DRAFT-COUPLING.
Specification of Letters Patent. Patgnted June 2,2, 1920.
Application led November 5 1918. Serial No. 261,264.
To all lwlw/m, it may concern.'
Be it known that I, lecon lV. BULLnn, a citizen of the United States, and a resident of Hillsboro, in the county of Marion and State of Kans s, have invented a new and lmproved Draft-Coupling, of which the following is a full, clear, and exact description.
Among the principal objects which the present invention has in view are: to provide means for automatically releasing a movable drawn member from power means for arresting the former; to prevent wrecking of a plow or similar apparatus when the progress thereof is arrested independently of the tractor means during the progress: and to simplify the construction and cheapen the cost thereof.
Drawings.
F 2 is a top view of the same; 191g. 3 is a vertical cross section of the coupler, thesection being taken as on the lline 3-3 in F 1g. 1.
Description.
As seen in the drawings, the coupler has a tongue 8, the upper section whereof hasl a hook 9, which is engaged by the toe 10 of a trigger 11. The tongue 8 is provided preferably with a swell 12, whichV forms a rest for the heel 13 of the said trigger. A second swell 14 serves as a rest for a bridge plate 15, which serves to prevent the rock ing of the trigger 11 to release the toe 10 thereof.
At the rear of the swell 14, is an apron 16, the perforations 17 in which serve to receive the retaining bolts 18 of the usual plow beam.
At the forward end of the tongue S, the top 19 is reduced to form a wedge-like member which is driven under the toe 1() of the trigger 11 when the tongue 8 is being installed in connection with the tongue retainer 20.
rfhe trigger 11 is pivotally mounted on a shaft 21 extended between the side bars of a jaw The jaw 23 is united at its free end by the bridge plate 15. The bridge plate 15 has end tabs perforated to pass the bolts 2st. and to be pressed by the springs 25 when the same are compressed by the nuts 26 and washers 27 disposed thereunder. The nuts 2G engage threaded sections of the bolts 24. rlhe jaw 23 is l'iivotally connected by the shaft 2S, with the retainer 20, and adjacent the yoke arms 29 thereof. The arms29 are suitably perforated to receive the link bolt 30, for holding the link 31, which is usually extended from a tractor or other suitable power device.
To form a recess for the tongue S, the retainer 2O has grooves formed therein by overhanging flanges 32.
From the foregoing it will be seesA that the draft strain imparted to the tongue 9 and retainer 20, is borne by the trigger 1l and the hook 9. lt will also be seen by reference to Fig. 1 of the drawings, the point of engagement f the trigger 11 and the toe 10 thereof with the hook 9, is below the center of the shaft 2l, on which the said trigger 11 pivots. s a result of this arrangement, the pulling strain tends to rotate the said trigger and to lift the jaw 23 with which the saine is connevted. rllhis action is resisted by the springs 25, whirh hearing upon the plate depress the jaw and the trigger 11 connected therewith until the heel 13 bears on the swell l2.
lWhen the draft strain beromes greater than the resistance afforded by the swings 25, the trigger 11 is rotated to a position where the tongue 8 and hook 9 thereof are drawn from engagement with the trigger and with the retainer. permitting the said retainer to be carried forward by the tractor while the trailer or other implement being drawn remains in arrested position.
l/Vhen the obstruction which has resulted in the extra resistance of the trailer has been removed and the tractor is returned for rengagement, this is readily aecomnlished by inserting the tongue 8 within the retainer 20, the wedge-shaped tip 19 being forced under the toe 10 of the trigger 11,
hook v9.

l; A draft coupler comprisinga plurality of separably Connected members adapted for engaging a power member and a load memfber, respectively; a trigger operatively uniting said members ivliendisposed in parallel arrangement; a swinging member' pivotally connected with one of said members and with sai-d trigger io-r supper-ting the latter; and yielding means for .dep-ressi-ng the lfree end of ysaid swinging member forholdine said trigger in operative rela- ',tionto said separable members, ,said yielding means embodying springs and guide bolts therefor, said .bolts .being mov-ably attached .to both or' said separable members.
