IMPROVEMENT IN WHIFFLETREES.
Specification forming part of Letters Patent No. 192,662, dated July 3, 1877; application filed May 16, 1877.
' which is placed above and the other below the pole, and the single-trees are placed between the upper and lower parts of the double-tree, ..-d are attached thereto by means of pivotpins, which pass through these parts and hold them together.
By this arrangement the whole of the parts of the whiffletrees'are held firmly and evenly in their proper horizontal planes, and not permitted to tip and twist out of place, as is common when the single-trees and doubletrees are connected together by means of hooks, rings, clevises, &c., as they usually are.
The double-tree is formed of two fiat pieces, such as any farmer can easily procure or manul'acture.
The invention will be easily understood by reference to the accompanying drawings, of which- Figure 1 is a plan of a pair of the improved whiffletrees, with a wagon-tongue, to which they are attached. Fig. 2 is a front elevation of the same.
The doubletree is formed of two pieces, A and A, one of which is placed above and the other below the pole B, to which they are coupled by means of the bolt or pin a, which passes through A, A, and B. This bolt should have ahead on its upper end and a not on its lower end, so as to hold the parts securely together. Between the outer ends of the pieces A and A are placed the sin gle-trees D, which are attached to the double-tree by means of the bolts d d that pass through both of the parts A and A and D, and hold them socurely together.
The bolts a and 01 should be round, so as to allow a free forward and backward play of the parts. The bolts d have two seats, 01 and d, in the outer ends of the double-tree, and slots (2 connect these two seats together, while I springs E close the said slots against the passage of the bolts 12, except when force is used to press the bolt d from one to the other of the said seats (1 0r 0?.
By this arrangement either of the singletrees may be moved farther or less far toward the end of the double-tree, at pleasure, so as to equalize the draft when horses of unequal strength are working together, or both singletrees may be placed farthest from or nearest to the center-pin a, so as to drive the team
