` CHRISTOPHER C. BAILEY, 0F CLINTON, MISSISSIPPI.

DOUBLETREE.

Application filed June 19, 1923-.

To all whom t may concern:

Be it known that I, CHRISTOPHER C. BAILEY, a citizen of the United States, residing at Clinton, in the county of Hinds and State of Mississippi, have invented cer tain new and useful Improvements in Doubletrees; and I do hereby declare the following to be a full, clear, and eXact desc-ription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to singletrees and more particularly to a doubletree adapted to hitch a team of horses by means of singletrees to the vehicle, implement or the like to be drawn, said doubletree being reinforced and involving a relatively simple and durable structure.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

1While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is a top plan view of a doubletree embodying the invention,

. Figure 2 is a detail sectional view of an end portion of the doubletree,

Figure 3 is a detail sectional view on the line 3-3 of Figure 1,

aFigure 4 is a detail sectional view showing the means whereby the clevis is attached to the doubletree, and

Figure 5 is an elevational view of the clevis.

Corresponding and like parts are refer'- red to in the followingl description and V designated in the several views of the drawings by like reference characters.

The numeral 1 designates the doubletree which is preferably constructed of wood and similarly tapered from a middle point towards opposite ends. Metal tips 2 are applied to opposite ends of the doubletree and straps 3 project therefrom and extend along the front and rear sides of the doubletree and terminate a short distance from the Serial No. 646,415.

center thereof. A metal strap 4 extends along the front side of the doubletree and overlaps the inner ends of the front straps 3 and is secured to the doubletree by means of fastenings 5 which also serve to connect opposite straps 3. The middle portion of the strap iron 4 is curved forwardly, as indicated at 6, and a plate 7 interposed between the strap 4 and the doubletree 1 has its middle portion 8 curved rearwardly, the oppositely curved portions 6 and 8 forming an opening to receive the clevis pin 9. Fastenings 10 connect the irons 4 and 7 to the doubletree 1. The clevis 11 embracing opposite sides of the doubletree is pivoted thereto by means of the pin 9 and receives a hook 1Q which is connected thereto by means of a swivel joint. The clevis 11 and hook 12 provide means for attaching the doubletree to the part to be drawn, such as a vehicle or agricultural implement.

A U-shaped strapy is secured to each end of the doubletree and comprises elements 13, 14 and 15, the elements 13 and 14 extending along opposite sides of the doubletree and the element 15 extending across the end thereof. A loop 16 is formed at the juncture of the elements 14 and 15 and receives a hook 17 by means of which a singletree, not shown, is adapted to be coupled to the doubletree. Fastenings 18 connect the parts 3, 13 and 14 to one another and to the doubletree. The several fastenings may consist of rivets or analogous means generally employed for securing the parts to be fastened.

`What is claimed is:

1. In a doubletree, a bearing iron applied to a side thereof, a reinforcing iron overlapping the bearing iron and side portions of the doubletree beyond the bearing iron, a clevis pin received between the bearing and reinforcingl iron which are oppositely curved to receive the same, and a clevis pivotally connected to the doubletree by means of the clevis pin and having a hook connected thereto by means of a swivel joint.

2. A doubletree, metal tips at the ends thereof. straps extending` from the metal tips and engaging opposite sides of the doubletree, a U-shaped iron applied to each end of the doubletree and having an outer loop in which is fitted a hook, bearing and reinforcing irons applied to the front side In testimony whereof I aix my signature of the doubletree, a clevis pin disposed bein presence of two witnesses.
