HITCH.

Application filed March 12, 1923, Serial No. 624,546. Renewed July 17, 1925.

To all whom z't may concern:

Be it known that I, JAMEs M. PERKINS,

a citizen of the United States, residing at Nest Bend, in the county of Palo Alto and State of Iowa, have invented new and useful Improvements in Hitches, of which the following is a specification.

The object of this invention is to produce a hitch for use as connecting means for rain binders arranged in gangs as well as for hitching the front binder to the tractor or other propelling means in a manner whereby the binders will be retained in proper staggered relation to each other, the tongue trucks of the binder will be caused to turn faster than the poles, making square turns possible and likewise causing the several binders to turn at the proper tlme, as well as relieving the propelling means and binders from undue strain incident to the turning of the binders.

To the attainment of the foregoing, and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a plan view of the hitch between a binder and the propelling means therefor.

Figure 12 is an enlarged top plan View more clearly illustrating the hitch.

Figure 13 is an elevation with parts in section, to illustrate the manner in which the hitch is attached to the tongue truck.

Figure lt is a fragmentary perspective view of parts of the improvement.

As my hitch may be employed as a connecting means between a single binder and the propelling means therefor and as the structure is slightly modified from that employed in connecting gangs of binders I have, in Figures 1 to 8 of the drawings, shown in detail a form of hitch construction especially designed for this purpose. In certain of these figures the forward portion of a grain binder is indicated by the numeral 1, the tongue 2 thereof having its outer end supported on a tongue truck 2 of the usual construction. The tongue truck has its frame provided with the usual standard that is revolubly received in a bearing bracket on the end of the tongue 2, and on the standard between the spaced projecting arms of the bracket there is pivotally mounted a bifurcated casting to which the draft pole 5 is ordinarily pivoted. In the present instance the pole is cut-away to provide a comparatively short block, and on the under face of this block there is secured a strap 6 that has one end provided with an eye 7 through whichpasses a pivot 8 that attaches the same to the casting. Arranged at one side of the block 5, in a line parallel therewith there is a bar and pivotally connecting the said bar, adjacent to the rear thereof to the rear of the block 5 thereis a cross strap or plate 10, the pivots being indicated in the drawings by the numeral 9. Pivotally secured to the rear end of the bar 4 and to one side of the pole 2 there is a rod 16, the latter preferably having a hooked outer end that is received in an opening 17 in the said end of the bar 4.

Pivotally secured, as at 10 to the forward end of the block 5, as at 11 there is a strap or plate 12, the same having adjacent to its free end a series of spaced openings 13, one of which designed to register with a series of openings 14 in the bar 1. There is passed through the aligning openings a pivot member 15, the same being preferably in the nature of a headed stud that has its shank slotted to receive therethrough removable retaining means such as a cotter pin. As a matter of fact, all of the pivots as well as the connecting means for the eye carrying strap 6 have their shanks slotted for the reception of cotter pins.

The bar 12 is arranged at an outward angle with respect to the block 5, and the outer or forward end'of the bar 4: is connected in the usual manner to the propelling means for the binder 1, the same in the present instance being in the nature of a tractor 3. V v

By reference to the diagrammatical view, Figure 3, it will be seen that when the tractor 3 makes a turn the same willpull directly on the bar t to cause the same to assume an outward angle with respect to the tongue 2, andlike wise cause the strap or plate 12 to exerta direct pull on the truck 2, causing the latter to turn more quickly than the tongue 2, and consequently permit of the binder making a short square turn without undue strain thereon or on the tractor.

The hitch employed for connecting a gang of tractors is only slightly different from the construction above set forth and has been illustrated in the remaining figures of the drawings. While I have in Figure 9 shown only two binders connected in accordance with my improvement it is, of course, obvious that any desired number of these machines may be arranged to the rear and to one side of each other. The binders 1 are provided centrally to the rear of their cutters with coupling means 18 to which there are pivotally connected bars 19 similar to the bar 4. The tongue 20 of each binder is mounted on the tongue truck 21, the bifurcated casting 22 which is arranged between the parallel arms of the bracket 23 secured to the forward end of the tongue and through which the standard of the truck frame passes haspivotally connected thereto the eye of astrap that is secured to a block 24 similar to the block 5. The forward end of the block has pivoted thereto a bar or strap 25 similar to the strap 12, the same being adjustably connected to the bar 19 in a manner similar to the connection of the strap 12 with the bar 4. The bar 19 terminates a slight distance to the rear of its pivotal connection with the strap 25, and there is pivotally secured, as at 26 to the said end of the bar 19, one arm of an angle member 27. The second end of the angle member is pivotally connected, as at 26 to the rear of the block 24. Between the angle arms ofthe member 27 there is a brace 28, and pivotally connected to the rear arm of the angle member 27 there is a rod 29 which is likewise pivoted to one side of the tongue 20.

By reference to the diagram shown in Figure 10 of the drawings it will be seen that when the forward binder 1 is turned the pivotal connection between the coupling 18 and the bar 19 will be first broken and thereafter a direct pull will be exerted between the coupling and the bar. This causes a direct pull to be exerted upon the strap 25 and as the rod 19 is swung on its pivotal connection with the strap 25 until these elements are almost in a line the truck 21 will be turned to a determined angle before the tongue 20 is caused to turn. The elements 27 and 29 materially brace the tongue and materially assist the turning of the several binders at the proper point in which said turning should occur so that the cutters of all of the binders will be arranged to the rear but at the sides of each other.

A hitch constructed as above described may be easily produced, cheaply manufactured and easily installed without the employment of skilled labor. The advantages of the improvement will, it is thought, be apparent to those skilled in the art to which this invention relates, but I do not desire it understood that I am to be restricted to the precise structural details herein set forth as I hold myself entitled to all such changes therefrom as fall within the scope of my claims without departing from the spirit of the invention.

Having described the invention, I claim 1. The combination with a binder having a truck supporting the tongue thereof and a tractor for propelling the binder, of a hitch comprising a bar loosely connected to the pole and tractor, a block disposed to one side of the bar, a plate secured thereon having an eye end, flexible means passing through the eye for connecting the block to the axle of the truck, transverse plates pivotally connecting the inner ends of the bar and block, a plate pivotally secured to the outer end of the block and disposed angularly over the bar, said plate having spaced apertures and said bar having a single aperture with which one of the first mentioned apertures is designed to align, and securing means passing through the aligning apertures.

2. A hitch for connecting binders arranged in gangs and for connecting the propelling means for the foremost binder, comprising each a block pivotally supported on the standard of the binder tongue trucks, a bar arranged to one side of the block each connected to the leading binders and to the propelling means, means pivotally connecting the rear of the bar with the rear of the block, a brace rod arranged angularly of and pivotally secured to the outer rear end of the hitch and one side of the tongue, and a strap plate pivotally secured to the outer end of the block, disposed at an outward an- Igle therefrom and adjustably pivoted to the 3. A hitch for binders arranged in gangs and for the propelling means for the binders, each comprising a block pivotally connected for vertical swinging to the tongue truck frames of the binders, a bar of a greater length than the block arranged to one side thereof, and said bar being respectively pivotally connected to the adjacent binders and to the propelling means for the binders, said bar having spaced apertures therethrough, a strap plate pivoted to the for ward end of the block having adjacent its outer end spaced apertures, a removable pivot passing through one of the aligning apertures in the strap and in the bar means pivotally connecting the rear end of the bar to the rear of the block, and a brace rod pivotally connected to one side of each of the trucks, arranged at an outward angle therefrom and pivotally connected to the rear of the hitch.

In testimony whereof I aflix my signature.

JAMES M. PERKINS.
