To all lwhom t may concern: v

Be it known that I, HARVEY L. HOPKINS, a citizen of the United States, and a resident of Chicago, in the county .o-f Cook and State of Illinois, have invented certain new and useful Improvements in Mowing-Machines, of which the .following is a full, clear, and exact specification.

My invention is concerned with mowing machines, more especially of the rule-joint or vertical-lift type, in which the finger bar is pivoted to the main frame, or some connected portion thereof, at the shoe, so'that the finger bar can be raised to a vertical position, or substantially so, for transporting the machine; and it is designed to improve said machines by transferring apart of the weight of the cutting apparatus from the ground to the main axle when the team is pulling the machine, thus lightening the draft by lessening the effective weight of the cutting apparatus on the ground as it is dragged thereover, and improving the traction by throwing a part of the-weight of the cuttingapparatus o-n the driving wheels. My invention further contemplates utilizing the draft connections to the cutting apparatus as` a medium whereby any desired portion of the weight of the pole .may be carried by the draft. It also contemplates an arrangement of the draft connections whereby the whiifletrees may rise Figure l is a. sectional -view in side clef vation; and

Fig. 2 is a v detail of a portion of the machine as seen 'from the rear of the gag lever and the finger bar. n

The draft wheels 10 are journaled upon the axle 11, upon which is mounted the frame 12 in any customary manner, and the tongue 13 may also be connected with said bar 16 is pivoted tothe yoke 17, which in turn is pivoted on theend 18 of the coupling frame (provided the coupling-frame typo of machine is employed) in the customary manner, and the tiltinglever 19 may be connected by a. link 20 with the arm 21 of said yoke to vary the angle at which the shoe 15 is presented to the ground over which it travels. The lifting lever 22 is pivoted at 23 upon the main frame or a casting carried by the tongue, and is connected by a link 24C with the inner end of the gag lever 25, which is pivoted at 26 to the horizontal bearing 27 of the yoke 17, so that the outer end of thegag lever 25, coperating with a lug 28 extending upwardly and inwardly from the shoe l5, serves to swing the outer end of the finger bar 16 upward when the lifting leveri'22 is pulled back in the customary manner. All the construction heretofore described may beV of the ordinary type, and I have here illustrated the ordinary McCormick construction.

Pivotally mounted upon the bolt 29, or some other suitable projection extending from the side of the tongue 13, is a clevis yoke member 30, which has a yoke 31 for the whifle't'rees, and an elongatedvertical slot 32, through which the bolt 29 passes, so that the said clevis yoke 30 is free to rise and fall in order to keep itself in alinement with the draft connections and the points on the breasts of the horses where the draft comes. An arm 33 extending rearwardly and to one side of the 4clevisyoke 30 coperates. with the under side of the tongue 13 fto limitI the rearward position to which the yoke, a pulley mounted on the gag lever, a In Witness whereof, I have hereunto set helically-coiled contractile spring connected my hand and affixed my seal, this 21st day at one end to the elevis yoke, and a chain 0f February, A. D. 1914.

connecting the other end of the spring and HARVEY L. HOPKINS. [1.. s.] the main frame beneath the aXle and pass- Witnesses:

ing beneath the pulley, substantially as and JOHN HOWARD MGELROY,

for the purpose described. MILDRED ELSNER.
