OF A. B. CRAWFORD.

IMPROVEMENTl IN THRASHING-MAQHINES.

Specification forming part of Letters Patent No. 29,865, dated September 4, 1860 reissue No. 4,007, dated May 31, 1870.

To all whom it may concern:

Beit known that A. B. CRAWFORD, of Piqua, Miami county, in the State of Ohio, invented a new Improvement in Grain Thrashing and Separating Machines; and we do hereby declare that the followingis a full, clear, and exact description of the same, :reference being had to the accompanying drawings, making a part of this specilioation, in which- Figure 1 is a side elevation; Fig. 2, a plan view; Fig. 3, a longitudinal section through the line a', Fig. 2; Fig. 4, a view of arm e, lingers j', tooth g, and castingE; Fig. 5, a view of thimble i; Fig. 6, a view of caster; Fig. 7, a view of ball-and-socket joint.

One part of the invention of the said GRAW- FOBD consists in the attachment of a strawstacker toa thrashing-machine in such a manner that it may be transported from place to place without being detached from the machine.

Another part consists in a straw-stacker made in two or more sections, hinged together in such a manner that the upper section or sections may be extended in line with the lower one, for use in connection with a thrashing-machine, or may be folded under the lower section and secured there safely for transportation without being detached from the machine.

ln the drawings, L is the stacker, which may be made with crossties extending through the side boards, and secured 4therein by joint bolts or pins. To the cross-ties a light bottom of plank, B3, is secured. At each end of the stacker is a transverse shaft in suitable boxes, bearing two or three pulleys, by which the carrier c2 is driven, which removcsthe straw from the machine. The belt c is made with two or more longitudinal straps of leather, to which slats are nailed at intervals of fifteen or eighteen inches, so that as the straw and chai' from the thrasher fall upon the belt they can bei conveyed to the outer end of the stacker. One of the shafts, either at the upperor lower end of the stacker, protrudes through the sides of the same, and upon this shaft the driving-pulley is placed.

The stacker may be attached to the thrashing-machine in any way that may best suit the shape and style of the latter, or the will of the eonstructer. The usual way is to attach the lower end of the stacker to the maf chine, either by putting an iron eye into the sill or back part of the machine, and a hook into the stacker, and passing the hook into the eye, or by lengthening the lower shaft of the stacker. so that it extends about three inches beyond each side, on which projectings ends are journal-boxes constructed with bearings outside of lianges, which screw up against the side of the stacker, said bearings being made to work into boxes formed either on the back part of the machine, or a part attached for the purpose a few inches in the rear of the back part. The ,upper end of the stacker may be secured to the thrasher by means of hangers a, extending down from the arm of the machine, and attached to the stacker on each side by means of bolts. The upper section, when in use, is extended so as to stand in line with the Iower section.

When the sta-cker is folded for transportation, the upper section is brought under and secured to the lower section in any suitable manner. Any kind of hinge that will answer the purpose may be used to connect the sections. The kind generally used is made of `cast-iron and bolted to the sections.

Thestacker maybe driven with either chain or belt, and from either the upper or lower shaft, as may be most convenient.

Having thus described the invention of the said A. B. CRAWFORD, whatwe claim as new, and desire to secure by Letters Patent, is-

shown', 0f the folding straw-stacker L with a thrashing-machine, so that the former may be transported from place to place without being 2. The straw-stacker a, when made in two or more sections, a: m, hinged togetherin' such manner that the upper section or sections may be extended in line with the lower one, for use in connection with a thrashing-machine, or may be folded under the lower section and secured thereto, so as to be Acapable of being transported without detachment from the machine.
