Specification of Letters Patent.

Application filed April 23, 1908. Serial No. 428,752.

To all 'whom it may concern.'

Beit known that we, ALBERT C. DANN and RALPH L. FORD, citizens of the United States, residing at Bell and State of Ohio, have invented certain new and useful Improvements in Tongue- Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to tongue trucks for agricultural implements.

The object of the same is to provide a tongue truck which will exert a natural draft upon the implement, such as will neither tend to elevate the end of the stub tongue, by means of which the truck is connected to the implement, and thus throw the weight of the truck upon the draft animals, nor tend to depress the end of the stub tongue and cause unnecessary friction between the ground wheels and the ground; to provide such a truck which will accommodate itself to irregularities in the surface of the ground without exerting a strain on the stub tongue or causing the implement to tilt or turn; whichlwill be provided with means for connecting a tongue thereto, which means will be adjustable to support said tongue either in position for use with a four horse evener or in position for use with a three horse evener and will, at all times, support said tongue in a substantially horizontal position; and further, to provideV such a tongue truck which will be strong and durable, simple in its construction and capable of being manufactured at a low cost.

With these objects in view our invention consists in certain novel features of construction and in certain parts and combinations hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of our invention applied to a disk harrow of ordinary construction; Fig. 2 is a front elevation of the truck; and Fig. 3 is a longitudinal, sectional view, taken vertically of the truck. l

In these drawings, we have illustrated the preferred form of our invention and have shown the same in connection with a disk harrow 1, of Ordinar r construction, which is provided with the usual stub tongue 2, tothe outer end of which is connected the tongue truck. The truck itself preferably consists of an axle 3 having mounted thereon ground evue, in the county of HuronV Wheels 4 and a frame or standard 5 having its lower end connected to said axle 3. This frame or standard may be of any suitable construction andlmay be connected to the axle in any suitable manner, but, in the present instance, I have shown the standard as comprising a verticalbar having its upper end bent at substantially right angles thereto, as shown at 6, and extending substantially parallel with the axle .3. The lower end ,of the standard 5 is preferably pivotally connected to the axle in order to allow the axle to move about its horizontal pivot and thereby permit the wheels to accommodate themselves to irregularities in the surface of the ground. This pivotal connection may be formed in any desired manner, but we prefer to provide the axle with a casing 7 having its central portion slightly raised, as shown at 8, and provided with a suitable bearing block 9, which, in the present instance, is in the form of a disk arranged longitudinally of the axle and having the greater portion of its diameter extending above the casing 7 of the axle 3. The lower end of the standard 5 is provided with a suitable bearing adapted to ene gage the bearing block 9, and, in the present instance, comprising substantially circular bearing plates 10 of a diameter substantially equal to the diameter of the bearing block 9, adapted to engage the opposite sides thereof and secured thereto by a bolt 11 extending through the central portion of said plates and said bearin block, thus forming a pivotal connection between the plates and the bearing block which will permit of a free rotary movement of the plates relatively to the block and hold the same against movement in all other directions relatively thereto. The rotary movement of the bearin plates 10 relatively to the bearing block is llmitedby a suitable stop which preferably consists of inwardly extending flanges l2 ,formed on the upper portion of the plates 10 and extending downwardly along the circumference thereof to points sufliciently above the axle casing 7 to allow the axle the desired amount of pivotal movement. In addition to forming a stop to limit the movement of the axle relatively to the bearing and the standard 5, to which said bearing is secured,rthe flanges 12 serve to close the upper part of the bearing and prevent the entrance of dirt thereto. l

The bearing plates 10 are preferably secured to the standard 5 by providing the same with llO upwardly extending grooved arms or necks 13 adapted to engage the opposite sides of the standard 5 and to be secured thereto by suitable bolts le extending through the said upwardly extending portions and through the standard. rihe stub tongue 2 of the harrow is secured to the standard at a point above i the bearing plates l() and is preferably pivot l preferably formed in two parts, as shown, to enable a cotter pin 26 to be inserted in the bent-over portion 6 between the two portions of the bearing to hold the same against movement longitudinally of said bent-over portion. lilith this tongue plate connected to the standard in the manner shown in Fig. l, i. e., with the tongue plate ally connected thereto to enable the truck to proper in substantial alinement with the be turned about a vertical axis to guide the stub tongue, the tongue is in position to implement. accommodate the same to either a two or a In the preferred form of the device, the four horse draft evener. By reversing the forward end of the stub tongue 2 is rigidly position of the bearing 25 on the bent-over secured to a tongue plate 15, which, in turn, l portion 6 of the standard, the bearing plate is pivotally connected to the standard 5 by proper 23 will be supported at one side of means of a bearing sleeve l5 carried by tl e and some distance from the stub tongue 2, forward portion thereof and journaled upon thus accommodating the same for use with the standard 5, which, in the present ina three horse draft evener. stance, is circular in cross section. From the foregoing description it will be A suitable draft hitch is coupled to the apparent that we have provided a tongue standard 5 at a point near its point of conl truck of such a construction that the draft nection with said stub tongue. As here will be exerted upon the implement in a shown, this draft hitch comprises a vertidirect line, thereby avoiding any tendency cally arranged and forwardly extending 1 to either lift the end ofthe stub tongue, and, plate 17 having at its upper and lower edges consequently, the truck to which it is sesuitable collars 18 adapted to extend about l cured, thus exerting an unnecessary pull the standard 5 above and below the collar i6 I of the stub-tongue-connecting means and to i be rigidly secured to said standard by means l of bolts i9. The forward edge of the plate l l17 is provided with a vertically arranged l, series of apertures 20 adapted to receive a bolt 2l by means of which a clevis 22 is seupon the necks of the draft animals, or to exert a downward pressure upon the truck on the end of the stub tongue and truck, thereby causing an unnecessary amount of friction between the wheels of the truck and the ground g that the truck, by reason ofthe pivotal connection of the axle to the standard, is capable of accommodating support the draft evener. The draft hitch itself to any irregularities in the surface of being rigidly secured to the standard 5 and the ground without affecting the position the stub tongue 2 being pivotally connected of the standard or implement` connected thereto, it will be apparent that the standthereto. This pivotal movement being a ard and the axle which is connected thereto limited one about a horizontal axis and the and held against rotary movement about a l axle having no rotary movement relatively vertical axis relatively thereto, can be moved l to the standard, it will be apparent that` the by the operation of said draft hitch to guide truck is, at all times, under control through the implement in the desired direction, the the medium of the draft hitch which is y rigidly secured to the standard. Further,

movement of the standard relatively to the stub tongue being limited by suitable stops i it will be apparent that, by means of the reversible tongue plate detachably secured 27 formed on the opposite sides of the bearing sleeve 16 of the stub-tongue-connecting l to the bent-over portion of the standard, l the tongue can be supported in a position means, These stops are so'airanged as to l for use with either a four horse evener or a check the rotary movement of the truck before the same has been turned far enough three horse evener and that, when supported to bring the eveners into contact with the l in either position, it rwill extend in a sub implement. Suitable means are also pro- 1 stantially horizontal plane from its point vided for connecting a tongue to the standof connection to the standard to the neckard 5 at a point above the draft hitch in yoke carried by the draft animals; and such a manner that said tongue may be I further, that the construction of the truck adjusted to accommodate the saine for use is of a strong, durable nature, its parts few 3 in number and not such as are liable to bewith either a three horse or a four horse evener. ln the preferred form of the device, come dissarraiiged or inoperative, and, consequently, the operation of the device is this means comprises a reversible tongue plate 23 extending longitudinally to and simple and the cost of production is low.

N e wish it to be understood that we do substantially parallel with the stub tongue 2 and provided with a laterally extending not desire to be limited to the exact detallal of construction shown and described, for
