IMPROVEMENT IN GRAIN-CARRIERS FOIR HARVESTlNG-MACHINEQS.

Specification forming part of Letters Patent No. 6,540, dated June 19, 1849.

To all lwhom it may concern:

Be it known that we, JACOB I. MANN and HENRY F. MANN, of Clinton, in the county ot' La Porte and State of Indiana, have invented certain new and useful Improvements in Conveying Straw'and Grain from a Reaping-lllachine; and we do hereby declare that the following is a full, clear, and exact description ot' the principle or character which distinguishes them from all other things before known, and ofthe usual manner ofmaking, modifying, and using the same, reference being had to the accompanying drawing, which represents an isometrical view ofthe machine.

The nature of our invention consists in con-l resented in the drawing is in most particulars like that known as McCormicks, with the eX- ception ot' the straw or grain carrier, which is constructedin the following way: We place near each side of the platform @,just behind the cutter b, two shafts, having on them a series of pulleys, d, on which the endless bands e are carried. These bands on their upper sides traverse on a level with the platform and in a lateral direction. They are armed at intervals with projecting pins or teeth, that stand up perpendicularly from their surface. Their number is sujcient to take hold of and carry to one side all the grain and straw that falls on the platform. The inner one of the two ahove-named shafts has double the number of pulleys upon it that the outer one has, and around each alternate pulley on this shaft there is a similar endless band to those on the platform a. These last-named bandsf are extended upward in an inclined direction to the top of the frame of the machine on that side, there being an inclined plane, g, under them,

like the platform a. At their summit they pass around a series of larger pulleys on a shaft, h, and the plane g, following the curve of the pulleys and filling the space between them on their upper side,inclines down in the op,- posite direction at lc to the edge of the frame. Just below, at this point, there is a receiver, m, composed of a shaft in proper bearings atfixed to the side ot' the frame, from which three (more or less) wings radiate, and form three triangular troughs, one'of which is always np, ready to receive the straw from theinclined plane k. The shaft ot' this receiver, beyond the bearing at the front end, is made triangular,and astoutplate spring,n, bears upon it to hohl the receiver in place. There is lalso on the same shaft a hand-wheel, p, by which the receiver is turned to discharge the load when suiieiently tilled to make a bundle. The

upper shalt, h, is connected with the driv ing-wheel@ by crown-gearing r, and conveys motion to the cutters by means of the spurwheel sin a manner similar to those machines now in use, a description of which is therefore omitted.

The machine to be used may have the fore vwheels of a wagon attached to it at t, by which it is drawn.

` Having thus fully described our improvements and their mode of operation, what we claim therein as new, and for which we desire to secure Letters Patent, is-

1. The employment, in combinatiomof a dou- 'ble series of endless bands, c e andff, con- JACOB I. MANN.
