Patented Dec. 25, 1906.
Application filed April 27,1906. Serial No. 313.997.
To a/ZIZ whom it may concern:
Be it known that I, MICHAEL E. SHAW, a citizen of the United States, residing at Maplewood, in the county of Shelby and State provements in Vehicle-Tongues., of which the following is a specification.
This invention relates to a vehicle-tongue,
and more particularly one for a threshingmachine or the like.
The object of the invention is to provide a tongue which can be adjusted laterally to extend at diiferent angles to the axle for the purpose of properly guiding the machine when drawn by a traction-engine.
In the accom anying drawings, Figure 1 is a plan view of tlie invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1.
Referring specifically tothe drawings, 5 denotes the tongue, it being in two pieces 6 and 7, respectively, which are spaced vertically and pivotally connected, as at 8,to the brace 9, whereby the tongue is coupled to the of the tongue are two parallel cross-bars l() and 11, respectively, which are fastened at their ends to the brace 9 and extend between the pieces 6 and 7. The cross-bars serve as a guide for a block 12, having a horizontallyextending threaded hole 13 in which a screw 14 works. The screw is mounted in suitable bearings 15 on the brace 9 in such a manner that itis free to turn, but is held against longitudinal movement. By reason of this the block 12 will travel on the screw when the latter is turned, a hand-crank 16 being provided for this pur ose. f
At the butt-en of the tongue the parts 6 and 7 are slotted, as at 17 and 18, respectively, which slots register. The block 12 has a vertical opening in which a bolt 19 is carried, one end of which extends through At the butt-end the slot 17 and the other end through the slot 18, the former end being threaded, on which a crank-nut 2() is screwed. This conv nection between the block 12 and the tongue of Ohio, have invented new and useful Imcauses the tongue to swing around on its pivot 8, so as to extend at different angles to the axle when the block is made to travel on the screw. The tongue will be securely located in adjusted position, as the block cannot move until they screw is turned.
With a tongue constructed and o erating as herein described a threshing-machine can be guided to follow the tracks of the tractionengine when rounding corners, making short turns in crooked roads, or making a setting among stacks that are'set crooked, and the machine can be backed as readily as drawn forwardly.
I claiml. The combination with a support, of a tongue pivoted thereto, the butt-end of the tongue being slotted, a non-traveling screw, and a nut traveling on the screw and carrying a projecting member extendinginto the aforesaid slot.
2. The combination with a support, of a tongue pivoted thereto, said tongue comprising vertically-spaced bars, the butt-end of said bars having registering slots, cross-.bars extending between the butt-ends of the bars and Jfastened to the support, a non-traveling screw between the cross-bars, a nut traveling j on the screw, and a projecting member carried by the nut and extending through the aforesaid slots.
In testimony whereof I Ahave signed my name to this speciiication in the presence of two subscribing witnesses.
