fiPECIFICATION forming part of Letters Patent No. 482,758, dated September 20, 1892. Application filed March '7, 1892. Serial No. 423,994. (No model.)

To all whom it may concern.-

Be it known that I, Gnonen ScHUBEnr, a citizen of the United States, residing at alnut, in the county of Bosque and State of Texas, have invented a new and useful Grain- Binder, of which the following is a specification.

This invention relates to improvements in a grain-binder of a kind known as a platform-binder, in which the cord-carrying arm orneedle andneedle-operating mechanism are placed below the upper deck of the platform, and the cord-tying mechanism is placed above the upper deck of the platform.

The objects of my improvements are, first, to construct a needle in sections, and to construct mechanism to curve said needle in position to a proper curvature to conform to the sheaf to be bound at the beginning of the binding operation, and to again straighten out said needle at the end of the binding operation, so as to pass beneath the upper deck of the platform, so that the grain can be shifted direct from the grain-receiving platform on the needle by a suitable conveyer invented by myself and patented February 17,1891, No. MGATS, thus dispensing with all packing and elevating and receiving mechanism, thus promoting simplicity and cheapness of the construction of such grainbinders; second, to construct a simple, light, and durable clutching mechanism to connect and disconnect the binding mechanism with the harvester or conveyor gearing; third, to construct a simple gear-shifting mechanism to impart reciprocating movement to the conveyer, and, fourth, to construct a light and simple locking mechanism to lock the gearshifting mechanism in position after being shifted to the desired position. i attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a plan view of a harvester-platform provided with my improvements. The upper front plate of the platform and the breast-board are removed to show parts below. Fig.2 is a front elevation viewof Fig. 1. Fig. 3 is a vertical cross-section view taken on line 2 2 of Fig. 1, looking grainward. Fig. 1 is a vertical longitudinal section view taken on line 1 1 of Fig. 1, showing the grainward section of the needle locked in position to compress the'grain and also showing the needle at its farthest upward movement in dotted lines. Fig. 5 is a portion of Fig 2, with the binding mechanism started by the conveyer, and the conveyer shown at near the stubble end of its movement. Fig. 6 is a vertical cross-section view; taken on line 3 3 of Figs. 1 and 2, looking stubbleward. Fig. 7 is a vertical cross-section taken on line 44 of Fig. 1.

The operations may be summarized as follows, viz: The shaft 75 receives its rotation from mechanism of the harvester (not shown in the drawings) and is rotated in the direction as shown by arrow in Fig. 1. When the operator desires to start the conveyer, he draws the draw-rod S stubbleward, thus drawing the incline guide it in the same direction and engaging the bevel-pinion j with the bevel-pinion K and starting the conveyor on its stubbleward movement, and as the conveyer moves stubbleward the projection 75' moves against the rearward-projecting end of the rod n, moving it along stubbleward, thereby compressing the spring n and shifting the rod m in the same direction, when the stubble end of said rod m will ascend on the inclined block 71 thereby elevating the stubble end of the rod on and causing it to elevate the rear end of the lever L, thus disengaging said lever L from the shoulder L when said lever is moved in the position, as seen in dotted lines in Fig. 1, by the springn', when said lever L will drop over the shoulder L and thus is locked in position. As the rear end of the lever L is moved stubbleward the rod K is drawn in the opposite direction, thereby disengaging the bevel-pinion 7' from bevel-pinion K and engaging it with the bevel-pinion K thus reversing the movement of the conveyer. As the conveyer nears the stubble end of its movement the beveled end 75 of the blockt engages beneath the free end of the needle and elevates the same to the extent as shown in Fig. 5, drawing the connecting-rod 7F, and thereby imparting a slight rotation to the shafts g and e, and moving the bell-crank g connecting-rod g and sprocket-wheel g in the position as seen in Fig. 5, and moving the arm f past the extension f allowing the arm f to descend and hold the grain untilgrasped by the needle. The slight forward movement of the shaft 9 moves the arm g off the clutch J allowing the spring J to move the sprocket-wheel J 6 outward or forward in line with the sprocket-wheel g causing the clutch J to engage with the pin J The spring 9 prevents the gearing from having any rearward movement, and as the rotation of the shaft J is reversed the clutch J will be operated by the pin J and cause the sprocketwheel g to complete one revolution, when the arm g will again engage with the clutch J and force the sprocket-wheel J 6 to the rear and disengage the clutch J from the pin J when the binding mechanism will remain at rest in the position as seen in Fig. 2 with the arm f in contact with the extensionf, holding the armf at an elevation, as seen in Fig. 2, until again started, as heretofore described. As the binding mechanism is operated by the sprocket-wheel J 6 the section h is first moved upward by the arm h and connecting-rod 72 to the curvature, as shown in Fig. 4, when the curved end of the connecting-rod 7t will come in contact with the rear end of the section h and prevent said section from having any further inward movement. At this time the forward end 2' of the connecting-rod 7t will pass from under the bracket 2' and ascend through the notch i in the plate A bypressure of the arm its on the connecting-rod h the section h is caused to elevate, and as the free end of the section h begins to elevate the spring i is released and engages with the stud 1) and locks the section h and connecting-rod 72- in position, when the needle is in position to be moved upward, as shown in dotted lines in Fig. 4:, to compress the gavel and deliver the cord to the knot-tying mechanism. (Not shown in the drawings.) As the section 7L nears the end of its return movement the spring i comes in contact with the post i and is pressed against the section h, and thus disengages the projection i, when the end i will be in position to again engage beneath the bracket 2' and compel the section 71' to unfold grainward to the position as seen in dotted lines in Fig. 2. As the conveyer nears the end of its grainward movement the projection t comes in contact with the rearward projecting end of the rod m and draws said rod m grainward, the dog of shifting along on the smooth surface of the block n with its IIO free end projecting grainward until it comes in contact with the shoulder at projection 12*, when it will be drawn over and elevate the stubble end of the rod m and the rear end of the lever L, and disengaging said lever L from the shoulder L the near end of said lever L will now be moved grainward by reason of the dog n or eye of the rod 111. resting against the lug L and thus disengaging the bevelpinion 7' from the bevel-pinion K and allowing the conveyer to remain at rest until again started by the operator, as heretofore dea projecting stubbleward and a short distance stubbleward from the shoulder L as seen in Figs. 1 and 9, and with its stubble end formed inclined and extending a short distance past the opening L J designates a shaft extending through the strip a near the stubble end of the platform and journaled with its rear end in the sill 6L2 and with its front end in the bearing J The front end or periphery of the pivoted bearing J is machined and journaled in the rearward-projecting iiange J of the bearing J*, as shown in the dotted lines in Fig. 1, and having its rear end supported on the shaft J.

The operations may be summarized as follows, viz: The shaft receives its rotation from mechanism of the harvester (not shown in the drawings) and is rotated in the direction as shown by arrow in Fig. 1. When the operator desires to start the conveyer, he draws the draw-rod S stubbleward, thus drawing the incline guide it in the same direction and engaging the bevel-pinion j with the bevel-pinion K and starting the conveyer on its stubbleward movement, and as the conveyer moves stubbleward the projection 6 moves against the rearward-projecting end of the rod 71, moving it along stubbleward, thereby compressing the spring 72' and shifting the rod on in the same direction, when the stubble end of said rod m will ascend on the inclined block 71?, thereby elevating the stubble end of the rod m and causing it to elevate the rear end of the lever L, thus disengaging said lever L from the shoulder L when said lever is moved in the position, as seen in dotted lines in Fig. 1, by the spring n, when said lever L will drop over the shoulder L and thus is locked in position. As the rear end of the lever L is moved stubbleward the rod K is drawn in the opposite direction, thereby disengaging the bevel-pinion j from bevel-pinion K and engaging it with the bevel-pinion K thus reversing the movement of the conveycr. As the conveycr nears the stubble end of its movement the beveled end 15 of the block if engages beneath the free end of the needle and elevates the same to the extentas shown in Fig. 5, drawing the connecting-rod 7V, and thereby imparting a slight rotation to the shafts g and e, and moving the bell-crank g connecting-rod g and sprocket-wheel g in the position as seen in Fig. 5, and moving the arm f past the extension f allowing the arm f to descend and hold the grain untilgrasped by the needle. The slight forward movement of the shaft g moves the arm g ofi the clutch J allowing the spring J to move the sprocket-wheel J 6 outward or forward in line with the sprocket-wheel g causing the clutch J to engage with the pin J The spring g prevents the gearing from having any rearward movement, and as the rotation of the shaft J is reversed the clutch J will be operated by the pin J and cause the sprocketwheel g to complete one revolution, when the arm g will again engage with the clutch J and force the sprocket-wheel J 6 to the rear and disengage the clutch J from the pin J when the binding mechanism will remain at rest in the position as seen in Fig. 2 with the arm f in contact with the extension f holding the armf at an elevation, as seen in Fig. 2, until again started, as heretofore described. As the binding mechanism is operated by the sprocket-wheel J 6 the section h is first moved upward by the arm 77. and connecting-rod 71 to the curvature, as shown in Fig. 4, when the curved end of the connecting-rod 71. will come in contact with the rear end of the section h and prevent said section from having any further inward movement. At this time the forward end i of the connecting-rod h will pass from under the bracket 01 and ascend through the notch i in the plate A bypressure of the arm h on the connecting-rod 7t the section h is caused to elevate, and as the free end of the section h begins to elevate the spring 2' is released and engages with the stud i and locks the section it and connecting-rod 7% in position, when the needle is in position to be moved upward, as shown in dotted lines in Fig. 4, to compress the gavel and deliver the cord to the knot-tying mechanism. (Not shown in the drawings.) As the section h nears the end of its return movement the spring 1' comes in contact with the post 2' and is pressed against the section it, and thus disengages the projection '5, when the end 2' will be in position to again engage beneath the bracket i and compel the section 71 to unfold grainward to the position as seen in dotted lines in Fig. 2. As the conveycr nears the end of its grainward movement the projection t comes in contact with the rearward projecting end of the rod 117. and draws said rod m grainward, the dog 01. shifting along on the smooth surface of the block 71 with its free end projecting grainward until it comes in contact with the shoulder at projection 77;, when it will be drawn over and elevate the stubble end of the rod on and the rear end of the lever L, and disengaging said lever L from the shoulder L the near end of said lever L will now be moved grainward by reason of the dog 71, or eye of the rod m resting against the lug L and thus disengaging the bevelpinion 7' from the bevel-pinion K and allowing the conveyer to remain at rest until again started by the operator, as heretofore described. The spring a is coiled close enough on the rod m so as to be entirely compressed at the time the lever L is disengaged from the shoulder L to allow the conveyer to act direct on the lever L and the gear-shifting mechanism to disengage the gearing if the spring a should fail to do so.

It will be understood that I do not wish to limit myself to the precise proportions and details of construction herein described, as I am aware that many modifications mav be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
