IMPROVEMENT IN DRAUGHT-ATTACHMENT.

(1th gtlgrmzlr harm in in the: inter fitment animating gut in its arms.

To ALL WHOMIT MAY CONCERN:

Be it known that I, MOSES ADSIT, of Forrest, in the county of Clinton, and State of New'Yor-k, have invented a new and improved Draught-Attachment for vehicles; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference-being had to the accompanying drawings, forming part of this specification. I i

This invention relates'to a new and useful improvement in draught-attachments for all kinds of vehicles which are drawn by horses, and has for its object the equalizing of the draught, by admitting of the whifile-trees being automatically adjusted in relation with the double-tree under pull of the team, and in such a manner that if one horse of a team has an inclination to pull more than his share, his labor will be proportionably increased, while the other horse will have'his labor correspondingly decreased, and will feel encouraged to exert himself 'and pull up even with the more ambitious one. 7

By this means} the device will not only have a tendency-to correct a team which pulls unevenly for the time edge of the same, as shown in fig. 2.

being, but will also have a tendency to break or train an unmatched team, so that the two horses of the same will in a short time be permanently matched, so far as equal draught is concerned. In the accompanying sheet of drawings w m Figure 1 is a plan or top view of my invention. Figure 2, a section of the same taken in the line at a, fig. 1. Similar-letters of reference indicate corresponding parts. A. represents a draught-pole, which does not require any peculiarity in its construction, and B is a doubletree, secured to the draught-pole by belt, a, which passes through the front end of a metal strap, 0, the rear part of which is bolted ,to the draught-pole, andis bent upward, so as to extend over the double-tree, to the front This double-tree'is constructed 'ina peculiar manner as follows: To thercar side of the same there is attached a metal bar, D, the ends of which are hent'around the ends of the double-tree, and firmly bolted thereto, agroove or rebate being made in the upper and lower surfaces of the double-tree to receive plates 6 6, which are somewhat shoiter than the double-tree, in order that the latter'may have a certain degree of longitudinal play independently of them.

To the ends of these platesb b clevises E E are attached, the 'boltsc of which pass down through oblong slots, (2, in the whifile-tree, to admit of the independent play of the-double-tree, and at the same time allowing said bolts to connect the two plates. The whiihc-trees to which the horses are attached are connected to these clevises.

The strap C has abolt, a, passing through it, which extends through anoblong slot,'f, in the double-tree,

and also through the two plates 6 b and into the draught-poleA, (see fig. 2.) The oblong slotf, like the slots 11 of the'bolts a, admits of the independent play of the doublb-tree, while the bolt'e forms a positive connection between the plates 6 and the strap. v t

This arrangement admits of the clevises E being thrown respectively further from and nearer to the bolt a of thedonble-tree, as the latter is moved from a right-angular position relatively with the draught-pole, the clevis at the forward end of the double-tree being brought nearer the draught-pole than the opposite end, and the leverage power of the forward end proportionably decreased. Hence the most ambitious horsewill, in consequence of the increased draught or labor put upon him by this automatic arrangement, check himself, while the less ambitions one, in consequence of the decreased labor, will be stimulated to pull ahead.

Strictly speaking, this automatic adjustment of the whifile trees is due to the turning-movement of the double-tree, the plates 6 in reality having no longitudinal Inovementin themselves, as they are connected by the bolt e to strap 0, and can swing or turn with the double-tree, but not being positively connected with it, or not turning from the same bolt a as a centre, (e being the bolt of the plates 5,) the result specified is obtained.

I would remark that the bolts which pass through the double-tree mayhe provided with friction-rollers, in order to avoid'friction in the working of the device.

I claim as new, and desire to secure by Letters Patent- The plates 6 b, sliding in grooves upon the top and bottom of the double-tree B in front of the band D, said plates 6 secured together at their ends and centres by the bolts 0 a, which slide in the slots df of tllddouhle-trfl,

all constructed and arranged toopei'ate as herein described for the purpose specified:

MOSES ADSIT.
