WILLIAM N. WHITELEY, OF SPRINGFIELD, OHIO.
IMPROVEMENT IN MOWING-MACHINES.`
Specification formingpart of Letters Patent No. 154,936, dated September 8, 1874; application filed May 26, '1874.
, vesting-machines wherein the points of the cutting apparatus are capable of adjustment up or down to adapt them to the condition of the grass or grain against which they are to act 5 and it consists, principally, of a shoe at the inner end of the cutting apparatus, hinged at its rear end to a drag-bar, and provided with a lever, whereby its front end may-be raised or lowered, and a holding device or keeper, so located that the relative adjustment of said shoe to said drag-bar will not be chan ged by the rising or falling of the cutting apparatus as it advances over the undnlations of the ground.
That others may fully understand my invention, I will particularly describe it.
The main frame is mounted upon driving and supporting wheels, and bears the gearing necessary to transmit the motion of said driving-wheels to the cutting apparatus and raking mechanism.
A is the inner shoe, to which is securely bolted the linger-bar B of the cutting apparatus. The drag-bar O extends beneath the shoe A, and is hinged to the same at its rear, and said hinge is conveniently formed by turning the extremity of said drag-bar over a horizontal pin, p, which forms the pintle' of the hinge, the ends of said pin being held in lugs made on the rear end of said shoe for that purpose. To the front end of the shoe A a lever, D, is secured, and said lever extends forward over the drag-bar to a point where it can be reached by the drivers hand, so that he can raise or lower the front end of the shoe A, and thus adjust the position of the points of the fingers and cutters. A latch, E, operated by a thumb-piece, F, land spring G, is attached to said lever D, and engages with a segment-rack or keeper, H, to hold said lever at the desired point as to elevation.
The segment H may be a cast plate, to be secured to the drag-bar, preferably immediately in front of the point of the shoe A, and constructed with a vertical slot, wherein said point may rest, or through which the lever D may pass to serve as a. guide for the front end of said shoe, and to support it against the lateral strain produced by the resistance to the advance of the cutting apparatus.
This improvement is adaptedto machines for eitherreaping or mowing. When employed for reaping, the raking mechanism will be mounted upon the shoe A, so as to partake of all its movements.
In addition to the facility of adjusting the points of the cutters and guards, this device serves to keep the cutters and guards in fixed relation to the drag-bar and surface of the ground, said relation being unaffected by the rising or falling of the cutting apparatus as it passes over the ground.
This is not the efeet in those machines wherein the adjustment of the points of the guards is effected by a lever situated upon the main frame independent of the drag-bar, because the movements of the cutting apparatus lare not in correspondence with the movements of the said frame, and, therefore, there will be no fixed relation between the lingers andeutters and the drag-bar.
Having described my invention, what I claim as new is- The shoe A, having the lever D rigidly attached to its front end, said lever provided with a latch, E, in combination with the dragbar C, having the notched and slotted segment H, to guide the shoe and maintain the same in adjustment upon the drag-bar, substantially as set forth.
