WHIFFLETRE'E-IRONS.

SPECIFICATION forming part of Letters Patent No. 255,705, dated March 28, 1882. Application filed January 20, 1832. (Model.)

To all whom it may concern:

Be it known that I, OLIVER VANORMAN, of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Irons for Single and Double Trees; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the'a'ecompanying drawings, which form part of this specification.

'My invention relates to an iug provemeut in single and double treeirons; and it consists in the combination of a casting, which is made E-shaped, so as to fit over the top and under thebottoni of the double-tree, and which has a curved prong which extends up over the top of the single-tree for thebolt to pass through, and is also provided with a circular flange around the bolt-hole, on the partwhich rests upon the top of the'doublc-tree, with the casting which fits under and on top of the singletree, and which passes up over the front side, so as to support the tree atthis point, anda single-bolt, which passes down throughthe castings and the single and the double trees,

as will be more fully described hereinafter.

Theobject of my invention is to so construct the irons-as to give the full strength of the woodland support and brace them at those points where there would be a. tendency to break, and to do away with all screws which have heretofore been used for fastening the irons in position, and which have only a tendency to split the wood, besides making the irons more expensive. I

Figure l is a detached view of the two parts, showing them ready to be put together. Fig. 2 is a vertical cross-section taken through the two trees and the casting that secures them together.

A represents the double-tree and B the single-tree. which are of the ordinary construction. To the double-tree-is applied the casting 0, which is made E-shaped, as shown in Fig. 1, so that its lower portion willpass under the lower side of the double-tree, and the por The upper portion, G, of this casting (J is curved slightly backward and forward, so as to extendup over the top of the single-tree. Upon the top of the plate or extension F is formed the circular flange I around the bolthole, and this flange is about the same thickness as the lower part of the casting H. This circular flange forms a pivot around which the casting turns, and does away with all necessity for screws or other fastenin gs for securing the castings H. in position. This casting H consists of 'the wide flat plate 0, which extends under the bottom of the single tree, and the curved part 1?, which extends up over its top. This casting is applied to the front side of the single-tree, and serves asa brace to the tree just at that point where the strain is brought to bear upon it. After the two castings are 7 applied to the two trees, as here shown, a single bolt, Q, is passed down through the two castings and the two trees, and then'is secured in position by means of anut or other suitable device for fastening it.

It will be seen from the above construction that the whole strength of the wood is re tained, that there are no screws used for fastcning the different parts in place, and. that the single-tree is braced and strengthened at the point where it is most needed.

Having thus described my invention, I claim-- 1. The combination, with the single and double trees, of the two castings 0 and H and the bolt Q, the parts being arranged to operate substantially as shown.

2. The combinatiop, with the single and double trees, of the casting 0, having the part D to catch under the double-tree, and the part F, provided with acircularflange, to catch upon its top, and the part G to extend up over the top of the whiffletree, with the casting H, which is held in position by the flange upon the part F, and the bolt Q, which passes down through all of the parts, substantially as set forth.

In testimony whereof I aflix my signature j Witnesses:
