In addition to this, the different lengths of This auxiliary belt of Elward's acts much in the stalks required some means whereby the the same way, in relation to grain movid binding band might be placed centrally to by and on the horizontal apron, that the austheir lengths; that is, if the stalks, after iliary belt of Olin does upon grain carried being cut, are 12 inches long, the band upward by the main horizontal belt, shoving should be placed about 6 inches from each the grain endwise towards the rear of the end, but if the stalks are 5 feet long it should machine while it is being carried along.

To method is stated, however, by which the capobviate the difficulty of the butts lagging be vas may be rotated, and, even if it were, it hind, and also to secure proper delivery of would still be incompetent to perform the the grain as to length, Olin invented an aux office of the Olin belt, because it is not ad. iliary belt, located at a right angle to the justable at either end. main belt, but moving in the same direction, The patent to George F.

The mechanism was intended to act er stalks. Instead of operating to hasten upon the swath of flowing grain, and change the butts, it can only operate to retard them its direction, pushing the stalks endwise, so to the extent of the friction between the butts, that they might be delivered to the binder and the surface of the board. in proper position to be bound in their center, • The patent to C.

The claim describes this ceeding at the same speed. The horizontal swinging elevator as pivoted at its lower belt carrying the grain over the harvester end, with suitable devices for shifting its platform is described as traveling faster than upper end, whereby it forms a means for the main elevator, so as to operate to elevating the butts of the grain, and deliver- straighten the grain, or bring the stalks par ing grain of different lengths at the same allel to each other before beginning their aspoint.

The important feature, how in this connection that, by the lower end ever, connected with all these prior patents, of the swinging elevator is in reality meant is found in the fact that the devices described the receiving end, and that, as the defend. in them were all located on the grain side ant's device (which can hardly be called an of the elevator, and were designed to secure elevator at all, since it facilitates the descent parallelism in the stalks as they mounted of the grain) is pivoted at its receiving end, the main belt, and before they reached its which happens to be its upper end, it is apex.
