'To all whom 'it may concern:

Be it known that I, JAMES M. ORPUT, of the town of Maltain the county of De Kalb and State of Illinois, have invented certain new and usefullmprovemen ts in Wagons; and I do l1ereby declare that the following is a full, clear, and exact )description thereof, refr erence being had to -the accompanying drawings,'and to the letters of reference marked thereon, which form a part of this specifica` tion.-

My invention relates to a novel mode of attaching a wagon-ton gue to the gear, in vconnection with the device or medium through which the draft is applied, whereby the tongue is rel lieved of all draft and becomes a guide merely, whereby the efficiency of the tongue as a guide is greatly increased, and whereby the draft is at all times applied to the extremities of the axle, or to either extremity that is at the time being retarded by an obstruction to the adjacent wheel.

' My invention consists, first, in locating the fixed fulcrum or rear attachment of the tongue at a point inadvanceof the forward axle,

which point has a permanent relation to the the extremities of the axle, and of shifting the,

draft mainly and directly to either Wheel that may be obstructed.

.Figure l is a perspective- View of a portion of a wagon gear embracing my invention. Fig. 2 is a top View of the same, showing the relative Vmovements of the tongue and forward axle with reference tothe remaining portion of the wagon, the direction of which remaining portion is represented by the central reach, B.

Fig. 3 shows apreferredform of the universal joint by whichfthe tongue is connected at'its stationary `or `fixed fulcrum.

A in the drawings indicates the forward axle of a wagon, pivoted Vby the bolt Kto the usual reach R. The reach is prolonged to form theforward'extension, R', to the extremity of which the tongue T is attached by the universal joint 0; S is a sleeve tted to slide freely'ppon the squared tongue, provided with the side ears, ay a, the hammer-strap h, and evencr-pin i.

B B are stiff rods, formed with eyes at both ends, and connecting the sleeveSto the axle Aby the ears a a. and the eyeboltsibhf The evencr being attached by the pin t" to the sleeve S, which is loose upon the tongue, it -is plain that the draft will be communicated through the rods B B directly to the axle at the points b b, and it is also plain that when either wheel is obstructed .the draft will be wholly or mainly diverted to the rod B, which is connected near the obstructed wheel.

The operation of my improved tongue to give more easy and prompt control over the movements of the axle is made plain by noting that the rear or short arm of the tongue, regarded as a lever, is lshorter than in an ordinary wagon, while the long arm remains the same, giving increased advantage or leverage to thepower applied to the long` arm for the control of the forward axle; or my device may be otherwise regarded as a/compound lever substituted in placeof a simple bent lever `of an ordinary wagon, in which `the entire tongue, from its free extremity to the kingbolt, is the long arm, and the axle, from the kingbolt K to the wheel, is the short arm.

That the compound lever so` substituted increases the advantage of the power applied at the free end of the tongue is proved by the fact that in my device said end'of the tongue moves through a greater arc in producing a given movement of the axle than does the Same point in an ordinary or rigidly-mounted tongue. This advantage is secured by liexibly connecting the rear extremity of *thetongue relation required with the rear or main portion of' the wagon.

Itis necessary in extending the reach for this purpose, as shown, that it be made stronger than usual against lateral strain at K, and that the connections at C be made strong and be firmly secured. The rods or bars B should also be heavy and rigid, as in turning the Wagon one bar serves as a strut, and must not bend or buckle.

The sleeve or slide S is preferably of the form shown; but it may consist of a narrow ring loosely fitted to the tongue, and either rigidly or exibly connected with the rods B B. The evener-pin iis preferably located in advance of the connections u a., ns shown.

In a wagon thus constructed not only may the forward axle be. more perfectly and promptly controlled through the tongue, but the tongue itself may, in the same proportion, and for the same reason, bc more steadily and more easily held by the neck-yoke or breaststraps. As an incident to the greater sweep ofthe tongue in turning the Wagon, the team and Wagon may be turned about in less space l than is r. quired by an ordinary wagon cramped To the same extent.

Itl would be the equivalent of the device shown and within my invention if the sleeve S be made fast to the tongue anda sliding hinge movement provided at C, and such device is intended to be embraced by my following claim.

Having thus described my invention, I clailu and desire to secure by Letters Patent- A Wagon-tongue, T, tiexibly connected at a point, C, located in advance of the point K, and held in permanent relation to the rear portion ot' the wagon, or to the reach R, in combination with the slide S and the rods B B, substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing as luy invention I atlix my signature in presence of two Witnesses. I

JAMES M. URPUT.
