DRAFT APPLIANCE.

Application filed June 26, 1925. Serial No. 39,763.

To all whom it may concern:

Be it known that I, CLAUDE DAUGHERTY, a citizen of the United States, residing at Sinithville, in the county of Clay and State of Missouri, have invented certain new and useful Improvements in a Draft Appliance, of which the following is a specification.

The present invention relates to a draft appliance, and aims to provide a device for attachment to a wagon, cart, or like vehicle to which three horses are to be hitched, comlnonly termed a three up hitch. The device consists essentially of a rigid frame attached to the front axle of any type of vehicle. This frame carries a stub tongue on the center line of the vehicle, and has attached thereto a triple tree. In an oiiset position, a tongue is attached to the frame and is hingedly associated therewith so as to allow a free up and down motion, and at the same time transmit all side motion to the front axle. There are also provided parts for supporting the entire weight of the de vice from the body of the vehicle by means of two rigid side braces and one rigid center brace attached to the front axle, and one adjustable top center brace running from the top of the stub tongue back over and around the king pin, thereby relieving the king pin of all the weight of the device, and fastened into the body of the wagon on a fifth-wheel wagon or into the coupling pole of a farm truck. The side rigidity of the tongue is obtained by the employment of a curved brace running from the tongue to the stub tongue.

All present three up hitches have tongues rigidly connected to the frame work in front of the front axle; this frame work being hinged to the axle and partially supported by a tie to the top of the king pin, thus throwing a large amount of the weight of the device on the horses necks on level ground and allowing an excess of side play to the tongue. On a down hill pull, as over a bank, the tongue assumes a position in line with the ground upon which the wagon stands, thus placing the tongue in such a position as to render it very difficult for the team to control the course of the wagon. My improved device, by the employment of the braces mentioned, relieves the team of all the weight of the device, they carrying only the weight of the tongue At the same time the hinged tongue, which is braced into the stub tongue, gives the team complete control over the wagon on all kinds of road.

A further very important object of the present invention is to provide a device of this nature which is exceedingly simple in its construction, strong, durable, efficient and reliable in use, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the descrip tion proceeds, the invention resides in cer tain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a top plan view of the appliance embodying the features of my invention,

Figure 2 is a side elevation thereof,

Figure 3 is a vertical transverse section taken substantially on the line 33 of Figure 1,

Figure -l is a detail section taken substantially on the line dat of Figure l, and

Figure 5 is a detail horizontal section taken substantially on the line 5-5 of Figure 2.

Referring to the drawing in detail, it will be seen that the frame includes a pair of said braces 5 attached to a stub tongue 6, at one end and engaged at their other ends with a bolt '7 running longitudinally with and in front of the axle 8, and mounted thereon by means of suitable brackets 9. The frame also includes a bar 10 extending forwardly from the bolt 7, and provided with a right angularlyextending portion 11 at its forward end which is bent backwardly as is indicated at 12 so as to be attached to the stub tongue 6. It is to be noted that the bars 5 converge forwardly toward each other and therefore are disposed at acute angles to the bolt 7. The main tongue is indicated by the numeral 13 and is swingable in a vertical plane 011 a bolt 14 extending through the stub tongue 6, and laterally therefrom through the bar 10, said tongue 13 being disposed alongside of said bar 10. A rigid brace 16 is attached by suitable clamping means 17 to the axle 8 and extends forwardly and is fixed to the bolt 14 by a nut 17, or in any other suitable manner. A curved arm 18 is fixed at one end as at 19 to an intermediate portion of the tongue 13 forwardly of the frame and extends laterally and rearwardly from the tongue and is rotatably engaged on the bar 14 as at 20. A spacing sleeve 21 is disposed on the bolt 14 between bar 10 and the end 20 of arm 18. A brace 22 is engaged on the bolt 7, and is bent to extend at an acute angle therefrom inwardly and to be attached to the bolt 24 which passes through the bar 10, see Figure 5, through the bars 5, and stub tongue 6, by means of a nut 25. A spacing sleeve 26 is disposed about this bolt 2% between the bar 10 and the adjacent bar 5. A brace 27 is rigidly clamped as at 28 to the end of the axle 8 opposite to the clamping device 17, and extends forwardly and inwardly for attachment to the bolt 2% adjacent the brace 22 as is clearly illustrated in Figure 5. A bottom brace 29 extends from the bottom of the stub tongue 6, and is attached to the bottom of the axle 8.

An adjustable brace 30 is fixed to the bolt 31 extending through the stub tongue 6, and extends rearwardly, having a section 32 adjustably associated therewith and provided with a slot 33 for receiving the king bolt 34. Bolts 36 are attached to the section 33 and may be engaged into the body of the wagon on a fifth-wheel wagon or into the coupling pole of a farm truck, both structures being well known in the art, and therefore not illustrated in the accompanying drawing. This bracing feature relieves the king pin of all the weight of the device.

A triple tree structure 35 is engaged on the bolt 31 below the brace 30.

It is thoughtthat the construction, operation, and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed merely by way of example, and in practice attains all the features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that the numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

lilaving thus described the invention, what I claim as new and desire to secure by Letters Patent isz- 1. In combination with a vehicle front axle, a rigid frame attached thereto, a stub tongue carried by the frame, a bolt extending laterally from the stub tongue, a main tongue rotatable on the bolt and capable of swinging vertically, a curved arm attached at one end to an intermediate portion of the main tongue and extending therefrom rearwardly and laterally and pivot ally engaged with the bolt adjacent the stub tongue, a multiple draft tree attached to the stub tongue, a king pin rising from the axle, an adjustable brace engaged at its forward end to the stub tongue and extend ing rearwardly therefrom and having a slot for receiving the king pin, and means for attaching it to the body of a. wagon or the like.
