Specification of Letters Patent.
Patented Mar. 14, 1922.
Application filed February l2, 1921. Serial No. 44E-4,549.
To all whom t may concern.'
Be it known that I, JAMES E. Hanni', Jr., a citizen of the United States, residing at Louisville, in the county of Jefferson and State or' Kentucky, have invented certain new and useful Improvements in IYhilietrees, ot which the following is a specification.
This invention relates to improvements in whiiiletrees, it relating more particularly to the construction of the individual parts ot such devices, such as single-trees, doubletrees, treble-trees, evener-bars and the like, being also applicable to such d evices as pole yokes, implement hitchcs, etc.
The object of the invention is to provide a structure which will be economical in manufacture and at the same time of gre-at strength and durability.
A more specific object oi the invention is to provide a structure of the character referred to which Will embody a central metallic core or body reinforced by Wooden side strips, together with the trace hooks, center loops or eyes, or other attaching devices, so arranged that the attaching devices are connected directly With the center metallic core to furnish a more secure fastening :for such devices, and eliminate other disadvantages incident to connecting the devices to the Wood.
In the accompanying drawings:
Fig. 1 is a top plan view oi' a Whiilletree part, in this case a single-tree.
F 2 `is a side vieu7 of: the same.
Fig. 3 is a longitudinal section ou the line 3 3 of Fig. 1.
In the construction of devices of this character, it has been common to make them of Wood and also of metal. When constructed oi Wood, the trees are liable to breakage and the attaching eyes and hooks become loose as the wood shrinks, and when constructed of metal they must be made 'light enough to compete with the Wooden trees, as a result Vof which. the trees bend easily and are then diiiicult to straighten. Some attempts have also been made to construct such devices of Wood and metal, but all structures of this character With which the applicant is familiar have all of the disadvantages of the Wooden trees in the manner of' securing trace hooks and other attaching devices thereto, in that the devices are connected to the Wood and thereby become loose when the wood shrinks.
Referring to the drawings, 1 represents a strip or bar of metal, preferably steel, to the respective sides of which are secured, by rivets 4, strips or bars of Wood, 2 and The Wooden bars are shorter than the metallic bar so as to leave the ends of the metallic bar exposed, as indicated at 1a. To these extended ends 1a ot the metallic bar are pivotally attached, by rivets 6, the vokeshaped parts 5 of trace hooks 5. Attached to the center ot the tree thus formed, by a rivet 8 which passes through the respective bars of Wood and steel, is the yoke-shaped part 7a of a loop or eye 7 by which the single-tree is attached to the double-tree of other part of the Whii'lietree.
By the construction described it will be seen that a tree is provided which is economical iu manufact-ure and strong and durable in character, and also one in which the attaching hooks and eyes are secured in a manner to bring the strain of drait directly upon the steel core, the hooks being attached solely to this core in a Way Which will not only obviate the disadvantages incident to the shrinkage of the Wood but also which Will eliminate the use of the usual ferrules employed for the purpose or other more expensive manners of connection.
Having thus described my invention, I claim In a. structure of the character described. a laminated tree consisting of a central me-l tallic bar and Wooden bars or strips above andbelow said central metallic bar, means for securing said bars together, the central metallic bar having end extensions that project beyond the laminated part of the structure, thereby forming an integral single supporting member extending from a point beyond one end of the structure to a point beyond the other end of the structure, 'and attaching devices so arranged that one device Will be attached to each end extension and lie adjacent the end ot the laminated structure.
In testimony whereof, I have hereuntol set my hand this 7th day of February, 1921.
JAMES- E. HAR-DY, JR.
