WHIFFLETREE.
SPECIFICATION forming part of Letters Patent N 0. 550,877, datedDecember 3, 1895. Application and a... 27,1895. Serial No. 554,178. on model.)
To aZZ whom it may concern: 7
Be it known that we, WILLIAM A. J. GILES, residing at Concord, in the county of Merrimac, and GEORGE E. N. Dow, residing at Manchester, in the county of I-Iillsborough, State of New Hampshirepitizens of the United States, have invented certain new and use ful Improvements in I'Vhiffletrees; and we 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 appertains to make and use the same.
Our invention relates to improvements in whiflietrees in which the traces are secured to springs secured to the outer ends of the tree for the purpose of relieving the traces of any ar.
The invention consists in the means for securing the springs in place and a casing for protecting the springs and for guiding the same in their movements.
In the drawings forminga part of this specification, Figure 1 represents a plan view of one end of our whiffletree, the construction of both ends being the same. Fig. 2 is a horii Fig. 3 is a zontal section through the same. detail showing the spring.
Like reference-numerals indicate like parts in the views.
The whiffletree 1 is secured to the buggy by means of a bolt in the usual manner. Its outer ends 3 are tapered and flattened upon one side, as shown at i. Surrounding each of the tapering ends 3 of the whifiletree is a cone-shaped sleeve 5, which fits tightly there on, leaving a space at its inner end between it and the flattened portion 4: of the whiffletree. Formed integrally with the sleeve 5 or secured thereto in any suitable manner is an angular-shaped casing 6, which has an opening 7 at its inner end leading to the sleeve 5. Within the casing 6, projecting through the opening 7 and lying in the space left between the flattened portion 4. of the whiffletree and the inside of said sleeve 5, is a bar 8, of spring metal, which is bent from the direction in which draft is applied and rests normally in a position along the rear 5 the said springs are further protected ansHi guided by the angular-shaped casing 6.
Having thus described the invention, what is claimed as new is-- Thecombination with a whiffietree having tapered outer ends, of a cone-shaped sleeve fitting each end of said whiflietree, an angular casing integral with or secured to said sleeve having an opening thereinto at its inner end and a bent bar of spring metal fitting said casing projecting through said opening and secured to the whiffletree by bolts passing through said sleeve, bar and tree, substantially as and for the purpose described.
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
