CONVEYER-GEARING FOR HARVESTERS.

SPECIFICATION formingpart of Letters Patent No. 486,900, dated November 29, 1 892.

Application filed February 4, 1892. Serial No. 420,309. (No model.)

Z'o @ZZ whom it may concer-12,:

Beit known that I, GEOEGESGHUBERT, a citizen of the United States, residing at Walnut, in the county of Bosque and State of Texas, have invented a new and useful Gearing for ILIarvester-Conveyers, of which the fol lowing is a specification.

This invention relates to improvements in a reciprocating conveyer for harvesters and binders in which arms fold beneath the upper plate of the platform for their grainward movement and unfold for their stubbleward movement, and a gear-shifting mechanism so constructed as to be placed beneath the upper plate of the platform and operated by a lug secured to the conveyer-chain, and a starting or tripping device by which the conveyer is started.

My improvements refer, first, to the construction of the conveyer-arrns and a track to fold such arms grainward to the chain for their grainward movement and to elevate such arms for their stubbleward movement; second, to construct a shifting-bar with an inclined slot adapted to receive a bearing to engage or disengage gearing to operate the conveyer; third, to the construction of a shifting device operated by the driver, by which he can readily determine the quantity of grain on the platform by the weight of said grain, so that the driver after a little practice will be able to trip the conveyer nearer the right time to obtain sheaves of about the same size, and, fourth, to secure compactness and etticiency in such mechanism and promote simplicity and cheapness in the construction of Vsuch mechanism.

Figure 1 is a plan view of a harvester-platform provided with my improvements. The upper plates of the platform are broken away in different parts to show parts below7 in full lines. Fig. 2 is a sectional view on line l l of Fig. 1, showing parts beyond in full lines. Fig. 3 is a subbleward end view of Fig. l. Fig. 4 is a horizontal section on line 3 3, Fig. 3, with parts below shown in full lines. Fig. 5 is a view of the platform and tripping mechanism from the rear. Fig. 6 is asectional view and brackets'beyond the section-line. is a detail View of the shifting-bar.

9, l0, 11, and l2 are detail views of the brackets carried by the shifting-bar. Fig. 13 is a detail view of the movable bearing and its antfriction-roller. Fig. 14 is a view of the trip-lever. Figs. 15 and 16 are detail views of the conveyer-arms. Fig. 17 is the same as Fig. 6, with the gearing disengaged and the trip-lever and other parts omitted; and Fig. 18 is a detail plan View of one of the lockingdogs.

In the drawings, A designates the lower plate of the platform, secured, with its front edge, to the lower flange of the finger-bar A3.

A is the upper front plate of the platform, and A2 is the upper rear plate of the platform. The front plate A is secured, with its front edge, to'the front and upper fiange of the finger-bar A3 and the strip A4 and rests, with its rear edge, at the stubble end on the block e and at its grain end on the block b4.

b5 designates a strip extending from near the shaft a to the grain end of the platform. Said strip is placed far enough to the rear of the conveyer-chain to provide room for the conveyer-arm and its antifriction-roller d5,

D designates a cross-bar pivoted on the fulcrum e on the rear edge of the plate A and on the grainward'side of the shaft d and extending with its longer end rearward beyond the rear edge of the platform. Its front end has a short crook grainward, and then extends forward with its end flush with the front edge of the tinger-bar, as shown in Figs. 1 and 3.

c is a strip secured on the grainward side of the bar D with its lower edge yprojecting downward in position to be engaged by the shoulder f7 of the shifting-bar.l

D is a bar pivoted with its front end to the grain-board 57 near the rear edge of the plate A and just above said plate A and'extending rearward the saine distance as the bar D. The rear ends of said bars D and D are perforated, as shown, to receive bolts.

D2 are strips secured to the bars D and D by suitable bolts passed through any of the perforations. Any number of strips D2may be employed and shifted to any of the perforations in the bars D and D to receive long or short grain.

D3 is a bell-crank pivoted to near the upper edge of the vertical iiange of the plate A2 on the grainward side of the bar D with its upper arm connected by a rod D6 to a lug D7, secured to the under side of the bar D, with the lower arm connected by a rod D4 to the toggle-joint D5. Said toggle-joint is formed of two arms, with one arm pivoted to the lower edge of the rear of the platform and with its upper arm pivoted to the lug D8, secu red on the under side on the bar D', so that when the bar D is elevated the rod D4 will be drawn stubbleward, and thus drawing straight the toggle-joint and elevating the rear end of the bar D simultaneously with the bar D.

g designates a triplever pivoted in a slot g3, formed in the plate A-and in the strip A4 on a pin g4, passedy through thev strip A4 and IOO one of the perforations in the lower end of the trip-lever, curved upward in position to rest, with its heel, on the front end of the bar D, and thencev bent to project vertically and perforated near its upper end. g is a drawrod secured in one of the perforations in the lever g and extends, with its other end, to a foot-latch usually secured to, the operators foot-board. (Not shown in the drawings.) By changing the pin g4 to one of Lthe different perforations in the horizontal end of the trip-lever or changing the draw-rod g to different perforations inthe vertical end of said trip-lever g the pressure on the draw-rod can -be adjusted as the operator may see necessary.

The operation may be summarized as follows, viz: The shaft h4 receives its power from IZO the harvester-gearing (not shown in the drawings) and rotates the bevel-pinions h and h2 in one direction, as indicated. When the conveyer is at rest, the gear-shifting bar is in the position as seen in Fig. 17, with the shoulder f7 in engagement with the strip c. When the desired quantity of grain has accumulated onv the platform, which is readily determined by weight after a short practice, the operator allows the draw-rod to shift grainward, thus allowing the front end of the bar D to elevate, allowing the rear end of the bars D and D to lower to the platform and allowing the grain to rest fiat on the platform. vAs the front end of the bar D is elevated the projection c is disengaged from the shoulder f7 of the shifting-bar, thus allowing the spring K to move the shifting-bar grainward until the collar f5 is adjacent the bracket f4, when the spring-pressed hook t6 of the doge4 will have engaged with the notch f2 and lock the gearshifting bar in position. As the gear-shifting bar is thus shifted grainward the inclined slot f', carrying the bearing t" of the shaft a, will lower said bearing t', and thus engage the bevel-pinion h6 with the bevel-pinion h2,-

thereby starting the conveyer. As the conveyer is started on its stubbleward movement the roller d5 is guided to the top of the plate A2 by the guide d6 moving the free end of the arm d and d slightly stubbleward, as seen in Fig. 2. As the conveyer moves stubbleward the lug Z7 on the chain b moves against the rearward-projecting end j2 of the lever j, depressing said end, and thus elevating its grainward end and disengaging the rearwardly-projecting end J8 of bracket J from the studj. Said bracket J will now be moved against the shoulder f7 by the spring K. vAs the conveyer nears the end of its stubbleward movement the lug 0V moves against the end J5 of the bracket J, moving it stubbleward, thereby compressing the spring K, and as the projection J 2 on the lower stubbleward end of the bracket J moves past the stud j@ it will come in contact with the grain end of the dog 4, pressing it forward, thus disengaging the hook t6 from the notch f2and unlocking the shifting-bar. The spring K, being compressed, will now move the shifting-bar and the bracket J stubbleward, thereby disengaging the bevel-pinion 71,6 from the bevelpinion h2 and engaging it with t-he bevel-pinion h', thus reversing the movement of the conveyer. As the shifting-bar is thus moved stubbleward until the collar f6 is adjacent the bracket f4 in position, as seen in dotted lines in Fig. 1, the dog '2 engages with the shoulder flo and locks said shiftingbar in position. As the conveyer starts on its grainward movement the lug d'7 on the chain moves against the rearward-proj ecting end of the lever J2, depressing said end and elevating its opposite end, thereby disengaging the rearwardly-projecting end J5 of the bracket J from the stud j, and as the conveyer nears the grain end of its movement the lug di' moves against the end of the bracket J and moves it grainward over the stud j5, and as the projection J on the bracket J passes over the stud ,7'5 the projection J 6 on the grain-l ward end of the bracket J moves against the lever g5, shifting it forward, and thus disengaging the dog 2 from the shoulder f 10, when the spring K will move the shifting-bar grainward until the shoulder f7 thereon comes against the projection c, as seen in Fig. 17,

when the bevel-pinion h6 will be disengaged from the bevel-pinion h and the movement of the conveyer ceases until again started by the operator, as heretofore stated. As the conveyer nears the stubble end of its movement the roller d5 of the conveyer will pass through the notch n beneath the plate A2, and as the conveyer starts on its grainward movement the roller d5, detained by the spring d8, will fold the arms d and d grainward until the projection d2 rests on the upper strand of the chain b', when the roller 07,5 will be drawn through underneath the spring d8, when the arms d and d will'be in position, as seen in dotted lines in Fig. 5. As the conveyer thus folded nears the grain end of its movement the free end of the arms d and d come in contact with the guides h6 and are partly unfolded or elevated, and at the time that the roller d5 passes from under the guide or spring d the grainward movement of the conveyer ceases. The spring K is coiled close enough on the shank f2 so that it is entirely 'compressed at the time the shifting-bar is unlocked, so that the conveyer will act by the bracket J or J direct on the shifting-bar and shift said shifting-bar until the gearing is disengaged in case the spring K should fail to do so. Thus no breakage can occur.
