Description

STEPHEN S. BARTLETT, OF PROVIDENCE, RHODE ISLAND.

IMPROVEM ENT `IN HARVESTERS.

Specification forming part of Letters Patent No. 47,69l, dated May 16, 1665.

.To all whom it may concern: f

Beit known that I, STEPHEN S. BARTLETT, of the city and county of Providence,` in the State of Rhode Island, have invented certain new and useful AImprovements in Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specication, in which Figure l represents a perspective view of my invention, and Fig. 2 a front view, the iinger-beam and its connections being shown in different positions.

l In the drawings, A A A A represent the main frame, supported by two wheels, B B,

both of Which maybe used as driving-wheels, if desired, the proper gearing and crank and pitman connections being added in such'cases. As the Inode of such connections is Well known to those skilled in the art, it is not necessary to describe it here.`

C is the finger-beam, the heel of which is fastened in a recess in a shoe, D, which is supported in rear by the brace, E, whose front end is hinged to ears a c on the rear of shoe D, While its rear end is swiveled in awrist-pin, b, which in turn is swiveled in ahanger, F, fastened to the inner projecting corner of the main frame.

Y The front of shoeD is supported by a metal spring-brace, G, the` inner end of which brace .is fastened, in a recess in the front of the shoe, While the outer end is fastened to a journal, c, supported so as to turn in bearings in hangers d d. To the front of journal o there is fastened a lever, H, having a catch-piece, e, on its inner sideto fit into notches f in a piece fastened to the front of the main frame.

When the lever H is in an upright position,

as seen in Fig. l, and black lines, Fig. 2, the

finger-beam rests evenly on the surface of the ground, and if drawn over the ground will conform to the uneven surface thereof, owing to the yielding of the spring-brace G and the yielding connections of the brace F. When it is desired to cause the outer end, I, of the finger-beam to press very lightly on the surface ofthe ground, the lever H is to be moved to- Ward the finger-beam, thereby depressing the spring-brace G and causing shoeD to rock up, thereby transferring thepressure of the weight of the iinger-beam to shoe D, and if the lever is moved into the position shown in red lines the outer end, I, will be elevated clear of the ground, as shown in same colors, Fig. 2. By moving the lever Hlinto the position shown in blue lines, Fig. 2, the heel ofthe finger-beam can be raised, as seen in same colors, While the lever is moved still farther out, so as to occupy the position shown in brown lines 5 then the entire finger-beam will be elevated, as seen in Fig. 2.

I represents a sectionof the tongue by which the machine is drawn, the team being attached in the usual manner. r

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

The combination, with the shoe D, of the pivotedspringbrace E, fixed spring-brace G,

lever II, and rack f, all arranged in relation to the main frame as and for the purposes described.
