Claims

Claim 1st. A harvesting machine in which the main wheel revolves upon the axle supported in bearings on either side of the said wheel, the lifting lever rigidly secured to the axle, in combination with a sheaf also secured to the axle and connected by a chain to the inner side of grain table for the purpose of raising and lowering it. 2nd. In a harvesting machine in which the grain table and cutter-bar move independently of the main frame, the combination of a solid piece of metal bolted to the cutter-bar and forming a cross head arranged to connect and move vertically within'the main frame, forming at the same time a double bearing for carrying the spindle of the rake driving pinion. 3rd A harvesting machine in which the movement of the rake wheel is derived through a sprocket wheel and pinion, rigidly securing together or forming in one piece the said sprocket wheel and Pinion, for the purpose of preventing any twisting strain being exerted on the spindle supporting the same. 4th. A harvesting machine in which the grain table and cutter-bar move independently of the main frame and is provided with a casting bolted to the inside of the grain table, arranged to form a sliding cross-head connecting the table and main-frame,. a lifting lever pivoted on the said casting, in combination with a chain or rod connected to the said lever and passing through a hole made longitudinally in the cross-head to the bottom of the grain table along which it passes over suitable friction rollers to the grain wheel for adjusting the same, 5th. In a harvesting machine in which the table and cutter bar move independently of the main frame, an arm rigidly fastened at one end to the cross-head, in combination with double tightening rollers pivoted to the outer end of the arm and extending one above and one below the sprocket chain, for the purpose of keeping the same taut during the adjustment of the grain table. 6th. In a harvesting machine in which the trip is operated by pine or projections arranged on the surface of the rake wheel, an arm extending over the surface of the wheel and supported in such a manner that its distance from the surface can be adjusted. 7th. A havesting machine having a rolling rake head, a friction roller secured to the rake head by a bolt passing through an elongated hole or slot made through the internally projecting end of the rake head. 8th. A harvesting machine having a rear rake built on the grain delivery side of the table, the casting in one piece of the inclined guide forming one side of the throat, and the horizontal piece forming the other side.
