IMPROVEMENT iN|iARvEs'Ti-:Rs;

To all whom it may concern:

V13e it known that 1. MoGLIN'rooK YOUNG., Jr., of the city and county of Frederick, and State of Maryland, have invented a new and improved raking apparatus for that description of harvesting-machines which are supplied with sector-shaped platforms; and I do hereby declare that the followingis a full and exact description thereof, reference being had to the accompanying drawings, making a part of this spechcation.

Figure l is a rear elevation of the sectorshaped platform ofaharvesting-machineg Fig. 2, a top view of the same Fig. 3. an end vlew; and Fig. 4, a separate view of the pitman M, which forms a portion of my improvedy raking apparatus.

Similar letters indicate like parts in each of the drawings.

My improvement in the raking apparatus ofthe abovemeniioned description ofharvesting-machines consists in so combining the ex tremity of the handle ofthe rake with a transverse shaft that the rotation of the said shaft, when aided by a curved guiding-rod,will impart the following movements tor said rake, viz: a sweeping axial movement from the inner edge of the platform (or a little beyond the same) over to the forward portion of said platform, and at` that point changing 4to an axial horizontal movement across the same to the starting-point, and so onward in regular succession, which movements enable the'said rake to throw the cut stalks of grain in coinpact gavels from the inner edge of the platform into the path that has just been passed over by the team, and entirely beyond the reach of the team and of the machine during the succeeding movement of the same across the grain-field.

In the accompanying drawings, A marks the platform ofthe machine; B B, the stanchions which support the reel'shaft D; G, the'riin or guard around the curved portion of the platform; hl E, the arms of the reel; F F, the gatherers of the reel; H, the rakeehead; I I, the rake-teeth; J, the handle of the rake; K, auniversal joint connecting the extremity of the rake-handle with the shaft D; L, an arm onthe shaft D, which is secured in any desired position by means of the set-screw a. M is a pitman uniting the extremity of the The operation ofthe machine is as follows: As the machine is drawn along its path of. progress the reel-shaft D is caused to revolve by any suitable gearing.. The operation may De supposed to commence when the rake is at the inner edge of the plat-form, as shown in Fig. 2. The arm L and the pitinan M cause the revolution ofthe shaft D to raise the rake along its guide R, andwhen it has attained its highest point itis conducted downward to the proper position for the arm L and pitman M to carry the said rake across the platform to the starting-point, and thus the operation is continued. l

The drawings represent thehandle J of the rake II as being connected to the reel-shaft D ot'aharvesting-machine; butit is obvious that the arrangement and construction of the parts may be varied by ordinary mechanical skill without departing from the principle of my invention. Therefore I do not intend to restrict myself to the precise arrangement ofthe parts which connect the rake-handle with its operating-shaft, provided the said apparatus is of such a character that the revolutions ot' said shaft will impart to the rake the within-described continuous axial movements over and across a sector-shaped platform.

The gatherers F are secured to the arms of the reel-shaft by means of staples and setscrews in such a manner that the said gatherers may be adjusted to any desired position without varying the position of the reel-shaft. Having thus fully described my improved raking apparatus for that description of harvesting-machines which are furnished with sector-shaped platforms, what I claim therein as my invention, and desire to secure by-Letters Patent, is-,

Connecting the handle of the rake to a transverse shaftin such a mannerthat the rotation ot said shaft when aided by the curved guiding'- rod R or its equivalent, will impart the withindeseribed movements to said rake-viz., a
