SELF-BINDING HARVESTER.

SPECIFICATION forming part of Letters Patent No. 554,030, dated February 4, 1896.

Application filed April 19, 1893. Serial No. 471,025. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES A. ANDERSON RAND, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Self-Binding Harvesters, of which the following is a full description, reference bein g had to the accompanying drawings, in which Figure 1 is a sectional rear elevation of such parts of a self-binding harvester as are necessary to illustrate my invention. Fig. I is a plan view of similar parts; and Figs. 2, 3, 5, and 6 show details of construction.

It is found necessary in all self-binding harvesters to provide space for the accumulation of the grain-straws between the elevatin g devices and the parts directly concerned in the operation of binding while each bundle is being bound. When the packing devices are in operation a continuous flow of grain takes place; but in binders of the Appleby type, in which a cut-off checks the flow of the grain during the operation of binding, a difficulty has been encountered in the tendency of the grain-straws to remain upon the upper portion of the binding-table, especially so when the latter is very nearly flat. In my machine, as well as all in which a binding attachment of the Appleby type is applied to a harvesting-machine, there maybe considered to be a primary and secondary receptacle, the former that in which the grain is received and accumulated during the operation of binding a bundle, and the latter that into which the grain is packed and bound. My improvement has to do with the primary receptacle and with the co-operation of the new parts of the primary receptacle with the secondary receptacle and the device operating in connection therewith.

I am aware that various feeding devices have been so located as to operate upon straw in the primary receptacle and force it to the secondary at proper intervals, and I shall not claim broadly a feeding device adapted to operate upon said grain; but the nature of my invention consists in making the floor of the primary receptacle act as a feeder.

A is the main wheel of a self-binding harvester, and B, B, and B port-ions of the main frame thereof.

0 is the elevating device and D the binding attachment, having the packers d and d suitably connected to the driving mechanism located upon the harvester. The binding attachment is secured to the harvester-frame by means of the sill-bars b and the brace b. Upon the main frame, in a bracket E, I journal a shaft 6, having the crank 6'. Upon the shaft is the sprocket-wheel 6 which is given motion through the instrumentality of the chain f thrown over the sprocket-wheel F, that maybe considered as continuously driven.

G is a plate forming the flooring of the primary receptacle and provided with teeth 9 and G the binding-table. The flooring G, I prefer to make about ten inches in width when applied to a full-sized machine. One edge is placed adjacent to the elevating devices, and the other lies above and laps over the edge of the binding-table. Secured beneath the forward end of the plate G is a support g. This is provided with an eye that rests upon the wrist 6 At the rear end of the board G is secured a pin g, that enters an eye in a bracket I-I, extending from the elevator-frame. This pin is loosely fitted in the eye and serves as an axis of movement for the board. It will now be understood by reference to Fig. 1 that if the crank e be passed through its rotation the board will be given an orbital movement at its forward end and the upward forward corner be thrown through the path indicated by the dotted line in Fig. 1, when properly controlled. To control the plate, I extend an arm g in a lateral direction and pivot it to the link which in turn is pivoted at g to a bracket on the main frame. By means of the arm and controlling-link the plate is held in position at its front end without necessarily coming in contact with the binding-table and any flapping or getting out of place thus prevented. It is always true that the butts of grain-straws are more inclined to hang backward than the tops, and hence it is preferable to give the forward portion of the plate G greater movement than the rear. If it is desirable, the rear end may be thrown in exactly the same manner as the front end; but I pre fer to pivot it, as shown. I have found that in order to get the feeding action, although preferable, it is not necessary to give the forward end of the board an orbital motion, and that if shaken in the direction of its plane a good result will follow, especially when provided with teeth g. I have chosen to make the latter of small pieces of sheet-iron, cut square and with the corners turned upward, as shown in the figures.

I have shown in Fig. I) the shaft E placed substantially vertical and the crank revolving on a horizontal plane and pivoted direct to the board. This form may be used; but I recommend that shown in the previous figures. As the board in the preferable form has an orbit upon an axis at the rear of the machine, it is necessary that the eye in the support g be made large enough to rest loosely upon the crank-wrist, or, if it is desirable to make it more exact in constructing, the crankwrist may be placed slightly diagonal, so that its axis shall cross the axis of the shaft upon which it is at a point beneath the universal joint g.

I is the front wall or guiding-board for the butts of the grain, which, when the machine is placed lower at front than at rear for the purpose of handling short grain, serves to prevent the grain-straws from jarring forward. Against this, when stationary, in ordinary binders short grass and weeds are likely to accumulate. My feeding receivin g-table acts to remove any such accumulation and force it onward.

hat I claim as my invention and desire to secure by Letters Patent, is-

1. In combination with the grain-delivery device the packing and binding devices, the

butt-guiding wall I and the receiving-table pivoted at its rear end and given an orbital movement at its front end and thus adapted to move the grain onward in the direction of grain travel, substantially as described.

2. The combination of the following elements: the grain-delivering devices, the receiving-plate G pivoted at its rear end and given an orbital movement at its front end to thus prevent lodgment of grain-straws and grasses thereon, and the binding-table, substantially as described.

3. In a grain-binder, and in combination with the grain-delivering devices and with the packing and binding devices, an intermediate receiver, upon which the grain is delivered, said receiver pivoted at its rear end, and given an orbital movement at its front end, and thus adapted to move the grain onward in the direction of delivery in the binding-receptacle, substantially as described.

i. In a self-binding harvester, and in combination with the grain-deliverin g devices and the packing and binding devices, an intermei diate receiving-table, pivoted at its rear end and supported upon and driven by a crank at its front end, and sustained in its position and prevented from rotation by means of the lateral arm and the link g substantially as described.
