operate. This element may also be operated to engage the catch to release it from its holding position when desired. The windlass has a provision which prevents the operation of either of the drums when the arm which it operates is held in its upward position and which will not prevent the operation of both drums when this is desired. Thus the remaining arm may be raised without'operating the other drum which would unwind the cable of this drum when its particular arm is raised. To accomplish this end each gear wheel 22 is loosely arranged upon the

shafts

20 and 21 and each is provided'with a clutch 68 which is operated to disconnect the drum and gear wheel 22, permitting one of the gears to run idle without I operating its particular drum. The clutches 68 are operated by levers 68 which are con trolled by any suitable means provided at a convenient place near the operator.

From the foregoing explanation of the operation of the device it can readily be seen that as the device as a whole is operated along the ground, and one of the clutches 26 or 27 is operated, its respective drum will. be caused to revolve, winding the cable'upon' it and raising the particular arm to which it is attached, carrying the sheaf or shock over or body into which the sheaf is deposited. At this time one of the levers 40 will be operated, which disengages the particular clutch which has been previously thrown into operation. It is also evident that during the raising of one of the cradle arms the other will be lowered into position to engage another shock or sheaf.

This operation will be continued until a sufficient number of sheaves have been collected. To insure the lowering of these arms which carry the cradle, the springs 70 are provided. These springs are engaged and put under tension by their engagement with the arms 3:2 and 33, when these last named independently of the other.
