DRAFT HITCH.

Application filed January 8, 1927. Serial No. 159,870.

panying drawings wherein: I Figure 1 is a top plan view of a hitch constructed in accordance with my 1nvention' llih'. 2 is an elevation thereof, the frame being in sect-ion; I j Fig. 3 is a section on the line 3-3 of Figure 1.'

Referring to these drawings designates thetongue of a binder and B aportion of the frame thereof. My improved hitch comin'ises a plate 10 which is clamped upon the frame element B by means of bolts 11 or any other suitable means Pivotedto this plate 10 which projects forward beyond the frame beam B, is a link 12. The plate 10 is formed with a plurality of apertures 13 and a bolt 14: passes through the rear end of the link and througlrthe desired aperture and also passes through a slmrtiron 15 forming part of and bolted to the link 12. The forward end of the link 12 is pivoted toa brace 16 which is an approximatelyU-shaped strip of iii-etal, the inner ends of which are spread apart so as to embracethe tongue A. Thls brace 16 attached to the tongue by means of the bet 1?. The link 12 is pivotally connected to this brace by means of the bolt 18, the brace being formed with a plurality of apertures 19 through any one of which the bolt 18 may pass. Also pivoted to the boltlS is a link 20 which extends over the tongue diagonallythereto, and is pivoted to alever 21 by a bolt 22. This lever is pivoted to the tongue. by a bolt 23. The lever 21 is formed of a-n approximately U-shapedstrip of iron or steel and the 11111120 is received between the upper and lower thicknesses of the metal. The free end of the lever 21 is perforated for engagement by a clevis or other draft device. I

It will be seen that the parts 12 and 20 Y coi'istitute draw bars whereby the draft is carried back to the frame of the macl'iine. This device is particularly adapted to take the side draft off of a binder and. takes the draft from thetongue and carries it baclc to the frame. WVhile it is particularly adaptit} ed for a McCormick binder, it is not limited to this use asit may be used on all binders of the same general type or-on machines of the same general character, such as harvesters. p

It is pointed out that the clamp 10 can be adjusted in or out on the reamer sons to put the draft in the proper place and take draft away from the tongue and transmit itto the frame so as to equalize the draft. The arms 16 and 21 are pivoted upon the tongue and thus there will be no draft on the tongue whatever. An equalizer or evener will, of course, be. applied tov the member 21 by the usual clevis. It will be understood that I have illustrated the tongue and a portion of the frame diagrammaticat ly and that the parts A and B are intended to'represent or typify the usual tongue and frame'for. a harvester.

i I claim V In combination with a binder having a frame and a draft tongue disposed at a right angle to the frame. a plate mounted upon the frame beyond one side edge of the tongue, braces spaced from each, other and' from the plate and pivotally mounted upon the tongue, vsaid braces being disposed one beyond one side edge of the tongue and the other beyond the opposite side edge thereof, that brace which is adjacent the plate being disposed. beyond the same side edge of the tongue. a link pivotally connecting; the plate with the free end of the adjacent brace anda'link pivotally connecting the free end portions of both of the braces together and disposed obliquely across the tongue.

In testimony whereof I hereunto aflix my signature.

JAMES M. REES.
