THRASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,801, dated May 7, 1889.

Application filed March 5, 1889. $erial No. 301,816. (No model.)

To all whom it may concern.-

Be it known that I, LEVI BRONSON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York,

have invented new and useful Improvements in lhrashing-l\fachines, of which the following is a specification.

This invention relates to the feed-tables of portable thrashingmachines upon which the straw is placed and from which it is fed to the thrashing-cylinder by an attendant standing upon a platform at the front end of the machine. This platform is usually hinged at its inner end, so that in moving the machine from place to place the platform may be swung upwardly out of the way to make room for the draft-animals. To permit this movement of the platform, the projecting feed-tables, which in their operative position stand in the way of the elevated platform, were heretofore detachably secured to the machine, so that they could be temporarily removed; but this is undesirable, as considerable time is lost in attaching and removing the tables, and because they are liable to be lost or broken by falling from the machine, the detached tables being usually thrown on top of the machine in moving the latter.

The object of my invention is to overcome these objections; and it consists to that end of a feed-table permanently attached to the machine and made movable, so that it may be shifted out of the way when it is desired to raise the platform.

In the accompanying drawings, consisting of two sheets, Figure 1 is a side elevation of the front portion of a thrashing-machine provided with my improvement, the front axle being shown in section. Fig. 2 is a top plan view of the front portion of the machine, showing one of the feed-tables in an operative position and the other moved inwardly. Fig. 3 is a front elevation of the machine. Fig. 4 is a fragmentary cross-section, 011 an enlarged scale, of one of the feed-tables and the adjacent frame of the thrashing-machine.

Like letters of reference refer to like parts in the several figures.

A represents the casin g inclosing the thrashin g-cylinder, and a the inclined d elivery-board upon which the straw is fed to the thrashingcylinder, and which is secured between two longitudinal beams, to, overhanging the front portion of the machine.

13 represents the platform upon which the attendants stand who cut the bands of the sheaves and feed the straw to the cylinder, the platform having the usual lateral extensions, B B, which may be swung inwardly out of the way in transporting the machine. This platform is secured to two arms, 0 c, which are pivoted at their inner ends to the lower front end of the machine, so that the platform may be swung upwardly into the position shown by dotted lines in Fig. 1, so as not to obstruct the space which is occupied by the draft-animals.

The platform, when lowered, is supported at its outer portion by rods or hangers (l, attached to the platform and having at their upper ends hooks which engage in eyes secured to the overhanging beams a, as shown in Fig. 1.

E E represent the feed-tables arranged on opposite sides of the inclined delivery-board a, with their inner portions adjacent to said delivery board, and projecting with their outer portions forwardly beyond the delivery-board, so as to be in convenient reach of the attendant standing upon the platform B. These feed tables are capable of sliding lengthwise on the frame of the machine, so that they may be drawn outwardly into an operative position, as shown by full lines in Fig. 1 and the lower portion of Fig. 2, or be moved inwardly, as shown by dotted lines in Fig. 1 and by full lines in the upper portion of Fig. 2, so that their outer portions will be retracted and allow the platform to be swung upwardly against the beams a. Each feedtable is permanently attached at its inner longitudinal portion to a horizontal rod, f, extending lengthwise of the machine and secured in lugs attached to the beams to, the feed-table being provided with perforated ears or lugs, through which the rod f passes, as shown in Fig. 4. The feed-tables ,are supported in a horizontal position by a transverse cross-bar, g, secured to the outer ends of the beams 01., and having its end portions projecting beyond the sides of the machine.

The rear outer portion of each feed-table is supported by an inclined rod or brace, h, pivoted at its lower end to the feed-table. These rods 7L are so pivoted to the body of the machine that in either position of the feedtables they will stand in an inclined position on either side of a perpendicular line drawn through their pivots, so that the weight of the tables will have a tendency to retain the rods in position, and thereby, in a measure, hold the tables in place againstinward or outward movement.

The outer portions of the platform-extensions B are preferablysupported by hooks i, attached to the extensions and engaging with eyes secured to the outer ends of the feedtables.

Upon disengaging the hooks 2' from the feedtables and the hangers (Z from the beams to the feed-tables can be shifted inwardly and the platform be raised out of the way to make room for the draft-animals. The platform is held in an elevated position by engaging the hooks or hangers (Z in eyes or lugs j, secured to the outer depending sides of the delivery board a, as shown in Fig. 1.

The feed-tables preferably consist of two or more hinged sections, as shown, so that the tables may be folded together to enable the machine to pass through narrow doorways or between rows of stacks separated by a narrow passage.

By my improved construction the feed-tables are permanently attached to the machine, whereby loss and breakage of the tables and the inconvenience and waste of time attending their attachment and removal are avoided, while enabling the tables to be conveniently and quickly shifted when itis desired to draw the machine to another point of the field.

By making the feed-tables movable the machine is also rendered more compact for shipping, and the tables are less liable to be broken in transit.

I claim as my inven tion 1. In a thrashing-machine, the combination, with the frame and the tln'ashing eylinder, of a feed-table arranged adjacent to the thrashing-cylinder and made movable lengthwise of said frame, substantially as set forth.

2. In a thrashing-machine, the combination, with the main frame and a platform pivoted thereto and capable of swinging upwardly, of a feed-table arranged above said platform and made lengthwise movable on the frame, whereby the table may be shifted out of the way to permit the platform to be raised, substantially as set forth.

In a tln'ashing-machine, the combination, with the main frame and a platform pivoted thereto and capable of swinging upwardly, of a feed-table arranged above said platform and capable of sliding lengthwise of the machine, horizontal rods attached to the frame of the machine upon which said table slides, and a support whereby the table is held in a horizontal position, substantially as set forth.

at. In a thrashing-machine, the combination, with the main frame and a platform pivoted thereto and capable of swinging upwardly, of a feed-table composed of hinged sections and capable of sliding lengthwise of the machine, horizontal rods attached to the platform of the machine upon which said table slides, and a support whereby the table is held in a horizontal position, substantially as set forth.

5. In a thrashing-machine, the combination, with the main frame and a platform pivoted thereto, of a feed-table, E, arranged above said platform and capable of sliding lengthwise of the machine, and an inclined support ing-rod, 71, attached at its upper end to the feed-table, and pivoted at its lower end to the frame of the machine, substantially as set forth.

\Vitness my hand this 24th day of January, 1889.

LET BRONSON. Vitnesses:
