WHI-FFLETREE.
Specification of Letters Patent No. 5,221, dated August 7, 1847.
making, constructing, and using the same, reference being had to the accompanying.
drawing, making part of this specification, in which Figure 1 is an isometrical view of the front part of a carriage showing the mode of attaching the break and swingletree; and
detached.
The same letters indicate like parts in all the figures.
Several swingletrees have been made for detaching the horses by means of movable bolts and springs, the bolts being withdrawn by means of straps, chains, or other fixtures, but the difliculties heretofore unsurmounted have been, either that the apparatus had an unpleasant rattling from the arrangement of the parts, or the springs were necessarily made so weak that the traces were liable to be unhitched while traveling; or else it was found, when the springs were sufficiently strong, that it required so much force to withdraw the bolts as to renderthe fixture useless in practice.
To obviate the above enumerated difliculties, I construct my swingletree of iron or other suitable material of common form with a mortise (a) in each end; underneath the swingletree two springs (b) are aiiixed at points (a) and extend out to the ends of the swingletree; a bolt'(d) is attached to each of these springs that extends. up
through the mortise (a) as clearly shown in I Fig. 2: the end of the spring is turned down and has an eye formed in it into which a lever (e) hooks, said lever having its fulcrum at (f) by which it is attached to the swingletree; to the innerend of the lever (e) a strap is connected that ,extends up through a mortise in the swingletree and thence up to the carriage when it can be drawn by the hand of the driver at pleasure, which, by
means of this lever (e) has a great purchase on thespring to draw the bolt and by reason of which a very stiff spring can be'us'ed. This lever (e)is also found a great convenience inhitching .or unhitching the horse,
for by bearing on it with the hand'it draws down the spring, and with it the boltis withdrawn from the mortise as is represented at the end of the swingletree in Fig. 2.
What I claim as my invention and desire to secure by Letters Patent is- The combination of the lever (e) with the spring bolt for attaching the traces to the swingletree and detaching them therefrom, substantially in the manner and forthepur-y poseset forth.
