A more speci?c object of the meral IB and includes generally a main support invention, therefore, relates to the provision of extra crop engageable ?ngers supported out 25 ing axle or shaft II, on which is rigidly mounted a pair of laterally spaced spiders I2, I3, carry wardly of the feathering mechanism and in ing a plurality of bat supporting shafts I4, on transverse alignment with the other ?ngers in each of which is mounted a wooden bat I5 and each row and shiftable therewith during each a row of, crop engageable ?ngers I6 fixed to the revolution of the' reel. This object is accom plished according to‘ the principles of this in 30 edge of each hat, The axle II is journaled in a pair of bearings I‘I, I8, mounted on a pair of vention by mounting ?nger supporting arms on fore and aft extending supporting arms I9, which the bat supporting shafts and extending out are secured at their rear ends by bolts 21] tothe wardly of the feathering mechanism in such a top members ZI of the side walls 22 of a harvester manner that the latter is not interfered with duringoperation. The extra ?ngers engage any 35 platform, indicated by reference numeral 23. Theforward ends of the supporting arms I9 are crops that fall between the ends of the reel bats carried on legs 24 secured by bolts 25 to the and the side wall of the platform, thereby clear ing the crops'out of this space and preventing ' platform. A cutter bar 26 extends transversely across the platform 23 beneath the reel I0 and them fromaccumulating and fouling the feather 40 severs the crops from the ?eld while the reel ing mechanism. IIJ rotates in a clockwise direction as viewed in Another object relates to the provision of extra Figure 1 to lay the harvester crops rearwardly ?ngers at the other end of the reel outside the upon the platform conveyor 21 in well-known reel spider, which can be adjusted laterally be manner. The reel axle I I is driven by a sprocket tween. the spider and the adjacent side wall of 28 over which a drive chain 29 is trained to the platform to insure that the crops in that transmit power from any suitable source (not region are ef?ciently conveyed to the platform. shown) .' The sprocket 28 is journaled on the . Still another object relates to the provision of axle II and is connected therewith through a a novel and, improved means for mounting the slip clutch 30 of conventional design. . ?ngers on the reel bats, and that is simpler and Each'of the spiders I2, I3 comprise a plu cheaper to manufacture without sacri?ce in 50 parts; durability. A relatedlobject has to do with the provision of a novel mounting clip for mounting spring ?ngers on wood bats and support the ?ngers in such a manner as to restrict excessive vibration of the latter. ' . " ' . rality of spokes 35, ?xedly secured to the axle I I by suitable mounting plates 36 and extending generally radially therefrom‘. The bat support ing .shafts' I4 are each journaled at opposite 55 ends, respectively, in a pair of bearings 31 mount 2,406,706 3 4 ed on corresponding spokes 35 of the spiders l2‘, l3. Each shaft I4 carries a bat 55, which is rigidly ?xed along one edge to the shaft by se curing straps 33. A row of crop engageable spring ?ngers I5 is out of the end 55 of the shaft 14, and can also be rotated to swing the ?nger l6a into any desired angular relation with the row of ?ngers IE on the bat l5. Preferably, the ?nger “5a is ad justed to a position in transverse alignment with secured to the opposite edge 39 of each bat. Each ?nger 16 comprises a helical coil 48 formed the shaft [4 in laterally and angularly adjusted of two turns of spring wire, a tine 4| extending position by tightening a pair of set screws 61, tangentially from one end of the coil 40, and a which‘ are mounted in suitable threaded aper the others in the row. The ?nger |6a is ?xed to supporting shank 42 extending in the opposite 10 tures in the shaft I4. Thus, the arms 58 lie in direction from the other end of the coil 40. The end 43 of the shank 42 is bent at right angles ‘to the shank and is received within a hole 44 in the bat l5. The shank 42 extends over the edge 39 of the bat and lies against the side of the bat with the coil 40 disposed adjacent the edge 39 of the bat and the tine 4| extending outwardly therefrom, all of the tines in the row lying in the planes of the associated bats l5 and swing therewith relative to the spider IS. The outer ends of the spokes 35 in the spider 53 are interconnected by an annular shield 65, preferably formed of sheet metal with‘ an in wardly turned stiffening ?ange 66. The shield ' braces the arms 35 and prevents crops from catching on the ends thereof. On the opposite end of each shaft 54 is ?xed A securing, clip 45 lies over eachsupporting 20 an actuatingrarm ‘E6 outwardly of the spider l2, and disposed at an angle to the plane of the bat shank 42 and comprises a small plate preferably ! 5. A control spider ‘H is disposed laterally out formed of sheet metal with‘ the center portion wardly of the spider '12 and comprises a- plural pressedor otherwise deformed to form a groove ity of spokes l2, the outer ends of which carry 46 on the inner side of the plate to receive the journal sleeves 13, which embrace bearings 14 shank 42, the surrounding portions of the plate rigidly ?xed by bolts ‘F5 to the outer ends of the being ?at against the hat. The lower edge of arms 19, respectively. The spokes T2 are inter the plate 45 is turned under the edge 39 of the connected at their outer ends by an annular bat to form a ?ange 4?, which is slotted to strad shield it and the inner ends are interconnected dle the shank 42. A reenforcing strip 48,'also by an annular member ‘ll. The inner ends of preferably of sheet metal, lies along the lower the spokes l2 bear on the outer surface of a cam surface of the ?ange 46 and is rigidly ?xed there ining cylinder ‘US, which is mounted on a hub 19 to, as by welding. The reenforcing strip 43 journaled on the reel axle H. The hub 19 is passes under the shank 42 and serves as a sul? ?xed eccentrically of the camming cylinder 18 port or brace for the latter. and is braced by spokes 8%. The cylinder 18 is The clip 45 is perforated at as to receive a fastening bolt 58, which is inserted through an normally held stationary by a brace rod 8 I , bolted aligned aperture 5i in the bat l5 offset from the at 82 to the cylinder 18 and extending rearwardly hole 44, and the bolt is secured by a nut 52, through‘ an apertured bracket 83 ?xed to the sup transverse alignment. “ threaded on the end of the bolt on the opposite side of the bat l5, over a washer 53. As the reel rotates in a clockwise direction dur porting arm I9. The rod 8| is threaded to re ceive a pair of adjusting nuts 84 on opposite sides of the bracket 83 to adjust the rod fore and aft ing operation, as viewed in Figure 1, the forces to swing the cylinder '68 about its eccentric axis, affecting the ?ngers due to engagement with thereby shifting" the axis of the control spider crop material tend to force the shank 42 against ‘H relative to the axis of the axle H. This the reenforcing strip 48 and against the surface 4:VI causes the arms '10 to shift angularly relative to of the groove 46. Thus, the strip 48 provides a the spider i2, thereby rocking the shafts l4 and durable fulcrum for the ?nger. Without the bats it to adjust the ?ngers 16 to various angles strip 48. the shank would press‘ or wear a notch of’ approach to the harvested crops, as is well in the edge of the bat. The groove 46 also pre known to those skilled in the art. vents lateral displacement of the ?nger, while Heretofore, the crops in the space occupied by the turned end 43 prevents the ?nger from shift the spiders l2 and ‘H, between the end ?ngers ing longitudinally of the groove. The entire ?n E5 on the bats and the side wall 22 of the plat ger and clip assembly can easily be removed by form 23 have received no positive action by the removing one bolt 50. reel. According to. the present invention, how ’ Each shaft [4 comprises a hollow tube, one end 55 ever, this portion of the crop is acted upon by 55 of which is open beyond the spider bearing 3'8. a plurality of extra ?ngers Nib disposed between Due to variations in the widths of harvester plat the control spider ‘ii and the adjacent side wall forms and to the inaccuracies in mounting the 22. Each ?nger shank 42b is welded to one end supporting arms 19, 2E9, there is sometimes an ap 85 of an arm 86 which has a supporting end 81 preciable space between the end of the reel and ?xed to the‘end of the bearing 14 and extending the platform wall 22 in which the crops are not axially outwardly therefrom. The arm‘ 86 is subject to positive action by the reel. Accord bent to form a radially extending portion 88 ly ing to this invention, this condition is remedied by ing substantially in the plane of the control arm providing an extra ?nger lea outwardly of the l6, and the end 85 is carried at the outer end of spider !3, for the purpose of positively engaging the portion 88 and lies substantially in the plane and moving any crops in this space. The ?nger of the associated bat l5. Thus, since the arm Ida: is rigidly ?xed to one arm 58 of an L-shaped member 59, preferably by welding the shank 42a thereto. The other arm 63 of the member 59 ex 86 is rigid with the bearing 14, arm 10, shaft l4, and bat [5, the ?nger l?b is carried in trans tends axially in telescoping relation to the shaft verse alignment with the row of ?ngers I6 on 14 and serves as an extension of the latter be the bat and swings angularly therewith.v In yond the spider IS. The member can be adjusted axially of the shaft M to obtain the desired clear ance between the ?nger.
